Description

Technical Field

[0001] The utility model relates to the technical field of anti-shake and abnormal noise functional parts, in particular to a universal ball bearing support structure. Background Art

[0002] In the prior art, some functional parts that need to rotate may shake or make abnormal noises during rotation, such as between the exterior rearview mirror body and the mirror body support, where the mirror body needs to rotate along the support; or between a display screen that needs to rotate and a display screen mounting bracket. In the above cases, the functional parts will be more or less affected by external factors during rotation, resulting in shaking or abnormal noises.

[0003] For example, the exterior rearview mirror body bracket is generally connected to the exterior rearview mirror support 4 only through the rotating shaft 5 and the compression spring assembly. Due to the manufacturing deviation of the rearview mirror body bracket 7, the exterior rearview mirror support 4 and the rotating shaft 5, as well as the influence of the weight of the exterior rearview mirror body and the pressure of the compression spring 6, it is easy to make the outer edge gap of the matching structure of the rearview mirror body bracket 7 and the exterior rearview mirror support 4 uneven, and cause the vehicle to vibrate and make abnormal noises when driving on bumpy roads, and vibrate and make abnormal noises when closing the door; such jitter and abnormal noise need to be solved in the trial production process by adjusting the matching accuracy of the rearview mirror body bracket and the exterior rearview mirror support and the rotating shaft, increasing the pressure of the compression spring, adding a soft rubber structure and other measures, and it is necessary to adjust the mold and other tooling, and the problem rectification cycle is long, which affects the listing progress and appearance quality of the new model;

[0004] The existing patent technology with patent announcement number CN216034087U discloses an anti-shake and abnormal noise structure for an exterior rearview mirror, which specifically discloses "comprising a rearview mirror housing, a folder and a support for fixing on a vehicle door; an arc-shaped card slot is arranged on the upper end surface of the support and on one side close to the rearview mirror housing; the card slot is arranged around the folder; a ball is arranged in the card slot; the top of the ball is against the rearview mirror housing, and the present application arranges a ball between the support and the rearview mirror housing, and the ball can support the rearview mirror housing The function is to ensure that the gap between the rearview mirror housing and the support will not change due to the failure of the folder, thereby solving the problem of abnormal folding noise, and can make the rearview mirror structure more stable and improve the rearview mirror mode to reduce the shaking of the rearview mirror housing. Although the above technology sets a ball between the support and the rearview mirror housing, the ball must be attached to the rearview mirror housing for use, and it cannot be disassembled and removed to be applied to other functional parts that need to be rotated, so the versatility is poor. At the same time, a separate arc groove needs to be opened on the rearview mirror housing, which increases the workload.

[0005] For another example, in electronic products that need to rotate, such as a rotating electronic screen in a car, when it rotates, the bumps of the car or the forceful opening and closing of the door can also cause the display screen to shake and make unusual noises.

[0006] In summary, most of the existing structures are designed to prevent shaking or abnormal noise in specific environments. Such structures have limitations and can only be used in a single scenario. They are generally not disassembled and need to be used with corresponding functional parts. Therefore, they are less versatile and cannot be used independently. In order to solve the above shortcomings, this application proposes a universal and independent ball structure that can be used in functional parts that need to rotate in multiple scenarios to prevent shaking and abnormal noise. Utility Model Content

[0007] The technical problem to be solved by the utility model is: how to provide a universal independent structure which can be installed on a number of functional parts that need to be rotated and is used to prevent shaking and abnormal noise.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0009] A universal ball support structure, comprising:

[0010] The ball bearing body has a semi-enclosed ball cavity inside and an opening at the top;

[0011] A ball is rolled in the ball cavity, the diameter of which is larger than the inner diameter of the top opening of the ball cavity, and the top of the ball extends out of the ball support body;

[0012] The bottom of the ball bearing body is symmetrically provided with two groups of positioning structures for positioning, and corresponding clamping parts are provided below the two groups of positioning structures.

