Description

Technical Field

[0001] This utility model relates to the field of drive assembly technology, and in particular to an integrated heat dissipation structure for a new energy drive assembly. Background Technology

[0002] With the adjustment of the new energy structure, the market share of new energy vehicles is getting larger and larger. New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source and transmit this power to the drive motor to drive the gearbox. The vehicle's drive system includes the motor and controller, which are usually installed inside the housing. When the vehicle's drive system is operating, it will generate a lot of heat, so a fan is needed to cool it down.

[0003] Currently, there are still some shortcomings in the heat dissipation structure of the drive assembly. Although the existing heat dissipation structure can dissipate heat from the drive assembly, the fan of the heat dissipation mechanism is installed inside the housing with bolts and is integrated with the housing. Over time, the fan will be damaged, making it inconvenient for staff to disassemble and install it, thereby reducing the efficiency of heat dissipation structure maintenance. To address this, we propose an integrated heat dissipation structure for new energy drive assemblies. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated heat dissipation structure for a new energy drive assembly. Its advantages include convenient fan installation and removal, improving maintenance efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated heat dissipation structure for a new energy drive assembly includes a housing and a connecting box. Two connecting components are respectively connected to the top and bottom of the inner wall of the housing. Placement slots are provided on both sides of the housing, and locking mechanisms are provided inside each of the placement slots, extending to the outside of the placement slots. An installation component is provided on the front of the housing, and the installation component is movably connected to four connecting components. The two locking mechanisms are movably connected to the installation component on the installation component. Two heat dissipation components are provided on the installation component. A horizontal groove is provided at the bottom of the inner wall of the connecting box. A first buffer mechanism is provided at the bottom of the inner wall of the connecting box and connected to the bottom of the housing. The housing is located on the inner surface of the connecting box. A second buffer mechanism is provided between the two sides of the inner wall of the connecting box, and the second buffer mechanism is connected to the first buffer mechanism and extends into the horizontal groove. Heat dissipation fins are connected to the top of the inner wall of the housing.

[0007] Through the above technical solution: pulling the two locking mechanisms releases the locking of the mounting component, and pulling the mounting component separates it from the four connecting components, the mounting component can be disassembled, facilitating the maintenance of the two heat dissipation components. The mounting component is then placed back on the front of the housing and inserted into the four connecting components for initial installation positioning. Releasing the two locking mechanisms will lock the mounting component, thus completing the fixed installation of the mounting component. Vibration force is pressed down on the first buffer mechanism to compress it, providing initial buffering of the vibration force. The compression of the first buffer mechanism simultaneously squeezes the second buffer mechanism for further compression, thus providing further buffering of the vibration force. This provides good protection and shock absorption for the motor, controller, and two heat dissipation components. The two heat dissipation components blow air onto the heat dissipation fins to cool the motor.

[0008] The present invention is further configured such that the connecting component includes a positioning block and a positioning hole, the positioning block is connected to the top of the inner wall of the outer shell, and the positioning hole is opened on the front of the positioning block.

[0009] The above technical solution allows for the initial fixation of the mounting components by inserting them into the positioning holes and fitting them against the positioning blocks.

[0010] The present invention is further configured such that the locking mechanism includes a slide rod, a pull handle, an inclined block, and a return spring. The slide rod is slidably connected to one side of the inner wall of the placement groove, and the two ends of the slide rod extend to one side of the outer shell and the outside of the placement groove, respectively. The pull handle is connected to one end of the slide rod, the inclined block is connected to the other end of the slide rod, and the return spring is connected between one side of the inclined block and one side of the inner wall of the placement groove.

[0011] The above technical solution involves pulling the handle to slide the slide rod against the inner wall of one of the placement slots, causing the inclined block to be removed from the mounting component. This releases the lock on the mounting component, and the handle with a return spring will be compressed. Releasing the handle will reset the return spring, causing the inclined block to be reinserted into the mounting component, thus completing the fixation of the mounting component.

[0012] The present invention is further configured such that the mounting assembly includes a mounting plate, four positioning rods, a handle, and two slots. The mounting plate is placed on the front of the housing, the four positioning rods are all connected to the four corners of the back of the mounting plate, and one of the positioning rods is movably inserted into the inside of the positioning hole. The handle is connected to the front of the mounting plate, and the two slots are respectively opened on both sides of the mounting plate, and the inclined block is movably inserted into the inside of one of the slots.

[0013] The above technical solution involves using two locking mechanisms to remove the two slots, and simultaneously pulling the handle to remove the four positioning rods from the four connecting components, thus completing the disassembly of the mounting plate. The four positioning rods are then reinserted into the four connecting components to initially secure the mounting plate. Finally, the two locking mechanisms are released and reinserted into the two slots to secure the mounting plate, completing the installation.

[0014] The present invention is further configured such that the first buffer mechanism includes a shock-absorbing plate and four spring dampers. The shock-absorbing plate is connected to the bottom of the outer shell, and the four spring dampers are all connected to the bottom of the shock-absorbing plate, and the bottom ends of the four spring dampers are all connected to the bottom of the inner wall of the connecting box.

