Description

Technical Field

[0001] This application relates to the field of electric vehicle parts technology, and in particular to a sensor-activated seat. Background Technology

[0002] With the popularization of electric vehicles, electric vehicles have become the mainstream means of transportation for short-distance travel in modern cities. As an important component that comes into direct contact with the rider, the seat is mainly used to improve the riding comfort during use. Existing electric vehicle seats are usually composed of three parts: an outer leather layer, a middle sponge layer, and an inner base, which are spliced ​​together in sequence.

[0003] However, existing electric vehicle seats have limited functionality. When the vehicle is powered on and the driver temporarily leaves the driver's seat, if the driver or a third party accidentally touches the throttle, buttons, or other control components, causing the power system to start, the vehicle is very likely to suddenly accelerate abnormally, leading to loss of control, collision damage, or even personal injury. This greatly reduces the safety of electric vehicles during use and has obvious shortcomings. Utility Model Content

[0004] To improve the safety of electric vehicle use, this application provides a sensor-activated seat.

[0005] The sensor-activated seat provided in this application adopts the following technical solution:

[0006] A sensor-activated seat includes a base with a sponge layer on it, a fixing seat on the base, and multiple switch seats on the fixing seat. Each switch seat has a micro switch embedded in it. The fixing seat has a trigger for activating the micro switch. When the driver sits down in the seat, the sponge layer presses against the fixing seat, causing the trigger to deform and activate the micro switch, thus turning it on.

[0007] By adopting the above technical solution, when the driver is sitting in the seat, the driver's own weight compresses the sponge layer, causing deformation. The sponge layer compresses the trigger element towards the fixed seat. After being compressed, the trigger element undergoes elastic deformation, thus pressing the micro switch. At this time, the micro switch is turned on, and the driver can start the power system through the control components. When no driver is sitting in the seat, the sponge layer maintains its original shape, and the trigger element does not undergo elastic deformation and separates from the micro switch, thus causing the power system to fail. At this time, even if the throttle button or other control components are accidentally touched, the vehicle cannot start or accelerate, effectively avoiding safety accidents caused by accidental operation after the person leaves the driver's seat, and improving the safety during the use of electric vehicles.

[0008] Optionally, the trigger includes a first spring, which is mounted on two switch holders on opposite sides of the fixed base. The coverage area of ​​the first spring includes a plurality of microswitches. In its natural state, the first spring and the plurality of microswitches are in a non-contact state.

[0009] By adopting the above technical solution, when the driver sits down, the sponge layer squeezes the first spring, the first spring undergoes elastic deformation and simultaneously touches multiple microswitches on the fixed seat. At this time, the microswitches are turned on, and the driver can start the power system by operating the components. When the driver leaves the seat, the sponge layer returns to its original shape, and the first spring returns to the state of being separated from the microswitches under its own elasticity, thereby causing the power system to fail.

[0010] Optionally, the base has a fixing groove that mates with the fixing seat, the inner side wall of the fixing groove has multiple positioning grooves, and the outer periphery of the fixing seat has positioning blocks that correspond one-to-one with the multiple positioning grooves, the positioning blocks being inserted into the positioning grooves.

[0011] By adopting the above technical solution, the positioning of the fixed seat on the base can be quickly achieved through the cooperation between the positioning block and the positioning groove during the installation of the fixed seat, thereby improving the convenience of installation for workers.

[0012] Optionally, the positioning block can be detachably connected to the base via connecting bolts.

[0013] By adopting the above technical solution, the setting of the connecting bolts enables detachable installation between the fixed seat and the base, which facilitates maintenance by workers when the micro switch fails or the trigger element fails, and improves the convenience of workers' operation.

[0014] Optionally, the bottom surface of the mounting base is provided with a cable routing groove for cable routing.

[0015] By adopting the above technical solution, the wiring trough provides a dedicated channel for the wiring of sensing components such as microswitches, which can effectively reduce the possibility of the wiring being damaged due to squeezing and friction inside the seat, and improve the safety and service life of the wiring.

[0016] Optionally, the trigger includes a second spring corresponding to each of the plurality of microswitches. The second spring is disposed on the switch base corresponding to the microswitch and covers the corresponding microswitch. In its natural state, the second spring and the corresponding microswitch are in a non-contact state.

