[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments.

[0032] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0033] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0034] Combine Figures 1 to 5 As shown, an embodiment of the present invention provides a heat dissipation structure, which is applied to a drive, including a windshield assembly 100, a heat dissipation base 200 and a heat sink group 300. The windshield assembly 100 and the heat sink group 300 are both arranged on the heat dissipation base 200. A fan mounting groove 400 is provided on the end of the heat dissipation base 200 close to the heat sink group 300. One end of the windshield assembly 100 is located on the side of the fan mounting groove 400. The heat dissipation structure also includes a fan body 10, which is arranged in the fan mounting groove 400. The side wall of the windshield assembly 100 close to the fan body 10 is provided with an elastic member 101, which is used to clamp and fix the fan body 10.

[0035] In this embodiment, a gap is provided between one end of the windshield assembly 100 and the opposite end of the heat sink base 200, and the gap forms a fan mounting slot 400. The fan mounting slot 400 is located in the vicinity of the heat sink assembly 300 and is used to mount the fan body 10. The windshield assembly 100, the heat sink base 200 and the heat sink assembly 300 constitute an independent heat dissipation duct for the driver. The fan body 10 is directly mounted in the fan mounting slot 400, so that the fan body 10 can be closer to the heat sink assembly 300, thereby improving the heat dissipation effect. The side wall of the windshield assembly 100, that is, the part close to the fan body 10, is provided with an elastic member 101, and the elastic member 101 is designed to cooperate with the side wall of the fan body 10. The fan body 10 can be installed and fixed by inserting it into the fan mounting slot 400. When the fan body 10 needs to be removed, it can be removed by simply pulling the fan body 10 out of the fan mounting slot 400, which is simple and convenient to operate. This fixing method not only simplifies the installation process of the fan, but also makes it easier to disassemble the fan and prevents the fan body 10 from shifting under relatively small forces. The utility model effectively reduces the installation cost and subsequent maintenance cost of the heat dissipation structure. The entire disassembly and assembly process does not cause damage to the fan body 10, and the fan body 10 can be recycled, further reducing the cost of use.

[0036] In one embodiment, a slot 11 is provided on the outer wall of the fan body 10 , and the elastic member 101 is arched toward the fan body 10 to form an arched portion 1011 . The arched portion 1011 is retained in the slot 11 .

[0037] In this embodiment, a slot 11 is provided on the outer wall of the fan body 10, and an elastic member 101 is located at the edge of the windshield assembly 100 near the proximal side of the fan body 10. The elastic member 101 can cooperate with the slot 11 to fix the fan body 10. Specifically, the elastic member 101 arches toward the fan body 10 to form an arched portion 1011. The arched portion 1011 is designed to cooperate with the slot 11 on the outer wall of the fan body 10. When the fan body 10 is installed in the fan mounting slot 400, the arched portion 1011 extends into the slot 11. This holding effect ensures that the fan body 10 remains stable during operation and prevents displacement due to vibration or other external forces. In addition, since the elastic member 101 has a certain elasticity, when the fan body 10 needs to be disassembled, the arched portion 1011 can be removed from the slot 11, making the disassembly process of the fan body 10 simple and quick without the need for additional disassembly tools. The arched portion 1011 in this embodiment is an angular protrusion that is retained in the card slot 11 to improve the stability of the retention. Of course, it can also be designed to have other shapes, such as an arc-shaped protrusion to make the insertion and removal process smoother. The specific configuration can be based on actual conditions.

[0038] In one embodiment, the outer wall of the fan body 10 is an arc-shaped structure, and a fixing ear 12 is provided on the outer wall of the fan body 10. The slot 11 includes an arc-shaped slot formed between the fixing ear 12 and the arc-shaped structure, and the arched portion 1011 is clamped in the arc-shaped slot.

[0039] In this embodiment, the outer wall of the fan body 10 is designed to be an arc-shaped structure. A fixing ear 12 is further provided on the outer wall of the fan body 10. An arc-shaped slot is formed between the fixing ear 12 and the arc-shaped outer wall. The arc-shaped slot is designed to cooperate with the elastic member 101 on the windshield assembly 100 to facilitate the installation and fixation of the fan body 10. The arched portion 1011 of the elastic member 101 can be more smoothly clamped in this arc-shaped slot. When the fan body 10 is installed in the fan mounting slot 400, the arched portion 1011 is elastically clamped into the arc-shaped slot. The fan body 10 can be fixed by a simple insertion action without an additional fixing device, which greatly improves the installation efficiency. In specific application scenarios, the arched portion 1011 is an angular protrusion, while the retaining groove 11 is an arcuate retaining groove. This embodiment fully utilizes the characteristics of the outer wall of the fan body 10, making the insertion and removal process smoother while ensuring a secure fit. It avoids the difficulty of insertion or removal caused by the use of both an angular protrusion and an angular groove, and the unstable fixation caused by the use of both an arcuate protrusion and an arcuate retaining groove. When maintenance or replacement of the fan body 10 is required, the operator simply pulls the fan body 10 to release it from the arcuate retaining groove, making the operation simple and quick.

[0040] Combine Figure 6 and Figure 7 As shown, in one embodiment, a reinforcement portion 1012 is provided on a side of the elastic member 101 away from the fan body 10 , and the reinforcement portion 1012 is connected to the arched portion 1011 .

