DETAILED DESCRIPTION

[0024] The application will be further described below in detail with reference to the drawings and examples. It can be understood that the specific examples described herein are only used to explain the related application, and not to limit the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for ease of description.

[0025] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0026] Example 1

[0027] As mentioned in the background, in view of the problems in the prior art, the present application provides a vehicle-mounted power module assembly device, as shown in Figures 1-4 The protection shell 4 is provided on the top outer wall of the power supply assembly 1, and the cooling pipe 3 is installed in the protection shell 4. The cooling pipe 3 extends to the outside of the protection shell 4 at both ends and is connected with the conveying pump 5.

[0028] A plurality of protection assemblies are provided on the top of the protection shell 4. Each protection assembly includes a sleeve 9 fixed to the top of the protection shell 4, a piston rod 7 slidably installed in the sleeve 9, a spring 18 fixed to the protection shell 4 at one end and to the piston rod 7 at the other end, and a cushion pad 6 fixed to the top end of the piston rod 7 by a mounting plate 8. The power supply assembly 1 has sponge pads 10 fixed to the outer walls on both sides.

[0029] The top buffering structure of the present embodiment is designed by the mechanical linkage of the sleeve 9, the spring 18, the piston rod 7 and the rubber cushion pad 6 to absorb the impact force. The sponge pads 10 are provided on both sides of the power supply assembly 1 to provide lateral flexible buffering. The cooling pipe 3 is embedded in the protection shell 4 to form a circulating cooling system with the conveying pump 5, and the protection shell 4 also has a protection function.

[0030] Specifically, when the top of the device is impacted, the buffer pad 6 absorbs the impact first, while the piston rod 7 slides within the sleeve 9, cooperating with the elastic deformation of the spring 18 to dissipate the impact energy step by step, preventing direct damage to the power assembly 1. The side sponge pad 10 buffers lateral impacts through flexible deformation, preventing internal circuit breakage or short circuits caused by external impacts, significantly reducing maintenance costs and fire risk. Heat dissipation and protection are optimized in tandem: the protective shell 4 encloses the cooling pipe 3, protecting the cooling components from external damage while achieving efficient heat dissipation through coolant circulation and the heat dissipation port 15, solving the problem of separation between heat dissipation and protection in traditional designs, and ensuring stable operation under high power.

[0031] When in use, the device can be installed and fixed by aligning the screw holes of the fixing bracket 11 with the bolts at the installation location, inserting the bolts and tightening the nuts. After installation, the wiring can be connected to the power assembly 1 for normal operation. After adding coolant to the cooling pipe 3, one end is connected to the return pipe. The return pipe passes through the condenser and is connected to the delivery pump 5. The delivery pump 5 can circulate the coolant in the cooling pipe 3. The cooling pipe 3 is made of copper, which gives it good thermal conductivity. The heat generated by the power assembly 1 during operation can be carried away by the flow of coolant. After being cooled by the condenser, it returns to the condenser. After the cycle is completed, continuous cooling is achieved.

[0032] The protective assembly includes a sleeve 9, and multiple sets of sleeves 9 are provided, which are respectively fixed to the top outer wall of the protective shell 4 by bolts. A piston rod 7 is slidably installed at one end of the sleeve 9. A spring 18 is installed inside the sleeve 9. One end of the spring 18 is fixed to the protective shell 4, and the other end is fixed to the piston rod 7. An mounting plate 8 is installed at the top of the piston rod 7. A rubber buffer pad 6 is provided on the top of the mounting plate 8. Sponge pads 10 are installed on both sides of the power assembly 1.

[0033] During use, the sponge pad 10 can provide protection for both sides of the device, which can buffer and protect the device from damage when the sides are impacted. When the top of the device is impacted, the rubber buffer pad 6 can provide initial buffering. Then, the piston rod 7 slides and the elastic force of the spring 18 inside the sleeve 9 can dissipate the impact, thus providing effective protection for the device and avoiding the problem of needing to bear unnecessary maintenance costs due to impact damage. At the same time, it avoids the safety hazard of fire caused by internal leakage of the power assembly 1 due to damage to the power assembly 1.

