Description

Technical field

[0001] The utility model relates to a battery holder, in particular to a battery holder with a cover. [Background Technology]

[0002] It is a very common phenomenon that batteries are used as power sources for a variety of electrical devices, and children also come into contact with a variety of electrical devices in their daily lives. A battery holder currently used for an electrical device includes a base and a battery. The bottom wall of the base and the side walls extending upward from the edge of the bottom wall together form a receiving slot to accommodate the battery. A slot is formed through one side of the wall to facilitate the hand to reach into the receiving slot through the slot to remove the battery, without the need for special tools, making it easy to disassemble and replace the battery. The upper surface and part of the side surface of the battery are exposed. In order to fix the battery, multiple protrusions are usually provided on the inner wall surfaces on opposite sides of the wall. The multiple protrusions are all located on the upper edge side of the battery to prevent the battery from moving upward and falling out of the receiving slot. However, such a structure makes the upper surface and the side surface of the battery exposed on the base, making it easy for children to find the battery and directly insert their fingers into the receiving slot to remove the battery, which may cause children to accidentally swallow the battery. There is also a risk that the battery is easily dropped out of the receiving slot in a long-term vibration environment.

[0003] Therefore, it is necessary to design an improved battery holder to solve the above technical problems. [Utility Model Content]

[0038]

[0039] [Specific implementation method]

[0040] In order to facilitate a better understanding of the purpose, structure, features and effects of the present invention, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods.

[0041] See also Figure 1 、 Figure 2 、 Figure 10 and Figure 14 The battery holder 100 of the present invention is used to accommodate a battery 5, and includes a base body 1, a positive spring 3 and a negative spring 4 respectively accommodated in the base body 1 and electrically connected to the battery 5, and a cover body 2, which is covered on the base body 1 to cover the battery 5.

[0042] like Figures 1 to 8 The figure shows a first embodiment of the present invention. The base 1 is made of an insulating material and 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 together form a receiving slot 13 for accommodating the battery 5. The wall 12 shields most of the side surface of the battery 5. A slot 121 is provided on one side of the wall 12. After the cover 2 is separated from the base 1, the battery 5 can be removed directly by inserting a finger into the slot 121, without the need for special tools, which facilitates the removal of the battery 5. The base 1 has a locking portion 141 on opposite sides of the slot 121. Specifically, the base 1 has a mounting portion 14 protruding outwardly on each side of the slot 121. The two mounting portions 14 are each provided with a locking portion 141 on one edge of the side away from the slot 121 to engage with the cover 2 to secure the cover 2 to the base 1 in the vertical 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 formed downwardly from the upper surface of the wall 12 adjacent to the slot 121. In the left and right directions, 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 and right directions on both sides of the positioning block 15. In the left and right directions, the two rotating shafts 16 are respectively located on both sides of the positive spring piece 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 spring piece 3 is larger than the stopping area of ​​the stopping portion 123 close to the negative spring piece 4. As shown Figure 1 、 Figure 2 and Figure 5As shown, the positive spring piece 3 has a first fixing portion 32 fixedly mounted on the base 1, a first contact portion 31 extending from one side of the first fixing portion 32 into the receiving groove 13 to be electrically connected to the battery 5, and a first welding portion 33 extending from the other side of the first fixing portion 32 out of the receiving groove 13 to be electrically connected to a circuit board (not shown), and the negative spring piece 4 has a second fixing portion 42 fixedly mounted on the base 1, a second contact portion 41 extending from one side of the second fixing portion 42 into the receiving groove 13 to be electrically connected to the battery 5, and a second welding portion 43 extending from the other side of the second fixing portion 42 out of the receiving groove 13 to be electrically connected to the circuit board, and the two mounting portions 14 are close to the slot. A retaining groove 143 is recessed on one side of 121, and both sides of the second fixing portion 42 of the negative spring clip 4 are respectively retained and installed in the two retaining grooves 143, and the middle part of the second fixing portion 42 of the negative spring clip 4 is located in the slot 121. The positive spring clip 3 is installed on the side of the base body 1 away from the slot 121, and the positive spring clip 3 is located below the positioning block 15. The first contact portion 31 of the positive spring clip 3 and the second contact portion 41 of the negative spring clip 4 both elastically press against the battery 5 upward, and the first contact portion 31 of the positive spring clip 3 is higher than the second contact portion 41 of the negative spring clip 4. The first contact portion 31 of the positive spring clip 3 presses against the side surface of the battery 5, and the second contact portion 41 of the negative spring clip 4 presses against the lower surface of the battery 5.

