Description

Technical Field

[0001] This application relates to the field of transmission mechanism technology, and in particular to a transmission device, drive device and vehicle. Background Technology

[0002] For vehicles with convertible tops, a movable convertible top is often installed on the vehicle body. To allow the convertible top to move relative to the vehicle body so that it can be stored in the space under the convertible top after it is opened, a multi-link mechanism is often used to guide the opening of the convertible top. In the multi-link mechanism, some links are used to guide the movement. Therefore, when realizing the complex movement of the convertible top, more links are needed to guide the movement, forming a complex linkage mechanism. This can lead to the convertible top getting stuck when any link does not operate smoothly during the movement. Summary of the Invention

Compared with the traditional multi-link mechanism, this application uses the limiting effect of the guide rail to confirm the motion path of the movable structure of the cockpit. Therefore, the use of the link used to limit the direction of movement can be reduced or even eliminated, thereby reducing the possibility of jamming during the use of the transmission device. This transmission method can determine the motion path of the transmission component by adjusting the adaptability of the guide rail, thus simplifying the structural design. At the same time, due to the reduction in the number of links and the reduction in the number of moving parts of the link members, the structural strength of the transmission device is improved.

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0058] In related technologies, when multi-link mechanisms are used for transmission, these mechanisms typically include a first link connecting the driver and the target object to transmit power, and a second link connected to the first link to restrict its direction of movement. The number of both the first and second links is often two or more, making the connections between the links complex. To enable the multi-link mechanism to move along a specific trajectory and drive the target object along a predetermined path, complex transmission routes often need to be designed. On the one hand, the links are prone to jamming during transmission; on the other hand, the large number of moving connection points between the links limits structural strength and affects the stability of the multi-link mechanism's transmission.

[0059] According to the first aspect of this application, referring to Figures 1 to 11 As shown, this application provides a transmission device 100 for a convertible cover of a vehicle, the transmission device 100 including: a transmission assembly 110 and a guide seat 120.

[0060] The transmission assembly 110 can be used to move at least a portion of the vehicle's cabin from a first position to a second position. As an example, the transmission assembly 110 can, for instance, form a transmission connection with the vehicle's convertible top 1a to move the convertible top 1a from the first position to the second position. Alternatively, the transmission assembly 110 can be connected between a drive unit 11 (such as an electric telescopic rod or linear motor) and the convertible top 1a to transmit power between the drive unit 11 and the convertible top 1a to move the convertible top 1a relative to the vehicle body 1b.

[0061] The guide seat 120 is movably connected to the transmission assembly 110 and is provided with a guide rail 121 that guides at least a portion of the transmission assembly 110 to move along a preset path, so that the convertible top 1a moves relative to the vehicle body 1b when the transmission assembly 110 moves along the preset path. At least a portion of the transmission assembly is engaged with the guide rail, so that the portion of the transmission assembly engaged with the guide rail moves along the preset path, causing the convertible top 1a to change position and orientation. The opening or closing of the convertible top 1a is achieved by changing its position and orientation, so that when the convertible top 1a is open, the convertible top can move to be housed within the space defined by the convertible top 1a and the vehicle body 1b, and when the convertible top 1a is closed, the space defined by the convertible top 1a and the vehicle body 1b can be sealed.

[0062] By adopting the above scheme, the transmission component 110 is guided to move along a predetermined route by setting a guide rail 121 on the guide seat 120. Compared with the traditional multi-link mechanism, this application uses the limiting function of the guide rail 121 to confirm the movement path of the movable structure of the cockpit. Therefore, the use of the link used to limit the direction of movement can be reduced or even eliminated, thereby reducing the possibility of jamming during the use of the transmission device 100. This transmission method can determine the movement path of the transmission component 110 by adjusting the adaptability of the guide rail 121, thus simplifying the structural design. At the same time, due to the reduction in the number of links and the reduction in the number of moving parts of the link members, the structural strength of the transmission device 100 is improved.

[0063] It should be noted that although this application uses the transmission device 100 acting on the convertible cover 1a of the vehicle to drive the convertible cover 1a to move relative to the vehicle body 1b as an example, the transmission device 100 can not only act on the convertible cover 1a, but can also be flexibly configured on other movable structures in the cabin, or on different equipment such as machine tools and general machinery, according to actual needs. This application does not impose any restrictions here.

[0064] Based on the guiding effect of the guide rail 121 on the movement of the transmission component 110, the transmission component 110 can achieve different types of movement relative to the guide seat 120, for example, referring to... Figure 2 and Figure 4 As shown, the preset path includes a straight path, so that the transmission assembly 110 is in a sliding connection with the guide seat 120 at least, that is, the transmission assembly drives the convertible cover 1a of the vehicle to slide relative to the guide seat 120.

