Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1-5 As shown, this utility model provides a battery pack installation structure for a folding electric trailer (hereinafter referred to as trailer), including: a folding vehicle body 10 surrounded by a plurality of X-shaped side brackets 11, the folding vehicle body 10 is provided with a controller 25 and a power supply 15 connected to the controller 25, the folding vehicle body 10 is provided with at least one drive wheel, the drive wheel is electrically connected to the controller 25, the power supply 15 is snapped onto at least one of the X-shaped side brackets 11, the X-shaped side bracket 11 with the power supply 15 is also provided with a battery connector 14 adapted to be plugged into the power supply 15, the battery connector 14 is electrically connected to the controller 25, the power supply 15 can slide along the X-shaped side bracket 11 within a predetermined distance, and the power supply 15 connects or disconnects the battery connector 14 from the power supply 15 by sliding;

[0029] Specifically, the folding vehicle body 10 can be either a convergent type or a bi-fold type. A convergent type means the vehicle body folds from the perimeter towards the center, while a bi-fold type means the vehicle body folds from both ends towards the center. The folding vehicle body 10 is composed of several X-shaped side supports 11. If it is a bi-fold type, 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 with other shapes of supports, such as rectangles. Each X-shaped side support 11 can rotate at its intersection to achieve the change between unfolded and folded states. Since the height of the X-shaped side support 11 changes when folded, to avoid movement conflicts, the column connecting the X-shaped side support 11 can be a telescopic structure or a rotatable adapter rod connecting the X-shaped side support 11 and the column. The adapter rod provides movement space for the X-shaped side support 11 through rotation to achieve folding. Several wheels are provided at the bottom of the folding vehicle body 10. The number of wheels depends on the shape of the vehicle body. For example, if the folding vehicle body 10 is triangular, three wheels can be provided; if it is rectangular, three or more wheels are provided. A rectangular vehicle body preferably has four wheels 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, preferably two wheels at the same end are drive wheels or directly driven by an external motor to facilitate the movement of the trailer. The folding vehicle body 10 also has a controller 25 for controlling the operation of the drive wheels and a power supply 15 for providing power to the drive wheels. The power supply 15 is snapped onto at least one X-shaped side bracket 11. The power supply 15 can be completely removed when needed through the snap-fit ​​mechanism, and multiple power supplies can be installed according to usage requirements. A battery connector 14 connected to the power supply 15 is also provided on the X-shaped side bracket 11 where the power supply 15 is snapped onto. This battery connector 14 is electrically connected to the controller 25 and is used to connect the circuit between the power supply 15 and the controller 25. The connection between the power supplies 15 is such that the power supply 15 can slide along the X-shaped side bracket 11 within a predetermined distance. That is, when the power supply 15 is placed on the X-shaped side bracket 11, it needs to slide a certain distance first. During the sliding process, the power supply 15 is inserted with the battery connector 14, and at the same time, the power supply 15 and the X-shaped side bracket 11 are locked together, so that the power supply 15 is suspended on the X-shaped side bracket 11. When the power supply 15 is removed, it is controlled to slide in the opposite direction to the installation direction, so that the battery connector 14 is disconnected from the power supply 15. At the extreme position, the power supply 15 is disengaged from the X-shaped side bracket 11.

[0030] It should be noted that the wiring is concealed, meaning that all wires are located within the X-shaped side bracket 11 to avoid exposure. Spiral wires can be used when necessary to prevent pulling on the wires when the folding vehicle body is folded. A waterproof cover 27 is also attached to the battery connector 14. When the battery connector 14 is connected to the power source 15, the waterproof cover 27 can be attached to the end of the battery connector 14 away from the power source 15. When the power source 15 is removed, the waterproof cover 27 can be attached to the end of the battery connector 14 connected to the power source 15 to prevent moisture and dust from entering the battery connector 14.

[0031] Furthermore, the X-shaped side support 11 includes two staggered support rods 12, one of which is provided with a limiting member 13. The power supply 15 is engaged with the support rod 12 through the limiting member 13. The limiting member 13 is used to cooperate with the power supply 15 to restrict the movement of the power supply 15 along the thickness direction of the support rod 12.

