Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a height-adjustable adapter for a rearview mirror of an electric vehicle. Background Art

[0002] With the acceleration of urbanization, electric vehicles have gained widespread adoption worldwide as an environmentally friendly and convenient means of transportation. To improve riding safety, electric vehicles are often equipped with rearview mirrors, allowing the driver to observe traffic conditions behind them. However, in actual use, due to vehicle design and ergonomic considerations, the rearview mirrors of some electric vehicles are mounted low, making it difficult for the driver to obtain a good view. To address this issue, heightened adapters for electric vehicle rearview mirrors have become available on the market, increasing the height of the rearview mirror to improve the driver's field of view. However, the height of the heightened adapters currently available on the market is fixed and cannot be adjusted, requiring only replacement of different models.

[0003] Therefore, it is necessary to improve the above shortcomings of the prior art. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a height-adjustable adapter for an electric vehicle rearview mirror in view of the above-mentioned deficiencies in the prior art, so as to solve the problem that the height of the height-increasing adapter in the prior art cannot be adjusted.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a height-adjustable adapter for an electric vehicle rearview mirror, comprising a main body, the main body being divided into a first split and a second split, the first split being provided with a screw at one end and a receiving groove at the other end that can be axially slidably connected to the second split, the second split being provided with an internal threaded hole at the end away from the screw, and a limit adjustment mechanism being provided between the bottom end of the internal threaded hole and the receiving groove that can limit the axial relative position of the first split and the second split.

[0006] By adopting the above technical solution, the main body of the adapter is divided into a first split and a second split, and the second split can slide relatively in the accommodating groove of the first split. Therefore, the first split and the second split can be adjusted to a suitable relative position, and then the first split and the second split can be locked by triggering the limit adjustment mechanism, so that the two no longer slide relative to each other to complete the height adjustment of one side; when the height needs to be adjusted again, the limit adjustment mechanism is first released so that the first split and the second split can slide relatively to each other again to adjust the height, and then the limit adjustment mechanism is re-triggered to lock the first split and the second split; thereby, the adapter can be adjusted to a suitable height according to actual needs, with high flexibility, and no need to purchase multiple models of adapters.

[0007] The above technical solution is further configured as follows: the limit adjustment mechanism includes several movable slide grooves arranged on the second split body and connected to the bottom end of the internal threaded hole, a movable push plate slidably connected to the movable slide groove, and a limit plate connected to one end of the side wall of the movable slide close to the accommodating groove; the movable push plate is provided with an extrusion slope on the side of the hole opening facing the internal threaded hole close to the end of the internal threaded hole, and a pin shaft is provided at the other end; the pin shaft outer sleeve is provided with a return spring with one end abutting the movable push plate and the other end abutting the limit plate; the limit plate is provided with a through hole that is gap-matched with the pin shaft, and the side wall of the accommodating groove is provided with a plurality of pin holes that can cooperate with the pin shaft in an axial array.

[0008] The movable push plate drives the pin shaft to be reinserted into the pin hole to limit and lock the first and second parts again, thereby realizing multi-level height adjustment to adapt to more usage scenarios.

[0009] The above technical solution is further configured as follows: the second split body is provided with a limiting inclined block capable of abutting against the extrusion inclined surface at one end of the movable sliding groove close to the internal threaded hole.

[0010] By adopting the above technical solution, the movable push plate is limited by the limiting bevel block to prevent the movable push plate from excessively extending into the internal threaded hole, causing the screw end of the rearview mirror to be stuck and unable to abut against the extrusion bevel.

[0011] The above technical solution is further configured as follows: a transition arc surface is provided between the end surface of the movable push plate close to the internal threaded hole and the extrusion inclined surface.

[0012] By adopting the above technical solution, by providing a transition arc surface, the movable push plate can be more smoothly pressed by the screw end on the rearview mirror, thereby reducing wear.

[0013] The above technical solution is further configured as follows: the end of the pin shaft close to the pin hole is configured as a round head, and the open end of the pin hole close to the pin shaft has a rounded corner.

[0014] By adopting the above technical solution, the pin can be inserted into the pin hole more easily through the cooperation between the round head of the pin and the rounded corner of the pin hole opening.

