Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0068] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices or methods consistent with some aspects of the present invention.

[0069] Embodiment 1

[0070] Referring to Figure 1-13 a rapid installation and disassembly bracket for a power battery shown, the bracket includes: a main beam frame 2, a secondary beam frame 3, and two constraint side plates 4. Among them, the main beam frame 2 is connected to the vehicle frame, a power battery 1 is arranged inside the secondary beam frame 3, the length of the secondary beam frame 3 extends along with the length of the power battery 1, and the width of the secondary beam frame 3 extends along with the width of the power battery 1.

[0071] A plurality of first magnetic attachments 23 are arranged on the top surface of the main beam frame 2, and a plurality of second magnetic attachments 32 are arranged on the bottom surface of the secondary beam frame 3, and the second magnetic attachments 32 are respectively arranged corresponding to the first magnetic attachments 23 one by one, and can be quickly attracted and locked to each other, and can be quickly separated by translation. Among them, the main beam frame 2 includes: two main beams 21, two main cross beams 22; the two main beams 21 are arranged parallel to each other, the two main cross beams 22 are arranged parallel to each other, and the two main beams 21 and the two main cross beams 22 are connected to form a rectangular frame. The secondary beam frame 3 includes: two slide rail secondary beams 31, two slide rail secondary cross beams 34, the two slide rail secondary beams 31 are arranged parallel to each other, the two slide rail secondary cross beams 34 are arranged parallel to each other, and the two slide rail secondary beams 31 and the two slide rail secondary cross beams 34 are connected to form a rectangular frame. The rectangular frame is a rectangle or a square, or the corners of the rectangular frame are chamfered to form a polygon.

[0072] A plurality of first magnetic attachments 23 are respectively arranged on the top surface of the main beam 21, and a plurality of second magnetic attachments 32 are respectively arranged on the bottom surface of the slide rail secondary beam 31.

[0073] In this embodiment, the first magnetic attachments 23 are arranged as four, and the four first magnetic attachments 23 are arranged in mirror symmetry on the top surfaces of the two main beams 21; the second magnetic attachments 32 are arranged as four, and the four second magnetic attachments 32 are arranged in mirror symmetry on the bottom surface of the slide rail secondary beam 31, and the first magnetic attachments 23 and the second magnetic attachments 32 on the same left and right side are arranged corresponding to each other.

[0074] It should be noted that: the first magnetic attachments 23 and the second magnetic attachments 32 are not only arranged as four, but can also be increased or decreased. The first magnetic attachments 23 and the second magnetic attachments 32 are not limited to the shapes shown in the drawings, and can be circular, rectangular, square, trapezoidal or polygonal, etc.

[0075] Two constraint side plates 4 are respectively arranged on the outer side surfaces of the two main beams 21, and the two slide rail secondary beams 31 drive the power battery 1 to slide between the two constraint side plates 4.

[0076] Each constraint side plate 4 is provided with four elastic positioning structures. The elastic positioning structure includes: a through groove 41, a compression spring 42, a ball 43 and an adjusting screw 44; the extending direction of the through groove 41 is communicated with the outer wall surface and the inner wall surface of the constraint side plate 4. The inner cavity wall of the through groove 41 adjacent to the inner wall surface of the constraint side plate 4 is an arc inner cavity wall. The arc inner cavity wall of the through groove 41 wraps the ball 43, and the diameter of the ball 43 is larger than the diameter of the arc inner cavity wall of the through groove 41. The inner cavity wall of the through groove 41 adjacent to the outer wall surface of the constraint side plate 4 is provided with internal threads, and the adjusting screw 44 is detachably connected with the internal threads of the through groove 41; the compression spring 42 is pressed between the adjusting screw 44 and the ball 43. A chute 311 is arranged on the outer side wall of the slide rail secondary beam 31. When the slide rail secondary beam 31 slides with the constraint side plate 4, the ball 43 rolls in the chute 311, and the two slide rail secondary beams 31 can drive the power battery 1 to slide between the two constraint side plates 4. When the roller 312 is embedded into the groove 211, the chute 311 arranged on the slide rail secondary beam 31 presses the ball 43 downward through the weight of the power battery 1 to slide onto the chute 311, and the ball 43 presses the compression spring 42, so that the secondary beam frame 3 is more tightly and firmly arranged on the main beam frame 2.

[0077] The front end of the main beam frame 2 further includes: two limit baffles 24, two buffer springs 25, and two anti-vibration gaskets 26. The two limit baffles 24 are respectively arranged at the front end of a main beam 21, and the two limit baffles 24 are located on the same surface; the two buffer springs 25 are respectively connected with a limit baffle 24, and each buffer spring 25 is located on the inner side above the main beam 21: an anti-vibration gasket 26 is arranged at the end of each buffer spring 25 far away from the limit baffle 24. When the front ends of the two slide rail secondary beams 31 are respectively in close contact with the anti-vibration gaskets 26, the outer side surface of the main cross beam 22 adjacent to the limit baffle 24 is flush with the outer side surface of the slide rail secondary cross beam 34 adjacent to the limit baffle 24. The first magnetic attachment of the main cross beam 22 and the second magnetic attachment of the slide rail secondary cross beam 34 are correspondingly attracted to each other to ensure magnetic attraction and fitting. The buffer springs 25 and the anti-vibration gaskets 26 connected to the limit baffles 24 play a role in preventing vibration and generating noise during the movement of the vehicle.

