[0029] Based on this, some embodiments of the present application are described in detail in combination with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0030] Please refer to the attached Figure 1 To Attachment Figure 8 A safety belt buckle auxiliary release device provided in an embodiment of the present application includes a bracket 1, a lever arm 2 and a connecting shaft component 3 that hinges the two together, wherein the bracket 1 includes a bracket body 101 and a bracket holding handle 102, the bracket body 101 and the bracket holding handle 102 are arranged at approximately 90 degrees, and the shape of the bracket body 101 can be U-shaped or C-shaped.

[0031] Please refer to Figure 4 In some optional embodiments, the bracket holding handle 102 is connected to the bracket body 101 at the first side 106 of the bracket body 101, and the side opposite to the first side 106 of the bracket body is the second side 107 of the bracket body.

[0032] In some optional embodiments, a bracket lanyard hole 105 may be provided at the end of the bracket holding handle 102, and the user can hang the seat belt auxiliary release device in the car by passing a lanyard through the bracket lanyard hole 105 for easy access at any time.

[0033] Please refer to further Figure 5 A bracket shaft hole 103 is provided on the first side 106 of the bracket body.

[0034] Please refer to Figure 6 In some optional embodiments, the lever arm 2 includes a lever arm holding handle 201 and an extension portion 202, and the lever arm holding handle 201 and the extension portion 202 are arranged at approximately 90 degrees, so as to obtain a maximum lever arm and thus a maximum torque.

[0035] In some optional embodiments, a sliding ring 301 may be provided in the lever arm shaft hole 203 , and when the connecting shaft component 3 passes through the lever arm shaft hole 203 , it contacts the sliding ring 301 , thereby achieving a better sliding effect.

[0036] Please refer to Figure 7 In some optional embodiments, the extension portion 202 is connected to the lever arm gripping handle 201 at the extension portion first end 207 of the extension portion 202, the end of the extension portion 202 opposite to the extension portion first end 206 is the extension portion second end 206, and the extension portion first end 207 is provided with a lever arm shaft hole 203.

[0037] The connecting shaft component 3 can be a metal connecting shaft, which passes through the bracket pivot hole 103 and the lever arm pivot hole 203 at the same time, so that the bracket 1 and the lever arm 2 are hinged at the bracket pivot hole 103 and the lever arm pivot hole 203, and the bracket holding handle 102 and the lever arm holding handle 201 are located on the same side of the bracket body 101, and the second end 207 of the extension part and the bracket holding handle 201 are located on the same side of the first end of the extension part. The user holds the bracket holding handle 102 and the lever arm holding handle 201 at the same time to make the two move relative to each other, thereby driving the second end 207 of the extension part to enter the U-shaped or C-shaped space of the bracket body 101.

[0038] Please refer to Figure 4 In some optional embodiments, the first side 106 of the bracket body is provided with a bracket through hole 104, and the portion between the first end 206 of the extension part and the second end 207 of the extension part can pass through the bracket through hole 104 as a whole. It is understandable that other hinge modes can also be used, such as the hinge mode of the hinge axis of common scissors, which can also realize the hinge of the present application, and the bracket through hole 104 can be omitted to directly realize the hinge, which is not specifically limited here.

[0039] Please refer to Figures 2 to 8 The extension 202 is connected to the lever gripping handle 201 on the outer surface of the extension 202. In some optional embodiments, the second end 207 of the extension is provided with a protrusion 204, and the protrusion 204 is connected to the extension 202 on the inner surface of the extension, and the outer surface of the extension and the inner surface of the extension are separated. The protrusion can further increase the length of the U-shaped or C-shaped space of the bracket body 101 on the basis of the portion of the second end 207 of the extension entering the space, thereby reducing the rotation range required by the user to hold the bracket gripping handle 102 and the lever arm gripping handle 201, thereby saving more effort and improving the use efficiency of the safety belt release auxiliary device.

[0040] In some optional embodiments, the end of the protrusion 204 is also provided with a flexible pad fixing groove 205 for fixing the flexible pad 4, and the flexible pad fixing column 407 of the flexible pad 4 can be directly inserted into the flexible pad fixing groove 205 to fix the flexible pad 4. The flexible pad 4 can further extend the length of the protrusion, further reduce the rotation amplitude required for the user to hold the bracket holding handle 102 and the lever arm holding handle 201, thereby saving more effort and further improving the use efficiency of the seat belt release auxiliary device. In addition, the flexible pad 4 can also protect the seat belt buckle and prevent scratches. Finally, the flexible pad 4 can provide friction resistance, so that the seat belt clip and the seat belt clip auxiliary release device are more tightly connected to prevent slipping.

[0041] See also Figure 5 and Figure 6 The protrusion 204 extends from the inner surface of the extension portion into a U-shaped or C-shaped space between the bracket body 101 .

[0042] Furthermore, the protrusion 204 and the extension portion 202 are arranged at approximately 90 degrees. At this time, the extension direction of the protrusion 204 is approximately parallel to the extension direction of the lever arm holding handle 201, which can maximize the effect of extending the portion of the second end 207 of the extension portion that enters the U-shaped or C-shaped space of the bracket body 101, thereby reducing the rotation range required for the user to hold the bracket holding handle 102 and the lever arm holding handle 201, thereby saving more effort and improving the use efficiency of the seat belt release auxiliary device.

[0043] In some optional embodiments, the bracket shaft hole 103 is disposed at a position away from the end of the first side of the bracket body, wherein the end of the first side of the bracket body terminates the first side of the bracket body. The bracket shaft hole 103 is disposed at the end away from the first side of the bracket body, which can maximize the extension of the lever arm formed by the bracket 1 and the lever arm 2, and saves more effort.

[0044] In some optional embodiments, the length of the lever arm gripping handle 201 is greater than the length of the extension portion 202. Since the user applies force at the end of the lever arm gripping handle 201, a better torque can be obtained with less effort.

[0045] Furthermore, the length of the lever arm gripping handle 201 is comparable to the length of the bracket gripping handle 102, providing a better gripping experience for the user.

[0046] Furthermore, the lever arm gripping handle 201 can be slightly moved away from the bracket gripping handle 102 to be arranged in a more ergonomic arc, which can increase the distance between the lever arm gripping handle 201 and the bracket gripping handle 102, increase the rotation space between the bracket 1 and the lever arm 2, and prevent the space from being too small, causing the seat belt clip to be unable to be opened.

[0047] Directions: See also Figure 3 The bracket 1 and the handle 2 are connected by a connecting shaft component 3, and rotate relative to each other around the connecting shaft component 3; a clamping space is formed between the second side 107 of the bracket body and the flexible pad 4, and the clamping space is reduced by relative rotation of the bracket holding handle 102 and the lever arm holding handle 201 to trigger the switch of the seat belt buckle 5 to open the seat belt buckle.

[0048] When in use, the seat belt buckle 5 is placed in the clamping space, the second side 107 of the bracket body supports the lower surface of the seat belt buckle 5 , and the lower end plane 401 of the flexible pad 4 is aligned with the switch on the seat belt buckle 5 .

[0049] The user can hold the bracket holding handle 102 and the lever arm holding handle 201 inward with one hand and apply force to make the lever arm 2 rotate around the connecting shaft component 3, thereby reducing the clamping space and triggering the switch of the seat belt buckle 5 to release the seat belt.

[0050] 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-mentioned 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-mentioned 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.
