Description

Technical Field

[0001] This invention relates to the field of mounting bracket technology, and in particular to a battery module stacked mounting bracket for power supply vehicles. Background Technology

[0002] Power supply vehicles, as core specialized equipment for emergency power supply, field operations, and power repair, are widely used in municipal emergency response, power outage rescue in mines and factories, field engineering construction, and power maintenance. The battery module is the core energy storage component of the power supply vehicle; the rationality, stability, heat dissipation, and ease of maintenance of its installation and fixing structure directly determine the energy storage capacity, operational safety, service life, and maintenance efficiency of the power supply vehicle.

[0003] As various industries continue to increase their demand for high-power, long-range, miniaturized, and highly stable power supply vehicles, the drawbacks of traditional battery installation structures are becoming increasingly apparent, and they can no longer meet the needs of high-end and scenario-based vehicle power supply applications.

[0004] For example, Chinese Patent Publication No. CN216903183U describes a battery module mounting bracket, including battery insulation support wheels, shock-absorbing wheels, snap-on guardrails A and B, layered brackets, and guide rails. The snap-on guardrails A, B, and layered brackets form a frame. Two to four guide rails are laid along the length of the bottom of the frame. Multiple dumbbell-shaped battery insulation support wheels are mounted on the guide rails, with the rims of the battery insulation support wheels higher than the guide rails. Shock-absorbing wheels are located at the bottom of the rectangular frame. The snap-on guardrails A and B are... The battery mounting bracket is connected to the tiered support via snap-fit ​​fasteners. These fasteners are telescopic and have a round hole inside. A spring is installed inside the round hole, and the spring is fitted onto both ends of the snap-fit ​​guardrails A and B. A protrusion is provided on the right end of the fastener, and the protrusion fits into the round hole on the tiered support. The frame consisting of snap-fit ​​guardrails A and B and the tiered support has 2-5 layers. The battery mounting bracket is a multi-layered installation design and can be adjusted according to the size of the battery. Snap-fit ​​guardrails are provided on all four sides of the mounting bracket for easy installation and removal of the battery.

[0005] In existing technical references, batteries can be stacked using multi-component layered brackets. However, with this design, it is inconvenient to self-lock at the vertical stacked connections. When the vehicle encounters bumpy roads and vibrations during transport, the connections may loosen over time, affecting the stability of the stacked battery pack and potentially causing damage. Summary of the Invention

[0006] To solve the above technical problems, the present invention is implemented through the following technical solution:

[0007] A battery module stacked mounting bracket for a power supply vehicle, comprising:

[0008] Base and X-shaped press holder;

[0009] A support assembly includes a rectangular frame and a blower. The rectangular frame is fixedly installed on the top of the base and is hollow. The blower is fixedly installed on the inner side of the rectangular frame. An air pipe connects the air outlet at the bottom of the blower to the bottom of the rectangular frame. A square tube is detachably fixedly installed on the top side of the rectangular frame. A locking screw is threaded on the surface of the square tube. A round hole is opened on the side of the square tube away from the locking screw, and the locking screw passes through the round hole. An X-shaped pressing bracket is detachably fixedly installed on the top of the square tube.

[0010] A stacked mechanism includes a connecting sleeve, a first connecting beam, and a second connecting beam. The connecting sleeve is fitted onto the surface of a square tube. The first connecting beam is fixedly installed on the surface of the connecting sleeve. The second connecting beam is fixedly installed on the surface of the connecting sleeve and close to the first connecting beam. A self-locking caliper is fixedly installed on the outer side of the connecting sleeve and close to the locking screw. A clamping assembly is installed on the surface of the second connecting beam. A support spring is fixedly connected to the inner side of the connecting sleeve. A semi-circular sealing ball is fixedly connected to one end of the support spring near the locking screw. The spherical surface of the semi-circular sealing ball is in contact with one end of the locking screw inserted into the circular hole. The end of the locking screw applies a constant pressure to the semi-circular sealing ball, causing the support spring to elastically deform and the semi-circular sealing ball to move away from the circular hole, separating the semi-circular sealing ball from the circular hole. A flexible sheet is fixedly connected to the inner side of the first connecting beam. A battery support assembly is installed at the bottom of the first connecting beam.

