[0027] 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.

[0028] See also Figures 1 to 3 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 and electrically connected to the battery D, and a cover body 5 installed on the seat body 1.

[0029] like Figure 2 and Figure 3As shown, the seat body 1 is made of insulating material and is roughly circular. The seat body 1 has a cavity 13 with an opening at the top. The battery D is accommodated in the cavity 13. A mounting portion 14 is protruded outward on one side of the seat body 1. The mounting portion 14 is penetrated with a mounting groove 141 along the up-down direction. A disassembly groove 19 is penetrated on the side of the seat body 1 away from the mounting portion 14. The side of the battery D is exposed in the disassembly groove 19 to facilitate the disassembly of the battery D from the disassembly groove 19. Two first slide grooves 15 are recessed from the inner circumferential surface of the seat body 1 at intervals. Both first slide grooves 15 are arc-shaped. In the circumferential direction of the seat body 1, the two first slide grooves 15 are respectively located on both sides of the mounting portion 14. The seat body 1 is protruded with a first locking portion 151 corresponding to each first slide groove 15. Two second locking portions 171 are protruded outward from the periphery of the seat body 1 at intervals. In the radial direction of the seat body 1, the two second locking portions 171 are respectively located on the outside of the two first locking portions 151. The base body 1 is provided with a first side wall 11 and a second side wall 12 on both sides of the mounting portion 14, respectively. The first side wall 11 and the second side wall 12 are respectively located on both sides of the disassembly groove 19, and first slide grooves 15 are respectively recessed on the inner sides of the first side wall 11 and the second side wall 12, and the two first slide grooves 15 penetrate upwardly through the top surfaces of the first side wall 11 and the second side wall 12. The inner side surface of the first slide groove 15 provided on the first side wall 11 away from the mounting portion 14 is convexly provided toward the cavity 13 to form a first locking portion 151, and the inner side surface of the first slide groove 15 provided on the second side wall 12 close to the mounting portion 14 is convexly provided toward the cavity 13 to form another first locking portion 151. In this embodiment, the two first locking portions 151 are both convex rib-shaped. The top of the first side wall 11 and the top of the second side wall 12 are both concavely provided with two first through grooves 16 corresponding to the positions on both sides of the two first locking parts 151. The two first through grooves 16 are arranged to penetrate in the radial direction, and the lower edge of each first through groove 16 is located at the lower side of the corresponding first locking part 151 to enhance the elasticity of the first locking part 151, which is conducive to the elastic deformation of the first locking part 151. The outer side surfaces of the first side wall 11 and the second side wall 12 are respectively concavely provided with second slide grooves 17. The two second slide grooves 17 are both arranged in an arc shape and penetrate downwardly through the bottom surfaces of the first side wall 11 and the second side wall 12 respectively. The two second slide grooves 17 are respectively located at the lower side of the two first slide grooves 15 to ensure the strength of the first side wall 11 and the second side wall 12, and to avoid the first slide groove 15 and the second slide groove 17 being arranged at the same height, which may cause the first side wall 11 and the second side wall 12 to be too thin and break. The second slide groove 17 provided on the first side wall 11 is protruded outward on the side away from the mounting portion 14 to form a second locking portion 171, and the second slide groove 17 provided on the second side wall 12 is protruded outward on the side close to the mounting portion 14 to form another second locking portion 171. Both second locking portions 171 are in the shape of convex ribs. When viewed from top to bottom, the projection of the first locking portion 151 and the projection of the second locking portion 171 located on the same side of the mounting portion 14 are aligned for easy molding.Two second through slots 18 are provided along the radial direction at the positions on both sides of the first side wall 11 and the second side wall 12 corresponding to the two second locking parts 171, respectively. The upper edge of each second through slot 18 is flush with the upper surface of the corresponding second locking part 171, and the lower edge of each second through slot 18 is located at the lower side of the corresponding second locking part 171, so as to enhance the elasticity of the second locking part 171 and facilitate the elastic deformation of the second locking part 171. Further, each first through slot 16 is aligned with each second through slot 18 in the up-down direction to enhance the elasticity of the first side wall 11 and the second side wall 12 provided with the first locking part 151 and the second locking part 171. The two second locking parts 171 are respectively located on the outer sides of the two first locking parts 151, and the two second locking parts 171 are also respectively located at the lower sides of the two first locking parts 151. One end of the two second slide grooves 17 away from the respective second locking parts 171 respectively penetrates upward through the top surface of the first side wall 11 and the second side wall 12 to form a mounting notch 172.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, the positive spring piece 2 and the negative spring piece 3 are both accommodated in the base body 1. Specifically, the positive spring piece 2 is installed in the installation groove 141 of the installation portion 14 and partially extends into the cavity 13 to respectively abut against the side surface of the battery D and the top surface of the battery D, and the negative spring piece 3 is installed at the bottom of the base body 1 and extends into the cavity 13 to elastically abut against the bottom surface of the battery D.

