Technical Field

[0001] This utility model relates to the field of electric vehicle range extender technology, specifically to an electric vehicle range extender with a heat dissipation structure. Background Technology

[0002] An electric vehicle range extender is an emergency device that provides additional electrical energy to extend the driving range of an electric vehicle. When the battery power of an electric vehicle is insufficient to support the vehicle to its destination, the range extender will start, using the engine to drive a generator to generate electricity, and then transmitting the electrical energy to the battery or directly supplying the electric motor, thereby extending the vehicle's driving distance.

[0003] To prevent damage, most existing electric vehicle range extenders are protected by protective cases. However, these cases are often difficult to disassemble, making them inconvenient to use. Furthermore, the cases tend to trap heat inside, resulting in poor heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide an electric vehicle range extender with a heat dissipation structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An electric vehicle range extender with a heat dissipation structure includes a protective box body, the protective box body including a box shell, a sealing cover plate detachably installed on the top of the box shell, and a heat dissipation vent on the front side of the box shell.

[0007] The electric vehicle range extender body is detachably installed inside the outer shell of the housing.

[0008] The top two sides of the outer casing are equipped with disassembly and assembly mechanisms, and the interior of the heat dissipation vent is equipped with a heat dissipation and dust removal mechanism.

[0009] A further improvement of this utility model is that the heat dissipation and dust removal mechanism includes a support bracket fixedly installed on the inner side of the inner wall of the heat dissipation port, and a dustproof net is fixedly installed on the outer side of the inner wall of the heat dissipation port. The support bracket can support the cooling fan.

[0010] A further improvement of this utility model is that: a motor is fixedly installed at the middle position of the support bracket, a cooling fan is fixedly installed at the output end of the motor, and a drive rod is fixedly installed at the middle position of the cooling fan.

[0011] A further improvement of this utility model is that: a rotating shaft is fixedly sleeved on the outer surface of the other end of the drive rod, and dust scrapers are fixedly connected on both outer surfaces of the rotating shaft. The dust scrapers are provided in two sets, located on the inner and outer surfaces of the dustproof net, and the dust scrapers can clean the dust adhering to the dustproof net.

[0012] A further improvement of the present invention is that the disassembly and assembly mechanism includes movable grooves opened on both sides of the top of the housing, and locking blocks are fixedly installed on the inner walls of the grooves on both sides of the bottom end of the sealing cover.

[0013] A further improvement of the present invention is that a pressing and fixing block is movably inserted into the front end of the moving groove, the top of the pressing and fixing block is provided with an inclined surface, and the front side of the pressing and fixing block is provided with a locking groove below the inclined surface, so that the inclined surface facilitates the locking block to move downward and lock.

[0014] A further improvement of this utility model is that: a return spring is fixedly installed on both sides of the rear of the compression fixing block, and the other end of the return spring is fixedly installed on the inner wall of the moving groove. The elastic potential energy of the return spring can promote fixation and prevent detachment when it is engaged.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] This utility model provides an electric vehicle range extender with a heat dissipation structure. By setting heat dissipation vents, the heat emitted by the electric vehicle range extender body can be discharged to the outside. In conjunction with the rotation of the cooling fan, the suction force generated further enables the internal heat to be discharged to the outside quickly, thereby improving the heat dissipation rate.

[0017] This utility model provides an electric vehicle range extender with a heat dissipation structure. By setting a dustproof net, it can prevent external dust from entering the interior. When the cooling fan rotates, it can drive the drive rod to rotate as well. The drive rod drives the rotating shaft to make the dust scraper rotate as well, which facilitates the scraping of dust adhering to the dustproof net, prevents the mesh from being blocked, and improves the heat dissipation efficiency.