[0011] By installing a slidable connecting sleeve on the outside of the square tube, and combining it with the first connecting beam and the second connecting beam to form a stacked support frame, multiple battery modules can be stacked and installed, achieving a neat stacked arrangement of multiple battery modules. At the same time, the rectangular frame, square tube and blower adopt a modular and detachable assembly structure, which simplifies the disassembly and assembly process, eliminates the need for complex auxiliary tooling, facilitates the assembly, maintenance and replacement of battery modules in the power vehicle, and has extremely strong versatility.

[0012] When the locking screw is tightened, the end of the locking screw presses against the semi-circular sealing ball, causing the support spring to undergo elastic deformation. The semi-circular sealing ball then moves away from the circular hole, releasing the seal on the circular hole.

[0013] Preferably, there are four hair dryers, and the four hair dryers are evenly distributed inside the rectangular frame. The air pipe, the rectangular frame and the square pipe are connected to form an air supply channel.

[0014] Preferably, the square tubes are installed vertically, there are four square tubes, and the four square tubes are evenly distributed on the top side of the rectangular frame, and the locking screws are evenly distributed on the surface of the square tubes.

[0015] When assembling the stacked mechanism with the square tube, the connecting sleeve is placed on the surface of the square tube. When the supporting spring applies an elastic pushing force to the semi-circular sealing ball, the spherical surface of the semi-circular sealing ball is made to fit against the surface of the square tube. As the connecting sleeve, the first connecting beam and the second connecting beam continue to slide down, the semi-circular sealing ball is embedded into the inside of the circular hole, which can be initially positioned. This helps to fix the connecting sleeve and the square tube with the locking screw, making it less likely for the connecting sleeve to shift.

[0016] Preferably, the connecting sleeve is fixedly installed between the connecting sleeve and the square tube by a locking screw, the end of the locking screw extending into the interior of the connecting sleeve. The first connecting beam and the second connecting beam are both hollow. The structural frame composed of the connecting sleeve, the first connecting beam and the second connecting beam is evenly distributed on the surface of the square tube to form a stacked battery module bracket.

[0017] By inserting a locking screw into the round hole, the end of the locking screw compresses the semi-circular sealing ball, and the supporting spring deforms elastically, achieving precise positioning and fixation. At the same time, a self-locking caliper engages the hexagonal end of the locking screw, forming a double anti-loosening limit structure. This solves the problem of traditional bolt structures being prone to loosening, displacement, and falling off under bumpy and vibrating conditions during power vehicle operation. It effectively ensures the firmness of multi-layer battery module installation in complex driving environments, avoids safety hazards caused by battery shaking and displacement, and significantly improves the reliability and service life of the equipment.

[0018] Preferably, the first connecting beam and the second connecting beam are installed on adjacent surfaces on the outside of the connecting sleeve, and both the first connecting beam and the second connecting beam are in communication with the connecting sleeve. The caliper head at the bottom of the self-locking caliper is engaged with the hexagonal head on the outside of the locking screw. The flexible sheet is made of rubber.

[0019] Preferably, the clamping assembly includes a wedge-shaped pusher, a first right-angle plate, and a second right-angle plate. The top end of the wedge-shaped pusher is fixedly installed to the bottom of the second connecting beam. The bottom of the first right-angle plate is fixedly installed to the top of the second connecting beam. The bottom of the second right-angle plate is fixedly installed to the top of the second connecting beam and close to the first right-angle plate. Square guide rods are slidably installed on the surfaces of the first and second right-angle plates. A clamping plate is fixedly installed at the end of the square guide rod. A rubber strip is fixedly connected to the clamping surface of the clamping plate.

[0020] Preferably, the bottom end of the wedge-shaped pusher is inserted between the first right-angle plate and the second right-angle plate, and the first right-angle plate and the second right-angle plate are installed at the same height.

[0021] Preferably, the clamping plate is installed on the inclined surface outside the wedge-shaped pusher, and the rubber strips are evenly distributed on the clamping surface of the clamping plate.

