A rear view mirror 100 of a vehicle and a vehicle according to an embodiment of the present invention are described below with reference to the accompanying drawings.

Referring to fig. 1 to 3, a rear view mirror 100 for a vehicle according to an embodiment of the present invention may include: the endoscope comprises an endoscope body 10, a base 20, a ball head kit, an elastic piece 50 and a sleeve 60, wherein the ball head comprises a first ball head 31 and a second ball head 32, and the ball head kit comprises a first ball head kit 41 and a second ball head kit 42.

Specifically, the first ball head 31 is connected to the mirror body 10, and the first ball head 31 is fitted into the first ball head kit 41, the second ball head 32 is connected to the base 20, and the second ball head 32 is fitted into the second ball head kit 42. The elastic member 50 is disposed between the first ball socket 41 and the second ball socket 42, and the first ball socket 41, the second ball socket 42 and the elastic member 50 are located in the sleeve 60.

Therefore, the sleeve 60 can limit and shield the first ball head 31, the first ball head kit 41, the second ball head 32, the second ball head kit 42 and the elastic piece 50, so that the elastic piece 50 can press the first ball head kit 41 and the second ball head kit 42 on two sides, and further the first ball head kit 41 and the second ball head kit 42 can provide damping for the first ball head 31 and the second ball head 32, so that the rearview mirror 100 can be kept at a certain spatial position after being adjusted by a driver according to conditions, a rearview function is provided for the driver, and the rearview mirror can be kept at the spatial position without automatic sagging under bumping and shaking during driving.

In some embodiments, as shown in fig. 1 and 3, the ball joint sleeve may be a damping claw, an end of the damping claw is formed into a necking structure, and under the elastic force of the elastic member 50, the contact pressure between the damping claw and the ball joint can be ensured, a sufficiently large contact area is ensured, the ball joint is uniformly stressed, and the hidden danger of the rearview mirror 100 that the rearview mirror sags and fails is reduced.

However, the driver needs to adjust the rearview mirror frequently according to the situation, and the damping claw and the ball head are abraded along with the use time due to the bumping and shaking in the long-term driving. In the related technology, the sleeve of the rearview mirror is a disposable assembly part, a new spring cannot be disassembled and replaced repeatedly, when the spring fails due to fatigue or the damping claw and the ball head are abraded, the spring cannot compensate pressure drop caused by abrasion, contact pressure between the damping claw and the ball head is reduced, the maximum contact area cannot be guaranteed, the ball head is uneven in stress, finally the rearview mirror is prone to droop more and more in use until the rearview mirror fails, hidden dangers are great, and driving safety is seriously affected. And after the rearview mirror is caused to droop and lose efficacy, only the whole rearview mirror with a high price can be replaced.

Therefore, in the present invention, as shown in fig. 1 and 5, the sleeve 60 includes a first cylinder 61 and a second cylinder 62, and the first cylinder 61 and the second cylinder 62 are detachably coupled. Therefore, as the service time goes on, when the elastic member 50 fails to work due to fatigue or the ball head set and the ball head are worn, and the old elastic member 50 cannot compensate the pressure drop caused by wear, the first cylinder 61 and the second cylinder 62 can be detached to replace the new elastic member 50 or replace the severely worn ball head set and the ball head. After the rearview mirror 100 is out of work, only part of parts need to be replaced, the whole rearview mirror 100 with a high price does not need to be replaced, the cost for replacing the rearview mirror 100 for a plurality of times is saved for a vehicle owner, and the maintenance cost is reduced.

Because cost of maintenance reduces, when rear-view mirror 100 appears drooping easily, fixed unstable phenomenon, the car owner is difficult for not maintaining the change in time because of the price is expensive, consequently, be favorable to making more rear-view mirrors 100 of in-use vehicle keep better operating condition, the pressure drop that the elastic component 50 can effectively compensate the wearing and tearing and lead to guarantees the contact pressure between first bulb external member 41 and first bulb 31 and the contact pressure between second bulb external member 42 and second bulb 32, rear-view mirror 100 is difficult for drooping in use, the emergence of incident has effectively been reduced. The detachable sleeve 60 has a simple structure, is easy to manufacture, has low cost, and has great economic and social benefits for the related industries of the vehicle rearview mirror 100.

