DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] As people's living standards continue to improve, vehicles, such as cars, have gradually become popular in every household.

[0040] Among them, the vehicle generally includes a body with a driver's cabin. In order to facilitate the driver and passengers to enter and exit the driver's cabin, the body has a door opening connected to the driver's cabin, and a door is arranged at the door opening to isolate the vehicle from external interference and to reduce side impact to a certain extent to protect the driver and passengers.

[0041] In the related art, one side of the door is usually hinged to the vehicle body, and the door is opened and closed by rotating the door relative to the vehicle body. However, when such a door is opened, it will occupy a large space in the width direction of the vehicle, which can easily make the door unable to be opened in a narrow parking space, making it difficult for users to get on and off the vehicle. Moreover, after opening, the door will swing randomly, affecting the normal getting on and off of the vehicle by users, and posing a safety hazard.

[0042] Based on this, an embodiment of the present invention provides a vehicle, by arranging a translation mechanism between the vehicle body and the door, and arranging a driving member and a damping mechanism between the vehicle body and the translation mechanism, so that the driving member is used to drive the translation mechanism to drive the door to translate, so as to open or close the door. The damping structure is used to make the door hover at a preset position relative to the vehicle body after the door is opened, which can not only improve the convenience of users getting on and off the vehicle, but also improve the stability of the door after it is opened, thereby ensuring the safety of the user.

[0043] The vehicle provided by the present invention is described in detail below with reference to the accompanying drawings through specific embodiments:

[0044] Reference Figures 1 to 5 As shown, this embodiment provides a vehicle, including a vehicle body 1 and a vehicle door 2. The vehicle body 1 has a door opening 13, and the vehicle door 2 is located at the door opening 13.

[0045] A translation mechanism 3 is provided between the vehicle body 1 and the vehicle door 2, and a driving member 4 and a damping mechanism 5 are provided between the vehicle body 1 and the translation mechanism 3. The driving member 4 is used to drive the translation mechanism 3 to drive the vehicle door 2 to translate, so as to open or close the vehicle door 2. Specifically, the damping mechanism 5 is used to make the vehicle door 2 hover at a preset position relative to the vehicle body 1 after the vehicle door 2 is opened.

[0046] Exemplarily, the translation mechanism 3 drives the vehicle door 2 to translate, specifically, when the vehicle door 2 translates between the closed position and the open position, the angle of the exterior surface of the vehicle door 2 (i.e., the side facing the outside of the vehicle when the vehicle door 2 is closed) does not basically change, so that the exterior surface of the vehicle door 2 can always be located on the outside of the vehicle. In this way, when the user stands on the outside of the vehicle, no matter whether the vehicle door 2 is in an open state or a closed state, the user sees the exterior surface of the vehicle door 2.

[0047] Exemplary, specific reference Figure 2 As shown, the solid line shows the schematic diagram of the door 2 in the closed state, and the dotted line shows the schematic diagram of the door 2 in the open state. When the door 2 moves horizontally to open, Figure 2 The door 2 in the middle will have a tendency to move forward under the drive of the translation mechanism 3, and at the same time, it will have a tendency to move rightward during the forward movement, thereby realizing the translation opening of the door 2. When the door 2 moves to close, Figure 2 The door 2 in the middle has a tendency to move backwards, and at the same time has a tendency to move leftwards during the backward movement, thereby achieving translational closing of the door 2.

[0048] For example, when the vehicle is parked on a ramp, the door 2 can move from the high end to the low end of the ramp to gradually move from an open state to a closed state. By providing a damping mechanism 5, when the door 2 parked on the ramp is opened, the damping mechanism 5 can at least offset the external force such as the gravity of the door 2, thereby maintaining the open state of the door 2, so that the door 2 can hover at a preset position.

[0049] Exemplarily, the driving member 4 may include a driving motor, or the driving member 4 may include a cylinder, etc.

[0050] Among them, the driving member 4, such as the internal resistance of the driving motor when not working and the gravity of the translation mechanism 3 itself, can also cooperate with the damping mechanism 5 to a certain extent to overcome the external force to ensure the reliable suspension of the door 2.

