Description

Technical Field

[0001] The present disclosure relates to the technical field of battery transfer devices, and in particular to a transfer trolley. Background Art

[0002] During the production process of fuel cells, special transport trolleys are required for handling. Due to the booming development of fuel cells and the rapid product updates and iterations, to meet the market demand, the system power of fuel cells has been made larger and larger, and the size of fuel cells has also become correspondingly larger. Although this meets the market demand, the increase in the size of fuel cells has led to the inability of the original trolleys for transporting batteries to meet the transportation of fuel cells of different sizes. If different-sized transport trolleys are respectively matched for fuel cells of different sizes, it will lead to an increase in costs, and the development cycle of different-sized transport trolleys will be lengthened, which is time-consuming and laborious and is not conducive to the transportation of fuel cells.

[0003] Chinese Patent Document CN221162831U discloses a single-cell transfer trolley, including: a vehicle body; a plurality of battery brackets respectively arranged at the top edge of the vehicle body, each of the battery brackets being stepped, and each step surface of the battery bracket being used for lapping the lugs of a single cell; a positioning pin detachably installed on each step surface of the battery bracket. The patent document has the following advantages and effects: The stepped battery brackets are used to lap the lugs of single cells, and a certain number of single cells are lapped to form a single-cell group according to the process for each step. The relative positions of each group of single-cell groups are fixed by positioning pins. The loading of each single-cell group only requires inserting the lugs of the single cell on the corresponding positioning pins. The movement range of the single cell is small, which is convenient for workers to disassemble and assemble. At the same time, the stepped side surface can also abut against the side surface of the lug during transportation, so that the single cell wafers are aligned. Although the above structure can achieve the transportation of batteries, the distance between the middle of its battery brackets is not adjustable, so the transportation of batteries of different sizes cannot be achieved.

[0044] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technologies, methods and devices should be regarded as part of the specification.

[0045] To solve the problem of transporting batteries of different sizes, according to an embodiment of the present application, a transfer cart is provided. The transfer cart of the present application will be introduced in detail below with reference to the accompanying drawings.

[0046] See Figures 1 to 11As shown, according to an embodiment of the present application, a transfer trolley is provided. The transfer trolley is at least used for transferring the battery 3, and the transfer trolley includes a vehicle body 1.

[0047] Wherein, a moving wheel set 2 is arranged at the bottom of the vehicle body 1. The vehicle body 1 includes a first support part 11 and a second support part 12 which are arranged at intervals. The distance between the first support part 11 and the second support part 12 is adjustable, and fixing parts 1121 for adapting to at least two different models of batteries 3 are arranged on both the first support part 11 and the second support part 12. The fixing parts 1121 are used to fix the battery 3 between the first support part 11 and the second support part 12.

[0048] In the present application, the transfer trolley can transfer at least two different models of batteries 3. Different models of batteries 3 are batteries with different sizes. When using the transfer trolley of the present application to transfer the battery 3, first, the operator pushes the transfer trolley to the battery 3 to be transferred. Then, the operator adjusts the distance between the first support part 11 and the second support part 12 of the vehicle body 1 so that the distance between the first support part 11 and the second support part 12 can adapt to the size of the battery 3 to be transferred. Then, the operator can place the battery 3 at the distance between the first support part 11 and the second support part 12 so that the battery 3 can be clamped by the first support part 11 and the second support part 12. And when the battery 3 is clamped between the first support part 11 and the second support part 12, the side of the battery 3 close to the ground will never touch the ground. Then, the battery 3 is fixed on the fixing parts 1121 of the first support part 11 and the second support part 12. As the operator pushes the trolley to the place where the battery 3 is to be placed, the battery 3 can reach the place where the battery 3 is to be placed along with the transfer trolley. Finally, the battery 3 is unloaded from the vehicle body 1 of the transfer trolley, and the transfer of the battery 3 can be completed.

[0049] That is to say, compared with the existing transfer trolley, the transfer trolley of the present application can realize the transfer of batteries of different sizes by setting the first support part 11 and the second support part 12 with adjustable distances.

[0050] In some embodiments, as shown in Figures 1 to 6 As shown, the first support part 11 includes a first bracket 111 and a first support plate 112. Wherein, the first support plate 112 is arranged at the top of the first bracket 111, and the moving wheel set 2 is arranged at the bottom of the first bracket 111; a fixing part 1121 is arranged on one side of the first support plate 112 close to the second support part 12.

