Description

Technical Field

[0001] This utility model belongs to the field of battery swapping technology for new energy vehicles, and relates to a battery swapping platform assembly for a new energy vehicle battery swapping device. Background Technology

[0002] New energy vehicles offer advantages such as environmental friendliness, energy efficiency, low noise, and low maintenance costs, leading to their increasing share in car sales. However, due to relatively long charging times, a significant portion of the population still refuses to purchase new energy vehicles.

[0003] To address the aforementioned issues, some automakers have introduced battery swapping solutions to improve the range of new energy vehicles. For example, Chinese patent application (application number: 202020893867.5) discloses a battery swapping device for electric vehicles, comprising: a bracket; a lifting seat, vertically slidably mounted on the bracket; a sliding seat, slidably mounted on the lifting seat; a rotating seat, rotatably mounted on the sliding seat; two battery receiving seats, mounted at both ends of the rotating seat; a battery gripping mechanism, slidably mounted on the two battery receiving seats; and a battery placement rack. The system involves sliding one battery receiver towards the car, then using a battery gripping mechanism to approach and remove the battery from the car, dragging it onto the battery receiver, and finally resetting the battery receiver to remove the empty battery. The other battery receiver and gripping mechanism then use the same steps to remove a full battery from a battery rack on one side. Next, a rotating base rotates, swapping the positions of the empty and full batteries. The battery receiver with the full battery is then brought close to the car, and the battery gripping mechanism pushes the battery into the car to install it. Similarly, the empty battery at the other end of the rotating base is pushed into the battery rack for recharging. However, in this structure, during battery placement and removal, the battery receiver needs to extend outward relative to the rotating base, leaving most of the battery receiver outside and suspended in the air. When the battery is placed on the battery receiver, its weight causes instability, with the outer end of the battery receiver tilting downwards and the inner end tilting upwards. This affects the sliding fit between the battery receiver and the rotating base, making it difficult for the battery receiver to return to its original position. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a battery swapping platform assembly for new energy vehicles. The technical problem to be solved by this utility model is: how to make the battery receiver return to its original position more smoothly.

[0005] The purpose of this utility model can be achieved through the following technical solution: a battery swapping platform assembly for a new energy vehicle battery swapping device, comprising a frame one, characterized in that it further comprises: a frame two, wherein the frame two is slidably disposed on the frame one;

[0006] Drive mechanism one is used to drive frame two to reciprocate along the length of frame one.

[0007] Battery receiver base; there are two battery receiver bases, and the two battery receiver bases are respectively fixed at both ends of the frame body two;

[0008] A battery gripping mechanism is used to pick up and put down batteries. There are two battery gripping mechanisms, which are located on two battery receiving seats respectively.

[0009] Two drive mechanisms are located on two battery receiving seats respectively and are used to drive the battery gripping mechanism to reciprocate along the length of the frame.

[0010] The two battery receivers of this invention are fixedly connected to the frame to form a whole, allowing the two battery receivers to move synchronously. When one end of the battery receiver extends out of the frame to pick up or put in a battery, the other end of the battery receiver remains inside the frame, ensuring that the center of gravity of the frame is always within the frame. The frame can always provide perfect support for the frame, allowing the frame to remain horizontal and slide smoothly with the frame. The return of the frame is also smoother.

[0011] In the aforementioned battery swapping platform assembly for new energy vehicles, guide rails are provided on both sides of the second frame, and horizontally arranged mounting plates are provided on both sides of the first frame. A placement groove for accommodating the first frame is formed between the two mounting plates. A pulley system that slides along the length of each mounting plate is provided. The second frame and the first frame are connected by a sliding engagement between the guide rails and the pulley system on both sides, resulting in better stability and smoother sliding.

[0012] In the aforementioned battery swapping platform assembly for new energy vehicles, a rack is fixedly mounted on the frame one along its length. The drive mechanism one includes a drive motor one and a gear shaft. A gear one is mounted on the gear shaft. The drive motor one is connected to the gear shaft via a transmission mechanism. The teeth of the rack one face downwards, and the gear one is located below the rack one and meshes with it. This top-mounted rack design, with the gear engaging the rack, ensures that the weight of the frame two is borne by the guide rail one and the pulley system, preventing the rack from being compressed and causing excessive wear, thus guaranteeing the movement accuracy and service life of the frame two.

