Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and in particular to a side sliding door mechanism and an automobile. Background Art

[0002] A door frame is a frame on a vehicle with an entrance and exit, which is the necessary path for passengers to enter and exit the vehicle cabin and retrieve and place items. Common door types used to cover the entrance and exit in vans are side sliding doors. Prior to this application, side sliding doors were opened and closed by translation. A four-bar sliding door linkage connecting the side sliding door and the door frame allowed the door to slide parallel to the door frame to open.

[0003] Due to process limitations, it is impossible to completely eliminate the gaps between components during processing and assembly. The gaps between components will cause the side sliding door to shake during the opening and closing process, and it will not be able to move completely along the designed trajectory, resulting in an unstable opening and closing process of the side sliding door. When closing the door, it may hit the side panel metal on the front side of the door frame, and may even be unable to return to its original position. Summary of the Invention

[0056] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0057] It should be understood that, in the description of this application, the terms "upper," "lower," "front," "rear," "bottom," "inner," and "outer" and the like indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. The inner side of the side sliding door 2 referred to in this application is the direction in which the side sliding door 2 approaches the vehicle door frame 1, and the outer side of the side sliding door 2 is the direction in which the side sliding door 2 moves away from the vehicle door frame 1.

[0058] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. That is, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0059] It should be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0060] like Figure 1-13 As shown, an embodiment of the present invention provides a side sliding door mechanism 100, which includes a door frame 1 having an entrance and exit, and a side sliding door 2 for covering the entrance and exit. The side sliding door 2 moves relative to the entrance and exit via a connecting unit 3, thereby closing or opening the entrance and exit. The door frame 1 is a part of the vehicle frame specifically used to mount the door, and the entrance and exit on the door frame 1 is used by users to enter and exit the vehicle.

[0061] It should be noted that due to process limitations, the gaps between components cannot be completely eliminated during processing and assembly. The gaps between components will cause the side sliding door 2 to shake during the opening and closing process, and it will not be able to move completely along the designed trajectory, resulting in an unstable opening and closing process of the side sliding door 2, and the side sliding door 2 will collide with the door frame 1.

[0062] Based on the above problems, the side sliding door mechanism 100 provided in this embodiment further includes a locking unit 4, such as Figure 6-13As shown, the locking unit 4 includes a first locking member 41 and a second locking member 42. The first locking member 41 is installed on the vehicle door frame 1, and the second locking member 42 is installed on the side sliding door 2. When the side sliding door 2 closes the entrance and exit, the first locking member 41 and the second locking member 42 are locked together. Specifically, the first locking member 41 is fixedly installed on the front side of the vehicle door frame 1, and the second locking member 42 is installed on the front side of the side sliding door 2. The positions of the first locking member 41 and the second locking member 42 are relative. When the side sliding door 2 is in a closed state, the first locking member 41 and the second locking member 42 are locked together to achieve locking of the side sliding door 2 and the vehicle door frame 1.

[0063] The first locking member 41 is provided with a guide portion 43 and a locking portion 44, sequentially extending from the second locking member 42 toward the second locking member 42. As the side sliding door 2 closes the entrance or exit, the front end of the side sliding door 2 gradually approaches the front end of the vehicle door frame 1. After the second locking member 42 contacts the first locking member 41, it moves along the guide portion 43, placing the side sliding door 2 and the vehicle door frame 1 in a semi-locked state. Under the action of the guide portion 43, the second locking member 42 drives the side sliding door 2 along the guide portion 43 until the second locking member 42 reaches the locking portion 44, achieving a locked engagement between the first locking member 41 and the second locking member 42, thereby locking the side sliding door 2 and the vehicle door frame 1. This completes the door closing action, ensuring smooth closing of the side sliding door 2 and preventing collision between the side sliding door 2 and the vehicle door frame 1. This resolves the issue of gaps between components preventing the side sliding door 2 from fully following its designed trajectory.

[0064] Taking into account the actual situation, the door may fall or twist due to factors such as its own weight and assembly errors. When closing the door, it may hit the side panel metal on the front side of the door frame 1, and may even be unable to return to its original position. To address this problem, this embodiment provides a locking unit 4 on the front side of the side sliding door mechanism 100, and provides a guide portion 43 on the first locking member 41, so that the side sliding door 2 moves along the trajectory defined by the guide portion 43, assisting the side sliding door 2 to close the door according to the theoretically designed door trajectory, thereby eliminating the gap between components that causes the side sliding door 2 to shake or move in a deviation.

