Description

Technical Field

[0001] The utility model relates to the technical field of operating machinery, in particular to a battery fixing device and an operating machinery. Background Art

[0002] Batteries are important and essential components of electric working machinery and require a reliable and stable fixing method. The current battery fixing device of electric working machinery (such as excavators) is a typical battery fixing method, which includes a "J"-shaped pressure plate and a fixed pad. The pressure plate is a bent part that is bent four times continuously. When fixing, the main body of the pressure plate is pressed on the upper end surface of the battery and extends all the way to the bottom of the battery. The fixing parts on both sides of the main body of the pressure plate are located on the battery. The fixing bolts pass through the fixing part of the pressure plate, the battery and the mounting holes on the fixed pad in turn for threaded tightening. However, the existing battery fixing device has at least the following disadvantages:

[0003] 1) Since the shape and size of the pressure plate are adapted to the shape and size of the battery, only one type of battery can be fixed, and the scope of application is narrow.

[0004] 2) The "J"-shaped pressure plate and fixing bolts used to secure the battery only limit the battery's freedom of movement in the vertical, front-back, or left-right directions, but not in both the left-right and front-back directions. Therefore, existing battery securing devices lack sufficient positioning and provide a less secure fixation. Utility Model Content

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0038] The battery fixing device of the related art has at least the following disadvantages:

[0039] 1) Using a "J"-shaped pressing plate for fixing, since the shape and size of the pressing plate are adapted to the shape and size of the battery, it can only fix one type of battery and has a narrow scope of application.

[0040] 2) The "J"-shaped pressure plate and fixing bolts used to secure the battery only limit the battery's freedom of movement in the vertical, front-back, or left-right directions, but not in the left-right or front-back directions. Therefore, existing battery securing devices lack sufficient positioning and provide insecure fixation.

[0041] 3) The fixing bolts for fixing the pressure plate are located on both sides of the battery. A certain amount of space needs to be reserved on both sides of the battery for the installation of the fixing bolts, thus wasting the space on both sides of the battery. The structure is not compact enough and cannot be used to fix the battery in a limited space.

[0042] 4) The fixing bolts for fixing the pressure plate are located at the bottom of the battery, making disassembly and maintenance inconvenient.

[0043] 5) It does not have insulation and shock absorption protection functions, and lacks protection for the battery.

[0044] In order to solve the above technical problems, the following Figures 1 to 2 , describing the embodiments of the present utility model.

[0045] According to an embodiment of the present invention, on the one hand, a battery fixing device is provided, comprising:

[0046] The box body 10 is used to carry and accommodate the battery 50. The box body 10 includes a bottom plate 11 and side plates 12 arranged around the bottom plate 11 and opposite to each other.

[0047] The first adjustment and limiting mechanism 20 includes a first adjustment and limiting assembly and a positioning plate 22. The positioning plate 22 is fixedly connected to at least one of the side plates 12 and is located above the battery 50. The first adjustment and limiting assembly is disposed through the positioning plate 22 to adjustably press the battery 50 in the Z-axis direction and secure the battery 50 to the bottom plate 11.

[0048] The second adjustment and limiting mechanism 30 is used to adjustably press the battery 50 in the X-axis direction and make the battery 50 tightly pressed against the side plate 12 in the direction in which it is located;

[0049] The third adjustment and limiting mechanism 40 is used to adjustably press the battery 50 in the Y-axis direction and make the battery 50 tightly pressed against the side plate 12 in the direction in which it is located.

[0050] In this embodiment, the battery 50 is limited in three directions, namely, the X-axis direction, the Y-axis direction, and the Z-axis direction, by means of the first adjustment limit mechanism 20, the second adjustment limit mechanism 30, and the third adjustment limit mechanism 40. The limitation is sufficient so that the battery 50 is tightly combined with the box body 10, thereby ensuring that the battery 50 is firmly fixed.

[0051] Since the first adjustment and limiting mechanism 20 , the second adjustment and limiting mechanism 30 and the third adjustment and limiting mechanism 40 are adjustable, they can be adapted to fix batteries 50 of different models and have a wide range of uses.

