Description

Technical Field

[0001] This invention relates to the field of battery installation equipment technology, and more specifically, to a new energy battery pack installation bracket with quick-change function. 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. The new energy vehicles commonly seen in daily life are mostly electric vehicles. Electric vehicles primarily rely on new energy batteries to provide power, and these batteries mainly include three types: NCM ternary lithium batteries, NCA ternary lithium batteries, and lithium iron phosphate batteries.

[0003] New energy batteries are key components of electric vehicles. The secure installation and placement of the battery directly affect its operational reliability. To support the battery, ensure its position, and effectively limit its displacement under various disturbances (such as braking, acceleration, or other dynamic loads) to prevent collisions and interference with adjacent parts, ensuring normal battery operation, the battery mounting bracket must have a reliable structure. Battery brackets vary depending on the battery's size and arrangement. However, existing battery brackets often use angle iron for welding or bolts in conjunction with angle iron for installation. Whether welding or using bolts with angle iron, if the battery pack inside the bracket is damaged, tools are needed to disassemble the bracket for battery replacement. Welding or removing numerous bolts is time-consuming, and bolts also present the problem of not being able to connect tools for rotational operations.

[0004] Therefore, we have launched a new energy battery pack mounting bracket with quick-change function. Summary of the Invention

[0005] The purpose of this invention is to provide a new energy battery pack mounting bracket with quick-change function, which aims to solve the problems in the prior art, where the battery pack mounting bracket is fixedly connected by welding or bolts, requiring tools to disassemble and replace the bracket and battery pack, which is time-consuming, and the bolts may be damaged and unable to be connected to tools for rotation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a new energy battery pack mounting bracket with quick-change function, comprising a support plate and connecting angle irons fixedly connected to both sides of the bottom of the support plate, mounting holes being provided on the bottom plate of the connecting angle irons, fixing components being fixedly connected to both sides of the top of the support plate, cross rods being movably connected to both ends of the fixing components, the cross rods being fixedly connected to the four bottom corners of the mounting plate, and battery components being fixedly connected to both ends of the top of the mounting plate.

[0007] The fixing assembly includes an adjusting screw and limiting components at both ends of the adjusting screw.

One end of the adjusting screw passes through the moving plate and is movably sleeved inside the positioning sleeve on the side wall of the positioning plate. The other end passes out from the positioning sleeve and passes through another set of positioning plates. The end of the adjusting screw is movably sleeved inside the positioning sleeve port on the side wall of the second set of positioning plates.

[0009] Furthermore, when the positioning blocks are engaged with each other, the protrusions at the four corners of the cross groove are respectively engaged with the outer walls on both sides of the cross rod. At this time, the bottom end of the cross rod rests against the top of the adjusting screw.

[0010] Furthermore, a movable cylinder is movably sleeved on the outer wall of one end of the adjusting screw on the top side of the support plate. A limiting plate is fixedly connected to the outer wall of the adjusting screw adjacent to the movable cylinder. An elastic component is wound around the outer wall of the adjusting screw between the movable cylinder and the limiting plate. The two ends of the elastic component are fixedly connected to the side walls between the movable cylinder and the limiting plate, respectively. An installation port is opened on the end side wall of the adjusting screw. A connecting shaft is movably connected between the inner walls of the installation port. A toggle disc is fixedly connected to the outer wall of the end of the connecting shaft. An adjusting rocker arm is fixedly connected to one edge of the outer wall of the toggle disc.

[0011] Furthermore, when the elastic component is in a normal relaxed state, the movable cylinder is movably sleeved on the outer wall of the mounting port and the connecting shaft. At this time, the end of the movable cylinder is in contact with the side wall of the actuating turntable, and the end of the adjusting rocker is set parallel to the adjusting screw.

[0012] Furthermore, a T-slot is provided at the top edge of the support plate corresponding to the adjusting rocker arm. The large-diameter port of the T-slot is located on the side away from the adjusting screw. When the end of the adjusting rocker arm is set vertically downward, it is suspended in the small-diameter cavity of the T-slot. At this time, the positioning blocks on the side wall of the positioning plate and the moving plate are engaged with each other.

