Description

Technical Field

[0001] The utility model relates to the technical field of electronic product brackets, in particular to a bracket for an electronic display device. Background Art

[0002] At present, electronic products and equipment are widely used in various fields, such as laptops, tablet computers and other electronic devices.

[0003] Because of their small size, light weight and good portability, they are loved by people. With the development of technology, electronic devices such as laptops and tablets have become indispensable electronic products in people's lives. However, in the process of work and study, due to the limitations of the work and study venues, laptops, tablets and other electronic devices usually need to be supported by stands.

[0004] There are many liftable bracket structures on the market to support electronic devices such as laptops and tablets, which use one-way bearings to generate damping force in a specified direction, such as Chinese patent CN212584582U. However, in order to reduce costs, the one-way bearings used in this type of product are relatively low in price, and their corresponding processing accuracy is also relatively low. The bearing seats of this type of product are usually special-shaped parts, which are usually manufactured by casting methods, and their processing accuracy is also not high. When assembling the one-way bearing in the bearing seat, it is either too tight or too loose. If it is too tight, it is easy to cause damage to the one-way bearing, and if it is too loose, it cannot generate damping force. Especially for aluminum bearing seats with low mechanical strength, the two are difficult to adapt. Even if the adaptability is good during assembly, it is very easy to wear and slip after a period of use, resulting in the product being unable to continue to be used, resulting in low consumer satisfaction with this type of product and a high customer complaint rate. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a bracket for an electronic display device, and the utility model adopts the following technical solutions:

[0006] A bracket for an electronic display device, comprising a first component, a second component and a one-way damping device, wherein the one-way damping device is arranged between the first component and the second component, and the first component is combined with at least one bearing seat; the one-way damping device comprises:

[0007] a one-way bearing capable of applying a damping force in its damped state to hinder the rotation of the second member relative to the first member;

[0008] a damping shaft fixedly connected to the inner hole of the one-way bearing, wherein the damping shaft rotates in response to the driving of the second member; and

[0009] The bearing protection sleeve is firmly fixed to the positioning hole formed in the bearing seat, and the outer peripheral surface of the one-way bearing is fixed to the bearing protection sleeve to avoid unexpected wear between the outer peripheral surface of the one-way bearing and the bearing seat in the damping state.

[0010] Furthermore, the bearing seat is a metal seat or a plastic seat, and the metal seat can be a bearing seat, a cast iron seat or a steel seat.

[0011] Further, the bearing seat is constructed as a part of the first component that is integral with or separable from the first component.

[0012] Furthermore, a rotation limiting structure is provided between the bearing protection sleeve and the bearing seat, and the rotation limiting structure is configured to limit the circumferential rotation of the bearing protection sleeve relative to the bearing seat.

[0013] Furthermore, the rotation limiting structure includes a convex portion and a concave portion that fit each other, and the convex portion and the concave portion are selectively arranged on the bearing protection sleeve and the bearing seat respectively.

[0014] Furthermore, the rotation limiting structure includes an axial groove arranged on the outer side wall of the bearing protection sleeve and a convex rib arranged on the inner side wall of the bearing seat and cooperating therewith.

[0015] Furthermore, the bearing protection sleeve is a steel component or a wear-resistant plastic component.

[0016] Furthermore, the bearing protection sleeve and the bearing sleeve have different strengths.

[0017] Furthermore, the one-way bearing is inserted into the bearing protection sleeve in an interference fit manner.

[0018] Further, the one-way damping device is configured to generate a damping force only during the folding process of the first component relative to the second component, and to freely rotate during the unfolding process of the first component relative to the second component.

[0019] Furthermore, a bidirectional damping device is arranged between the first component and the second component, and the bidirectional damping device is arranged to generate a damping force both in the folding process and in the unfolding process.

[0020] Furthermore, the damping force generated by the bidirectional damping device during the folding process is much smaller than the damping force generated by the unidirectional damping device during the folding process, and the damping force generated during the unfolding process is greater than the damping force generated by the unidirectional damping device during the folding process.

[0021] Furthermore, the bidirectional damping device is configured as a jacket with an opening, and when the jacket is embedded in the bearing seat, the opening is reduced to clamp the damping shaft to generate a damping force.

[0022] Furthermore, the bearing sleeve is inserted into the bearing protection sleeve in an interference fit manner.

[0023] Further, the first member is configured as a base suitable for being placed on a table, and the second member is configured as a swing arm capable of pivoting relative to the base; or,

[0024] The first member is configured as a support plate suitable for placing the electronic display device, and the second member is configured as a swing arm capable of pivoting relative to the support plate.

[0025] The bearing protection sleeve is fixedly connected to the one-way bearing via a transition sleeve, so as to facilitate the processing and installation of the bearing protection sleeve.

