Description

Technical Field

[0001] This technical solution relates to the field of rearview mirror technology, specifically to an anti-theft mirror rod for a rearview mirror. Background Technology

[0002] The mirror rod is a rod-shaped component mounted on the front of the vehicle to support and connect the rearview mirror.

[0003] For example, a novel rearview mirror disclosed in Chinese patent CN201820654069.X is fixed by threading the end of the mirror rod with the threaded hole at the front of the vehicle. However, this mirror rod connection structure still has some shortcomings: due to errors or unreasonable thread design, when the mirror rod is tightened, the thread fit will affect the angle or orientation of the mirror rod after it is installed on the front of the car, causing the mirror rod to deviate from the preset angle. This will cause the rearview mirror at the top of the mirror rod to shift in the spatial position of the rearview mirror at the front of the car, making it impossible to effectively observe the road conditions behind. If the connection between the mirror rod and the front of the car is loosened to adjust the position or angle of the mirror rod, the mirror rod will become loose. Vibrations or collisions during vehicle movement can easily change the angle of the mirror rod, affecting the observation effect of the rearview mirror and making it difficult to monitor the rear traffic conditions in real time. At the same time, since the mirror rod is connected to the front of the car through the end thread, under the lever principle, thieves only need to drive the upper end of the mirror rod or drive the rearview mirror to make the mirror rod rotate around the connection and remove it from the front of the car, resulting in the theft of the rearview mirror, which is not very safe or theft-proof. Utility Model Content

[0004] The purpose of this technical solution is to provide an anti-theft mirror rod for a rearview mirror. By using a locking sleeve and an elastic element, the mirror rod can be stably limited and easily adjusted, thus improving the problems of inaccurate mirror rod angle, easy loosening, and inconvenient angle adjustment.

[0005] The purpose of this technical solution is achieved as follows: A rearview mirror anti-theft rod, comprising: The connecting seat has an installation groove at its upper end and a screw for connecting with the front of the vehicle at its lower end. An elastic element is installed within the mounting groove; The lower end of the mirror rod is movably placed in the mounting groove and movably abuts against the elastic element; A locking sleeve is installed on the mirror rod and threadedly connected to the upper end of the connecting seat; By adjusting the position of the locking sleeve on the connecting seat, the locking sleeve drives the lower end of the lens rod to press against the elastic element. Under the elastic force of the elastic element, the rotation of the lens rod on the connecting seat is restricted.

[0006] Preferably, the locking sleeve has a through hole, the upper inner wall of the through hole is provided with a protrusion, and the lower side wall of the lens rod is provided with an anti-detachment component; When the lower end of the lens rod is inserted into the through hole, the anti-detachment component is placed inside the through hole, and the protrusion abuts against the anti-detachment component to prevent the lens rod from detaching from the connecting seat.

[0007] Preferably, the lower end sidewall of the lens rod is provided with a snap-fit ​​groove, the anti-detachment component is snapped into the snap-fit ​​groove, and the side end of the anti-detachment component protrudes from the lower end sidewall of the lens rod.

[0008] Preferably, the anti-detachment component is an open retaining ring.

[0009] Preferably, the lower end sidewall of the lens rod is provided with a snap-fit ​​hole, and a pin is provided in the snap-fit ​​hole, the end of the pin protruding from the lower end sidewall of the lens rod.

[0010] Preferably, the lower inner wall of the through hole is provided with a threaded portion one, and the upper outer wall of the connecting seat is provided with a threaded portion two. The locking sleeve is fitted onto the upper end of the connecting seat through the through hole, and the threaded portion one and the threaded portion two are threadedly connected to realize the connection between the locking sleeve and the connecting seat.

[0011] Preferably, the elastic element is a rubber block, a silicone block, or a spring.

[0012] Preferably, the connecting seat has a driving part in the middle, and the connecting seat is driven to rotate by the driving part.

[0013] Preferably, the outer side of the locking sleeve has a second driving part, which drives the locking sleeve to rotate.