[0065] Preferably, the locking portion 44 has a hook groove opening toward the door frame 1. The second locking member 42 moves along the guide portion 43 into the hook groove, thereby achieving hooked locking between the first locking member 41 and the second locking member 42. Further preferably, the second locking member 42 includes a first plate 45, a second plate 46, and a column 47. The first plate 45 and the second plate 46 are spaced vertically apart and are respectively fixedly connected to the front side of the sliding door 2. The column 47 is fixedly connected between the first plate 45 and the second plate 46. The first plate 45, the column 47, the second plate 46 and the side sliding door 2 are enclosed into a hook; the side sliding door 2 and the door frame 1 are locked by hooking and locking the hook with the hook groove, which acts as a door lock; specifically, under the action of the locking unit 4 and the door frame 1, the displacement of the side sliding door 2 relative to the door frame 1 in the inward and outward directions is restricted; the first locking member 41 restricts the side sliding door 2 from moving toward the outside of the door frame 1, and the door frame 1 restricts the side sliding door 2 from moving toward the inside of the door frame 1, thereby ensuring the stability of the side sliding door 2 in the closed state.

[0066] Preferably, Figure 1-5 As shown, the connecting unit 3 includes a first link 34, a second link 35, a second hinge 32, and a third hinge 33. The first link 34 and the second link 35 are spaced apart and arranged in parallel in the up and down directions. One end of the second hinge 32 is fixedly connected to the door frame 1, and the other end of the second hinge 32 is rotatably connected to the first end of the first link 34. One end of the third hinge 33 is fixedly connected to the side sliding door 2, and the other end of the third hinge 33 is rotatably connected to the second end of the first link 34.

[0067] Further preferably, the side sliding door mechanism 100 provided in this embodiment also includes a first driving mechanism 5 and a first hinge 31, the first hinge 31 includes a sliding groove seat 311 with a first sliding groove 312 and a first rotating shaft 313 slidable in the first sliding groove 312, and the first sliding groove 312 extends along the inward and outward directions of the side sliding door 2; the sliding groove seat 311 and the first driving mechanism 5 are both fixedly connected to the vehicle door frame 1, one end of the second connecting rod 35 is rotatably connected to the first rotating shaft 313, and the other end of the second connecting rod 35 is rotatably connected to the side sliding door 2 through the second rotating shaft.

[0068] The connection line between the first rotating shaft 313 and the door frame 1 is at a preset distance, and the first driving mechanism 5 is used to drive the first rotating shaft 313 to slide in the first sliding groove 312 so that the length of the preset distance changes.

[0069] The side sliding door 2 can move relative to the entrance and exit so that the side sliding door 2 has a closed state and an open state. The side sliding door 2 before this application is opened and closed by a translational movement, and the side sliding door 2 is always parallel to the door frame 1.

[0070] The present invention, by varying the aforementioned preset distances, forms different four-bar linkages between the first rotating shaft 313, the second hinge 32, the third hinge 33, and the second rotating shaft. Varying the preset distances causes the length of the virtual link between the first rotating shaft 313 and the first hinge 31 to change, thereby enabling the side sliding door 2 to have different motion trajectories than before. These different motion trajectories can be achieved by allowing the side sliding door 2 to be parallel to or tilted relative to the vehicle door frame 1, thereby providing a wider range of motion options for the side sliding door 2 when opening and closing.

[0071] The first drive mechanism 5 is configured to drive the first rotating shaft 313 to slide within the first sliding groove 312, thereby moving the first rotating shaft 313 toward or away from the door frame 1. The side sliding door 2 is parallel to the door frame 1, allowing the side sliding door 2 to precisely cover the entrance. The side sliding door 2 is tilted relative to the door frame 1, allowing the rear edge of the side sliding door 2 to separate from the rear edge of the door frame 1 first during the door opening process.

[0072] Preferably, the first drive mechanism 5 includes a first motor 51 and a transmission member 52. The first motor 51 is fixedly connected to the door frame 1. The first end of the transmission member 52 is fixedly connected to the output shaft of the first motor 51. The second end of the transmission member 52 defines a second slide groove 53. Opposite ends of the first rotating shaft 313 are slidably disposed in the first slide groove 312 and the second slide groove 53, respectively. The transmission member 52 rotates around the output shaft of the first motor 51 to drive the first rotating shaft 313 to slide in the first slide groove 312. The intersection of the first slide groove 312 and the second slide groove 53 in the vertical direction is the location of the first rotating shaft 313.

[0073] Furthermore, the embodiment of the present invention further includes: a second drive mechanism 6; the second drive mechanism 6 is used to drive the first hinge 31 to rotate. Specifically, the second drive mechanism 6 can be a second motor, which is disposed on the door frame 1. The output shaft of the second motor is coaxially connected to the rotation axis of the second hinge 32. By driving the second hinge 32 to rotate, the first connecting rod 34 is driven to rotate, thereby driving the second connecting rod 35 to follow.

