Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to a flexible folding adaptive rearview mirror composite bracket. Background Technology

[0002] In practical applications of special vehicles, vehicle-mounted equipment brackets often need to have two states: deployed for operation and folded for storage. For example, antenna brackets for military reconnaissance vehicles, work platform brackets for engineering vehicles, and equipment mounting brackets for rescue vehicles all need to be kept folded while driving to reduce height and wind resistance, and deployed to a vertical state to provide stable support during operation.

[0003] Existing folding mechanisms mostly employ complex structures such as linkage mechanisms, gear racks, or hydraulic transmissions, resulting in numerous parts and requiring high precision in their assembly. Prolonged use on bumpy roads can easily lead to component wear and excessive clearances, causing the mechanism to jam or wobble abnormally, and even posing a safety hazard. The complex structure also increases manufacturing costs and assembly difficulty, hindering mass production.

[0004] To address these issues, we offer a flexible folding adaptive rearview mirror composite bracket. Utility Model Content

[0005] The purpose of this utility model is to provide a flexible folding adaptive rearview mirror composite bracket. Through the cooperation of the front assembly, the rear assembly and the threaded pin, it solves the problems of the complex structure of the existing folding mechanism, which is prone to damage during long-term bumpy use. At the same time, the complicated structure increases the processing cost and assembly difficulty, which is not conducive to mass production.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a flexible folding adaptive rearview mirror composite bracket, comprising a front assembly, a rear assembly, and a threaded pin. The front assembly and the rear assembly are movably connected by the threaded pin. A connecting seat is fixedly connected to one side of the front assembly. The inner cavity of the connecting seat has a receiving groove. Both the upper and lower ends of the inner cavity of the receiving groove have vertical conical holes. Both the upper and lower ends of the inner cavity of the front assembly have vertical conical holes. The vertical conical holes are connected. One side of the rear assembly has a mounting hole. The other side of the rear assembly has a rotating shaft. The surface of the rotating shaft has a vertical conical hole and a horizontal conical hole, which intersect at an angle.

[0008] The present invention is further configured such that both the front assembly and the rear assembly adopt a hollow design. The hollow design of the front assembly and the rear assembly effectively reduces the overall weight and saves material costs while ensuring the structural strength of the bracket, and facilitates the arrangement of internal cable components.

[0009] The present invention is further configured such that the connecting seat is fixedly connected to one end of the inner cavity of the front assembly, and the rotating shaft is fixedly connected to one end of the inner cavity of the rear assembly. This layout makes the connection structure more compact, the force distribution more uniform, and improves the overall rigidity and stability of the bracket.

[0010] The present invention is further configured such that the rotating shaft is inserted into the inner cavity of the receiving groove, and an opening is provided on one side of the bottom of the rear assembly. The rotating shaft is inserted into the inner cavity of the receiving groove to ensure that the front assembly can rotate flexibly around the rotating shaft to achieve the folding function.

[0011] The present invention is further provided that the bottom of the threaded pin is provided with a hexagonal countersunk hole, which facilitates installation and disassembly using a hexagonal wrench, thereby improving the ease of operation.

[0012] The present invention is further configured such that the inner cavities of the vertical conical hole one, vertical conical hole two, vertical conical hole three, and horizontal conical hole are all provided with internal threads, and the surface of the threaded pin is provided with external threads that cooperate with the internal threads. The internal threads of the inner cavities of the vertical conical hole one, vertical conical hole two, vertical conical hole three, and horizontal conical hole cooperate with the external threads on the surface of the threaded pin to form a reliable threaded connection, which enhances the connection strength and locking effect between the components and ensures that the bracket will not loosen during use.

[0013] The present invention is further configured such that the inner cavity of the mounting hole is fixedly connected to the vehicle body by bolts. This fixing method is simple and reliable, and can securely install the bracket on the vehicle body, ensuring the stability of the rearview mirror during vehicle operation.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model significantly reduces the number of parts through the core design of connecting the front assembly and the rear assembly via threaded pins. Vertical conical hole one and vertical conical hole two are connected, and vertical conical hole three on the rear assembly shaft crosses with the horizontal conical hole. With the engagement of the external thread of the threaded pin and the internal thread of each conical hole, a multi-directional positioning and locking structure is formed. This design not only reduces the requirements for machining accuracy and assembly difficulty, facilitating mass production, but also effectively avoids the problems of component wear and excessive clearance caused by complex structures under bumpy road conditions. It significantly improves the stability of the bracket in long-term use, reduces the risk of jamming or abnormal shaking, and enhances overall reliability.

[0016] 2. The structure of the rotating shaft insertion connecting seat receiving groove of this utility model allows the rear assembly to rotate around the rotating shaft, realizing flexible switching between folded storage and unfolded working states. The threaded pin can be selectively inserted into the vertical conical hole one, vertical conical hole two, vertical conical hole three, and horizontal conical hole at different positions according to usage requirements. Utilizing the double locking effect of the conical surface fit of the conical hole and the threaded connection, multi-angle adaptive fixing is achieved. This design allows the bracket to adjust the installation angle and folding state of the rearview mirror according to actual working conditions, which not only meets the needs of reducing height and wind resistance when driving, but also provides stable support during operation, improving the practicality and applicability of the bracket.

[0031] The working principle of this utility model is as follows: When the rearview mirror needs to be used, the front assembly 1 is rotated around the pivot 9 to the unfolded state. At this time, the vertical conical hole 1 6, the vertical conical hole 2 7, and the vertical conical hole 3 10 are connected. Then, the threaded pin 3 is inserted into the inner cavity of the vertical conical hole 1 6, the vertical conical hole 2 7, and the vertical conical hole 3 10. By using the engagement of the external thread of the threaded pin 3 with the internal thread of the conical hole, the front assembly 1 and the rear assembly 2 are fixedly connected, realizing the unfolding and angle fixation of the rearview mirror bracket, providing stable support for the rearview mirror. When the rearview mirror needs to be folded while the vehicle is in motion, the threaded pin 3 is unscrewed, and the front assembly 1 is rotated around the pivot 9. At this time, the vertical conical hole 1 6, the vertical conical hole 2 7, and the horizontal conical hole 11 are connected. Then, the threaded pin 3 is inserted back to realize the folding and storage function.
