Description

Technical Field

[0001] This utility model relates to the field of spare tire installation technology, specifically to an auxiliary device for installing a spare tire in a new energy vehicle. Background Technology

[0002] As the global automotive industry transitions to electrification, new energy vehicles have become one of the ways people travel. However, during the use of new energy vehicles, tire blowouts can occur on the road. In such cases, it is necessary to replace the tire with a spare tire to ensure the normal operation of the new energy vehicle. In this process, a spare tire installation auxiliary device is needed to help users install the spare tire more easily and safely.

[0003] Currently, when installing a spare tire on a new energy vehicle, the vehicle is first lifted with a jack, the tire is removed, the spare tire is aligned with the installation position, and finally, the spare tire is fixed in place by tightening the bolts with an auxiliary tool. Traditional auxiliary tools consist of a rod and a knob that matches the bolt. When the knob cannot be turned by hand, the auxiliary tool needs to be turned by foot to tighten the bolt.

[0004] Regarding the aforementioned technologies, since the pole is cylindrical, when stepping on it, the foot may slide on the curved pole, resulting in reduced efficiency in installing the spare tire. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for installing a spare tire in a new energy vehicle. When it is impossible to turn the tire by hand, a pedal is installed on the rod, allowing the user to step on the pedal to assist in turning the tire, thereby reducing the possibility of shoes slipping.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] In a first aspect, this utility model provides an auxiliary device for installing a spare tire in a new energy vehicle, including a rotating rod and a rotating head installed at the end of the rotating rod. The rotating head has a slot for a bolt to be fitted into it, and also includes a pedal, which is detachably installed at the end of the rotating rod away from the rotating head.

[0008] By adopting the above technical solution, when installing the spare tire of a new energy vehicle, the bolt is first inserted into the slot of the rotating head. Then, the user first turns the rotating rod by hand until it can no longer be turned. Then, the pedal is removed and installed on the end of the rotating rod away from the rotating head. The user can then step on the pedal to continue tightening the bolt. During this process, since the user does not need to step on the curved surface of the rotating rod, the possibility of foot slippage is reduced, and the installation efficiency is improved.

[0009] Optionally, a base is fixedly installed at the bottom of the pedal, and the base has a insertion slot. The rotating rod is inserted into the base through the insertion slot. The base is equipped with a locking component for limiting the rotating rod within the insertion slot.

[0010] Optionally, the locking assembly includes a limiting block and a locking member. The limiting block has a polygonal cross-section and is fixedly installed at the end of the rotating rod away from the rotating head. The bottom of the insertion slot has a limiting groove adapted to the limiting block, and the limiting block is inserted into the base through the limiting groove. The locking member is used to limit the limiting block to be stable within the limiting groove.

[0011] Optionally, the locking component includes a locking block and a pull rod. The base has a sliding cavity communicating with the limiting groove. The locking block is slidably installed in the base through the sliding cavity. The limiting block has a locking hole. One end of the locking block extends into the limiting groove and passes through the locking hole. The pull rod is fixedly connected to the other end of the locking block. The end of the pull rod away from the locking block extends out of the base.

[0012] Optionally, a connecting block is connected between the locking block and the pull rod, and the connecting block is slidably installed on the base through the sliding cavity; the pull rod is sleeved with an elastic element, and the two ends of the elastic element are respectively fixedly connected to the groove wall of the connecting block and the sliding cavity. When the locking block passes through the locking hole, the elastic element is in a natural state.

[0013] Optionally, a pulling block is fixedly installed at one end of the pull rod that extends beyond the base, and the cross-sectional area of ​​the pulling block is larger than the cross-sectional area of ​​the pull rod.

[0014] Optionally, a receiving groove is provided on the side of the pedal away from the base.

[0015] Optionally, the included angle between the rotating rod and the rotating head is 90°.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention adds a pedal to the end of the rotating rod away from the rotating head. When the user cannot turn it by hand, the pedal is removed, the rotating rod is inserted into the insertion slot, and the limiting block is inserted into the limiting slot. Then, the pulling block is released, and the elasticity of the elastic element drives the locking block to slide until it is inserted into the locking hole on the limiting block, thus completing the stable installation of the pedal. The user can then directly step on the pedal to continue turning the bolt, which reduces the chance of foot slippage and improves installation efficiency. Attached Figure Description

[0025] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, solution, and effects of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0026] This application discloses an auxiliary device for installing a spare tire in a new energy vehicle, as shown in the following embodiments. Figure 1 and Figure 2 The spare tire installation auxiliary device includes a rotating rod 1, a rotating head 2, and a pedal 3. One end of the rotating head 2 has a slot 21. One end of the rotating rod 1 is integrally formed with the other end of the rotating head 2. Both the rotating head 2 and the rotating rod 1 are cylindrical, and the angle between the rotating head 2 and the rotating rod 1 is 90°. The pedal 3 is a rectangular plate, and the pedal 3 is installed at the end of the rotating rod 1 away from the rotating head 2. The pedal 3, the rotating rod 1, and the rotating head 2 are all on the same plane. Thus, when the user cannot tighten the bolt, the pedal 3 can be installed, and the user can continue to tighten the bolt by stepping on the pedal 3, reducing slippage.

