Description

Technical Field

[0001] This invention relates to the field of battery tray technology for new energy electric vehicles, specifically to a battery tray for new energy electric vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels but employ new onboard power devices), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. In new energy vehicles, a battery tray is a tray used to hold the batteries, facilitating their transport and placement within the vehicle.

[0003] CN212648388U discloses a new energy electric vehicle tray. This tray is divided into an upper and lower tray, with two battery housing cavities inside each. This design effectively ensures the battery can be placed entirely within the housing, preventing unnecessary external damage and extending battery life. The upper tray has several inverted T-shaped fixing posts on both sides of its bottom, while the lower tray has rectangular grooves on both sides of its top. A zig-shaped locking block is inserted into the through-hole between the rectangular groove and the lower tray. The upper and lower trays are connected by a star-shaped handle threaded connection via mounting holes on the first and second connecting plates. This design ensures tool-free installation between the upper and lower trays, and the structure is robust, easy to assemble and disassemble, and reduces production costs.

[0004] The above solution still has the following shortcomings in actual use: the upper and lower shells of the battery tray are installed with bolts, which means that external tools are needed to load and unload it. Therefore, it becomes very troublesome when a new energy electric vehicle needs to replace the battery in an emergency. Summary of the Invention

[0005] The purpose of this invention is to provide a battery tray for new energy electric vehicles to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solutions:

[0007] The present invention provides a battery tray for a new energy electric vehicle, comprising a square tray cover and a tray. The tray cover is provided with downward protruding fixing plates around its perimeter, and the lower part of the fixing plates is provided with several round holes.

[0008] The upper part of the tray is provided with a surrounding ring plate. Several fixed locking fasteners are provided around the top of the tray. A fixed vertical spring is provided below the locking fastener. The ring plate passes through the locking fastener and can press down on the vertical spring. Several spherical concave surfaces are provided at the top of the ring plate.

[0009] The top of the locking element has a cylindrical cavity, the spherical concave extends into the cylindrical cavity, the cylindrical cavity has a fixed transverse spring, the front end of the transverse spring has a fixed limiting bead, the rear part of the limiting bead falls into the spherical concave, the fixed buckle plate is inserted between the tray and the ring plate, and the limiting bead is nested with the circular hole.

[0010] As an improvement, the lower part of the locking element is provided with a plate groove, the vertical spring is fixed in the middle of the plate groove, and the ring plate passes through the plate groove.

[0011] As an improvement, the front side of the ring plate is provided with several fixed guide blocks, which slide within the square cavity of the locking member, and the square cavity is connected to the plate groove.

[0012] As an improvement, the ring plate forms a gap with the tray, the fixing plate is inserted into the gap, and the limiting bead extends into the gap.

[0013] As an improvement, the end face of the cylindrical cavity is flush with the inner surface of the ring plate.

[0014] As an improvement, the fixing plate is provided with three round holes, and the tray is provided with three locking fasteners on each circumference.

[0015] As an improvement, the bottom of the tray is provided with a fixed battery separator and a mounting base plate.

[0016] As an improvement, the mounting base plate has a space at the bottom and is provided with several straight slots for installation.

[0017] The advantages of this invention compared to existing technologies are as follows: When the tray cover is placed on top of the tray, pressing the ring plate causes the fixing plate to insert into the gap. The spherical concave surface descends, releasing the obstruction to the rear of the limiting bead. At this point, the fixing plate presses down on the front of the limiting bead, causing it to retract into the cylindrical cavity. This continues until, under the pushing action of the transverse spring, the front of the limiting bead engages in the circular hole. Then, the ring plate is released, and the spherical concave surface covers the underside of the rear of the limiting bead, preventing it from retracting into the cylindrical cavity. This manually completes the locking process, assembling the tray cover and the tray. Pressing the ring plate causes the spherical concave surface to descend, releasing the obstruction to the rear of the limiting bead. Immediately afterward, the tray cover is pulled upward, and the circular hole presses the limiting bead back into the cylindrical cavity. The tray cover is removed when the fixing plate leaves the gap.

[0018] By setting up fixed buckles, ring plates, and locking fasteners, when using this tray to load or unload batteries for new energy electric vehicles, the tray cover can be quickly closed or removed by simply pressing the ring plate manually, thus completing the loading or unloading operation without the need for any other tools, making the operation labor-saving and convenient.

Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0035] This embodiment is combined with the appendix Figures 1 to 8 This paper provides a detailed description of a battery tray for a new energy electric vehicle.

[0036] This embodiment provides a battery tray for a new energy electric vehicle, including a square tray cover 1 and a tray 2. The tray cover 1 is provided with downward protruding fixing plates 3 on all four sides, and the lower part of the fixing plates 3 is provided with several round holes 6.