[0031] like Figure 2 , Figure 3 and Figure 8As shown, the cover body 5 is made of insulating material. The cover body 5 has a main body 51 and an extension part 52 extending downward from the outer edge of the main body 51. The extension part 52 extends continuously to form an arc shape. The main body 51 has two opposite sides corresponding to the extension part 52, and a clearance groove 512 is respectively penetrated along the up and down direction. The two clearance grooves 512 both extend downward to the extension part 52. From the inner edge of each clearance groove 512, a first clamping structure 511 is convexly formed outwardly. The two first clamping structures 511 are both block-shaped. There is a gap between the opposite side edges of each first clamping structure 511 and the opposite side edges of the corresponding clearance groove 512, so as to reserve a deformation gap for the first clamping structure 511 and enhance the elasticity of the first clamping structure 511; the outer edge of each first clamping structure 511 is concave inwardly to form a first clamping groove 5111. A second engaging structure 522 is provided on opposite sides of the inner side surface of the extension portion 52. Each second engaging structure 522 includes two sliders 5221 formed by being spaced apart from the inner side surface of the extension portion 52 and a second engaging groove 5222 located between the two sliders 5221. The heights of the two sliders 5221 of each second engaging structure 522 are flush and the shapes are consistent. In the circumferential direction of the seat body 1, the distance between the outer edges of the two sliders 5221 of each second engaging structure 522 is less than the width of each mounting notch 172, so that the two sliders 5221 of each second engaging structure 522 can be installed downward from the corresponding mounting notch 172 to the second slide groove 17. When viewed from top to bottom, the projections of the two first engaging structures 511 and the projections of the two second engaging structures 522 are located on the same straight line, which is convenient for molding and saves space, so that there is enough space between the cover body 5 and the seat body 1 to ensure that the cover body 5 can rotate 90 degrees relative to the seat body 1. Further, each first engaging structure 511 has a gap with the corresponding second engaging structure 522 in the radial direction. The extension portion 52 has two thin portions 521 on opposite sides thereof. The thickness of the two thin portions 521 is smaller than the thickness of other parts of the extension portion 52. The two second engaging structures 522 are respectively disposed on the inner side surfaces of the two thin portions 521, which is beneficial to enhance the elasticity of the two second engaging structures 522 and improve their service life. Figure 6When the cover body 5 begins to be assembled, the cover body 5 is covered on the top of the base body 1, and the two second engaging structures 522 of the extension part 52 are respectively installed downward from the two installation notches 172 to the corresponding second slide grooves 17, and the two first engaging structures 511 slide in the two first slide grooves 15 respectively, and the two second engaging structures 522 slide in the two second slide grooves 17 respectively, and the first engaging structures 511 are stopped from moving downward by the bottom surfaces of the two first slide grooves 15, so that there is a gap between the bottom surface of the main body 51 and the top surface of the battery D, so as to prevent the main body 51 from pressing the battery D downward and then pressing the negative electrode spring sheet 3 to cause elastic fatigue of the negative electrode spring sheet 3, and the top surfaces of the two second slide grooves 17 jointly stop the second engaging structures 522 from moving upward, so as to ensure that the cover body 5 will not separate from the base body 1 upward during rotation. Then, the cover body 5 is rotated 90 degrees relative to the base body 1, so that the first slots 5111 of the two first engaging structures 511 are respectively buckled and fixed with the two first locking parts 151, and the second slots 5222 of the two second engaging structures 522 are respectively buckled and fixed with the two second locking parts 171, so as to fix the cover body 5 to the base body 1. Figure 4 , Figure 5 and Figure 7As shown, at this time, the wall thickness parts of the first side wall 11 and the second side wall 12 corresponding to the first locking part 151 enter the gap between the two first engaging structures 511 and the corresponding second engaging structures 522 respectively, so as to make way for the parts of the first side wall 11 and the second side wall 12 provided with the first locking part 151, and at the same time, the first engaging structure 511 and the corresponding second engaging structure 522 jointly clamp the parts to prevent the cover body 5 from being displaced, and the parts of the first side wall 11 and the second side wall 12 provided with the first locking part 151 are respectively exposed in the two making way grooves 512, so as to facilitate the observation of the fixing conditions of the two first engaging structures 511 and the corresponding first locking part 151. Through the internal and external snap fit, the cover body 5 is prevented from being offset to one side due to the center of gravity offset during the rotation process relative to the base body 1, so that the cover body 5 and the base body 1 cannot achieve the fixing effect. Specifically, when the cover body 5 rotates relative to the base body 1, the first engaging structure 511 of the cover body 5 and the second engaging structure 522 adjacent thereto are respectively located at the inner and outer sides of the first side wall 11 or the second side wall 12, and the first engaging structure 511 and the second engaging structure 522 adjacent to each other jointly clamp the first side wall 11 or the second side wall 12, and when the cover body 5 has a tendency to excessively deviate toward the first locking portion 151 on the side close to the mounting portion 14, the second locking portion 171 on the side away from the mounting portion 14 resists against the second engaging structure 522 to stop the cover body 5 from continuing to deviate; when the cover body When the cover 5 has a tendency to excessively deviate toward the first locking portion 151 on the side away from the mounting portion 14, the second locking portion 171 on the side close to the mounting portion 14 abuts against the second engaging structure 522 to stop the cover 5 from further deviating; the inner and outer engaging structures cooperate with the inner and outer locking portions to prevent the cover 5 from deviating toward one side, thereby ensuring that the two first engaging structures 511 are locked in place with the corresponding first locking portions 151, and the two second engaging structures 522 are locked in place with the corresponding second locking portions 171, thereby ensuring the locking effect of the cover 5 and the seat 1, and improving the structural stability of the battery holder. The projections of the two first engaging structures 511 and the two second engaging structures 522 along the vertical direction, as well as the projections of the two first locking portions 151 and the two second locking portions 171 along the vertical direction are all located in the same straight line, so that the first engaging structure 511 and the corresponding first locking portion 151 and the second engaging structure 522 and the corresponding second locking portion 171 are simultaneously locked, thereby increasing the holding force between the cover body 5 and the seat body 1, preventing children from twisting the cover body 5, and also effectively preventing the cover body 5 from deflecting to one side. Two first through slots 16 are provided on both sides of each first locking portion 151, and two second through slots 18 are provided on both sides of each second locking portion 171, which is conducive to the elastic deformation of the part of the seat body 1 provided with the first locking portion 151 and the second locking portion 171, and preventing the first locking portion 151 and the second locking portion 171 from being broken due to strong extrusion when they are locked with the corresponding first engaging structure 511 and the second engaging structure 522.There is a gap between the two side edges of the first engaging structure 511 and the two side edges of the corresponding clearance groove 512, and the two second engaging structures 522 are respectively arranged on the inner side surfaces of the two thin parts 521, which is also conducive to enhancing the elasticity of the first engaging structure 511 and the second engaging structure 522. When the cover body 5 is rotated into place, the extension part 52 covers the disassembly groove 19 to prevent children from removing the battery D from the disassembly groove 19.