[0013] The utility model uses a ball bearing body, and a rollable ball is arranged in the ball bearing body, and a positioning structure and a clamping piece that can be positioned are arranged at the bottom of the ball bearing body. The application has a simple structure and strong versatility. The design of the ball and the ball bearing can prevent the structure to be installed from shaking and making abnormal noises. It can be used between the rearview mirror support and the rearview mirror body bracket of the automobile, or on other functional parts that need to be rotated, or on other equipment, and can prevent shaking and making abnormal noises during the driving of the automobile.

[0014] As a further solution of the utility model: it also includes an elastic washer, which is installed at the bottom of the ball bearing body and between the positioning structure and the clamping piece.

[0015] As a further solution of the utility model: the bottom of the clamping piece is in a conical structure, and an installation gap is left between the clamping piece and the elastic gasket.

[0016] As a further solution of the utility model: the elastic gasket is made of rubber.

[0017] As a further solution of the utility model: a rolling gap of 0.1 mm is left between the ball bearing body and the ball, and grease is applied between the ball bearing body and the ball.

[0018] As a further solution of the utility model: vertical downward grooves are provided on both sides of the top of the ball bearing body.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] Firstly, the utility model adopts a ball bearing body, and a rollable ball is arranged in the ball bearing body, and a positioning structure and a clamping piece capable of "Z" direction positioning are arranged at the bottom of the ball bearing body. The utility model has a simple structure, an independent design, and is not dependent on the design of functional parts. It is easy to install and disassemble. It only needs to open a mounting hole at the corresponding position of the functional part, and it can be directly installed. It has strong versatility and can be applied to functional parts that need to rotate and have shaking or abnormal noise in multiple fields. It has a wide range of adaptability. The cooperation of the ball and the ball bearing can prevent the installed functional parts from shaking and making abnormal noises.

[0021] Secondly, the utility model adopts a universal ball structure to support the exterior rearview mirror body bracket;

[0022] First, it can effectively solve the shaking and abnormal noise caused by the exterior rearview mirror body bracket being connected only by the rotating shaft and the compression spring assembly;

[0023] Second, it effectively solves the problem of uneven outer edge gap between the rearview mirror body bracket and the exterior rearview mirror support structure. Even if the folder positioning structure fails, it does not affect the gap between the rearview mirror body and the support.

[0024] Third, it can make the rearview mirror structure more stable and improve the rearview mirror modality;

[0025] Fourth, the rotation resistance of the exterior rearview mirror body is made smaller, thereby reducing the motor load of the folder and improving the durability of the folder;

[0026] Finally, the ball structure of the utility model is a universal independent structure, which can be installed on other functional parts that need to be rotated, such as a display screen that can rotate left and right, or a rotating glass turntable on a dining table, etc. These functional parts will produce more or less abnormal noise and vibration during the rotation process. The ball structure of the present application can be applied to the above-mentioned functional parts to reduce the abnormal noise and vibration generated by the rotation, and is used to prevent shaking and abnormal noise.

[0027] The structure of the present application also has a rubber elastic gasket. The function of the rubber elastic gasket is to keep the universal ball structure in close contact with the exterior rearview mirror body bracket (it can also be other installed functional parts) at all times to prevent abnormal noise caused by a gap between the ball and the exterior rearview mirror body bracket. Even if the folder spring fails, it can still effectively prevent abnormal noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] Example 1

[0046] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A universal ball support structure includes a ball support body 1 and a ball 2, wherein the ball support body 1 is open at the top and closed at the bottom, and a ball cavity is provided inside the ball support body 1 for mounting the ball 2, and a rolling gap is left between the ball support body 1 and the ball 2, and the rolling gap size is preferably 0.1 mm, so that the ball 2 can rotate in the ball cavity, and grease is applied between the ball support body 1 and the ball 2 to reduce the rolling resistance of the ball 2 in the ball cavity;

[0047] Furthermore, the inner diameter of the top opening of the ball bearing body 1 is smaller than the diameter of the ball 2. Such a design can prevent the ball 2 located in the ball bearing body 1 from slipping out of the ball cavity, while the top of the ball 2 can protrude out of the ball cavity, which is equivalent to the ball cavity adopting a semi-closed spherical cavity. It should also be noted that the top opening of the ball bearing body 1 is planar, and vertical downward grooves are provided on both sides of the top opening of the ball bearing body 1.

