Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of motor controller anti-accidental touch structure, and in particular to an anti-accidental touch structure for a motor controller for electric vehicles. Background Technology
[0002] The electric vehicle motor controller is the core component of the electric vehicle power system. It is responsible for converting the DC power from the battery into the three-phase AC power required by the motor, and for precisely controlling the motor's torque, speed, and direction. There are various types of electric vehicle motor controllers. Among them, electric vehicle motor controllers need to have an anti-accidental touch structure on their surface to prevent accidental touch of the knobs from causing misoperation of the vehicle.
[0003] Existing anti-accidental touch structures typically cannot protect motor controller knobs and buttons. In the event of a collision, the controller's operating components may be damaged. Furthermore, there is no clamping structure for knobs and other components. When the electric vehicle is in motion, vibrations may cause the knobs to rotate slightly, which could affect the normal operation of the motor controller and make it difficult to operate. Utility Model Content
[0004] In view of the problems existing in the above-mentioned anti-accidental touch structure of motor controller for electric vehicles, this utility model is proposed.
[0005] Therefore, the problem that this utility model aims to solve is that the anti-accidental touch structure in the prior art usually cannot protect the knobs and buttons of the motor controller. When encountering a collision, it may cause damage to the controller operating parts. At the same time, it does not have a clamping structure for the knobs and other parts. When the electric vehicle is in motion, the knob parts may rotate slightly due to vibration.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a structure for preventing accidental touch of a motor controller for an electric vehicle, comprising a housing assembly, the housing assembly comprising a housing body, a cover plate assembly comprising a cover plate body installed on the top of the housing body, and track assemblies fixedly installed on both the front and rear sides of the inner cavity of the housing body, the track assemblies comprising track bodies fixedly installed on the top of the front and rear sides of the inner cavity of the housing body, a limit assembly comprising a T-shaped block disposed in the inner cavity of the track body, a bolt threadedly connected to the top of the T-shaped block, a sleeve fixedly connected to one side of the T-shaped block, a fixing plate disposed inside the sleeve, a spring fixedly connected to the other side of the fixing plate, and a clamping plate fixedly installed on the other side of the spring.
[0007] As a preferred embodiment of the anti-accidental touch structure for the electric vehicle motor controller of this utility model, the four corners of the bottom of the inner cavity of the outer shell are fixedly connected to mounting plates, the surface of the mounting plates is provided with mounting holes, and the mounting plates are integrated with the outer shell.
[0008] As a preferred embodiment of the anti-accidental touch structure for the electric vehicle motor controller of this utility model, the main body of the outer shell is provided with sliding grooves on both the front and rear sides, and the main body of the cover plate is fixedly connected with sliding plates on both the front and rear sides of the inner cavity. The sliding plates extend into the inner cavity of the sliding grooves and make sliding contact with their inner walls.
[0009] As a preferred embodiment of the anti-accidental touch structure for the electric vehicle motor controller of this utility model, a push-pull groove is provided on the right side of the top of the cover plate body, a magnetic structure is provided on the right side of the inner cavity of the cover plate body, and a magnetic suction plate is inlaid on the top of the right side of the outer shell body.
[0010] As a preferred embodiment of the anti-accidental touch structure for the electric vehicle motor controller of this utility model, the interior of the track body is a T-shaped structure, the top of the track body is provided with a through hole for a bolt to move, and the right side of the top of the track body is provided with a notch for a T-shaped block to be inserted.
[0011] As a preferred embodiment of the anti-accidental touch structure for the electric vehicle motor controller of this utility model, a rectangular column is provided on the back of the fixing plate, the surface of the column is in contact with the inner wall of the housing, and a bolt is threaded onto one end of the top of the housing, the bottom of the bolt penetrates into the inner cavity of the housing and abuts against the surface of the column.
[0012] As a preferred embodiment of the anti-accidental touch structure for the electric vehicle motor controller of this utility model, the side of the clamping plate away from the spring is set with an arc-shaped structure, and the arc-shaped surface of the clamping plate is provided with several anti-slip grooves.
[0013] The beneficial effects of this utility model are:
[0014] 1. The outer shell surrounds the controller's operating components, and the magnetic knot on the cover plate adheres to the surface of the magnetic plate for sealing. This provides dust and collision protection for the controller when no one is around, greatly improving the protection of the controller's operating components. Moreover, it is very convenient to use; simply remove the cover plate to operate the controller.
[0015] 2. The controller knob is clamped by a clamping plate. The elasticity of the spring increases the friction of the knob rotation, thereby preventing the knob from rotating slightly under vibration and effectively ensuring the stability of the controller knob.