[0043] like Figures 1 to 3 As 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 to the base 1. Specifically, in this embodiment, a limiting groove 211 is recessed on one side of the base plate 21. A rotating portion 212 is protruded from both sides of the limiting groove 211. In this embodiment, the two rotating portions 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 first contact part 31 of the positive spring piece 3, and the stopping part 123 closest to the rotating shaft 16 presses the battery 5 downward, ensuring that the battery 5 is in full elastic contact with the first 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 disengages from the limiting groove 211. At this time, the rotating portion 212 is not restricted, and the limiting structure can be detached from the base 1.

[0044] like Figures 4 to 8 As 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 on the other side of the base portion 21 relative to the limiting structure. A locking section 23 extends downward from the side of each elastic arm 22 away from the base portion 21. Both the base portion 21 and the additional portion 24 are provided with a plurality of heat dissipation holes 25 extending in the up-down direction to facilitate 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 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 inserted when the cover 2 is placed on the base 1. 6 interferes with the battery 5, causing the locking section 23 of the cover 2 to be unable to be locked with the base 1; the two reinforcing ribs 26 closest to the locking section 23 are each further provided with a protrusion 27 in the vertical direction. Both protrusions 27 contact the upper surface of the battery 5, preventing the battery 5 from shaking within the receiving slot 13 when the battery holder 100 is subjected to vibration. 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 transferred to the circuit board, thereby preventing the cover 2 from being damaged. Each elastic arm 22 is provided with an operating portion 221 on the side away from the base portion 21 and a through hole 222 extending vertically through the operating portion 221, so that external force can be applied through the two operating portions 221 to cause the two elastic arms 22 to deflect toward each other. The two elastic arms 22 pass through 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 lowering the height of the battery holder 100. When the cover 2 is installed, the upper surface of the cover 2 is no higher than the top surface of the base 1. Therefore, the cover 2 does not increase the height of the battery holder 100, which facilitates 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, facilitating the corresponding locking segments 23 and the two locking portions 141. Each locking section 23 includes an extension portion 231 extending downward from the corresponding elastic arm 22 and a holding portion 232 provided on the extension portion 231 to be fastened with the corresponding latch portion 141. In the present embodiment, the two holding portions 232 are configured as slots formed by recessed recesses on the inner side surfaces of the two extension portions 231, and the two latch portions 141 are configured as blocks protruding from one side edge of the two mounting portions 14 away from the slot 121. In other embodiments, the two holding portions 232 can also be configured as blocks and the two latch portions 141 can be configured as slots, as long as the two latch portions 141 and the two holding portions 232 can be fastened up and down.

[0045] like Figure 3 and Figures 5 to 7 As shown, in this embodiment, since the snap-fit ​​portion 141 is a snap-fitting structure, when the cover body 2 is assembled in place, each snap-fitting block is aligned with each through hole 222 in the up and down directions, so that each snap-fitting block is exposed in the corresponding through hole 222 in the up and down directions, making it easy to observe the snap-fitting condition of the snap-fitting block and the slot through the through hole 222. The upper ends of the two latching portions 141 facing each other are provided with a first inclined surface 142 inclined downwardly. Each holding portion 232 is 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 away from each other are respectively provided with a second inclined surface 233 inclined upwardly. In this embodiment, the second inclined surface 233 is provided 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 engage with the two latching portions 141 downwardly to fix the cover body 2 to the base body 1 in the up and down directions.

