Description

Technical Field

[0001] This invention relates to the field of battery technology, and in particular to a conveying device. Background Technology

[0002] In the assembly process of power battery packs, many steps involve the transfer and loading of battery packs. Currently, this relies heavily on manual labor to place the battery packs into the battery racks, resulting in low efficiency, high risk, and wasted human resources. Some related technologies employ automated assembly lines that use conveyor equipment to transport battery packs to the racks. However, the conveyor equipment in these technologies is limited by its own structure, leading to weak structural rigidity and poor stability during battery pack transport. Therefore, this issue needs to be addressed. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a conveying device that divides the conveying path of a battery pack into a first stroke conveyed by a first conveying mechanism and a second stroke conveyed by a second conveying mechanism, such that both the first and second conveying mechanisms have high structural rigidity, which can effectively improve the stability of the battery pack during the conveying process and reduce or avoid the decrease in stability of the battery pack conveying process due to insufficient rigidity of the first or second conveying mechanism.

[0004] According to an embodiment of the present invention, a conveying device includes: a frame; a support mechanism disposed on the frame and used to carry a battery pack; and a conveying assembly disposed on the frame and used to convey the battery pack to a battery rack along a first direction, the first direction being perpendicular to the vertical direction. The conveying assembly includes a first conveying mechanism and a second conveying mechanism. The first conveying mechanism is used to convey the battery pack along the first direction from a first position to a second position for a first stroke, and the second conveying mechanism is used to convey the battery pack along the first direction from the second position to a second stroke into the battery rack. During the second stroke, a portion of the second conveying mechanism extends out of the frame along the first direction, and at least a portion of the battery pack is located outside the frame.

[0005] According to embodiments of the present invention, the conveying device includes a frame, a support mechanism, and a conveying component. By using the conveying component to convey the battery pack along a first direction to the battery rack, an automated conveying process for the battery pack can be achieved. This reduces manpower input, is more labor-saving, and improves the conveying efficiency of the battery pack, thereby increasing the overall production efficiency of the production line. Furthermore, by including a first conveying mechanism and a second conveying mechanism, where the first conveying mechanism conveys the battery pack along the first direction from a first position for a first stroke to a second position, and the second conveying mechanism conveys the battery pack along the first direction from the second position for a second stroke into the battery rack, the conveying efficiency of the battery pack can be improved. The conveying path is divided into a first stroke conveyed by a first conveying mechanism and a second stroke conveyed by a second conveying mechanism. The first conveying mechanism is located inside the frame to complete the short-distance transfer of the battery pack from the first position to the second position inside the frame. Part of the second conveying mechanism extends outside the frame to complete the transfer of the battery pack from the second position to the inside of the battery rack. This can effectively shorten the extension length of a single conveying mechanism, making the structural rigidity of both the first and second conveying mechanisms stronger. This can effectively improve the stability of the battery pack during the conveying process and reduce or avoid the decrease in stability of the battery pack during the conveying process due to insufficient rigidity of the first or second conveying mechanism.

[0006] In addition, by extending part of the second conveying mechanism outside the frame, the second stroke of the battery pack can be completed and the entire battery pack can be conveyed into the battery rack. By extending part of the second conveying mechanism outside the frame in the first direction, the battery pack can be moved onto the battery rack more stably. It can also reduce the alignment accuracy requirements between the conveying equipment and the battery rack. For example, the part of the second conveying mechanism extending outside the frame can compensate for the gap between the conveying equipment and the battery rack, which is beneficial to improving the fault tolerance of the conveying equipment.

Detailed Implementation

[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The following is for reference. Figures 1-12 A conveying device 100 according to an embodiment of the present invention is described.

[0027] Reference Figures 3-5 According to an embodiment of the present invention, the conveying device 100 includes a frame 1, a support mechanism 2 and a conveying component 3. The support mechanism 2 is disposed on the frame 1 and is used to carry the battery pack. The conveying component 3 is disposed on the frame 1 and is used to convey the battery pack to the battery rack 200 along a first direction (for example, the e1 direction in the figure). The first direction is perpendicular to the vertical direction.

[0028] The frame 1 serves as the mounting carrier for the support mechanism 2 and the conveying assembly 3, providing support and fixation for them. The support mechanism 2 carries the battery pack, facilitating its placement on the conveying equipment 100. By having the conveying assembly 3 transport the battery pack along the first direction to the battery rack 200, the battery pack can be moved along the first direction to transfer from the frame 1 to the battery rack 200.

[0029] For example, compared to manually carrying battery packs to the battery rack 200, by having the conveying component 3 transport the battery packs to the battery rack 200 along the first direction, the conveying efficiency can be improved, the manpower input can be reduced, and the effort can be saved, which is conducive to improving the production efficiency of the production line.

[0030] The conveying assembly 3 includes a first conveying mechanism 31 and a second conveying mechanism 32. The first conveying mechanism 31 is used to convey the battery pack from a first position to a second position along a first direction for a first stroke. The second conveying mechanism 32 is used to convey the battery pack from the second position to the battery rack 200 along the first direction for a second stroke. In the second stroke, a portion of the second conveying mechanism 32 extends out of the rack 1 along the first direction, and at least a portion of the battery pack is located outside the rack 1.

[0031] The fact that at least a portion of the battery pack is located outside the rack 1 can include the following situations: for example, a portion of the battery pack may be located outside the rack 1; or, for another example, the entire battery pack may be located outside the rack 1.