[0017] By adopting the above technical solution, when the driver sits down, the sponge layer compresses multiple second springs, which undergo elastic deformation and simultaneously touch the corresponding microswitches. When one of the second springs fails due to elastic fatigue, the other second springs and microswitches can still work normally, reducing the risk of the entire sensing system being paralyzed due to the failure of a single component. At the same time, workers only need to replace a single second spring and microswitch to carry out maintenance, reducing maintenance costs.

[0018] Optionally, a connecting component is provided at the connection between the trigger and the switch base, and the trigger is detachably connected to the switch base via the connecting component.

[0019] By adopting the above technical solution, when the trigger element fails to work due to elastic fatigue or breakage, maintenance personnel only need to remove the damaged trigger element from the switch base through the connecting assembly. This eliminates the need to replace multiple switch bases and trigger elements on the fixed base as a whole, thereby improving the efficiency of worker maintenance and reducing maintenance costs.

[0020] Optionally, the connecting assembly includes a connecting seat disposed on the trigger element. The connecting seat and the switch base are provided with interconnecting connecting grooves. A connecting shaft is rotatably connected inside the connecting groove. One end of the connecting shaft is provided with a stop block, and the other end is provided with a plurality of elastic retaining strips evenly distributed circumferentially. Each elastic retaining strip is provided with a hook portion, and each hook portion is provided with a transition slope. In the natural state, the hook portion of the elastic retaining strip extends out of the connecting groove and abuts against the outer surface of the switch base.

[0021] By adopting the above technical solution, when disassembling the damaged trigger, the worker pinches multiple elastic clips to make them contract inward under force, and the hook part is disengaged from the outer surface of the switch seat. Then the connecting shaft is pulled out from the connecting groove, and finally the worker lifts the connecting seat upward to make it detach from the switch seat. This is how the damaged trigger is disassembled.

[0022] When installing the trigger, the worker first aligns the connecting seat with the connecting groove of the switch seat. Then, using the guiding effect of the transition slope, the connecting shaft is inserted into the connecting groove. At this time, the elastic retaining strip is in an inward contraction state. When the hook extends out of the connecting groove, the elastic retaining strip opens outward with its own elasticity, so that the hook abuts against the outer surface of the switch seat. At the same time, the stop block can effectively prevent the connecting shaft from being over-inserted or dislodged. In this way, the new trigger is installed and fixed to the switch seat. The setting of the connecting component allows the worker to disassemble and assemble without the need for complicated tools, thus improving assembly efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a fixed seat, a trigger and a micro switch, when no driver is sitting in the seat, the sponge layer maintains its original shape and the trigger does not undergo elastic deformation and separate from the micro switch, thereby causing the power system to fail. At this time, even if the throttle button or other control components are accidentally touched, the vehicle cannot start or accelerate, effectively avoiding safety accidents caused by misoperation after the person leaves the driver's seat, and improving the safety of electric vehicles during use.

[0025] 2. By setting up a connecting component, when the trigger element fails to work due to elastic fatigue or breakage, maintenance personnel only need to remove the damaged trigger element from the switch base through the connecting component, thus eliminating the need to replace multiple switch bases and trigger elements on the fixed base as a whole, thereby improving the efficiency of worker maintenance and reducing maintenance costs.

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses a sensor-activated seat.

[0035] Example 1

[0036] Reference Figure 1 and Figure 2 A sensor-activated seat includes a base 1, which serves as a basic support component and is connected to the electric vehicle body through a preset mounting hole or connection structure. A sponge layer 2, which provides comfortable cushioning support for the driver and passengers, is fixedly connected to the upper surface of the base 1. The outer surface of the sponge layer 2 is covered with a leather layer (not shown in the figure).

[0037] Reference Figure 1 and Figure 2 The base 1 has a fixing groove 3, and a fixing seat 4 is installed inside the fixing groove 3. The fixing seat 4 matches the shape and size of the fixing groove 3.