[0074] In this embodiment, the end of the first slide 312 away from the door frame 1 is defined as the first position, and the end of the first slide 312 closer to the door frame 1 is defined as the second position. When the first rotating shaft 313 is in the first position, the distance between the first rotating shaft 313 and the second hinge 32 is a first preset distance. When the first rotating shaft 313 is in the second position, the distance between the first rotating shaft 313 and the second hinge 32 is a second preset distance. The first preset distance is greater than the second preset distance. By varying the preset distances, different four-bar linkage structures are formed between the first rotating shaft 313, the second hinge 32, the third hinge 33, and the second rotating shaft. Varying the preset distances creates a virtual link between the first rotating shaft 313 and the second hinge 32, allowing the side sliding door 2 to have a different motion trajectory than before. The motion trajectory of the side sliding door 2 will be explained below. The side sliding door 2 is parallel to the door frame 1 in both the closed and open states.

[0075] When the sliding door 2 switches from the closed state to the open state:

[0076] When the side sliding door 2 is in the closed state and the first rotating shaft 313 is in the first position, the first motor drives the first rotating shaft 313 to switch from the first position to the second position, and the second driving mechanism 6 drives the second hinge 32 to rotate, so as to drive the side sliding door 2 from the closed state (such as Figure 2 ) switches to the first state (as shown) Figure 3 as shown); Figure 1-3 As shown, during the switching process, the first motor 51 drives the first rotating shaft 313 to switch from the first position to the second position, and the rear edge of the side sliding door 2 first rotates around the front edge of the side sliding door 2 to tilt the side sliding door 2 and the door frame 1; in the first state, the front edge of the side sliding door 2 is in contact with the front edge of the door frame 1, and the rear edge of the side sliding door 2 is separated from the rear edge of the door frame 1; in the process of switching the side sliding door 2 from the closed state to the first state, the rear edge of the side sliding door 2 is first separated from the rear edge of the door frame 1, which can solve the problem that due to errors in the production process of the side sliding door 2 and the door frame 1, the rear edge of the side sliding door 2 will collide with the rear edge of the entrance and exit during the opening process of the side sliding door 2.

[0077] At the same time, it should be noted that when the side sliding door 2 switches from the closed state to the first state, the rear edge of the side sliding door 2 first rotates around the front edge of the side sliding door 2, and the side sliding door 2 and the door frame 1 are tilted; thereby, the second locking member 42 can slide out of the hook groove, thereby unlocking the side sliding door 2 and the door frame 1.

[0078] See also Figure 4 and Figure 5, the first motor 51 drives the first rotating shaft 313 to continue to move in the second direction, and the inclination angle between the side sliding door 2 and the door frame 1 gradually increases; however, in order to avoid the side sliding door 2 and the door frame 1 being tilted, resulting in a large space occupied by the side sliding door 2 after opening, the first rotating shaft 313 is in the second position at this time, and the first motor 51 drives the first rotating shaft 313 to move from the second position to the first position, that is, to switch from the state where the sliding door and the door frame 1 are tilted to the state where the sliding door and the door frame 1 are parallel.

[0079] When the sliding door 2 switches from the open state to the closed state:

[0080] When the side sliding door 2 is in the open state and the first rotating shaft 313 is in the first position, the second driving mechanism 6 drives the first hinge 31 to rotate, so that the sliding door switches from the open state to the second state;

[0081] When the side sliding door 2 is in the second state, the first motor further drives the first rotating shaft 313 to switch from the first position to the second position, thereby driving the side sliding door 2 to switch from the second state (parallel state) to the first state (inclined state);

[0082] When the side sliding door 2 is in the first state, the second driving mechanism 6 drives the second hinge 32 to rotate so that the side sliding door 2 switches from the first state to the closed state; when the side sliding door 2 is in the first state, the side sliding door 2 is inclined with respect to the door frame 1, and the second locking member 42 on the front side of the side sliding door 2 moves along, so that the side sliding door 2 and the door frame 1 are in a semi-locked state. Under the action of the guide portion 43, the second locking member 42 drives the side sliding door 2 to move along the guide portion 43 until the second locking member 42 reaches the locking portion 44, thereby realizing the locking fit of the first locking member 41 and the second locking member 42, that is, the side sliding door 2 and the door frame 1 are locked, thereby completing the door closing action.

[0083] Preferably, a first mounting groove 21 extending horizontally is provided in the middle portion of the inner side of the side sliding door 2 to receive a first connecting rod 34 that folds down when the side sliding door 2 is closed. A second mounting groove 12 is provided at the bottom of the door frame 1 for receiving the first connecting rod 34 that folds down when the side sliding door 2 is closed. The first and second mounting grooves 21, 12 are used to receive the folded first and second connecting rods 34, 35, thereby improving the rationality of the door structure.

[0084] The present invention further provides a car comprising: a side sliding door 2 device as described in any one of the above items, wherein the side sliding door 2 device can be installed on both the left and right sides of the car, or on only one side, without limitation.

[0085] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
