[0016] To open the door, the toggle button is toggled to slide the first slider relative to the base toward the second slider. As the rope passes through the first and second sliders and the pulleys on the base, the first slider, through the pulleys and ropes, drives the second slider toward the first slider, which then pulls the door lock cable to unlock the door. Simultaneously, the elastic member deforms under force, accumulating elastic potential energy. When the toggle button is released, the elastic member recovers its deformation, driving the first and second sliders away from each other, returning the toggle button to its original position. This completes the unlocking and automatic resetting of the door. By using the rope and pulley assembly to transmit the force applied by the toggle button to the first slider to the second slider, the power transmission process is smooth and flexible, making the door opening process even smoother. Furthermore, the first slider, second slider, elastic member, pulley assembly, rope, and seat can all be positioned on the outward-facing side of the door interior panel, with only one end of the dial button positioned on the inward-facing side. The dial button occupies less surface space on the door interior panel, minimizing the impact on the panel's design. Furthermore, compared to opening the door by rotating the interior door handle inward, positioning the seat and other structures of the interior door opening structure on the outward-facing side of the door interior panel only requires a narrow slit in the door interior panel for one end of the dial button to pass through. This makes the assembly gap between the dial button and the door interior panel easier to control, eliminates the need for a concave door interior panel, and substantially reduces the risk of dust accumulation.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0027] In addition, it should be noted that in the description of the present invention, it should be noted that the terminology nouns in each embodiment, such as "upper", "lower", "front", "back" and other words indicating direction, are only for simplifying the description of the positional relationship based on the drawings in the specification, and do not mean that the referred elements and devices must be operated in accordance with the specific directions and defined operations and methods and structures in the specification. Such direction nouns do not constitute a limitation on the present invention.

[0028] Herein, an XYZ axis is established, wherein the positive direction of the X axis represents the front of the vehicle, the negative direction of the X axis represents the right side of the vehicle, the positive direction of the Y axis represents the left side of the vehicle, the negative direction of the Y axis represents the right side of the vehicle, the positive direction of the Z axis represents the top of the vehicle, and the negative direction of the Z axis represents the bottom of the vehicle. It should be noted that the aforementioned X-axis, Y-axis, and Z-axis are merely for the purpose of facilitating the description of the present invention and simplifying the description, and 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 limiting the present invention.

[0029] like Figure 3 、 Figure 4 and Figure 6As shown, an inner opening structure of a vehicle door according to an embodiment of the present invention includes a dial button 1, a first slider 2, a second slider 3, an elastic member 4, a pulley group 5, a rope 6 and a seat body 7, wherein the first slider 2 and the second slider 3 are both slidably arranged on the seat body 7, one end of the dial button 1 is connected to the first slider 2, and the second slider 3 is connected to the door lock cable 10, the pulley group 5 includes a plurality of pulleys, and the plurality of pulleys are respectively arranged on the first slider 2, the second slider 3 and the seat body 7, and the rope 6 passes around each pulley in turn; the dial button 1 is used to drive the first slider 2 to move relative to the seat body 7 toward the direction close to the second slider 3, so that the second slider 3 moves toward the direction close to the first slider 2 under the pull of the rope 6 and pulls the door lock cable 10; the elastic member 4 is deformed by force when the second slider 3 moves toward the direction close to the first slider 2, and drives the first slider 2, the second slider 3 and the dial button 1 to reset when the dial button 1 is released.

[0030] Specifically, the toggle button 1 can move in the direction indicated by the X-axis, i.e., the front-to-back direction of the vehicle. The end of the toggle button 1, away from the connection with the first slider 2, is used to apply a toggle force. The first slider 2 and the second slider 3 can be spaced apart along the X-axis. The elastic member 4 can be a spring. The base 7 provides support for the first slider 2, the second slider 3, and the pulley assembly 5. The axes of the pulleys of the pulley assembly 5 can be along the Y-axis. The number of pulleys provided is not limited and can be flexibly arranged according to needs.

