Example 1

As shown in FIG. 1 , an embodiment of the present invention discloses a robot competition hit detection prop, which is mainly used in robot competitions or games. In robot competitions or games, the robot competition hit detection prop can have different names according to different role settings, such as base, defense tower, outpost, etc., and the specific names are not limited here. The robot competition hit detection prop can sense the hits received by its designated parts in the competition or game.

As shown in Figures 1 and 2, the robot competitive hitting detection prop includes a main body 40, a hit part 50 and an elastic part 10; wherein the main body 40 can be used to support and install other parts of the robot competitive hitting detection prop. The bottom of the main body 40 can be placed or fixed on a competition venue or a game venue.

The struck member 50 is located at one end of the main body 40. The struck member 50 is used to receive the strike of the target object. The struck member 50 is provided with a detection device 90. The detection device 90 is used to detect the strike acting on the struck member 50.

In this embodiment, the struck part 50 can be used as an effective striking part of the robot competition striking detection prop specified in the competition or game rules. When the robot or other robot competition striking detection props successfully hits the struck part 50, some competition or game effects set by the game or competition rules can be generated, such as making the own side score points, making the opponent lose points, reducing the opponent's health, obtaining some kind of game reward, etc.

One end of the elastic member 10 is connected to the main body 40, and the other end is connected to the struck member 50. The elastic member 10 is used to block the vibration transmitted from the main body 40 to the struck member 50.

In order to prevent the impact or blow received by other parts of the robot competition striking detection props except the struck piece 50 from being transmitted to the struck piece 50 and detected by the detection device 90, the present embodiment uses the elastic member 10 to form a separable flexible connection between the main body 40 and the struck piece 50 of the robot competition striking detection props, that is, the main body 40 and the struck piece 50 can produce asynchronous displacement. Due to the elastic characteristics of the elastic member 10, the vibration generated when the main body 40 of the robot competition striking detection props is hit or impacted will not be directly transmitted to the struck piece 50, thereby effectively blocking the impact or blow acting on the main body 40. In this way, the impact or blow acting on the main body 40 will not be directly transmitted to the struck piece 50 and detected by the detection device 90 installed on the struck piece 50.

As shown in Figure 6, in this embodiment, the elastic member 10 includes an elastic segment 13 and a first connecting portion 11, and the first connecting portion 11 is connected to one end of the elastic segment 13 facing the main body 40. As shown in Figure 5, the first connecting portion 11 includes a first sub-portion 111 and a second sub-portion 112, and the first sub-portion 111 and the second sub-portion 112 are arranged on both sides of the elastic segment 13 along the radial direction of the elastic segment 13, and the first sub-portion 111 and the second sub-portion 112 are respectively connected to the main body 40.

The elastic member 10 of this embodiment is further provided with a first connecting portion 11 on the basis of the elastic section 13 of the existing elastic member 10. The elastic section 13 of the elastic member 10 has a certain elasticity, and produces corresponding deformation when subjected to external force, such as compression deformation, tensile deformation, etc., and can restore the original shape when the external force is removed. This embodiment utilizes the above-mentioned characteristics of the elastic member 10 to buffer and block external impacts such as blows or collisions acting on the main body 40.

In order not to affect the effect of the elastic member 10 in buffering and blocking external impacts, and to play a connecting role, the first connecting portion 11 is provided at the end of the elastic segment 13 in this embodiment. During connection, only the first connecting portion 11 can be used to contact the main body 40, and the elastic segment 13 can be free from interference from the main body 40, so that the flexible connection between the elastic member 10 and the main body 40 is achieved, and the influence of the connection with the main body 40 on the buffering and blocking performance of the elastic member 10 is avoided. The elastic member can be a spring.

In this embodiment, the first connecting portion 11 can be divided into two parts, namely, a first sub-portion 111 and a second sub-portion 112, and the two parts are respectively located on both sides of the radial direction of the elastic segment 13, so that the projections of the first sub-portion 111 and the second sub-portion 112 and the elastic segment 13 on the reference plane perpendicular to the axial direction of the elastic member 10 do not overlap with each other. The first sub-portion 111 and the second sub-portion 112 are connected to the main body 40 at different positions. Since the first sub-portion 111 and the second sub-portion 112 are located on both sides of the elastic segment 13, the connection between the elastic member 10 and the main body 40 can be realized on both sides of the elastic segment 13. Such a connection method is more stable and can effectively prevent the elastic member 10 from shifting to one side. And since the two sub-portions do not overlap with the elastic segment 13, the connection part and the elastic part will not interfere with each other, which will neither affect the connection nor the buffering and barrier properties of the elastic member 10.