[0046] like Figures 5 to 8As shown, the attachment portion 24 includes a first section 241 extending from the base 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 side of the first section 241 away from the base portion 21. The width of the first section 241 of the attachment portion 2 is greater than the width of the two elastic arms 22. The first section 241, the base portion 21, and the two elastic arms 22 collectively cover the upper surface of the battery 5. The second section 242 enters the slot 121 and shields the side surface of the battery 5 exposed in the slot 121. In this embodiment, the two elastic arms 22 are located on the two side edges of the cover 2. The outer edges of the two elastic arms 22 are curved to approach the inner wall surface of the enclosure 12, preventing the gap between the two elastic arms 22 and the enclosure 12 from being too large, which could allow children's fingers to enter. The outer edges of the two elastic arms 22 do not extend beyond the outer side surface of the enclosure 12, thereby ensuring the compact size 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, making it difficult for children to find the battery 5, and the child's fingers cannot be inserted into the receiving slot 13, preventing the child from easily removing the battery 5 from the top of the receiving slot 13 or from the slot 121 into the receiving slot 13, thereby preventing the child from accidentally swallowing the battery 5. The portion of the second segment 242 proximal to the battery 5 shields the side surface of the battery 5, while the other portion of the second segment 242 is located between the two locking segments 23 to prevent the two locking segments 23 from excessively deflecting toward each other. The minimum lateral width of the portion of the second segment 242 proximal to the battery 5 is greater than or equal to the lateral width of the other portion of the second segment 242, enabling the portion of the second segment 242 proximal to the battery 5 to fully shield the side surface of the battery 5. The other portion of the second segment 242 provides space for the two locking segments 23 to deflect toward each other, thus providing clearance. A guide arc 2421 is formed on the side of the second segment 242 facing the battery 5. The guide arc 2421 guides the second segment 242 from above the battery 5, past the battery 5, and into the slot 121, preventing the second segment 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 prevent the two locking sections 23 from excessively deviating toward each other; the negative electrode spring 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 4 in the vertical direction, preventing the second section 242 from contacting and colliding with the negative electrode spring 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 part 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 ensured.

[0047] See also Figure 1 、 Figure 2 and Figure 7 When the battery 5 needs to be removed, it is necessary to first press the two operating parts 221 of the cover body 2 in the left and right directions 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 snap parts 141 of the base body 1. Then, operate the cover body 2 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 with the two elastic arms 22 is lifted up, and then lift the cover body 2 upward to separate the two rotating parts 212 of the cover body 2 from the two rotating shafts 16 of the base body 1 before the cover body 2 can be 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 snap 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 remove the battery 5 easily, thereby preventing children from accidentally swallowing the battery 5.

[0048] like Figures 9 to 12The figure shows a battery holder 100 according to a second embodiment of the present invention. The cover 2 of the second embodiment is not pivotally connected to the base 1, but is instead installed thereto by oblique insertion. Furthermore, the shape of the two elastic arms 22' of the cover 2 differs from that of the elastic arms 22 of the first embodiment. Specifically, the two elastic arms 22' extend horizontally from the center of the base portion 21. The thickness of the operating portion 221' on each elastic arm 22' is greater than that of the other portions of the elastic arm 22' in the vertical direction. Furthermore, a through hole 222' is also formed through the operating portion 221' in the vertical direction. The two elastic arms 22' are arranged side by side, with the additional portion 24' located between the two elastic arms 22'. The inner wall surface of the side of the enclosure 12 where the slot 121 is provided has a plurality of stop portions 123 protruding in the horizontal direction. The negative electrode spring clip 4 is mounted on the bottom wall 11 of the base 1, and the positive electrode spring clip 3 is mounted on the side of the enclosure 12 away from the slot 121. The first contact portion 31 of the positive electrode spring clip 3 is located on the upper side of the battery 5 to electrically contact the upper surface of the battery 5. The first contact portion 31 of the positive electrode spring clip 3 and the stop portion 123 are respectively located on opposite sides of the top of the battery 5 to jointly stop the battery 5. Two snap-fitting grooves F are provided on the other side of the wall 12 relative to the slot 121. In the horizontal direction, the two snap-fitting grooves F are respectively located on both sides of the positive spring piece 3. The base plate portion 21 is provided with a spring-shaped abutting portion G protruding downward. The two first contact portions 31 of the positive spring piece 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 with the limit block H is inserted obliquely toward the positive spring piece 3 of the base body 1 to insert the two limit blocks H of the cover body 2 into the two snap-fitting grooves F of the base body 1, limiting the displacement of the side of the cover body 2 with the limit block 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. 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. The two first inclined surfaces 142 are both located above the slot. The two holding portions 232' are formed as a block protruding from one side of the two extension portions 231' away from each other. 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 provided at the lower end of the snap-fitting portion 232'. 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 portion of the first section 241' located between the two operating portions 221' blocks the two elastic arms 22' from excessively deviating toward 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, so that the upper surface of the battery 5 and the side surface of the battery 5 exposed in the slot 121 can be shielded, making it difficult for children to find the battery 5. The child's fingers cannot reach into the receiving slot 13, preventing the child from easily removing the battery 5 by reaching into the receiving slot 13 from the top of the receiving slot 13 or from the slot 121.

