Description

Technical Field

[0001] The utility model relates to the technical field of electric three-wheeled sanitation vehicles, in particular to an induction pad for an electric three-wheeled sanitation vehicle. Background Art

[0002] As my country has fully launched the work of sorting urban and rural domestic waste, a large amount of waste generated every day needs to be collected and transported. Electric three-wheeled sanitation vehicles have become an indispensable tool because of their convenience and practicality. Domestic waste in rural areas needs to be collected door-to-door. Due to the special nature of their work, sanitation workers need to get on and off the vehicle frequently, which leads to sanitation workers generally leaving the vehicle without turning off the car key, pulling the handbrake, or shifting to neutral. Once the vehicle's speed control handle (accelerator) fails, the electric three-wheeled sanitation vehicle will lose control, start on its own and run wildly, causing terrible traffic accidents.

[0003] According to the research on various brands of electric three-wheeled sanitation vehicles on the market, the loss of control of electric three-wheeled sanitation vehicles when no one is around is mainly caused by the failure of the speed control handle (throttle), which causes the electric three-wheeled sanitation vehicle to be in the power-on acceleration state, causing the vehicle to lose control. Common causes of speed control handle (throttle) failure: 1. The speed control handle (throttle) is flooded during rainy days, causing a short circuit in the internal circuit of the speed control handle (throttle); 2. After long-term use of the speed control handle (throttle), dust and dirt are embedded in the gap of the speed control handle (throttle), causing the speed control handle (throttle) to be unable to be completely reset; 3. After long-term use of the speed control handle (throttle), the internal spring force fails and cannot be reset; 4. The speed control handle (throttle) is exposed to the sun for a long time, deformed by high temperature, and cannot be reset; 5. The shed of the electric three-wheeled sanitation vehicle is struck by lightning, and the speed control handle (throttle) on the vehicle is damaged.

[0004] At present, all electric three-wheel sanitation vehicle manufacturers require drivers to turn off the car key, tighten the handbrake, and shift into neutral before getting off the vehicle. This is a safety protection measure set by the manufacturer for the vehicle; however, in real life, due to the special nature of their work, sanitation workers generally do not turn off the car key, pull the handbrake, or shift into neutral when getting on and off the vehicle. Once the speed control handle (accelerator) fails, all the vehicle safety protection measures set by the manufacturer will become invalid. In order to prevent the vehicle from losing control, starting up and running wildly due to the speed control handle (accelerator) failure when the electric three-wheel sanitation vehicle is unmanned, we propose an electric three-wheel sanitation vehicle induction pad. Utility Model Content

[0005] The utility model aims to provide an induction pad for an electric three-wheeled sanitation vehicle to solve the above-mentioned deficiencies in the technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: an electric three-wheeled sanitation vehicle induction pad, comprising a induction pad formed by sewing an upper leather layer and a lower leather layer, a membrane pressure switch is provided between the upper leather layer and the lower leather layer, and a signal line on the membrane pressure switch is connected in series to the positive line connecting the speed control handle and the controller.

[0007] Furthermore, the membrane pressure switch is a flexible membrane pressure sensing switch, and the membrane pressure switch is normally in an off state.

[0008] Furthermore, a groove body adapted to a membrane pressure switch is provided on corresponding surfaces of the upper leather layer and the lower leather layer, the membrane pressure switch is adapted in the groove body of the lower leather layer, and the corresponding groove body of the upper leather layer does not contact the membrane pressure switch.

[0009] Furthermore, a comfort layer is sewn on the bottom of the sensing pad.

[0010] Furthermore, the upper leather layer, the membrane pressure switch, the lower leather layer and the comfort layer are arranged and installed in sequence from top to bottom on the driving seat of the electric three-wheeled sanitation vehicle.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0020] Example 1

[0021] like Figure 1-2 As shown, the utility model provides a technical solution: an electric three-wheel sanitation vehicle induction pad, comprising a induction pad 7 formed by sewing an upper leather layer 1 and a lower leather layer 2, a membrane pressure switch 3 is provided between the upper leather layer 1 and the lower leather layer 2, and a signal line 4 on the membrane pressure switch 3 is connected in series to the positive line connecting the speed control handle and the controller.

[0022] Example 2

[0023] like Figure 1-2As shown, the membrane pressure switch 3 is a flexible membrane pressure sensing switch, and the membrane pressure switch 3 is normally in a disconnected state. The use of a flexible membrane pressure sensing switch can reduce the probability of damage to the membrane pressure switch 3 after being compressed and deformed, thereby increasing the service life of the membrane pressure switch 3.

[0024] A groove 5 adapted to the membrane pressure switch 3 is opened on the corresponding surfaces of the upper leather layer 1 and the lower leather layer 2. The membrane pressure switch 3 is adapted in the groove 5 of the lower leather layer 2, and the corresponding groove 5 of the upper leather layer 1 does not contact the membrane pressure switch 3. The membrane pressure switch 3 is adapted in the groove 5 to ensure uniformity of pressure and improve service life. The groove 5 of the upper leather layer 1 does not contact the membrane pressure switch 3 to avoid the membrane pressure switch 3 entering a closed state after placing objects or lighter items such as clothing, which may cause accidental startup.

[0025] A comfort layer 6 is sewn to the bottom of the sensing pad 7, and the comfort layer 6 can be a sponge pad or a rubber pad.

[0026] The upper leather layer 1, the membrane pressure switch 3, the lower leather layer 2 and the comfort layer 6 are arranged and installed on the driving seat of the electric three-wheeled sanitation vehicle in sequence from top to bottom, and then the installation is completed and put into use.

[0027] Working principle: The induction pad 7 is installed on the driver's seat of the electric three-wheeled sanitation vehicle. The wiring harness of the membrane pressure switch 3 built into the induction pad 7 is connected in series to the positive line connecting the vehicle's speed handle (throttle) and the controller. When the human body touches the upper leather layer 1, the upper leather layer 1 is deformed by pressure. At this time, the membrane pressure switch 3 receives the pressure signal, the membrane pressure switch 3 is closed, and the speed handle (throttle) circuit is energized. At this time, the electric three-wheeled sanitation vehicle can start normally. When the human body leaves the upper leather layer 1, the pressure on the upper leather layer 1 disappears. At this time, the pressure signal of the membrane pressure switch 3 disappears, and the membrane pressure switch 3 is in a disconnected state. At this time, the speed handle (throttle) circuit is disconnected, and the electric three-wheeled sanitation vehicle cannot be started.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
