[0031] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figures 1 to 5 , which is the first embodiment of the utility model, and provides an elastic plug 101

[0036] Specifically, the elastic plug 101 includes a hexagonal base 101a, an anchor 101b fixedly connected to the surface of the hexagonal base 101a, and a notch 101c is formed on the anchor 101b.

[0037] Furthermore, the notch 101c divides the anchor 101b into two halves along the center line.

[0038] When in use, the elastic plug 101 is inserted into the mounting hole 203 of the battery tray 200 , and the anchor 101 b is squeezed by the hole wall to deform the anchor 101 b , shrink toward the notch 101 c , and squeezed into the mounting hole 203 .

[0039] In summary, by inserting the elastic plug 101 into the mounting hole 203 of the battery tray 200, it is achieved that during maintenance, debris and dirt will not enter the mounting hole 203, thereby improving the cleanliness of the mounting hole 203 during subsequent installation.

[0040] Example 2

[0041] Reference Figures 1 to 6 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a mounting unit 100, which solves the problem that the mounting bolts of the battery tray are difficult to align and install.

[0042] Specifically, the mounting unit 100 includes an elastic plug 101 , a claw assembly 102 fixedly connected to the elastic plug 101 , and an unlocking assembly 103 disposed inside the claw assembly 102 .

[0043] Furthermore, the elastic plug 101 includes a hexagonal base 101a, an anchor 101b fixedly connected to the surface of the hexagonal base 101a, and a notch 101c is formed on the anchor 101b;

[0044] The hexagonal base 101a is provided with a through hole.

[0045] Preferably, the claw assembly 102 includes a sliding sleeve 102a fixedly connected to the surface of the hexagonal base 101a, a sliding cylinder 102b movably installed inside the sliding sleeve 102a, a movable groove 102c formed on the surface of the sliding cylinder 102b, and an elastic claw 102d extending from one end of the movable groove 102c.

[0046] Furthermore, the claw assembly 102 is provided with two sets of symmetrical movable grooves 102c.

[0047] More preferably, the unlocking assembly 103 includes a limit seat 103a fixedly connected inside the sliding cylinder 102b, a transmission rod 103b movably connected in a through hole opened in the hexagonal base 101a, a protrusion 103c fixedly connected at one end of the transmission rod 103b, a rotating wrench 103d fixedly connected at the other end of the transmission rod 103b, and a return spring 103e fixedly connected on the surface of the hexagonal base 101a.

[0048] The return spring 103e is not only fixedly connected to the surface of the hexagonal base 101a, but also fixedly connected to the inner wall of the sliding cylinder 102b;

[0049] The rotating hexagonal base 101a can rotate the sliding cylinder 102b together with the return spring 103e that fixes the two together.

[0050] Preferably, the protrusion 103c is rotatably embedded in the limiting seat 103a so that the sliding cylinder 102b cannot be ejected by the return spring 103e;

[0051] The mounting unit 100 is made of plastic with certain strength and elasticity, preferably polycarbonate.

[0052] Furthermore, the battery tray 200 includes a bottom shell 201, an edge seal 202 disposed on the outer surface of the bottom shell 201, a mounting hole 203 opened on the edge seal 202, and a frame G connected to the mounting hole 203 by bolts;

[0053] The mounting unit 100 may be mounted in the mounting hole 203 .

[0054] When in use, the mounting unit 100 is installed in the mounting hole 203. At this time, under the action of the elastic plug 101, it is fixed in the mounting hole 203. At this time, the rotating wrench 103d is rotated to rotate the protrusion 103c out of the limit seat 103a, completing the unlocking of the claw assembly 102, so that the sliding cylinder 102b can be popped out by the return spring 103e. When the battery tray 200 moves, when the sliding cylinder 102b is aligned with the threaded hole, it will automatically pop out under the action of the return spring 103e. When multiple mounting units 100 are popped out, the calibration of the battery tray mounting hole 203 and the threaded hole of the frame is completed. At this time, the mounting units 100 are disassembled in turn, and then the screws are installed in turn, and the screws can be accurately installed.

[0055] In summary, by installing the mounting unit 100, the battery tray mounting hole 203 and the threaded hole of the frame can be conveniently calibrated, which facilitates the installation of the screw, improves the accuracy, and increases work efficiency.

[0056] Example 3

[0057] Reference Figures 1 to 6 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides an elastic claw 102d

[0059] Furthermore, the elastic claw 102d is fixedly connected to the sliding cylinder 102b, and is in a retracted state when in the sliding sleeve 102a. When the return spring 103e ejects the sliding cylinder 102b, the elastic claw 102d will also automatically eject.

[0060] During use, when the sliding cylinder 102b is ejected from the sliding sleeve 102a by the return spring 103e, the elastic claw 102d will also pop out automatically. At this time, the teeth of the elastic claw 102d will be stuck in the threaded hole of the frame G, and the pre-installation of the battery tray is completed. At this time, when the installation unit 100 is rotated and disassembled in sequence, the teeth of the elastic claw 102d will also rotate to scrape off the debris and dirt on the thread of the threaded hole, making it easier to install the screw into the threaded hole, thereby improving the installation accuracy of the screw and improving work efficiency.

[0061] In summary, by disassembling the installation unit 100, the teeth of the elastic claw 102d can simultaneously scrape off the debris and dirt on the thread of the threaded hole, thereby improving the installation accuracy of the screw and improving work efficiency.