[0052] It should be noted that, in the embodiment of the present invention, the X-axis direction refers to Figure 1 The arrow in the middle points to the "X-axis direction", and the Y-axis direction refers to Figure 1 The arrow in the middle points to the "Y-axis direction", and the Z-axis direction refers to Figure 1 The arrow in the middle points to the "Z-axis direction".

[0053] like Figures 1 to 2 As shown, in one embodiment, the first adjustment limit assembly includes a first adjustment bolt 21 and at least one first nut 23. The first adjustment bolt 21 is adjustably threadedly connected to the positioning plate 22 in the Z-axis direction. The free end of the first adjustment bolt 21 presses against the top surface of the battery 50. The at least one first nut 23 is respectively threadedly connected to the first adjustment bolt 21 and respectively pressed against the upper side and / or lower side of the positioning plate 22.

[0054] Specifically, the first adjustment and limiting assembly is provided with two first nuts 23 , which are respectively threadedly connected to the first adjustment bolt 21 and respectively pressed against the upper side and the lower side of the positioning plate 22 .

[0055] When the first adjusting bolt 21 needs to be adjusted, first loosen the two first nuts 23 on the upper and lower sides of the positioning plate 22, then loosen the first adjusting bolt 21 to move the first adjusting bolt 21. When the first adjusting bolt 21 is moved to a suitable position, re-tighten the first adjusting bolt 21 and the positioning plate 22, and finally tighten the two first nuts 23. When the first adjusting bolt 21 needs to be disassembled, first loosen the two first nuts 23, then loosen the first adjusting bolt 21, and remove the first adjusting bolt 21 and the two first nuts 23 from the positioning plate 22 to achieve the disassembly of the first adjusting bolt 21 and the positioning plate 22. The process of assembling the first adjusting bolt 21 is the opposite of the process of disassembling the first adjusting bolt 21, and will not be repeated here.

[0056] The first adjusting bolt 21 is threadedly engaged with the positioning plate 22 to adjust the position of the first adjusting bolt 21 in the Z-axis direction, thereby adapting to different types of batteries 50 for limiting the position in the Z-axis direction. The first nut 23 is connected to the first adjusting bolt 21 to lock the first adjusting bolt 21 to prevent the connection between the first adjusting bolt 21 and the positioning plate 22 from being loose. The first adjustment limit mechanism 20 has a simple and reasonable structure, is easy to adjust, and is easy to disassemble and assemble.

[0057] Of course, when the space of the box body 10 in the Z-axis direction is limited, the top plate of the box body 10 can be selected as the positioning plate 22, and the position of the first adjusting bolt 21 in the Z-axis direction can be adjusted through the top plate; thereby adjusting the position of the first adjusting bolt 21 in the Z-axis direction to adapt to the installation of different types of batteries 50; when the space of the box body 10 in the Z-axis direction is sufficient, and the top surface of the battery 50 to be fixed in the box body 10 is at a large distance from the top surface of the box body 10, if the top plate of the box body 10 is used as the positioning plate 22, a very long first adjusting bolt 21 is required for fixing it, and a positioning plate 22 needs to be set in the box body 10, and it is more appropriate to fix the battery 50 by cooperating with the positioning plate 22 and the first adjusting bolt 21.

[0058] like Figure 1 As shown in Figure 2, in one embodiment, the second adjustment limit mechanism 30 includes a second adjustment limit component, which is passed through the side plate 12 on its side to adjustably press the battery 50 in the X-axis direction and make the battery 50 press tightly against the side plate 12 in that direction.

[0059] By cooperating with the side plate 12, the battery 50 can be adjusted in the X-axis direction to limit the position of different types of batteries 50 in the X-axis direction. It can adapt to the fixation of different types of batteries 50 and has a wide range of uses.

[0060] like Figures 1 to 2 As shown, in one embodiment, the second adjustment limit assembly includes a second adjustment bolt 31 and at least one second nut 32. The second adjustment bolt 31 is adjustably threadedly connected to the side plate 12 where it is located in the X-axis direction, and the free end of the second adjustment bolt 31 presses against the battery 50. At least one second nut 32 is respectively threadedly connected to the second adjustment bolt 31 and respectively pressed against the inner side and / or outer side of the side plate 12 where the second adjustment bolt 31 is located.