[0051] Specifically, the setting of the first support plate 112 enables part of the gravity of the battery 3 to be more evenly distributed to the first support 111. At the same time, the setting of the first support plate 112 also avoids directly setting the fixing part 1121 on the first support 111, thereby solving the problem that some parts on the first support 111 are prone to damage due to stress concentration, and to a certain extent increasing the strength of the first support 111. The application of setting the fixing part 1121 on the first support plate 112 on the side close to the second support part 12 has two significant advantages. One is to facilitate the connection between the battery 3 and the first support 111; the other is to facilitate the cooperation between the first support part 11 and the second support part 12 to carry the battery 3. In addition, the setting of the moving wheel set 2 can change the sliding between the first support 111 and the ground into rolling, which makes it more labor-saving for the operator to use the transfer trolley of the application to transfer the battery 3.

[0052] In some embodiments, referring to Figures 7 to 11 As shown, the first side of the battery 3 includes at least two connecting blocks 31 arranged at intervals. The distances between the connecting blocks 31 of different models of the battery 3 are different. The fixing part 1121 on the first support plate 112 includes a locking area 11211 and a matching area 11212. The locking area 11211 is used to connect with the first connecting block 311 to lock at least one connecting block 31, and the matching area 11212 is used to connect with the second connecting block 312 to connect the remaining connecting blocks 31 to the first support plate 112.

[0053] Specifically, when using the transfer trolley of the application to transfer the battery 3, the operator can first place the first connecting block 311 on the battery 3 at the locking area 11211, and then place the second connecting block 312 on the battery 3 at the matching area 11212. Then, the operator fixes the first connecting block 311 and the second connecting block 312 on the first support plate 112 respectively. Since the transfer trolley is prone to jolting during the transfer of the battery 3, which may cause the connection between the battery 3 and the first support plate 112 to become loose, and then cause the relative position between the battery 3 and the first support plate 112 to change, the application sets the locking area 11211 on the first support plate 112. The setting of the locking area 11211 can prevent the relative position between the battery 3 and the first support plate 112 from changing, which is beneficial to the transfer of the battery 3.

[0054] In some embodiments, referring to Figure 4 and Figure 10 As shown, the locking area 11211 includes a plurality of round holes arranged in sequence along the length direction of the first support plate 112. The first connecting block 311 is locked to the locking area 11211 through a connecting member 4 passing through the round holes.

[0055] Specifically, the length direction of the first support plate 112 is Figure 10 the direction indicated by y in Figure 10 . The circular holes are spaced apart from each other and arranged in sequence along the length direction of the first support plate 112. Such an arrangement enables the locking area 11211 to adapt to connection blocks 31 of batteries of different sizes. In this application, the circular holes at the locking area 11211 can cooperate with the mating area 11212 to limit the relative position between the battery 3 and the first support plate 112, preventing the battery 3 from moving along the length direction of the first support plate 112, and further avoiding damage to the battery 3 due to being knocked during transportation.

[0056] In some embodiments, referring to Figure 4 and Figure 10 as shown in Figure 10 , the mating area 11212 includes a plurality of first long holes. The plurality of first long holes are arranged along the length direction of the first support plate 112, and the plurality of circular holes and the plurality of first long holes are continuously arranged and located at opposite ends of the first support plate 112 respectively, and each first long hole extends along the length direction of the first support plate 112.

[0057] Specifically, the first long holes are spaced apart from each other and arranged in sequence along the length direction of the first support plate 112, and each first long hole has a certain length. Such an arrangement enables the mating area 11212 to adapt to connection blocks 31 of batteries of different sizes. In this application, the first long holes at the mating area 11212 and the circular holes at the locking area 11211 work together to limit the relative position between the battery 3 and the first support plate 112, preventing the battery 3 from moving along the length direction of the first support plate 112, and further avoiding damage to the battery 3 due to being knocked during transportation. When using the transfer cart of this application, first, the first connection block 311 is mated with at least one of the circular holes in the locking area 11211, and then the second connection block 312 is mated with the first long holes at the mating area 11212. Then, the connecting member 4 is inserted into the circular holes and the first long holes respectively to fix the connection between the first support plate 112 and the battery 3.

[0058] In some embodiments, referring to Figure 5 and Figure 10 as shown in Figure 10 , at least one first hollow portion 1122 is provided on the first support plate 112. The first hollow portion 1122 penetrates through the first support plate 112 along the thickness direction thereof.

[0059] Specifically, the thickness direction of the first support plate 112 is Figure 10The direction indicated by x, and the first hollow portion 1122 can be one, two, or more than two. The setting of the first hollow portion 1122 can reduce the use of materials and save manufacturing costs to a certain extent. In addition, the setting of the first hollow portion 1122 can also reduce the weight of the first support plate 112, thereby reducing the gravity on the first support 111 and the moving wheel set 2, and increasing the service life of the first support 111 and the moving wheel set 2. In this embodiment, there are four first hollow portions 1122, and along the length direction of the first support plate 112, two adjacent first hollow portions 1122 are arranged at a certain interval.

