[0057] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0058] When a multi-link mechanism is used for transmission in the related art, the multi-link mechanism often includes a first type of link connected between the driver and the target object for transmitting power; and a second type of link connected to the first type of link to limit the moving direction of the first type of link when the first type of link moves. Among them, the number of the first type of link and the second type of link is often two or more, which makes the connection position between the various links of the multi-link mechanism complicated. In order to make the multi-link mechanism move along a specific motion trajectory to drive the target object to move along a predetermined route, it is often necessary to design a complex transmission route. On the one hand, when the multi-link mechanism is transmitting, each link is prone to jamming when moving. On the other hand, there are many active connection parts between the links, which limits the structural strength and affects the stability of the multi-link mechanism transmission.

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

[0060] The transmission assembly 110 can be used to drive at least a portion of the vehicle's cabin to move from a first position to a second position. As an example of a specific solution, the transmission assembly 110 can be used to form a transmission connection with the vehicle's convertible cover 1a to drive the convertible cover 1a to move from the first position to the second position. As a specific solution, the transmission assembly 110 can be connected between a driver 11 such as an electric telescopic rod, a linear motor, etc. and the convertible cover 1a to transmit power between the driver 11 and the convertible cover 1a to move the convertible cover 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 track 121 for guiding at least a portion of the transmission assembly 110 to move along a preset path, so that the convertible cover 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 coupled to the guide track, so that the portion of the transmission assembly coupled to the guide track drives the convertible cover 1a of the vehicle to change its position and posture when moving along the preset path. The convertible cover 1a is opened or closed by changing its position and posture, so that when the convertible cover 1a is opened, the convertible can be moved to be stored in the space defined by the convertible cover 1a and the vehicle body 1b, and when the convertible cover 1a is closed, the space defined by the convertible cover 1a and the vehicle body 1b can be closed.

[0062] By adopting the above scheme, a guide track 121 is set on the guide seat 120 to guide the transmission component 110 to move along a predetermined route. Compared with the traditional multi-link mechanism, the present application utilizes the limiting effect of the guide track 121 to realize the confirmation of the movement path of the movable structure of the cockpit, thereby reducing or even eliminating the use of the connecting rod for limiting the movement direction, thereby reducing the possibility of jamming during the use of the transmission device 100. This transmission method can determine the movement route of the transmission component 110 through the adaptability adjustment of the guide track 121, thereby simplifying the structural design. At the same time, due to the reduction in the number of connecting rods and the reduction in the number of movable parts of the connecting rods, the structural strength of the transmission device 100 is improved.

[0063] It should be noted that although the present application uses the example of 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, 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 according to actual needs, or on different equipment such as machine tools, general machinery, etc. for transmission, and the present application does not limit this.

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

[0065] In a specific solution, this movement mode allows the convertible cover 1a to be guided to move, for example, tilted upward and away from the vehicle body 1b through the sliding of the transmission assembly 110 when the convertible cover 1a is opened, so as to avoid the convertible cover 1a from 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 path, so that the transmission assembly 110 is at least rotatably connected relative to the guide seat 120. That is, the transmission assembly drives the convertible cover 1a of the vehicle to rotate relative to the guide seat.

[0067] In a specific embodiment, this movement mode can enable the convertible cover 1a to rotate relative to the vehicle body 1b, so that the convertible cover 1a can avoid the space that allows the convertible to move and be stored in the space defined by the convertible cover 1a and the vehicle body.

[0068] There are many ways to implement the specific form of the guide rail 121. As a specific example, the guide rail 121 can be a protrusion provided on the guide seat 120, and a corresponding slot is formed on the transmission assembly 110, and the protrusion is inserted into the slot and moves in the slot to guide the movement direction of the transmission assembly 110. This exemplary embodiment is not shown in the drawings.

