[0037] [Specific implementation method]

[0038] In order to facilitate a better understanding of the purpose, structure, characteristics and effects of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods.

[0039] See also Figure 1 , Figure 2 , Fig.10 and Fig.14 The battery holder 100 of the present invention is used to accommodate a battery 5, and includes a seat body 1, a positive electrode spring 3 and a negative electrode spring 4 respectively accommodated in the seat body 1 and electrically connected to the battery 5, and a cover body 2, which is covered on the seat body 1 to cover the battery 5.

[0040] like Figures 1 to 8The first embodiment of the present invention is shown in FIG. 1 . The base 1 is made of insulating material. The base 1 has a bottom wall 11 and a wall 12 extending upward from the edge of the bottom wall 11. The bottom wall 11 and the wall 12 are together formed to form a receiving groove 13 for receiving the battery 5. The wall 12 covers most of the side surface of the battery 5. A slot 121 is provided through one side of the wall 12. After the cover 2 is separated from the base 1, the battery 5 can be directly removed by inserting a finger into the slot 121 without the need for special tools, which is conducive to the convenience of removing the battery 5. The base 1 is provided with a buckle portion 141 on opposite sides of the slot 121. Specifically, the base 1 is provided with a mounting portion 14 protruding outward on both sides of the slot 121. The two mounting portions 14 are provided with a buckle portion 141 on one side edge away from the slot 121 to buckle with the cover 2 to fix the cover 2 to the base 1 along the up and down direction. The upper surface of each snap portion 141 is flush with the upper surface of the corresponding mounting portion 14, and two clearance notches 122 are recessed downward from the upper surface of the wall 12 adjacent to the slot 121. In the left-right direction, the two clearance notches 122 are respectively located on both sides of the slot 121 and are connected to the slot 121. A positioning block 15 is provided on the other side of the base body 1 relative to the slot 121, and a rotating shaft 16 is protruded along the left-right direction on both sides of the positioning block 15. In the left-right direction, the two rotating shafts 16 are respectively located on both sides of the positive electrode spring sheet 3. A plurality of stopping portions 123 are protruded from the inner wall surface of the wall 12 to stop the upper surface of the battery 5, wherein the stopping area of ​​the stopping portion 123 close to the positive electrode spring sheet 3 is larger than the stopping area of ​​the stopping portion 123 close to the negative electrode spring sheet 4. As shown in FIG. Figure 1 , Figure 2 and Figure 5 As shown, the positive spring piece 3 and the negative spring piece 4 each have a fixing portion 32, 42 fixedly mounted on the seat body 1, a contact portion 31, 41 extending from one side of the fixing portion 32, 42 into the receiving groove 13 to be electrically connected to the battery 5, and a welding portion 33, 43 extending from the other side of the fixing portion 32, 42 out of the receiving groove 13 to be electrically connected to a circuit board (not shown), and the two mounting portions 14 are respectively recessed with a holding groove 143 on one side close to the slot 121, and the two sides of the fixing portion 42 of the negative spring piece 4 are respectively fixedly mounted. It is installed in two retaining grooves 143, and the middle part of the fixing part 42 of the negative spring sheet 4 is located in the slot 121, the positive spring sheet 3 is installed on the side of the base body 1 away from the slot 121, and the positive spring sheet 3 is located below the positioning block 15, the contact part 31 of the positive spring sheet 3 and the contact part 41 of the negative spring sheet 4 both elastically press the battery 5 upward, the contact part 31 of the positive spring sheet 3 is higher than the contact part 41 of the negative spring sheet 4, the contact part 31 of the positive spring sheet 3 presses against the side surface of the battery 5, and the contact part 41 of the negative spring sheet 4 presses against the lower surface of the battery 5.