[0032] By including a first conveying mechanism 31 and a second conveying mechanism 32 in the conveying assembly 3, where the first conveying mechanism 31 is used to convey the battery pack from a first position to a second position along a first direction for a first stroke, and the second conveying mechanism 32 is used to convey the battery pack from the second position to the battery rack 200 along the first direction for a second stroke, the conveying path of the battery pack can be divided into a first stroke conveyed by the first conveying mechanism 31 and a second stroke conveyed by the second conveying mechanism 32. In the first stroke, the battery pack is moved from the first position to the second position by the first conveying mechanism 31 to complete a short-distance transfer of the battery pack on the rack 1, and in the second stroke... The process involves moving the battery pack from the second position to outside the frame 1 and completely transferring it into the battery rack 200 via the second conveying mechanism 32. This completes the process of moving the battery pack from the frame 1 to the battery rack 200. By dividing the battery pack's transport path into a first stroke by the first conveying mechanism 31 and a second stroke by the second conveying mechanism 32, both the first and second conveying mechanisms 31 and 32 have strong structural rigidity. This effectively improves the stability of the battery pack transport process and reduces or avoids the decrease in stability caused by insufficient rigidity of the first or second conveying mechanism 31 or 32.

[0033] For example, if only a single conveying mechanism is used to transport the battery pack, the extension length of this single conveying mechanism along the first direction is too large, especially the push rod 322, which needs to be fed over a long distance. For example, the part extending outside the frame 1 is too far from the drive point. The excessive extension reduces the bending resistance of the push rod 322, resulting in a rigid structure of the single conveying mechanism and weak rigidity. During the transport of the battery pack, it is prone to shaking and other issues, affecting the transport stability of the battery pack. By dividing the transport path of the battery pack into a first stroke by the first conveying mechanism 31 and a second stroke by the second conveying mechanism 32, the segmented transport layout can optimize the stress conditions of the two conveying mechanisms respectively, improve the structural rigidity of the first conveying mechanism 31 and the second conveying mechanism 32, and in the second stroke stage, only a part of the second conveying mechanism 32 needs to extend outside the frame 1 to push at least a part of the battery pack into the battery rack 200. This makes the part extending outside the frame 1 closer to the drive point, which can make the battery pack transport condition more stable and effectively avoid the problem of instability during battery pack transport caused by insufficient rigidity of the conveying mechanism.

[0034] For example, compared to a single conveying mechanism extending outside the frame 1 to transport the battery pack into the battery rack 200, the excessively large size of the extended section of a single conveying mechanism results in a large load on the extended section outside the frame 1, which can easily lead to insufficient support strength and poor transport stability of the battery pack. By dividing the transport path of the battery pack into a first stroke transported by the first conveying mechanism 31 and a second stroke transported by the second conveying mechanism 32, the first conveying mechanism 31 is located inside the frame 1 to complete the short-distance transfer of the battery pack from the first position to the second position within the frame 1, and a portion of the second conveying mechanism 32 extends outward to complete the second stroke transport of the battery pack from the second position into the battery rack 200. This effectively shortens the extension length of a single conveying mechanism, effectively reduces the load on the extended section, and thus improves the overall support rigidity and structural rigidity of the conveying assembly 3, which is beneficial to improving the transport stability of the battery pack.

[0035] Furthermore, in the second stroke, by extending a portion of the second conveying mechanism 32 outside the frame 1 in the first direction, at least a portion of the battery pack located outside the frame 1 can be moved onto the battery rack 200, thereby moving the entire battery pack onto the battery rack 200. For example, when part of the battery pack is located on the frame 1 and another part is located on the battery rack 200, the entire battery pack can be conveyed onto the battery rack 200 by extending a portion of the second conveying mechanism 32 outside the frame 1 in the first direction. As another example, when there is a gap between the battery rack 200 and the conveying device 100 due to alignment deviation, extending a portion of the second conveying mechanism 32 outside the frame 1 in the first direction can effectively compensate for this gap, allowing the entire battery pack to be moved onto the battery rack 200. This effectively reduces the alignment accuracy requirements between the conveying device 100 and the battery rack 200, and improves the fault tolerance of the conveying device 100.

[0036] According to an embodiment of the present invention, the conveying device 100 includes a frame 1, a support mechanism 2, and a conveying component 3. The conveying component 3 conveys the battery pack along a first direction to the battery rack 200, thus achieving an automated conveying process for the battery pack. This reduces manpower input, is more labor-saving, and improves the conveying efficiency of the battery pack, thereby increasing the overall production efficiency of the production line. Furthermore, by including a first conveying mechanism 31 and a second conveying mechanism 32, the first conveying mechanism 31 conveys the battery pack along the first direction from a first position for a first stroke to a second position, and the second conveying mechanism 32 conveys the battery pack along the first direction from the second position for a second stroke into the battery rack 200. This allows the battery pack to be conveyed more efficiently. The conveying path is divided into a first stroke conveyed by the first conveying mechanism 31 and a second stroke conveyed by the second conveying mechanism 32. The first conveying mechanism 31 is located inside the frame 1 to complete the short-distance transfer of the battery pack from the first position to the second position inside the frame 1. Part of the second conveying mechanism 32 extends out of the frame 1 to complete the transfer of the battery pack from the second position to the battery rack 200. This can effectively shorten the extension length of a single conveying mechanism, making the structural rigidity of both the first conveying mechanism 31 and the second conveying mechanism 32 stronger. This can effectively improve the stability of the battery pack during the conveying process and reduce or avoid the decrease in the stability of the battery pack during the conveying process due to insufficient rigidity of the first conveying mechanism 31 or the second conveying mechanism 32.

