Description

Technical Field

[0001] The present invention belongs to the technical field of automobile security and anti-theft. More specifically, the present invention relates to an automobile anti-theft device acting on a brake locking system. The present invention also relates to a method for releasing and activating the anti-theft device. Background Art

[0002] New energy vehicles have a simple design structure. They do not have the drive shaft of traditional fuel vehicles, nor do they have mechanical shifters, but the wheel braking system is currently a standard configuration for all vehicles. In particular, most of the current mainstream new energy vehicles use integrated transmissions, with the drive motor directly connected to the power wheel. The implementation of anti-theft devices on such vehicles often requires the modification of the shifting system or transmission mechanism, or the addition of a steering lock, which will greatly increase development costs and vehicle costs.

[0003] In the existing national standards, the locking systems combined with the car starting system to form an anti-theft device include: a) steering mechanism locking system, b) transmission system locking system, and c) shift mechanism locking system. The defects of the existing technology: Regarding the anti-theft of the locking system, it is usually necessary to add an additional locking mechanism or require the car to meet a fixed configuration, which increases the complexity of the vehicle structure, leads to an increase in the cost of parts and the manufacturing cost of the whole vehicle, and reduces the economic efficiency of maintenance. For example:

[0004] a) Steering mechanism locking system, which requires adding a steering column lock to the steering column of the car;

[0005] b) Transmission locking system, which requires the vehicle to be equipped with a mechanical gearbox with a locking rod mechanism or a transmission shaft with a transmission shaft lock or differential lock installed;

[0006] c) Shift mechanism locking system, usually refers to the manual transmission's shift mechanism equipped with a lock rod or adding an electromagnetic lock and related controller to the shift mechanism.

[0007] The State Administration for Market Regulation and the National Standardization Administration issued the national standard "Automobile Anti-theft Device (GB15740-2024)" on September 29, 2024, which will be implemented on January 1, 2026. The definition of automobile anti-theft device is a device consisting of a vehicle power starting system and at least one locking system. On the basis of the three types of locking systems defined in the original standard, namely a), b), and c), this standard adds a new type of locking system, namely: d), brake locking system.

[0008] However, in the prior art, there is no mature technical solution for the automobile anti-theft device combined with the brake locking system added by the new standard.

[0009] The following search results were obtained by searching the existing public technical literature using keywords such as "automobile (or vehicle); brake; lock; system; anti-theft; device":

[0010] 1. Chinese patent document: "Vehicle anti-theft system, method and vehicle", patent (application) number: 202311764400.5; the technical solution recorded is:

[0011] “The vehicle anti-theft system includes: an unlocking module, which is used to send an unlocking request; a body controller, which is used to perform encryption authentication with the unlocking module, and when the encryption authentication with the unlocking module is passed, it is used to perform encryption authentication with the power controller and the brake controller; the power controller is used to unlock the power mechanism when the encryption authentication with the body controller is passed, so as to realize the power output of the vehicle through the power mechanism; the brake controller is used to unlock the brake mechanism when the encryption authentication with the body controller is passed, so as to realize the parking control and shift control of the vehicle through the brake mechanism”;

[0012] The technical effects recorded are:

[0013] "Through interactive control between components, combined anti-theft measures from two aspects, namely power source and parking and shift control, are achieved, thus improving the anti-theft efficiency of the vehicle."

[0014] 2. Chinese patent document: "A lockable anti-theft brake pedal structure and automobile", patent (application) number: 202323057503.6; the technical solution recorded is:

[0015] "A lockable anti-theft brake pedal structure and a vehicle, comprising: a screw, rotatably arranged on a pedal bracket, one end of which is connected to a driving assembly; a pawl, which is screwed on the screw; a guide rod, which is arranged on the pedal bracket, and the pawl is sleeved on the guide rod; a ratchet, which is arranged on a brake pedal arm; the driving assembly drives the screw to rotate, so that the pawl moves along the length direction of the screw, and when the pawl fits with the ratchet, the brake pedal arm enters a locked state";

[0016] The technical effects recorded are:

[0017] "Based on the design of the original car anti-theft system, an anti-theft structure for the brake pedal has been added. The brake pedal is locked so that it cannot move back and forth, which prevents intruders from starting the vehicle and also prevents intruders from successfully driving away the vehicle, thereby adding an extra layer of protection for vehicle safety."

[0018] However, the technical solutions recorded in the above technical documents and the related technical solutions currently in public application have not actually been able to solve the problem and defect of "there is no mature technical solution for the automobile anti-theft device combined with the brake locking system" existing in the prior art. Summary of the invention
