A car battery switch Technical Field

[0001] This utility model relates to the field of current switches, and more particularly to an automotive battery switch. Background Technology

[0002] As the core power supply unit of the vehicle's electrical system, the reliable connection and status monitoring of the vehicle battery directly affect the vehicle's starting stability and the operational safety of electronic equipment. In the existing technology, the current conduction between the battery and the vehicle generally relies on physical clamping, that is, the circuit connection is achieved by fixing the battery's positive and negative terminals with metal clips respectively.

[0003] However, the above connection scheme has two major drawbacks: First, when it is necessary to disconnect or reconnect the battery (such as disconnecting the battery from the vehicle to extend its lifespan), the user must manually open the engine hood and perform close-range operations, which is inconvenient for users without vehicle maintenance experience; Second, the user cannot monitor the battery's health in real time. If the battery is not maintained for a long time, it is prone to aging, insufficient current, or depletion, which can prevent the vehicle from starting normally. Summary of the Invention

[0004] The purpose of this utility model is to provide a car battery switch. This device is installed inside the car compartment, which makes it convenient for users to open and close the electrical connection between the battery and the vehicle's electrical system. The battery's operating status is also displayed on the display screen on the device.

[0005] The technical solution adopted by the automobile battery switch disclosed in this utility model is:

[0006] The device includes a knob, a central axis, and a base. The knob has a through slot and a circuit board with a display screen. One end of the central axis is fixedly connected to the knob, and a spring is sleeved on the outside of the central axis. A guide plate is axially slidably connected to the central axis, with the spring contacting the guide plate. The knob is rotatably connected to the base. The other end of the central axis passes through the base, and the guide plate is located inside the base. A connecting post extends from the base and passes through the through slot, being fixedly connected to the circuit board. A data cable is provided on the base, with one end passing through the through slot and electrically connected to the circuit board. Two non-contacting conductive components are located inside the base, and the two ends of the guide plate respectively contact the two conductive components. The conductive components protrude from the base.

[0007] As a preferred embodiment, the base is provided with a connecting seat, the conductive component is fixedly connected to the connecting seat, the other end of the central shaft touches the connecting seat, and the guide plate is located above the connecting seat.

[0008] As a preferred embodiment, two contact plates are fixedly connected to the top of the connector, with the two contact plates respectively close to two conductive components.

[0009] As a preferred embodiment, the base is composed of a shell and a base plate, the top of the connecting seat is fixedly connected to the inside of the shell, the base plate touches the bottom of the connecting seat, and the connecting post is located at the top of the shell.

[0010] As a preferred embodiment, the top of the housing has a through hole, through which one end of the data cable passes.

[0011] As a preferred embodiment, a limiting member is axially slidably connected on the central shaft, and the two ends of the spring respectively abut against the limiting member and the guide plate. Two protrusions extend into the interior of the outer shell, one of which is located above one of the conductive components. A groove is provided on the limiting member, and one of the protrusions is inserted into the groove.

[0012] As a preferred embodiment, a retaining ring is snapped onto the outer side of the central shaft, and the retaining ring is located between the limiting member and the guide plate.

[0013] As a preferred embodiment, the knob is composed of a first housing and a second housing, the through groove passes through the first housing, one end of the central shaft is fixedly connected to the bottom of the first housing, the bottom of the first housing is rotatably connected to the top of the outer housing, the circuit board is placed between the first housing and the second housing, the second housing has a through slot, the display screen faces into the slot, and a light-transmitting plate is provided on the slot.

[0014] As a preferred embodiment, a connecting ring extends from the top of the outer shell, and an annular connecting groove is formed at the bottom of the first shell, wherein the connecting ring is engaged in the connecting groove for sliding contact.

