[0003] Among them, a controller is needed to control the cooling fan, and a connecting wire and a plug are needed to connect the controller and the fan. However, after the existing plug is connected to the controller, when the car is driving on a bumpy road, the controller is shaken and the plug is easily loosened, which may affect the normal operation of the cooling fan. Therefore, the relevant technology needs to be improved. Utility Model Content

[0006] By adopting the above technical solution, the connecting plug passes through the first mounting port and the second mounting port to connect the fan controller body to the automobile cooling fan. The provision of the anti-detachment component fully reduces the probability of the connecting plug becoming loose when the vehicle is bumpy or the controller is subjected to external force or shaking, which is conducive to ensuring the normal use of the fan controller body.

[0007] Furthermore, the anti-detachment components are provided in two groups and are symmetrically distributed on both sides of the protective frame. Each group of the anti-detachment components includes a protective frame fixed at a position at the bottom of the horizontal plate close to the first mounting port and an arc-shaped memory metal sheet arranged on the inner wall of the protective frame and used to press against the outer wall of the connecting plug. The arc-shaped memory metal sheet is arched toward the side away from the inner wall of the protective frame.

[0008] By adopting the above technical solution, the arc-shaped memory metal sheet has a certain elasticity and can restore its deformation after being subjected to a small external force. After the connecting plug passes through the first installation port and is plugged into the center plug, the arched part of the arc-shaped memory metal sheet is tightly pressed against the outer wall of the connecting plug, which enhances the stability of the plug-in between the connecting plug and the center plug to a certain extent.

After the connecting plug squeezes the arc-shaped memory metal sheet, the arc-shaped memory metal sheet acts on the two sliding plates and makes them move away from each other. After slightly compressing the rubber block, the connecting plug and the center plug are plugged in. Subsequently, the rubber block and the arc-shaped memory metal sheet are reset, so that the arc-shaped memory metal sheet remains in a state of being tightly pressed against the connecting plug, so as to enhance the stability of the connection between the memory metal sheet and the connecting plug.

[0011] Furthermore, the anti-slip assembly also includes a spring fixed to one end of the two sliding plates close to each other, and the spring is located between the arc-shaped memory metal sheet and the inner wall of the protection frame.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] like Figure 1-6 As shown, an embodiment of the present application discloses a circuit connection structure of an automobile cooling fan controller, including a fan controller body 1, at the bottom of which a center plug 11 and a side plug 12 electrically connected to a control chip inside the fan controller body 1 are arranged.

[0031] The fan controller body 1 is also provided with an anti-slip mechanism 2 at the bottom, and the anti-slip mechanism 2 includes an installation component 21 and an anti-slip component 22. The installation component 21 includes a horizontal plate 211, a buckle plate 212 hinged to the top of the horizontal plate 211, and a fixing block 213 fixed to the side wall of the fan controller body 1 near the bottom of the fan controller body 1. The buckle plate 212 is provided with a through hole 2121 for buckling with the fixing block 213. The horizontal plate 211 is provided with a first installation port 2111 at a position corresponding to the center plug 11. The horizontal plate 211 is connected to the side plug 11. A second mounting port 2112 is provided at a position corresponding to the head 12. The anti-slip assembly 22 is provided on the horizontal plate 211 and is used to prevent the connection plug connecting the fan controller body 1 and the automobile cooling fan from loosening (the connection plug usually has three terminals, the middle terminal is plugged into the center plug 11, and the plug terminals on both sides are respectively plugged into the side plugs 12 on both sides. When the anti-slip assembly 22 is introduced later, only the plug-in and anti-slip between the middle terminal and the center plug 11 will be described. The same layout structure can be used to prevent the plug terminals on both sides from loosening). The connection plug passes through the first mounting port 2111 and the second mounting port 2112 to connect the fan controller body 1 to the automobile cooling fan. The provision of the anti-slip assembly 22 fully reduces the probability of the connection plug loosening when the vehicle is bumpy and the controller is subjected to external force or shaking, which is conducive to ensuring the normal use of the fan controller body 1.

