[0040] Figures 1 to 3 Different cross-sectional views of the self-opening cover system 100 according to embodiments of the present application are schematically shown.

[0041] As Figures 1 to 3 shown, the self-opening cover system 100 comprises a cover 110, a cover support 120, and an operating device 130. The cover 110 is configured to cover an opening 310. The opening 310 is used to accommodate a part of a charging battery. The cover support 120 is configured to support the cover 110 and is provided with a socket 121. The operating device 130 is provided in the cover support 120 and is configured to drive the cover 110 to open the opening 310 when a guide pin 210 is inserted into the socket 121 and drive the cover 110 to cover the opening 310 when the guide pin 210 is withdrawn from the socket 121. The guide pin 210 is provided on the bottom of the charging battery.

[0042] In some embodiments, the operating device 130 comprises a motion direction conversion mechanism 131 configured to convert the insertion motion of the guide pin 210 in the socket 121 into the motion of the cover 110. For example, the motion direction conversion mechanism 131 can convert the vertical movement of the guide pin 210 in the socket 121 into the horizontal movement of the cover 110, so that the cover 110 can expose or cover the opening 310.

[0043] In some embodiments, the cover holder 120 is provided with at least two insertion holes 121, and at least two guide pins 210 are used to be inserted into the at least two insertion holes 121, respectively.

[0044] In some embodiments, the motion direction conversion mechanism 131 includes a guide sleeve 1311 provided in each insertion hole 121, and the guide sleeve 1311 is configured to move with the insertion movement of the guide pin 210 in the insertion hole 121. When the guide pin 210 is inserted into the insertion hole 121, the guide pin 210 abuts against the guide sleeve 1311 in the insertion hole 121 and forces the guide sleeve 1311 to move downward. In some embodiments, the guide pin 210 has a chamfered end 211 which can be inserted into an opening 1315 of the guide sleeve 1311 to realize the joint movement of the guide pin 210 and the guide sleeve 1311.

[0045] In some embodiments, the cover body 110 includes two half cover parts 111, and each half cover part 111 is provided with two motion direction conversion mechanisms 131. The two motion direction conversion mechanisms 131 are respectively arranged on both sides of the half cover part 111. The half cover part 111 can be made of rubber or any other suitable material. The two motion direction conversion mechanisms 131 located on the same side of the two half cover parts 111 share the same guide sleeve 1311 in the insertion hole 121. In some embodiments, two insertion holes 121 are provided, a guide sleeve 1311 is inserted into each insertion hole 121, and the guide sleeve 1311 connects the two motion direction conversion mechanisms 131. In some embodiments, the two motion direction conversion mechanisms 131 located on the same side of the two half cover parts 111 are symmetrically arranged with respect to the guide sleeve 1311.

[0046] In some embodiments, each motion direction conversion mechanism 131 further includes a rotating wheel 1312 and a rope belt 1313 around the rotating wheel 1312. The rotating wheel 1312 is arranged on the cover holder 120. For example, the rotating wheel 1312 is arranged on the cover holder 120 through a bearing 1314, and the rope belt 1313 can be formed of steel wire or any other suitable material. A first end of the rope belt 1313 is connected with the corresponding half cover part 111, and a second end is connected with a bottom end of the guide sleeve 1311. Specifically, the half cover part 111 has an inner side close to the other half cover part 111 and an outer side away from the other half cover part 111. The rotating wheel 1312 is arranged close to the outer side of the half cover part 111. The first end of the rope belt 1313 is connected with the inner side of the half cover part 111, and the second end of the rope belt 1313 is connected with the bottom end of the guide sleeve 1311 through the rotating wheel 1312.

[0047] In some embodiments, as Figure 4As shown, the cover bracket 120 includes two sliding rails 122 disposed on both ends of the cover bracket 120, and both ends of each half cover portion 111 are respectively slidably disposed on the two sliding rails 122. In some embodiments, both ends of each half cover portion 111 are slidably disposed on the two sliding rails 122 by sliding members. For example, the sliding members can be sliders or steel balls.

[0048] In some embodiments, each half cover portion 111 is provided with at least one reset member 140 for resetting the half cover portion 111.

[0049] In some embodiments, each half cover portion 111 is provided with two reset members 140 for resetting the half cover portion 111. Each reset member 140 includes a guide rod 141 and an elastic member 142 surrounding the guide rod 141. The first end of the guide rod 141 is fixedly connected to the inner side of the half cover portion 111, and the second end of the guide rod 141 passes through the outer side of the half cover portion 111. The second end of the guide rod 141 is provided with a nut for preventing the guide rod 141 from falling off the outer side of the half cover portion 111. When the two half cover portions 111 move away from each other, the second end of the guide rod 141 moves outward through the opening in the outer side of the half cover portion, and the elastic member 142 is compressed. For example, the elastic member 142 can be a spring.

[0050] According to another aspect of the present application, a battery case is provided. The battery case is disposed on an electric vehicle. Specifically, the battery case includes a case having an opening 310 for accommodating a battery, a cover 110 configured to cover the opening 310 of the case, a cover bracket 120 disposed on the case and configured to support the cover 110, and an operating device 130 configured to drive the cover 110 to open the opening 310 when the battery is placed into the case, and cover the opening 310 when the battery is removed from the case. In some embodiments, the cover bracket 120 can be integrally formed with the case of the battery case. Some electrical devices for electrically connecting the battery with the electric vehicle are disposed in the opening 310, which are omitted here for clarity.

[0051] In some embodiments, the cover bracket 120 is provided with at least two insertion holes 121, and the battery is provided with at least two guide pins 210 for being respectively inserted into the at least two insertion holes, so as to place the battery into the case.

[0052] According to another aspect of the present application, an electric vehicle is provided. The electric vehicle includes a vehicle body and a battery case disposed in the vehicle body.

[0053] Reference Figure 5 and Figure 6When the guide pin 210 of the battery (i.e., the fully charged battery) is inserted into the insertion hole 121, the guide pin 210 abuts against the guide sleeve 1311 and forces the guide sleeve 1311 to move downward. Since the first end of the rope belt 1313 is connected to the inner side of the half cover portion 111 and the second end of the rope belt 1313 is connected to the bottom end of the guide sleeve 1311 through the rotating wheel 1312, the guide sleeve 1311 drives the second end of the rope belt 1313 to move downward, and in turn, the first end of the rope belt 1313 to move outward, so the two half cover portions 111 move outward along the two sliding rails 122 with the first end of the rope belt 1313. Then, the opening 310 is opened, and the fully charged battery can be installed in the opening 310.

[0054] When the two half cover portions 111 move away from each other, the second end of the guide rod 141 moves outward through the opening on the outer side of the half cover portion 111, thereby compressing the elastic member 142.

[0055] When the battery is taken out, the guide pin 210 of the battery is pulled out of the insertion hole 121. The guide pin 210 no longer abuts against the guide sleeve 1311, so no force is applied to the rope belt 1313. Therefore, the two half cover portions 111 tend to move toward each other under the restoring force of the elastic member 142, and automatically cover the opening 310. Thus, when the battery is disassembled, rainwater or dust cannot enter the opening, which is beneficial to protect the electronic device and avoid the electronic device from aging.