[0031] In this embodiment, when the door needs to be opened, the dial button 1 is toggled to slide the first slider 2 relative to the base 7 toward the second slider 3. Since the rope 6 passes through the pulleys on the first and second sliders 2 and 3 and the base 7, the first slider 2, through the pulleys of the pulley assembly 5 and the rope 6, drives the second slider 3 toward the first slider 2, thereby pulling the door lock cable to unlock the door. At the same time, the elastic member 4 is deformed by the force, and the elastic member 4 accumulates elastic potential energy. When the dial button 1 is released, the elastic member 4 recovers its deformation, driving the first and second sliders 2 and 3 away from each other, returning the dial button 1 to its original position. In this way, the door is unlocked and automatically reset. By using the rope 6 and the pulley assembly 5 to transmit the force applied by the dial button 1 to the first slider 2 to the second slider 3, the power transmission process is relatively smooth and flexible, and the door opening process is smoother. In addition, the first slider 2, the second slider 3, the elastic member 4, the pulley set 5, the rope 6 and the seat body 7 and other structures can be arranged on the side of the door interior panel facing the outside of the vehicle, and only one end of the dial button 1 is located on the side of the door interior panel facing the inside of the vehicle. The space occupied by the dial button 1 on the surface of the door interior panel is small, and the impact on the shape of the door interior panel is small; and compared with the method of opening the door by rotating the door opening handle toward the inside of the vehicle, when the seat body 7 and other structures of the door opening structure are arranged on the side of the door interior panel facing the outside of the vehicle, it is only necessary to open a long and narrow gap on the door interior panel for one end of the dial button 1 to pass through. The assembly gap between the dial button 1 and the door interior panel is easier to control, and there is no need to make the door interior panel into a concave structure, and basically no dust accumulation will occur.

[0032] like Figure 3 As shown, optionally, the multiple pulleys include at least one first movable pulley 51, multiple second movable pulleys 52 and multiple fixed pulleys 53, the number of the first movable pulleys 51 is less than the number of the second movable pulleys 52, the first movable pulley 51 is arranged on the first slider 2, the second movable pulley 52 is arranged on the second slider 3, the fixed pulley 53 is arranged on the seat body 7 and is located on the side of the first slider 2 away from the second slider 3, one end of the rope 6 is fixed to the first fixed point of the seat body 7, and the other end of the rope 6 is fixed to the second fixed point of the seat body 7 after passing through the first movable pulley 51, the second movable pulley 52 and the fixed pulley 53.

[0033] Specifically, fixed posts can be provided at the first and second fixed points of the base 7, and fixed rings can be provided at the ends of the rope 6. The fixed rings are sleeved onto the fixed posts, thereby achieving a fixed connection between the ends of the rope 6 and the base 7. The axis of the fixed pulley 53 is fixed and can be used to change the direction of the rope 6, that is, the direction of the force. The axes of the first movable pulley 51 and the second movable pulley 52 are movable along with the first slider 2 and the second slider 3, respectively, which can reduce the force required to lift the load, and in this case, can reduce the toggle force applied to the toggle button 1.

[0034] The second slider 3, the first slider 2 and the fixed pulley 53 are arranged in sequence along the direction indicated by the X-axis. The first slider 2 is provided with a first mounting groove with an opening toward the side of the fixed pulley 53. The first movable pulley 51 is installed in the first mounting groove. One first movable pulley 51 can be provided or multiple first movable pulleys 51 can be provided at intervals along the direction indicated by the Z-axis. The rope 6 can enter the first mounting groove from the notch of the first mounting groove and extend from the notch of the first mounting groove after bypassing the first movable pulley 51. A wire hole for the rope 6 to pass through can also be provided on the first slider 2. The second slider 3 is provided with a second mounting groove with an opening toward the first slider 2. The second movable pulley 52 is installed in the second mounting groove. The second movable pulley 52 and the fixed pulley 53 can be provided at intervals along the direction indicated by the Z-axis. The rope 6 can enter the second mounting groove from the notch of the second mounting groove and extend from the notch of the second mounting groove after bypassing the second movable pulley 52. Among them, each first movable pulley 51 is fixed on the first slider 2, and the moving distance of each first movable pulley 51 is equal, which is equal to the moving distance of the first slider 2, that is, the dial button 1. Each second movable pulley 52 is fixed on the second slider 3, and the moving distance of each second movable pulley 52 is equal, which is equal to the moving distance of the second slider 3.