[0037] In addition, by extending part of the second conveying mechanism 32 outside the frame 1, the second stroke of the battery pack can be completed and the entire battery pack can be conveyed into the battery rack 200. By extending part of the second conveying mechanism 32 outside the frame 1 in the first direction, the battery pack can be moved onto the battery rack 200 more stably. This also reduces the alignment accuracy requirements between the conveying device 100 and the battery rack 200. For example, the part of the second conveying mechanism 32 extending outside the frame 1 can compensate for the gap between the conveying device 100 and the battery rack 200, which helps to improve the fault tolerance of the conveying device 100.

[0038] Reference Figure 3 , Figure 5 , Figure 6 and Figure 8 According to some embodiments of the present invention, the length of the first stroke is greater than the length of the second stroke.

[0039] Since at least a portion of the battery pack is located outside the frame 1 during the second stroke, by extending a portion of the second conveying mechanism 32 outside the frame 1, at least a portion of the battery pack is completely pushed into the battery rack 200. By making the length of the first stroke greater than the length of the second stroke, and since the entire first conveying mechanism 31 is located inside the frame 1, the frame 1 can provide stable support for the first conveying mechanism 31 and the battery pack. This allows most of the battery pack's conveying stroke to be completed by the first conveying mechanism 31 located inside the frame 1, making the battery pack move more stably inside the frame 1. It also allows the extension length of the second conveying mechanism 32 along the first direction to be smaller, and correspondingly, the length of the portion of the second conveying mechanism 32 extending outside the frame 1 to be smaller. This effectively reduces the bending moment of the portion of the second conveying mechanism 32 extending outside the frame 1, giving the second conveying mechanism 32 a stronger overall structural rigidity. This avoids the second conveying mechanism 32 becoming too weak in structural rigidity due to excessive length extending outside the frame 1, which is beneficial for improving the stability of the battery pack during the conveying process.

[0040] For example, there is no auxiliary support mechanism under the part of the second conveying mechanism 32 that extends outside the frame 1, meaning that this part of the second conveying mechanism 32 that extends outside the frame 1 is in a suspended state. By making this part shorter, the stress load on this part can be reduced, the bending resistance of the second conveying mechanism 32 can be improved, and the structural rigidity of the second conveying mechanism 32 can be made higher. In this way, while allowing part of the second conveying mechanism 32 to extend outside the frame 1 to transport the battery pack completely to the battery rack 200, the second conveying mechanism 32 as a whole can have strong structural rigidity, reducing the swaying or shaking of the second conveying mechanism 32 during the transport process, which is conducive to improving the stability of the battery pack during the transport process.

[0041] Reference Figure 5 , Figure 8 and Figure 9 According to some embodiments of the present invention, the first conveying mechanism 31 includes a first drive motor, a lead screw 312 and a first drive block 313. For example, the first drive motor is a servo motor.

[0042] The lead screw 312 extends along a first direction and is rotatably mounted on the frame 1. The first drive motor is mounted on the frame 1 and is connected to the lead screw 312 for driving the lead screw 312 to rotate. The first drive block 313 is sleeved on the outer periphery of the lead screw 312 and is threadedly connected to the lead screw 312. The first drive block 313 is used to cooperate with the battery pack to push the battery pack to move along the first direction.

[0043] By including a first drive motor, a lead screw 312, and a first drive block 313 in the first conveying mechanism 31, with the first drive motor being connected to the lead screw 312 and the lead screw 312 being connected to the first drive block 313, the first drive motor can drive the lead screw 312 to move. The movement of the lead screw 312 can drive the first drive block 313 to move. By extending the lead screw 312 along a first direction and threadedly connecting the lead screw 312 to the first drive block 313, the movement of the lead screw 312 can drive the first drive block 313 to reciprocate along the first direction, so that the first drive block 313 pushes the battery pack to move along the first direction, thereby realizing the process of the first conveying mechanism 31 pushing the battery pack to convey a first stroke from a first position to a second position along the first direction.

[0044] Reference Figure 5 , Figure 8 and Figure 9 According to some embodiments of the present invention, a first guide mechanism 33 is also included. The first guide mechanism 33 is disposed on the frame 1 and includes two guide rails 331. The guide rails 331 extend along a first direction. The two guide rails 331 are located on both sides of the lead screw 312 along a second direction (for example, refer to the e2 direction in the figure). The bottom of the first drive block 313 is provided with two guide grooves 3131. The two guide grooves 3131 are located on both sides of the lead screw 312 along the second direction. The two guide grooves 3131 are slidably engaged with the two guide rails 331 respectively. The first direction, the second direction and the up and down direction are perpendicular to each other.

[0045] The frame 1 can support and fix the first guide mechanism 33. By setting the first guide mechanism 33 on the frame 1 and including a guide rail 331 extending along the first direction, the bottom of the first drive block 313 is provided with a guide groove 3131 that slides with the guide rail 331. The limiting cooperation between the guide rail 331 and the guide groove 3131 can guide and limit the movement of the first drive block 313, so that the first drive block 313 moves more stably along the first direction, reducing or avoiding the possibility of the first drive block 313 deviating.

