Description

Technical Field

[0001] The invention relates to the technical field of waste heat heating, and more specifically to a waste heat heating device for a motor of a new energy vehicle. Background Art

[0002] The main power of new energy vehicles comes from dedicated motors. When new energy vehicles are driving, the motors will work, and the temperature of the motors will gradually increase. New energy vehicles can use dedicated waste heat heating devices to guide the heat generated by the motors to the interior of the vehicle, thereby using the heat energy of the motors to heat the interior of the vehicle. This can effectively save energy and balance the temperature of the motors. In summary, the inventors have found that the existing heating devices mainly have the following defects: since the current motor waste heat heating device cannot completely wrap the battery of the new energy vehicle, it is only connected to the side of the motor compartment through a connecting pipe to communicate with the motor. Therefore, when the waste heat is recovered, part of the heat of the motor will be lost due to the gap in the side area, which will reduce the stability and integrity of the waste heat recovery, and ultimately cause part of the heat of the motor to be wasted.

The center of the upper end of the block body 6252 is also connected with an insert block 6253 , and the surface of the insert block 6253 also carries a locking bolt 6254 .

[0040] The base 11 is also provided with a vertical column 111, the upper end of the vertical column 111 is fixedly connected to the left and right surfaces of the lower end of the parallel plate 112, a protrusion 113 is connected to the center of the surface of the parallel plate 112 to allow the shock absorbing frame 114 to be embedded, and a slot 115 is opened inside the shock absorbing frame 114 to allow the bottom of the motor to be embedded.

[0041] There are two vertical columns 111 under the parallel plate 112 and they are symmetrically arranged. The bump 113 is located in the middle of the surface of the parallel plate 112.

[0043] Among them, the slide rail 1122 is arranged in a horizontal straight line orientation, the connecting frame 1123 is provided with two groups whose number is the same as the vertical column 111, and a slider 1124 is provided on each side of the connecting frame 1123. The slider 1124 slides linearly through the slide rail 1122 and is embedded in the connecting frame 1123 and fixed to the top of the vertical column 111.

[0044] Specific functions and operation procedures of this embodiment: In the present invention, the waste heat function device of the new energy vehicle motor can be connected to the inside of the vehicle air conditioner through the top of the connecting pipe 5, and then the heat energy of the waste heat recovery body 4 can be accurately input into the vehicle air conditioner by using the directional fan 6 to guide the waste heat recovery body 4 to achieve the waste heat heating effect. Then, the waste heat recovery body 4 can be combined with the activated carbon filter plate 3 and the guide pipe 2 to stably guide the heat energy generated by the motor inside the fully covered cabin 1. During the process, the activated carbon filter plate 3 can intercept impurities in the heat energy, thereby improving the purity of the waste heat guidance. Then, the base 11 of the fully covered cabin 1 can install the bottom cabin 12 in parallel with the vehicle motor area, and then the bottom cabin 12 is combined with the loading slot 13 to connect the bottom of the motor, and at the same time, the top cabin 16 is vertically embedded to cover the top of the motor, so that it can be achieved. The effect of fully covering the motor avoids incomplete waste heat recovery caused by excessive space gaps. After the top cabin 16 and the bottom cabin 12 are spliced, the front and rear ends will generate connection holes 14 and 15 to allow the motor accessories and the guide pipe 2 to be linearly embedded and connected, so that the motor can be stably electrically connected to the car after full coverage and fixation. Then, the adsorption frame 161 installed on the bottom layer of the covering body 162 of the top cabin 16 can overlap with the edge of the surface of the bottom cabin 12, and the characteristic of easy connection can be achieved according to the adsorption effect. At the same time, the multiple groups of positioning frames 163 installed on the outer surface of the covering body 162 can position the circular clamp ring 164, so that the power circuit carried by the motor can be penetrated and clamped through the circular clamp ring 164, and the power-on effect can be avoided. When the lines are arranged, the air tightness of the motor's coverage is destroyed again due to the gap, which improves the stability of the full coverage waste heat recovery effect. Subsequently, the insulating wall 1621 inside the covering body 162 can allow the top of the motor to be vertically embedded through the groove 1622. At the same time, the assembly rod 1624 is laterally fixed in combination with the positioning blocks 1623 on the left and right sides. The insulating block 1625 carried by the assembly rod 1624 can be embedded in the assembly rod 1624 through the plug block 6253 on the top of the block 6252, so that the locking bolt 6254 will penetrate the assembly rod 1624 to lock it, achieving the effect of easy disassembly and assembly, so that the contact layer 6251 of the block 6252 can cover the top edge area of ​​the motor to form a clamping shape, ensuring that the motor will not be damaged by the car after it is fully covered. During operation, the motor 1 vibrates and continuously collides with the inner wall of the fully covered cabin 1 to produce abnormal noise, which improves the stability of the waste heat heating device. Then, the parallel plate 112 on the base 11 at the bottom of the bottom cabin 12 can be vertically embedded in the automobile motor installation area through the bottom vertical column 111, and then the convex block 113 on the parallel plate 112 can be embedded in the bottom center of the shock-absorbing frame 114, so that the shock-absorbing frame 114 can allow the bottom of the motor to be embedded through the slot 115. At the same time, the groove 1622 of the covering body 162 can effectively limit the upper and lower parts of the motor vertically and stably, which improves the position fixation of the motor and the stable recovery of its heat energy. Then, the lower layer of the parallel plate 112 can arrange the slide rail 1122 in a horizontal straight line through the polishing layer 1121.The connection frames 1123 on the left and right sides of the slide rail 1122 allow the top of the vertical column 111 to be embedded, and then the sliders 1124 on the edge are clamped or disassembled, so that the sliders 1124 can slide horizontally in the slide rail 1122 area by manual operation, and the top of the vertical column 111 can be fixed or disassembled by detaching from the connection frame 1123 or embedding in the edge of the connection frame 1123. At the same time, the sliding accuracy and parallelism of the sliders 1124 can be improved according to the cooperation of the slide rail 1122.