[0078] On the top surface of each main beam 21, there are three grooves 211. The three grooves 211 gradually decrease in size from the end near the buffer spring 25 to the end far from the buffer spring 25. On the bottom surface of each slide rail secondary beam 31, there are three rollers 312. The three rollers 312 gradually decrease in size from the end near the buffer spring 25 to the end far from the buffer spring 25. The gradually decreasing setting of the three grooves 211 and the three rollers 312 is beneficial for firm clamping during embedding, and is also beneficial for the process of pushing and pulling out, so that the rollers 312 will not be embedded when they reach the corresponding set grooves 211, ensuring smoother sliding.

[0079] In this embodiment, the changes in the three grooves 211 and the three rollers 312 are changes in radial thickness. As Figure 10 , 11 , the groove 211 near the buffer spring 25 is thicker, and there is a partition between the groove 211 far from the buffer spring 25 and the restraint side plate 4. A1 > B1 > C1, and so on, gradually narrowing one by one.

[0080] As Figure 6 , 7 , the roller 312 near the buffer spring 25 is thicker, and the roller 312 far from the buffer spring 25 is farther away from the restraint side plate 4. A > B > C, and so on, gradually narrowing one by one.

[0081] It should be noted that: the sizes of the grooves 211 and the rollers 312 can be set to increase or decrease according to the size of the power battery 1.

[0082] In this embodiment, the groove 211 is V-shaped, which is beneficial for clamping and fixing the roller 312, and also prevents debris from accumulating at the bottom of the groove, affecting the contact surface where the roller 312 is stuck in the groove 211. It should be noted that: the V-shape shown here Figure 13 is not limited to the V-shape, such as trapezoid, ellipse, semi-circle, etc., and all shapes that can achieve this effect are included.

[0083] In this embodiment, six grooves 211 are provided, and the six grooves 211 are symmetrically arranged in a mirror image on the top surfaces of the two main beams 21; six rollers 312 are provided, and the six rollers 312 are symmetrically arranged in a mirror image on the bottom surface of the slide rail secondary beam 31. The grooves 211 and the rollers 312 on the left and right sides of the same side are correspondingly arranged. It should be noted that: the number of grooves 211 and rollers 312 is not limited to six, and can be increased or decreased according to requirements.

[0084] Two anti-vibration cushion strips 33 are respectively arranged on the bottom surface of a slide rail secondary beam 31, and each anti-vibration cushion strip 33 is provided with holes for the rollers 312 and the second magnetic attachments 32 to pass through. The surface of the second magnetic attachment 32 is flush with the surface of the anti-vibration cushion strip 33 to ensure magnetic attraction and fitting. It should be noted that: the two anti-vibration cushion strips 33 are not limited to being arranged on the bottom surface of the slide rail secondary beam 31, and can also be arranged on the bottom surface of the slide rail secondary cross beam 34: they can also be arranged on the top surface of the main cross beam 22.

[0085] A handle 313 is provided at the rear end of each slide rail secondary beam 31 away from the buffer spring 25.

[0086] The realization of a quick installation and disassembly bracket for a power battery includes the following steps:

When the front end of the slide rail secondary beam 31 is in close contact with the anti-vibration gasket 26, drive the roller 312 to embed into the groove 211.

[0090] Among them, during the process of the secondary beam frame 3 sliding and pushing into the main beam frame 2, the ball 43 rolls in the chute 311. During the process of the secondary beam frame 3 sliding and pulling out from the main beam frame 2, the ball 43 rolls in the chute 311, and the two slide rail secondary beams 31 can drive the power battery 1 to slide between the two constraint side plates 4.

[0091] In this embodiment, the first magnetic attachment 23 and the second magnetic attachment 32 are permanent magnets or electromagnets. When the first magnetic attachment 23 and the second magnetic attachment 32 are electromagnets, the presence or absence of magnetism can be controlled by energizing or de-energizing; when the first magnetic attachment 23 and the second magnetic attachment 32 are permanent magnets, a constant magnetism can be maintained without power supply.

[0095] When the power battery 1 needs to be quickly installed, push the handle 313, and push the secondary beam frame 3 into the main beam frame 2 from the back end far away from the buffer spring 25. When the front end of the slide rail secondary beam 31 is in close contact with the shock-proof gasket 26, the shock-proof cushion strip 33 provided on the top surface of the main cross beam 22 fits with the bottom surface of the slide rail secondary cross beam 34, and the first magnetic attachment 23 and the second magnetic attachment 32 adsorb each other, thus forming a quick lock;