According to the rearview mirror 100 of the vehicle, the sleeve 60 is arranged into the first barrel 61 and the second barrel 62 which are detachably connected, so that the elastic part 50, the first ball head sleeve 41, the second ball head sleeve 42, the first ball head 31 and the second ball head 32 of the rearview mirror 100 can be replaced, the problem that the rearview mirror needs to be integrally replaced after the rearview mirror is subjected to droop failure in the related art is solved, the cost for replacing the rearview mirror 100 for a plurality of times is saved for a vehicle owner, and the driving safety is guaranteed.

According to some embodiments of the present invention, the first cylinder 61 and the second cylinder 62 can be connected by plugging, and the plugging size can be adjusted. From this, when bulb external member and bulb wearing and tearing or elastic component 50 lead to contact pressure to reduce, can be through the grafting size of increase first barrel 61 and second barrel 62, adjust the compression capacity of elastic component 50, adjust the degree of compression of elastic component 50 promptly, and then can adjust the contact pressure between first bulb 31 and first bulb external member 41, between second bulb 32 and the second bulb external member 42, adjust the damped size that first bulb 31 and second bulb 32 received, can effectively reduce the replacement frequency of parts such as elastic component 50, the bulb external member, and improve life, further save cost for the car owner. In addition, in case that the rear view mirror 100 droops during long-distance running, the vehicle owner cannot replace the rear view mirror 100 or replace the elastic member 50 and other parts in time, and can adjust the plugging size of the first cylinder 61 and the second cylinder 62 by himself to solve the drooping problem of the rear view mirror 100, thereby avoiding traffic accidents.

In addition, in the related technology, the structure of the two ends of the disposable metal sleeve is assembled by a necking process with the assistance of special equipment after the damping claws, the ball heads, the springs and the like are arranged in the metal sleeve during manufacturing, and the technology is difficult to master. The damping effect has a great relationship with the metal material, the parameters of the necking and the like. The degree of necking affects the friction force between the ball head and the damping claw, and if the necking force is too large, the rearview mirror cannot be adjusted easily, reworking cannot be performed, waste products occur, and the yield is not high; if the necking force is too small, the rearview mirror is easy to turn around, although the rearview mirror can be reworked and subjected to necking again, the product performance produced by the manufacturing process is not high in consistency.

In the embodiment of the present invention, since the first cylinder 61 and the second cylinder 62 are detachable, the necking structure of the first cylinder 61, the necking structure of the second cylinder 62, the necking structure of the first ball head set 41, and the necking structure of the second ball head set 42 can be respectively processed by a necking process, which can significantly reduce the processing technical difficulty and the assembly difficulty, the necking force control is easier, the rejection rate is lower, and the reduction of the production cost is facilitated. Because first barrel 61 and second barrel 62 are adjustable, consequently, even there is the error in the throat of sleeve 60, first bulb external member 41 and second bulb external member 42, also can be through adjusting the grafting size of first barrel 61 and second barrel 62 to compensate the error through the compressive capacity that changes elastic component 50, stopped the throat failure and can not do over again the defective products that cause, manufacturing efficiency is very improved, manufacturing cost greatly reduced.

For example, in some embodiments, as shown in fig. 1 and 5, the first cylinder 61 is sleeved outside the second cylinder 62, and the axial dimension of the second cylinder 62 extending into the first cylinder 61 is adjustable. In other embodiments, the second cylinder 62 is sleeved on the first cylinder 61, and the axial dimension of the first cylinder 61 extending into the second cylinder 62 is adjustable.

The following description will be given to an insertion structure of the first cylinder 61 and the second cylinder 62 by taking the first cylinder 61 sleeved on the second cylinder 62 as an example, and the technical scheme of sleeving the second cylinder 62 on the first cylinder 61 will be understood by those skilled in the art according to the following description.

The connection mode of the first cylinder 61 and the second cylinder 62 is not particularly limited in the present invention, and in some embodiments, as shown in fig. 5, 7 and 8, the first cylinder 61 and the second cylinder 62 are connected by a screw thread, so that the connection mode is simple and the assembly is easier, and the screw thread structure makes the insertion size adjustment of the first cylinder 61 and the second cylinder 62 easier and the adjustment precision is higher.

