[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0029] The following is for reference. Figures 1-3 A front cover drive assembly according to a first aspect embodiment of the present invention is described.
[0030] like Figures 1-3 As shown, the front cover drive assembly according to the first aspect of the present invention includes: a drive member 10, a drive shaft 20, a drive arm 30, and a front cover hinge 40.
[0031] Specifically, the drive member 10 and the drive shaft 20 are connected by transmission. The drive shaft 20 is provided with a drive gear 21, and the drive arm 30 is provided with a connecting part 31. One end of the drive arm 30 in a first direction is provided with a toothed section 32. The first direction is perpendicular to the axial direction of the drive gear 21. The toothed section 32 and the connecting part 31 are arranged at intervals in the first direction. The toothed section 32 meshes with the drive gear 21. The front cover hinge 40 is used to connect with the front cover. The front cover hinge 40 and the connecting part 31 are rotatably connected. The drive gear 21 is adapted to drive the drive arm 30 to swing, so as to drive the front cover hinge 40 to open and close the front cover.
[0032] When a user needs to open or close the front cover of a vehicle while using it, the drive unit 10 drives the drive gear 21 to rotate. The drive gear 21 then pushes the toothed segment 32 to move. It is understood that as the toothed segment 32 engages with the drive gear 21 at different positions, the relative angle between the axis of the drive arm 30 and the axis of the drive gear 21 changes under the constraint of the front cover hinge 40 on the connecting part 31. Thus, the drive gear 21 can drive the drive arm 30 to swing through the toothed segment 32. During the swinging process of the drive arm 30, the drive arm 30 pushes the front cover hinge 40 to move along a set stroke. During the movement of the front cover hinge 40, the front cover hinge 40 drives the front cover to move, thereby realizing the opening and closing of the front cover.
[0033] In this assembly, the drive gear 21 drives the front cover hinge 40 via the drive arm 30, which has toothed segments 32. The front cover drive assembly has a small number of components and a relatively simple structure. The process of machining the toothed segments 32 on the drive arm 30 is relatively simple, and it is easy to produce the toothed segments 32 on the drive arm 30 during production. During the operation of the front cover drive assembly, the teeth of the drive gear 21 and the teeth of the toothed segments 32 are unlikely to slip, resulting in high reliability of the meshing transmission between the drive gear 21 and the toothed segments 32.
[0034] According to the front cover drive assembly of the first aspect of the present invention, by providing a toothed segment 32 on the drive arm 30, the drive gear 21 drives the drive arm 30 to swing through the toothed segment 32, thereby driving the front cover hinge 40. On the one hand, the structure of the front cover drive assembly is relatively simple, and the process of machining the toothed segment 32 on the drive arm 30 is also relatively simple, which can reduce the production difficulty and production cost of the front cover drive assembly. On the other hand, the meshing transmission reliability of the drive gear 21 and the toothed segment 32 is high, which can improve the reliability of the front cover drive assembly during operation.
[0035] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the tooth segment 32 extends along an arc line toward the opening of the connecting portion 31. Therefore, the angle between the line connecting the connecting portion 31 and the center of the drive gear 21 and the radial extension direction of the tooth segment 32 is small. During the operation of the front cover drive assembly, the displacement of the drive arm 30 along the path of the drive gear 21 is small. On the one hand, the trajectory of the drive arm 30 is easier to confirm during product design, reducing the design difficulty of the front cover drive assembly. On the other hand, slippage between the drive gear 21 and the tooth segment 32 is less likely, further improving the reliability of the front cover drive assembly during operation.
[0036] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, in the direction of the tooth segment 32 toward the connecting part 31, the size of the part of the drive arm 30 decreases in the second direction, and the first direction, the second direction and the axis direction of the drive shaft 20 are perpendicular to each other.
[0037] It is understandable that during the swing of the drive arm 30 relative to the axis of the drive gear 21, in order to improve the reliability of the meshing between the tooth segment 32 and the drive gear 21, and to make the stroke of the drive arm 30 meet the stroke requirements of the front cover hinge 40, the tooth segment 32 needs to be longer than a set length. On the main body of the drive arm 30, by making some parts smaller, the material used to produce the drive arm 30 can be saved, thereby further reducing the production cost.
[0038] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, in the direction from the tooth segment 32 toward the connecting portion 31, the dimension of the drive arm 30 first decreases and then increases in the second direction.
[0039] It is understandable that the larger the size of the solid structure at the connecting part 31, the higher the connection strength between the connecting part 31 and the front cover hinge 40. By first decreasing and then increasing the size of the drive arm 30 in the second direction, the solid size at the connecting part 31 can be increased, thereby increasing the connection strength between the connecting part 31 and the front cover hinge 40.
[0040] In some embodiments of this utility model, such as Figure 1 As shown, the drive arm 30 includes a main body section 33 and an extension section 34. The projection of the main body section 33 in the projection plane perpendicular to the axis of the drive gear 21 is a fan-shaped ring. The tooth section 32 is formed on the protruding side of the main body section 33. The extension section 34 is connected to the concave side of the main body section 33. The connecting part 31 is provided on the extension section 34.
[0041] In this way, the size of the main body section 33 is reduced in the direction of the toothed section 32 toward the connecting part 31, which can reduce the size of the drive arm 30 in the second direction and make the torque change on the drive arm 30 more uniform, thereby improving the stability of the drive arm 30 during the swinging process. In the product design process, the size of the extension section 34 and the main body section 33 can be adjusted so that the drive arm 30 meets the requirements of the connection strength with the front cover hinge 40 and the requirements of the travel of the front cover hinge 40.
