Description

Technical Field

[0001] This application relates to the technical field of electric vehicle controllers, and in particular to a conductive heat dissipation quick-release structure for an electric vehicle controller. Background Technology

[0002] As the core control component of an electric vehicle, the controller generates a significant amount of heat during operation due to the power devices within it. Currently, the industry commonly uses heat-conducting columns as the heat transfer path to transfer heat to the metal casing or external heat sink for dissipation. A typical heat-conducting column is a smooth cylindrical structure with a large threaded hole at the top for connecting the power cord, and a small threaded hole at the bottom for fixing it to the PCB board.

[0003] As the power demands of electric vehicles continue to increase, the power consumption of controllers is increasing significantly, and heat dissipation issues are becoming increasingly prominent. Due to the limited internal space of the controller, it is impossible to expand the heat dissipation area by increasing the size of the guide columns. This results in excessive temperature rise of the guide columns under high-load operating conditions, making them a bottleneck for the heat dissipation of the entire system and seriously affecting the reliability and service life of the controller.

[0004] Furthermore, existing guide columns suffer from inefficiencies in installation and maintenance. Specifically, the threaded hole at the upper end typically uses a fine-pitch thread design, while the power cord end has a matching fine-pitch stud. This connection structure requires multiple rotation operations when assembling or replacing the power cord, resulting in low screw-in and screw-out efficiency, increasing assembly time and thus affecting work efficiency. Utility Model Content

[0005] To address the issues of insufficient heat dissipation area in traditional guide columns leading to excessive controller temperature rise, and low installation efficiency of threaded connections, this application provides a conductive heat dissipation quick-installation structure for electric vehicle controllers.

[0006] The conductive heat dissipation quick-installation structure for an electric vehicle controller provided in this application adopts the following technical solution: A conductive heat dissipation quick-release structure for an electric vehicle controller includes a flow guide column and a power supply component. The flow guide column is mounted on a circuit board, and multiple heat dissipation grooves are formed on the side wall of the flow guide column. The power-conducting component includes a power cord and a connecting post, wherein the connecting post is disposed at the end of the power cord; The guide column has an installation groove, and a clamping element is provided in the installation groove; the clamping element is used to clamp the connecting column.

[0007] By adopting the above technical solution, the multi-layer heat dissipation groove structure on the sidewall of the guide column significantly increases the heat dissipation surface area. This increased contact area with air effectively improves heat dissipation efficiency, solving the temperature rise problem caused by the limited heat dissipation area of ​​traditional smooth cylindrical guide columns. The power supply component employs a structural design that combines connecting columns and clamping parts, enabling quick plug-in installation of the power cord, replacing the traditional threaded connection method and effectively improving installation and maintenance efficiency.

[0008] Preferably, the heat dissipation groove is a U-shaped groove or a V-shaped groove.

[0009] By adopting the above technical solution and using a U-shaped or V-shaped groove design, the surface area of ​​the heat dissipation groove is further expanded within a limited space, the heat dissipation airflow path is optimized, and the heat dissipation effect is enhanced.

[0010] Preferably, the clamping member is vertically disposed in the mounting groove, the clamping member includes a clamping block, and a pushing member is disposed between the side wall of the clamping block and the side wall of the mounting groove, the pushing member being used to push the clamping block to clamp the connecting column.

[0011] By adopting the above technical solution, this solution automatically pushes the clamping block with the pusher to clamp and fix the connecting column, which simplifies the installation operation steps and improves the connection reliability.

[0012] Preferably, the pushing element is a pushing spring.

[0013] By adopting the above technical solution, a push spring is used as an elastic push element to provide a continuous and stable radial clamping force for the clamping block, ensuring good contact of the electrical connection.

[0014] Preferably, the clamping component further includes a sliding support rod, which is disposed on the side wall of the clamping block near the mounting groove. A sliding groove is provided on the side wall of the mounting groove, and the sliding support rod is disposed on the guide column through the sliding groove. The push spring is sleeved on the sliding support rod, with one end of the push spring abutting against the side wall of the mounting groove and the other end of the push spring abutting against the side wall of the clamping block.

