Description

Technical Field

[0001] This application relates to the field of circuit switch technology, and more particularly to a circuit switch and a vehicle. Background Technology

[0002] In related technologies, a circuit switch includes a housing, a first contact, a second contact, and a driving mechanism. The second contact and the driving mechanism are arranged sequentially and relative to each other in the height direction of the housing. The driving mechanism drives the first contact to move along the height direction of the housing so that the first contact can contact and separate from the second contact. When the first contact and the second contact are connected, the circuit switch is in a closed state. When the first contact and the second contact are separated, the circuit switch is in an open state.

[0003] It is understandable that, in the height direction of the housing, the space for the first contact to move away from the second contact is occupied by the drive mechanism, which makes the space for the first contact to move relatively small. Utility Model Content

[0004] This application provides a circuit switch and a vehicle, which are designed to allow for a large range of motion in the height direction of the housing, specifically in the first contact.

[0005] To achieve the above objectives, according to a first aspect of this application, a circuit switch is provided, comprising:

[0006] case;

[0007] The first contact is movably connected to the housing.

[0008] A second contact is disposed in the housing; and

[0009] A driving mechanism is provided in the housing. The driving mechanism is used to drive the first contact to move toward or away from the second contact in the height direction of the housing, so that the first contact and the second contact can contact and separate. In the height direction of the housing, the driving mechanism is offset from the second contact.

[0010] Optionally, the first contact is rotatably connected to the housing.

[0011] Optionally, the housing has a base, and the second contact is disposed on the base. In the length direction of the first contact, the first contact has a first end and a second end opposite to each other. The first end is used to contact and separate from the second contact. In the height direction of the housing, the second contact has a first side away from the base. When the first contact and the second contact are separated, the first end is higher than the second contact, and the second end is at least partially lower than the first side.

[0012] Optionally, the drive mechanism is located on the side of the second end opposite to the base;

[0013] And / or, the first contact has a first end that is bent, and the second contact has a second contact surface that is inclined away from the second end in the direction of the second contact near the base, and the first end is used to contact and separate from the second contact surface.

[0014] Optionally, the driving mechanism includes a driving member and a transmission member. The driving member is connected to the first contact through the transmission member. The driving member is used to drive the transmission member to move in the height direction of the housing, so that the transmission member drives the first contact to rotate.

[0015] Optionally, the transmission component is configured as a push-pull rod, with one end connected to the driving component and the other end connected to the first contact.

[0016] Optionally, the first contact includes a contact body and a rotating seat that are movably connected to each other, and the rotating seat is rotatably connected to the housing;

[0017] The drive mechanism can continue to drive the rotating seat when the contact body and the second contact are in contact, so that the contact body slides relative to the second contact.

[0018] Optionally, the contact body and the rotating seat are rotatably connected. When the contact body and the second contact are in contact, the driving mechanism drives the contact body and the rotating seat to rotate relative to each other, so that the contact body slides relative to the second contact.

[0019] Optionally, the first contact further includes an elastic element that connects the contact body and the rotating seat. When the contact body slides to the second contact, the elastic element tends to reset the contact body relative to the rotating seat.

[0020] Optionally, the first contact is provided with a sliding groove, and the driving mechanism is provided with a connecting end. The connecting end is movably disposed in the sliding groove and is used to slide in the sliding groove to drive the first contact to rotate relative to the housing.

[0021] According to a second aspect of this application, a vehicle is provided, including the aforementioned circuit switch.

[0022] In the circuit switch of this application embodiment, the driving mechanism drives the first contact to move toward or away from the second contact in the height direction of the housing, and the driving mechanism and the second contact are misaligned in the height direction of the housing. This ensures that the movement space of the first contact in the height direction of the housing is no longer occupied by the driving mechanism, thereby increasing the movement space of the first contact.