[0013] In the aforementioned battery swapping platform assembly for new energy vehicles, the battery gripping mechanism includes a base plate, a guide plate fixedly connected to the base plate, two locking tongues slidably disposed at both ends of the guide plate, and a drive mechanism for driving the two locking tongues to translate along the length of the guide plate. Locking latches are provided on both sides of the outer end of the battery. The battery gripping mechanism uses the locking tongues at both ends of the guide plate to engage with the locking latches to pick up and place the battery.

[0014] In the aforementioned battery swapping platform assembly for new energy vehicles, the base plate and guide plate are fixedly connected by two spaced-apart angle brackets. A strip-shaped connector is also provided between the base plate and guide plate. This connector includes a long, strip-shaped connecting section and mounting portions located at both ends of the connecting section and bent relative to it. The mounting portions at both ends of the strip-shaped connector are respectively attached to the upper surfaces of the base plate and guide plate and connected by screws. The base plate and guide plate are fixed to the strip-shaped connector via angle brackets, forming a triangular connection between the base plate, guide plate, angle brackets, and strip-shaped connector, ensuring the connection strength between the base plate and guide plate.

[0015] In the aforementioned battery swapping platform assembly for new energy vehicles, a roller assembly is provided at the bottom of the battery receiving seat. The roller assembly includes several rollers rotatably connected to the battery receiving seat, and the rollers are spaced apart along the length of the frame. The roller assembly facilitates the entry and exit of the battery into the battery receiving seat and reduces wear on the battery casing.

[0016] In the battery swapping platform assembly of the new energy vehicle battery swapping device described above, each battery receiving seat is provided with two roller sets, which are located on both sides of the battery receiving seat.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. This utility model connects two battery receivers into a whole through a frame 2, so that when the battery receiver on one side extends out of the frame 1 to pick up or put down the battery, the center of gravity of the frame is still inside the frame 1, ensuring that the frame 1 remains horizontal and ensuring the sliding fit between the frame 1 and the frame 2, making it easier to pick up and put down the battery.

[0019] 2. The base plate and guide plate of the battery gripping mechanism are fixed in a triangular shape by corner brackets and connecting sections to ensure the connection strength between the base plate and the guide plate, which can better bear the weight of the battery and make battery picking and placing more stable and reliable.

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] A battery swapping platform assembly for a new energy vehicle battery swapping device is an improvement on a battery swapping device for an electric vehicle disclosed in Chinese patent application (application number: 202020893867.5). It can be used in conjunction with the bracket, lifting seat, rotating seat and battery placement rack in that patent, and its working principle is basically the same.

[0028] like Figure 1 , Figure 2 As shown, the battery swapping platform assembly includes a frame 1, a frame 2, two battery receiving seats 4, and two battery gripping mechanisms 5. The frame 2 is slidably mounted on the frame 1, and a drive mechanism 1 is provided between the frame 1 and the frame 2 to drive the frame 2 to reciprocate along the length of the frame 1. The two battery receiving seats 4 are respectively fixed at both ends of the frame 2. Each battery receiving seat 4 is provided with a battery gripping mechanism 5 and a drive mechanism 2. The battery gripping mechanism 5 is used to pick up and put in batteries 6, and the drive mechanism 2 is used to drive the battery gripping mechanism 5 to reciprocate along the length of the frame 2.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4As shown, the frame 1 has mounting plates 11 arranged opposite and parallel to each other on both sides. A placement groove 1a for accommodating the frame 2 is formed between the two mounting plates 11. Pulley groups 12 are arranged along the length direction on the inner side of each mounting plate 11. Guide rails 21 that cooperate with the pulley groups 12 are arranged on both sides of the frame 2. A rack 13 is also arranged on the inner side of each mounting plate 11, with the tooth surface of the rack 13 facing downwards. The drive mechanism includes a drive motor 31 and a gear shaft 32. 31 is fixed on the second frame 2. The gear shaft 32 is rotatably mounted on the second frame 2 and is connected to the drive motor 31 via belt drive. Gears 33 are fixed at both ends of the gear shaft 32. The gears 33 are located below the two racks 13 and mesh with the racks 13, so that the drive motor 31 can drive the second frame 2 to translate along the length of the first frame 1. The weight of the second frame 2 is supported by the guide rail 21 and the pulley block 12 to prevent the racks from being pressured and worn too quickly.