As a preferred method, the first sub-section 111, the second sub-section 112 and the elastic section 13 of the elastic member 10 can be an integrated structure. In the above method, the first sub-section 111 and the second sub-section 112 can be directly formed by extending the tail end of the elastic section 13 of the elastic member 10, which not only ensures that the connecting portion and the elastic section 13 are reliably connected, but also enables the above three parts to be integrally formed.

In other embodiments, the first sub-portion 111 , the second sub-portion 112 and the elastic section 13 of the elastic member 10 may also be a split structure in which three parts are manufactured separately and then connected to each other.

In order to achieve the connection between the main body 40 and the elastic member 10 , the robot competitive striking detection prop in this embodiment further includes a first connecting member 20 , and the first sub-portion 111 or the second sub-portion 112 is connected to the main body 40 through the first connecting member 20 .

Since the first connecting portion 11 includes two sub-portions, two first connecting members 20 are also used when the same elastic member 10 is connected to the main body 40. One of the two first connecting members 20 is used to connect the main body 40 to the first sub-portion 111 of the elastic member 10, and the other is used to connect the main body 40 to the second sub-portion 112 of the elastic member 10.

In this embodiment, with the assistance of the first connecting member 20, the connection between the first connecting portion 11 and the main body 40 can be made more convenient and more reliable.

In order to achieve the connection between the elastic member 10 and the struck member 50, in the present embodiment, the elastic member 10 further includes a second connecting portion 12, which is connected to one end of the elastic segment 13 facing the struck member 50, and the second connecting portion 12 includes a third sub-portion 121 and a fourth sub-portion 122, and the third sub-portion 121 and the fourth sub-portion 122 are arranged on both sides of the elastic segment 13 along the radial direction of the elastic segment 13, and the third sub-portion 121 and the fourth sub-portion 122 are respectively connected to the struck member 50.

In order not to affect the effect of the elastic member 10 in buffering and blocking external impacts, and to play a connecting role, the second connecting portion 12 is provided at the end of the elastic section 13 in this embodiment. During connection, only the second connecting portion 12 can be used to contact the struck member 50, and the elastic portion and the struck member 50 can not interfere with each other, so that the flexible connection between the elastic member 10 and the struck member 50 is achieved, and the influence of the connection with the struck member 50 on the buffering and blocking performance of the elastic member 10 is avoided.

In this embodiment, the second connection portion 12 is divided into two parts, namely, a third sub-part 121 and a fourth sub-part 122, and the two parts are respectively located on both sides of the elastic segment 13 in the radial direction, so that the projections of the third sub-part 121 and the fourth sub-part 122 and the elastic segment 13 on the reference plane perpendicular to the axial direction of the elastic member 10 do not overlap with each other. The third sub-part 121 and the fourth sub-part 122 are connected to the struck member 50 at different positions. Since the third sub-part 121 and the fourth sub-part 122 are located on both sides of the elastic segment 13, the connection between the elastic member 10 and the struck member 50 can be realized on both sides of the elastic segment 13. Such a connection method is more stable and can effectively prevent the elastic member 10 from shifting to one side. And since the two sub-parts do not overlap with the elastic segment 13, the connection part and the elastic part will not interfere with each other, which will not affect the connection and the buffering and vibration barrier performance of the elastic member 10.

As a preferred method, the third sub-section 121, the fourth sub-section 122 and the elastic section 13 of the elastic member 10 can be an integrated structure. In the above method, the third sub-section 121 and the fourth sub-section 122 can be directly formed by extending the tail end of the elastic section 13 of the elastic member 10, which not only ensures that the connecting portion is reliably connected to the elastic section 13, but also enables the above three parts to be integrally formed.

In other embodiments, the third sub-portion 121 , the fourth sub-portion 122 and the elastic section 13 of the elastic member 10 may also be a split structure in which three parts are manufactured separately and then connected to each other.

The robot competition striking detection prop further includes a second connecting member 30 , and the third sub-part 121 or the fourth sub-part 122 is connected to the struck part via the second connecting member 30 .

Since the second connecting portion 12 includes two sub-portions, two second connecting members 30 are correspondingly used when the same elastic member 10 is connected to the struck member 50. One of the two second connecting members 30 is used to connect the struck member 50 to the third sub-portion 121 of the elastic member 10, and the other is used to connect the struck member 50 to the fourth sub-portion 122 of the elastic member 10.