[0041] like Figures 1 to 3As shown, the cover 2 is made of insulating material. In other embodiments, the cover 2 can also be made of metal. The cover 2 has a base plate 21. A limiting structure extends from one side of the base plate 21 and can be detachably assembled on the base 1. Specifically, in this embodiment, a limiting groove 211 is concavely provided on one side of the base plate 21. A rotating part 212 is convexly provided on both sides of the limiting groove 211. In this embodiment, the two rotating parts 212 are semi-arc-shaped to facilitate the disassembly of the cover 2. Figure 3 and Figure 6 As shown, when the operating cover 2 is rotated downward along the rotating shaft 16 of the base 1 and covered on the top of the base 1, the rotating part 212 rotates to the bottom of the rotating shaft 16, and the rotating shaft 16 stops the rotating part 212 of the cover 2 from moving upward. The limiting groove 211 of the cover 2 cooperates with the positioning block 15 of the base 1 to limit the cover 2 in the left and right directions, that is, the limiting structure plays a limiting role to limit one side of the cover 2 to one side of the base 1, and the stopping part 123 closest to the rotating shaft 16 is close to the positive spring piece 3 and is located above the contact part 31 of the positive spring piece 3, and the stopping part 123 closest to the rotating shaft 16 presses downward against the battery 5, ensuring that the battery 5 is in full elastic contact with the contact part 31 of the positive spring piece 3. When the cover 2 needs to be removed, the cover 2 is lifted up to the open state, the rotating portion 212 rotates to the top of the rotating shaft 16, and the positioning block 15 is separated from the limiting groove 211. At this time, the rotating portion 212 is not restricted, and the limiting structure and the base 1 can be removed and separated.

[0042] like Figures 4 to 8As shown, two elastic arms 22 extending in the front-to-back direction and an additional portion 24 located between the two elastic arms 22 are provided from the other side of the base portion 21 relative to the limiting structure, and a locking section 23 extends downward from the side of each elastic arm 22 away from the base portion 21. The base portion 21 and the additional portion 24 are both provided with a plurality of heat dissipation holes 25 penetrating in the up-down direction for heat dissipation. The battery 5 is exposed in the plurality of heat dissipation holes 25. The diameter of each heat dissipation hole 25 is smaller than the minimum distance between the two elastic arms 22. Therefore, the heat dissipation hole 25 has a smaller size to prevent children from inserting their fingers into the heat dissipation hole 25. The lower surfaces of the base portion 21 and the additional portion 24 are both provided with a plurality of reinforcing ribs 26 to strengthen the strength of the base portion 21 and the additional portion 24. There is a gap between the lower surface of each reinforcing rib 26 and the upper surface of the battery 5 to prevent other reinforcing ribs 26 from being stuck when the cover 2 is covered on the base 1. 6 interferes with the battery 5, resulting in the locking section 23 of the cover 2 being unable to be snap-fastened with the base 1; the two reinforcing ribs 26 closest to the locking section 23 are further provided with a protrusion 27 in the up-down direction, and the two protrusions 27 contact the upper surface of the battery 5 to prevent the battery holder 100 from shaking in the receiving slot 13 under a vibration environment, and when the upper surface of the cover 2 is impacted by an external force, the impact force can be released to the battery 5 through the two protrusions 27, and the impact force is further released to the bottom wall 11 of the base 1 through the battery 5, and finally transferred to the circuit board, thereby preventing the cover 2 from being damaged. Each elastic arm 22 is provided with an operating portion 221 and a through hole 222 that penetrates the operating portion 221 in the up-down direction on the side away from the base portion 21, so that the two elastic arms 22 are offset in a direction close to each other by applying an external force through the two operating portions 221. The two elastic arms 22 respectively pass through the corresponding clearance notches 122 and are partially located on the upper side of the mounting portion 14. The two clearance notches 122 make way for the two elastic arms 22, thereby reducing the height of the battery holder 100. After the cover 2 is installed in place, the upper surface of the cover 2 is not higher than the top surface of the seat 1, so the cover 2 does not increase the height of the battery holder 100, which is conducive to the miniaturization of the battery holder 100. The upper surfaces of the two mounting portions 14 support the lower surfaces of the two elastic arms 22, so that the two locking segments 23 are correspondingly buckled with the two buckle portions 141. Each locking segment 23 includes an extension portion 231 extending downward from the corresponding elastic arm 22 and a retaining portion 232 provided on the extension portion 231 to be fixedly secured with the corresponding retaining portion 141. In the present embodiment, the two retaining portions 232 are configured as recessed grooves formed from the inner side surfaces of the two extension portions 231, and the two retaining portions 141 are configured as retaining blocks formed by protruding from the edge of one side of the two mounting portions 14 away from the groove 121. In other embodiments, the two retaining portions 232 can also be configured as retaining blocks, and the two retaining portions 141 can be configured as retaining grooves, as long as the two retaining portions 141 and the two retaining portions 232 can be fixedly secured by retaining up and down.