[0051] The vehicle provided in this embodiment is provided with a translation mechanism 3 between the vehicle body 1 and the door 2, and a driving member 4 and a damping mechanism 5 are provided between the vehicle body 1 and the translation mechanism 3, so that the driving member 4 is used to drive the translation mechanism 3 to drive the door 2 to translate, so as to open or close the door 2, and the damping mechanism 5 is used to make the door 2 hover at a preset position relative to the vehicle body 1 after the door 2 is opened. In this way, during the opening and closing process of the door 2, the door 2 itself will not rotate, but will translate, so compared with the solution in which the door rotates, the space occupied by the door 2 in the width direction of the vehicle body 1 ( Figure 1 and Figure 2The space in the left and right directions (as shown in the figure) is sufficient to open the door 2 in a narrow parking space, making it convenient for users to get on and off the vehicle, improving the applicability of the vehicle and the user's experience. In addition, this can also prevent the door 2 from hitting pedestrians beside the vehicle when it is opened, thereby improving the safety when opening the door. Moreover, this arrangement makes the appearance surface of the door 2 (that is, the side facing the outside of the vehicle after the door 2 is closed) always face outward, that is, when the user stands outside the vehicle, no matter whether the door 2 is in an open state or a closed state, the user sees the appearance surface of the door 2, thereby realizing the adjustment of the opening and closing of the door 2 and improving the appearance of the entire vehicle to a certain extent. At the same time, by using the damping mechanism 5, after the door 2 is opened, the door 2 can be suspended at a preset position relative to the vehicle body 1. In this way, the damping mechanism 5 can realize the suspension of the door 2 at the preset position after opening. For example, when the vehicle is parked on a ramp, and the door 2 is in an open state at the high end of the ramp and in a closed state at the low end of the ramp, the damping mechanism 5 can at least offset the gravity and other external forces of the door 2, so as to avoid the accidental closing of the door 2 on the ramp due to gravity, etc. to a certain extent, and avoid the accidental swinging of the door 2 after opening to a certain extent, so that the door 2 can be kept open according to actual needs, which is convenient for users to get on and off the vehicle, and can ensure the safety of users, and is also conducive to improving the driving experience of users. In other words, the vehicle can not only improve the convenience of users getting on and off the vehicle, but also improve the stability of the door 2 after opening, ensuring the safety of users.

[0052] In some embodiments, reference Figure 2 As shown, the translation mechanism 3 has at least two first connection points 311 respectively connected to the vehicle body 1 for rotation and at least two second connection points 312 respectively connected to the vehicle door 2 for rotation. The lines connecting the at least two first connection points 311 and the at least two second connection points 312 together form a parallelogram structure.

[0053] That is, among all the first connection points 311, the connection lines between at least two first connection points 311, the connection lines between at least two second connection points 312, and the translation mechanism 3 can form a parallelogram together. This arrangement ensures that the door 2 can basically maintain translation under the drive of the translation mechanism 3, and will not tilt or fall, and can improve the stability of the door 2 during translation, and further ensure that the appearance surface of the door 2 always faces the outside of the vehicle during translation.

[0054] For example, at least two of all the first connection points 311 may be located on the translation plane of the door 2 (ie, Figure 2At the same time, it is also possible to make the projections of at least two of all the second connection points 312 not overlap in the translation plane of the door 2. For example, the line between the two first connection points 311 and the line between the two second connection points 312 can be arranged in parallel, so that it can be ensured that the above-mentioned parallelogram structure can always be formed in the translation plane of the door 2 during the entire translation process of the door 2.

[0055] In some embodiments, reference Figure 2 As shown, the translation mechanism 3 includes at least two swing arms 31 disposed at intervals. One end of each swing arm 31 has at least one first connection point 311, and the other end of each swing arm 31 has at least one second connection point 312. The damping mechanism 5 is connected between one of the swing arms 31 and the vehicle body 1.

[0056] In this way, at least within the translation plane of the vehicle door 2, a parallelogram structure can be formed between at least two swing arms 31. When the translation mechanism 3 drives the vehicle door 2 to translate, the vehicle door 2 has high stability and good balance.

[0057] For example, the drive member 4 may be connected to one of the swing arms 31 .

