The invention provides a cabinet anti-theft door lock system and a cabinet. The door panel body of the anti-theft door lock system is provided with a handwheel mechanism, a key lock and a transmission mechanism; A plurality of anti-pry bolts are set on one side of the frame, so that when the main body of the door panel is closed, its surroundings and the door frame of the cabinet are interlocked by the anti-pry bolts, and the left and right movement of the anti-pry bolts on the sliding frame is controlled by the hand wheel mechanism to realize the main body of the door panel. The lock state with the door frame of the cabinet is released; at the same time, the lock of the hand wheel mechanism is realized through the key lock; even if the key lock is damaged, the hand wheel is still locked, and the main body of the door panel cannot be opened. When it is opened, the cabinet door can be opened through the handwheel mechanism. The cabinet anti-theft door lock system and the cabinet provided by the present invention have strong anti-destructive power, and the anti-theft level can be greatly improved, which can better protect the internal equipment and batteries of the cabinet, prevent Man-made vandalism and theft.

The embodiment of the present invention discloses an anti-theft system and method for a connected car. The anti-theft system includes: a wireless communication connected car and a mobile terminal; the position tracking module of the connected car is used to acquire The first running track data set of the mobile terminal; synchronously, the terminal positioning module of the mobile terminal is used to obtain the second running track data set of itself according to the pre-stored random interval array; The module is used to control the start of the Internet of Vehicles vehicle if it detects that the accuracy deviation result of the first running track data set and the second running track data set is within a set range when receiving the remote start authentication instruction. The anti-theft system and method of the connected car provided by the embodiments of the present invention reduce the risk of theft of the connected car.

The invention overcomes defects of the existing technology, and provides a locking lock with a built-in motor. Grooves or protrusions are arranged on four sides of the locking lock with the built-in motor, so that anti-theft performance of a key is further enhanced; with the built-in motor installed, a self-locking structure is achieved, and an anti-theft level is improved; and the lock cannot beopened internally without the key, and thus has high safety performance. According to the technical scheme, the locking lock with the built-in motor comprises the key, a motor assembly, a locking structure and a lock body, wherein the motor assembly and the locking structure are installed inside the lock body, the motor assembly is used to lock or unlock a handle, and the locking structure can only be unlocked through a matched key and prevent the lock body from being unlocked through rotating an internal handle. The locking lock with the built-in motor can be widely applied to the field of lock bodies.

Provided is a lock cylinder with limited posts. The invention relates to a lock cylinder, particularly to a lock cylinder with limited posts. With the lock cylinder, problems that the A-level anti-theft lock has a poor burglary prevention performance and the B-level anti-theft lock with the high cost is not suitable for popularization and application can be solved. A plurality of first through hole are successively formed in a lower hole wall of a key hole of an inner lock cylinder from left to right side by side; a plurality of second through holes are successively formed in a lower hole wall of an insertion hole of an outer lock cylinder from left to right side by side; and the multiple first through holes and the multiple second through holes are connected in a one-to-one correspondence mode. An upper column body is arranged in each first through hole; a lower column body, a spring, and a sealing bead are successively arranged at each second through hole from top to bottom; and one limiting post is arranged in each spring. A distance H between an upper end surface of each limited post and a lower end surface of each corresponding lower column body is H; a depth of each first through hole is D; a height of each upper column body is L; and the L is larger than the H and the H is larger than the L minus D. The lock cylinder is used for burglary prevention.

The invention provides an anti-theft system and an anti-theft method for vehicles, and relates to the field of vehicle safety. The anti-theft system includes: a first controller, configured to generate an authentication request instruction after receiving an unlocking request; a second controller, connected to the first controller, for communicating with the authentication request instruction after receiving the authentication request instruction. The first controller performs authentication interaction, and generates an unlocking instruction after the authentication interaction is passed; and an anti-theft lock, set in the shift mechanism of the vehicle, connected with the second controller, and used for unlocking according to the command to release the N gear in the shift mechanism to unlock the vehicle. The solution of the invention can effectively prevent the new energy electric vehicle from being stolen.

A mechanical combination lock with electronic input is formed by connecting an electronic combination system to a mechanical combination system. The electronic combination system comprises an electronic input device, a control circuit, a drive circuit, a motor (6), and a power supply (5) that are connected in sequence. The mechanical combination system comprises a motor shaft gear (8), a transmission gear (12), a combination member, a limiting and connecting member, a knob (17), a knob shaft (20), and an unlocking device (15). Output of the electronic input device is connected to the control circuit. Output of the control circuit is connected to the drive circuit. Output of the drive circuit is connected to the motor (6). The motor shaft gear (8) is connected to a motor output shaft (9), and the motor shaft gear (8) is connected to and drives the combination member through the transmission gear (12); or, the combination member is directly mounted on the motor output shaft (9), and the limiting and connecting member has one end flexibly connected to the unlocking device (15) and the other end gap-fits the combination member. The knob shaft (20), the knob (17), the unlocking device (15) are components for connecting and fixing. The mechanical combination lock with electronic input has advantages of both a mechanical combination lock and an electronic combination lock, and is convenient, secure, reliable, abundant in combinations, and high in security level.
