Description

Technical Field

[0001] The present invention relates to the technical field of automobile door locks, and in particular to an automobile door lock based on electric control protection. Background Art

[0002] The hidden door lock is an innovative design, in which the door lock can be completely embedded in the car body when not in use, which not only improves the overall aesthetics of the vehicle, but also enhances safety and anti-theft performance. The hidden door is opened and closed by an electric control system, which is easy and efficient to operate. When the door is closed, its surface transitions smoothly with the body, and the existence of the door is almost invisible. This design not only reduces the wind resistance of the vehicle during driving, but also improves the fuel economy of the vehicle.

[0003] A Chinese patent discloses a new type of hidden car exterior door handle assembly (authorization announcement number CN108547523A). This patented technology sets the handle in a hidden car exterior door handle structure inside the base, which can ensure that the door can be opened when the key is normal, and also ensure that the door can be opened using the NFC module and the sensing module when the key is abnormal. During high-speed driving of the vehicle, the hidden door handle reduces wind resistance and fuel consumption compared to the exposed handle, which is beneficial to energy conservation and emission reduction. At the same time, the hidden door handle can well protect the handle, avoid exposure to the outside of the door sheet metal, and avoid erosion by the sun, wind and rain.

[0004] In the traditional car door lock design, when actually using it, the user needs to put his hand through the door handle and pull it to open the car door. However, this action often leads to some problems. During the operation, the user's fingernails or keys carried with them may inadvertently scratch the paint near the car door, thereby damaging the car paint. In addition, the back of the door lock handle is blocked by itself, and dirt easily accumulates in these areas that are not easy to be found and cleaned. Long-term accumulation may cause damage to the door lock or dysfunction. The residual fingerprints on the grip of the door handle may also be used by criminals. Therefore, there are some deficiencies in the design of the car door lock, which need to be improved to enhance the user experience and the effective protection of the car paint. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the door locks in the prior art are not conducive to cleaning dirt and fingerprints, and there are disadvantages that nails may scratch the car paint when pulling. For this reason, we propose a car door lock based on electric control protection.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a car door lock based on electric control protection type, including a mounting shell, two pop-up devices are installed on one side of the mounting shell, a door lock body is installed on the other end of the mounting shell, a holding plate is fixedly connected to one side of the door lock body, a control terminal is fixedly connected to one side of the mounting shell, a drive motor is installed on one side of the control terminal, one side of the drive motor is fixedly connected to the mounting shell, one side of the mounting shell is fixedly connected to an outer shell, and a protective component is installed inside the mounting shell.

[0008] Preferably, a spring is fixedly connected to the top of the slide plate, and the top end of the spring is fixedly connected to the inside of the baffle.

[0009] Preferably, one side of the upper protective plate and the lower protective plate is fixedly connected with a bonding plate, and the bonding plate is made of silicone material.

[0010] Preferably, a sub-velcro is fixedly connected to the top of the extension plate, a main Velcro is provided at the bottom of the cleaning wipe, and the bottom of the main Velcro is fit-connected to the sub-velcro.

[0011] Preferably, a long groove is provided on one side of the lower protective plate, and an elastic rope net is fixedly connected to the inner wall of the long groove.

