[0032] According to a first aspect of the utility model, a vehicle bolt is provided, which is used for connecting an air conditioning box and a firewall. Figure 2 As shown, the vehicle bolt in this embodiment is formed with a main body, and a threaded portion 10 and a spline portion 12 are respectively formed at both ends of the main body in the length direction. When the vehicle bolt is used, the spline portion 12 is extended to the inside of the air-conditioning box, and the threaded portion 10 is matched with the fastening nut outside the firewall to achieve the connection between the air-conditioning box and the firewall. In the following, the specific structure of the above-mentioned parts of the vehicle bolt according to the utility model will be described in detail.

[0033] In this embodiment, if Figure 2As shown, the main body is formed into a columnar structure, and an annular boss 11 is formed on its outer side wall. The annular boss 11 is located in the middle of the length direction of the main body, that is, the threaded portion 10 and the spline portion 12 are respectively arranged at both ends of the annular boss 11. It should be noted that there is no specific restriction on the position and outer diameter of the annular boss 11, which should be determined comprehensively according to actual conditions such as the length of the internal connection hole of the air conditioner box, and the annular boss 11 should protrude from the threaded portion 10 and the spline portion 12 to facilitate the stable connection of the main body.

[0034] Specifically, the threaded portion 10 is formed at the first end in the length direction of the main body, and there are no specific restrictions on the length and pitch of the external thread, which should be determined according to the nut specifications outside the firewall. In addition, the spline portion 12 is formed at the second end in the length direction of the main body, and includes a plurality of grooves 121, which are arranged at intervals along the circumference of the main body, and each of the grooves 121 extends along the length direction of the main body; further, in the axial section of the second end of the main body, each groove 121 is formed into a V-shaped structure. In this way, the spline portion 12 can ensure that the main body does not rotate during the tightening of the nut, and the spline portion 12 can also provide the main body with axial freedom of movement to eliminate the cumulative tolerance of the assembly.

[0035] It should be noted that there is no specific limitation on the number, size and spacing of the grooves 121 . For example, in this embodiment, six grooves 121 are provided so that the spline portion 12 is formed into a hexagonal spline.

[0036] Furthermore, a placement groove 120 is formed around one end of the spline portion 12 away from the threaded portion 10, and a rubber ring is correspondingly sleeved in the placement groove 120. The rubber ring can enter the connection hole inside the air conditioner box along with the spline portion 12, and the rubber ring is in contact with the inner wall of the connection hole, thereby increasing the friction between the spline portion 12 and the connection hole to prevent the bolts from falling off during the transportation of the air conditioner box.

[0037] According to the vehicle bolt of the utility model, a threaded portion 10 and a spline portion 12 are respectively provided at both ends of the main body in the length direction of the vehicle bolt, the threaded portion 10 is correspondingly connected to the firewall, and the spline portion 12 extends to the interior of the air-conditioning box, thereby releasing the restriction on the freedom of the main body along its own length direction. When tightening the bolt, only the main body can be pulled without affecting the air-conditioning box, thereby effectively avoiding the deformation or rupture of the air-conditioning box shell.

[0038] According to a second aspect of the utility model, a vehicle is provided, wherein the vehicle is provided with the vehicle bolt as described above.

[0039] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