[0049] When the battery 5 needs to be removed, the two retaining portions 232' are first disengaged from the two snapping portions 141, and then the side of the cover 2 provided with the two elastic arms 22' is lifted upwards to allow the two elastic arms 22' of the cover 2 to exit the slots 121 of the base 1. The cover 2 is then tilted and pulled out to allow the two limit blocks H of the cover 2 to exit the two snapping slots F of the base 1, thereby separating the cover 2 from the base 1.

[0050] like Figures 13 to 18 As shown, the battery holder 100 of the third embodiment of the present invention is shown. The cover 2 is also installed obliquely on the base 1. The wall 12 is recessed with two engaging grooves F at intervals. Two limit blocks H extend from one side of the base portion of the cover 2. When assembling the cover 2, the two limit blocks H can be first inserted into the two engaging grooves F at an angle, and then placed horizontally in the two engaging grooves F. Figure 17 As shown, the top surface of the limit block H is blocked by the upper wall surface of the snap-fitting groove F, so that the side of the cover body 2 provided with the limit block H cannot escape upward from the base body 1, that is, the upper wall surface of the snap-fitting groove F blocks the side of the cover body 2 provided with the limit block H from moving upward, and the two sides of each limit block H are limited within the inner wall surface of the corresponding snap-fitting groove F, limiting the cover body 2 from moving left and right or rotating circumferentially, and the length of the snap-fitting groove F extending in the up and down directions is greater than the thickness of the limit block H in the up and down directions. When the cover body 2 is hit by external force, the snap-fitting groove F can allow the limit block H to move downward, and one end of the cover body 2 provided with the limit block H can abut against the upper surface of the battery 5 to transfer the impact force to the battery 5, and further transfer the impact force to the bottom wall 11 of the base body 1 through the battery 5, and finally transfer the impact force to the circuit board to prevent the cover body 2 from being damaged, so that the cover body 2 can withstand a larger impact force, avoiding the cover body 2 from breaking and causing the battery to be exposed.

