Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile accessories, especially to a wear-resistant structure for connecting a support on an automobile mirror to a mirror arm. BACKGROUND

[0002] In the field of automobile parts, the connection technology between the automobile mirror and the support has been evolving with the development of the automobile industry. In the early stage, the connection design of the automobile mirror and the support was relatively simple and direct, mainly focusing on meeting the basic installation requirements to enable the mirror to be fixed at a suitable position on the vehicle body to provide the driver with a rear view. Traditionally, simple connectors made of ordinary metal or plastic materials are commonly used, such as directly fixing the mirror arm to the support with bolts. This connection method can initially meet the stable installation of the rearview mirror in the stationary state of the vehicle. On the one hand, due to the constant bumps and vibrations encountered during vehicle operation, such as driving on bumpy roads, passing through speed bumps, etc., the mirror arm and the support connected by simple bolts lack effective buffering structures, and the hard connection causes stress concentration at the connection, which leads to accelerated wear after long-term accumulation. According to relevant data, an ordinary family car may fold the rearview mirror 2-3 times a day on average if used normally every day. After frequent use for several months to a year, the wear at the connection between the support and the mirror arm of the traditional connection structure can reach several millimeters, and the fitting clearance increases significantly, directly causing the rearview mirror to shake when folding, affecting the clarity and accuracy of the driver's observation of the rear, and even in extreme cases, the angle of the rearview mirror may be out of control, posing a safety hazard. On the other hand, to meet the adjustment needs of the rearview mirror position in different driving scenarios, such as folding the rearview mirror to avoid scratching when parking and fine-tuning the angle to reduce wind resistance when driving at high speed, the rearview mirror needs to be frequently operated. However, the traditional connection structure does not have an optimization mechanism specifically designed for frequent operation, and each adjustment of the angle may cause additional wear to the connection part, further shortening its service life. Moreover, once the wear is severe, the entire support part often needs to be replaced, which not only increases the procurement cost of the parts, but also involves complicated processes such as manual disassembly and installation during the replacement process, resulting in a significant increase in maintenance costs. Traditional heavy metal connectors are not conducive to achieving the goal of lightweight vehicles, while some simple plastic connectors have insufficient strength and poor wear resistance, making it difficult to meet multiple requirements. In summary, the existing connection technology between the automobile mirror and the support needs to be improved to meet the various requirements of modern automobile development.

[0003] The traditional automobile mirror support and mirror arm connecting structure does not fully consider the wear condition of long-term and frequent use in material selection, with the increasing folding times of the rearview mirror, the mutual friction of the cooperation components made of ordinary materials causes the wear of the support structure cooperation part to aggravate, and the cooperation gap rapidly increases, which not only affects the smoothness of the rearview mirror folding, but also causes the obvious shaking phenomenon of the upper support part in the later period, seriously affects the use experience, and even may interfere with the driver's observation of the rear road condition, and brings safety hazards. Content of the utility model

[0012] Beneficial effects

[0013] The utility model discloses a damping bowl and damping seat made of special POM material, which have excellent wear resistance and self-lubricating property compared with traditional materials. During frequent folding of the rearview mirror, the mirror arm body and the support body utilize the damping bowl and the damping seat to effectively buffer the motion impact and reduce friction and wear, greatly slowing down the wear rate of the support structure at the fitting position, keeping the fitting gap stable for a long time, avoiding the folding shaking problem at the support position due to wear, fundamentally prolonging the service life of the connecting structure and the entire rearview mirror system, reducing the frequency of replacing the support part due to severe wear, reducing the vehicle maintenance cost, saving the expenses for the vehicle owner, and reducing the time cost and resource waste caused by replacement of parts.