[0015] By adopting the above technical solution, the sliding support rod provides precise guidance for the clamping block, ensuring that the clamping block moves in a straight line. The sleeve installation method of the push spring improves the stability of the spring's operation and prevents deflection.

[0016] Preferably, the connecting column is vertically arranged in the mounting groove, and the side wall of the connecting column is inclined from top to bottom towards the axis; the side wall of the clamping block facing the connecting column is set as an inclined surface that clamps and engages with the connecting column.

[0017] By adopting the above technical solution, the conical surface design of the connecting column and the inclined surface of the clamping block form a self-locking clamping structure, which can generate a larger clamping force when subjected to external force, thereby improving the connection stability.

[0018] Preferably, a limiting block is provided at the upper end of the clamping block, and the limiting block is used to limit the axial movement of the connecting column.

[0019] By adopting the above technical solution, the limiting block effectively prevents the connecting column from loosening or coming off under vibration by axially limiting the top of the connecting column.

[0020] Preferably, a conductive sheet is provided at the bottom of the mounting groove. The conductive sheet is an arched spring sheet, and the upper end of the conductive sheet abuts against the lower end of the connecting post.

[0021] By adopting the above technical solution, the arched spring not only provides a reliable electrical connection, but also generates an upward thrust, keeping the connecting post and the limiting block in close contact, further enhancing the stability of the connection.

[0022] In summary, this application includes the following beneficial technical effects: By incorporating multiple layers of heat dissipation grooves on the sidewall of the guide column, the heat dissipation surface area is significantly increased, thereby improving heat dissipation efficiency. Addressing the low installation efficiency of traditional threaded connections, this application employs a clamping component instead of threaded connections. Automatic clamping and fixation are achieved simply by inserting the connecting column, simplifying the installation process. The arched spring design ensures both reliable electrical connection and assists the limiting block in achieving axial fixation. The insulating layer on the push spring prevents current from generating heat through the spring, ensuring the long-term stability of the clamping force. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a conductive heat dissipation quick-installation structure for an electric vehicle controller, referring to... Figures 1-3 The device includes a flow guide column 1 and a power supply assembly 4. The flow guide column 1 is fixedly connected to the circuit board by screws. Multiple layers of heat dissipation grooves 11 are formed axially on the outer wall of the flow guide column 1. In this embodiment, the heat dissipation grooves 11 are U-shaped grooves 111 or V-shaped grooves 112. The power supply assembly 4 includes a power cord 41 and a connecting post 42, with the connecting post 42 fixedly connected to the end of the power cord 41. A mounting hole 16 is formed on the top wall of the flow guide column 1, with a diameter larger than that of the connecting post 42. A mounting groove 12 is formed inside the flow guide column 1, located below the mounting hole 16 and communicating with it. Four clamping members 2 are provided in the mounting groove 12, evenly arranged circumferentially along the axis of the flow guide column 1. The connecting post 42 is vertically positioned in the mounting groove 12, and the clamping members 2 are used to clamp the connecting post 42 within the mounting groove 12.

[0030] Reference Figure 1 , Figure 3 and Figure 4 In this embodiment, one clamping component 2 is used as an example. The clamping component 2 includes a clamping block 22, a sliding support rod 21, and a toggle rod 24. A sliding groove 15 is provided on the side wall of the mounting groove 12. The sliding support rod 21 is fixedly connected to the side wall of the clamping block 22 facing the mounting groove 12. The sliding support rod 21 is slidably connected to the guide column 1 through the sliding groove 15. A pushing component 3 is provided between the side wall of the mounting groove 12 and the side wall of the clamping block 22. In this embodiment, the pushing component 3 is a pushing spring. The pushing spring is sleeved on the sliding support rod 21. One end of the pushing spring abuts against the side wall of the mounting groove 12, and the other end of the pushing spring abuts against the side wall of the clamping block 22. The pushing spring is used to push the clamping block 22 toward the center of the mounting groove 12. An insulating layer is provided on the pushing spring. The purpose of this design is to prevent the current from passing through the spring and generating heat when energized, avoiding the spring from weakening or failing due to heat, thereby ensuring the long-term reliability of the entire clamping mechanism.

