Description

[0002] The vehicle rearview mirror reflects the situation behind, to the side and below the vehicle, allowing the driver to indirectly see the situation in these locations.

[0003] In the related art, in order to equip the rearview mirror with functions such as heating and blind spot monitoring indicator lights, it is necessary to lead the electrical connection harness of these functional components from the edge of the lens to the rearview mirror assembly harness.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] With regard to the related technologies, the electrical connection harness of the rearview mirror often has problems such as harness entanglement, jamming and abnormal noise, which affects the normal use of the heating and blind spot monitoring indicator lights, causes obstruction of lens adjustment, and even makes the driver unable to use the rearview mirror normally.

[0031] First, as Figure 1 and Figure 4 As shown, a rearview mirror device comprises: a mirror frame assembly 1 and a lens assembly 2; wherein,

[0032] The frame assembly 1 is used to be connected to the vehicle, and a conductive layer 11 electrically connected to the rearview mirror assembly wiring harness is attached to the inner side of the frame assembly 1. The lens assembly 2 is accommodated in the frame assembly 1, and a conductive support component 3 is provided on the lens assembly 2, and the support component 3 abuts against the inner side of the frame assembly 1, and the support component 3 can maintain contact with the conductive layer 11.

[0033] It should be noted that in the related art, the lens assembly 2 of the rearview mirror is generally installed on the inner side of the frame assembly 1 through a drivable reversing device, and the lens assembly 2 is also integrated with functions such as assembly heating and blind spot monitoring indicator light. Therefore, the lens assembly 2 needs to be provided with a wiring harness to be electrically connected to the main harness of the frame assembly 1. When the lens assembly 2 is reversing to adjust the angle, the wiring harness will be driven to move, and there is a risk of the wiring harness being entangled.

[0034] It is worth noting that the support assembly 3 in the present application does not drive the lens assembly 2 to change direction, but abuts against the frame assembly 1 after the lens assembly 2 rotates to a suitable position, so that after the lens assembly 2 is fixed at an angle, it will not shake relative to the frame assembly 1 when subjected to external vibration or collision. In addition to improving the stability of the lens by providing a conductive support arm, the support assembly 3 replaces the traditional wire conductive solution, effectively avoiding the problems of entanglement, abnormal noise and jamming of the wire harness inside the rearview mirror.

[0035] In some optional implementations, such as Figure 2 As shown, the support assembly 3 includes: a support body 31 and a conductive roller 32; wherein,

[0036] The support body 31 has one end connected to the lens assembly 2. The conductive roller 32 is connected to the support body 31, the conductive roller 32 abuts against the conductive layer 11, and the conductive roller 32 can slide along the inner side of the frame assembly 1.

[0037] It is worth noting that the connection between the support body 31 and the conductive roller 32 can achieve electrical conduction, thereby replacing the wiring harness. At the same time, during the angle adjustment process of the lens assembly 2, the conductive roller 32 moves along the inner side of the lens assembly 2 accordingly.

[0038] Furthermore, the support body 31 includes: a support arm 311 and an elastic member 312; wherein,

[0039] The support arm 311 is installed inside the lens assembly 2. The elastic member 312 has one end connected to the support arm 311 and the other end connected to the conductive roller 32. The elastic member 312 is used to drive the conductive roller 32 to abut against the conductive layer 11 of the frame assembly 1. Optionally, the elastic member 312 can be a spring.

[0040] It is worth noting that during the lens adjustment process, the support member of the lens assembly 2 is generally in contact with the inner side of the frame assembly 1 to prevent shaking during driving. However, due to the assembly accuracy or the vibration of the vehicle itself, it is difficult for the support member and the frame assembly 1 to maintain contact, and the support member and the frame assembly 1 often fail to contact, which leads to lens shaking, abnormal noise or excessive contact (difficult lens adjustment) and other faults. In the present application, a support arm 311 with an elastic member 312 is used to replace the traditional support member, and the elastic member 312 is used to apply a pressing force to the conductive roller 32 in a compressed state, which solves the lens shaking and adjustment jamming problems in the traditional solution.

[0041] Furthermore, a bearing bush 33 is provided at the end of the elastic member 312 , and the bearing bush 33 is connected to the conductive roller 32 .

[0042] In some preferred embodiments, a positioning component 4 is provided inside the frame assembly 1 , a conductive layer 11 is attached to the positioning component 4 , and the positioning component 4 is in sliding cooperation with the conductive roller 32 .

[0043] It is worth noting that the conductive roller 32 slides along the area where the conductive layer 11 is laid, and the laying range of the conductive layer 11 is associated with the adjustable angle of the lens assembly 2 .

