Description

Technical Field

[0001] The present invention relates to the technical field of locks, and particularly to an automobile door lock. Background Art

[0002] With the development of social economy, automobiles have become the most important means of transportation for travel. During the process of urban road construction, parking spaces will be planned. When some car owners park their cars, for convenience, they will park in places where parking spaces are not planned. At this time, it is necessary for the traffic management department to conduct investigations. The current investigation methods are to issue tickets or lock the front wheels of the vehicle. The fines vary in different regions. The method of issuing tickets only serves to impose fines, and the method of issuing tickets does not result in fines every time there is illegal parking. The cost of illegal parking is low, and some car owners are always willing to take the risk. For the method of locking the front wheels to prevent the vehicle from moving, it is necessary for the urban management or traffic police department to unlock it later, which will increase the workload of the traffic police department or the urban management. Both methods have certain defects. Summary of the Invention

[0027] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should be the ordinary meanings understood by those skilled in the art to which the present invention belongs.

[0028] Embodiment 1

[0029] As Figure 1 shown, in this embodiment, an automobile door lock is provided, which includes a box body 1, a sliding rod 2, a battery 4, a single-chip microcomputer 5 and two hooks 3. The sliding rod 2 movably penetrates the left and right side walls of the box body 1. One hook 3 is arranged at the right end of the sliding rod 2, and the other hook 3 is arranged on the left side of the box body 1. An electric clamping assembly, a battery 4 and a single-chip microcomputer 5 are arranged in the box body 1. A two-dimensional code is arranged on the outer wall of the box body 1. The battery 4 supplies power to the single-chip microcomputer 5 and the electric clamping assembly. The external controller can transmit signals to the single-chip microcomputer 5 to control the electric clamping assembly to clamp and relax the sliding rod 2. After the external device scans the two-dimensional code to pay the price, it can transmit information to the single-chip microcomputer 5, and the single-chip microcomputer 5 can control the electric clamping assembly to relax the sliding rod 2.

[0030] In this embodiment, through the cooperation of the box body 1, the sliding rod 2, the battery 4, the single-chip microcomputer 5, the electric clamping assembly and the two hooks 3, one hook 3 is fixed to the right end of the sliding rod 2, and the other hook 3 is fixed to the left wall of the box body 1. When the staff locks the car, the external controller controls the electric clamping assembly to make the sliding rod 2 in a relaxed state. At this time, the sliding rod 2 can move relative to the box body 1, and the distance between the two hooks 3 can change. Adjust the distance between the two hooks 3 to a suitable position, hook the two hooks 3 on the two door handles on the same side of the car respectively, and then tighten the two hooks 3 and make the external controller transmit a signal to the single-chip microcomputer 5 to control the electric clamping assembly to clamp and fix the sliding rod 2, so as to lock the two doors on one side of the car. When the driver needs to open the door, after scanning the QR code with the mobile phone to pay the price, the information is transmitted to the single-chip microcomputer 5. The single-chip microcomputer 5 controls the electric clamping assembly to relax the sliding rod 2. At this time, the driver can remove the car door lock, and then the driver needs to return the car door lock to the designated position. In this way, the traffic police department or the urban management department does not need to go to unlock again, reducing the burden on the traffic police department or the urban management department. At the same time, the car owner needs to return the car door lock, increasing the cost of illegal parking for the car owner. In order to reduce the trouble of returning the car door lock, the car owner will consciously abide by the car parking rules. Specifically, a positioning module can be set in the single-chip microcomputer 5. If the driver does not return the car door lock to the designated position within a certain period, additional fines can be imposed, etc.

[0031] In this embodiment, the electric clamping assembly includes a motor 6, a rotating rod 7 and two clamping plates 9. The battery 4 supplies power to the motor 6, and the single-chip microcomputer 5 can control the start and stop of the motor 6. A chute 8 is provided on the inner rear wall of the box body 1, and two sliders are slidably arranged in the chute 8. The two clamping plates 9 are respectively connected to the two sliders, and the two clamping plates 9 are respectively located on the upper and lower sides of the sliding rod 2. The output shaft of the motor 6 is connected to the rotating rod 7, and the rotating rod 7 passes through the two clamping plates 9. The rotating rod 7 has two threads with opposite helix directions, and the two threads are respectively threadedly connected to the two clamping plates 9. When the motor 6 starts, it can drive the two clamping plates 9 to move towards each other or away from each other, and the two clamping plates 9 can simultaneously clamp the top wall and the bottom wall of the sliding rod 2 respectively.

[0032] In this embodiment, the motor 6, the rotating rod 7, the two clamping plates 9 and the chute 8 cooperate to form a ball screw structure. Only by starting the motor 6 can the two clamping plates 9 move towards each other or away from each other, so as to realize the clamping and relaxation of the sliding rod 2. The structure is simple, and the control accuracy of the motor 6 is high.

[0033] In this embodiment, two chutes 8 are provided. Two sliders are connected to each clamping plate 9, and the two sliders on each clamping plate 9 are respectively slidably connected to the two chutes 8.

