Technical Field
[0001] This invention relates to the field of automotive door lock technology, specifically a high-strength, high-security automotive door lock structure. Background Technology
[0002] With the advancement of technology, the automotive industry is also developing rapidly. In order to protect the safety of car doors, high-strength safety door locks need to be installed, which can not only provide safety but also facilitate passenger operation. The trunk of a car is not only a space for storing items, but also a safe exit for escape in emergency situations. The trunk door lock also plays an important role.
[0003] Traditional car trunk door locks lack proper lubrication components, requiring regular manual lubrication and maintenance. However, few people regularly lubricate the lock's internal components, leading to reduced flexibility after prolonged use. This can severely impact subsequent locking and unlocking control, and even cause the drive motor to overload and burn out. Furthermore, since most door locks are motor-driven, a power outage can render the lock unable to open, jeopardizing passenger safety. Additionally, the locks are typically detachably installed directly onto the door, making position adjustments difficult. This can result in installation discrepancies for different car models, affecting both the lock's performance and subsequent door opening and closing. Summary of the Invention

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0038] like Figure 1 , Figure 2 , Figure 6 , Figure 10 and Figure 11 As shown, the high-strength safety car door lock structure of the present invention includes a lock plate 1, a locking mechanism 2 installed on the lock plate 1, a lubrication mechanism 3 installed on the lock plate 1, a control mechanism 4 installed on the lubrication mechanism 3, a fixing mechanism 5 installed on the lock plate 1, an adjustment mechanism 6 installed on the fixing mechanism 5, and a limit mechanism 7 installed on the locking mechanism 2.
[0039] Specifically, such as Figure 1 , Figure 4 and Figure 5As shown, the locking mechanism 2 includes a fixed shaft 202. Two fixed shafts 202 are vertically fixedly connected to one side of the locking plate 1. A latch 205 with a "C"-shaped structure is rotatably connected to one of the fixed shafts 202 via a torsion spring 206. A buckle 208 with an "L"-shaped structure is rotatably connected to the other fixed shaft 202. A connecting block 211 is fixedly connected to the locking plate 1. A return spring 209 is connected between the connecting block 211 and the buckle 208. One bottom end of the buckle 208 is located at the latch 205. On one side, a slot 204 is provided at the bottom centerline of the locking plate 1. An electromagnet 207 is detachably connected to one side of the locking plate 1. The output shaft of the electromagnet 207 is located on one side of the bottom of the latch 208. A cover plate 201 is installed on one side of the locking plate 1. The cover plate 201 is located on one side of the latch 205, the latch 208, and the electromagnet 207. The installation of the fixed shaft 202 facilitates the installation of the latch 205 and the latch 208. The slot 204 facilitates the insertion of the pin on the vehicle, and the pin abuts against the latch 205. Releasing from the spring force of the torsion spring 206, one end of the latch 205 abuts against the bottom of the buckle 208. The buckle 208 then releases the spring force of the return spring 209, causing the latch 205 to rotate into position, facilitating engagement with the pin. The buckle 208 then resets under the resistance of the return spring 209, and its bottom engages with one end of the latch 205, preventing the latch 205 from rotating. This achieves locking and closing of the pin, thus closing the door. The solenoid valve, when energized, is in a contracted state. By controlling the solenoid... When the electromagnet 207 is energized, it abuts against the latch 208, causing the latch 208 to rotate free from the elastic force of the return spring 209. The latch 208 separates from the lock 205, and the lock 205 resets under the action of the torsion spring 206, thereby pushing out the pin to facilitate opening the door. In the event of an accident, the circuit of the electromagnet 207 is cut off, and the electromagnet 207 will reset and push out under the constraint of no electricity, thereby abutting against the latch 208 and unlocking the lock 205 for emergency rescue.
[0040] Specifically, such as Figure 5 As shown, two limiting shafts 203 are vertically connected to the locking plate 1. One limiting shaft 203 is located at the bottom of the latch 205, and the other limiting shaft 203 is located on one side of the bottom of the buckle 208. A pull rod 210 is fixedly connected to the top of the buckle 208. The installation of the limiting shaft 203 facilitates the contact between the latch 205 and the buckle 208 when they rotate, thus limiting the rotation and preventing excessive rotation from affecting the opening and closing of the lock. The installation of the pull rod 210 facilitates connection with an external cable to achieve manual drive control of the buckle 208.
