Description

Technical Field

[0001] This application relates to the field of mechanical equipment, and in particular to a box-loading device. Background Technology

[0002] When packing items into boxes, packing devices are required. For example, there are devices that use vacuum suction equipment to pick up the items and move them for packing. Packing devices have wide applications in industrial production and transportation.

[0003] With the development of modern industry, the technical requirements for packaged goods are becoming increasingly stringent, which necessitates a wider variety of packaged goods handling devices to meet the needs of different application scenarios. Therefore, how to improve the structure of packaged goods handling devices to ensure the safe packaging of goods is an urgent problem to be solved. Summary of the Invention

[0004] This application provides a box-loading device that ensures that the boxed items can be safely packed.

[0005] In a first aspect, a box-loading device is provided for placing a box-loading component into a box body with the opening facing downwards. The box-loading device includes: a support portion extending along a first direction and located below the box-loading component to support it; a guide portion extending along a second direction for limiting the box-loading component in a third direction; and a pressurizing portion for limiting the box-loading component in the first direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other.

[0006] In this embodiment, the opening of the box faces downwards, and the box-inserting device places the box-inserting component into the box from below. The box-inserting device includes a supporting part, a guiding part, and a pressurizing part. The supporting part extends along a first direction and is located below the box-inserting component, serving to support it. The guiding part extends along a second direction and serves to limit the box-inserting component in a third direction. The pressurizing part serves to limit the box-inserting component in the first direction. In this technical solution, the supporting part, guiding part, and pressurizing part of the box-inserting device cooperate to place the box-inserting component into the box from below. Specifically, the supporting part supports the box-inserting component and provides support during its entry into the box. Since the supporting part extends along the first direction, its size can be adjusted according to the size of the box-inserting component, resulting in a larger contact area between the supporting part and the box-inserting component. This provides sufficient support, prevents the box-inserting component from falling during insertion, and ensures its safe placement into the box. Meanwhile, the guide section and the pressurizing section limit the entry component in the third direction and the first direction, respectively, to ensure that the gap between the entry component and the wall or beam of the box is small after the entry component enters the box, thereby improving the utilization rate of the internal space of the box.

[0007] In one possible implementation, the pressurizing part is provided with a groove for receiving the end of the bearing part.

[0008] During the process of placing the insert into the box, the bearing part moves towards the box, and the end of the bearing part is accommodated in the groove of the pressure part, so as to avoid the pressure part from hindering the movement of the bearing part when limiting the insert.

[0009] In one possible implementation, the box-loading device further includes a connecting portion extending along the third direction for connecting the carrying portion and the guide portion.

[0010] The connecting part connects the load-bearing part and the guide part, thereby enhancing the overall structure and structural strength of the box-entry device.

[0011] In one possible implementation, the box-loading device further includes a box-fixing part for mounting the box.

[0012] The box fixing part hangs the box to fix the box above the box insert, so that the box insert is put into the box from below.

[0013] In one possible implementation, the housing fixing part is provided with a through hole, and the guide part is inserted into the through hole.

[0014] The housing fixing part is provided with a through hole so that the guide part can be inserted into the through hole, thus preventing the housing fixing part from obstructing the movement of the guide part when the guide part is close to the housing.

[0015] In one possible implementation, the guide portion is provided with a first fixing structure, and the housing fixing portion is provided with a second fixing structure. The first fixing structure and the second fixing structure cooperate to fix the housing fixing portion and the guide portion together.

[0016] The first and second fixing structures work together to fix the box fixing part and the guide part together. The guide part is connected to the load-bearing part through the connecting part. In other words, the box fixing part, guide part, connecting part and load-bearing part are connected to form a whole to avoid the position of the box insert changing and to ensure that the box insert can be stably placed in the box.

[0017] In one possible implementation, the first fixing structure is a positioning groove on the guide portion, and the second fixing structure is a positioning member disposed on the upper surface of the housing fixing portion. The positioning member is inserted into the positioning groove to fix the housing fixing portion and the guide portion together.

[0018] The housing fixing part and the guide part are fixedly connected by the positioning part snapping into the positioning groove, which ensures the stability of the connection and facilitates operation.

[0019] In one possible implementation, the positioning element includes a rotatable positioning strip that rotates to engage with the positioning groove.

[0020] The positioning strip is rotatable. Before the insert is placed into the box, its position avoids the guide section, preventing it from obstructing the guide section's insertion through hole into the box's fixing part. Once the guide section is inserted into the box's fixing part, and the insert is placed into the box, the positioning strip is rotated to engage with the guide section's positioning groove, thus securing the guide section to the box's fixing part. The positioning strip's rotatable position differs before and after the insert is placed into the box, preventing obstruction of the guide section's movement while simultaneously securing it to the box's fixing part with the positioning groove, facilitating operation.