[0051] like Figure 14As shown, the wall 12 has a first top surface 127 corresponding to the top of each snap-fitting groove F, and the upper surface of the mounting portion 14 is a second top surface 128, and the second top surface 128 is lower than the first top surface 127. The wall 12 is provided with two reinforcing portions 124 protruding outward above the two snap-fitting grooves F. The thickness of the wall 12 where the reinforcing portions 124 are provided along the wall thickness direction of the wall 12 is greater than the thickness of other parts of the wall 12, thereby strengthening the strength of the base 1. The upper surface of the reinforcing portion 124 is flush with the first top surface 127. The base 1 is provided with a terminal groove 125 between the two reinforcing portions 124 for accommodating the positive spring piece 3. The terminal groove 125 is connected to the receiving groove 13, and a protruding wall 126 is provided on the side of the terminal groove 125 away from the receiving groove 13, see Figure 10 The structures of the positive electrode spring piece 3 and the negative electrode spring piece 4 in this embodiment are the same as those of the positive electrode spring piece 3 and the negative electrode spring piece 4 in the second embodiment. Figure 16 The first fixing portion 32 of the positive spring piece 3 shown is snap-fitted and fixed to the protruding wall 126, and the positive spring piece 3 is bent and extended from its first fixing portion 32 into the terminal groove 125 to form a movable portion 34. The first fixing portion 32 and the movable portion 34 are connected in a U-shape. There is a gap between the movable portion 34 and the first fixing portion 32 so that the movable portion 34 can deform toward the side close to the first fixing portion 32. Two first contact portions 31 protrude from the movable portion 34 into the receiving groove 13 and two bent pieces 35 extend back to the receiving groove 13. The two bent pieces 35 are located on the outside of the wall 12 and are higher than the two first contact portions 31. The upper wall surface of the snap-fit ​​groove F is also higher than the top of the first contact portion 31 of the positive spring piece 3. When the battery 5 is not installed in the receiving groove 13, the two bent pieces 35 are blocked by the outer wall surface of the wall 12 to limit the movable portion 34, and as shown Figure 14 and Figure 16 As shown, when the battery 5 is loaded into the receiving slot 13, the side surface of the battery 5 abuts the movable portion 34, and the two first contact portions 31 of the positive electrode spring 3 are located on the upper side of the battery 5 and electrically contact the upper surface of the battery 5. When the battery 5 needs to be removed, the movable portion 34 can be pushed further toward the side close to the first fixing portion 32, so that the two first contact portions 31 of the positive electrode spring 3 also move outward and no longer block the upper side of the battery 5, thereby allowing the battery 5 to be removed. Figure 15 As shown, the substrate portion 21 is provided with two recessed grooves 211' on one side close to the positive spring piece 3. The two first contact portions 31 of the positive spring piece 3 are respectively accommodated in the two recessed grooves 211', thereby preventing the cover body 2 from accidentally hitting the two first contact portions 31 of the positive spring piece 3 when the cover body 2 is inserted at an angle, thereby facilitating the first contact portion 31 of the positive spring piece 3 to maintain good contact with the battery 5 and preventing the battery 5 from moving upward. An observation hole L is provided through the substrate portion 21 in the vertical direction. External personnel or external detection equipment can detect whether the battery 5 has been installed in the base body 1 through the observation hole L. Figure 15The diameter of the observation hole L is smaller than the distance between the two first contact portions 31 of the two positive springs 3 , so the observation hole L has a smaller size, preventing children's fingers from reaching into the observation hole L and touching the battery 5 .

[0052] like Figure 10 and Figure 14 As shown, the positive electrode spring piece 3 and the slot 121 are arranged opposite to each other along the front-to-back direction and are respectively located on opposite sides of the battery 5. The negative electrode spring piece 4 is installed on the bottom wall 11 of the base body 1. When viewed along the front-to-back direction, the negative electrode spring piece 4 can be exposed in the slot 121. The negative electrode spring piece 4 is arranged closer to the buckle portion 141 than the positive electrode spring piece 3. Figure 16 The first fixing portion 42 of the negative electrode spring 4 is inserted and fixed to the bottom wall 11, and a second contact portion 41 extends obliquely from the first fixing portion 42 toward the receiving groove 13. The height of the second contact portion 41 of the negative electrode spring 4 is lower than the height of the first contact portion 31 of the positive electrode spring 3. The second contact portion 41 of the negative electrode spring 4 is in electrical contact with the lower surface of the battery 5.

[0053] like Figure 14 As shown, two elastic arms 22" are provided from the other end of the base portion 21 relative to the limit block H, extending forward and backward. An operating portion 221" is provided on the side of each elastic arm 22" away from the base portion 21. A locking segment 23" is extended downward from the operating portion 221" of each elastic arm 22". Each locking segment 23" includes an extending portion 231" extending downward from the corresponding elastic arm 22" and a holding portion 232" provided on the extending portion 231" to be locked and fixed with the corresponding locking portion 141, as shown in FIG. Figure 18 As shown, the two locking portions 141 are respectively formed concavely from the sides of the two mounting portions 14 facing each other, and the two holding portions 232 ″ are respectively formed convexly from the sides of the two extending portions 231 ″ facing away from each other.