[0058] In some embodiments, reference Figures 2 to 4 As shown, the damping mechanism 5 includes a first connecting member 6, a second connecting member 7, and a damping structure 8 disposed between the first connecting member 6 and the second connecting member 7. The first connecting member 6 is connected to the vehicle body 1, and the second connecting member 7 is connected to the translation mechanism 3. The second connecting member 7 is movably connected to the first connecting member 6, so that the second connecting member 7 moves relative to the first connecting member 6 along a preset direction when the vehicle door 2 translates. The damping structure 8 is used to prevent the second connecting member 7 from moving after the vehicle door 2 is opened. The preset direction can be specifically Figure 3 and Figure 5 X direction shown.

[0059] For example, when the door 2 is opened, the second connecting member 7 moves relative to the first connecting member 6 driven by the door 2 to extend the entire damping structure 8. Similarly, when the door 2 is closed, the second connecting member 7 moves relative to the first connecting member 6 driven by the door 2 to shorten the entire damping structure 8. Therefore, when the relative positions of the first connecting member 6 and the second connecting member 7 are fixed, that is, when the length of the damping mechanism 5 is constant, the distance between the door 2 and the vehicle body 1 is relatively stable, thereby achieving the hovering of the door 2.

[0060] Through the above arrangement, after the vehicle door 2 is opened, the movement of the second connecting member 7 is prevented by the damping structure 8, that is, the stability of the relative positions of the first connecting member 6 and the second connecting member 7 after the vehicle door 2 is opened is guaranteed to a certain extent, thereby preventing the vehicle door 2 from driving the second connecting member 7 to move relative to the first connecting member 6 under the action of external forces such as gravity to a certain extent, thereby achieving the hovering of the vehicle door 2.

[0061] In some embodiments, reference Figures 3 to 5 As shown, an intermediate connecting member 9 is provided between the damping structure 8 and the second connecting member 7. The intermediate connecting member 9 can rotate around a preset direction when the second connecting member 7 moves. The damping structure 8 can prevent the intermediate connecting member 9 from rotating after the door 2 is opened, so that the second connecting member 7 stops moving.

[0062] In this arrangement, for example, after the vehicle door 2 is opened, the vehicle door 2 is subjected to external forces such as gravity, causing the second connecting member 7 to extend relative to the first connecting member 6 under the drive of the vehicle door 2. The moving force of the second connecting member 7 will form a rotational torque on the intermediate connecting member 9, and at least part of the rotational torque is overcome by the damping structure 8, that is, the damping force of the damping structure 8 can offset at least part of the rotational torque, thereby preventing the rotation of the intermediate connecting member 9 to a certain extent, and then preventing the movement of the second connecting member 7, so that the vehicle door 2 remains in the open state, and the vehicle door 2 is reliably suspended.

[0063] Exemplarily, when the vehicle door 2 is driven by the driving member 4 to move from a closed state to an open state, or when the vehicle door 2 moves from an open state to a closed state, the relative movement force between the second connecting member 7 and the first connecting member 6 applied to the translation mechanism 3 is smaller than the driving force applied by the driving member 4 to the translation mechanism 3, thereby allowing the vehicle door 2 to open normally under the driving action of the driving member 4.

[0064] In some embodiments, reference Figure 3 and Figure 4 As shown, the intermediate connecting member 9 has a second external thread 92, and the second connecting member 7 has a second internal thread hole matched with the second external thread 92, so that when the second connecting member 7 moves, the intermediate connecting member 9 will rotate.

[0065] Of course, the intermediate connecting member 9 may also have a second internal threaded hole, and the second connecting member 7 may have a second external thread matched with the second internal threaded hole.

[0066] In some embodiments, reference Figures 3 to 5 As shown, the intermediate connecting member 9 has a first friction member 91. The damping structure 8 includes a friction assembly 81, and the friction assembly 81 includes a second friction member 811 located at least on one side of the first friction member 91 in the axial direction. The second friction member 811 is relatively fixed on the first connecting member 6 and fits with the first friction member 91.

