Description

Technical Field

[0001] This utility model relates to the field of switch devices, and in particular to a rotatable automotive power-off switch. Background Technology

[0002] A battery switch, as a switch structure connected to the battery terminal (usually the negative terminal), cuts off the power supply to the entire circuit when the switch is turned off, effectively preventing battery leakage and self-discharge. It is particularly widely used in trucks.

[0003] Most commonly used switches are rotary or lever switches. Rotary switches are usually connected to the negative terminal of the car battery, while lever switches are generally installed on the vehicle's ground bus. Common rotary switches have a connection hole for connecting to the terminal, allowing the switch to be directly fitted onto the battery's negative terminal. However, because truck batteries are mounted on the chassis, and the space above is often limited by the cargo box or cab, connecting the rotary switch's connection hole to the battery terminal is inconvenient due to the limited space, making it difficult to install a power disconnect switch. Summary of the Invention

[0004] The main objective of this invention is to provide a rotatable automotive power-off switch, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rotatable automotive power cut-off switch, comprising:

[0007] case;

[0008] Two conductive plates are symmetrically mounted on the housing, with one of the conductive plates extending from inside the housing to the outside.

[0009] The end of the conductive sheet that extends to the outside is connected to a clip for connecting to the battery terminal;

[0010] The handle is movably mounted on the housing;

[0011] A movable conductive plate, installed at the bottom of the handle, is used to connect / disconnect the two conductive plates.

[0012] Furthermore, it also includes:

[0013] The spring has its bottom resting against the bottom of the inner cavity of the housing, and its top contacting the movable conductive plate, providing an upward elastic force to the movable conductive plate.

[0014] Furthermore, the movable conductive sheet has a plug hole, and a support column matching the sliding hole is fixedly installed at one end of the handle located inside the housing.

[0015] Furthermore, a conductive electrode post is fixedly installed on the housing, and the conductive electrode post is in contact with another conductive sheet.

[0016] Furthermore, a pin is fixedly installed on the handle, and an annular concave-convex ring is fixedly installed on the inner side wall of the housing. The pin contacts the concave-convex ring, and when the handle is rotated, the pin contacts the concave-convex ring at different positions to change the position of the movable conductive sheet.

[0017] Furthermore, a convex ring is fixedly installed inside the housing, and the bottom of the spring is located in the convex ring to limit the spring.

[0018] Furthermore, a limiting part is provided inside the housing to limit the movement of the movable conductive sheet, so that the movable conductive sheet can only move up and down.

[0019] Furthermore, the conductive sheet located inside the casing has a downward-bent structure.

[0020] Furthermore, the bottom of the housing is open, and a base plate is bolted to the opening.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention features a conductive sheet extending to the outside, with a clip fixedly connected to the conductive sheet for connection to the car battery terminal. When installing the rotary switch, the clip is directly connected to the negative terminal of the car battery, eliminating the need to wrap the entire switch around the negative terminal, making it more suitable for operation in confined spaces.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-8 As shown, this embodiment provides a rotatable automotive power-off switch, including:

[0037] The housing 1 and the base plate 11 together form the housing structure of the switch. The housing 1 has an open bottom, and the base plate 11 is detachably installed together with the housing 1 using bolts.

[0038] A first conductive sheet 4 and a second conductive sheet 6 are mounted on the housing 1. The first conductive sheet 4 is fixedly mounted on the housing 1 with bolts, and extends outward from the housing 1, penetrating the housing and reaching the outside. A clip 5 is mounted on the outer end of the first conductive sheet 4 with bolts. Figures 1-7As shown. Clip 5 is used to connect to the battery terminal. Clip 5 is designed with a U-shaped structure, forming a circle with a side opening inside for engaging with the battery terminal. A bolt is rotatably installed at the opening. Rotating the bolt moves the opening closer or further away, clamping or loosening the battery terminal. This allows for direct connection to the battery terminal, making it more convenient when the space above the battery is limited, especially suitable for large trucks. Since the starter battery of large trucks is usually placed on a battery rack on the front or side of the vehicle, and the battery rack is generally fixed to the vehicle frame, with the cargo box or front end located above the battery rack, the space above the battery is relatively small due to the obstruction. Directly connecting the switch to the battery terminal would be inconvenient. Therefore, by setting exposed conductive plates and clips, the installation of the power disconnect switch is facilitated.

