Description

Technical Field

[0001] The invention relates to electrical equipment, in particular to a high-voltage control box. Background Art

[0002] New energy power batteries are one of the core components of electric vehicles, and the high-voltage control unit (BDU), as an important component of the new energy battery pack, coordinates the function conversion and energy distribution of high-voltage accessories such as the drive motor control system, battery management system, charging management system, DC / DC, electric air conditioning, resistance power steering, and braking system, as well as realizing safety functions such as fast power-off protection and leakage protection for short-circuit overload. With the growth of electric vehicle sales and the improvement of vehicle quality requirements, the market demand for reliable, integrated, lightweight, and cost-effective BDU products continues to increase. For example, the utility model patent with announcement number CN208881735U discloses a similar high-voltage control box.

[0003] The high-voltage control box mentioned above is usually cooled to improve working stability. Fig.15 As shown, the traditional cooling method is to sequentially set an insulating film 2, a heat dissipation pad 3 and a water-cooled plate 4 at the bottom of the high-voltage control box body 1. After the water inlet 5 and the water outlet 6 of the water-cooled plate 4 are connected to an external water source and a water pump through a water pipe, water circulation can be performed to achieve heat exchange, thereby reducing the temperature of the high-voltage control box. The traditional water-cooled plate 4 is troublesome and has low installation efficiency because the water inlet 5 and the water outlet 6 need to be operated separately when disassembling and installing the water pipe. Therefore, a docking structure is specially designed. When disassembling and installing the water pipe on the water-cooled plate 4, the connection and disconnection between the water inlet 5, the water outlet 6 and the external water pipe can be completed at the same time, thereby improving operating efficiency and convenience. The specific scheme of the docking structure is as follows. Fig.15 and Fig.16 As shown, a water inlet nozzle 5 and a water outlet nozzle 6 are vertically arranged on one side of the water cooling plate 4 close to the high-pressure control box body 1. The water inlet nozzle 5 and the water outlet nozzle 6 are adjacent to each other and are connected to each other with a plug head 7. The bottom of the plug head 7 is penetrated by a water inlet hole 8 and a water outlet hole 9 for sealing and plugging the water inlet nozzle 5 and the water outlet nozzle 6 respectively. The upper ends of the water inlet hole 8 and the water outlet hole 9 are sealedly connected with a water inlet pipe 10 and a water outlet pipe 11.

[0004] Although the above-mentioned docking structure can effectively improve the operational efficiency and convenience when disassembling and installing water pipes of the water cooling plate, double hole calibration is required during operation, which has a certain operating threshold. After the installation is completed, the plug head may become loose due to external shaking when the high-pressure control box is working, thereby causing the risk of leakage. Therefore, it still needs to be improved. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a high-pressure control box, which can improve the calibration efficiency and convenience of the double hole positions of the plug and unplug head when installing the water pipe on the water cooling plate, and prevent the plug and unplug head from loosening, thereby ensuring the sealing.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0007] A high-pressure control box comprises a high-pressure control box body and a water-cooling plate arranged on the high-pressure control box body, a water inlet nozzle and a water outlet nozzle are arranged adjacent to each other on one side of the water-cooling plate close to the high-pressure control box body, a plug-in head is connected to the water inlet nozzle and the water outlet nozzle, a positioning column is arranged on the water-cooling plate, a positioning hole for the positioning column to pass through is penetrated at the bottom of the plug-in head, an upper end of the positioning column exceeds the upper surface of the plug-in head and telescopic grooves are arranged on both sides of the exceeding part, a telescopic buckle is arranged in the telescopic groove for lateral sliding, and a lower port for the positioning hole is arranged on the upper surface of the telescopic buckle to squeeze to drive the extension The guide slope for the shrink buckle to retract inward; the positioning column is provided with an elastic driving mechanism for driving the telescopic buckle to pop outward to prevent the plug-in head from detaching from the positioning column, an unlocking mechanism for driving the telescopic buckle to overcome the elastic force of the elastic driving mechanism and retract into the telescopic slot in response to an external trigger, and a linkage mechanism following the action of the unlocking mechanism to drive the plug-in head to move up and limit the telescopic buckle from extending out of the telescopic slot, the unlocking mechanism includes an inclined guiding surface opened on the upper edge of the telescopic slot to cooperate with the guiding slope, and a lifting component for the two telescopic buckles to slide laterally and can drive both to move up in response to an external trigger.

