DETAILED DESCRIPTION

[0033] Embodiments of the present application 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 intended to be used to explain the present application, and should not be construed as limiting the present application.

[0034] In the description of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] Combine the following Figure 1-Figure 6 The connecting rod driving device 10 and the vehicle 100 having the connecting rod driving device 10 according to the embodiment of the present application are described in detail.

[0036] See also Figure 1 , Figure 2 As shown, the connecting rod driving device 10 according to the embodiment of the present application may include a first electric strut 1 and a first connecting rod assembly 2, the first electric strut 1 is connected to the first connecting rod assembly 2 (for example, one end of the first electric strut 1 may be connected to the first connecting rod assembly 2), and the first electric strut 1 is used to drive the first connecting rod assembly 2 to move.

[0037] In some embodiments, the first link assembly 2 has a convertible top connection structure 23. The convertible top of the vehicle 100 is suitable for being installed on the convertible top connection structure 23, and when the convertible top connection structure 23 moves, the convertible top is driven to move.

[0038] Specifically, the first electric strut 1 is connected to the first connecting rod assembly 2, so that the force generated by the first electric strut 1 can be transmitted to the first connecting rod assembly 2 in a relatively stable form, and the parameters such as the extension speed, length, and output thrust or pulling force of the first electric strut 1 can be accurately adjusted through the current signal, thereby more accurately controlling the movement of the first connecting rod assembly 2, improving the stability and movement accuracy of the connecting rod driving device 10, thereby improving the position accuracy of the convertible connecting structure 23, and making the position of the convertible more accurate. At the same time, because the driving method of the hydraulic piston rod is cancelled, there is no need to regularly check and maintain the hydraulic stability, which reduces costs.

[0039] In the related art, the connecting rod driving device usually controls the reciprocating motion of the support rod by injecting hydraulic pressure at both ends of the hydraulic piston rod, thereby driving the connecting rod assembly, but the accuracy of the hydraulic piston control is too low.

[0040] According to the connecting rod driving device 10 of the embodiment of the present application, the first electric strut 1 is connected to the first connecting rod assembly 2, so that the first electric strut 1 can more accurately drive the movement of the first connecting rod assembly 2, thereby improving the stability and movement accuracy of the connecting rod driving device 10, thereby improving the position accuracy of the first connecting rod assembly 2.

[0041] In addition, since the hydraulic system needs to arrange certain pipelines, the fluid running resistance is large due to the influence of the environment, and the intuitive manifestation is the action lag, and the hydraulic system needs regular inspection and maintenance, which is costly. The connecting rod drive device 10 of the present application does not need to arrange pipelines, reduces the driving resistance, further improves the driving accuracy, and saves pipeline costs.

[0042] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the connecting rod driving device 10 also includes a base 3, the first electric strut 1 is hingedly connected to the first connecting rod assembly 2, and the first electric strut 1 is hingedly connected to the base 3 (for example, the other end of the first electric strut 1 can be hingedly connected to the base 3). Therefore, the base 3 provides a stable supporting structure for the entire connecting rod driving device 10, ensuring that the first connecting rod assembly 2 can move smoothly according to a predetermined trajectory and method, and also ensuring that the convertible connecting structure 23 on the first connecting rod assembly 2 can move smoothly according to a predetermined trajectory and method.

[0043] In some embodiments of the present application, see Figure 1 , Figure 2As shown, the first connecting rod assembly 2 includes a first main connecting rod 21, and the first electric strut 1 includes a first base 11 and a first strut 12. The first strut 12 can be extended relative to the first base 11, and the first base 11 is hingedly connected to the base 3. Specifically, the first base 11 is hingedly connected to the base 3 at the third hinge point 63 of the base 3. The first connecting rod assembly 2 is a multi-link mechanism. The movement of the entire first connecting rod assembly 2 can be accurately controlled by the first electric strut 1, which improves the accuracy and stability of the movement of the first connecting rod assembly 2.

[0044] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the first support rod 12 is hingedly connected to the first main connecting rod 21 at a first hinge point 61, and the first main connecting rod 21 is also hingedly connected to the base 3 at a second hinge point 62. The first hinge point 61 and the second hinge point 62 are arranged at intervals.

[0045] Specifically, the first main connecting rod 21 is hingedly connected to the first support rod 12 at the first hinge point 61 and is hingedly connected to the base 3 at the second hinge point 62, thereby enhancing the stability of the first connecting rod assembly 2 when subjected to force and ensuring the reliable operation of the entire connecting rod driving device 10.

