Bracket assembly, windshield assembly and vehicle

Abstract

This application relates to a bracket assembly, a windshield assembly, and a vehicle. When an optical element is assembled on the bracket body or removed, the limiting member is in a loosened position, and each abutment part and clamping arm is separated from each other. When the fixed shaft is inserted between the two clamping arms, it can push the two clamping arms apart. When the fixed shaft is pulled out of the two clamping arms, it can also push the two clamping arms apart. When the optical element is inserted between the two clamping arms, the limiting member is in a pressed position, and each abutment part abuts against each clamping arm, so that the two clamping arms are tightly abutted against the opposite sides of the fixed shaft. This ensures that the insertion force of the optical element is small and the extraction force is large during the assembly process. In addition, the tension of the retaining spring remains unchanged, and the extraction force between the retaining spring and the fixed shaft is stable over a long period of time. Furthermore, the interference fit between the retaining spring and the fixed shaft can be reduced to reduce the insertion force.

Description

Technical Field

[0001] This application relates to the field of optical component mounting technology, and in particular to a bracket assembly, a windshield assembly, and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, the application of safety systems using cameras, video cameras, ADAS cameras, LiDAR, or other optical sensors as optical components is growing rapidly. Generally, optical components are mounted on the windshield via brackets. To improve the operability and convenience of installation and maintenance of optical components on the brackets, they are usually mounted in a detachable manner.

[0003] In related technologies, optical components have a fixed shaft, and a retaining ring is mounted on the bracket, with the fixed shaft snapped into the retaining ring. However, clients have strict requirements regarding the insertion and extraction forces during the matching process between the camera's fixed shaft and the retaining ring, demanding a small insertion force and a large extraction force. To securely fix the camera and prevent inaccurate signal acquisition due to camera shake on bumpy roads, the retaining ring must exert a sufficiently large holding force on the fixed shaft, requiring a large extraction force to pull out the optical component. However, this also results in a large insertion force being needed to insert the optical component into the retaining ring during assembly, making assembly difficult and prone to deformation and failure of the retaining ring due to improper force application. Furthermore, after prolonged use, the holding force of the retaining ring on the fixed shaft weakens, making the optical component more susceptible to vibration under external forces, leading to decreased installation stability. Summary of the Invention

[0004] Therefore, it is necessary to overcome the shortcomings of the existing technology and provide a bracket assembly, windshield assembly and vehicle that can reduce the assembly difficulty of optical components, prevent the snap ring from deforming and failing during the assembly process, and at the same time achieve long-term stability of the optical component snap-fit.

[0011] In one embodiment, the limiting cover is provided with a first limiting plate that is engaged with the first mounting plate, and two second limiting plates that are engaged with the two second mounting plates respectively; both second limiting plates are connected to the first limiting plate.

[0012] In one embodiment, the outer wall of the first mounting plate is provided with a first locking block, and the first limiting plate is provided with a first locking slot corresponding to the first locking block, and the first locking block is inserted into the first locking slot; the outer wall of the second mounting plate is provided with a second locking block, and the second limiting plate is provided with a second locking slot corresponding to the second locking block, and the second locking block is inserted into the second locking slot.

[0013] In one embodiment, the mounting portion further includes a first support portion connected to the first mounting plate and located in the mounting space; the first support portion passes through the snap ring, and the top surface of the first support portion is used to support the fixed shaft.

[0014] In one embodiment, the mounting portion further includes a second support portion connected to the first mounting plate and located in the mounting space; the second support portion and the first support portion are spaced apart to form a positioning space, and the first connecting arm passes through the positioning space.

[0015] In one embodiment, the inner wall of the positioning space is provided with a first snap-fit ​​portion, and the first connecting arm is provided with a second snap-fit ​​portion that snaps into and engages with the first snap-fit ​​portion.

[0016] In one embodiment, the opposite sides of the first support portion are respectively connected to the two second mounting plates with movable intervals, and the two clamping arms are respectively inserted into the two movable intervals.

