Detailed Description
To further illustrate the display device separated wall hanging according to the embodiment of the present invention, the following description is made in detail with reference to the accompanying drawings.
Referring to fig. 2-3, the display device separated wall hanging according to the embodiment of the present invention includes: a pair of wall hanging units as shown in fig. 3, a hanging shaft 4 arranged on the rear case 3 of the display device and used for matching with the corresponding wall hanging unit as shown in fig. 2, and a pair of wall hanging units as shown in fig. 3, namely a first wall hanging unit 10 and a second wall hanging unit 20; since the first wall hanging unit 10 and the second wall hanging unit 20 have the same structure, the structure of each wall hanging unit will be described with reference to the first wall hanging unit 10 shown in fig. 5 to 9.
Referring to fig. 4, a locking cavity is disposed in the wall-mounted unit; referring to fig. 6, a notch 133 is formed in the wall-hanging single body 10, which enables the limiting end of the hanging shaft 4 to enter the locking cavity, and referring to fig. 5 and fig. 9-12, a hanging shaft slideway communicated with the locking cavity is formed in the wall-hanging single body, the wall-hanging slideway comprises a self-locking guide slideway 200 and a hanging shaft mounting hole 100 which are sequentially communicated, and the self-locking guide slideway 200 is connected with the notch 133 into a whole;
referring to fig. 9 and 13, when the hanging scroll 4 enters the hanging scroll slideway or the hanging scroll 4 leaves the hanging scroll slideway, the sliding direction of the hanging scroll 4 in the hanging scroll mounting hole 100 is different from the sliding direction of the self-locking guide slideway 200.
In operation, referring to fig. 2-3, according to the size of the display device, the distance L between the pair of wall-hanging monomers on the wall is determined, and then the pair of wall-hanging monomers is fixed on the wall according to the determined distance L between the pair of wall-hanging monomers on the wall. In addition, the distance L between the hanging shafts 4 in the pair of single wall hanging units is the distance between the hanging shafts 4 in the pair of single wall hanging units when the hanging shafts 4 are located in the hanging shaft mounting holes 100 and in the working state.
Referring to fig. 13, a limit end of the hanging shaft 4 disposed on the rear housing 3 of the display device extends into the locking cavity from the notch, the hanging shaft 4 slides along the self-locking guiding slideway 200, and then changes the sliding direction to enter the hanging shaft mounting hole 100, so that the hanging shaft 4 is in a working state, and the hanging of the display device 4 on the wall is completed.
Referring to fig. 14, when the hanging shaft 4 tends to be separated from the hanging shaft slideway, the hanging shaft 4 needs to receive a force (which may also be a resultant force of various forces, which may be generated during the twisting process of the display device or the wall-mounted unit) for urging the hanging shaft 4 to be separated from the hanging shaft mounting hole 100, so that the hanging shaft 4 located in the hanging shaft mounting hole 100 slides from the hanging shaft mounting hole 100, then changes the moving direction, slides on the self-locking guide slideway 200, and finally rolls out from the hanging shaft slideway, but under the non-manual action, the force urging the hanging shaft 4 to be separated from the hanging shaft mounting hole 100 is small, and the sliding direction of the hanging shaft cannot be changed; therefore, the hanger shaft 4 is locked in the hanger shaft slide passage and cannot be disengaged. If the hanging scroll 4 is to be taken off from the hanging scroll slideway, a force which can change the direction along with the change of the sliding direction of the hanging scroll 4 is required to be applied to the hanging scroll 4, and the force needs to be large enough to overcome the gravity of the hanging scroll and the friction force applied to the hanging scroll by the slideway, so that the hanging scroll 4 can be smoothly taken off from the hanging scroll slideway.
