[0031] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0032] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of particular examples in the following are described. Of course, they are only examples and are not intended to limit the present application. Furthermore, the present application can repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not indicate a relationship between the various embodiments and / or settings discussed.

[0033] For the purpose of description, spatial relative terms as shown in the drawings can be used to describe the relative position relationship or movement condition of one element or feature relative to another element or feature, such as "internal", "external", "inboard", "outboard", "under", "below", "on", "above", "front", "back", and the like. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement condition is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both the up and down positions. The device can be additionally oriented (rotated by 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0034] With the development of the liquid crystal display industry, the size of display devices (such as liquid crystal televisions) is getting larger and larger. The display device is a device that can output image or tactile information, and the liquid crystal television is one of the most common display devices, as shown in Figure 2 As shown, the liquid crystal television includes a rear shell 31 and a power board 32, and a plurality of heat-generating components are arranged on the power board 32. The heat-generating components generate a large amount of heat during operation, and the rear shell 31 is locally deformed by heat. The deformed rear shell 31 is easy to press the power board 32, which causes the power board 32 to fail.

[0035] Therefore, in the related art, as Figure 2As shown, the plastic support 33 is arranged between the power panel 32 and the rear shell 31 of the existing display device 3, and the power panel 32 is connected to the rear shell 31 through the plastic support 33. Figure 1 As shown, the plastic support 33 includes a support body 331, one end of the support body is provided with a groove 332 connected to the power panel 32 in a clamping manner, and the other end of the support body 331 is connected to the rear shell 31 in an abutting manner. In this technical solution, the plastic support 33 is abutted against the rear shell 31 to prevent the rear shell 31 from being deformed to press the power panel 32. However, when the liquid crystal television plays sound, the loudspeaker assembly on the rear shell 31 vibrates, the vibration is transmitted to the power panel 32 through the plastic support 33, and the machine vibration causes abnormal noise, which not only affects the service life of the display device, but also causes customer complaints.

[0036] In order to solve the technical problem that the plastic support used by the existing display device in the prior art is easy to cause abnormal noise due to machine vibration of the display device, which not only affects the service life of the display device, but also causes customer complaints, the application provides a kind of buffer support and display device, which can avoid the transmission of vibration energy from the second end of the body to the first end of the body, thereby preventing the power panel from vibrating and contacting other parts on the power panel side to produce abnormal noise, reducing the probability of falling or contact failure of components on the power panel, thereby ensuring the service life of the display device, and solving the problem of abnormal noise, avoiding user complaints.

[0037] Figure 3 And Figure 4 A kind of buffer support 1 provided by the embodiment of the application is arranged between the power panel 21 and the rear shell 22 of the display device 2, and the buffer support 1 includes an integrally formed rubber body 11, the body 11 has oppositely arranged first end 111 and second end 112, the first end 111 of the body 11 is connected to the power panel 21, and the second end 112 of the body 11 is connected to the rear shell 22 in an abutting manner;The body 11 is provided with a buffer cavity 113 along its own axis direction, the buffer cavity 113 extends from the second end 112 of the body 11 to the first end 111 of the body 11;Wherein, in the case that the second end 112 of the body 11 is subjected to external vibration, the buffer cavity 113 of the body 11 can absorb vibration energy to avoid the transmission of vibration energy to the power panel 21 installed at the first end 111 of the body 11.

[0038] It can be understood that the first end 111 of the body 11 is connected to the power panel 21, and specifically, the connection of the first end 111 of the body 11 to the power panel 21 includes a fixed connection mode, and can also include a clamping connection mode. For example, Figure 4As shown, the second end 112 of the body 11 is in abutting connection with the rear shell 22, so that at least a part of the body 11 is located between the power board 21 and the rear shell 22, and the body 11 separates the power board 21 and the rear shell 22. Even if the heat-generating components on the power board 21 generate a large amount of heat during operation, the second end 112 of the body 11 can abut against the side of the rear shell 22 facing the power board 21, thereby preventing the deformed rear shell 22 from being warped to press the power board 21, and ensuring the working reliability of the power board 21. In the case that the second end 112 of the body 11 is subjected to external vibration, for example, when the liquid crystal television plays sound, the speaker assembly on the rear shell 22 generates vibration, the buffer cavity 113 of the body 11 absorbs the external vibration energy, that is, the body 11 consumes most of the vibration energy, thereby preventing the vibration energy from being transmitted from the second end 112 of the body 11 to the first end 111 of the body 11, so as to prevent the power board 21 from vibrating to contact other parts of the power board 21 and generate abnormal sound, reduce the probability of dislodging or poor contact of components on the power board 21, and further ensure the service life of the display device 2, while solving the problem of abnormal sound and avoiding user complaints.