[0015] The above technical solution allows for the initial buffering of vibration force by compressing the four spring dampers through the pressure of the damping plate.

[0016] The present invention is further configured such that the second buffer mechanism includes a U-shaped seat, a crossbar, two sliders, two connecting shafts, a first damping spring, and two second damping springs. The U-shaped seat is connected to the bottom of the shock-absorbing plate, the crossbar is connected between the two sides of the inner wall of the connecting box, the two sliders are slidably connected to the outer surface of the crossbar, and the two sliders extend to the bottom of the transverse groove. One end of each of the two connecting shafts is hinged inside the U-shaped seat, and the other end of each connecting shaft is hinged to the top of the two sliders respectively. The first damping spring is connected between the two sliders, and the two second damping springs are respectively connected to the two sides of the inner wall of the connecting box, and one end of each of the two second damping springs is connected to the opposite side of the two sliders respectively.

[0017] The above technical solution involves moving the U-shaped seat downwards to cause the other ends of the two connecting shafts to rotate in opposite directions, thereby driving the two sliders to slide on the outer surface of the crossbar. This causes the first damping spring to stretch and the two second damping springs to compress, thus further buffering the vibration force.

[0018] The present invention is further configured such that both the second damping spring and the first damping spring are located outside the crossbar.

[0019] The above technical solution enables the two sliders to push the two second damping springs and the crossbar to compress and stretch respectively.

[0020] The present invention is further configured such that multiple air outlets are provided on the back of the outer casing.

[0021] The above technical solution allows for the discharge of hot air from inside the casing by using multiple air outlets.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. With the help of four connecting components, two locking mechanisms and installation components, the present invention enables workers to easily disassemble and install the two heat dissipation components, thereby facilitating their maintenance and replacement and improving the efficiency of maintaining the two heat dissipation components.

[0024] 2. In this utility model, the first buffer mechanism and the second buffer mechanism can effectively reduce the impact on the motor, controller and two heat dissipation components through double buffering, thereby reducing the damage to them, ensuring their normal operation and extending their service life.

[0037] Reference Figure 1-7An integrated heat dissipation structure for a new energy drive assembly includes a housing 1 and a connecting box 8. Two connecting components 2 are respectively connected to the top and bottom of the inner wall of the housing 1. Placement slots are provided on both sides of the housing 1, and locking mechanisms 3 are provided inside each of the two placement slots, extending to the outside of the placement slots. An installation component 4 is provided on the front of the housing 1, and the installation component 4 is movably inserted into the four connecting components 2. The two locking mechanisms 3 are movably inserted into the installation component 4. Two heat dissipation components 5 are provided on the installation component 4. A horizontal groove is provided at the bottom of the inner wall of the connecting box 8. A first buffer mechanism 6 is provided at the bottom of the inner wall of the connecting box 8 and is connected to the bottom of the housing 1. The housing 1 is located on the inner surface of the connecting box 8. A second buffer mechanism 7 is provided between the two sides of the inner wall of the connecting box 8, and the second buffer mechanism 7 is connected to the first buffer mechanism 6 and extends into the interior of the horizontal groove. The top of the inner wall is connected to heat dissipation fins 9. By pulling the two locking mechanisms 3, the locking of the mounting component 4 can be released. At this time, the mounting component 4 can be separated from the four connecting components 2 to complete the disassembly of the mounting component 4, which facilitates the maintenance of the two heat dissipation components 5. The mounting component 4 is placed back on the front of the outer shell 1 and inserted into the four connecting components 2 for initial installation and positioning. Releasing the two locking mechanisms 3 will lock the mounting component 4, thus completing the fixed installation of the mounting component 4. When the outer shell 1 vibrates, the vibration force will press the first buffer mechanism 6 to compress and initially buffer the vibration force. The compression of the first buffer mechanism 6 will also squeeze the second buffer mechanism 7 for further compression, thereby further buffering the vibration force. This provides good protection and shock absorption for the motor, controller and the two heat dissipation components 5. The air is blown to the heat dissipation fins 9 through the two heat dissipation components 5 to dissipate heat from the motor.