[0046] Furthermore, by including two guide rails 331 on both sides of the lead screw 312 along the second direction, and two guide grooves 3131 on both sides of the lead screw 312 along the second direction, the space in the second direction can be fully utilized. The lead screw 312 on both sides of the lead screw along the second direction can play a bidirectional limiting role on the first drive block 313, so that the first drive block 313 moves more stably along the first direction, effectively preventing the first drive block 313 from deviating along the second direction. It can also distribute the load applied by the first drive block 313 more evenly, so that the force distribution of the two first guide rails 331 is more uniform, reducing or avoiding the possibility of deformation or even damage of a single guide rail 331 due to excessive force.

[0047] Reference Figure 5 , Figure 6 , Figure 8 and Figure 11 According to some embodiments of the present invention, the second conveying mechanism 32 includes a second drive motor 321 and a push rod 322. The push rod 322 extends along a first direction. The second drive motor 321 is tractively connected to the push rod 322 for driving the push rod 322 to move along the first direction. The push rod 322 is used to push the battery pack to move along the first direction. In the second stroke, a portion of the push rod 322 extends out of the frame 1 along the first direction.

[0048] By including a second drive motor 321 and a push rod 322 in the second conveying mechanism 32, and driving the second drive motor 321 and the push rod 322 in a transmission connection, the second drive motor 321 can drive the push rod 322 to reciprocate along the first direction, and push the battery pack to move along the first direction through the push rod 322, thereby realizing the process of the second conveying mechanism 32 pushing the battery pack to transport the second stroke from the second position to the battery rack 200 along the first direction.

[0049] In the second stroke, by extending a portion of push rod 322 out of the frame 1 in the first direction, the portion of push rod 322 outside the frame 1 can continue to push at least a portion of the battery pack outside the frame 1 into the battery pack, so as to push the entire battery pack into the battery rack 200.

[0050] For example, the second drive motor 321 is a linear electric cylinder. The linear electric cylinder can directly output linear extension and retraction power along the first direction without the need for additional transmission mechanism conversion. The linear electric cylinder has a relatively fast pushing response and can drive the push rod 322 to extend smoothly to the outside of the frame 1 with relatively accurate control, so as to push the battery pack relatively stably.

[0051] For example, refer to Figure 12 A connecting block 325 is provided between the output end of the second drive motor 321 and the push rod 322. The connecting block 325 includes a first connecting part 3251 and a second connecting part 3252 connected together. The first connecting part 3251 extends in the vertical direction and is connected to the output end of the second drive motor 321. The second connecting part 3252 extends in the first direction and is located at the upper end of the first connecting part 3251. The second connecting part 3252 is connected to the push rod 322 and is located above the push rod 322. A limiting groove 3253 is formed on the lower side of the second connecting part 3252, and a portion of the push rod 322 is accommodated in the limiting groove 3253.

[0052] By making the connecting block 325 include a first connecting portion 3251 and a second connecting portion 3252 connected together, and by making the first connecting portion 3251 connected to the output end of the second drive motor 321, the connection area between the second drive motor 321 and the connecting block 325 can be made larger, which is beneficial to enhancing the connection strength between the output end of the second drive motor 321 and the connecting block 325.

[0053] By connecting the second connecting part 3252 to the push rod 322 and positioning it above the push rod 322, the space in the vertical direction can be fully utilized to achieve the connection between the connecting block 325 and the push rod 322. It can also limit the push rod 322 in the vertical direction to prevent it from shifting upwards. Furthermore, by forming a limiting groove 3253 on the second connecting part 3252, a portion of the push rod 322 is accommodated within the limiting groove 3253. This makes the assembly between the push rod 322 and the second connecting part 3252 more convenient and also makes the overall structure of the second connecting part 3252 and the push rod 322 more compact.

[0054] By including a first connecting part 3251 and a second connecting part 3252 connected together in the connecting block 325, and connecting the first connecting part 3251 to the output end of the second drive motor 321 and connecting the second connecting part 3252 to the push rod 322, the connecting block 325 enables the transmission connection between the output end of the second drive motor 321 and the push rod 322, while the connecting block 325 enables the connection area between the output end of the second drive motor 321 and the push rod 322 to be larger, thereby effectively improving the connection strength between the output end of the second drive motor 321 and the push rod 322. In addition, the connecting block 325 can also limit the push rod 322 in the vertical direction, reducing or preventing the push rod 322 from shifting in the vertical direction.

[0055] Reference Figure 6 and Figure 11 According to some embodiments of the present invention, the push rod 322 includes a rod body 3221 and a second drive block 3222. The rod body 3221 extends along a first direction. One end of the rod body 3221 is connected to a second drive motor 321 for transmission. The second drive block 3222 is rotatably connected to the other end of the rod body 3221. The second drive block 3222 is rotatable between a pushing position and a yielding position. In the first stroke, the second drive block 3222 is located in the yielding position, and the highest point of the second drive block 3222 is not higher than the highest point of the support mechanism 2. In the second stroke, the second drive block 3222 is located in the pushing position. The second drive block 3222 is used to cooperate with the battery pack to push the battery pack to move along the first direction.