[0032] Specifically, each X-shaped side bracket 11 includes two support rods 12, which are staggered and can rotate relative to each other at the intersection. Each of the support rods 12 has two spaced-apart limiting members 13 on its upper and lower sides, which correspond to each other. The power supply 15 is engaged with the support rod 12 through the limiting member 13. The limiting member 13 and the power supply 15 cooperate to restrict the movement of the power supply 15 along the thickness direction of the support rod 12. The cooperation between the limiting member 13 and the power supply 15 can also restrict the sliding distance of the power supply 15 along the length direction of the support rod 12. This sliding is the movement used to connect or disconnect from the battery connector 14.

[0033] It should be noted that the limiting member 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 inside the folding vehicle body 10 after installation, the limiting member 13 is set on the support rod 12 located on the inner side relative to the entire folding vehicle body 10. In this case, the power supply 15 is located inside the folding vehicle body 10 when it is engaged with the support rod 12. If it is not desired to affect the storage and loading of the folding vehicle body 10, the limiting member 13 is set on the support rod 12 located on the outer side relative to the entire folding vehicle body 10. In this case, the power supply 15 is located inside the folding vehicle body 10 when it is engaged with the support rod 12. The second snap-fit ​​is located outside the folding vehicle body 10. In this embodiment, it is preferably located on the outer support rod 12. This does not affect the folding of the folding vehicle body 10, nor does it affect the loading of goods on the folding vehicle body 10. The thickness direction of the support rod 12 is as follows: taking the support rod 12 located at the front and rear ends of the folding vehicle body 10 as an example, the thickness direction of the support rod 12 coincides with the front and rear direction of the folding vehicle body 10. Taking the support rod 12 located on the side of the folding vehicle body 10 as an example, the thickness direction of the support rod 12 coincides with the left and right direction of the folding vehicle body 10.

[0034] Furthermore, the back of the power supply 15 is provided with a protrusion 16, the protrusion 16 is provided with a recessed clearance groove 18, and the two end side walls of the clearance groove 18 are respectively provided with sliding grooves 19 with an "L" shaped cross section. The sliding grooves 19 cooperate with the limiting member 13 to restrict the movement of the power supply 15 along the thickness direction of the support rod 12.

[0035] Specifically, a protrusion 16 protruding from the back of the power supply 15 is provided. This protrusion 16 has a recessed clearance groove 18, which is adapted to the support rod 12. When the power supply 15 is installed, the support rod 12 is located in the clearance groove 18. At both ends of the clearance groove 18, there are L-shaped sliding grooves 19. The L-shaped sliding grooves 19 allow the limiting member 13 to enter the sliding groove 19 and, after sliding, restrict the movement of the power supply 15 along the thickness direction of the support rod 12 by cooperating with the sliding groove 19, so that the power supply 15 can be suspended on the support rod 12. The sliding distance can be determined by the length of the sliding groove 19. When the limiting member 13 slides to the limit position in the sliding groove 19, it contacts the side wall of the sliding groove 19. When the power supply 15 is engaged with the support rod 12, the sliding of the power supply 15 is restricted. Conversely, the same applies to disassembly. When the power supply 15 is engaged with the support rod 12, the groove 19 at the end near the battery connector 14 passes through the side wall of the protrusion 16. This allows the limiting member 13 corresponding to the groove 19 at that end to directly enter the groove 19 when the power supply 15 slides along the length of the support rod 12. When the power supply 15 is engaged with the support rod 12 with the limiting member 13, the surface of the protrusion 16 abuts against the surface of the other support rod 12. At this time, the abutment between the protrusion 16 and the support rod 12 prevents the power supply 15 from rotating around the engaged support rod 12 as the axis, ensuring the stability of the power supply 15 when the folded vehicle body 10 is in motion.

[0036] Furthermore, the protrusion 16 is provided with relief recesses 17 on both sides;

[0037] Specifically, when the power supply 15 is engaged with the corresponding support rod 12, the protrusion 16 partially surrounds the support rod 12. This protrusion 16 is located within the movement range of the column connecting the X-shaped side bracket 11. When folding, the column is blocked by the protrusion 16, so that the folding vehicle body 10 cannot be fully folded. To avoid this situation, relief recesses 17 are provided on both sides of the protrusion 16. The relief recesses 17 avoid restricting the movement distance of the column when folding, so that the column is located within the relief recesses 17 when the folding vehicle body 10 is folded, thereby achieving the complete folding of the folding vehicle body 10.

[0038] Furthermore, in this embodiment, a positioning device 20 is movably provided on the side of the power supply 15 that contacts the X-shaped side bracket 11. The positioning device 20 is used to restrict the power supply 15 from sliding along the X-shaped side bracket 11.