[0017] In one embodiment, the support assembly further includes a damping member connected to the limiting member, the damping member being connected to the support body.

[0023] The aforementioned bracket assembly, windshield assembly, and vehicle, due to the inclusion of limiting components with both clamping and releasing positions, allow for several advantages. When optical elements are mounted on the bracket body or removed, the limiting components are in the released position, separating the abutment parts from the clamping arms. This allows the fixing shaft to smoothly push the two clamping arms apart when inserted, requiring minimal insertion force and facilitating installation. Similarly, pulling the fixing shaft outward from the two clamping arms facilitates disassembly. After the optical element is inserted into the area between the two clamping arms, the limiting member is in the clamping position, and each abutting part abuts against each clamping arm, so that the two clamping arms are tightly abutted against the opposite sides of the fixed shaft.

In addition, under the action of the limiting member, the tension of the snap ring is kept constant, and the extraction force between the snap ring and the fixed shaft is consistently met over a long period of time. Furthermore, the interference between the snap ring and the fixed shaft can be reduced to reduce the insertion force. Attached Figure Description

Detailed Implementation

[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0045] As described in the background section, the assembly process of the retaining ring and fixed shaft in related technologies requires a large insertion force to insert the optical element into the retaining ring, making assembly difficult and prone to deformation and failure due to improper force application. Furthermore, after the optical element has been used for a considerable period, the retaining force of the retaining ring on the fixed shaft weakens, making the optical element prone to vibration under external forces and resulting in decreased installation stability. The inventors' research revealed that this problem arises because the tension of the retaining ring is greater in the initial stage than in the later stage. This necessitates a larger insertion force during the initial assembly stage to insert the optical element into the retaining ring, making assembly difficult and prone to deformation and failure. Additionally, the retaining ring and fixed shaft are constantly under stress after assembly. Prolonged stress causes the retaining ring to gradually deform, and the tension of the retaining ring gradually decreases with extended use, significantly reducing the stability of the optical element in later stages, thus leading to vibration of the optical element.

[0046] For the reasons mentioned above, this application provides a bracket assembly, a windshield assembly, and a vehicle, which can reduce the assembly difficulty of optical components, prevent the snap ring from deforming and failing during the assembly process, and also achieve a long-term stable solution for the snap-fit ​​of optical components.

[0047] See Figures 1 to 7 Or refer to Figures 8 to 13 , Figures 1 to 7 A schematic diagram of the structure of one embodiment of the support assembly is shown; Figures 8 to 13 A structural schematic diagram of a support assembly according to another embodiment is shown. Figures 1 to 7 The bracket assembly shown is Figures 8 to 13The main differences between the bracket assemblies shown lie in the specific structural form of the limiting member 40 and the insertion / removal direction of the limiting member 40 on the mounting portion 20. One embodiment of this application provides a bracket assembly including a bracket body 50, which has a mounting portion 20 for mounting a fixed shaft 11 of an optical element 10. The optical element 10 includes, but is not limited to, a camera, video camera, ADAS camera, LiDAR, or other optical sensors. The bracket assembly also includes a retaining spring 30 and a limiting member 40. The retaining spring 30 is disposed on the mounting portion 20 and includes two clamping arms 31 arranged at a distance from each other and a first connecting arm 32 connecting the two clamping arms 31. The two clamping arms 31 are used to clamp onto opposite sides of the fixed shaft 11. The limiting member 40 is provided on the mounting part 20. The limiting member 40 has two abutting parts 41. The limiting member 40 has a pressing position and a releasing position. When the limiting member 40 is in the pressing position, each abutting part 41 abuts against each clamping arm 31, so that the two clamping arms 31 are tightly abutted against the opposite sides of the fixed shaft 11 respectively. When the limiting member 40 is in the releasing position, each abutting part 41 and each clamping arm 31 are separated from each other.

