Description

Technical Field

[0001] This utility model relates to the field of electric vehicle door lock technology, and more specifically to a reliable electric vehicle door lock. Background Technology

[0002] Currently, with the continuous improvement of people's living standards, automobiles have become deeply integrated into daily life as a core means of transportation. Consumers have significantly increased their demands for vehicle performance, requiring higher standards in terms of cost, safety, and operability beyond basic transportation needs. The reliability of door locks and the real-time nature of unlocking are the biggest challenges faced by technicians.

[0003] However, the aforementioned existing technologies still have some drawbacks. Common car door locks use a latch and a stop block to fix the latch. Impact stress is concentrated on the stop block, and the mechanical structure is susceptible to external impact, which can lead to accidental opening. Especially in extreme temperature or vibration environments, the strength of the stop block decreases, and the door lock is prone to malfunctions, which seriously affects vehicle safety. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a reliable electric vehicle door lock.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a housing, a latch, a stop block, and a matching actuating device for the stop block. The stop block has a first slot and a second slot. The latch has a corresponding first protrusion and a second protrusion, which cooperate to restrict the movement of the latch. A third protrusion extends outward from the second protrusion. The housing is movably connected to a long strip of baffle that adapts to the movement path of the latch and can swing within the housing. The stop block is near the third protrusion to restrict the movement of the latch. The long strip of baffle is near the stop block. The side of the stop block facing the long strip of baffle has a protrusion A with a bevel. The bevel and the contact surface of the long strip of baffle form a sliding guide fit. The latch, the stop block, and the long strip of baffle are all provided with torsion springs for resetting.

[0006] The present invention is further configured such that: the third protrusion is provided with a collision pad, the outer diameter contour of the collision pad protrudes beyond the third protrusion, and the collision pad is rotatable.

[0007] The present invention is further configured such that: the elongated baffle is provided with a baffle plate, and the baffle plate is close to the collision pad block.

[0008] The present invention is further configured such that: the actuating device includes a motor, the motor is connected to a gear A via a worm gear mechanism, the gear A meshes with a gear B, the lower surface of the gear B is provided with a driving protrusion, and the driving protrusion is linked to the stop block.

[0009] The present invention is further configured such that: a pressure sensor is provided inside the housing, and the pressure sensor is close to and in contact with the stop block.

[0010] In summary, this utility model has the following beneficial effects: the long strip baffle, when the utility model is closed, forms a cooperation with the third protrusion, which has a good locking effect on the lock tongue, reduces the stress concentration of the lock tongue when it is impacted, and increases its service life; by setting the second protrusion, when the first protrusion fails, the second protrusion will cooperate with the first slot to prevent the door from opening accidentally when impacted, thus protecting passenger safety.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] This embodiment discloses a reliable electric vehicle door lock, such as Figures 1 to 5As shown, the device includes a housing, a latch 1, a stop block 2, and a matching actuating device for the stop block 2. The stop block 2 is provided with a first slot 21 and a second slot 22. The latch 1 is provided with a first protrusion 11 and a second protrusion 12. The two work together to restrict the movement of the latch (1). When the device is in the open state, the second protrusion 12 works with the second slot 22, so that the latch 1 is close to the opening of the housing. The latch 1 can be well pushed into the locked state by the latch. When the device is in the closed state, the first protrusion 11 works with the first slot 21, so that the first slot 21 can well restrict the movement of the first protrusion 11, so that the latch 1 obtains a good locked state. When the first protrusion 11 is released and the latch 1 rotates and slides out, the second protrusion 12 works with the first slot 21, so that the latch is difficult to slide out, thus protecting the door from being opened. The second protrusion 12 extends outward to form a third protrusion 13. The housing is movably connected to a long strip baffle 3 that is adapted to the movement path of the latch 1 and can swing within the housing. The block 2 is close to the third protrusion 13 to restrict the movement of the latch 1. The long strip baffle 3 is close to the block 2. The block 2 has a protrusion A23 with a bevel on the side facing the long strip baffle 3. The bevel and the contact surface of the long strip baffle 3 form a sliding guide fit. The long strip baffle 3 swings open as the block 2 opens, improving the ease of opening this utility model. The latch 1, the block 2, and the long strip baffle 3 are all provided with torsion springs 4 for resetting.