[0061] Specifically, the second adjustment limit assembly is provided with two second nuts 32 , which are respectively threadedly connected to the second adjustment bolt 31 and respectively pressed against the inner side and the outer side of the side plate 12 where the second adjustment bolt 31 is located.

[0062] When the second adjusting bolt 31 needs to be adjusted, first loosen the two second nuts 32 on the inner and outer sides of the side plate 12 where the second adjusting bolt 31 is located, then loosen the second adjusting bolt 31 to move the second adjusting bolt 31; when the second adjusting bolt 31 is moved to a suitable position, re-tighten the second adjusting bolt 31 and the side plate 12 where it is located, and finally tighten the two second nuts 32. When the second adjusting bolt 31 needs to be removed, first loosen the two second nuts 32, then loosen the second adjusting bolt 31, and remove the second adjusting bolt 31 and the two second nuts 32 from the side plate 12 where the second adjusting bolt 31 is located. The process of assembling the second adjusting bolt 31 is the opposite of the process of disassembling the second adjusting bolt 31, and will not be repeated here.

[0063] The second adjusting bolt 31 is threadedly engaged with the side plate 12 to adjust the position of the second adjusting bolt 31 in the X-axis direction, thereby adapting to different types of batteries 50 for limiting the position in the X-axis direction. The second nut 32 is connected to the second adjusting bolt 31 to lock the second adjusting bolt 31 to prevent the second adjusting bolt 31 from being loosely connected to the side plate 12. The second adjustment limiting mechanism 30 has a simple and reasonable structure, is easy to adjust, and is easy to disassemble and assemble.

[0064] like Figure 1 As shown, in one embodiment, the third adjustment limit mechanism 40 includes a third adjustment limit component, which passes through the side plate 12 on its side to adjustably press the battery 50 in the Y-axis direction and make the battery 50 press tightly against the side plate 12 in that direction.

[0065] By cooperating with the side plate 12, the battery 50 can be adjusted in the Y-axis direction to limit the position of different types of batteries 50 in the Y-axis direction. It can adapt to the fixation of different types of batteries 50 and has a wide range of uses.

[0066] like Figure 1 As shown, in one embodiment, the third adjustment limit assembly includes a third adjustment bolt 41 and at least one third nut 42. The third adjustment bolt 41 is threadably connected to the side plate 12 where it is located in the Y-axis direction, and the free end of the third adjustment bolt 41 presses against the battery 50. At least one third nut 42 is respectively threadedly connected to the third adjustment bolt 41 and respectively pressed against the inner side and / or outer side of the side plate 12 where the third adjustment bolt 41 is located.

[0067] Specifically, the third adjustment limit assembly is provided with two third nuts 42 , which are respectively threadedly connected to the third adjustment bolt 41 and respectively pressed against the inner side and the outer side of the side plate 12 where the third adjustment bolt 41 is located.

[0068] When the third adjusting bolt 41 needs to be adjusted, first loosen the two third nuts 42 on the inner and outer sides of the side plate 12 where the third adjusting bolt 41 is located, then loosen the third adjusting bolt 41 to move the third adjusting bolt 41; when the third adjusting bolt 41 is moved to a suitable position, re-tighten the third adjusting bolt 41 and the side plate 12 where the third adjusting bolt 41 is located, and finally tighten the third nut 42. When the third adjusting bolt 41 needs to be removed, first loosen the third nut 42, then loosen the third adjusting bolt 41, and remove the third adjusting bolt 41 and the two third nuts 42 from the side plate 12 where the third adjusting bolt 41 is located to achieve the removal of the third adjusting bolt 41 from the side plate 12 where the third adjusting bolt 41 is located; the process of assembling the third adjusting bolt 41 is the opposite of the process of disassembling the third adjusting bolt 41, and will not be repeated here.

[0069] The third adjusting bolt 41 is threadedly engaged with the side plate 12 on the side where the third adjusting bolt 41 is located, so as to adjust the position of the third adjusting bolt 41 in the Y-axis direction, thereby adapting to different types of batteries 50 for limiting the position in the Y-axis direction. The third nut 42 is connected to the third adjusting bolt 41 to lock the third adjusting bolt 41 to prevent the connection between the third adjusting bolt 41 and the side plate 12 from being loose. The third adjustment limiting mechanism 40 has a simple and reasonable structure, is easy to adjust, and is easy to disassemble and assemble.

