[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] Reference below Figure 1-Figure 7 A door driving mechanism 100 for a vehicle according to an embodiment of the present invention is described.

[0033] like Figure 1-Figure 7 As shown, the vehicle door driving mechanism 100 according to the embodiment of the present utility model comprises: a housing 10 , a driving member 20 and a pushing member 30 .

[0034] The housing 10 is suitable for being arranged on a door 40 of a vehicle, and the housing 10 defines a first accommodation space 11 with one end open. Figure 7As shown, the housing 10 can be disposed on a vehicle door sheet metal 401. For example, the vehicle door sheet metal 401 can be provided with a matching hole, and the housing 10 can be disposed in the matching hole of the vehicle door sheet metal 401 by screwing or clamping. The housing 10 defines a first accommodation space 11, one end of which is open. As some embodiments of the present application, the first accommodation space 11 is open toward the vehicle body (e.g., the side panel) of the vehicle.

[0035] At least part of the driving member 20 and at least part of the pushing member 30 are disposed in the first accommodation space 11. As some embodiments of the present application, refer to Figure 4 As shown, part of the structure of the driving member 20 can be arranged in the first accommodating space 11, and part of the structure of the pushing member 30 can be arranged in the first accommodating space 11. As some embodiments of the present application, under certain working conditions of the vehicle door driving mechanism 100, the overall structure of the driving member 20 and the overall structure of the pushing member 30 can be located in the first accommodating space 11.

[0036] The driving member 20 is connected to the pushing member 30 in a transmission connection. The driving member 20 can drive the pushing member 30 to move along a first direction of the door driving mechanism 100 (i.e., an axial direction of the door driving mechanism 100, i.e., Figure 4 The driving member 20 can drive the push member 30 to move along the first direction (ie, the X direction) of the door driving mechanism 100 toward the vehicle body. Figure 4 The X direction shown) moves toward the side of the vehicle.

[0037] As some embodiments of the present application, a portion of the structure of the driving member 20 may be along the first direction (ie, Figure 4 In some embodiments of the present application, the driving member 20 can be partially rotated, and when the driving member 20 is partially rotated, it can drive the pushing member 30 to move along the first direction (i.e., the X direction) of the door driving mechanism 100. Figure 4 X direction) movement.

[0038] As some embodiments of the present application, the driving member 20 can drive the pushing member 30 to move along the first direction (ie, Figure 4 The driving member 20 moves the pusher 30 toward the vehicle body (e.g., the side panel) to make the pusher 30 contact the vehicle body (e.g., the side panel). After the pusher 30 contacts the vehicle body (e.g., the side panel), the driving member 20 continues to drive the pusher 30 along the first direction (i.e., the first direction) of the door driving mechanism 100. Figure 4Since the housing 10 is disposed on the door sheet metal 401, under the action of the driving member 20 and the pushing member 30, the door driving mechanism 100 can drive the door 40 to move in a direction away from the vehicle body (such as the side panel) so that the door 40 is opened at a certain angle. In this way, the user does not need to pull the door handle disposed on the outside of the door 40 to open the door 40, so that the door handle structure on the outside of the door 40 can be omitted, which can reduce the wind resistance of the vehicle when driving.

[0039] As some embodiments of the present application, the user can send a door opening signal in various ways, so that the driving member 20 drives the pushing member 30 to move along the first direction (i.e., Figure 4 For example, the user may send a door opening signal by, but not limited to, touching the sensing area on the outer surface of the door 40, operating the remote control key, or pressing the door opening button on the outer side of the door 40. The vehicle controller may receive the door opening signal and control the lock body of the door 40 to unlock according to the door opening signal. After the lock body of the door 40 is unlocked, the vehicle controller may control the driving member 20 to work so that the driving member 20 drives the pushing member 30 to move along the first direction (i.e., Figure 4 The vehicle door 40 is moved in the X direction (shown in the X direction) toward the vehicle body (e.g., the side panel) to move the vehicle door 40 in a direction away from the vehicle body (e.g., the side panel). In some embodiments of the present application, after the vehicle door 40 moves in the direction away from the vehicle body (e.g., the side panel), the user can manually adjust the vehicle door 40 to a position that facilitates entry and exit of the passenger compartment.

[0040] As some optional embodiments of the present application, it is possible to pre-set so that the driving member 20 drives the pushing member 30 to move along the first direction (i.e. Figure 4 After the first preset time of movement of the door 40 (in the X direction shown), the driving member 20 drives the pushing member 30 to reset. As some optional embodiments of the present application, it can be preset that after the lock body of the door 40 is controlled to unlock for a second preset time, the driving member 20 drives the pushing member 30 to reset.

