Therefore, in order to solve the defects in the prior art, the embodiments of the present invention provide a clamping device and a head-mounted device, which can adapt to a variety of clamped parts and ensure that the clamped parts are clamped at the center position of the device.

The following will describe in detail the implementation methods of the embodiments of the present invention in conjunction with the accompanying drawings and examples, so that the implementation process of how the embodiments of the present invention apply technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. The structure of the present invention is further described below in conjunction with the accompanying drawings.

Embodiment 1:

FIG. 1 is a schematic diagram of the planar structure of a clamping device according to an embodiment of the present invention, as shown in FIG. 1 .

An embodiment of the present invention provides a clamping device, including: a main slide plate 10 , a top slide plate 20 , at least one pair of clamping plates 30 , a scissor-type telescopic frame 40 and a locking mechanism 50 .

The top slide plate 20 is movably connected to the main slide plate 10. The paired clamping plates 30 are movably connected to the main slide plate 10, and the paired clamping plates 30 and the top slide plate 20 form a receiving space. The two ends of the scissor telescopic frame 40 are rotatably connected to the paired clamping plates 30, and the scissor telescopic frame 40 is rotatably connected to the top slide plate 20. The locking mechanism 50 is located on the moving path of the top slide plate 20.

When the top slide plate 20 moves in the first direction, the top slide plate 20 drives the scissor-type telescopic frame 40 to contract, and the scissor-type telescopic frame 40 drives the paired clamping plates 30 to move toward each other, so that the paired clamping plates 30 clamp the clamped parts accommodated in the accommodating space. At the same time, the top slide plate 20 drives the main slide plate 10 to move in the first direction through the paired clamping plates 30, so that the top slide plate 20 is connected to the locking mechanism 50, and the locking mechanism 50 locks the current position of the top slide plate 20.

The technical solution provided by the embodiment of the present invention is that the top slide plate 20 moves, and the top slide plate 20 drives the paired clamping plates 30 to move toward each other through the scissor-type telescopic frame 40, so that the paired clamping plates 30 can clamp the clamped parts. The accommodating space formed by the paired clamping plates 30 and the top slide plate 20 is adjustable so as to be able to adapt to a variety of clamped parts. Moreover, while the paired clamping plates 30 move synchronously, the top slide plate 20 drives the main slide plate 10 to move through the paired clamping plates 30, thereby ensuring that the clamped parts are clamped in the center position of the device. The clamping process is simple and quick, and the use is more humane, thereby improving the user experience.

Taking the clamped part as a mobile phone as an example, for example, referring to Figures 1 and 2, the mobile phone enters the accommodating space laterally along the direction of arrow A in Figures 1 and 2. First, the side wall of the mobile phone will contact the top slide plate 20, thereby driving the top slide plate 20 to move along the direction of arrow A, wherein the direction of arrow A is the first direction.

As shown in FIG. 2 , in the initial state, the paired clamps 30 are far from each other, and the top slide 20 is relatively close to the paired clamps 30. When the top slide 20 moves along the direction of arrow A (first direction), the top slide 20 drives the scissor telescopic frame 40 to shrink, and the scissor telescopic frame 40 drives the paired clamps 30 to move toward each other, that is, the paired clamps 30 move along the directions of arrows B and arrows C in FIG. 2 respectively, so that the paired clamps 30 clamp the mobile phone accommodated in the accommodation space, thereby achieving the purpose of clamping the mobile phone. After the paired clamps 30 clamp the mobile phone, the main slide 10, the top slide 20, the clamp 30 and the mobile phone become a whole. Then the mobile phone continues to move along the direction of arrow A, the mobile phone drives the top slide 20, the top slide 20 drives the clamp 30, and the clamp 30 drives the main slide 10, and the whole moves along the direction of arrow A until the top slide 20 is connected to the locking mechanism 50, and the locking mechanism 50 locks the current position of the top slide 20. At this point, the mobile phone clamping process is completed.

