Therefore, the detachable connection of the battery tray 2 and the battery bin 10 can be realized, the connection structure of the elastic buckle and the clamping groove is simpler, the manufacture is convenient, and the cost is saved.

In some embodiments, referring to fig. 5 to 6, the battery tray 2 includes a bottom plate 21, a cover plate 22 coupled to an edge of the bottom plate 21, and a battery frame 23 disposed on the bottom plate 21, the battery frame 23 and the bottom plate 21 forming a battery compartment 20; the bottom plate 21 is provided with a conductive opening 210 corresponding to the battery jar 20. Therefore, the battery groove 20 is formed in a simple manner, the battery groove 20 is more matched with the battery 100, the battery tray 2 can be connected with the circuit board 3 through the conductive opening 210 after being inserted into the battery compartment 10, no additional connecting step is needed, and the assembly process of the opening and closing sensor is simplified.

In some embodiments, the battery tray 2 is similar to a drawer, the bottom plate 21, the cover plate 22 and the battery jar 20 of the battery tray 2 may be integrally formed, for example, a cuboid similar to a drawer may be formed, a groove is formed on the surface of the cuboid as the battery jar 20, and a through hole penetrating through the bottom surface of the groove is formed on the bottom surface of the groove as the conductive opening 210, so that the battery tray 2 is a whole and is more durable.

In this embodiment, the bottom plate 21, the cover plate 22 and the battery frame 23 of the battery tray 2 are of separate and split structures, so that the steps of forming grooves and through holes are not needed, the manufacturing steps of the battery tray 2 can be simplified, and the materials for manufacturing the battery tray 2 can be saved. The battery frame 23 is arranged on the bottom plate 21 of the battery tray 2 to form the battery groove 20, and the battery frame 23 can be replaced according to different shapes of the battery 100, so that when the opening and closing sensor is manufactured, the bottom plate 21 and the cover plate 22 can be universal for manufacturing the battery tray 2, and when the opening and closing sensor of the battery 100 with different shapes and specifications is required to be installed, only the different battery frames 23 are required to be arranged on the bottom plate 21, so that the manufacturing efficiency of the opening and closing sensor is further improved, and the batch production of the opening and closing sensors with different specifications is facilitated.

By way of example, the battery frame 23 in the embodiment of the application is arc-shaped, so that a circular battery groove 20 is formed, a circular battery 100 can be placed, two battery grooves 20 can be arranged on the battery tray 2 in parallel, and thus two batteries 100 can be placed, so that the power supply electric energy of the opening and closing sensor is increased, the power supply time is effectively prolonged, the opening and closing sensor is beneficial to long-time use, and the use experience of a user is improved.

In this application embodiment, when battery frame 23 is convex, can set up the connecting plate between battery frame 23 lateral surface and apron 22, be provided with second joint portion 5 on the one side surface that the battery compartment 10 was kept away from to the connecting plate, when second joint portion 5 was the elasticity buckle, can set up convex in the arc on the one side surface that the battery compartment 10 was kept away from to the connecting plate, convex in the arc adopts elastic material preparation, also can set up the connecting plate into the slice, and the connecting plate is crooked also can realize the effect that convex in the arc compressed to one side of battery compartment 10.

In some embodiments, referring to fig. 6, a side surface of the circuit board 3 adjacent to the battery compartment 10 is provided with a conductive electrode 31 and a stopper 32, and the stopper 32 is used to stop the battery tray 2 so that the battery 100 is connected with the conductive electrode 31 through the conductive opening 210. The battery tray 2 can not always move to the inside of the battery compartment 10 when being inserted into the battery compartment 10 through the arrangement of the stop piece 32, but can stop moving when reaching the preset position, and the battery 100 can just face the conductive electrode 31 at the moment, so that the accurate connection between the battery 100 and the conductive electrode 31 is realized.

It should be noted that the stopper 32 serves to stop the movement of the battery tray 2, and thus the specific structure of the stopper 32 is not particularly limited. Specifically, the stop member 32 may be a protrusion, so that when the battery tray 2 is inserted into the battery compartment 10, the battery frame 23 or the battery 100 will abut against the stop member 32 to prevent the battery tray 2 from moving further.