[0008] By adopting the above scheme, when the plug-in head is docked with the water inlet and outlet on the water cooling plate, the plug-in head and the water inlet and outlet can be quickly positioned with the help of the plug-in cooperation between the positioning column and the positioning hole, thereby improving the operating efficiency and accuracy. The telescopic buckle can extend out of the telescopic groove under the drive of the elastic driving mechanism to complete the longitudinal locking of the plug-in head, thereby preventing the plug-in head from loosening. The unlocking mechanism can drive the telescopic buckle to overcome the elastic force of the elastic driving mechanism and shrink into the telescopic groove to release the longitudinal locking of the plug-in head, thereby creating conditions for removing the plug-in head. After the unlocking mechanism releases the longitudinal locking of the plug-in head, the linkage mechanism can drive the plug-in head to move up a certain distance to limit the telescopic buckle from popping out, thereby facilitating the operator to switch his hand to the plug-in head, and then facilitating the operator to remove the plug-in head. During the installation of the plug head, when the positioning hole at the bottom of the plug head is docked with the upper end of the positioning column, and the edge of the positioning hole is pressed against the guiding inclined surface on the telescopic buckle, it can overcome the elastic force of the elastic driving mechanism to drive the telescopic buckle to retract inward, so that the plug head can smoothly dock with the water inlet and outlet. When the water inlet and outlet holes on the plug head are completely docked with the water inlet and outlet, the positioning hole moves to the bottom of the telescopic buckle, and the telescopic buckle pops up again after losing the barrier to lock the plug head longitudinally. In this way, the operator can complete the installation and locking of the plug head with one hand, further improving the operating efficiency and convenience. When the lifting assembly drives the two telescopic buckles to move upward under the action of external force, the inclined guiding surface on the telescopic groove can squeeze the guiding inclined surface on the telescopic buckle to drive the two telescopic buckles to retract inward, thereby releasing the longitudinal locking of the plug head, and making it convenient for the operator to remove the plug head.

[0009] Preferably, the lifting assembly includes a sliding channel opened in the positioning column along the length direction of the positioning column itself and connected to the two telescopic grooves, and a lifting platform slidably arranged in the sliding channel, the telescopic buckle is laterally slidably arranged on the upper surface of the lifting platform, the elastic driving mechanism is installed on the lifting platform, and the lifting platform is provided with a driving member that responds to an external trigger to drive the lifting platform to rise.

[0010] By adopting the above solution, the cooperation between the lifting platform and the sliding channel can improve the operating efficiency and stability of the lifting assembly.

[0011] Preferably, guide blocks are provided on both sides of the lifting platform, and guide grooves for sliding connection of the guide blocks are provided on the inner side walls of the sliding channel along the length direction thereof.

[0012] By adopting the above solution, the sliding cooperation between the guide block and the guide groove can improve the stability and smoothness of the longitudinal sliding of the lifting platform, and further improve the operating accuracy and efficiency.

[0013] Preferably, the linkage mechanism includes a connecting rod connected to the bottom of the guide block and slidably engaged in the guide groove, and a push plate arranged at the lower end of the connecting rod and abutting against the bottom of the plug-in head; when the lifting platform rises along with the driving member to a state where the telescopic buckle completely enters the telescopic groove, the lifting platform can drive the plug-in head to move up through the connecting rod and the push plate, so that the side wall of the positioning hole blocks the opening of the telescopic groove, thereby preventing the telescopic buckle from popping out.

[0014] With the above solution, during the process of removing the plug head, after the driving member drives the telescopic buckle on the lifting platform to retract, the plug head can move up a certain distance with the lifting platform to block the opening of the telescopic slot through the side wall of the positioning hole. At this time, even if the operator releases the driving member, the telescopic buckle will not pop out, so that the operator can switch his hand to the plug head, so that the plug head can be completely removed from the positioning column, thereby improving the operating efficiency and convenience.

