Detailed implementation manners

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0042] Please refer to Figures 1-10, a battery housing for a new energy vehicle provided in this embodiment includes a housing body 1. The housing body 1 is formed by stamping an aluminum plate. A separation component is arranged in the housing body 1. The separation component includes a cooling plate 21 and a baffle 22 fixedly connected to the housing body 1. The cooling plate 21 is arranged at the ventilation opening of the housing body 1 and is fixed to the upper half of the housing body 1. A refrigerating sheet can be arranged inside the cooling plate 21. When relatively humid air contacts the cooling plate 21, the water vapor entrained therein adheres to the cooling plate 21 and falls along the cooling plate 21. The baffle 22 is arranged on the side of the cooling plate 21 away from the ventilation opening and is fixed to the bottom of the housing body 1. The space between the baffle 22 and the housing body 1 is a storage space for the water droplets dripping from the cooling plate 21. The bottom surface of the cooling plate 21 needs to be slightly lower than the bottommost part of the ventilation hole, and the topmost part of the baffle 22 needs to be slightly lower than the topmost part of the ventilation hole, so that there is a certain height difference between the cooling plate 21 and the baffle 22. A plurality of one-way through holes 23 are formed in the housing body 1, and one-way valves need to be arranged in the one-way through holes 23, and their flow direction is from the inside of the housing body 1 to the outside of the housing body 1; A floating bladder 11 is slidably connected to the outside of the housing body 1. The floating bladder 11 vertically slides on the outer surface of the housing body 1 through a connecting member. When the floating bladder 11 receives a certain buoyancy, it moves upward. A sealing component is arranged on the floating bladder 11. The sealing component includes a connecting strip 31 fixedly connected to the floating bladder 11. A sealing plate 32 is fixedly connected to the connecting strip 31. The sealing plate 32 is slidably connected to the housing body 1 and vertically slides on the outside of the housing body 1 through a connecting member to ensure that the sealing plate 32 can block the ventilation holes on the housing body 1 when it moves upward; The housing body 1 is fixedly connected to a mounting plate 13 through a plurality of elastic columns 12. The elastic columns 12 have a certain elasticity and can reduce the impact on the battery inside the housing body 1 when the vehicle shakes.

[0043] A new energy vehicle battery shell stamping system, which is used to prepare the above-mentioned shell body 1, includes a stamping table 41, a stamping head 42 is vertically movably connected to the stamping table 41, and the stamping head 42 is driven by an external driving source. When the driving source stops moving, it maintains the state before power failure. A plurality of first elastic telescopic rods 43 are fixedly connected to the stamping head 42, and the bottom end of each first elastic telescopic rod 43 is fixedly connected to a limited position frame 44, and a cross bar 45 is rotatably connected in the limit frame 44, and a roller is arranged on the cross bar 45 46, by setting the limit frame 44, it is convenient to install the roller 46 at the bottom end of the first elastic telescopic rod 43, wherein the roller 46 can also be driven by other external driving sources, as long as it can be achieved that when the punching head 42 moves down, the roller 46 can move down and mortgage and fix the aluminum plate delivered to the punching position; it also includes a plurality of groups of limit components, which are all arranged on the corresponding limit frames 44; it also includes a plurality of groups of truncation components, which are all arranged on the punching head 42. By arranging the truncation components on the punching head 42, the need for The cutting step is performed first; during stamping, the punching head 42 drives the roller 46 and the cutting component to move downward, and the roller 46 is used to fix multiple positions of the aluminum plate. After the cutting component cuts off the excess part of the aluminum plate, the unlocking component triggers the movement of multiple limit components to unlock the cross bar 45, so that the roller 46 limits the aluminum plate moved by the stamping. When the cutting component is not in contact with the aluminum plate, the roller 46 cannot rotate at the fixed position of the limit component. At this time, the aluminum plate abutted by the roller 46 will not be able to move, so as to ensure that the cutting component moves downward to cut off the excess part of the aluminum plate. After the cutting component is cut, the movement of the cutting component drives the limit component to move and release the fixation with the roller 46. At this time, when the punching head 42 moves downward to stamp the cut plate, the plate movement drives the roller 46 to roll. At this time, the rolling roller 46 can limit the aluminum plate. The device can adjust the contact state between the roller 46 and the aluminum plate according to the specific processing conditions to improve the efficiency of stamping the aluminum plate into the shell body 1.