[0015] The beneficial effects of the car battery switch disclosed in this utility model are:

[0016] The positive terminal of the battery is electrically connected to one of the conductive components via a power cable, and the vehicle electrical system is electrically connected to the other conductive component via a power cable. This device is installed inside the vehicle compartment. When the vehicle is started, the user rotates a knob to rotate the central shaft and guide plate, causing them to rotate and move above the conductive components. At the same time, the guide plate slides axially on the central shaft under the push of a spring, approaching the conductive components. This allows both ends of the guide plate to make electrical contact with the two conductive components, forming a complete current path to power the vehicle electrical system. After the vehicle stops, the user rotates the knob in the opposite direction to disconnect the guide plate from the two conductive components, cutting off the electrical connection between the battery and the vehicle electrical system. This allows the user to easily control the power supply between the battery and the vehicle electrical system, eliminates standby current, and extends battery life.

[0017] The vehicle electrical system is electrically connected to the data cable. When the battery is connected to the vehicle electrical system, the system can monitor the battery's operating status in real time and input the monitoring data into the circuit board for signal processing via the data cable. Finally, a visual parameter interface is generated on the display screen, allowing users to accurately assess the current health status of the battery and formulate maintenance strategies.

[0026] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0027] Please refer to Figures 1-4.

[0028] The present invention discloses a car battery switch, including a knob 1, a central shaft 2 and a base 3.

[0029] In this embodiment, the knob 1 is preferably composed of a first housing 11 and a second housing 12 combined, forming a space inside the first housing 11 and the second housing 12. The knob 1 is provided with a circuit board 13, and the circuit board 13 is provided with a display screen 131. The circuit board 13 is placed in the space between the first housing 11 and the second housing 12. A slot is passed through the second housing 12, and the display screen 131 faces into the slot. A light-transmitting plate 121 is provided on the top cover of the slot, and the user can view the parameter interface displayed on the display screen 131 through the light-transmitting plate 121.

[0030] Furthermore, a through groove 111 is provided on the knob 1. In this embodiment, it is preferred that there are two through grooves 111. The through grooves 111 penetrate through the first housing 11. An annular connecting groove is provided at the bottom of the first housing 11.

[0031] Please refer to Figures 3-8.

[0032] In this embodiment, the cross-section of the central shaft 2 is preferably quadrilateral, and the bottom of the first housing 11 is provided with a mounting groove. In this embodiment, the inner wall of the mounting groove is preferably quadrilateral. One end of the central shaft 2 is inserted into the mounting groove at the bottom of the first housing 11 for fixed connection, so that when the knob 1 is turned, the first housing 11 can drive the central shaft 2 to rotate synchronously.

[0033] The knob 1 is rotatably connected to the base 3. In this embodiment, the base 3 is preferably composed of a shell 31 and a base plate 32, forming a space inside the shell 31 and the base plate 32. The bottom of the first shell 11 is rotatably connected to the top of the shell 31.

[0034] Furthermore, a connecting ring 311 extends from the top of the outer shell 31. The connecting ring 311 slides into the connecting groove, and the center of the connecting ring 311 is on the same axis as the axis of the central shaft 2. A connecting post 312 extends from the base 3. In this embodiment, it is preferable to have two connecting posts 312. Both connecting posts 312 are located at the top of the outer shell 31. The connecting posts 312 pass through the through groove 111 and are fixedly connected to the circuit board 13, thereby fixing the circuit board 13 in the space between the first shell 11 and the second shell 12. When the knob 1 is rotated, the circuit board 13 will not rotate with the knob 1, thereby keeping the display screen 131 horizontal to display the parameter interface.

[0035] Furthermore, a data cable 33 is provided on the base 3, and a through hole is provided on the top of the housing 31. One end of the data cable 33 passes through the through hole and one of the through slots 111 in sequence and is electrically connected to the circuit board 13. The other end of the data cable 33 is electrically connected to the vehicle electrical system.

