Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 As shown, the embodiment of the utility model provides a vehicle seat leaving alarm sensor assembly, the vehicle seat leaving alarm sensor assembly comprises a power battery 1, an ignition component 2, a combination meter 3, a controller 4 and a seat leaving signal output device, wherein:
[0030] The power battery 1 is used to provide power for the entire vehicle; the input end of the ignition component 2 is connected to the positive electrode of the power battery 1; the input end a of the instrument cluster 3 is connected to the output end of the ignition component 2, and the output end c of the instrument cluster 3 is connected to the negative electrode of the power battery 1; the input end e of the controller 4 is connected to the output end b of the instrument cluster 3, the input end d of the controller 4 is connected to the input end a of the instrument cluster 3, and the output end g of the controller 4 is connected to the negative electrode of the power battery 1; the seat leaving signal output device is used to output the driver's seat leaving signal, and the seat leaving signal output device is connected to the output end f of the controller 4, and the other end is connected to the negative electrode of the power battery 1.
[0031] Specifically, the vehicle seat leaving alarm sensor assembly provided in this embodiment is composed of a power battery 1, an ignition component 2, a combination instrument 3, a controller 4 and a seat leaving signal output device. The ignition component 2 is used by the driver to start or shut down the new energy vehicle and collect the ignition signal of the vehicle; the combination instrument 3 is used to display the handbrake switch of the handbrake position signal, the seat leaving signal, various instrument indicator lights in the car, the speedometer and tachometer signals and other information. The controller 4 is connected to the vehicle's seat leaving signal output device, the combination instrument 3, the power battery 1 and the ignition component 2 through wires, wherein the seat leaving signal output device automatically monitors whether the driver is in the vehicle seat leaving signal output device when the ignition component 2 is turned on. If the driver has left the seat for a long time, the seat leaving signal output device sends an alarm signal to the controller 4. After receiving the alarm signal from the seat leaving signal output device, the controller 4 will delay the signal and filter out the short-term alarm signal when the driver occasionally bounces on the bumpy road. Only after receiving the alarm signal from the seat leaving signal output device that lasts for a long time (such as 2 seconds or longer), the seat leaving alarm signal will be sent to the instrument cluster 3 to light up the seat leaving alarm indicator light on the instrument cluster 3. When the ignition component 2 is in the disconnected state (such as the key is pulled out or the ignition lock is in the ACC gear), the controller 4 is powered off and no longer works.
[0032] It should be specially explained here that the controller 4 in this embodiment is a conventional instrument in the prior art and does not involve any improvement to the control program. It is just a further use of the existing control program. The improvement of the car seat departure alarm sensor lies in the design circuit of the connection relationship between different electronic components, which is specially explained here.
[0033] In some preferred implementations, the seat leaving signal output device is configured as a plug-in switch 5, and the plug-in switch 5 is disposed in the seat belt slot.
[0034] In some preferred implementations, the seat leaving signal output device is configured as a pressure sensor, and the pressure sensor is disposed on the vehicle seat.
[0035] In some preferred implementations, a seat leaving warning indicator light 6 is provided in the combination instrument 3. When the seat leaving warning indicator light 6 is in an off state, when the seat leaving signal outputter outputs a driver leaving seat signal, the seat leaving warning indicator light 6 is in a lit state.
[0036] In some preferred implementations, the power battery 1 includes a storage battery 11 and a first fuse 12 connected in series, the positive electrode of the storage battery 11 is connected to the first fuse 12, and the negative electrode of the storage battery 11 is grounded.
[0037] In some preferred implementations, the ignition component 2 includes an ignition lock 21 and a second fuse 22 and a third fuse 23 connected at both ends of the ignition lock 21, the end of the second fuse 22 away from the ignition lock 21 is connected to the first fuse 12, and the end of the third fuse 23 away from the ignition lock 21 is connected to the input a terminal of the combination instrument 3.
[0038] In some preferred implementations, the voltage of the battery 11 is 0-24 V. In conventional use, a 12 V battery or a 24 V battery is generally used.
[0039] In some preferred implementations, the ignition lock 21 includes a LOCK gear, an ACC gear, an ON gear, an H gear, and a STA gear. When the ignition lock 21 is in the ON gear, the ignition lock 21 is in a power-on state.
[0040] In some preferred implementations, the controller 4 is a vehicle body controller.
[0041] Combination Figure 1 As shown, when the driver sits on the driver's seat, the seat leaving signal output device is set as the plug switch 5 as an example for detailed description. At this time, the contact of the plug switch 5 is pressed down and connected to the ground wire, and the potential of the wire 003 to the ground is 0V. After the driver turns the ignition component 2 to the ON position, the power battery 1 is preferably 12V in this embodiment, so the line 007 connected to the ignition component 2 has a voltage output of +12V; at this time, the +12V voltage passes through the third fuse 23 to supply power to the controller 4 and the combination meter 3. At this time, the plug switch 5 provides the detected 0V signal to the controller 4 through the wire 003. After delay processing, the controller 4 provides the processed seat leaving alarm sensor status signal (such as +12V) to the combination meter 3 through the wire 004, so that the seat leaving alarm indicator light 6 in the combination meter 3 is in an extinguished state.
[0042] When the driver leaves the driver's seat, the contact in the plug switch 5 pops up and is no longer connected to the ground wire, and the potential of the wire 003 to the ground is no longer 0V.
[0043] If the ignition lock 21 is in the ON position, line 007 of the ignition lock 21 has a +12V voltage output. At this time, the +12V voltage passes through the third fuse 23 to power the controller 4 and the instrument cluster 3. At this time, the plug switch 5 will detect that the signal is no longer 0V and provide it to the controller 4 through the wire 003. After processing, the controller 4 will provide the processed seat departure alarm sensor status signal (such as OV) to the instrument cluster 3 through the wire 004, so that the seat departure alarm indicator light 6 in the instrument cluster 3 is in a lit state.
[0044] If the ignition lock 21 is no longer in the ON position (such as turned to the ACC position or LOCK position) or the ignition key is pulled out, the output voltage of line 007 of the ignition lock 21 is 0V, the power supply of the controller 4 and the instrument cluster 3 also becomes 0V, the controller 4 and the instrument cluster 3 stop working, and the seat departure warning indicator light 6 in the instrument cluster 3 is off.
[0045] The vehicle seat departure warning sensor assembly in the embodiment of the utility model has a simple structure and an adjustable delay. The controller adopts an existing vehicle body controller and has strong adaptability. It can be easily matched with different vehicle combination instruments, eliminating the phenomenon that the vehicle seat departure warning sensor indicator light is frequently lit due to occasional bouncing when the driver is on a bumpy road.
[0046] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