[0031] Reference Figure 3The connecting column 42 is an inclined column, and its sidewalls are tapered surfaces that gradually taper towards the axis from top to bottom. The clamping block 22 has an inclined surface on its sidewall facing the connecting column 42 that clamps with it. To achieve reliable axial positioning of the connecting column 42 and facilitate clamping, this embodiment features a specially designed upper structure for the clamping block 22. Specifically, a limiting block 23 is fixedly installed at the upper end of the clamping block 22. The horizontal extension length of the limiting block 23 is greater than the horizontal length of the clamping block 22 body, allowing the limiting block 23 to form a protruding limiting structure in the radial direction of the clamping block 22. When the connecting column 42 is inserted into the mounting groove 12 and clamped and fixed by the clamping blocks 22, the limiting block 23 is precisely located at the top of the connecting column 42. By interlocking the limiting block 23 with the upper structure of the connecting column 42, the axial displacement of the connecting column 42 or its dislodgement from the mounting groove 12 can be effectively prevented, thereby achieving axial limiting of the clamping block 22.

[0032] Reference Figure 3 The diameter of the circular hole formed by the four clamping parts 2 in their natural state is larger than the diameter of the lower end of the connecting column 42, but smaller than the diameter of the upper end of the connecting column 42. During installation, the lower end of the connecting column 42 is first aligned and inserted into the mounting hole 16. Then, pressure is applied axially downwards, and the conical surface of the connecting column 42 gradually pushes open the clamping block 22, causing the sliding support rod 21 to compress the push spring until the entire connecting column 42 enters the mounting groove 12. At this time, the push spring rebounds, driving the clamping block 22 to move radially inwards, using its inclined surface to clamp and fix the connecting column 42. At the same time, the limiting block 23 set at the upper end of the clamping block 22 is located just above the top of the connecting column 42, forming an axial limit to prevent the connecting column 42 from coming out.

[0033] Reference Figure 3 Multiple conductive sheets 13 are provided on the bottom of the mounting groove 12, and the multiple conductive sheets 13 are arranged circumferentially along the axis of the mounting groove 12. In this embodiment, the conductive sheet 13 is an arched spring sheet, and the upper end of the arched spring sheet abuts against the lower end of the connecting post 42.

[0034] The implementation principle of the conductive heat dissipation quick-release structure for an electric vehicle controller according to an embodiment of this application is as follows: The guide column 1 is fixed to the circuit board. The multi-layer heat dissipation grooves 11 on the outer wall of the guide column 1 expand the heat dissipation surface area and enhance the heat dissipation capacity. When the connecting column 42 of the power-conducting component 4 is inserted into the mounting groove 12 of the guide column 1, the conical surface of the connecting column 42 contacts the inclined surface of the clamping block 22, pushing the clamping block 22 to slide along the guide direction of the sliding support rod 21, thereby compressing the pushing member 3. When the connecting column 42 is fully inserted into the mounting groove 12, the pushing member 3 rebounds, driving the clamping block 22 to move inward, using the inclined surface to clamp and fix the connecting column 42. The arched spring pushes the connecting column 42 upward, thereby making the upper end of the connecting column 42 close to the lower end of the limiting block 23. The limiting block 23 achieves axial limiting to prevent loosening. The conductive sheet 13 contacts the lower end of the connecting column 42.

[0035] This application increases the heat dissipation area of ​​the guide column 1 by using the heat dissipation groove 11, which overcomes the problem of temperature rise caused by insufficient heat dissipation of the traditional smooth cylindrical guide column 1; at the same time, the clamping part 2 structure replaces the threaded connection, which simplifies the installation process, and the connecting column 42 can be directly inserted to complete the fixation, thereby improving the assembly and maintenance efficiency.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