[0022] Preferably, the battery lifting assembly includes a U-shaped lifting tube and a strip pad. The top end of the U-shaped lifting tube is detachably fixed to the bottom of the first connecting beam. The strip pad is fixedly installed at the bottom of the U-shaped lifting tube. A conical support cap is connected to the bottom of the inner side of the U-shaped lifting tube. An air jet hole is opened at the conical surface on the outer side of the conical support cap, with the air outlet of the air jet hole facing upward. A circular pad is fixedly connected to the top end of the conical support cap. The rectangular frame, square tube, connecting sleeve, hollow connecting beam, and U-shaped lifting tube are interconnected to form an integrated built-in air supply duct. Air is concentrated and blown by blowers evenly arranged inside the rectangular frame, utilizing the blower... The fan's blowing power, connected by air pipes, allows gas to enter the hollow rectangular frame through the air pipes. The airflow rises from the square tube, connecting sleeve, hollow connecting beam, and U-shaped support tube, and then sprays upwards from the jet holes on the surface of the conical support cap. This precisely provides directional air cooling to the bottom of the battery module inside the U-shaped support tube, quickly removing the heat generated by the battery during operation, effectively reducing the battery's operating temperature rise, and preventing problems such as high-temperature aging and thermal runaway. This ensures the battery pack operates continuously and stably. At the same time, the air duct is integrated inside the bracket body, eliminating the need to occupy additional space in the power vehicle compartment, simplifying the equipment piping structure, and improving the utilization rate of the compartment space.

[0023] Preferably, the U-shaped support tubes are evenly distributed at the bottom of the first connecting beam, and the U-shaped support tubes are connected to the first connecting beam. The conical support caps are evenly distributed at the bottom of the inner side of the U-shaped support tubes. The strip pads and the circular pads are both made of rubber. The U-shaped support tubes, in conjunction with the strip pads and the circular pads, provide stable support for the bottom of the battery. The evenly distributed conical support caps increase the support points for the bottom of the battery. The wedge-shaped pusher drives the clamping plates on both sides to adaptively clamp the sides of the battery, achieving bidirectional fixed positioning of the battery module. Under the support and guidance of the square guide rod, the symmetrical clamping plates on both sides are more stable. With the frame composed of the multi-connecting sleeve, the first connecting beam, and the second connecting beam, the battery module is compacted by the U-shaped support tubes installed on the first connecting beam. Finally, the X-shaped pressing frame presses down the top battery module to prevent the battery module from shaking, ensuring safety and reliability.

[0024] The rubber strips, flexible sheets, strip pads, and circular pads on the clamping plate can make flexible contact with the battery module, avoiding rigid contact. This effectively buffers the impact and vibration during vehicle operation, prevents rigid collisions, wear, and displacement of the battery module, protects the battery casing and internal cell structure, and improves the safety and protection of battery pack installation.

[0025] Compared with existing traditional battery mounting brackets, the present invention has a compact overall structure design, high integration, excellent adaptability and stability, and combines a stacked adjustment structure, a self-locking fastening structure and an integrated air-cooling heat dissipation structure.

[0026] The overall frame structure is well-organized and clearly hierarchical. Through an X-shaped pressing frame and a multi-layer stacking mechanism, the battery modules are positioned vertically and horizontally in all directions, resulting in a neat and orderly stacked installation with high space utilization. All components are detachable and modular, allowing for flexible addition or removal of stacked layers according to actual usage needs. This adapts to the battery loading requirements of vehicles with different power outputs, offering strong structural expandability and convenient assembly, maintenance, and future upgrades. It possesses extremely high engineering practical value and promising prospects for widespread application.

[0027] The beneficial effects of the technical solution provided by this invention include:

[0028] 1. By installing a sliding connecting sleeve on the outside of the square tube, and combining it with the first connecting beam and the second connecting beam to form a stacked support frame, multiple battery modules can be stacked and installed, achieving a neat stacked arrangement of multiple battery modules. At the same time, the rectangular frame, square tube and blower adopt a modular and detachable assembly structure, which simplifies the disassembly and assembly process, eliminates the need for complex auxiliary tooling, facilitates the assembly, maintenance and replacement of battery modules in the power vehicle, and has extremely strong versatility.

