Description

Technical Field

[0001] This utility model specifically relates to the field of anti-theft lock cylinder technology, and more specifically to an anti-theft lock cylinder for electric vehicles. Background Technology

[0002] Early electric vehicles often used simple linear hard plate keys and single, double or four-row pin tumbler lock cylinders, which were easily opened by thieves using special lock picking tools or destructive tools, such as reverse guns for cross locks and irregular hooks for U-shaped locks, posing a great security risk.

[0003] With the continuous increase in the number of electric vehicles on the road, the problem of theft has become increasingly prominent. Consumers have higher and higher requirements for the anti-theft performance of electric vehicles, prompting manufacturers to continuously improve lock cylinder technology to meet market demands; people are also paying more attention to property security and are willing to pay for better anti-theft products. This has driven the research and innovation of electric vehicle anti-theft lock cylinder technology to provide more reliable anti-theft protection.

[0004] Traditional lock cylinders typically use pin tumbler or wafer tumbler lock cylinders, which makes the internal structure of the lock cylinder relatively simple and easy to copy. This allows thieves to easily obtain lock-picking tools, increasing the risk of electric vehicle theft.

[0005] A search revealed that Chinese Patent Publication No. CN200910095360.3 discloses an anti-theft lock cylinder, which includes a lock shell and a lock cylinder. The lock cylinder has several rows of pin holes, with a corresponding pin in each pin hole. The lock shell has a sealing bead and a pressure spring. A retaining bead is provided between the pressure spring and the pin. At least one pin has a working groove on its transverse circumferential surface. A locking key is provided between the lock cylinder and the lock shell. The locking key is adapted to the working groove on the pin. A retaining pin is provided in the pin hole and slides along its axial direction. The retaining pin is located between the lock cylinder and the pin and is sleeved with the pin. The end face of the retaining pin facing the locking key has an opening adapted to the locking key and communicating with the working groove on the pin. At least one pin is provided between the retaining bead and the retaining bead. A groove adapted to the steel ball is provided on the adjacent surface of the lock cylinder and the lock shell.

[0006] While the aforementioned patent's magnetic pin design aims to enhance anti-theft performance, magnetic lock cylinders generally suffer from susceptibility to strong magnetic interference. Exposure to a strong external magnetic field can cause the magnetic pins inside the lock cylinder to lose magnetism or become incorrectly magnetized, affecting the normal operation of the lock cylinder and potentially allowing it to be accidentally opened. Prolonged exposure to high temperatures, strong vibrations, or contact with demagnetizing materials can gradually demagnetize the magnetic material within the lock cylinder, leading to lock cylinder failure. When the lock cylinder in the aforementioned patent cannot be opened normally, it requires exposure and destruction, and the damaged lock cylinder cannot be effectively reassembled. Utility Model Content

[0007] The purpose of this utility model is to provide an anti-theft lock cylinder for electric vehicles. In this device, multiple sets of first and second paddles are arranged inside the housing. A second spring is arranged at the bottom of the first and second paddles. When the key is not inserted, the first and second paddles in each set are separated by the second spring, which facilitates locking. When the key is inserted, the first and second teeth on the first and second paddles move along the grooves, thereby effectively moving the notches opened at the top of the first and second paddles to the same axis, thus realizing the descent of the locking pin. The first and second paddles are arranged in an alternating manner inside the housing, which makes the internal structure complex and difficult to be easily copied, thereby improving the anti-theft quality and solving the problems of the above-mentioned background technology.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An anti-theft lock cylinder for electric vehicles includes a first fixed shell; a lock cylinder is installed inside the first fixed shell; the lock cylinder includes a housing; a plurality of symmetrical openings are provided on the side wall of one end of the housing; a first paddle and a second paddle are movably installed in each of the plurality of symmetrical openings; a second spring is provided at the bottom of the first paddle and the second paddle; and a long groove is provided on the first paddle and the second paddle to facilitate the passage of a key.

[0010] The first paddle has a first tooth integrally formed at the top of its long groove; the second paddle has a second tooth integrally formed at the top of its long groove; wherein the length of the first tooth is 1.5 times the length of the second tooth; this makes the structure inside the lock cylinder difficult to replicate, thereby improving the security of the lock cylinder.

[0011] As a further technical solution of this utility model, the insertion end of the key is provided with grooves that respectively cooperate with the first and second paddles; the depth of the grooves is the same as the length of the first and second paddles; in this way, when the key is inserted, the corresponding grooves move the corresponding paddles, thereby moving the first and second paddles.

[0012] As a further technical solution of this utility model, the top of the first and second paddles are provided with notches that cooperate with the locking post; the locking post is located in the rectangular opening at the top of the housing; the top of the locking post contacts the first fixed housing, and the top of the locking post is provided with a first spring and a pressure ball; when the notches at the top of the first and second paddles are on the same axis, the first spring presses the locking post into the notch, thereby separating the first fixed housing and facilitating the rotation of the lock cylinder;

[0013] As a further technical solution of this utility model, a rotating ring is installed inside the end of the housing away from the opening. The rotating ring is installed away from the housing through a snap ring and a rotating block.

[0014] As a further technical solution of this utility model, the rotating block is located between the first fixed shell and the second fixed shell; wherein; the interior of the second fixed shell has the same structure as the interior of the first fixed shell; the top of the first fixed shell and the second fixed shell can be detachably installed by bolts and connecting blocks;

[0015] As a further technical solution of this utility model, the first and second teeth in the long grooves of the first and second paddles are arranged in an alternating manner.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In use, the corresponding first and second paddles are respectively assembled into the openings on the side wall of the housing, and a second spring is installed between the protrusions at the bottom of the first and second paddles. This effectively ensures that one end of the first and second paddles is located in the opening, avoiding the overlap between the two paddles. This makes the internal structure of the housing complex and difficult to replicate.