When releasing the mobile phone, the locking mechanism 50 is released to lock the top slide plate 20, and the main slide plate 10 and the top slide plate 20 will move in the direction opposite to the first direction until they return to the initial position. When the top slide plate 20 returns in the direction opposite to the first direction, the scissor-type telescopic frame 40 also returns from the contracted state to the expanded state, and the scissor-type telescopic frame 40 drives the paired clamping plates 30 to move in the opposite directions of arrows B and C to the initial positions respectively, completing the release of the mobile phone.

The clamping device provided by the embodiment of the present invention is further described in detail below.

Referring to Fig. 1 and Fig. 3, in an achievable embodiment of the present invention, the scissor telescopic frame 40 includes a plurality of scissor rods 41, and the plurality of scissor rods 41 are cross-hinged in sequence to form a plurality of end hinge points 42 and a plurality of middle hinge points 43. The scissor telescopic frame 40 is connected to the clamping plate 30 through the middle hinge points 43 located at both ends. The scissor telescopic frame 40 is rotatably connected to the top slide plate 20 through the end hinge points 42 facing the side of the top slide plate 20. Among them, the middle hinge point 43 is a hinge point located on the symmetry axis of the length direction of the scissor telescopic frame 40, and the end hinge points 42 are hinge points on both sides of the symmetry axis of the length direction of the scissor telescopic frame 40.

Connecting the clamping plate 30 through the middle hinge point 43 can maximize the opening and closing range of the scissor rods 41 at both ends of the scissor telescopic frame 40, thereby maximizing the telescopic range of the scissor telescopic frame 40, so as to be able to clamp a variety of different specifications of the supported parts. The top slide 20 is connected to the scissor telescopic frame 40 through the end hinge point 42 of the scissor telescopic frame 40. When the top slide 20 moves along the first direction, it can drive the scissor telescopic frame 40 to contract.

There are many ways to connect the top slide plate 20 to the scissors-type telescopic frame 40, among which one achievable way is that the top slide plate 20 is connected to the end hinge point 42 of the scissors-type telescopic frame 40 through a transfer shaft. Another achievable way is that, referring to Figures 1 and 3, at least one connecting rod 60 is provided on the top slide plate 20. One end of the connecting rod 60 is rotatably connected to the top slide plate 20, and the other end is rotatably connected to the end hinge point 42 of the scissors-type telescopic frame 40 facing the top slide plate 20. When the top slide plate 20 moves, the scissors-type telescopic frame 40 is driven to retract or expand through the connecting rod 60. The number of the connecting rod 60 can be one or more. When there is one connecting rod 60, the connecting rod 60 can be connected to the end hinge point 42 located in the middle of the scissors-type telescopic frame 40. When there are multiple connecting rods 60, when the connecting rods 60 are an even number, the multiple connecting rods 60 can be connected to the end hinge points 42 located symmetrically on both sides of the middle position of the scissors-type telescopic frame 40; when the connecting rods 60 are an odd number, the multiple connecting rods 60 can be connected to the hinge points located in the middle position of the scissors-type telescopic frame 40 and the end hinge points 42 located symmetrically on both sides of the middle position.

Furthermore, in order to realize that when the locking mechanism 50 releases the lock on the top slide plate 20, the scissors-type telescopic frame 40 can automatically return to the unfolded state, avoiding manual recovery by the user. In a feasible embodiment of the present invention, a first elastic member 44 is provided on the scissors-type telescopic frame 40. The two ends of the first elastic member 44 are respectively connected to the two end hinge points 42, wherein the two end hinge points 42 connecting the first elastic member 44 are mirror-symmetrical about the symmetry axis in the length direction of the scissors-type telescopic frame 40. When the top slide plate 20 drives the scissors-type telescopic frame 40 to contract, the first elastic member 44 provides a restoring force for the scissors-type telescopic frame 40. After the locking mechanism 50 releases the lock on the top slide plate 20, the scissors-type telescopic frame 40 returns to the unfolded state under the restoring force of the first elastic member 44.

