[0002] With the rapid development of vehicle automation and intelligence, more and more models are adopting electric door designs in the rear cabin to enhance the driving and riding experience and make operation more convenient.

[0003] To facilitate entry and exit for rear passengers, rear doors are typically designed with a wide opening. However, with such a wide door opening, rear passengers often need to turn sideways or bend over to reach the power door handle and operate the door, which can lead to a poor passenger experience. Furthermore, the power door switches are usually located on the door panel or pillar trim, adding visual separation and disrupting the overall design aesthetics and visual consistency of the vehicle. Summary of the Invention

[0004] In view of this, this application provides a vehicle door lock system and vehicle to solve the problem that the design of the door handle for opening and closing electric doors in the prior art is inconvenient for rear passengers to close the door and disrupts the overall shape of the vehicle interior.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A door lock system for electric doors, comprising:

[0007] The door drive mechanism is capable of opening and closing the door;

[0008] Carpet-like structure, used to be laid on the floor of the rear seats of a vehicle;

[0013] Above the sensor is the pressure zone of the blanket layer. The substrate layer has a weakened structure, and the deformability of the substrate layer in the pressure zone is greater than that of the substrate layer outside the pressure zone.

[0014] Optionally, the weakening structure is a weakening groove formed by local subtraction on the lower surface of the substrate layer, and the weakening groove is distributed around the edge of the pressing area.

[0015] Optionally, the buffer layer has a mounting slot for accommodating the sensor.

[0016] Optionally, the surface of the carpet structure is provided with a marking for indication, which is positioned directly opposite the sensor.

[0017] Optionally, the identifier includes a silkscreened outline and a silkscreened symbol located at the center of the silkscreened outline.

[0018] Optionally, the sensor is a micro switch or a pressure sensor.

[0019] Optionally, the side of the carpet structure closest to the front seat is designated as the front side, and the sensor is arranged close to the front side of the carpet structure.

[0020] A vehicle includes a door lock system as described above, wherein the vehicle's electronic control unit is communicatively connected to the door drive device and the sensor.

[0021] The door lock system provided in this application is applicable to electric doors. The door lock system includes a door drive unit, a carpet structure, and sensors. The door drive unit is capable of opening and closing the door. The carpet structure is laid and connected to the rear floor of the vehicle. The sensors are installed in the carpet structure and are communicatively connected to the door drive unit. The sensors are capable of sensing the stepping force and being triggered so that the door drive unit can receive signals to open and close the door. With this setup, the sensor acts as a trigger switch for opening and closing the door. Since it is integrated into the carpet structure on the vehicle floor, rear passengers can apply pressure to the sensor by stepping on it. Once triggered, the door drive mechanism can then open or close the door accordingly. This design shortens the operating distance for rear passengers, eliminating the need to bend over, turn to the side, or reach out to open or close the door, making it convenient and easy to operate. Moreover, since the sensor is integrated into the existing carpet structure on the vehicle floor, it also minimizes disruption to the interior design, enhancing the overall quality and technological feel of the vehicle's interior. This solves the problem of existing electric door handle designs that are inconvenient for rear passengers to close the door and disrupt the overall interior design. Attached Figure Description

[0031] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] As shown in Figures 1-3, this application provides a vehicle door lock system suitable for electric doors. The vehicle door lock system includes a door drive device, a carpet structure 1, and a sensor 2. The door drive device is capable of opening and closing the door. The carpet structure 1 is laid on and connected to the rear floor of the vehicle, providing a stepping area. The sensor 2 is disposed in a localized area of ​​the carpet structure 1, and the sensor 2 is communicatively connected to the door drive device via the vehicle's electronic control unit (ECU). The sensor 2 can sense the stepping force and be triggered, so that the door drive device can receive signals to open and close the door. The rear floor of the vehicle is also known in the art as vehicle floor sheet metal.

[0033] With this configuration, sensor 2 acts as a trigger switch for opening and closing the door. Since it is installed on the floor inside the vehicle based on the carpet structure 1, rear passengers can apply pressure to the bottom of the vehicle by stepping on it, thereby applying pressure to sensor 2. After triggering sensor 2, the door drive device can then perform the corresponding opening or closing action. This design shortens the operating distance for rear passengers, eliminating the need to bend over, turn to the side, or reach out to open and close the door, making operation convenient and easy. Moreover, since sensor 2 is integrated into the carpet structure 1 that is already present on the vehicle floor, it also reduces the disruption to the interior design, enhances the overall quality and technological feel of the vehicle's interior, and solves the problem of existing electric door handle designs that are inconvenient for rear passengers to close the door and disrupt the overall interior design.

[0034] It should be noted that the door drive mechanism is a standard feature of electric doors in the prior art. A typical door drive mechanism is designed where the power of a motor is transmitted to a rack and pinion or other transmission mechanism via a gear set. The rack and pinion push the door to slide along a guide rail, thus realizing the opening and closing actions of the door. Simultaneously, a retractable electric limiter is used to limit the opening and closing angle of the door, ensuring safe opening and closing. The door drive mechanism in this application can utilize existing designs and will not be described in detail here.