[0067] In this way, when the intermediate connecting member 9 rotates, the first friction member 91 will rotate synchronously with the intermediate connecting member 9, and the existence of the second friction member 811 can generate damping friction force with the first friction member 91. After the driving member 4 stops working and the vehicle door 2 is opened, the friction force is greater than the rotational torque of the intermediate connecting member 9. The friction force can offset at least part of the rotational torque on the first friction member 91 and the intermediate connecting member 9 to prevent the intermediate connecting member 9 from rotating. This can avoid the accidental relative movement of the first connecting member 6 and the second connecting member 7 to a certain extent, thereby achieving the hovering of the vehicle door 2.

[0068] In some embodiments, reference Figures 3 to 5 As shown, the intermediate connecting member 9 has a first external thread, and the first friction member 91 has a first internal thread hole 911 that matches the first external thread.

[0069] In this way, the connection between the intermediate connecting member 9 and the first friction member 91 is achieved through the cooperation of the first external thread and the first internal threaded hole 911, so that the rotational torque on the intermediate connecting member 9 can be offset to a certain extent through the friction force between the second friction member 811 and the first friction member 91, thereby achieving the hovering of the vehicle door 2.

[0070] Of course, in other implementations, the first friction member 91 may be provided with a first external thread, and the intermediate connecting member 9 may be provided with a first internal threaded hole.

[0071] Exemplarily, when the driving member 4 is controlled to drive the translation mechanism 3 to drive the vehicle door 2 to translate so that the vehicle door 2 is opened or closed, the rotational torque applied by the vehicle door 2 to the intermediate connecting member 9 is at least greater than the friction force between the second friction member 811 and the first friction force, so that the vehicle door 2 can be opened and closed.

[0072] Exemplarily, the surface roughness of the second friction member 811 may be greater than the surface roughness of the first friction member 91 , so that frictional force can be generated between the second friction member 811 and the first friction member 91 .

[0073] Exemplarily, the first friction member 91 may be a metal washer or a plastic washer.

[0074] In some embodiments, reference Figures 4 to 5 As shown, there are at least two first friction members 91, and at least two first friction members 91 are arranged at intervals along the axial direction of the intermediate connecting member 9. Both sides of each first friction member 91 in the axial direction have second friction members 811. Figure 3 and Figure 5 In the X direction.

[0075] Such an arrangement can increase the friction between the friction assembly 81 and the intermediate connecting member 9 to a certain extent, thereby facilitating further ensuring a good offset of the rotational torque on the intermediate connecting member 9, thereby further ensuring a reliable suspension of the vehicle door 2.

[0076] In some embodiments, the friction assembly 81 further includes a third friction member 812 located on the side of the second friction member 811 away from the first friction member 91. The third friction member 812 is relatively fixed to the first connecting member 6, and the second friction member 811 is sandwiched between the first friction member 91 and the third friction member 812.

[0077] In this way, when the intermediate connecting member 9 rotates, the second friction member 811 can generate friction with the first friction member 91 to prevent the first friction member 91 from rotating. At the same time, when the second friction member 811 is subjected to force and has a tendency to rotate, the third friction member 812 will also generate friction with the second friction member 811 to increase the friction force applied by the second friction member 811 to the first friction member 91, thereby further preventing the first friction member 91 and the intermediate connecting member 9 from rotating, thereby making the door 2 more reliably suspended. In addition, this can save the space occupied by the friction assembly 81 and the first friction member 91, make good use of the space of the damping structure 8, and realize the miniaturization of the damping structure 8 while realizing the reliable suspension of the door 2.

[0078] Exemplarily, when the driving member 4 is controlled to drive the translation mechanism 3 to drive the vehicle door 2 to translate so that the vehicle door 2 is opened or closed, the rotational torque applied by the vehicle door 2 to the intermediate connecting member 9 is greater than the total friction force applied by the second friction member 811 to the first friction member 91, so that the vehicle door 2 can be opened and closed.

[0079] In some embodiments, reference Figures 4 to 5 As shown, the damping structure 8 also includes an elastic member 82 and a housing 83 connected to the first connecting member 6. The friction assembly 81 and the elastic member 82 are both located in the housing 83, the friction assembly 81 is connected between one side of the housing 83 along a preset direction and one end of the elastic member 82, and the other end of the elastic member 82 is connected to the other side of the housing 83 along the preset direction.

