[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1-7 shown, a snap-in battery compartment structure is installed inside a mother and baby lamp, including a housing. A battery 3 is installed inside the housing. The housing includes a left housing 1 and a right housing 2. The left housing 1 and the right housing 2 enclose each other to form a receiving cavity for receiving the battery 3. The circumferential side of the left housing 1 is provided with an outwardly protruding first fastening portion 11, and the right housing 2 is provided with a second fastening portion 21 corresponding to the first fastening portion 11. The first fastening portion 11 and the second fastening portion 21 are snap-connected, and the snap-in portion forms a positioning strip that extends along the axial direction of the housing. A card slot adapted to the positioning strip is provided inside the lamp. The positioning strip is cooperatively connected with the card slot.

[0032] In this embodiment, the length of the positioning strip is greater than 2 / 3 of the length of the housing, so that the positioning strip forms a line-plane contact with the mother and baby lamp, improving the positioning effect of the positioning strip.

[0033] A positioning groove corresponding to the positioning strip is provided inside the mother and baby lamp. When the battery 3 compartment is installed inside the mother and baby lamp, the positioning strip is inserted into the positioning groove to prevent the battery 3 compartment from loosening after the mother and baby lamp shakes or is collided. At the same time, the battery 3 is fixed inside the battery 3 compartment through the elastic unit 22 to prevent the battery 3 from shaking inside the battery 3 compartment.

[0034] In this embodiment, a plurality of fastening grooves 111 are provided on the first fastening portion 11, and fastening hooks 211 corresponding to the fastening grooves 111 are provided on the second fastening portion 21. When the first fastening portion 11 and the second fastening portion 21 are attached, the fastening hooks 211 are fastened in the fastening grooves 111. When the fastening hooks 211 are fastened to the fastening grooves 111, the fastening hooks 211 are deformed, pass through the fastening grooves 111, and return to their original shape when passing through the fastening grooves 111, so that the fastening hooks 211 are fastened to the fastening grooves 111, thereby fixing the left housing 1 and the right housing 2 together.

[0035] Specifically, the fastening hook 211 includes a hook portion 2111 in a hook shape, and the hook portion 2111 is provided with an inclined transition surface 2112. The transition surface 2112 is used to gradually deform the fastening hook 211, prevent the fastening hook 211 from being deformed too much in a short time, resulting in damage to the fastening hook 211, and improve the reliability of the fastening hook 211.

[0036] In this embodiment, limiting portions 12 extending in the radial direction of the outer shell are provided on the inner sides of the end faces at both ends of the left housing 1. When the first fastening portion 11 and the second fastening portion 21 are fastened and connected, the limiting portions 12 extend into the right housing 2 and are respectively abutted against the inner sides of the end faces at both ends of the right housing 2. The limiting portions 12 are used to limit the relative positions of the left housing 1 and the right housing 2, prevent the left housing 1 and the right housing 2 from being misaligned when fastened, achieve the effect of quick alignment, and improve the convenience when the left housing 1 and the right housing 2 are fastened.

[0037] A plurality of elastic units 22 are further provided on the right housing 2. The elastic units 22 pass through the side wall of the right housing 2 from outside to inside and are in contact with the battery 3, pressing the battery 3 tightly.

[0038] In this embodiment, the elastic unit 22 is a spring piece, and the spring piece is integrally formed with the right housing 2, reducing the subsequent installation steps and improving the convenience when assembling the battery 3 compartment.

[0039] Specifically, the elastic unit 22 includes a contact portion 221 adapted to the battery 3, and deformation portions 222 symmetrically arranged on both sides of the contact portion 221. When the elastic unit 22 presses the battery 3 tightly, the deformation portions 222 are deformed to drive the contact portion 221 to press the battery 3 tightly.

[0040] Specifically, the number of the elastic units 22 is 2. Two points determine a straight line. By pressing the battery 3 with two elastic units 22, it is possible to prevent the battery 3 from swaying in the battery 3 compartment, resulting in poor contact, and improve the reliability of the battery 3 compartment.

[0041] In this embodiment, a buffer pad 4 is further provided in the housing and is arranged opposite to the elastic unit 22, and the buffer pad 4 abuts against the battery 3. The buffer pad 4 is made of a flexible material and has a certain deformation ability. Since there is an error between the batteries 3, when the size of the battery 3 is too large, the pressure received also increases, and there is a risk of crushing the battery 3. The buffer pad 4 can deform according to the size of the battery 3 to buffer the battery 3, prevent the battery 3 from being damaged due to excessive pressure, and improve the reliability of the battery 3 compartment.

[0042] In this embodiment, a conductive unit 5 is further provided in the shell, one end of the conductive unit 5 is electrically connected to the battery 3, and the other end passes through the shell from the inside to the outside and is electrically connected to the control unit of the mother and baby lamp.
