[0028] In order to facilitate a better understanding of the purpose, structure, characteristics and functions of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods.

[0029] See also Figure 1 , Figure 5 and Figure 6 The battery holder of the utility model is used to accommodate a battery D, including a seat body 1, a positive electrode spring sheet 2 and a negative electrode spring sheet 3 respectively accommodated in the seat body 1 to be electrically connected with the battery D, and a cover body 5 covered on the seat body 1 to cover the battery D.

[0030] like Figure 1 , Figure 8 and Fig. 9As shown, the base body 1 is made of insulating material, and has a receiving cavity 12 with an opening at the top. The battery D is received in the receiving cavity 12. The base body 1 is provided with a wall 11 on the outer periphery of the receiving cavity 12. The wall 11 is provided with two arc-shaped tracks 113 protruding outwardly. The wall 11 is provided with a clearance channel 116 on one side of each track 113. Each track 113 is provided with a first inclined surface 1131 inclined downward in a direction away from the clearance channel 116 on the side connected to the clearance channel 116. Each track 113 is provided with a first clamping surface 1133 on the other side away from the clearance channel 116. The lower edge of the track 113 is lower than the first clamping surface 1133. A second inclined surface 1132 connects the lower edge of the track 113 and the corresponding first clamping surface 1133. The angle between the second inclined surface 1132 and the first clamping surface 1133 is an obtuse angle. The two opposite sides of the fence 11 protrude outward to form a mounting portion 13, and the fence 11 is provided with two first blocks 114 and two second blocks 115 protruding outward, each first block 114 correspondingly connects the mounting portion 13 and the clearance channel 116, and each second block 115 correspondingly connects the mounting portion 13 and the first clamping surface 1133, thereby enhancing the strength of each first block 114 and each second block 115; further, the height of each first block 114 and each second block 115 is flush with the height of the track 113 for easy molding, and the width of each first block 114 is smaller than the width of each second block 115. A support portion 111 protrudes upward from the fence 11 (in other embodiments, the support portion 111 may also protrude downward from the main body 51); in this embodiment, the support portion 111 is block-shaped, and in other embodiments, the support portion 111 may also be set to a convex hull or other shapes, which is not specifically limited by the present invention. The wall 11 extends inward to have a plurality of stoppers 112 to stop the battery D from moving upward and prevent the battery D from falling out of the receiving cavity 12 . Along the circumference of the wall 11 , the stoppers 112 overlap with the first engaging surfaces 1133 .

[0031] like Figure 1 and Figure 6 As shown, the positive spring sheet 2 and the negative spring sheet 3 are both installed on the installation portion 13, and the positive spring sheet 2 and the negative spring sheet 3 respectively enter the receiving cavity 12 to electrically contact the battery D. The positive spring sheet 2 abuts the side surface of the battery D, and the negative spring sheet 3 has an elastic contact portion 31 to elastically abut the lower surface of the battery D.

[0032] like Figure 1 , Figure 4 and Fig.10As shown, the cover body 5 is made of insulating material, and has a main body 51 and two extensions 52 extending downward from opposite sides of the main body 51. A slider 521 is convexly provided on the inner side of each extension 52. A second clamping surface 5211 is provided at the upper end of each slider 521 to be engaged with the corresponding first clamping surface 1133. A first guide surface 5212 is provided downwardly and tilted away from each other from opposite ends of each second clamping surface 5211, and a second guide surface 5213 is provided downwardly and tilted toward each other from the lower end of each first guide surface 5212. A plurality of positioning blocks 522 are convexly provided on the inner side of each extension 52. Each positioning block 522 is located on the upper side of the slider 521 and each positioning block 522 is spaced apart from the slider 521 in the vertical direction. The upper end of each positioning block 522 is integrally connected to the lower surface of the main body 51 to enhance the strength of the extension 52. Furthermore, each positioning block 522 is staggered with the slider 521 in the vertical direction. A protruding portion 511 is protruded downwardly from the middle of the main body 51 .