In some embodiments of the present invention, as shown in fig. 5, 7 and 8, the first cylinder 61 includes a straight cylinder section 611 and a variable diameter cylinder section 612, an inner circumferential surface of the straight cylinder section 611 is provided with an internal thread, and an outer circumferential surface of the second cylinder 62 is provided with an external thread, so that the straight cylinder section 611 and the second cylinder 62 can be connected by a thread. The inner diameter of the reducing cylinder section 612 decreases in the direction away from the straight cylinder section 611 along the axial direction of the sleeve 60, so that a necking is formed at the end of the first cylinder 61, on one hand, the reducing cylinder section 612 can limit the first ball head sleeve 41, on the other hand, the reducing cylinder section 612 can limit the size of the second cylinder 62 inserted into the first cylinder 61, and when the second cylinder 62 abuts against the reducing cylinder section 612, a vehicle owner can be prompted to replace the elastic part 50 and other parts.

For example, two second barrels 62 are shown in fig. 5, wherein the second barrel 62 spaced apart from the variable diameter barrel section 612 (the second barrel 62 on the left side in fig. 5) represents an initial position where the first barrel 61 and the second barrel 62 of a new rear view mirror 100 or a repair-completed rear view mirror 100 are inserted; the second cylinder 62 (the second cylinder 62 on the right side in fig. 5) contacting the variable diameter cylinder section 612 indicates a state in which the rear view mirror 100 cannot solve the sagging problem of the rear view mirror 100 by adjusting the insertion size of the first cylinder 61 and the second cylinder 62, that is, a state in which the elastic member 50 and other parts need to be replaced. The distance between the two positions of the second cylinder 62 is the maximum adjustable dimension S of the plugging dimension of the second cylinder 62 and the first cylinder 61, for example, the maximum adjustable dimension of the axial dimension of the second cylinder 62 extending into the first cylinder 61.

According to some embodiments of the present invention, as shown in fig. 5, the end of the reducing cylinder section 612 close to the straight cylinder section 611 is provided with an annular avoiding groove 613, and the maximum radial dimension of the annular avoiding groove 613 is larger than the inner diameter of the straight cylinder section 611. The annular avoiding groove 613 can avoid the end of the second cylinder 62, which is beneficial to increasing the maximum adjustable dimension S of the first cylinder 61 and the second cylinder 62, and further improving the service life of the elastic part 50 and other parts.

In some embodiments, as shown in fig. 5, the end of the second cylinder 62 may be formed with a chamfer, and the chamfer structure may also increase the maximum adjustable dimension S of the first cylinder 61 and the second cylinder 62, thereby improving the service life of the elastic member 50 and other components.

According to some embodiments of the present invention, referring to fig. 6-8, the first cylinder 61 is sleeved on the second cylinder 62, the first cylinder 61 has a first limiting channel 614, the second cylinder 62 has a second limiting channel 621, the fastening member 70 can extend into the first limiting channel 614 and the second limiting channel 621, and one of the first limiting channel 614 and the second limiting channel 621 extends along the axial direction of the sleeve 60.

Therefore, the first limiting channel 614 or the second limiting channel 621 extending along the axial direction of the sleeve 60 can adapt to the adjustment of the plugging size of the first barrel 61 and the second barrel 62, after the first barrel 61 and the second barrel 62 are adjusted in place, namely, the plugging size of the first barrel 61 and the second barrel 62 is adjusted to the extent that the first ball head 31 and the second ball head 32 are damped to enable the rearview mirror 100 not to easily sag, the fastener 70 is matched with the first limiting channel 614 and the second limiting channel 621 to limit the relative rotation of the first barrel 61 and the second barrel 62, and even if the threaded connection structure is not loosened, the reliability of connection of the first barrel 61 and the second barrel 62 is ensured.

In the embodiment of the present invention, the specific structures of the first limiting channel 614 and the second limiting channel 621 can be flexibly configured according to practical situations. For example, in the example shown in fig. 7 and 8, the first limiting channel 614 is a through hole provided in the first cylinder 61, so that the fastening element 70 can pass through the through hole and cooperate with the second limiting channel 621, and the through hole can limit the fastening element 70, so that the fastening element 70 is not easy to fall and lose. The second limiting channel 621 is a limiting groove, the notch of the limiting groove faces the first cylinder 61, namely faces away from the axis of the second cylinder 62, the limiting groove extends along the axial direction of the second cylinder 62, the fastener 70 extends into the limiting groove and then does not extend into the second cylinder 62, and the fastener does not interfere with the elastic part 50 and the like, and is favorable for improving the structural strength of the second cylinder 62.

