Description

Technical Field

[0001] The utility model belongs to the technical field of rearview mirror accessories, in particular to a strong-load bearing rearview mirror pin. Background Art

[0002] A car rearview mirror usually includes a base, a rotating shaft mechanism and a rearview mirror mounted on the rotating shaft mechanism. The rotating shaft mechanism is a necessary mechanism to realize the foldable function of the rearview mirror. The rotating shaft mechanism usually includes a rotating (pin) shaft, a spring and a locking mechanism for locking the spring. The rotating shaft is an important accessory in the rotating shaft mechanism.

[0003] The rotating shaft and the base of the rotating shaft are respectively installed on the rearview mirror and the base. When the rearview mirror rubs and collides with other vehicles during driving, the rotating shaft and the base are prone to breakage and damage. When the rotating shaft and the base are broken, the normal use and operation of the rearview mirror itself will be affected, thereby affecting the safety of the car during driving. Utility Model Content

[0004] The purpose of the present invention is to provide a strong load-bearing rearview mirror pin in order to solve the above-mentioned problems.

[0005] The technical solution adopted by the present invention is as follows: a strong load-bearing rearview mirror pin, including a pin body, a reinforcement and a base plate, wherein the pin body and the base plate are an integrally formed structure, the reinforcement is an annular structure, and is placed inside the connection between the pin body and the base plate, and the outer end surface of the bottom of the pin body is circumferentially provided with multiple reinforcement ribs connected to the base plate.

[0006] In a preferred embodiment, the reinforcement is formed as an insert in a mold integrally with the pin body and the base plate.

[0007] In a preferred embodiment, the upper and lower ends of the reinforcement member extend into the pin shaft body and the bottom plate respectively.

[0008] In a preferred embodiment, the cross-section of the reinforcing rib is triangular, and the reinforcing rib is formed as an integral part with the pin body and the base plate.

[0009] In a preferred embodiment, a through-hole is vertically provided between the pin body and the bottom plate.

[0010] In a preferred embodiment, the bottom of the base plate is inwardly recessed to form at least one limiting groove.

[0011] In a preferred embodiment, a positioning groove is formed by punching inwardly on the outer wall of the pin shaft body.

[0012] In a preferred embodiment, the top of the pin shaft body is a frustum that is narrow at the top and wide at the bottom.

[0013] In a preferred embodiment, the hardness of the reinforcement is greater than the hardness of the pin body and the base plate.

[0014] To sum up, due to the adoption of the above-mentioned technical solution, the beneficial effects of the present invention are: reinforcement parts are embedded inside the pin shaft body and the base plate, and multiple groups of reinforcement ribs are designed on the periphery of the pin shaft body and the base plate. With relatively little additional cost, the bearing strength between the pin shaft body and the base plate can be improved, and when encountering external collisions, it is less likely to cause breakage and damage, thereby increasing the service life of the rearview mirror, which is worthy of promotion.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Reference Figure 1-2 , a strong load-bearing rearview mirror pin, including a pin body 1, a reinforcement 5 and a base plate 2, wherein the pin body 1 and the base plate 2 are an integrally formed structure, the reinforcement 5 is a ring-shaped structure, and is placed inside the connection between the pin body 1 and the base plate 2, and the reinforcement 5 is molded as an insert in the mold with the pin body 1 and the base plate 2, and the upper and lower ends of the reinforcement 5 extend into the pin body 1 and the base plate 2 respectively. The hardness of the reinforcement 5 is greater than that of the pin body 1 and the base plate 2. The reinforcement 5 is embedded in the pin body 1 and the base plate 2, which can improve the bearing strength between the pin body and the base plate with less additional cost and weight. When encountering an external collision, the connection between the pin body 1 and the base plate 2 is not prone to breakage and damage, thereby increasing the service life of the rearview mirror.

[0020] The pin body 1 and the base plate 2 are preferably made of zinc alloy material, and the reinforcement 5 is preferably made of steel material, or other materials with better hardness than steel material, which is not limited here.

[0021] Furthermore, a plurality of reinforcing ribs 3 connected to the bottom plate 2 are circumferentially provided on the outer end surface of the bottom of the pin shaft body 1. The cross-section of the reinforcing ribs 3 is triangular. The reinforcing ribs 3, the pin shaft body 1 and the bottom plate 2 are integrally formed. The plurality of reinforcing ribs 3 designed circumferentially can further increase the connection strength between the pin shaft body 1 and the bottom plate 2.

[0022] There are at least three reinforcing rib positions 3, which is not limited here.

[0023] Furthermore, a through-hole 8 is vertically provided between the pin body 1 and the base plate 2 , and the through-hole 8 is designed to meet the wiring operation of the rearview mirror part.

[0024] Furthermore, the bottom of the base plate 2 is recessed inward to form at least one limiting groove 4, and a limiting block (not shown in the figure) corresponding to the limiting groove 4 is reserved on the rearview mirror base, which can assist in limiting the installation position of the base plate 2, thereby improving the installation accuracy of the base plate 2.

[0025] Furthermore, a positioning groove 6 is punched inward on the outer wall of the pin shaft body 1, and the positioning groove 6 can be connected to a spring locking mechanism (not shown in the figure). Since the positioning groove 6 is punched by a stamping equipment, the wall thickness of the positioning groove 6 is basically the same as that of the pin shaft body 1, and will not affect the bearing strength of the pin shaft body 1 at the positioning groove 6.

[0026] Furthermore, the top of the pin body 1 is a frustum portion 7 that is narrow at the top and wide at the bottom. The frustum portion 7 is designed to facilitate the installation operation of the retaining spring (not shown in the figure) in the spring locking mechanism.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