[0048] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, positioning structures 111 for limiting the ball structure in the "Z" axis direction are installed on both sides of the bottom of the ball bearing body 1, wherein the two positioning structures 111 are arc-shaped structures, and are integrally formed with the ball bearing body 1, wherein a clamping member 112 is also installed at the bottom of the two positioning structures 111, and the bottom of the clamping member 112 is a cone-shaped structure, and a certain gap is left between the clamping member 112 and the positioning structure 111, which is used to install subsequent functional parts, such as a rearview mirror support for automobiles, or a display screen support;

[0049] It should be noted that an inverted "U"-shaped buffer groove is provided between the two clips 112. When the clips 112 are clipped to the functional part, they will deform. The design here is to leave a buffer space for the deformation, so that the clips 112 can be smoothly clipped into the exterior rearview mirror support.

[0050] Furthermore, an elastic gasket 3 is sleeved below the positioning structure 111 and on the outside of the clamping member 112. The elastic gasket 3 is made of rubber. Taking the application of the present invention to the exterior rearview mirror body as an example, the rubber elastic gasket 3 of the present invention is used to keep the universal ball structure in close contact with the exterior rearview mirror body bracket 7 at all times (refer to Figure 7 ) to prevent the ball structure from making abnormal noises with the exterior rearview mirror body bracket 7, thereby preventing the exterior rearview mirror body bracket 7 from shaking when driving on bumpy roads and closing the door, and preventing abnormal noises from being generated between the ball structure and the exterior rearview mirror support 4.

[0051] It should be noted that the specific dimensions of the spacing between the two clips 112 and the diameters of the outer rings of the two clips 112 of the present application need to be determined according to the functional parts to be installed in the ball structure of the present application. The conical shape of the bottom of the clips 112 of the present application is also designed to accommodate the installation of the corresponding functional parts.

[0052] Example 2

[0053] Reference Figure 6 , Fig. 9 , Fig.10 and Fig.11 The automobile exterior rearview mirror body includes the ball structure in Example 1, that is, the ball structure in Example 1 is applied to the automobile exterior rearview mirror body, which can effectively solve the shaking and abnormal noise caused by the exterior rearview mirror body bracket 7 being connected only by the rotating shaft 5 and the compression spring 6; it can also solve the problem of uneven outer edge gap between the exterior rearview mirror body bracket 7 and the exterior rearview mirror support 4. Even if the folder positioning structure fails, it does not affect the gap between the rearview mirror body and the support; it can make the rearview mirror structure more stable and improve the rearview mirror mode; make the rotation resistance of the exterior rearview mirror body smaller, thereby reducing the motor load of the folder and improving the durability of the folder.

[0054] The exterior rearview mirror body of the automobile further includes an exterior rearview mirror support 4, a rotating shaft 5, a compression spring assembly, an exterior rearview mirror body bracket 7, a guide rail 8, a structural adhesive 9 and a dustproof sealing pad 10, wherein the ball structure in Embodiment 1 is installed on the exterior rearview mirror support 4. Specifically, when the exterior rearview mirror support 4 is connected and installed with the exterior rearview mirror body bracket 7, it is only through the cooperation of the rotating shaft 5 and the compression spring assembly. The rotating shaft 5 is located at the middle position of the exterior rearview mirror support 4. The compression spring assembly includes a compression spring 6, which is sleeved on the outside of the rotating shaft 5. When the exterior rearview mirror support 4 is connected with the exterior rearview mirror body bracket 7, the rotating shaft 5 needs to be connected with the exterior rearview mirror body bracket 7.