[0041] Specifically, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the lubrication mechanism 3 includes an oil reservoir 301. The oil reservoir 301 is detachably connected to one side of the locking plate 1. A through hole 306 is provided at the bottom of one side of the oil reservoir 301. Two vertically distributed conveying grooves 303 are provided inside the locking plate 1. A guide groove 302 is provided inside the locking plate 1. One end of the guide groove 302 communicates with the connection point of the two conveying grooves 303, and the other end of the guide groove 302 communicates with the through hole 306. An "L"-shaped lubrication groove 304 is provided inside the two fixed shafts 202. The bottom of the lubrication groove 304 communicates with the conveying groove 303. 4. One end of the top extends to the outside of the fixed shaft 202. The installation of the oil storage tank 301 facilitates the storage of lubricating oil. The through hole 306 allows the lubricating oil to be introduced into the guide groove 302 and the conveying groove 303. The opening of the lubrication groove 304 on the inner side of the two fixed shafts 202 allows the lubricating oil inside the conveying groove 303 to enter the lubrication groove 304 and be discharged to the outside of the fixed shaft 202 through the lubrication groove 304. This makes the locking buckle 205 and the snap buckle 208 rotate more smoothly and facilitates subsequent opening and closing control.
[0042] Specifically, such as Figure 8 and Figure 9 As shown, a top cover 305 is threadedly connected to the center of the top of the oil reservoir 301. One end of the top of the lubrication groove 304 has a certain slope. The opening and closing of the top cover 305 facilitates the closing protection of the oil reservoir 301 and the injection of oil. The slope design at one end of the top of the lubrication groove 304 allows the oil on the fixed shaft 202 to be better discharged for lubrication.
[0043] Specifically, such as Figure 5 , Figure 8 , Figure 9 and Figure 10As shown, the control mechanism 4 includes a rubber block 406. The rubber block 406 is slidably connected to the inner bottom of the oil tank 301. The rubber block 406 has a "T" shape, and its bottom extends to the outer bottom of the oil tank 301. A connecting hole 405 is provided on the rubber block 406. A fixing block 403 is fixedly connected inside the oil tank 301. A contact spring 404 connects the fixing block 403 and the top of the rubber block 406. The bottom of the rubber block 406 is located at the top of the latch 205. The control mechanism 4 is activated by the fixing block 403. The installation facilitates the connection of the abutment spring 404. Under the abutment of the abutment spring 404, the rubber block 406 extends to the outside of the oil reservoir 301. The connecting hole 405 on the rubber block 406 communicates with the through hole 306, allowing lubricating oil to be discharged for lubrication. When the latch 205 is rotated to lock, the rubber block 406 is abutted and retracted, and the rubber block 406 is freed from the elastic force of the abutment spring 404. The rubber block 406 blocks the through hole 306, preventing lubricating oil from being discharged and reducing continuous outflow and waste.
[0044] Specifically, such as Figure 8 and Figure 10 As shown, a top rod 401 is fixedly connected to the bottom of the rubber block 406, and a guide wheel 402 is rotatably connected to the bottom of the top rod 401. The guide wheel 402 is located on the top side of the latch 205. The installation of the top rod 401 facilitates the connection of the guide wheel 402, thereby enabling the latch 205 to smoothly control the contact between the top rod 401 and the rubber block 406 when it rotates.
[0045] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the fixing mechanism 5 includes a fixing seat 501. The fixing seat 501 is installed on the top of one side of the cover plate 201. The fixing seat 501 has a U-shaped structure. The fixing seat 501 has movable grooves 503 at both ends. A fixing sleeve 504 is slidably connected inside the movable groove 503. Both the fixing sleeve 504 and the movable groove 503 have a cross-shaped structure. The installation of the fixing seat 501 facilitates the connection of the fixing sleeve 504, thereby making it easy to fix the fixing seat 501 with bolts. The opening of the movable groove 503 facilitates the sliding of the fixing sleeve 504, thereby realizing the position adjustment of the fixing sleeve 504 and the externally connected screw 603, which facilitates the position adjustment of the connection between the locking plate 1 and the cover plate 201, and achieves better locking operation.
[0046] Specifically, such as Figure 2 and Figure 3As shown, a plurality of positioning pins 502 are vertically connected to the top side of the fixed base 501, and a toothed ring 505 is installed at the bottom edge of the fixed sleeve 504. The toothed ring 505 abuts against the bottom side of the inside of the movable groove 503. The installation of the positioning pins 502 makes the fixed base 501 stable and not easy to loosen after installation. Furthermore, the installation of the toothed ring 505 ensures that after the fixed sleeve 504 is tightened by bolts, the toothed ring 505 at the bottom of the fixed sleeve 504 abuts tightly against the inside of the movable groove 503 and will not slide, thus making the fixed base 501 firmly installed.
