[0040] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0041] In order to make the person skilled in the art better understand the utility model scheme, the utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0042] The utility model embodiment discloses a battery compartment, like the drawings Figure 1 And 2As shown, it comprises a shell body 10, in which a battery compartment 11 is formed, which is adapted to place a 18650 battery. The depth, width and length of the battery compartment 11 can be adjusted according to the specifications of the battery 20, which is not specifically limited here.

[0043] It should be noted that, no matter whether the limiting block 14 is flipped to the first position or the second position, a small gap needs to be left in the length direction of the battery compartment 11 to facilitate the taking and placing of the battery 20. After the battery 20 is installed, this gap needs to ensure that the negative spring 131 and the positive spring 12 can respectively correspond to the negative and positive ends of the battery 20. The size of this gap is small, and the two ends of the battery 20 are in elastic contact, which can ensure that the two ends of the battery 20 are still in good contact when the battery 20 is subjected to external force impact, and power failure will not occur.

[0044] As shown in the accompanying drawings Figure 2 As shown, the two ends of the battery compartment 11 are respectively provided with a positive spring 12 and a negative spring 13. The positive spring 12 and the negative spring 13 respectively elastically abut against the two ends of the battery 20. The positive spring 12 specifically abuts against the positive end of the battery 20, and the negative spring 13 specifically abuts against the negative end of the battery 20, thereby ensuring that the battery 20 is connected with the circuit in the battery compartment 11, and the battery 20 realizes power supply.

[0045] The battery compartment 11 is provided with a flipable limiting block 14, which adjusts the length of the battery compartment 11, so that the battery compartment 11 can adapt to batteries 20 of different lengths.

[0046] When a battery 20 with a shorter length, for example, a battery 20 with a length of 65mm, is used, the two ends of the battery 20 elastically abut against the positive spring 12 and the negative spring 13 respectively, and at the same time, the limiting block 14 is flipped to the first position, as shown in the accompanying drawings Figure 3 and 4 As shown, the limiting block 14 is perpendicular to the center line of the battery compartment 11. At this time, the limiting block 14 is in an upright state, the limiting block 14 abuts against the end of the battery 20, the limiting block 14 divides the space of the battery compartment 11, and reduces the activity space of the battery 20 in the battery compartment 11. One end of the battery compartment 11 and the limiting block 14 together provide rigid limiting for the two ends of the battery 20, so that the shorter battery 20 will not power failure when subjected to external force impact.

[0047] When a battery 20 with a longer length, for example, a battery 20 with a length of 70mm, is used, the two ends of the battery 20 elastically abut against the positive spring 12 and the negative spring 13 respectively, and at the same time, the limiting block 14 is flipped to the second position, as shown in the accompanying drawings Figure 5 and 6As shown, the limiting block 14 is parallel to the center line of the battery compartment 11, at this time, the limiting block 14 is in a laid-down state, the battery 20 is parallel to the limiting block 14, at this time, the battery 20 is pressed on the limiting block 14, the active space in the battery compartment 11 is not affected by the limiting block 14, the two ends of the battery compartment 11 provide rigid limiting for the two ends of the battery 20, so that the longer battery 20 will not be powered off when bearing external force impact.

[0048] The utility model discloses a limiting block 14 is added in the battery compartment 11 can overturn, makes the battery compartment 11 can provide rigid limiting for the battery 20 of different length, reduces the risk of the battery 20 and breaks down because of external force impact, avoids appearing the problem of battery 20 contact badly, and the battery 20 supplies power more stably, and the user experience is better.

Figure 3 As shown, the negative electrode spring 131 is arranged on the negative electrode spring 131, the limiting block 14 is provided with the avoiding slot 141, and the avoiding slot 141 is specifically a U-shaped slot penetrating along the thickness direction of the limiting block 14. When the limiting block 14 is turned to the first position, the negative electrode spring 131 passes through the avoiding slot 141 and is abutted with the negative electrode spring 131 of the battery 20, so that the limiting block 14 avoids hindering the negative electrode spring 131 and the negative electrode end of the battery 20 from being contacted, ensures that the negative electrode spring 131 and the negative electrode end of the battery 20 are contacted well, and avoids power failure caused by unable contact. The negative electrode spring 131 is specifically a conical spring towards the negative electrode end side of the battery 20, but is not limited to this.

