Description

Technical Field

[0001] The present invention relates to the technical field of battery loading and unloading of new energy vehicles, and in particular to a battery replacement device and a battery replacement system. Background Art

[0002] With the increasing depletion of oil resources and a growing emphasis on environmental protection, new energy vehicles (NEVs) have seen significant development. Powered by batteries, NEVs do not burn fuel or emit toxic exhaust, offering energy-saving and environmentally friendly advantages. Batteries, as an essential component, provide the power source for NEVs.

Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0044] See also Figures 1 to 5 , a battery swap device 100 provided in one embodiment of the present invention is configured to travel on a predetermined track 110. The track 110 may be an I-shaped steel rail, laid in a straight line and / or curve as needed to facilitate the transport of battery packs. In this embodiment, the battery swap device 100 includes a base 120, a travel mechanism 130, a lifting mechanism 140, a rotating mechanism 150, a horizontal adjustment mechanism 160, and an unlocking mechanism 170.

[0045] See also Figure 1, wherein the base 120 serves as a foundation for carrying the lifting mechanism 140, the rotating mechanism 150, the horizontal adjustment mechanism 160 and the unlocking mechanism 170. The base 120 is provided with a traveling mechanism 130, which is used to drive the base 120 to move along the track 110, thereby driving the lifting mechanism 140, the rotating mechanism 150, the horizontal adjustment mechanism 160 and the unlocking mechanism 170 to move along the track 110; the unlocking mechanism 170 can be provided on the rotating mechanism 150 or the lifting mechanism 140, and is used to release the locked state of the battery pack on the chassis of the vehicle, thereby realizing the unlocking of the battery pack; the lifting mechanism 140 is provided on the base 120, and the lifting mechanism 140 is provided on the base 120. The mechanism 140 is provided with a rotating mechanism 150 and a horizontal adjustment mechanism 160. The lifting mechanism 140 is used to drive the rotating mechanism 150 and the horizontal adjustment mechanism 160 to rise and fall. Since the rotating mechanism 150 has a support 151 for carrying the battery pack, after the unlocking mechanism 170 unlocks the battery pack, the battery pack is located on the support 151, so that the rotating mechanism 150 can drive the battery pack to rotate. Since the rotating mechanism 150 and the horizontal adjustment mechanism 160 are connected, the horizontal adjustment mechanism 160 drives the rotating mechanism 150 to move, and then can drive the battery pack to move. The rotating mechanism 150 and the horizontal adjustment mechanism 160 have a reasonable and compact layout space.

[0046] The battery replacement device 100 mentioned above unlocks the battery pack on the chassis of the car through the unlocking mechanism 170. After being unlocked, the low-charged battery pack is located on the support 151 of the rotating mechanism 150, and the base 120 is driven by the traveling mechanism 130 to move on the track 110 to transport the unlocked low-charged battery pack out, and then the base 120 is driven by the traveling mechanism 130 to transport the fully charged battery pack back to the location of the car for replacement. Since the horizontal adjustment mechanism 160 is connected to the rotating mechanism 150, the fully charged battery pack is rotated and positioned when the rotating mechanism 150 drives the fully charged battery pack to rotate and position. At the same time, the horizontal adjustment mechanism 160 can be used to drive the battery to adjust its position in the horizontal direction, thereby completing the positioning of the battery. After the horizontal adjustment mechanism 160, the rotating mechanism 150 and the fully charged battery are lifted by the lifting mechanism 140, the fully charged battery pack pushes open the unlocking slider at the bottom of the car to complete the installation of the fully charged battery pack. The total height of the horizontal adjustment mechanism 160, the rotating mechanism 150 and the battery pack is set within a preset height range, which adapts to the height of the car chassis, so that the battery replacement equipment 100 has a reasonable layout space and occupies less space.

[0047] See also Figure 2The travel mechanism 130 includes a second driving member 131, a second transmission assembly 132, a roller 133 and a rotating shaft 134. The second transmission assembly 132 is connected between the second driving member 131 and the rotating shaft 134. The rotating shaft 134 is connected to the base 120. The roller 133 is sleeved on the rotating shaft 134 and rolls relative to the predetermined track 110 under the drive of the second driving member 131 to drive the base 120 to move relative to the predetermined track 110, thereby realizing the transportation of the battery pack.