[0046] In some embodiments, the first base 11 has a ball head structure at one end close to the base 3, and the base 3 has a ball head connection structure at the third hinge point 63. The ball head structure of the first base 11 and the ball head connection structure of the base 3 can be limited by a spring clip. Specifically, the cooperation of the ball head structure and the ball head connection structure gives the first base 11 a multi-degree-of-freedom motion characteristic relative to the base 3, so that the first electric support rod 1 can be universally rotated relative to the base 3, ensuring the smooth movement of the first connecting rod assembly 2, avoiding the risk of jamming, etc., and at the same time, increasing the assembly efficiency of the connecting rod driving device 10.

[0047] In some embodiments, the first base 11 has a ball head connection structure at one end close to the base 3, and the base 3 has a ball head structure at the third hinge point 63. The ball head connection structure of the first base 11 and the ball head structure of the base 3 can be limited by a retaining spring.

[0048] In some embodiments, the first electric strut 1 has a U-shaped pin at the first hinge point 61, and the first main connecting rod 21 has a rivet shaft at the first hinge point 61. The rivet shaft of the first main connecting rod 21 passes through the mounting hole on the U-shaped pin of the first electric strut 1, and a sleeve is provided at the sleeve between the rivet shaft and the mounting hole on the U-shaped pin.

[0049] Specifically, there is a certain amount of interference between the sleeve and the rivet shaft, and between the sleeve and the mounting hole on the U-shaped latch, which can provide torque for the first main connecting rod 21, ensuring the stability of the first main connecting rod 21 when starting, running, and stopping. At the same time, the above interference can reduce the amount of shaking during the operation of the entire mechanism. At the connection part where a large torque needs to be transmitted (such as the first hinge point 61), by increasing the amount of interference between the latch and the sleeve, sufficient friction can be generated between the latch and the sleeve to prevent the two from rotating relative to each other during the working process, reduce the amount of shaking during the operation of the first connecting rod assembly 2, make the connection more secure, and at the same time, increase the assembly efficiency of the connecting rod drive device 10.

[0050] In some embodiments, the first electric strut 1 has a rivet shaft at the first hinge point 61, the first main connecting rod 21 has a U-shaped pin at the first hinge point 61, and the rivet shaft of the first electric strut 1 is connected to the U-shaped pin of the first hinge point 61 through a bushing.

[0051] In some embodiments, the first electric strut 1 has a ball head structure at the first hinge point 61, and the first main connecting rod 21 has a ball head connection structure at the first hinge point 61, and the ball head structure of the first electric strut 1 rotates with the ball head connection structure of the first hinge point 61.

[0052] In some embodiments, the first electric strut 1 has a ball head connection structure at the first hinge point 61, and the first main connecting rod 21 has a ball head structure at the first hinge point 61, and the ball head connection structure of the first electric strut 1 rotates with the ball head structure of the first hinge point 61.

[0053] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the first electric strut 1 includes a first spring 13, the first spring 13 is at least sleeved outside the first strut 12, the first spring 13 is connected to the first base 11 (for example, one end of the first spring 13 is connected to the first base 11), the first spring 13 is also connected to the first strut 12 (for example, one end of the first spring 13 is connected to the first strut 12), and the first spring 13 can be stretched and compressed. Specifically, by arranging the first spring 13 outside the first strut 12, the force transmission of the entire connecting rod driving device 10 is made more stable and continuous, avoiding the occurrence of stuck and unsmooth movement of the first connecting rod assembly 2 due to sudden changes in force, and ensuring the smoothness and stability of the first connecting rod assembly 2.

[0054] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the first connecting rod assembly 2 is a multi-link mechanism, and the first connecting rod assembly 2 also includes a plurality of first driven connecting rods 22. When the first main connecting rod 21 moves, it is suitable for driving the plurality of first driven connecting rods 22 to move.

[0055] Specifically, the plurality of first driven links 22 move under the drive of the first main link 21. Through the combination of factors such as different lengths, hinge point positions, and relative angle relationships between the first main link 21 and each first driven link 22, more rich and complex motion trajectory changes can be achieved, so that the first link assembly 2 can be flexibly adjusted according to the actual situation in the vehicle 100, thereby improving the application scope of the link driving device 10. At the same time, when the force output by the first electric strut 1 is transmitted to the first main link 21, the first main link 21 transmits the force to the plurality of first driven links 22 in a dispersed manner, thereby avoiding stress concentration in a certain place, reducing the risk of damage to the first link assembly 2 due to excessive local force, extending the service life of the first link assembly 2, and improving the reliability of the link driving device 10.