[0039] Specifically, since the power supply 15 is movable when it is engaged with the corresponding support rod 12, in order to prevent the power supply 15 from moving on the support rod 12 during use, a positioning device 20 is also provided on the side of the power supply 15 facing the X-shaped side bracket 11. The movable positioning device 20 is used to allow the power supply 15 to slide along the support rod 12 when needed, and to restrict the power supply 15 on the support rod 12 when not needed to prevent it from sliding.

[0040] Furthermore, the positioning device 20 includes: an unlocking member 21 slidably disposed on one side wall of the power supply 15; a positioning member 22 that is convexly connected to the unlocking member 21 is provided on the side of the power supply 15 that contacts the X-shaped side bracket 11; the sliding of the unlocking member 21 drives the extension or retraction of the positioning member 22; and the X-shaped side bracket 11 that contacts the power supply 15 is also provided with a positioning hole 23 that is adapted to the positioning member 22.

[0041] Specifically, the positioning device 20 includes an unlocking member 21 slidably disposed on one side wall of the power supply 15, and a positioning member 22 telescopically disposed within one end of the clearance groove 18. The positioning member 22 is connected to the unlocking member 21. The sliding of the unlocking member 21 can cause the positioning member to extend or retract. At the same time, a positioning hole 23 is also provided on the corresponding support rod 12. When the power supply 15 slides along the support rod 12, the battery connector 14 connects to the power supply 15, and the power supply 15 is engaged with the support rod 12. At this time, the positioning member 22 corresponds to the positioning hole 23, and the positioning member 22 will be inserted into the positioning hole 23. This restricts the power supply 15 from sliding along the length direction of the support rod 12. When it is necessary to disassemble the power supply 15, simply slide the unlocking member 21 to retract the positioning member 22, and then slide the power supply 15 to disengage it from the engagement with the support rod 12.

[0042] It should be noted that the unlocking component 21 is equipped with a spring to keep the positioning component 22 always under force and in the extended state.

[0043] Furthermore, in this embodiment, a plug 26 that is inserted and mated with the battery connector 14 is also provided in one side wall of the power supply 15.

[0044] Specifically, a plug 26 is provided inside one side wall of the power supply 15. When the power supply 15 is engaged with the support rod 12, the plug 26 corresponds to the battery connector 14. When the power supply 15 slides down along the support rod 12, the plug 26 is inserted into the battery connector 14.

[0045] It should be noted that the power supply 15 is also equipped with an external interface for connecting to external electrical appliances to discharge them. It also has a power switch for turning the power output on / off and a charging port for charging the power supply 15. To improve visibility at night, the power supply 15 is equipped with a light source that will glow in low-light environments. The plug 26 of the power supply 15 is also waterproof to prevent leakage when used in rainy weather.

[0046] Furthermore, in this embodiment, the protrusion 16 is also provided with a plurality of weight-reducing grooves 24;

[0047] Specifically, in order to reduce the overall weight of the battery, several weight-reducing grooves 24 are provided on both sides of the protrusion 16. While ensuring that there is enough area to abut against the other support rod 12, the overall weight of the battery can also be reduced.

[0048] In the second embodiment, the power supply 15 is also snapped onto the support rod 12. The difference is that the power supply 15 does not need to slide on the support rod 12. Specifically, the power supply 15 is also provided with a groove 19 for the limiting member 13 to enter. The groove 19 is "I" shaped and has a locking structure inside. The locking structure is used to lock the limiting member 13 after it enters the groove 19, so that the power supply 15 is suspended on the support rod 12. The locking structure has an unlocking function. When needed, the locking can be unlocked manually, and the power supply 15 can be removed from the support rod 12. The unlocking method can be sliding or pressing. In this structure, the battery connector 14 can be manually plugged into the power supply 15.

[0049] In a preferred embodiment, the center of the clearance groove 18 is further provided with a screw clearance hole;

[0050] Specifically, the screw clearance hole is used to avoid the screw at the intersection of the two struts.

[0051] In summary, this application, by setting a battery connector on the folding vehicle body, allows the power supply to be snapped into the X-shaped side bracket, enabling the power supply to connect to the battery connector simultaneously during the snapping process. The power supply can be removed when needed, and since the power supply itself is also a battery compartment that can be used for protection, the need for additional protective structures is eliminated, effectively reducing costs. Furthermore, the power supply is simple, convenient, and stable to disassemble, and its installation does not affect the folding of the vehicle body, demonstrating a reasonable structural design.

[0052] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