[0032] When it is necessary to remove the battery D, a certain torque must first be reached to disengage each first engaging structure 511 from the corresponding first locking portion 151, and each second engaging structure 522 from the corresponding second locking portion 171, and then the cover body 5 is driven to rotate 90 degrees in the opposite direction to the previous direction until the two second engaging structures 522 are aligned with the corresponding installation notches 172 in the up and down directions. Then, the cover body 5 is lifted upwards, and after the cover body 5 is separated from the base body 1, the battery D is taken out. The step-by-step operation makes it difficult for children to easily remove the battery D, thereby preventing children from accidentally swallowing the battery D.

[0033] In other embodiments, in order to prevent the first locking portion 151 from being worn, the outer surface of each first locking portion 151 is covered with a metal sheet to prevent the first locking portion 151 from being squeezed and worn, causing insulating debris to fall into the container. The metal sheet can be fixed to the outer surface of the first locking portion 151 by assembly or injection molding, and the present invention is not limited to this.

[0034] In other embodiments, the projections of the two first locking structures 511 along the up-down direction may not be on the same straight line as the projections of the two second locking structures 522 along the up-down direction, that is, each first locking structure 511 is staggered inside and outside with the adjacent second locking structure 522, and correspondingly, each first locking portion 151 is also staggered inside and outside with the adjacent second locking portion 171, so as to avoid breakage due to excessive stress concentration when the first locking structure 511 and the corresponding first locking portion 151 and the second locking structure 522 and the corresponding second locking portion 171 are engaged and fixed with each other.

[0035] The specific structures of the first locking portion 151, the second locking portion 171, the first engaging structure 511 and the second engaging structure 522 of the present invention are not limited here, as long as the first locking portion 151 and the first engaging structure 511 are stably engaged, and the second locking portion 171 and the second engaging structure 522 are stably engaged.