[0056] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, a convertible connecting structure 23 is provided on the first main connecting rod 21 and / or the first driven connecting rod 22. Thus, the convertible connecting structure 23 makes the connection between the convertible and the first main connecting rod 21 or the first driven connecting rod 22 more direct and standardized. During the assembly process of the vehicle 100, the installer can quickly and accurately connect the convertible to the first main connecting rod 21 and / or the first driven connecting rod 22 according to the convertible connecting structure 23, thereby reducing the problems of long installation time and installation errors caused by unclear or complicated connection methods, and improving the assembly efficiency of the entire vehicle 100.

[0057] Optionally, the number of convertible connecting structures 23 in the first connecting rod assembly 2 may be one, two, three or more.

[0058] In some embodiments, the convertible connecting structure 23 is disposed on the first main connecting rod 21 .

[0059] In some embodiments, the convertible connecting structure 23 is disposed on the first driven link 22 .

[0060] In some embodiments, a portion of the convertible connecting structure 23 is disposed on the first main connecting rod 21 , and another portion is disposed on the first driven connecting rod 22 .

[0061] For example, there are five convertible top connection structures 23 , and all of the five convertible top connection structures 23 are arranged on the first driven link 22 .

[0062] The first connecting rod assembly 2 can be a four-link assembly, a five-link assembly, a six-link assembly, a seven-link assembly, etc. The connecting rod assembly is a common structure in the mechanical field. The specific number of rods in the first connecting rod assembly 2, the connection relationship between the first driven link 22 and the first main link 21, and the relationship between the first driven link 22 and other first driven links 22 are not limited here.

[0063] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the connecting rod driving device 10 also includes a second electric strut 4 and a second connecting rod assembly 5, the second electric strut 4 is hingedly connected to the second connecting rod assembly 5 (for example, one end of the second electric strut 4 is hingedly connected to the second connecting rod assembly 5), the second electric strut 4 is hingedly connected to the base 3 (for example, the other end of the second electric strut 4 is hingedly connected to the base 3), and the second electric strut 4 is used to drive the second connecting rod assembly 5 to move.

[0064] In some embodiments, the second linkage assembly 5 has a windshield connecting structure 51 .

[0065] Specifically, the second electric strut 4 is hingedly connected to the second connecting rod assembly 5, so that the second electric strut 4 controls the movement of the second connecting rod assembly 5 after receiving the electrical signal, thereby driving the windshield connecting structure 51 to move. When the convertible connecting structure 23 is connected to the convertible and the windshield connecting structure 51 is connected to the rear windshield 20, the second electric strut 4 is hingedly connected to the second connecting rod assembly 5 to realize the driving of the rear windshield 20 of the vehicle 100, so that the connecting rod driving device 10 can not only control the opening and closing of the convertible, but also control the movement of the rear windshield 20. At the same time, during the opening and closing process of the convertible, the second electric strut 4 and the second connecting rod assembly 5 control the rear windshield 20 to avoid the travel space of the first electric strut 1 and the first connecting rod assembly 2, so as to prevent the convertible from colliding with the rear windshield 20 and avoid damage to the components of the vehicle 100.

[0066] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the hinge position of the second electric strut 4 and the base 3 is located on the side of the hinge position of the first electric strut 1 and the base 3 facing the front of the vehicle. Specifically, by placing the hinge position of the second electric strut 4 and the base 3 in front (facing the front of the vehicle), the first electric strut 1, the second electric strut 4, the first connecting rod assembly 2 and the second connecting rod assembly 5 can be distributed more orderly and compactly inside the vehicle 100, avoiding mutual interference and spatial conflict between the components due to unreasonable hinge positions.

[0067] In some embodiments of the present application, see Figure 1 , Figure 2As shown, the second connecting rod assembly 5 includes a second main connecting rod 52, the second electric strut 4 includes a second base 41 and a second supporting rod 42, the second supporting rod 42 can be extended relative to the second base 41, the second base 41 is hingedly connected to the base 3, and the second supporting rod 42 is hingedly connected to the second main connecting rod 52. Specifically, the second supporting rod 42 is connected to the second main connecting rod 52 through a hinge, and the force generated when the second supporting rod 42 is extended relative to the second base 41 can be effectively transmitted to the second main connecting rod 52 through the hinge point, and then transmitted to other places of the second connecting rod assembly 5 through the second main connecting rod 52, and finally acts on the windshield connecting structure 51, ensuring the stability and accuracy of the movement of the second connecting rod assembly 5.