[0037] The upper part of the tray 2 is provided with a surrounding ring plate 4. Several fixed locking fasteners 5 are provided around the top of the tray 2. A fixed vertical spring 18 is provided at the bottom of the locking fasteners 5. The ring plate 4 passes through the locking fasteners 5 and can press down the vertical spring 18. When the vertical spring 18 is in its natural state, it lifts up the ring plate 4. Several spherical concave surfaces 7 are provided at the top of the ring plate 4.

[0038] The locking element 5 has a cylindrical cavity 8 at its top. The spherical concave surface 7 extends into the cylindrical cavity 8. A fixed transverse spring 9 is installed in the cylindrical cavity 8. A fixed limiting bead 10 is installed at the front end of the transverse spring 9. In its natural state, the transverse spring 9 pushes the limiting bead 10 outward, and the rear part of the limiting bead 10 falls into the spherical concave surface 7. The fixed buckle plate 3 is inserted between the tray 2 and the ring plate 4. The limiting bead 10 is nested and fitted with the circular hole 6. The cylindrical cavity 8, the limiting bead 10, and the circular hole 6 have the same diameter, so that the limiting bead 10 slides in the cylindrical cavity 8 and is engaged in the circular hole 6. The diameter of the transverse spring 9 is smaller than that of the cylindrical cavity 8, so that the top of the spherical concave surface 7 enters the cylindrical cavity 8 without interfering with the spring 9.

[0039] The lower part of the locking member 5 is provided with a plate groove 11, the vertical spring 18 is fixed in the middle of the plate groove 11, and the ring plate 4 passes through the plate groove 11.

[0040] The ring plate 4 has several fixed guide blocks 12 on its front side. The guide blocks 12 slide within the square cavity 13 of the locking member 5, guiding the ring plate 4 to move linearly downwards and preventing horizontal swaying. The square cavity 13 is connected to the plate groove 11. The guide blocks 12 guide the ring plate 4 downwards while preventing the ring plate 4 from shifting horizontally.

[0041] The ring plate 4 and the tray 2 form a gap 14. The fixing plate 3 is inserted into the gap 14. Up to half of the limiting bead 10 extends into the gap 14. When the fixing plate 3 is pulled up, the round hole 6 can smoothly push the limiting bead 10 outward.

[0042] The end face of the cylindrical cavity 8 is flush with the inner surface of the ring plate 4, and the fixing plate 3 can slide smoothly against the end face of the cylindrical cavity 8 and the inner surface of the ring plate 4.

[0043] The fixing plate 3 has three round holes 6, and the tray 2 has three locking fasteners 5 on each circumference. The multiple locking fasteners 5 ensure the security of the lock.

[0044] The bottom of the tray 2 is equipped with a fixed battery separator 16 and a mounting base plate 15. The square area enclosed by the battery separator 16 is used for placing and installing batteries.

[0045] The mounting base plate 15 has a space at its lower part, and the mounting base plate 15 is provided with a number of straight slot holes 17 for installation.

[0046] In practical implementation, firstly, several batteries for new energy electric vehicles are installed on the mounting base plate 15 (bolt connection to straight slot 17), and then the relevant wiring is connected. Then, the tray cover 1 is placed on top of the tray 2, and the ring plate 4 is pressed down, causing the fixing plate 3 to be inserted into the interval 14. The ring plate 4 presses down on the vertical spring 18, and the spherical concave 7 descends, thus releasing the obstruction to the rear of the limiting bead 10. At this time, the fixing plate 3 presses down on the front of the limiting bead 10, causing it to retract into the cylindrical cavity 8 until the circular hole 6 aligns with the port of the cylindrical cavity 8. Then, under the pushing action of the transverse spring 9, the front of the limiting bead 10 is inserted into the circular hole 6. Then, the ring plate 4 is released, and the vertical spring 18 naturally lifts it up. The spherical concave 7 is fitted under the rear of the limiting bead 10, preventing it from retracting into the cylindrical cavity 8. Figure 5 At this point, the locking mechanism is manually completed, and the assembly between tray cover 1 and tray 2 is achieved.

[0047] When it is necessary to open the tray 2, press the ring plate 4, the spherical concave 7 descends to release the obstruction of the rear of the limiting bead 10, and then pull the tray cover 1 directly up. The round hole 6 squeezes the limiting bead 10 to retract it into the cylindrical cavity 8. When the fixing plate 3 leaves the interval 14, the tray cover 1 can be taken out.

[0048] The present invention and its embodiments have been described above. This description is not restrictive, and the actual scope of protection is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope of the claims.