[0052] When the limiting block 14 is flipped to the first position, as shown in FIG. 2, the positioning protrusions 144 of the elastic arms 142 are opposite to the first positioning holes 110, the extrusion force of the side wall of the battery compartment 11 on the elastic arms 142 is reduced, the elastic arms 142 recover from the elastic deformation, the two elastic arms 142 are separated from each other along the width direction of the battery compartment 11, the elastic arms 142 extend out of the accommodating cavities 143 until the positioning protrusions 144 are matched with the first positioning holes 110, so that the limiting block 14 is stably parked at the first position, and reliable rigid support is provided for the battery 20. Figure 3 4 As shown in FIG. 2, the positioning protrusions 144 of the elastic arms 142 are opposite to the first positioning holes 110, the extrusion force of the side wall of the battery compartment 11 on the elastic arms 142 is reduced, the elastic arms 142 recover from the elastic deformation, the two elastic arms 142 are separated from each other along the width direction of the battery compartment 11, the elastic arms 142 extend out of the accommodating cavities 143 until the positioning protrusions 144 are matched with the first positioning holes 110, so that the limiting block 14 is stably parked at the first position, and reliable rigid support is provided for the battery 20.

[0053] When the limiting block 14 is flipped between the first position and the second position, the positioning protrusions 144 are in abutment with the side wall of the battery compartment 11, the extrusion force of the side wall of the battery compartment 11 on the elastic arms 142 causes the elastic deformation of the two elastic arms 142, the two elastic arms 142 are gathered to each other along the width direction of the battery compartment 11, and the elastic arms 142 are compressed into the accommodating cavities 143 under the extrusion of the side wall of the battery compartment 11.

[0054] When the limiting block 14 is flipped to the second position, as shown in FIG. 3, the extrusion force of the side wall of the battery compartment 11 on the elastic arms 142 is reduced, the elastic arms 142 recover from the elastic deformation, the two elastic arms 142 are separated from each other along the width direction of the battery compartment 11, the elastic arms 142 extend out of the accommodating cavities 143 until the positioning protrusions 144 are matched with the second positioning holes 111, so that the limiting block 14 is stably parked at the second position, and reliable rigid support is provided for the battery 20. Figure 5 6 As shown in FIG. 3, the extrusion force of the side wall of the battery compartment 11 on the elastic arms 142 is reduced, the elastic arms 142 recover from the elastic deformation, the two elastic arms 142 are separated from each other along the width direction of the battery compartment 11, the elastic arms 142 extend out of the accommodating cavities 143 until the positioning protrusions 144 are matched with the second positioning holes 111, so that the limiting block 14 is stably parked at the second position, and reliable rigid support is provided for the battery 20.

[0055] As a preferred embodiment, as shown in FIGS. 4, 5 and 7, the two sides of the limiting block 14 are respectively provided with the fitting groove 145 and the abutting surface 146. Considering that the outer side surface of the battery 20 is a cylindrical surface, the fitting groove 145 is specifically an arc groove provided on one side groove of the avoiding groove 141, which ensures the concave-convex fitting of the outer side surface of the battery 20 and the fitting groove 145. The abutting surface 146 is a plane, which is used to limit the placement state of the limiting block 14 at the second position, ensures that the limiting block 14 is parallel to the center line of the battery 20, and avoids the uneven placement of the limiting block 14, which affects the power supply stability of the battery 20. Figure 1 5 When the limiting block 14 is flipped to the second position, the outer side surface of the battery 20 is concave-convex fitted with the fitting groove 145, and the abutting surface 146 is in abutment with the limiting plane 112 provided on the bottom of the battery compartment 11, which avoids the uneven placement of the battery 20 due to the uneven placement of the limiting block 14, ensures that the two ends of the battery 20 are in reliable contact with the positive elastic sheet 12 and the negative elastic sheet 13 respectively, and improves the power supply stability of the battery 20.