[0035] Since the shaft of the second movable pulley 52 is fixed on the second slider 3, when the dial button 1 drives the first slider 2 to move to pull the rope 6, the two sections of rope 6 on both sides of each second movable pulley 52 simultaneously apply tension to the second slider 3, that is, the sum of the tension on the two sections of rope 6 on both sides of each second movable pulley 52 is equal to the total tension exerted on the second slider 3. By reasonably setting the number of second movable pulleys 52, only a small tension needs to be applied to each section of rope 6 to drive the second slider 3 to move. In other words, only a small pulling force needs to be applied to the dial button 1 to pull the door lock cable to open the car door.

[0036] Furthermore, since the shaft of the first movable pulley 51 is fixed to the first slider 2, when the dial button 1 drives the first slider 2 to move in the direction close to the second slider 3, the two sections of rope 6 on both sides of each first movable pulley 51 are extended, and the two sections of rope 6 on both sides of each second movable pulley 52 are shortened. Under the condition that the total length of the rope 6 remains unchanged, the sum of the extension of the two sections of rope 6 on both sides of each first movable pulley 51 is equal to the sum of the shortening of the two sections of rope 6 on both sides of each second movable pulley 52. ​​Although the moving distance of each first movable pulley 51 can be reduced by increasing the number of first movable pulleys 51, that is, reducing the length of the first slider 2, the and the moving distance of the dial button 1, but since the axes of the first movable pulleys 51 are fixed on the first slider 2, the force applied by the dial button 1 to the first slider 2 will be increased. If the friction between the axles of the movable and fixed pulleys is ignored, when the number of the first movable pulleys 51 is increased to be equal to the number of the second movable pulleys 52, the force applied to the dial button 1 is equal to the tension exerted on the second slider 3, and the pulley group 5 does not save effort. When the number of the first movable pulleys 51 is less than the number of the second movable pulleys 52, the moving distance of the dial button 1 can be reduced while ensuring that the dial button 1 is moved with effort, thereby achieving convenient opening of the car door.

[0037] like Figure 3 As shown, optionally, one first movable pulley 51 is provided, two second movable pulleys 52 are provided, and two fixed pulleys 53 are provided. The base body 7 is respectively provided with the first fixed point and the second fixed point on both sides of the two fixed pulleys 53. The end of the rope 6 away from the first fixed point is fixed to the second fixed point after passing through one of the second movable pulleys 52, one of the fixed pulleys 53, the first movable pulley 51, the other fixed pulley 53 and the other second movable pulley 52 in sequence.

[0038] In this embodiment, the number of the first movable pulley 51 is set to one, the number of the second movable pulley 52 is set to two, and the number of the fixed pulley 53 is set to two. The overall structure of the pulley group 5 is relatively simple and can meet the layout requirements in a smaller space. Figure 3 As shown, one end of the rope 6 is fixed to the first fixed point on the base 7, and the other end is fixed to the second fixed point on the base 7 after passing through one of the second movable pulleys 52, one of the fixed pulleys 53, the first movable pulley 51, the other fixed pulley 53 and the other second movable pulley 52 in sequence. The arrangement of the pulleys of the pulley group 5 is relatively symmetrical, or in other words, the entire pulley group 5 can be arranged symmetrically about the symmetry plane of the first movable pulley 51. The various sections of the rope 6 are subjected to relatively uniform force, and the movement of the first slider 2 and the second slider 3 is more stable.

[0039] In some other embodiments, one end of the rope 6 is fixed to the first fixed point of the seat body 7, and the other end can be fixed to the second fixed point of the seat body 7 after passing through the first movable pulley 51, one of the fixed pulleys 53, one of the second movable pulleys 52, another fixed pulley 53 and another second movable pulley 52 in sequence.

[0040] In some other embodiments, two first movable pulleys 51 may be provided, three or more second movable pulleys 52 may be provided, and an appropriate number of fixed pulleys 53 may be provided as needed.