[0036] The other end of the central shaft 2 passes through the outer shell 31 and thus enters the base 3. A limiting member 21 and a guide plate 22 are axially slidably connected on the central shaft 2. Both the limiting member 21 and the guide plate 22 are located inside the outer shell 31 of the base 3. Both the limiting member 21 and the guide plate 22 are provided with mounting holes. The outline of the mounting holes is quadrilateral. The limiting member 21 is axially slidably connected to the central shaft 2 through the mounting holes, and the guide plate 22 is axially slidably connected to the central shaft 2 through the mounting holes, so that the central shaft 2 can drive the limiting member 21 and the guide plate 22 to rotate synchronously. The limiting member 21 and the guide plate 22 can slide axially a certain distance on the central shaft 2.

[0037] Furthermore, the limiting member 21 abuts against the inner wall of the outer shell 31, and a retaining spring 23 is engaged on the outer side of the central shaft 2. The retaining spring 23 is located between the limiting member 21 and the guide plate 22. There is a certain amount of movement between the retaining spring 23 and the limiting member 21. This prevents the central shaft 2 from detaching from the base 3, while allowing the limiting member 21 to slide axially a certain distance on the central shaft 2 before being constrained by the retaining spring 23. A spring 24 is sleeved on the outer side of the central shaft 2. The two ends of the spring 24 abut against the limiting member 21 and the guide plate 22, respectively. The spring 24 pushes the limiting member 21 to abut against the inner wall of the outer shell 31, and pushes the guide plate 22 away from the limiting member 21.

[0038] Furthermore, two protrusions 313 extend from the inner wall of the outer shell 31, forming a 90° right angle between the two protrusions 313 with the central axis 2 as the vertex. The cross-section of the protrusion 313 is arc-shaped, and a groove 211 is provided on the limiting member 21, in which one of the protrusions 313 is inserted into the groove 211.

[0039] When knob 1 performs a 90° rotation, knob 1 drives the limiting member 21 to rotate synchronously through the central axis 2. One of the protrusions 313 drives the limiting member 21 to generate axial displacement along the central axis 2 and compresses the spring 24 to store energy, completing the decoupling of the current protrusion 313 from the groove 211. The limiting member 21 slides back to its original position under the push of the spring 24. During continuous rotation, the other protrusion 313 is inserted into the groove 211 to form an interlock, thereby achieving the effect of knob 1 rotating to position the rotation angle and constructing a segmented positioning mechanism with clear tactile feedback signals.

[0040] The base 3 has a connecting seat 34 inside, which is placed in the space formed by the outer shell 31 and the bottom plate 32. Multiple mounting posts extend inside the outer shell 31. The top of the connecting seat 34 is fixedly connected to the mounting posts inside the outer shell 31. The multiple mounting posts surround the outer side of the guide plate 22. The bottom plate 32 touches the bottom of the connecting seat 34 and the bottom plate 32 constrains the connecting seat 34 inside the outer shell 31. The spring 24 pushes the guide plate 22 to slide axially a certain distance on the central shaft 2 and then touches the top of the connecting seat 34. The other end of the central shaft 2 touches the connecting seat 34.

[0041] Furthermore, the base 3 is provided with two non-contacting conductive components 35, which are fixedly connected to the connecting seat 34, and one of the protrusions 313 is located above one of the conductive components 35.

[0042] Furthermore, the conductive component 35 includes a metal sheet 351 and a bolt 352. The metal sheet 351 is placed at the bottom of the connector 34, and the bolt 352 is located at the top of the connector 34. The bolt 352 passes through the connector 34 and the metal sheet 351 in sequence. A nut 353 is connected to the bolt 352 to fix the metal sheet 351 to the connector 34. The metal sheet 351 protrudes from the outer casing 31. The top of the bolt 352 is flush with the top of the connector 34. The positive terminal of the battery is electrically connected to one of the metal sheets 351 through a power line, and the vehicle electrical system is electrically connected to the other metal sheet 351 through a power line. Rotating the knob 1 drives the limiting member 21 and the guide plate 22 to rotate synchronously through the central shaft 2, so that one of the protrusions 313 is inserted into the groove 211. The two ends of the guide plate 22 contact the two bolts 352 respectively and conduct current. Under the push of the spring 24, the guide plate 22 can fit more firmly with the bolts 352.

