Description

Technical Field

[0001] This utility model belongs to the field of vehicle parts technology and relates to a rearview mirror. Background Technology

[0002] Traditional rearview mirrors in vehicles (such as motorcycles and electric bikes) typically consist of a mirror body, a fixed handlebar, and supporting connectors, with their core function being simply to provide rear visibility. As users' demands for driving safety and intelligence increase, more and more scenarios require the installation of sensor lights (such as turn signals, night warning lights, and obstacle sensors) on rearview mirrors to enhance driving safety through visual cues. However, traditional rearview mirrors have significant drawbacks: their handlebar mounting structure and supporting connectors are mostly solid or non-through designs, making internal wiring impossible. Forcing external wiring not only damages the overall aesthetics but also easily leads to wear and breakage due to exposed cables. Furthermore, the wiring process interferes with the mirror's angle adjustment (e.g., pulling on the cable during rotation or twisting), making it difficult to stably configure electrical components such as sensor lights. Therefore, the structural design of traditional rearview mirrors can no longer meet the needs of intelligent function expansion, necessitating a rearview mirror that allows for internal wiring without affecting the adjustment function.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a rearview mirror device for electric vehicles [application number: 201510105981.0], which includes a mirror body, a mirror rod, and a handlebar, which are connected sequentially. The mirror body and the mirror rod are hinged together. The key feature is that a limiting ring seat is fixedly connected to the handlebar, and the mirror rod passes through the limiting ring seat and is fixed to the handlebar. However, this solution still has the drawbacks of not being able to provide wiring and implementing sensor light configuration. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems by providing a rearview mirror.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rearview mirror includes a rearview mirror body and a rearview mirror handlebar. A supporting connecting rod is provided between the rearview mirror body and the rearview mirror handlebar. The supporting connecting rod is rotatably engaged with the rearview mirror handlebar. At the end of the supporting connecting rod away from the rearview mirror handlebar, a ball joint connecting assembly extends into the back of the rearview mirror body and is torsionally connected to the rearview mirror body. The rearview mirror handlebar has a first hollow wiring structure, the supporting connecting rod has a second hollow wiring structure, and the ball joint connecting assembly has a third hollow wiring structure. The first, second, and third hollow wiring structures are interconnected.

[0007] In one of the aforementioned rearview mirrors, the first hollow wiring structure includes a hollow screw disposed within the rearview mirror handlebar, wherein the external thread of the hollow screw is screwed into the internal thread of the rearview mirror handlebar, and the hollow screw has a first wiring chamber inside.

[0008] In one of the aforementioned rearview mirrors, the hollow screw extends beyond the handlebars of the rearview mirror and forms a screwed step with the handlebars.

[0009] In the aforementioned rearview mirror, the supporting connecting rod includes a supporting connecting bent rod disposed between the rearview mirror body and the rearview mirror handlebar, and a rotating connecting handle is provided between the supporting connecting bent rod and the rearview mirror handlebar, and the supporting connecting bent rod and the rotating connecting handle are rotatably engaged.

[0010] In the aforementioned rearview mirror, the rotating connecting handle is composed of a connecting cylinder, a limiting sleeve, and a limiting nut. The connecting cylinder, the limiting sleeve, and the limiting nut form an inwardly recessed rotating annular groove. The supporting connecting rod is rotatably engaged with the rotating annular groove, and both sides of the supporting connecting rod are tightly attached to the limiting sleeve and the limiting nut, respectively.

[0011] In the aforementioned rearview mirror, the connecting cylinder has a wiring connection cavity and a connection opening inside. One end of the connection opening is connected to the first wiring cavity, and the other end is connected to the second hollow wiring structure.

[0012] In one of the aforementioned rearview mirrors, the second hollow wiring structure includes a second wiring chamber disposed within a supporting connecting rod, and a side cover strip is provided on the side of the supporting connecting rod to engage with the supporting connecting rod.

[0013] In one of the rearview mirrors described above, the ball joint connection assembly includes a ball joint connecting rod and a connecting ball joint disposed at the head of a supporting connecting rod. The tail of the ball joint connecting rod is inserted into the supporting connecting rod, and the connecting ball joint is twistedly connected to the rearview mirror body.