[0048] The second transmission assembly 132 includes a first pulley 1321, a first synchronous belt 1322, and a second pulley 1323. The first pulley 1321 is disposed on the output shaft of the second driving member 131, the first synchronous belt 1322 is connected between the first pulley 1321 and the second pulley 1323, and the second pulley 1323 is mounted on the rotating shaft 134. Thus, the power of the second driving member 131 is transmitted to the rotating shaft 134 via the first pulley 1321, the first synchronous belt 1322, and the second pulley 1323, thereby driving the roller 133 mounted on the rotating shaft 134 to rotate, thereby driving the base 120 to move on the track 110.

[0049] In addition, in order to ensure the tracking stability of the roller 133 when walking on the track 110 and avoid derailment, a guide member 121 is provided on the base 120, and the guide member 121 is used to limit the rolling of the roller 133 on the track 110.

[0050] Specifically, the guide members 121 in this embodiment are guide wheels. In one embodiment of the present invention, two parallel rails 110 are spaced apart. Therefore, two pairs of guide wheels are provided in this embodiment, each pair being located on the inner side of a rail 110 . When the travel mechanism 130 is driven, the guide wheels can rotate accordingly.

[0051] See also Figure 1 and Figure 3 The lifting mechanism 140 includes a mounting seat 141 and a lifting seat 142. The rotating mechanism 150 and the horizontal adjustment mechanism 160 are arranged on the mounting seat 141. Thus, the lifting seat 142 drives the mounting seat 141 to drive the rotating mechanism 150 and the horizontal adjustment mechanism 160 to rise and fall.

[0052] Specifically, the lifting seat 142 includes a longitudinal member 1421, a lifting member 1422, a third driving member 1423, a third transmission assembly 1424 and a rotating member 1425. The longitudinal member 1421 is arranged on the base 120, the third driving member 1423, the third transmission assembly 1424 and the rotating member 1425 are arranged on the longitudinal member 1421, the third transmission assembly 1424 is transmission-connected between the third driving member 1423 and the rotating member 1425, one end of the lifting member 1422 is rotationally connected relative to the rotating member 1425, and the other end is connected to the mounting seat 141 to drive the mounting seat 141 to rise and fall.

[0053] Among them, the third transmission component 1424 includes a third pulley 14241, a second synchronous belt 14242 and a fourth pulley 14243, wherein the third pulley 14241 is arranged on the output shaft of the third driving member 1423, the third driving member 1423 is a motor, the second synchronous belt 14242 is connected between the third pulley 14241 and the fourth pulley 14243, and the fourth pulley 14243 is sleeved on the rotating member 1425, so that the third transmission component 1424 transmits power to the rotating member 1425, drives the rotating member 1425 to rotate, and then the rotation of the rotating member 1425 drives the lifting member 1422 to make a linear motion, so that the lifting member 1422 drives the mounting seat 141 to rise and fall. In a preferred embodiment, a screw mechanism is used to convert the rotational motion of the third transmission assembly 1424 into the linear motion of the lifting member 1422, that is, a vertically arranged screw is provided on the longitudinal member 1421, and a matching nut on the screw is fixed on the lifting member 1422. At the same time, in order to maintain the stability of the movement process of the lifting member 1422, at least one guide rail is also provided on the longitudinal member 1421. The component composition and installation method of the guide rail are already known to technicians in this field and will not be repeated here.

[0054] In one embodiment of the present invention, the lifting mechanism 140 includes two lifting seats 142 , which are disposed at opposite ends of the mounting seat 141 , thereby driving the mounting seat 141 to move up and down through the two lifting seats 142 to ensure smooth lifting.

[0055] See also Figure 4 In one embodiment of the present invention, the rotating mechanism 150 includes a fourth driving member 152, a fourth transmission assembly 153, a rotating wheel 154 and a support member 151. The fourth transmission assembly 153 is transmission-connected between the fourth driving member 152 and the rotating wheel 154. The rotating wheel 154 is connected to the support member 151, and the battery pack is placed on the support member 151.