[0043] like Figure 3and Figures 5 to 7 As shown, in this embodiment, since the buckle portion 141 is a block structure, when the cover body 2 is assembled in place, each block is aligned with each through hole 222 in the up and down direction, so that each block is exposed in the corresponding through hole 222 in the up and down direction, which makes it easy to observe the buckle condition of the block and the slot through the through hole 222. The upper ends of the two buckle portions 141 on one side facing each other are provided with a first inclined surface 142 inclined downwardly, and each holding portion 232 is formed by being recessed downwardly from the upper end of the inner side surface of each extension portion 231. The lower ends of the two locking segments 23 on the side away from each other are respectively provided with a second inclined surface 233 inclined upwardly. In this embodiment, the second inclined surface 233 is arranged at the lower end of the extension portion 231, and the second inclined surface 233 is located below the holding portion 232. The first inclined surface 142 and the second inclined surface 233 cooperate with each other to jointly guide the two extension portions 231 to move downward, so that the two holding portions 232 deviate in a direction close to each other and simultaneously snap into the two buckle portions 141 downwardly, so as to fix the cover body 2 to the base body 1 along the up and down direction.

[0044] like Figures 5 to 8As shown, the additional portion 24 includes a first section 241 extending from the substrate portion 21 in the front-to-back direction and spaced apart from the two elastic arms 22, and a second section 242 extending downward from the first section 241 away from the substrate portion 21. The width of the first section 241 of the additional portion 2 is greater than the width of the two elastic arms 22. The first section 241, the substrate portion 21 and the two elastic arms 22 cover the upper surface of the battery 5 together, and the second section 242 enters the slot 121 and covers the side surface of the battery 5 exposed in the slot 121. The two elastic arms 22 of this embodiment are respectively located at the two side edges of the cover body 2, and the outer edges of the two elastic arms 22 are both arc-shaped to be close to the inner wall surface of the enclosure 12, so as to avoid the gap between the two elastic arms 22 and the enclosure 12 being too large to cause the fingers of children to be inserted, and the outer edges of the two elastic arms 22 do not exceed the outer side surface of the enclosure 12, thereby ensuring the miniaturization of the battery holder 100. The width of the first section 241 of the additional portion 24 in the extension direction of the elastic arm 22 gradually decreases, so that the distance between the first section 241 and each elastic arm 22 is always smaller than the width of a child's finger, and the distance between the second section 242 and the two locking sections 23 is smaller than the width of each locking section 23, that is, the distance between the second section 242 and the two locking sections 23 is much smaller than the width of a child's finger, and the distance between the first section 241 and the two elastic arms 22 is also smaller than the width of a child's finger, so that it is difficult for children to find the battery 5, and the child's fingers cannot be inserted into the receiving groove 13, preventing the child from easily taking out the battery 5 from the top of the receiving groove 13 or from the slot 121 into the receiving groove 13, and preventing the child from accidentally swallowing the battery 5. The part of the second section 242 close to the battery 5 is used to shield the side surface of the battery 5, and the other part of the second section 242 is located between the two locking sections 23 to prevent the two locking sections 23 from excessively shifting toward each other; the minimum lateral width of the part of the second section 242 close to the battery 5 is greater than or equal to the lateral width of the other part of the second section 242, so that the part of the second section 242 close to the battery 5 can fully shield the side surface of the battery 5, and the other part of the second section 242 is used to reserve space for the two locking sections 23 to shift toward each other, playing a role of giving way. The second section 242 forms a guide arc surface 2421 on the side facing the battery 5, and the guide arc surface 2421 guides the second section 242 to pass over the battery 5 from above the battery 5 and enter the slot 121, preventing the second section 242 from colliding with the battery 5. The upper surface of the first section 241 is flush with the upper surface of each elastic arm 22, and the lower surface of the second section 242 is flush with the lower surface of each locking section 23 or extends downward beyond the lower surface of each locking section 23, ensuring that the second section 242 can completely block the two locking sections 23 from excessively deviating toward each other; the negative electrode spring sheet 4 is located below the second section 242, and in the up and down directions, there is a gap between the lower surface of the second section 242 and the negative electrode spring sheet 4, preventing the second section 242 from contacting and colliding with the negative electrode spring sheet 4.In this embodiment, the additional portion 24 shields the side surface of the battery 5 exposed in the groove 121, and the mounting portion 14 and the wall 12 shield the remaining portion of the side surface of the battery 5. In other embodiments, the additional portion 24 and the locking segment 23 can simultaneously shield the side surface of the battery 5 exposed in the groove 121, as long as a good shielding effect is guaranteed.