[0047] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the adjustment mechanism 6 includes guide plates 601. Multiple guide plates 601 are fixedly connected to the side wall of the cover plate 201. Multiple positioning grooves 602 are provided on the side wall of the fixing seat 501. The fixing seat 501 is slidably connected to the multiple guide plates 601 through the multiple positioning grooves 602. Multiple equally spaced screws 603 are threaded onto the fixing seat 501. The screws 603 extend into the positioning grooves 602 and abut against the side wall of the guide plates 601. Through the installation of the multiple guide plates 601, the fixing seat 501 can be vertically slidably adjusted in position with the guide plates 601 in cooperation with the positioning grooves 602. Furthermore, by tightening the screws 603, the screws 603 abut against and limit the guide plates 601, making the fixing seat 501 stable in installation. This facilitates the adjustment of the height of the locking plate 1 and the cover plate 201 during installation, and achieves better locking with the external pin.
[0048] Specifically, such as Figure 4 As shown, the outer sides of the multiple guide plates 601 are respectively provided with fixing grooves 604. The sidewalls of the fixing grooves 604 have a toothed structure. The opening of the fixing grooves 604 facilitates the tight contact and limiting of the screw 603, and plays a guiding and anti-slip role. At the same time, the opening of the toothed structure ensures that the screw 603 is in tight contact with the fixing grooves 604 and will not slide.
[0049] Specifically, such as Figure 1 , Figure 4 , Figure 11 and Figure 12As shown, the limiting mechanism 7 includes toothed plates 701. Symmetrical toothed plates 701 are installed on the inner top of the cover plate 201. One side of each of the two toothed plates 701 extends to the outer side of the cover plate 201. Pressure plates 704 are vertically connected to opposite sides of the two toothed plates 701. The opposite ends of the two pressure plates 704 have an arc-shaped structure. A drive plate 703 is installed at the center line inside the cover plate 201. The drive plate 703 is slidably connected to the inside of the cover plate 201 via a compression spring 707. The bottom of the drive plate 703 extends to the inner side of the slot 204. Symmetrically distributed drive grooves 706 are provided on both sides of the top of the drive plate 703. The opposite ends of the two pressure plates 704 extend into the two drive grooves 706 respectively. The fixed base 5... 01. Racks 702 are installed on the inner sides of both ends. The racks 702 are located on one side of the toothed plate 701. Through the abutment of the compression spring 707, the drive plate 703 extends into the slot 204, and the two pressure plates 704 extend into the drive groove 706, thereby causing the toothed plate 701 to retract and allowing the fixed seat 501 to move smoothly. When the latch 205 is rotated to lock, the pin abuts against the drive plate 703, causing the drive plate 703 to drive the drive groove 706 to symmetrically abut against the toothed plate 701. The toothed plate 701 is abutted and slides out to abut against the racks 702, thereby limiting the fixed seat 501 and making the fixed seat 501 installed stably and without loosening.
[0050] Specifically, such as Figure 11 and Figure 12 As shown, the bottom of the drive plate 703 has an arc-shaped structure, and one end of the pressure plate 704 extends into the interior of the toothed plate 701. A buffer spring 705 is connected between the pressure plate 704 and the interior of the toothed plate 701. The pressure plate 704 is slidably connected to the interior of the toothed plate 701 through the buffer spring 705. The installation of the buffer spring 705 allows the pressure plate 704 to slide with the interior of the toothed plate 701. After the toothed plate 701 and the rack 702 are in close contact, the pressure plate 704 can continue to slide, thereby allowing the drive plate 703 to slide into place. This facilitates the engagement and locking of the pin with the latch 205, and the pin smoothly drives and controls the drive plate 703.