[0041] In this embodiment, the elastic member 101 is a part of the windshield assembly 100, and its main function is to fix the fan body 10. The design of the reinforcement portion 1012 is to improve the overall structural strength of the elastic member 101, so that the arched portion 1011 can provide a more solid support when clamping the fan body 10. The arched portion 1011 can be snapped into the arc-shaped slot on the fan body 10 to achieve quick and secure installation. The connection between the reinforcement portion 1012 and the arched portion 1011 not only increases the rigidity of the elastic member 101, but also improves its durability, especially during the process of multiple installation and removal of the fan body 10, effectively preventing the elastic member 101 from deformation or damage.

[0042] Combine Figure 8 and Figure 9As shown, in one embodiment, a deformation cavity 102 is provided at one end of the wind shield assembly 100 close to the fan body 10, and the deformation cavity 102 and the fan mounting groove 400 are respectively located on both sides of the elastic member 101. The elastic member 101 can be deformed into the deformation cavity 102 as the fan body 10 is squeezed.

[0043] In this embodiment, the deformation chamber 102 is intended to provide a movable space, allowing the elastic member 101 to deform when subjected to the squeezing force of the fan body 10. When installing the fan body 10, if the fan body applies pressure to the elastic member 101, the elastic member 101 will deform into the deformation chamber 102, making it easier to install the fan body 10 and the disassembly process simpler because the deformation chamber 102 provides additional movable space to accommodate the deformation of the elastic member 101 when it is released. In a specific application scenario, one end of the elastic member 101 is connected to the windshield assembly 100, while the other end is not connected to the windshield assembly 100. In this way, when the elastic member 101 is subjected to pressure, the other end can deform into the deformation chamber 102. Alternatively, both ends of the elastic member 101 can be connected to the windshield assembly 100, and the elastic force of the elastic member 101 itself can be used to cause the arched portion 1011 to deform into the deformation chamber 102 when subjected to pressure.

[0044] In one embodiment, a plurality of the card slots 11 are provided, and a plurality of the elastic members 101 are provided correspondingly.

[0045] In this embodiment, each slot 11 on the fan body 10 can hold a corresponding elastic member 101, thereby enhancing the stability and durability of the entire heat dissipation structure by dispersing the fixing force points. Each slot 11 is of arc-shaped design, matching the arched portion 1011 of the corresponding elastic member 101 on the windshield assembly 100. In addition, the provision of multiple elastic members 101 not only improves the fixing stability of the fan body 10, but also simplifies the installation and disassembly process. Because the multi-point connection reduces the load at each point, when the fan body 10 needs to be maintained or replaced, the operator can quickly unlock each slot 11, thereby quickly completing the disassembly. In this embodiment, the fan body 10 is arc-shaped as a whole and has four evenly distributed fixing ears, so two card slots 11 are formed on both sides of a fan body 10, forming a total of four card slots 11. When installed and used, all the card slots 11 can be used, or only some of the card slots 11 can be used. For example, an elastic member 101 can be set on the windshield assembly 100, and an elastic member 101 can also be set on the heat dissipation base 200. The two elastic members 101 are arranged relative to each other and are respectively clamped into the two card slots 11 of the fan body 10 for limit fixation.

[0046] In one embodiment, a first limiting plate 201 is provided at one end of the heat dissipation base 200 close to the fan body 10, and a second limiting plate 103 is provided at one end of the wind shield assembly 100 close to the fan body 10. The first limiting plate 201 and the second limiting plate 103 are arranged opposite to each other and are used to limit the fan body 10.

[0047] In this embodiment, the first limiting plate 201 and the second limiting plate 103 are positioned relative to each other to form a limiting mechanism for limiting the position of the fan body 10. This ensures that the fan body 10 is accurately installed and prevents displacement or vibration during operation. During installation, the fan body 10 is positioned between the first limiting plate 201 and the second limiting plate 103. The two limiting plates are relatively fixed to ensure that the fan body 10 is correctly fixed on the heat dissipation base 200.

[0048] In one embodiment, the first limiting plate 201 is disposed along a first direction, and the second limiting plate 103 is disposed along a second direction, wherein the first and second directions are perpendicular. Specifically, the first direction is a vertical direction, and the second direction is a horizontal direction. These two limiting plates are used to precisely limit the fan body 10 in multiple dimensions.

[0049] In one embodiment, the fan mounting slot 400 has an opening 401 at one end away from the heat dissipation base 200 . The opening 401 is connected to the fan mounting slot 400 , and the fan body 10 is inserted into the fan mounting slot 400 through the opening 401 .

[0050] In this embodiment, the fan body 10 can be directly inserted into the fan mounting slot 400 from the outside. This design simplifies the installation process of the fan body 10 and reduces the installation time. Once inserted into the fan mounting slot 400, the fan body 10 is secured by the first retaining plate 201, the second retaining plate 103, and the elastic member 101. When the fan body 10 needs maintenance or replacement, the operator can simply remove the fan body 10 through the opening 401, making the operation simple and quick.

[0051] Combine Figure 10 As shown, the present invention further provides a driver, which includes the heat dissipation structure and a housing 500 as described above, and the heat dissipation structure is arranged in the housing 500.

[0052] In this embodiment, the heat dissipation structure can be disposed within the housing 500, reducing the number of fixing components used to secure the fan body 10 and the space occupied by the fan body 10. This can lower the required installation space and save on materials, thereby reducing material costs and production and operating costs. Furthermore, the heat dissipation structure is fixed within the housing 500, which protects the heat dissipation structure.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