[0014] In the utility model, the mirror arm body and the support body are connected through a fastening connection system composed of a positioning nut, a positioning bolt and a gasket, which ensures the accurate relative position of the two in three-dimensional space. Even when the vehicle is running on a bumpy road or the rearview mirror is frequently adjusted, the connection part can be effectively prevented from loosening and displacement. The coordinated work of the guide shaft, the damping seat and the damping bowl provides accurate guidance for the rotational fitting of the support body and the mirror arm body, and further buffers external force impact, making the folding and adjustment of the rearview mirror more stable and smooth. The stable and reliable rearview mirror connecting structure can enable the driver to clearly and accurately observe the road conditions behind during driving, make correct driving decisions in time, and thus provide strong guarantee for driving safety.

[0022] In order to make the technical means, creation characteristics, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the utility model.

[0023] The specific embodiments of the utility model are described below in combination with the drawings. Embodiment one

[0025] With reference to Figures 1 to 5 The automobile mirror upper support and mirror arm connecting wear-resistant structure comprises a mirror arm body 1 and a support body 2, a guide shaft 7 at the top end of the mirror arm body 1 provides a positioning reference for the installation of subsequent components, and the stability of the whole connecting structure during vehicle driving and rearview mirror operation is maintained through the structural strength of the mirror arm body 1; when the rearview mirror is folded or the angle is adjusted, the mirror arm body 1 is stressed and transmits the force to the vehicle body connecting part; during vehicle driving, the mirror arm body 1 always maintains a relatively fixed position, and the connecting part of the mirror arm body 1 and the support body 2 cooperates to ensure the stability and reliability of the rearview mirror. For example, when encountering bumpy road conditions, the mirror arm body 1 buffers part of the vibration to avoid excessive impact on the connecting part; the support body 2 cooperates with the mirror arm body 1 to realize the installation and angle adjustment of the rearview mirror, is a key transfer component connecting the vehicle body and the mirror arm of the rearview mirror, bears the weight of the rearview mirror and external force, the top surface of the mirror arm body 1 and the bottom surface of the support body 2 are clamped with each other through protrusions and grooves, and the protrusions and the grooves are both circular ring structures; the bottom surface is connected with the mirror arm body 1 in multiple ways, such as the clamping structure of the protrusions and the grooves, so that the relative position of the two is fixed and a certain rotational freedom is realized to meet the folding requirement of the rearview mirror. At the same time, the mirror arm body 1 is closely connected with the mirror arm body 1 through a positioning bolt 3, a positioning nut 4 and a gasket 5, the firmness of the connection is ensured, the top end of the mirror arm body 1 is provided with a guide shaft 7, a damping seat 8 is sleeved on the surface of the guide shaft 7, a damping bowl 6 is sleeved on the outside of the damping seat 8, positioning holes 9 are penetrated on the surfaces of the mirror arm body 1 and the support body 2, a positioning bolt 3 is penetrated in the positioning holes 9, a positioning nut 4 is arranged at the top end of the positioning bolt 3, the positioning nut 4 is located at the top of the support body 2, and a gasket 5 is arranged between the positioning nut 4 and the top surface of the support body 2.

[0026] The guide shaft 7 provides accurate positioning guide for the installation of the damping seat 8 and the damping bowl 6, ensures the correct installation position of the two at the top end of the mirror arm body 1, and is also an auxiliary positioning structure when the support body 2 is connected with the mirror arm body 1. The top end of the guide shaft 7 is clamped with the bottom surface of the support body 2, and the positioning hole 9 on the surface of the guide shaft 7 is close to the bottom end position. The hole diameter is matched with the gap at the top end of the guide shaft 7, the surface of the shaft is smooth, the damping seat 8 can be smoothly sleeved, and the accurate size design ensures the cooperation accuracy with other parts. When the rearview mirror is folded, the guide shaft 7 bears a certain lateral force and maintains the stability of the structure by using its rigidity. During the operation of the rearview mirror, the guide shaft 7 always restricts the relative movement direction of the damping seat 8, the damping bowl 6 and the support body 2 as the core positioning reference, so that the components move in an orderly manner around it, ensures the consistency of each folding or angle adjustment action, improves the accuracy of component installation, reduces wear and functional problems caused by installation errors, enhances the reliability of the entire connecting structure during repeated movement, and prolongs the service life.