[0023] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

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

[0036] According to the first aspect of this application, referring to Figure 1 and Figure 2 This disclosure provides a circuit switch 100. The circuit switch 100 includes a housing 200, a first contact 300, a second contact 400, and a drive mechanism 500. The first contact 300 is movably connected to the housing 200. The second contact 400 is disposed in the housing 200. The drive mechanism 500 is disposed in the housing 200 and drives the first contact 300 to move toward or away from the second contact 400 in the height direction of the housing 200, so that the first contact 300 and the second contact 400 contact and separate. In the height direction of the housing 200, the drive mechanism 500 and the second contact 400 are offset from each other.

[0037] Since the drive mechanism 500 is used to drive the first contact 300 to move toward or away from the second contact 400 in the height direction of the housing 200, and the drive mechanism 500 and the second contact 400 are offset in the height direction of the housing 200, the drive mechanism 500 no longer occupies the space of the first contact 300 in the height direction of the housing 200, thereby increasing the space of the first contact 300.

[0038] There are many possible motion relationships between the first contact 300 and the housing 200. In some embodiments, the first contact 300 is rotatably connected to the housing 200. However, this design is not limited to this. In some other embodiments, the first contact 300 can move linearly relative to the housing 200.

[0039] In some embodiments, the housing 200 has a base 210, and a second contact 400 is disposed on the base 210. In the length direction of the first contact 300, the first contact 300 has a first end and a second end opposite to each other. The first end is used to contact and separate from the second contact 400. In the height direction of the housing 200, the second contact 400 has a first side away from the base 210. When the first contact 300 and the second contact 400 are separated, the first end is higher than the second contact 400, and the second end is at least partially lower than the first side.

[0040] Thus, when the first contact 300 and the second contact 400 separate, the second end being at least partially lower than the first side helps to increase the distance between the first end and the second contact 400. This also allows for greater movement space at the first end in the height direction of the housing 200.

[0041] In some embodiments, the drive mechanism 500 is located on the side of the second end opposite to the base 210.

[0042] Since the second end is at least partially lower than the first side in the first separation state, there is a large space on the side of the second end away from the base 210. The drive mechanism 500 is located on the side of the second end away from the base 210, which helps to improve the space utilization of the circuit switch 100.

[0043] There are many structural forms for the first contact 300 and the second contact 400. In some embodiments, the first contact 300 has a first end that is bent, and the second contact 400 has a second contact surface 431. The second contact surface 431 is inclined away from the second end in the direction of the second contact 400 near the base 210, and the first end is used to contact and separate from the second contact surface 431. However, this design is not limited to this. In some other embodiments, the structural forms of the first contact 300 and the second contact 400 may refer to, but are not limited to, related technologies, and are not limited here.

[0044] Reference Figure 7 The drive mechanism 500 has many structural forms. In some embodiments, the drive mechanism 500 includes a drive member 510 and a transmission member 520. The drive member 510 is connected to the first contact 300 through the transmission member 520. The drive member 510 drives the transmission member 520 to move in the height direction of the housing 200, so that the transmission member 520 drives the first contact 300 to rotate. In this way, the drive member 510 indirectly drives the first contact 300 through the transmission member 520.

[0045] However, this design is not limited to this. In some other embodiments, the drive mechanism 500 is configured as a drive element 510, which directly drives the first contact 300.

[0046] The transmission component 520 can have many structural forms. In some embodiments, the transmission component 520 is configured as a push-pull rod, with one end connected to the drive component 510 and the other end connected to the first contact 300. However, this design is not limited to this. In some other embodiments, the transmission component 520 may also be plate-shaped, but is not limited to this.

[0047] There are many types of driving methods for the driving member 510. In some embodiments, the driving member 510 drives the transmission member 520 electromagnetically. In this way, the driving member 510 can engage and disengage the transmission member 520, so that the transmission member 520 drives the first contact 300 to rotate relative to the housing 200, thereby causing the first contact 300 to contact and separate from the second contact 400.

[0048] However, this design is not limited to this. In some other embodiments, the driving form of the driving member 510 may also be, but is not limited to, the related technology. No restrictions are imposed here, as long as it can drive the first contact 300 to rotate relative to the housing 200.