In this embodiment, with the assistance of the second connecting member 30 , the connection between the second connecting portion 12 and the struck member 50 can be made more convenient and more reliable.

In this embodiment, the first connecting portion 11 and the second connecting portion 12 are provided at both ends of the elastic section 13 of the elastic member 10, and the first connecting member 20 used in conjunction with the first connecting portion 11 and the second connecting member 30 used in conjunction with the second connecting portion 12, so that the main body 40, the struck member 50 and the elastic member 10 can be conveniently and quickly installed from bottom to top, and the main body 40 and the struck member 50 after installation are flexibly connected through the elastic member 10. The above-mentioned method can reliably lock the two ends of the elastic member 10 with the main body 40 and the struck member 50, and avoid mutual interference between the connecting part and the elastic section 13 of the elastic member 10 while achieving the connection, so that after the connection, the main body 40 and the struck member 50 will not be completely separated, and the vibration between them can be effectively blocked.

As shown in FIG5 , in this embodiment, the first sub-section 111 includes a first segment 1111, a second segment 1112 and a third segment 1113 connected end to end. The first segment 1111 is a straight segment, the second segment 1112 is an arc segment, and the third segment 1113 is a straight segment. The first segment 1111 and the third segment 1113 extend in a direction parallel to the radial direction of the elastic member 10. The first segment 1111, the second segment 1112 and the third segment 1113 enclose a space through which the first end 21 of the first connecting member 20 can pass. After the first end 21 of the first connecting member 20 passes through the space, the first segment 1111, the second segment 1112 and the third segment 1113 cannot move arbitrarily in the radial direction under the limiting action of the first end 21, thereby realizing the radial positioning of the first sub-section 111 by the first connecting member 20.

Similarly, in this embodiment, the second sub-section 112 includes a fourth segment 1121, a fifth segment 1122 and a sixth segment 1123 connected end to end. The third segment 1113 is a straight segment, the fourth segment 1121 is an arc segment, and the fifth segment 1122 is a straight segment. The fourth segment 1121 and the sixth segment 1123 extend in a direction parallel to the radial direction of the elastic member 10. The fourth segment 1121, the fifth segment 1122 and the sixth segment 1123 enclose a space through which the first end 21 of the first connecting member 20 can pass. After the first end 21 of the first connecting member 20 passes through the space, the fourth segment 1121, the fifth segment 1122 and the sixth segment 1123 cannot move arbitrarily in the radial direction under the limiting action of the first end 21, thereby realizing the radial positioning of the second sub-section 112 by the first connecting member 20.

The third segment 1113 of the first sub-section 111 and the fourth segment 1121 of the second sub-section 112 are connected so that the first sub-section and the second sub-section 112 form a whole, which is the first connecting portion 11, and the two arcs of the second segment 1112 and the fifth segment 1122 face each other. At this time, the shape of the first connecting portion 11 is a semi-closed runway. The two first connecting members 20 pass through the first sub-section 111 and the second sub-section 112 respectively. The above structure allows the first sub-section 111 and the second sub-section 112 to cooperate with each other when achieving connection positioning.

As shown in FIG7 , when the elastic member 10 shows a tendency to move toward the w1 direction in the figure, the first segment 1111 of the first sub-portion 111 and the sixth segment 1123 of the second sub-portion 112 can simultaneously prevent the elastic member 10 from deviating toward the w1 direction from both sides of the elastic member 10. When the elastic member 10 shows a tendency to move toward the w2 direction in the figure, the third segment 1113 of the first sub-portion 111 and the fourth segment 1121 of the second sub-portion 112 can simultaneously prevent the elastic member 10 from deviating toward the w2 direction from both sides of the elastic member 10. When the elastic member 10 shows a tendency to move toward the w3 direction in the figure, the second segment 1112 of the first sub-portion 111 can prevent the elastic member 10 from deviating toward the w3 direction. When the elastic member 10 shows a tendency to move toward the w4 direction in the figure, the fifth segment 1122 of the second sub-portion 112 can prevent the elastic member 10 from deviating toward the w4 direction.

Therefore, the connecting portion adopts the structure of this embodiment to limit the displacement of the elastic member 10 from the aforementioned directions, and sufficient space can be left between the second segment 1112 and the fifth segment 1122 to facilitate the axial passage of the first connecting member 20 or other components along the elastic member 10, which facilitates assembly and achieves reliable connection.

