In order to better understand the aspects of the present utility model, the present utility model will be described in further detail with reference to the drawings and embodiments.

As shown in fig. 3-5, an embodiment of the present utility model provides a lock for a space suitcase, which is used for storing important files and objects, and comprises a housing 1, a rear cover 2 connected with the housing, a PCB main board 3 arranged in the housing, and a latch assembly 4 arranged in the housing, wherein the latch assembly comprises a latch 401; a driving member 5 for driving the latch bolt assembly to move relative to the rear cover; the lock tongue extends outwards from a rear perforation 201a in the rear cover plate 201 and can move relative to the rear cover; the driving member 5 is electrically connected with the PCB main board 3.

The Bluetooth module or other wireless modules are further arranged on the PCB main board 3, and the connection between terminals such as mobile phones and locks is realized through the wireless modules, namely, the prior art is adopted, an app is installed on the mobile phones, and after the mobile phones are in wireless connection with the locks, a fixed password, a one-time password and the like can be set through the app; the lock can also be directly unlocked through a mobile phone, and the use is very convenient.

As shown in fig. 1-2 and 8a, in order to cooperate with the lock tongue 401, the box further comprises a fixing seat 15 fixedly arranged on the box body, and a fastening portion 1501 cooperating with the lock tongue is arranged in the fixing seat. The case here refers to a suitcase fitted with locks.

Specifically, as shown in fig. 5-6, the latch bolt assembly 4 includes a main body 402, a driving inner hole 403 disposed in the main body, a driving tooth portion 404 disposed on an upper surface of the driving inner hole, and two return springs 405 disposed on left and right sides of the main body respectively; the inner ends of the two return springs are respectively abutted with the left side surface and the right side surface of the body, and the outer ends of the two return springs are respectively abutted with the inner walls of the two sides of the shell 1. During assembly, one end of the body 402 opposite to the set lock tongue extends into the housing 1, and a cavity 104 for accommodating the end of the body is arranged in the housing, at this time, one end of the return spring 405 is connected with the side surface of the body, while the other end is abutted against the side inner wall of the housing 1, and in an initial state, the state of the return spring can be the original length, that is, in an uncompressed state.

As shown in fig. 6 and 9a, the driving member 5 includes a motor 501, and a driving gear 502 disposed at one end of the motor; the driving gear extends into the driving inner hole 403 to be meshed with the driving tooth part 404; the driving tooth part is a section of straight tooth.

More specifically, the driving inner hole 403 includes two clearance portions respectively located at two sides of the driving tooth portion 404, and two arc-shaped recesses 403a communicating with the clearance portions are respectively disposed in two side walls of the driving inner hole; upon completion of unlocking or locking, the drive gear 502 is located in one of the clearance portions and one of the return springs 405 is compressed. The purpose of adopting this structure is that, in the unlocking state, as shown in fig. 8a, the latch bolt assembly moves integrally, so that the driving gear 502 is located in the clearance portion on the right side of the driving gear 404, at this time, the return spring 405 located on the left side is compressed, and since the driving gear is a straight tooth, after the driving gear 502 rotates with the motor 501 by a certain angle, the latch bolt assembly reaches its maximum stroke, and the driving gear 404 is separated from the driving gear 502, at this time, the driving gear 502 can idle in the clearance portion, so that the motor stall can be reduced, and the service life of the motor can be prolonged; in this state, when locking is required, the motor 501 drives the driving gear 502 to rotate clockwise, and after engaging with the driving gear 404, the driving gear 502 moves rightward with the latch bolt assembly until the latch bolt enters the fastening portion 1501, and thus the locking state is entered, at this time, the driving gear 502 enters the left side of the driving gear 404 and idles in the clearance portion, the right side return spring 405 is compressed, and although the reset pressure of the right side return spring urges the driving gear 404 to approach the driving gear 502, the driving gear 502 idles clockwise, so the driving gear 502 does not mesh together, as shown in fig. 9a, if the driving gear 502 rotates counterclockwise at this time, the driving gear 502 can be meshed together under the reset pressure of the return spring.

In order to facilitate setting more complex passwords and inputting passwords, as shown in fig. 1-5, a plurality of key holes 103 are arranged in a panel 102 of the shell 1; still further include the password button group 14 that comprises a plurality of buttons, a plurality of buttons locate respectively in a plurality of key holes and password button group and PCB mainboard 3 electricity are connected.

As shown in fig. 2, a mounting bracket 8 for mounting the battery 7 is provided in the battery compartment 203, a power PCB 9 electrically connected with the battery is provided on the mounting bracket, and a positive contact and a negative contact 10 are provided on the power PCB. In order to save the installation space, the battery here adopts a button battery.

As shown in fig. 2, in order to realize connection between the power PCB 9 and the PCB main board 3, a PCB connecting board 11 is further disposed in the housing 1 and located between the power PCB 9 and the PCB main board 3, two conductive springs 12 are disposed on one surface of the PCB connecting board, and free ends of the two conductive springs are respectively contacted with the positive and negative contacts 10; the PCB main board is electrically connected with the PCB connecting plate 11.

The structure is used for realizing the installation of the power supply assembly and the control assembly, and is beneficial to simplifying the design and saving the installation space.

As shown in fig. 2, the PCB connecting plate 11 is provided with a USB power supply interface 13, and a through hole 101 for accommodating the USB power supply interface is provided in the housing 1, and the USB power supply interface is exposed from the opening of the through hole. When not used in daily life, a rubber plug 16 which is convenient to insert and pull is arranged at the opening of the perforation 101; a battery compartment fixing plate 17 detachably connected with the rear cover plate 201 is provided at an opening of the battery compartment 203. When the button battery is not powered and is not replaced in time, the USB power supply interface 13 can be used for emergency power supply unlocking (such as an external mobile power supply), and the button battery cannot be unlocked due to the fact that a key unlocking function is not provided.

During assembly, the battery compartment fixing plate 17, the mounting bracket 8 and the power supply PCB 9 are fixed into a whole through screws, and the whole battery is conveniently pulled out and fixed in a whole group during replacement.

In summary, when the lock is unlocked, the correct password is input, and the lock tongue 401 of the lock tongue assembly 4 is driven by the motor to move and separate from the fixing seat 15 arranged on the box body, so that the lock can be opened.