[0013] Furthermore, the battery assembly includes a mounting box fixedly connected to both ends of the top of the support plate and heat dissipation strip holes evenly distributed on the side walls of both ends of the mounting box. A buffer plate is fixedly connected to the inner wall of one end of the mounting box, and an adjusting cylinder is fixedly connected to the outer wall of the mounting box on the side away from the buffer plate. The battery pack body is placed on the bottom plate of the mounting box between the adjusting cylinder and the buffer plate. The terminal of the battery pack body passes through the buffer plate and extends to the outside of the mounting box. Limiting grooves are opened on the side wall of one end of the mounting box and on the inner walls of both sides. A protective cover is movably engaged in the limiting groove, and the protective cover seals the top of the battery pack body.

[0014] Furthermore, the regulating cylinder includes a piston cylinder fixedly connected to the outer wall of the mounting box and a pressure relief valve pipe fixedly connected to the side wall of the piston cylinder connection end. A suction valve nozzle is fixedly connected to the top of the piston cylinder connection end. A moving rod is movably provided through the side wall of the piston cylinder connection end. A piston disc is fixedly connected to the end of the moving rod inside the piston cylinder. An isolation plate is fixedly connected to the outer wall of the piston disc. A return spring is wound around the outer wall of the moving rod between the piston disc and the piston cylinder connection end. When the return spring is in a normally relaxed state, the end of the isolation plate is located at the piston cylinder port.

[0015] Furthermore, the other end of the moving rod extends through into the mounting box. Inside the mounting box, the end of the moving rod is fixedly connected to a pressing plate. Auxiliary side plates are fixedly connected to the outer walls of the two ends of the pressing plate away from the moving rod. Flexible pads are evenly spaced and fixedly connected to the opposite side walls of the auxiliary side plates. The auxiliary side plates between the flexible pads have a hollow structure.

[0016] Furthermore, the protective cover includes a housing and a buffer groove opened on the top of the housing. The bottom plate of the buffer groove contains a non-Newtonian fluid. A rubber sealing gasket is provided between the inner walls of the buffer groove above the non-Newtonian fluid. A metal mesh is fixedly connected between the inner walls of the buffer groove at adjacent locations above the rubber sealing gasket.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention proposes a new energy battery pack mounting bracket with quick-change function. Through the setting of fixed components, the distance between the positioning plates at both ends of the adjusting screw on the top side of the support plate and the positioning blocks between the side walls of the moving plate is controlled by the cooperation of the adjusting screw and the moving plate. This achieves the snap-fit ​​control of the cross grooves between the side walls of adjacent positioning blocks at both ends of the adjusting screw. The adjusting screw on the top side of the support plate drives the adjusting screw on the other side to rotate synchronously through the pulley and connecting belt, thereby achieving the synchronous snap-fit ​​control of the cross grooves between the side walls of the positioning blocks at the four corners of the top of the support plate. The cross grooves lock the cross rod to complete the fixation of the mounting plate and battery components. Conversely, the locking is released, which facilitates the quick removal of the mounting plate and battery components from the top of the support plate for quick replacement. This avoids the time-consuming process of disassembling and replacing the bracket and battery pack with tools, and the problem of damaged bolts preventing the connection of tools for rotation operation. It is convenient and quick.

[0019] 2. The present invention proposes a new energy battery pack mounting bracket with quick-change function. Through the setting of an adjusting rocker and a T-slot, the adjusting rocker is deflected based on the connecting shaft until it is parallel to the adjusting screw. A movable cylinder is then used to engage and fix the adjusting screw and the connecting shaft, allowing for rotational control of the adjusting screw using the rocker. After controlling the adjusting screw, the movable cylinder is manually removed from the engagement between the adjusting screw and the connecting shaft. The adjusting rocker is then deflected downwards until its end is vertically suspended within the small-diameter inner cavity of the T-slot. The side wall of the small-diameter inner cavity of the T-slot restricts the adjusting rocker, preventing accidental contact that could cause deflection of the adjusting screw. This avoids affecting the stability of the fixed cross rod at the bottom of the mounting plate, thus fully ensuring the installation stability of the battery components.