[0070] The second adjustment limit mechanism 30 and the third adjustment limit mechanism 40 are arranged adjacent to each other, and can respectively press the two adjacent side surfaces of the battery 50, so that the positions of the second adjustment limit mechanism 30 and the third adjustment limit mechanism 40 are closer, which is convenient for disassembly and assembly together.

[0071] like Figure 2 As shown, in one embodiment, the third adjustment and limiting mechanism 40 includes an elastic limiting plate 43. The elastic limiting plate 43 is U-shaped and is suitable for covering the top surface and two corresponding side surfaces of the battery 50 in the Y direction. The battery 50 is abutted against the opposite sides of the box 10 via the elastic limiting plate 43. The elastic limiting plate 43 can limit the position of the battery 50 in the Y direction. The elastic limiting plate 43 has a simple and reasonable structure and facilitates positioning of the battery.

[0072] In addition, since the elastic limiting plate 43 has a certain degree of elasticity, it can adapt to different types of batteries 50 for limiting in the Y-axis direction; if the size of the new battery 50 replaced is larger than that of the previous battery 50 in the Y-axis direction, and exceeds the applicable range of the elastic limiting plate 43, a new and suitable elastic limiting plate 43 needs to be replaced.

[0073] Specifically, the elastic limiting plate 43 can be made of oil-resistant rubber, which can not only play the above-mentioned limiting role, but also play the role of insulation and shock absorption.

[0074] like Figures 1 to 2 As shown, in one embodiment, the first adjustment and limiting assembly indirectly presses the battery 50 through the elastic limiting plate 43 .

[0075] The first adjustment limit mechanism 20 indirectly presses the battery 50 against the bottom wall of the box body 10 through the elastic limit plate 43. On the one hand, it can fix the elastic limit plate 43, and on the other hand, it can prevent the first adjustment limit mechanism 20 from directly contacting the top surface of the box body 10, thereby protecting the box body 10.

[0076] In one embodiment, the second adjustment and limiting mechanism 30 may also have the same or similar structure as the elastic limiting plate 43 used in the third adjustment and limiting mechanism 40. Specifically, the second adjustment and limiting mechanism 30 includes a U-shaped elastic limiting plate adapted to cover the top surface and corresponding side surfaces of the battery 50 in the X-axis direction. The elastic limiting plate abuts the battery 50 against opposite sides of the housing 10. The elastic limiting plate can limit the position of the battery 50 in the X-axis direction. The use of the elastic limiting plate provides a simple and reasonable structure and facilitates battery positioning.

[0077] like Figure 1 As shown, in one embodiment, the housing 10 has a rotatable side door 13. A flange 14 is provided on the side of the housing 10 where the side door 13 is located. The side door 13 is hingedly connected to the flange 14. The flange 14 and the side door 13 together form a side panel 12 on that side. The provision of the side door 13 facilitates opening the housing 10 (opening the side door 13 downward opens the housing 10), facilitating installation and removal of the battery 50.

[0078] like Figure 1 As shown, in one embodiment, an insulating shock-absorbing pad 60 is provided on the bottom plate 11 , and the insulating shock-absorbing pad 60 extends to the inner side of the side plate 12 to protect the pressing part of the battery 50 .

[0079] Specifically, the insulating shock-absorbing pad 60 includes a rubber layer. The rubber layer is made of oil-resistant rubber, and other flexible, shock-absorbing, and insulating materials can be used instead.

[0080] An insulating shock-absorbing pad 60 is provided on the bottom wall of the box body 10, which can prevent the battery 50 from directly contacting the bottom wall of the box body 10, thereby playing the role of insulation and shock absorption. The insulating shock-absorbing pad 60 extends to the inner side of the side panel 12, which can prevent the battery 50 from directly contacting the side panel 12 of the box body 10 and the adjustment limit mechanism (the second adjustment limit mechanism 30 or the third adjustment limit mechanism 40), thereby playing the role of insulation and shock absorption.

[0081] According to an embodiment of the present invention, on the other hand, a working machine is provided, including a battery and a battery fixing device, wherein the battery is fixed in a box of the battery fixing device.

[0082] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