[0014] The key and beneficial technical effects of this technical solution compared to existing technologies are: This technical solution uses a locking sleeve to drive the lower end of the mirror rod to press against an elastic element. The elastic force of the elastic element restricts the rotation of the mirror rod on the connecting seat, ensuring the stability and firmness of the mirror rod installation on the connecting seat. When it is necessary to adjust the angle of the mirror rod, there is no need to rotate the locking sleeve; only external force is needed to overcome the force of the elastic element to drive the mirror rod to rotate, thereby adjusting the installation angle of the mirror rod and ensuring that the rearview mirror can effectively observe road conditions. The operation is simple and convenient, improving the user experience. At the same time, the locking sleeve of this design requires an additional tool to drive it to rotate on the connecting seat, thus enabling the mirror rod to be disassembled. Thieves cannot turn the locking sleeve by hand, increasing the difficulty of disassembly and the anti-theft capability, avoiding the problem of easy theft of rearview mirrors.

[0020] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0021] Example 1: Combination Figures 1-4 A rearview mirror anti-theft rod, comprising: The connecting seat 1 has an installation groove 11 at its upper end and a screw 12 at its lower end for connecting with the front of the vehicle. The screw 12 is threadedly connected to the threaded hole of the front of the electric vehicle to realize the installation of the connecting seat 1. The elastic element 2 is installed in the mounting groove 11, that is, the elastic element 2 is placed in the mounting groove 11; The lower end (i.e., the lower half) of the mirror rod 3 is movably placed in the mounting groove 11, and the lower end face of the mirror rod 3 movably abuts against the upper end face of the elastic member 2. The upper end of the mirror rod 3 is used to connect the rearview mirror. Locking sleeve 4 is installed on the lens rod 3 and threadedly connected to the upper end of the connecting seat 1. That is, locking sleeve 4 is sleeved on the outer side of the lower half of the lens rod 3, and locking sleeve 4 and the upper end of connecting seat 1 are threadedly connected. By adjusting the position of the locking sleeve 4 on the connecting seat 1, the locking sleeve 4 drives the lower end of the mirror rod 3 to press against the elastic element 2 and deform the elastic element 2. Under the elastic force of the elastic element 2, the friction between the elastic element 2 and the lower end of the mirror rod 3 increases, and the friction between the elastic element 2 and the mounting groove 11 increases, thereby restricting the rotation of the mirror rod 3 on the connecting seat 1. This ensures that the angle of the mirror rod 3 on the connecting seat 1 will not change due to vehicle vibration, and that the mirror rod 3 can be maintained at the set position or angle.

[0022] When it is necessary to adjust the position of the lens rod 3 on the connecting seat 1, it is only necessary to overcome the force of the elastic element 2 by external force, thereby overcoming the friction between the locking sleeve 4 and the lens rod 3, as well as the friction between the elastic element 2 and the lower end of the lens rod 3, so that the lens rod 3 can rotate on the connecting seat 1. There is no need to loosen the locking sleeve 4, making the adjustment simple and quick.

[0023] When it is necessary to twist and rotate the locking sleeve 4 on the connecting seat 1, due to the small structure of the locking sleeve 4, that is, when the locking sleeve 4 is driven to rotate by hand, the lever arm is small and a large force is required, which makes it difficult to rotate the locking sleeve 4. Tools such as wrenches are needed to drive the locking sleeve 4 to rotate on the connecting seat 1, which increases the difficulty of theft and improves the anti-theft performance. Similarly, driving the connecting seat 1 to rotate on the front of the vehicle also requires additional tools, which increases the firmness of the connecting seat 1 installed on the front of the vehicle.

[0024] Combination Figures 3-4 The locking sleeve 4 has a through hole 41, which passes through the upper and lower end faces of the locking sleeve 4. A protrusion 42 is provided on the upper inner wall of the through hole 41, and an anti-detachment part 5 is provided on the lower side wall of the lens rod 3. When the lower end of the lens rod 3 is inserted into the through hole 41, the anti-detachment component 5 is placed inside the through hole 41 from the lower end of the through hole 41, and the lower end of the protrusion 42 abuts against the upper end of the anti-detachment component 5 to prevent the lens rod 3 from detaching from the connecting seat 1. By the protrusion 42 abutting against the anti-detachment component 5, the locking sleeve 4 drives the lower end of the lens rod 3 to move toward the bottom of the mounting groove 11, so that the lens rod 3 squeezes the elastic component 2 and prevents the lens rod 3 from detaching from the connecting seat 1.

