Description

Technical Field

[0001] This utility model relates to the field of power-off switch technology, and in particular to a waterproof encapsulation structure for a power-off switch for a four-wheeled vehicle. Background Technology

[0002] In existing technologies, the main function of power-off switches is power-off protection. Currently, the internal structure of power-off switches for four-wheeled electric vehicles on the market is relatively simple and has low reliability. They generally include a bracket and a limit switch installed inside the bracket. The encapsulation structure is usually achieved by covering the wire outlet of the assembled bracket with heat-shrink tubing to achieve waterproof and dustproof effects. However, this encapsulation method is time-consuming and cannot meet high waterproof and dustproof levels. Because there is a gap between the limit switch and the inner wall of the bracket, water can easily enter the inside under prolonged rain exposure, increasing the probability of water ingress into the power-off switch. Water entering the bracket and falling onto the wire solder joints of the power-off switch is detrimental to driving safety and can easily cause the power-off switch to malfunction. At the same time, most of the conductive wires inside the power-off switch are fixedly connected together, which requires complete disassembly and replacement when the circuit is damaged, which is quite troublesome.

[0003] Chinese utility model patent application number 202120942799.1 discloses a glue-filling encapsulation structure for an electric vehicle power-off switch, including a bracket and a limit switch disposed within the bracket. The bracket has a glue-filling port located on its outer wall, aligned with the solder joint of the limit switch's wires. The limit switch is covered with a waterproof rubber cap, which is a hat-shaped structure adapted to the push-button of the limit switch, including a brim and a central raised portion. The brim forms a sealing fit with the inner wall of the bracket, and the raised portion has a through hole for the push-button of the limit switch to pass through. However, this glue-filling encapsulation structure for an electric vehicle power-off switch uses a single-layer encapsulation structure, which has limited sealing. When the electric vehicle is exposed to rain for an extended period, water can still enter the power-off switch structure. Furthermore, its end portion lacks an installation structure, failing to meet the installation requirements of the power-off switch and hindering quick disassembly and maintenance of the encapsulation structure.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] A waterproof encapsulation structure for a power-off switch for a four-wheeled vehicle includes a micro switch 1, which is electrically connected to the electric control system of the four-wheeled vehicle. It also includes an encapsulation mechanism forming a double-layer encapsulation structure, a triggering mechanism forming a power-off switch triggering structure, and an installation mechanism to meet the installation requirements of the power-off switch. The encapsulation mechanism is located outside the micro switch 1, the triggering mechanism is configured inside one end of the encapsulation mechanism corresponding to the micro switch 1, and the installation mechanism is assembled at the end of the encapsulation mechanism. A schematic diagram of the overall structure of this utility model is shown below. Figure 1 As shown.

[0026] The encapsulation mechanism includes an encapsulation base shell 2 and an encapsulation sleeve shell 3. The encapsulation base shell 2 is disposed on the outside of the micro switch 1 and is fitted and connected to the micro switch 1. The connecting end of the micro switch 1 protrudes from one end of the encapsulation base shell 2. The encapsulation sleeve shell 3 is disposed on one end of the encapsulation base shell 2 and is fastened to the encapsulation base shell 2. The encapsulation mechanism, through the cooperation of the encapsulation base shell 2 and the encapsulation sleeve shell 3, forms a double-layer detachable encapsulation structure on the outside of the micro switch 1. The encapsulation base shell serves as the encapsulation structure on the outside of the micro switch 1 and provides mounting support for the encapsulation base shell 2. The encapsulation sleeve shell 3 is used to fasten to the encapsulation base shell 2 to form a double-layer detachable encapsulation structure on the outside of the micro switch 1. A schematic diagram of the encapsulation mechanism structure of this utility model is shown below. Figure 2 As shown.