[0060] In some embodiments, referring to Figure 4 and Figure 6 as shown, the second support portion 12 is independently provided from the first support portion 11, and the second support portion 12 includes a second support 121 and a second support plate 122. The second side of the battery 3 includes at least two spaced connection blocks 31, and the spacing between the connection blocks 31 of different models of the battery 3 is different.

[0061] Among them, the second support plate 122 is provided on the top of the second support 121, and the moving wheel set 2 is provided at the bottom of the second support 121; a fixing portion 1121 is provided on one side of the second support plate 122 close to the first support portion 11, and the fixing portion 1121 is used to connect with the connection block 31 on the second side of the battery 3 to connect the remaining battery 3 to the second support plate 122.

[0062] Exemplarily, this embodiment shows the case where the second side of the battery 3 includes two spaced connection blocks 31. The function of the second support plate 122 is similar to that of the first support plate 112, and the setting of the second support plate 122 can also increase the strength of the second support 121. When using the transfer trolley of the present application to transfer the battery 3, after the operator fixes the first side of the battery 3 on the first support portion 11, then the connection block 31 on the second side of the battery 3 can be connected and fixed to the fixing portion 1121 on the second support plate 122. With the cooperation of the second support portion 12 and the first support portion 11, batteries 3 of different sizes can be fixed on the transfer trolley and transferred to the place where the battery 3 is to be placed.

[0063] In some embodiments, referring to Figure 4 、 Figure 10 and Figure 11 as shown, the fixing portion 1121 on the second support plate 122 includes a plurality of second long holes.

[0064] Among them, the plurality of long holes are arranged along the length direction of the second support plate 122, and the plurality of second long holes all extend along the length direction of the second support plate 122; the second long holes are used to connect with the connection block 31 on the second side of the battery 3.

[0065] Specifically, the length direction of the second support plate 122 is Figure 11 the direction indicated by z. In this application, there is a certain distance between adjacent two second long holes. The structure of the second support plate 122 is different from that of the first support plate 112. The fixing part 1121 of the first support plate 112 includes a plurality of round holes and a plurality of first long holes, while the fixing part 1121 of the second support plate 122 includes a plurality of second long holes. When using the transfer cart of this application, after the operator fixes the first side of the battery 3 on the first support part 11, aligns the connection holes on the connection block 31 on the second side of the battery 3 with the corresponding second long holes on the second support plate 122, and finally inserts the connectors 4 into the second long holes aligned with the connection holes on the connection block 31 respectively to connect and fix the second side of the battery 3 on the second support plate 122.

[0066] In some embodiments, referring to Figure 4 , Figure 10 and Figure 11 as shown, at least one second hollow part 1221 is provided on the second support plate 122, and the second hollow part 1221 penetrates along the thickness direction of the second support plate 122. Specifically, the thickness direction of the second support plate 122 is Figure 11 the direction indicated by w. The structure and function of the second hollow part 1221 are similar to those of the first hollow part 1122, that is, the setting of the second hollow part 1221 can not only save the manufacturing cost of the transfer cart, but also increase the service life of the first bracket 111 and the mobile wheel set 2.

[0067] In some embodiments, referring to Figures 1 to 6 as shown, the mobile wheel set 2 includes a plurality of universal wheels.

[0068] Specifically, the mobile wheel sets 2 on the first support part 11 and the second support part 12 both include a plurality of universal wheels. This embodiment shows the case where the mobile wheel sets 2 on the first support part 11 and the second support part 12 both include four universal wheels. The setting of the universal wheels is beneficial to the transfer cart to turn during the process of transferring the battery 3, so that the transfer cart of this application can travel on a complex route, which is beneficial to the transfer of the battery 3.

[0069] As can be known from the above description: By providing the first support part 11 and the second support part 12 with adjustable spacing, the present application can solve the problem of transporting batteries of different sizes. The transport trolley of the present application can be made universal, that is, the transport trolley of the present application can be compatible with batteries 3 of different sizes. An operator can adjust the spacing between the first support part 11 and the second support part 12 and select different round holes, first long holes, and second long holes, so that batteries 3 of different sizes can be fixed between the first support part 11 and the second support part 12 of the transport trolley. This avoids the situation of increased costs and long development cycles caused by designing a dedicated transport trolley to deal with the problem of transporting batteries 3 of a new size.

[0070] That is to say, through simple structural settings, the transport trolley of the present application can not only achieve the generalization of the transport trolley, but also reduce the development cost and shorten the development cycle.
