Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an electric locking body, a vehicle door, and a vehicle. Background Technology

[0002] With the continuous advancement of vehicle technology, automobiles are becoming increasingly feature-rich. To enhance the overall quality of the vehicle and the user experience, some models are equipped with power-closing doors to achieve automatic door closure. During the closing process, the latch first enters the semi-lock position of the power-closing lock body, forming an initial lock; once the detection element recognizes that the door has reached the semi-lock position, the locking mechanism then begins to move, pushing the latch to the fully locked position to complete the final locking.

[0003] However, since the detection element requires a certain response time, if the door closes too quickly and the latch passes the detection position rapidly, the detection signal may not be able to trigger the locking mechanism in time. At this point, although the door has entered the fully locked area, the locking mechanism has not yet completed locking, causing the door to bounce back, making the locking process less smooth and affecting the user experience. Utility Model Content

[0004] This application provides an electrically operated lock body, a door heat sink, and a vehicle to solve related technical problems.

[0005] The first aspect of this application provides an electrically engaging lock body, comprising: a housing, a locking member, a driving member, and a blocking member; the housing is provided with a locking space, and the locking member is installed in the locking space; the locking space includes a half-locking space, a full-locking space, and a latching hole, the half-locking space connecting the latching hole and the full-locking space; the electrically engaging lock body is provided with a detection element for detecting the latch in the half-locking space; the locking member is provided with a locking portion; the driving member is poweredly connected to the locking member so that the locking portion moves between the half-locking space and the full-locking space; the blocking member is assembled to the housing and is at least partially located between the half-locking space and the full-locking space.

[0006] By placing a blocking element between the half-lock space and the full-lock space, the latch is blocked after entering the half-lock space, preventing it from quickly crossing the half-lock space into the full-lock space. Once blocked, the latch will temporarily remain in the half-lock space, ensuring that the detection element can promptly detect the latch entering the half-lock position and trigger the full-lock action, thus improving the smoothness of the electric locking mechanism.

[0007] Furthermore, the blocking member is movably connected to the housing and its direction of movement intersects the axial direction of the latch inlet hole; the blocking member includes a main body portion located outside the locking space and a blocking portion protruding into the locking space from one side of the main body portion, and the blocking member is movably connected to the housing. The movable connection of the blocking member to the housing allows it to avoid the latch when it enters, so the latch only needs to move along the axial direction of the latch inlet hole, reducing the complexity of the relative movement between the electric locking body and the latch, and further improving the smoothness of the electric locking body's engagement.

[0008] Furthermore, the blocking portion includes a first surface and a second surface, the first surface facing the semi-locking space and the second surface facing the full-locking space, and at least one of the first surface and the second surface is inclined relative to the axial direction of the latch inlet hole. When the latch impacts the first surface or the second surface during the closing process, the inclined arrangement of the first surface or the second surface disperses the impact force, reduces the force applied perpendicularly to the surface of the blocking member, and improves the stability of the electrically engaged lock body.

[0009] Furthermore, the first surface and the second surface extend close to each other from the main body, and an elastic element is provided on the side of the main body opposite to the blocking part. When the latch moves from the semi-locking space to the fully locked space, the blocking element moves under the pressure of the latch to avoid it. Once the latch enters the fully locked space, the blocking element returns to its original position under the elastic force of the elastic element, thus limiting the latch's movement within the fully locked space. Using an elastic element to move the blocking element results in a simple structure and a smooth process, improving the locking smoothness of the electrically operated lock body.

[0010] Furthermore, the angle between the first surface and the axis of the latching hole is greater than the angle between the second surface and the latching hole. Because the angle between the first surface and the axis of the latching hole is larger, the reaction force generated by the first surface along the axis of the latching hole is increased, improving the blocking effect of the blocking element on the latch, reducing the movement speed of the latch within the semi-locked space, ensuring that the detection element can perform timely detection, and further improving the smoothness of the electric locking body. Because the angle between the second surface and the axis of the latching hole is smaller, the reaction force generated by the second surface along the axis of the latching hole is reduced, reducing the force required by the user during the unlocking process and improving the user experience.

