[0035] See appendix Figure 1 -Appendix Figure 8 An anti-theft mobile trailer device includes a vehicle body 1, a towing arm 2, and a limiting part 3. The vehicle body 1 has an upward-opening operating compartment 11, and a cover 12 for opening or closing the opening of the operating compartment 11 is also installed on the vehicle body 1. The cover 12 can be locked and fixed to the vehicle body 1 after closing the opening of the operating compartment 11. The towing arm 2 is hinged to the vehicle body 1 and has a first position folded onto the vehicle body 1 and a second position unfolded detached from the vehicle body 1. The towing arm 2 is equipped with... There is a trailer connector 21; the limiting part 3 includes a latch lock 31 and a latch 32. The latch 32 is installed on the towing arm 2, and the latch lock 31 is installed on the vehicle body 1. The latch lock 31 has a drive rod 310. The tail end of the drive rod 310 can be movably extended into the operating compartment 11. When the towing arm 2 is in the first position, the latch 32 can be inserted into the latch lock 31 and locked. Moving the tail end of the drive rod 310 can drive the latch lock 31 to release the latch 32.

[0036] Specifically, during use, the towing arm 2 is in the second position. After connecting the vehicle to the trailer hitch 21, the vehicle body 1 can be moved to a suitable location for operation. After use, first disconnect the trailer hitch 21 from the vehicle, then rotate the towing arm 2 to the first position so that the latch 32 is inserted into the latch lock 31 and locked. When it is needed to be used again, the operator must first unlock and open the hatch 12, then reach into the operating compartment 11 and move the drive lever 310 to drive the latch lock 31 to release the latch 32, and finally rotate the towing arm 2 back to the second position.

[0037] In summary, this utility model sets the vehicle body 1 and the towing arm 2 in a hinged relationship, ensuring that the towing arm 2 has a first position folded onto the vehicle body 1 and a second position unfolded detached from the vehicle body 1. This design allows the vehicle body 1 to be reduced in size by folding the towing arm 2 when not in use, thereby reducing the space occupied by the vehicle body 1 and improving the user experience. By setting the latch lock 31 and the latch 32 to work together, the towing arm 2 is locked when it is in the first position. Since the end of the drive rod 310 extends into the operating compartment 11, the compartment cover 12 must be unlocked before the drive rod 310 can be moved to drive the latch lock to release the latch 32. This design prevents criminals from unfolding the towing arm 2 for use, thereby reducing the risk of the vehicle body 1 being stolen and ensuring property security.

[0038] It should be noted that the latch lock 31 is an existing product with various models and types, therefore this utility model does not limit its use; on the other hand, the mobile trailer equipment is existing equipment (see reference for details). Figure 1The device can have a battery (not shown) and a circuit board (not shown) installed inside the vehicle body 1, and a solar photovoltaic panel 14 installed outside the vehicle body 1. After the battery and the solar photovoltaic panel 14 are connected through the circuit board, the solar photovoltaic panel 14 charges the battery to store energy, which is then used as an energy supply terminal. Alternatively, it can be used as a regular trailer for loading goods without the relevant circuit unit. Since there are various types of mobile trailer equipment, this utility model does not limit this. As long as the towing arm 2 and the limiting part 3 structure of this solution are used on the vehicle body 1, they should fall within the protection scope of this application.

[0039] See appendix Figure 6 -Appendix Figure 9 A lock 4 is installed at the opening of the operating compartment 11 on the vehicle body 1. When the cover 12 is flipped to close the opening of the operating compartment 11, the lock 4 can lock or release the cover 12. The management personnel can lock and unlock the cover 12 through the lock 4. The operating compartment 11, the lock 4 and the cover 12 can be locked and unlocked by a door lock structure / box lock structure. The door lock structure / box lock structure is widely used in doors / boxes in daily life. It is a conventional structure and the related technology is very mature. Therefore, it will not be described in detail in this utility model.

[0040] Furthermore, the lock 4 can be a mechanical lock, a combination lock, or an electronic lock for recognizing faces / fingerprints to enrich the unlocking methods. Since there are various types of lock 4, they can be selected and set according to the needs of management personnel, and this utility model does not impose any restrictions on this.

[0041] See appendix Figure 5 -Appendix Figure 8 and attached Figure 10 -Appendix Figure 13The latch lock 31 is an existing product, but most existing latch locks 31 are inconvenient to operate and have poor security. To solve this problem, the latch lock 31 of this utility model includes a cover 311, a base 312, a locking rod 313, and a swing hook 314; the cover 311 is installed on the vehicle body 1 and surrounds the base 312; the base 312 has a movable cavity 3121 inside, and the side wall of the movable cavity 3121 has an insertion port 3122 for connecting to the outside; the locking rod 313 is rotatably installed in the movable cavity 3121, and the locking rod 313 also has a locking head 3132 with a protrusion 3131; the drive rod 310 is rotatably installed in the movable cavity 3121. Inside 21, the drive rod 310 has a notch 3101 at its head end for hooking protrusion 3131, and the tail end of the drive rod 310 can movably pass through the movable cavity 3121 and the cover 311 into the operating chamber 11; there are two swing hooks 314, which are rotatably installed on both sides of the insertion port 3122, and the front sides of the two swing hooks 314 surround each other to form a clamping mouth 3141 corresponding to the buckle 32, and the rear sides of the two swing hooks 314 surround each other to form a clamping mouth 3142 corresponding to the clamp head 3132; a first coil spring 313h is installed at the rotatable connection between the clamp rod 313 and the base 312, and a second coil spring 314h is installed at the rotatable connection between the swing hook 314 and the base 312.

