Description

Technical Field

[0001] This invention relates to the field of battery swapping technology for electric vehicles, and more specifically to a battery transport device and a battery swapping station for electric vehicles. Background Technology

[0002] Compared to gasoline-powered vehicles, electric vehicles (EVs) offer numerous advantages and have gradually gained acceptance and widespread adoption. However, the issue of battery range extension has consistently hindered their rapid development. One approach to achieve rapid battery range extension for EVs is fast charging. However, even with fast charging, the charging time for EVs remains significantly longer compared to the immediate refueling and driving experience of gasoline-powered vehicles. Another approach involves battery swapping at battery swapping stations. The battery range extension time is limited to the swapping time, resulting in a shorter waiting time compared to fast charging. During their ongoing research and development of battery swapping station products, the applicant's R&D team discovered that the battery transport device at the swapping station requires the vehicle to extend the battery a predetermined distance towards the station before the transport device can remove it. If the extension distance does not meet the set limit, the transport device struggles to remove the battery. Furthermore, the battery transport process is unstable, leading to potential damage from impacts and the risk of the battery falling off the transport device. Therefore, it is necessary to improve and optimize the battery transport devices of existing battery swapping stations. Summary of the Invention

They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] In this embodiment of the invention, a battery transport device and an electric vehicle battery swapping station are provided. Please refer to [reference needed]. Figures 1 to 14 As shown.

[0052] A battery transport device includes a battery transport compartment 1, a push-pull base 2, a push-pull drive mechanism, a locking hook base 3, a telescopic drive mechanism, a locking hook 4, and a locking drive mechanism.

[0053] Four transverse drive rollers 12 are rotatably connected to the bottom of the battery transport compartment 1, with the extension direction of the transverse drive rollers 12 along the front-rear direction of the battery transport compartment 1. A first support base 131 is provided on one side of the transverse drive rollers 12 at the bottom of the battery transport compartment 1. A row of longitudinal drive rollers 132 is rotatably connected to the first support base 131, with the extension direction of the longitudinal drive rollers 132 along the left-right direction of the battery transport compartment 1. A first lifting cylinder 14 is provided on the battery transport compartment 1, with its telescopic end connected to the first support base 131. When the telescopic end of the first lifting cylinder 14 extends relative to the cylinder body end, it drives the longitudinal drive rollers 132 higher than the transverse drive rollers 12; when the telescopic end of the first lifting cylinder 14 retracts relative to the cylinder body end, it drives the longitudinal drive rollers 132 lower than the transverse drive rollers 12.

[0054] When the battery 7 enters or exits the battery transport chamber 1 from the front inlet / outlet, the longitudinal drive roller 132 is made higher than the transverse drive roller 12, and the lower surface of the battery 7 rolls in contact with the longitudinal drive roller 132, so that the battery 7 enters or exits the battery transport chamber 1 smoothly.

[0055] The battery 7 enters and exits from the left or right entrance / exit of the battery transport compartment 1 to facilitate the transfer of the battery 7 between the battery transport compartment 1 and the battery storage compartment. At this time, the longitudinal drive roller 132 is lower than the transverse drive roller 12, and the battery 7 rolls into contact with the transverse drive roller 12, so that the battery 7 is transferred smoothly between the battery transport compartment 1 and the battery storage compartment.

[0056] Second support bases 151 are installed at the left and right entrances / exits of the battery transport compartment 1. A row of vertical drive rollers 152 are rotatably connected to the second support bases 151, and the vertical drive rollers 152 extend along the up-down direction of the battery transport compartment 1. A second lifting cylinder 16 is installed on the battery transport compartment 1, and the telescopic end of the second lifting cylinder 16 is connected to the second support base 151. When the telescopic end of the second lifting cylinder 16 extends relative to the cylinder body end, it drives the vertical drive rollers 152 to be higher than the horizontal drive rollers 12; when the telescopic end of the second lifting cylinder 16 retracts relative to the cylinder body end, it drives the vertical drive rollers 152 to be lower than the horizontal drive rollers 12.

[0057] When the battery 7 enters or exits the battery transport chamber 1 from the front inlet / outlet, the vertical drive roller 152 is made higher than the horizontal drive roller 12, and the left and right side surfaces of the battery 7 roll in contact with the vertical drive roller 152, so that the battery 7 enters or exits the battery transport chamber 1 smoothly.

