Description

A modular battery box for a pure electric loader Technical Field

[0001] This application relates to the technical field of battery boxes, and in particular to an assembled battery box for a pure electric loader. Background Technology

[0002] With environmental issues becoming increasingly prominent, green power is gradually becoming the mainstream, and pure electric loaders have become the main development direction for loaders. As the core of pure electric loaders, batteries are usually installed in the rear area of ​​the loader via a battery box.

[0003] The varying range and total voltage requirements of pure electric loaders often lead to inconsistencies in the number of batteries required. The greater the range or the higher the total voltage requirement, the more batteries are needed. When the number of batteries is small, such as five or fewer, the battery box is typically installed at a higher height to fully accommodate all the batteries and reduce its footprint. Conversely, when the number of batteries is large, the battery box's mounting area is typically increased to fully accommodate all the batteries and lower its center of gravity.

[0004] The existing battery boxes of pure electric loaders cannot simultaneously adjust the battery installation height and installation area, making it difficult to reasonably configure the battery installation height and installation area according to the actual needs of pure electric loaders. As a result, the battery boxes are prone to defects such as unstable center of gravity or large space occupation. Summary of the Invention

[0005] In order to enable the battery box to reasonably configure the battery installation height and installation area according to the actual needs of the pure electric loader, so as to avoid the defects of unstable center of gravity or large space occupation of the battery box, this application provides a modular battery box for pure electric loaders.

[0006] This application provides a modular battery box for a pure electric loader, which adopts the following technical solution:

[0007] A modular battery box for a pure electric loader includes support columns, box panels, and connecting columns. The support columns include at least two pillars arranged along the axial direction, which are detachably connected to adjacent pillars. The box panels are provided in three or more sets, with each set containing two or more boxes. All boxes in each set are slidably mounted on the support columns. Adjacent sets of boxes correspond one-to-one and are positioned facing each other. The connecting columns are provided in multiple sets, which are positioned one-to-one between all two facing boxes. Each set of connecting columns contains at least three connecting columns, and the two ends of each connecting column are detachably connected to the corresponding two boxes.

[0008] Optionally, the top of the support column is connected to a splicing block, and the bottom end is provided with a splicing groove, and the splicing block of the lower support column is threadedly connected to the splicing groove of the upper support column.

[0009] Optionally, a locking nut is threaded onto the topmost splice block.

[0010] Optionally, at least one slider is connected to the box plate. The slider is slidably disposed in a groove opened along the axial direction on the side wall of the support column, and the groove passes through the top of the support column.

[0011] Optionally, both ends of the connecting column are provided with connecting grooves, and connecting heads are threaded into the connecting grooves and connected to the box plate.

[0012] Optionally, the sidewall of the connecting column is provided with multiple anti-slip protrusions along the circumferential direction.

[0013] Optionally, a connecting plate is provided between each pair of adjacent box panels in each group. The connecting plate has a reinforcing groove on both sides near the two box panels. A reinforcing strip is connected to the side of each pair of adjacent box panels that is close to each other. The reinforcing strip is slidably inserted into the reinforcing groove.

Detailed Implementation

[0026] The present application will be further described in detail below with reference to Figures 1-5.

[0027] This application discloses a modular battery box for a pure electric loader. Referring to Figures 1 and 2, a modular battery box for a pure electric loader includes a support column 1, a box plate 2, and a connecting column 3.

[0028] The support column 1 includes five pillars 11 arranged along the axial direction, and adjacent pillars 11 are detachably connected. In actual use, the number of pillars 11 is selected according to the number of batteries to adjust the battery installation height.

[0029] The housing 2 is rectangular and consists of six groups, with four housing 2 in each group. All housing 2 in each group are slidably mounted on the support column 1 along its axis and are evenly distributed around the axis of the support column 1. Adjacent groups of housing 2 correspond one-to-one and are positioned directly opposite each other, forming the battery mounting space between two directly opposite housing 2. In actual use, the number of housing 2 in each group is selected according to the number of batteries to adjust the battery mounting area.

[0030] There are twenty sets of connecting posts 3, which are arranged one-to-one between all the two box panels 2 that are facing each other. Each set of connecting posts 3 consists of four posts. The four connecting posts 3 are located at the four top corners of the box panel 2. The two ends of the connecting posts 3 are detachably connected to the two corresponding box panels 2. The connecting posts 3 enhance the load-bearing capacity of the box panels 2.

[0031] In use, the number of support pillars 11 and each set of box panels 2 is determined according to the number of batteries. Then, the support pillars 11 and box panels 2 are assembled, and the box panels 2 facing each other are connected by connecting pillars 3 to ensure that the strength of the box panels 2 is sufficient to support the batteries. This allows the battery installation height and installation area of ​​the battery box to be adjusted based on the number of batteries, so that the battery box can be reasonably configured with the battery installation height and installation area according to the actual needs of the pure electric loader, so as to avoid defects such as unstable center of gravity or large space occupation of the battery box.

[0032] Specifically, referring to Figure 2, the top of the support column 11 is fixedly connected to a splicing block 111, and the bottom is provided with a splicing groove 112. The splicing block 111 of the lower support column 11 is threaded into the splicing groove 112 of the upper support column 11. Two adjacent support columns 11 can be detachably connected through the splicing block 111 and the splicing groove 112, so that after the number of support columns 11 is determined, the support columns 11 can be quickly connected to form a support column 1.