[0056] By including a rod body 3221 and a second drive block 3222 in the push rod 3222, one end of the rod body 3221 is connected to the second drive motor 321 for transmission, and the second drive block 3222 is rotatably connected to the other end of the rod body 3221. The second drive block 3222 can rotate between a pushing position and a yielding position. This allows the position of the second drive block 3222 to be adjusted according to the stroke information of the battery pack. In the first stroke, by positioning the second drive block 3222 in the yielding position and ensuring that the highest point of the second drive block 3222 is not higher than the highest point of the support mechanism 2, the battery pack is transported from the first position to the first stroke on the frame 1. During the process of moving to the second position, the movement can be relatively smooth, effectively avoiding interference between the second drive block 3222 and the battery pack. In the second stroke, by placing the second drive block 3222 in the pushing position, the second drive block 3222 can cooperate with the battery pack to push the battery pack along the first direction from the second position to the battery rack 200. Furthermore, by cooperating with the battery pack, the second drive block 3222 has a large contact area with the battery pack, which can better disperse the pushing force of the second conveying mechanism 32 on the battery pack during the conveying process, avoiding excessive local force concentration and deformation of the battery pack.

[0057] Reference Figure 11 In some embodiments, the second conveying mechanism 32 further includes a support base 326. The support base 326 is disposed on the frame 1 and located at the end of the rod 3221 away from the second drive motor 321 along the first direction. Part of the rod 3221 is supported on the support base 326. The support base 326 can support the rod 3221 and also limit the rod 3221 in the up and down direction, reducing or preventing the rod 3221 from moving downward, so that the rod 3221 moves more stably along the first direction during the conveying process.

[0058] For example, the support base 326 includes multiple supports 326, which are arranged at intervals along the extension direction of the rod 3221. This can distribute the load applied by the rod 3221 to the support base 326 more evenly, and the rod 3221 can also play a multi-point support role along the extension direction of the rod 3221. This helps to improve the support effect of the support base 326 on the rod 3221, so that the rod 3221 can move more stably along the first direction during the conveying process.

[0059] For example, a support groove is formed on the support base 326, in which part of the rod 3221 is accommodated. This makes the assembly between the rod 3221 and the support base 326 more convenient, and also makes the overall structure of the support base 326 and the rod 3221 more compact. It can also limit the rod 3221 along the second direction, so that the rod 3221 moves more stably along the first direction, reducing or avoiding the rod 3221 from deviating along the second direction.

[0060] Reference Figure 11 In some embodiments, the push rod 322 further includes a mounting portion 327, which is located on the upper side of the rod body 3221 and at one end of the rod body 3221 along a first direction near the second drive block 3222. The mounting portion 327 has a mounting groove, in which a portion of the second drive block 3222 and the rotating shaft 3224 are accommodated. The sidewall of the mounting groove has a mounting hole for avoiding the rotating shaft 3224. By accommodating a portion of the second drive block 3222 and the rotating shaft 3224 in the mounting groove, the assembly of the second drive block 3222 and the rotating shaft 3224 on the rod body 3221 is more convenient, and the overall structure of the second drive block 3222 and the mounting portion 327 is more compact, resulting in a smaller space occupied by the second drive block 3222 and the mounting portion 327.

[0061] Reference Figure 6 and Figure 11 According to some embodiments of the present invention, the rotation axis of the second drive block 3222 extends along the second direction, and the first direction, the second direction and the up and down direction are perpendicular to each other. The second drive block 3222 includes a drive surface 3223, which contacts and cooperates with the battery pack. In the first stroke, the drive surface 3223 faces downward, and in the second stroke, the drive surface 3223 faces the first direction.

[0062] By extending the rotation axis of the second drive block 3222 along the second direction, the second drive block 3222 can rotate in the vertical direction. In the first stroke, by making the drive surface 3223 face downward, the highest point of the second drive block 3222 can be no higher than the highest point of the support mechanism 2, so that the battery pack can move more smoothly and effectively avoid interference between the second drive block 3222 and the battery pack. In the second stroke, by making the drive surface 3223 face the first direction, the orientation of the drive surface 3223 can be consistent with the conveying direction of the battery pack, so that the second drive block 3222 can cooperate with the battery pack to push the battery pack to move along the first direction.

[0063] For example, the second drive block 3222 is formed in an "L" shape. When the second drive block 3222 is in the avoidance position, the "L"-shaped second drive block 3222 has an avoidance space for avoiding the rod 3221, so that the overall structure of the second drive block 3222 and the rod 3221 is more compact, reducing the space occupied by the second drive block 3222 and the rod 3221 as a whole.

[0064] Reference Figure 6 and Figure 11According to some embodiments of the present invention, the second conveying mechanism 32 includes a limiting cover 323, which covers the outside of the second conveying mechanism 32, and the limiting cover 323 is open on one side along a first direction to form an opening. By including the limiting cover 323 on the outside of the second conveying mechanism 32, the limiting cover 323 can protect the second conveying mechanism 32, reducing or avoiding the possibility of damage to the second conveying mechanism 32 caused by external impacts, etc.

[0065] By opening the limiting cover 323 on one side along the first direction to form an opening, it is possible for at least a portion of the second drive block 3222 and the rod 3221 to extend out of the limiting cover 323 or enter the limiting cover 323 from the opening.

[0066] In the first stroke, both the second drive block 3222 and the rod 3221 are located inside the limiting cover 323. In the second stroke, the second drive block 3222 extends out of the limiting cover 323 through an opening. During the first stroke, by keeping both the second drive block 3222 and the rod 3221 inside the limiting cover 323, the limiting cover 3222 and the rod 3221 are positioned and protected, ensuring that the highest point of the second drive block 3222 is not higher than the highest point of the support mechanism 2, thus effectively preventing interference between the second drive block 3222 and the battery pack. Furthermore, during the second stroke, by allowing the second drive block 3222 to extend out of the limiting cover 323 through the opening, the limiting effect of the limiting cover 323 on the second drive block 3222 is released, allowing the second drive block 3222 to move to the pushing position.