[0019] Reference Figure 1 - Figure 5As shown, in this embodiment: the protection component includes four rotating shafts 8 fixedly connected to both sides of the inner wall of the mounting shell 1, the inner wall of the rotating shaft 8 is rotatably connected to two rotating rods 9, the middle of the rotating rod 9 is fixedly connected to a cylindrical gear 10, one side of the rotating rod 9 located at the top is fixedly connected to an upper protective plate 11, one side of the other rotating rod 9 is fixedly connected to a lower protective plate 12, one side of the upper protective plate 11 is fixedly connected to a slide plate 13, the surface of the slide plate 13 is slidably connected to a baffle plate 14, the top of the baffle plate 14 is fixedly connected to an extension plate 15, and the top of the extension plate 15 is installed with a cleaning The inner wall of the housing 7 is connected with a transmission tooth 17 through a shaft, and one side of the transmission tooth 17 is meshed with the upper protective plate 11 at the bottom. The output end of the drive motor 6 is meshed with the surface of the cylindrical gear 10 through a gear. The output end of the drive motor 6 is meshed with the transmission tooth 17. When the mounting shell 1 and the door lock body 3 are in the inner wall of the door and are not ejected, the upper protective plate 11 and the lower protective plate 12 are in a merged state, and are connected to the car through the control terminal 5. When the door lock body 3 and the mounting shell 1 are ejected and opened by the ejection device 2, the drive motor 6 is driven to operate. , the cylindrical gear 10 is driven to rotate by meshing the drive motor 6 with the transmission tooth 17, so that the cylindrical gear 10 is driven to rotate, so that the rotating rod 9 follows the cylindrical gear 10 to rotate on the inner wall of the rotating shaft 8, so that the upper protective plate 11 at the top rotates upward, and the lower protective plate 12 at the bottom rotates downward, and is respectively placed at the bottom and top of the horizontal plane between the door lock body 3 and the door, and fits the door surface, so that the upper protective plate 11 and the lower protective plate 12 protect the top and bottom of the door handle pop-up, to prevent the user's nails or keys in the hand from rubbing against the door paint when holding the door lock body 3. The upper protective plate 11 rotates to make the baffle plate 14 and the extension plate 15 close to the holding plate 4, and the microfiber cloth cleaning wipe 16 is used to contact and wipe the holding plate 4, thereby removing the fingerprints remaining on the holding plate 4 when the user holds it, preventing the fingerprints from being illegally used after being copied, and can effectively block and protect the paint near the door handle to prevent the user from scratching the paint during operation, and at the same time clean the holding plate 4, solving the problem that the residual dirt on the back surface of the holding plate 4 is difficult to find and clean, thereby ensuring the cleanliness of the contact surface of the holding plate 4.

[0020] Reference Figure 3As shown, in this embodiment: a spring 18 is fixedly connected to the top of the slide plate 13, and the top of the spring 18 is fixedly connected to the inside of the baffle plate 14. When the extension plate 15 follows the upper protective plate 11 to rotate close to the gripping plate 4, when one end of the extension plate 15 contacts the top surface of the gripping plate 4, the extension plate 15 can fit on one side of the gripping plate 4 to move, and press the baffle plate 14 to slide on the surface of the slide plate 13, so that the baffle plate 14 slightly compresses the spring 18 to accumulate force, and then the spring 18 pushes the baffle plate 14 and the extension plate 15 in the opposite direction to wipe the cleaning wipe 16 close to the surface of the gripping plate 4, ensuring that the cleaning wipe 16 and the gripping wipe 16 are close to each other. The plate 4 is in close contact, and the elastic restoring force of the spring 18 ensures that the cleaning wipe 16 applies constant pressure to the holding plate 4, avoiding the problem of incomplete wiping due to insufficient pressure. The design of the spring 18 also makes the entire wiping action softer, reducing the damage to the surface of the holding plate 4 caused by excessive friction, and through the elastic adjustment of the spring 18, the cleaning wipe 16 always maintains a good contact state with the holding plate 4, thereby ensuring the uniformity and thoroughness of the wiping. This design not only improves the cleaning efficiency, but also extends the service life of the cleaning wipe 16 and reduces the wear of the cleaning wipe 16.

[0021] Reference Figure 2 and Figure 4 As shown, in the present embodiment: one side of the upper protective plate 11 and the lower protective plate 12 are fixedly connected with a bonding plate 19, and the bonding plate 19 is made of silicone. Through the installed bonding plate 19, when the upper protective plate 11 and the lower protective plate 12 are bonded to the paint surface of the vehicle door, the bonding plate 19 contacts the paint surface to form a gap, thereby reducing the direct contact between the paint surface and the upper protective plate 11 and the lower protective plate 12. The bonding plate 19 made of silicone can shrink and deform softly when in contact with the paint surface of the vehicle door, and fits tightly with the paint surface, thereby reducing the friction damage caused by the upper protective plate 11 and the lower protective plate 12 when they are close to the vehicle surface, and further enhancing the protective performance of the upper protective plate 11 and the lower protective plate 12 on the paint surface near the door handle.