[0051] In use, this invention first facilitates the installation of the locking buckle 205 and the latch 208 by fixing the shaft 202. The slot 204 facilitates the insertion of the pin on the vehicle, and the pin abuts against the locking buckle 205. The locking buckle 205 then rotates free from the spring force of the torsion spring 206. One end of the locking buckle 205 abuts against the bottom of the latch 208, and the latch 208 rotates free from the spring force of the return spring 209. This allows the locking buckle 205 to rotate into position, facilitating the engagement of the pin. The latch 208 then resets under the resistance of the return spring 209, and the bottom of the latch 208 engages with one end of the locking buckle 205, preventing the locking buckle 205 from rotating. This achieves the locking and locking of the pin, closing the vehicle door. The solenoid valve is in a retracted state when energized, and the electromagnet 20... 7. When powered on, electromagnet 207 abuts against latch 208, causing latch 208 to rotate free from the spring force of return spring 209. Latch 208 separates from latch 205, and latch 205 resets under the action of torsion spring 206, thus pushing out the pin to facilitate door opening. In case of an accident, the circuit of electromagnet 207 is cut off, and electromagnet 207 will reset and push out under the constraint of no power, thus abutting latch 208 and unlocking latch 205 for emergency rescue. The installation of limit shaft 203 facilitates the contact between latch 205 and latch 208 during rotation, acting as a limit to prevent excessive rotation from affecting the locking and unlocking operation. The installation of pull rod 210 facilitates connection with external cable, enabling manual locking of latch 205. The 08 drive control, through the installation of the oil reservoir 301, facilitates the storage of lubricating oil. The through-hole 306 allows lubricating oil to be introduced into the guide groove 302 and the conveying groove 303. The opening of the lubrication grooves 304 on the inner sides of the two fixed shafts 202 allows lubricating oil from the conveying groove 303 to enter the lubrication groove 304, and then outwards to the outside of the fixed shaft 202, making the rotation of the latch 205 and the buckle 208 smoother and facilitating subsequent opening and closing control. The opening and closing of the top cover 305 facilitates the closing protection of the oil reservoir 301 and the injection of oil. The sloping design at one end of the top of the lubrication groove 304 allows for better drainage and lubrication of the oil on the fixed shaft 202. The installation of the fixing block 403 facilitates the engagement of the contact spring 4. 04 Connection: Under the resistance of the spring 404, the rubber block 406 extends to the outside of the oil reservoir 301. The connecting hole 405 on the rubber block 406 communicates with the through hole 306, allowing lubricating oil to be discharged for lubrication. When the latch 205 is rotated to lock, the rubber block 406 is retracted by the resistance, releasing the elastic force of the spring 404. The rubber block 406 blocks the through hole 306, preventing lubricating oil from being discharged and reducing waste caused by continuous outflow. The installation of the push rod 401 facilitates the connection to the guide wheel 402, allowing the latch 205 to smoothly control the contact between the push rod 401 and the rubber block 406 when rotating. The installation of the fixing seat 501 facilitates the connection to the fixing sleeve 504, making it easy to fix the fixing seat 501 with bolts.The opening of the movable groove 503 facilitates the sliding of the fixed sleeve 504, thereby enabling position adjustment of the fixed sleeve 504 and the externally connected screw 603. This facilitates position adjustment of the connection between the locking plate 1 and the cover plate 201, achieving better locking operation. The installation of the positioning pin 502 ensures that the fixed seat 501 is stable and not easily loosened after installation. Furthermore, the installation of the toothed ring 505 ensures that after the fixed sleeve 504 is bolted, the toothed ring 505 at the bottom of the fixed sleeve 504 is in tight contact with the inside of the movable groove 503, preventing slippage. The movement ensures the fixed base 501 is securely installed. Through the installation of multiple guide plates 601, the fixed base 501, in cooperation with the positioning groove 602, can vertically slide and adjust its position with the guide plates 601. Furthermore, by tightening the screw 603, the screw 603 abuts against and limits the guide plate 601, ensuring stable installation of the fixed base 501. This facilitates height adjustment during the installation of the locking plate 1 and the cover plate 201, achieving better engagement and locking with the external pin. The opening of the fixing groove 604 facilitates tight contact and limiting of the screw 603. It also serves as a guide and prevents slippage. Simultaneously, the toothed structure ensures a tight fit between the screw 603 and the fixing groove 604, preventing slippage. The compression spring 707 causes the drive plate 703 to extend into the slot 204, and the two pressure plates 704 extend into the drive groove 706, causing the toothed plate 701 to retract and allowing the fixing seat 501 to move smoothly. When the latch 205 is rotated to lock, the pin abuts against the drive plate 703, causing the drive plate 703 to move the drive groove 706 symmetrically. The toothed plate 701 abuts against the rack 702, thus limiting the fixed seat 501 and ensuring its stable installation. The buffer spring 705 allows the pressure plate 704 to slide within the toothed plate 701. After the toothed plate 701 and rack 702 are firmly in contact, the pressure plate 704 can continue to slide, allowing the drive plate 703 to slide into place. This facilitates the engagement and locking of the pin and latch 205, and ensures smooth drive control of the drive plate 703.