[0036] In summary, the battery holder of the utility model has the following beneficial effects:

[0037] (1) The two first engaging structures 511 are respectively correspondingly engaged with the two first locking portions 151, and the two second engaging structures 522 are respectively correspondingly engaged with the two second locking portions 171. The arrangement of multiple engaging structures increases the holding force between the cover 5 and the base 1, meets the torque requirement of the battery holder safety regulations, and makes it difficult for children to separate the cover 5 from the base 1; the two second locking portions 171 are respectively correspondingly located on the outside of the two first locking portions 151, and the two second engaging structures 522 are respectively correspondingly located on the outside of the two first engaging structures 511. When the cover 5 is relative to the base 1, During rotation, the first engaging structure 511 and the second engaging structure 522 of the cover body 5 jointly clamp the base body 1 to prevent the cover body 5 from shifting toward one side, ensuring that the two first engaging structures 511 and the two first locking parts 151 are correspondingly fastened in place, and the two second engaging structures 522 and the two second locking parts 171 are correspondingly fastened in place, preventing the cover body 5 from shifting due to the shift of the center of gravity during rotation, resulting in the cover body 5 and the base body 1 not being able to achieve a fastening effect or the fastening failing, ensuring that the cover body 5 and the base body 1 have a good fastening effect and ensuring the structural stability of the battery holder.

[0038] (2) When viewed from top to bottom, the projections of the two first engaging structures 511 and the projections of the two second engaging structures 522 are located on the same straight line, and the projections of the first locking portion 151 and the second locking portion 171 located on the same side of the mounting portion 14 are aligned, which facilitates molding and saves space, so that there is enough space between the cover body 5 and the base body 1 to ensure that the cover body 5 can be rotated 90 degrees relative to the base body 1, and at the same time, it can prevent the cover body 5 from being offset during installation.

[0039] (3) Two first through slots 16 are provided on both sides of each first locking portion 151, and two second through slots 18 are provided on both sides of each second locking portion 171, which is conducive to the elastic deformation of the first locking portion 151 and the second locking portion 171 of the seat body 1, and prevents the first locking portion 151 and the second locking portion 171 from being worn too quickly or even broken due to strong extrusion when they are correspondingly locked with the first engaging structure 511 and the second engaging structure 522. There is a gap between the two side edges of the first engaging structure 511 and the two side edges of the corresponding giving way groove 512, and the two second engaging structures 522 are respectively provided on the inner side surfaces of the two thin portions 521, which is also conducive to enhancing the elasticity of the first engaging structure 511 and the second engaging structure 522 and improving their service life.

[0040] (4) The bottom surfaces of the two first slide grooves 15 stop the first engaging structure 511 from moving downward, so that there is a gap between the bottom surface of the main body 51 and the top surface of the battery D, preventing the main body 51 from pressing the battery D downward and then pressing the negative electrode spring sheet 3 to cause elastic fatigue of the negative electrode spring sheet 3. The top surfaces of the two second slide grooves 17 jointly stop the second engaging structure 522 from moving upward, ensuring that the cover body 5 will not separate from the base body 1 upward during the rotation process.

[0041] (5) The wall thickness portions of the first side wall 11 and the second side wall 12 provided with the first locking portion 151 respectively enter into the gaps between the two first engaging structures 511 and the corresponding second engaging structures 522 to make way for the portions of the first side wall 11 and the second side wall 12 provided with the first locking portion 151. At the same time, the first engaging structure 511 and the corresponding second engaging structure 522 jointly clamp the portions to prevent the cover body 5 from being displaced. The portions of the first side wall 11 and the second side wall 12 provided with the first locking portion 151 are respectively exposed in the two making way grooves 512 to facilitate observation of the fixing conditions of the two first engaging structures 511 and the corresponding first locking portions 151.

[0042] (6) The outer surface of each first locking portion 151 is covered with a metal sheet to prevent the first locking portion 151 from being squeezed and worn, thereby preventing insulating debris from falling into the receiving cavity 13.

[0043] (7) To separate the battery D from the base 1, each first engaging structure 511 must first be disengaged from the corresponding first locking portion 151, and each second engaging structure 522 must first be disengaged from the corresponding second locking portion 171. Then, the cover 5 must be driven to rotate 90 degrees and then lifted upward to separate the cover 5 from the base 1 before the battery D can be removed. The step-by-step operation prevents children from easily removing the battery D, thereby preventing them from accidentally swallowing the battery D.

[0044] 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. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