[0065] In the specific design, this movement method allows the convertible cover 1a to be guided, for example, to tilt upwards and move away from the vehicle body 1b by sliding the transmission component 110 when it is opened, so as to avoid the convertible cover 1a hitting the vehicle body 1b during the opening process.

[0066] For example, refer to Figure 5 and Figure 6 As shown, the preset path includes an arc-shaped path, so that the transmission assembly 110 is rotatably connected at least relative to the guide seat 120. This means that the transmission assembly drives the vehicle's convertible top 1a to rotate relative to the guide seat.

[0067] In the specific design, this movement allows the convertible top 1a to rotate relative to the vehicle body 1b. This allows the convertible top 1a to create space within the area defined by the convertible top 1a and the vehicle body, enabling the convertible top to move and be stored within it.

[0068] The guide rail 121 can take various forms. As a specific example, the guide rail 121 can be a protrusion on the guide seat 120, with a corresponding groove formed on the transmission assembly 110. The protrusion is inserted into the groove and moves within the groove to guide the movement direction of the transmission assembly 110. This exemplary embodiment is not shown in the accompanying drawings.

[0069] As another concrete example, refer to Figure 4 As shown, the guide seat 120 is provided with a guide groove 122, and the guide track 121 includes the groove wall formed on the guide seat 120 by the guide groove 122. Correspondingly, at least a portion of the transmission assembly 110 is inserted into the guide groove 122, so that the transmission assembly 110 moves under the guidance of the groove wall formed on the guide seat 120 by the guide groove 122. This method can reduce the number of slots configured on the transmission assembly 110 to ensure the structural strength of the transmission assembly 110. The main function of the guide seat 120 is to guide the direction of movement, and it is not a structure that mainly bears the load during the transmission process. Therefore, the influence of setting the guide groove 122 on the guide seat 120 on the structural strength of the transmission device 100 is relatively small, so that this configuration can ensure the overall structural strength of the transmission device 100.

[0070] In some embodiments, refer to Figure 8 As shown, the wall of the guide seat 120 forming the guide groove 122 includes a straight guide surface 123 extending along a straight line. During the movement of the transmission component 110 along the preset path, it can contact the straight guide surface 123 to guide the transmission component 110 to slide relative to the guide seat 120, thereby enabling the transmission component 110 to slide at least a certain distance relative to the guide seat 120 during the movement of the transmission component 110 along the preset path.

[0071] In some embodiments, refer to Figure 5 As shown, the wall surface of the guide seat 120 forming the guide groove 122 includes an arc-shaped guide surface 124 extending along an arc. During the movement of the transmission component 110 along the preset path, it can contact the arc-shaped guide surface 124 to guide the transmission component 110 to rotate relative to the guide seat 120. This ensures that the transmission component 110 can rotate at least a certain angle relative to the guide seat 120 during the movement along the preset path.

[0072] In some embodiments, at least one curved guide surface 124 and at least one straight guide surface 123 are intersecting. That is, during the movement of the transmission assembly 110 along a preset path, it can move from a state guided by the curved guide surface 124 to a state guided by the straight guide surface 123; or from a state guided by the straight guide surface 123 to a state guided by the curved guide surface 124.

[0073] Accordingly, the transmission component 110 can move linearly or rotate relative to the guide seat 120 during its operation, thereby achieving a more complex motion mode, so that the transmission component 110 can complete a complex preset path, and then drive the convertible cover 1a to complete a complex motion route according to actual needs, so as to complete the opening or closing action of the convertible cover 1a and avoid collision with the body 1b.

[0074] In some embodiments, during the movement of the transmission assembly 110, at least a portion of the transmission assembly 110, after contacting the linear guide surface 123, moves to contact the curved guide surface 124, thereby guiding the transmission assembly 110 to slide relative to the guide seat 120 and then rotate relative to the guide seat 120. Considering some practical application scenarios, such as a vehicle's rear window 1c potentially being able to move up and down relative to the vehicle body 1b to adjust the position of the rear window 1c to provide different driving experiences when the convertible cover 1a is open or closed, to avoid interference between the movement of the convertible cover 1a and the movement of the rear window 1c, the aforementioned method of guiding the transmission assembly 110 to slide relative to the guide seat 120 and then rotate relative to the guide seat 120 can avoid the rear window 1c when the convertible cover 1a is open, thus allowing the rear window 1c and the convertible cover 1a to be adjusted independently.