[0044] In a further embodiment provided by the present invention, the limiting component includes a fixed frame 51 fixedly connected to the limiting frame 44, and an auxiliary plate 52 is fixedly connected in the fixed frame 51; a limiting rod 53 is slidably connected in the auxiliary plate 52, and one end of the limiting rod 53 is fixedly connected with a top plate 54. A fixed disk 55 is fixedly connected to the cross bar 45, and a plurality of limiting holes 56 are formed in the fixed disk 55. The plurality of limiting holes 56 on the fixed disk 55 are arranged in an annular array with the cross bar 45 as the center. A contact spring 57 is fixedly connected between the top plate 54 and the fixed frame 51. The elastic force of the contact spring 57 drives the limiting rod 53 to be in clamping fit with the limiting holes 56. When the limiting rod 53 is stuck in the limiting holes 56 on the fixed disk 55, the fixed disk 55 can no longer rotate. Since the fixed disk 55 and the roller 46 are both fixed on the cross bar 45, when the fixed disk 55 cannot rotate, the roller 46 cannot rotate either, so that the roller 46 can be fixed.

[0045] In a further embodiment provided by the present invention, the cutting-off component includes a rotating plate 61 rotatably connected to the punching head 42, and a cutting-off knife 62 is rotatably connected to the bottom end of the rotating plate 61; a guiding plate 63 is fixedly connected in the punching table 41, and a guiding unit for guiding the movement of the cutting-off knife 62 is arranged on the guiding plate 63. Multiple groups of the cutting-off components can be provided, and two mutually perpendicular cutting-off knives 62 are distributed up and down, so as to cut the aluminum plate into a state of an unfolded view of an open rectangle. The specific setting shape can be referred to the attached Figure 5 specification. By setting the guiding unit, the movement direction of the cutting-off knife 62 can be controlled.

[0046] Further, the guiding unit includes a track groove 71 formed in the guiding plate 63, a guiding rod 72 is fixedly connected to the cutting-off knife 62, and the guiding rod 72 is slidably connected in the track groove 71. The track groove 71 is composed of a vertical groove and a horizontal groove, and is specifically in an L shape. When the roller 46 contacts the aluminum plate, the guiding rod 72 moves in the vertical groove of the track groove 71 until the first elastic telescopic rod 43 is compressed by a certain amount. When the contact force generated during the compression of the first elastic telescopic rod 43 is greater than the friction force between the roller 46 and the aluminum plate, at this time, the guiding rod 72 moves to the bottom end of the vertical groove part of the track groove 71 and is about to enter the horizontal groove of the track groove 71. At this time, the cutting-off knife 62 completes the cutting and moves horizontally.

[0047] In an embodiment further provided by the present invention, the unlocking component includes a side plate 81 fixedly connected thereto. A moving plate 83 is connected to the side plate 81 through a second elastic telescopic rod 82. The moving plate 83 is slidably connected to the cutting knife 62. A trigger rod 84 is fixedly connected to the moving plate 83. During the movement stroke of the trigger rod 84, it contacts the top plate 54. The elastic coefficient of the second elastic telescopic rod 82 is greater than that of the abutting spring 57. Therefore, when the trigger rod 84 contacts the top plate 54 and drives the top plate 54 to move horizontally, the abutting spring 57 provided on the top plate 54 is first stretched. The movement of the top plate 54 drives the limiting rod 53 to separate from the limiting hole 56 on the fixed disk 55. Until one side of the top plate 54 contacts one side of the limiting frame 44, at this time, the resistance of the top plate 54 blocked by the limiting frame 44 increases. At this time, the trigger rod 84 stops synchronously, while the cutting knife 62 continues to move, and the second elastic telescopic rod 82 connected between the moving plate 83 and the side plate 81 is stretched.

[0048] In an embodiment provided by the present invention, a mold frame 91 is also fixedly connected to the stamping table 41. A demolding plate 92 is slidably connected in the mold frame 91. During the up and down movement of the stamping head 42, the demolding plate 92 is driven to move through a transmission component. Before stamping, the top of the demolding plate 92 is on the same plane as the processing table, which is convenient for placing and cutting the aluminum plate. After cutting, under the action of the transmission component, the demolding plate 92 moves down with the downward movement of the stamping head 42, so that the cut aluminum plate is stamped into the shape of the housing body 1. After stamping is completed, the demolding plate 92 moves up again under the action of the transmission component to separate the stamped housing body 1 from the mold frame 91.

[0049] Specifically, the transmission component includes a support column 101 fixedly connected to the bottom of the demolding plate 92. A groove for the support column 101 to slide needs to be provided at the bottom end of the mold frame 91. The bottom end of the support column 101 is fixedly connected with an extension plate 102. A first side rod 103 is fixedly connected to the extension plate 102. A first contact plate 104 is fixedly connected to the first side rod 103. A second side rod 105 is fixedly connected to the first contact plate 104. A second contact plate 106 is fixedly connected to the second side rod 105. The top cover of the stamping head 42 is arranged between the first contact plate 104 and the second contact plate 106.