As can be seen from the specific working process, in the display device separation type wall hanging provided by this embodiment, a locking cavity is arranged in the wall hanging monomer, the wall hanging monomer is provided with a notch 133 enabling the limit end of the hanging shaft 4 to enter the locking cavity and a wall hanging slideway communicated with the locking cavity, the wall hanging slideway is composed of a self-locking guide slideway 200 and a hanging shaft mounting hole 100 which are connected into a whole, and an inlet of the self-locking guide slideway 200 is communicated with the notch 133, so that after the limit end of the hanging shaft 4 enters the locking cavity from the notch 133, the hanging shaft 4 can enter the hanging shaft mounting hole 100 along the self-locking guide slideway 200, and thus enters a working state; moreover, when the hanging scroll 4 enters the hanging scroll slideway or is separated from the hanging scroll slideway, the sliding direction of the hanging scroll 4 in the hanging scroll mounting hole 100 is different from that of the self-locking guide slideway 200, so that when the hanging scroll 4 has a tendency to be separated from the hanging scroll slideway, the hanging scroll 4 can be separated only by changing the sliding direction, that is, the force applied to the hanging scroll 4 must be large enough, and the direction of the force can be changed according to whether the hanging scroll 4 is in the hanging scroll mounting hole 100 or the self-locking guide slideway 200, so as to change the sliding direction of the hanging scroll 4, and the hanging scroll 4 can be separated from the hanging scroll slideway; and under the non-artificial effect, the power that hanging axle 4 generally received is less, and the direction is unstable moreover, and it can't change hanging axle 4's slip direction at all, therefore, in the display device hanging that this embodiment provided, utilize the change of the slip direction of hanging axle slide that hanging axle seted up on hanging monomer just can improve display device and hang the reliability of adorning on the wall body, and need not to rely on locking parts such as screw or pin, very big simplification display device hanging's structure.
In addition, when the pair of wall hanging monomers with simple structures is arranged on the wall body, the distance between the pair of wall hanging monomers on the wall body can be adjusted according to the size of the display device, so that the requirement of hanging the display devices with various sizes on the wall body is met; the pair of wall hanging monomers has a simple structure, and can replace the combined wall hanging formed by a plurality of groups of wall hanging monomers at present, so that the separated wall hanging of the display device provided by the embodiment has small volume and low manufacturing cost.
It should be noted that, in the above embodiments, the hanging scroll 4 has many specific forms, for example, in order to reduce the friction between the hanging scroll 4 and the hanging scroll slideway, the hanging scroll with the roller may have other structures which can be fixed on the rear case 3 of the display device and can slide in the hanging scroll slideway. For example, referring to fig. 2, the hanging shaft 4 may be disposed on the rear housing 3 of the display device through a first fixing member 5, and the first fixing member 5 may be a common fixing member such as a screw, but is not limited thereto.
In addition, the cushion block 7 can be arranged on the rear shell 3 of the display device, so that on one hand, the distance between the rear shell 3 hung on the display device and a wall can be adjusted, the gap between the display device and the wall is increased, the rear shell 3 of the display device can have a sufficient heat dissipation space, and the heat dissipation efficiency of the display device is improved; on the other hand, the perpendicularity of the display panel of the display device (namely the included angle between the plane where the display panel of the display device is located and the plane where the wall body is located) can be adjusted by adjusting the shape and the volume of the cushion block 7, so that the display panel of the display device can adapt to the viewing angle of a user, and the visual experience of the user is improved; the material of the cushion block 7 may be EVA (ethylene vinyl acetate) or other realizable materials.
When the display device is hung on the wall by using the above-mentioned embodiment, since the display device separation type wall is located between the rear case and the wall of the display device, in a specific operation, the hanging shaft 4 provided on the rear case 3 of the display device needs to be carefully aligned with the self-locking guide chute 200 at the notch 133, so that the hanging shaft 4 can enter the hanging shaft chute. In order to facilitate the hanging shaft 4 arranged on the rear shell 3 of the display device to more conveniently enter the self-locking guide slideway 200, the hanging shaft slideway in the above embodiment further comprises a guide inlet slideway 300 which can enable the hanging shaft 4 to enter the self-locking guide slideway 200 from the notch 133, the inlet of the guide inlet slideway 300 is a large-opening end, the outlet is a small-opening end, the inlet of the guide inlet slideway 300 is communicated with the notch 133, and the outlet of the guide inlet slideway 300 is communicated with the self-locking guide slideway 200. Since the guide entrance chute 300 enables the hanging scroll 4 to enter the self-locking guide chute 200 from the notch 133, and the entrance of the guide entrance chute 300 is a large-mouth end, and the exit is a small-mouth end, the hanging scroll 4 can enter the self-locking guide chute 200 from the entrance of the guide entrance chute 300 located at the notch without special alignment.