[0030] like Figure 1 , Figure 2 , Figure 3As shown, the battery receiving base 4 is located at both ends of the frame 2. The bottom of the battery receiving base 4 is provided with guide rail 41 and rack 42 along the length direction. The guide rail 41 consists of two spaced-apart rails located on both sides of the rack 42. The battery gripping mechanism 5 slides with the two guide rails 41. The drive mechanism 2 also adopts a gear and rack transmission mechanism to cooperate with the rack 42. The drive motor 2 7 drives the battery gripping mechanism 5 to move along the guide rail 41. The battery gripping mechanism 5 includes a base plate 51, a guide plate 52, two locking tongues 53, and a drive mechanism 3. The base plate 51 is fixedly connected to the guide plate 52. Both ends of the guide plate 52 are provided with locking tongues 53 that can move along the length direction of the guide plate 52. The drive mechanism 3 includes a drive motor 3 54, a swing block 55, and two connecting rods 56. The swing block 55 is elongated. The middle part of the swing block 55 is fixedly connected to the output shaft of the drive motor 3 54, and both ends are connected to one end of a connecting rod 56. The other end of each connecting rod 56 is connected to the locking tongue 53, so that the drive motor 3 54 can drive the locking tongue 53 to move back and forth along the length direction of the guide plate 52. The battery 6 has latches on both sides of its outer end. The battery gripping mechanism 5 can pick up and put down the battery 6 by cooperating with the latches on the battery 6 through the locking tongues 53. Furthermore, two sets of roller shafts 43 are arranged along the length of the bottom outward end of the battery receiving seat 4. Each set of roller shafts 43 includes several rollers, which are rotatably connected to the battery receiving seat 4 and spaced apart along the length of the frame 2. The two sets of roller shafts 43 are located on both sides of the battery receiving seat 4. When the battery gripping mechanism 5 picks up and puts in the battery 6, the roller shafts 43 can contact the battery 6 and provide support, facilitating the entry and exit of the battery 6 from the battery receiving seat 4. Furthermore, rollers 44 are also provided on both sides of the battery receiving seat 4 along the length of the frame 2. The rollers 44 can guide the battery 6 when it enters and exits the battery receiving seat 4 and prevent wear on the surface of the battery 6.

[0031] like Figure 3 , Figure 5 As shown, the base plate 51 and the guide plate 52 are fixedly connected by two spaced corner brackets 57. Two strip-shaped connectors 58 are also provided between the base plate 51 and the guide plate 52. Each strip-shaped connector 58 includes a long connecting section 581 and mounting portions 582 located at both ends of the connecting section 581 and bent relative to it. The mounting portions 582 at both ends of the strip-shaped connector 58 are respectively attached to the upper surfaces of the base plate 51 and the guide plate 52 and connected by screws, forming a triangular fixation between the base plate 51, the guide plate 52, the corner brackets 57, and the strip-shaped connectors 58. When the battery gripping mechanism 5 fixes the battery 6, the strip-shaped connectors 58 can exert a pulling force on the guide plate 52, preventing excessive stress on the corner brackets 57 due to the excessive weight of the battery 6, and ensuring the connection stability between the guide plate 52 and the base plate 51.

[0032] When the present invention retrieves or places the battery 6, the two battery receiving seats 4 move synchronously with the frame 2, so that one of the battery receiving seats 4 extends out of the frame 1, while the other battery receiving seat 4 is located inside the frame 1. This ensures that the center of gravity of the two battery receiving seats 4 and the frame 2 as a whole is still located inside the frame 1 and is supported by the guide rail 21 and the pulley group 12, so that the frame 2 can still maintain a horizontal state and ensure the matching accuracy of the guide rail 21 and the pulley group 12.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0034] Although this document frequently uses terms such as frame 1, mounting plate 11, placement slot 1a, pulley block 12, rack 13, frame 2, guide rail 21, drive motor 31, gear shaft 32, and gear 33, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