[0018] This utility model provides an electric vehicle range extender with a heat dissipation structure. By setting a sealing cover plate that is correspondingly engaged with the top of the housing shell, the engaging groove is sleeved on the outer surface of the engaging block, which can fix the connection between the two and thus achieve the effect of quick assembly and disassembly.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] like Figure 1-5 As shown, this utility model provides an electric vehicle range extender with a heat dissipation structure, including a protective box body 1, a box shell 2, a sealing cover 3 detachably installed on the top of the box shell 2, a heat dissipation vent 4 on the front side of the box shell 2, an electric vehicle range extender body 21 detachably installed inside the box shell 2, and disassembly and assembly mechanisms provided on both sides of the top of the box shell 2. A heat dissipation and dust removal mechanism is provided inside the heat dissipation vent 4, which includes a support bracket 41 fixedly installed on the inner side of the inner wall of the heat dissipation vent 4, a dustproof net 43 fixedly installed on the outer side of the inner wall of the heat dissipation vent 4, a motor fixedly installed in the middle of the support bracket 41, a cooling fan 42 fixedly installed on the output end of the motor, a drive rod 44 fixedly installed in the middle of the cooling fan 42, a rotating shaft 45 fixedly sleeved on the outer surface of the other end of the drive rod 44, and dust scrapers 46 fixedly connected to the outer surfaces of both sides of the rotating shaft 45. The dust scrapers 46 are provided with two sets located on the inner and outer surfaces of the dustproof net 43.

[0027] Furthermore, the heat generated by the electric vehicle range extender body 21 can be discharged outward through the heat dissipation vent 4, and the suction generated by the rotation of the cooling fan 42 can further facilitate the rapid discharge of internal heat, thereby improving the heat dissipation rate. In conjunction with the dustproof net 43, it can prevent external dust from entering the interior. When the cooling fan 42 rotates, it can drive the drive rod 44 to rotate as well. The drive rod 44 drives the rotating shaft 45 to cause the dust scraper 46 to rotate as well, which facilitates the scraping of dust adhering to the dustproof net 43 to prevent the mesh from becoming clogged. Example

[0028] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the disassembly and assembly mechanism includes a movable groove 22 opened on both sides of the top of the outer shell 2 of the box, and a locking block 31 is fixedly installed on the inner wall of the groove on both sides of the bottom end of the sealing cover plate 3. A pressing fixing block 23 is movably inserted into the front end of the movable groove 22. An inclined surface 24 is provided on the top of the pressing fixing block 23. A locking groove 25 is opened on the front side of the pressing fixing block 23 below the inclined surface 24. A return spring 26 is fixedly installed on both sides of the rear of the pressing fixing block 23. The other end of the return spring 26 is fixedly installed on the inner wall of the movable groove 22.

[0029] Furthermore, when the electric vehicle range extender body 21 needs to be repaired, the pressing and fixing blocks 23 on both sides of the housing 2 can be pressed inward. At this time, the return spring 26 is in a contracted state, and the front locking groove 25 of the pressing and fixing block 23 disengages from the locking block 31 of the sealing cover 3, thereby releasing the fixing of the sealing cover 3 and facilitating the repair or replacement of the electric vehicle range extender body 21 inside.

[0030] The working principle of this electric vehicle range extender with a heat dissipation structure will be explained in detail below.

[0031] like Figure 1-5As shown, during use, the heat generated by the electric vehicle range extender body 21 can be discharged outward through the heat dissipation vent 4. The rotation of the cooling fan 42 generates suction, which further enables the internal heat to be discharged outward quickly, thereby improving the heat dissipation rate. The dustproof net 43 can prevent external dust from entering the interior. When the cooling fan 42 rotates, it can drive the drive rod 44 to rotate as well. The drive rod 44 drives the rotating shaft 45 to make the dust scraper 46 rotate as well, which facilitates the scraping of dust adhering to the dustproof net 43 to prevent the mesh from becoming clogged. When it is necessary to repair the electric vehicle range extender body 21, the pressing and fixing blocks 23 on both sides of the housing 2 can be pressed inward. At this time, the return spring 26 is in a contracted state, and the front locking groove 25 of the pressing and fixing block 23 disengages from the locking block 31 of the sealing cover 3, releasing the fixing of the sealing cover 3, which facilitates the repair or replacement of the electric vehicle range extender body 21 inside.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