[0032] There are two groups of anti-slip components 22 and they are symmetrically distributed on both sides of the protection frame 221. Each group of anti-slip components 22 includes a protection frame 221 fixed at the bottom of the horizontal plate 211 near the first installation port 2111 and an arc-shaped memory metal sheet 222 arranged on the inner wall of the protection frame 221 and used to press against the outer wall of the connecting plug. The arc-shaped memory metal sheet 222 is arched toward the side away from the inner wall of the protection frame 221. The arc-shaped memory metal sheet 222 has a certain elasticity and can restore its deformation after being subjected to a small external force. After the connecting plug passes through the first installation port 2111 and is plugged into the center plug 11, the arched part of the arc-shaped memory metal sheet 222 presses against the outer wall of the connecting plug, which enhances the plugging stability between the connecting plug and the center plug 11 to a certain extent.

[0033] The anti-slip assembly 22 also includes an L-shaped slide rail 223 fixed on the inner wall of the protection frame 221, and two L-shaped slide rails 223 are provided and symmetrically arranged. The anti-slip assembly 22 also includes an end cover plate 224 fixed between the two L-shaped slide rails 223 and a sliding plate 225 slidably installed between the two L-shaped slide rails 223. Both the end cover plate 224 and the sliding plate 225 are provided with two and symmetrically arranged. The end cover plate 224 is located near the end of the L-shaped slide rail 223. A rubber block 226 is fixed on the side wall of the end cover plate 224 near the sliding plate 225. The two ends of the arc-shaped memory metal sheet 222 are respectively fixed to the two sliding plates 225. The rubber block 226 is made of rubber material and has good elastic properties. After the connecting plug squeezes the arc-shaped memory metal sheet 222, the arc-shaped memory metal sheet 222 acts on the two sliding plates 225 and makes them move away from each other. After slightly compressing the rubber block 226, the connecting plug and the center plug 11 are connected. Subsequently, the rubber block 226 and the arc-shaped memory metal sheet 222 are reset, so that the arc-shaped memory metal sheet 222 remains in a state of being tightly pressed against the connecting plug, so as to enhance the stability of the connection between the memory metal sheet and the connecting plug.

[0034] The anti-drop assembly 22 also includes a spring 227 fixed to one end of the two sliding plates 225 that is close to each other. The spring 227 is located between the arc-shaped memory metal sheet 222 and the inner wall of the protection frame 221, which is conducive to the rapid reset of the two sliding plates 225.

[0035] A rubber sheet 3 is fixed to the surface of the arc-shaped memory metal sheet 222 away from the inner wall of the protection frame 221. The rubber sheet 3 is made of rubber material and has certain elasticity, which reduces the friction damage between the connection plug and the memory metal sheet.

[0036] In order to enhance the connection firmness between the buckle plate 212 and the fixing block 213, an annular rubber plate 4 is fixed on the upper surface of the horizontal plate 211 near its edge, and the top of the annular rubber plate 4 is pressed against the bottom of the fan controller body 1. The fixing block 213 is tilted, and the height of the fixing block 213 away from the fan controller body 1 is greater than the height of the fixing block 213 close to the fan controller body 1.

[0037] In order to facilitate the staff to disassemble the installation assembly 21 later, the side walls on both sides of the horizontal plate 211 are fixed with pressing plates 5, so that the staff can press the horizontal plate 211 upward through the pressing plates 5, so that the horizontal plate 211 is matched with the bottom of the fan controller body 1 and compresses the annular rubber plate 4, thereby separating the pinch plate 212 from the fixing block 213, so as to disassemble the installation assembly 21. The provision of the annular rubber plate 4 enables the horizontal plate 211 to match with the bottom of the fan controller body 1 and press against the annular rubber plate 4 after the through hole 2121 on the pinch plate 212 is buckled with the fixing block 213, thereby enhancing the buckling effect between the fixing block 213 and the pinch plate 212.

[0038] The use principle of a car cooling fan controller circuit connection structure in this embodiment is: the connecting plug passes through the first mounting port 2111 and the second mounting port 2112 to connect the fan controller body 1 to the car cooling fan. The provision of the anti-detachment component 22 fully reduces the probability of the connecting plug becoming loose when the vehicle is bumpy or the controller is subjected to external force or shaking, which is conducive to ensuring the normal use of the fan controller body 1.
