DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a battery device for an electric tool, comprising a box body 1, a carrying mechanism 2 for earthquake-proof protection of control and power supply components is arranged at the bottom of the inner cavity of the box body 1, a connecting mechanism 3 is arranged above the carrying mechanism 2, a covering mechanism 4 is arranged at the top of the box body 1, a lateral clamping mechanism 5 is arranged at the top of the covering mechanism 4, the carrying mechanism 2 comprises a first spring 21, and the first spring 21 is respectively welded to the four sides of the bottom of the inner cavity of the box body 1;

[0025] A mounting plate 22 is welded to the top of the first spring 21, a damper 23 is fixedly installed at the center of the bottom of the box body 1, the top of the damper 23 is fixed to the bottom of the mounting plate 22, vertical rods 24 are fixedly installed around the bottom of the inner cavity of the box body 1, and a limiting groove 25 is provided on the inner side of the vertical rod 24. The mounting plate 22 and the vertical rod 24 are slidably connected, which can carry the power supply battery and the control board while also assisting in their installation, and achieve the effect of anti-seismic buffer protection.

[0026] First, place the battery case 31. At this time, align the four corners of the battery case 31 with the limiting grooves 25 opened by the vertical rod 24. Then place the battery case 31 downward until the battery case 31 is located on the top of the mounting plate 22. Bolt it to the top of the mounting plate 22 to achieve the limited installation of the battery case 31:

[0027] Since the battery case 31 is equipped with a battery, its weight will press the damper 23 and the first spring 21 downward. When the battery case 31 falls, the gravity collision will generate an impact force, so the mounting plate 22 will directly press the damper 23 and the first spring 21, and the elasticity of the first spring 21 and the damping property of the damper 23 are used to achieve anti-seismic buffering protection to avoid damage and ensure the stability of operation;

[0028] When the mounting plate 22 moves up and down, it will slide outside the vertical rod 24 to cooperate with the vertical rod 24 to complete the vertical movement and ensure stability.

[0029] like Figure 3 and 4 As shown, the connecting mechanism 3 includes a battery shell 31, which is bolted to the top of the mounting plate 22, and a first circuit board 32 is bolted to the top of the battery shell 31. The inner wall of the box body 1 is fixedly mounted with a heat dissipation fin group 33, which is convenient for power control and power supply.

[0030] The battery shell 31 is used to store batteries, while the mounting plate 22 is conducive to the first circuit board 32 for power control, and the setting of the heat dissipation fin group 33 can complete the auxiliary heat dissipation to ensure the adsorption and discharge of the heat generated. The first circuit board 32 is installed in the same way as the battery shell 31 as mentioned above, placed from top to bottom, and it is in a limited sliding state until it contacts the top of the battery shell 31, and finally tightened again by bolts.

[0031] Preferably, the covering mechanism 4 includes a mounting assembly and a locking assembly. The mounting assembly is arranged on the top of the box body 1, and the locking assembly is located at the lower part of the inner side of the mounting assembly.

[0032] like Figure 2 As shown, the installation assembly includes a cover plate 41 and a limit block 42. The cover plate 41 covers the top of the box body 1, and the limit blocks 42 are fixedly installed on both sides of the bottom of the inner cavity of the cover plate 41. The cover plate 41 is used to cover and seal, and the cover plate 41 and the box body 1 are locked by bolts. The limit blocks 42 can limit the second circuit board 43 when it is installed.

[0033] like Figure 2 As shown, the locking assembly includes a second circuit board 43 and a locking screw 44. The second circuit board 43 is sleeved on the outer side of the limit block 42, and the locking screw 44 is threadedly connected to the bottom end of the limit block 42.

[0034] During installation;

[0035] Directly align the matching hole opened on the second circuit board 43 with the limit block 42 so that it is sleeved on the outside of the limit block 42, and then rotate the locking screw block 44, and use the locking screw block 44 to be threadedly connected with the limit block 42 until the top of the locking screw block 44 contacts the second circuit board 43 to lock it.

[0036] Furthermore, the lateral clamping mechanism 5 includes a supporting component and an anti-slipping component. The supporting component is arranged on both sides of the top of the cover plate 41, and the anti-slipping component is arranged on the inner side of the supporting component.

[0037] like Figure 1 As shown, the support assembly includes a side plate 51 and a second spring 52. The side plates 51 are fixedly mounted on both sides of the top of the cover plate 41, and the second spring 52 is welded to both ends of the inner side of the cover plate 41 to play a role of elastic support.

[0038] like Figure 1 As shown, the anti-drop assembly includes a push plate 53, a slide bar 54 and a cross bar 55. The push plate 53 is fixedly mounted on the inner end of the second spring 52, the slide bar 54 is fixedly mounted on the inner side of the push plate 53, and the cross bar 55 is fixedly mounted on both ends of the outer side of the push plate 53. The cross bar 55 slides through the side plate 51, which is conducive to sliding connection with the bottom end of the power tool, that is, the installation end, while elastically pressing against it, thereby increasing its connectivity and preventing it from falling off.

[0039] When using:

[0040] The bottom end of the electric tool is located above the cover plate 41, and then the cover plate 41 is inserted and fixed to the bottom end of the electric tool in a horizontal insertion manner, and the bottom of the electric tool is provided with a power connection sheet and a notch matched with the cover plate 41, and a slide groove matched with the slide bar 54;

[0041] During installation, it is necessary to push the slide bars 54 on both sides at the same time to drive the push plate 53 to squeeze the second spring 52, so as to expand the distance between the two sets of slide bars 54, and at the same time be used to compress the second spring 52, and facilitate alignment with the slide groove at the bottom of the power tool to match the slide bar 54. At this time, the installation work can be completed by directly moving horizontally to a position where it cannot be moved.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
