As shown in FIGS. 1 to 3, the self-opening cover system 100 includes a cover body 110, a cover support 120, and an operation device 130. The cover body 110 is configured to cover an opening 310. The opening 310 is to accommodate a portion of a charging battery. The cover support 120 is configured to support the cover body 110 and provided with an inserting hole 121. The operation device 130 is disposed in the cover support 120 and configured to drive the cover body 110 to uncover the opening 310 when a guide pin 210 is inserted into the inserting hole 121 and to cover the opening 310 when the guide pin 210 is withdrawn from the inserting hole 121. The guide pin 210 is disposed on a bottom of the charging battery.
In some embodiments, the operation device 130 includes a movement direction translation mechanism 131 configured to translate an insertion movement of the guide pin 210 in the inserting hole 121 into a movement of the cover body 110. For example, the movement direction translation mechanism 131 may translate a vertical movement of the guide pin 210 in the inserting hole 121 into a horizontal movement of the cover body 110 so that the cover body 110 can uncover or cover the opening 310.
In some embodiments, the cover support 120 is provided with at least two inserting holes 121, and at least two guide pins 210 are provided for inserting into the at least two inserting holes 121 respectively.
In some embodiments, the movement direction translation mechanism 131 includes a guide sleeve 1311 disposed in each inserting hole 121, and the guide sleeve 1311 is configured to move with the insertion movement of the guide pin 210 in the inserting hole 121. When the guide pin 210 is inserted into the inserting hole 121, the guide pin 210 abuts against the guide sleeve 1311 in the inserting hole 121 and forces the guide sleeve 1311 to move downwards. 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 achieve a common movement of the guide pin 210 and the guide sleeve 1311.
In some embodiments, the cover body 110 includes two half cover portions 111, and each half cover portion 111 is provided with two movement direction translation mechanisms 131. The two movement direction translation mechanisms 131 are respectively disposed at two sides of the half cover portion 111. The half cover portion 111 may be made of rubber or any other suitable materials. Two movement direction translation mechanisms 131 at a same side of the two half cover portions 111 share a same guide sleeve 1311 in the inserting hole 121. In some embodiments, there are two inserting holes 121, and each inserting hole 121 is inserted with a guide sleeve 1311, and the guide sleeve 1311 is connected with two movement direction translation mechanisms 131. In some embodiments, the two movement direction translation mechanisms 131 at the same side of the two half cover portions 111 are symmetrically arranged with respect to the guide sleeve 1311.
In some embodiments, each movement direction translation mechanism 131 further includes a wheel 1312 and a string strip 1313 surrounding the wheel 1312. The wheel 1312 is disposed on the cover support 120. For example, the wheel 1312 is disposed on the cover support 120 through a bearing 1314, and the string strip 1313 may be formed by a steel wire or any other suitable materials. The string strip 1313 has a first end connected with a corresponding half cover portion 111 and a second end connected with a bottom end of the guide sleeve 1311. Specifically, the half cover portion 111 has an inner side close to another half cover portion 111 and an outer side far away from another half cover portion 111. The wheel 1312 is disposed close to the outer side of the half cover portion 111. The first end of the string strip 1313 is connected with the inner side of the half cover portion 111, and the second end of the string strip 1313 is connected with the bottom end of the guide sleeve 1311 through the wheel 1312.
In some embodiments, as shown in FIG. 4, the cover support 120 includes two sliding rails 122 disposed on two ends of the cover support 120, and two ends of each half cover portion 111 are slidably disposed on the two sliding rails 122 respectively. In some embodiments, two ends of each half cover portion 111 are slidably disposed on the two sliding rails 122 by a sliding member. For example, the sliding member may be a sliding block or a steel ball.
In some embodiments, each half cover portion 111 is provided with at least one restoration component 140 for restoring the half cover portion 111.
In some embodiments, each half cover portion 111 is provided with two restoration components 140 for restoring the half cover portion 111. Each restoration component 140 includes a guide rod 141 and an elastic member 142 surrounding the guide rod 141. A first end of the guide rod 141 is fixedly connected with the inner side of the half cover portion 111, and a 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 screw cap for preventing the guide rod 141 from falling from the outer side of the half cover portion 111. When the two half cover portions 111 are moved away from each other, the second end of the guide rod 141 move outwards through an opening in the outer side of the half cover portion 111, and the elastic member 142 is compressed. For example, the elastic member 142 may be a spring.
According to another aspect of the present disclosure, a battery container is provided. The battery container is disposed on an electric vehicle. Specifically, the battery container includes: a housing having the opening 310 for accommodating a battery, the cover body 110 configured to cover the opening 310 of the housing, the cover support 120 disposed on the housing and configured to support the cover body 110, and the operation device 130 configured to drive the cover body 110 to uncover the opening 310 when the battery is placed into the housing and to cover the opening when the battery is removed from the housing. In some embodiments, the cover support 120 may be integratedly formed with the housing of the battery container. Some electric devices for electrically connecting the battery with the electric vehicle are disposed in the opening 310, which are omitted herein for clarity.
In some embodiments, the cover support 120 is provided with at least two inserting holes 121, and at least two guide pins 210 are provided on the battery for inserting into the at least two inserting holes respectively, so as to place the battery into the housing.
According to another aspect of the present disclosure, an electric vehicle is provided. The electric vehicle includes a vehicle body and the battery container disposed in the vehicle body.
With reference to FIGS. 5 and 6, with the insertion of the guide pin 210 of the battery (i.e., a fully charged battery) in the inserting hole 121, the guide pin 210 abuts against the guide sleeve 1311 and forces the guide sleeve 1311 to move downwards. As the first end of the string strip 1313 is connected with the inner side of the half cover portion 111, and the second end of the string strip 1313 is connected with the bottom end of the guide sleeve 1311 through the wheel 1312, the guide sleeve 1311 drives the second end of the string strip 1313 to move downwards, and thus drives the first end of the string strip 1313 to move outwards, thus the two half cover portions 111 move outwards with the first end of the string strip 1313 along the two sliding rails 122. Then, the opening 310 is opened, and the fully charged battery can be installed in the opening 310.
When the two half cover portions 111 moves away from each other, the second end of the guide rod 141 passes through the opening in the outer side of the half cover portion 111 and moves outwards, so that the elastic member 142 is compressed.
When removing the battery, the guide pin 210 of the battery is withdrawn from the inserting hole 121. The guide pin 210 does not abut against the guide sleeve 1311 again, and thus no force is applied to the string strip 1313. As a result, the two half cover portions 111 trend to move towards each other under the restoring force of the elastic element 142, and cover the opening 310 automatically. Therefore, rain or dust cannot enter the opening when removing the battery, which is beneficial to protect electronic devices and avoid aging of electronic devices.
