Description

Technical Field

[0001] This invention relates to the field of battery mounting box technology, specifically to an integrated mounting box for new energy batteries. Background Technology

[0002] As the heart of new energy vehicles, the power battery is crucial to their development. However, existing integrated battery mounting boxes suffer from numerous defects in actual assembly and use, making them unsuitable for complex on-board conditions: First, the docking positioning between the top cover and the battery mounting box lacks a precise guiding structure, relying solely on threaded mounting holes, which easily leads to deviations, resulting in low assembly efficiency and insufficient stability after docking. Second, the battery pack continuously generates heat during operation. Existing boxes, with their strong airtightness, allow heat to accumulate internally, hindering rapid dissipation. Prolonged high temperatures not only cause battery performance degradation but also affect the overall lifespan of the device. Third, the shock-absorbing rubber beneath the battery pack softens under high temperatures, reducing its support performance and damping effect. Existing structures lack targeted adjustment mechanisms to compensate for the softened rubber, making it difficult to continuously and stably support the battery pack, thus affecting the device's shock absorption stability and failing to meet the demands of complex on-board conditions such as bumps and temperature fluctuations. Therefore, an integrated mounting box structure that can solve the aforementioned docking, heat dissipation, and shock absorption adaptation problems is urgently needed. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated installation box for new energy batteries to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an integrated installation box for new energy batteries, comprising a battery installation box, an upper cover plate provided at the upper end of the battery installation box, a first threaded installation hole installed around the outer side of the upper cover plate, a second threaded installation hole movably provided on the outer side of the battery installation box, a protective box installed inside the battery installation box, a battery pack installed inside the protective box, shock-absorbing rubber provided inside the protective box, the shock-absorbing rubber being fitted to the lower end of the battery pack, and a limit hole provided at the lower end of the upper cover plate; A docking and ejection mechanism is installed inside the battery mounting box and is used to assist the upper cover plate in docking and moving. A pressure regulating mechanism is installed inside the protective housing and is used to improve the stability of the device.

[0005] Preferably, the docking ejection mechanism includes a docking block, which is slidably installed in the side wall of the battery mounting box. The position of the docking block corresponds one-to-one with the position of the limiting hole, and a track groove is provided on the side wall of the battery mounting box.

[0006] Preferably, the second threaded mounting hole is slidably installed in the track groove, and an abutment block is elastically limited and installed inside the side wall of the battery mounting box. The abutment block is installed at the lower end of the mating block, and the mating block is fixedly connected to the second threaded mounting hole. The abutment block is trapezoidal in side view.

[0007] Preferably, a compression block is elastically installed on the inner wall of the battery mounting box, the compression block is located below the abutment block, and the compression block abuts against the inclined surface of the abutment block.

[0008] Preferably, the docking ejection mechanism further includes a movable frame, which is slidably mounted on the side wall of the protective box. An air blowing head is rotatably mounted inside the movable frame via a torsion spring. Two sets of movable frames are symmetrically arranged in a horizontal straight line at the front and rear of the protective box.

[0009] Preferably, an electric push rod is installed inside the battery mounting box, and a movable block is connected to the top end of the electric push rod. The movable block is an isosceles trapezoid when viewed from the front, and the inclined surfaces on both sides of the movable block abut against the moving frame. The squeezing block is located on the moving trajectory of the blowing head.

[0010] Preferably, the pressure regulating mechanism includes a squeezing plate, which is installed inside the protective box and located at the lower end of the shock-absorbing rubber. A sliding track is installed inside the protective box.

[0011] Preferably, a pressure spring is installed inside the sliding track, and a sliding block is connected to the other end of the pressure spring. A connecting rod is rotatably installed on the sliding block, and the connecting rod is rotatably connected to the extrusion plate.

[0012] Preferably, the lower end of the connecting rod is rotatably mounted inside the protective box, and a shock-absorbing damping device is connected between the extrusion plate and the inner wall of the protective box.