[0019] Furthermore, the third protrusion 13 is provided with a collision pad 131. The outer diameter of the collision pad 131 protrudes beyond the third protrusion 13. The collision pad 131 can absorb the impact generated when the third protrusion 13 collides with the stop block 2 during movement, thereby reducing the impact force directly received by the third protrusion 13. The collision pad 131 is rotatable, and the rotation can convert sliding friction into rolling friction, making the movement of the locking tongue 1 smoother.

[0020] Further improvements include a stop plate 24 on the elongated baffle 3, which is positioned close to the collision pad 131. The stop plate 24 moves along with the movement of the stop block 2, and its movement trajectory intersects with that of the collision pad 131. This allows the stop plate 24 to contact the collision pad 131 when the latch 1 rotates to close. The collision pad 131 absorbs impacts and reduces the impact on the third protrusion 13 when it enters the locking position. When the latch 1 fails to engage with the stop block 2 and the latch 1 rotates unexpectedly, the stop plate 24 can hold the collision pad 131 in place, preventing the latch 1 from rotating further. Even when the latch 1 fails to engage with the stop block 2, this invention maintains the locked state.

[0021] In a further improvement, the actuating device includes a motor 5, which is connected to a gear A6 via a worm gear mechanism. Gear A6 meshes with gear B7, and a driving protrusion 71 is provided on the lower surface of gear B7. The driving protrusion 71 is linked to the stop block 2. The driving protrusion 71 rotates under the drive of the motor 5 and pushes the stop block 2, making the opening of this utility model simple and convenient; only the motor 5 needs to be started.

[0022] To further improve the design, a pressure sensor 8 is installed inside the housing, which is close to and in contact with the stop block 2. When the stop block 2 is closed, it contacts and presses the pressure sensor 8, and the degree of pressure increases as the stop block 2 is closed. The pressure sensor 8 can detect the closed state of the stop block 2, thereby monitoring the locking state of this invention during use.

[0023] Working principle of this utility model

[0024] When this utility model is in use, when the latch enters the utility model, it will push the latch 1 to rotate. The rotating latch 1 will contact and push the first protrusion 11. At the same time, the collision pad 131 will contact and push the stop plate 24, causing the stop block 2 to rotate and open under force. When the stop block 2 moves, the setting of the protrusion A23 will push the long strip stop 3 to open, so that the latch can enter smoothly. The long strip stop 3 and the stop block 2 will be reset under the action of the torsion spring 4. The third protrusion 13 will cooperate with the reset long strip stop 3. The first protrusion 11 will cooperate with the reset first slot 21. The latch 1 will obtain a good locking state, and the latch will be locked.

[0025] During unlocking, the motor 5 drives the gear A6, which in turn drives the gear B7. The drive protrusion 71 on the gear B7 will open the stop block 2 under the rotation of the gear B7, thereby disengaging the first protrusion 11 from the first slot 21. Furthermore, the elongated baffle 3 will be lifted by the action of the protrusion A23, thereby disengaging the elongated baffle 3 from the third protrusion 13. The locking of the latch 1 will be engaged, and under the action of the torsion spring 4, the latch will be pushed out in reverse.

[0026] When the latch is subjected to a large impact, causing the first protrusion 11 to deform, and the engagement between the first protrusion 11 and the first slot 21 and the engagement between the third protrusion 13 and the elongated baffle 3 both fail, the first protrusion 11 will dislodge from the first slot 21, the second protrusion 12 will engage with the first slot 21, and the baffle plate 24 will hinder the movement of the collision pad 131, so that the latch remains within the present invention, thus protecting safety.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
