DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0042] In view of the problem in the related art that two parallel batteries occupy a large installation space when placed horizontally, the utility model provides a battery fixing device, a battery assembly and an operating machine.

[0043] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0044] According to an embodiment of the utility model, in a first aspect, as Figures 1 to 4 As shown, a battery fixing device is provided, which is suitable for fixing a first battery 7 and a second battery 8 spaced apart in an upper and lower direction, and mainly comprises: a chassis 1, a plurality of support rods 2, a tray 3 and a limiting assembly 4.

[0045] Specifically, the chassis 1 is suitable for placing the first battery 7; one end of a plurality of support rods 2 is installed on the chassis 1, and is suitable for surrounding the first battery 7; the tray 3 is installed on the other end of the support rod 2 and leaves a gap with the upper surface 701 of the first battery, and the tray 3 is suitable for placing the second battery 8; the limiting assembly 4 is installed on the tray 3 and is suitable for surrounding the second battery 8 and the upper surface 801 of the second battery.

[0046] This embodiment uses a plurality of support rods 2 and a tray 3 to place the second battery 8 above the first battery 7, thereby effectively utilizing the upper space of the first battery 7 and reducing the occupation of the horizontal space of the operating machinery. In addition, a gap is left between the tray 3 and the upper surface 701 of the first battery, which can prevent the first battery 7 located below from bearing the entire weight of the second battery 8, thereby improving the safety of the battery. Furthermore, the embodiment of the utility model can improve the stability of the second battery 8 on the tray 3 by providing a limit assembly 4 on the tray 3, thereby preventing the vibration generated by the operating machinery in the working state from causing the position of the second battery 8 to shift.

[0047] It can be understood that the support rod 2 in this embodiment can not only be used to support the tray 3 and the second battery 8 arranged on the tray 3, but also can form a limiting structure for the first battery 7. In addition, the support rod 2 in this embodiment can be arranged at the four corners of the first battery 7, or can be arranged on the opposite sides of the first battery 7, as long as the second battery 8 can be stably supported. Similarly, the number of support rods 2 arranged on the side of the first battery 7 can be but is not limited to two, three or four. The following is a description of the arrangement of the support rods 2 on the side of the first battery 7 with reference to specific examples:

[0048] In one example, two support rods 2 are arranged around the first storage battery 7, and the two support rods 2 are arranged oppositely on both sides of the first storage battery 7. Preferably, the two support rods 2 are arranged along the length direction of the tray 3.

[0049] In another example, three support rods 2 are arranged around the first battery 7 , wherein two support rods 2 are located on the same side of the first battery 7 , and the remaining support rod 2 is arranged on the other side of the first battery 7 .

[0050] In another example, four support rods 2 are arranged around the first battery 7 , and the four support rods 2 are arranged on both sides of the first battery 7 in pairs, or the four support rods 2 are arranged at four corners of the first battery 7 respectively.

[0051] According to an embodiment of the utility model, the support rod 2 includes a rod body 201 and a positioning protrusion 202 located at one end of the rod body 201, and a step surface 203 is formed at the connection between the positioning protrusion 202 and the rod body 201. The positioning protrusion 202 is inserted into the connection hole of the tray 3 and is fixedly connected to the tray 3 through a connecting member. The step surface 203 is located above the first storage battery 7 and supports the tray 3. By providing the positioning protrusion 202 at one end of the support rod 2 and providing a connection hole matched with the positioning protrusion 202 on the tray 3, the tray 3 can be accurately positioned with the support rod 2, simplifying the installation process. Furthermore, by providing the connection between the positioning protrusion 202 and the rod body 201 as a step surface 203, the contact area between the tray 3 and the support rod 2 can be increased, ensuring that the support rod 2 can provide sufficient bearing capacity for the tray 3.

[0052] In a specific embodiment, the positioning protrusion 202 and the rod body 201 are both cylindrical, and the positioning protrusion 202 and the rod body 201 are coaxially arranged, with a simple structure, convenient manufacturing and use. The diameter of the positioning protrusion 202 is smaller than the diameter of the rod body 201, and a circular step surface 203 can be formed between the positioning protrusion 202 and the rod body 201 to accurately position the tray 3 at a desired height.

[0053] In some other embodiments, the positioning protrusion 202 and the rod body 201 can also be configured as other conventional structures such as square columns, triangular columns, etc. as required. For example, the positioning protrusion 202 is configured as a cylindrical shape, and the rod body 201 is configured as a square column. The diameter of the positioning protrusion 202 is smaller than the width of the rod body 201, and a step surface 203 is formed between the positioning protrusion 202 and the rod body 201.

[0054] Furthermore, in one embodiment, the positioning protrusion 202 is provided with an external thread, the connecting member is a nut, and the positioning protrusion 202 passes through the connecting hole and is tightened on the pallet 3 through the nut. Through the cooperation between the nut and the external thread on the positioning protrusion 202, the pallet 3 can be firmly fixed on the step surface 203 of the support rod 2, preventing the vibration generated by the operating machine in the working state from causing the pallet 3 to fall off the support rod 2. In addition, by utilizing the characteristics of the threaded connection, the operation steps of installation and disassembly can be simplified, and the maintenance cost can be reduced.

[0055] It is understandable that, in order to improve the portability of installation and removal between the support rod 2 and the chassis 1, an external thread may be provided at one end of the support rod 2 connected to the chassis 1, and an internal thread hole adapted thereto may be provided on the chassis 1. Further, in order to improve the accuracy of installation and positioning, the size of one end of the support rod 2 connected to the chassis 1 may be smaller than the size of the rod body 201, thereby forming a step surface 203 at the connection between the two.