[0054] When the cover 2 is mounted on the base 1, one end of the cover 2 provided with the locking section 23" is pressed downward, and the two holding portions 232" are pushed by the first inclined surfaces 142 of the two mounting portions 14, causing the two elastic arms 22" to deviate toward each other, and the two locking sections 23" are guided to move downward into the slot 121 through the cooperation of the first inclined surface 142 and the second inclined surface 233". Two anti-excessive deflection surfaces M are provided on the two side surfaces facing each other of the two elastic arms 22". The two anti-excessive deflection surfaces M can abut against each other to prevent the two elastic arms 22" from excessively deviating toward each other. Specifically, the anti-excessive deflection surfaces M The two side surfaces of the two operating portions 221" face each other. When the two operating portions 221" are not offset toward each other, the gap between the two anti-excessive offset surfaces M is larger than the protruding size of the retaining portion 232" to allow the extension portion 231" and the operating portion 221" to be offset and deformed inward at the same time, thereby avoiding the problem that the extension portion 231" and the operating portion 221" cannot be offset inward together during the installation of the cover body 2, causing the connection between the two to be broken due to excessive force. When the pressing stops, the two elastic arms 22" return to the state of not being offset toward each other by their own elastic force, and at this time the retaining portion 232" is snapped into the retaining portion 141. The two anti-excessive offset surfaces M are arranged closer to the two extension portions 231", that is, the gap between the two anti-excessive offset surfaces M is smaller than the distance between the two extension portions 231", thereby avoiding the gap between the two anti-excessive offset surfaces M being too large, which may cause children to easily insert their fingers into the slot 121 and touch the battery 5.

[0055] When the battery 5 needs to be removed, the two operating parts 221" are pressed in the left and right directions to make the two elastic arms 22" deviate toward each other. The extension part 231" and the operating part 221" can simultaneously deviate and deform inward until the two holding parts 232" are disengaged from the two snap parts 141 respectively. Then, the side of the cover body 2 with the two elastic arms 22" is lifted upward to make the locking section 23" of the cover body 2 upwardly exit the slot 121 of the base body 1. Then, the cover body 2 is pulled out at an angle to make the two limit blocks H of the cover body 2 exit the two snap-fitting slots F of the base body 1, so that the cover body 2 is removed. Then, the positive electrode spring piece 3 is pulled in the direction away from the receiving slot 13, and finally, the battery 5 is ejected from one side of the slot 121.

[0056] When the force applied to the two operating parts 221" is too large, the two anti-excessive deflection surfaces M can abut against each other to prevent the two elastic arms 22" from excessive deflection, deformation or breakage, thereby strengthening the structural strength of the elastic arms 22" to increase the service life of the cover 2 and ensuring that the locking section 23" can be normally snapped into the snap portion 141 during subsequent installation and use of the cover 2, so that the cover 2 can well cover and protect the battery 5. In other embodiments, the side surface of at least one additional part 24" located on the elastic arm 22" and the side surface of the elastic arm 22" opposite thereto constitute two anti-excessive deflection surfaces M, and the side surface of the additional part 24" and the side surface of the elastic arm 22" opposite thereto abut against each other to prevent the two elastic arms 22" from excessive deflection. In other embodiments, other protruding structures can also be provided on the base 1, and the two anti-excessive deflection surfaces M of the two elastic arms 22" respectively abut against the protruding structures to prevent the two elastic arms 22" from excessive deflection.