[0039] Since the body 11 is made of rubber material, the body 11 itself has a certain elasticity, and the body 11 itself can absorb a part of the vibration energy, thereby further preventing the vibration energy from being transmitted from the second end 112 of the body 11 to the power board 21, so as to reduce the probability of dislodging or poor contact of components on the power board 21, and further ensure the service life of the display device 2.

[0040] It should be noted that the body 11 can be provided as a cylindrical shape or a square cylindrical shape, and the shape of the body 11 does not constitute a limitation on the technical effects to be achieved by the present application. In order to facilitate manufacturing and use, the body 11 is provided as a cylindrical shape as a whole.

[0041] In addition, the buffer support 1 is arranged as much as possible at the position or periphery of the rear shell 22 which is easy to be deformed by heat, so as to ensure the working reliability of the power board 21. In one display device 2, the buffer support 1 can be provided with a plurality of buffer supports 1, and those skilled in the art can design the position distribution of the plurality of buffer supports 1 according to actual needs.

[0042] In some embodiments, the body 11 is provided with a through groove 12 in communication with the buffer cavity 113, and the through groove 12 is arranged along the radial direction of the body 11. It can be understood that, in the case that the second end 112 of the body 11 is subjected to external vibration, both the buffer cavity 113 and the through groove 12 can absorb the external vibration energy, and the through groove 12 improves the ability of the body 11 to elastically deform under stress, i.e., the body 11 consumes most of the vibration energy, avoids the transmission of vibration energy from the second end 112 of the body 11 to the first end 111 of the body 11, thereby preventing the power board 21 from vibrating and contacting other parts of the power board 21 to produce abnormal sound, further reducing the probability of the dislodgement or poor contact of the components on the power board 21, and further ensuring the service life of the display device 2. When the external vibration disappears, the body 11 can return to the initial state, thereby stably separating the power board 21 and the rear shell 22, and avoiding the rear shell 22 from pressing the power board 21.

[0043] The through groove 12 can be square, oval, rhombic, etc., which is not specifically limited herein. Of course, the through groove 12 can also extend from the second end 112 of the body 11 to the first end 111 of the body 11, thereby further improving the ability of the body 11 to elastically deform under stress.

[0044] Further, the through groove 12 is provided in plurality, and the plurality of through grooves 12 are annularly distributed with the buffer cavity 113 as the center. Specifically, the plurality of through grooves 12 are annularly and uniformly distributed with the buffer cavity 113 as the center, and in the case that the second end 112 of the body 11 is subjected to external vibration, the provision of the plurality of through grooves 12 can further improve the ability of the body 11 to elastically deform under stress, and also improve the uniformity of the elastic deformation of the buffer bracket 1, i.e., the body 11 consumes most of the vibration energy, avoids the transmission of vibration energy from the second end 112 of the body 11 to the first end 111 of the body 11, thereby preventing the power board 21 from vibrating and contacting other parts of the power board 21 to produce abnormal sound, further reducing the probability of the dislodgement or poor contact of the components on the power board 21, and further ensuring the service life of the display device 2.

[0045] In some embodiments, as shown in FIG. 2, the through groove 12 is arranged in the buffer cavity 113. Figure 3 and Figure 4As shown, the first end 111 of the body 11 is provided with a first boss 13, the first boss 13 is provided with a groove 131 along the outer circumferential side thereof, and the power board 21 is provided with a through hole 211 which is connected with the groove 131 in a clamping manner. During installation, the first end 111 of the body 11 penetrates through the through hole 211, i.e. the groove 131 of the first boss 13 is clamped on the through hole 211 of the power board 21, so that the connection between the body 11 and the power board 21 is achieved. The body 11 separates the power board 21 from the rear shell 22, so that even if a large amount of heat is generated by the heating element on the power board 21 during operation, the second end 112 of the body 11 can resist the side of the rear shell 22 which faces the power board 21, so as to prevent the warped rear shell 22 from pressing the power board 21 after being heated and deformed, and ensure the working reliability of the power board 21.

[0046] In some embodiments, as shown in Figure 5 As shown, the side of the first boss 13 which is away from the body 11 is provided with a wedge-shaped portion 132, and the cross section of the wedge-shaped portion 132 decreases in the direction away from the body 11. During the installation of the buffer support 1, the end of the wedge-shaped portion 132 with smaller cross section penetrates through the through hole 211 of the power board 21, so that the groove 131 of the first boss 13 is clamped on the through hole 211 of the power board 21. The wedge-shaped portion 132 plays a guiding role during installation, and facilitates the installation.