Referring to fig. 9 to 13, in order to further improve the hanging reliability of the display device on the wall and reduce the manual operation, after the change gear 4 enters the guide entrance slideway 300 through the gap, the change gear finally enters the hanging shaft mounting hole 100 through the guide entrance slideway 300 and the self-locking guide slideway 200 under the action of gravity without manual interference; the inlet of the self-locking guide slideway 200 of the above embodiment is communicated with the outlet of the guide inlet slideway 300 through a first arc-shaped transition slideway 400 which can change the rotation direction of the hanging shaft 4; and/or the presence of a gas in the gas,
the outlet of the self-locking guide slideway 200 is communicated with the hanging shaft mounting hole 100 through a second arc-shaped transition slideway 500 which can change the rotation direction of the hanging shaft 4.
Since the principle of the first arc-shaped transition chute 400 for changing the rotation direction of the hanging shaft 4 is the same as the principle of the second arc-shaped transition chute 500 for changing the rotation direction of the hanging shaft, only how the first arc-shaped transition chute 400 changes the rotation direction of the hanging shaft 4 will be described below.
Referring to fig. 13, when a big end of the hanging shaft 4 disposed on the rear housing 3 of the display device extends into the guiding entrance slideway 300 from the notch, the hanging shaft 4 rolls along the guiding entrance slideway 300 in the direction indicated by the arc arrow a in fig. 13 under the action of its own weight, and when entering the self-locking guiding slideway 200, the rolling direction of the hanging shaft 4 changes and rolls in the direction indicated by the arc arrow b in fig. 13, and when the hanging shaft 4 rolls out from the exit of the self-locking guiding slideway 200 and enters the hanging shaft mounting hole 100, the hanging shaft 4 is in a working state, thereby achieving the purpose of hanging the display device 4 on the wall.
Referring to fig. 13 and 14, the reason why the first arc-shaped transition chute 400 can change the rotation direction of the hanging shaft 4 is that when the hanging shaft 4 enters the hanging shaft chute, and the hanging shaft 4 enters the first arc-shaped transition chute 400 from the guide entrance chute 300, a force is applied to the hanging shaft 4 by the inner wall of the first arc-shaped transition chute 400, so that the rotation direction of the hanging shaft 4 is changed, and the hanging shaft enters the self-locking guide chute 200 through the first arc-shaped transition chute 400; in the process that the hanging scroll 4 is separated from the hanging scroll slideway, at the moment that the hanging scroll 4 enters the first arc-shaped transition slideway 400 from the inlet of the self-locking guide slideway 200, the inner wall of the first arc-shaped transition slideway 400 applies a force to the hanging scroll 4, so that the rotation direction of the hanging scroll 4 is changed, and the hanging scroll enters the guide inlet slideway 300 through the first arc-shaped transition slideway 400. In addition, no matter the hanging scroll 4 enters the hanging scroll slide way or leaves the hanging scroll slide way, the force applied by the inner wall of the first arc-shaped transition slide way 400 to the hanging scroll 4 is the reaction force of the force when the hanging scroll 4 rotates in the original direction, and the larger the force for driving the hanging scroll 4 to rotate in the original direction is, the faster the rotating speed of the hanging scroll 4 is, and the larger the force applied by the inner wall of the first arc-shaped transition slide way 400 to the hanging scroll 4 is; therefore, when the hanging scroll 4 enters the hanging scroll slideway, the force applied by the inner wall of the first arc-shaped transition slideway 400 to the hanging scroll is in direct proportion to the rotating speed of the hanging scroll 4 in the guide entrance slideway 300; when the hanging shaft 4 is separated from the hanging shaft slideway, the force applied by the inner wall of the first arc-shaped transition slideway 400 to the hanging shaft 4 is in direct proportion to the rotating speed of the hanging shaft 4 in the self-locking guide slideway 200.