[0027] The damping seat 8 cooperates with the damping bowl 6 to play a role in buffering, damping and increasing friction resistance, reduces impact and wear during folding of the rearview mirror, ensures the stability of movement, the damping bowl 6 is sleeved on the surface of the guide shaft 7, and the inner wall of the damping bowl 6 is movably connected with the outer wall of the damping seat 8. When the rearview mirror is folded or the angle is adjusted, the friction between the damping seat 8 and the damping bowl 6 due to relative movement consumes part of the energy, thereby slowing down the movement speed and avoiding hard collision between components. With frequent operation of the rearview mirror, the damping seat 8 moves on the guide shaft 7, and the friction characteristics of the damping seat 8 and the damping bowl 6 are dynamically adjusted according to the movement speed and pressure, which always controls the movement of the rearview mirror within a stable and soft range, effectively reduces the wear of components, especially in the case of long-term and frequent folding of the rearview mirror, reduces the wear amount at the matching position of the support body 2 and the mirror arm body 1, prolongs the service life of the connecting structure, and reduces the maintenance cost in the later period.

[0028] The damping bowl 6 cooperates with the damping seat 8 to provide friction resistance and buffering, and improves wear resistance by using its special material properties, protects the connecting structure from excessive wear, the bottom surface of the damping seat 8 is coplanar with the top surface of the mirror arm body 1, the vertical center line of the damping seat 8, the vertical center line of the guide shaft 7, the vertical center line of the damping bowl 6, the vertical center line of the positioning hole 9 and the vertical center line of the positioning bolt 3 all coincide with each other, the damping bowl 6 and the damping seat 8 are cut and formed by POM material, and the damping bowl 6 and the damping seat 8 are both circular truncated cone structures with the bottom surface size larger than the top surface size, when external force makes the rearview mirror fold or adjust, relative sliding friction occurs between the damping bowl 6 and the damping seat 8, the material POM has good self-lubricating property and wear resistance, so that the friction process is smooth and the wear is small, in daily driving, each time the rearview mirror is operated, the damping bowl 6 and the damping seat 8 will interact, the damping bowl 6 converts kinetic energy into heat energy according to its shape and material properties, and at the same time restricts the movement range of the damping seat 8, ensures the stability of the connecting structure, greatly enhances the wear resistance of the connecting structure, compared with the traditional connection method, can significantly reduce the problem of increasing gap caused by wear, ensures that the rearview mirror can still be stably folded after long-term use, and the support body 2 does not need to be frequently replaced, saving cost.

[0029] The positioning hole 9 provides a channel for the positioning bolt 3 to pass through, realizes the mechanical connection of the mirror arm body 1 and the support body 2, ensures the relative position of the two in three-dimensional space, and is a key structure to ensure the reliability of the connection, the positioning hole 9 vertically penetrates along the top surface and the bottom surface of the mirror arm body 1, the positioning hole 9 on the surface of the support body 2 vertically penetrates along the top surface and the bottom surface, so that the positioning bolt 3 can pass vertically, by tightening the positioning nut 4 to apply pressure at both ends, the mirror arm body 1 and the support body 2 are tightly pressed together, during installation, first pass the positioning bolt 3 through the positioning hole 9, then tighten the positioning nut 4 on the top of the support body 2, the gasket 5 plays the role of dispersing pressure and preventing the nut from loosening, so that the positioning hole 9 and the positioning bolt 3 always maintain close cooperation during the driving and use of the rearview mirror, maintain the stability of the connecting structure, provide a simple and reliable connection method, ensure that the mirror arm body 1 and the support body 2 will not displace or separate during long-term use, ensure the normal function of the rearview mirror, and improve the driving safety.