[0034] Embodiment 2

[0035] AsFigures 2 - 4 As shown in Figures 2 - 4 , in this embodiment, an automobile door lock is provided, which includes a box body 1, a sliding rod 2, a battery 4, a single-chip microcomputer 5 and two hooks 3. The sliding rod 2 movably penetrates the left side wall and the right side wall of the box body 1. One hook 3 is arranged at the right end of the sliding rod 2, and the other hook 3 is arranged on the left side of the box body 1. An electric clamping assembly, a battery 4 and a single-chip microcomputer 5 are arranged inside the box body 1. A two-dimensional code is arranged on the outer wall of the box body 1. The battery 4 supplies power to the single-chip microcomputer 5 and the electric clamping assembly. The external controller can transmit signals to the single-chip microcomputer 5 to control the electric clamping assembly to clamp and relax the sliding rod 2. After the external device scans the two-dimensional code and pays the price, it can transmit information to the single-chip microcomputer 5, and the single-chip microcomputer 5 can control the electric clamping assembly to relax the sliding rod 2.

[0036] In this embodiment, two sliding rods 2 are provided. Both of the two sliding rods 2 movably penetrate the left side wall and the right side wall of the box body 1. One hook 3 is arranged at the right end of one sliding rod 2, and the other hook 3 is arranged at the left end of the other sliding rod 2. The electric clamping assembly can clamp and relax the two sliding rods 2 simultaneously.

[0037] In this embodiment, two sliding rods 2 are provided. Both of the two sliding rods 2 can move relative to the box body 1. One hook 3 is arranged at the right end of one sliding rod 2, and the other hook 3 is arranged at the left end of the other sliding rod 2. During the sliding process of the sliding rod 2, the distance between the two hooks 3 will change. Adjust the distance between the two hooks 3 to a suitable position, hook the two hooks 3 on the two door handles on the same side of the car respectively, and then tighten the two hooks 3 so that the external controller transmits signals to the single-chip microcomputer 5 to control the electric clamping assembly to clamp and fix the two sliding rods 2, thereby locking the two doors on one side of the car. When the driver wants to open the door, after scanning the two-dimensional code with the mobile phone and paying the price, the information is transmitted to the single-chip microcomputer 5, and the single-chip microcomputer 5 controls the electric clamping assembly to relax the two sliding rods 2. At this time, the automobile door lock can be removed, and then the driver needs to return the automobile door lock to the designated position. In this way, the traffic police department or the urban management department does not need to go to unlock again, reducing the burden on the traffic police department or the urban management department. At the same time, the car owner needs to return the automobile door lock, increasing the cost of illegal parking for the car owner. In order to reduce the trouble of returning the automobile door lock, the car owner can independently and actively abide by the rules of car parking. In this embodiment, by setting two sliding rods 2, the adjustable distance between the two hooks 3 becomes longer, and the length occupied when contracted is basically the same as the length occupied by one sliding rod 2.

[0038] Specifically, a positioning module can be set in the single-chip microcomputer 5. If the driver does not return the automobile door lock to the designated position within a certain period, additional fines can be imposed.

[0039] In this embodiment, the electric clamping assembly includes a motor 6, a rotating rod 7, and two clamping groups. The two clamping groups are respectively an upper clamping group and a lower clamping group. Each clamping group has two clamping plates 9. The battery 4 supplies power to the single-chip microcomputer 5 and the motor 6. The single-chip microcomputer 5 can control the start and stop of the motor 6. A chute 8 is provided on the inner rear wall of the box body 1. Four sliders are slidably arranged in the chute 8. The four clamping plates 9 are respectively connected to the four sliders.

[0040] The output shaft of the motor 6 is connected to the rotating rod 7. The rotating rod 7 passes through the four clamping plates 9. The rotating rod 7 has an upper section and a lower section. Both the upper section and the lower section have two threads with opposite helix directions. The two clamping plates 9 in the upper clamping group are respectively located on the upper and lower sides of the upper sliding rod 2. The two clamping plates 9 in the lower clamping group are respectively located on the upper and lower sides of the lower sliding rod 2. The two threads in the upper section are respectively threadedly connected to the two clamping plates 9 in the upper clamping group. The two threads in the lower section are respectively threadedly connected to the two clamping plates 9 in the lower clamping group. When the motor 6 starts, it can drive the two clamping plates 9 in the clamping group to move towards each other or away from each other. When the two clamping plates 9 in the upper clamping group clamp and fix the upper sliding rod 2, the two clamping plates 9 in the lower clamping group clamp and fix the lower sliding rod 2.

[0041] In this embodiment, through the cooperation of the motor 6, the rotating rod 7, the two clamping groups, and the chute 8, two bidirectional lead screw structures are formed. The two clamping groups can simultaneously clamp and relax the two sliding rods 2, and are controlled by one motor 6, which simplifies the structural setting and makes the control system more simple.

