Description

Technical Field

[0001] The utility model relates to a lift and a battery swap station. Background Art

[0002] Electric vehicles have the advantages of zero emissions, low noise, and economical operation and maintenance, and are becoming more and more popular among users. The energy used by electric vehicles is the electricity provided by the power battery pack on board. Electric vehicles need to be charged after the electricity is used up. Due to the limitations of existing battery technology and charging technology, it takes a long time to fully charge an electric vehicle, which is not as simple and fast as refueling a fuel vehicle directly. Therefore, in order to reduce the waiting time of users, replacing the battery when the electric vehicle is running out of power is an effective means. In order to facilitate the replacement of batteries for electric vehicles and meet the battery replacement needs of electric vehicles, it is necessary to build battery replacement stations. With the rapid popularization of electric vehicles, more battery replacement stations need to be built to meet the demand.

[0003] In existing battery swap stations, in order to realize the removal or installation of the battery installed at the bottom of the electric vehicle, it is generally necessary to set up a lift to lift the electric vehicle to a certain height, and reserve enough space for the battery swap cart to enter and exit the bottom of the vehicle and perform the removal and installation operations. The lift is provided with a wheel limiting mechanism, which is installed in the opening of the driving platform. The wheel limiting mechanism is used to carry the wheels of the electric vehicle, and the front and rear adjustment of the position of the electric vehicle is achieved by the front and rear movement of the wheel limiting mechanism in the opening along the travel direction of the electric vehicle. However, due to the front and rear displacement of the wheel limiting mechanism along the travel direction, a gap will be formed between the outer edge of the wheel limiting mechanism and the inner wall of the opening, causing a safety hazard.

[0073] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0074] like Figure 1-Figure 8 As shown, this embodiment discloses a lift 1, which includes a driving platform 10. The driving platform 10 has an opening 11. A downwardly recessed wheel limiting mechanism 20 is installed in the opening 11. The wheel limiting mechanism 20 can be displaced forward and backward along the traveling direction of the battery swap vehicle to position battery swap vehicles of different specifications.

[0075] The lift 1 also includes a telescopic structure 30, which is located below the driving platform 10 and can be telescoped along the displacement direction of the wheel limiting mechanism 20. The telescopic structure 30 is used to close the gap between the opening 11 formed due to the front and rear displacement of the wheel limiting mechanism 20 along the traveling direction of the battery-swap vehicle.

[0076] In this way, by setting the telescopic structure 30, the gap formed between the outer edge of the wheel limiting mechanism 20 and the inner wall of the opening 11 is closed to avoid safety hazards, such as damage to internal components caused by the entry of garbage and debris, and personal injury to personnel, thereby improving the safety of the lift 1.

[0077] It should be noted that, since the telescopic structure 30 can be telescoped along the displacement direction of the wheel limiting mechanism 20, and the wheel limiting mechanism 20 can be displaced forward and backward along the traveling direction of the battery-swap vehicle; therefore, the telescopic direction P of the telescopic structure 30 is in the same direction as the displacement direction of the wheel limiting mechanism 20; and the telescopic direction P of the telescopic structure 30 is in the same direction as the width direction of the telescopic structure 30, that is, the telescopic direction P of the telescopic structure 30 is perpendicular to the length direction L of the telescopic structure 30. The width direction of the telescopic structure 30 is in the same direction as the width direction of the lift 1.

[0078] In addition, Figure 2 and Figure 3 The driving platform 10 of the lift 1 is removed in order to better demonstrate the positional relationship between the telescopic structure 30 and the wheel limiting mechanism 20 .

[0079] In this embodiment, the telescopic structure 30 includes a first telescopic part 31 and a second telescopic part 32 which are stacked along the height direction H of the lift 1 and movably connected to each other. The first telescopic part 31 is slidably arranged on the lower surface of the driving platform 10 and is clamped between the driving platform 10 and the second telescopic part 32 along the height direction H. The second telescopic part 32 is fixedly connected to the wheel limiting mechanism 20.

[0080] The movement of the second telescopic portion 32 in a direction away from the first telescopic portion 31 drives the first telescopic portion 31 to move from the initial position to a closed position of the closed gap, and the first telescopic portion 31 can be restored to the initial position under the action of the restoring force; along the telescopic direction P of the telescopic structure 30, the first telescopic portion 31 and the second telescopic portion 32 are always guaranteed to overlap at least partially along the height direction H.

[0081] In this way, through the above-mentioned arrangement, a specific structural form of a telescopic structure 30 is provided, in which the first telescopic part 31 and the second telescopic part 32 cooperate with each other to always maintain the gap formed by the front-rear displacement between the outer edge of the closed wheel limiting mechanism 20 and the inner wall of the opening 11 along the traveling direction of the battery-exchange vehicle, and the structure is simple and compact.