[0058] When the battery 7 is transferred between the battery transport compartment 1 and the battery storage compartment, the vertical drive roller 152 on the side of the battery transport compartment 1 closest to the battery storage compartment is lower than the horizontal drive roller 12, so that the battery 7 can be transferred between the battery transport compartment 1 and the battery storage compartment.

[0059] The bottom and left and right sides of the front entrance of the battery transport compartment 1 are rotatably connected to guide rollers 17 to prevent the battery 7 from being damaged by collision with the entrance when it exits from the front entrance of the battery transport compartment 1.

[0060] A third lifting cylinder 18 is also provided at the bottom of the front entrance / exit of the battery transport compartment 1. A baffle 19 is provided at the telescopic end of the third lifting cylinder 18. The telescopic end of the third lifting cylinder 18 extends and retracts relative to the cylinder body end so that the baffle 19 blocks or disengages from the front entrance / exit of the battery transport compartment 1.

[0061] When battery 7 enters or exits from the front entrance / exit of battery transport chamber 1, the telescopic end of the third lifting cylinder 18 retracts relative to the cylinder body end, so that the baffle 19 disengages from the front entrance / exit of battery transport chamber 1; after battery 7 enters battery transport chamber 1, the telescopic end of the third lifting cylinder 18 extends relative to the cylinder body end, so that the baffle 19 blocks the front entrance / exit of battery transport chamber 1, preventing battery 7 from falling out of battery transport chamber 1.

[0062] The push-pull base 2 is slidably connected to the battery transport compartment 1, and the push-pull base 2 can move relative to the battery transport compartment 1 in the front and back directions.

[0063] Specifically, a slide rail 11 is provided on the left and right sides of the battery transport compartment 1. The slide rail 11 is arranged along the front and rear directions of the battery transport compartment 1. A slider 21 is provided on the push-pull base 2, and the slider 21 slides in conjunction with the slide rail 11.

[0064] The push-pull drive mechanism is used to drive the push-pull seat 2 to move relative to the battery transport compartment 1 in the front-to-back direction.

[0065] Specifically, the push-pull drive mechanism includes a drive pulley 51, a driven pulley 52, a transmission belt 53, and a first motor 54. A wheel seat is rotatably mounted at the rear end of the battery transport compartment 1, and the drive pulley 51 is rotatably connected to the wheel seat. A wheel seat is also mounted at the front end of the battery transport compartment 1, and the driven pulley 52 is rotatably connected to the wheel seat. The transmission belt 53 connects the drive pulley 51 and the driven pulley 52. ​​The first motor 54 is located at the rear end of the battery transport compartment 1, and its output shaft is connected to the drive pulley 51. A mounting base 22 is provided on the push-pull base 2, and the transmission belt 53 is mounted and connected to the mounting base 22.

[0066] The front end of the push-pull seat 2 is slidably connected to the locking hook seat 3, and the locking hook seat 3 can extend and retract relative to the push-pull seat 2 in the front and rear directions.

[0067] Specifically, the rear end of the push-pull seat 2 is provided with a first sliding sleeve 23, which is arranged along the front and rear directions of the push-pull seat 2. The rear end of the locking hook seat 3 is provided with a first sliding rod 31, which slides in conjunction with the first sliding sleeve 23.

[0068] The telescopic drive mechanism is used to drive the locking hook seat 3 to extend and retract relative to the push-pull seat 2 in the front and rear directions.

[0069] Specifically, the telescopic drive mechanism is set as an electric push rod 6, the cylinder end of the electric push rod 6 is connected to the push-pull seat 2, and the telescopic end of the electric push rod 6 is connected to the locking hook seat 3.

[0070] A locking hook component 4 is provided on the locking hook seat 3.

[0071] In this embodiment, a locking hook 4 is slidably connected to the locking hook seat 3, and the locking hook 4 can move relative to the locking hook seat 3 in the left and right directions.

[0072] Specifically, a second slide bar 32 is provided on the lock hook seat 3, and the second slide bar 32 is arranged along the left and right directions of the lock hook seat 3; a second sliding sleeve 41 is provided on the lock hook part 4, and the second sliding sleeve 41 slides in conjunction with the second slide bar 32.

[0073] The locking drive mechanism is used to drive the locking hook 4 to connect to or disconnect from the ring on the battery 7.