[0021] In one possible implementation, the box-loading device includes at least one pair of guides, each pair of guides including two guides opposite each other along the third direction.

[0022] A pair of guides includes two guides opposite each other along a third direction, which can further ensure that the insert is limited in the third direction. That is, the position of the insert is limited at both ends in the third direction by the guides, ensuring that the insert can be stably placed into the box.

[0023] In one possible implementation, the box-loading device includes two pairs of guides arranged along the first direction.

[0024] Two pairs of guides are provided in the first direction. On the one hand, they can better limit the placement of the box-in-the-box component in the third direction. On the other hand, the two pairs of guides are connected to the box-fixing part to ensure the overall stability of the box-in-the-box device. After the box-in-the-box component is placed in the box, the box-in-the-box device and the box need to be flipped. The overall connection of the box-in-the-box device is stable, which can ensure that the box-in-the-box component is stably placed in the box when flipped.

[0025] In one possible implementation, in the second direction, the distance L1 between the surface of the housing fixing part near the housing and the outer surface of the bottom wall of the housing is 2mm to 5mm.

[0026] Since the surface of the enclosure is not completely flat, if the enclosure fixing part is completely attached to the outer surface of the enclosure, it may cause the enclosure fixing part to tilt, which is not conducive to mounting the enclosure. In addition, the outer surface of the enclosure is sometimes coated with glue. If the enclosure fixing part is attached to the outer surface of the enclosure, it will scratch the glue and affect the quality of the glue application. However, the distance between the two should not be too large, otherwise the enclosure will easily shake when mounted on the enclosure fixing part. Therefore, the distance L1 between the surface of the enclosure fixing part near the enclosure and the outer surface of the bottom wall of the enclosure is set to 2mm~5mm.

[0027] In one possible implementation, in the third direction, the width L2 of the bearing portion is ≥10mm.

[0028] The width of the bearing part should not be too small. Otherwise, if the contact area between the box-in part and the bearing part is too small, the pressure generated will be too large, which will affect the bearing effect of the bearing part and cause the box-in part to bear too much pressure, which will damage the box-in part. Therefore, the width L2 of the bearing part should be set to be ≥10mm.

[0029] In one possible implementation, the housing component is a battery cell assembly, which includes multiple battery cells. The first surface of each battery cell faces the support portion, and an electrode terminal is provided on the first surface. The support portion is provided with a clearance groove, and the electrode terminal is accommodated in the clearance groove.

[0030] When the battery pack is a single battery cell assembly, the electrode terminals of the battery cells face downwards. This way, when the battery pack is placed in the housing and flipped over, the electrode terminals of the battery cells will face upwards, and the battery cells will be placed upright. At the same time, the support part is provided with a clearance groove. When the first side with the electrode terminals faces the support part, the electrode terminals are accommodated in the clearance groove, preventing the electrode terminals from being damaged by force.

[0031] The box-insertion device provided in this application embodiment is used to place a box-insertion component into a box body from below, with the box opening facing downwards. The box-insertion device includes a supporting part, a guiding part, and a pressurizing part. The supporting part extends along a first direction and is located below the box-insertion component, serving to support it. The guiding part extends along a second direction and serves to limit the box-insertion component in a third direction. The pressurizing part serves to limit the box-insertion component in the first direction. In the technical solution of this application, the supporting part, guiding part, and pressurizing part of the box-insertion device cooperate to place the box-insertion component into the box body from below. Specifically, the supporting part supports the box-insertion component and provides support during its entry into the box body. Since the supporting part extends along the first direction, its size can be adjusted according to the size of the box-insertion component, resulting in a larger contact area between the supporting part and the box-insertion component. This provides sufficient support for the box-insertion component, preventing it from falling during insertion and ensuring its safe placement into the box. Meanwhile, the guide section and the pressurizing section limit the entry component in the third direction and the first direction, respectively, to ensure that the gap between the entry component and the wall or beam of the box is small after the entry component enters the box, thereby improving the utilization rate of the internal space of the box.

[0046] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to illustrate the principles of this application by way of example, but should not be used to limit the scope of this application, that is, this application is not limited to the described embodiments.

Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. "Vertical" is not vertical in the strict sense, but within the allowable tolerance range. "Parallel" is not parallel in the strict sense, but within the allowable tolerance range.