[0033] Referring to Figures 1 and 2, in order to prevent the box panel 2 from slipping off the support column 1, a locking nut 12 is threaded onto the topmost splicing block 111. The locking nut 12 is used to apply a resisting force to the topmost box panel 2. The threaded connection of the locking nut 12 to the topmost splicing block 111 can prevent the box panel 2 from slipping off the support column 1. At the same time, the locking nut 12 applies a resisting force to the topmost box panel 2, which can fix the position of the box panel 2 on the support column 1.

[0034] Specifically, referring to Figure 3, two sliders 21 are fixedly connected to the box plate 2. The sliders 21 are slidably disposed in the grooves 13 opened along the axial direction on the side wall of the support column 1. The grooves 13 pass through the top of the support column 1.

[0035] The slider 21 and the groove 13 form a sliding connection structure between the box plate 2 and the support column 1. Since the groove 13 passes through the top of the support column 1, the slider 21 on the box plate 2 can slide from the top of the groove 13 into the groove 13. The slider 21 on the bottom box plate 2 can abut against the groove wall at the bottom of the groove 13 to support the other layers of box plates 2.

[0036] Specifically, referring to Figure 4, both ends of the connecting post 3 are provided with connecting grooves 31, and connecting heads 22 are threaded into the connecting grooves 31. The connecting heads 22 are fixed to the box plate 2. When the connecting heads 22 are connected in the connecting grooves 31, the ends of the connecting post 3 can be pressed against the box plate 2.

[0037] Tighten the connecting post 3 so that the connector 22 on the box plate 2 can be threaded into the connecting groove 31. The connecting post 3 can detachably connect the two box plates 2 facing each other through the connector 22, and the connecting post 3 can play an anti-loosening role by the clamping force of its own end against the box plate 2.

[0038] Referring to Figure 5, in order to prevent slippage when the connecting post 3 is turned, multiple anti-slip ridges 32 are fixedly connected to the side wall of the connecting post 3 along the circumferential direction. The anti-slip ridges 32 improve the anti-slip performance of the surface of the connecting post 3, making it less likely for the connecting post 3 to slip when rotating.

[0039] Referring to Figure 5, in order to enhance the overall support strength of each group of box panels 2, a connecting plate 4 is provided between each pair of adjacent box panels 2. The connecting plate 4 has a reinforcing groove 41 on both sides near the two box panels 2. The reinforcing groove 41 penetrates the two end faces of the connecting plate 4. A reinforcing strip 23 is fixedly connected to the side of each pair of adjacent box panels 2 that is close to each other. The reinforcing strip 23 is slidably inserted into the reinforcing groove 41.

[0040] By connecting the two reinforcing strips 23 with the connecting plate 4, the two adjacent box panels 2 in each group are fixed in a fixed state, so that all the box panels 2 in each group can be connected to form a whole, which enhances the overall support strength of each group of box panels 2.

[0041] Referring to Figure 1, in order to reduce the dust accumulation on the battery, at least one dustproof mesh 5 is bolted between each pair of oppositely positioned boxes 2. The dustproof mesh 5 can prevent dust from escaping between the two oppositely positioned boxes 2, thereby reducing the dust accumulation on the battery.

[0042] Referring to Figure 2, in order to enhance the support stability of the support column 1 on the box plate 2, multiple sets of support ribs 6 are provided at the bottom of the support column 1. Each set of support ribs 6 corresponds to one of the boxes plate 2 closest to the bottom of the support column 1. Each set of support ribs 6 consists of two ribs. The support ribs 6 are connected to the support column 1 and are used to abut against the bottom surface of the box plate 2.

[0043] The support rib 6 forms a support surface at the bottom end of the support column 1. The support surface formed by the support rib 6 can provide support for all the box panels 2, thereby enhancing the support stability of the support column 1 for the box panels 2.

[0044] Furthermore, referring to Figure 2, the support rib 6 is hinged to the support column 1, and the swing angle of the support rib 6 is 90 degrees. The support rib 6 can swing from the position that is attached to the support column 1 to the position that is perpendicular to the support column 1.

[0045] When the area corresponding to the support rib 6 is not fitted with the box panel 2, the support rib 6 can be swung to a position that fits against the support column 1, and then the support rib 6 can be fixed to the support column 1 with wire or cable ties, so that the support rib 6, which does not need to provide support force, can be retracted, thus reducing the space occupied by the support rib 6 when reducing the battery installation area; when the area corresponding to the support rib 6 is fitted with the box panel 2, the support rib 6 can be swung to a position perpendicular to the support column 1, so that the support rib 6 can provide support force to the box panel 2 with the side wall of the support column 1 as the support point.

[0046] The implementation principle of the modular battery box for a pure electric loader according to this application embodiment is as follows: In use, the number of support columns 11 and the number of each set of box panels 2 are determined according to the number of batteries. The support columns 11 are connected to form support columns 1 through splicing blocks 111 and splicing grooves 112. The support ribs 6 at the bottom of the support column 1 are swung to a state perpendicular to the support column 1. Each set of box panels 2 is slidably connected to the support column 1 through sliders 21, and adjacent box panels 2 are fixed through connecting plates 4. The support ribs 6 provide support force to the box panels 2. The locking nut 12 is connected to the topmost splicing block 111 to prevent the box panels 2 from slipping off the support column 1. Thus, the battery box can reasonably configure the battery installation height and installation area according to the actual needs of the pure electric loader, so as to avoid defects such as unstable center of gravity or large space occupation of the battery box.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