[0038] Reference Figure 2 and Figure 3 The fixed base 4 is provided with multiple switch bases 5 along its length. In this embodiment, there are three switch bases 5. Each switch base 5 is embedded with a micro switch 51. The micro switch 51 is electrically connected to the power system of the electric vehicle through the controller. The bottom surface of the fixed base 4 is provided with a wire groove to facilitate the wiring. After the fixed base 4 is installed, the worker connects the wire of the micro switch 51 to the controller through the wire groove. The wire groove reduces the possibility of the wire being damaged due to squeezing and friction inside the seat.

[0039] Reference Figure 2 and Figure 3 The fixed base 4 is provided with a trigger element 6 for triggering the micro switches 51. The trigger element 6 includes a first spring 61, which is made of elastic metal material and is parallel to the length direction of the fixed base 4. The first spring 61 is mounted on two switch seats 5 on opposite sides of the fixed base 4. In this embodiment, the first spring 61 is fixedly installed on the first switch seat 5 and the third switch seat 5. The coverage area of ​​the first spring 61 includes three micro switches 51. In its natural state, the first spring 61 and the three micro switches 51 are in a non-contact state, ensuring that it will not be accidentally triggered when no force is applied.

[0040] During the use of the electric vehicle, when the driver sits on the seat, the driver's own weight compresses the sponge layer 2 and causes deformation. The sponge layer 2 compresses the first spring 61 in the direction of the fixed seat 4. After being compressed, the first spring 61 undergoes elastic deformation and presses the micro switch 51. At this time, the micro switch 51 is turned on, and the controller receives the turn signal, allowing the driver to start the electric vehicle power system through the control components such as the throttle button.

[0041] When the driver leaves the seat, the weight of the human body above the sponge layer 2 disappears, the sponge layer 2 returns to its original shape, and the pressure of the human body on the first spring 61 disappears. Under its own elasticity, the first spring 61 returns to the state where it is separated from all three micro switches 51. The micro switches 51 return to their initial open state, and the controller immediately cuts off the power supply to the power system. At this time, even if the throttle button or other control components are accidentally touched, the vehicle cannot start or accelerate, effectively avoiding safety accidents caused by accidental operation after the person leaves the driver's seat, and improving the safety of electric vehicles during use.

[0042] Reference Figure 1 To facilitate maintenance personnel in inspecting the micro switch 51, multiple positioning blocks 41 are fixedly connected to the outer periphery of the mounting base 4. In this embodiment, the positioning blocks 41 are fan-shaped and there are six of them. The inner periphery of the mounting groove 3 is provided with positioning grooves 31 that cooperate with the six positioning blocks 41. Each positioning block 41 is detachably connected to the base 1 by connecting bolts 7. In this embodiment, the connecting bolts 7 adopt a countersunk head design, and the bolt holes penetrate the positioning block 41 and the base 1.

[0043] When installing the mounting base 4, the worker aligns the positioning block 41 on the mounting base 4 with the positioning groove 31 to complete the initial positioning. Then, the worker screws the connecting bolt 7 into the bottom of the base 1 and tightens it to ensure the stable installation of the mounting base 4 and the base 1. When the micro switch 51 malfunctions or the trigger 6 fails, the worker only needs to use a screwdriver or other tools to unscrew the connecting bolt 7 to remove the mounting base 4 from the mounting groove 3, thus enabling convenient inspection and replacement of the internal sensing components.

[0044] The implementation principle of a sensor seat in this application embodiment is as follows: When the driver sits on the seat during the use of the electric vehicle, the driver's own weight compresses the sponge layer 2 and causes deformation. The sponge layer 2 compresses the first spring 61 in the direction of the fixed seat 4. After being compressed, the first spring 61 undergoes elastic deformation and presses the micro switch 51. At this time, the micro switch 51 is turned on, and the controller receives the turn signal, allowing the driver to start the electric vehicle power system through the control components such as the throttle button.

[0045] When the driver leaves the seat, the weight of the human body above the sponge layer 2 disappears, the sponge layer 2 returns to its original shape, and the pressure of the human body on the first spring 61 disappears. Under its own elasticity, the first spring 61 returns to the state where it is separated from all three micro switches 51. The micro switches 51 return to their initial open state, and the controller immediately cuts off the power supply to the power system. At this time, even if the throttle button or other control components are accidentally touched, the vehicle cannot start or accelerate, effectively avoiding safety accidents caused by accidental operation after the person leaves the driver's seat, and improving the safety of electric vehicles during use.