[0048] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application. It should also be noted in the description of this application that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0050] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0051] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0052] In this application embodiment, the battery cell may include lithium-ion batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and this application embodiment is not limited to these. The battery cell may be cylindrical, flat, cuboid, or other shapes, etc., and this application embodiment is not limited to these. Battery cells are generally divided into three types according to their packaging method: cylindrical battery cells, cuboid / square battery cells, and pouch battery cells, and this application embodiment is not limited to these.

[0053] The battery mentioned in the embodiments of this application refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in this application may include a battery module or a battery pack. A battery generally includes a housing for encapsulating one or more battery cells. The housing prevents liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0054] In some battery packaging technologies, multiple individual battery cells can be integrated into a battery module or battery pack, which is then installed in a battery casing to form a battery pack. In other battery packaging technologies, multiple individual battery cells can be directly installed in a battery casing to form a battery pack; this type of battery packaging technology is also called cell-to-pack (CTP) packaging technology. In CTP packaging technology, by eliminating the intermediate state of the battery module, the weight of the battery pack can be reduced and the energy density of the battery can be increased. In other words, during the battery packaging process, multiple individual battery cells can be directly assembled into a battery, or they can first be assembled into a battery module or battery pack, and then the battery modules or battery packs can be assembled into a battery. The battery is installed in electrical equipment to provide power to the equipment.

[0055] The battery housing in this embodiment is used to house multiple battery modules, a busbar, and other battery components. In some embodiments, the housing may also include structures for securing the battery modules, such as beams. The shape of the housing can be determined based on the number of battery modules it houses. In some embodiments, the housing may be square and have six walls.

[0056] With the development of battery technology, the requirements for battery cell placement technology are becoming increasingly stringent. For example, it is necessary to ensure that the gap between the battery cell and the wall or beam of the box is small after the battery cell is placed in the box, so as to improve the utilization rate of the internal space of the box; another example is that when multiple battery cells are grouped together and placed in the box at the same time, due to the large weight of the battery cell group, it is necessary to ensure that the placement device can provide sufficient traction force during the placement process to ensure the safe placement of the battery cell group.

[0057] In some cases of box packing technology, box packing devices are used to hang the boxes and move them for packing. For example, vacuum suction equipment is used to pick up the boxes, or clamps are used to hold the boxes. This method of transporting boxes by hanging them with box packing devices has the risk of unstable suction or clamping, the boxes shaking or falling off the box packing device, and there are also certain limitations on the weight of the boxes.

[0058] In view of this, the inventor proposes a box-insertion device for placing a box-insertion component into the box from below. The device includes a support portion, a guide portion, and a pressurizing portion. The support portion extends along a first direction and is located below the box-insertion component, serving to support it. The guide portion extends along a second direction and serves to limit the box-insertion component in a third direction. The pressurizing portion also limits the box-insertion component in the first direction. In this application, the support portion, guide portion, and pressurizing portion of the box-insertion device cooperate to place the box-insertion component into the box from below. Specifically, the support portion supports the box-insertion component and provides support during its entry into the box. Since the support portion extends along the first direction, its size can be adjusted according to the size of the box-insertion component, ensuring a large contact area between the support portion and the component, providing sufficient support, preventing the component from falling during insertion, and ensuring safe placement. Meanwhile, the guide section and the pressurizing section limit the entry component in the third direction and the first direction, respectively, to ensure that the gap between the entry component and the wall or beam of the box is small after the entry component enters the box, thereby improving the utilization rate of the internal space of the box.

[0059] The technical solutions described in the embodiments of this application are applicable to various devices that use a boxing device for packaging, such as batteries, handicrafts, furniture products, toys, etc.

[0060] It should be understood that the technical solutions described in the embodiments of this application are not limited to the devices described above, but can also be applied to all devices that use a boxing device for packing.

[0061] Taking batteries as an example, using the above-mentioned box-loading device to assemble battery cells into the box can avoid the risk of battery cells falling out during the boxing process, and improve the safety of battery cell assembly into the box. In addition, since the box-loading device can limit the battery cell assembly, it can ensure that the battery cell assembly can be placed into the box against the wall or beam of the box, or there is a very small gap between the battery cell assembly and the wall or beam of the box, which improves the utilization rate of the internal space of the box and increases the energy density of the battery.

[0062] The technical solutions described in the embodiments of this application are applicable to various battery-powered devices, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, electric vehicles, ships, and spacecraft. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft.