[0068] In some embodiments not shown in the figure, the second electric strut 4 also includes a second spring, which is at least sleeved outside the second strut 42, one end of the second spring is connected to the second base 41, and one end of the second spring is connected to the second strut 42, and the second spring can be stretched and compressed. Specifically, by arranging the second spring outside the second strut 42, the force transmission of the entire connecting rod driving device 10 is made more stable and continuous, avoiding the occurrence of the second connecting rod assembly 5 being stuck or not smooth due to the sudden change of force, and ensuring the smoothness and stability of the second connecting rod assembly 5.

[0069] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the second connecting rod assembly 5 is a multi-link mechanism, and the second connecting rod assembly 5 also includes a plurality of second driven connecting rods 53. When the second main connecting rod 52 moves, it is suitable for driving the plurality of second driven connecting rods 53 to move.

[0070] Specifically, the plurality of second driven links 53 move under the drive of the second main link 52. Through the combination of factors such as different lengths, hinge point positions, and relative angle relationships between the second main link 52 and each second driven link 53, more rich and complex motion trajectory changes can be achieved, so that the second link assembly 5 can be flexibly adjusted according to the actual situation in the vehicle 100, thereby improving the application scope of the link driving device 10. At the same time, when the force output by the second electric strut 4 is transmitted to the second main link 52, the second main link 52 transmits the force to the plurality of second driven links 53 in a dispersed manner, thereby avoiding stress concentration in a certain place, reducing the risk of damage to the second link assembly 5 due to excessive local force, extending the service life of the second link assembly 5, and improving the reliability of the link driving device 10.

[0071] In some embodiments of the present application, see Figure 1 , Figure 2As shown, a windshield connecting structure 51 is provided on the second main connecting rod 52 and / or the second driven connecting rod 53. Therefore, the windshield connecting structure 51 is provided on the second main connecting rod 52 and / or the second driven connecting rod 53, providing a clear positioning reference for the installation of the windshield. During the assembly process of the vehicle 100, the operator can accurately connect the windshield with the second main connecting rod 52 and the second driven connecting rod 53 according to the windshield connecting structure 51, thereby avoiding the position deviation problem caused by unclear positioning during installation and improving the precision and accuracy of installation.

[0072] In some embodiments, the windshield connecting structure 51 is disposed on the second main connecting rod 52 .

[0073] In some embodiments, the windshield connecting structure 51 is disposed on the second driven link 53 .

[0074] In some embodiments, the windshield connecting structure 51 is disposed on the second main link 52 and the second driven link 53 .

[0075] The second connecting rod assembly 5 can be a three-link assembly, a four-link assembly, a five-link assembly, a six-link assembly, a seven-link assembly, etc. The connecting rod assembly is a common structure in the mechanical field. The specific number of rods in the second connecting rod assembly 5, the connection relationship between the second driven link 53 and the second main link 52, and the relationship between the second driven link 53 and other second driven links 53 are not limited here.

[0076] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the second electric strut 4 and the first electric strut 1 are individually controlled by timing. Specifically, the second electric strut 4 and the first electric strut 1 can be individually controlled by timing to make more precise adjustments to the movement process of the first connecting rod assembly 2 and the second connecting rod assembly 5, so that the start and stop of the first connecting rod assembly 2 and the second connecting rod assembly 5 will not interfere with each other, thereby improving the stability and reliability of the connecting rod driving device 10.

[0077] See also Figure 1 , Figure 2 , Figure 6 As shown, a vehicle 100 according to another embodiment of the present application includes the above-mentioned connecting rod driving device 10.

[0078] According to the vehicle 100 of another embodiment of the present application, its connecting rod driving device 10 is connected to the first connecting rod assembly 2 through the first electric strut 1, so that the first electric strut 1 can more accurately drive the movement of the first connecting rod assembly 2, thereby improving the stability and movement accuracy of the connecting rod driving device 10, thereby improving the position accuracy of the first connecting rod assembly 2.

The vehicle 100 also includes a convertible and a rear windshield 20, the convertible is installed on the convertible connecting structure 23, and the rear windshield 20 is installed on the windshield connecting structure 51. Specifically, the first electric strut 1 drives the first connecting rod assembly 2 to move, and the movement of the convertible connecting structure 23 in the first connecting rod assembly 2 drives the convertible to open and close the operation. Similarly, the second electric strut 4 drives the second connecting rod assembly 5 to move, and the movement of the windshield connecting structure 51 in the second connecting rod assembly 5 drives the rear windshield 20 to lift and lower the operation.

