[0024] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented based on the technical solutions of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0025] like Figures 1 to 4As shown, an embodiment of the present invention provides an electric bicycle meter that combines hard and soft keycaps. The meter comprises a lower cover 1 and an upper cover 2 detachably connected to the upper side of the lower cover. A mainboard 3 is fixed within the lower cover 1. A plurality of key bodies 4 are disposed on the upper side of the mainboard 3. A soft keycap 5 is disposed on the upper side of the key bodies 4. The soft keycap 5 is preferably a silicone keycap, exhibiting excellent elasticity and automatically resetting upon being pressed. The soft keycap 5 comprises a base 51 disposed on the upper side of the circuit board 3 and a cap 52 connected to the base 51. The base 51 and cap 52 may be integrally formed. The caps 52 correspond to the key bodies 4 in a one-to-one manner, i.e., one cap 52 is disposed on the upper side of each key body 4. A hard keycap 6, preferably made of plastic, is sleeved over the upper end of some caps 52. The upper cover 2 has a plurality of through-holes 7 formed therein. The through-holes 7 are positioned to correspond to the caps 52 and the hard keycaps 6. Both the caps 52 and the hard keycaps 6 pass through the through-holes 7. Thus, the hard keycap 6 and the cap body 52 without the hard keycap 6 can be pressed from the upper side of the upper cover 2, and the pressure is applied to the key body 4 through the cap body 52. In addition, a display screen connected to the main board 3 is also provided on the upper cover 2 to display corresponding data.

[0026] To facilitate securing the motherboard 3, multiple support blocks 8 are provided at the bottom of the lower cover 1, and multiple undercuts 9 are provided on the sides of the lower cover 1. The motherboard 3 is positioned between the support blocks 8 and the undercuts 9. The support blocks 8 are preferably positioned around the upper side of the lower cover 1. In addition, to prevent deformation of the motherboard 3 during a pressing operation, some of the support blocks 8 can be positioned near the underside of the key body 4.

[0027] To enhance waterproofing, an upper potting layer 10 and a lower potting layer 11 are preferably provided on the upper and lower sides of the mainboard 3, respectively. The upper end of the key body 4 is exposed above the upper potting layer 10, so as not to affect the pressing of the key body 4. It should also be noted that after the upper potting layer 10 is provided, the base 51 is directly placed on the upper potting layer 10. When the upper cover 2 is fixed to the upper side of the lower cover 1, the upper cover 2 can exert a certain pressure on the base 51, preventing water from entering through the through hole 7.

[0028] The present embodiment of the utility model has three key bodies 4, namely the plus key, the minus key and the power key. Among them, it is preferred to set the hard key cap 6 on the upper end of the cap body 52 above the plus key and the minus key, so that the power key has a different tactile feel from the plus key and the minus key. When using, the keys can be distinguished by the tactile feel, which improves the user experience. The above-mentioned plus key and minus key are preferably set on both sides of the power key. For details, please refer to Figure 1 and Figure 2 Markings on the upper side of the hard keycap 6 and the cap body 52.

[0029] The hard keycap 6 of the embodiment of the present invention is preferably slidably connected to the inner side of the through hole 7, and a limiting portion 61 is provided at the lower end of the hard keycap 6. After assembly, the limiting portion 61 can prevent the hard keycap 6 from falling out of the through hole 7.

[0030] The lower cover 1 and the upper cover 2 of the present invention are preferably connected by snap fastening. Specifically, a plurality of slots 12 can be provided on the upper side of the lower cover 1, and a plurality of blocks 13 adapted to the slots 12 can be provided on the lower end of the upper cover 2.

[0031] A wire tube 14 is also provided on the lower side of the lower cover 1. The signal line between the main board 3 and the main controller of the electric assisted bicycle can pass through the wire tube 14. When the lower glue layer 11 is set, the gap between the signal line and the wire tube 14 will be sealed to ensure a good waterproof effect.

[0032] The above description is merely a preferred embodiment of the present invention. It should be noted that for those skilled in the art, any other aspects not specifically described are considered prior art or common knowledge. Improvements and modifications may be made without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