[0075] In some embodiments, refer to Figure 2 As shown, the transmission assembly 110 includes a first type of transmission member 111 and a second type of transmission member 112. The first type of transmission member 111 has a first end A1 and a second end A2. The first end A1 is movably connected to the guide seat 120, and the second end A2 is connected to the convertible top 1a of the vehicle to move the convertible top 1a when in motion. The second type of transmission member 112 has a third end A3 and a fourth end A4. The third end A3 of the second type of transmission member 112 is connected to the first type of transmission member 111, and the fourth end A4 is adapted to be connected to the driver to transmit the force that causes the first type of transmission member 111 to move. That is, the transmission assembly 110 can use at least two transmission members connected to transmit power, realizing the transmission of power from the driver 11 to the convertible top 1a of the vehicle. This reduces the load on a single transmission member, thereby ensuring structural strength.

[0076] However, too many transmission components can also lead to too many movable connections between the transmission components, affecting the structural strength. Therefore, in some embodiments, the number of transmission components for transmitting power between the driver 11 and the convertible cover 1a is between two and four, in order to ensure the structural strength of the transmission assembly 110.

[0077] In some embodiments, the number of transmission components for transmitting power between the driver 11 and the convertible cover 1a can also be one. For example, one end of the transmission component is connected to the driver 11 and the other end is connected to the convertible cover 1a, which can also realize the transmission of power from the driver 11 to the convertible cover 1a.

[0078] In some embodiments, refer to Figure 2 As shown, the guide rail 121, adapted to the first type of transmission member 111 mentioned above, includes a first guide segment 121a. The first guide segment 121a is connected to the first type of transmission member 111 to guide its movement. This restricts the movement path of the convertible cover 1a by guiding the movement of the first type of transmission member 111.

[0079] In some embodiments, the guide rail 121, adapted to the second type of transmission member 112 mentioned above, further includes a second guide segment 121b. The second guide segment 121b connects with the second type of transmission member 112 to guide its movement. Specifically, when the second type of transmission member 112 moves relative to the guide seat 120 under the guidance of the second guide segment 121b, it drives the first type of transmission member 111 to move relative to the guide seat 120 under the guidance of the first guide segment 121a. This cooperation allows the guide seat 120 to restrict the movement directions of the first type of transmission member 111 and the second type of transmission member 112 respectively during the movement of the transmission assembly 110, resulting in more connection points between the transmission assembly 110 and the guide seat 120, and a more stable structure for the transmission device 100.

[0080] Furthermore, compared to the method where the driver 11 is directly connected to the first type of transmission member 111 so that the first type of transmission member 111 directly transmits the power provided by the driver 11 to the convertible cover 1a, by setting the second type of transmission member 112, the driver 11 can be connected to the second type of transmission member 112. By guiding the movement path of the second type of transmission member 112, the speed change of the first type of transmission member 111 during the movement process can be stabilized, which can reduce the possibility of sudden changes in the movement speed of the first type of transmission member 111, thereby improving the transmission stability.

[0081] In the specific plan, refer to Figure 3 As shown, the third end A3 of the second type of transmission member 112 is rotatably connected to the first type of transmission member 111 about the first rotation axis L1. The fourth end A4 of the second type of transmission member 112 is adapted to be rotatably connected to the driver 11 about the second rotation axis L2. In a more specific embodiment, the third end A3 of the second type of transmission member 112 is hinged to the first end A1 of the first type of transmission member 111, and the fourth end A4 of the second type of transmission member 112 is hinged to the driver 11, which is, for example, an electric telescopic rod, a linear motor, etc.

[0082] In some embodiments, the first rotation axis L1 and the second rotation axis L2 are arranged in parallel. This arrangement allows at least some of the degrees of freedom of movement in the transmission assembly 110 to be in the same plane or in mutually parallel planes, which can reduce the space occupied by the transmission assembly 110 during movement. This configuration can facilitate the integration of the transmission device 100 in use scenarios with limited space, such as vehicles.

[0083] As a specific plan, refer to Figure 3 and Figure 9 As shown, the first type of transmission component 111 includes a first body 111a connected to the second type of transmission component 112, and a first column 111b disposed on the first body 111a. The first guide section 121a is configured as a first guide groove 122a that cooperates with the first column 111b.

[0084] A first column 111b is disposed at the first end A1 of the first type of transmission member 111. The first column 111b is at least partially inserted into the first guide groove 122a and forms wall contact with the guide seat 120 of the first guide groove 122a. The first guide groove 122a is used to restrict the movement direction of the first column 111b, thereby guiding the movement direction of the first type of transmission member 111. A first blocking member 111c can be fixedly disposed on the first column 111b. The first blocking member 111c and the first body 111a are located outside the first guide groove 122a and are respectively located on opposite sides of the guide seat 120. That is, at least a part of the guide seat 120 is clamped between the first blocking member 111c and the first body 111a, so that the first column 111b can be stably present in the first guide groove 122a, making the movement of the first type of transmission member 111 stable. In a more specific embodiment, the first blocking member 111c and the first column 111b can be integrally formed, for example, the whole formed by the two is a bolt that is threadedly connected to the first body 111a.