[0082] The lower surface of the first telescopic part 31 is provided with a fixing part 311, and the fixing part 311 extends downward along the height direction H; the second telescopic part 32 is provided with a connecting part 321 at a position corresponding to the fixing part 311 of the first telescopic part 31, and the connecting part 321 can abut against the fixing part 311. In this way, the movable connection between the fixing part 311 of the first telescopic part 31 and the connecting part 321 of the second telescopic part 32 is realized by the matching mode of the fixing part 311 of the first telescopic part 31 and the connecting part 321 of the second telescopic part 32, that is, when the second telescopic part 32 moves away from the first telescopic part 31, the connecting part 321 can abut against the fixing part 311 to drive the first telescopic part 31 to leave the initial position; when the second telescopic part 32 moves closer to the first telescopic part 31, the connecting part 321 is separated from the fixing part 311, and the first telescopic part 31 returns to the initial position under the action of the restoring force.

[0083] Specifically, the first telescopic part 31 includes a first main body 312 and an extension part 313, the extension part 313 is arranged at the outer edge of the first main body 312 on the side close to the second telescopic part 32 along the length direction L of the telescopic structure 30, and the extension part 313 extends in the telescopic direction P toward the second telescopic part 32, and the fixing part 311 is arranged on the lower surface of the extension part 313. The second telescopic part 32 includes a second main body 322 and a connecting part 321, the connecting part 321 is connected to the outer edge of the second main body 322 along the length direction L of the telescopic structure 30, and extends in the direction away from the second main body 322 along the length direction L of the telescopic structure 30, and the projection of the connecting part 321 and the fixing part 311 along the telescopic direction P at least partially overlap. In this way, by setting the specific structure of the first telescopic part 31 and the second telescopic part 32, the matching dimensions of the two along the length direction L of the telescopic structure 30 are made compact.

[0084] The dimension of the first body 312 of the first telescopic part 31 along the length direction L of the telescopic structure 30 is greater than the dimension of the second body 322 of the second telescopic part 32 along the length direction L of the telescopic structure 30, and the dimension of the second body 322 of the second telescopic part 32 along the length direction L of the telescopic structure 30 is greater than or equal to the dimension of the opening 11 along the length direction L of the telescopic structure 30. In this way, by setting the dimension of the first body 312 of the first telescopic part 31 along the length direction L of the telescopic structure 30 to be greater than the dimension of the second body 322 of the second telescopic part 32 along the length direction L of the telescopic structure 30, and the dimension of the second body 322 of the second telescopic part 32 along the length direction L of the telescopic structure 30 is greater than or equal to the dimension of the opening 11 along the length direction L of the telescopic structure 30, that is, the dimensions of the first telescopic part 31 and the second telescopic part 32 along the length direction L of the telescopic structure 30 can cover the dimension of the opening 11 along the length direction L of the telescopic structure 30, thereby realizing the closure of the opening 11 along the length direction L of the telescopic structure 30 by the portion provided with the first telescopic part 31 and the second telescopic part 32.

[0085] Preferably, the number of the fixing parts 311 and the number of the extending parts 313 are both two; the two extending parts 313 are respectively arranged near the opposite outer edges of the first body 312 along the perpendicular direction of the telescopic direction P, that is, the two extending parts 313 are respectively arranged near the opposite outer edges of the first body 312 along the length direction L of the telescopic structure 30; the two fixing parts 311 are respectively arranged on the lower surfaces of the two extending parts 313. In this way, through the above arrangement, the movement of the second telescopic part 32 can drive the movement of the first telescopic part 31 to be more stable.

[0086] In this embodiment, the telescopic structure 30 further includes an elastic reset member 33, the number of which is two, and the two elastic reset members 33 are respectively connected between the two fixed parts 311 and the driving platform 10; wherein the two elastic reset members 33 always exert a force on the first telescopic part 31 to make the first telescopic part 31 return to the initial position. In this way, by setting an elastic member to exert a force on the first telescopic part 31 to make the first telescopic part 31 return to the initial position, the first telescopic part 31 can return to the initial position after being separated from the force exerted on it by the second telescopic part 32, so as to always maintain a closed gap; by setting the elastic reset member 33 connected to the fixed part 311 of the first telescopic part 31, the overall structure is made more compact; by setting the number of the elastic reset members 33 to be two, and the two elastic reset members 33 are respectively connected between the two fixed parts 311 and the driving platform 10, the restoring force exerted by the elastic reset member 33 on the first telescopic part 31 can be distributed more evenly, so that the movement of the first telescopic part 31 in returning to the initial position is more stable. Specifically, the elastic reset member 33 is a spring.

