[0002] A car door locking device is used to lock the door to the vehicle body and can be unlocked and locked electrically or manually. The locking device may include a door lock actuator, a pull wire, a lock cylinder located inside the door, and a latch located on the vehicle body. The door lock actuator operates the lock cylinder by pulling the pull wire, establishing or disengaging the connection with the latch, thus achieving the locking and unlocking operations. In other types of locking devices, such as electric soft-close doors, the specific structure of the lock cylinder and latch can be adapted and adjusted according to the principle of electromagnetic attraction.
[0003] Typically, door lock actuators are directly or indirectly connected to the lower part of the inner door panel. During the opening and closing of the door lock, noise is often generated, which will be transmitted into the vehicle through the inner door panel, causing noise interference. On the other hand, since the door lock actuator is located in the lower part of the door, it is at higher risk of water ingress. Summary of the Invention

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0027] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0028] This application is described below with reference to the accompanying drawings and specific embodiments:
[0029] The door locking system installed inside a car door typically includes a door lock actuator to drive the door lock cylinder, which works in conjunction with the latch on the vehicle body to lock and unlock the door. However, the door lock actuator is usually installed in the lower part of the inner door panel, which can easily transmit the noise generated during operation into the vehicle through the inner door panel, causing noise interference; and it also poses a higher risk of water ingress.
[0030] Therefore, embodiments of this application provide a car door and a car, which aim to reduce the operating noise of the lock actuator transmitted from the door to the car door to a certain extent through structural and layout design, thereby improving the impact of noise interference.
[0031] Figure 1 A cross-sectional view of a car door in an embodiment of this application is shown; Figure 2 It shows Figure 1A sectional view of the door lock actuator of a car door in its installation state; Figure 3 It shows Figure 1 A schematic diagram showing the arrangement of door lock actuators in a car door; Figure 4 It shows Figure 1 A schematic diagram showing the arrangement of the door lock actuator and lock cylinder in a car door; Figure 5 It shows Figure 4 A schematic diagram showing the arrangement of door lock actuators on a car door.
[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the car door may include a door body 1 and a door lock actuator 2, the door lock actuator 2 being disposed inside the door body 1; generally, the door body 1 is also provided with a lock head 5, the lock head 5 being connected to the door lock actuator 2 to operate under the drive of the door lock actuator 2, cooperating with a latch or other structure disposed on the car body to lock the door body 1 to the car body, or to unlock it from the car body.
[0033] The door body 1 includes an outer door panel 11, an inner door panel 12, and a window glass 13. The outer door panel 11 and the inner door panel 13 are connected to form the main structure of the door body 1. The door body 1 has a cavity to accommodate various functional mechanisms such as the window glass 13 and the door lock actuator 2. The window glass 13 is movably embedded in the door body 1 and can be specifically positioned between the outer door panel 11 and the inner door panel 12.
[0034] The door lock actuator 2 can be located between the outer door panel 11 and the window glass 13, that is, on the side of the window glass 13 facing the outside of the vehicle. During the operation of the door lock actuator 2, the sound generated will be reduced by the window glass, thereby reducing the sound transmitted into the vehicle to a certain extent and improving the noise impact inside the door.
[0035] On the other hand, since the door lock actuator 2 is located between the outer door panel 11 and the window glass 13, the door lock actuator 2 is also located at a relatively high position in the door body 1, such as the upper middle part, so that the door lock actuator 2 is higher than the water line of the car, which reduces the risk of water entering the door lock actuator 2 to a certain extent.
[0036] The vehicle door and vehicle provided in this application embodiment include a door body and a door lock actuator. The door body includes an outer door panel and an inner door panel, and a window glass between them. The door lock actuator is disposed between the outer door panel and the window glass to form a sound barrier using the window glass, thereby reducing the noise intensity transmitted directly into the vehicle by the door lock actuator to a certain extent. On the other hand, by placing the door lock actuator in the area covered by the window glass, so that the door lock actuator is located in the upper part of the door body, the risk of water ingress into the door lock actuator can be reduced to a certain extent.
[0037] In some embodiments, in order to maintain the noise reduction effect of the window glass 13, the distance between the door lock actuator 2 and each edge of the window glass 13 can be controlled to maintain a good noise suppression effect.
[0038] Specifically, the distance from the door lock actuator 2 to each edge of the window glass can be greater than 10mm, thereby forming a sufficient shielding area between the door lock actuator 2 and the interior of the vehicle body to maintain noise reduction performance to a certain extent.