[0042] In this embodiment, an infrared emitter 10 and an infrared receiver 11 are provided in the box body 1, and a telescopic unit is provided on the sliding rod 2.

[0043] The infrared emitter 10 is provided on one clamping plate 9, and the infrared receiver 11 is provided on the inner wall of the box body 1. The battery 4 supplies power to the infrared emitter 10 and the infrared receiver 11. When the clamping group clamps the sliding rod 2, the infrared receiver 11 can receive the signal of the infrared emitter 10 and send the information to the single-chip microcomputer 5.

[0044] The telescopic unit includes a first battery, a first single-chip microcomputer, a cylinder 12, and a connecting rod assembly 13. The first battery supplies power to the first single-chip microcomputer and the cylinder 12. The connecting rod assembly 13 is located in front of the hook 3. The output shaft of the cylinder 12 is connected to the connecting rod assembly 13. The connecting rod assembly 13 is connected to the hook 3. When the cylinder 12 starts, it can drive the connecting rod assembly 13 to move backward. A cylinder 12 control button is provided on the sliding rod 2.

[0045] After receiving the information from the infrared receiver 11, the single-chip microcomputer 5 can send a signal to the first single-chip microcomputer, and the first single-chip microcomputer can control the first battery to interrupt the power supply to the cylinder 12.

[0046] Since the hook 3 inside the device can only be adjusted horizontally, and due to the certain thickness of the box body 1, for some vehicle models, it is impossible to hook the two hooks 3 onto the door handle. For example, when the position where the door handle protrudes from the car door is relatively small, when the box body 1 is attached to the car door, the hook 3 cannot be hung on the door handle, resulting in restricted use of the car door lock. To further illustrate the situation where the hook 3 cannot be hung on the door handle, taking the side of the box body 1 attached to the car door as the rear side and the other side as the front side, that is, when the part where the door handle protrudes from the car door is short, at this time, the position of the hook 3 is on the front side of the door handle, and the hook 3 cannot be hung on the door handle.

[0047] In this embodiment, through the cooperation of the infrared emitter 10, the infrared receiver 11 and the telescopic unit, when the staff locks the car, the clamping group does not clamp the sliding rod 2 at this time. The infrared emitter 10 and the infrared receiver 11 are at different heights, and the infrared receiver 11 cannot receive the signal of the infrared emitter 10. The first battery in the telescopic unit supplies power to the cylinder 12. The staff operates the control button of the cylinder 12 to adjust the telescopic state of the cylinder 12, and then adjusts the front-back positions of the connecting rod assembly 13 and the hook 3, so that the hook 3 can move backward and hook on the door handle. After the two hooks 3 are respectively hooked on the two door handles, the two hooks 3 are tightened. At this time, the control motor 6 is started. The motor 6 drives the clamping plate 9 in the clamping group to move. The two clamping groups respectively clamp and fix the two sliding rods 2. At this time, the infrared emitter 10 moves along with the movement of the clamping plate 9. After the clamping plate 9 clamps the sliding rod 2, the infrared receiver 11 receives the signal of the infrared emitter 10 and transmits the information to the single-chip microcomputer 5. The single-chip microcomputer 5 transmits the signal to the first single-chip microcomputer, and the first single-chip microcomputer controls the power supply of the first battery to the cylinder 12 to be interrupted. The cylinder 12 selects a cylinder 12 that does not reset after power-off. In this way, after the electric clamping assembly clamps the sliding rod 2, the horizontal position of the sliding rod 2 is fixed, the front-back position of the hook 3 is fixed, and the hook 3 is also in a tightened state. And because the power supply of the first battery to the cylinder 12 is interrupted, operating the control button of the cylinder 12 cannot control the cylinder 12, and thus cannot adjust the front-back position of the hook 3, realizing the locking of the hook 3, which cannot be changed before the driver scans the QR code to pay. It realizes the linkage of the fixed front-back position and the fixed horizontal position of the hook 3, simplifies the operation of the staff, ensures that the car door lock can be used for various forms of door handles, and improves the adaptability of the car door lock.

[0048] In this embodiment, the cylinder 12 is a multi-stage cylinder. In this embodiment, the sliding rod 2 has a cavity inside, and both the first battery and the first single-chip microcomputer are arranged in the cavity. In this embodiment, the outer wall of the hook 3 is covered with a soft rubber layer.

[0049] In this embodiment, the hook 3 includes a connecting section and a hanging section. The hanging section of the hook 3 on the right side of the box body 1 is in an "S" shape, and the hanging section of the hook 3 on the left side of the box body 1 is symmetrically arranged with the hanging section of the hook 3 on the right side of the box body 1. As Figure 5 shown, when the two door handles are tightened, the lower section of the hanging section is used to tightly fix the proximal ends of the inner walls of the two door handles. As Figure 6 shown, when the door handle is abutted, the upper section of the hanging section is used to abut and fix the distal end of the inner wall of the door handle, so as to achieve various forms of fixation. The link assembly 13 is connected to the connecting section. In this embodiment, the ends of the two door handles close to each other are the proximal ends.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