[0020] 3. The present invention proposes a new energy battery pack mounting bracket with quick-change function. Through the setting of mounting box and adjusting cylinder, the adjusting cylinder forms negative pressure based on internal air suction. The piston plate and moving rod push the extrusion plate to move and fit against the battery pack body inside the mounting box. The extrusion plate, buffer plate, auxiliary side walls at both ends of the extrusion plate and flexible pads are used to lock and fix the battery pack body. The protective cover plate at the port of the mounting box is used for protection. After the piston cylinder is depressurized by air intake through the pressure relief valve pipe, the extrusion plate resets and releases control over the battery pack body, thereby facilitating the removal of the battery pack body from the mounting box for replacement. This realizes quick and easy disassembly and replacement of the battery pack body. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1 A new energy battery pack mounting bracket with quick-change function includes a support plate 1 and connecting angle irons 2 fixedly connected to both sides of the bottom of the support plate 1. The bottom plate of the connecting angle irons 2 is provided with mounting holes 3.

[0034] To address the issues of existing technologies that use welding or bolts to fix battery pack mounting brackets, which require tools for disassembly and replacement, resulting in time-consuming operations and the inability to connect tools for rotation due to damaged bolts, please refer to [the relevant documentation / reference]. Figures 1-6 The following preferred technical solutions are provided:

[0035] Fixing components 4 are fixedly connected to the top two sides of the support plate 1, and cross rods 5 are movably connected to both ends of the fixing components 4. The cross rods 5 are fixedly connected to the bottom four corners of the mounting plate 6, and battery components 7 are fixedly connected to both ends of the top of the mounting plate 6.

[0036] The fixing component 4 includes an adjusting screw 41 and limiting members 42 disposed at both ends of the adjusting screw 41. A pulley 43 is fixedly connected to the outer wall of the straight rod in the middle of the adjusting screw 41. The adjusting screws 41 on both sides of the top of the support plate 1 are connected to the belt 44 through the pulley 43.

[0037] The limiting component 42 includes a fixed plate 421 fixedly connected to the four corners of the top of the support plate 1 and a positioning plate 422 fixedly connected to one end of the top of the fixed plate 421. A limiting groove 423 is provided on the top of the fixed plate 421 adjacent to the positioning plate 422. A movable plate 424 is movably engaged in the limiting groove 423. A positioning block 425 is fixedly connected to the opposite side wall of the positioning plate 422 and the movable plate 424. A cross groove 426 is provided on the opposite side wall of the positioning block 425. The cross groove 426 is used to engage the cross rod 5 to fix the mounting plate 6. Both ends of the adjusting screw 41 pass through the movable plate 424 and are movably connected to the positioning plate 422.

[0038] The adjusting screw 41 is disposed on the side wall of the positioning plate 422 and the moving plate 424 at the lower end of the positioning block 425. One end of the adjusting screw 41 passes through the moving plate 424 and is movably sleeved inside the positioning sleeve 427 on the side wall of the positioning plate 422. The other end passes out from the positioning sleeve 427 and passes through another set of positioning plates 422. The end of the adjusting screw 41 is movably sleeved inside the port of the positioning sleeve 427 on the side wall of the second set of positioning plates 422.

[0039] When the positioning blocks 425 are engaged, the protrusions at the four corners of the cross groove 426 are engaged with the outer walls on both sides of the cross rod 5. At this time, the bottom end of the cross rod 5 rests against the top end of the adjusting screw 41.