[0042] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, in the direction of the toothed segment 32 toward the connecting portion 31, the edge of the extension segment 34 in the second direction is connected to the main body segment 33 by an inwardly recessed arc segment.
[0043] Therefore, in the direction from the tooth segment 32 toward the connecting part 31, the size of the drive arm 30 in the second direction can be reduced first and then increased, and the uniformity of torque change on the drive arm 30 can be further improved, thereby further improving the stability of the drive arm 30 during the swinging process.
[0044] In some embodiments of this utility model, the drive arm 30 is plate-shaped. Therefore, the drive arm 30 occupies less space, facilitating its placement on the vehicle.
[0045] In some embodiments of this utility model, such as Figures 1-3 As shown, the drive shaft 20 extends in the left-right direction of the vehicle, and the drive member 10 has an output shaft (not shown in the figure) that extends in the front-rear direction of the vehicle and is connected to the drive shaft 20 in a transmission manner.
[0046] Preferably, the drive shaft 20 and the output shaft are connected by a bevel gear transmission, and the drive component 10 is a drive motor.
[0047] It is understandable that the dimension of the drive component 10 in the direction of the output shaft axis is larger than the dimension of the drive component 10 in the direction of width. The output shaft of the drive component 10 extends along the front-rear direction of the vehicle. In the left-right direction of the vehicle, the dimension of the drive component 10 extending into the front engine compartment is smaller. This can reduce the difficulty of arranging the components in the front engine compartment.
[0048] In some embodiments of this utility model, such as Figures 1-3 As shown, the front cover hinge 40 includes: a movable arm 41, a first support arm 42, and a second support arm 43.
[0049] Specifically, the movable arm 41 is used to connect to the front cover. The movable arm 41 is provided with a first mounting part and a second mounting part. The first mounting part and the second mounting part are arranged at intervals along the length of the movable arm 41. One end of the first support arm 42 is rotatably connected to the connecting part 31, and the other end of the first support arm 42 is rotatably connected to the first mounting part. One end of the second support arm 43 is rotatably connected to the vehicle body 100, and the other end of the second support arm 43 is rotatably connected to the second mounting part.
[0050] When the user needs to open the front cover, the drive component 10 drives the drive gear 21 to rotate. The drive gear 21 pushes the tooth segment 32 to move, causing the drive arm 30 to swing. The drive arm 30 pushes the movable arm 41 upward through the first support arm 42 until the set front cover opening position is reached. At the same time, the second support arm 43 swings relative to the vehicle body 100 to cooperate with the drive arm 30 and the first support arm 42 to limit the upward movement trajectory of the movable arm 41.
[0051] When the user needs to close the front cover, the drive unit 10 drives the drive gear 21 to rotate in the opposite direction of the aforementioned rotation direction. The drive gear 21 pushes the tooth segment 32 to move in the opposite direction of the aforementioned movement direction, causing the drive arm 30 to swing in the opposite direction of the aforementioned swing direction. The drive arm 30 drives the movable arm 41 downward through the first support arm 42 until the set front cover closing position is reached. At the same time, the second support arm 43 swings relative to the vehicle body 100 to cooperate with the drive arm 30 and the first support arm 42 to limit the upward movement trajectory of the movable arm 41.
[0052] Therefore, the drive component 10 can drive the opening and closing of the front cover, and the transmission structure between the front cover hinge 40 and the drive arm 30 is a multi-link type. On the one hand, it can further simplify the structure of the front cover drive assembly, and on the other hand, it can reduce the space occupied by the front cover drive assembly, thereby reducing the design difficulty of the front cover drive assembly.
[0053] Preferably, the connecting part 31 includes a connecting hole, the first support arm 42 is provided with a first rotating hole and a second rotating hole, the first axle pin 50 passes through the connecting hole and the first rotating hole to realize the rotatable connection between the connecting part 31 and the first support arm 42, the first mounting part includes a third rotating hole, the second axle pin 51 passes through the second rotating hole and the third rotating hole to realize the rotatable connection between the first support arm 42 and the first mounting part, the body 100 is provided with a fourth rotating hole, the second support arm 43 is provided with a fifth rotating hole and a sixth rotating hole, the third axle pin 52 passes through the fourth rotating hole and the fifth rotating hole to realize the rotatable connection between the second support arm 43 and the body 100, the second mounting part includes a seventh rotating hole, the fourth axle pin 53 passes through the sixth rotating hole and the seventh rotating hole to realize the rotatable connection between the second support arm 43 and the second mounting part.
[0054] A vehicle according to a second aspect of the present invention includes: a body 100, a front hood, and the aforementioned front hood drive assembly according to a first aspect of the present invention.
[0055] Specifically, the front cover is adapted to cover the front engine compartment of the vehicle body 100, the drive unit 10 and the drive shaft 20 are provided on the vehicle body 100, the front cover hinge 40 is connected to the front cover, and the front cover hinge 40 is rotatably connected to the vehicle body 100.
[0056] When a user needs to open or close the front cover of the vehicle while using it, the drive unit 10 drives the drive gear 21 to rotate. The drive gear 21 pushes the tooth segment 32 to move, thereby causing the drive arm 30 to swing. During the swinging process of the drive arm 30, the drive arm 30 pushes the front cover hinge 40 to move along a set stroke. At the same time, the front cover hinge 40 rotates relative to the vehicle body 100 to limit the trajectory of the front cover hinge 40. During the movement of the front cover hinge 40, the front cover hinge 40 drives the front cover to move, thereby realizing the opening and closing of the front cover.
[0057] The vehicle according to the second aspect embodiment of the present invention, by providing the front cover drive assembly according to the first aspect embodiment of the present invention, can reduce the production cost of the vehicle and improve the reliability of the vehicle during operation.
