Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to connection structures, interior rearview mirror assemblies, and vehicles. Background Technology

[0002] An interior rearview mirror is a device installed inside the passenger compartment of a vehicle to allow drivers and passengers to observe the road conditions behind the vehicle and the situation of rear passengers.

[0003] In the prior art, the interior rearview mirror includes a ball joint seat mechanism and a ball joint mechanism. The ball joint seat mechanism includes a housing and a ball joint seat disposed inside the housing, with a groove provided at the ball joint seat. The ball joint mechanism includes a ball joint, a ball joint connecting rod, and a base connected in sequence. The ball joint and the groove are fitted with a clearance fit through molding, allowing the ball joint mechanism and the ball joint seat to be rotatably connected.

[0004] However, if the rearview mirror is rotated to its limit and force is continued to be applied or if the rearview mirror is impacted, the ball joint mechanism may come out of the groove, rendering the rearview mirror unusable and affecting the user experience. Utility Model Content

[0005] One objective of this invention is to provide a connecting structure to solve the problem that the ball joint of the interior rearview mirror easily detaches from the groove of the ball joint seat. A second objective of this invention is to provide an interior rearview mirror assembly. A third objective of this invention is to provide a vehicle.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] In a first aspect, embodiments of this application provide a connection structure for a vehicle's interior rearview mirror assembly. The connection structure includes a support, a connecting bracket, and a limiting member. The support includes a limiting surface and a bottom surface facing each other, and the support has a mounting hole recessed from the limiting surface toward the bottom surface. The connecting bracket includes a connecting rod and a ball joint connected to the connecting rod. The ball joint is rotatably connected to the mounting hole and can rotate relative to the support to its limit position. The limiting member is connected to the connecting rod and is located on the side of the ball joint facing away from the bottom surface. When the ball joint is in its limit position, the limiting member contacts the limiting surface, and the connecting rod does not contact the support.

[0008] According to the aforementioned technical means, the ball joint can rotate in any direction within the mounting hole. This allows for adjustment of the rearview mirror assembly's angle through relative rotation between the ball joint and the support, enabling drivers and passengers to adjust the angle as needed. When the ball joint rotates to its limit relative to the support, a limiting component contacts the limiting surface of the support, while the connecting rod does not contact the support. This limits the rotation range of the ball joint relative to the support, preventing excessive rotation and dislodging the ball joint from the mounting hole. This ensures the normal operation of the rearview mirror assembly and improves its user experience.

[0009] In some embodiments, the limiting member includes a limiting protrusion protruding from the connecting rod in a first direction, the first direction being perpendicular to the extension direction of the connecting rod.

[0010] According to the above technical means, by setting a limiting protrusion on the connecting rod, the ball head can be restricted to avoid excessive rotation of the ball head relative to the support. It also facilitates the processing of the connecting rod and the limiting component. Moreover, the structure of the connecting rod and the limiting component is relatively simple, which simplifies the structure of the connection.

[0011] In some embodiments, the limiting protrusion surrounds the connecting rod.

[0012] Based on the aforementioned technical means, regardless of which direction the ball head rotates relative to the support to its limit position, the limiting protrusion can restrict the ball head to avoid excessive rotation relative to the support, thereby better preventing the ball head from coming out of the mounting hole.

[0013] In some embodiments, there are multiple limiting protrusions, which are spaced apart around the connecting rod.

[0014] Based on the aforementioned technical means, multiple limiting protrusions can also restrict the ball head from different directions to prevent excessive rotation of the ball head relative to the support, thereby preventing the ball head from coming out of the mounting hole. This also saves materials and reduces costs.

[0015] In some embodiments, the surface of the ball head includes a first plane and a second plane opposite to each other, and a spherical surface connecting the first plane and the second plane; the first plane is located on the side of the second plane facing away from the bottom surface, and the connecting rod is connected to the first plane.

