Description

Technical Field

[0001] This application relates to the field of seat switch technology, and in particular to a seat switch mechanism and an assembly fixture for the seat switch mechanism. Background Technology

[0002] Currently, the seat switch on ride-on lawnmowers serves two purposes: first, when a person is on the seat, the switch is activated, allowing the vehicle to move and perform other functions; second, when the person leaves the seat, the switch deactivates, cutting off power and ensuring the vehicle's safety. However, current seat switches often fail to activate when a person is on the seat, or fail to deactivate when the person leaves, compromising overall vehicle safety. Utility Model Content

[0003] The purpose of this application is to provide a seat switch mechanism and an assembly fixture for the seat switch mechanism, which solves the problem that the seat switch cannot be turned on when a person is in the seat and cannot be turned off when the person leaves the seat.

[0004] To achieve the above objectives, this application provides a seat switch mechanism, comprising:

[0005] Switch body;

[0006] A switch bracket is used to mount the switch body and also to be movably connected to the vehicle frame to adjust the position of the switch body.

[0007] Fixed bracket, attached to the vehicle frame;

[0008] A switch plate is movably mounted on a fixed bracket for moving between a first position and a second position, so as to maintain a preset gap with the switch bracket and trigger the switch body in the first position, and to disengage from the switch body in the second position.

[0009] An elastic element, disposed between the switch plate and the fixed bracket, is used to provide an elastic force so that the switch plate tends to move from the first position to the second position;

[0010] Fasteners, located at the connection between the switch bracket and the vehicle frame, are used to secure the switch bracket to the vehicle frame when the switch bracket and the switch pressure plate in the first position are maintained at a preset gap.

[0011] In some embodiments, the switch plate is provided with at least two guide posts, and the fixed bracket is provided with at least two bushings. The guide posts and the corresponding bushings are slidably engaged, so that the switch plate slides relative to the fixed bracket.

[0012] In some embodiments, the end of the guide post away from the switch plate is provided with a threaded surface, and a limit nut is threadedly connected to the threaded surface. The limit nut contacts and abuts against the bushing to limit the travel of the switch plate.

[0013] In some embodiments, at least two elastic elements are provided, and the elastic elements are sleeved on the corresponding guide posts, with the two ends of the elastic elements abutting against the switch pressure plate and the bushing, respectively.

[0014] In some embodiments, the switch plate includes:

[0015] The pressure plate body is used to connect with the guide post;

[0016] The bent body is integrally set on the side of the pressure plate body near the switch body, and is used to trigger the trigger part of the switch body to conduct the switch body.

[0017] In some embodiments, the pressure plate body includes a first plate and two second plates integrally disposed on the first plate, the two second plates being symmetrically disposed on both sides of the guide post so that the pressure plate body is U-shaped.

[0018] In some embodiments, the switch bracket is L-shaped and includes a mounting plate and a fixing plate. The mounting plate is used to mount the switch body, and the fixing plate is used to fix it to the vehicle frame by fasteners. The bending body includes a third plate and a fourth plate. The fourth plate is arranged parallel to the mounting plate, and the third plate is connected between the fourth plate and the pressure plate body.

[0019] This application also provides an assembly fixture for a seat switch mechanism, used to assemble any of the above-mentioned seat switch mechanisms. The assembly fixture includes:

[0020] A locking plate is used to lock onto the fixing bracket and the switch pressure plate of the seat switch mechanism so that the switch pressure plate is in the first position;

[0021] A pad is used to place between the switch plate and the switch body of the seat switch mechanism to maintain a preset gap between the switch plate and the switch bracket of the seat switch mechanism.

[0022] In some embodiments, the card plate includes a first card wall and a second card wall, which are arranged in parallel and a slot is formed between them. The first card wall and the second card wall respectively contact and abut against the switch pressure plate and the fixed bracket so that the switch pressure plate and the fixed bracket are locked in the slot.

[0023] In some embodiments, the pad is provided with a clearance groove for avoiding the trigger portion of the switch body.

[0024] Compared to the aforementioned background technology, the seat switch mechanism provided in this application includes a switch body, a switch bracket, a fixed bracket, a switch pressure plate, an elastic element, and fasteners. The switch bracket is used to mount the switch body and is also movably connected to the vehicle frame to adjust the position of the switch body. The fixed bracket is fixed to the vehicle frame. The switch pressure plate is movably fitted into the fixed bracket and is used to move between a first position and a second position. In the first position, it maintains a preset gap with the switch bracket and triggers the switch body; in the second position, it disengages from the switch body. The elastic element is disposed between the switch pressure plate and the fixed bracket, and provides elastic force to give the switch pressure plate a tendency to move from the first position to the second position. The fasteners are disposed at the connection between the switch bracket and the vehicle frame, and are used to fix the switch bracket to the vehicle frame when the switch bracket and the switch pressure plate in the first position maintain a preset gap.