[0063] It should be understood that the technical solutions described in the embodiments of this application are not limited to the devices described above, but can also be applied to all devices that use batteries. However, for the sake of brevity, the following embodiments are all illustrated using electric vehicles as examples.

[0064] For example, such as Figure 1 The diagram shown is a structural schematic of a vehicle 1 according to one embodiment of this application. Vehicle 1 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A motor, a controller 30, and a battery 10 can be installed inside vehicle 1. The controller 30 controls the battery 10 to supply power to the motor. For example, the battery 10 can be installed at the bottom, front, or rear of vehicle 1. The battery 10 can be used to power vehicle 1; for example, it can serve as the operating power source for the vehicle 1's electrical system, such as meeting the power requirements for starting, navigation, and operation. In another embodiment of this application, the battery 10 can not only serve as the operating power source for vehicle 1 but also as the driving power source, replacing or partially replacing gasoline or natural gas to provide driving power to vehicle 1.

[0065] To meet different power demands, battery 10 may include multiple individual battery cells. For example, Figure 2This is an exploded structural diagram of a battery 10 according to an embodiment of this application. The battery 10 may include multiple battery cells 20. The number of battery cells 20 can be set to any value according to different power requirements. Multiple battery cells 20 can be connected in series, parallel, or mixed connection to achieve a larger capacity or power. Since each battery 10 may include a large number of battery cells 20, for ease of installation, the battery cells 20 can be grouped, with each group of battery cells 20 forming a battery module. The number of battery cells 20 included in a battery module is not limited and can be set according to requirements. The battery may include multiple battery modules, which can be connected in series, parallel, or mixed connection.

[0066] Optionally, the battery 10 may also include other structures. For example, the battery 10 may further include a busbar component for realizing electrical connections between multiple battery cells 20, such as in parallel, series, or mixed connections. Specifically, the busbar component can realize electrical connections between battery cells 20 by connecting the electrode terminals of the battery cells 20. Further, the busbar component can be fixed to the electrode terminals of the battery cells 20 by welding. The electrical energy of the multiple battery cells 20 can be further led out through the housing via a conductive mechanism. Optionally, the conductive mechanism may also be part of the busbar component.

[0067] The battery 10 may also include a housing 11 (or cover), the housing 11 having a hollow interior structure, and multiple battery cells 20 are housed within the housing 11. Figure 2 As shown, the housing 11 may include two parts, referred to herein as the upper housing 111 and the lower housing 112, which are fastened together. The shapes of the upper housing 111 and the lower housing 112 may be determined according to the shape of the combination of multiple battery cells 20, and at least one component of the upper housing 111 and the lower housing 112 may have an opening. For example, the housing 11 may include only one of the upper housing 111 and the lower housing 112, which may be a hollow cuboid with an opening, while the other may be plate-shaped to cover the opening. For example, as... Figure 2 As shown, here the lower box 112 is a hollow cuboid with only one side being an open surface, and the upper box 111 is plate-shaped. The upper box 111 covers the opening of the lower box 112 to form a box 11 with a closed chamber, which can be used to accommodate multiple battery cells 20.

[0068] Optionally, the upper box 111 and lower box 112 included in the embodiment of this application may also have other shapes. For example, both the upper box 111 and the lower box 112 may be hollow cuboids with only one open side each. The openings of the upper box 111 and the lower box 112 are opposite to each other, and the upper box 111 and the lower box 112 are interlocked to form a box 11 with a closed cavity. Multiple battery cells 20 are connected in parallel, series, or mixed and placed in the box formed by the interlocking of the upper box 111 and the lower box 112.

[0069] like Figure 3 The diagram shown is a structural schematic of a battery cell 20 according to an embodiment of this application. The battery cell 20 includes one or more electrode assemblies 22, a housing 21, and an end cap 24. The housing 21 and the end cap 24 form a casing or battery box. The walls of the housing 21 and the end cap 24 are both referred to as the walls of the battery cell 20. For a cuboid battery cell 20, the walls of the housing 21 include a bottom wall and four side walls, which are connected to form a receiving space 23 for placing the electrode assemblies 22. The shape of the housing 21 depends on the shape of the combined one or more electrode assemblies 22. For example, the housing 21 can be a hollow cuboid, cube, or cylinder, and one side of the housing 21 has an opening so that one or more electrode assemblies 22 can be placed inside the housing 21. For example, when the housing 21 is a hollow cuboid or cube, one plane of the housing 21 is an open surface, that is, this plane does not have a wall, allowing communication between the inside and outside of the housing 21. When the housing 21 can be a hollow cylinder, the end face of the housing 21 is an open face, that is, the end face does not have a wall, allowing the inside and outside of the housing 21 to communicate. The end cap 24 covers the opening of the receiving space 23 and is connected to the housing 21 to form a closed cavity for placing the electrode assembly 22. The housing 21 is filled with an electrolyte, such as an electrolyte solution or a solid electrolyte.