[0047] Further, as shown in Figure 5 The wedge-shaped portion 132 is provided with a guiding surface 1321 which extends along the axial direction of the body 11. By providing the guiding surface 1321, the end of the wedge-shaped portion 132 with larger cross section can also relatively easily penetrate through the through hole 211 of the power board 21, so as to improve the installation convenience of the buffer support 1.

[0048] In some embodiments, the second end 112 of the body 11 is provided with a second boss 14, and the side of the second boss 14 which is away from the body 11 is provided with a protruding point 141 which is connected with the rear shell 22 in an abutting manner. In the initial state after the buffer support 1 and the power board 21 are installed, the protruding point 141 is connected with the rear shell 22 in an abutting manner, i.e. the side of the second boss 14 which is away from the body 11 does not directly contact with the rear shell 22, so as to reduce the contact area between the body 11 and the rear shell 22, reduce the transmission path of the external vibration energy from the second end 112 of the body 11 to the first end 111 of the body 11, and thus facilitate preventing the power board 21 from vibrating and contacting with other parts on the circumferential side of the power board 21 to produce abnormal sound, reduce the probability of the components on the power board 21 falling off or contacting abnormally, and further ensure the service life of the display device 2.

[0049] Further, the convex points 141 are provided in plurality, and the plurality of convex points 141 are uniformly distributed on the side of the second boss 14 away from the body 11. The plurality of convex points 141 being uniformly distributed on the side of the second boss 14 away from the body 11 means that the plurality of convex points 141 are arranged in a rectangular array on the side of the second boss 14 away from the body 11. By providing the plurality of convex points 141, it is possible to prevent the power board 21 from vibrating and contacting other parts on the periphery of the power board 21 to produce abnormal sound, reduce the probability of dislodging or poor contact of components on the power board 21, and further ensure the service life of the display device 2. Alternatively, the plurality of convex points 141 are arranged in a circular array on the side of the second boss 14 away from the body 11. By providing the plurality of convex points 141, it is possible to prevent the power board 21 from vibrating and contacting other parts on the periphery of the power board 21 to produce abnormal sound, reduce the probability of dislodging or poor contact of components on the power board 21, and further ensure the service life of the display device 2.

[0050] The convex points 141 can be provided in a spherical shape, a semi-spherical shape, an oval spherical shape, etc. In one example, the convex points 141 are provided in a semi-spherical shape. The convex points 141 have a spherical surface, and the spherical surface of the convex points 141 is in abutting connection with the side of the rear shell 22 facing the power board 21. This can minimize the contact area between the second boss 14 and the power board 21, and prevent the power board 21 from vibrating and contacting other parts on the periphery of the power board 21 to produce abnormal sound, reduce the probability of dislodging or poor contact of components on the power board 21, and further ensure the service life of the display device 2.

[0051] As shown in FIG. 1, Figure 4 The present application provides a display device 2, which includes a power board 21, a rear shell 22, and a buffer support 1 as described above, and the buffer support 1 is arranged between the power board 21 and the rear shell 22.

[0052] It can be understood that the first end 111 of the body 11 is connected with the power board 21, and the second end 112 of the body 11 is connected with the rear shell 22 in abutment, so that at least a part of the body 11 is located between the power board 21 and the rear shell 22, and the body 11 separates the power board 21 from the rear shell 22, that is, even if the heat generating component on the power board 21 generates a large amount of heat during operation, the second end 112 of the body 11 can abut against the side of the rear shell 22 facing the power board 21, thereby preventing the deformed rear shell 22 from being warped to press the power board 21, and ensuring the working reliability of the power board 21. In the case that the second end 112 of the body 11 is subjected to external vibration, for example, when the loudspeaker assembly on the rear shell 22 vibrates during the liquid crystal television playing sound, the buffer cavity 113 of the body 11 absorbs the external vibration energy, that is, the body 11 consumes most of the vibration energy, thereby preventing the vibration energy from being transmitted from the second end 112 of the body 11 to the first end 111 of the body 11, so as to prevent the power board 21 from vibrating to contact other parts of the power board 21 and generate abnormal sound, reduce the probability of the components on the power board 21 falling off or being in poor contact, and further ensure the service life of the display device 2, while solving the problem of abnormal sound and avoiding user complaints.
