Description

Technical Field

[0001] This utility model relates to the field of vehicle door lock technology, and in particular to an electrically operated side door lock. Background Technology

[0002] In the field of automotive door locks, the existing transmission structures are mostly manual mechanical, mainly consisting of lever or cable transmission and auxiliary transmission. Although this type of transmission mechanism can function in some mechanical manual unlocking models, it suffers from a low level of intelligence. Manual operation is not only labor-intensive, but also extremely inconvenient in some special scenarios, such as when hands are inconvenient or when interior space is limited. At the same time, manual mechanical structures are prone to wear and loosening after long-term use, leading to a decrease in the reliability of the door lock and affecting the vehicle's safety and ease of use.

[0003] Therefore, it is necessary to provide an electrically operated side door lock to solve the above-mentioned technical problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] First Embodiment

[0025] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an electrically operated side door lock provided by this utility model; Figure 2 for Figure 1The diagram shows the internal structure.

[0026] Figure 3 for Figure 2 The diagram shows another structural view. An electrically operated side door lock includes: a mounting housing 7;

[0027] Motor 1 is disposed on the inner side of the mounting housing 7. A worm gear 2 is fixedly installed at the output end of the motor 1. A worm wheel 3 is meshed at the top of the worm gear 2. A transmission plate 4 is disposed on the outer side of the worm wheel 3. An outer opening plate 5 and an opening arm 6 are connected to the back of the transmission plate 4.

[0028] The mounting housing 7 has an outer shell 8 on its front side.

[0029] The outer casing 8 is respectively disposed on the outer side of the motor 1, the worm gear 2, the worm wheel 3, the transmission plate 4, the outer opening plate 5, and the opening arm 6.

[0030] The original single-motor drive structure is replaced with a dual-motor drive. One motor controls the lock body's locking and unlocking, while the other controls the electric outward opening. The electric outward opening structure can also coexist with the manual opening structure. When the door lock performs an unlocking action, motor 1 drives worm gear 2 to drive worm wheel 3. Worm wheel 3 drives transmission plate 4 through a cam mechanism. Transmission plate 4 is linked to outward opening plate 5, which in turn pushes opening arm 6 to perform an unlocking action. The transmission structure is relatively simple, more reliable, and the product performance is superior.

[0031] The working principle of the electrically operated side door lock provided by this utility model is as follows:

[0032] When the door lock performs the unlocking action, motor 1 starts after receiving the unlocking signal. The unlocking signal can come from the control button inside the vehicle, such as a button specifically designed to control the opening of the door located near the driver's or passenger's seat. When the driver or passenger presses the button, the signal is transmitted to motor 1 through the vehicle's electrical system. Alternatively, it can come from a smart device, such as a mobile app connected to the vehicle. The user can issue an unlocking command on their mobile phone, and the signal is transmitted to the vehicle via Bluetooth or the network, and then to motor 1.

[0033] The output end of motor 1 drives worm 2 to rotate. Since worm 2 and worm wheel 3 mesh with each other, the rotation of worm 2 drives worm wheel 3 to rotate. During the rotation of worm wheel 3, the cam mechanism on its outer side will move according to a specific curve profile. This movement mode can convert the circular motion of worm wheel 3 into the linear motion or oscillation of transmission plate 4. When transmission plate 4 moves, it will link with the outer opening plate 5 connected to it. The outer opening plate 5 will then push the opening arm 6. The opening arm 6 will then act on the relevant locking components of the door lock to realize the unlocking action, thereby completing the opening of the car door.

[0034] Compared with related technologies, the electric opening side door lock provided by this utility model has the following beneficial effects:

[0035] The electric opening function is realized through the transmission of motor 1, which greatly improves the convenience of door lock use. Users do not need to operate manually and can easily open the door through the control button or smart device in the vehicle. This increases the intelligence of the transmission structure and can be matched with the artificial intelligence of the whole vehicle.

[0036] The motor 1 drives the worm gear 2 to drive the worm wheel 3. The worm wheel 3 drives the transmission plate 4 through the cam mechanism, which in turn links the outer opening plate 5 and the opening arm 6 to perform the unlocking action. The simple structure reduces the number of parts, lowers the probability of failure, and improves the transmission efficiency, making the door lock respond faster and more reliable.

[0037] Second Embodiment

[0038] Please refer to the following: Figure 4 and Figure 5 Based on the electrically operated side door lock provided in the first embodiment of this application, the second embodiment of this application proposes another electrically operated side door lock. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0039] Specifically, the difference in the second embodiment of this application regarding an electrically operated side door lock is that, in an electrically operated side door lock, a plurality of snap-fit ​​frames 10 are fixedly installed on the side of the housing 8, and a plurality of snap-fit ​​strips 9 are fixedly installed on the side of the mounting housing 7.

[0040] Multiple snap-fit ​​strips 9 are snapped onto the inner sides of multiple snap-fit ​​frames 10.

[0041] The housing 8 has a plurality of mounting screws 11 inside.

[0042] One end of each of the mounting screws 11 is threaded into the interior of the front side of the mounting housing 7.

[0043] The working principle of the electrically operated side door lock provided by this utility model is as follows:

[0044] When using the device, if it is necessary to disassemble the mounting shell 7 and the outer shell 8 to maintain the internal components, the user should first use a suitable tool (such as a screwdriver) to turn the mounting screw 11 so that one end of the mounting screw 11 comes out from the internal thread on the front of the mounting shell 7. During the turning process, care should be taken to control the force to avoid stripping the screw or damaging the threaded hole of the mounting shell 7 due to excessive force. Then, remove the mounting screw 11 from the inside of the outer shell 8 to complete the screw removal step.

[0045] The user then presses down on multiple locking strips 9. Due to the elasticity of the locking strips 9, they deform elastically during the pressing process, causing them to move out from the inner side of the locking frame 10. During the operation, it is important to ensure that each locking strip 9 is completely detached from the locking frame 10 to avoid affecting subsequent disassembly. The user can then separate the mounting housing 7 from the outer housing 8, facilitating the inspection, repair, or replacement of internal components such as the motor 1, worm gear 2, and worm wheel 3.

[0046] Compared with related technologies, the electric opening side door lock provided by this utility model has the following beneficial effects:

[0047] The locking strip 9, locking frame 10, and mounting screw 11 work together to allow the locking strip 9 to move out from the inner side of the locking frame 10 and the mounting screw 11 to be threaded out from the inner side of the mounting shell 7 during use. This allows the mounting shell 7 and the outer shell 8 to be disassembled, making it convenient for users to maintain the components located on the inner side of the mounting shell 7 and the outer shell 8.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