[0045] See also Figure 1 , Figure 2 and Figure 7 When the battery 5 needs to be taken out, the two operating parts 221 of the cover body 2 need to be pressed in the left and right directions first, so that the two elastic arms 22 of the cover body 2 move toward each other, and the two buckling parts 232 move toward each other and disengage from the two buckling parts 141 of the base body 1, and then the cover body 2 is operated to rotate the two rotating parts 212 along the two rotating shafts 16 of the base body 1, so that the side of the cover body 2 provided with the two elastic arms 22 is lifted upward, and then the cover body 2 is lifted upward to separate the two rotating parts 212 of the cover body 2 from the two rotating shafts 16 of the base body 1, and then the cover body 2 is separated from the base body 1. The two-step operation of first pressing the two locking sections 23 to disengage the two buckling parts 232 from the two buckling parts 141 of the base body 1 and then lifting the cover body 2 to separate the two rotating parts 212 of the cover body 2 from the two rotating shafts 16 of the base body 1 makes it difficult for children to take out the battery 5 easily, thereby preventing children from accidentally swallowing the battery 5.

[0046] like Figures 9 to 12The figure shows a battery holder 100 of the second embodiment of the present invention. The cover 2 of the second embodiment is not pivotally connected to the seat 1, but is installed to the seat 1 by oblique insertion, and the appearance of the two elastic arms 22' of the cover 2 is different from that of the elastic arms 22 of the first embodiment. Specifically, the two elastic arms 22' extend horizontally from the middle of the base plate 21, and the thickness of the operating portion 221' on each elastic arm 22' in the up-down direction is greater than the thickness of other positions of the elastic arm 22', and the operating portion 221' is also penetrated by a through hole 222' in the up-down direction. The two elastic arms 22' are arranged in parallel, and the additional portion 24' is located between the two elastic arms 22'. The inner wall surface of one side of the enclosure 12 having the slot 121 is protruded with a plurality of stoppers 123 in the horizontal direction. The negative electrode spring sheet 4 is mounted on the bottom wall 11 of the base body 1. The positive electrode spring sheet 3 is mounted on the side of the enclosure 12 away from the slot 121. The contact portion 31 of the positive electrode spring sheet 3 is located on the upper side of the battery 5 to electrically contact the upper surface of the battery 5. The contact portion 31 of the positive electrode spring sheet 3 and the stopper 123 are respectively located on opposite sides of the top of the battery 5 to jointly stop the battery 5. Two engaging grooves F are penetrated on the other side of the wall 12 relative to the slot 121. In the horizontal direction, the two engaging grooves F are respectively located on both sides of the positive spring sheet 3. The base plate portion 21 is provided with a spring-shaped abutting portion G protruding downward. The two contact portions 31 of the positive spring sheet 3 are respectively located on the two outer sides of the extension line of the two side edges of the abutting portion G. The abutting portion G extends downward to abut the battery 5 to prevent the battery 5 from shaking in the receiving groove 13. The limiting structure includes two limit blocks H protruding from one side of the base plate portion 21 of the cover body 2 at intervals. The side of the cover body 2 provided with the limit blocks H is obliquely inserted toward the positive spring sheet 3 of the seat body 1, so as to insert the two limit blocks H of the cover body 2 into the two engaging grooves F of the seat body 1, thereby limiting the displacement of the side of the cover body 2 provided with the limit blocks H in the horizontal direction. The two snap-fitting portions 141 are respectively formed as a slot recessed from one side of the two mounting portions 14 facing each other, and the two mounting portions 14 are provided with a first inclined surface 142 inclined downward from the upper end on one side facing each other, and the two first inclined surfaces 142 are both located above the slot, and the two holding portions 232' are formed as a block protruding from one side of the two extending portions 231' away from each other, and the two locking segments 23' are provided with a second inclined surface 233' inclined upward from the lower end on one side away from each other. In this embodiment, the second inclined surface 233' is arranged at the lower end of the snap-fitting portion 232', and the first inclined surface 142 and the second inclined surface 233' cooperate to jointly guide the two locking segments 23' to move downward, so that the two locking segments 23' are respectively fixed to the two snap-fitting portions 141 in a direction away from each other.The first section 241' located between the two operating parts 221' blocks the two elastic arms 22' from excessively deviating in the direction of approaching each other. The second section 242' and the two locking sections 23' are both located in the slot 121. The distance between the first section 241' and the two elastic arms 22' is less than or equal to the distance between the second section 242' and the two locking sections 23'. The distance between the second section 242' and the two locking sections 23' is less than the width of a child's finger. The upper surface of the battery 5 is jointly shielded by the base plate portion 21 and the two elastic arms 22'. The side surface of the battery 5 exposed in the slot 121 can be jointly shielded by the additional portion 24' and the two locking sections 23', so that children are not easy to find the battery 5, and children's fingers cannot be inserted into the receiving slot 13, preventing children from easily taking out the battery 5 by inserting their fingers into the receiving slot 13 from the top of the receiving slot 13 or from the slot 121.