[0041] Therefore, through the door drive mechanism 100 of the present application, the driving member 20 can drive the pushing member 30 to move so that the pushing member 30 abuts against the body of the vehicle to open the door 40, thereby omitting the door handle structure on the outside of the door 40, which is beneficial to reducing the wind resistance of the vehicle during driving, reducing the energy consumption of the vehicle, improving the fuel economy of fuel vehicles, and improving the driving range of electric vehicles.

[0042] In some embodiments of the present invention, Figure 2 and Figure 4As shown, the driving member 20 may include a driving body 21 and a first matching member 22, and the driving body 21 and the first matching member 22 may be arranged in transmission connection. The pushing member 30 may include a pushing body 31 and a second matching member 32, and the pushing body 31 and the second matching member 32 may be arranged in connection, and the first matching member 22 may be arranged in transmission connection with the second matching member 32.

[0043] As some embodiments of the present application, the driving body 21 can be configured as a motor, the first matching piece 22 can be configured as a screw, the second matching piece 32 can be configured as a nut, the nut can be threadedly connected to the screw, the driving shaft of the motor can be connected to the screw, or the driving shaft of the motor itself can be configured as a screw, and the screw can be driven by the motor to rotate, so as to drive the nut along the axial direction of the first matching piece 22 (i.e. Figure 4 The push member 30 can be driven to move along the first direction (i.e., the X direction) of the door driving mechanism 100. Figure 4 It can be understood that the axial direction of the first matching member 22 is parallel to the first direction of the door driving mechanism 100.

[0044] Such an arrangement can drive the pushing member 30 to move along the first direction of the vehicle door drive mechanism 100 through the driving member 20, and through the cooperation of the first matching member 22 and the second matching member 32, the driving member 20 can drive the pushing member 30 to move smoothly and reliably, thereby helping to improve the working reliability of the vehicle door drive mechanism 100.

[0045] As some embodiments of the present application, the second mating piece 32 can be integrally formed with the pushing body 31, that is, the second mating piece 32 and the pushing body 31 can be constructed as an integral piece. Such a configuration can improve the connection strength between the second mating piece 32 and the pushing body 31.

[0046] In some embodiments of the present invention, Figure 4 As shown, the pushing body 31 may define a second accommodating space 311, the second accommodating space 311 may be openly arranged toward the first accommodating space 11, and a part of the structure of the first matching member 22 may be located in the second accommodating space 311. As some embodiments of the present application, the second matching member 32 may be located in the second accommodating space 311, and a part of the structure of the first matching member 22 may be located in the second accommodating space 311 and be transmission-connected with the second matching member 32. Such an arrangement may make the arrangement of the driving member 20 and the pushing member 30 compact, which is beneficial to reducing the volume of the door driving mechanism 100, thereby helping to reduce the difficulty of arranging the door driving mechanism 100.

[0047] In some embodiments of the present invention, Figure 4As shown, the housing 10 may include a housing body 12 and a mounting flange 13, and the housing body 12 and the mounting flange 13 may be connected and arranged. Figure 4 As shown, the shell body 12 can define a first accommodating space 11 with one end open, and the mounting flange 13 can be arranged on the inner side of the shell body 12. The mounting flange 13 can open the first accommodating space 11 along the first direction (i.e. Figure 4 The driving body 21 can be disposed in the first sub-accommodating space 111 and the second sub-accommodating space 112 .

[0048] Such an arrangement can separate the driving body 21 from other components (such as the pushing member 30) by installing the flange 13, thereby preventing other components (such as the pushing member 30) from hitting the driving body 21, thereby providing a safe working environment for the driving body 21. In addition, the installation flange 13 can also stop the driving body 21 to prevent the driving body 21 from moving, thereby improving the reliability of the door drive mechanism 100.

[0049] As some embodiments of the present application, the mounting flange 13 can be integrally formed with the shell body 12 , that is, the mounting flange 13 and the shell body 12 can be constructed as an integral piece. Such a setting can improve the connection strength between the mounting flange 13 and the shell body 12 .