[0034] To facilitate heat dissipation, such as Figure 2 As shown, the power supply assembly 1 has a heat dissipation vent 15 at the bottom, and multiple sets of heat dissipation vents 15 are arranged in sequence.

[0035] During use, multiple sets of heat dissipation vents 15 are set to facilitate the removal of heat generated during device operation. The heat dissipation vents 15 and cooling pipes 3 are set to better dissipate heat and facilitate temperature control when the power is high.

[0036] In order to further increase the heat dissipation efficiency, as shown in Figure 4 The inner wall of one side of the power assembly 1 is provided with a rotating motor 19 fixed by bolts, the bottom of the rotating motor 19 is connected with a rotating shaft 21, and the one end of the rotating shaft 21 is provided with a fan blade 20.

[0037] In use, the rotation of the rotating shaft 21 and the fan blade 20 can be started and controlled by the rotating motor 19 to increase the air flow, thereby increasing the heat dissipation efficiency, and avoiding the overheating of the device when the power is high.

[0038] In order to make the fixing of the device more firm and stable, as shown in Figure 4 The bottom of the fixing support 11 is provided with a gasket 12 made of rubber material.

[0039] In use, the gap at the fixed position can be filled by the gasket 12 made of rubber material when the device is fixed by the fixing support 11, so that the fixing is more firm and the shaking after fixing is avoided.

[0040] In order to control the fire when it breaks out, as shown in Figure 2 The outer wall of the bottom of the power assembly 1 is provided with a storage bin 2 fixed by bolts, and the one side of the storage bin 2 is connected with a spray head 14.

[0041] In use, carbon dioxide is injected into the storage bin 2, and an electromagnetic valve is arranged in the storage bin 2. When the device breaks out due to an accident, the stored carbon dioxide is sprayed out through the spray head 14 by opening the electromagnetic valve, which can reduce or extinguish the fire, thereby gaining time for rescue and escape. The detection and judgment of whether a fire breaks out can be carried out by connecting any existing device such as a smoke alarm and an infrared sensor. This is a common existing device, which will not be described in detail. Those skilled in the art can undoubtedly infer this method. When a fire breaks out is detected by the device such as a smoke alarm and an infrared sensor, the rotating shaft 21 and the fan blade 20 are stopped from rotating by controlling the rotating motor 19, and then the stored carbon dioxide is sprayed out through the spray head 14 by opening the electromagnetic valve, which can reduce or extinguish the fire. Compared with manually taking a fire extinguisher, this method is more convenient, faster and safer.

[0042] In order to facilitate the movement of the device, as shown in Figure 4 The power assembly 1 is provided with a pull ring 13 fixed by bolts at both ends.

[0043] In use, when the device needs to be moved, the operator can hold the pull ring 13 to operate, which is more convenient for moving the device and can reduce the occurrence of dropping the device.

[0044] Example 2

[0045] In order to monitor the temperature, reference is made to Figure 3 A vehicle-mounted power module assembly device, compared with embodiment 1, the following improvements are made, the top outer wall of the power assembly 1 is provided with a temperature sensor 16 fixed by bolts;

[0046] In use, the temperature can be monitored in real time during the operation of the device through the temperature sensor 16, so as to facilitate the judgment of whether there is a fault according to the temperature value, facilitate the timely discovery of the fault, when the fault occurs, the temperature of the power assembly 1 will appear a rapid rise compared with the original normal temperature, the continuously rising temperature cannot be affected by the cooling pipe 3, therefore, only the rapid change of the temperature needs to be monitored to judge whether the device has a fault, so as to take corresponding measures.

[0047] The principles and implementation modes of the present application are described by applying specific examples in this paper, and the above examples are only used to help understand the method and its core idea. The above description is only the preferred embodiment of the present application, it should be pointed out that due to the limitation of language expression, there are infinite specific structures, for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements, refinements or changes can be made, and the above technical features can be combined in an appropriate way; these improvements, refinements, changes or combinations, or the application of the concept and technical scheme of the present application to other occasions without improvement, should be regarded as the protection scope of the present application.