[0029] 2. When assembling the stacked mechanism with the square tube, the connecting sleeve is placed on the surface of the square tube. When the supporting spring applies an elastic pushing force to the semi-circular sealing ball, the spherical surface of the semi-circular sealing ball is made to fit against the surface of the square tube. As the connecting sleeve, the first connecting beam and the second connecting beam continue to slide down, the semi-circular sealing ball is embedded into the inside of the circular hole, which can be initially positioned. This helps to fix the connecting sleeve and the square tube with the locking screw, making it less likely for the connecting sleeve to shift.

[0030] Third, by inserting the locking screw into the round hole, the end of the locking screw compresses the semi-circular sealing ball, and the supporting spring deforms elastically, achieving precise positioning and fixation. At the same time, the self-locking caliper engages the hexagonal end of the locking screw, forming a double anti-loosening limit structure. This solves the problem of traditional bolt structures being prone to loosening, displacement, and falling off under bumpy and vibrating conditions during power vehicle operation. It effectively ensures the firmness of multi-layer battery module installation in complex driving environments, avoids safety hazards caused by battery shaking and displacement, and significantly improves the reliability and service life of the equipment.

[0031] Fourth, by using blowers evenly distributed inside the rectangular frame to concentrate airflow, and with the connection of the air pipes, the airflow enters the hollow rectangular frame through the air pipes. The airflow comes from bottom to top through the square tube, connecting sleeve, hollow connecting beam and U-shaped support tube. The airflow is ejected upward from the jet holes on the surface of the conical support cap, precisely performing all-area directional air cooling on the bottom of the battery module inside the U-shaped support tube. This quickly removes the heat generated by the battery during operation, effectively reducing the battery's operating temperature rise, avoiding problems such as high-temperature aging and thermal runaway, and ensuring the continuous and stable operation of the battery pack. At the same time, the air duct is integrated inside the bracket body, without occupying additional space in the power vehicle compartment, simplifying the equipment piping structure and improving the utilization rate of the compartment space.

[0032] 5. The battery bottom is stably supported by U-shaped lifting tubes in conjunction with strip-shaped and circular pads. Evenly distributed conical support caps increase the support points for the battery bottom. Wedge-shaped pushers drive the clamping plates on both sides to adaptively clamp the battery sides, achieving bidirectional fixed positioning of the battery module. Under the support and guidance of the square guide rod, the symmetrical clamping plates on both sides are more stable. With the frame composed of multiple connecting sleeves, the first connecting beam and the second connecting beam, the battery module is compacted by the U-shaped lifting tube installed on the first connecting beam. Finally, the top battery module is pressed down by the X-shaped pressing frame to prevent the battery module from shaking, ensuring safety and reliability.

[0033] VI. The rubber strips, flexible sheets, strip pads, and circular pads on the clamping plate can make flexible contact with the battery module, avoiding rigid contact, effectively buffering the impact and vibration during vehicle operation, preventing rigid collisions, wear and displacement of the battery module, protecting the battery shell and internal cell structure, and improving the safety and protection of battery pack installation.

[0046] A battery module stacked mounting bracket for a power supply vehicle, comprising:

[0047] Base 1 and X-shaped pressing bracket 2;

[0048] Support component 3 includes a rectangular frame 31 and a blower 32. The rectangular frame 31 is fixedly installed on the top of the base 1. The rectangular frame 31 is hollow. The blower 32 is fixedly installed on the inner side of the rectangular frame 31. An air pipe 33 is connected between the air outlet at the bottom of the blower 32 and the bottom of the rectangular frame 31. A square tube 34 is detachably fixedly installed on the top side of the rectangular frame 31. A locking screw 35 is threaded on the surface of the square tube 34. A round hole 36 is opened on the side of the square tube 34 away from the locking screw 35. The locking screw 35 passes through the round hole 36. An X-shaped pressing bracket 2 is detachably fixedly installed on the top of the square tube 34.

[0049] There are four hair dryers 32, and the four hair dryers 32 are evenly distributed inside the rectangular frame 31. The air pipe 33, the rectangular frame 31 and the square pipe 34 are connected to form an air supply channel.

