[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Please refer to Figure 1 - Figure 9 , a battery swapping battery compartment for a new energy vehicle provided by an embodiment of the present invention includes a containing box 1 in which a plurality of battery modules 101 are placed. A containing groove 12 is provided in the containing box 1. The two containing grooves 12 are communicated through a plurality of through holes 13. Each battery module 101 is placed in the two containing grooves 12. A wire (not shown in the figure) can pass through the through holes 13 between the two containing grooves 12. It further includes a cover plate 2 and a convex block 11. The cover plate 2 is horizontally slidably connected to the containing box 1. The cover plate 2 includes a sliding part 21 and two folding parts 22. The two folding parts 22 are respectively rotatably connected to the sliding part 21 through a rotating shaft 3. During the rotation stroke of the two folding parts 22 relative to the sliding part 21, each has a flat laying position flush with the sliding part 21 and a folding position perpendicular to the sliding part 21; the convex block 11 is fixedly connected to the containing box 1; during the sliding process of the cover plate 2 relative to the containing box 1, two of the folding parts 22 will respectively rotate from the folding position to the flat laying position through the corresponding linkage assembly 4 until the cover plate 2 slides to abut against the convex block 11. The cover plate 2 and the containing box 1 are locked and fixed through a locking member 6. The linkage assembly 4 includes a sleeve 41 and an extension rod 42. The sleeve 41 is fixedly connected to the convex block 11. A guide groove 5 is provided inside the sleeve 41. The guide groove 5 includes a spiral groove 51 and a straight groove 52 that are communicated with each other; the extension rod 42 is coaxially and fixedly connected to the rotating shaft 3 of the corresponding folding part 22. A ball that is in rolling cooperation with the guide groove 5 is provided on the sleeve 41.

[0030] Working principle: Before connecting the cover plate 2 to the accommodation box 1, both folding parts 22 of the cover plate 2 are in the folding position, enabling the cover plate 2 to be easily transported. Due to the limited arm span of the worker, the two folding parts 22 in the folding position also make the cover plate 2 easier to handle. The worker aligns the sliding part 21 of the cover plate 2 with the sliding groove 14 on the accommodation box 1 and then slides the sliding part 21 onto the accommodation box 1. During the sliding process of the sliding part 21 relative to the accommodation box 1, taking one of the rotating shafts 3 as an example, the ball of the extension rod 42 on the rotating shaft 3 cooperates with the guide groove 5. First, the ball cooperates with the spiral groove 51 of the guide groove 5, causing the extension rod 42 to rotate relative to the sleeve 41. The rotation of the extension rod 42 drives the corresponding rotating shaft 3 to rotate, and then the rotating shaft 3 causes the folding part 22 on the rotating shaft 3 to rotate from the folding position to the flat position. As the sliding part 21 slides further, the ball on the extension rod 42 enters the straight groove 52 from the spiral groove 51. Thereafter, both folding parts 22 on the sliding part 21 are in the flat position relative to the sliding part 21. In this state, the cover plate 2 can still slide horizontally relative to the accommodation box 1 and the sliding part 21 can move vertically. As the cover plate 2 slides further until it aligns with the accommodation box 1, the locking part 6 can lock and fix the cover plate 2 and the accommodation box 1 relative to each other. Thereafter, the accommodation box 1 with the cover plate 2 fixed can be installed on the vehicle to serve as a battery compartment. It is worth mentioning that the rotation of the rotating shaft 3 on the sliding part 21 has damping, so that during the transportation or handling of the cover plate 2, both folding parts 22 can remain in the folding position.

[0031] Compared with the prior art, for a battery compartment for new energy vehicle battery swapping provided by the present invention, after the worker slides the sliding part 21 of the cover plate 2 onto the accommodation box 1 and pushes the sliding part 21 to slide it relative to the accommodation box 1, during the sliding process, both folding parts 22 of the cover plate 2 will switch from the folding position to the flat position. Then, when the sliding part 21 abuts against the convex block 11, the locking part 6 locks and fixes the cover plate 2 and the accommodation box 1. During the transportation of the cover plate 2, both rotating parts of the cover plate 2 are in the folding position. On the one hand, this facilitates the worker for transportation or storage. On the other hand, during the installation process of the cover plate 2 and the accommodation box 1, the two folding parts 22 can automatically open and are locked by the locking part 6, effectively improving the installation efficiency.