[0041] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, optionally, the interior of the seat body 7 is hollow, and the first slider 2, the second slider 3, the elastic member 4, the pulley group 5 and the rope 6 are all placed inside the seat body 7; a first slide groove 71 is provided on the side wall of the seat body 7 facing the interior of the vehicle, one end of the dial button 1 passes through the first slide groove 71 to be connected to the first slider 2, and the dial button 1 is used to slide along the first slide groove 71.

[0042] Specifically, the seat body 7 can be a frame-type structure with a hollow interior, such as Figure 5 As shown, the frame structure can be open on one side facing the outside of the vehicle to reduce material usage. The first slider 2, the second slider 3, the elastic member 4, the pulley assembly 5, and the rope 6 are integrated into the interior of the base 7 to prevent the corresponding components from being exposed and to protect the corresponding components.

[0043] The seat body 7 can be embedded in the door interior panel, and one wall of the seat body 7 facing the interior of the vehicle is a plane wall. Compared with the existing concave handle box, it can avoid dust accumulation and basically eliminates the problem of dust cleaning. A first slide groove 71 extending in the direction indicated by the X-axis is provided on the plane wall. The length of the first slide groove 71 can be set according to the sliding stroke of the dial button 1. One end of the dial button 1 passes through the first slide groove 71 to be connected to the first slider 2. The first slide groove 71 can guide the movement of the dial button 1 so that the dial button 1 can slide along the first slide groove 71 to smoothly pull the door lock cable.

[0044] like Figure 1 and Figure 6 As shown, optionally, the door opening structure further includes a lighting assembly 8, which is arranged on the side of the seat body 7 facing the interior of the vehicle, and a second slide groove 81 corresponding to the first slide groove 71 is provided on the lighting assembly 8, and one end of the dial button passes through the second slide groove 81 and the first slide groove 71 in sequence to extend into the interior of the seat body 7.

[0045] Specifically, the light assembly 8 can be an indicator light assembly that emits relevant indication signals, such as illuminating a light when the dial button 1 is moved; it can also be an ambient light assembly that enhances the interior ambiance; or it can be an illumination light assembly that provides interior lighting. The light assembly 8 is fixedly connected to the side of the base 7 facing the interior of the vehicle. The dial button 1 can pass through the second slot 81 on the light assembly 8 and the first slot 71 on the base 7 to connect with the first slider 2. The second slot 81 can extend in the same direction as the first slot 71 and serves as a guide for the dial button 1.

[0046] In this embodiment, the lighting assembly 8 is integrated into the door opening structure, so that the door opening structure can not only open the door, but also serve as an indication, lighting or enhance the atmosphere inside the vehicle, thereby realizing the functional diversity of the door opening structure.

[0047] like Figure 1 As shown, optionally, the lighting assembly 8 includes a light-emitting part 82 and a circuit part that are interconnected, the light-emitting part 82 is a strip light strip, the extension direction of the strip light strip is consistent with the sliding direction of the dial button 1, the circuit part has a sliding resistor, the slider of the sliding resistor is connected to the dial button 1, and the strip light strip is used to adjust the lighting length as the dial button 1 moves.

[0048] Specifically, the lighting assembly 8 also includes a lamp holder, on which the light-emitting portion 82 and the circuit portion are both disposed, and a second slide groove 81 may be provided on the lamp holder. The light-emitting portion 82 is connected to the circuit portion so that the light-emitting portion is powered by the circuit portion, so that the light-emitting portion 82 can be illuminated. The light-emitting portion 82 may be a strip light strip extending in the direction indicated by the X-axis or in the sliding direction of the dial button 1. The length of the strip light strip may be set to be consistent with the movement stroke of the dial button 1. By moving the slider of the sliding rheostat of the circuit portion, the power supply current of the circuit portion to the strip light strip may be adjusted, thereby enabling the strip light strip to illuminate different lengths to meet signal indication requirements.

[0049] In this embodiment, by connecting the slider of the sliding rheostat of the lighting assembly 8 to the dial button 1, when the dial button 1 moves to open the car door, the slider of the sliding rheostat is driven to move, so that the strip light strip is lit at different lengths, realizing the linkage between the opening of the car door and the lighting of the light strip. When the dial button 1 moves to the maximum stroke position, that is, when the car door is opened, the lighting length of the strip light strip can reach the maximum, which increases the fun of opening the car door and enhances the user experience of the passengers.