[0018] 2. In this utility model, the locking pin is placed inside the rectangular opening by the first spring and the pressure ball. Since the notches at the top of the first and second paddles are no longer on the same axis, the locking pin effectively ensures that the housing cannot be rotated.

[0019] 3. In use, the two grooves on the key are inserted into the long slots inside the first and second levers. During insertion, the first and second teeth on the first and second levers move with the grooves, thereby moving the first and second levers to their corresponding positions. This moves the notches at the top of the first and second levers to the same axis. At this time, the first spring and the pressure ball push the locking pin into the notch, separating the locking pin from the first fixed shell. By turning the key, the lock cylinder rotates through the rotating ring, thereby effectively opening the lock. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-10In this embodiment of the utility model, an electric vehicle anti-theft lock cylinder includes a first fixed shell 3; a lock cylinder 7 is installed inside the first fixed shell 3; the lock cylinder 7 includes a housing 70; a plurality of symmetrical openings 77 are provided on the side wall of one end of the housing 70; a first paddle 71 and a second paddle 72 are movably installed in each of the plurality of symmetrical openings 77; a second spring 75 is provided at the bottom of the first paddle 71 and the second paddle 72; a long groove is provided on the first paddle 71 and the second paddle 72 to facilitate the passage of a key 1.

[0033] The first paddle 71 has a first tooth 78 integrally formed on the top of its long groove; the second paddle 72 has a second tooth 79 integrally formed on the top of its long groove; wherein the length of the first tooth 78 is 1.5 times the length of the second tooth 79.

[0034] The key 1 has a groove 2 at its insertion end that mates with the first lever 71 and the second lever 72 respectively; the depth of the groove 2 is the same as the length of the first lever 71 and the second lever 72.

[0035] By adopting the above technical solution, in use, the corresponding first paddle 71 and second paddle 72 are respectively assembled into the opening 77 opened on the side wall of the housing 70, and the second spring 75 is installed between the protrusions at the bottom of the first paddle 71 and the second paddle 72. This effectively ensures that one end of the first paddle 71 and the second paddle 72 is located in the opening 77, avoiding the situation where the two paddles overlap. This makes the internal structure of the housing 70 complex and difficult to replicate.

[0036] In this embodiment, the top of the first lever 71 and the second lever 72 are provided with notches that cooperate with the locking post 74; the locking post 74 is located in the rectangular opening 76 on the top of the housing 70; the top of the locking post 74 is provided with a first spring 73 and a pressure ball;

[0037] In this embodiment, a rotating ring is installed inside the end of the housing 70 away from the end with the opening 77. The rotating ring is installed away from the housing 70 through a snap ring and a rotating block 4.

[0038] By adopting the above technical solution, the locking post 74 is placed inside the rectangular opening 76 by the first spring 73 and the pressure ball. Since the notches at the top of the first paddle 71 and the second paddle 72 are no longer on the same axis, the locking post 74 effectively ensures that the housing 70 cannot be rotated.

[0039] Furthermore, the rotating block 4 is located between the first fixed shell 3 and the second fixed shell 5; wherein the interior of the second fixed shell 5 has the same structure as the interior of the first fixed shell 3; the top of the first fixed shell 3 and the second fixed shell 5 is detachably installed with a connecting block 6 via bolts.

[0040] In this embodiment, the first teeth 78 and the second teeth 79 in the long grooves of the first paddle 71 and the second paddle 72 are arranged in an alternating manner.

[0041] By adopting the above technical solution, when in use, the two grooves 2 on the key 1 are inserted into the long slots inside the first paddle 71 and the second paddle 72. During the insertion process, the first teeth 78 and the second teeth 79 on the first paddle 71 and the second paddle 72 move with the grooves 2, thereby moving the first paddle 71 and the second paddle 72 to the corresponding positions, thereby moving the notches on the top of the first paddle 71 and the second paddle 72 to the same axis. At this time, the first spring 73 and the pressure ball push the locking pin 74 into the notch. At this time, the locking pin 74 is separated from the first fixed shell 3. By rotating the key 1, the lock cylinder 7 rotates the rotating block 4 through the rotating ring, thereby effectively opening the lock.

[0042] The working principle of this utility model is as follows: In use, the corresponding first paddle 71 and second paddle 72 are respectively assembled into the opening 77 opened on the side wall of the housing 70, and the second spring 75 is installed between the protrusions at the bottom of the first paddle 71 and the second paddle 72. This effectively ensures that one end of the first paddle 71 and the second paddle 72 is located in the opening 77, avoiding the situation where the two paddles overlap. This makes the internal structure of the housing 70 complex and difficult to replicate.

[0043] The locking pin 74 is placed inside the rectangular opening 76 by the first spring 73 and the pressure ball. Since the notches at the top of the first lever 71 and the second lever 72 are no longer on the same axis, the locking pin 74 effectively ensures that the housing 70 cannot be rotated.

[0044] In use, the two grooves 2 on the key 1 are inserted into the long slots inside the first lever 71 and the second lever 72. During the insertion process, the first teeth 78 and the second teeth 79 on the first lever 71 and the second lever 72 move with the grooves 2, thereby moving the first lever 71 and the second lever 72 to the corresponding positions, thus moving the notches on the top of the first lever 71 and the second lever 72 to the same axis. At this time, the first spring 73 and the pressure ball push the locking pin 74 into the notch. At this time, the locking pin 74 separates from the first fixed shell 3. By turning the key 1, the lock cylinder 7 rotates the rotating block 4 through the rotating ring, thereby effectively opening the lock.