[0050] In some embodiments of the present invention, Figure 4 As shown, the mounting flange 13 may have a mounting hole 131, and the mounting hole 131 may be formed along the thickness direction of the mounting flange 13 (i.e. Figure 4 The X direction shown in the figure) is arranged through the mounting flange 13, that is, the mounting hole 131 can be configured as a through hole, and the drive body 21 can be assembled with the mounting hole 131. As some embodiments of the present application, refer to Figure 4 As shown, the number of the mounting holes 131 can be set to be multiple. As some embodiments of the present application, a connecting member (such as but not limited to a bolt, a screw, etc.) can pass through the mounting hole 131 and connect to the drive body 21 to match and assemble the drive body 21 with the mounting hole 131. In this way, the drive body 21 can be firmly installed in the first sub-accommodating space 111, and the installation firmness of the drive body 21 can be improved.

[0051] In some embodiments of the present invention, Figure 4As shown, at least a portion of the pusher 30 may be disposed in the second sub-accommodation space 112. As some embodiments of the present application, at least a portion of the pusher body 31 may be disposed in the second sub-accommodation space 112, the second mating member 32 may be disposed in the second sub-accommodation space 112, the mounting flange 13 may have an avoidance hole 132, and the avoidance hole 132 may be disposed along the thickness direction of the mounting flange 13 (i.e. Figure 4 The avoidance hole 132 is arranged to penetrate the mounting flange 13 (in the X direction shown), that is, the avoidance hole 132 can be constructed as a through hole.

[0052] The first matching member 22 can be inserted into the avoidance hole 132. Figure 4 As shown, the first mating component 22 can be inserted into the avoidance hole 132 and be transmission-connected with the second mating component 32 arranged in the second sub-accommodating space 112. Such a setting can avoid the first mating component 22 so that the first mating component 22 can be transmission-connected with the second mating component 32, and can make the arrangement of the driving component 20 and the pushing component 30 compact, which is beneficial to reducing the volume of the vehicle door driving mechanism 100 and reducing the difficulty of arranging the vehicle door driving mechanism 100.

[0053] In some embodiments of the present invention, Figure 2 , Figure 4 and Figure 6 As shown, the inner wall of the housing 10 may have a first guide portion 121 , and the outer wall of the pushing body 31 may have a second guide portion 312 , and the second guide portion 312 may be guided and matched with the first guide portion 121 .

[0054] As some embodiments of the present application, the first guide portion 121 can be configured as one of a guide protrusion and a guide groove, and the second guide portion 312 can be configured as the other of the guide protrusion and the guide groove. Figure 2 , Figure 4 and Figure 6 As shown, the inner side wall of the shell body 12 may have a guide groove, and the outer side wall of the push body 31 may have a guide protrusion, which may be arranged in the guide groove. When the push body 31 moves along the first direction (i.e. Figure 4 When the door driving mechanism 100 moves in the X direction (as shown in the figure), the guiding protrusion and the guiding groove cooperate to play a guiding role, so that the movement direction of the pushing body 31 can be accurate, and the probability of the pushing body 31 and the shell body 12 being stuck can be reduced, thereby improving the reliability of the door driving mechanism 100.

[0055] As some embodiments of the present application, the first guide portion 121 and the shell body 12 can be configured as separate parts, or the first guide portion 121 and the shell body 12 can be configured as an integral part, that is, the first guide portion 121 and the shell body 12 can be integrally formed. As some embodiments of the present application, the second guide portion 312 and the pushing body 31 can be configured as separate parts, or the second guide portion 312 and the pushing body 31 can be configured as an integral part, that is, the second guide portion 312 and the pushing body 31 can be integrally formed.

[0056] As some embodiments of this application, refer to Figure 2 , Figure 4 and Figure 6 As shown, the number of the first guide portions 121 can be set to be multiple, and the multiple first guide portions 121 can all be set on the inner side wall of the shell body 12, and the multiple first guide portions 121 can be sequentially spaced along the circumferential direction of the shell body 12. The number of the second guide portions 312 can be set to be multiple, and the multiple second guide portions 312 can all be set on the outer side wall of the pushing body 31, and the multiple second guide portions 312 can be sequentially spaced along the circumferential direction of the pushing body 31. The number of the first guide portions 121 is the same as the number of the second guide portions 312, and the multiple first guide portions 121 and the multiple second guide portions 312 are arranged one by one, so that the movement direction of the pushing body 31 can be more accurate, and the probability of the pushing body 31 and the shell body 12 being stuck can be further reduced.