[0014] In one of the aforementioned rearview mirrors, the third hollow wiring structure includes a third wiring chamber disposed within a ball joint connecting rod and a ball joint opening connected within a ball joint, wherein the third wiring chamber is connected to the second wiring chamber.

[0015] In the aforementioned rearview mirror, a ball-head fixing backplate is installed on the back of the rearview mirror body. The ball-head fixing backplate is fixed to the rearview mirror body by bolts or screws. A mirror wiring space is provided inside the rearview mirror body, and the ball-head opening is connected to the mirror wiring space.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. In use, this utility model achieves cable concealment and sensor light function by setting a first hollow wiring structure, a second hollow wiring structure and a third hollow wiring structure in the rearview mirror handle, the support connecting rod and the ball joint connecting assembly, and the three are connected to form a complete internal wiring channel.

[0018] 2. This utility model features an independent design of wiring structure and rotation and torsion adjustment structure. The supporting connecting rod can rotate relative to the rearview mirror handlebar, and the ball joint connecting component can twist relative to the rearview mirror body. During multi-angle adjustment, the cable is not pulled or squeezed, ensuring the stable operation of electrical components.

[0019] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1-6As shown, a rearview mirror includes a rearview mirror body 1 and a rearview mirror handle 2. A supporting connecting rod 3 is provided between the rearview mirror body 1 and the rearview mirror handle 2. The supporting connecting rod 3 is rotatably engaged with the rearview mirror handle 2. A ball joint connecting assembly 4 is provided at the end of the supporting connecting rod 3 away from the rearview mirror handle 2, extending into the back of the rearview mirror body 1 and being torsionally connected to the rearview mirror body 1. A first hollow wiring structure 5 is provided inside the rearview mirror handle 2. A second hollow wiring structure 6 is provided inside the supporting connecting rod 3. A third hollow wiring structure 7 is provided inside the ball joint connecting assembly 4. The first hollow wiring structure 5, the second hollow wiring structure 6, and the third hollow wiring structure 7 are interconnected.

[0029] In this embodiment, the supporting connecting rod 3 is located between the rearview mirror body 1 and the rearview mirror handlebar 2. One end of the rod is rotatably engaged with the rearview mirror handlebar 2, and the other end is connected to the rearview mirror body 1 through the ball joint connecting assembly 4. The ball joint connecting assembly 4 can twist relative to the rearview mirror body 1. At the same time, the first hollow wiring structure 5 in the rearview mirror handlebar 2, the second hollow wiring structure 6 in the supporting connecting rod 3, and the third hollow wiring structure 7 in the ball joint connecting assembly 4 are connected to form a complete internal wiring channel from the rearview mirror handlebar 2 to the rearview mirror body 1. The rearview mirror can be adjusted at multiple angles (to meet the different user vision needs) through "rotational engagement + twisting engagement". At the same time, the connected hollow wiring structure solves the problem of traditional rearview mirrors being unable to provide wiring, providing a power supply / signal transmission channel for electrical components such as sensor lights, and realizing the hidden cable layout and sensor light function.

[0030] Combination Figure 1-6 As shown, the first hollow wiring structure 5 includes a hollow screw 8 disposed in the rearview mirror handlebar 2, the external thread of the hollow screw 8 being screwed into the internal thread of the rearview mirror handlebar 2, and the hollow screw 8 having a first wiring chamber 9.

[0031] Specifically, the hollow screw 8 has external threads on its outer surface, and the rearview mirror handlebar 2 has internal threads on its inner wall. The two are fixed together by threaded connection. The hollow screw 8 has a hollow first wiring chamber 9 inside, which serves as the first channel for the cable from the vehicle to the rearview mirror (the vehicle cable can pass through the first wiring chamber 9 from the tail of the hollow screw 8). The threaded connection between the hollow screw 8 and the rearview mirror handlebar 2 not only achieves a stable connection between the handlebar and the vehicle (by transmitting fixing force through the screw), but also provides a hidden entry point for the cable through the first wiring chamber 9, solving the problem of traditional handlebars being unable to be wired due to their solid design. At the same time, the threaded connection makes it easy to adjust the fixing angle of the handlebar during installation.

[0032] The hollow screw 8 extends to the outside of the rearview mirror handlebar 2 and forms a screwed step with the rearview mirror handlebar 2.