[0057] like Figure 13 、 Figure 15 、 Figure 18 As shown, when the cover 2 is mounted on the base 1, the wall 12 shields most of the side surface of the battery 5, the two locking segments 23" are located in the slot 121 to shield the side surface of the battery 5 exposed in the slot 121, and the distance between the two locking segments 23" is less than the width of a child's finger, so that it is not easy for a child to touch the battery 5. The base portion 21 and the two elastic arms 22" shield the upper surface of the battery 5, and at least one additional portion 24" is formed from the side where the two elastic arms 22" are close to each other along the left and right directions. The projection of one additional portion 24" in the horizontal direction overlaps with the projection of the operating portion 221". Multiple additional portions 24" can strengthen the two The strength of each elastic arm 22" makes the two elastic arms 22" not easy to break, and the multiple additional parts 24" on the two elastic arms 22" are staggered in the left and right directions. The multiple additional parts 24" fill the gap between the two elastic arms 22", preventing children's fingers from reaching into the receiving groove 13, and can cover the part of the upper surface of the battery 5 exposed between the two elastic arms 22". Therefore, the battery holder formed by the cover body 2 and the base body 1 well covers and protects the battery 5, and the multiple additional parts 24" can also be used to block 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. After the cover body 2 is installed, the top surface of its elastic arm 22" is lower than the first top surface 127 of the wall 12, that is, the setting of the elastic arm 22" will not additionally increase the height of the battery holder 100, so that the battery holder 100 can maintain its original height, which is conducive to the miniaturization of the battery holder 100.

[0058] See also Figure 13 、 Figure 14 and Figure 15The base portion 21 extends along the front-to-back direction with two shielding portions 212' respectively located on the two outer sides of the two elastic arms 22". The shielding portions 212' are used to shield part of the upper surface of the battery 5. There is a slit between each shielding portion 212' and each elastic arm 22", so that the elastic arm 22" can be deformed independently of the shielding portion 212' and has good elasticity. The shielding portion 212' is located on the inner side of the enclosure 12 and is provided with a card point P to abut against the enclosure 12. Even if a child accidentally operates the elastic arm 22" and deforms it, the card of the shielding portion 212' Point P still maintains a relatively tight interference fit with the wall 12, thereby increasing the upward pulling force of the cover body 2 as a whole, and making it difficult for children to easily remove the cover body 2. A support portion 213 is formed outwardly from one side of each shielding portion 212'. The bottom surface of the support portion 213 is higher than the bottom surface of the shielding portion 212', and the top surface of the support portion 213 is higher than the top surface of the base portion 21. The bottom surfaces of the two support portions 213 are supported by the upper surface of the wall 12, and the two support portions 213 and the two elastic arms 22" are located on the same side of the base portion 21. Figure 13 and Figure 14 The two support parts 213 and the two elastic arms 22" are all located on the front side of the base plate part 21, and the limit block H is located on the rear side of the base plate part 21. The upper surface of the wall 12 blocks the two support parts 213 from moving downward, preventing the two elastic arms 22" and the two locking segments 23" from moving downward due to gravity, which would cause the two holding parts 232" to loosen from the two snap parts 141. Each operating part 221" is correspondingly located above the second top surface 128 of each mounting part 141. The second top surface 128 blocks the operating part 221" from moving downward, so as to further prevent the snap parts 232" from loosening from the snap parts 141, so that the cover body 2 can be more firmly installed on the base body 1 in the up and down directions. In this embodiment, the two operating parts 221" are respectively located above the two mounting parts 14, and the two outer edges of the two operating parts 221" that are opposite to each other extend outward from the outer edges of the second top surface 128 in the left and right directions by a distance W1 that is less than the size of the snap parts 232" protruding in the left and right directions. Inch W2, during the testing of the battery holder, if a detection component accidentally touches the outer edge of the operating portion 221" and the outer wall of the mounting portion 14 simultaneously along the second direction, the detection component will actuate the operating portion 221" to deflect inward but will be blocked by the outer edge of the mounting portion 14, so that the operating portion 221" cannot deflect further inward, and the distance the operating portion 221" deflects inward is not enough to allow the retaining portion 232" to disengage from the latch portion 141, thereby preventing the cover 2 from accidentally disengaging. In other embodiments, W1 can be 0, that is, the outer edge of the operating portion 221" is aligned with the outer edge of the second top surface 128.