[0056] Among them, the fourth transmission assembly 153 includes a fifth pulley 1531, a third synchronous belt 1532, a sixth pulley 1533 and a gear 1534. The fifth pulley 1531 is sleeved on the output shaft of the fourth driving member 152. The fourth driving member 152 is a motor. The third synchronous belt 1532 is connected between the fifth pulley 1531 and the sixth pulley 1533. The gear 1534 and the sixth pulley 1533 are coaxially arranged. The gear 1534 is meshed with the rotating wheel 154, wherein the diameter of the gear 1534 is larger than the diameter of the sixth pulley 1533, so that the rotating wheel 154 is driven to rotate slowly by the gear 1534, so that the rotating wheel 154 drives the battery pack on the support member 151 to rotate smoothly.

[0057] Among them, see Figure 5 Since the battery pack has a hard surface, when it is placed on the support 151, in order to prevent the support 151 from wearing the battery pack, a buffer member 1511 is also provided on the support 151 to avoid damage to the battery pack.

[0058] Specifically, the buffer member 1511 in this embodiment is a rubber pad. In other embodiments, a flexible material such as a sponge pad may also be provided.

[0059] Please continue reading Figure 4 In one embodiment of the present invention, the horizontal adjustment mechanism 160 includes a first driving member 161, a first transmission assembly 162 and an adapter assembly 163. The first driving member 161 can be a motor. The first transmission assembly 162 is transmission-connected between the first driving member 161 and the adapter assembly 163. The adapter assembly 163 includes a fixing member 1631 and a connecting member 1632. The fixing member 1631 is connected to the first transmission assembly 162, the connecting member 1632 is connected to the fixing member 1631, and the rotating wheel 154 is rotatably connected relative to the connecting member 1632, so that the first driving member 161 drives the fixing member 1631 to move in the horizontal direction. Since the connecting member 1632 is connected to the fixing member 1631, the rotating wheel 154 is rotatably connected relative to the connecting member 1632, so that the support member 151 can be driven to move in the horizontal direction through the first driving member 161.

[0060] Among them, the first transmission assembly 162 includes a coupling 1621, a screw rod 1622 and a connecting plate 1623. The connecting plate 1623 is rotatably connected relative to the screw rod 1622, so that the connecting plate 1623 moves horizontally relative to the screw rod 1622. The connecting plate 1623 is connected to the fixing member 1631, so that the movement of the connecting plate 1623 drives the movement of the fixing member 1631.

[0061] In one embodiment of the present invention, the support member 151 is annular, the connecting member 1632 and the fixing member 1631 are also annular, the rotating wheel 154 is located between the fixing member 1631 and the support member 151, and the rotating wheel 154 is rotatably connected relative to the connecting member 1632.

[0062] In addition, the first driving member 161 and the first transmission assembly 162 are both located in the annular support member 151, so that the horizontal adjustment mechanism 160 and the rotating mechanism 150 occupy less space and the spatial layout is compact, and the battery pack is located on the support member 151 of the rotating mechanism 150 and at the same time covers the horizontal adjustment mechanism 160, ensuring that the horizontal adjustment mechanism 160, the rotating mechanism 150 and the battery pack occupy less space, saving the supplier's land costs.

[0063] Among them, in order to make the horizontal adjustment mechanism 160 drive the rotating mechanism 150 to move smoothly in the horizontal direction, a slide rail 1411 is provided on the mounting seat 141, and a slider 16311 is provided at the bottom of the fixing member 1631. The slider 16311 is slidably connected relative to the slide rail 1411, so that when the first driving member 161 drives the rotating mechanism 150 to move in the horizontal direction, it can move along the slider 16311 to ensure stability.

[0064] In addition, the slide rail 1411 and the first driving member 161 in this embodiment are arranged in parallel, and both are perpendicular to the extending direction of the predetermined track 110 .

[0065] See also Figure 5 The unlocking mechanism 170 is provided on the rotating mechanism 150. The unlocking mechanism 170 includes a mounting shaft 171, a fifth driving member 172, and an unlocking member 173. The fifth driving member 172 may be a cylinder. The mounting shaft 171 is connected to the support member 151. The unlocking member 173 rises under the drive of the fifth driving member 172, thereby releasing the locked state of the battery pack on the vehicle chassis.

[0066] In one embodiment of the present invention, the battery replacement device 100 includes four mounting shafts 171, and each mounting shaft is provided with a fifth driving member 172 and an unlocking member 173 at both ends.