In some embodiments, as shown in fig. 8, the second limiting channel 621 is a plurality of second limiting channels 621, and the plurality of second limiting channels 621 are distributed at intervals along the circumferential direction of the second cylinder 62. After the first cylinder 61 and the second cylinder 62 are in threaded connection and the inserting size is adjusted in place, the fastener 70 can be matched with any one of the second limiting channels 621, and the adjusting precision can be improved.

In some embodiments, as shown in fig. 8, the second limiting channel 621 is a limiting groove, and the plurality of limiting grooves are uniformly distributed at intervals along the circumferential direction of the second cylinder 62, so that when the first cylinder 61 rotates relative to the second cylinder 62, the minimum rotation angle at each time is consistent, the adjustment precision can be improved, and the operability is higher.

Specifically, for a single thread, the axial distance between corresponding points of two adjacent threads is equal to the thread pitch p, if the number of the second limiting channels 621 is N, the axial moving distance of the first cylinder 61 relative to the second cylinder 62 is one thread pitch p every time the first cylinder rotates one full turn, and the axial moving distance is p/N every time the first cylinder rotates one second limiting channel 621; rotating the N second limiting channels 621, that is, rotating the first cylinder 61 relative to the second cylinder 62 for one turn, wherein the axial moving distance is one pitch p; the first cylinder 61 rotates one turn relative to the second cylinder 62, which is equivalent to two total turns, and the axial moving distance is two screw pitches p.

For example, in one embodiment, the thread is a single thread, the thread pitch p is 1mm, the number of the second limiting channels 621 is 12, and the total compression amount of the adjusting elastic element 50 is 0.077mm per 30 ° of rotation of the first cylinder 61 relative to the second cylinder 62.

In some embodiments, the number N of second limiting channels 621 satisfies: n is more than or equal to 8 and less than or equal to 20. For example, in some embodiments, N may be 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and so forth. In the value range, the number of the second limiting channels 621 is enough to ensure the adjustment precision, and the influence on the structural strength of the second cylinder 62 due to the excessive number of the second limiting channels 621 is avoided.

According to some embodiments of the present invention, as shown in fig. 5 and 6, the second limiting channel 621 extends along the axial direction of the sleeve 60 for a length L, the maximum adjustable dimension of the axial dimension of the second cylinder 62 extending into the first cylinder 61 is S, and L ≧ S, so as to prevent the fastener 70 from interfering with the end of the second limiting channel 621 away from the scope 10 when the axial dimensions of the first cylinder 61 and the second cylinder 62 are adjusted, and ensure that the first cylinder 61 and the second cylinder 62 can be adjusted to the maximum adjustable dimension.

According to some embodiments of the present invention, as shown in fig. 1 and 11, the elastic member 50 includes a plurality of belleville springs 51, and the plurality of belleville springs 51 are stacked in the axial direction of the sleeve 60. Compared with a spiral spring, the belleville spring 51 is less prone to tilting and dislocation, so that the supporting stability of the elastic piece 50 on the first ball head kit 41 and the second ball head kit 42 is improved, and the first ball head kit 41 and the second ball head kit 42 are stressed more uniformly. In addition, after the rear-view mirror 100 is out of service due to abrasion of the ball head and the ball head kit, if the old belleville springs 51 are not damaged, the maintenance can be carried out by increasing the number of the belleville springs 51 without replacing the old belleville springs 51, and the maintenance cost is further reduced.

In some embodiments of the present invention, as shown in fig. 1 and 4, the rearview mirror 100 further includes a pressure sensor 80, the pressure sensor 80 is disposed between two of the belleville springs 51, and the pressure sensor 80 is used for detecting the elastic force of the elastic member 50, so that a driver can more directly and accurately know the degree of compression of the elastic member 50, know the contact pressure between the ball socket set and the ball, or adjust the insertion size of the first cylinder 61 and the second cylinder 62 according to the detection result of the pressure sensor 80, and further adjust the degree of compression of the elastic member 50, that is, adjust the amount of damping applied to the first ball 31 and the second ball 32.

In some embodiments, as shown in FIG. 1, the number of Belleville springs 51 on either side of the pressure sensor 80 is equal. That is, the number of the disc springs 51 acting on the first ball socket 41 is equal to the number of the disc springs 51 acting on the second ball socket 42, which is beneficial to improving the uniformity of the stress of the first ball socket 41 and the second ball socket 42.