[0025] During assembly, first, the switch body is installed on the switch bracket, which is then mounted on the vehicle frame using fasteners. The fasteners are not tightened immediately. Next, the switch pressure plate is passed through the elastic element and embedded in the fixed bracket, which is also mounted on the vehicle frame. The elastic element is positioned between the switch pressure plate and the fixed bracket. Then, the switch pressure plate is placed in the first position, with the elastic element in a state where its elastic force is to be released. The switch bracket and the switch pressure plate in the first position are kept at a preset gap. Finally, the fasteners are tightened on the vehicle frame. This is the state where a person is seated. At this time, the switch body is in the conducting state. After the person leaves the seat, the switch pressure plate returns to its original position under the elastic force of the elastic element, and the switch body is in the disengaged state.

[0026] This seat switch mechanism is designed so that the switch body is in an off state when a person leaves the seat and in a conducting state when a person is in the seat. In other words, when a person is in the seat, the switch body is conducting, allowing the vehicle to drive and perform other vehicle functions. When a person leaves the seat, the switch body is off, cutting off the power to the vehicle and ensuring vehicle safety. This achieves the function of cutting off power when a person leaves the seat and keeping power on when a person is in the seat, solving the problem that the seat switch cannot be turned on when a person is in the seat and cannot be turned off when a person leaves the seat.

[0050] The seat switch mechanism provided in this application embodiment includes a switch body 10, a switch bracket 20, a fixed bracket 30, a switch pressure plate 40, an elastic element 50, and a fastener 60.

[0051] The switch body 10 is used to disconnect when a person leaves the seat and to connect when a person is in the seat.

[0052] The switch bracket 20 is used to mount the switch body 10. At the same time, the switch bracket 20 is also used to be movably connected to the frame 80 to adjust the position of the switch body 10.

[0053] The fixed bracket 30 is fixed to the vehicle frame 80, and the fixed bracket 30 serves as the mounting carrier for the switch pressure plate 40 and the elastic element 50.

[0054] The switch plate 40 is movably mounted on the fixed bracket 30. The switch plate 40 is used to move between a first position and a second position, so that it maintains a preset gap with the switch bracket 20 and triggers the switch body 10 in the first position, and disengages from the switch body 10 in the second position.

[0055] An elastic element 50 is disposed between the switch plate 40 and the fixed bracket 30. The elastic element 50 provides an elastic force to give the switch plate 40 a tendency to move from a first position to a second position. Of course, the elastic element 50 can be a compression spring.

[0056] Fastener 60 is provided at the connection between switch bracket 20 and frame 80. Fastener 60 is used to fix switch bracket 20 to frame 80 when switch bracket 20 and switch pressure plate 40 in first position are kept at a preset gap.

[0057] It should be noted that the aforementioned preset gap refers to the gap that ensures the switch plate 40 disengages from the switch body 10 after the person leaves the seat and that the switch plate 40 triggers the switch body 10 when the person is on the seat. This preset gap should not be too large or too small. If the preset gap is too large, it cannot be guaranteed that the switch plate 40 will successfully trigger the switch body 10 when the person is on the seat. If the preset gap is too small, it cannot be guaranteed that the switch body 10 will completely disengage from the switch body 10 after the person leaves the seat.

[0058] During assembly, firstly, the switch body 10 is installed on the switch bracket 20, and the switch bracket 20 is assembled onto the vehicle frame 80 by fasteners 60. Fasteners 60 are not tightened at this time. Then, the switch pressure plate 40 is passed through the elastic member 50 and embedded in the fixed bracket 30, which is assembled onto the vehicle frame 80. The elastic member 50 is located between the switch pressure plate 40 and the fixed bracket 30. Next, the switch pressure plate 40 is placed in the first position, and the elastic member 50 is in a state of waiting to release elastic force. The switch bracket 20 and the switch pressure plate 40 in the first position are kept at a preset gap. Finally, the fasteners 60 are tightened onto the vehicle frame 80. This state is the state in which a person is in the seat. At this time, the switch body 10 is in the conducting state. After the person leaves the seat, the switch pressure plate 40 returns to its original position under the elastic force of the elastic member 50. At this time, the switch body 10 is in the disengaged state.

[0059] This seat switch mechanism is designed so that the switch body 10 is in an off state when a person leaves the seat and in a conducting state when a person is in the seat. In other words, when a person is in the seat, the switch body 10 is conducting, and the vehicle can be driven and perform other vehicle functions. When a person leaves the seat, the switch body 10 is disconnected, and the vehicle loses power, ensuring the safety of the vehicle. This achieves the function of power off when a person leaves the seat and power on when a person is in the seat, solving the problem that the seat switch cannot be turned on when a person is in the seat and cannot be turned off when a person leaves the seat.

[0060] To facilitate the movement and cooperation between the switch plate 40 and the fixed bracket 30, the switch plate 40 is provided with at least two guide posts 43, and the fixed bracket 30 is provided with at least two bushings 31. The guide posts 43 and the corresponding bushings 31 are slidably engaged, so that the switch plate 40 slides relative to the fixed bracket 30.

[0061] At the same time, at least two elastic elements 50 are provided, and the elastic elements 50 are sleeved on the corresponding guide post 43. The two ends of the elastic elements 50 abut against the switch pressure plate 40 and the bushing 31 respectively.