[0015] Preferably, when the plug-in head is fully docked with the water inlet and the water outlet, a gap is maintained between the upper surface of the plug-in head and the lower surface of the telescopic buckle, a locking block is provided on the upper surface of the plug-in head corresponding to the position of the telescopic buckle, and a locking groove is provided on the lower surface of the telescopic buckle for the locking block to be inserted to prevent the telescopic buckle from contracting.

[0016] By adopting the above scheme, when the plug head is actively lifted upward, the locking block on the plug head can be inserted into the locking groove at the bottom of the telescopic buckle to prevent the telescopic buckle from contracting, so that the upward pulling drive member becomes the only way to release the longitudinal lock of the plug head, thereby effectively preventing the plug head from detaching from the positioning column by itself, and further improving the installation stability of the plug head.

[0017] Preferably, a cover for the driving member to vertically slide through is provided at the upper end of the sliding channel, and a first positioning member and a second positioning member are provided on the driving member, which are respectively located on the outer side and the inner side of the cover;

[0018] When the driving member drives the lifting platform to rise until the telescopic buckle completely enters the telescopic slot, the second positioning member abuts against the lower surface of the cover;

[0019] When the driving member is lowered along with the lifting platform to a state where the telescopic buckle is fully ejected, the first positioning member abuts against the upper surface of the cover.

[0020] By adopting the above solution, the first positioning member and the second positioning member can limit the extreme positions of the driving member and the lifting platform, thereby preventing structural damage caused by excessive operation by personnel.

[0021] Preferably, the elastic driving mechanism includes a plurality of guide springs arranged laterally above the lifting platform, and the ends of the guide springs for providing elastic supporting force are connected to the inner side of the telescopic buckle; a guide rail is arranged on the upper surface of the lifting platform along the moving direction of the telescopic buckle, and a guide groove is provided at the bottom of the telescopic buckle for slidingly engaging with the guide rail.

[0022] With the above solution, the guide spring can not only provide a stable and lasting elastic support force for the telescopic buckle, but also play a guiding role, thereby ensuring the smoothness of the telescopic buckle during movement. The cooperation between the guide slot and the guide rail can further improve the movement stability of the telescopic buckle, thereby further improving the operating efficiency and convenience.

[0023] Preferably, the bottom of the plug head is penetrated by a water inlet hole and a water outlet hole for sealing and plugging the water inlet nozzle and the water outlet nozzle respectively.

[0024] Preferably, the inner wall of the water inlet hole is provided with a sealing ring 1, the inner side of which is sealed with the outer wall of the water inlet nozzle; the inner wall of the water outlet hole is provided with a sealing ring 2, the inner side of which is sealed with the outer wall of the water outlet nozzle.

[0025] With the above solution, the sealing ring can not only increase the sealing between the water inlet and the water inlet nozzle and the water outlet and the water outlet nozzle, but also provide strong anti-slip performance. When the plug head moves up a certain distance under the action of the push plate, it can use the anti-slip ability of the sealing ring to hover at the current position to prevent the plug head from sliding down, thereby preventing the telescopic buckle from popping out automatically, and making the removal of the plug head smoother.