[0047] When the battery 5 needs to be removed, the two holding portions 232' are first disengaged from the two snap-fit ​​portions 141, and then the side of the cover body 2 provided with the two elastic arms 22' is lifted upwards to make the two elastic arms 22' of the cover body 2 exit the slots 121 of the base body 1, and then the cover body 2 is tilted and pulled out to make the two limit blocks H of the cover body 2 exit the two snap-fitting slots F of the base body 1, thereby separating the cover body 2 from the base body 1.

[0048] like Figures 13 to 16As shown, the battery holder 100 of the third embodiment of the present invention is different from the second embodiment in that: there are multiple additional parts 24", and the multiple additional parts 24" are respectively protruded in the horizontal direction from the side where the two elastic arms 22" are close to each other, and the projection of one additional part 24" in the horizontal direction overlaps with the projection of the operating part 221". The multiple additional parts 24" can strengthen the strength of the two elastic arms 22", so that the two elastic arms 22" are not easy to break. Each additional part 24" is staggered with other additional parts 24" in the extension direction of the elastic arm 22". The multiple additional parts 24" fill the gap between the two elastic arms 22" to prevent children's fingers from extending into the receiving groove 13, and the multiple additional parts 24" are used to block the different positions of the side edges of the elastic arms 22" adjacent to them, which can better prevent the two elastic arms 22" from excessively deviating in the direction of approaching each other. The two locking segments 23" are both located in the slot 121. The two holding portions 232", the two extension portions 231" and the side of the two locking segments 23" away from each other are all provided with a second inclined surface 233" inclined upward from the lower end. They are the same as the second embodiment, and can also play the role of guiding the two locking segments 23" to move downward through the cooperation of the first inclined surface 142 and the second inclined surface 233", so that the two locking segments 23" are respectively locked and fixed with the two locking portions 141 in the direction away from each other. The multiple additional portions 24" jointly prevent the two elastic arms 22" from excessively deviating in the direction of approaching each other. The two locking segments 23" are located in the slot 121 to shield the side surface of the battery 5, and the distance between the two locking segments 23" is less than the width of a child's finger, so that the child is not easy to find the battery 5, and the child's finger cannot be inserted into the receiving slot 13, preventing the child from easily taking out the battery 5 from the top of the receiving slot 13 or from the slot 121 into the receiving slot 13.

[0049] When the battery 5 needs to be removed, first disengage the two retaining portions 232" from the two snap-fit ​​portions 141 accordingly, then lift up the side of the cover body 2 provided with the two elastic arms 22", so that the two elastic arms 22" of the cover body 2 exit the slots 121 of the base body 1, then tilt the cover body 2 out so that the two limit blocks H of the cover body 2 exit the two snap-fit ​​slots F of the base body 1, thereby separating the cover body 2 from the base body 1.

[0050] In summary, the battery holder 100 of the present invention has the following beneficial effects:

[0051] (1) The two locking segments 23 are offset in a direction of approaching each other and are simultaneously locked downwardly into the two locking portions 141, thereby limiting the movement of the cover body 2 relative to the base body 1 in the vertical direction; the additional portion 24 is located between the two elastic arms 22, thereby preventing the two elastic arms 22 from excessively offset in a direction of approaching each other due to uneven force, thereby preventing the locking segments 23 from being unable to be locked into the corresponding locking portions 141, thereby ensuring that the two locking segments 23 can be locked and fixed with the two locking portions 141 at the same time, so that the cover body 2 can be firmly fixed to the base body 1; the limiting structure of the cover body 2 and the locking segments 23 of the cover body 2 are together The cover body 2 is fixed to the base body 1 to ensure the firmness and stability of the battery holder 100 structure; the wall 12 covers most of the side surface of the battery 5, and the base plate portion 21 and the two elastic arms 22 of the cover body 2 jointly cover the upper surface of the battery 5. Even in the case of long-term vibration, the cover body 2 can stop the battery 5 from falling off the receiving groove 13. The additional portion 24 covers the side surface of the battery 5 exposed in the groove 121, making it difficult for children to find the battery 5, preventing children from reaching into the receiving groove 13 from the top of the receiving groove 13 or from the groove 121 to take out the battery 5, and preventing children from accidentally swallowing the battery 5.