Similarly, the third sub-section 121 and the fourth sub-section 122 of the second connecting portion 12 may also adopt a structure in which two straight line segments are connected end to end with an arc segment, and their shapes may be exactly the same as the first sub-section 111 and the second sub-section 112 of the aforementioned first connecting portion 11, and their effects are also the same, which will not be elaborated here.

When the first connection portion 11 and the second connection portion 12 adopt the same shape, the angles of the first connection portion 11 and the second connection portion 12 in the circumferential position can be staggered, and the staggered angle range is 85 degrees to 95 degrees. The staggered angles of the first connection portion 11 and the second connection portion 12 can increase the space for assembly operation, thereby making assembly more convenient. At the same time, the positions of the four connection points of the elastic member can be dispersed to improve the stability of the connection.

Example 2

As shown in Figures 4 and 6, in this embodiment, the first connecting member 20 may include a first end 21 and a second end 22 arranged opposite to each other, the first sub-portion 111 is formed with a first cavity 113 for the first end 21 to pass through, and the second sub-portion 112 is formed with a second cavity 114 for the first end 21 to pass through, and the first end 21 is connected to the main body 40 after passing through the first cavity 113 or the second cavity 114, and the first sub-portion 111 or the second sub-portion 112 is limited between the main body 40 and the second end 22.

The first end 21 and the second end 22 can be arranged at both ends of the first connecting member 20 along the axial direction of the elastic section 13, that is, the first end 21 is located at the position of the first connecting member 20 facing the striking member, and the second end 22 is located at the position of the first connecting member 20 facing the main body 40. When the first sub-section 111 is connected to the main body 40 through the first connecting member 20, the first end 21 of the first connecting member 20 passes through the first cavity 113, wherein a part of the first end 21 passes through the first cavity 113, and the part that passes through can be used to form a connection with the main body 40. The second end 22 of the first connecting member 20 can adopt a cross-section with a larger coverage range than the first end 21. For example, the projection of the first end 21 on the reference plane is located in the first cavity 113, so that the first end 21 can vertically pass through the first cavity 113, and the projection of the second end 22 on the reference plane at least partially overlaps with the first sub-section 111, so that the second end 22 can limit the movement of the first sub-section 111 relative to the main body 40 along the axial direction of the elastic section 13.

Similarly, when the second sub-section 112 is connected to the main body 40 through the first connector 20, the first end 21 of the first connector 20 passes through the first cavity 113, wherein a portion of the first end 21 passes through the second cavity 114, and the portion that passes through can be used to form a connection with the main body 40. The second end 22 of the first connector 20 can adopt a cross-section that covers a larger range than the first end 21. For example, the projection of the first end 21 on the reference plane is located in the first cavity 113, so that the first end 21 can vertically pass through the first cavity 113, and the projection of the second end 22 on the reference plane at least partially overlaps with the second sub-section 112, so that the second end 22 can limit the second sub-section 112 from moving relative to the main body 40 along the axial direction of the elastic section 13.

The above-mentioned method can be used to conveniently and quickly connect the first sub-section 111 and the second sub-section 112 to the main body 40, respectively. The first end 21 of the first connector 20 reliably limits the radial position of the first sub-section 111 or the second sub-section 112 by passing through the first cavity 113 or the second cavity 114, and at the same time, the second end 22 located outside the first cavity 113 or the second cavity 114 reliably limits the axial position of the first sub-section 111 or the second sub-section 112. In this embodiment, the first end 21 and the second end 22 of the first connector 20 simultaneously limit the first sub-section 111 and the second sub-section 112 from different positions and different directions, so that the first sub-section 111 and the second sub-section 112 form a stable and reliable connection with the main body 40. And the first connector 20 can achieve a reliable connection between the elastic member 10 and the main body 40 by only contacting the first sub-section 111 or the second sub-section 112 of the elastic member 10, so that the performance of the elastic section 13 will not be affected.

As one of the implementation modes, in this embodiment, a limiting groove with at least one end open is provided on one side of the second connecting member facing the second connecting part, and the second connecting part is inserted into the limiting groove through the opening. The aforementioned limiting groove can be formed by a limiting plate and the bottom surface of the second connecting part, that is, in this embodiment, the second connecting part also includes a limiting plate, and the limiting plate extends from the side of the second connecting member facing the second connecting part along the axial direction of the shock-absorbing elastic member to a predetermined length, then bends to a direction perpendicular to the axial direction of the shock-absorbing elastic member, and continues to extend along this direction to a certain length. The gap between the limiting plate and the second connecting part is the aforementioned limiting groove, wherein the length of the limiting plate extending along the axial direction of the shock-absorbing elastic member can be determined according to the size of the second connecting part along the axial direction of the shock-absorbing elastic member, so that the limiting groove between the limiting plate and the second connecting part can just accommodate the second connecting part.