Through the analysis, the hanging scroll 4 can be quickly moved into or out of the hanging scroll slideway only by applying a large force to the hanging scroll 4, so that the inner wall of the first arc-shaped transition slideway 400 can apply a large force to the hanging scroll, and the hanging scroll 4 still has a large rotating speed after the rotating direction is changed, thereby quickly moving into the hanging scroll slideway; when the hanging scroll 4 is required to be separated from the hanging scroll slideway, large force must be applied to the hanging scroll 4 to ensure that the hanging scroll 4 is separated from the hanging scroll slideway, and because the force applied to the hanging scroll 4 is small under the non-artificial action, the force is not enough to change the rotation direction of the hanging scroll, certain difficulty is increased for the hanging scroll 4 to be separated from the hanging scroll slideway, and the reliability of the display device hung on a wall body is improved.
The hanging scroll slideway in the above embodiment includes the guide entrance slideway 300, the self-locking guide slideway 200 and the hanging scroll mounting hole 100 which are sequentially communicated, so that the accuracy of the hanging scroll 4 entering (or being mounted to) the hanging scroll slideway is improved through the structural design of the guide entrance slideway 300, the self-locking guide slideway 200 and the hanging scroll mounting hole 100, and the hanging scroll 4 is difficult to be separated from the hanging scroll slideway under the non-artificial action.
Referring to fig. 5-7 and 9-12, the guide entrance chute 300 in the above embodiment includes a slope guide portion 301 and a vertical guide portion 302 parallel to the gravity direction of the hanging shaft 4, and the slope guide portion 301 and the vertical guide portion 302 communicate with the entrance and the notch 133 of the first arc-shaped transition chute 400. Thus, after one limit end of the hanging shaft 4 enters the locking cavity from the notch 4, the hanging shaft can move along the slope guide part 301 under the action of gravity. As shown in fig. 13, when the hanging shaft 4 moves in the guiding entrance slide 300 to enter the first arc-shaped transition slide 400, if the hanging shaft 4 has a tendency to be pushed out of the hanging shaft slide, because the vertical guiding portion 302 is parallel to the gravity direction of the hanging shaft 4, after the hanging shaft 4 meets the vertical guiding portion 302, if the hanging shaft slide still continues to be pushed out of the hanging shaft slide, the hanging shaft 4 can only overcome its own gravity to move upward along the vertical guiding portion 302, and therefore, the magnitude of the force for pushing the hanging shaft 4 to move upward along the vertical guiding portion 302 must be greater than the gravity of the hanging shaft 4, whereas if the guiding entrance slide 300 formed by the vertical guiding portion 302 and the slope guiding portion 301 is similar to a trumpet shape, and the limiting end of the trumpet shape is the entrance of the guiding entrance slide 300, the force overcome by the hanging shaft 4 to push out of the hanging shaft slide along the vertical guiding portion 302 is substantially a component of the gravity, the component force is smaller than the gravity of the hanging shaft 4; therefore, when the vertical guide portion 302 in this embodiment is parallel to the gravity direction of the hanging shaft 4, the hanging shaft 4 moves upward along the vertical guide portion 302 to be difficult to flush out the hanging shaft slideway, and the probability that the hanging shaft 4 flushes out the hanging shaft slideway is reduced; in other words, when the hanging scroll 4 tends to be flushed out of the hanging scroll slideway, the vertical guiding portion 302 can correct the rotation track of the hanging scroll 4 when the hanging scroll 4 enters the hanging scroll slideway, so that the hanging scroll 4 can be accurately installed in place.
