Description

Technical Field

[0001] The present invention relates to the technical field of vehicle accessories, and in particular to a rearview mirror device and a car. Background Art

[0002] Rearview mirrors reflect what's happening behind, to the sides, and below the vehicle, allowing the driver to indirectly see what's happening in those areas. They act as a "second pair of eyes," expanding the driver's field of vision. To enhance vehicle functionality, the exterior rearview mirrors are equipped with features like heating and blind spot monitoring indicators.

[0003] In the related art, in order to equip the rearview mirror with functions such as heating and blind spot monitoring indicators, it is necessary to lead the electrical connection harnesses of these functional components from the edge of the lens to the rearview mirror assembly harness. However, to meet the field of view requirements of different drivers, rearview mirrors are generally designed to be angle-adjustable to provide the driver and passengers with a viewing angle adjustment function. However, when the lens is adjusted up, down, left, and right, it will drive the movement of the harness, so a long active harness is reserved for the harness to move with the lens. However, if it moves all at once, the harness position will become uncontrollable, and problems such as harness entanglement, jamming, and abnormal noises often occur. These problems affect the normal use of the heating and blind spot monitoring indicators, hinder lens adjustment, and even prevent the driver from using the rearview mirror normally. Summary of the Invention

[0004] Regarding the relevant 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 the lens adjustment to be blocked, and even makes the driver unable to use the rearview mirror normally.

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

[0030] Regarding the relevant 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 the lens adjustment to be blocked, 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 frame assembly 1 and a lens assembly 2; wherein,

[0032] The frame assembly 1 is connected to the vehicle and has a conductive layer 11 attached to its interior for electrical connection to the rearview mirror assembly wiring harness. The lens assembly 2 is housed within the frame assembly 1 and has a conductive support assembly 3 attached to it. The support assembly 3 abuts the interior of the frame assembly 1 and maintains contact with the conductive layer 11.

[0033] It should be noted that in related art rearview mirrors, the lens assembly 2 is typically mounted inside the frame assembly 1 via a drivable reversing device. The lens assembly 2 also incorporates features such as heating and a blind spot monitoring indicator. Therefore, the lens assembly 2 requires a wiring harness electrically connected to the main harness of the frame assembly 1. Reversing the lens assembly 2 to adjust the angle causes the wiring harness to move, creating a risk of entanglement.

[0034] It is worth noting that the support assembly 3 in this application does not drive the lens assembly 2 to change direction. Instead, it abuts against the frame assembly 1 after the lens assembly 2 rotates to the appropriate rear 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 vibrations or collisions. In addition, by providing a conductive support arm, the support arm treatment at the rear of the lens improves the stability of the lens. The support assembly 3 replaces the traditional wire conductive solution, effectively preventing the problem of entanglement, abnormal noise and jamming of the wire harness inside the rearview mirror.

[0035] In some optional embodiments, 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, and the conductive roller 32 abuts against the conductive layer 11 and 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 conductivity, 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.

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

[0039] A support arm 311 is mounted inside the lens assembly 2. An elastic member 312 is connected to the support arm 311 at one end and to the conductive roller 32 at the other end. 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 lens adjustment, the support member of the lens assembly 2 generally maintains contact with the inner side of the frame assembly 1 to prevent jitter during driving. However, due to assembly precision or the influence of vehicle vibration, it is difficult for the support member and frame assembly 1 to maintain contact, and the support member and frame assembly 1 often lose contact, which in turn leads to lens jitter, abnormal noise, or excessive contact (difficulty in lens adjustment). In this application, a support arm 311 with an elastic member 312 is used to replace the traditional support member. The elastic member 312 is always in a compressed state to apply a pressing force to the conductive roller 32, solving the lens jitter and adjustment jamming problems encountered in traditional solutions.

[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 on the inner side of 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 slidingly cooperate 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 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 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, the first bosses 411 being arranged on a side close to the edge of the frame assembly 1, the second bosses 412 being arranged on a side away from the edge of the frame assembly 1, and the conductive layer 11 being attached to the surface of the second bosses 412.