[0070] The battery cell 20 may also include two electrode terminals 241, which may be disposed on the end cap 24. The end cap 24 is typically flat, and the two electrode terminals 241 are fixed to the flat surface of the end cap 24. The two electrode terminals 241 are respectively a positive electrode terminal 241a and a negative electrode terminal 241b. Each electrode terminal 241 is provided with a corresponding connecting member 25, or a current collector, which is located between the end cap 24 and the electrode assembly 22, and is used to electrically connect the electrode assembly 22 and the electrode terminal 241.

[0071] Figure 4 This illustration shows a scenario where a box-loading device according to an embodiment of this application places a box-loading component 40 into a box body 11. The opening of the box body 11 faces downward, and the box-loading device places the box-loading component 40 into the box body 11 from below.

[0072] Specifically, the box-loading device includes a supporting part 31, a guiding part 32, and a pressurizing part 33. The supporting part 31 extends along a first direction x and is located below the box-loading member 40 to support the box-loading member 40. The guiding part 32 extends along a second direction y and is used to limit the box-loading member 40 in a third direction z. The pressurizing part 33 is used to limit the box-loading member 40 in the first direction x, wherein the first direction x, the second direction y, and the third direction z are perpendicular to each other.

[0073] Below, in conjunction with the appendix Figure 4 This application describes in detail the process by which the box-loading device of this embodiment places the box-loading component 40 into the box body 11. First, the supporting part 31 carries the box-loading component 40 and moves it along a direction close to the box body 11. For example, Figure 4 The guide part 32 limits the insertion part 40 in the third direction z. Specifically, the guide part 32 is close to the outer surface of the first side wall 113 of the box body 11, so that the insertion part 40 can enter the box body 11 as close as possible to the inner surface of the first side wall 113 of the box body 11. The pressurizing part 33 limits the insertion part 40 in the first direction x. Specifically, the side of the pressurizing part 33 close to the insertion part 40 is aligned with the inner surface of the second side wall 114 of the box body 11 in the second direction y. When the bearing part 31 bears the load, the pressure part 33 limits the insertion part 40 in the first direction x. When the inlet component 40 enters the housing 11, the pressurizing part 33 is blocked by the second side wall 114 of the housing 11 and will not move with the movement of the inlet component 40. The inlet component 40 can then gradually move upward along the side of the pressurizing part 33 and enter the housing 11 along the inner surface of the second side wall 114 of the housing 11. The limiting of the inlet component 40 by the guide part 32 and the pressurizing part 33 makes the gap between the inlet component 40 and the wall of the housing 11 after entering the housing 11 very small, thereby improving the utilization rate of the internal space of the housing 11.

[0074] It should be understood that the description above of the box insert 40 "adhering" to the inner surface of the side wall of the box 11 does not mean that the box insert 40 and the box 11 are tightly adjacent without any gap, but rather that the gap between the box insert 40 and the box 11 is very small and within the allowable range of operational errors.

[0075] The materials of the bearing part 31, the guide part 32 and the pressurizing part 33 can be the same or different. For example, they can be steel, aluminum, alloy and composite materials, etc. This application does not limit them.

[0076] An embodiment of this application provides a box-loading device for placing a box-loading component 40 into a box body 11 from below, with the opening of the box body 11 facing downwards. The box-loading device includes a supporting portion 31, a guiding portion 32, and a pressurizing portion 33. The supporting portion 31 extends along a first direction x and is located below the box-loading component 40, serving to support the box-loading component 40. The guiding portion 32 extends along a second direction y and serves to limit the box-loading component 40 in a third direction z. The pressurizing portion 33 serves to limit the box-loading component 40 in the first direction x. In the technical solution of this application, the supporting portion 31, the guiding portion 32, and the pressurizing portion 33 of the box-loading device cooperate to place the box-loading component 40 into the box body 11 from below. Specifically, the supporting part 31 carries the insert 40 and provides support for the insert 40 as it enters the box 11. The supporting part 31 extends along the first direction x, meaning its size can be adjusted according to the dimensions of the insert 40, ensuring a large contact area between the supporting part 31 and the insert 40. This provides sufficient support and prevents the insert 40 from falling during insertion, ensuring its safe entry into the box. Simultaneously, the guiding part 32 and the pressurizing part 33 limit the insertion of the insert 40 in the third direction z and the first direction x, respectively, ensuring a small gap between the insert 40 and the wall or beam of the box 11 after entry, thus improving the utilization rate of the internal space of the box 11.