[0050] The square tubes 34 are installed vertically. There are four square tubes 34, and the four square tubes 34 are evenly distributed on the top side of the rectangular frame 31. The locking screws 35 are evenly distributed on the surface of the square tubes 34.

[0051] The stacking mechanism 4 includes a connecting sleeve 41, a first connecting beam 42, and a second connecting beam 43. The connecting sleeve 41 is fitted onto the surface of the square tube 34. The first connecting beam 42 is fixedly installed on the surface of the connecting sleeve 41, and the second connecting beam 43 is fixedly installed on the surface of the connecting sleeve 41 and close to the first connecting beam 42. By fitting the slidable connecting sleeve 41 onto the outside of the square tube 34, and combining it with the first connecting beam 42 and the second connecting beam 43 to form a stacked support frame, multiple battery modules can be stacked and installed, achieving a neat stacked arrangement of multiple battery modules. Furthermore, the rectangular frame 31, the square tube 34, and the blower 32 adopt a modular and detachable assembly structure, simplifying the assembly and disassembly process without requiring complex auxiliary tooling. This facilitates the assembly, maintenance, and replacement of the power vehicle's battery modules, enhancing versatility. A self-locking caliper 44 is fixedly installed on the outer side of the connecting sleeve 41 near the locking screw 35. A clamping assembly 45 is installed on the surface of the second connecting beam 43. A support spring 46 is fixedly connected to the inner side of the connecting sleeve 41. A semi-circular sealing ball 47 is fixedly connected to one end of the support spring 46 near the locking screw 35. The spherical surface of the semi-circular sealing ball 47 fits against one end of the locking screw 35 inserted into the round hole 36. When the locking screw 35 is tightened, the end of the locking screw 35 squeezes the semi-circular sealing ball 47, causing the support spring 46 to undergo elastic deformation. The semi-circular sealing ball 47 moves away from the round hole 36, releasing the seal on the round hole 36. A flexible sheet 48 is fixedly connected to the inner side of the first connecting beam 42. A battery support assembly 5 is installed at the bottom of the first connecting beam 42.

[0052] When assembling the stacked mechanism 4 with the square tube 34, the connecting sleeve 41 is fitted onto the surface of the square tube 34. When the supporting spring 46 applies an elastic pushing force to the semi-circular sealing ball 47, the spherical surface of the semi-circular sealing ball 47 is made to fit against the surface of the square tube 34. As the connecting sleeve 41, the first connecting beam 42 and the second connecting beam 43 continue to slide down, the semi-circular sealing ball 47 is embedded into the interior of the circular hole 36, which can be initially positioned. This helps to fix the connecting sleeve 41 and the square tube 34 by the locking screw 35, making it less likely for the connecting sleeve 41 to shift.

[0053] The connecting sleeve 41 is fixedly installed between the locking screw 35 and the square tube 34. The end of the locking screw 35 extends into the interior of the connecting sleeve 41. The first connecting beam 42 and the second connecting beam 43 are both hollow. The structural frame composed of the connecting sleeve 41, the first connecting beam 42 and the second connecting beam 43 is evenly distributed on the surface of the square tube 34 to form a stacked battery module bracket.

[0054] Example 2, based on Example 1, see [link / reference] Figures 1 to 9 A technical solution is provided:

[0055] The first connecting beam 42 and the second connecting beam 43 are installed on the adjacent surfaces of the outer side of the connecting sleeve 41. Both the first connecting beam 42 and the second connecting beam 43 are connected to the connecting sleeve 41. The clamp head at the bottom of the self-locking clamp 44 is engaged with the hexagonal head on the outer side of the locking screw 35. The flexible sheet 48 is made of rubber. The locking screw 35 is inserted into the round hole 36, so that the end of the locking screw 35 squeezes the semi-circular sealing ball 47 and the supporting spring sheet 46 undergoes elastic deformation to achieve precise positioning and fixation. At the same time, the self-locking clamp 44 engages with the hexagonal end of the locking screw 35 to form a double anti-loosening limit structure. This solves the problem that traditional bolt structures are prone to loosening, displacement, and falling off under bumpy and vibrating conditions during the driving of the power supply vehicle. It effectively ensures the firmness of the multi-layer battery module installation in complex driving environments, avoids safety hazards caused by battery shaking and displacement, and greatly improves the reliability and service life of the equipment.