[0030] The positioning bolt 3 is used as a main connecting piece connecting the mirror arm body 1 and the support body 2, and through cooperation with the positioning hole 9 and the positioning nut 4, the positioning bolt 3 applies a fastening force to firmly combine the mirror arm body 1 and the support body 2 together. After passing through the positioning hole 9, the positioning bolt 3 is screwed with the positioning nut 4 through a threaded structure. When the positioning nut 4 is tightened, the positioning bolt 3 bears a tension force to pull the mirror arm body 1 and the support body 2 towards the middle, thereby forming a stable connection. During the entire service life of the rearview mirror, the positioning bolt 3 continuously bears the tension force. Whether it is the vibration of the vehicle during normal driving or the external force during folding of the rearview mirror, the high-strength mechanical properties of the positioning bolt 3 maintain the fastening of the connection, prevent loosening, and achieve reliable connection of the mirror arm body 1 and the support body 2 in a simple and efficient manner. The rearview mirror can stably work under various working conditions, and the safety hazards caused by loosening of the connection are reduced.

[0031] The positioning nut 4 cooperates with the positioning bolt 3 to be tightened to press the mirror arm body 1 and the support body 2 tightly, adjust the fastening degree of the connection, and provide a mounting basis for the gasket 5. The positioning nut 4 is screwed with the positioning bolt 3 through a threaded structure. When the positioning nut 4 is rotated and tightened, an axial tension force is transmitted to the positioning bolt 3 to make the mirror arm body 1 and the support body 2 tightly fit, and the gasket 5 is compressed tightly. The elastic and frictional force of the gasket 5 further enhances the connection stability. During installation or later maintenance inspection, the positioning nut 4 is rotated by a wrench or the like. The fastening force is adjusted according to actual needs to ensure that the rearview mirror connection structure can meet the stability requirements at different use stages, and the fastening control of the connection structure is conveniently and quickly achieved. The positioning nut 4, the positioning bolt 3 and the gasket 5 jointly act to ensure reliable connection of the rearview mirror and adapt to different use environments and working condition requirements.

[0032] The gasket 5 is arranged between the positioning nut 4 and the top surface of the support body 2 to disperse pressure, prevent loosening of the nut, reduce friction and wear, and enhance the sealing performance of the connection. When the positioning nut 4 is tightened, the gasket 5 is deformed by extrusion to fill the small gap between the positioning nut 4 and the support body 2, and evenly disperse the concentrated pressure to the surface of the support body 2. The rough surface of the gasket 5 increases the frictional force to prevent the positioning nut 4 from rotating and loosening due to vibration and the like. During driving of the vehicle, the gasket 5 continuously plays a buffering and anti-loosening role with the body vibration of the vehicle to ensure that the positioning nut 4 is always in a tightened state, maintain the firm connection of the mirror arm body 1 and the support body 2, improve the stability and reliability of the connection structure, prolong the service life of the connection components, reduce problems such as shaking and displacement of the rearview mirror caused by loosening of the nut, and ensure driving safety.

[0033] In summary, the automobile mirror support and mirror arm connection wear-resistant structure effectively solves the problems of insufficient wear resistance and high later-stage cost in the connection of the existing automobile mirror support and mirror arm, and improves the performance and reliability of the rearview mirror connection structure. Specific embodiment two:

[0035] Reference Figures 1 to 5 According to the above specific embodiments, the following is further disclosed:

[0036] Angle adjustment and folding function: when the driver needs to adjust the angle of the rearview mirror, external force acts on the mirror arm body 1, and the mirror arm body 1 rotates around the rotating connection point formed by the protrusion and the recess of the support body 2. Because the top end of the guide shaft 7 is engaged with the bottom surface of the support body 2, and the damping seat 8 on the surface of the guide shaft 7 is tightly matched with the damping bowl 6, and the damping bowl 6 is sleeved on the surface of the guide shaft 7 and the inner wall is movably connected with the outer wall of the damping seat 8, the rotation of the mirror arm body 1 is constrained by the friction between the damping seat 8 and the damping bowl 6, and the rotation process becomes smooth and slow, avoiding the possibility of out-of-control or collision of the rearview mirror due to rapid rotation.