[0067] Reference Figure 6 and Figure 11 According to some embodiments of the present invention, the second conveying mechanism 32 further includes an elastic reset member 324, which is sleeved on the rotating shaft 3224 of the second driving block 3222. During the process of the second driving block 3222 moving through the opening into the limiting cover 323, the limiting cover 323 is used to press the second driving block 3222 downward so that the second driving block 3222 rotates to the avoidance position. During the process of the second driving block 3222 moving from the opening to the outside of the limiting cover 323, the elastic reset member 324 is used to drive the second driving block 3222 to rotate to the pushing position.

[0068] By including an elastic reset member 324 in the second conveying mechanism 32, which is sleeved on the rotating shaft 3224 of the second drive block 3222, the elastic restoring force of the elastic reset member 324 can be used to drive the second drive block 3222 to rotate to the pushing position during the process of the second drive block 3222 moving from the opening to the outside of the limiting cover 323.

[0069] During the process of the second drive block 3222 moving into the limiting cover 323 through the opening, the limiting cover 323 applies downward pressure to the second drive block 3222, causing the second drive block 3222 to rotate from the pushing position to the avoiding position. During the process of the second drive block 3222 moving out of the limiting cover 323 from the opening, the elastic restoring force of the elastic reset member 324 causes the second drive block 3222 to move from the avoiding position to the pushing position. This makes the structure of the drive mechanism used to drive the second drive block 3222 to rotate between the avoiding position and the pushing position relatively simple, which simplifies the overall structure of the second conveying mechanism 32, reduces the number of parts, and helps to reduce manufacturing costs.

[0070] For example, during the process of the second drive block 3222 moving into the limiting cover 323 through the opening, the limiting cover 323 covers the outside of the second drive block 3222. The limiting effect of the limiting cover 323 on the second drive block 3222 can be used to apply downward pressure to the second drive block 3222, so that the second drive block 3222 rotates downward to the avoidance position. At this time, the pressure applied by the limiting cover 323 on the second drive block 3222 can overcome the elastic force of the elastic reset member 324, and the process of the second drive block 3222 rotating from the pushing position to the avoidance position can be completed.

[0071] For example, during the process of the second drive block 3222 moving from the opening to outside the limiting cover 323, since the limiting cover 323 releases its limiting effect on the second drive block 3222, the elastic restoring force of the elastic reset member 324 drives the second drive block 3222 to rotate to the pushing position, thus completing the process of the second drive block 3222 rotating from the avoidance position to the pushing position.

[0072] In some embodiments, the elastic reset member 324 is a torsion spring, which is sleeved on the outer periphery of the rotating shaft 3224. By making the elastic reset member 324 a torsion spring and sleeved on the outer periphery of the rotating shaft 3224, the torsion spring and the rotating shaft 3224 can be coaxially arranged, and the overall structure of the torsion spring and the rotating shaft 3224 can be compact. Furthermore, the driving force provided by the torsion spring to the second driving block 3222 can drive the second driving block 3222 to rotate in a more stable and efficient manner.

[0073] Reference Figure 6 and Figure 11 According to some embodiments of the present invention, there are two second conveying mechanisms 32, which are arranged at intervals along the second direction, and the first direction, the second direction and the up and down direction are perpendicular to each other.

[0074] By having two second conveying mechanisms 32 spaced apart along the second direction, the contact area between the second conveying mechanism 32 and the battery pack can be increased, and a greater pushing force can be applied to the battery pack, thereby improving the conveying efficiency of the second conveying mechanism 32 to the battery pack. Furthermore, the simultaneous application of pushing force by the two second conveying mechanisms 32 to the battery pack can also make the pushing force more evenly distributed along the second direction, reducing the risk of the battery pack deflecting or tilting due to excessive force on one side, which is beneficial to improving the conveying stability of the battery pack in the second stroke.

[0075] Reference Figure 5 , Figure 6 and Figure 8 According to some embodiments of the present invention, the first conveying mechanism 31 includes a first drive motor, a lead screw 312 and a first drive block 313. The lead screw 312 extends along a first direction and is rotatably mounted on the frame 1. The first drive motor is mounted on the frame 1 and is drivenly connected to the lead screw 312 to drive the lead screw 312 to rotate. The first drive block 313 is sleeved on the outer periphery of the lead screw 312 and is threadedly connected to the lead screw 312. The first drive block 313 is used to cooperate with the battery pack to push the battery pack to move along the first direction. The two second conveying mechanisms 32 are located on both sides of the lead screw 312 in a second direction.

[0076] By arranging the two second conveying mechanisms 32 at intervals along the second direction and placing them on both sides of the lead screw 312 in the second direction, the space in the second direction can be fully utilized, allowing the first conveying mechanism 31 and the second conveying mechanism 32 to be arranged in an orderly manner. This effectively avoids interference between the first conveying mechanism 31 and the second conveying mechanism 32, and also makes the overall structure of the first conveying mechanism 31 and the second conveying mechanism 32 more compact, resulting in a smaller space occupied by the first conveying mechanism 31 and the second conveying mechanism 32. This is beneficial for the miniaturization and layout optimization of the conveying equipment 100 as a whole.

[0077] Reference Figure 5 , Figure 6 and Figure 8 According to some embodiments of the present invention, the support mechanism 2 includes two sets of support roller groups 21, which are arranged at intervals along a second direction. The conveying component 3 is located between the two support roller groups 21. Each set of support roller groups 21 includes a plurality of support rollers 211 arranged at intervals along a first direction. Each support roller 211 is rotatably connected to the frame 1 and the rotation axis of the support roller 211 extends along the second direction. The first direction, the second direction, and the up and down direction are perpendicular to each other.

