[0030] The specific embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0031] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0032] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the premise of each other's existence.

[0033] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0034] In order to solve the problem that the battery rack in the prior art cannot take both strength and weight into consideration, the present disclosure provides a battery installation cabinet. The battery installation cabinet includes a cabinet body 1 and at least two leg devices 2. The cabinet body 1 has accommodation spaces that are sequentially separated in the longitudinal direction, and the accommodation spaces are configured to at least place batteries;

[0035] At least two leg devices 2 are arranged in sequence and spaced apart in the transverse direction, and are configured to support the cabinet 1 and place it on a work surface;

[0036] The leg device 2 includes a hollow support beam 21 with a rectangular cross-section, the hollow support beam 21 has a mounting groove, and the bottom frame portion of the cabinet body 1 is embedded in the mounting groove; the leg device 2 also includes a first oblique reinforcing beam 22 arranged longitudinally obliquely, the upper end of the first oblique reinforcing beam 22 is fixedly connected to the cabinet body 1, and the lower end is fixedly connected to the hollow support beam 21.

[0037] Specifically, the cabinet body 1 of the battery installation cabinet is the main carrier for placing batteries, and multiple accommodating spaces are arranged inside it for placing batteries. The number and arrangement of batteries can be set accordingly according to specific needs of users.

[0038] A leg device 2 is provided at the bottom of the cabinet 1, and the leg device 2 is used to support the cabinet 1, and then support the cabinet 1 to be placed on the work surface. At the same time, the area supported by at least two leg devices 2, that is, the space formed between the leg devices 2 and the leg devices 2, can be used to place corresponding detection elements, so as to achieve reasonable use of space, and at the same time, the detection elements are protected by the leg devices 2.

[0039] like Figure 1 As shown, the hollow support beam 21 in the leg device 2 adopts a hollow structure, which effectively reduces the weight of the battery installation cabinet while supporting the cabinet body 1.

[0040] In order to ensure that the strength of the battery installation cabinet meets the design requirements, the battery installation cabinet is also provided with a first oblique reinforcing beam 22 whose upper end is fixedly connected to the cabinet body 1 and whose lower end is fixedly connected to the hollow support beam 21. The strength of the battery installation cabinet is improved by the first oblique reinforcing beam 22.

[0041] In addition, the hollow support beam 21 has an installation groove, and the bottom frame portion of the cabinet body 1 is embedded in the installation groove to achieve the connection between the cabinet body 1 and the hollow support beam 21. This setting method can effectively enhance the torsional strength of the connection between the cabinet body 1 and the hollow support beam 21.

[0042] It should be noted that the bottom frame of the cabinet 1 and the first oblique reinforcing beam 22 mentioned above can be set to a hollow structure, so as to reduce the weight of the battery installation cabinet.

[0043] In one embodiment of the present disclosure, a connecting reinforcement beam 23 is fixedly disposed between two adjacent hollow support beams 21 .

[0044] In actual applications, especially during the movement of the battery installation cabinet, objects in contact with the hollow support beam 21, such as the ground, will generate a force on the hollow support beam 21 of the battery installation cabinet, which may cause damage to the structure at the connection between the hollow support beam 21 and the cabinet body 1.

[0045] Therefore, the battery installation cabinet provided in the present invention improves the fatigue strength of the bottom of the battery installation cabinet by fixing a connecting reinforcement beam 23 between two adjacent hollow support beams 21, thereby strengthening the structure there to prevent it from being damaged.

[0046] In one embodiment of the present disclosure, the leg device 2 also includes a second oblique reinforcing beam 24 arranged longitudinally inclined, the upper end of the second oblique reinforcing beam 24 is fixedly connected to the connecting reinforcing beam 23, and the lower end is fixedly connected to the hollow supporting beam 21.

[0047] Specifically, see Figure 1 , between two adjacent hollow support beams 21, not only is there a connecting reinforcement beam 23, but also a second oblique reinforcement beam 24 is provided at the connecting end of the connecting reinforcement beam 23 and the hollow support beam 21. In actual scenarios, since the connecting reinforcement beam 23 and the hollow support beam 21 are often connected and fixed by welding, although this fixing method is convenient and reliable, there is often a stress concentration phenomenon at the welding point. Therefore, arranging the second oblique reinforcement beam 24 near the welding point can strengthen the local structure.

[0048] At the same time, the provision of the second oblique reinforcing beam 24 can also effectively solve the problem that the hollow support beam 21 flips inwards and causes structural damage during the left-right movement of the battery installation cabinet.

[0049] In one embodiment of the present disclosure, the length of the first oblique reinforcement beam 22 is greater than the length of the second oblique reinforcement beam 24 .

[0050] like Figure 1 As shown, the first oblique reinforcing beam 22 extends from the side of the hollow support beam 21 to the side of the cabinet 1, and is finally fixed to the bottom of the cabinet 1. The second oblique reinforcing beam 24 extends with both ends as close as possible to the welding point connecting the reinforcing beam 23 and the hollow support beam 21. Therefore, the length of the first oblique reinforcing beam 22 is greater than that of the second oblique reinforcing beam 24.

[0051] Such an arrangement not only improves the strength of the bottom of the battery installation cabinet, but also contributes to the stability of the structure.

[0052] In one embodiment of the present disclosure, a reinforcing plate is provided inside the hollow support beam 21 , the reinforcing plate extends from the middle of the hollow support beam 21 to the top surface of the inner wall, and the lower edge of the reinforcing plate has a trapezoidal notch.

[0053] Since the hollow support beam 21 in the leg device 2 adopts a hollow structure, it is beneficial to reduce the weight of the battery installation cabinet, but it also weakens the strength of the hollow support beam 21. Therefore, a reinforcing plate is arranged inside the hollow support beam 21, which can effectively improve the internal strength of the hollow support beam 21 and make it less likely to deform.