[0022] Reference Figure 1 - Figure 5 As shown, in the present embodiment: a sub-Velcro 20 is fixedly connected to the top of the extension plate 15, a mother Velcro 21 is provided at the bottom of the cleaning wipe 16, and the bottom of the mother Velcro 21 is fitly connected to the sub-Velcro 20.

Such a design enables the user to easily remove the cleaning wipe 16, and then conveniently and thoroughly clean the cleaning wipe 16 that has been used for a long time or replace it in time, thereby ensuring the continuous effectiveness and hygiene of the cleaning wipe 16.

[0023] Reference Figure 2 , Figure 3 and Figure 5As shown, in the present embodiment: a long groove 22 is opened on one side of the lower protective plate 12, and an elastic rope net 23 is fixedly connected to the inner wall of the long groove 22. By opening the long groove 22 and arranging the elastic rope net 23 therein, the long groove 22 forms a simple accommodating space. The elastic rope net 23 provides an additional protection measure for the long groove 22, effectively limiting and preventing the accidental falling of the internal items. Such a design enables the interior of the long groove 22 to safely hold various replacement cleaning wipes 16, or some cleaning wipes and other cleaning supplies. This design not only improves the utilization rate of the space, but also greatly facilitates the users, allowing them to easily access the required cleaning supplies at any time.

[0024] Reference Figure 1 , Figure 3 and Figure 5 As shown, in the present embodiment: sealing plates 24 are fixedly connected to both sides of the opposite surfaces of the upper protective plate 11 and the lower protective plate 12, and a long plate 25 is fixedly connected to the inner wall of the mounting shell 1. By setting the long plate 25 and the sealing plate 24, when the upper protective plate 11 and the lower protective plate 12 are rotated vertically, the sealing plate 24 can move with the upper protective plate 11 and the lower protective plate 12, so that the sealing plate 24 is placed on the outside of the long plate 25, thereby effectively filling and sealing one side of the mounting shell 1, improving the sealing performance of the device, and ensuring that the upper protective plate 11 and the lower protective plate 12 are in the external environment, and foreign matter cannot easily enter the interior of the mounting shell 1, thereby avoiding possible blockage and influence on the operation of the internal components of the device.

[0025] Reference Figure 3 As shown, in the present embodiment: the top structure of the extension plate 15 is arc-shaped, and the top surface of the extension plate 15 is adapted to the side structure of the holding plate 4. The contact surfaces of the extension plate 15 and the holding plate 4 are matched to ensure that the cleaning wipe 16 can fit tightly with the holding plate 4, and one side of the holding plate 4 is fully wiped, so that when one end of the extension plate 15 is rotated downward to the top of the holding plate 4, the spring 18 can be squeezed and stored through the arc surface of the holding plate 4, causing the baffle 14 to move slightly on the surface of the slide plate 13 and fit tightly with the surface of the holding plate 4.