[0026] The present invention has significant technical effects due to the adoption of the above technical solutions: when the plug-in head is docked with the water inlet and outlet on the water cooling plate, the plug-in head and the water inlet and outlet can be quickly positioned with the help of the plug-in cooperation between the positioning column and the positioning hole, thereby improving the operation efficiency and accuracy. The telescopic buckle can extend out of the telescopic groove under the drive of the elastic driving mechanism to complete the longitudinal locking of the plug-in head, thereby preventing the plug-in head from loosening. The unlocking mechanism can drive the telescopic buckle to overcome the elastic force of the elastic driving mechanism and shrink into the telescopic groove to release the longitudinal locking of the plug-in head, thereby creating conditions for removing the plug-in head. The linkage mechanism can drive the plug-in head to move up a certain distance after the unlocking mechanism releases the longitudinal locking of the plug-in head, so as to limit the telescopic buckle from popping out, thereby facilitating the operator to switch his hand to the plug-in head, and then facilitating the operator to remove the plug-in head. During the installation of the plug head, when the positioning hole at the bottom of the plug head is docked with the upper end of the positioning column, and the edge of the positioning hole is pressed against the guiding inclined surface on the telescopic buckle, it can overcome the elastic force of the elastic driving mechanism to drive the telescopic buckle to retract inward, so that the plug head can smoothly dock with the water inlet and outlet. When the water inlet and outlet holes on the plug head are completely docked with the water inlet and outlet, the positioning hole moves to the bottom of the telescopic buckle, and the telescopic buckle pops up again after losing the barrier to lock the plug head longitudinally. In this way, the operator can complete the installation and locking of the plug head with one hand, further improving the operating efficiency and convenience. When the lifting assembly drives the two telescopic buckles to move upward under the action of external force, the inclined guiding surface on the telescopic groove can squeeze the guiding inclined surface on the telescopic buckle to drive the two telescopic buckles to retract inward, thereby releasing the longitudinal locking of the plug head, and making it convenient for the operator to remove the plug head.

[0044] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0045] like Figures 1 to 14 As shown, a high-voltage control box disclosed in this embodiment includes a high-voltage control box body 1, and an insulating film 2, a heat dissipation pad 3 and a water-cooling plate 4 are sequentially arranged at the bottom of the high-voltage control box body 1, and a water inlet 5 and a water outlet 6 are vertically arranged on the side of the water-cooling plate 4 close to the high-voltage control box body 1. The water inlet 5 and the water outlet 6 are arranged adjacent to each other and are commonly connected with a plug head 7, and the bottom of the plug head 7 is penetrated by a water inlet hole 8 and a water outlet hole 9 for sealing and plugging the water inlet 5 and the water outlet 6 respectively. A sealing ring 33 made of rubber is fixedly arranged on the inner side wall of the water inlet hole 8, and a plurality of sealing rings 33 are provided, which are arranged along the length direction of the water inlet hole 8, and the inner side of the sealing ring 33 is sealed with the outer side wall of the water inlet 5, thereby effectively improving the sealing between the water inlet hole 8 and the water inlet 5. Correspondingly, a rubber sealing ring 34 is fixedly provided on the inner wall of the water outlet hole 9. There are also multiple sealing rings 34, which are arranged along the length direction of the water outlet hole 9, and the inner side of the sealing ring 34 is sealed with the outer wall of the water outlet nozzle 6, thereby effectively improving the sealing between the water outlet hole 9 and the water outlet nozzle 6.

[0046] In order to facilitate the external water pump and water source, the upper ends of the water inlet hole 8 and the water outlet hole 9 are respectively plugged with a water inlet pipe 10 and a water outlet pipe 11, and the outer walls of the water inlet pipe 10 and the water outlet pipe 11 are respectively sealed and connected to the inner walls of the water inlet hole 8 and the water outlet hole 9 by waterproof glue. A square positioning column 12 is vertically arranged on the side of the water cooling plate 4 close to the high-pressure control box body 1 and between the water inlet nozzle 5 and the water outlet nozzle 6. A square positioning hole 14 for the positioning column 12 to penetrate is penetrated at the bottom of the plug head 7. The plug-in cooperation between the positioning column 12 and the positioning hole 14 can help the operator to calibrate the hole position, thereby improving the installation efficiency and convenience of the plug head 7.

[0047] In order to improve the stability of the plug head 7 after installation, the upper end of the positioning column 12 exceeds the upper surface of the plug head 7 and telescopic grooves 16 are provided on both sides of the protruding part. A telescopic buckle 13 is provided in the telescopic groove 16 for horizontal sliding. The positioning column 12 is provided with an elastic driving mechanism for driving the telescopic buckle 13 to pop outward to prevent the plug head 7 from detaching from the positioning column 12. The upper surface of the telescopic buckle 13 is provided with a guiding inclined surface 15 for the lower end of the positioning hole 14 to squeeze to drive the telescopic buckle 13 to retract inward, thereby improving the installation efficiency and convenience of the plug head 7.

