Description

Technical Field

[0001] The utility model relates to the technical field of home delivery vehicles, in particular to a home delivery vehicle with a detachable rear trunk. Background Art

[0002] Home delivery vehicles usually refer to vehicles specially used for delivery and door-to-door delivery services. These vehicles mainly serve the express delivery, takeout and e-commerce industries. They are responsible for delivering goods from the merchant's warehouse or transfer station to the address specified by the customer. Generally, when deliverymen deliver takeout, they usually install a box on the back of the electric vehicle to hold the takeout for delivery.

[0003] After searching, it was found that the takeaway boxes used by some deliverymen are installed by adding a bracket to the rear of the electric vehicle, and then fixing the takeaway box on the top of the bracket with straps or ropes. In order to firmly fix the takeaway box, the deliverymen need to use multiple sets of straps or ropes to fix it, which makes disassembly and assembly too troublesome. At the same time, the straps or ropes have a certain elasticity. After long-term use, the elasticity will easily fail, making the straps or ropes loose and unstable. Secondly, the bracket is generally one-piece molded. In order to deliver more orders, some deliverymen may use multiple takeaway boxes. The rear bracket may need to be put forward after being lowered, which affects the deliverymen's driving. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a home delivery vehicle with a detachable rear trunk, comprising an electric vehicle 1, a bracket 5 is fixedly connected to the upper surface of the right end of the electric vehicle 1, and a fixing component 3 is arranged on the upper surface of the bracket 5;

[0030] The fixing assembly 3 includes a bottom plate 32, which is fixedly connected to the upper surface of the bracket 5. The front surface of the bottom plate 32 is slidably connected with a slide bar 1 37, and the front surface of the slide bar 1 37 is fixedly connected with a block 2 33. The rear surface of the top of the block 2 33 is set as an inclined surface to ensure that when the box body 2 is lowered, the inclined surface is actually pushed forward to push the block 2 33. The rear surface of the slide bar 1 37 is fixedly connected with a guide block 36. The guide block 36 is in the shape of a trapezoidal block, and its inclined surface is set on the right surface to ensure that when it moves, the slide bar 2 38 will move left or right along the inclined surface of the guide block 36. The upper surface of the bottom plate 32 contacts with a fixing plate 34, and the upper surface of the fixing plate 34 is fixedly connected with the box body 2. The right surface of the fixing plate 34 is provided with a rectangular groove 1 35, and the front surface of the fixing plate 34 is provided with a rectangular groove 313. The rear side of the top of the block 2 33 contacts the inner wall of the rectangular groove 313.

[0031] Reference Figure 2 , Figure 4 The inner wall of the bracket 5 is elastically connected to the connecting frame 4 through a spring 26. The spring 26 will always pull the connecting frame 4 to move backward through its own elasticity, ensuring that the newly added shape clamping column can be stably clamped, thereby improving stability. The connecting frame 4 is slidably connected to the inner wall of the bracket 5, one end of the spring 26 is fixedly connected to the rear surface of the connecting frame 4, and the other end of the spring 26 is fixedly connected to the inner wall of the bracket 5.

[0032] Reference Figure 3 The outer wall of the slide bar 37 is sleeved with a spring 312, and the spring 312 itself has a certain elasticity. It always pushes the guide block 36 to move backward through its own elasticity to ensure that the rear side of the top of the card block 2 33 is always in contact with the inner wall of the rectangular groove 313 when no external force is applied. One end of the spring 312 is fixedly connected to the inner wall of the bottom plate 32, and the other end of the spring 312 is fixedly connected to the front surface of the guide block 36. A rectangular groove 2 39 is provided on the right surface of the guide block 36. The inner wall of the rectangular groove 2 39 is slidably connected with a slide bar 2 38. The slide bar 2 38 penetrates and is slidably connected to the right surface of the bottom plate 32. The right surface of the slide bar 2 38 is fixedly connected with the card block 1 31. The left surface of the top of the card block 1 31 It is set as an inclined surface to ensure that the box 2 can be lowered smoothly. The left side of the top of the block 31 contacts the inner wall of the rectangular groove 35. The left surface of the guide block 36 is fixedly connected to a rack 311. The left surface of the rack 311 is meshed with a gear 310. The gear 310 is rotatably connected to the inner wall of the bottom plate 32. There are multiple groups of guide blocks 36 and racks 311, and the multiple groups of guide blocks 36 and racks 311 are arranged in a circular array with the center of the gear 310 as the origin. The gear 310 and rack 311 are prior art. When one group of racks 311 moves, it will drive the gear 310 to rotate, and the rotating gear 310 will drive another group of racks 311 to move in the opposite direction, ensuring the synchronization of the movement of multiple groups of racks 311.

[0033] Working principle: when the box 2 needs to be installed during use, it is only necessary to pick up the box 2 and move it above the bottom plate 32, and then put the box 2 down. At this time, the box 2 will drive the fixing plate 34 to move downward and contact the clamping block 2 33, and the fixing plate 34 will push it to move along the inclined surface of the clamping block 2 33, and the clamping block 2 33 will drive the slide bar 1 37 to move, and the slide bar 1 37 will drive the guide block 36 to move, and the guide block 36 will squeeze the spring 1 312, and then the slide bar 2 38 will slide on the inner wall of the rectangular groove 2 39, and move to the right along the inclined surface of the guide block 36, and the guide block 36 will drive the rack 311 to move, and the rack 311 will move. The toothed bar 311 will drive the other set of racks 311 to move through the gear 310, so that the other set of card blocks 1 31 and card blocks 2 33 are matched with the same structure as above, until the top clamping point of the card block 2 33 overlaps with the rectangular groove 313. At this time, the spring 1 312 will push the guide block 36 to move in the opposite direction through its own elasticity, so that the card block 2 33 can be stuck into the inner wall of the rectangular groove 313, and the card block 1 31 will also be stuck into the inner wall of the rectangular groove 1 35 as the guide block 36 moves. In this way, the installation can be successful. When disassembling, you only need to pull the card block 2 33. The subsequent structural matching method is the same as above, and the whole process is quick and convenient.

[0034] If it is necessary to install another box 2, it is only necessary to pull the connecting frame 4, the connecting frame 4 will stretch the spring 2 6, and when the connection distance between the connecting frame 4 and the bracket 5 is extended to a certain extent, the added box 2 can be put on it, and then the connecting frame 4 is loosened. The spring 2 6 will always pull the connecting frame 4 in the opposite direction through its own elasticity to clamp the newly added box 2, thereby increasing stability.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