For example, when the top slide plate 20 moves along the first direction, the top slide plate 20 drives the scissors-type telescopic frame 40 to contract, and the first elastic member 44 is deformed. At this time, the first elastic member 44 provides a restoring force, i.e., an unfolding force, for the scissors-type telescopic frame 40. When the locking mechanism 50 releases the lock on the top slide plate 20, the scissors-type telescopic frame 40 can return to its initial position, i.e., to the unfolded state, under the restoring force of the first elastic member 44. In the embodiment of the present invention, the first elastic member 44 includes but is not limited to a tension spring, a pressure spring, a spring sheet, etc. Taking the first elastic member 44 in Figures 1 and 3 as a tension spring as an example, when the top slide plate 20 moves along the first direction, the scissors-type telescopic frame 40 is driven to contract through the end hinge point 42 of the scissors-type telescopic frame 40. At this time, the tension spring is stretched, and the tension spring is deformed to generate a restoring force. When the locking mechanism 50 releases the lock on the top slide plate 20, the top slide plate 20 moves in the direction opposite to the first direction under the restoring force of the tension spring until it returns to the initial position. At this time, the scissors telescopic frame 40 returns to the expanded state under the restoring force of the tension spring.

Furthermore, in order to prevent the first elastic member 44 from occupying additional space of the clamping device, in an achievable embodiment of the present invention, a receiving groove 11 extending along the moving direction of the top slide 20 is provided on the main slide 10, and the first elastic member 44 is arranged in the receiving groove. The receiving groove 11 extends along the moving direction of the top slide 20, and the first elastic member 44 is deformed along the extending direction of the receiving groove 11, which does not occupy additional space and makes the structure of the entire device more compact.

Referring to Fig. 1, Fig. 3 and Fig. 4, in order to limit the moving direction of the top slide plate 20, in an achievable embodiment of the present invention, first positioning blocks 12 are respectively provided at positions corresponding to the opposite ends of the top slide plate 20 on the main slide plate 10. A first slideway 13 extending along the sliding direction of the top slide plate 20 is provided on the side of the first positioning block 12 facing the top slide plate 20. A first slide rail 21 matching the first slide rail 13 is provided on the top slide plate 20 at a position corresponding to the first slideway 13, and the first slide rail 21 can reciprocate along the extension direction of the first slideway 13. In an achievable manner, a groove recessed away from the top slide plate 20 is provided on the side of the first positioning block 12 facing the top slide plate 20, and the groove is the first slideway 13. Through the first slideway 13 on the first positioning block 12, it is limited that the first slide rail 21 can only move along the extension direction of the first slideway 13, and the first slide rail 21 is prevented from being displaced in other directions relative to the main slide plate 10. Furthermore, in order to prevent the first slide rail 21 from moving out of the first slideway 13 in the opposite direction of the first direction, a limiting portion is provided at one end of the first slideway 13 close to the clamping plate 30 to prevent the first slide rail 21 from moving out of the first slideway 13. Of course, the first slideway 13 can also be provided on the top slide plate 20, and the first slide rail 21 is provided on the first positioning block 12.

Further, in an achievable embodiment of the present invention, the top slide plate 20 includes a first bottom plate 22 and a first side plate 23 disposed on the first bottom plate 22. The first bottom plate 22 is rotatably connected to the scissor telescopic frame 40, and the first slide rail 21 is disposed at opposite ends of the first bottom plate 22. The first side plate 23 and the pair of clamping plates 30 form an accommodating space. After the clamped part enters the accommodating space, it abuts against the first side plate 23, and the top slide plate 20 is driven to move by the first side plate 23. The first bottom plate 22 is used to achieve connection with the scissor telescopic frame 40 and the first positioning block 12. In addition, in order to prevent the first side plate 23 from causing damage to the clamped part when the first side plate 23 contacts the clamped part, a first buffer layer is disposed on the side of the first side plate 23 that contacts the clamped part. The first buffer layer is elastic. When the first side plate 23 contacts the clamped part, the first buffer layer is squeezed and deformed, which offsets the force between the first side plate 23 and the clamped part, and prevents the clamped part from being squeezed and injured by the first side plate 23.