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

[0070] In some embodiments, reference Figure 8 As shown, the wall surface of the guide slot 122 formed by the guide seat 120 includes a straight guide surface 123 extending in a straight line. The transmission component 110 can contact the straight guide surface 123 during the movement along the preset path to guide the transmission component 110 to slide relative to the guide seat 120, thereby achieving that the transmission component 110 can at least slide a certain distance relative to the guide seat 120 during the movement along the preset path.

[0071] In some embodiments, reference Figure 5 As shown, the wall surface of the guide seat 120 forming the guide slot 122 includes an arc guide surface 124 extending along an arc, and the transmission assembly 110 can contact the arc guide surface 124 during the movement along the preset path to guide the transmission assembly 110 to rotate relative to the guide seat 120. In this way, the transmission assembly 110 can at least rotate a certain angle relative to the guide seat 120 during the movement along the preset path.

[0072] In some embodiments, at least one arc guide surface 124 and at least one linear guide surface 123 are arranged to intersect. That is, during the movement of the transmission assembly 110 along the preset path, the transmission assembly 110 can move from the state of moving under the guidance of the arc guide surface 124 to the state of moving under the guidance of the linear guide surface 123; or from the state of moving under the guidance of the linear guide surface 123 to the state of moving under the guidance of the arc guide surface 124.

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

[0074] In some embodiments, during the movement of the transmission assembly 110, at least a portion of the transmission assembly 110 contacts the linear guide surface 123 and then moves to contact the arc guide surface 124, so as to guide 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, for example, the rear window 1c of the vehicle may be able to move up and down relative to the vehicle body 1b, so as to adjust the position of the rear window 1c when the convertible cover 1a of the vehicle is opened or closed to provide different driving experiences. In order to avoid the interference between the movement of the convertible cover 1a and the movement of the rear window 1c, the above-mentioned 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 opened, so that the rear window 1c and the convertible cover 1a can be adjusted independently of each other.

[0075] In some embodiments, reference Figure 2 As shown, the transmission assembly 110 includes: a first type transmission member 111 and a second type transmission member 112. The first type transmission member 111 has a first end A1 and a second end A2, wherein the first end A1 of the first type transmission member is movably connected to the guide seat 120, and the second end A2 is connected to the convertible cover 1a of the vehicle to drive the convertible cover 1a of the vehicle to move when moving; the second type transmission member 112 has a third end A3 and a fourth end A4, wherein the third end A3 of the second type transmission member 112 is connected to the first type transmission member 111, and the fourth end A4 is suitable for connecting to the driver to transmit the force that causes the first type transmission member 111 to move to the first type transmission member 111. That is, the transmission assembly 110 can adopt a connection method of at least two transmission members for transmitting power to realize the transmission of power from the driver 11 to the convertible cover 1a of the vehicle, which can reduce the load on a single transmission member, thereby ensuring the structural strength.

[0076] However, too many transmission parts will also lead to too many active connection positions between the transmission parts, affecting the structural strength. Therefore, in some embodiments, the number of transmission parts for transmitting power between the driver 11 and the convertible cover 1a is between two and four 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, reference Figure 2 As shown, the guide track 121 is adaptively configured with the first type transmission member 111 mentioned above, and includes: a first guide section 121a. The first guide section 121a is connected to the first type transmission member 111 to guide the movement of the first type transmission member 111. By guiding the movement of the first type transmission member 111, the movement path of the convertible cover 1a is restricted.

[0079] In some embodiments, the guide rail 121 is adaptively configured with the second type of transmission member 112 mentioned above, and further includes: a second guide section 121b. The second guide section 121b is connected to the second type of transmission member 112 to guide the movement of the second type of transmission member 112. In a specific solution, when the second type of transmission member 112 moves relative to the guide seat 120 under the guidance of the second guide section 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 section 121a. In this cooperation mode, during the movement of the transmission assembly 110, the guide seat 120 can respectively limit the movement directions of the first type of transmission member 111 and the second type of transmission member 112, so that there are more connection parts between the transmission assembly 110 and the guide seat 120, and the structure of the transmission device 100 is more stable.