[0067] The usage process of the above-mentioned battery replacement equipment 100 is as follows: park the car in a direction perpendicular to the track 110, and place the low-charge battery pack above the rotating mechanism 150, adjust the rotating mechanism 150 so that the eight unlocking parts 173 are aligned with the locking mechanism of the car, then turn on the lifting mechanism 140, lift the rotating mechanism 150 and the horizontal adjustment mechanism 160 on the mounting seat 141, and enable the unlocking mechanism 170 to dismantle the low-charge battery pack, and the low-charge battery pack is supported by the support part 151 of the rotating mechanism 150. After the disassembly is completed, the lifting mechanism 140 lowers the mounting seat 141 back to its original position. At this time, the traveling mechanism 130 drives the rotating mechanism 150, the horizontal adjustment mechanism 160, the two lifting seats 142 and the low-charge battery pack on the base 120 to move out from under the car chassis on the predetermined track 110, thereby removing the low-charge battery pack from under the car chassis. After being transported out and replaced with a fully-charged battery pack, the travel mechanism 130 drives the rotating mechanism 150, the horizontal adjustment mechanism 160, the two lifting seats 142 and the fully-charged battery on the base 120 to move back to the position of the car chassis on the predetermined track 110. The horizontal adjustment mechanism 160 adjusts the rotating mechanism 150 and the fully-charged battery in the horizontal direction. The rotating mechanism 150 drives the fully-charged battery to rotate, and the lifting mechanism 140 drives the fully-charged battery pack to rise. When the fully-charged battery pack hits the slider of the locking mechanism on the car chassis, the slider contracts; the fully-charged battery pack continues to rise. At this time, the fully-charged battery pack is dislocated and disengaged from the slider, and there is no interaction force between the two. The slider of the car's locking mechanism extends out under the action of the spring to support the fully-charged battery pack, thereby achieving locking. In this way, the installation of the fully-charged battery is achieved, and the replacement between the depleted battery and the fully-charged battery is achieved.

[0068] The above-mentioned battery replacement device 100, the base 120, the lifting mechanism 140, the rotating mechanism 150, the horizontal adjustment mechanism 160 and the unlocking mechanism 170 are integrated into one, with a compact layout and high integration, which reduces the land space. The battery replacement device 100 has strong compatibility. To cope with different car models, it is only necessary to change the unlocking mechanism 170 to achieve unlocking of the batteries of different cars. It is easy to operate and low cost.

[0069] See also Figure 6 In a second embodiment, the present invention further provides a battery replacement system 200, comprising a battery warehouse 210 and the above-mentioned battery replacement device 100, wherein the battery replacement device 100 is used to transfer batteries between a battery replacement site and the battery warehouse 210.

[0070] In addition, the battery swap system 200 also includes a carrier 220 for supporting the vehicle. To achieve more precise alignment between the vehicle 300 and the rotation mechanism 150 and the horizontal adjustment mechanism 160 of the battery swap device 100, a sensor and a driver may be mounted on the carrier 220. The sensor senses the position of the vehicle 300 on the carrier, and the driver drives the carrier 220 to adjust its position, thereby aligning the vehicle 300.

[0071] Because the track 110 and the battery storage 210 are coaxial, it is understandable that the parking position of the vehicle 300 is perpendicular to the direction of the battery storage 210. Therefore, after the depleted battery is removed, it is perpendicular to the direction of the battery storage 210. Therefore, the depleted battery pack needs to be rotated 90 degrees to correspond to the orientation of the battery storage 210. The 90-degree rotation of the depleted battery pack is performed by the rotation mechanism 150.

[0072] It is understandable that after the traveling mechanism 130 drives the base 120 to transport the fully charged battery pack back, the rotating mechanism 150 needs to rotate the fully charged battery pack 90 degrees before installing it on the vehicle chassis.

[0073] The above-mentioned battery replacement system 200 includes a battery replacement device 100 and a battery warehouse 210, so that the battery replacement device 100 can directly transfer batteries between the battery replacement site and the battery warehouse 210 without the need to set up other transfer equipment. A carrier rack 220 is provided to perform initial positioning of the car, which facilitates the positioning of the battery pack.

[0074] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