[0026] Compared with the prior art, the utility model has the following advantages:

[0027] (1) The utility model fixes the one-way bearing in the bearing seat by means of a bearing protection sleeve. Since the bearing protection sleeve can be manufactured separately, a rotation limiting structure (such as a clamping structure) can be provided between the bearing protection sleeve and the bearing seat, or a larger interference fit can be provided between the two, so that the bearing protection sleeve can be more firmly fixed in the bearing seat (which can be an aluminum seat, a metal seat or a plastic seat). Since the one-way bearing manufactured separately has a higher processing accuracy, it can be better matched with the one-way bearing to avoid slipping between the two. Therefore, the utility model avoids unexpected wear and slipping due to direct contact between the outer peripheral surface of the one-way bearing and the bearing seat, especially the aluminum bearing seat, by providing a bearing protection sleeve that can be firmly fixed in the positioning hole. At the same time, the use of the bearing protection sleeve in the utility model can also reduce the difficulty of assembly and matching between the one-way bearing and the one-way bearing.

[0028] (2) A bidirectional damping device is disposed between the first component and the second component of the utility model, and is configured to generate a damping force during the folding process that is much smaller than the damping force generated by the unidirectional damping device during the folding process, and to generate a damping force during the unfolding process that is larger than the damping force generated by the unidirectional damping device during the folding process, so as to prevent the unfolding angle from being too large due to lack of resistance and causing over-position (crossing the designated position) during the unfolding process. At the same time, during use, the bidirectional damping device will generate a large friction force to support the unfolded bracket to prevent the bracket from slipping due to insufficient support force.

[0029] (3) The bearing protection sleeve of the utility model can be fixedly connected to the one-way bearing by means of a transition sleeve, which can further improve the assembly accuracy of the one-way bearing, thereby facilitating the processing and installation of the bearing protection sleeve.

[0042] Embodiment 1:

[0043] like Figure 1 , 2 As shown, the utility model discloses a bracket for an electronic display device, and the electronic display device in the utility model can be an electronic product such as a tablet computer, a mobile phone or a laptop computer. The bracket includes a first component 1, a second component 2 and a support plate 5, the second component 2 and the first component 1 are pivotally connected to adjust the angle between the two, and the support plate 5 and the second component 2 are pivotally connected to adjust the angle between the two. The first component 1 is configured as a base suitable for being placed on a table, and the base includes a seat plate 11. The first component 1 is combined with a bearing seat. In this embodiment, the bearing seat is a bearing seat 12. In other embodiments, the bearing seat can be a metal material with high strength such as a cast iron seat or a steel seat. In other embodiments, the "seat" outside the bearing protection sleeve fixed to the metal material can also be selected from a wear-resistant plastic material. The two constitute a traditional "plastic-coated steel" structure, which can also achieve the technical effect of avoiding unexpected wear between the outer peripheral surface of the one-way bearing 32 and the aluminum seat in the damping state. In other embodiments, the first component can also be combined with multiple bearing seats 12, and at this time, the multiple bearing seats 12 are usually arranged at intervals. The second component 2 is configured as a swing arm that can pivot relative to the base, and the aluminum seat can achieve a rotational connection between the swing arm and the base 11.

[0044] A one-way damping device is provided between the first component 1 and the second component 2. Figure 3 As shown, the one-way damping device includes a one-way bearing 32, a damping shaft 31 and a bearing protection sleeve 33. Specifically, the one-way bearing 32 can apply a damping force that hinders the second member from rotating relative to the first member in its damping state. The damping shaft 31 is fixed to the inner hole of the one-way bearing, and the damping shaft rotates in response to the drive of the second member. The bearing protection sleeve is firmly fixed to the positioning hole formed in the aluminum seat, and the outer peripheral surface of the one-way bearing is fixed to the bearing protection sleeve to avoid unexpected wear between the outer peripheral surface of the one-way bearing and the aluminum seat in the damping state.

[0045] It should be noted that the so-called firmly fixed connection means that the bearing protection sleeve is fastened in the positioning hole of the aluminum seat, and no relative sliding occurs between the bearing protection sleeve and the aluminum seat due to external forces during normal use. Specifically, in order to achieve the purpose of firmly fixed connection, in this embodiment, not only is the bearing protection sleeve embedded in the positioning hole of the aluminum seat in an interference fit manner, but a rotation limiting structure is further provided to further limit the rotation of the bearing protection sleeve relative to the aluminum seat. The specific structure of the rotation limiting structure will be described in detail below.

[0046] The one-way bearing 32 is inserted in the bearing protection sleeve 33 with an interference fit. In this way, the one-way bearing 32 can be fixed in the bearing protection sleeve 33 to realize the assembly of the one-way bearing 32. In this embodiment, since there is a size error in the production of the bearing seat of the one-way bearing 32, the two cannot achieve perfect size matching during assembly. The one-way bearing 32 is inserted in the bearing protection sleeve 33 with an interference fit, which can reduce the wear probability between the one-way bearing 32 and the bearing protection sleeve, and avoid the phenomenon of slipping between the damping one-way bearing 32 and the bearing protection sleeve. In addition, the one-way damping device 3 only generates a damping force during the folding process of the first component 1 relative to the second component 2, and rotates freely during the unfolding process of the first component 1 relative to the second component 2, thereby realizing a stop at any position during the unfolding process.