[0013] Preferably, the pressure regulating mechanism further includes an oil cylinder one, which is symmetrically installed at both ends of the sliding track. The piston rod of the oil cylinder one is connected to the sliding block. The oil cylinder one is connected to an oil cylinder two through a fluid delivery hose. The oil cylinder two is fixedly installed inside the battery mounting box. The piston rod of the oil cylinder two is located on the movement trajectory of the moving frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. Facilitates quick and precise docking of the upper cover plate: By setting up a docking ejection mechanism, the docking block and the lower limit hole of the upper cover plate are matched one-to-one. Combined with the linkage of the abutment block and the extrusion block, the upper cover plate is quickly positioned, effectively avoiding alignment deviations during docking and enabling rapid installation of the device. As the temperature rises, the internal temperature sensor detects the temperature increase and pushes the moving frame on the protective box via the electric push rod and the movable block. During the sliding process, the air blowing head abuts against the extrusion block, and the air blowing head is offset under the action of the abutment block. After a certain angle, the limit switch begins to push the extrusion block to move, so that the extrusion block squeezes the abutment block. The abutment block then drives the docking block to move upward, moving the top cover plate along the sliding groove and opening a certain gap for heat dissipation. At the same time, the deflected air blowers are arranged at an angle, and the airflows converge and collide, forming a swirling and turbulent vortex field inside the box, forcibly disturbing the air inside the box. Hot air is not easy to stay at the top and corners, and the heat exchange efficiency is greatly improved. This achieves the synergy of heat dissipation and docking functions, effectively reducing the battery pack operating temperature and improving the battery's charging and discharging performance and service life. 2. Through the coordinated operation of the pressure regulating mechanism, damping rubber, and damping, the device's vibration damping performance and operational stability are significantly improved, effectively protecting the battery pack from vibration and impact damage. The extrusion plate, attached to the lower end of the damping rubber, transmits the weight and vibration force of the battery pack to the connecting rod and sliding block. The pressure spring adaptively adjusts the buffering force through elastic deformation to cope with vibration and impact under different operating conditions. The damping further weakens vibration transmission, preventing the battery pack from shaking violently. At high temperatures, the modulus of the damping pads and spring damping components decreases and softens, weakening the support rigidity. When the vehicle body vibrates, the box shakes more, and the stability deteriorates. Through the transmission of hydraulic cylinders one and two, at high temperatures, the pressure spring is squeezed by the sliding block on the sliding rail, increasing the support force of the extrusion plate on the damping rubber. This achieves coordinated operation of the pressure regulating and docking ejection mechanism, further improving the overall stability of the device. Attached Figure Description

[0017] Please see Figures 1-9 The present invention provides a technical solution: an integrated installation box for new energy batteries, including a battery installation box 1, an upper cover plate 2 provided at the upper end of the battery installation box 1, a threaded installation hole 3 circumferentially installed on the outer side of the upper cover plate 2, a threaded installation hole 4 movably provided on the outer side of the battery installation box 1, a protective box 5 installed inside the battery installation box 1, a battery pack 6 provided inside the protective box 5, shock-absorbing rubber 7 provided inside the protective box 5, the shock-absorbing rubber 7 being fitted to the lower end of the battery pack 6, and a limit hole 8 provided at the lower end of the upper cover plate 2; The docking and ejection mechanism is located inside the battery mounting box 1 and is used to assist the upper cover plate 2 in docking and moving. The pressure regulating mechanism is located inside the protective box 5 and is used to improve the stability of the device.

[0018] As one embodiment of the present invention, the docking ejection mechanism includes a docking block 9, which is slidably installed in the side wall of the battery mounting box 1. The position of the docking block 9 corresponds one-to-one with the position of the limiting hole 8. A track groove 10 is provided on the side wall of the battery mounting box 1.