[0043] Furthermore, two contact pieces 341 are fixedly connected to the top of the connector 34. The two contact pieces 341 are respectively close to the bolts 352 of the two conductive components 35. The contact pieces 341 and the bolts 352 do not contact each other. In this embodiment, the contact pieces 341 are preferably made of metal. The top of the contact pieces 341 is flush with the top of the connector 34. Rotating the knob 1 drives the limiting member 21 and the guide piece 22 to rotate synchronously through the central shaft 2, so that another protrusion 313 is inserted into the groove 211. The two ends of the guide piece 22 contact the two contact pieces 341 respectively. In order to reduce the production cost of this device, the connector is made of engineering plastic injection molding. The contact pieces serve as an isolation barrier between the guide piece and the connector. Through physical isolation design, the direct contact between the guide piece and the connector is blocked, which effectively avoids the generation of plastic debris under long-term friction conditions and prevents the possible micro-debris from migrating to the electrical contact interface between the guide piece and the bolt, thereby avoiding affecting the conduction current of the guide piece.

[0044] Please refer to Figures 1-8.

[0045] When the user needs to start the vehicle:

[0046] Rotating knob 1 by 90° causes the limiting member 21 and guide plate 22 to rotate synchronously via the central shaft 2, so that one of the protrusions 313 engages in the groove 211 to position knob 1 at the stop of rotation. The two ends of the guide plate 22 are electrically in contact with the two bolts 352 respectively, and the current of the two conductive components 35 is conducted through the guide plate 22, so that the battery provides power to the vehicle electrical system. At the same time, the vehicle electrical system can detect the battery's operating status in real time and input the detection data into the circuit board 13 via the data line 33 for signal processing. Finally, a visual parameter interface is generated on the display screen 131, allowing the user to accurately assess the current health status of the battery.

[0047] When a user needs to disconnect the battery from the vehicle's electrical system after parking:

[0048] Rotating knob 1 in the opposite direction by 90° causes knob 1 to drive the limiting member 21 and guide plate 22 to rotate synchronously via the central shaft 2. This causes another protrusion 313 to engage in the groove 211 to position knob 1 at the stop of rotation. The two ends of the guide plate 22 respectively contact the two contact pieces 341, thereby cutting off the current flow between the two conductive components 35 and cutting off the electrical connection between the battery and the vehicle electrical system. This allows users to easily control the power supply between the battery and the vehicle electrical system and eliminates standby current to extend battery life.

[0049] This invention provides a car battery switch. The positive terminal of the battery is electrically connected to one of the conductive components via a power line, and the vehicle electrical system is electrically connected to another conductive component via a power line. The device is installed inside the vehicle. When starting the vehicle, the user rotates a knob to rotate the central shaft and guide plate, moving them above the conductive components. Simultaneously, the guide plate slides axially on the central shaft under the push of a spring, approaching the conductive components. This allows both ends of the guide plate to make electrical contact with the two conductive components, forming a complete current path to power the vehicle electrical system. After the vehicle stops, the user rotates the knob in the opposite direction to disconnect the guide plate from the two conductive components, cutting off the electrical connection between the battery and the vehicle electrical system. This allows the user to easily control the power supply between the battery and the vehicle electrical system, eliminates standby current, and extends battery life.

[0050] The vehicle electrical system is electrically connected to the data cable. When the battery is connected to the vehicle electrical system, the system can monitor the battery's operating status in real time and input the monitoring data into the circuit board for signal processing via the data cable. Finally, a visual parameter interface is generated on the display screen, allowing users to accurately assess the current health status of the battery and formulate maintenance strategies.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. 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 solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