[0048] The aforementioned bracket assembly, due to the presence of a limiting member 40, which has both a pressing position and a releasing position, allows the limiting member 40 to be in the releasing position when the optical element 10 is assembled onto the bracket body 50 or when it is disassembled and removed. This releases the contact parts 41 and the clamping arms 31, separating them. The fixing shaft 11, when inserted between the two clamping arms 31, can smoothly push the two clamping arms 31 apart with minimal insertion force, facilitating the insertion operation. Similarly, when the fixing shaft 11 is pulled outward from the two clamping arms 31, it can smoothly push the two clamping arms 31 apart, facilitating disassembly. When the optical element 10 is... After the optical element 10 is inserted into the area between the two clamping arms 31, the limiting member 40 is in the pressing position, and each abutting part 41 abuts against each clamping arm 31, so that the two clamping arms 31 are tightly abutted against the opposite sides of the fixed shaft 11. This ensures that the optical element 10 has a small insertion force and a large pull-out force during the assembly process. In addition, under the action of the limiting member 40, the tension of the retaining spring 30 can be kept constant, and the pull-out force between the retaining spring 30 and the fixed shaft 11 can be stably met in the long term. In addition, the interference between the retaining spring 30 and the fixed shaft 11 can be reduced to reduce the insertion force.

[0049] In some embodiments, the limiting member 40 can be either non-removably disposed on the mounting portion 20 or detachably mounted on the mounting portion 20, as long as the limiting member 40 has a pressing position and a releasing position. In this embodiment, the limiting member 40 is specifically disposed detachably on the mounting portion 20. When the limiting member 40 is mounted on the mounting portion 20, the limiting member 40 is in the pressing position; when the limiting member 40 is removed from the mounting portion 20, the limiting member 40 is in the releasing position because the abutting portion 41 of the limiting member 40 separates from the clamping arm 31.

[0050] The detachable method of the limiting member 40 on the mounting part 20 includes, but is not limited to, being set as a snap-fit, being detachably connected by connecting parts such as pins, rivets, screws, bolts, ropes, etc., or being set as other detachable methods according to actual needs, which are not limited here.

[0051] Please see Figures 2 to 4 or Figures 5 to 7 or Figure 9 and Figure 10 or Figures 11 to 13 In one specific embodiment, the limiting member 40 is detachably snapped onto the mounting portion 20. In this way, the limiting member 40 is easy to install and remove, that is, it can be easily switched between the pressed position and the released position, thereby facilitating the installation and removal of the optical element 10 on the bracket body 50.

[0052] Please see Figure 3 and Figure 4 or Figure 9 and Figure 10 or Figure 12 and Figure 13 In one embodiment, the mounting portion 20 is provided with a first mounting plate 21 that abuts against the end face of the fixed shaft 11 and two second mounting plates 22 located on opposite sides of the retaining spring 30. The retaining spring 30 is disposed in the mounting space 23 formed by the first mounting plate 21 and the two second mounting plates 22. Thus, after the retaining spring 30 is disposed in the mounting space 23 formed by the first mounting plate 21 and the two second mounting plates 22, on the one hand, the first mounting plate 21 improves the stability of the fixed shaft 11 by abutting against the end face of the fixed shaft 11; on the other hand, the two second mounting plates 22 located on opposite sides of the retaining spring 30 limit the two clamping arms 31 of the retaining spring 30, resulting in better stability.

[0053] Please see Figures 2 to 4 , Figure 6 and Figure 7In one embodiment, the first mounting plate 21 is provided with a first snap-fit ​​hole 211, and the limiting member 40 is provided with a first buckle 42 that engages with the first snap-fit ​​hole 211. The first buckle 42 is snapped into the first snap-fit ​​hole 211. Thus, during the assembly of the limiting member 40 to the mounting part 20, it is fixed by the first buckle 42 snapping into the first snap-fit ​​hole 211, and at the same time, the two abutting parts 41 of the limiting member 40 respectively abut and fix to the two clamping arms 31.

[0054] In addition, the first mounting plate 21 is also provided with a first insertion hole corresponding to the position of the abutment part 41, so that the abutment part 41 can be inserted through the first insertion hole during assembly. Specifically, the first insertion hole and the first snap-fit ​​hole 211 are connected and formed as one piece, for example, it is set as a strip-shaped opening, so as to facilitate processing and manufacturing.

