Among them, the automobile manufacturing industry increased by 13.1%. In 2023, my country's automobile production and sales will reach 30.161 million and 30.094 million respectively, up 11.6% and 12% year-on-year respectively, of which automobile exports will reach 4.91 million, up 58% year-on-year. The output of new energy vehicles will reach 9.443 million, up 30.3% over the previous year.

[0003] The application number is CN202220749134.3, which discloses a car hood lock. The technical solution key points include a first lock body assembly and a second lock hook assembly. The first lock body assembly is provided with a lower lock body, and the lower lock body is provided with a first connecting center hole, a second connecting center hole, a guide arc surface, a locking mouth, and a rectangular mounting hole. The first lock body assembly is provided with an upper lock body, and the upper lock body is provided with a rectangular mounting hole, a support plate cable groove, a support plate cable hole, an opening pull plate mouth, a locking mouth, a guide arc surface, a limiting support plate, a first connecting center hole, and a second connecting center hole. A middle lock body is provided in the first lock body assembly, and a first annular groove, a torsion spring slot, a second annular groove, a torsion spring slot, a guide arc surface, a locking mouth, a buffer block, a first connecting center hole, and a circular boss of the center hole are provided in the middle lock body. The beneficial effect of the utility model is that the left and right dimensions and the upper and lower dimensions of the lock are large, and no matter whether the hood is deformed or falls, it can be stably, firmly and reliably locked and opened.

[0004] Although the above-mentioned utility model is provided with a first connecting center hole, a second connecting center hole, a guide arc surface, a locking mouth, and a rectangular mounting hole, the first lock body assembly is provided with an upper lock body, and the upper lock body is provided with a rectangular mounting hole, a support plate cable groove, a support plate cable hole, an opening pull plate mouth, a locking mouth, a guide arc surface, a limiting support plate, a first connecting center hole, and a second connecting center hole, and the first lock body assembly is provided with a middle lock body, and the middle lock body is provided with a first annular groove, a torsion spring groove, a second annular groove, a torsion spring groove, a guide arc surface, a locking mouth, a buffer block, a first connecting center hole, and a circular boss of the center hole, thereby achieving a large left and right size range and an upper and lower size range of the lock, regardless of whether the hood is deformed or fallen, it can be stably, firmly and reliably locked and opened, but there is a disadvantage that when the middle device opens the hood, the opening may fail due to the jamming of the internal restraint control system.

[0005] Therefore, it is necessary to add a fault-proof unlocking component to the lock body assembly in the device, so that when the internal lock body assembly control system fails, manual unlocking can be performed through this component to avoid the situation where the hood cannot be opened. The double unlocking method can better ensure the smooth opening of the hood. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 - Figure 4 As shown, the utility model is a car hood lock, comprising a shell assembly 1 and a lock body assembly 2, wherein the lock body assembly 2 is installed inside the shell assembly 1, a fault-proof unlocking assembly 3 is installed outside the lock body assembly 2, and a reinforcement assembly 4 is installed on the top.

[0027] By adding a fault-proof unlocking component 3 to the lock body component 2 in the device, when the control system of the internal lock body component 2 fails, manual unlocking can be performed through this component to avoid the situation where the hood cannot be opened. The double unlocking method can better ensure the smooth opening of the hood.

[0028] The housing assembly 1 comprises a mounting shell 101 , mounting plates 102 are mounted on both sides of the mounting shell 101 , a locking groove 104 is provided at the top in the middle thereof, and a reinforcement hole 103 is provided in the middle of the mounting plate 102 .

[0029] The lock body assembly 2 includes a lock plate 1 201, a lock plate 202 is installed on the other side of the lock plate 1 201, and a tension spring 203 is installed at the bottom thereof, a control tension motor 204 is installed in the middle of the tension spring 203, a rotating shaft (205) is installed in the middle of the lock plate 202 and the lock plate 1 201, and a return spring 206 is installed at the end thereof.

[0030] The fault-proof unlocking component 3 includes a manual adjustment plate 301, which is installed inside the slide groove 302 and has a sliding block 303 installed inside. Through the connection between the sliding block 303 and the manual adjustment plate 301, when the internal control stretching motor 204 is out of control, automatic opening cannot be achieved at this time, and manual unlocking is achieved by pushing the manual adjustment plate 301 upwards.

[0031] The reinforcement component 4 includes a clamping plate 401, a reinforcement block 402 is installed in the middle of the clamping plate 401, and a control rod 403 is installed on one side of the reinforcement block 402. By adding the reinforcement component 4 on the basis of the lock body component 2 of the device, the locking reinforcement effect can be enhanced and guaranteed through the internal reinforcement component 4 while locking. The magnetic strip arranged in the reinforcement component 4 can provide a certain suction fixing effect through the lock hook made of steel.

[0032] The reinforcement block 402 includes a cavity 4021, a longer tension spring 4022 is installed at the bottom of the opening of the cavity 4021, a flexible magnetic strip 4023 is installed at the end of the longer tension spring 4022, and a steel wire pull rope 4024 is installed at the end of the flexible magnetic strip 4023. By setting the steel wire pull rope 4024 at the central control at the front end of the vehicle body, when it needs to be opened, the control can be opened, and the steel wire pull rope 4024 is used to restrain the inside, so that after the flexible magnetic strip 4023 is pulled out, the magnetic attraction relationship with the lock buckle can be disconnected, thereby achieving the purpose of unlocking.

[0033] When using this device, when unlocking is required, first pull up the pull switch of the steel wire rope 4024 set in the center console of the car, and control the internal steel wire rope 4024 to restrain it, so that the flexible magnetic strip 4023 can be pulled out, and the magnetic attraction relationship with the lock buckle can be disconnected, and then the lock plate 201 is controlled by controlling the stretching motor 204 to open rearwards under the positioning of the rotating shaft 205, so that the internal lock buckle overflows. When the internal control stretching motor 204 is out of control, automatic opening cannot be achieved at this time, and manual unlocking is achieved by toggling the manual adjustment plate 301 upwards.