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

[0081] For specific plans, refer to Figure 3 As shown, the third end A3 of the second type transmission member 112 is rotatably connected with the first type transmission member 111 around the first rotation axis L1. The fourth end A4 of the second type transmission member 112 is suitable for being rotatably connected with the driver 11 around the second rotation axis L2. In a more specific solution, the third end A3 of the second type transmission member 112 is hinged to the first end A1 of the first type transmission member 111, and the fourth end A4 of the second type transmission member 112 is hinged to the driver 11, and the driver 11 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 part of the freedom of movement of the transmission component 110 to be in the same plane, or in planes parallel to each other, which can reduce the space occupied by the transmission component 110 during movement. This configuration can facilitate the integration of the transmission device 100 in scenarios with limited space such as vehicles.

[0083] As a specific plan, refer to Figure 3 and Fig. 9 As shown, the first type transmission member 111 includes a first body 111a connected to the second type transmission member 112, and a first column 111b provided on the first body 111a, and the first guide section 121a is configured as a first guide groove 122a matched with the first column 111b.

[0084] The first column 111b is disposed at the first end A1 of the first type transmission member 111. The first column 111b is at least partially inserted into the first guide groove 122a and contacts the wall of the first guide groove 122a formed by the guide seat 120, so that the first guide groove 122a is used to limit the moving direction of the first column 111b, thereby achieving the guidance of the moving direction of the first type transmission member 111. The 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 two 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, so that the first type transmission member 111 moves stably. In a more specific solution, the first blocking member 111c and the first column 111b may be formed as one piece, for example, the whole formed by the two is a bolt threadedly connected to the first body 111a.

[0085] Accordingly, as a specific plan, refer to Figure 3 and Fig.10 As shown, the second type transmission member 112 includes a second body 112a connected to the first type transmission member 111, and a second column 112b provided on the second body 112a, and the second guide section 121b is configured as a second guide groove 122b matched with the second column 112b. The second column 112b is at least partially inserted into the second guide groove 122b, and contacts with the wall surface of the second guide groove 122b formed by the guide seat 120, so that the second guide groove 122b is used to limit the moving direction of the second column 112b, thereby achieving the guidance of the moving direction of the second type transmission member 112.

[0086] The second blocking member 112c can be fixedly arranged on the second column 112b, and the second blocking member 112c and the second body 112a are located outside the second guide groove 122b, and are respectively located on two opposite sides of the guide seat 120, that is, at least a part 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, so that the second type transmission member 112 can move stably. In a more specific solution, the second blocking member 112c and the second column 112b can be formed as one piece, for example, the whole formed by the two is a bolt threadedly connected to the second body 112a.

[0087] For specific plans, refer to Figure 3 , Fig. 9 and Fig.10 A pin shaft 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 hingedly connected through the pin shaft 114. More specifically, the pin shaft 114 includes a pin column body 114a at least partially located in the guide groove 122 and a blocking portion 114b formed at one end of the pin column body 114a, wherein the first body 111a and the second body 112a are located on the same side of the guide seat, and the blocking portion 114b is located on the other side of the guide seat, so that the whole formed by the first body 111a and the second body 112a and the blocking portion 114b together clamp the guide seat, so as to reduce the shaking of the first body 111a and the second body 112a in space.

[0088] It is understandable that, referring to Figure 7 and Figure 8 As shown, the first guide groove 122a and the second guide groove 122b are at least a part of the guide through groove 122 mentioned above. At this time, the linear guide surface 123 mentioned above may include a first linear guide surface 123a for forming at least a part of the first guide groove 122a, and a second linear guide surface 123b for forming at least a part of the second guide groove 122b. Correspondingly, the arc guide surface 124 mentioned above may include a first arc guide surface 124a for forming at least a part of the first guide groove 122a, and a second arc guide surface 124b for forming at least a part of the second guide groove 122b.