In addition, when the hanging scroll 4 is rushed out of the hanging scroll slide way, the hanging scroll needs to move upwards along the vertical guide part 302, and the moving time of the hanging scroll rushing out of the hanging scroll slide way can be increased by enabling the height of the slope guide part 301 to be smaller than that of the vertical guide part 302, so that the difficulty of the hanging scroll 4 moving upwards along the vertical guide part 302 to rush out of the hanging scroll slide way is further increased.
Secondly, in order to improve the hanging reliability of the display device on the wall, please refer to fig. 12, the self-locking guiding slideway 200 includes a plurality of linear self-locking parts; the adjacent linear self-locking parts are communicated through arc-shaped self-locking parts which can change the rotation direction of the hanging shaft 4; the outlet of the first arc-shaped transition chute 400 is communicated with the closest one of the linear self-locking parts to the outlet of the first arc-shaped transition chute 400.
Because the adjacent linear self-locking parts are communicated through the arc self-locking parts capable of changing the rotation direction of the hanging shaft 4, when the hanging shaft 4 enters the self-locking guide slideway 200 from the first arc transition slideway 400 or enters the self-locking guide slideway 200 from the hanging shaft mounting hole 100, the rotation direction needs to be changed once when the motion of one linear self-locking part is completed, so that the next linear self-locking part can enter; and the difficulty that the hanging shaft 4 enters the hanging shaft slideway or is separated from the hanging shaft slideway is increased once the rotating direction is changed. However, when the hanging scroll 4 enters the hanging scroll slideway, the hanging scroll 4 is easy to enter the hanging scroll slideway due to the guiding function of the self gravity, and when the hanging scroll 4 is separated from the hanging scroll slideway, the hanging scroll slideway can be separated only by overcoming the self gravity, so that the difficulty when the hanging scroll 4 is separated from the hanging scroll slideway is larger than that when the hanging scroll 4 enters the hanging scroll slideway, and the probability that the hanging scroll 4 is separated from the hanging scroll slideway can be reduced.
It should be noted that the number of the linear self-locking portions in the above embodiments may be determined according to actual needs. A self-locking guided skid 200 such as that shown in fig. 12 comprises a first linear self-locking portion 201, a second linear self-locking portion 202, and a third linear self-locking portion 203; the first and second linear self-locks 201, 202 communicate via a first arcuate self-lock 204, the second and third linear self-locks 202, 203 communicate via a second arcuate self-lock 205, and the third linear self-lock 203 communicates with the outlet of the guide inlet chute 300 via a first arcuate transition chute 400. The self-locking guide runner 200 shown in fig. 9-11 has only one linear self-locking portion and thus, an arcuate self-locking portion is not required.
In addition, the principle of the arc-shaped self-locking part for changing the rotation direction of the hanging shaft 4 is the same as the principle of the first arc-shaped transition slideway 400 for changing the rotation direction of the hanging shaft 4 in the above embodiment, and the description thereof is omitted.
Referring to fig. 9-12, the hanging-shaft mounting hole 100 in the above embodiment includes a linear connecting portion 101 and an arc bottom portion 102 disposed at one end of the linear connecting portion 101 to enable the hanging shaft 4 to enter the working state, and the linear connecting portion 101 is communicated with the arc bottom portion 102; one side of the linear connecting part 101 is provided with a mounting inlet for communicating with an outlet of the self-locking guide slideway 200; wherein the linear direction of the linear connecting part 101 is parallel to the gravity direction of the hanging shaft 4 (as shown in fig. 9, 10 and 12) or has an included angle (as shown in fig. 11).