[0033] In this embodiment, the screw-in step can fit against the edge of the vehicle mounting hole and achieve double fixation with the nut (vehicle side) - the screw-in step abuts against the vehicle mounting surface, and the nut locks the hollow screw 8 from the inside of the vehicle, which greatly improves the stability of the connection between the rearview mirror handle 2 and the vehicle and avoids loosening caused by driving vibration; at the same time, the step structure also provides operating space for the cable to be inserted (from the tail of the screw to the first wiring chamber 9).

[0034] Combination Figure 2 , Figure 3 As shown, the supporting connecting rod 3 includes a supporting connecting bent rod 10 disposed between the rearview mirror body 1 and the rearview mirror handle 2. A rotating connecting handle 11 is provided between the supporting connecting bent rod 10 and the rearview mirror handle 2, and the supporting connecting bent rod 10 and the rotating connecting handle 11 are rotatably engaged.

[0035] In this embodiment, the supporting connecting rod 10 is an arc-shaped rod (to fit the vehicle installation space and avoid interference with other components). One end of it is engaged with the rotating connecting handle 11, and the other end is connected to the ball head connecting assembly 4. The rotating connecting handle 11 is fixed on the hollow screw 8 of the rearview mirror handle 2, and the supporting connecting rod 10 can rotate freely around the rotating connecting handle 11.

[0036] The rotating connecting handle 11 is composed of a connecting cylinder 12, a limiting sleeve 13, and a limiting nut 14. The connecting cylinder 12, the limiting sleeve 13, and the limiting nut 14 form an inwardly recessed rotating annular groove. The supporting connecting rod 10 is rotatably engaged with the rotating annular groove, and both sides of the supporting connecting rod 10 are tightly attached to the limiting sleeve 13 and the limiting nut 14, respectively.

[0037] In this embodiment, one end of the connecting cylinder 12 is fixed to the hollow screw 8 (e.g., by screwing or welding), the limiting sleeve 13 is fitted onto the middle of the connecting cylinder 12 (with an interference fit), and the limiting nut 14 is screwed onto the other end of the connecting cylinder 12; the outer surfaces of the connecting cylinder 12, the limiting sleeve 13, and the limiting nut 14 form an inwardly recessed annular rotating groove (the outer diameter of the limiting sleeve 13 and the limiting nut 14 is larger than the diameter of the rotating groove); the end of the supporting connecting bent rod 10 is fitted into the rotating groove. It can rotate along the annular groove, and its two sides are tightly attached to the limiting sleeve 13 and the limiting nut 14 respectively; the rotating annular groove provides a rotation track for the supporting connecting bent rod 10, ensuring smooth rotation; the limiting sleeve 13 and the limiting nut 14 form an axial limit by being tightly attached to the two sides of the supporting connecting bent rod 10 - which not only prevents the bent rod from axially moving when rotating, but also allows the bent rod to be fixed at any angle through friction (it will not rotate on its own due to vibration after adjustment), improving the stability of angle adjustment; at the same time, the combination structure of the three is easy to assemble.

[0038] Combination Figure 3As shown, the connecting cylinder 12 has a wiring connecting cavity 15 and a connecting opening 16 inside. One end of the connecting opening 16 is connected to the first wiring cavity 9, and the other end is connected to the second hollow wiring structure 6.

[0039] In this embodiment, the wiring connection cavity 15 is a hollow cavity inside the connecting cylinder 12, which is connected to the first wiring cavity 9 of the hollow screw 8 (the cable can enter the wiring connection cavity 15 from the first wiring cavity 9); the connection opening 16 is a through hole opened on the side wall of the connecting cylinder 12, one end of which is connected to the wiring connection cavity 15, and the other end is connected to the second hollow wiring structure 6 inside the supporting connecting bent rod 10.

[0040] The second hollow wiring structure 6 includes a second wiring chamber 17 disposed within the support connecting rod 10, and a side cover strip 18 is provided on the side of the support connecting rod 10 to engage with the support connecting rod 10.

[0041] In this embodiment, the supporting connecting rod 10 is a hollow rod, and the internal cavity is the second wiring chamber 17 (the cable enters here from the connecting opening 16); the side of the supporting connecting rod 10 has a strip-shaped opening along the length direction, the edge of the side cover strip 18 has a buckle, and the edge of the opening of the supporting connecting rod 10 has a slot. The buckle and the slot engage to cover the opening and seal the second wiring chamber 17.