[0049] Reference Figures 3 to 5 In some embodiments, the first contact 300 includes a contact body 310 and a rotating seat 320 that are movably connected to each other, and the rotating seat 320 is rotatably connected to the housing 200.

[0050] The drive mechanism 500 can continue to drive the rotating seat 320 when the contact body 310 and the second contact 400 are in contact, so that the contact body 310 slides relative to the second contact 400.

[0051] Thus, when the contact body 310 and the second contact 400 come into contact, the drive mechanism 500 drives the contact body 310 and the rotating seat 320 to move relative to each other, so that the contact body 310 slides relative to the second contact 400, and the contact body 310 grinds against the second contact 400.

[0052] There are many ways for the contact body 310 and the rotating seat 320 to move relative to each other. In some embodiments, the contact body 310 and the rotating seat 320 are rotatably connected. When the contact body 310 and the second contact 400 are in contact, the driving mechanism 500 drives the contact body 310 and the rotating seat 320 to rotate relative to each other so that the contact body 310 slides relative to the second contact 400.

[0053] However, this design is not limited to this. In some other embodiments, the relative movement of the contact body 310 and the rotating seat 320 can also be, but is not limited to, the related technology. No limitation is made here, as long as the driving mechanism 500 can continue to drive the rotating seat 320 when the contact body 310 and the second contact 400 are in contact, so that the contact body 310 slides relative to the second contact 400.

[0054] In some embodiments, the first contact 300 further includes an elastic element 330, which is connected to the contact body 310 and the rotating seat 320. When the contact body 310 slides in the second contact 400, the elastic element 330 has a tendency to reset the contact body 310 relative to the rotating seat 320.

[0055] In this way, as the contact body 310 slides against the second contact 400, the elastic potential energy generated by the deformation of the elastic element 330 acts on the contact body 310. This results in a greater pressure between the contact body 310 and the second contact 400, thereby improving the grinding effect between the contact body 310 and the second contact 400. It is worth mentioning that, in one example, the elastic element 330 may be configured as, but is not limited to, a spring.

[0056] There are many ways to connect the drive mechanism 500 to the first contact 300. In some embodiments, the first contact 300 is provided with a slide groove 323, and the drive mechanism 500 is provided with a connecting end. The connecting end is movably provided in the slide groove 323 and is used to slide in the slide groove 323 to drive the first contact 300 to rotate relative to the housing 200.

[0057] However, this design is not limited to this. In some other embodiments, the connection between the drive mechanism 500 and the first contact 300 can be, but is not limited to, the related technology. No restrictions are imposed here, as long as the drive mechanism 500 can drive the first contact 300 to rotate relative to the housing 200.

[0058] In one example, the first contact 300 includes a contact body 310, a rotating seat 320, and an elastic element 330. The contact body 310 and the rotating seat 320 are rotatably connected, and the contact body 310 has a first contact surface 312. The rotating seat 320 is rotatably connected to the housing 200 to have a first axis of rotation 313, and the rotating seat 320 has a groove 323. The elastic element 330 connects the contact body 310 and the rotating seat 320.

[0059] The second contact 400 is provided with a second contact surface 431.

[0060] The drive mechanism 500 includes a drive component 510 and a push-pull rod. The drive component 510 is connected to the first contact 300 via the push-pull rod, which has a connecting end located in the slide groove 323. The drive component 510 achieves contact and separation of the first contact surface 312 and the second contact surface 431 by electromagnetically attracting and releasing the push-pull rod.

[0061] The first rotating shaft 313 is positioned between the first contact surface 312 and the connecting end. The connecting end has a height difference from the side of the housing 200 near the drive member 510.

[0062] When the drive unit 510 engages the push-pull rod, the push-pull rod applies torque to the first contact 300, causing the first contact surface 312 and the second contact surface 431 to come into contact. At this time, the connecting end and the first rotating shaft 313 are substantially level in the height direction of the housing 200.