[0033] like Figures 2 to 7As shown, when the cover body 5 begins to be assembled, the cover body 5 is placed downward on the top of the base body 1 to cover the accommodating cavity 12, and the two second guide surfaces 5213 respectively guide the two sliders 521 to pass through the two make way channels 116 downward accordingly, and the two first stoppers 114 respectively prevent the two sliders 521 from colliding with the mounting portion 13. When the cover body 5 starts to rotate, the cover body 5 is pressed downward, and the support portion 111 abuts against the main body 51 to form a fulcrum, and the main body 51 elastically deforms downward, so that the two first guide surfaces 5212 respectively cooperate with the two first inclined surfaces 1131 to guide the two sliders 521 to slide along the two first inclined surfaces 1131 to the lower edge of the corresponding track 113 and continue to slide along the lower edge of the corresponding track 113. The force of the two rails 113 pressing the two sliders 521 downward is transmitted to the main body 51 through the setting of the support portion 111, so that the force arm is extended from the extension portion 52 to the main body 51, so as to avoid the two extension portions 52 being fatigued, deformed or even broken due to concentrated force, thereby ensuring the structural stability of the battery holder. During the rotation of the cover 5, the protrusion 511 of the main body 51 presses downward against the upper surface of the battery D, thereby causing the elastic contact portion 31 to elastically deform downward, thereby ensuring the contact stability between the negative electrode spring sheet 3 and the battery D. When the cover 5 rotates until the two sliders 521 are aligned with the two first clamping surfaces 1133 in the vertical direction, the cover 5 is released, and the restoring force of the cover 5 and the negative electrode spring sheet 3 press upward against the battery D. The force of the battery D further pressing upward against the protrusion 511 acts together to cause the two sliders 521 to move upward, and the two second inclined surfaces 1132 cooperate with the two first guide surfaces 5212 to guide the two sliders 521 so that the two second clamping surfaces 5211 are upwardly corresponding to the two first clamping surfaces 1133. The two second stoppers 115 stop the two sliders 521 from continuing to slide, and at this time the main body 51 returns to its original shape. Furthermore, during the rotation of the cover body 5, the multiple positioning blocks 522 all slide along the upper edge of the corresponding track 113, and the positioning blocks 522 and the slider 521 jointly limit the displacement of the extension portion 52 in the up and down directions; further, the rotation angle of the cover body 5 relative to the base body 1 is greater than 90 degrees, which increases the difficulty of unlocking and makes it difficult for children to open the cover body 5 to remove the battery D.

[0034] When it is necessary to take out the battery D, it is necessary to apply a sufficiently large force to press the cover body 5 downward while rotating the cover body 5 in the opposite direction to make the main body 51 elastically deformed, and the two first clamping surfaces 1133 leave the two second clamping surfaces 5211 and slide along the lower edge of the track 113 in the opposite direction to the previous direction. The track 113 presses the slider 521 downward. During this process, it is necessary to keep pressing the cover body 5 until the two sliders 521 are aligned with the two clearance channels 116 up and down, and then lift the cover body 5 upward to make the two sliders 521 correspondingly withdraw from the two clearance channels 116 upward, and then operate the battery D to make it leave the accommodating cavity 12. Such step-by-step operation meets the safety requirements of the battery holder, making it difficult for children to open the cover body 5, thereby preventing children from accidentally swallowing the battery D.

[0035] In summary, the battery holder of the utility model has the following beneficial effects:

[0036] (1) When it is necessary to unlock the cover 5 to remove the battery D, it is necessary to apply a large force to press down the cover 5 to elastically deform the main body 51 while rotating the cover 5 to separate the cover 5 from the base 1. Such steps meet the safety requirements of the battery holder, increase the difficulty of unlocking, and make it difficult for children to open the cover 5 to remove the battery D, thereby preventing children from accidentally swallowing the battery D.

[0037] (2) The first inclined surface 1131 guides the slider 521 to slide to the lower edge of the track 113. At least one of the main body 51 and the seat body 1 is provided with a support portion 111 to form a fulcrum. The main body 51 is elastically deformed to allow the slider 521 to slide along the first inclined surface 1131 to the lower edge of the track 113 and continue to slide along the lower edge of the track 113. The downward pressure exerted by the track 113 on the slider 521 is transmitted to the main body 51 through the support portion 111, so that the force arm is extended from the extension portion 52 to the main body 51, thereby preventing the extension portion 52 from being subjected to excessive stress concentration and fatigue deformation or even fracture, thereby ensuring the structural stability of the battery holder.

[0038] (3) The positioning portion and the slider 521 slide along the upper edge and the lower edge of the corresponding track 113 respectively to jointly limit the displacement of the extension portion 52 in the up and down directions; the upper end of the positioning block 522 is integrally connected to the lower surface of the main body 51 to enhance the strength of the extension portion 52, and each positioning block 522 and the corresponding slider 521 are staggered in the upper and lower directions to avoid the portion of the extension portion 52 located between the positioning block 522 and the slider 521 from being broken due to excessive concentrated stress.

[0039] The above detailed description is only an explanation of the preferred embodiment of the utility model, and does not limit the patent scope of the utility model.