[0025] Combination Figures 3-4 The lower end (i.e., the lower half) of the lens rod 3 is provided with a snap-fit ​​groove 31 around its side wall. The anti-detachment component 5 is snapped into the snap-fit ​​groove 31, and the side end of the anti-detachment component 5 protrudes from the side wall of the lower end of the lens rod 3. The outer diameter of the anti-detachment component 5 is larger than the inner diameter of the through hole 41 at the location of the protrusion 42, so as to ensure the stability of the protrusion 42 abutting against the anti-detachment component 5.

[0026] like Figure 3 The snap-fit ​​groove 31 has a movable space 32, meaning that the distance between the two opposite side walls of the snap-fit ​​groove 31 is greater than the thickness of the anti-detachment component 5. The movable space 32 allows the anti-detachment component 5 to move along the axial direction of the lower end of the lens rod 3 within the snap-fit ​​groove 31. That is, after the protrusion 42 presses the anti-detachment component 5 against the upper end of the connecting seat 1, the movable space 32 allows the lower end of the lens rod 3 to move axially within the mounting groove 11 under external force. When the lens rod 3 is rotated and its angle is adjusted, the lens rod 3 can be pressed down, causing the anti-detachment component 5 to separate from the two opposite side walls of the snap-fit ​​groove 31, reducing the friction and wear of rotation.

[0027] The anti-slip component 5 is an open retaining ring or retaining ring.

[0028] Combination Figures 3-4 The lower inner wall of the through hole 41 is provided with a threaded part 43, and the upper outer wall of the connecting seat 1 is provided with a threaded part 13. The locking sleeve 4 is fitted onto the upper end of the connecting seat 1 through the through hole 41. The threaded part 43 and the threaded part 13 are threadedly connected to realize the connection between the locking sleeve 4 and the connecting seat 1.

[0029] By adjusting the connection position between the locking sleeve 4 and the connecting seat 1, the distance between the protrusion 42 and the connecting seat 1 can be adjusted, thereby adjusting the squeezing force of the lens rod 3 on the elastic element 2, and correspondingly adjusting the external force required to drive the lens rod 3 to rotate on the connecting seat 1.

[0030] The protrusion 42 abuts against the anti-slip member 5, causing the anti-slip member 5 to drive the lower end of the lens rod 3 to abut against the upper end of the elastic member 2.

[0031] The friction between the lens rod 3 and the elastic element 2, the friction between the elastic element 2 and the inner side of the mounting groove 11, the friction between the lens rod 3 and the anti-detachment element 5, and the friction between the anti-detachment element 5 and the locking sleeve 4 are used to ensure that the lens rod 3 is maintained at a set angle on the connecting seat 1, that is, to prevent the lens rod 3 from rotating on the connecting seat 1.

[0032] The elastic element 2 is a rubber block, silicone block, or spring. When the elastic element 2 is a spring, it can be a helical spring or a disc spring.

[0033] Combination Figure 1 and Figure 4 The connecting seat 1 has a drive part 14 in the middle. The drive part 14 is similar in shape to a hexagonal nut, that is, the cross section of the drive part 14 perpendicular to its axis is hexagonal. The connecting seat 1 is driven to rotate on the front of the vehicle by using tools such as a wrench in conjunction with the drive part 14.

[0034] Combination Figure 1 and Figure 4 The outer side of the locking sleeve 4 has a driving part 2 44, which is similar in shape to a hexagonal nut. That is, the cross section of the driving part 2 44 perpendicular to its axis is hexagonal. The locking sleeve 4 is driven to rotate on the connecting seat 1 by using tools such as a wrench in conjunction with the driving part 2 44.

[0035] Example 2: The design scheme of this embodiment is basically the same as that of Embodiment 1, except that: The lower half of the lens rod 3 has a snap-fit ​​hole on its side wall. The axis of the snap-fit ​​hole is not parallel to the axis of the lower half of the lens rod 3. The snap-fit ​​hole is threaded or interference-fitted with a pin. The end of the pin protrudes from the side wall of the lower end of the lens rod 3, that is, the end of the pin extends out of the snap-fit ​​hole. The part of the pin placed outside the snap-fit ​​hole abuts against the lower end of the protrusion 42.