[0057] As some embodiments of the present application, the housing 10 may further include a cover plate 16. Figure 1-Figure 5 As shown, the shell body 12 can define a first accommodating space 11, and both ends of the first accommodating space 11 can be open. Among the two open ends of the shell body 12, one open end is relatively close to the first sub-accommodating space 111, and the other open end is relatively far away from the first sub-accommodating space 111. The pushing body 31 can extend from the open end relatively far away from the first sub-accommodating space 111 and move toward the body of the vehicle (such as the side panel). The cover plate 16 can be arranged at the open end relatively close to the first sub-accommodating space 111 and block the open end. Such an arrangement can place the driving member 20 into the shell 10 through the open end relatively close to the first sub-accommodating space 111, which can reduce the assembly difficulty of the door drive mechanism 100 and improve the assembly efficiency of the door drive mechanism 100. Moreover, by making the cover plate 16 block the open end, it can prevent the driving member 20 from detaching from the shell 10 from the open end, and improve the reliability of the door drive mechanism 100.

[0058] As some embodiments of the present application, the cover plate 16 may be connected to the shell body 12 by means of, but not limited to, gluing or ultrasonic welding.

[0059] In some embodiments of the present invention, Figure 1-Figure 5 As shown, the outer wall of the housing 10 may have a first clamping portion 14 and a second clamping portion 15. Specifically, the outer wall of the shell body 12 may have a first clamping portion 14 and a second clamping portion 15. The first clamping portion 14 and the second clamping portion 15 may be arranged along a first direction (i.e., Figure 4 The housing 10 is arranged to be spaced apart from each other in the X direction as shown to define a snap-in space, and the housing 10 is suitable for being assembled with the vehicle door 40 through the snap-in space.

[0060] As some embodiments of this application, refer to Figure 1-Figure 5 As shown, the first clamping portion 14 can be constructed as a circular clamping flange, along the first direction (i.e. Figure 4 The first clamping portion 14 may be disposed at the end of the shell body 12. The second clamping portion 15 may be configured as a clamping protrusion, and the number of the second clamping portions 15 may be multiple, and the multiple second clamping portions 15 may be sequentially spaced along the circumferential direction of the shell body 12. The first clamping portion 14 and the second clamping portion 15 may define a clamping space, and a part of the structure of the door sheet metal 401 may be disposed in the clamping space, so that the door drive mechanism 100 may be clamped to the door 40, thereby facilitating the installation of the door drive mechanism 100 on the door 40.

[0061] As some embodiments of the present application, the door drive mechanism 100 proposed in the present application can be arranged at the position of the original buffer block of the door 40, so that it does not affect the aesthetic appearance of the vehicle and does not occupy the structural layout space of the door 40, thereby freeing up space for the layout of internal components of the door 40.

[0062] In some embodiments of the present invention, Figure 1-Figure 5 and Figure 7 As shown, the door driving mechanism 100 may further include a flexible member 33. The material of the flexible member 33 may be, but is not limited to, a rubber material. The flexible member 33 may be disposed at the end of the pushing body 31 away from the driving body 21, that is, the flexible member 33 may be disposed at the end of the pushing body 31 close to the vehicle body (e.g., the side panel). By providing the flexible member 33, when the pushing member 30 abuts against the vehicle body (e.g., the side panel) of the vehicle, the flexible member 33 may play a buffering role to reduce the probability of deformation and damage of the vehicle body (e.g., the side panel).

[0063] As some embodiments of the present application, the flexible member 33 can be integrally formed with the pushing body 31, that is, the flexible member 33 and the pushing body 31 can be an integral part. Such a setting can improve the connection strength between the flexible member 33 and the pushing body 31 and reduce the probability of separation of the flexible member 33 and the pushing body 31.

[0064] As some embodiments of the present application, Figure 1-Figure 5 As shown, the side wall of the shell body 12 may be provided with a harness hole, which may be arranged through the side wall of the shell body 12 along the thickness direction of the side wall of the shell body 12, or the cover plate 16 may be provided with a harness hole, which may be arranged through the cover plate 16 along the thickness direction of the cover plate 16, that is, the harness hole may be a through hole. The harness 41 of the drive body 21 may pass through the harness hole to be electrically connected to the controller of the vehicle.

[0065] According to the vehicle of the embodiment of the utility model, the door driving mechanism 100 for the vehicle of the above-mentioned embodiment is included. Through the door driving mechanism 100 of the present application, the driving member 20 can drive the pushing member 30 to move so that the pushing member 30 abuts against the body of the vehicle to open the door 40, thereby omitting the door handle structure on the outside of the door 40, which is beneficial to reducing the wind resistance of the vehicle during driving, reducing the energy consumption of the vehicle, improving the fuel economy of fuel vehicles, and improving the driving range of electric vehicles.