[0055] Since the exterior mirror body bracket 7 is generally connected to the exterior mirror support 4 only through the shaft 5 and the compression spring assembly, the manufacturing deviation of the exterior mirror body bracket 7, the exterior mirror support 4 and the shaft 5, as well as the influence of the weight of the exterior mirror body and the pressure of the compression spring 6, it is easy to make the outer edge gap of the matching structure of the exterior mirror body bracket 7 and the exterior mirror support 4 uneven, and cause the vehicle to shake and make abnormal noises when driving on bumpy roads, and to shake and make abnormal noises when closing the door. For this reason, the present application sets three groups of ball structures and installs them equidistantly at the outer edge of the exterior mirror support 4. It should be noted here that the number of ball structures needs to be determined according to the actual situation. The present application does not limit it, and only provides one of the implementation methods for reference;

[0056] Reference Figure 7 and Fig.10 In this application, a mounting groove is provided at a corresponding position on the outer edge of the exterior rearview mirror support 4, and the ball support body 1 can be inserted into the mounting groove. The mounting gap between the corresponding positioning structure 111 and the clamping member 112 is just enough to clamp the upper and lower sides of the bottom plate of the main mounting groove (refer to Figure 7 ), at this time, the elastic gasket 3 is actually made of rubber material between the elastic gasket 3 and the positioning structure 111 and the bottom plate of the mounting groove body. The function of the rubber elastic gasket 3 is to keep the universal ball structure in close contact with the exterior rearview mirror body bracket at all times to prevent the ball structure and the exterior rearview mirror body bracket from making abnormal noises, thereby preventing the exterior rearview mirror body bracket 7 from shaking when driving on bumpy roads and closing the door, and making abnormal noises with the exterior rearview mirror support 4.

[0057] Furthermore, it is connected with the exterior rearview mirror support 4 through two "Z"-direction positioning structures 111 and two clamping parts 112, a total of three places (evenly distributed or fine-tuned according to the specific structural data of the exterior rearview mirror and the folding stroke), and the three ball structures provide auxiliary support for the exterior rearview mirror body bracket 7; and a guide rail 8 is opened at the corresponding position on the exterior rearview mirror body bracket 7, and one end of the ball 2 installed on the exterior rearview mirror support 4 can be rollingly connected to the guide rail 8, and the ball 2 and the guide rail 8 can be in line contact, which can reduce the rolling resistance of the ball, and the guide rail 8 and the exterior rearview mirror body bracket 7 are fixed by structural adhesive 9.

[0058] Furthermore, this example is also designed with a dustproof sealing gasket 10, which is located between the exterior rearview mirror support 4 and the exterior rearview mirror body bracket 7 and on the outside of the ball bearing body 1, and can prevent external dust and other foreign matter from entering the ball bearing body 1 to affect the rolling performance of the ball structure.

[0059] Example 3

[0060] Different from the second embodiment, the ball bearing structure in the first embodiment can also be applied to a display screen that needs to be rotated on a car or other electronic products (see Fig.12 , Fig.12 It is only a schematic diagram). Similarly, when the display screen 12 rotates about the central axis relative to the display screen mounting bracket 11, abnormal noise and shaking may occur. A plurality of ball structures of the present application are provided and equidistantly installed in the holes on the display screen mounting bracket 11. The installation method is consistent with the installation method of the ball structure in Example 2 installed in the exterior rearview mirror support 4, and the present application will not be repeated here. The ball 2 in the ball structure forms a line contact with the display screen, and there is no need to specially design a guide groove on the display screen 12 to accommodate the ball 2, thereby increasing the workload. This can reduce the rolling resistance of the ball 2. Applying the present application here can prevent the display screen 12 from shaking and making abnormal noises when the vehicle is driving on bumpy roads or closing the door. The present application can be applied not only to the automotive field, but also to functional parts that need to rotate in other fields.

[0061] Example 4

[0062] Unlike Examples 2 and 3, the ball structure in Example 1 can also be applied to a glass turntable for a dining table and can be installed equidistantly on the outer edge of the glass turntable. The ball structure of the present application can be slightly adjusted according to different application scenarios, that is, the clip 112 at the bottom of the ball support body 1 can be designed into the shape of the clip 112 if the functional part to be installed is convenient for opening a hole. If the functional part to be installed is not convenient for opening a hole, the bottom can be designed to be bolted or a suction cup or other suitable installation methods.

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