[0074] Specifically, the locking drive mechanism is used to drive the locking hook 4 to move relative to the locking hook seat 3 in the left and right directions. The locking hook 4 moves relative to the locking hook seat 3 in one direction to engage the locking hook 4 with the ring on the battery 7; the locking hook 4 moves relative to the locking hook seat 3 in the other direction to disengage the locking hook 4 from the ring on the battery 7.

[0075] The locking drive mechanism is a locking cylinder 8, with the cylinder body end of the locking cylinder 8 connected to the lock hook seat 3 and the telescopic end of the locking cylinder 8 connected to the lock hook part 4.

[0076] A flip motor 91 is provided on the side of the battery transport compartment 1, and the output shaft of the flip motor 91 is connected to a flip tentacle 92. The flip tentacle 92 is used to contact the flip baffle A on one side of the battery storage compartment; the output shaft of the flip motor 91 rotates to drive the flip tentacle 92 to rotate, and the flip tentacle 92 rotates to move the flip baffle A, so that the flip baffle A is higher or lower than the inlet and outlet edge of the battery storage compartment.

[0077] One end of the flip-up baffle A is hinged to one side of the battery storage compartment, and a return spring is connected between the flip-up baffle A and the battery storage compartment; a limit pin is provided on one side of the battery storage compartment, and a limit groove is opened on the flip-up baffle A, with the limit pin cooperating with the limit groove.

[0078] The flipping tentacle 92 rotates to actuate the flipping baffle A, causing it to be lower than the edge of the battery storage compartment's inlet / outlet, facilitating the entry and exit of the battery 7. After the battery 7 has entered or exited the battery storage compartment, the flipping tentacle 92 disengages from the flipping baffle A, and the flipping baffle A returns to its original position under the action of the return spring, making it higher than the edge of the battery storage compartment's inlet / outlet. Specifically, after the battery 7 enters the battery storage compartment, the flipping baffle A is higher than the edge of the battery storage compartment's inlet / outlet, thus blocking the battery 7 and preventing it from falling out of the battery storage compartment.

[0079] In addition, two proximity switches 93 are provided on the side of the battery handling compartment 1, and the output shaft of the flip motor 91 is also provided with a sensing element 911 that can approach the sensing end of the proximity switch 93. The control end of the flip motor 91 and the proximity switches 93 are both connected to the control unit of the battery swapping station via signal cables. The output shaft of the flip motor 91 drives the flipping tentacles 92 to rotate to a first angle, so as to drive the sensing element 911 to approach one proximity switch 93; the output shaft of the flip motor 91 drives the flipping tentacles 92 to rotate to a second angle, so as to drive the sensing element 911 to approach the other proximity switch 93. In this way, the rotation angle range of the output shaft of the flip motor 91 is limited so that the rotation angle range of the flipping tentacles 92 corresponds to the swing stroke of the flipping baffle A, so that the flipping baffle A is higher or lower than the edge of the battery storage compartment entrance and exit.

[0080] In this embodiment, the output shaft of the flip motor 91 is connected to the input end of the transmission 94, and the two ends of the output end of the transmission 94 are respectively connected to the flip tentacle 92 and the sensing element 911.

[0082] The present embodiment has now been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the battery transport device and electric vehicle battery swapping station of the present invention. The battery transport device of the present invention is applied to an electric vehicle battery swapping station. After the electric vehicle extends the battery 7 toward the battery swapping station, the push-pull drive mechanism drives the push-pull seat 2 to move forward relative to the battery transport compartment 1. At this time, the locking hook 4 is located near the front of the battery 7, and the battery transport device and the battery 7 of the electric vehicle are in a coarse positioning state. Then, according to the visual recognition unit, the current distance between the locking hook 4 and the battery 7 is identified, and the telescopic drive mechanism drives the locking hook seat 3 to extend forward relative to the push-pull seat 2 by a corresponding distance. At this time, the locking hook 4 is located on one side of the ring buckle on the battery 7. Then, the locking drive mechanism drives the locking hook 4 to connect to the ring buckle on the battery 7. Finally, the push-pull drive mechanism drives the push-pull seat 2 to move backward relative to the battery transport compartment 1, and the telescopic drive mechanism drives the locking hook seat 3 to retract backward relative to the push-pull seat 2 to transfer the battery 7 into the battery transport compartment 1. This means that the electric vehicle does not need to extend the battery 7 towards the battery swapping station by a very precise distance, and the battery swapping station can also remove the battery 7 from the electric vehicle for battery swapping, thus achieving the universality of the battery swapping station for various models of electric vehicles.