[0078] By including two sets of support rollers 21 in the support mechanism 2 and arranging them at intervals along the second direction, and placing the conveying component 3 between the two sets of support rollers 21, the space in the second direction can be fully utilized, allowing the conveying component 3 and the support mechanism 2 to be arranged in an orderly manner. This also makes the overall structure of the conveying component 3 and the support mechanism 2 more compact, which is beneficial for the miniaturization of the conveying equipment 100. Furthermore, the two sets of support rollers 21 can distribute the weight of the battery pack more evenly, so that the battery pack is more stably positioned on the support mechanism 2 during the conveying process, which is beneficial for improving the stability of the battery pack conveying process.

[0079] By making each set of support rollers 21 include multiple support rollers 211 spaced apart along a first direction, with each support roller 211 rotatably connected to the frame 1 and the rotation axis of the support roller 211 extending along a second direction, the friction between the battery pack and the support mechanism 2 during the transport process is rolling friction. Compared with sliding friction, rolling friction has less resistance and generates less frictional wear. This can reduce the frictional wear of the battery pack during the transport process, which is beneficial to extending the service life of the support mechanism 2. It can also push the battery pack to move with less force, which is beneficial to reducing the operating power of the first conveying mechanism 31.

[0080] According to some embodiments of the present invention, a position sensor and a controller are also included. The position sensor is disposed on the frame 1 and is used to detect the position information of the battery pack. The controller is electrically connected to the position sensor, the first conveying mechanism 31 and the second conveying mechanism 32, and is used to control the first conveying mechanism 31 and the second conveying mechanism 32 according to the position information of the battery pack.

[0081] The frame 1 can support and fix the position sensor. By including a position sensor and a controller in the conveying device 100, the position sensor can detect the position information of the battery pack more directly and accurately; and by electrically connecting the controller to the position sensor, the first conveying mechanism 31 and the second conveying mechanism 32, information transmission between the controller and the position sensor, and between the first conveying mechanism 31 and the second conveying mechanism 32 can be realized.

[0082] For example, when the position sensor detects that the battery pack is in the first position, the controller can control the first conveying mechanism 31 to drive the battery pack from the first position to the second position by a first stroke, and control the second drive motor 321 to drive the second drive block 3222 to move to the avoidance position via the push rod 322, so as to avoid interference between the second drive block 3222 and the battery pack; as another example, when the position sensor detects that the battery pack is in the second position, the controller can control the second drive motor 321 to drive the second drive block 3222 from the avoidance position to the pushing position via the push rod 322, and transport the battery pack from the second position to the battery rack 200 along the first direction by a second stroke, so as to complete the conveying process of the battery pack.

[0083] For example, a position sensor can be used to detect the position information of the first drive block 313. The position information of the battery pack can also be determined more accurately through the position information of the first drive block 313.

[0084] For example, a position sensor can be installed on the lead screw 312 and used to detect the movement state of the lead screw 312. The position information of the battery pack can also be determined more accurately by the movement state of the lead screw 312.

[0085] Reference Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 According to some embodiments of the present invention, the frame 1 is provided with a first limiting mechanism 13 and a second limiting mechanism 14. The first limiting mechanism 13 and the second limiting mechanism 14 are located on both sides of the support mechanism 2 along the second direction. The first limiting mechanism 13 and the second limiting mechanism 14 both extend along the first direction. The conveying component 3 is disposed between the first limiting mechanism 13 and the second limiting mechanism 14. The first limiting mechanism 13 and the second limiting mechanism 14 are used to limit the battery pack in the second direction. The first direction, the second direction and the up and down direction are perpendicular to each other.

[0086] By positioning the first limiting mechanism 13 and the second limiting mechanism 14 on both sides of the support mechanism 2 along the second direction, and with the conveying component 3 positioned between the first limiting mechanism 13 and the second limiting mechanism 14, the first limiting mechanism 13 and the second limiting mechanism 14 can limit the battery pack located on the support mechanism 2, ensuring that the battery pack is stably positioned on the support mechanism 2 during the conveying process and preventing the battery from falling off the support mechanism 2.

[0087] For example, the first limiting mechanism 13 and the second limiting mechanism 14 can respectively abut against the two sides of the battery pack along the second direction, so that the battery pack is stably positioned on the support mechanism 2 during the transportation process, and the battery is prevented from falling off the support mechanism 2.

[0088] Reference Figure 6, Figure 7 , Figure 8 and Figure 10 According to some embodiments of the present invention, the first limiting mechanism 13 includes a first limiting baffle 131 and a first roller 132. The first roller 132 is disposed on the side of the first limiting baffle 131 near the support mechanism 2, and the first roller 132 is rotatably connected to the first limiting baffle 131. The rotation axis of the first roller 132 extends in the vertical direction. The second limiting mechanism 14 includes a second limiting baffle 141 and a second roller 142. The second roller 142 is disposed on the side of the second limiting baffle 141 near the support mechanism 2, and the second roller 142 is rotatably connected to the second limiting baffle 141. The rotation axis of the second roller 142 extends in the vertical direction.

[0089] By including a first limiting baffle 131 and a first roller 132 in the first limiting mechanism 13, the first limiting baffle 131 can serve as the mounting carrier for the first roller 132, providing support and fixing for the first roller 132.