[0016] According to the above technical means, compared with the ball head being a complete spherical structure, by setting the surface of the ball head as a first plane, a second plane, and a spherical surface, the volume of the ball head can be reduced, thereby reducing the volume of the mounting hole and allowing the mounting hole to better accommodate the ball head, so as to further reduce the risk of the ball head coming out of the mounting hole.

[0017] In some embodiments, the limiting member is spaced apart from the first plane.

[0018] According to the above technical means, there is a certain distance between the limiting member and the first plane. Compared with the limiting member contacting the first plane, when the ball head rotates to the limit position relative to the support, the rotation amplitude of the ball head is larger. This can prevent the limiting member from restricting the ball head from coming out of the mounting hole, and can avoid the limiting member restricting the ball head from rotating too little relative to the support, thus affecting the adjustment range of the mirror body.

[0019] In some embodiments, the mounting hole includes a straight hole portion and a spherical hole portion, the straight hole portion being located on the side of the spherical hole portion facing away from the bottom surface, and at least a portion of the spherical surface being located within the spherical hole portion.

[0020] According to the above technical means, if the ball head comes out of the spherical hole, it needs to go through the straight hole to completely come out of the mounting hole. Therefore, the ball head can be better restricted in the spherical hole by the cooperation of the straight hole and the spherical hole, so as to further reduce the risk of the ball head coming out of the mounting hole.

[0021] In some embodiments, the inner circumferential surface of the straight hole is a tapered surface, and the radial dimension of the end of the tapered surface facing away from the bottom surface is greater than the radial dimension of the end of the tapered surface facing the bottom surface.

[0022] Based on the above technical means, the restriction on the ball head or connecting rod by the straight hole can be reduced, thereby ensuring the rotation range of the ball head relative to the support and thus ensuring the adjustment range of the mirror body. Furthermore, in conjunction with the limiting component, the adjustment range of the mirror body can be ensured while preventing the ball head from dislodging from the mounting hole.

[0023] Secondly, embodiments of this application also provide an interior rearview mirror assembly, which includes the connecting structure and mirror body described in the first aspect above, wherein the connecting structure is fabricated and connected to the mirror body.

[0024] Since the rearview mirror assembly provided in this application includes the connection structure in the first aspect, it can solve the same technical problems as the connection structure described above and achieve the same technical effects, so it will not be described again here.

[0025] Thirdly, embodiments of this application also provide a vehicle that includes the interior rearview mirror assembly described in the second aspect above.

[0026] Since the vehicle provided in this application includes the interior rearview mirror assembly in the second aspect, it can solve the same technical problems as the aforementioned interior rearview mirror assembly and achieve the same technical effects, it will not be described again here.

Detailed Implementation

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0039] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, when describing pipelines, the terms "connected" and "linked" as used in this application have the meaning of establishing electrical connection. The specific meaning needs to be understood in conjunction with the context.

[0041] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0042] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0043] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an interior rearview mirror provided in the related art. The interior rearview mirror 10 includes a rearview mirror body 101, a connecting seat 102, and a connector 103. The connecting seat 102 is connected to the rearview mirror body 101, and the connector 103 is connected between the connecting seat 102 and the vehicle body 100, so as to install the rearview mirror body 101 onto the vehicle body 100 through the connecting seat 102 and the connector 103.

[0044] The connecting seat 102 is provided with a spherical connecting groove 1021. The connecting member 103 includes a connecting shaft 1031 and a spherical structure 1032. One end of the connecting shaft 1031 is connected to the vehicle body 100, and the other end of the connecting shaft 1031 is connected to the spherical structure 1032. The spherical structure 1032 is rotatably connected in the connecting groove 1021 so that the angle of the rearview mirror body 101 can be adjusted by the relative rotation of the spherical structure 1032 and the connecting seat 102, so that the driver and passengers can adjust the reflection range of the rearview mirror body 101 as needed.