Further, in order to limit the moving direction of the clamping plate 30, referring to Fig. 1, Fig. 3 and Fig. 4, in an achievable embodiment of the present invention, second positioning blocks 14 are respectively provided at positions corresponding to the opposite ends of the clamping plate 30 on the main slide 10. A second slideway 15 extending along the sliding direction of the clamping plate 30 is provided on the side of the second positioning block 14 facing the clamping plate 30. A second slide rail matching the second slideway 15 is provided on the position of the clamping plate 30 corresponding to the second slideway 15, and the second slide rail can reciprocate along the extension direction of the second slideway 15. In an achievable manner, a groove recessed away from the clamping plate 30 is provided on the side of the second positioning block 14 facing the clamping plate 30, and the groove is the second slideway 15. Through the second slideway 15 on the second positioning block 14, it is limited that the second slide rail can only move along the extension direction of the second slideway 15, preventing the second slide rail from being displaced in other directions relative to the main slide 10. Of course, the second slideway 15 can also be provided on the clamping plate 30, and the second slide rail is provided on the second positioning block 14.

Furthermore, in order to prevent the first slide rail 21 from moving out of the first slideway 13 in the opposite direction of the first direction, in addition to setting the limiting portion, the second positioning block 14 can also prevent the first slide rail 21 from moving out of the first slideway 13. Specifically, one of the second positioning blocks 14 located at opposite ends of the clamping plate 30 is connected to an end of the first positioning block 12 close to the clamping plate 30, and extends beyond the first positioning block 12 to between the two first positioning blocks 12. The portion of the second positioning block 14 that exceeds the first positioning block 12 can limit the top slide plate 20, preventing the first slide rail 21 from moving out of the first slideway 13 in the opposite direction of the first direction.

Further, in an achievable embodiment of the present invention, optionally, the clamping plate 30 includes a second bottom plate 31 and a second side plate 32 arranged on the second bottom plate 31. The second bottom plate 31 is rotatably connected to the scissor telescopic frame 40, and the second slide rail is arranged at opposite ends of the second bottom plate 31. The paired second side plates 32 and the top slide plate 20 form an accommodating space. After the clamped piece enters the accommodating space, the paired clamping plates 30 clamp the clamped piece through the second side plates 32. In order to prevent the second side plates 32 from causing damage to the clamped piece when the second side plates 32 contact the clamped piece, a second buffer layer is arranged on the two sides of the second side plates 32 that contact the clamped piece. The second buffer layer is elastic. When the second side plates 32 contact the clamped piece, the second buffer layer is squeezed and deformed, which offsets the force between the second side plates 32 and the clamped piece, and prevents the clamped piece from being squeezed and injured by the second side plates 32. The second bottom plate 31 is used to realize the connection with the scissor telescopic frame 40 and the second positioning block 14. After the second base plate 31 is connected to the second slideway 15 on the second positioning block 14 through the second slide rail, the second base plate 31 can guide the clamping plate 30 to prevent the clamping plate 30 from shifting in direction when moving, thereby causing the force of the second side plate 32 clamping on the clamped part to shift, resulting in a loose clamping of the clamped part.

Further, in an achievable embodiment of the present invention, a second elastic member is provided on the main slide 10. One end of the second elastic member is fixed, and the other end is connected to the main slide 10. When the main slide 10 moves along the first direction, the first elastic member 44 provides a restoring force for the main slide 10. After the locking mechanism 50 releases the locking of the top slide 20, the main slide 10 returns to its initial position under the restoring force of the second elastic member. The second elastic member includes but is not limited to a tension spring, a pressure spring, a spring sheet, etc. Taking the second elastic member as a tension spring as an example, after the top slide 20 drives the paired clamps 30 to clamp the clamped member accommodated in the accommodation space, it continues to drive the main slide 10 to move along the first direction along the first direction. At this time, the main slide 10 pulls the tension spring (i.e., the second elastic member), causing the tension spring to deform and generate a restoring force. When the locking mechanism 50 releases the locking of the top slide 20, the main slide 10 moves in the opposite direction of the first direction under the restoring force of the tension spring until it returns to its initial position. Furthermore, in order to prevent the second elastic member from occupying additional space, in an achievable embodiment of the present invention, a mounting groove extending along the moving direction of the main slide 10 is provided on the main slide 10, and the second elastic member is arranged in the mounting groove. The mounting groove extends along the moving direction of the main slide 10, and the second elastic member is deformed along the extending direction of the mounting groove, which does not occupy additional space and makes the structure of the entire device more compact.