[0042] Combination Figure 1-6 As shown, the ball joint connection assembly 4 includes a ball joint connecting rod 19 and a connecting ball joint 20 disposed at the head of the supporting connecting rod 10. The tail of the ball joint connecting rod 19 is inserted into the supporting connecting rod 10, and the connecting ball joint 20 is twistedly connected to the rearview mirror body 1.

[0043] In this embodiment, the ball joint connecting rod 19 is a hollow rod, with its tail inserted into the end of the supporting connecting bent rod 10 (fixed by interference fit or screw connection), and its head integrally formed with the connecting ball joint 20 (the connecting ball joint 20 is a spherical structure); the connecting ball joint 20 is embedded in the spherical groove on the back of the rearview mirror body 1, and can be flexibly twisted relative to the rearview mirror body 1.

[0044] Combination Figure 1-6 As shown, the third hollow wiring structure 7 includes a third wiring chamber 21 disposed in the ball head connecting rod 19 and a ball head opening 22 disposed in the ball head 20. The third wiring chamber 21 is connected to the second wiring chamber 17.

[0045] In this embodiment, the third wiring chamber 21 is a hollow channel inside the ball joint connecting rod 19. One end is connected to the second wiring chamber 17 supporting the connecting bent rod 10 (the cable enters the third wiring chamber 21 from the second wiring chamber 17), and the other end is connected to the ball joint opening 22 on the connecting ball joint 20. The ball joint opening 22 is a through hole opened on the surface of the connecting ball joint 20 and is connected to the mirror wiring space 24 inside the rearview mirror body 1.

[0046] Combination Figure 1-6 As shown, the rearview mirror body 1 is equipped with a ball head fixing back plate 23 on its back. The ball head fixing back plate 23 is fixed to the rearview mirror body 1 by bolts or screws. The rearview mirror body 1 is provided with a mirror wiring space 24. The ball head opening 22 is connected to the mirror wiring space 24.

[0047] In this embodiment, the ball head fixing back plate 23 is made of metal or rigid plastic plate and is fixed to the back of the rearview mirror body 1 by bolts or screws. Its inner side is provided with an arc-shaped groove that is adapted to the connecting ball head 20. When the ball head fixing back plate 23 is locked, the connecting ball head 20 is pressed between the spherical groove of the rearview mirror body 1 and the arc-shaped groove of the ball head fixing back plate 23 (leaving a slight gap to allow twisting). The cavity inside the rearview mirror body 1 is the mirror wiring space 24, which is connected to the ball head opening 22 (the cable enters the mirror wiring space 24 from the ball head opening 22 and connects to the sensor light).

[0048] The working principle of this utility model is as follows:

[0049] The vehicle cable passes through the hollow screw 8 at the end of the rearview mirror handle 2, and sequentially passes through the first wiring chamber 9, wiring connection chamber 15, connection opening 16, second wiring chamber 17, third wiring chamber 21, and ball head opening 22, finally entering the mirror body wiring space 24 of the rearview mirror body 1, where it connects to the sensor light (such as LED beads or sensor modules), completing the concealed wiring. When the lateral angle needs to be adjusted, the support connecting rod 10 is rotated—the support connecting rod 10 rotates along the rotating annular groove of the rotating connecting handle 11, and the limiting sleeves 13 and limiting nuts 14 on both sides maintain the adjustment through friction. After the holiday, when the tilt angle needs to be adjusted, the rearview mirror body 1 is twisted—the connecting ball joint 20 rotates between the spherical groove of the rearview mirror body 1 and the ball joint fixing back plate 23, and the angle is kept stable by the clamping force of the ball joint fixing back plate 23; during the adjustment process, the internal cable bends naturally with the rotation of the component and will not be pulled or squeezed; when the vehicle is started or the sensing conditions are triggered (such as turn signal, obstacle sensing), the vehicle power supply supplies power to the sensor light in the mirror wiring space 24 through the internal cable, and the sensor light illuminates (such as flashing synchronously when turning, and always on at night) to realize the safety warning function.

[0050] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.