[0087] Furthermore, a first bracket 34 extending along the length direction L of the telescopic structure 30 is provided on the fixing portion 311, a second bracket 35 is convexly provided on the lower surface of the driving platform 10, and the second bracket 35 extends downward along the height direction H, and the two ends of the elastic reset member 33 are respectively connected to the first bracket 34 and the second bracket 35. In this way, by setting the first bracket 34 and the second bracket 35 to fix the elastic reset member 33, and by setting the specific positions of the first bracket 34 and the second bracket 35, the overall structure of the telescopic structure 30 is made more compact and the overall occupied space is reduced. After the two ends of the elastic reset member 33 are respectively connected to the first bracket 34 and the second bracket 35, the setting direction of the elastic reset member 33 is in the same direction as the telescopic direction P of the telescopic structure 30, so that the elastic restoring force applied by the elastic reset member 33 to the first telescopic portion 31 can be most efficient.

[0088] In this embodiment, a boss 41 is provided on the lower surface of the driving platform 10, and the boss 41 is provided on both sides of the first telescopic part 31, and each boss 41 is provided with an inwardly recessed slide groove 411 on one side close to the first telescopic part 31, and the first telescopic part 31 is respectively slidably disposed in the two slide grooves 411 on the opposite sides along the length direction L of the telescopic structure 30. In this way, by providing the slide grooves 411, a specific arrangement mode of the first telescopic part 31 being slidably disposed on the lower surface of the driving platform 10 is provided, and by arranging the first telescopic part 31 to be respectively slidably disposed in the slide grooves 411 on the two sides corresponding to the telescopic direction P perpendicular to the telescopic direction, the sliding of the first telescopic part 31 is made smoother. Furthermore, by providing the slide grooves 411 in a recessed form on the bosses 41 on both sides of the first telescopic part 31 on the lower surface of the driving platform 10, the overall structure is made more compact.

[0089] Specifically, the slide groove 411 is an L-shaped slide groove 411, so as to effectively save the dimension of the length direction L of the telescopic structure 30 through a compact structure.

[0090] The lift 1 further includes a stopper 42, which is disposed at the edge of the lower surface of the driving platform 10, and is used to limit the first telescopic portion 31 to be located at the initial position. In this way, by disposing the stopper 42 located at the edge of the lower surface of the driving platform 10, the first telescopic portion 31 is limited to prevent the first telescopic portion 31 from being reversely disengaged from the initial position under the action of the restoring force. There are multiple stoppers 42, and the multiple stoppers 42 are arranged at equal intervals along the length direction L of the telescopic structure 30 to provide more blocking points, thereby improving the limiting effect on the first telescopic portion 31.

[0091] Preferably, there are two telescopic structures 30, which are respectively arranged at the front and rear ends of the wheel limiting mechanism 20 along the telescopic direction P. In this way, by respectively arranging two telescopic structures 30 at the front and rear ends of the wheel limiting mechanism 20 along the telescopic direction P, the gap between the outer edge of the front end of the wheel limiting mechanism 20 and the inner wall of the opening 11 and the gap between the outer edge of the rear end of the wheel limiting mechanism 20 and the inner wall of the opening 11 are closed, thereby better improving the safety of the lift 1.

[0092] Preferably, the lift 1 further includes a driving mechanism 50, which is used to drive the wheel limiting mechanism 20 to move forward and backward along the traveling direction of the battery-swap vehicle;

[0093] The lift 1 also includes a support frame 60 disposed below the wheel limiting mechanism 20, on which a slide rail 71 and a slider 72 slidably matched with the slide rail 71 are disposed, and the wheel limiting mechanism 20 is fixed on the slider 72. In this way, by setting the driving mechanism 50, the wheel limiting mechanism 20 can be moved forward and backward along the direction of travel of the battery swapping vehicle, thereby enabling the mobile base to move forward and backward along the direction of travel of the battery swapping vehicle, thereby adapting to battery swapping vehicles with different wheelbases to adjust to the accurate battery swapping position. By setting the slide rail 71 and the slider 72, the wheel limiting mechanism 20 can be moved forward and backward along the direction of travel of the battery swapping vehicle.

[0094] Specifically, the wheel limiting mechanism 20 includes a mounting seat 21 , the top surface of which is V-shaped and has two rows of rollers 22 to form a depression. The mounting seat 21 of the wheel limiting mechanism 20 is fixed on the slider 72 .

[0095] The present embodiment further provides a battery swap station, which includes the above lift 1. The present embodiment provides a telescopic structure 30 in the lift 1 of the battery swap station to seal the gap formed between the outer edge of the wheel limiting mechanism 20 and the inner wall of the opening 11, thereby avoiding potential safety hazards, such as damage to internal components caused by the entry of garbage and debris, and personal injury to personnel, etc., thereby improving the safety of the lift 1 and the battery swap platform.