[0077] Optionally, in the embodiments of this application, such as Figure 4 As shown, the pressure part 33 is provided with a groove 331 for accommodating the end of the guide part 32.

[0078] Specifically, when the supporting part 31 carries the insert 40 into the box 11, the side of the pressurizing part 33 near the insert 40 is aligned with the inner surface of the second side wall 114 of the box 11 in the second direction y. The pressurizing part 33 is blocked by the second side wall 114 of the box 11 and will not move with the movement of the insert 40. The supporting part 31 carries the insert 40 and continues to move upward until the insert 40 is completely placed in the box 11. During this process, the position of the pressurizing part 33 remains unchanged and is still in close contact with the insert 40, limiting the insertion 40. At this time, the position of the pressurizing part 33 will block the upward movement of the supporting part 31. Therefore, the pressurizing part 33 is provided with a groove 331. The groove 331 matches the size of the end of the supporting part 31, so that the end of the supporting part 31 can be accommodated in the groove 331 and move up and down in the groove 331, thereby avoiding the pressurizing part 33 from blocking the movement of the supporting part 31.

[0079] In this embodiment of the application, during the process of placing the insert 40 into the box 11, the support part 31 moves toward the box 11, and the end of the support part 31 is accommodated in the groove 331 of the pressure part 33, so as to avoid the pressure part 33 from hindering the movement of the support part 31 when limiting the insert 40.

[0080] Optionally, in the embodiments of this application, such as Figure 4 As shown, the box-loading device also includes a connecting part 34, which extends along a third direction z and is used to connect the supporting part 31 and the guide part 32.

[0081] In this embodiment, the supporting part 31 and the guiding part 32 are connected by the connecting part 34, which enhances the overall structure of the box-entry device and strengthens the structure.

[0082] Optionally, the connecting part 34 and the supporting part 31 can be connected by means of adhesive bonding, welding, riveting, etc.; the connecting part 34 and the guide part 32 can also be connected by means of adhesive bonding, welding, riveting, etc., and this application does not limit this.

[0083] Optionally, the supporting part 31, the guide part 32, and the connecting part 34 can be integrally formed to save processing time and improve processing efficiency. The integrally formed structure has higher structural strength and improves the overall structural stability of the box-loading device. The integrally formed structure of the supporting part 31, the guide part 32, and the connecting part 34 can be achieved by stamping, die processing, etc., and this application does not limit this.

[0084] It should be understood that the supporting part 31, the guiding part 32 and the connecting part 34 can also be processed and assembled separately, and this application does not limit this.

[0085] Optionally, in the embodiments of this application, such as Figure 4 As shown, the box-in device also includes a box fixing part 35 for mounting the box 11.

[0086] There are several ways to mount the box 11 on the box fixing part 35. For example, the bottom wall of the box 11 is mounted on the box fixing part 35; or the two side walls of the box 11 that are arranged opposite to each other are mounted on the box fixing part 35. This application does not limit this.

[0087] In this embodiment, the box fixing part 35 hangs the box 11 to fix the box 11 above the box insert 40, so that the box insert 40 is inserted into the box 11 from below.

[0088] Optionally, in the embodiments of this application, such as Figure 4 As shown, the housing fixing part 35 is provided with a through hole 351, and the guide part 32 is inserted into the through hole 351.

[0089] In this embodiment, the housing fixing part 35 is provided with a through hole 351 so that the guide part 32 can be inserted into the through hole 351, thereby preventing the housing fixing part 35 from obstructing the movement of the guide part 32 when the guide part 32 is close to the housing 11.

[0090] Optionally, in this embodiment, the guide portion 32 is provided with a first fixing structure, and the housing fixing portion 35 is provided with a second fixing structure. The first fixing structure and the second fixing structure cooperate to fix the housing fixing portion 35 and the guide portion 32.

[0091] In this embodiment, the box fixing part 35 and the guide part 32 are fixedly connected by the cooperation of the first fixing structure and the second fixing structure. The guide part 32 is connected to the bearing part 31 through the connecting part 34. That is, the box fixing part 35, the guide part 32, the connecting part 34 and the bearing part 31 are connected to form a whole to avoid the change of position of the box insert 40 and ensure that the box insert 40 can be stably placed in the box 11.