[0038] To facilitate the disassembly and assembly of the two heat dissipation components 5, refer to... Figure 3-6The connecting component 2 includes a positioning block 201 and a positioning hole 202. The positioning block 201 is connected to the top of the inner wall of the housing 1, and the positioning hole 202 is opened on the front of the positioning block 201. The locking mechanism 3 includes a slide rod 301, a pull handle 302, a wedge block 303, and a return spring 304. The slide rod 301 is slidably connected to one side of the inner wall of the placement groove, and both ends of the slide rod 301 extend to one side of the housing 1 and the outside of the placement groove, respectively. The pull handle 302 is connected to one end of the slide rod 301, and the wedge block 303 is connected to the... At the other end of the slide bar 301, a return spring 304 is connected between one side of the inclined block 303 and the inner wall of the groove. The mounting assembly 4 includes a mounting plate 401, four positioning rods 402, a handle 403, and two slots 404. The mounting plate 401 is placed on the front of the housing 1. The four positioning rods 402 are all connected to the four corners of the back of the mounting plate 401, and one of the positioning rods 402 is movably inserted into the inside of the positioning hole 202. The handle 403 is connected to the front of the mounting plate 401, and the two slots... 404 is respectively opened on both sides of the mounting plate 401, and the inclined block 303 is movably inserted into the inside of one of the slots 404. Pulling the handle 302 causes the slide rod 301 to slide on the inner wall of the placement slot, so that the inclined block 303 is withdrawn from the inside of one of the slots 404 and moves into the inside of the placement slot, releasing the lock on the mounting plate 401. At the same time, the return spring 304 will be squeezed. Grasp the handle 403 and pull to move the mounting plate 401 outward. At the same time, the positioning rod 402 will slide out from the inside of the handle 302, completing the disassembly of the mounting plate 401. At this time, the two heat dissipation components 5 on the mounting plate 401 can be inspected, maintained and replaced. Align the positioning rod 402 with the handle 302 and insert it into the inside of the handle 302 to initially fix the mounting plate 401. Release the handle 302, and the return spring 304 will reset, causing the inclined block 303 to be inserted into the inside of one of the slots 404, locking the mounting plate 401 again, thus completing the installation of the mounting plate 401.

[0039] In order to dampen vibrations in the motor, controller, and two heat dissipation components 5, refer to Figure 7The first buffer mechanism 6 includes a shock-absorbing plate 601 and four spring dampers 602. The shock-absorbing plate 601 is connected to the bottom of the outer shell 1, and the four spring dampers 602 are all connected to the bottom of the shock-absorbing plate 601. The bottom ends of the four spring dampers 602 are all connected to the bottom of the inner wall of the connecting box 8. The second buffer mechanism 7 includes a U-shaped seat 701, a crossbar 702, two sliders 703, two connecting shafts 704, a first damping spring 705, and two second damping springs 706. The U-shaped seat 701 is connected to the bottom of the shock-absorbing plate 601. The crossbar 702 is connected between the two sides of the inner wall of the connecting box 8. The two sliders 703 are slidably connected to the outer surface of the crossbar 702, and both sliders 703 extend to the bottom of the transverse groove. One end of each of the two connecting shafts 704 is hinged inside the U-shaped seat 701, and the other end of each connecting shaft 704 is hinged to the top of the two sliders 703. The first damping spring 705 is connected between the two sliders 703, and the two second damping springs 706 are respectively connected to the two sides of the inner wall of the connecting box 8. One end of each of the two second damping springs 706 is connected to the opposite side of the two sliders 703. The two second damping springs 706 and the first damping spring 705 are all located outside the crossbar 702. The vibration force will be compressed by the damping plate 601 pressing the four spring dampers 602, which will buffer the vibration force for the first time. At the same time as the damping plate 601 is pressed, the other end of the two connecting shafts 704 will rotate in opposite directions and drive the two sliders 703 to slide in opposite directions on the outer surface of the crossbar 702 and the inner wall of the transverse groove, which will stretch the first damping spring 705 and compress the two second damping springs 706, which will buffer the vibration force again, thereby playing a role in buffering and damping the motor, controller and two heat dissipation components 5.

[0040] To dissipate heat from the motor and controller, refer to Figure 1 Multiple air vents 10 are provided on the back of the outer casing 1, which allow the hot air inside the outer casing 1 to be discharged.

[0041] Working principle: When it is necessary to disassemble the two heat dissipation components 5, the operator pulls the handle 302. The handle 302 drives the slide bar 301 to slide on the inner wall of the placement slot, causing the inclined block 303 to retract from one of the slots 404 and move into the placement slot, thereby releasing the lock on the mounting plate 401. At the same time, the return spring 304 will be compressed. At this time, the operator holds the handle 403 and pulls it, thereby moving the mounting plate 401 outward. Simultaneously, the positioning rod 402 will slide out from the handle 302, thus completing the disassembly of the mounting plate 401. At this time, the operator can inspect, maintain, or replace the two heat dissipation components 5 on the mounting plate 401. After the inspection is completed, the positioning rod 402 is aligned with the handle 302 and inserted into the handle 302 to initially fix the mounting plate 401. Pull handle 302 and reset spring 304 will reset and drive wedge block 303 to insert into one of the slots 404, locking mounting plate 401 again, thus completing the installation of mounting plate 401. During the movement of connecting box 8, the vibration force generated by the outer shell 1 will be compressed by the damping plate 601 pressing the four spring dampers 602, thus buffering the vibration force initially. At the same time, the damping plate 601 will cause the other ends of the two connecting shafts 704 to rotate in opposite directions, thereby driving the two sliders 703 to slide in opposite directions on the outer surface of the crossbar 702 and the inner wall of the cross groove, thus stretching the first damping spring 705, while the two second damping springs 706 will be compressed, thus buffering the vibration force again, thereby achieving the function of buffering and damping the motor, controller and two heat dissipation components 5.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
