Description

[0001] This application is a divisional application of a Chinese patent application with an application date of January 23, 2020, application number 2020100769404, and invention name “Bidirectional mobile platform and shuttle vehicle including the same”. Technical Field

[0002] The invention relates to a bidirectional mobile platform.

[0003] The invention also relates to a shuttle vehicle comprising the bidirectional moving platform. Background Art

[0004] Quick-swap electric vehicles can meet the power supply needs of electric vehicles by replacing battery packs. In the process of replacing battery packs, a shuttle is needed. The shuttle is used to transport the battery pack between the electric vehicle and the battery compartment. It also has the function of unlocking the old battery pack from the electric vehicle and inserting and locking the new battery pack into the electric vehicle. Unlocking the battery pack from the electric vehicle and locking the battery pack in the electric vehicle is a relatively complex process, which requires the horizontal movement of the battery pack and the unlocking device to be controlled separately.

[0005] From the above description, it can be seen that the installation and removal process of the battery pack requires adjustment of the position between the battery pack and related components and the fixing seat, and the position of the battery pack needs to be adjusted separately during the installation and removal process. However, since the fixing seat of the electric vehicle is set at the bottom of the electric vehicle, the overall height of the shuttle vehicle used for battery replacement cannot be designed to be too thick. Therefore, it is necessary to design a two-way mobile platform that can control the overall movement of the battery pack and related components, and can also control the horizontal movement of the battery pack separately.

[0088] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0089] Embodiment 1

[0090] like Figures 1 to 3As shown, the present invention provides a bidirectional movable platform 100, including a lower frame 1, an upper frame 2, a first driving unit 3, a first connecting member 4, a second driving unit 5 and a second connecting member 6, the upper frame 2 is located above the lower frame 1; the first driving unit 3 is connected to the upper frame 2 through the first connecting member 4, and the first driving unit 3 drives the upper frame 2 to move; the second driving unit 5 is connected to the lower frame 1 through the second connecting member 6, and the second driving unit 5 drives the lower frame 1 to move.

[0091] The battery pack is placed on the upper frame 2, and the unlocking device 60 and other components are arranged on the lower frame 1. Since the upper frame 2 and the lower frame 1 are driven by the first driving part 3 and the second driving part 5 respectively, the upper frame 2 and the lower frame 1 can move together or separately.

[0092] The first driving unit 3, the second driving unit 5, and the second connecting member 6 are located below the lower frame 1, and the lower frame 1 forms an avoidance area 11 for avoiding the first connecting member 4, and the first connecting member 4 is located in the avoidance area 11. The lower frame 1 forms the avoidance area 11 for avoiding the first connecting member 4, so that the overall height of the two-way mobile platform 100 can be controlled within a certain range, so that the two-way mobile platform 100 can be moved to the bottom of the electric vehicle.

[0093] The bidirectional movable platform 100 further includes a guide rail 7, a first slider 8 and a second slider 9. The guide rail 7 is located below the lower frame 1. The first slider 8 is fixed to the upper frame 2 and slides on the guide rail 7. The second slider 9 is fixed to the lower frame 1 and slides on the guide rail 7. The lower frame 1 forms a through area 12 for accommodating the first slider 8, and the first slider 8 is located in the through area 12. The first slider 8 and the second slider 9 share the same guide rail 7, making the overall structure of the bidirectional movable platform 100 more compact.

[0094] like Figures 2 to 3 As shown, the first driving part 3 includes a first driving member 31 and a first screw rod 32. The first driving member 31 drives the first screw rod 32 to rotate. The axis of the first screw rod 32 is parallel to the extension direction of the guide rail 7. The first connecting member 4 is a first screw rod nut 41. The first screw rod nut 41 is sleeved on the first screw rod 32. The first screw rod nut 41 is threadedly connected with the first screw rod 32, and the first screw rod nut 41 is fixed to the upper frame 2. The first driving member 31 drives the first screw rod 32 to rotate, so that the first screw rod nut 41 moves on the first screw rod 32, so that the upper frame 2 fixed to the first screw rod nut 41 can move along the direction of the guide rail 7.

[0095] like Figures 2 to 3As shown, the second driving part 5 includes a second driving member 51 and a second screw rod 52. The second driving member 51 drives the second screw rod 52 to rotate. The axis of the second screw rod 52 is parallel to the extension direction of the guide rail 7. The second connecting member 6 is a second screw nut 61. The second screw nut 61 is sleeved on the second screw rod 52. The second screw nut 61 is threadedly connected with the second screw rod 52, and the second screw nut 61 is fixed to the lower frame 1. The second driving member 51 drives the second screw rod 52 to rotate, so that the second screw nut 61 moves on the second screw rod 52, so that the lower frame 1 fixed with the second screw nut 61 can move along the direction of the guide rail 7.

[0096] In this embodiment, there are two guide rails 7, which are parallel to each other and are respectively located on both sides of the lower frame 1. The number of guide rails 7 is not limited to two, and may also be multiple guide rails parallel to each other.

[0097] In this embodiment, the number of the first driving parts 3 is two, the number of the first connecting members 4 (i.e., the first screw nut 41) is two, and the first driving parts 3 and the first connecting members 4 are arranged in a one-to-one correspondence. The number of the first driving parts 3 and the first connecting members 4 is not limited to two, and can also be set to multiple.