[0045] Since the connecting groove 1021 is spherical, the spherical structure 1032 can rotate in any direction within the connecting groove 1021. Furthermore, due to the presence of the connecting shaft 1031, when the rearview mirror body 101 rotates too much relative to the spherical structure 1032, the connecting shaft 1031 will contact the connecting seat 102 and restrict the rearview mirror body 101 from continuing to rotate. At this time, the rearview mirror body 101 rotates to its limit position.

[0046] When the rearview mirror body 101 is rotated to its limit position, the connecting shaft 1031 will contact the connecting seat 102, thereby forming a fulcrum at the connection position between the connecting shaft 1031 and the connecting seat 102. If the rearview mirror body 10 is rotated with force or is impacted, the spherical structure 1032 may easily come out of the connecting groove 1021, thus rendering the rearview mirror 10 unusable and affecting the user experience of the rearview mirror 10.

[0047] Based on this, please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a vehicle 1000 provided in an embodiment of this application. This application provides a vehicle 1000. The vehicle 1000 can be a pure electric vehicle, a hybrid electric vehicle, a plug-in hybrid electric vehicle, a range-extended electric vehicle, a gasoline vehicle, etc.

[0048] Vehicle 1000 includes a body 100 and an interior rearview mirror assembly 200. A passenger compartment 100A is formed within the body 100, for accommodating occupants. The interior rearview mirror assembly 200 is located within the passenger compartment 100A and connected to the body 100, allowing occupants to observe the road conditions behind the vehicle 1000 and the status of rear passengers. In some examples, the interior rearview mirror assembly 200 is located above the windshield 300 of the vehicle 1000.

[0049] In some embodiments. See Figure 3 , Figure 3 This is a schematic diagram of the structure of an interior rearview mirror assembly 200 provided in an embodiment of this application. The interior rearview mirror assembly 200 includes a mirror body 1 and a connecting structure 2. The connecting structure 2 is connected to the mirror body 1 and to the vehicle body 100, so that the mirror body 1 is connected to the vehicle body 100 through the connecting structure 2.

[0050] Please refer to Figure 4 , Figure 4 for Figure 3The diagram shows a side view of the interior rearview mirror assembly 200. The mirror body 1 includes a housing 11 and a glass 12, with the glass 12 connected to the housing 11. The glass 12 reflects the road conditions behind the vehicle 1000 and the status of the rear passengers, allowing the driver and passengers to observe these conditions through the glass 12. A connecting structure 2 is attached to the side of the housing 11 opposite to the glass 12 to prevent the connecting structure 2 from affecting the reflection range of the glass 12.

[0051] In some embodiments, please continue reading Figure 3 and Figure 4 The connecting structure 2 includes a support 21, a connecting bracket 22, and a limiting member 23. (See also...) Figure 5 , Figure 5 for Figure 4 The diagram shows a cross-sectional view of the interior rearview mirror assembly 200. The support 21 includes opposing limiting surfaces 211 and a bottom surface 212. The support 21 has a mounting hole 213 recessed from the limiting surface 211 toward the bottom surface 212. For example, the mounting hole 213 can be a through hole or a blind hole.

[0052] The support 21 is connected to the mirror body 1. For example, the support 21 is connected to the outer shell 11 of the mirror body 1. The bottom surface 212 of the support 21 is located on the side of the limiting surface 211 facing the glass 12.

[0053] In some examples, the support 21 can be connected to the mirror body 1 by means of screwing, snap-fitting, riveting, etc. The support 21 can also be an integral structure with the outer shell 11.

[0054] The connecting bracket 22 includes a connecting rod 221 and a ball head 222 connected to the connecting rod 221. For example, one end of the connecting rod 221 is connected to the ball head 222, and the other end is connected to the vehicle body 100. The ball head 222 is rotatably connected within the mounting hole 213 and can rotate to its limit position relative to the support 21. The ball head 222 is spherical in shape and can rotate in any direction within the mounting hole 213. Therefore, the angle of the mirror body 1 can be adjusted by the relative rotation of the ball head 222 and the support 21, allowing the driver or passenger to adjust the angle of the mirror body 1 as needed.