[0062] In some embodiments, there are two guide posts 43 and two bushings 31. The two guide posts 43 are slidably engaged with the two bushings 31 respectively, and the switch plate 40 is slidably (nested) engaged with the two bushings 31 on the fixed bracket 30 through the two guide posts 43.

[0063] In some embodiments, the end of the guide post 43 away from the switch plate 40 is provided with a threaded surface 431, and a limit nut 70 is threadedly connected to the threaded surface 431. The limit nut 70 contacts and abuts against the bushing 31 to limit the travel of the switch plate 40.

[0064] In other words, in order to prevent the switch plate 40 from having too large a stroke, a limit nut 70 is set to contact and cooperate with the bushing 31 to ensure that the movement displacement of the switch plate 40 under the action of the elastic element 50 will not be too large after the person leaves the seat.

[0065] Based on the above, there are also two elastic elements 50. The two elastic elements 50 are respectively sleeved on the two guide posts 43, and the two ends of the elastic elements 50 abut against the switch pressure plate 40 and the bushing 31 respectively.

[0066] In this way, after a person sits on the seat, the switch plate 40 moves down and the elastic element 50 is compressed until the switch plate 40 moves to the first position. After the person leaves the seat, the switch plate 40 moves up under the elastic force of the elastic element 50 until it moves to the second position and stops. At this time, it can be understood that the limit nut 70 just contacts and abuts against the bushing 31.

[0067] In some embodiments, the switch plate 40 includes a plate body 41 and a bending body 42. The plate body 41 is used to connect with the guide post 43, which is located on the side of the plate body 41 near the fixed bracket 30. The bending body 42 is integrally disposed on the side of the plate body 41 near the switch body 10, and is used to trigger the triggering part of the switch body 10 to turn on the switch body 10.

[0068] In this embodiment, the pressure plate body 41 includes a first plate 411 and two second plates 412 integrally disposed on the first plate 411. The two second plates 412 are symmetrically disposed on both sides of the guide post 43 so that the pressure plate body 41 is U-shaped.

[0069] Furthermore, the switch bracket 20 is L-shaped and includes a mounting plate 21 and a fixing plate 22. The mounting plate 21 is used to mount the switch body 10, and the fixing plate 22 is used to fix it to the frame 80 by fasteners 60. The bending body 42 includes a third plate 421 and a fourth plate 422. The fourth plate 422 is arranged parallel to the mounting plate 21, and the third plate 421 is connected between the fourth plate 422 and the pressure plate body 41.

[0070] The present application provides an assembly fixture for a seat switch mechanism, used in the seat switch mechanism described in the above specific embodiments. The assembly fixture includes a clamping plate 90 and a pad 100. The clamping plate 90 is used to clamp onto the fixing bracket 30 and the switch pressure plate 40 of the seat switch mechanism, so that the switch pressure plate 40 is in a first position; the pad 100 is used to pad between the switch pressure plate 40 and the switch body 10 of the seat switch mechanism, so that the switch pressure plate 40 and the switch bracket 20 of the seat switch mechanism maintain a preset gap.

[0071] In some embodiments, the card plate 90 includes a first card wall 91 and a second card wall 92, which are arranged in parallel. A card groove 93 is formed between the first card wall 91 and the second card wall 92. The first card wall 91 and the second card wall 92 respectively contact and abut against the switch pressure plate 40 and the fixed bracket 30 so that the switch pressure plate 40 and the fixed bracket 30 are locked in the card groove 93.

[0072] It can be seen that the card plate 90 forms a U-shaped slot 93 through the first card wall 91 and the second card wall 92, which is used to hold the switch plate 40 and the fixed bracket 30 in it, thereby ensuring that the switch plate 40 is in the first position (which can be considered as the lowest position within the range formed by the switch plate 40).

[0073] In some embodiments, the pad 100 is provided with a clearance groove 101, which is used to avoid the trigger portion of the switch body 10.

[0074] In other words, the trigger part of the switch body 10 can be exposed on the pad 100 so that when the switch plate 40 moves to the first position, the body 42 bends to trigger the trigger part.

[0075] During assembly, firstly, the switch body 10 is installed on the switch bracket 20, which is then mounted on the vehicle frame 80 via fasteners 60, but not yet tightened. Next, the switch pressure plate 40 is passed through the elastic element 50 and embedded in the fixed bracket 30, which is mounted on the vehicle frame 80. The elastic element 50 is located between the switch pressure plate 40 and the fixed bracket 30. Then, the locking plate 90 is locked onto the switch pressure plate 40 and the fixed bracket 30, at which point the switch pressure plate 40 is in the first / lowest position. Next, the pad 100 is placed between the switch pressure plate 40 and the switch body 10. Finally, the fasteners 60 are tightened onto the vehicle frame 80, at which point the switch body 10 is in the conductive state. When the locking plate 90 is removed, the switch pressure plate 40 returns to its original position via the elastic element 50, at which point the switch body 10 is disconnected, realizing the function of power off when the person leaves the seat and power on when the person is in the seat.

[0076] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0077] The seat switch mechanism and its assembly fixture provided in this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