[0011] Furthermore, the end of the blocking member away from the latch inlet is rotatably connected to the housing. Because the blocking member is rotatably connected to the housing, during latch insertion, the first surface gradually rotates to be perpendicular to the axis of the latch inlet, further improving the blocking effect, reducing the latch's movement speed, ensuring timely detection by the detection element, and improving the smoothness of the electric latch lock's engagement. During unlocking, as the latch moves outward from the fully locked position, the second surface gradually rotates to be parallel to the axis of the latch inlet, further reducing the force required by the user during unlocking and improving the user experience.

[0012] Furthermore, the blocking part also includes a transition arc surface, which connects the first surface and the second surface. By providing the transition arc surface, hard collisions between the latch and the blocking member are avoided during movement, further improving the smoothness of the electric locking body.

[0013] Furthermore, the blocking element is in the form of a sheet. The sheet-shaped blocking element is easy to manufacture and improves the production efficiency of the electric engagement lock body.

[0014] A second aspect of this application provides a vehicle door, including the aforementioned electrically operated locking body. Because the electrically operated locking body provides superior smoothness of locking, the smoothness of closing the vehicle door of this application is also improved.

[0015] A third aspect of this application provides a vehicle including a latch and the aforementioned door. Due to the smooth closing of the door, the driving experience of the vehicle is improved.

Detailed Implementation

[0020] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0021] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0022] During the process of a car door transitioning from a half-locked to a fully locked position, the detection element requires a certain response time. If the door closes too quickly, the latch will pass the detection position rapidly, and the detection signal may not be able to trigger the locking mechanism in time. At this point, although the door has entered the fully locked area, the locking mechanism has not yet completed locking, causing the door to bounce back, making the locking process less smooth and affecting the user experience.

[0023] like Figures 1 to 3 As shown, the first aspect of this application provides an electrically engaging lock body, including a housing 10, a locking member 20, a driving member 30, and a blocking member 40. The housing 10 is provided with a locking space 100, and the locking member 20 is installed in the locking space 100.

[0024] The locking space 100 includes a semi-locking space 101, a full-locking space 102, and a latching hole 103. The semi-locking space 101 connects the latching hole 103 and the full-locking space 102. The electrically engaged lock body is equipped with a detection element (not shown) for detecting the latch 50 within the semi-locking space 101.

[0025] The locking member 20 is provided with a locking part 21. The locking part 21 is a structure for locking the latch 50. The driving member 30 is poweredly connected to the locking member 20 so that the locking part 21 can move between the half-lock space 101 and the full-lock space 102. The blocking member 40 is assembled to the housing 10 and is at least partially located between the half-lock space 101 and the full-lock space 102.

[0026] By setting a blocking element between the half-lock space 101 and the full-lock space 102, the latch 50 is blocked after entering the half-lock space 101, preventing the latch 50 from quickly crossing the half-lock space 101 into the full-lock space 102. After being blocked, the latch 50 will temporarily remain in the half-lock space 101, ensuring that the detection element can detect the latch entering the half-lock position in a timely manner and trigger the full-lock action, thus improving the smoothness of the electric locking body.

[0027] The sensing element can be a Hall sensor, which detects the rotational position of the locking part 21 to determine whether the latch 50 has entered a semi-locked state. The latch 50 can remain in the semi-locked space 101 for more than 20ms to ensure normal detection by the sensing element.

[0028] The drive unit 30 includes a power unit 31 and a pull rope unit 32. The power unit 31 can be a power element such as a motor, which provides power to the pull rope unit 32. The pull rope unit 32 is connected to the locking part 21. When the detection element detects that the latch 50 has entered the semi-locking space 101, the power unit 31 starts to work and pulls the pull rope unit 32. The pull rope unit 32 pulls the locking part 21 to rotate, thereby causing the latch 50 to enter the fully locked space 102.

[0029] The blocking element 40 is plate-shaped. The plate-shaped blocking element 40 facilitates manufacturing and improves the production efficiency of the electric locking body. The blocking element 40 is movably connected to the housing 10, and its direction of movement intersects the axial direction of the latching hole 103. Please refer to the following: Figure 4 As shown, the blocking member 40 includes a main body 41 located outside the locking space 100 and a blocking part 42 protruding from one side of the main body 41 into the locking space 100. The blocking member 40 is movably connected to the housing 10.