[0044] In some specific implementations, such as Figure 3 As shown, the positioning component 4 includes: a plurality of bosses 41 arranged side by side, which are arranged on the inner side of the frame assembly 1, the bosses 41 are slidably matched with the conductive roller 32, and a slot 42 for engaging with the conductive roller 32 is formed between two adjacent bosses 41.

[0045] In some specific implementations, a groove 12 is provided on the inner side of the lens frame assembly 1 , and the boss 41 is received in the groove 12 .

[0046] It is understandable that a groove 12 is designed inside the lens frame assembly 1, and a semi-cylindrical boss 41 is designed in the groove 12. The boss 41 is not higher than the groove 12 to prevent water and dust from entering the boss 41 and affecting the conductive effect.

[0047] Preferably, the plurality of bosses 41 include a plurality of first bosses 411 and a plurality of second bosses 412, wherein the first bosses 411 are arranged on a side close to an edge of the frame assembly 1, and the second bosses 412 are arranged on a side away from an edge of the frame assembly 1, and the conductive layer 11 is attached to the surface of the second bosses 412.

[0048] It should be noted that in order to switch the user's convenience, the related art often adds a lens memory function to the rearview mirror to facilitate the driver to find the lens position suitable for himself. This function requires a lens commutator with a memory function, but this solution is relatively expensive. In this application, the multiple bosses 41 are divided into a second boss 412 with a conductive layer 11 and a first boss 411 for memory positioning. The conductive roller 32 only slides on the second boss 412 to maintain electrical connection. The first boss 411 is used for the user to observe and indicate the lens position and adjust the lens assembly 2 according to the memory position.

[0049] Furthermore, the bosses 41 of the present application are arranged side by side. When the lens assembly 2 rotates, the conductive roller 32 slides between the bosses 41. When the lens is adjusted to an angle, the conductive roller 32 is clamped between the two bosses 41, and the clamping is firm, which provides support for the lens and effectively avoids the shaking problem of the lens. The conductive roller 32 contacts the conductive paper on the second boss 412 of the frame to achieve conductivity between the lens and the frame, avoiding the abnormal noise and jamming problems caused by the use of a wiring harness. When observing the lens from the outside, it can be clearly seen that the lens is in the corresponding position of the card slot 42. The user can quickly adjust it to a position suitable for himself when adjusting (memorize the lens position suitable for himself corresponding to which boss 41, and can quickly adjust it to his own position the next time he adjusts it), simplifying the memory function of the rearview mirror and saving costs.

[0050] In some optional implementations, the conductive layer 11 is conductive paper.

[0051] It is worth mentioning that conductive paper has good chemical stability and thermal stability, can maintain stable physical and chemical properties in various harsh environments, is not easily corroded by chemical substances, and can maintain stable performance in high temperature environments. Conductive paper has good conductivity and low contact resistance, which can greatly reduce the internal consumption of batteries and improve the efficiency of energy storage devices. Furthermore, conductive paper has a certain mechanical strength, which increases the service life of the electrode. At the same time, its manufacturing cost is low and cost-effective.

[0052] In a second aspect, the present application provides an active safety device for a vehicle, which includes: a rearview mirror device, which includes: a mirror frame assembly 1 and a lens assembly 2; wherein,

[0053] The frame assembly 1 is used to be connected to the vehicle, and a conductive layer 11 electrically connected to the rearview mirror assembly wiring harness is attached to the inner side of the frame assembly 1. The lens assembly 2 is accommodated in the frame assembly 1, and a conductive support component 3 is provided on the lens assembly 2, and the support component 3 abuts against the inner side of the frame assembly 1, and the support component 3 can maintain contact with the conductive layer 11.

Therefore, the lens assembly 2 needs to be provided with a wiring harness to be electrically connected to the main harness of the frame assembly 1. When the lens assembly 2 is reversing to adjust the angle, the wiring harness will be driven to move, and there is a risk of the wiring harness being entangled.

The elastic member 312 is used to drive the conductive roller 32 to abut against the conductive layer 11 of the frame assembly 1. Optionally, the elastic member 312 can be a spring.

[0061] It is worth noting that during the lens adjustment process, the support member of the lens assembly 2 is generally in contact with the inner side of the frame assembly 1 to prevent shaking during driving.

In the present application, multiple bosses 41 are divided into a second boss 412 with a conductive layer 11 and a first boss 411 for memory positioning. The conductive roller 32 only slides on the second boss 412 to maintain electrical connection. The first boss 411 is used for the user to observe and indicate the position of the lens, and adjust the lens assembly 2 according to the memory position.
