[0030] Example 1

[0031] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a photovoltaic low-speed vehicle power domain controller, including a main component 100, a dustproof component 200, and a fixing component 300.

[0034] A dustproof component 200 is disposed on the outside of the controller housing 101, including a connecting strap 201 fixed to the outside of the controller housing 101. A dustproof cover 202 is fixed to the end of the connecting strap 201 away from the controller housing 101. A plug adapted to the wire interface 102 is also provided inside the dustproof cover 202. When the dustproof cover 202 is inserted into the wire interface 102, the plug is also inserted into the cell port of the wire interface 102, thereby further improving the protection effect of the wire interface 102. A connecting groove 203 is provided on the outside of the controller housing 101, and the dustproof cover 202 is movably connected to the inside of the connecting groove 203. A through hole 204 is provided on the inner side of the groove 203. A connecting rod 205 is slidably connected to the inner side of the through hole 204. One end of the connecting rod 205 is movably connected to the dust cover 202. An operating plate 206 is fixed on the outer side of the connecting rod 205. By moving the operating plate 206, the dust cover 202 can be easily pushed out of the connecting rod 205 and removed from the connecting groove 203 for use. It should be noted that a corresponding power interface is also provided on the wire interface 102 side of the controller housing 101. The power interface must be plugged in when in use, otherwise the controller cannot be used. Therefore, this part does not require dust protection.

[0035] The fixing component 300 is disposed on the outside of the controller housing 101, including a support base 301 fixed to the outside of the controller housing 101. The support base 301 is located below the wire interface 102 and will not affect the plugging and unplugging of the connector of the wire interface 102 in actual application. A pull plate 302 is slidably connected to the inside of the support base 301. A locking block 303 is fixed to the top of the pull plate 302 and a pulling member 304 is fixed to the bottom of the pull plate 302. A spring 305 is sleeved on the end of the pulling member 304. The pulling member 304, in cooperation with the spring 305, causes the connected pull plate 302 to move at the upper limit of the support base 301, so that the locking block 303 on the pull plate 302 can reinforce the dust cover 202.

[0036] Example 2

[0037] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the dustproof component 200 also includes a latching block 206a fixed to the top of the operating plate 206. The upper surface of the latching block 206a is designed in an arc shape for easy operation and use. A sliding hole 206b is provided on the inner top wall of the through hole 204. The operating plate 206 slides inside the sliding hole 206b. The sliding hole 206b is connected to the connecting groove 203 through the through hole 204. Since the latching block 206a is installed on the upper end of the operating plate 206, the connecting rod 205 can be operated easily through the latching block 206a.

[0039] The top of the controller housing 101 has an inner groove 206c. The through hole 204 communicates with the inner groove 206c through the sliding hole 206b. The latching block 206a is located inside the inner groove 206c. Since the inner groove 206c is located on the upper surface of the controller housing 101, and the latching block 206a is located in the inner groove 206c, this is beneficial to the protection of the latching block to a certain extent, and it is not easy to be accidentally touched.

[0040] A first magnet 202a is fixed to the outer side of the dust cover 202, and a second magnet 202b that cooperates with it is fixed to the inner wall of the connecting groove 203. Through the cooperation of the first magnet 202a and the second magnet 202b, the dust cover 202 can be easily fixed in the connecting groove 203 in the form of magnetic attraction. Both the first magnet 202a and the second magnet 202b are annular. One end of the connecting rod 205 slides on the inner side of the second magnet 202b. The first magnet 202a and the second magnet 202b adopt an annular design, which satisfies the magnetic attraction and fixation of the dust cover 202, and also allows one end of the connecting rod 205 to pass through the second magnet 202b and contact the dust cover 202, pushing it out of the connecting groove 203.

[0041] An arc-shaped groove 203a is provided in the connecting groove 203, and one end of the connecting strip 201 is located inside the arc-shaped groove 203a. By providing an arc-shaped groove 203a in the connecting groove 203, and having one end of the connecting strip 201 on the dust cover 202 inside the arc-shaped groove, the dust cover 202 can be easily magnetically fixed in the connecting groove 203, while ensuring a stable installation effect.

[0042] The pulling component 304 includes two pull rods 304a fixed to the bottom of the pull plate 302. One end of the pull rod 304a is fixed with a handle 304b. The U-shaped structure formed by the two symmetrical pull rods 304a and the handle 304b at the lower end of the pull plate 302 can be easily pulled from below the support base 301 to move the locking block 303.

[0043] The support base 301 has a first mounting groove 301a and a second mounting groove 301b on its outer side. The pull plate 302 slides inside the first mounting groove 301a. The two ends of the spring 305 are fixed to the first mounting groove 301a and the pull plate 302, respectively. One end of the pull rod 304a slides inside the second mounting groove 301b and is fixed to the handle 304b. The first mounting groove 301a allows for easy positioning of the spring 305 at the lower end of the pull plate 302, facilitating the pulling of the pull plate 302. The locking block 303 on the support base 301 secures the dust cover 202. The outer side of the dust cover 202 has a locking groove 202c. One end of the locking block 303 engages with the locking groove 202c. The locking block 303 on the support base 301 can easily secure the dust cover 202 through the locking groove 202c on the dust cover 202. It should be noted that when the dust cover 202 is snapped onto the wire interface 102, it will come into contact with the locking block 303 on the support base 301 because it is pushed in horizontally.

[0044] Limiting grooves 301c are provided on both sides of the inner wall of the first mounting groove 301a. The end of the pull plate 302 slides inside the limiting groove 301c. One end of the locking block 303 is inclined. Due to the setting of the limiting groove 301c in the first mounting groove 301a, the pull plate 302 can slide vertically up and down in the first mounting groove 301a of the support base 301. The limiting groove 301c has a limiting effect on the pull plate 302. When the pull plate 302 slides from top to bottom in the limiting groove 301c until it can no longer move, the locking block 303 separates and retracts into the first mounting groove 301a. This not only reduces some of the useless work done when operating the pull handle 304b, but also strengthens the protection of the spring 305 to a certain extent, preventing the pull plate 302 from continuously moving down and damaging the spring 305.

[0045] In use, first, the controller housing 101 is installed on the photovoltaic low-speed vehicle, and then the wiring is performed. During the wiring process, since the wire interface 102 is not dustproof, and the dust cover 202 is fixed in the connection groove 203 on the controller housing 101 by magnetic attraction, it will not block or hinder the insertion and removal of the connection wire connector on the wire interface 102 of the controller housing 101. After the wiring is completed, when dustproofing the temporarily unused wire interface 102, the operating plate 206 is moved by the latching block 206a and the lower connecting rod 205 is used to push the dust cover 202 out of the connection groove 203, and it can be folded into the wire interface 102 for protection.

[0046] After folding, the dust cover 202 is pushed horizontally into the wire interface 102 of the controller housing 101. During this process, the lower end of the dust cover 202 presses against the inclined part of the locking block 303 on the support base 301, causing the pull plate 302 connected to the locking block 303 to slide in the first mounting groove 301a of the support base 301. At the same time, the pull plate 302 moves down to compress the spring 305 until the dust cover 202 is inserted into the wire interface 102 and the locking groove 202c on the dust cover 202 corresponds to the position of the locking block 303. At this time, under the self-resetting effect of the spring 305, the pull plate 302 is pushed up, and the locking block 303 on the pull plate 302 automatically engages in the locking groove 202c of the dust cover 202, which enhances the stability of the dust cover 202 and makes it less susceptible to the impact of the low-speed photovoltaic vehicle, which could cause the dust cover 202 to fall off and lose its protective effect.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