[0035] Regarding the actual control strategy of the vehicle's electronic control unit (ECU) for the door drive mechanism, after sensor 2 is triggered, it transmits a signal to the ECU. The ECU then calculates the signal and sends an action signal to the door drive mechanism. Specifically, when the ECU detects that the door is open and sensor 2 is triggered, the ECU controls the door drive mechanism to close the door. When the ECU detects that the door is closed and sensor 2 is triggered, the ECU controls the door drive mechanism to open the door. In addition, when the ECU detects that the vehicle is in motion or the door lock is locked, the door drive mechanism will not move even if sensor 2 is subjected to a pedal force.

[0036] In some specific embodiments, the carpet structure 1 includes a carpet surface layer 11 and a cushioning layer 12 arranged in layers, with the cushioning layer 12 connected to the lower surface of the carpet surface layer 11; the sensor 2 is disposed between the carpet surface layer 11 and the cushioning layer 12. That is, the surface layer 11 is the outermost layer of the carpet structure 1, which is the layer visible to the occupants, while the cushioning layer 12 is in direct contact with and connected to the rear floor. The cushioning layer 12 has sound absorption and shock absorption functions, while also providing the carpet structure 1 with softness and elasticity, offering a comfortable feel underfoot for the occupants.

[0037] Further, in some preferred embodiments, the carpet layer 11 includes a base layer 112 and a pile surface layer 111 connected to the upper surface of the base layer 112, and the buffer layer 12 is connected to the lower surface of the base layer 112; above the sensor 2 is the pressure zone 1101 of the carpet layer 11, and the base layer 112 has a weakening structure, making the deformability of the base layer 112 in the pressure zone 1101 greater than the deformability of the base layer 112 outside the pressure zone 1101. That is, when subjected to the same stepping force, the pressure zone 1101 is more likely to collapse downward than the surrounding area outside the pressure zone 1101, thereby triggering the sensor 2. The weakening structure can be located in the pressure zone 1101 or at the edge of the pressure zone 1101. Preferably, the base layer 112 and the pile surface layer 111 are a composite structure.

[0038] This design, by creating a weakened structure in a localized area of ​​the base layer 112 and constructing a weak area in a localized area of ​​the carpet layer 11 that is prone to collapse and close to the sensor 2, makes it easier for rear passengers to step on the carpet.

[0039] In some preferred embodiments, the weakening structure is a weakening groove 1102 formed by partial subtraction of the lower surface of the substrate layer 112, and the weakening groove 1102 is distributed around the edge of the pressing area 1101. The lower surface of the substrate layer 112 can be weakened by laser engraving to form the weakening groove 1102, which facilitates the application of force and operation by the occupants, ensuring the integrity of the carpet structure 1 surface layer without affecting its functionality.

[0040] Of course, in addition to the above methods, it is also feasible to reduce the thickness of the substrate layer 112 in the pressure zone 1101.

[0041] It should be noted that the base layer 112 can be made of materials such as PET or EVA, the velvet surface layer 111 can be made of flocking, etc., and the cushioning layer 12 can be made of foam material or cotton pad, etc.

[0042] In some other preferred embodiments, the buffer layer 12 has a mounting groove 1201 for accommodating the sensor 2. The shape of the mounting groove 1201 is adapted to the shape of the sensor 2. In this way, the mounting groove 1201 provides a mounting position and also helps to stabilize the position of the sensor 2.

[0043] In some other preferred embodiments, the surface of the carpet structure 1 is provided with a marking for indication, which is positioned directly opposite the sensor 2, or in other words, the marking is located in the pressure area 1101. This arrangement provides occupants with clear indication of the stepping position, a user-friendly design.

[0044] Furthermore, in some specific embodiments, the identifier includes a silkscreened outline 3 and a silkscreened symbol 4 located at the center of the silkscreened outline 3. Exemplarily, the silkscreened outline 3 and the silkscreened symbol 4 can be set on the velvet surface layer 111 by screen printing, and the silkscreened symbol 4 can be lock-shaped; the range of the silkscreened outline 3 is substantially consistent with the range of the pressing area 1101; the silkscreened outline 3 can be set in a single loop or multiple loops.

[0045] In some optional embodiments, sensor 2 is a microswitch or a pressure sensor. Exemplarily, it is preferably set as a microswitch, which has the advantages of small size and high sensitivity, thus facilitating a rapid response from the vehicle door lock system. When set as a pressure sensor, a preset trigger pressure threshold can be used.

[0046] For ease of description, the side of the carpet structure 1 closest to the front seat is defined as the front side. In some other preferred embodiments, the sensor 2 is arranged close to the front side of the carpet structure 1. In this way, the pressure area 1101 is located in the area where the occupant's toes are located, which is easily visible to the occupant from a visual perspective and is more conspicuous; moreover, operating with the toes is more in line with human movement habits and conforms to ergonomic design.

[0047] Based on the aforementioned door lock system, this application also provides a vehicle that includes the aforementioned door lock system, wherein the vehicle's electronic control unit is communicatively connected to the door drive device and sensor 2. Since the vehicle has the aforementioned door lock system, the beneficial effects brought by the vehicle through the door lock system are described above and will not be repeated here.