[0039] In this embodiment, the clip 5 can rotate around the bolt. That is, when connecting the first conductive plate 4 and the clip 5 using the stud and nut, the nut does not need to be tightened while ensuring that the clip 5 is in contact with the first conductive plate 4. The relative position between the clip 5 and the housing 1 can be adjusted or changed, such as... Figures 1-4 As shown, the clip 5 and the first conductive piece 4 are on the same straight line, and the clip 5 can also be rotated, as shown in the details. Figure 5 As shown (clip 5 is perpendicular to the first conductive piece 4), clip 5 can rotate around the bolt to adjust its relative position, making installation easier. For narrow or short spaces, the rotation of clip 5 reduces the length between clip 5 and housing 1, making it suitable for use in such spaces. After adjusting the position of clip 5, the nut can be tightened to clamp or secure clip 5 using the nut and stud, preventing it from shaking while the vehicle is in motion.

[0040] Conductive electrode posts 2 are fixedly installed on the housing 1, as shown in the following figure. Figure 3 , Figures 5-7 As shown, the housing 1 has a mounting hole, and the bottom of the conductive electrode post 2 has a threaded hole. The conductive electrode post 2 is fixed to the housing 1 with bolts from the opening of the housing 1. At the same time, the bolts fix the second conductive plate 6 to the housing 1. The bottom of the conductive electrode post 2 contacts the second conductive plate 6, so that power can be conducted to the conductive electrode post 2. The conductive electrode post 2 can be connected to the external wiring of the car.

[0041] The handle 3 is rotatably mounted on the housing 1, with one end of the handle 3 extending into the inner cavity of the housing 1. The first conductive plate 4 and the second conductive plate 6 are symmetrically arranged about the handle 3. A movable conductive plate 10 is mounted on one end of the handle 3 located on the housing 1. Figure 4 and Figure 5As shown, the movable conductive sheet 10 has a insertion hole, and a support column is fixedly installed at one end of the handle 3's column. The support column is inserted into the insertion hole and can rotate and slide up and down within the insertion hole. The diameters of the support column and the insertion hole are smaller than the diameter of the handle 3's column, so that the movable conductive sheet 10 can contact the handle 3's column. When the handle 3 moves downward, it can carry the movable conductive sheet 10 downward. A corresponding limiting part is also provided in the housing 1, such as... Figure 3 As shown, the limiting part is a sliding groove 12 opened on the housing 1. The movable conductive sheet 10 is located in the sliding groove 12 and can move up and down in the sliding groove 12. The sliding groove 12 limits the movable conductive sheet 10 to prevent the movable conductive sheet 10 from rotating with the handle 3.

[0042] A concave-convex ring 9 is fixedly installed at the contact point between the housing 1 and the handle 3, such as... Figure 8 As shown. The design of the concave-convex ring 9 is the same as that of rotary switches in the prior art, and will not be described in detail here.

[0043] 0042 Spring 7, the bottom of spring 7 abuts against the base plate 11, and the top abuts against the movable conductive sheet 10, as shown. Figure 5 As shown, spring 7 provides an upward elastic force to the movable conductive sheet 10. A convex ring is fixedly installed on the upper side of the base plate 11, and the bottom of spring 7 is located in the convex ring. The convex ring limits the movement of spring 7 to prevent it from shifting.

[0044] A pin is fixedly installed on the handle 3. Under the action of the spring force 7, the pin contacts the concave and convex ring 9. When the handle 3 is rotated, it can move up and down in contact with the concave and convex ring 9 and contact different positions of the concave and convex ring 9, changing the position of the movable conductive sheet 10, so as to realize the connection and / or disconnection between the first conductive sheet 4 and the second conductive sheet 6.

[0045] In this embodiment, the extension and retraction of the spring 7 is greater than the vertical movement distance of the handle 3, ensuring that the spring 7 always provides an upward elastic force to the movable conductive plate 10 and the handle 3. Furthermore, when the handle 3 moves upward to its highest point, the bottom of the handle 3's upright is located above the plane containing the bottom surfaces of the first conductive plate 4 and the second conductive plate 6. In this state, since the movable conductive plate 10 can slide on the support column, the elastic force of the spring 7 ensures that the conductive plate 10 is in contact with the first conductive plate 4 and the second conductive plate 6, maintaining circuit continuity and preventing poor contact.

[0046] In a further embodiment, such as Figure 10 and Figure 11 As shown, bolts pass through the bottom plate 11 from the bottom and connect the bottom plate to the housing 1. The second conductive sheet 6 is configured with a downwardly bent structure, as shown... Figure 11As shown, a low end and a high end are formed. The high end is on the same plane as the first conductive plate 4 and can contact the movable conductive plate 10. The low end is located at the end away from the movable conductive plate 10, and its height is lower than that of the high end. This design can reduce the thickness of the housing at the position of the second conductive plate 6. For the narrow space where the battery is installed, the overall height of the conductive electrode post 2 and the housing is smaller, and the space occupied is smaller. In the same space, there is more space reserved for wiring when connecting wires, which is more suitable for use in narrow spaces.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