[0055] In another embodiment, the first mounting plate 21 may also be provided with a second buckle, and the limiting member 40 is provided with a second snap-fit ​​hole that engages with the second buckle, and the second buckle is snapped into the second snap-fit ​​hole.

[0056] Please see Figure 3 and Figure 4 In one embodiment, the first latch 42 and the first latching hole 211 are located outside the areas where the two second mounting plates 22 are opposite to each other. Similarly, the second latch and the second latching hole are located outside the areas where the two second mounting plates 22 are opposite to each other. Thus, the first latch 42 and the first latching hole 211 are not obstructed by the two second mounting plates 22, making them easily obstructed and facilitating disassembly. Likewise, the second latch and the second latching hole are not obstructed by the two second mounting plates 22, making them easily obstructed and facilitating disassembly.

[0057] Please see Figure 3 and Figure 4 In one embodiment, each of the two clamping arms 31 has a flange 311 disposed away from the end of the first connecting arm 32. Specifically, each clamping arm 31 also has a first clamping segment 312, and the two first clamping segments 312 are disposed at a distance from each other, for example, they are disposed parallel to each other. Each first clamping segment 312 is correspondingly connected to each flange 311, and a chamfer is provided at the connection position between the first clamping segment 312 and the flange 311. Thus, during the process of inserting the fixed shaft 11 into the gap between the two clamping arms 31, the two chamfers guide the fixed shaft 11, which facilitates the smooth engagement of the fixed shaft 11 into the retaining spring 30.

[0058] Please see Figure 3 and Figure 4In one embodiment, each clamping arm 31 is further provided with a second clamping section 313, which is connected to the opposite ends of the first clamping section 312 along with the flange 311. The second clamping section 313 and the first clamping section 312 are set at an obtuse angle. When the fixed shaft 11 is inserted into the snap ring 30, the two second clamping sections 313 abut tightly against the opposite side walls of the fixed shaft 11. In addition, the distance between the two first clamping sections 312 is set to S, and the diameter of the fixed shaft 11 is set to D. S is, for example, 0.6D to 0.99D, specifically, for example, 0.6D, 0.8D, 0.9D, 0.95D, or 0.99D. When the limiting member 40 is in the pressed position, it can stably clamp and fix the fixed shaft 11, preventing the fixed shaft 11 from coming outward through the gap between the two first clamping sections 312.

[0059] Please see Figure 9 and Figure 10 , Figure 12 and Figure 13 In another embodiment, the limiting member 40 includes a limiting cover, which is detachably snapped onto the mounting portion 20 along the insertion / removal direction f of the fixed shaft 11. Thus, in the case of a compact spatial layout, since the insertion / removal direction of the limiting cover on the mounting portion 20 is the same as that of the fixed shaft 11, it facilitates the individual assembly and disassembly of the limiting cover and the fixed shaft 11.

[0060] Please see Figure 9 and Figure 10 , Figure 12 and Figure 13 In one embodiment, the limiting cover is provided with a first limiting plate 43 that engages with the first mounting plate 21, and two second limiting plates 44 that engage with the two second mounting plates 22 respectively. Both second limiting plates 44 are connected to the first limiting plate 43. Thus, because the first limiting plate 43 engages with the first mounting plate 21, and the two second limiting plates 44 engage with the two second mounting plates 22 respectively, the limiting cover can be stably mounted on the mounting portion 20.

[0061] Of course, as some alternative solutions, at least one of the first limiting plate 43 and the two second limiting plates 44 can be omitted. Alternatively, only the first limiting plate 43 and at least one of the two second limiting plates 44 can be snapped together with the mounting part 20.

