Therefore, the application is not limited by the specific embodiments disclosed below.

[0029] As shown in Figures 1-5, the utility model provides a kind of battery pack mounting structure of folding electric trailer (hereinafter referred to as trailer), including: the folding car body 10 enclosed by several X-shaped side supports 11, the folding car body 10 is equipped with controller 25 and the power supply 15 connected with the controller 25, the folding car body 10 is equipped with at least one drive wheel, the drive wheel is electrically connected with the controller 25, the power supply 15 is clamped and arranged on at least one X-shaped side support 11, the X-shaped side support 11 equipped with the power supply 15 is also equipped with battery connector 14 adapted to be plugged with the power supply 15, the battery connector 14 is electrically connected with the controller 25, the power supply 15 can slide within predetermined distance along the X-shaped side support 11, the power supply 15 is connected or disconnected with the battery connector 14 by sliding with the power supply 15;

[0030] Specifically, the folding vehicle body 10 can be a converging vehicle body or a folding vehicle body, the converging vehicle body refers to the folding mode of the vehicle body is to converge the middle part of the vehicle body from the side, and the folding vehicle body refers to the folding mode of the vehicle body is to converge the middle part from the front and rear ends, wherein the folding vehicle body 10 is composed of a plurality of X-shaped side supports 11, if it is a folding vehicle body, since the front and rear ends do not need to be folded, the X-shaped side supports 11 at the front and rear ends can be replaced by supports of other shapes, such as rectangular supports. Each X-shaped side support 11 can rotate at its own intersection to change the state of unfolding or folding. Since the height of the X-shaped side support 11 changes when it is folded, in order to avoid motion conflicts, the stand connecting the X-shaped side support 11 can be a telescopic structure or a rotating connection adapter rod between the X-shaped side support 11 and the stand, which provides the movement space of the X-shaped side support 11 through the rotation of the adapter rod to achieve folding. A plurality of wheels are provided at the bottom of the folding vehicle body 10, the number of wheels is determined according to the shape of the vehicle body, such as three wheels for a triangular folding vehicle body, three or more wheels for a rectangular folding vehicle body, and preferably four wheels for a rectangular folding vehicle body to ensure stability and prevent rollover. When there are only three wheels, at least one of them is a drive wheel, i.e. a wheel with a hub motor. If there are four wheels, it is preferred that the two wheels at the same end are drive wheels or are directly driven by an external motor to facilitate driving the trailer to move. The folding vehicle body 10 is also provided with a controller 25 for controlling the operation of the drive wheels and a power supply 15 for providing operating energy to the drive wheels. The power supply 15 is detachably connected to at least one X-shaped side support 11 by clamping, and can be set according to the use requirements. A battery connector 14 connected to the power supply 15 is also provided on the X-shaped side support 11 clamped with the power supply 15. The battery connector 14 is electrically connected to the controller 25, and the battery connector 14 is used to connect the circuit between the power supply 15 and the controller 25. In order to facilitate the connection between the battery connector 14 and the power supply 15, the power supply 15 can slide within a predetermined distance along the X-shaped side support 11, i.e. the power supply 15 needs to slide a certain distance when placed on the X-shaped side support 11. During the sliding process, the power supply 15 is inserted together with the battery connector 14, and at the same time the power supply 15 is clamped with the X-shaped side support 11, so that the power supply 15 is hung on the X-shaped side support 11. When disassembling the power supply 15, the power supply 15 slides in the opposite direction to the installation direction, so that the battery connector 14 is disconnected from the power supply 15, and at the same time the power supply 15 is disconnected from the X-shaped side support 11 at the limit position.

[0031] It should be noted that the wires are hidden wires, that is, the wires are located in the X-shaped side support 11, avoiding the exposure of the wires. The wires can adopt a spiral wire when necessary to avoid pulling the wires when the folding vehicle body is folded. The waterproof cover 27 is clamped on the battery connector 14. When the battery connector 14 is connected with the power supply 15, the waterproof cover 27 is clamped on the end of the battery connector 14 away from the power supply 15. When the power supply 15 is removed, the waterproof cover 27 is clamped on the end of the battery connector 14 connected with the power supply 15, thereby preventing water vapor and dust from entering the battery connector 14.

[0032] Further, the X-shaped side support 11 includes two front and rear staggered cross struts 12, one of which is provided with a limiting piece 13, and the power supply 15 is clamped with the strut 12 through the limiting piece 13. The limiting piece 13 is used to cooperate with the power supply 15 to limit the movement of the power supply 15 along the thickness direction of the strut 12.

[0033] Specifically, each X-shaped side support 11 includes two struts 12, which are staggered and crossed front and rear, and can rotate with each other at the intersection. One of the struts 12 is provided with two limiting pieces 13 spaced apart on each side, and the upper and lower limiting pieces 13 correspond to each other. The power supply 15 is clamped with the strut 12 through the limiting piece 13. The limiting piece 13 cooperates with the power supply 15 to limit the movement of the power supply 15 along the thickness direction of the strut 12. The cooperation of the limiting piece 13 and the power supply 15 can also limit the sliding distance of the power supply 15 along the length direction of the strut 12. The sliding is the movement for connecting or disconnecting the battery connector 14.

[0034] It should be noted that the limiting piece 13 can be determined according to the installation requirements of the power supply 15. For example, if the power supply 15 needs to be located in the folding vehicle body 10 after installation, the limiting piece 13 is arranged on the strut 12 located on the inner side relative to the whole folding vehicle body 10. At this time, the power supply 15 is clamped with the strut 12, which is located in the folding vehicle body 10. If you don't want to affect the folding and loading of the folding vehicle body 10, the limiting piece 13 is arranged on the strut 12 located on the outer side relative to the whole folding vehicle body 10. At this time, the power supply 15 is clamped with the strut 12, which is located outside the folding vehicle body 10. In the embodiment, the strut 12 located on the outer side is preferred, which does not affect the folding of the folding vehicle body 10 and does not affect the loading of the folding vehicle body 10. The thickness direction of the strut 12 is taken as an example, which is located at the front and rear ends of the folding vehicle body 10. The thickness direction of the strut 12 coincides with the front and rear directions of the folding vehicle body 10. If the strut 12 located on the side of the folding vehicle body 10 is taken as an example, the thickness direction of the strut 12 coincides with the left and right directions of the folding vehicle body 10.