[0040] Specifically, when the battery components 7 at both ends of the top of the mounting plate 6 are damaged, the adjusting screw 41 on one side of the top of the support plate 1 is rotated. After the adjusting screw 41 rotates, it drives the movable plates 424 on the outer walls at both ends to slide along the limiting slide grooves 423. The movable plates 424 drive the positioning blocks 425 away from the positioning plates 422 on the top of the fixed plate 421, so that the positioning blocks 425 between the side walls of the positioning plates 422 and the movable plates 424 are separated from each other. When the adjusting screw 41 rotates, the pulley 43 on the outer wall at its middle part drives the adjusting screw 41 on the other side of the top of the support plate 1 to rotate synchronously through the connecting belt 44, so that the positioning blocks 425 between the side walls of the positioning plates 422 and the movable plates 424 at both ends are separated from each other. 5. They also separate synchronously. After the positioning block 425 separates, the cross rods 5 at the four corners of the bottom of the mounting plate 6 disengage from the locking and locking of the cross grooves 426 on the side wall of the positioning block 425, so that the mounting plate 6 and the battery component 7 can be quickly removed from the support plate 1. Conversely, after the adjusting screw 41 rotates in the opposite direction again, the cross grooves 426 will lock the cross rods 5 and the mounting plate 6, realizing synchronous control of the cross rods 5 at the four corners of the bottom of the mounting plate 6, so as to quickly replace the mounting plate 6 and the battery component 7. This avoids the time-consuming problem of disassembling and replacing the bracket and battery pack with tools, and the problem of damaged bolts that cannot be connected to tools for rotation operation, which is convenient and quick.

[0041] To enhance the installation stability of mounting plate 6 and battery component 7, such as Figures 1-3 , Figure 5 and Figure 6 As shown, the following preferred technical solutions are provided:

[0042] A movable cylinder 411 is movably sleeved on the outer wall of one end of the adjusting screw 41 on the top side of the support plate 1. A limiting plate 412 is fixedly connected to the outer wall of the adjusting screw 41 adjacent to the movable cylinder 411. An elastic component 413 is wound around the outer wall of the adjusting screw 41 between the movable cylinder 411 and the limiting plate 412. The two ends of the elastic component 413 are fixedly connected to the side walls between the movable cylinder 411 and the limiting plate 412, respectively. An installation port 414 is opened on the end side wall of the adjusting screw 41. A connecting shaft 415 is movably connected between the inner walls of the installation port 414. A toggle turntable 416 is fixedly connected to the end outer wall of the connecting shaft 415. An adjusting rocker arm 417 is fixedly connected to one edge of the outer wall of the toggle turntable 416.

[0043] When the elastic component 413 is in a normal relaxed state, the movable cylinder 411 is movably sleeved on the outer wall of the mounting port 414 and the connecting shaft 415. At this time, the end of the movable cylinder 411 is in contact with the side wall of the actuating turntable 416, and the end of the adjusting rocker arm 417 is set parallel to the adjusting screw 41.

[0044] A T-slot 8 is provided at the top edge of the support plate 1 corresponding to the adjusting rocker arm 417. The large-diameter port of the T-slot 8 is located on the side away from the adjusting screw 41. When the end of the adjusting rocker arm 417 is set vertically downward, it is suspended in the small-diameter inner cavity of the T-slot 8. At this time, the positioning block 425 on the side wall of the positioning plate 422 and the moving plate 424 are engaged with each other.

[0045] Specifically, the deflection connecting shaft 415 makes the adjusting rocker arm 417 parallel to the adjusting screw 41. The moving cylinder 411 slides along the outer wall of the adjusting screw 41 under the push of the elastic component 413. The moving cylinder 411 moves to the mounting port 414 and is fitted onto the outer wall of the connecting shaft 415. Then, by holding the adjusting rocker arm 417, the adjusting screw 41 can be rotated. The moving cylinder 411 is used to fit and fix the adjusting screw 41 and the connecting shaft 415, facilitating control of the adjusting screw 41. After the adjusting screw 41 is adjusted, the moving cylinder 411 is held and slid away from the adjusting rocker arm 417. The movable cylinder 411 releases the fitting fixation to the connecting shaft 415. Then, the connecting shaft 415 is driven to deflect by the adjusting rocker arm 417, so that the adjusting rocker arm 417 is perpendicular to the adjusting screw 41, and the end of the adjusting rocker arm 417 is suspended vertically downward in the small-diameter inner cavity of the T-slot 8. The side wall of the small-diameter inner cavity of the T-slot 8 restricts the adjusting rocker arm 417 to prevent the adjusting screw 41 from deflecting due to accidental contact of the adjusting rocker arm 417. This avoids affecting the fixing stability of the bottom cross rod 5 of the mounting plate 6 of the limiting member 42, and fully ensures the installation stability of the battery component 7.

