[0025] The utility model is now further described with reference to the accompanying drawings.

[0026] like Figures 1 to 9 As shown, a cushion seat sensing device comprises a base 1, an elastic cushion seat, a fixing seat 3, a micro switch 2, a spring 4, and a movable pressure plate 6. The base 1 is used to be installed on an electric bicycle, and the elastic cushion seat is covered on the base 1. The top of the base 1 is provided with a sensing slot 15, and the bottom of the sensing slot 15 is provided with three fixing holes 11, and the fixing holes 11 are through holes. The fixing seat 3 is detachably mounted on the fixing holes 11, and the micro switch 2 and the spring 4 are both mounted on the fixing seat 3, and the movable pressure plate 6 is movably inserted in the sensing slot 15 and is located above the spring 4 and the micro switch 2. The spring 4 pushes the movable pressure plate 6 against the elastic cushion seat. When a person sits on the elastic cushion seat, the movable pressure plate 6 will be driven to move downward through the elastic cushion seat, and the movable pressure plate 6 will press on the micro switch 2, and the micro switch 2 will be turned on. At this time, the throttle of the electric bicycle can be used normally. When the person leaves the elastic cushion seat, the movable pressure plate 6 automatically moves away from the micro switch 2 under the action of the spring 4, and the micro switch 2 is turned off, and the throttle is invalid at this time. The spring 4 and the micro switch 2 can ensure sensitivity, reliability and stability, and long service life. The fixing seat 3 is detachable, and maintenance is convenient when a failure occurs. It only needs to remove the fixing seat 3 and replace the spring 4 and the micro switch 2, which greatly improves the efficiency of maintenance and reduces the cost of maintenance. The cost of the spring 4 and the micro switch 2 is also lower than that of the contact switch.

[0027] In actual use, one micro switch 2 and a fixing seat 3 can be set. However, in order to improve the sensitivity and range of detection and avoid the situation where a person sitting in the front or back position of the elastic seat cushion causes normal detection, two fixing seats 3 and two micro switches 2 can be set or three fixing seats 3 and three micro switches 2 can be set. More micro switches 2 and fixing seats 3 can also be set.

[0028] A switch slot 35 is provided at the center of the fixing seat 3 , and the micro switch 2 is installed in the switch slot 35 . The switch slot 35 matches the micro switch 2 , can effectively fix the micro switch 2 , and is convenient for replacement of the micro switch 2 .

[0029] The outer surface of the fixing seat 3 is provided with three fixing sheets 31 and three fixing blocks 32 in an annular array, and the fixing sheets 31 and the fixing blocks 32 are arranged alternately and are respectively located at the two ends of the fixing seat 3. The fixing hole 11 is provided with three through grooves 111 in an annular array, and the through grooves 111 match the fixing blocks 32 and correspond one to one. When installing, align the fixing blocks 32 of the fixing seat 3 with the through grooves 111, and then insert the fixing seat 3, so that the fixing sheet 31 is against the base 1, and then rotate the fixing seat 3 so that the fixing block 32 is stuck to one end of the fixing hole 11, and then the fixing sheet 31 and the fixing block 32 are respectively pressed against the two ends of the fixing hole 11, so that the fixing seat 3 is fixed and the removal of the fixing seat 3 is convenient.

[0030] In order to prevent the fixing seat 3 from rotating freely, two positioning blocks 13 are provided in a circular array on the base 1, and a positioning protrusion 131 is provided on the positioning block 13, and a positioning groove 321 matching the positioning protrusion 131 is provided on the fixing block 32. When the fixing seat 3 is rotated, the positioning protrusion 131 is inserted into the positioning groove 321, thereby realizing the positioning of the fixing seat 3, and the fixing seat 3 cannot rotate freely, thereby preventing the fixing seat 3 from falling off during use, causing the throttle to be unable to be used normally, and improving the overall reliability and stability.

[0031] When the elastic force of a partially elastic cushion seat is large or the force of the spring 4 is small, multiple springs 4 can be installed on a fixed seat 3. In order to facilitate the fixation of the spring 4, two concentrically arranged first spring grooves 33 and second spring grooves 34 are provided on the fixed seat 3. When two springs 4 are used, the diameters of the two springs 4 are different to achieve concentric installation.

[0032] The movable pressing plate 6 is provided with three upper pressing grooves 61 corresponding to the fixing seat 3 one by one, and one end of the spring 4 is against the upper pressing groove 61. The upper pressing groove 61 can also realize the positioning of the end of the spring 4.

[0033] In order to protect the leads of the micro switch 2, the top of the base 1 is provided with a fourth wiring groove 14 and a third wiring groove 12. The fourth wiring groove 14 is located at one end of the base 1 and is arranged opposite to the fixing hole 11. Two third wiring grooves 12 are provided, which are respectively located between two adjacent fixing holes 11, and a wire blocking plate 121 is provided in the third wiring groove 12. The wire blocking plate 121 limits the leads in the third wiring groove 12. The movable pressing plate 6 is provided with a plurality of second wiring grooves 62, which are arranged opposite to the third wiring groove 12 and the fourth wiring groove 14 to avoid interference and do not affect the travel of the movable pressing plate 6 moving down the mountain.

[0034] The fixing seat 3 is further provided with a first wiring groove 36 , which is communicated with the switch groove 35 .

[0035] The lead wire of the micro switch 2 passes through the first wiring groove 36 and enters the third wiring groove 12 and the fourth wiring groove 14, and then is connected to the controller in the belly of the vehicle.

[0036] During installation, first install the movable pressure plate 6 into the sensing slot 15, then install the elastic cushion seat, then install the spring 4 and the micro switch 2 into the spring slot and the switch slot 35 respectively, and then install the fixing seat 3 into the fixing hole 11. The assembly is convenient, simple, efficient and low-cost.

[0037] During replacement, rotate the fixing base 3 to align the fixing block 32 with the through slot 111, then pull out the fixing base 3 downward, replace the spring 4 and the micro switch 2 as needed, then insert the fixing base 3 with the spring 4 and the micro switch 2 into the fixing hole 11, and rotate the fixing base 3 so that the positioning protrusion 131 is inserted into the positioning slot 321.

[0038] The movable pressure plate cooperates with no less than one fixed seat, micro switch and spring to effectively ensure the force-bearing area, reduce the influence of the softness and hardness of the elastic seat cushion, effectively transmit force, and ensure sensitivity, stability and reliability.

[0039] It can be used on two-wheeled, three-wheeled, four-wheeled electric vehicles, electric motorcycles, fuel motorcycles and electric vehicles.

[0040] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the claims of the present invention.