[0052] (2) The first section 241, the base plate 21 and the two elastic arms 22 cover the upper surface of the battery 5 together, and the second section 242 enters the slot 121 and covers the side surface of the battery 5 exposed in the slot 121; the two elastic arms 22 are respectively located at the two side edges of the cover body 2, and the outer edges of the two elastic arms 22 are both arc-shaped to be close to the inner wall surface of the enclosure 12, so as to avoid the gap between the two elastic arms 22 and the enclosure 12 being too large to cause children's fingers to enter, and the outer edges of the two elastic arms 22 do not exceed the outer side surface of the enclosure 12, thereby ensuring The volume of the battery holder 100 is miniaturized; the width of the first section 241 in the extension direction of the elastic arm 22 gradually decreases, so that the distance between the first section 241 and each elastic arm 22 is always smaller than the width of a child's finger, and the distance between the second section 242 and the two locking sections 23 is smaller than the width of each locking section 23, making it difficult for children to find the battery 5, and the children's fingers cannot be inserted into the receiving groove 13, preventing children from easily taking out the battery 5 from the top of the receiving groove 13 or from the slot 121 into the receiving groove 13, and preventing children from accidentally swallowing the battery 5.

[0053] (3) The portion of the second section 242 close to the battery 5 is used to shield the side surface of the battery 5, and the other portion of the second section 242 is located between the two locking sections 23 to prevent the two locking sections 23 from excessively shifting toward each other; the minimum lateral width of the portion of the second section 242 close to the battery 5 is greater than or equal to the lateral width of the other portion of the second section 242, so that the portion of the second section 242 close to the battery 5 can fully shield the side surface of the battery 5, and the other portion of the second section 242 reserves space for the two locking sections 23 to shift toward each other, playing a role of giving way. The second section 242 forms a guide arc surface 2421 on the side facing the battery 5, and the guide arc surface 2421 guides the second section 242 to pass over the battery 5 from above the battery 5 and enter the slot 121, preventing the second section 242 from colliding with the battery 5.

[0054] (4) The upper surface of the first section 241 is flush with the upper surface of each elastic arm 22, and the lower surface of the second section 242 is flush with the lower surface of each locking section 23 or extends downward beyond the lower surface of each locking section 23, ensuring that the second section 242 can completely block the two locking sections 23 from excessively deviating toward each other; the negative electrode spring sheet 4 is located below the second section 242, and there is a gap between the lower surface of the second section 242 and the negative electrode spring sheet 4 in the up and down direction, preventing the second section 242 from contacting and colliding with the negative electrode spring sheet 4.

[0055] (5) The base plate 21 and the additional portion 24 are both provided with a plurality of heat dissipation holes 25 in the vertical direction to facilitate heat dissipation. The lower surfaces of the base plate 21 and the additional portion 24 are both provided with a plurality of reinforcing ribs 26 to strengthen the strength of the base plate 21 and the additional portion 24. There is a gap between the lower surface of each reinforcing rib 26 and the upper surface of the battery 5 to prevent other reinforcing ribs 26 from interfering with the battery 5 when the cover 2 is covered on the base 1, thereby preventing the locking section 23 of the cover 2 from being unable to be snap-fitted with the base 1. The two reinforcing ribs 26 closest to the locking section 23 are both further provided with a protrusion 27 in the vertical direction. The two protrusions 27 contact the upper surface of the battery 5 to prevent the battery holder 100 from shaking in the receiving groove 13 under a vibration environment. When the upper surface of the cover 2 is impacted by external force, the impact force can be released to the battery 5 through the two protrusions 27, and the impact force is further released to the bottom wall 11 of the base 1 through the battery 5, and finally the impact force is transferred to the circuit board, thereby preventing the cover 2 from being damaged.

[0056] (6) The cover 2 and the base 1 can be separated by first pressing the two locking sections 23 to disengage the two retaining portions 232 from the two snap portions 141 of the base 1, and then lifting the cover 2 to separate the two rotating portions 212 of the cover 2 from the two rotating shafts 16 of the base 1, or tilting the cover 2 to make the two limit blocks H of the cover 2 withdraw from the two snap-fit ​​grooves F of the base 1. The step-by-step operation prevents children from easily removing the battery 5, thereby preventing children from accidentally swallowing the battery 5. When it is necessary to remove the battery 5, the battery 5 can be directly removed from the slot 121 with fingers only after the cover 2 and the base 1 are separated.

[0057] The above detailed description is only an explanation of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