[0027] It also includes a mounting end 4 and a connecting end 5. The mounting end 4 is located at the end of the encapsulation base shell 2 away from the encapsulation sleeve shell 3 and is integrally formed with the encapsulation base shell 2. The connecting end 5 is located at the end of the encapsulation sleeve shell 3 away from the encapsulation base shell 2 and is integrally formed with the encapsulation sleeve shell 3. The mounting end 4 serves as the mounting structure at the end of the encapsulation base shell 2 away from the encapsulation sleeve shell 3, and the connecting end 5 serves as the mounting structure at the end of the encapsulation sleeve shell 3 away from the encapsulation base shell 2. The mounting end 4 and the connecting end 5 together constitute the mounting structures at both ends of the encapsulation structure to meet the installation requirements of the power-off switch. A schematic diagram of the mounting end 4 and the encapsulation base shell 2 is shown below. Figure 3 As shown.

[0028] The device also includes mounting clips 6 and mounting slots 7. Two sets of mounting clips 6 are symmetrically arranged on both sides of the end of the encapsulation base shell 2 near the encapsulation sleeve shell 3 and integrally formed with the encapsulation base shell 2. Two sets of mounting slots 7 are also provided, corresponding to the two sets of mounting clips 6, symmetrically arranged on both sides of the end of the encapsulation sleeve shell 3 near the encapsulation base shell 2 and penetrating the encapsulation sleeve shell 3. The mounting clips 6 and mounting slots 7 engage, and the encapsulation sleeve shell 3 is connected to the encapsulation base shell 2 via the mounting clips 6 and mounting slots 7. The mounting clips 6 serve as a mounting structure on the encapsulation base shell 2, and the mounting slots 7 serve as a mounting structure on the encapsulation sleeve shell 3 to meet the engagement requirements of the mounting clips 6. The encapsulation base shell 2 and the encapsulation sleeve shell 3 are connected via the mounting clips 6 and mounting slots 7, which meets the needs of personnel for disassembling and repairing the encapsulation structure. Furthermore, when the encapsulation base shell 2 and the encapsulation sleeve shell 3 are engaged, the connecting ends partially overlap to form a double-layer encapsulation structure, effectively improving its waterproof effect. A cross-sectional view of the encapsulation mechanism of this utility model is shown below. Figure 4 As shown.

[0029] The encapsulation base shell 2 has a wedge-shaped limiting groove structure on one side near the encapsulation sleeve shell 3. Inside the encapsulation sleeve shell 3, a strip-shaped limiting block is provided corresponding to the wedge-shaped limiting groove structure. The inner side of the strip-shaped limiting block is provided with a cylindrical limiting ring corresponding to the trigger mechanism. The mounting end 4 and the connecting end 5 are provided with external threads. The wedge-shaped limiting groove structure is used as a limiting structure on the encapsulation base shell 2, and the strip-shaped limiting block is used as a limiting structure inside the encapsulation sleeve shell 3. When the encapsulation base shell 2 and the encapsulation sleeve shell 3 are installed and snapped together, there will be no deflection between the encapsulation base shell 2 and the encapsulation sleeve shell 3 under the action of the wedge-shaped limiting groove structure and the strip-shaped limiting block structure, so as to realize the quick and accurate installation and snapping operation of the encapsulation structure. The cylindrical limiting ring is used as a limiting structure inside the encapsulation sleeve shell 3, which can limit and guide the trigger mechanism, thereby avoiding the trigger mechanism from deviating and effectively improving the installation accuracy of the trigger mechanism.