[0019] In one embodiment of the present invention, the threaded mounting hole 4 is slidably installed in the track groove 10, and the battery mounting box 1 is elastically limited and installed inside the side wall. The abutment block 11 is installed at the lower end of the docking block 9, and the docking block 9 is fixedly connected to the threaded mounting hole 4. The abutment block 11 is trapezoidal in side view.

[0020] In one embodiment of the present invention, a compression block 12 is elastically limited and installed on the inner wall of the battery mounting box 1. The compression block 12 is located below the abutment block 11 and abuts against the inclined surface of the abutment block 11.

[0021] As one embodiment of the present invention, the docking ejection mechanism further includes a movable frame 13, which is slidably mounted on the side wall of the protective box 5. An air blowing head 14 is rotatably mounted inside the movable frame 13 by a torsion spring. Two sets of movable frames 13 are symmetrically arranged in a horizontal straight line at the front and rear of the protective box 5.

[0022] In one embodiment of the present invention, an electric push rod 15 is installed inside the battery mounting box 1. The top end of the electric push rod 15 is connected to a movable block 16. The movable block 16 is an isosceles trapezoid when viewed from the front. The inclined surfaces on both sides of the movable block 16 abut against the movable frame 13. The squeezing block 12 is located on the moving trajectory of the blowing head 14.

[0023] During assembly, the upper cover plate 2 is aligned with the upper end of the battery mounting box 1, ensuring that the limiting hole 8 precisely corresponds to the docking block 9. The docking block 9, supported by the elastic support of the abutment block 11, is embedded in the limiting hole 8 and secured by bolts through threaded mounting holes 3 and 4. When the battery pack 6 heats up, the temperature sensor triggers the electric push rod 15 to move the movable block 16, causing the movable frame 13 to slide along the protective box 5. After the air blowing head 14 comes into contact with the extrusion block 12, it deflects, pushing the extrusion block 12 to press against the abutment block 11, causing the docking block 9 to move the upper cover plate 2 upward, forming a heat dissipation gap. The tilted air blowing head 14 blows out an airflow that forms a vortex, quickly dissipating heat through the gap, achieving a synergistic effect of docking and heat dissipation.

[0024] In one embodiment of the present invention, the pressure regulating mechanism includes a pressure plate 17, which is installed inside the protective box 5. The pressure plate 17 is located at the lower end of the shock-absorbing rubber 7, and a sliding rail 18 is installed inside the protective box 5.

[0025] In one embodiment of the present invention, a pressure spring 19 is installed inside the sliding track 18, and a sliding block 20 is connected to the other end of the pressure spring 19. A connecting rod 21 is rotatably installed on the sliding block 20, and the connecting rod 21 is rotatably connected to the extrusion plate 17.

[0026] In one embodiment of the present invention, the lower end of the connecting rod 21 is rotatably installed inside the protective box 5, and a shock-absorbing damping 22 is connected between the extrusion plate 17 and the inner wall of the protective box 5.

[0027] In one embodiment of the present invention, the pressure regulating mechanism further includes an oil cylinder 23, which is symmetrically installed at both ends of the sliding track 18. The piston rod 24 of the oil cylinder 23 is connected to the sliding block 20. The oil cylinder 23 is connected to an oil cylinder 25 through a fluid delivery hose. The oil cylinder 25 is fixedly installed inside the battery mounting box 1. The piston rod 26 on the oil cylinder 25 is located on the movement trajectory of the moving frame 13.

[0028] The battery pack 6 is placed inside the protective box 5, with the shock-absorbing rubber 7 attached to its lower end for basic vibration damping. When the device is subjected to bumps, the vibration force is transmitted through the shock-absorbing rubber 7 to the compression plate 17, which pushes the connecting rod 21 to drive the sliding block 20 to slide along the sliding track 18. The pressure spring 19 deforms to buffer the vibration, and the shock-absorbing damper 22 weakens the transmission of vibration. At high temperatures, the shock-absorbing rubber 7 softens, and the moving frame 13 pushes the piston rod 26, causing the oil in the oil cylinder 25 to flow into the oil cylinder 23. The piston rod 24 pushes the sliding block 20 to compress the pressure spring 19, which increases the support force on the shock-absorbing rubber 7 through the compression plate 17, compensating for insufficient rigidity and improving stability.