[0047] The one-way bearing 32 in the present application can adopt the one-way bearing with a special-shaped roller in the outer ring in the prior art to achieve smooth rotation in one angular direction and rotation braking in another angular direction, which will not be described in detail here. The damping shaft 31 rotates in response to the drive of the second component. Specifically, the damping shaft is configured to rotate relative to the one-way bearing 32 during the unfolding process, and to prevent the one-way bearing from rotating relative to the one-way bearing during the folding process.

[0048] In this embodiment, when the support plate 5 needs to be raised, the one-way damping device rotates forward around the damping shaft. Therefore, when the support plate is raised, due to the one-way damping device, the damping of the bracket is minimal and approaches zero, so that the bracket can be supported with very little force. When the support plate 5 needs to be lowered, the one-way damping device is reversed and locked around the damping shaft 31. Therefore, when the support plate 4 is lowered, the damping is the damping of the rotation of the shaft itself, so that a very large force is required to close the bracket, so that when the object is placed on the support plate, the bracket can provide better support for the object, and the object is not easy to press down the bracket to cause the bracket to fall.

[0049] like Figure 4 , 6 As shown in Figures 7 and 8, a rotation limiting structure is provided between the bearing protection sleeve 33 and the bearing seat 12. The rotation limiting structure includes an axial groove provided on the outer wall of the bearing protection sleeve and a convex rib matched with the inner wall of the bearing seat. Due to the provision of the rotation limiting structure, a rotation limit can be formed between the bearing protection sleeve and the aluminum seat, thereby further limiting the bearing protection sleeve from rotating relative to the aluminum seat. The aluminum seat is a detachable part on the first component 1. It is fixedly connected to the base 11 or the support plate 5 by screws.

[0050] like Figure 5 As shown, a bidirectional damping device 4 is also arranged between the first component 1 and the second component 2. The damping force generated by the bidirectional damping device 4 during the folding process is much smaller than the damping force generated by the unidirectional damping device during the folding process, and the damping force generated during the unfolding process is greater than the damping force generated by the unidirectional damping device during the folding process. This prevents the problem of excessive rotation due to excessive unfolding angle during the unfolding process. At the same time, during use, the bidirectional damping device 4 will generate a large friction force to support the unfolded bracket to prevent the bracket from slipping due to insufficient supporting force. Specifically, the bidirectional damping device 4 includes a jacket with an opening, and the jacket can be made of rubber, metal or wear-resistant plastic to generate damping force during both the folding process and the unfolding process.

[0051] It should be noted that, in order to achieve synchronous rotation of the bidirectional damping device 4 and the unidirectional damping device 3, an axial groove 41a is also provided on the outer wall of the bidirectional damping device 4. When the jacket is embedded in the bearing seat 12, the opening is reduced to clamp the damping shaft 31 to generate damping force.

[0052] The bearing protection sleeve 33 is a steel component or a wear-resistant plastic component. In this embodiment, the bearing protection sleeve made of steel or wear-resistant plastic material is firmly fixed to the positioning hole formed in the aluminum seat to avoid unexpected wear between the outer peripheral surface of the one-way bearing 32 and the aluminum seat in the damping state, and the matching of the assembly accuracy between the aluminum seat and the one-way bearing 32 can be achieved.

[0053] As a preferred solution of this embodiment, a moving shaft and a fixed shaft may be provided between the one-way damping device disposed between the first member and the second member and the rotating arm in this embodiment, and the two-way damping device further includes a moving shaft jacket 42 disposed coaxially with the jacket in the moving shaft. The fixed shaft may adopt a fixed structure used in the prior art, which will not be described in detail herein.

[0054] like Figure 8 As shown, in order to facilitate the installation of the bearing protection sleeve and reduce the processing difficulty of the bearing protection sleeve 33, the bearing protection sleeve 33 can be fixed to the bearing seat by a transition sleeve 34. Since the one-way bearing 32 requires higher precision to match it during production and processing, the inner wall of the transition bearing can be of greater precision during production, while the outer wall that matches the bearing protection sleeve 33 does not need to be set with too high precision during production, thereby facilitating the installation of the bearing protection sleeve.

[0055] When the present invention is in use, after electronic products such as mobile phones, tablets, and laptops are placed on the support plate 6, the electronic products are supported by the one-way damping device. When the swing arm needs to be lifted to unfold the bracket, the one-way damping device can reduce the resistance encountered by the swing arm during the lifting action, thereby achieving smooth unfolding of the present invention. At the same time, the two-way damping device 4 can be used to apply friction to the rotating shaft to prevent over-rotation, thereby optimizing the user experience.

[0056] Embodiment 2:

[0057] The difference between this embodiment and the first embodiment is that, in this embodiment, in addition to the first component being combined with a bearing seat, a bearing seat is also combined between the second component and the support seat. The structure of the bearing seat is similar to the structure in the embodiment. The one-way bearing in the bearing seat is combined with the second component and fixed to the support plate 5 by screws. In this embodiment, the bearing seat 12 is constructed as a part on the first component that is integrated with it. Rotating the bearing seat can achieve relative rotation between the second component and the support seat.

[0058] The above are only preferred embodiments of the present invention. The protection scope of the present invention shall be based on the scope defined by the claims. Several improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall also be regarded as the protection scope of the present invention.
