[0031] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0032] like Figures 1-6 As shown, this utility model embodiment provides a control instrument for an electric bicycle. The instrument is installed on the handlebars of the electric bicycle and includes a housing 100, a main circuit board 200 and a keypad 300 disposed inside the housing 100, a display screen 400 and control buttons 500 disposed outside the housing 100. The keypad 300 and the display screen 400 are electrically connected to the main circuit board 200.

[0033] Reference Figures 3-6 The outer casing 100 has a keypad mounting slot, and the keypad 300 is fixedly installed in the keypad mounting slot. The keypad 300 has a plurality of key contacts 310. A cover plate 600 is provided at the slot opening outside the keypad mounting slot. The cover plate 600 has holes 610 corresponding to each key contact 310. An elastic sealing body 620 that contacts the corresponding key contact 310 is provided in the hole 610. The control button 500 is installed outside the cover plate 600 and can trigger the corresponding key contact 310 through each elastic sealing body 620.

[0034] In some embodiments, reference Figure 3 and Figure 4 Each button contact 310 is a convex column protruding towards one side of the elastic sealing body 620. The elastic sealing body 620 includes an outer ring portion 621, an inner ring portion 622, an annular connecting portion 623 located between the inner ends of the outer ring portion 621 and the inner ring portion 622, and a sealing end 624 located at the outer end of the inner ring portion 622. The outer ring portion 621 is sealed in the groove 610, the button contact 310 is inserted into the inner ring portion 622, and the sealing end 624 of the inner ring portion 622 protrudes out of the outer side of the cover plate 600 and contacts the control button 500.

[0035] The elastic seal 620 adopts an outer ring 621 and an inner ring 622 design. The outer ring 621 is fixed in the groove 610, and the button contact 310 is inserted into the inner ring 622. This not only seals the groove 610, but also allows each button contact 310 to better engage with the elastic seal 620. At the same time, it increases the pressure and rebound stroke of the elastic seal 620 to meet the requirements of a larger button stroke.

[0036] Optionally, the inner wall of the groove 610 near the keypad 300 is provided with a support member 611 located within the inner end of the elastic seal 620. The outer ring portion 621 of the elastic seal 620 is provided with a support ring 625, which is used to press the outer ring portion 621 against the inner wall of the groove 610, thus facilitating the fixation of the elastic seal 620 within the groove 610.

[0037] In some embodiments, reference Figure 1 , Figure 5 and Figure 6 The button contact 310 includes an upshift button contact 310, a downshift button contact 310, and a switch button contact 310.

On the inner side of the shift button 510, on both sides of the hinged portion, are respectively provided an upshift trigger protrusion 511 and a downshift trigger protrusion 512. The upshift trigger protrusion 511 abuts against the sealing end 624 corresponding to the upshift button contact 310, and the downshift trigger protrusion 512 abuts against the sealing end 624 corresponding to the downshift button contact 310. When the upshift button 510 touches the upshift button contact 310 via the upshift trigger protrusion 511, it controls the electric bicycle to shift up; when the upshift button 510 touches the downshift button contact 310 via the downshift trigger protrusion 512, it controls the electric bicycle to shift down.

[0040] The switch button 520 is hinged to the outside of the cover plate 600. On the inner side of the hinge, on both sides of the hinged portion, there are switch trigger protrusions 521 and positioning protrusions 522. The switch trigger protrusion 521 abuts against the sealing end 624 corresponding to the contact 310 of the switch button 520, and the positioning protrusion 522 abuts against the outer side of the cover plate 600. When the switch trigger protrusion 521 touches the contact 310 of the switch button 520, it can control the instrument switch.

[0041] This application provides a keypad mounting slot within the housing 100, with the slot opening sealed by a cover plate 600. The cover plate 600 also has a slot 610, within which an elastic sealing body 620 is installed. This not only provides a waterproof seal but also, when the control button 500 is pressed, the elastic sealing body 620 triggers the button contact 310 on the keypad 300, thus activating the button. Therefore, compared to existing technologies, the control button 500 of this application can be a hard button, increasing the button travel while maintaining waterproofness, resulting in a better tactile experience.

[0042] In some embodiments, reference Figure 2The control instrument for the electric bicycle also includes an external wiring port 700, which is located on the housing 100 and electrically connected to the main circuit board 200, so that it can be connected to the controller of the electric bicycle through the external wiring port 700.