[0055] In some examples, the ball head 222 can be interference-fitted with the support 21, and after an external force is applied to the mirror body 1, the ball head 222 and the support 21 can rotate relative to each other. In this way, after the mirror body 1 rotates to the appropriate position, the interference fit between the ball head 222 and the support 21 can keep the mirror body 1 stable.

[0056] The limiting member 23 is connected to the connecting rod 221 and is located on the side of the ball head 222 that is away from the bottom surface 212. When the ball head 222 is in the extreme position, the limiting member 23 is in contact with the limiting surface 211, and the connecting rod 221 is not in contact with the support 21.

[0057] In this way, by setting the limiting member 23, when the ball head 222 rotates to the limit position relative to the support 21, the limiting member 23 contacts the limiting surface 211 of the support 21, and the connecting rod 221 does not contact the support 21. This allows the limiting member 23 to limit the rotation range of the ball head 222 relative to the support 21, so as to prevent the ball head 222 from rotating excessively relative to the support 21 and dislodging from the mounting hole 213, thereby ensuring that the mirror body 1 can be used normally and improving the user experience of the interior rearview mirror assembly 200.

[0058] In some embodiments, please continue reading Figure 5 The surface of the ball head 222 includes a first plane 2221 and a second plane 2222 opposite to each other, and a spherical surface 2223 connecting the first plane 2221 and the second plane 2222. During the rotation of the ball head 222 relative to the support 21, the spherical surface 2223 contacts the inner wall of the mounting hole 213. The first plane 2221 is located on the side of the second plane 2222 opposite to the bottom surface 212, and the connecting rod 221 is connected to the first plane 2221.

[0059] Compared to a complete spherical structure, the ball head 222 is made into a first plane 2221, a second plane 2222, and a spherical surface 2223. This reduces the volume of the ball head 222, thereby reducing the volume of the mounting hole 213 and allowing the mounting hole 213 to better accommodate the ball head 222, further reducing the risk of the ball head 222 coming out of the mounting hole 213.

[0060] Furthermore, the connecting rod 221 is connected to the first plane 2221, which also facilitates the connection between the connecting rod 221 and the ball head 222. In some examples, the connecting rod 221 and the ball head 222 can be an integral structure. In other examples, the connecting rod 221 can also be connected to the ball head 222 by means of snap-fit, screw-fit, riveting, welding, etc.

[0061] Furthermore, with the ball head 222 configured as described above, when the ball head 222 rotates to its limit position relative to the support 21, due to the limiting effect of the limiting member 23, the spherical surface 2223 of the ball head 222 can be located more within the mounting hole 213, thereby reducing the risk of the ball head 222 coming out of the mounting hole 213.

[0062] In some other embodiments, the surface of the ball head 222 may also be a complete spherical structure. Alternatively, the surface of the ball head 222 may be divided into two parts, one part being a plane and the other part being a spherical structure.

[0063] In some embodiments, please continue reading Figure 5 The mounting hole 213 includes a straight hole portion 2131 and a spherical hole portion 2132. The straight hole portion 2131 is located on the side of the spherical hole portion 2132 opposite to the bottom surface 212, and at least a portion of the spherical surface 2223 is located within the spherical hole portion 2132. The inner wall surface of the spherical hole portion 2132 is spherical, and the radial dimension of the spherical hole portion 2132 is larger than the radial dimension of the straight hole portion 2131. The spherical surface 2223 of the ball head 222 can contact the inner wall surface of the spherical hole portion 2132.

[0064] In this way, if the ball head 222 comes out of the spherical hole 2132, it needs to go through the straight hole 2131 to completely come out of the mounting hole 213. Therefore, the cooperation between the straight hole 2131 and the spherical hole 2132 can better restrict the ball head 222 within the spherical hole 2132, thereby further reducing the risk of the ball head 222 coming out of the mounting hole 213.