[0029] Working principle: Align the upper cover plate 2 with the upper end of the battery mounting box 1, so that the limiting hole 8 at the lower end of the upper cover plate 2 corresponds one-to-one with the docking block 9 in the side wall of the battery mounting box 1. The docking block 9 is embedded in the limiting hole 8 under the elastic support of the abutment block 11, so as to achieve precise positioning of the upper cover plate 2. Then, the upper cover plate 2 and the battery mounting box 1 are connected by bolts through the threaded mounting hole 1 3 and the threaded mounting hole 2 4 that is slidably installed in the track groove 10. When the battery pack 6 generates heat during operation and the temperature rises, the internal temperature sensor detects the temperature change and controls the electric push rod 15 to start. The top end of the electric push rod 15 pushes the movable block 16 to move. Since the movable block 16 is an isosceles trapezoid when viewed from the front, its two inclined surfaces abut against the movable frame 13 symmetrically arranged on the side wall of the protective box 5, thereby pushing the two sets of movable frames 13 to slide horizontally along the side wall of the protective box 5. During the sliding process of the moving frame 13, the air blowing head 14, which is installed inside by a torsion spring, comes into contact with the squeezing block 12. Under the contact force, the air blowing head 14 deflects at a certain angle and is limited. The air blowing head 14, which continues to move with the moving frame 13, pushes the squeezing block 12 to move. The squeezing block 12 comes into contact with the inclined surface of the contact block 11, which in turn squeezes the contact block 11 and drives the docking block 9 to move upward. The docking block 9 pushes the upper cover plate 2 to move upward along the track groove 10, so that a heat dissipation gap is formed between the upper cover plate 2 and the battery mounting box 1. The two air blowing heads 14 after rotation are arranged at an inclined angle. After starting, the airflow converges and collides, forming a swirling and turbulent vortex field between the battery mounting box 1 and the protective box 5, which forcibly disturbs the air inside the box and prevents hot air from accumulating at the top and corners. With the heat dissipation gap opened by the upper cover plate 2, the heat inside the box is quickly discharged, achieving the synergy of heat dissipation and docking and ejection functions, and effectively reducing the working temperature of the battery pack 6. The battery pack 6 is placed inside the protective box 5. The shock-absorbing rubber 7 inside the protective box 5 is attached to the lower end of the battery pack 6, which plays a basic role in shock absorption and buffering. When the device is subjected to external bumps and vibrations, the vibration force of the battery pack 6 is transmitted to the shock-absorbing rubber 7. The shock-absorbing rubber 7 undergoes elastic deformation for initial buffering. The remaining vibration force is transmitted to the connecting rod 21 through the extrusion plate 17, which in turn pushes the sliding block 20 to slide in the sliding track 18. The pressure spring 19 inside the sliding track 18 undergoes elastic deformation to buffer the vibration force. The shock-absorbing damper 22 simultaneously weakens the vibration transmission, preventing the battery pack 6 from shaking violently and protecting the battery pack 6 from vibration impact damage. When the temperature rises, the modulus of the elastic components such as the damping rubber 7 decreases and softens, weakening the support rigidity. The sliding frame 13, which slides to both sides, pushes the piston rod 26 to transfer the oil inside the oil cylinder 25 through the infusion hose to the oil cylinder 23. Then, the piston rod 24 pushes the sliding block 20 along the sliding track 18 to squeeze the pressure spring 19, pushing the extrusion plate 17 to move upward and increase its compression on the softened damping rubber 7. This compensates for the insufficient support rigidity of the elastic components at high temperatures, realizes the coordinated work of pressure regulation and docking ejection mechanism, and further improves the overall stability of the device.