[0062] Please see Figure 9 and Figure 10 , Figure 12 and Figure 13In one embodiment, a first locking block 212 is provided on the outer wall of the first mounting plate 21, and a first locking slot 431 corresponding to the first locking block 212 is provided on the first limiting plate 43. The first locking block 212 is engaged in the first locking slot 431. Furthermore, a second locking block 221 is provided on the outer wall of the second mounting plate 22, and a second locking slot 441 corresponding to the second locking block 221 is provided on the second limiting plate 44. The second locking block 221 is engaged in the second locking slot 441. Thus, because the first limiting plate 43 has a first locking slot 431 that engages with the first locking block 212, it is possible to directly observe whether the first locking block 212 is engaged in the first locking slot 431, and disassembly is convenient. Similarly, because the second limiting plate 44 has a second locking slot 441 that engages with the second locking block 221, it is possible to directly observe whether the second locking block 221 is engaged in the second locking slot 441, and disassembly is convenient.

[0063] Please see Figure 3 and Figure 4 or Figure 12 and Figure 13 In one embodiment, the mounting portion 20 further includes a first support portion 24 connected to the first mounting plate 21 and located in the mounting space 23. Furthermore, the first support portion 24 passes through the retaining spring 30, and its top surface supports the fixed shaft 11. Thus, when the fixed shaft 11 is mounted on the mounting portion 20, the top surface of the first support portion 24 supports the fixed shaft 11, and each abutment portion 41 abuts against each clamping arm 31, ensuring that the two clamping arms 31 of the retaining spring 30 maintain tight contact with the opposite sides of the fixed shaft 11, thereby securing the fixed shaft 11 firmly on the mounting portion 20.

[0064] Please see Figure 3 and Figure 4 or Figure 12 and Figure 13 In some embodiments, a concave surface is formed on the top surface of the first support portion 24, including but not limited to a V-shaped surface, an arc-shaped surface, or other regular and irregular shapes, which has a large contact area with the fixed shaft 11 and can achieve a stable installation of the fixed shaft 11.

[0065] Please see Figure 3 and Figure 4 or Figure 12 and Figure 13In some embodiments, the top of the first support portion 24 has abutment surfaces 241 on opposite sides, which are set at acute angles to the insertion / removal direction f. The distance between the two abutment surfaces 241 gradually decreases along the removal direction. Furthermore, the angle formed by the abutment surfaces 241 and the insertion / removal direction is substantially consistent with the angle formed by the second clamping section 313 and the insertion / removal direction; that is, the difference in angle is controlled within, for example, 5°. In other words, the abutment surfaces 241 are substantially parallel to the second clamping section 313 with which they abut. This improves stability and prevents excessive deformation of the retaining spring 30, thus extending its service life.

[0066] Please see Figure 3 and Figure 4 or Figure 12 and Figure 13 In one embodiment, the mounting portion 20 further includes a second support portion 25 connected to the first mounting plate 21 and located in the mounting space 23. The second support portion 25 and the first support portion 24 are spaced apart to form a positioning space 26, and the first connecting arm 32 passes through the positioning space 26. Thus, when the first connecting arm 32 passes through the positioning space 26, the retaining ring 30 can be securely mounted on the mounting portion 20.

[0067] Please see Figure 3 and Figure 4 or Figure 12 and Figure 13 In one embodiment, a first engaging portion 27 is provided on the inner wall of the positioning space 26, and a second engaging portion 321 is provided on the first connecting arm 32 to engage with the first engaging portion 27. Thus, when the first connecting arm 32 is disposed in the positioning space 26, the first engaging portion 27 and the second engaging portion 321 engage with each other, thereby enabling the first connecting arm 32 to be securely installed in the positioning space 26.

[0068] Specifically, the first engaging portion 27 can be located on the side of the first support portion 24 facing the second support portion 25, or on the side of the second support portion 25 facing the first support portion 24. Furthermore, when the first engaging portion 27 is a slot, the second engaging portion 321 is correspondingly a protrusion that engages with the slot; conversely, when the first engaging portion 27 is a protrusion, the second engaging portion 321 is correspondingly a slot that engages with the protrusion.