[0048] In order to release the longitudinal locking of the plug head 7, a sliding channel 17 connected to the two telescopic grooves 16 is provided in the positioning column 12 along its length direction, a lifting platform 18 is provided in the sliding channel 17 along its length direction, the telescopic buckle 13 is provided on the upper surface of the lifting platform 18 for transverse sliding, and the elastic driving mechanism is installed on the lifting platform 18. Specifically, the elastic driving mechanism includes a plurality of guide springs 30 transversely fixed above the lifting platform 18, and the ends of the guide springs 30 for providing elastic support force are fixedly connected to the inner side of the telescopic buckle 13. The inner side wall of each telescopic buckle 13 is provided with an avoidance hole 36 for the tail end 35 of the opposite guide spring 30 to pass through, thereby preventing the telescopic buckle 13 from being interfered with during the contraction process. In addition, a trapezoidal guide rail 31 is provided on the upper surface of the lifting platform 18 along the movable direction of the telescopic buckle 13, and a trapezoidal guide slot 32 is provided at the bottom of the telescopic buckle 13 for sliding and clamping on the guide rail 31, thereby improving the stability and smoothness of the telescopic buckle 13 when it is extended and retracted. The upper edge of the telescopic slot 16 is provided with an inclined guide surface 19 matched with the guiding slope 15 . The lifting platform 18 is provided with a driving member 20 . The driving member 20 is rod-shaped and vertically fixed to the upper surface of the lifting platform 18 and exceeds the upper end surface of the positioning column 12 .

[0049] In this embodiment, when the driving member 20 drives the lifting platform 18 to rise in response to an external trigger, the inclined guide surface 19 on the telescopic groove 16 can longitudinally squeeze the corresponding guiding inclined surface 15 on the telescopic buckle 13, so that the telescopic buckle 13 can overcome the elastic supporting force of the elastic driving mechanism and contract, thereby releasing the longitudinal locking of the plug head 7.

[0050] In order to improve the stability and smoothness of the lifting platform 18 during movement, guide blocks 21 are provided on both sides of the lifting platform 18 , and the inner side wall of the sliding channel 17 is provided with a guide groove 22 along its length direction for the guide block 21 to slide and connect.

[0051] In order to improve the efficiency and convenience of disassembling the plug head 7, the guide block 21 extends downward with a connecting rod 23 that is slidably engaged in the guide groove 22, and the lower end of the connecting rod 23 is provided with a push plate 24 that abuts against the bottom of the plug head 7. In this embodiment, when the lifting platform 18 rises with the driving member 20 to a state where the telescopic buckle 13 completely enters the telescopic groove 16, the lifting platform 18 can drive the plug head 7 to move up through the connecting rod 23 and the push plate 24, so that the side wall of the positioning hole 14 blocks the opening of the telescopic groove 16, thereby preventing the telescopic buckle 13 from popping out, and then facilitating the operator to remove the plug head 7 from the positioning column 12 with one hand. Among them, the guide groove 22 is connected to the outer side wall of the positioning column 12, thereby ensuring that the push plate 24 can be connected with the connecting rod 23 and rise and fall synchronously.

[0052] In order to prevent the plug head 7 from detaching from the positioning column 12 by itself, when the plug head 7 is completely connected to the water inlet nozzle 5 and the water outlet nozzle 6, a gap is maintained between the upper surface of the plug head 7 and the lower surface of the telescopic buckle 13, and a locking block 25 is provided on the upper surface of the plug head 7 corresponding to the position of the telescopic buckle 13, and a locking groove 26 is provided on the lower surface of the telescopic buckle 13 for the locking block 25 to be inserted into to prevent the telescopic buckle 13 from shrinking.