[0056] The clamping assembly 45 includes a wedge-shaped pusher 451, a first right-angle plate 452, and a second right-angle plate 453. The top end of the wedge-shaped pusher 451 is fixedly installed with the bottom of the second connecting beam 43. The bottom end of the first right-angle plate 452 is fixedly installed with the top of the second connecting beam 43. The bottom end of the second right-angle plate 453 is fixedly installed with the top of the second connecting beam 43 and close to the first right-angle plate 452. A square guide rod 454 is slidably installed on the surface of the first right-angle plate 452 and the surface of the second right-angle plate 453. A clamping plate 455 is fixedly installed at the end of the square guide rod 454. A rubber strip 456 is fixedly connected to the clamping surface of the clamping plate 455.

[0057] The bottom end of the wedge-shaped pusher 451 is inserted between the first right-angle plate 452 and the second right-angle plate 453, and the first right-angle plate 452 and the second right-angle plate 453 are installed at the same height.

[0058] The clamping plate 455 is installed on the inclined surface outside the wedge-shaped pusher 451, and the rubber strips 456 are evenly distributed on the clamping surface of the clamping plate 455.

[0059] Example 3, based on Examples 1 and 2, see below. Figures 1 to 10 A technical solution is provided:

[0060] The battery support assembly 5 includes a U-shaped support tube 51 and a strip pad 52. The top of the U-shaped support tube 51 is detachably fixed to the bottom of the first connecting beam 42. The strip pad 52 is fixedly installed at the bottom of the U-shaped support tube 51. A conical support cap 53 is connected to the bottom of the inner side of the U-shaped support tube 51. An air jet hole 54 is opened on the conical surface of the outer side of the conical support cap 53, with the air outlet of the air jet hole 54 facing upward. A circular pad 55 is fixedly connected to the top of the conical support cap 53. The rectangular frame 31, square tube 34, connecting sleeve 41, hollow connecting beam and U-shaped support tube 51 are interconnected to form an integrated built-in air supply duct. When the operator turns on the blower 32 to work, the blower is evenly distributed inside the rectangular frame. The air blower 32, connected by the air pipe 33, allows air to enter the hollow rectangular frame 31 through the air pipe 33. The airflow flows from bottom to top through the square pipe 34, connecting sleeve 41, hollow connecting beam, and U-shaped support pipe 51. The airflow is then ejected upwards from the jet holes 54 on the surface of the conical support cap 53, precisely providing directional air cooling to the bottom of the battery module inside the U-shaped support pipe 51. This quickly removes the heat generated by the battery during operation, effectively reducing the battery's operating temperature rise and preventing issues such as high-temperature aging and thermal runaway. This ensures the battery pack continues to operate stably. At the same time, the air duct is integrated inside the bracket body, eliminating the need to occupy additional space in the power vehicle compartment, simplifying the equipment piping structure, and improving the utilization rate of the compartment space.

[0061] U-shaped support tubes 51 are evenly distributed at the bottom of the first connecting beam 42, and are connected to the first connecting beam 42. Conical support caps 53 are evenly distributed at the bottom of the inner side of the U-shaped support tubes 51. The strip pads 52 and the circular pads 55 are both made of rubber. The U-shaped support tubes 51, in conjunction with the strip pads 52 and the circular pads 55, provide stable support for the bottom of the battery. The evenly distributed conical support caps 53 increase the support points for the bottom of the battery. The wedge-shaped pusher 451 drives the clamping plates 455 on both sides to adaptively clamp the sides of the battery, achieving bidirectional fixed positioning of the battery module. Under the support and guidance of the square guide rod 454, the symmetrical clamping plates 455 on both sides are more stable. With the frame composed of the multi-connecting sleeve 41, the first connecting beam 42 and the second connecting beam 43, the battery module is compacted by the U-shaped support tubes 51 installed on the first connecting beam 42. Finally, the X-shaped pressing frame 2 presses down the top battery module to prevent the battery module from shaking, ensuring safety and reliability.