[0027] Furthermore, the slot 21 is a hexagonal slot, which is compatible with the tire bolt; in addition, a rectangular receiving slot 31 is provided on one side of the pedal 3, which can increase the contact area between the user's shoe and the pedal 3, and restrict the movement of the shoe, reducing the chance of the shoe moving out of the pedal 3.

[0028] Reference Figure 2 , Figure 3 and Figure 4 A base 4 is fixedly installed on the side of the pedal 3 away from the receiving groove 31. A insertion groove 41 is provided in the middle of the end of the base 4 near the rotating rod 1. The end of the rotating rod 1 away from the rotating head 2 is inserted into the base 4 through the insertion groove 41. A locking component 5 is installed in the base 4. The locking component 5 includes a limiting block 51. The cross-section of the limiting block 51 is polygonal. In this embodiment, the cross-section of the limiting block 51 is quadrilateral. The limiting block 51 is fixedly installed on the end of the rotating rod 1 away from the rotating head 2. A limiting groove 42 is provided at the bottom of the insertion groove 41. The limiting groove 42 extends in the extending direction of the insertion groove 41. The shape of the limiting groove 42 is adapted to the shape of the limiting block 51. The limiting block 51 is inserted into the base 4 through the limiting groove 42, thereby restricting the rotation of the rotating rod 1.

[0029] The locking assembly 5 also includes a locking element, which includes a locking block 52 and a pull rod 53. A sliding cavity 43 is provided inside the base 4, and the sliding cavity 43 communicates with the limiting groove 42. The locking block 52 is slidably installed inside the base 4 through the sliding cavity 43, and the sliding direction of the locking block 52 is perpendicular to the insertion direction of the limiting block 51. A locking hole 511 is provided on the limiting block 51 corresponding to the position of the locking block 52. One end of the locking block 52 extends into the limiting groove and passes through the locking hole 511, and the other end is fixedly connected to a connecting block 54. The cross-sectional area of ​​the connecting block 54 is larger than that of the locking block 52. The connecting block 54 is slidably installed inside the base 4 through the sliding cavity 43. One end of the pull rod 53 is fixedly installed in the middle position of the connecting block 54, and the other end extends out of the base 4 and is fixedly installed with a pulling block 55. The cross-sectional area of ​​the pull block 55 is larger than that of the pull rod 53, so the user can drive the locking block 52 to move by pulling or pushing the pull block 55, thereby locking or unlocking the limiting block 51. The part of the pull rod 53 inside the sliding cavity 43 is fitted with an elastic element 56, which can be a spring, elastic rubber, etc. In this embodiment, the elastic element 56 is a spring. The two ends of the elastic element 56 are fixedly connected to the connecting block 54 and the groove wall of the sliding cavity 43, respectively. When the locking block 52 leaves the locking hole 511, the elastic element 56 is in a compressed state. Therefore, when the limiting block 51 is inserted into the limiting groove 42, releasing the pull block 55 can drive the locking block 52 to be inserted into the locking hole 511 by the reset action of the elastic element 56, thus completing the locking of the limiting block 51.

[0030] Specifically, the sliding cavity 43 is created by first opening a groove from the outer side wall of the base 4 inward, then installing the locking component, and finally covering the groove opening of the sliding cavity 43 with a cover plate.

[0031] The implementation principle of the auxiliary device for installing a spare tire for a new energy vehicle in this embodiment is as follows: When installing the spare tire of a new energy vehicle, first insert the bolt into the slot 21 of the rotating head 2, then the user first turns the rotating rod 1 by hand until it can no longer be turned, then remove the pedal 3, insert the rotating rod 1 into the insertion slot 41, and the limiting block 51 is inserted into the limiting slot 42. Then, release the pulling block 55, and the locking block 52 will be driven into the locking hole 511 by the reset action of the elastic element 56, thus locking the limiting block 51 and locking the pedal 3. Then the user can step on the pedal 3 to continue tightening the bolt. In this process, since the user does not need to step on the arc surface of the rotating rod 1, the foot slippage is reduced and the installation efficiency is improved.