[0042] Specifically, when the traction arm 2 is in the first position, the clamp 3141 clamps and fixes the buckle 32 inside, thus locking the traction arm 2. At this time, the second coil spring 314h deforms and stores energy, and the locking block of the locking rod 313 is inserted into the locking slot 3142 to prevent the two swing hooks 314 from expanding towards each other and causing the buckle 32 to disengage from the clamp 3141. When the drive rod 310 is actuated to drive the notch 3101 to apply pressure to the protrusion 3131, causing the locking rod 313 to swing, the locking block disengages from the locking slot 3142 and the first coil spring 313h... The deformation stores energy, and the two second coil springs 314h release energy and restore it, causing the two hooks 314 to expand each other and enlarge the clamping opening 3141, so that the buckle 32 can disengage from the clamping opening 3141, thereby allowing the traction arm 2 to rotate and switch to the second position for use. At this time, the end of the drive rod 310 is released, and the first coil spring 313h applies pressure to the locking rod 313, causing the locking block to abut against the side wall of the two hooks 314 and unable to reset, while the two hooks 314 maintain their original shape under the action of the two second coil springs 314h.

[0043] After use, when the traction arm 2 is switched back to the first position, the latch 32 enters the socket 3122 and simultaneously abuts against the inner side of the two swing hooks 314, causing the two swing hooks 314 to move closer together, causing the clamping opening 3141 to gradually shrink. When the latch 32 is fully inserted into the clamping opening 3141, the clamping opening 3141 shrinks completely to fix the latch 32. At this time, the first coil spring 313h continues to release energy to drive the locking rod 313 to swing, thereby driving the locking block to re-engage the locking opening 3142 and re-lock the two swing hooks 314, thereby re-locking the traction arm 2 in the first position. At the same time, the swinging locking rod 313 will also apply pressure to the recess 3101 through the protrusion 3131 to drive the drive rod 310 to reset. Therefore, the above structure can realize the fixing or loosening of the traction arm 2, and the operation is simple and convenient.

[0044] On the other hand, since the cover 311 surrounds the base 312 and the lever 313 located outside the operating cabin 11, the lever 313 is in a hidden state, ensuring that criminals cannot move the drive component outside the operating cabin 11 to drive the two hooks 314 to expand each other, preventing criminals from rotating the traction arm 2 to the second position for use, thus improving the safety of use.

[0045] See appendix Figure 5 and attached Figure 12 A third coil spring 310h is installed at the rotatable connection between the drive rod 310 and the base 312. When the drive rod 310 is turned, the third coil spring 310h deforms and stores energy.

[0046] Specifically, under normal circumstances, the third coil spring 310h is in its initial state and drives the notch 3101 to fit the protrusion 3131. When the drive rod 310 is swung, the notch 3101 abuts against the protrusion 3131 and applies pressure to drive the locking rod 313 to swing, while the third coil spring 310h deforms and stores energy. When the drive rod 310 is released, the third coil spring 310h releases energy and restores itself, driving the drive rod 310 so that the drive rod 310 and the locking rod 313 reset synchronously. Therefore, with the design of the third coil spring 310h, the drive rod 310 does not need to be reset by the locking rod 313, which can relieve the pressure of the first coil spring 313h and further improve the ease of operation and service life of the latch lock 31.

[0047] See appendix Figure 2 -Appendix Figure 3 The traction arm 2 is also equipped with a rotatable auxiliary wheel 22, and when the traction arm 2 is in the second position, the auxiliary wheel 22 contacts the ground; the design of the auxiliary wheel 22 can increase the contact points between the vehicle body 1 and the ground, thereby providing support to the vehicle body 1 so that the vehicle body 1 can move more stably.

[0048] See appendix Figure 2 -Appendix Figure 3The auxiliary wheel 22 adopts a trailer outrigger guide wheel, which has a first rotation position and a second rotation position.

[0049] Specifically, when the towing arm 2 is in the first position, the trailer outrigger guide wheel can rotate to the first rotation position and be parallel to the towing arm 2 and in the same straight line direction to avoid protruding; when the towing arm 2 is in the second position, the trailer outrigger guide wheel can rotate to the second rotation position and be perpendicular to the towing arm 2 and in contact with the ground to serve as the contact point between the vehicle body 1 and the ground; therefore, the use of trailer outrigger guide wheels can further reduce the size of the vehicle body 1 when the towing arm 2 is not used, thus improving the user experience.

[0050] It should be noted that trailer outrigger guide wheels are quite common in trailer products and are existing products; therefore, their specific structure will not be described in detail in this utility model.

[0051] See appendix Figure 2 -Appendix Figure 3 The bottom of the vehicle body 1 is also equipped with telescopic support feet 13. By adjusting the telescopic length of the telescopic support feet 13, they can be brought into contact with or removed from the ground.

[0052] Specifically, when the towing arm 2 is in the second position and the vehicle is connected to the trailer connector 21 to tow the vehicle body 1, the telescopic support leg 13 is in a retracted state and away from the ground to avoid obstructing the movement of the vehicle body 1; when the towing arm 2 is in the first position, the operator can put the telescopic support leg 13 against the ground to make the vehicle body 1 park stably and prevent the vehicle body 1 from tipping over.

[0053] It should be noted that telescopic support legs 13 are quite common in products such as cabinets and brackets, and are existing products. Therefore, their specific structure will not be described in detail in this utility model.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