[0030] The blocking member 40 is movably connected to the housing 10, allowing it to avoid the latch 50 when it enters. The latch 50 only needs to move along the axis of the latch inlet hole 103, reducing the complexity of the relative movement between the electric locking body and the latch 50 and further improving the smoothness of the electric locking body's engagement. In other embodiments, the blocking member 40 can remain fixed, and by designing a corresponding movement path, the latch 50 can bypass the blocking member 40 after abutting it and enter the full locking space 102.

[0031] The blocking part 42 includes a first surface 421 and a second surface 422. The first surface 421 faces the semi-locking space 101, and the second surface 422 faces the full-locking space 102. At least one of the first surface 421 and the second surface 422 is inclined relative to the axial direction of the latch inlet hole 103. When the latch 50 impacts the first surface 421 or the second surface 422 during the closing process, the impact force is dispersed due to the inclined arrangement of the first surface 421 or the second surface 422, reducing the force applied perpendicularly to the surface of the blocking member 40 and improving the stability of the electro-engaging lock body.

[0032] The first surface 421 and the second surface 422 extend close to each other from the main body 41, and an elastic member 43 is provided on the side of the main body 41 away from the blocking part 42. When the latch 50 moves from the semi-locking space 101 into the full-locking space 102, the blocking member 40 is pressed by the latch 50 and moves to avoid it. After the latch 50 enters the full-locking space 102, the blocking member 40 is returned to its original position by the elastic force of the elastic member 43, thus limiting the latch 50 within the full-locking space 102. Using the elastic member 43 to move the blocking member 40 results in a simple structure and a smooth process, improving the locking smoothness of the electrically engaged lock body.

[0033] The elastic element 43 can be a spring, which can provide an elastic force of 30N. During the closing process of the electrically engaged lock body, the locking force of the half lock is less than or equal to 75N. That is, along the movement direction of the latch 50, a force of less than or equal to 75N needs to be provided to the latch 50 so that the latch 50 enters the half-lock space 101 and abuts against the blocking element 40. During the electrically engaged process, that is, during the process of the latch 50 moving from the half-lock space 101 to the full-lock space 102, the driving element 30 can generate a force greater than 500N. That is, along the movement direction of the latch 50, the driving force on the latch 50 is greater than 500N to overcome the elastic force of the spring 30N.

[0034] The angle between the first surface 421 and the axis of the latching hole 103 is greater than the angle between the second surface 422 and the latching hole 103. Because the angle between the first surface 421 and the axis of the latching hole 103 is larger, the reaction force generated by the first surface 421 along the axis of the latching hole 103 is increased, improving the blocking effect of the blocking member 40 on the latch 50, reducing the movement speed of the latch 50 within the semi-lock space 101, ensuring that the detection element can perform timely detection, and further improving the smoothness of the electric locking body. Because the angle between the second surface 422 and the axis of the latching hole 103 is smaller, the reaction force generated by the second surface 422 along the axis of the latching hole 103 is reduced, decreasing the force required by the user during the unlocking process and improving the user experience.

[0035] The end of the blocking member 40 away from the latch inlet 103 is rotatably connected to the housing 10. Because the blocking member 40 is rotatably connected to the housing 10, during the insertion of the latch 50, the first surface 421 gradually rotates to be perpendicular to the axis of the latch inlet 103, further improving the blocking effect of the blocking member 40, reducing the moving speed of the latch 50, ensuring timely detection by the detection element, and improving the smoothness of the electric locking mechanism. During unlocking, as the latch 50 moves outward from the full lock space 102, the second surface 422 gradually rotates to be parallel to the axis of the latch inlet 103, further reducing the force required by the user during unlocking and improving the user experience.

[0036] The blocking part 42 also includes a transition arc surface 423, which connects the first surface 421 and the second surface 422. By setting the transition arc surface 423, hard collisions between the latch 50 and the blocking part 40 are avoided during movement, further improving the smoothness of the electric engagement lock body.

[0037] A second aspect of this application provides a vehicle door, including the aforementioned electrically operated locking body. Because the electrically operated locking body provides superior smoothness of locking, the smoothness of closing the vehicle door of this application is also improved.

[0038] A third aspect of this application provides a vehicle including a latch 50 and the aforementioned door. The latch 50 is installed on the B-pillar or C-pillar of the vehicle. Due to the smooth closing of the door, the driving experience of the vehicle is improved. The vehicle can be an electric vehicle, a gasoline-powered vehicle, or a hybrid vehicle, and the specific type is not limited.

[0039] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