[0016] 3. The device can add a corresponding number of clamping components inside the track body as needed, which can clamp different numbers of knob parts. The clamping components can be adjusted at will inside the track body through T-blocks, which can clamp and fix knob parts in different positions, greatly improving the applicability of the device and making it suitable for different types of motor controllers.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] Reference Figures 1-7 An anti-accidental-touch structure for a motor controller for an electric vehicle includes a housing assembly 1. The housing assembly 1 includes a housing body 101. A cover plate assembly 2 is provided on the top of the housing body 101. The cover plate assembly 2 includes a cover plate body 201, which is installed on the top of the housing body 101. Track assemblies 4 are fixedly installed on both the front and rear sides of the inner cavity of the housing body 101. The track assembly 4 includes a track body 401, which is fixedly installed on the top of the front and rear sides of the inner cavity of the housing body 101. A limit assembly 3 is provided inside the track body 401. The limit assembly 3 includes a T-block 301, which is located in the inner cavity of the track body 401. A bolt 302 is threadedly connected to the top of the T-block 301. A sleeve 303 is fixedly connected to one side of the T-block 301. A fixing plate 305 is provided inside the sleeve 303. A spring 306 is fixedly connected to the other side of the fixing plate 305. A clamping plate 307 is fixedly installed on the other side of the spring 306.
[0029] It should be noted that mounting plates 102 are fixedly connected to the four corners of the bottom of the inner cavity of the outer shell 101. Mounting holes are opened through the surface of the mounting plates 102. The mounting plates 102 and the outer shell 101 are designed as an integral piece. The mounting plates 102 at the four corners provide both screw fixing and adhesive fixing options (M4 screw fixing is recommended).
[0030] It should be noted that the front and rear sides of the outer shell body 101 are provided with sliding grooves 103, and the front and rear sides of the inner cavity of the cover body 201 are fixedly connected with sliding plates 203. The sliding plates 203 extend into the inner cavity of the sliding grooves 103 and slide in contact with their inner walls. The sliding cooperation between the sliding plates 203 and the sliding grooves 103 enables the cover body 201 to be quickly disassembled and assembled.
[0031] It should be noted that a push-pull groove 202 is provided on the right side of the top of the cover body 201, the right side of the inner cavity of the cover body 201 is set with a magnetic structure, and a magnetic suction plate 104 is inlaid and installed on the top right side of the outer shell body 101.
[0032] Specifically, the magnetic force between the magnetic plate 104 and the magnetic structure is greater than or equal to 8N, ensuring that the cover plate closes securely.
[0033] It should be noted that the interior of the track body 401 is a T-shaped structure. The top of the track body 401 has a through hole 402 for the bolt 302 to move, and the right side of the top of the track body 401 has a notch 403 for the T-shaped block 301 to be inserted.
[0034] Furthermore, the sliding fit structure of T-block 301 and track body 401 is adopted, and the limiting component 3 can be freely added or removed according to the number of knobs. The through hole 402 and notch 403 are designed to make the component position adjustable and adapt to the layout of knobs with different spacing.
[0035] It should be noted that a rectangular column is provided on the back of the fixing plate 305. The surface of the column is in contact with the inner wall of the casing 303. A bolt 2 304 is threaded on one end of the top of the casing 303. The bottom of the bolt 2 304 penetrates into the inner cavity of the casing 303 and abuts against the surface of the column.
[0036] Furthermore, bolt 304 achieves double fixation by pressing the rectangular column to prevent spring 306 from rebounding and loosening;
[0037] It should be noted that the side of the clamping plate 307 away from the spring 306 is designed with an arc shape. The pre-compression design of the spring 306 (adjustable compression amount) enables the clamping plate 307 to generate a continuous clamping force. Furthermore, the arc-shaped surface of the clamping plate 307 is provided with several anti-slip grooves. The anti-slip grooves enhance the friction coefficient of the surface of the clamping plate 307 (actual measurement shows that it can improve the anti-slip effect by 40%).
[0038] Furthermore, the arc-shaped structure of the clamping plate 307 matches the standard knob diameter (Φ15-25mm), and the stiffness coefficient of the spring 306 is selected in the range of 8-12N / mm.
[0039] In use, place the outer casing 101 above the motor controller control components, use the mounting plate 102 to position the installation, and place screws on its surface through the mounting holes to install it onto the surface of the electrical controller (or use non-adhesive for direct adhesion). After installation, observe the number of knob-like components, then select the corresponding number of limit components 3, and slide them sequentially into the interior of the track body 401 through the notch 403. Then, slide the limit components 3 sequentially through the T-block 301 to the knob-like components, and then tighten the bolt 302. Use the cap on the top of the bolt 302 to press against the top of the track body 401, thereby securing the T-block 301. First, fix the knob, then pull the fixing plate 305 out from inside the housing 303, causing it to move the spring 306 and the clamping plate 307 until the clamping plate 307 is pressed against the knob. Then, compress the spring 306 (the compression force can be set according to the requirements), and then tighten the bolt 304 to press it against the rectangular post on the fixing plate 305, thereby fixing the fixing plate 305. The elasticity of the spring 306 drives the clamping plate 307 to elastically clamp the knob, increasing the friction of the knob rotation and preventing micro-rotation due to vibration. Laboratory tests show that it can reduce the accidental touch rate by more than 98% without affecting the normal knob operating torque (operating torque increases by <15%).
[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