[0037] In the folding operation of the rearview mirror, based on the above structure, the mirror arm body 1 rotates towards the vehicle body, and the damping seat 8 and the damping bowl 6 slide relative to each other. By utilizing the good self-lubricating property and wear resistance of POM material, the energy consumed in the folding process is consumed, and the impact of external force is buffered, so that the rearview mirror can complete the folding action gently and smoothly, and effectively prevent damage to the components caused by hard collision during folding.

[0038] Stable support and damping function: the mirror arm body 1 and the support body 2 are connected together by the positioning bolt 3, the positioning nut 4 and the gasket 5. The positioning bolt 3 passes through the positioning hole 9 vertically through the surface of the mirror arm body 1 and the support body 2, and after the positioning nut 4 is tightened, the mirror arm body 1 and the support body 2 are tightly pressed together, and the gasket 5 disperses the pressure applied by the positioning nut 4, preventing the nut from loosening, while also enhancing the sealing of the connection part. This stable connection structure provides a solid support foundation for the rearview mirror, ensuring that even if the vehicle encounters bumpy road conditions during driving, the rearview mirror can be stably fixed on the support without shaking or displacement.

[0039] The damping seat 8 and the damping bowl 6 continuously play a damping role in daily driving. When the vehicle vibrates, the rearview mirror is affected and produces slight vibration. The friction between the damping seat 8 and the damping bowl 6 and the relative movement of the damping seat 8 on the guide shaft 7 convert the vibration energy into heat energy and dissipate it, effectively suppressing the vibration amplitude of the rearview mirror, ensuring that the driver's view of the rear road conditions through the rearview mirror is clear and stable.

[0040] The installation steps are as follows: the damping seat 8 is sleeved on the surface of the guide shaft 7, the bottom surface of the damping seat 8 is coplanar with the top surface of the mirror arm body 1, and the vertical center line of the damping seat 8 coincides with the vertical center line of the guide shaft 7, so as to ensure the accuracy of the installation position, at this time, the damping seat 8 can smoothly slide on the guide shaft 7, laying a foundation for subsequent installation; the damping bowl 6 is sleeved on the surface of the guide shaft 7, the inner wall of the damping bowl 6 is movably connected with the outer wall of the damping seat 8, and the vertical center line of the damping bowl 6 also coincides with the vertical center line of the guide shaft 7, and attention should be paid to ensuring that the damping bowl 6 is firmly installed and cannot be loose or displaced, so that the damping bowl 6 and the damping seat 8 can work cooperatively to play the buffering and wear-resistant functions; the top end of the mirror arm body 1 with the installed damping structure is aligned with the bottom surface of the support body 2, so that the top end of the guide shaft 7 is clamped with the bottom surface of the support body 2, and the top surface of the mirror arm body 1 and the bottom surface of the support body 2 are clamped with each other through the protrusion and the groove, so as to preliminarily fix the relative position of the two, ensuring that the two will not be misaligned in the subsequent installation process; the positioning bolt 3 is used to pass through the vertical positioning hole 9 on the surface of the mirror arm body 1 and the support body 2, and attention should be paid to the fact that the hole diameter is matched with the positioning bolt 3, and the positioning hole 9 on the surface of the positioning bolt 3 is close to the bottom end, and the hole diameter is matched with the gap at the top end of the guide shaft 7, so as to ensure that the positioning bolt 3 can be smoothly inserted and accurately positioned; the end of the positioning bolt 3 passing out of the top of the support body 2 is screwed with the positioning nut 4, and then the gasket 5 is placed between the positioning nut 4 and the top surface of the support body 2, and the positioning nut 4 is tightened by using a wrench or the like, so as to make the mirror arm body 1 and the support body 2 closely adhere to each other by adjusting the tightening degree, and finally the installation is completed. At this time, the rearview mirror is connected with the vehicle body through the support body 2, and can be normally used.

[0041] Through the above working principle and installation steps, the wear-resistant structure for connecting the mirror arm and the support body on the automobile mirror can efficiently and stably operate, and can provide reliable support and adjustment functions for the automobile rearview mirror.

[0042] In summary:
