Description

Technical Field

[0001] This utility model belongs to the field of logistics vehicle technology, specifically relating to a new energy shrinkable vehicle. Background Technology

[0002] There are three packaging methods for lithium batteries in new energy vehicles: prismatic hard-shell, pouch, and cylindrical. The prismatic hard-shell type has an outer aluminum shell and can incorporate a safety valve on the individual cell. This valve opens to release pressure when the cell overheats, making it safer than cylindrical and pouch cells. When prismatic cells move between production lines within the facility, transfer trays are required. Due to the high strength and safety of the prismatic cells themselves, the transfer trays do not require inner linings or other protective structures. However, baffles are needed around the perimeter to contain the cells during movement and prevent them from falling out. Existing trays have fixed baffles on all four sides, essentially creating a lidless box structure. These ordinary trays are bulky, cannot be stacked in multiple layers, resulting in high recycling costs, difficult management, and inconvenient operation for workers. Utility Model Content

[0003] To address the aforementioned problems and technical needs, this utility model provides a new energy retractable carrier. The frame of the carrier can be freely expanded and retracted, and the retracted carrier can be stacked in multiple layers for easy recycling and management.

[0004] The technical solution of this utility model is as follows: A new energy retractable carrier includes a tray, a frame, and a folding protective railing. The tray is rectangular, with a frame along its four sides. The area enclosed by the four frames is the cargo area of ​​the tray. A folding protective railing is installed on the outer side of each frame. The folding protective railing can be folded down or unfolded up along the frame direction. The unfolded height of the folding protective railing does not exceed 1 / 3 of the frame length. After unfolding up, the folding protective railing can self-lock and lock, making the folding protective railing perpendicular to the frame and the tray.

[0005] Furthermore, the folding guardrail includes a horizontal bottom bar, a horizontal top bar, and three vertical bars of equal length connected between the horizontal bottom bar and the horizontal top bar. The horizontal bottom bar is fixedly connected to the outside of the frame, and its length is less than the length of the frame. The front end of the horizontal bottom bar is flush with the end of the frame, and there is a gap between the end of the horizontal bottom bar and the other end of the frame. Three bottom hinge seats are vertically provided on the horizontal bottom bar, and the three bottom hinge seats are equidistant. The first hinge seat is flush with the front end of the horizontal bottom bar. The bottom of the horizontal top bar is also provided with three top hinge seats. The upper and lower ends of the three vertical bars are respectively hinged to the three top hinge seats and the three bottom hinge seats.

[0006] Furthermore, the horizontal top rod can simultaneously drive the three vertical rods to swing around the bottom hinge seat, with a swing range of 90°. When the three vertical rods swing downward from the vertical state to the horizontal state, the horizontal top rod, vertical rods and horizontal bottom rod retract in parallel and stick together vertically.

[0007] Furthermore, when the horizontal top rod is fully extended, the front end of the horizontal top rod is aligned with the front end of the horizontal bottom rod, where a first vertical rod is connected. A second vertical rod is connected to the middle of the horizontal top rod, and a third vertical rod is connected near the end of the horizontal top rod. A locking mechanism is provided on the lower surface of the section of the horizontal top rod that extends out of the third vertical rod. By manually controlling the locking mechanism, the third vertical rod and the horizontal top rod can be vertically locked or unlocked.

[0008] Furthermore, the locking mechanism includes a floating plate, a spring, and a positioning plate. The positioning plate is vertically disposed on the side of the third vertical rod and has a positioning hole. The floating plate is disposed above the positioning plate. The upper surface of the floating plate and the horizontal top rod are connected by a spring. A positioning pin protrudes from the lower surface of the floating plate. Under the action of the spring, the positioning pin is engaged in the positioning hole. During the folding action, the floating plate and the horizontal top rod are gripped, the spring is compressed, the positioning pin at the bottom of the floating plate disengages from the positioning hole, and the horizontal top rod is pulled horizontally downwards to fold the three vertical rods simultaneously by 90 degrees, completing the folding. During the unfolding action, the horizontal top rod is first pulled upwards until the locking mechanism is about to approach the third vertical rod. The floating plate and the horizontal top rod are gripped to compress the spring. Then, the guardrail is fully opened to the vertical position, the floating plate is released, the spring returns to its original position, and the positioning pin is engaged in the positioning hole to achieve locking.

[0009] Furthermore, the top horizontal bar, bottom horizontal bar, and three vertical bars are all square tube-shaped bars, and the top hinge seat and bottom hinge seat are at the same height. In the folded state, the lying vertical bars are completely accommodated in the space between the bottom hinge seats, and the locking mechanism is correspondingly engaged in the gap between the end of the bottom horizontal bar and the other end of the frame.

[0010] Furthermore, the upper and lower ends of the vertical rod are connected to the top and bottom horizontal rods by screws, and the tightness of the screws is adjustable. When the vehicle is in the unfolded state, tightening the screws can lock and reinforce the guardrail. When folding is required, loosening the screws allows the guardrail to be folded and folded up.

[0011] Furthermore, the four folding guardrails are respectively set on the same side of the four frames. The folding action of the guardrails requires swing space, so one side of the frame must be left with enough space for the guardrails to fold up and down. Setting each folding guardrail on the same side of the frame can prevent the guardrails on each frame from interfering with and colliding with each other during the folding action.

[0012] Furthermore, the side of the frame is provided with multiple screw holes, and the horizontal bottom bar and the side of the frame are detachably connected by multiple screws. The folding guardrail and the frame are detachably connected, so that if the folding guardrail is damaged during use, it can be replaced quickly and promptly, improving turnover rate.

[0013] Furthermore, the tray is provided with reinforcing ribs and workpiece positioning holes. The reinforcing ribs increase the strength of the tray, and the workpiece positioning holes prevent the battery cell workpiece from sliding.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1) A folding protective railing is set on the edge of the pallet. After folding, the protective railing is attached to the edge, compressing the overall thickness of the pallet to a minimum, so that the folded pallets can be neatly stacked together, facilitating the transfer and retrieval of the carriers; 2) The locking mechanism set on the folding protective railing can be manually controlled to unfold and lock the folding protective railing, or to unlock and retract the unfolded folding protective railing. The action is simple and easy for workers to operate, and both unfolding and retraction can be operated quickly; 3) The edge of the pallet, as well as the horizontal bottom bar, horizontal top bar, and three vertical bars of the folding protective railing, are all square tubes. Square tubes have good stacking stability, making it easy for the carriers to be aligned vertically and placed stably, and the stacked appearance is neat and beautiful. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-7 The diagram shows the new energy retractable carrier of this utility model, including a tray 1, frame 2, and folding protective railings 3. The tray 1 is rectangular, with frame 2 along its four sides. The area enclosed by the four frame 2 is the cargo area of ​​the tray 1. A folding protective railing 3 is installed on the outer side of each frame 2. The folding protective railing 3 can be folded downwards or unfolded upwards along the direction of the frame 2. The unfolded height of the folding protective railing 3 does not exceed 1 / 3 of the length of the frame 2. The tray 1 is provided with reinforcing ribs 11 and workpiece positioning holes 12. The four folding protective railings 3 are respectively set on the same side of the four frame 2. The folding action of the folding protective railing 3 requires swing space. Therefore, one side of the frame 2 must have enough space for the folding protective railing 3 to fold up and down. Setting each folding protective railing 3 on the same side of the frame 2 can avoid interference and collision between the protective railings on the different frames during the folding action.

[0025] The side of the frame 2 is provided with multiple screw holes 21, and the horizontal bottom bar 31 and the side of the frame are detachably connected by multiple screws 312. The folding guardrail 3 and the frame 2 are detachably connected, so that when the folding guardrail 3 is damaged during use, it can be replaced in a timely and quick manner, improving the turnover rate.