[0032] Among them, the guide groove 5 also includes an annular groove 53 connected to the straight groove 52, and two sliders 412 are slidably connected in the annular groove 53, and a first elastic member 413 is arranged between the two sliders 412. Specifically, the first elastic member 413 includes a first spring, and the two ends of the first spring are respectively connected to the two sliders 412. When it is necessary to inspect the battery modules 101 in the two receiving grooves 12 without removing the battery modules 101, the worker first needs to unlock the locking member 6 through the unlocking member 7. After the unlocking is completed, the worker flips a folding portion 22 of the cover plate 2 to rotate it from the flattening station to the folding station. During this process, the ball on the rotating shaft 3 corresponding to the folding portion 22 will abut against one of the sliders 412, and then the slider 412 squeezes the first spring again. When the inspection is completed, the elastic force of the first spring can rotate the rotating shaft 3 and then the folding portion 22 is reset from the folding station to the flattening station again, and then the unlocking member 7 is operated again to disengage it from the locking of the locking member 6 so that the cover plate 2 can be fixed on the receiving box 1 again.

[0033] Among them, both folding parts 22 are provided with a slot 221, and the locking member 6 includes two locking units 61, each locking unit 61 includes a wedge block 611, a second elastic member 612 and a connecting rod 613, the wedge block 611 is vertically slidably connected to the storage box 1, and the wedge block 611 has a locking position that matches the slot 221 on the corresponding folding part 22 and an avoidance position that is stored in the storage box 1 in the sliding stroke relative to the storage box 1; the process of the second elastic member 612 restoring the deformation drives the wedge block 611 to switch from the avoidance position to the locking position; the connecting rod 613 is slidably connected in the storage box 1, and the connecting rod 613 is fixedly connected to the corresponding wedge block 611. Specifically, the second elastic member 612 includes a second spring, one end of the second spring is connected to the wedge block 611, and the second spring The other end is connected to the containing box 1. For example, for one of the locking units 61, after the folding portion 22 of the cover plate 2 is rotated from the folding station to the flattening station, the folding portion continues to move horizontally. During the movement, the folding portion 22 abuts against the wedge block 611, causing the wedge block 611 to disengage from the locking position. During the process of the wedge block 611 disengaging from the locking position, the folding portion 22 can move further, and then the top of the inclined surface of the wedge block 611 abuts against the bottom of the folding portion 22 until the slot 221 of the folding portion 22 is aligned with the wedge block 611. The folding portion 22 is reset to the locking position again under the elastic force of the second spring, and the cooperation between the wedge block 611 and the slot 221 locks and fixes the folding portion 22. The two locking units 61 respectively lock and fix the two folding portions 22, thereby realizing the locking and fixation of the cover plate 2.

[0034] Among them, it includes an unlocking member 7. The unlocking member 7 includes a rotating rod 71 and a rotating lever 74. The rotating rod 71 is rotatably connected in the accommodating box 1. The two ends of the rotating rod 71 are respectively hinged with two sliding rods 72. The other ends of the two sliding rods 72 are respectively connected with the connecting rod 613 through hinge rods 73. Both sliding rods 72 are horizontally slidably connected in the accommodating box 1; the rotating lever 74 is fixedly connected to the middle of the rotating rod 71. The end of the rotating lever 74 far from the rotating rod 71 is fixedly connected with a knob 8; during the unlocking process, the worker rotates the knob 8 to drive the rotating lever 74 to rotate. The rotation of the rotating rod 71 causes the sliding rods 72 at both ends of the rotating rod 71 to extend outwards (the two sliding rods 72 slide horizontally relative to the accommodating box 1). Taking one of the sliding rods 72 as an example, the horizontal sliding of the sliding rod 72 pulls the connecting rod 613 through the hinge rod 73, thereby causing the connecting rod 613 to slide vertically downwards. The vertical movement of the connecting rod 613 drives the corresponding wedge-shaped block 611 to move vertically downwards, thereby causing the wedge-shaped block 611 to disengage from the locking position. The other wedge-shaped block 611 is also unlocked synchronously; it is worth mentioning that the two second springs can be replaced with a torsion spring, and the torsion spring is arranged between the rotating lever 74 and the accommodating box 1 to realize the abutment between the cover plate 2 and the wedge-shaped block 611 and then automatically lock.

[0035] Only some exemplary embodiments of the present invention have been described in the above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