[0065] In some embodiments, please continue reading Figure 5 The inner circumferential surface of the straight hole 2131 is a conical surface 2131A. The radial dimension of the end of the conical surface 2131A facing away from the bottom surface 212 is greater than the radial dimension of the end of the conical surface 2131A facing the bottom surface 212. That is to say, the straight hole 2131 is a conical hole, and the opening of the end of the straight hole 2131 facing away from the bottom surface 212 is larger than the opening of the end of the straight hole 2131 facing the bottom surface 212.

[0066] This reduces the restriction imposed by the straight hole 2131 on the ball head 222 or the connecting rod 221, ensuring the rotation range of the ball head 222 relative to the support 21, thereby ensuring the adjustment range of the mirror body 1. Furthermore, in conjunction with the function of the limiting member 23, it ensures the adjustment range of the mirror body 1 while preventing the ball head 222 from dislodging from the mounting hole 213.

[0067] In some other embodiments, the straight hole 2131 may also be a cylindrical hole or a hole of other shapes. This application does not specifically limit it in this regard.

[0068] In some other embodiments, the mounting hole 213 may also be a cylindrical hole, a spherical hole, or other holes that can restrict the ball head 222 and allow the ball head 222 to rotate.

[0069] In some embodiments, please continue reading Figure 5The limiting member 23 is spaced apart from the first plane 2221. In this way, there is a certain distance between the limiting member 23 and the first plane 2221. Compared with the limiting member 23 being in contact with the first plane 2221, when the ball head 222 rotates to the limit position relative to the support 21, the rotation amplitude of the ball head 222 is larger. This allows the limiting member 23 to prevent the ball head 222 from dislodging from the mounting hole 213, and also avoids the limiting member 23 restricting the ball head 222 to rotate too little relative to the support 21, which would affect the adjustment range of the mirror body 1.

[0070] In some other embodiments, the limiting member 23 may also contact the first plane 2221.

[0071] In some embodiments, please continue reading Figure 5 The limiting member 23 includes a first direction (e.g., Figure 5 The limiting protrusion 231 of the connecting rod 221 protrudes in the direction X shown in the figure, and the first direction is perpendicular to the extension direction of the connecting rod 221. By providing the limiting protrusion 231 on the connecting rod 221, the ball head 222 can be restricted by the limiting protrusion 231 to avoid excessive rotation of the ball head 222 relative to the support 21. It also facilitates the processing of the connecting rod 221 and the limiting member 23, and the structure of the connecting rod 221 and the limiting member 23 is relatively simple, thereby simplifying the structure of the connecting structure 2.

[0072] In some examples, the limiting protrusion 231 and the connecting rod 221 can be an integral structure, or they can be connected by snap-fit, screw-fit, riveting, or other methods.

[0073] In some embodiments, the limiting protrusion 231 surrounds the connecting rod 221. In this way, no matter which direction the ball head 222 rotates relative to the support 21 to its limit position, the limiting protrusion 231 can limit the ball head 222 to avoid excessive rotation of the ball head 222 relative to the support 21, thereby better preventing the ball head 222 from coming out of the mounting hole 213.

[0074] In some other embodiments, there are multiple limiting protrusions 231, which are spaced apart around the connecting rod 221. This allows the multiple limiting protrusions 231 to restrict the ball head 222 from different directions, preventing excessive rotation of the ball head 222 relative to the support 21 and thus preventing the ball head 222 from dislodging from the mounting hole 213. This also saves material and reduces costs.

[0075] In other embodiments, the limiting member 23 may also be a ring-shaped structure, rod-shaped structure, plate-shaped structure, block-shaped structure, etc., connected to the connecting rod 221 by means of snap-fit, screw connection, or other connection methods.