[0080] With such a configuration, the elastic member 82 and the housing 83 can at least apply a squeezing force to the first friction member 91 and the second friction member 811, thereby facilitating the increase of the friction force between the first friction member 91 and the second friction member 811, and further facilitating the improvement of the offset effect on the rotational torque, thereby ensuring the reliable suspension of the vehicle door 2. In addition, by replacing the elastic member 82 with different stiffness coefficients and / or the first friction members 91 with different numbers, etc., the reverse force of the friction assembly 81 on the intermediate connecting member 9 can be adjusted, thereby adjusting the offset degree of the rotational torque on the intermediate connecting member 9 by the friction assembly 81, so as to meet different usage requirements.

[0081] Exemplarily, the elastic member 82 may be a spring, or may also be an elastic rope, an elastic strip, etc.

[0082] In some embodiments, reference Figure 5 As shown, the third friction member 812 is provided with a plug-in portion 813 extending in a direction perpendicular to the preset direction, and the housing 83 is provided with a plug-in slot for the plug-in portion 813 to extend into. The direction perpendicular to the preset direction can be specifically Figure 5 Y direction shown.

[0083] Such an arrangement can improve the position stability of the third friction member 812 along the preset direction to a certain extent, thereby facilitating the friction force between the first friction member 91 and the third friction member 812 , and ensuring the damping force applied by the damping structure 8 to the intermediate connecting member 9 .

[0084] Of course, a plug-in portion may be provided on the housing 83 , and a plug-in groove may be provided on the second friction member 811 .

[0085] In some embodiments, reference Figures 4 to 5 As shown, the housing 83 includes a shell 831 and a cover 832, which are detachably connected and together enclose a receiving cavity, in which the friction component 81 and the elastic component 82 are both located, and the cavity wall of the receiving cavity has an avoidance hole for at least the first friction component 91 to cooperate with the friction component 81.

[0086] With such a configuration, the friction assembly 81 and the elastic member 82 can be protected to a certain extent by the accommodating cavity, so that the damping force applied by the friction assembly 81 to the intermediate connecting member 9 can be ensured, and the door 2 can be suspended. In addition, since the shell 831 and the cover 832 are detachably connected, it is convenient to repair and replace the friction assembly 81, the elastic member 82, etc. On the other hand, when one of the shell 831 and the cover 832 is damaged, only the damaged part needs to be replaced, thereby avoiding the scrapping of the shell 831 and the cover 832 as a whole, and reducing the cost of repair and use.

[0087] Exemplarily, the shell 831 and the cover 832 may be connected by threaded engagement, or the shell 831 and the cover 832 may be connected by snap fastening or the like.

[0088] For example, refer to Figure 4 As shown, a bearing 10 can be provided on the side of the shell 831 away from the cover body 832, and the bearing 10 can be fixed to the first connecting member 6. The intermediate connecting member 9 can be passed through the inner ring of the bearing 10 to make the first friction member 91 and the second friction member 811 fit together, so that the bearing 10 can improve the smoothness of the rotation of the intermediate connecting member 9.

[0089] Exemplarily, a bearing retaining ring may be provided between the bearing 10 and the housing 831 to limit the position of the bearing 10 .

[0090] In some embodiments, reference Figure 3 As shown, the first connecting member 6 has a first sliding portion 631 , and the second connecting member 7 has a second sliding portion 721 . The first sliding portion 631 and the second sliding portion 721 cooperate to guide the movement of the second connecting member 7 .

[0091] With such arrangement, through the cooperation of the first sliding portion 631 and the second sliding portion 721, the stability and reliability of the second connecting member 7 and the first connecting member 6 during movement can be improved to a certain extent, thereby facilitating the reliable extension and retraction of the damping mechanism 5, thereby facilitating the opening or closing of the vehicle door 2.

[0092] In some embodiments, the first sliding portion 631 is a slide groove extending along a preset direction, and the second sliding portion 721 is a protrusion. The protrusion extends into the slide groove and can move along the slide groove. In this way, the first connecting member 6 and the second connecting member 7 can be reliably moved by the movement of the protrusion along the slide groove, so that the damping mechanism 5 has good telescopic stability.

[0093] Of course, in other implementations, the second sliding portion 721 may be a sliding groove, and the first sliding portion 631 and the second sliding portion 721 may be protrusions.