[0053] In order to prevent structural damage caused by excessive operation by personnel, a cover 27 for the driver 20 to slide vertically is provided at the upper end of the sliding channel 17, and a first positioning member 28 and a second positioning member 29 are provided on the driver 20, which are respectively located on the outer side and the inner side of the cover 27. The first positioning member 28 and the second positioning member 29 are preferably convex rings arranged around the outer peripheral surface of the driver 20. In this embodiment, when the driver 20 drives the lifting platform 18 to rise to the state where the telescopic buckle 13 completely enters the telescopic groove 16, the second positioning member 29 abuts against the lower surface of the cover 27; correspondingly, when the driver 20 descends with the lifting platform 18 to the state where the telescopic buckle 13 is completely ejected, the first positioning member 28 abuts against the upper surface of the cover 27. A gripping member 37 is provided at the upper end of the driver 20, so as to improve the operating convenience of the driver 20. The maximum lateral dimension of the gripping member 37 is smaller than the upper end surface dimension of the positioning column 12, so as to facilitate the docking of the positioning column 12 with the positioning hole 14.

[0054] The specific usage process is as follows:

[0055] When installing external water pipes on the water inlet 5 and the water outlet 6 of the water cooling plate 4, it is only necessary to dock the plug head 7 equipped with the water inlet pipe 10 and the water outlet pipe 11 on the water inlet 5 and the water outlet 6. During the docking process, the positioning column 12 on the water cooling plate 4 and the positioning hole 14 on the plug head 7 are first pre-positioned. During the positioning process, the water inlet hole 8 and the water outlet hole 9 on the plug head 7 can be docked with the water inlet 5 and the water outlet 6 on the water cooling plate 4 respectively. At this time, the lower port of the positioning hole 14 moves down with the plug head 7 and squeezes the guiding inclined surfaces 15 on the two telescopic buckles 13 to drive the telescopic buckles 13 to overcome the elastic force of the guide spring 30 and shrink, so that the plug head 7 can be pressed down smoothly. When the plug head 7 is fully pressed, it can press the push plates 24 on both sides of the positioning column 12 to the bottom, thereby pulling the lifting platform 18 in the positioning column 12 down to the position where the telescopic buckle 13 is directly opposite to the telescopic groove 16 through the connecting rod 23. At this time, the telescopic buckle 13 can be extended under the elastic force of the guide spring 30, thereby completing the longitudinal locking of the plug head 7. In this state, the water inlet nozzle 5 and the water outlet nozzle 6 are completely inserted into the water inlet hole 8 and the water outlet hole 9, and the sealing is completed by the sealing ring 1 33 and the sealing ring 2 34, thereby achieving the docking of the water inlet pipe 10 and the water inlet nozzle 5, and the water outlet pipe 11 and the water outlet nozzle 6.

[0056] When removing the plug head 7, first use the gripping member 37 to pull up the driving member 20 to drive the lifting platform 18 and the telescopic buckle 13 to move upward. Under the mutual compression of the inclined guide surface 19 and the guiding inclined surface 15, the telescopic buckle 13 can overcome the elastic force of the guide spring 30 and shrink. At the same time, the lifting platform 18 drives the push plate 24 to move upward through the connecting rod 23, so that the plug head 7 is lifted up a distance with the help of the push plate 24. When the lifting platform 18 rises to the state where the telescopic buckle 13 completely enters the telescopic groove 16, the plug head 7 can rise to the position of the telescopic groove 16, so as to block the opening of the telescopic groove 16 through the inner side wall of the positioning hole 14, thereby preventing the telescopic buckle 13 from popping out. At this time, under the anti-slip effect of the sealing ring 1 33 and the sealing ring 2 34, the plug head 7 can hover at the current position, so that the telescopic buckle 13 remains in the contracted state. In this state, the operator can switch his hands to the plug head 7 to remove the plug head 7 from the positioning column 12, thereby completing the separation of the water inlet pipe 10 and the water inlet nozzle 5 and the water outlet pipe 11 and the water outlet nozzle 6.

[0057] If the plug head 7 is forcibly unplugged without operating the driving member 20, the locking block 25 above the plug head 7 will be engaged with the locking groove 26 on the corresponding telescopic buckle 13 during the rising process of the plug head 7, thereby preventing the telescopic buckle 13 from shrinking inwards, thereby preventing accidental touch.
