DETAILED DESCRIPTION
[0023] In order to make the purpose, technical scheme and advantages of the utility model more clear and apparent, the utility model is further described in detail below in combination with specific embodiments and with reference to the drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0024] It is understood that the above description is only exemplary and is not intended to limit the scope of the utility model.
[0025] Some embodiments of the utility model provide a handle waterproof switch assembly, which is described below in combination with the drawings.
[0026] Embodiment 1
[0027] In combination with Figures 1-4 The utility model provides a handle waterproof switch assembly, which comprises a handle assembly 100 and a waterproof mechanism 200 arranged outside the handle assembly 100. The waterproof mechanism 200 is arranged outside the handle assembly 100 to provide waterproof protection for the handle assembly 100 and also provide a constant temperature and draining operation space for the user's hand.
[0028] The handle assembly 100 comprises a handlebar cross pipe 110 mounted on an electric vehicle handle, a switch seat 130 arranged on the handlebar cross pipe 110, and a speed regulating handle 120 movably mounted on the handlebar cross pipe 110.
[0029] The waterproof mechanism 200 comprises a reinforcing ring buckle 210, an upper protective sleeve 220 mounted on one end of the reinforcing ring buckle 210, a lower protective sleeve 230 mounted on the other end of the reinforcing ring buckle 210, a constant temperature assembly 250 arranged in the inner cavity of the lower protective sleeve 230, and a plurality of cushion blocks 240 mounted on the inner wall of the lower protective sleeve 230.
[0030] The cushion blocks 240 are made of rubber material.
[0031] With the increasingly mature assembly process between the electric vehicle switch handle and the speed regulating handle, the waterproof performance is also improved. However, the assembled handle is exposed for a long time, which is affected by high temperature, low temperature, and repeated influences. The handle shell will accelerate aging, and the handle assembly shell gap will expand, which will cause rainwater to enter.
[0032] The assembly provides waterproof blocking for the switch seat 130 and the speed regulating handle 120 along the direction of vehicle travel by arranging the reinforcing ring buckle 210, the upper protective sleeve 220, and the lower protective sleeve 230 outside the switch seat 130 and the speed regulating handle 120.
[0033] The multiple pads 240 set on the inner wall of the lower sheath 230 can be used to assemble and protect the combined first insulation shell 251 and second insulation shell 254. At this time, the combined first insulation shell 251 and second insulation shell 254 can be suspended. When the user's right hand is inserted from the bottom of the rubber sleeve 270, the water droplets on the user's hand can be absorbed by the water-absorbing layer on the surface of the rubber sleeve 270 and its top, until the wastewater is rotated by the safe operating speed control handle 120.
[0034] As the user's hands heat up inside the first insulation shell 251 and the second insulation shell 254, the steam generated by the heat will be discharged upwards through the heat dissipation hole 252. Under the influence of the airflow passively introduced by the vehicle's movement, the steam can be quickly vented, and the user's hands can be dried after the water droplets are drained. This can effectively improve the user's comfort and reduce the aging of the speed control handle 120 and the switch base 130.
[0035] Example 2:
[0036] Combination Figure 3 and Figure 4 As shown, based on Embodiment 1, the constant temperature component 250 includes a first insulation shell 251 and a second insulation shell 254.

[0038] The top of the first insulation shell 251 and the second insulation shell 254 are provided with heat dissipation holes 252, and the bottom of the first insulation shell 251 and the second insulation shell 254 are provided with drainage holes 253.
[0039] Preferably, the first insulation shell 251 and the second insulation shell 254 are pre-installed in the inner cavity of the lower sleeve 230. At this time, the multiple pads 240 fixed on the inner wall of the lower sleeve 230 can fasten the pre-installed first insulation shell 251 and the second insulation shell 254. The first insulation shell 251 and the second insulation shell 254, which are pre-installed and welded to form a sleeve structure, can provide constant temperature protection for the user's right hand. The lower sleeve 230, which is set outside the heat dissipation hole 252, provides a discharge channel for hot steam and water vapor, while preventing rainwater from entering the inner cavity of the first insulation shell 251 and the second insulation shell 254.
[0040] Example 3:
[0041] Combination Figures 2-4 As shown, based on Embodiment 1, an end cover 260 and a rubber sleeve 270 installed on the inner wall of the end cover 260 are provided in the grooves at the bottom of the first insulation shell 251 and the second insulation shell 254.
[0042] The end cover 260 is made of silica gel material, and the surface of the end cover 260 is coated with an anti-abrasion coating;
[0043] The rubber sleeve 270 is a lengthened rubber sleeve as a whole, and the rubber sleeve 270 is funnel-shaped from the lower end to the top end; the surface of the rubber sleeve 270 is provided with a water absorption layer.
[0044] Preferably, the upper half of the rubber sleeve 270 is provided with a water absorption layer according to the use requirement, and the lower half of the rubber sleeve 270 is provided with a waterproof layer; and the end cover 260 and the rubber sleeve 270 are vertically downward in the initial state.

[0046] The plug rod installed at one end of the locking nut 290 is installed in the booster head 280.
[0047] Preferably, aerogel is arranged in the inner wall of the first heat preservation shell 251 and the second heat preservation shell 254, so as to improve the efficiency of drying the wet right hand of the user by utilizing the characteristics of the super-fine pores, low density and low thermal conductivity of the aerogel.
[0048] The booster head 280 and the locking nut 290 are clamped by the first heat preservation shell 251 and the second heat preservation shell 254 after installation, and the other end of the booster head 280 is installed in the hole away from the end of the switch base 130 of the handlebar cross pipe 110; at this time, the horizontally arranged constant temperature assembly 250 as a whole can be kept stable during use.
[0049] The working principle and use process of the utility model are as follows: the handlebar cross pipe 110 is installed on the handle of the electric vehicle faucet in advance; at this time, the reinforcing ring buckle 210 is fixed to the outer end of the switch base 130, and the upper protective sleeve 220 which is firstly sleeved outside the handle needs to be fixed to the left end of the reinforcing ring buckle 210; then the lower protective sleeve 230 is installed on the groove outside the reinforcing ring buckle 210; at this time, the exposed slot of the lower protective sleeve 230 is inclined at an angle of forty-five degrees to the ground; and the first heat preservation shell 251 and the second heat preservation shell 254 are assembled in the inner cavity of the lower protective sleeve 230 through the booster head 280 and the locking nut 290; at this time, the rectangular slot formed at the bottom of the first heat preservation shell 251 and the second heat preservation shell 254 is vertically downward.
[0050] When the electric vehicle is used in rainy season, the user needs to put the right hand into the port of the end cover 260, at this time the user's right hand needs to squeeze into the inner cavity of the first heat preservation shell 251 and the second heat preservation shell 254 from the inside of the rubber sleeve 270, and the water absorption layer arranged on the rubber sleeve 270 can absorb the water droplets on the user's hand, and under the action of elastic contraction, the end of the top of the rubber sleeve 270 will be finally contracted on the user's wrist, when the control speed handle 120 is rotated, the combined first heat preservation shell 251 and the second heat preservation shell 254 can be rotated in the inner cavity of the lower sheath 230.
[0051] With the continuous warming of the user's hand in the relatively sealed environment, the hand hot steam can be discharged upward from the heat dissipation hole 252 at the top of the first heat preservation shell 251 and the second heat preservation shell 254, and the exposed gap between the switch seat 130, the first heat preservation shell 251 and the second heat preservation shell 254 can provide guidance for the airflow generated by the vehicle driving, and finally the user's right hand can be quickly air dried, and part of the water droplets falling from the user's arm can also be discharged outward from the water draining hole 253.