[0039] It is worth noting that the window glass 13 has two extreme positions, namely the window opening extreme position and the window closing extreme position. The positions of the upper and lower edges of the window glass 13 will change depending on the operating conditions. Therefore, the distance from the door lock actuator 2 to the extreme positions of the upper and lower edges of the window glass 13 is greater than 10mm.
[0040] In some embodiments, in order to enhance the installation stability of the door lock actuator 2 at a high position within the door body 1, the vehicle door may further include an actuator mounting plate 3, which may be directly or indirectly connected to the outer door panel 11, and the door lock actuator 2 is mounted on the actuator mounting plate 3.
[0041] Generally, the actuator mounting plate 3 can be connected to the outer door panel 11 by fasteners or directly welded to the outer door panel 11.
[0042] It is worth noting that the actuator mounting plate 3 is connected to the outer door panel 11 and not to the inner door panel 12, thereby avoiding the direct transmission of noise and vibration into the vehicle through the inner door panel 12, thus reducing the amplitude of noise transmission into the vehicle to a certain extent.
[0043] Since the door lock actuator 2 is directly or indirectly connected to the outer door panel 11, the distance that the vibration of the door lock actuator 2 is transmitted to the inner door panel 12 is much greater than the vibration transmission path length directly connected to the inner door panel 12. This results in vibration attenuation to a certain extent, thereby reducing noise intensity.
[0044] In some embodiments, in order to suppress the resonance noise transmitted between the outer door panel 11 and the door lock actuator 2, the actuator mounting plate 3 can be connected to two different structures on the outer door panel 11, so as to utilize the difference in vibration frequency between the different carriers to offset the vibration effect to a certain extent.
[0045] Generally, the outer door panel 11 is usually provided with an outer panel reinforcing plate 14 and a crash beam 15, and the actuator mounting plate 3 can be connected to the outer panel reinforcing plate 14 and the crash beam 15 respectively.
[0046] It is worth noting that the outer panel reinforcing plate 14 and the anti-collision beam 15 are high-strength structures inside the door body 1. Installing the actuator mounting plate 3 on the outer panel reinforcing plate 14 and the anti-collision beam 15 can improve the installation stability of the door lock actuator 2 to a certain extent.
[0047] In some embodiments, in order to limit the transmission of operating noise from the door lock actuator 2 to the outside, an attractive material can be provided around the door lock actuator 2 to absorb noise to a certain extent, thereby reducing the noise entering the vehicle.
[0048] In some embodiments, the door lock actuator 2 can be disposed between the outer door panel 11 and the outer panel reinforcing plate 2, and sound-absorbing material can be filled between the door lock actuator 2 and the actuator mounting plate 3 to form a sound insulation structure facing the inside of the vehicle. This can stabilize and fix the sound insulation structure and also simplify the size of the sound insulation structure for easier installation.
[0049] In some embodiments, a shock-absorbing material may be filled between the door lock actuator 2 and the actuator mounting plate 3 to directly absorb the vibration of the door lock actuator 2, thereby reducing the vibration transmitted to the door body 1 to a certain extent.
[0050] Figure 6 It shows Figure 1 A schematic diagram showing the arrangement of the door lock actuator and actuator mounting plate of a car door.
[0051] See Figure 6 In some embodiments, the door lock actuator 2 can also be connected to the actuator mounting plate 3 by a shock-absorbing fastener 16 to reduce the vibration energy transmitted from the door lock actuator 2 to the actuator mounting plate 3, thereby reducing noise to a certain extent.
[0052] Generally, the shock-absorbing fastener 16 can be a shock-absorbing bolt.
[0053] In some embodiments, the door lock actuator 2 may be disposed in the upper region of the door body 1, so that the door lock actuator 2 is at a relatively high position, and the door lock actuator 2 is higher than the water line of the vehicle body, thereby reducing the risk of water ingress of the door lock actuator 2.
[0054] See Figure 3 , such as 4, Figure 5 and Figure 6 In some embodiments, the door lock actuator 2 can be connected to the lock head 5 via a cable 4, and one end of the cable 4 connected to the door lock actuator 2 can be lower than the end of the cable 4 connected to the lock head 5, so that the lock head 5 can be pulled downward at a position slightly lower than the lock head 5, thereby maintaining the door lock actuator 2 at a relatively high position to adapt to the position of the vehicle window glass 13.
[0055] Generally, the cable 4 can be configured as an arc shape, and the arc shape can be maintained by the guide fastener 17 to ensure the reliability of unlocking and locking.
[0056] In some embodiments, an automobile is also provided, including an automobile door as described above, the door body being connected to the vehicle body via a hinge, and the vehicle body being provided with a latch that cooperates with the lock head 5.