[0026] Working principle: when the mounting shell 1 and the door lock body 3 are at the inner wall of the door and are not ejected, the upper protective plate 11 and the lower protective plate 12 are in a merged state, connected to the vehicle through the control terminal 5, and when the door lock body 3 and the mounting shell 1 are ejected and opened by the ejection device 2, the driving motor 6 is driven to operate, and the cylindrical gear 10 is driven to rotate by the meshing connection between the driving motor 6 and the transmission tooth 17, so that the cylindrical gear 10 is driven to rotate, so that the rotating rod 9 follows the cylindrical gear 10 to rotate on the inner wall of the rotating shaft 8, so that the upper protective plate 11 at the top rotates upward, and the lower protective plate 12 at the bottom rotates downward, and is respectively placed at the bottom and top of the horizontal plane of the door lock body 3 and the door, and fits the door surface, so that the upper protective plate 11 and the lower protective plate 12 protect the top and bottom of the door handle from being ejected. The upper protective plate 11 rotates to make the baffle plate 14 and the extension plate 15 close to the gripping plate 4, and the cleaning wipe 16 of the microfiber cloth is brought into contact with the gripping plate 4 for wiping, thereby removing the fingerprints left by the user when the gripping plate 4 is held, and preventing the fingerprints from being illegally used after being copied. The handle can effectively shield and protect the paint near the door handle, and prevent the user from scratching the paint during operation. At the same time, the gripping plate 4 is cleaned, and the problem of residual dirt on the back surface of the gripping plate 4 being difficult to find and clean is solved, and the cleanliness of the contact surface of the gripping plate 4 is ensured. When the extension plate 15 follows the upper protective plate 11 to rotate close to the gripping plate 4, one end of the extension plate 15 contacts the gripping plate 4. When the top surface of the holding plate 4 is touched, the extension plate 15 can fit on one side of the holding plate 4 for movement, and press the baffle plate 14 to slide on the surface of the slide plate 13, so that the baffle plate 14 slightly compresses the spring 18 to store force, and then the spring 18 pushes the baffle plate 14 and the extension plate 15 in the opposite direction to wipe the cleaning wipe 16 close to the surface of the holding plate 4, ensuring that the cleaning wipe 16 is in close contact with the holding plate 4, and the elastic restoring force of the spring 18 ensures that the cleaning wipe 16 applies a constant pressure to the holding plate 4, avoiding the problem of incomplete wiping due to insufficient pressure. The design of the spring 18 also makes the entire wiping action softer, reduces the damage to the surface of the holding plate 4 caused by excessive friction, and through the elastic adjustment of the spring 18, the cleaning wipe 16 is always in contact with the holding plate 4. Maintaining a good contact state ensures uniformity and thoroughness of wiping. This design not only improves cleaning efficiency, but also extends the service life of the cleaning wipe 16 and reduces the wear of the cleaning wipe 16. Through the installed bonding plate 19, when the upper protective plate 11 and the lower protective plate 12 are bonded to the paint surface of the vehicle door, the bonding plate 19 contacts the paint surface to form a gap, thereby reducing the direct contact between the paint surface and the upper protective plate 11 and the lower protective plate 12. The bonding plate 19 made of silicone material can shrink and deform softly when in contact with the paint surface of the vehicle door, and fits tightly with the paint surface, thereby reducing the friction damage caused by the upper protective plate 11 and the lower protective plate 12 when they are close to the vehicle surface, and further enhancing the protective performance of the upper protective plate 11 and the lower protective plate 12 on the paint surface near the door handle.Through the structural optimization of the designed sub-Velcro 20 and the main Velcro 21, the cleaning wipe 16 can be conveniently disassembled from the surface of the extension plate 15. This design allows the user to easily remove the cleaning wipe 16, and then conveniently and thoroughly clean the cleaning wipe 16 that has been used for a long time or replace it in time, thereby ensuring the continued effectiveness and hygiene of the cleaning wipe 16. By opening the long groove 22 and arranging an elastic rope net 23 therein, the long groove 22 forms a simple accommodating space. The elastic rope net 23 provides additional protection for the long groove 22, effectively limiting and preventing the accidental falling of the internal items. This design allows the long groove 22 to safely hold various replacement cleaning wipes 16, or some cleaning wipes and other cleaning supplies. This design not only improves the utilization rate of space, but also greatly facilitates users, allowing them to easily access the cleaning supplies they need at any time. By setting the long plate 25 and the sealing plate 24, when the upper protective plate 11 and the lower protective plate 12 rotate vertically, the sealing plate 24 can move with the upper protective plate 11 and the lower protective plate 12, so that the sealing plate 24 is placed on the outside of the long plate 25, thereby effectively filling and sealing one side of the mounting shell 1, improving the sealing performance of the device, ensuring that foreign matter cannot easily enter the interior of the mounting shell 1 when the upper protective plate 11 and the lower protective plate 12 are in the external environment, thereby avoiding blockage and influence on the operation of the internal components of the device. By matching the contact surfaces of the extension plate 15 and the holding plate 4, it is ensured that the cleaning wipe 16 can fit tightly with the holding plate 4, and one side of the holding plate 4 is fully wiped, so that when one end of the extension plate 15 rotates downward to the top of the holding plate 4, the spring 18 can squeeze and accumulate force through the arc surface of the holding plate 4, causing the baffle 14 to move slightly on the surface of the slide plate 13 and fit tightly with the surface of the holding plate 4.