As another implementation, in this embodiment, the second connecting member 30 includes a third end and a fourth end arranged opposite to each other, the third sub-portion 121 forms a third cavity 123 for the third end to pass through, and the fourth sub-portion 122 forms a fourth cavity 124 for the third end to pass through, and the third end is connected to the main body 40 after passing through the third cavity 123 or the fourth cavity, and the third sub-portion 121 or the fourth sub-portion 122 is limited between the main body 40 and the fourth end.

The third end and the fourth end can be arranged at both ends of the second connecting member 30 along the axial direction of the elastic section 13, that is, the third end is located at the position of the second connecting member 30 facing the main body 40, and the fourth end is located at the position of the second connecting member 30 facing the struck member 50. When the third sub-portion 121 is connected to the struck member 50 through the second connecting member 30, the third end of the second connecting member 30 passes through the third cavity, wherein a part of the third end passes through the third cavity, and the part that passes through can be used to form a connection with the struck member 50. The fourth end of the second connecting member 30 can adopt a cross-section with a larger coverage range than the third end. For example, the projection of the third end on the reference plane is located in the third cavity 123, so that the third end can vertically pass through the third cavity, and the projection of the fourth end on the reference plane at least partially overlaps with the third sub-portion 121, so that the fourth end can limit the movement of the third sub-portion 121 relative to the struck member 50 along the axial direction of the elastic section 13.

Similarly, when the fourth sub-section 122 is connected to the struck member 50 through the second connecting member 30, the third end of the second connecting member 30 passes through the third cavity, wherein a portion of the third end passes through the fourth cavity 124, and the portion that passes through can be used to form a connection with the main body 40. The fourth end of the second connecting member 30 can adopt a cross-section that covers a larger range than the third end. For example, the projection of the third end on the reference plane is located in the third cavity, so that the third end can vertically pass through the third cavity, and the projection of the fourth end on the reference plane at least partially overlaps with the fourth sub-section 122, so that the fourth end can limit the movement of the fourth sub-section 122 relative to the struck member 50 along the axial direction of the elastic section 13.

The above-mentioned method can be used to conveniently and quickly connect the third sub-section 121 and the fourth sub-section 122 to the struck member 50. The third end of the second connecting member 30 reliably limits the radial position of the third sub-section 121 or the fourth sub-section 122 by passing through the third cavity or the fourth cavity 124, and reliably limits the axial position of the third sub-section 121 or the fourth sub-section 122 by using the fourth end located outside the third cavity or the fourth cavity 124. In this embodiment, the third sub-section 121 and the fourth sub-section 122 are simultaneously limited from different positions and directions by the third end and the fourth end of the second connecting member 30, so that the third sub-section 121 and the fourth sub-section 122 are stably and reliably connected to the struck member 50. Moreover, the second connecting member 30 can realize the reliable connection between the elastic member 10 and the main body 40 by only contacting the third sub-section 121 or the fourth sub-section 122 of the elastic member 10, so that the performance of the elastic section 13 will not be affected.

As shown in FIG. 8 , in this embodiment, the main body 40 further includes a fixing member 60 , which is located at one end of the main body 40 facing the striking member 50 , and a limiting portion 61 is provided on the fixing member 60 , and the limiting portion 61 passes through the elastic member 10 and the second connecting member 30 along the axial direction of the elastic member 10 .

In this embodiment, the limiting portion 61 provided on the fixing member 60 passes through the elastic member 10 and the second connecting member 30 to limit the radial position of the elastic member 10 and the second connecting member 30, which does not affect the telescopic performance of the elastic member 10 and can effectively limit the position. In this embodiment, the length of the limiting portion 61 in the axial direction can be greater than the sum of the lengths of the elastic member 10 and the second connecting member 30, so that the limiting portion 61 can limit the position of each axial position on the elastic member 10 and the second connecting member 30, thereby forming a more stable and reliable connection between the elastic member 10 and the main body 40.