[0057] ​​​As a preferred embodiment, as shown in the appendix Figures 1 to 6 As shown, rotating pins 113 are fixed to both sides of the battery compartment 11. One end of the limiting block 14 is hinged to the rotating pin 113, and the other end of the limiting block 14 is provided with a handle groove 147. Specifically, the two sides of the battery compartment 11 are symmetrically provided with transition holes 119, and each transition hole 119 is fixed with a rotating pin 113. The length of the rotating pin 113 is greater than the thickness of the side wall of the battery compartment 11, ensuring that the rotating pin 113 extends into the battery compartment 11 and is hinged to the limiting block 14, so that the rotating pin 113 supports the limiting block 14 to rotate relative to the battery compartment 11. The handle groove 147 makes it convenient for the finger to press the limiting block 14 to flip it over and adjust the placement of the limiting block 14 in the battery compartment 11. This is especially convenient when the limiting block 14 is in the second position, which helps to improve the user experience.

[0058] As a preferred embodiment, as shown in the appendix Figure 1 and 2 As shown, the battery compartment 11 has two symmetrically arranged first limiting protrusions 114 on its two side walls.

A first slot 115 is formed between the first end face of the battery compartment 11 and the first limiting protrusion 114. A bending arm 132 is formed on the top side of the negative electrode spring 13, and the bending arm 132 engages with the first slot 115. It should be noted that the bending arm 132 has a U-shaped cross-section, giving it a certain degree of elasticity. This elastic force allows the bending arm 132 to be fixed between the first end face and the first limiting protrusion 114, ensuring that the negative electrode spring 13 is reliably fixed within the first slot 115.

[0059] In addition to fixing the negative electrode spring 13, the first limiting protrusion 114 also has a limiting function. When the limiting block 14 is flipped to the first position, as shown in the attached figure... Figure 3 As shown, the limiting block 14 abuts against the side of the first limiting protrusion 114 away from the first slot 115. The first limiting protrusion 114 limits the position of the limiting block 14, preventing the limiting block 14 from overturning due to the impact on the battery 20, thereby ensuring that the limiting block 14 provides reliable rigid support for the battery 20.

[0060] As a preferred embodiment, as shown in the appendix Figure 2 As shown, the negative electrode spring 13 is provided with support arms 133 on both sides, and the support arms 133 are bent towards the first end face near the battery compartment 11; specifically, two raised support arms 133 are symmetrically provided on both sides of the negative electrode spring 13; a support boss 134 is formed on the side of the negative electrode spring 13 near the first end of the battery compartment 11, specifically, the support boss 134 is an integrally formed cylindrical boss.

[0061] When the bending arm 132 engages with the first slot 115, the support arm 133 and the support boss 134 abut against the first end face of the battery compartment 11. The support arm 133 undergoes elastic deformation, so that the negative electrode spring 13 is reliably fixed in the first slot 115 by the spring of the support arm 133. The support boss 134 increases the contact area between the negative electrode spring 13 and the first end face of the battery compartment 11, ensuring that the negative electrode spring 13 is stably fixed in the first slot 115.

[0062] A raised rib 116 is formed on the first end face of the battery compartment 11, as shown in the attached figure. Figure 1 As shown, the bending arm 132 abuts against the protruding rib 116 and the first limiting protrusion 114 to ensure that the negative electrode spring 13 is reliably fixed in the first slot 115, so that the negative electrode spring 13 can withstand a strong impact.

[0063] As a preferred embodiment, as shown in the appendix Figure 1 As shown, the battery compartment 11 has two relatively extended second limiting protrusions 117 on its two side walls. Two second limiting protrusions 117 are symmetrically arranged on the two side walls of the battery compartment 11. The two second limiting protrusions 117 are located near the second end of the battery compartment 11, and a clearance gap is formed between the two second limiting protrusions 117 for engaging the elastic piece 122 of the positive electrode spring 12. A second slot 118 is formed between the second end face of the battery compartment 11 and the second limiting protrusions 117. A snap-fit ​​arm 121 is provided on the top side of the positive electrode spring 12. The snap-fit ​​arm 121 engages with the second slot 118. The cross-section of the snap-fit ​​arm 121 is U-shaped to ensure that the positive electrode spring 12 is reliably fixed in the second slot 118 by the elastic force of the snap-fit ​​arm 121. On the side of the positive electrode spring 12 away from the second end face of the battery compartment 11, there is an elastic piece 122. A protrusion 123 is formed on one side of the elastic piece 122. The protrusion 123 abuts against the positive electrode of the battery 20 to ensure reliable contact between the positive electrode spring 12 and the positive electrode of the battery 20, and to ensure that the outer skin of the battery 20 is not scratched during the process of taking it out and putting it in.