[0069] Please see Figure 3 and Figure 4 or Figure 12 and Figure 13In one embodiment, the opposite sides of the first support portion 24 form movable intervals 28 with the two second mounting plates 22, and the two clamping arms 31 are respectively inserted into the two movable intervals 28. In this way, the two clamping arms 31 move within their respective movable intervals 28, avoiding severe deformation of the retaining spring 30 under force, which could lead to failure.

[0070] It should be noted that the "installation part 20" can be a part of the "support body 50", that is, the "installation part 20" and the "other parts of the support body 50" are integrally molded; or it can be an independent component that can be separated from the "other parts of the support body 50", that is, the "installation part 20" can be manufactured independently and then combined with the "other parts of the support body 50" to form a whole.

[0071] Modal analysis revealed that the support structure in the relevant technology exhibits resonance at the optical components, which exacerbates the vibration of the optical components.

[0072] Please see Figures 14 to 16 or Figures 17 to 19 Compared to Figures 2 to 7 The difference in the structure shown lies in the addition of a damping element 60. In one embodiment, the support assembly further includes a damping element 60 connected to the limiting member 40. The damping element 60 is connected to the support body 50. Thus, the limiting member 40 not only ensures that the two clamping arms 31 are in close contact with the opposite sides of the fixed shaft 11, but also, due to the connection of the damping element 60, which is connected to the support body 50, the damping element 60 reduces the vibration of the optical element 10 or shifts the resonance position to other parts of the support body 50, thereby reducing the resonance phenomenon of the optical element 10.

[0073] Please see Figures 14 to 16 In one embodiment, the vibration damping member 60 includes a second connecting arm 61, a vibration damping body 62, and an elastic connecting portion 63. The second connecting arm 61 connects the limiting member 40 and the vibration damping body 62, and a gap is provided between the second connecting arm 61 and the support body 50. The vibration damping body 62 is connected to the support body 50 through the elastic connecting portion 63. In this way, the limiting member 40 can transmit the vibration generated at the optical element 10 to the vibration damping body 62 through the second connecting arm 61, and the vibration damping body 62 can transmit the vibration to the support body 50 through the elastic connecting portion 63, thereby realizing the transfer of vibration position and reducing the resonance phenomenon of the optical element 10. In addition, since the vibration damping body 62 is connected to the support body 50 through the elastic connecting portion 63, the abnormal noise caused by the vibration of the vibration damping body 62 can be reduced. Furthermore, since there is a gap between the second connecting arm 61 and the support body 50, it can prevent the second connecting arm 61 from transmitting the vibration to the support body 50, but instead transmit it to the vibration damping body 62, and then to the support body 50.

[0074] Please see Figures 14 to 16 In some embodiments, the limiting member 40, the second connecting arm 61, and the vibration damping body 62 are designed as an integrated structure, including but not limited to being integrally molded by injection molding, specifically as plastic parts.

[0075] Please see Figures 14 to 16 In some embodiments, the second connecting arm 61 is provided with a cutout 611. This cutout 611 reduces the weight of the second connecting arm 61 and transfers the center of gravity and vibration points of the overall structure to the vibration damping body 62, achieving the purpose of resonant source transfer. Furthermore, it weakens the vibration caused by the second connecting arm 61 to the support body 50, increasing the vibration damping effect at the vibration damping body 62.

[0076] Please see Figures 14 to 16 In some embodiments, one side of the elastic connection 63 is, but is not limited to, bonded to the vibration damping body 62, and the other side of the elastic connection 63 is, but is not limited to, snapped to the bracket body 50.

[0077] Please see Figures 14 to 16 In some embodiments, the elastic connection 63 may be configured as a single piece arranged on the bottom surface of the vibration damping body 62, or it may be configured as multiple small pieces arranged, for example, in an array, on the bottom surface of the vibration damping body 62, or it may be configured on the bottom surface of the vibration damping body 62 in other ways.

[0078] Please see Figures 14 to 16 As an example, the bottom wall of the vibration damping body 62 is provided with multiple protrusions 621, and multiple elastic connection parts 63 are provided, with each elastic connection part 63 correspondingly arranged on each protrusion 621.