[0080] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the vehicle 100 has a passenger compartment, and the left and right sides of the passenger compartment are provided with a first electric strut 1, a first connecting rod assembly 2, a second electric strut 4, and a second connecting rod assembly 5. Specifically, the first electric strut 1, the first connecting rod assembly 2, the second electric strut 4, and the second connecting rod assembly 5 are provided on the left and right sides of the passenger compartment, so that the symmetrical driving of the convertible top and the rear windshield 20 of the vehicle 100 can be achieved. This symmetrical layout can evenly distribute the force on both sides of the vehicle 100, avoiding uneven force caused by unilateral driving, thereby ensuring the stability of the vehicle 100 during the process of opening and closing the convertible top and raising and lowering the windshield.

[0081] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the connecting rod driving device 10 further includes a convertible transverse strut 24, which is connected to the convertible connecting structure 23 located on the left and right sides of the passenger compartment. Specifically, the convertible transverse strut 24 supports the convertible, improves the structural strength of the convertible, prevents the convertible from twisting, deformation, etc., and ensures the normal functional state of the convertible.

[0082] In some embodiments, thread grooves are provided on the first base 11 and the first strut 12 at positions corresponding to the two ends of the first spring 13, and the ends of the first spring 13 are screwed into the thread grooves at the corresponding ends. A certain number of clamping circles are provided between the two ends of the first spring 13 and the corresponding thread grooves, for example, the number of clamping circles is not less than 3 circles. Thus, by setting a certain number of clamping circles, the spring can be relatively firmly clamped in the thread groove, thereby ensuring the reliability of the connection between the first spring 13 and the first electric strut 1. When the convertible is fully opened, the first electric strut 1 is extended to the maximum position state, at which time the first spring 13 is in a stretched state. When the convertible is in a fully retracted and folded state, the first electric strut 1 is retracted to the minimum position state, at which time the first spring 13 is in a compressed state.

[0083] In some embodiments, the first electric strut 1 is energized through a controller, and the first strut 12 is extended and retracted relative to the first base 11, thereby realizing the folding and unfolding movement of the first link assembly 2, and the folding and unfolding movement of the first link assembly 2 drives the opening and closing of the convertible. Similarly, the second electric strut 4 is energized through the controller, and the second strut 42 is extended and retracted relative to the second base 41, thereby realizing the folding and unfolding movement of the second link assembly 5, and the folding and unfolding movement of the second link assembly 5 drives the movement of the rear windshield 20.

[0084] The connecting rod driving device 10 is the power source for the convertible and the rear windshield 20. The opening and closing of the convertible and the raising and lowering of the rear windshield 20 each require a set of driving controls. The controller can control the sequential extension and retraction of the first electric strut 1 and the second electric strut 4. Each action switching requires a certain amount of waiting and compensation to ensure a smooth opening or storage process of the convertible. Among them, the first electric strut 1 is the main driving structure and the second electric strut 4 is the auxiliary driving mechanism. The specific operation is as follows:

[0085] like Figure 3 As shown, the connecting rod driving device 10 is in a retracted state; when the convertible needs to be opened, as shown in FIG. Figure 4 As shown, the controller energizes the first electric strut 1, and the first electric strut 1 extends to push the first connecting rod assembly 2 to extend, thereby controlling the convertible to open. At the same time, the controller energizes the second electric strut 4 to make the second electric strut 4 push the second connecting rod assembly 5 to extend, so that the rear windshield 20 moves with the extension of the second connecting rod assembly 5. When the convertible is fully opened, a locking signal is sent to the controller, and the first electric strut 1 and the second electric strut 4 stop moving. Subsequently, as shown in FIG. Figure 5 As shown, the controller energizes the second electric strut 4 so that the second electric strut 4 pulls the second connecting rod assembly 5 to contract, thereby causing the rear windshield 20 to move as the second connecting rod assembly 5 contracts.

[0086] When the convertible needs to be closed, Figure 4As shown, the controller energizes the second electric strut 4, and the second electric strut 4 extends to push the second connecting rod assembly 5 to extend, thereby controlling the rear windshield 20 to move as the second connecting rod assembly 5 extends; as shown in 3, the controller energizes the first electric strut 1 so that the first electric strut 1 pulls the first connecting rod assembly 2 to contract, thereby controlling the convertible to close, and at the same time, the controller energizes the second electric strut 4 so that the second electric strut 4 pulls the second connecting rod assembly 5 to contract, thereby controlling the rear windshield 20 to move as the second connecting rod assembly 5 contracts.