[0050] like Figure 1As shown, optionally, the seat body 7 and the light assembly 8 are arranged on the side of the door interior panel facing the outside of the vehicle, and the door interior panel is provided with a third slide groove corresponding to the second slide groove 81 and a light-transmitting hole corresponding to the light-emitting portion 82. One end of the dial button 1 passes through the third slide groove, the second slide groove 81 and the first slide groove 71 in sequence and is connected to the first slider 2. The third slide groove extends along the sliding direction of the dial button 1. The setting length of the third slide groove can be consistent with the moving stroke of the dial button 1, and the dial button 1 can slide along the third slide groove. The entire seat body 7 and the light assembly 8 are all arranged on the side of the door interior panel facing the outside of the vehicle, and only one end of the dial button 1 protrudes from the surface of the door interior panel, so that the surface integrity of the door interior panel is relatively good, and the light emitted by the light assembly 8 is emitted through the light-transmitting hole on the door interior panel.

[0051] Optionally, a mounting hole is provided on the door interior panel, and the seat body 7 is embedded in the mounting hole. With this installation method, the seat body 7 and the light assembly 8 can be easily removed from the door interior panel for inspection.

[0052] Optionally, at least one side wall of the seat body 7 is provided with a limiting portion 72, the limiting portion 72 extending in the same direction as the first sliding groove 71, the first slider 2 is provided with a first limiting engagement portion 21 matching the limiting portion 72, and the second slider 3 is provided with a second limiting engagement portion 31 matching the limiting portion 72. Specifically, limiting portions 72 extending in the sliding direction of the dial button 1 can be provided on multiple side walls of the seat body 7. The limiting portions 72 can be limiting grooves, and the first limiting engagement portion 21 and the second limiting engagement portion 31 can be limiting protrusions. Alternatively, the limiting portions 72 can be limiting protrusions, and the first limiting engagement portion 21 and the second limiting engagement portion 31 can be limiting grooves. The first slider 2 can slide in a directional manner under the cooperation of the corresponding limiting protrusions and limiting grooves, and the second slider 3 can also slide in a directional manner under the cooperation of the corresponding limiting protrusions and limiting grooves, thereby preventing the first slider 2 and the second slider 3 from shaking during the sliding process and ensuring stable and smooth door opening.

[0053] Optionally, the door opening structure further includes a guide member 9, which is disposed between the first slider 2 and the second slider 3, and the elastic member 4 is sleeved on the guide member 9, and the guide member 9 includes a guide shaft 91 and a guide cylinder 92 sleeved with each other, and one of the guide shaft 91 and the guide cylinder 92 is connected to the first slider 2, and the other is connected to the second slider 3.

[0054] Here, the guide shaft 91 and the guide cylinder 92 are both extended along the sliding direction of the dial button 1. One end of the guide shaft 91 and one end of the guide cylinder 92 are slidably mounted on each other. The other end of the guide shaft 91 is fixed to the second slider 3, and the other end of the guide cylinder 92 is fixed to the first slider 2. The guide shaft 91 can slide relative to the guide cylinder 92 to achieve sliding guidance of the first slider 2 and the second slider 3. The elastic member 4 is located between the first slider 2 and the second slider 3 and is mounted on the outside of the guide member 9, that is, it is mounted on the outside of the guide shaft 91 and the guide cylinder 92. The guide member 9 can be used to guide the elastic member 4 to prevent the elastic member 4 from shaking and becoming unstable during the compression deformation process. In some embodiments, the guide shaft 91 and the guide cylinder 92 can also be replaced by a first slide rail and a second slide rail that are slidably connected to each other.

[0055] In some other embodiments, the elastic member 4 may be arranged between the second slider 3 and the base 7. When the dial button 1 is turned and the first slider 2 and the second slider 3 move toward each other, the elastic member 4 undergoes stretching deformation. When the dial button 1 is released, the elastic member 4 recovers its deformation to drive the first slider 2, the second slider 3 and the dial button 1 to reset.