Continuing to refer to FIG. 1 and FIG. 3 , in order to further realize the integration of the clamping device, the clamping device further includes a fixing plate 70. The main slide 10 can be slidably arranged on the fixing plate 70. The locking mechanism 50 is arranged on the fixing plate 70. The various components of the clamping device can be integrated together through the fixing plate 70, so that the clamping device is integrated. At the same time, in order to prevent the main slide 10 from sliding out of the fixing plate 70 when moving in the opposite direction of the first direction, a stopper 71 is arranged on the fixing plate 70, and the stopper 71 is located on the path of the main slide 10 moving in the opposite direction of the first direction, so as to limit the maximum distance of movement of the main slide.

In order to limit the moving direction of the main slide 10, referring to Figures 1, 3 and 4, a third positioning block 72 is provided on the side of the fixed plate 70 facing the main slide 10. The third positioning block 72 is provided with a third slideway 73 extending along the sliding direction of the main slide 10. A third slide rail 16 matching the third slideway 73 is provided at a position on the main slide 10 corresponding to the third slideway 73, and the third slide rail 16 can reciprocate along the extension direction of the third slideway 73. In one achievable manner, a groove recessed away from the main slide 10 is provided on the side of the third positioning block 72 facing the main slide 10, and the groove is the third slideway 73. The third rail includes a connecting plate and a sliding plate, one end of the connecting plate is connected to the main slide 10, and the other end is connected to one end of the sliding plate, and the other end of the sliding plate extends to the third slideway 73. After the slide plate extends into the third slide 73, the third slide 73 limits the third slide rail 16 to move only along the extension direction of the third slide 73, and prevents the first slide rail 21 from moving in other directions relative to the main slide 10. At the same time, the stopper 71 can prevent the third slide rail 16 from moving out of the third slide 73 in the opposite direction of the first direction, so as to limit the maximum distance of movement of the main slide. Of course, the third slide 73 can also be set on the main slide 10, and the third slide rail 16 is set on the fixed plate 70.

In the embodiment of the present invention, the locking mechanism 50 can be implemented in a variety of ways. One possible implementation is that, referring to FIG. 1 and FIG. 3 , the locking mechanism 50 includes a locking rod 51 and a third elastic member 52. One end of the third elastic member 52 is fixed, and the other end is connected to the locking rod 51. A first buckle portion 53 is provided at one end of the locking rod 51, and a second buckle portion 24 used in conjunction with the first buckle portion 53 is provided at a position corresponding to the first buckle portion 53 on the top slide 20. The top slide 20 can be locked and unlocked by reciprocating movement of the locking rod 51. The top slide 20 can be automatically locked by the third elastic member 52, and the locking rod 51 can be automatically restored to the initial position after the main slide 10 is unlocked. Among them, the first buckle portion 53 and the second buckle portion 24 include but are not limited to hooks, and the hook portion of the first buckle portion 53 and the hook portion of the second buckle portion 24 have opposite bending directions.

For example, the third elastic member 52 includes but is not limited to a tension spring, a pressure spring and a spring sheet. For example, if the third elastic member 52 is a tension spring, one end of the tension spring is fixedly connected to the fixing plate 70, and the other end is connected to the locking rod 51. The locking rod 51 can reciprocate along the direction of the arrow D in FIG. 1. The top slide 20 drives the main slide 10 to move along the first direction. When the second buckle portion 24 on the top slide 20 contacts the first buckle portion 53, the second buckle portion 24 squeezes the first buckle portion 53, so that the locking rod 51 moves along the direction of the arrow D, and the third elastic member 52 is deformed. When the second buckle portion 24 exceeds the first buckle portion 53, under the action of the restoring force of the third elastic member 52, the locking rod 51 moves in the opposite direction of the arrow D, so that the first buckle portion 53 is engaged with the second buckle portion 24, so that the locking rod 51 locks the current position of the top slide 20.

When the user needs to unlock the top plate 20, the locking rod 51 can be moved along the direction of arrow D by external force to separate the second buckle portion 24 from the first buckle portion 53. At this time, the locking rod 51 unlocks the top plate 20. When the external force disappears, under the action of the restoring force of the third elastic member 52, the locking rod 51 moves along the opposite direction of arrow D and returns to its initial position.