[0089] The first guide groove 122a and the second guide groove 122b may be connected to each other. Of course, according to actual conditions, they may also be configured to be isolated from each other.

[0090] In some embodiments, the first type transmission member 111 can at least slide along the first direction X1 relative to the guide seat 120 under the guidance of the first guide section 121a, and / or the first type transmission member 111 can at least rotate around the third rotation axis L3 relative to the guide seat 120 under the guidance of the first guide section 121a. In order to further make the transmission assembly 110 move smoothly and reduce the possibility of motion jamming, refer to Figure 2 and Figure 4 As shown, during the sliding process of the first type transmission member 111 relative to the guide seat 120 along the first direction X1, the value range of the angle α between the common perpendicular line of the first rotation axis L1 and the second rotation axis L2 and the first direction X1 is 120°≤α<180°. When the first type transmission member 111 can slide a certain distance relative to the guide seat 120 along the first direction X1 under the guidance of the first guide section 121a, and can rotate a certain angle around the third rotation axis L3 during the movement, the above configuration can enable the first type transmission member 111 to smoothly adjust from sliding relative to the guide seat 120 to rotating relative to the guide seat 120, and at the same time enable the power provided by the driver 11 to be transmitted to the first type transmission member 111 to a large extent through the second type transmission member 112, thereby ensuring the transmission efficiency.

[0091] In some embodiments, the transmission assembly 110 further includes: a connector 113. The connector 113 is disposed between the first type transmission member 111 and the convertible cover 1a of the vehicle to connect the first type transmission member 111 and the convertible cover 1a of the vehicle; in a specific solution, the connector is, for example, connected between the second end A2 of the first type transmission member 111 and the convertible cover 1a. The connector 113 is integrally formed with the first type transmission member 111 or is fixedly connected. The force transmission from the first type transmission member 111 to the convertible cover 1a is achieved by providing the connector 113. At this time, the specific size of the connector 113 can be configured according to the vehicle conditions, so that when the first type transmission member 111 moves, the convertible cover 1a can move in a larger or smaller range according to the size of the connector 113, so that the transmission device 100 can be more suitable for integration on the corresponding vehicle.

[0092] In some embodiments, the connecting member 113 and the second type transmission member 112 are respectively disposed at opposite ends of the first type transmission member 111 , so that the connecting member 113 is relatively far away from the second type transmission member 112 , which facilitates the installation of the two on the first type transmission member 111 .

[0093] It is understood that according to the second aspect of the present application, referring to Figure 1As shown, the transmission device 100 provided by the present application can be combined with the driver 11 to form at least a part of a driving device 10, which serves as a power source for driving the activity of a target object such as a convertible cover 1a of a vehicle, so that the driving device 10 can at least be used to drive the convertible cover 1a of the vehicle to open or close the convertible cover 1a of the vehicle. The driving device 10 has all the beneficial effects of the above-mentioned transmission device 100, which will not be described in detail in the present application.

[0094] In some embodiments, the driver 11 is configured as a linear driver to drive at least a portion of the transmission device 100 to move in a straight line. As an exemplary illustration of a specific solution, the driver 11 may be, for example, a linear motor, an electric telescopic rod, or the like.

[0095] As a specific solution, the driver 11 can be hinged on the guide seat 120 at one end and rotatably connected to the transmission assembly 110 at the other end, so that the driver 11 and the transmission assembly 110 can move relative to the vehicle body 1b, and when the driver 11 is working, it drives the transmission assembly 110 to move along a preset path relative to the guide seat 120.

[0096] According to the third aspect of the present application, referring to Fig.12 As shown, a vehicle 1 is provided, the vehicle 1 comprising the above transmission device 100, or comprising the above drive device 10. The vehicle 1 has all the beneficial effects of the above transmission device 100 or drive device 10, which will not be described in detail in this application.