[0092] Optionally, in the embodiments of this application, such as Figure 4 As shown, the first fixing structure is the positioning groove 321 on the guide part 32, and the second fixing structure is the positioning member 352 disposed on the upper surface of the housing fixing part 35. The positioning member 352 is inserted into the positioning groove 321 to fix the housing fixing part 35 and the guide part 32. By inserting the positioning member 352 into the positioning groove 321, the housing fixing part 35 and the guide part 32 are fixedly connected, ensuring the stability of the connection and facilitating operation.

[0093] Specifically, the positioning element 352 includes a rotatable positioning strip 3521. When the insert 40 is not fully inserted into the housing 11, the positioning strip 3521 is misaligned with the positioning groove 321; for example, the positioning strip 3521 is in a certain position. Figure 4 and Figure 5 Position a is shown; after the insert 40 is fully inserted into the housing 11, rotate the positioning strip 3521 so that the positioning strip 3521 is engaged in the positioning groove 321. For example, the positioning strip 3521 is in position a. Figure 5 Position b is shown.

[0094] In this embodiment, the positioning strip 3521 is rotatable. Before the insert 40 enters the box 11, the positioning strip 3521 is positioned to avoid the guide 32, preventing the positioning strip 3521 from obstructing the guide 32 from being inserted into the through hole of the box fixing part 35. After the guide 32 is inserted into the through hole of the box fixing part 35 and the insert 40 is placed into the box 11, the positioning strip 3521 is rotated to engage with the positioning groove 321 of the guide 32, thereby fixing the guide 32 to the box fixing part 35. The positioning strip 3521 is rotatable, and its position is different before and after the insert 40 is placed into the box 11. This not only avoids obstructing the movement of the guide 32 but also cooperates with the positioning groove 321 to fix the guide 32 to the box fixing part 35, facilitating operation.

[0095] It should be understood that the aforementioned first fixing structure, the positioning groove 321, and the second fixing structure, the positioning element 352, are merely exemplary embodiments of this application and do not constitute a limitation on this application. For example, the first fixing structure and the second fixing structure can be a matting connection of a mortise and tenon structure. Or, for example, the first fixing structure and the second fixing structure can be a matting connection of a nut and a bolt. This application does not limit this.

[0096] Optionally, in this embodiment of the application, the box-insertion device includes at least one pair of guide portions 32, each pair of guide portions 32 including two guide portions 32 opposite each other along the third direction z. This can further ensure that the box-insertion member 40 is limited in the third direction z, that is, both ends of the box-insertion member 40 in the third direction z are restricted in position by the guide portions 32, ensuring that the box-insertion member 40 can be stably placed into the box body 11.

[0097] Specifically, such as Figure 4 As shown, the box-loading device may include two pairs of guides 32, which are arranged along a first direction x.

[0098] In this embodiment, two pairs of guides 32 are provided in the first direction x. On the one hand, they can better limit the box entry part 40 in the third direction z. On the other hand, the two pairs of guides 32 are connected to the box body fixing part 35 to ensure the overall stability of the box entry device. After the box entry part 40 is placed in the box body 11, the box entry device and the box body 11 need to be flipped. The overall connection of the box entry device is stable, which can ensure that the box entry part 40 is stably placed in the box body 11 when flipped.

[0099] Optionally, when the box-loading device includes two pairs of guide portions 32, the positioning grooves 321 of the two guide portions 32 located on the same side of the two pairs of guide portions 32 are respectively disposed on the side of the two guide portions 32 that are close to each other, that is, as shown in the figure. Figure 4 The first positioning groove 3211 and the second positioning groove 3212 are shown. The first positioning groove 3211 and the second positioning groove 3212 correspond to the same positioning member 352. After the positioning strip 3521 of the positioning member 352 is rotated, part of it is inserted into the first positioning groove 3211 and the other part is inserted into the second positioning groove 3212.

[0100] Optionally, in this embodiment of the application, in the second direction y, the distance L1 between the surface of the housing fixing part 35 near the housing 11 and the outer surface of the bottom wall of the housing 11 is 2mm to 5mm, and L1 can be selected as 2mm, 3mm, 4mm or 5mm.

[0101] It should be understood that the surface of the housing fixing part 35 and the outer surface of the housing 11 are not completely flat planes. Therefore, the plane formed by the outer peripheral contour of the surface of the housing fixing part 35 near the housing 11 and the plane formed by the outer peripheral contour of the outer surface of the bottom wall of the housing 11 are used as the actual measurement planes. For example, Figure 6 L1 shown is the distance between the surface of the housing fixing part 35 near the housing 11 and the outer surface of the bottom wall of the housing 11.