[0046] Example 2

[0047] Reference Figure 4 The difference between this embodiment and embodiment 1 is that the trigger 6 includes a second spring 62 corresponding to a plurality of micro switches 51. In this embodiment, there are three second springs 62 and three micro switches 51. The second springs 62 are made of elastic metal material. Each second spring 62 is fixedly installed on the switch base 5 of the corresponding micro switch 51. The second spring 62 covers the corresponding micro switch 51. In its natural state, the second spring 62 and the corresponding micro switch 51 are in a non-contact state.

[0048] The implementation principle of Example 2 is as follows: When the driver sits down, the sponge layer 2 compresses multiple second springs 62, and the second springs 62 undergo elastic deformation and simultaneously touch the corresponding micro switch 51. When one of the second springs 62 fails due to elastic fatigue, the other second springs 62 and micro switches 51 can still work normally, reducing the risk of the entire sensing system being paralyzed due to the failure of a single component. At the same time, workers only need to replace a single second spring 62 and micro switch 51 to achieve maintenance, reducing maintenance costs.

[0049] Example 3

[0050] Reference Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that a connecting component 8 is provided at the connection between the trigger 6 and the switch base 5. The trigger 6 is detachably connected to the switch base 5 through the connecting component 8. In this embodiment, the trigger 6 is a first spring 61, and both ends of the first spring 61 are detachably connected to the switch base 5 through the connecting component 8.

[0051] When the trigger element 6 fails to work due to elastic fatigue or breakage, the maintenance personnel only need to remove the damaged trigger element 6 from the switch base 5 through the connecting assembly 8. This eliminates the need to replace the multiple switch bases 5 and trigger elements 6 on the fixed base 4 as a whole, thereby improving the efficiency of worker maintenance and reducing maintenance costs.

[0052] Reference Figure 5 and Figure 6 The connecting component 8 includes a connecting seat 81 fixedly mounted on the trigger 6. The connecting seat 81 and the switch seat 5 are provided with interconnecting connecting grooves 9. A connecting shaft 82 is rotatably connected inside the connecting groove 9. A stop 83 is fixedly connected to one end of the connecting shaft 82 to prevent the connecting shaft 82 from being over-inserted or over-extracted.

[0053] Reference Figure 5 and Figure 6Multiple elastic clips 84 are fixedly connected to one end of the connecting shaft 82 away from the stop block 83. The multiple elastic clips 84 are evenly distributed around the outer surface of the connecting shaft 82. In this embodiment, there are two elastic clips 84. Each elastic clip 84 has an integrally formed hook part 85. Each hook part 85 is provided with a transition slope 851 to facilitate insertion into the connecting groove 9. When the two elastic clips 84 are brought together, the area of ​​the two hook parts 85 spliced ​​together is smaller than the area of ​​the connecting groove 9. In the natural state, there is a gap between the two elastic clips 84. The hook part 85 extends out of the connecting groove 9 and abuts against the outer surface of the switch base 5.

[0054] The implementation principle of Example 3 is as follows: When disassembling the damaged trigger 6, the worker pinches multiple elastic clips 84 to make them contract inward under force, the hook part 85 disengages from the outer surface of the switch seat 5, then the connecting shaft 82 is pulled out from the connecting groove 9, and finally the worker lifts the connecting seat 81 upward to make it disengage from the switch seat 5, thus realizing the disassembly of the damaged trigger 6.

[0055] When installing the trigger 6, the worker first aligns the connecting seat 81 with the connecting groove 9 of the switch seat 5. Then, using the guiding effect of the transition slope 851, the connecting shaft 82 is inserted into the connecting groove 9. At this time, the elastic retaining strip 84 is in an inward contraction state. When the hook part 85 extends out of the connecting groove 9, the elastic retaining strip 84 opens outward by its own elasticity, so that the hook part 85 abuts against the outer surface of the switch seat 5. In this way, the new trigger 6 is installed and fixed to the switch seat 5. The setting of the connecting component 8 allows the worker to disassemble and assemble without the need for complicated tools, thus improving assembly efficiency.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