[0056] According to an embodiment of the utility model, the limiting assembly 4 includes a limiting pressure plate 401 and a plurality of limiting rods 402, one end of the plurality of limiting rods 402 is connected to the tray 3, and the other end is connected to the limiting pressure plate 401, the limiting pressure plate 401 is suitable for being pressed on the upper surface 801 of the second battery, and the limiting pressure plate 401, the plurality of limiting rods 402 and the tray 3 form a limiting space for the second battery 8. By arranging the second battery 8 in the limiting space of the second battery 8 formed by the limiting pressure plate 401, the plurality of limiting rods 402 and the tray 3, the second battery 8 can be stably fixed above the first battery 7 to prevent the second battery 8 from colliding with other components.

[0057] It should be noted that the shape of the limiting pressure plate 401 in the embodiment of the present invention can be rectangular, elliptical or triangular. As long as it can cooperate with the limiting rod 402 to firmly limit the second battery 8 between the limiting pressure plate 401 and the tray 3, the present invention does not make any specific restrictions on this. In addition, in order to improve the structural strength and service life of the limiting pressure plate 401, a flange structure can be provided on the peripheral side of the upper surface of the limiting pressure plate 401.

[0058] According to an embodiment of the utility model, a limiting boss 5 corresponding to a plurality of limiting rods 402 is provided on the tray 3, a threaded hole is provided in the limiting boss 5, and the limiting rod 402 is screwed with the threaded hole. By providing the limiting boss 5 on the tray 3, a placement space for the second battery 8 can be formed on the tray 3, which is conducive to the installation and positioning of the second battery 8 and simplifies the installation process. Furthermore, by providing an internal threaded hole on the limiting boss 5, a detachable connection between the limiting rod 402 and the tray 3 can be achieved, thereby improving the efficiency of installation and disassembly and reducing subsequent maintenance costs. In addition, by providing the limiting boss 5 on the tray 3 in advance, the installation and positioning of the second battery 8 can also be facilitated, the installation process is simplified, and the installation efficiency is improved.

[0059] In a specific embodiment, the limiting rod 402 is configured as a screw rod, so that not only can the limiting rod 402 be detachably connected to the limiting boss 5, but also the limiting rod 402 and the limiting pressure plate 401 can be detachably connected, thereby improving the efficiency of installation and removal and reducing subsequent maintenance costs. Since the detachable connection between the limiting rod 402 and the limiting pressure plate 401 requires the use of a nut, the cooperation between the nut and the thread on the limiting rod 402 can facilitate the staff to adjust the downward pressure generated by the limiting pressure plate 401 on the second battery 8.

[0060] According to an embodiment of the utility model, the limiting assembly 4 further includes a pair of limiting baffles 403 mounted on the tray 3, the pair of limiting baffles 403 are suitable for being arranged on opposite sides of the second storage battery 8 along the first direction, and the plurality of limiting rods 402 are suitable for being arranged on opposite sides of the second storage battery 8 along the second direction, and the first direction is arranged perpendicular to the second direction. By arranging the limiting baffles 403 in the first direction and the limiting rods 402 in the second direction, the second storage battery 8 can be prevented from being displaced in the first direction and the second direction, so that the second storage battery 8 can be securely fixed on the tray 3.

[0061] It should be noted that the first direction in this embodiment may be the width direction of the tray 3, and the second direction may be the length direction of the tray 3. In addition, the position limiting baffles 403 in this embodiment may be relatively arranged on both sides of the second battery 8, or may be staggeredly arranged on both sides of the second battery 8, as long as the position limiting of the second battery 8 can be achieved. Furthermore, the number of the position limiting baffles 403 in this embodiment may also be two pairs or three pairs.

[0062] According to an embodiment of the utility model, the tray 3 includes a tray body 301 and flanges 302 arranged on opposite sides of the tray body 301, the tray body 301 is suitable for connecting with the support rod 2, and an escape space 303 is left between the lower surface of the flange 302 and the upper surface 701 of the first battery. By connecting the tray body 301 with the support rod 2, the weight of the tray 3 and the second battery 8 can be placed on the support rod 2, preventing the first battery 7 from being compressed and deformed, thereby improving the safety of the battery. In addition, by arranging the flanges 302 on both sides of the tray body 301, on the one hand, the contact area between the second battery 8 and the tray 3 can be increased, and the stability between the second battery 8 and the tray 3 can be improved; on the other hand, by arranging the flanges 302, the poles on the first battery 7 can be prevented from contacting the tray 3.

[0063] It should be noted that the material of the tray 3 in this embodiment can be metal or hard plastic. In a specific embodiment, the tray 3 is made of hard plastic. Compared with using metal materials to prepare the tray 3, the preparation cost of the tray 3 made of hard plastic is lower, and it is not easy to cause the positive and negative poles on the first battery 7 to short-circuit, thereby improving safety.

[0064] According to an embodiment of the utility model, the gap is filled with a rubber pad 6, which can make the rubber pad 6 an intermediate load between the tray 3 and the first battery 7, that is, the tray 3 and the first battery 7 are tightly connected, thereby completing the position limitation of the first battery 7. In addition, since the rubber pad 6 is a deformable elastic material, it can play a role in vibration reduction and energy absorption between the tray 3 and the first battery 7.

[0065] Furthermore, in order to ensure that the rubber pad 6 can fill the entire gap, the size of the rubber pad 6 may be slightly larger than the size of the gap.