[0054] It should be noted that, in practical applications, a plurality of reinforcing plates may be placed inside the hollow support beam 21 to strengthen its structure. The specific configuration may be adjusted according to actual needs, and the disclosure will not be repeated here.

[0055] In one embodiment of the present disclosure, a contact bottom plate 25 is provided at the bottom of the hollow support beam 21 , and the contact bottom plate 25 is connected to the bottom of the hollow support beam 21 in a detachable manner.

[0056] In actual applications, the hollow support beam 21 needs to bear the weight of the entire battery installation cabinet and the batteries inside the battery installation cabinet. Even for some battery installation cabinets with special requirements, additional cooling systems and control components need to be installed inside. Therefore, the hollow support beam 21 bears a lot of weight.

[0057] The contact surface between the hollow support beam 21 and external objects often needs to bear a large load, and at the same time, it will cause a certain degree of wear and bumps during the moving and installation of the battery installation cabinet. What's more, during the installation of the battery installation cabinet, the direct contact surface between the hollow support beam 21 and the ground may be corroded, causing the strength of the hollow support beam 21 to decrease.

[0058] The battery installation cabinet provided by the present disclosure has a contact bottom plate 25 disposed on the bottom of the hollow support beam 21, which is detachably connected to the hollow support beam 21. This increases the thickness of the bottom of the hollow support beam 21, improves the strength of the hollow support beam 21, and protects the hollow support beam 21. At the same time, it is convenient to replace the damaged contact bottom plate 25 in time, which is conducive to reducing maintenance costs.

[0059] In one embodiment of the present disclosure, the cabinet 1 includes a plurality of rectangular horizontal frames 11 arranged in sequence and spaced apart along the longitudinal direction, and supporting columns 12 for supporting and fixing the plurality of rectangular horizontal frames 11, a receiving space is formed between two adjacent rectangular horizontal frames 11 in the longitudinal direction, and a plurality of load-bearing beams 13 are arranged in sequence and spaced apart between two opposite sides of the rectangular horizontal frame 11, and the load-bearing beams 13 are constructed to carry batteries; and the front side frame and the rear side frame of the bottom rectangular horizontal frame 11 are partially embedded in the installation groove of the hollow support beam 21.

[0060] Specific as Figure 1 As shown, a plurality of rectangular horizontal frames 11 are arranged inside the battery installation cabinet, and the size of the rectangular horizontal frames 11 is smaller than the size of the battery to ensure that the battery can be placed on the rectangular horizontal frames 11. At the same time, the supporting columns 12 and the load-bearing beams 13 connect the rectangular horizontal frames 11 and carry the rectangular horizontal frames 11 and the batteries.

[0061] The battery installation cabinet places batteries via a rectangular horizontal frame 11, which can effectively save installation space and facilitate the insertion of lines between batteries. At the same time, these spaces can also be used to install the battery cooling system, thereby improving the space utilization of the battery installation cabinet.

[0062] Of course, in another embodiment of the present disclosure, the cabinet 1 includes a plurality of rectangular horizontal frames 11 arranged in sequence along the longitudinal direction, and supporting columns 12 for supporting and fixing the plurality of rectangular horizontal frames 11. An accommodating space is formed between two adjacent rectangular horizontal frames 11 in the longitudinal direction. A carrying plate is arranged in the rectangular horizontal frame 11, and the carrying plate is constructed to carry batteries. Moreover, the front frame and the rear frame of the bottom rectangular horizontal frame 11 are partially embedded in the installation groove of the hollow support beam 21.

[0063] That is, in this embodiment, the battery installation cabinet adopts a rectangular horizontal frame 11 combined with a load-bearing plate to realize the support and fixation of the battery, thereby increasing the contact area between the battery and the load-bearing plate and improving the installation stability of the battery installation cabinet.

[0064] In one embodiment of the present disclosure, the leg device 2 further includes a third oblique reinforcing beam 26 , the upper end of the third oblique reinforcing beam 26 is fixedly connected to the supporting column 12 , and the lower end is fixedly connected to the hollow supporting beam 21 .

[0065] Specifically, the length of the hollow support beam 21 is greater than the width of the cabinet 1, so both ends of the hollow support beam 21 will exceed the outer contour of the cabinet 1. Considering that the battery installation cabinet will shake back and forth during movement, in order to ensure the installation stability of the leg device 2 and the cabinet 1, a third oblique reinforcement beam 26 is provided to stabilize the leg device 2 and the cabinet 1.

[0066] In one embodiment of the present disclosure, the cabinet 1 further comprises a cover 14 , which is detachably arranged on the outer surface of the cabinet 1 , wherein a hanging structure is arranged on the outer side of the cover 14 at the top of the cabinet 1 .

[0067] In practical applications, in order to protect the batteries inside the battery cabinet, a cover 14 needs to be provided on the surface of the battery cabinet to prevent excessive dust and moisture in the environment from entering the battery cabinet and affecting the operation of the battery system.

[0068] At the same time, a hoisting structure is provided on the outer side of the cover 14 at the top of the cabinet body 1, so that when the battery installation cabinet is installed, the installation of the battery installation cabinet is completed by cooperating with the hoisting structure through the hoisting device.

[0069] In addition, the cover 14 on the side of the cabinet 1 is also provided with a maintenance window to repair the components inside the battery installation cabinet. The cover 14 on the rear side of the cabinet 1 is provided with heat dissipation holes to facilitate timely discharge of heat generated by battery operation to prevent battery failure due to overheating.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the marketplace, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