[0090] By rotatably connecting the first roller 132 to the first limiting baffle 131 and extending the rotation axis of the first roller 132 in the vertical direction, the friction between the first roller 132 and the battery pack can be rolling friction. Compared with sliding friction, rolling friction has less resistance and generates less frictional wear. This allows the first limiting mechanism 13 to limit the battery pack in the second direction during the transport process, while also reducing frictional wear between the battery pack and the first limiting mechanism 13, and enabling the battery pack to move more smoothly in the first direction.

[0091] Accordingly, by making the second limiting mechanism 14 include a second limiting baffle 141 and a second roller 142, the second limiting baffle 141 can serve as a mounting carrier for the second roller 142, and play a supporting and fixing role for the second roller 142.

[0092] By rotatably connecting the second roller 142 to the second limiting baffle 141 and extending the rotation axis of the second roller 142 in the vertical direction, the friction between the second roller 142 and the battery pack can be rolling friction. Compared with sliding friction, rolling friction has less resistance and generates less frictional wear. This allows the second limiting mechanism 14 to limit the battery pack in the second direction during the transport process, while also reducing frictional wear between the battery pack and the second limiting mechanism 14, and enabling the battery pack to move more smoothly in the first direction.

[0093] Reference Figures 5-8According to some embodiments of the present invention, the distance between the first limiting mechanism 13 and the second limiting mechanism 14 along the second direction is adjustable. This allows the distance between the first limiting mechanism 13 and the second limiting mechanism 14 to be adjusted according to different dimensions of the battery pack along the second direction, so that the first limiting mechanism 13 and the second limiting mechanism 14 respectively abut against the two sides of the battery pack along the second direction, thereby effectively limiting the battery pack.

[0094] For example, when the distance between the battery pack and the first limiting mechanism 13 and the second limiting mechanism 14 on both sides along the second direction is large, the second roller 142 can be driven to move toward the side closer to the first limiting mechanism 13 by controlling the limiting drive mechanism 15, so as to reduce the distance between the first limiting mechanism 13 and the second limiting mechanism 14, so that the first limiting mechanism 13 and the second limiting mechanism 14 abut against the battery pack on both sides along the second direction respectively, so as to limit the battery pack.

[0095] For example, if the battery pack is larger in size along the second direction, the second roller 142 can be moved away from the first limiting mechanism 13 by controlling the limiting drive mechanism 15 to increase the distance between the first limiting mechanism 13 and the second limiting mechanism 14, so that the battery pack can be accommodated between the first limiting mechanism 13 and the second limiting mechanism 14, and the battery pack abuts against the first limiting mechanism 13 and the second limiting mechanism 14 on both sides along the second direction, so as to limit the battery pack.

[0096] Reference Figures 5-8 In some embodiments, a limiting drive mechanism 15 is provided on the side of the second limiting baffle 141 away from the support mechanism 2. A connecting rod 151 is provided between the limiting drive mechanism 15 and the second roller 142. The connecting rod 151 extends along the second direction. The operator can operate the limiting drive mechanism 15 to move the second roller 142 according to the actual situation, so as to adjust the distance between the first limiting mechanism 13 and the second limiting mechanism 14 along the second direction.

[0097] For example, the limit drive mechanism 15 is a hand crank, which allows the operator to manually operate the limit drive mechanism 15 and adjust the distance between the first limit mechanism 13 and the second limit mechanism 14 in a timely manner, so that the battery pack is located between the first limit mechanism 13 and the second limit mechanism 14, and the first limit mechanism 13 and the second limit mechanism 14 abut against the opposite sides of the battery pack along the second direction, so as to effectively limit the battery pack; and by positioning the limit drive mechanism 15 on the side of the second limit baffle 141 away from the support mechanism 2, the limit drive mechanism 15 and the support mechanism 2 can be spaced apart along the second direction, effectively avoiding interference between the limit drive mechanism 15 and the battery pack located on the support mechanism 2.

[0098] Furthermore, by making the limit drive mechanism 15 a hand crank, the cost of the hand crank is lower than that of the electric drive limit mechanism, which helps to reduce the overall manufacturing cost of the conveying equipment 100.

[0099] Reference Figures 1-4 According to some embodiments of the present invention, the frame 1 includes a stand 11 and a support frame 12. The support frame 12 is movably disposed on the stand 11. The conveying assembly 3 and the support mechanism 2 are both disposed on the support frame 12. The conveying equipment 100 also includes a lifting drive mechanism 4. The lifting drive mechanism 4 is disposed on the stand 11 and connected to the support frame 12 for driving the support frame 12 to move in the vertical direction.

[0100] The upright frame 11 can serve as the basic carrier for the support frame 12 and the lifting drive mechanism 4. The upright frame 11 can be an integral structure or a combination structure formed by the cooperation of multiple parts. The upright frame 11 can play a role in supporting and protecting other components on the support frame 12. These other components include the conveying assembly 3 and the support mechanism 2, but are not limited to these.

[0101] By connecting the lifting drive mechanism 4 to the support frame 12 to drive the support frame 12 to move in the vertical direction, the moving speed and position of the support frame 12 can be controlled. The support frame 12 can also be positioned at different heights to transport the battery pack to different positions in the vertical direction of the battery rack 200.

[0102] For example, the battery rack 200 includes multiple storage layers arranged sequentially in the vertical direction. The battery pack is stored in the storage layer. Each storage layer contains a battery pack and each storage layer can hold at least one battery pack.