[0030] The triggering mechanism includes a trigger rod 8 and a trigger end 9. The trigger rod 8 is disposed inside the encapsulation housing 3 and the connecting end 5 and is inserted into the encapsulation housing 3 and the connecting end 5. The trigger end 9 is disposed at the end of the trigger rod 8 near the encapsulation housing 3 and is integrally formed with the trigger rod 8. The trigger end 9 is located inside the cylindrical limiting ring at the end near the micro switch 1. The triggering mechanism, through the cooperation of the trigger rod 8 and the trigger end 9, constitutes the triggering structure in the power-off switch to realize the change of the on / off state of the electric four-wheeled vehicle. 8 is used to form the trigger structure in the power-off switch. The trigger end 9, together with the trigger rod 8, forms the trigger structure in the power-off switch. In the working state, the end of the trigger rod 8 away from the trigger end 9 protrudes from the connecting end 5. The trigger end 9 is in contact with the switching end of the micro switch 1. When it is necessary to disconnect the power to the electric four-wheeled vehicle, press the end of the trigger rod 8 protruding from the connecting end 5, so that it drives the trigger end 9 to press the switching end of the micro switch 1, thereby disconnecting the power to the electric four-wheeled vehicle. The overall structural cross-sectional view of the power-off switch of this utility model is shown below. Figure 5 As shown.

[0031] The mounting mechanism includes mounting nuts 10 and mounting caps 11. There are two sets of mounting nuts 10, which are arranged side by side adjacent to each other at the end of the connecting end 5 near the encapsulation housing 3 and are threadedly connected to the connecting end 5. The mounting caps 11 are located on the outside of the mounting end 4 and are threadedly connected to the mounting end 4. The mounting mechanism, through the cooperation of mounting nuts 10 and mounting caps 11, forms the mounting structure of the end of the power-off switch to meet the installation requirements of the power-off switch. The mounting nuts 10 are used as the mounting structure on the connecting end 5, and the mounting caps 11 are used as the mounting structure on the mounting end 4.

[0032] The mounting cap 11 has a conical cap-shaped structure and an anti-slip stripe structure on its outer side. The mounting end 4, away from the encapsulation base shell 2, has a wire passage opening. The mounting cap 11 is assembled on the outer side of the mounting end 4 and the wire passage opening. The wire end of the micro switch 1 protrudes from the end of the mounting cap 11 away from the encapsulation base shell 2, and the trigger rod 8 protrudes from the end of the connecting end 5 away from the encapsulation shell 3. The anti-slip stripe structure is used as an anti-slip structure on the mounting cap 11 to improve the anti-slip effect of the mounting cap 11. The wire passage opening is used to meet the wire passage requirements of the micro switch 1's wire end. By rotating the conical cap-shaped mounting cap 11, the tightness of the wire passage opening can be adjusted, thereby adjusting the assembly accuracy and stability of the micro switch 1's wire end.

[0033] Among them, the micro switch 1 can be an electronic micro switch 1 from the existing technology.

[0034] Working principle:

[0035] During assembly, place the micro switch 1 inside the encapsulation base shell 2 with its connecting end protruding beyond the mounting end 4. Assemble the trigger mechanism inside the encapsulation sleeve 3 with its end away from the trigger end 9 protruding beyond the connecting end 5. Then, connect the encapsulation sleeve 3 and the encapsulation base shell 2 together using the mounting buckle 6 and the mounting slot 7. Assemble the mounting nut 10 onto the connecting end 5. Finally, assemble the mounting cap 11 onto the mounting end 4. This completes the assembly of the encapsulation mechanism. When it is necessary to disconnect the power to the electric four-wheeled vehicle, press the end of the trigger rod 8 that protrudes beyond the connecting end 5, causing it to drive the trigger end 9 to press the switching end of the micro switch 1, thereby disconnecting the power to the electric four-wheeled vehicle.

[0036] The advantages of this utility model are its simple structure, with a double-layer encapsulation structure formed by the cooperation of the encapsulation mechanism and the triggering mechanism, which can effectively improve the sealing effect of the power-off switch and prevent water from entering the power-off switch structure when the electric vehicle is exposed to rain for a long time. In addition, its encapsulation mechanism adopts a snap-fit ​​installation method for assembly and connection, which is convenient for workers to disassemble and repair. It is equipped with an installation mechanism to meet the installation requirements of the power-off switch terminal and has strong installation stability.

[0037] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