[0050] Further, a clamping block 111 is fixedly connected to the guiding plate 63, and a clamping unit for fixedly connecting the second contact plate 106 is arranged in the clamping block 111; the clamping unit includes a third elastic telescopic rod 112 fixedly connected in the clamping block 111, one end of the third elastic telescopic rod 112 is fixedly connected with an abutting ball 113, a fixing rod 114 is fixedly connected to the second contact plate 106, and a positioning ball 115 is fixedly connected to the fixing rod 114. After the punching head 42 finishes punching, it will drive the second contact plate 106 to move upward synchronously until the positioning ball 115 on the second contact plate 106 enters the clamping block 111, and the bottom of the positioning ball 115 is supported by the abutting ball 113 on the third elastic telescopic rod 112.

[0051] In the further provided solution of the present invention, a support seat 121 is fixedly connected to one side of the punching table 41, and an aluminum plate roller 122 is installed on the support seat 121. By providing the support seat 121, it is convenient to install the aluminum plate roller 122, and the aluminum plate roller 122 is the feeding system for the entire punching table 41.

[0052] Working principle: When the housing body 1 is manufactured, the aluminum plate roller 122 feeds the material. After the aluminum plate moves onto the punching table 41, the punching head 42 is driven to move downward by starting an external driving source. The punching head 42 moves downward to drive the limiting frame 44 and the roller 46 in the limiting frame 44 to move downward, so as to mortgage and fix the aluminum plate on the punching table 41. When the roller 46 contacts the aluminum plate, the punching head 42 continues to move downward. At this time, the first elastic telescopic rod 43 will be compressed, and when the punching head 42 moves downward, it will drive the cutting knife 62 to move downward synchronously through the rotating plate 61. Moreover, when the cutting knife 62 moves downward, it will also be affected by the track groove 71 until the first elastic telescopic rod 43 is compressed to a certain amount, and the cutting knife 62 will contact the aluminum plate on the punching table 41 and cut it. After the cutting is completed, the cutting knife 62 will move horizontally under the action of the track groove 71 and the guiding rod 72 until the rotating plate 61 connecting the cutting knife 62 and the punching head 42 rotates, and while the cutting knife 62 moves horizontally, the trigger rod 84 connected to the moving plate 83 of the cutting knife 62 will contact the top plate 54 and drive the top plate 54 to move to the side away from the roller 46. The movement of the top plate 54 drives the limiting rod 53 to disengage from the fixed disk 55 until the top plate 54 moves to contact one side of the fixed frame 51. At this time, both the top plate 54 and the trigger rod 84 are restricted by the fixed frame 51 and no longer move, while the cutting knife 62 continues to move under the downward movement of the punching head 42. At this time, the second elastic telescopic rod 82 connecting the moving plate 83 and the side plate 81 of the cutting knife 62 is stretched;

[0053] While the second elastic telescopic rod 82 is being stretched, the stamping head 42 will contact the first contact plate 104 and drive the first contact plate 104 to move downward synchronously. After the first contact plate 104 is pushed downward, the positioning ball 115 on the second contact plate 106 will be disengaged from the two abutting balls 113 in the clamping block 111. At this time, the first contact plate 104 moves downward under the action of gravity and drives the extension plate 102 to move synchronously through the first side rod 103. The movement of the extension plate 102 drives the stripping plate 92 to retract into the mold frame 91 through the support column 101. At this time, the stamping head 42 will slowly abut against the cut aluminum plate and enter the mold frame 91, and finally a complete housing body 1 can be stamped out;

[0054] After stamping is completed, at this time, the external drive source drives the stamping head 42 to move upward. The upward movement of the stamping head 42 will first drive the horizontally moving cutting knife 62 to reset through the rotating plate 61. During the reset process of the cutting knife 62, the second elastic telescopic rod 82 first has a restoring force and then slowly drives the unlocking rod to reset. The reset of the unlocking rod releases the thrust on the top plate 54. The compressed abutting spring 57 has a restoring force and drives the top plate 54 to reset. The reset of the top plate 54 drives the limiting rod 53 to be clamped in the limiting hole 56 on the fixed disk 55 again. It is not until the cutting knife 62 is reset to the position of moving vertically upward that the stamping head 42 contacts the second contact plate 106 and drives the second contact plate 106 to move upward. The upward movement of the second contact plate 106 drives the stripping plate 92 to move upward through the second side rod 105, the first contact plate 104, the first side rod 103, the extension plate 102 and the support column 101, and the stamped housing body 1 in the mold frame 91 can be ejected, which is convenient for blanking of the mold frame 91. At this time, the stamping head 42 continues to move upward, and the compressed first elastic telescopic rod 43 is restored to drive the limiting frame 44 and the roller 46 to separate from the stamping table 41 until the positioning ball 115 on the second contact plate 106 enters the clamping block 111 again and abuts against the two abutting balls 113 in the clamping block 111 to move away. When the positioning ball 115 moves upward and separates from the abutting ball 113, the abutting ball 113 is reset under the action of the third elastic telescopic rod 112 and abuts against the bottom fixing rod 114 of the positioning ball 115.

[0055] Only some exemplary embodiments of the present invention are described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