[0098] In this embodiment, the number of the second driving parts 5 is two, the number of the second connecting members 6 (i.e., the second screw nut 61) is two, and the second driving parts 5 and the second connecting members 6 are arranged one by one. The number of the second driving parts 5 and the second connecting members 6 is not limited to two, and can also be set to multiple.

[0099] like Figures 4 to 6 As shown, the bidirectional mobile platform 100 also includes a battery tray 10, which is connected to the top of the upper frame 2 and is used to place battery packs.

[0100] The surface of the upper frame 2 facing the battery tray 10 is provided with an insertion slot 21, and the extension direction of the insertion slot 21 forms an angle with the moving direction of the upper frame 2. The surface of the battery tray 10 facing the upper frame 2 is provided with an insert 101, and the insert 101 is located in the insertion slot 21. When the battery tray 10 is placed on the upper frame 2, since the extension direction of the insertion slot 21 forms an angle with the moving direction of the upper frame 2, the upper frame 2 can drive the battery tray 10 to move when it moves. The insert 101 is not fixedly connected to the insertion slot 21, and the battery tray 10 can be easily removed from the upper frame 2, which is convenient for replacing the battery tray 10. The angle between the extension direction of the insertion slot 21 and the moving direction of the upper frame 2 is preferably a right angle, that is, the extension direction of the insertion slot 21 is perpendicular to the moving direction of the upper frame 2.

[0101] The two-way mobile platform 100 further includes a plurality of first elastic members 20, which are disposed between the battery tray 10 and the upper frame 2, and the two ends of the first elastic member 20 are respectively connected to the battery tray 10 and the upper frame 2. When the battery tray 10 holds the battery pack, since the first elastic member 20 is disposed between the battery tray 10 and the upper frame 2, the battery tray 10 has a buffer distance and will not directly hit the upper frame 2, thereby preventing the battery pack and related components from being damaged due to excessive force.

[0102] The two-way mobile platform also includes an unlocking device 60, which is fixed to the lower frame 1 and is used to cooperate with the locking mechanism of the electric vehicle. The locking mechanism of the electric vehicle locks the battery pack; when the battery tray 10 holds the battery pack, the unlocking device 60 cooperates with the locking mechanism on the electric vehicle to unlock the locking mechanism, so that the battery pack can be taken out of the electric vehicle.

[0103] The bidirectional mobile platform further includes a first positioning fork 30, which is used to cooperate with the positioning block of the battery pack, and the first positioning fork 30 is fixed on the battery tray 10. The positioning block of the battery pack can be a positioning block specifically matched with the first positioning fork 30, or a structure that realizes other functions and also has the function of positioning after cooperating with the first positioning fork 30, such as locking the shaft.

[0105] like Figure 1 As shown, a visual sensor 80 is also provided on the lower frame 1, and the visual sensor 80 is used to detect whether the locking mechanism is in the locking position. For example, it can be determined whether the locking mechanism is in the locking position by detecting whether the lock link is in the locking position.

[0106] like Figure 1As shown, the bidirectional mobile platform also includes a first start sensor 91, which is arranged on the upper frame 2. The first start sensor 91 is used to detect whether there is a battery tray 10 above the upper frame 2. The first start sensor 91 is also used to generate a first start signal when the battery tray 10 is detected above the upper frame 2. The first start sensor 91 is also used to send the first start signal to the first drive unit 3 and the second drive unit 5. The first drive unit 3 and the second drive unit 5 are also used to act after receiving the first start signal. By setting the first start sensor 91, only when there is a battery tray 10 on the upper frame 2, the lower frame 1 and the upper frame 2 can perform corresponding actions under the control of the first drive unit 3 and the second drive unit 5.

[0107] like Figure 1 As shown, the bidirectional mobile platform also includes a second start sensor 92, which is arranged on the upper frame 2. The second start sensor 92 is used to detect whether there is a battery pack on the upper frame 2. The second start sensor 92 is also used to generate a second start signal when the battery pack is detected on the upper frame 2. The second start sensor 92 is also used to send the second start signal to the first drive unit 3 and the second drive unit 5. The first drive unit 3 and the second drive unit 5 are also used to act after receiving the second start signal. By setting the second start sensor 92, only when there is a battery pack on the upper frame 2, the lower frame 1 and the upper frame 2 can perform corresponding actions under the control of the first drive unit 3 and the second drive unit 5.

The lock link 700 can drive the lock tongue 602 to rotate. A lock shaft is provided in the circumference of the battery pack. When the battery pack is installed in the fixing seat, the lock shaft of the battery pack is fixed in the lock base 600; specifically, the lock shaft is inserted into the lock slot 601 from the entrance of the lock slot 601 until the locking position is reached, and the lock tongue 602 is lowered to lock the lock shaft in the lock slot 601. When the battery pack needs to be removed from the fixing seat, the lock shaft of the battery pack needs to be removed from the lock slot 601 of the lock base 600; specifically, the lock link 700 is actuated to drive the lock tongue 602 to rotate, so that the lock tongue 602 is retracted, and the lock shaft of the battery pack can be removed from the lock slot 601. The lock link 700 is provided with a force point 701. During the disassembly of the battery pack, the unlocking device presses against the force point 701 of the lock link 700 to retract the lock tongue 602.