[0063] During the process of the drive unit 510 releasing the push-pull rod, the connecting end moves towards the side of the housing 200 closer to the drive unit 510. When the push-pull rod is released to its maximum stroke, it stops and remains there. At this time, the circuit switch 100 disconnects the circuit.

[0064] By rationally setting the position of the connection end, the circuit switch 100 makes full use of the space between the connection end and the side of the housing 200 near the drive member 510 to provide the space required after releasing the push-pull rod. While achieving a larger opening distance, the circuit switch 100 is more compact in the height direction, and the overall volume is reduced.

[0065] Furthermore, the drive unit 510 uses electromagnetic drive to push and pull the rod, which makes the structure of the drive unit 510 simple and easy to achieve a high mechanical life.

[0066] In addition, the circuit switch 100 also includes an arc extinguishing device, which means that the circuit switch 100 does not need to be replaced after disconnecting the short circuit current and can be reused after the short circuit fault is cleared, which can reduce the user's vehicle operating costs.

[0067] The circuit switch 100 includes a housing 200, a second contact 400, a first contact 300, a drive mechanism 500, a wiring harness 600, and a connection terminal 700. The drive mechanism 500 is equipped with a drive element 510 and a push-pull rod. The drive element 510 can electromagnetically engage and release the push-pull rod. Engaging and releasing the push-pull rod drives the first contact 300 to rotate relative to the housing 200, thereby achieving contact and separation between the first contact surface 312 and the second contact surface 431. A first rotating shaft 313 is located between the connection end and the first contact surface 312. The connection end has a height difference from the side of the housing 200 closest to the drive element 510. When the drive unit 510 engages the push-pull rod, the push-pull rod applies torque to the first contact 300 to keep the first contact surface 312 in contact with the second contact surface 431. At this time, the connecting end of the push-pull rod and the first rotating shaft 313 are basically parallel in the height direction of the housing 200. During the process of the drive unit 510 releasing the push-pull rod, the connecting end moves towards the side of the housing 200 closer to the drive unit 510. When the push-pull rod is released to its maximum stroke, it stops and remains there. At this time, the circuit switch 100 is in the off state.

[0068] Reference Figure 6The second contact 400 is fixedly disposed on the housing 200. The second contact 400 includes a first terminal portion 410, a current-carrying portion 420 and a second contact portion 430. The second contact portion 430 is provided with a second contact surface 431. The first terminal portion 410 is used to connect with an external circuit, and the second contact surface 431 is used to contact and disconnect with the first contact surface 312 to realize the switching on and off.

[0069] The first contact 300 is rotatably mounted on the housing 200. The first contact 300 includes a rotating base 320, a contact body 310, and an elastic element 330. The elastic element 330 is configured as a spring. One end of the contact body 310 is provided with a first contact portion 311, which has a first contact surface 312. The first contact surface 312 is used to contact and disconnect with the second contact surface 431 to realize the switching on and off. The other end of the contact body 310 is provided with a first connecting portion 314 for current-carrying connection with the connecting terminal 700. A first rotating shaft 313 is provided between the first contact portion 311 and the first connecting portion 314. It can be understood that in the length direction of the contact body 310, the first contact portion 311, the first rotating shaft 313, and the first connecting portion 314 are connected in sequence. The contact body 310 is rotatably mounted on the rotating base 320 through the first rotating shaft 313 and is in close contact with the rotating base 320 under the action of the elastic element 330. In addition, the first rotating shaft 313 has a first rotating shaft 313 line.

[0070] The rotating seat 320 is provided with a second rotating shaft 321 and a seat body 322. The seat body 322 is used to connect with the connecting end of the push-pull rod. The drive connecting end is provided with a connecting shaft 521, and the seat body 322 is connected to the connecting shaft 521. The first connecting part 314 is provided with a sliding groove 323. The sliding groove 323 includes a first groove wall 324 and a second groove wall 325 that are parallel to each other. The first groove wall 324 and the second groove wall 325 are arranged opposite to each other, and the first groove wall 324 is farther away from the drive member 510 than the second groove wall 325.