[0079] Please see Figures 17 to 19 In one embodiment, the vibration damper 60 includes at least one fixed foot 64 connected to the limiting member 40. The support body 50 has a corresponding insertion portion 51 for the fixed foot 64, and the insertion portion 51 has an insertion hole 511. The fixed foot 64 is correspondingly inserted and fixed in the insertion hole 511. Thus, since the vibration damper 60 is fixedly inserted into the insertion hole 511 by the fixed foot 64, the stability of the overall structure of the optical element 10 is improved, and vibration is reduced.

[0080] Please see Figures 17 to 19 In some embodiments, two fixing feet 64 are provided, located on opposite sides of the fixing shaft 11. Correspondingly, two insertion parts 51 are provided, and the two fixing feet 64 are respectively inserted and fixed in the two insertion parts 51.

[0081] Of course, as optional solutions, the vibration damping component 60 in the above embodiments is not mandatory. The bracket body 50 is connected to the windshield via adhesive. By appropriately adjusting and setting the position of the adhesive, the vibration damping effect at the optical element 10 can be improved. Specifically, the adhesive includes, but is not limited to, PU adhesive. Specifically, by identifying the areas on the bracket with excessive vibration amplitude based on the modal analysis diagram, adhesive can be applied to these areas to reduce the vibration at the optical element 10.

[0082] In one embodiment, a windshield assembly includes a bracket assembly of any of the above embodiments, and a windshield (not shown), the bracket assembly being disposed on the inner surface of the windshield.

[0083] The aforementioned windshield assembly, due to the presence of a limiting member 40, which has both a pressing position and a releasing position, allows the limiting member 40 to be in the releasing position when the optical element 10 is mounted on the bracket body 50 or removed. This release position separates each abutment part 41 from the clamping arms 31, allowing the fixing shaft 11 to smoothly push the two clamping arms 31 apart when inserted between them with minimal insertion force, facilitating installation. Similarly, when the fixing shaft 11 is pulled outward from the two clamping arms 31, it smoothly pushes them apart, facilitating disassembly. When the optical element... After the optical element 10 is inserted into the area between the two clamping arms 31, the limiting member 40 is in the pressing position, and each abutting part 41 abuts against each clamping arm 31, so that the two clamping arms 31 are tightly abutted against the opposite sides of the fixed shaft 11. This ensures that the optical element 10 has a small insertion force and a large pull-out force during the assembly process. In addition, under the action of the limiting member 40, the tension of the retaining spring 30 can be kept constant, and the pull-out force between the retaining spring 30 and the fixed shaft 11 can be stably met in the long term. In addition, the interference between the retaining spring 30 and the fixed shaft 11 can be reduced to reduce the insertion force.

[0084] In one embodiment, a vehicle includes a windshield assembly according to any of the above embodiments.

[0085] The aforementioned vehicle, equipped with a limiting member 40, which has both a pressing and a releasing position, allows the limiting member 40 to be in the releasing position when the optical element 10 is mounted on the bracket body 50 or removed. This releases the contact parts 41 from the clamping arms 31, allowing the fixing shaft 11 to push the two clamping arms 31 apart when inserted between them with minimal insertion force, facilitating installation. Similarly, when the fixing shaft 11 is pulled outward from the two clamping arms 31, it also pushes them apart, facilitating disassembly. When the optical element 10... After being inserted into the area between the two clamping arms 31, the limiting member 40 is placed in the pressing position, and each abutting part 41 abuts against each clamping arm 31, so that the two clamping arms 31 are tightly abutted against the opposite sides of the fixed shaft 11. This ensures that the optical element 10 has a small insertion force and a large pull-out force during the assembly process. In addition, under the action of the limiting member 40, the tension of the retaining spring 30 remains unchanged, and the pull-out force between the retaining spring 30 and the fixed shaft 11 is consistently met in the long term. Furthermore, the interference between the retaining spring 30 and the fixed shaft 11 can be reduced to reduce the insertion force.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0088] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