[0094] In some embodiments, reference Figure 3 and Figure 4 As shown, the first connecting member 6 has a receiving cavity 61 opening toward the second connecting member 7 , the damping mechanism 5 and part of the second connecting member 7 are both located in the receiving cavity 61 , and the second connecting member 7 can reciprocate along the receiving cavity 61 .

[0095] In this way, the damping mechanism 5 and the second connecting member 7 can be protected to a certain extent through the accommodating cavity 61, which is conducive to ensuring the damping effect and realizing the stable suspension of the vehicle door 2. In addition, this can also ensure to a certain extent that the second connecting member 7 moves to drive the vehicle door 2 to open and close reliably relative to the vehicle body 1, thereby improving the user experience.

[0096] In some embodiments, reference Figure 3 and Figure 4 As shown, the first connecting member 6 includes a first main body 62 and a guide tube 63 which are detachably connected. The first main body 62 is connected to the vehicle body 1 , and the inner cavity of the guide tube 63 is formed to at least partially accommodate the cavity 61 .

[0097] In this way, when one of the first body 62 and the guide tube 63 is damaged, only the damaged part needs to be replaced, thereby avoiding the scrapping of the first body 62 as a whole to a certain extent, which is conducive to saving maintenance and use costs.

[0098] Exemplarily, the first body 62 and the guide tube 63 may be detachably connected by threaded engagement, or may be connected by snap-fit.

[0099] Exemplarily, the first sliding portion 631 may be disposed on the guide tube 63 .

[0100] The first body 62 may include a first ball socket, and the vehicle body 1 has a first matching hole, the first ball socket extends into the first matching hole, and can rotate in the first matching hole.

[0101] Reference Figure 3 As shown, the second connecting member 7 includes a second main body 71 connected to the vehicle door 2 and a nut member 72 integrally formed with the second main body 71. The nut member 72 has the second internal thread hole, and the outer periphery of the intermediate connecting member 9 has the second external thread 92.

[0102] This makes the overall structural strength of the second main body 71 and the nut member 72 high, so that the nut member 72 and the intermediate connecting member 9 can be reliably matched, so that the second connecting member 7 can stably extend and retract relative to the first connecting member 6 to realize the opening and closing of the vehicle door 2, and can also ensure the stable suspension of the vehicle door 2.

[0103] Exemplarily, the second body 71 may be integrally formed with the nut member 72 by injection molding.

[0104] For example, refer to Figure 3 As shown, the second body 71 may include a body portion 711 and a sleeve 712 riveted together, and the body portion 711 is connected to the vehicle door 2. The nut member 72 is integrally formed at one end of the sleeve 712.

[0105] Exemplarily, the sleeve 712 can be extended into the inner cavity of the guide tube 63 , and the intermediate connector 9 can be threadedly matched with the nut member 72 and extend into the inner cavity of the sleeve 712 through the inner cavity of the nut member 72 .

[0106] The main body portion 711 may include a second ball socket, and the vehicle door 2 has a second matching hole, the second ball socket extends into the second matching hole, and can rotate in the second matching hole.

[0107] In some embodiments, reference Figure 1As shown, the vehicle includes an A-pillar 11 and a C-pillar 12, and a door opening 13 is provided between the A-pillar 11 and the C-pillar 12 on the same side in the width direction of the vehicle. There are two doors 2, which are arranged at the door opening 13 along the length direction of the vehicle, and the two doors 2 move in opposite directions when opened or closed. The length direction of the vehicle can be specifically Figure 1 and Figure 2 Front-to-back orientation shown.

[0108] In this way, the B-pillar on the vehicle can be eliminated, and the area of ​​the door opening 13 between the A-pillar 11 and the C-pillar 12 can be effectively increased, making it easier for users or large-sized cargo to get on and off the vehicle, and providing a better driving experience.

[0109] Among them, refer to Figure 1 As shown, the two doors 2 move in opposite directions when opened or closed, which can be understood as follows: the door 2 near the A-pillar 11 (which can be the front door on the passenger compartment side, or the front door on the driver compartment side) moves in a direction close to the front of the vehicle when opened, and moves in a direction close to the rear of the vehicle when closed. The door 2 near the C-pillar 12 moves in a direction close to the rear of the vehicle when opened, and moves in a direction close to the front of the vehicle when closed.