[0071] The drive mechanism 500 is an electromagnetic structure and is fixedly mounted on the housing 200. The drive mechanism 500 includes a drive member 510 and a push-pull rod that can be attracted and released. The connecting end of the push-pull rod is provided with a connecting shaft 521. The connecting shaft 521 is connected to the seat body 322 of the rotating seat 320. During the process of the drive member 510 attracting the push-pull rod, the connecting shaft 521 contacts the second groove wall 325 to control the first contact 300 to rotate in the direction of closing the circuit switch 100. During the process of the drive member 510 releasing the push-pull rod, the connecting shaft 521 contacts the first groove wall 324 to control the first contact 300 to rotate in the direction of opening the circuit switch 100.

[0072] One end of the wire harness 600 is connected to the connection part of the contact body 310 for current carrying, and the other end is connected to the connection terminal 700 for current carrying;

[0073] The connection terminal 700 is fixedly mounted on the housing 200. The connection terminal 700 includes a second terminal portion 710 and a second connection portion 720. The second terminal portion 710 is used to connect to an external line, and the second connection portion 720 is used to make a current-carrying connection with the wire harness 600.

[0074] The circuit switch 100 includes a closed state and an open state. When the push-pull rod of the drive mechanism 500 is in the released state, the switch is in the open state; when the push-pull rod of the drive mechanism 500 is in the attracted state, the switch is in the closed state.

[0075] When the push-pull rod begins to switch from the released state to the engaged state, it drives the first contact 300 to rotate in the first direction. During this process, the contact body 310 and the rotating seat 320 rotate synchronously around the connecting end as the center, until the first contact surface 312 and the second contact surface 431 initially make contact. At this time, the contact position between the first contact surface 312 and the second contact surface 431 is the first contact position. The center is as follows: Figure 1 As shown in Figure A, the push-pull rod continues to move in the attraction direction, the rotating seat 320 continues to rotate around the connecting end, and the first rotating shaft 313 continues to rotate with the rotating seat 320. Due to the constraint of the second contact surface 431, the contact body 310 is no longer in contact with the rotating seat 320 and begins to overcome the elastic potential energy of the elastic element 330, rotating in the second direction around the first rotating shaft 313. Because the first rotating shaft 313 is not concentric with the connecting end, the contact position between the first contact surface 312 and the second contact surface 431 also changes. When the push-pull rod stops moving to the attraction state, the rotating seat 320 and the contact body 310 stop moving, and the circuit switch 100 is in the closed state. At this time, the contact position between the first contact surface 312 and the second contact surface 431 is the second contact position. During the movement of the first contact surface 312 from the first contact position to the second contact position, grinding occurs between the first contact surface 312 and the second contact surface 431, and the distance between the first contact position and the second contact position is the grinding distance.

[0076] When the push-pull rod begins to move from the engaged to the released state, it drives the rotating seat 320 to rotate in a second direction, which is opposite to the first direction. During this process, the first rotating shaft 313 continues to rotate with the rotating seat 320 about the connecting end as the center, and the contact body 310 rotates about the first rotating shaft 313 as the center in the first direction. Figure 1As shown in Figure B, because the first rotating shaft 313 is not concentric with the connecting end, the contact position between the first contact surface 312 and the second contact surface 431 also changes, moving from the second contact position to the first contact position. When the rotating seat 320 continues to rotate until it is in contact with the contact body 310, the first contact surface 312 moves to the first contact position. Afterwards, the contact body 310 and the rotating seat 320 rotate in the second direction with the synchronous connecting end as the center. When the push-pull rod continues to move to the released state and stops, the first contact 300 stops moving, and the switch is in the open state.

[0077] During the switching process between the closed and open states of the circuit switch 100, the first contact surface 312 and the second contact surface 431 are repeatedly ground between the grinding gaps to clean the oxide layer and other substances on the surface of the first contact surface 312 and the second contact surface 431, thereby achieving a self-cleaning function. This prevents the first contact 300 and the second contact 400 from burning out due to excessive contact internal resistance, thus improving circuit safety.