[0015] The above technical solution is further configured as follows: a stepped groove is provided at one end of the movable slide close to the pin hole, and the limit plate is interference-fitted in the stepped groove.

[0016] By adopting the above technical solution, the limit plate is interference-mounted in the stepped groove, which does not interfere with the relative sliding of the first split body and the second split body and is easy to install.

[0017] The above technical solution is further configured as follows: the peripheral side surfaces of the first split body and the second split body are configured as hexagonal surfaces and a position limiting adjustment mechanism is correspondingly provided on each surface.

[0018] By adopting the above technical solution, the hexagonal surfaces on the peripheral sides of the first and second split bodies can facilitate the use of wrenches and other tools to disassemble and assemble the height-increasing adapter. A limit adjustment mechanism is set on each surface, which is not only beautiful but also makes the ball force balanced and more stable.

[0019] The beneficial effects achieved by the utility model are: the adapter can be adjusted to a suitable height according to actual needs, the flexibility is high, and there is no need to purchase multiple models of adapters. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1-4 As shown in, a height-adjustable adapter for an electric vehicle rearview mirror comprises a main body 1, which is divided into a first sub-body 2 and a second sub-body 3. One end of the first sub-body 2 is provided with a screw 4, and the other end is provided with an accommodating groove 20 which can be axially slidably connected to the second sub-body 3. The second sub-body 3 is provided with an internal threaded hole 30 at one end away from the screw 4. A limit adjustment mechanism is provided between the bottom end of the internal threaded hole 30 and the accommodating groove 20, which can limit the axial relative position of the first sub-body 2 and the second sub-body 3. The limit adjustment mechanism comprises a plurality of movable slide grooves 31 arranged on the second sub-body 3 and connected to the bottom end of the internal threaded hole 30, a movable push plate 5 slidably connected to the movable slide groove 31, and a limit plate 6 connected to one end of the side wall of the movable slide groove 31 near the accommodating groove 20. The movable push plate 5 is provided with an extrusion inclined surface 51 on the side of the opening of the internal threaded hole 30 near one end of the internal threaded hole 30, and a pin shaft 52 at the other end. The outer sleeve of the pin shaft 52 is provided with a return spring 7 at one end which abuts the movable push plate 5 and the other end abuts the limit plate 6. The limit plate 6 is provided with a through hole 60 that fits the gap with the pin shaft 52. The side wall of the accommodating groove 20 is axially arrayed with several pin holes 21 that can cooperate with the pin shaft 52. The second split body 3 is located at the end of the movable slide groove 31 near the internal threaded hole 30 and is provided with a limiting oblique block 32 that can abut against the extrusion inclined surface 51. A transition arc surface 53 is provided between the end face of the movable push plate 5 near the internal threaded hole 30 and the extrusion inclined surface 51. The end of the pin shaft 52 near the pin hole 21 is set as a round head, and the open end of the pin hole 21 near the pin shaft 52 is rounded. The movable slide groove 31 is provided with a stepped groove 33 at one end near the pin hole 21, and the limit plate 6 is interference mounted in the stepped groove 33; the peripheral side surfaces of the first split body 2 and the second split body 3 are set as hexagonal surfaces and each surface is correspondingly provided with a limit adjustment mechanism.

[0027] In the above embodiment, the body 1 of the adapter is divided into a first sub-body 2 and a second sub-body 3, and the second sub-body 3 can slide relatively in the accommodating groove 20 of the first sub-body 2. When the height of the adapter needs to be adjusted, the rearview mirror can be rotated first to drive the screw end to rotate and gradually rotate out of the internal threaded hole 30 until the screw end no longer abuts against the movable push plate 5. Then, the movable push plate 5 slides toward the center along the movable slide groove 31 under the elastic force of the return spring 7, driving the pin shaft 52 to disengage from the pin hole 21, thereby releasing the first sub-body 2 and the second sub-body 3. The movable push plate 5 drives the pin shaft 52 to be reinserted into the pin hole 21 to limit and lock the first and second split bodies 2, 3 again, thereby realizing multi-gear height adjustment with high flexibility, adapting to more usage scenarios, and eliminating the need to purchase multiple models of adapters.