As a preferred embodiment, the limiting portion 61 is in the shape of a truncated cone, and the diameter of the cross section of the limiting portion 61 at one end close to the fixing member 60 is larger than the diameter of the cross section of the limiting portion 61 at one end away from the fixing member 60. A limiting strip 62 is also arranged around the limiting portion 61, and the limiting strip 62 extends from the peripheral wall of the truncated cone toward the outside of the truncated cone, and the bottom of the limiting strip 62 is flush with the end of the truncated cone with a larger diameter, and the length of the limiting strip 62 is less than the length of the truncated cone. The above-mentioned setting of the limiting strip 62 can increase the structural strength of the limiting portion 61 and improve the reliability of the positioning of the limiting portion 61. The bottom of the limiting strip 62 can also be used in conjunction with the first connecting member 20, and the radial position of the elastic member 10 can be limited from the central part of the elastic member 10 and the outer periphery of the elastic member 10 at the same time, respectively, so that the connection between the installed elastic member 10 and the main body 40 is more stable and reliable.

As shown in Figures 2 and 3, as an improved implementation, in this embodiment, the robot competition hitting detection props also include an anti-slip component 70, and the anti-slip component 70 is connected to the fixing component 60 at a position where the elastic component 10 is at a preset distance from the second connecting component 30 along the axial direction, and the anti-slip component 70 is located on the side of the second connecting component 30 facing the hitting component 50.

The preset distance ranges from 1.3 mm to 2.7 mm. When the struck member 50 is pulled upward, the elastic member 10 is easily damaged. In this embodiment, an anti-slip member 70 is provided above the second connecting member 30 to limit the second connecting member 30. When the struck member 50 is pulled upward, the elastic member 10 moves with the second connecting member 30 to the position where the second connecting member 30 abuts against the anti-slip member 70. The second connecting member 30 is blocked by the anti-slip member 70 and cannot continue to move upward. At this time, the elastic member 10 will not be stretched further, thereby effectively avoiding damage to the elastic member 10.

In this embodiment, a control circuit 100 may be provided inside the main body 40, and the control circuit 100 may receive the detection signal sent by the detection device 90 and send the detection signal to the competition system for scoring. The detection device 90 may be a PCB board with a detection sensor.

Example 3

As shown in FIG. 1 to FIG. 3 , this embodiment is improved on the basis of the previous embodiment. In this embodiment, the robot competition striking detection prop further includes an anti-collision device, which surrounds the main body 40 at one end away from the striking member 50 .

This embodiment reduces the impact or shock to the robot competition striking detection prop main body 40 from all directions during the game or game by using the anti-collision device surrounding the main body 40. On the one hand, it can protect the robot competition striking detection prop and prevent damage, and on the other hand, it can effectively reduce the impact of the vibration of the main body 40 on the struck part 50, avoiding interference with the detection effect of the corresponding detection device 90, thereby affecting the accuracy of the detection.

In this embodiment, the anti-collision device includes an anti-collision component 81 and a shock absorbing component 82. The anti-collision component 81 is a frame structure with a cavity. The shock absorbing component 82 surrounds the end of the main body 40 away from the striking component 50 and is located between the frame and the main body 40.

The frame size of the anti-collision member 81 can be slightly larger than the size of the bottom of the main body 40, so that after the bottom of the main body 40 is placed in the cavity, there is still a gap around the bottom of the main body 40 between the main body 40 and the anti-collision member 81, and the shock absorbing member 82 is arranged at the gap position and surrounds the main body 40. The anti-collision member 81 can increase the stability of the bottom of the robot competitive hitting detection prop. When the bottom of the robot competitive hitting detection prop is hit or impacted, the shock absorbing member 82 can play a buffering role in time, so that the vibration finally transmitted to the shock absorbing member 82 is greatly reduced.

The struck member 50 includes an upper shell 51 and a lower shell 52 . The upper shell 51 is provided with a cavity, and the bottom of the cavity is provided with an opening. The lower shell 52 is connected to the upper shell 51 at the bottom of the upper shell 51 .

As shown in Figures 2 and 3, when assembling the robot competition hitting detection props of this embodiment, first put the elastic member 10 directly into the positioning groove of the fixing member 60, and buckle the first connecting member 20; then put the lower shell 52 down vertically, so that the second connecting part 12 of the elastic member 10 passes through the lower shell 52, and then buckle the second connecting part 12 of the elastic member 10 into the groove at the bottom of the second connecting member 30, and then fix the second connecting member 30 and the lower shell 52, and then install the PCB board in the hitting member 50 and the upper shell 51 in turn.