[0062] The rubber strip 456, flexible sheet 48, strip pad 52 and circular pad 55 on the clamping plate 455 can make flexible contact with the battery module, avoiding rigid contact, effectively buffering the impact and vibration during vehicle driving, preventing rigid collision, wear and displacement of the battery module, protecting the battery shell and internal cell structure, and improving the safety and protection of battery pack installation.

[0063] In use, by fitting a slidable connecting sleeve 41 on the outside of the square tube 34, and combining it with the first connecting beam 42 and the second connecting beam 43 to form a stacked support frame, multiple battery modules can be stacked and installed, achieving a neat stacked arrangement of multiple battery modules. At the same time, the rectangular frame 31, the square tube 34 and the blower 32 adopt a modular and detachable assembly structure, which is convenient for installation.

[0064] When assembling the stacked mechanism 4 with the square tube 34, the connecting sleeve 41 is fitted onto the surface of the square tube 34. When the supporting spring 46 applies an elastic pushing force to the semi-circular sealing ball 47, the spherical surface of the semi-circular sealing ball 47 is made to fit against the surface of the square tube 34. As the connecting sleeve 41, the first connecting beam 42 and the second connecting beam 43 continue to slide down, the semi-circular sealing ball 47 is embedded into the inside of the circular hole 36, which can be initially positioned. This helps to fix the connecting sleeve 41 and the square tube 34 by the locking screw 35, making it less likely for the connecting sleeve 41 to shift.

[0065] The battery module is placed inside the U-shaped support tube 51. The U-shaped support tube 51, together with the strip pad 52 and the circular pad 55, provides stable support for the bottom of the battery. The evenly distributed conical support caps 53 increase the support points for the bottom of the battery. The wedge-shaped pusher 451 drives the clamping plates 455 on both sides to adaptively clamp the sides of the battery, realizing bidirectional fixed positioning of the battery module. Under the support and guidance of the square guide rod 454, the symmetrical clamping plates 455 on both sides are more stable. With the frame composed of the multi-connecting sleeve 41, the first connecting beam 42 and the second connecting beam 43, the battery module is compacted by the U-shaped support tube 51 installed on the first connecting beam 42.

[0066] Furthermore, the rubber strip 456, flexible sheet 48, strip pad 52, and circular pad 55 on the clamping plate 455 can make flexible contact with the battery module, avoiding rigid contact;

[0067] As the battery modules are added layer by layer, locking screws 35 are inserted into the round holes 36, causing the ends of the locking screws 35 to compress the semi-circular sealing balls 47 and the supporting springs 46 to deform elastically, achieving precise positioning and fixation. At the same time, self-locking calipers 44 are used to engage the hexagonal ends of the locking screws 35, forming a double anti-loosening limit structure. This solves the problem of traditional bolt structures being prone to loosening, displacement, and falling off under bumpy and vibrating conditions during the driving of the power supply vehicle. It effectively ensures the firmness of the multi-layer battery module installation in complex driving environments. Finally, the top battery module is pressed down by the X-shaped pressing bracket 2 to prevent the battery module from shaking.

[0068] The rectangular frame 31, square tube 34, connecting sleeve 41, hollow connecting beam, and U-shaped support tube 51 are interconnected to form an integrated built-in air supply duct. When the operator turns on the blower 32, the blower blows air evenly distributed inside the rectangular frame. Using the blowing force of the blower 32 and connected by the air pipe 33, the air enters the hollow rectangular frame 31 through the air pipe 33. The airflow comes from bottom to top through the square tube 34, connecting sleeve 41, hollow connecting beam, and U-shaped support tube 51. The airflow is ejected upward from the jet holes 54 on the surface of the conical support cap 53, precisely and directionally cooling the bottom of the battery module inside the U-shaped support tube 51. This quickly removes the heat generated by the battery, effectively reducing the battery's operating temperature rise and preventing problems such as high-temperature aging and thermal runaway. This ensures the battery pack continues to operate stably. At the same time, the air duct is integrated inside the bracket body, eliminating the need to occupy additional space in the power vehicle compartment, simplifying the equipment piping structure, and improving the utilization rate of the compartment space.

[0069] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