Referring to fig. 9, 10 and 12, when the linear direction of the linear connecting portion 101 is parallel to the gravity direction of the hanging shaft 4, due to the moment the hanging shaft 4 enters the hanging shaft mounting hole 100 from the self-locking guide slideway 200, the hanging shaft 4 can enter the arc bottom 102 along the self-gravity direction thereof under the guiding action of the linear connecting portion 101 to enter a working state, and in the process, the hanging shaft 4 can directly fall into the arc bottom 102 only under the self-gravity action without rotating. When the hanging shaft 4 is separated from the hanging shaft mounting hole 100 to enter the self-locking guide slideway 200, the hanging shaft 4 needs to move upwards along the linear connecting part 101 to enter the self-locking guide slideway 200, and in the process, the gravity needs to be overcome to achieve the purpose. Referring to fig. 11, when the linear direction of the linear connecting portion 101 forms an included angle with the gravity direction of the hanging shaft 4, the hanging shaft 4 only needs to overcome the component force of gravity when moving along the linear connecting portion 101; therefore, when the linear direction of the linear connecting portion 101 is parallel to the gravity direction of the hanging shaft 4, the hanging shaft 4 is more difficult to enter the self-locking guide slideway 200 from the hanging shaft mounting hole 100 so as to seek to be separated from the hanging shaft slideway, thereby reducing the probability that the hanging shaft 4 is separated from the hanging shaft slideway and improving the reliability of the display device hung on a wall body.
In order to further improve the reliability of the display device hung on the wall, referring to fig. 9, the other end of the linear connecting portion 101 is provided with an arc top 103 integrated with the linear connecting portion 101; when the hanging shaft 4 tends to be pulled out of the hanging shaft mounting hole 100, the hanging shaft 4 can sequentially enter the linear connecting part 101 and the arc top part 103 from the arc bottom part 102 along one direction under the condition of no action of human force, and after the hanging shaft 4 enters the arc top part 103, the reaction force of the arc top part 103 enables the hanging shaft 4 to move to the mounting inlet of the linear connecting part 101 and enter the self-locking guide slideway 200; if the arc top 103 is not provided, the hanging shaft 4 can sequentially enter the linear connecting part 101 from the arc bottom 102 along one direction under the condition of no action of human force, and then directly enters the self-locking guide slideway 200 from the installation inlet of the linear connecting part 101; it can be seen that, in the present embodiment, the time for the hanging axle 4 to enter the self-locking guiding slideway 200 from the hanging axle mounting hole 100 is substantially prolonged by the other end of the linear connecting portion 101, and the probability for the hanging axle 4 to enter the self-locking guiding slideway 200 from the hanging axle mounting hole 100 is reduced.
Referring to fig. 11, in addition, in order to avoid that the hanging shaft 4 is easy to enter the self-locking guiding slideway 200 from the hanging shaft mounting hole 100 when the linear direction of the linear connecting portion 101 forms an included angle with the gravity direction of the hanging shaft 4, the mounting inlet and the outlet of the self-locking guiding slideway 200 can be communicated through a second arc-shaped transition slideway 500 capable of changing the rotation direction of the hanging shaft 4, so that the second arc-shaped transition slideway 500 can reduce the probability that the hanging shaft 4 enters the self-locking guiding slideway 200 from the hanging shaft mounting hole 100 when the original rotation direction of the hanging shaft is changed.
It should be noted that, when the hanging scroll slideway is in the structure shown in fig. 9, the hanging scroll 4 is in the working state, please refer to fig. 14, the hanging scroll 4 receives the upward supporting force from the lower part of the arc bottom 102, the rightward thrust from the left side wall of the arc bottom 102 to the hanging scroll 4, and the leftward thrust from the right side wall of the arc bottom 102 to the hanging scroll 4, so as to ensure that the hanging scroll 4 can be stably located at the arc bottom 102, and hang the display device on the wall. When the hanging shaft 4 is separated from the hanging shaft mounting hole 100 and enters the self-locking guide slideway 200, a force needs to be applied to the hanging shaft 4, and the direction of the force is the same as the direction of the force generated by the left side wall of the arc bottom 102 to the right side of the hanging shaft 4 and the force generated by the lower part of the arc bottom 102 to the upward supporting force of the hanging shaft 4.