[0059] In summary, the battery holder 100 of the present invention has the following beneficial effects:

[0060] (1) A limit block H is provided on one side of the base portion 21, and an elastic arm 22" and a locking section 23" are provided on the other side. When assembling, the side of the base portion 21 provided with the limit block H is first inserted obliquely into the base body 1 and into the receiving groove 13 to prevent the two locking sections 23" from colliding with the top of the base body 1 and being damaged, so that the two locking sections 23" can smoothly enter the slot 121. The two locking sections 23" are offset in a direction close to each other and are simultaneously locked downward into the two locking parts 141, limiting the upward movement of the cover body 2 relative to the base body 1. The limit block H of the cover body 2 and the locking section of the cover body 2 23" together fix the cover body 2 and the base body 1 to ensure the firmness and stability of the battery holder 100 structure; the base plate portion 21 and the two elastic arms 22" together cover the upper surface of the battery 5, and the two locking segments 23" cover part of the side surface of the battery 5 in the slot 121, making it difficult for children to find the battery 5, preventing children from reaching into the slot 13 from the top of the receiving slot 13 or from the slot 121 to remove the battery 5, and preventing children from accidentally swallowing the battery 5. Even in the case of long-term vibration, the cover body 2 can stop the battery 5 and prevent the battery 5 from falling out of the receiving slot 13.

[0061] (2) Anti-excessive deflection surfaces M are provided on the two side surfaces facing each other of the two elastic arms 22″ to prevent the two elastic arms 22″ from excessively deflecting toward each other due to uneven force, thereby preventing the locking section 23″ from being properly released, and to prevent the two elastic arms 22″ from excessive deformation and breakage, thereby ensuring that the locking section 23″ and the buckle portion 141 are subsequently normally engaged so that the cover body 2 can be firmly fixed on the base body 1 to well shield and protect the battery 5.

[0062] (3) When the two operating parts 221" are not offset toward each other, the gap between the two anti-excessive offset surfaces M is larger than the protruding size of the latching part 232", so that during the process of installing the cover body 2 and locking it to the base body 1, the extension part 231" and the operating part 221" can both be offset and deformed inwardly at the same time until the latching part 232" locks the latching part 141, avoiding the problem that the extension part 231" and the operating part 221" cannot be offset inwardly together during the installation of the cover body 2, causing the connection between the two to be broken due to excessive force, and the gap between the two anti-excessive offset surfaces M is smaller than the two extension parts. 231", to prevent the gap between the two anti-over-drift surfaces M from being too large, which may cause children's fingers to easily reach into the slot 121 and touch the battery 5. When the cover 2 needs to be removed, if the force of pressing the two operating parts 221" is too large, the two anti-over-drift surfaces M can be pressed together to prevent the two elastic arms 22" from further excessive deflection and breakage, thereby strengthening the structural strength of the elastic arms 22" to increase the service life of the cover 2, and ensuring that the locking section 23" of the cover 2 can be normally buckled in the buckle part 141 during the subsequent installation and use of the cover 2, so that the cover 2 can well shield and protect the battery 5.

[0063] (4) The additional portion 24" is formed by protruding from the side where the two elastic arms 22" are close to each other along the second direction, thereby strengthening the strength of the two elastic arms 22" and making the two elastic arms 22" less likely to break. Each additional portion 24" is staggered with other additional portions 24" in the extension direction of the elastic arm 22". Multiple additional portions 24" fill the gap between the two elastic arms 22" to prevent children's fingers from reaching between the two elastic arms 22" to touch the internal battery 5. Multiple additional portions 24" are used to block 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, and the distance between the two locking segments 23" is less than the width of a child's finger, making it difficult for a child to find the battery 5, and a child's finger cannot reach between the two locking segments 23" to touch the battery 5, thereby well shielding and protecting the battery 5.

[0064] (5) After the locking section 23″ is locked with the locking portion 141, the top surface of the elastic arm 22″ is lower than the first top surface 127, that is, the setting of the elastic arm 22″ does not increase the height of the battery holder 100, so that the battery holder 100 can maintain its original height, which is conducive to the miniaturization of the battery holder 100.

[0065] The above detailed description is only an illustration 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 invention are included in the patent scope of this invention.