[0102] Since the surface of the box 11 is not completely flat, if the box fixing part 35 is completely attached to the outer surface of the box 11, it may cause the box fixing part 35 to tilt, which is not conducive to the mounting of the box 11. In addition, the outer surface of the box 11 is sometimes coated with glue. If the box fixing part 35 is attached to the outer surface of the box 11, it will scratch the glue and affect the quality of the glue application. However, the distance between the two should not be too large, otherwise the box 11 will easily shake when mounted on the box fixing part 35. Therefore, the distance L1 between the surface of the box fixing part 35 near the box 11 and the outer surface of the bottom wall of the box 11 is set to 2mm~5mm.

[0103] Optionally, in the embodiments of this application, such as Figure 4 As shown, on the third direction z, the width L2 of the bearing part 31 is ≥10mm.

[0104] The width of the bearing part 31 should not be too small. Otherwise, if the contact area between the box insert 40 and the bearing part 31 is too small, the pressure generated will be too large, which will affect the bearing effect of the bearing part 31 and also cause the box insert 40 to bear too much pressure, which will damage the box insert 40. Therefore, the width L2 of the bearing part 31 is set to be ≥10mm.

[0105] Optionally, in this embodiment of the application, the housing 40 can be a battery cell pack, such as... Figure 5 and Figure 6 As shown, the battery cell pack includes a plurality of battery cells 20 arranged along the first direction x.

[0106] In this embodiment, the battery pack assembly is inserted into the housing 11, which avoids the risk of the battery cells 20 falling out during the packing process and improves the safety of the battery pack assembly. In addition, since the battery pack assembly can limit the battery cells, it ensures that the battery cells can be placed into the housing 11 against the wall or beam of the housing 11, or that there is a very small gap between the battery cells and the wall or beam of the housing 11, which improves the utilization rate of the internal space of the housing 11 and increases the energy density of the battery 10.

[0107] Specifically, such as Figure 7As shown, the first surface 211 of the battery cell 20 faces the support portion 31, and an electrode terminal 241 is provided on the first surface 211; the support portion 31 is provided with a clearance groove 311, and the electrode terminal 241 is accommodated in the clearance groove 311.

[0108] When the housing 40 contains a battery cell assembly, the electrode terminals 241 of the battery cell 20 face downwards. After the battery cell assembly is placed in the housing 11 and flipped over, the electrode terminals 241 of the battery cell 20 will face upwards, and the battery cell 20 will be placed upright. At the same time, the support part 31 is provided with a clearance groove 311. When the first surface 211 on which the electrode terminal 241 is provided faces the support part 31, the electrode terminal 241 is accommodated in the clearance groove 311, preventing the electrode terminal 241 from being damaged by force.

[0109] Optionally, such as Figure 7 As shown, the clearance groove 311 can be a plurality of discontinuous groove structures corresponding to the plurality of electrode terminals 241 respectively; such as Figure 8 As shown, the clearance groove 311 can also be a continuous groove structure extending along the first direction x.

[0110] Optionally, in the embodiments of this application, such as Figure 6 As shown, the pressurizing part 33 is opposite to the second surface 212 of the battery cell 20, and the second surface 212 is the surface of the battery cell 20 that is disposed opposite to each other along the first direction x.

[0111] The pressurizing part 33 not only limits the battery cell group in the first direction x, but also applies pressure to the battery cell group in the first direction x to compress and fix the size of the battery cell group in the first direction x to a predetermined size. This can compress the gap between multiple battery cells in the battery cell group, so that multiple battery cells are closely arranged and placed into the housing 11, thereby improving the utilization rate of the internal space of the housing 11 and increasing the energy density of the battery 10.

[0112] Optionally, in this embodiment, the second surface 212 is the surface with the largest surface area of ​​the battery cell 20, commonly referred to as the "large surface" of the battery cell 20. That is, multiple battery cells 20 in the battery cell group are arranged along the first direction x in a "large surface to large surface" configuration. The pressurizing part 33 faces the "large surface" of the battery cell 20. Thus, when the pressurizing part 33 pressurizes the battery cell group, it contacts the "large surface" of the battery cell 20, resulting in a larger contact area and thus lower pressure on the battery cell 20. Furthermore, the pressurizing part 33 faces the "large surface" of the battery cell 20, rather than the smaller side of the battery cell 20 where the water-cooling pipe (not shown in the figure) is located. This avoids the pressurizing part 33 contacting the water-cooling pipe when pressurizing the battery cell group, preventing damage to the water-cooling pipe.

[0113] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