[0085] Accordingly, as a specific plan, refer to Figure 3 and Figure 10 As shown, the second type of transmission member 112 includes a second body 112a connected to the first type of transmission member 111, and a second column 112b disposed on the second body 112a. The second guide section 121b is configured as a second guide groove 122b that mates with the second column 112b. The second column 112b is at least partially inserted into the second guide groove 122b and forms wall contact with the guide seat 120 of the second guide groove 122b, thereby using the second guide groove 122b to restrict the movement direction of the second column 112b, thereby guiding the movement direction of the second type of transmission member 112.

[0086] A second blocking member 112c can be fixedly disposed on the second column 112b. The second blocking member 112c is located outside the second guide groove 122b and on opposite sides of the guide seat 120, respectively. That is, at least a portion of the guide seat 120 is clamped between the second blocking member 112c and the second body 112a, so that the second column 112b can be stably present in the second guide groove 122b, thereby stabilizing the movement of the second type of transmission member 112. In a more specific embodiment, the second blocking member 112c and the second column 112b can be integrally formed, for example, the whole formed by the two can be a bolt threadedly connected to the second body 112a.

[0087] In the specific plan, refer to Figure 3 , Figure 9 and Figure 10 A pin 114 is inserted between the first end A1 of the first body 111a and the third end A3 of the second body 112a, so that the first body 111a and the second body 112a are hinged together by the pin 114. More specifically, the pin 114 includes a pin body 114a located at least partially in the guide groove 122 and a blocking portion 114b formed at one end of the pin body 114a, wherein the first body 111a and the second body 112a are located on the same side of the guide seat, while the blocking portion 114b is located on the other side of the guide seat, so that the whole consisting of the first body 111a and the second body 112a and the blocking portion 114b together form a clamping of the guide seat to reduce the swaying of the first body 111a and the second body 112a in space.

[0088] Understandably, referring to Figure 7 and Figure 8 As shown, the first guide groove 122a and the second guide groove 122b are at least a portion of the guide through groove 122 mentioned above. In this case, the straight guide surface 123 mentioned above may include a first straight guide surface 123a for forming at least a portion of the first guide groove 122a, and a second straight guide surface 123b for forming at least a portion of the second guide groove 122b. Correspondingly, the curved guide surface 124 mentioned above may include a first curved guide surface 124a for forming at least a portion of the first guide groove 122a, and a second curved guide surface 124b for forming at least a portion of the second guide groove 122b.

[0089] The first guide slot 122a and the second guide slot 122b can be connected. Of course, depending on the actual situation, they can also be configured to be isolated from each other.

[0090] In some embodiments, the first type of transmission member 111, guided by the first guide segment 121a, can slide relative to the guide seat 120 along the first direction X1, and / or the first type of transmission member 111, guided by the first guide segment 121a, can rotate relative to the guide seat 120 about the third rotation axis L3. Considering further ensuring smooth movement of the transmission assembly 110 and reducing the possibility of movement jamming, refer to... Figure 2 and Figure 4 As shown, during the sliding process of the first type of transmission member 111 relative to the guide seat 120 along the first direction X1, the angle α between the common perpendicular of the first rotation axis L1 and the second rotation axis L2 and the first direction X1 ranges from 120° ≤ α < 180°. When the first type of transmission member 111, guided by the first guide section 121a, can slide a certain distance relative to the guide seat 120 along the first direction X1, and can rotate a certain angle around the third rotation axis L3 during the movement, the above configuration enables the first type of transmission member 111 to smoothly adjust from sliding relative to the guide seat 120 to rotating relative to the guide seat 120, while allowing the power provided by the driver 11 to be transmitted to the first type of transmission member 111 to a greater extent through the second type of transmission member 112, thereby ensuring transmission efficiency.

[0091] In some embodiments, the transmission assembly 110 further includes a connector 113. The connector 113 is disposed between the first type of transmission member 111 and the convertible top 1a of the vehicle to connect the first type of transmission member 111 and the convertible top 1a. Specifically, the connector is, for example, connected between the second end A2 of the first type of transmission member 111 and the convertible top 1a. The connector 113 is integrally formed with the first type of transmission member 111 or forms a fixed connection. The force transmission from the first type of transmission member 111 to the convertible top 1a is achieved by providing the connector 113. The specific dimensions of the connector 113 can be configured according to the vehicle, so that when the first type of transmission member 111 moves, the convertible top 1a can move a larger or smaller range of motion according to the dimensions of the connector 113, making the transmission device 100 more suitable for integration into the corresponding vehicle.

[0092] In some embodiments, the connector 113 and the second type of transmission member 112 are respectively disposed at opposite ends of the first type of transmission member 111. This is to keep the connector 113 relatively away from the second type of transmission member 112, facilitating their installation on the first type of transmission member 111.