Of course, the stop member 32 may also be a circular arc-shaped sheet structure, when the battery 100 is circular, and the battery frame 23 is circular, the battery frame 23 may be an entire ring, and all surrounds the battery 100, and at this time, the stop member 32 is adapted to the shape of the outer surface of the battery frame 23, so that the stop area can be increased, and the stop effect is better; the battery frame 23 may also be a ring with an opening, and the opening is opposite to the stop piece 32, at this time, the stop piece 32 abuts against the battery 100, and the stop piece 32 and the battery frame 23 together form a whole ring, so that not only can the function of stopping the movement of the battery tray 2 be played, but also the battery frame 23 has an opening, so that a user can take out the battery 100 from the battery groove 20 from the opening when replacing the battery 100, and the battery 100 can be replaced more conveniently.

In some embodiments, referring to fig. 6, the conductive electrode 31 is a conductive dome. Therefore, when the stop piece 32 stops the battery tray 2 from moving, the battery 100 is opposite to the conductive electrode 31, and the conductive spring piece is adopted as the conductive electrode 31, so that the conductive electrode 31 can be ensured to be abutted against the battery 100, and the electric connection performance of the battery 100 and the conductive electrode 31 is ensured to be more stable.

It should be noted that, the number of the conductive elastic pieces may be the same as the number of the batteries 100, the conductive electrode 31 in the embodiment of the present application is a negative conductive electrode 31, and after the battery tray 2 is inserted into the battery compartment 10, the negative surface of the circular battery 100 abuts against the conductive elastic pieces to realize stable electrical connection.

In some embodiments, battery 100 abuts the inner surface of battery well 20. Therefore, the battery 100 is not easy to fall off from the battery groove 20 after being placed in the battery groove 20, so that the phenomenon of falling off caused by displacement of the battery 100 in the process of inserting the battery tray 2 into the battery compartment 10 is avoided, the battery 100 is not moved due to shaking movement of the opening and closing sensor after being in contact electrical connection with the conductive electrode 31, and the electrical connection performance of the battery 100 and the conductive electrode 31 is ensured to be more stable.

In addition, since the battery 100 is abutted against the inner surface of the battery holder 20, no matter the battery tray 2 is inserted into the battery compartment 10 with the bottom plate 21 facing upwards or is inserted into the battery compartment 10 with the battery frame 23 facing upwards, the battery 100 will not fall out of the battery holder 20, so that the limitation of inserting and extracting the battery tray 2 from the battery compartment 10 is reduced, and the user can insert and extract the battery tray 2 from the battery compartment 10 quickly and conveniently to replace the battery 100.

In some embodiments, referring to fig. 7, the cover 22 is provided with a notch 220 on a side near the upper cover 101, and a projection 1010 for fitting a portion of the notch 220 is provided on a side of the upper cover 101 facing the lower cover 102. Thus, a gap formed by the notch 220 is formed between the cover plate 22 and the upper cover 101, so that a user can conveniently pull the battery tray 2 out of the battery compartment 10.

It should be noted that, the notch 220 is disposed on the side of the cover 22 near the upper cover 101, so that a gap with a certain width exists between the cover 22 and the upper cover 101, which is more convenient for a user to insert the battery tray 2 into the battery compartment 10 and pull out the battery tray 2 from the battery compartment 10 by holding the battery tray by hand. The bump 1010 for adapting to a part of the notch 220 is provided on the side of the upper cover 101 facing the lower cover 102, so that the direction of inserting the battery tray 2 into the battery compartment 10 can be identified by a user according to the bump 1010, so that the user can smoothly insert the battery tray 2 into the battery compartment 10 at a time, and repeated direction adjustment can not occur.

In some embodiments, the cover 22 is provided with a notch 220 on a side near the lower cover 102, and a projection 1010 for fitting a portion of the notch 220 is provided on a side of the lower cover 102 facing the upper cover 101. Thus, a gap formed by the notch 220 is formed between the cover plate 22 and the upper cover 101, so that a user can conveniently pull out the battery tray 2 from the battery compartment 10, and the arrangement of the convex blocks 1010 can help the user to quickly identify the direction of inserting the battery tray 2 into the battery compartment 10, so that the user can smoothly insert the battery tray 2 into the battery compartment 10 once, and the situation of repeatedly adjusting the direction can not occur.