[0026] The folding guardrail 3 can self-lock when unfolded upwards, making it perpendicular to the frame 2 and the tray 1. Specifically, the folding guardrail 3 includes a horizontal bottom bar 31, a horizontal top bar 32, and three vertical bars of equal length connected between the horizontal bottom bar 31 and the horizontal top bar 32. The horizontal bottom bar 31 is fixedly connected to the outside of the frame 2. The length of the horizontal bottom bar 31 is less than the length of the frame. The front end of the horizontal bottom bar 31 is flush with the end of the frame 2. There is a gap between the end of the horizontal bottom bar 31 and the other end of the frame. Three bottom hinge seats 311 are vertically provided on the horizontal bottom bar 31. The three bottom hinge seats 311 are equidistant, and the first hinge seat is flush with the front end of the horizontal bottom bar. The bottom of the horizontal top bar 32 is also provided with three top hinge seats 321. The upper and lower ends of the three vertical bars are respectively hinged to the three top hinge seats 321 and the three bottom hinge seats 311. The horizontal top rod 32 can simultaneously drive the three vertical rods to swing around the bottom hinge seat with a swing range of 90°. When the three vertical rods swing downward from the vertical state to the horizontal state, the horizontal top rod 32, the vertical rods and the horizontal bottom rod 31 retract in parallel and stick together vertically.

[0027] The top horizontal bar 32, bottom horizontal bar 31, and three vertical bars are all square tubular rods. The top hinge seat 321 and the bottom hinge seat 311 are at the same height. In the folded state, the lying vertical bars are completely accommodated in the space between the bottom hinge seats, and the locking mechanism 4 is correspondingly engaged in the gap between the end of the bottom horizontal bar 31 and the other end of the frame. The square tubular design provides good stacking stability, making it easy for the carriers to be aligned vertically and placed securely, resulting in a neat and aesthetically pleasing appearance after stacking.

[0028] When the horizontal top rod 32 is fully extended, the front end of the horizontal top rod 32 is aligned with the front end of the horizontal bottom rod 31. A first vertical rod 33 is connected here. A second vertical rod 34 is connected to the middle of the horizontal top rod 32. A third vertical rod 35 is connected near the end of the horizontal top rod 32. A locking mechanism 4 is provided on the lower surface of the section of the horizontal top rod 32 that extends out of the third vertical rod 35. By manually controlling the locking mechanism 4, the third vertical rod 35 and the horizontal top rod 32 can be vertically locked or unlocked.

[0029] The locking mechanism 4 includes a floating plate 41, a spring 42, and a positioning plate 43. The positioning plate 43 is vertically disposed on the side of the third vertical rod 35, and a positioning hole 431 is provided on the positioning plate 43. The floating plate 41 is correspondingly disposed above the positioning plate 43. The upper surface of the floating plate 41 is connected to the horizontal top rod 32 by the spring 42. A positioning pin 411 protrudes from the lower surface of the floating plate 41. Under the action of the spring, the positioning pin 411 is engaged in the positioning hole 431. The upper and lower ends of the vertical rod are connected to the horizontal top rod 32 and the horizontal bottom rod 31 by screws 36, and the tightness of the screws 36 is adjustable.

[0030] The operation process of this utility model:

[0031] Folding action: Grip the floating plate 41 and the horizontal top rod 32 tightly, the spring 42 is compressed, the positioning pin 411 at the bottom of the floating plate 41 disengages from the positioning hole 431, pull the horizontal top rod 32 horizontally to fold downwards, and the three vertical rods rotate downwards 90 degrees at the same time to complete the folding.

[0032] Deployment action: First, pull the horizontal top rod 32 upward, and the three vertical rods rotate upward simultaneously. When the locking mechanism 4 at the end of the horizontal top rod 32 is about to approach the third vertical rod 35, grip the floating plate 41 and the horizontal top rod 32 to compress the spring 42. Then, fully open the guardrail to the vertical position, release the floating plate 41, the spring 42 returns to its position, and the positioning pin 411 is inserted into the positioning hole 431 to achieve locking. After locking, tighten each screw 36 for reinforcement.