[0048] It should be noted that in related art, to enhance user convenience, a lens memory function is often added to rearview mirrors, allowing drivers to find the lens position that suits them. This function requires a lens commutator with a memory function, which is a relatively costly solution. In this application, the multiple bosses 41 are divided into a second boss 412, which is provided with a conductive layer 11, and a first boss 411 for memory positioning. The conductive roller 32 slides only on the second boss 412, maintaining electrical connection. The first boss 411, on the other hand, is used by the user to visually 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, firmly clamped, and plays a supporting role for the lens, effectively avoiding the problem of lens shaking. The conductive roller 32 contacts the conductive paper on the second boss 412 of the frame to achieve electrical 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 card slot 42 position. When adjusting, the user can quickly adjust to a position that suits him / herself (memorize the lens position that suits him / herself corresponds to which boss 41, and can quickly adjust to his / her own position the next time he / she adjusts), 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's worth noting that conductive paper exhibits excellent chemical and thermal stability, maintaining stable physical and chemical properties in a variety of harsh environments. It's also resistant to chemical corrosion and maintains stable performance at high temperatures. Its excellent electrical conductivity and low contact resistance significantly reduce internal battery consumption and improve the efficiency of energy storage devices. Furthermore, conductive paper possesses a certain mechanical strength, extending the lifespan of electrodes. It also offers low manufacturing costs and a high cost-effectiveness.

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

[0053] The frame assembly 1 is connected to the vehicle and has a conductive layer 11 attached to its interior for electrical connection to the rearview mirror assembly wiring harness. The lens assembly 2 is housed within the frame assembly 1 and has a conductive support assembly 3 attached to it. The support assembly 3 abuts the interior of the frame assembly 1 and maintains contact with the conductive layer 11.

[0054] It should be noted that in related art rearview mirrors, the lens assembly 2 is typically mounted inside the frame assembly 1 via a drivable reversing device. The lens assembly 2 also incorporates features such as heating and a blind spot monitoring indicator. Therefore, the lens assembly 2 requires a wiring harness electrically connected to the main harness of the frame assembly 1. Reversing the lens assembly 2 to adjust the angle causes the wiring harness to move, creating a risk of entanglement.

[0055] It is worth noting that the support assembly 3 in this application does not drive the lens assembly 2 to change direction. Instead, it abuts against the frame assembly 1 after the lens assembly 2 rotates to the appropriate rear 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 vibrations or collisions.

The support assembly 3 replaces the traditional wire conductive solution, effectively preventing the problem of entanglement, abnormal noise and jamming of the wire harness inside the rearview mirror.

[0056] In some optional embodiments, Figure 2 As shown, the support assembly 3 includes: a support body 31 and a conductive roller 32; wherein,

[0057] The support body 31 has one end connected to the lens assembly 2. The conductive roller 32 is connected to the support body 31, and the conductive roller 32 abuts against the conductive layer 11 and can slide along the inner side of the frame assembly 1.

[0058] It is worth noting that the connection between the support body 31 and the conductive roller 32 can achieve electrical conductivity, 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.

[0059] Furthermore, the support body 31 includes: a support arm 311 and an elastic member 312; wherein,

[0060] A support arm 311 is mounted inside the lens assembly 2. An elastic member 312 is connected to the support arm 311 at one end and to the conductive roller 32 at the other end. 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 lens adjustment, the support member of the lens assembly 2 generally maintains contact with the inner side of the frame assembly 1 to prevent jitter during driving. However, due to assembly precision or the influence of vehicle vibration, it is difficult for the support member and frame assembly 1 to maintain contact, and the support member and frame assembly 1 often lose contact, which in turn leads to lens jitter, abnormal noise, or excessive contact (difficulty in lens adjustment). In this application, a support arm 311 with an elastic member 312 is used to replace the traditional support member. The elastic member 312 is always in a compressed state to apply a pressing force to the conductive roller 32, solving the lens jitter and adjustment jamming problems encountered in traditional solutions.

[0062] 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 .

[0063] In some preferred embodiments, a positioning component 4 is provided on the inner side of 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 .

[0064] 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 .

[0066] In some specific implementations, a groove 12 is provided on the inner side of the frame assembly 1 , and the boss 41 is received in the groove 12 .

[0067] It is understandable that a groove 12 is designed inside the 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.

[0068] Preferably, the plurality of bosses 41 include a plurality of first bosses 411 and a plurality of second bosses 412, the first bosses 411 being arranged on a side close to the edge of the frame assembly 1, the second bosses 412 being arranged on a side away from the edge of the frame assembly 1, and the conductive layer 11 being attached to the surface of the second bosses 412.

[0072] It is worth noting that conductive paper has good chemical 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 the cost performance is high.