[0046] To facilitate quick replacement of the internal battery of the mounting box 71, such as Figures 6-10 As shown, the following preferred technical solutions are provided:

[0047] The battery assembly 7 includes a mounting box 71 fixedly connected to both ends of the top of the support plate 1 and heat dissipation strip holes 72 evenly distributed on the side walls of both ends of the mounting box 71. A buffer plate 73 is fixedly connected to the inner wall of one end of the mounting box 71. An adjusting cylinder 74 is fixedly connected to the outer wall of the mounting box 71 on the side away from the buffer plate 73. A battery pack body 75 is placed on the bottom plate of the mounting box 71 between the adjusting cylinder 74 and the buffer plate 73. The terminals of the battery pack body 75 pass through the buffer plate 73 and extend to the outside of the mounting box 71. A limiting groove 76 is opened on the side wall of one end of the mounting box 71 and on the inner walls of both sides. A protective cover 77 is movably engaged in the limiting groove 76 and covers the top of the battery pack body 75.

[0048] The regulating cylinder 74 includes a piston cylinder 741 fixedly connected to the outer wall of the mounting box 71 and a pressure relief valve pipe 742 fixedly connected to the side wall of the connecting end of the piston cylinder 741. A suction valve nozzle 743 is fixedly connected to the top of the connecting end of the piston cylinder 741. A moving rod 744 is movably provided through the side wall of the connecting end of the piston cylinder 741. A piston disc 745 is fixedly connected to the end of the moving rod 744 inside the piston cylinder 741. An isolation plate 746 is fixedly connected to the outer wall of the piston disc 745. A return spring 747 is wound around the outer wall of the moving rod 744 between the piston disc 745 and the connecting end of the piston cylinder 741. When the return spring 747 is in a normally relaxed state, the end of the isolation plate 746 is located at the port of the piston cylinder 741.

[0049] The other end of the moving rod 744 extends through into the mounting box 71. The end of the moving rod 744 inside the mounting box 71 is fixedly connected to a pressing plate 748. Auxiliary side plates 749 are fixedly connected to the outer walls of the two ends of the pressing plate 748 away from the moving rod 744. Flexible pads 7410 are evenly spaced and fixedly connected to the opposite side walls of the auxiliary side plates 749. The auxiliary side plates 749 between the flexible pads 7410 have a hollow structure.

[0050] The protective cover 77 includes a housing 771 and a buffer groove 772 opened on the top of the housing 771. A non-Newtonian fluid 773 is contained on the bottom plate of the buffer groove 772. A rubber sealing gasket 774 is provided between the inner walls of the buffer groove 772 above the non-Newtonian fluid 773. A metal mesh 775 is fixedly connected between the inner walls of the buffer groove 772 at adjacent locations above the rubber sealing gasket 774.

[0051] Specifically, after removing the protective cover 77, the battery pack body 75 is placed on the base plate of the mounting box 71 between the auxiliary side plates 749. A portable air pump is connected to the air extraction valve 743 to extract air from the piston cylinder 741. The air pressure inside the piston cylinder 741 decreases, creating a negative pressure. Under the push of the external air pressure, the piston disc 745 moves into the port of the piston cylinder 741 and compresses the return spring 747. The piston disc 745 pushes the moving rod 744 into the mounting box 71. The moving rod 744 pushes the pressing plate 748 to abut against the battery pack body 75. The auxiliary side plates 749 at both ends of the pressing plate 748 are engaged by flexible pads 7410. On both sides of the battery pack body 75, the compression plate 748 pushes the battery pack body 75 to fit against the buffer plate 73 to complete the clamping and fixing, so that the terminal of the battery pack body 75 extends from the opening on the buffer plate 73 to the outside of the mounting box 71. Conversely, when the pressure relief valve pipe 742 on the side wall of the mounting box 71 is unscrewed, the external airflow enters the piston cylinder 741 through the connected pressure relief valve pipe 742. After the air pressure inside the piston cylinder 741 is balanced, the piston disc 745 is reset under the action of the return spring 747, and the compression plate 748 releases the fixing of the battery pack body 75, so that the battery pack body 75 can be taken out from the mounting box 71 for replacement, which is convenient and practical.
