Description

Technical Field

[0001] The present application relates to the field of automobile braking, and in particular to a vehicle braking mechanism. Background Art

[0002] AEB (Autonomous Emergency Braking) systems are widely used in automobiles to reduce the risk of traffic accidents. These systems typically utilize a cable-operated motor to assist braking. This motor controls the vehicle's brake pedal via a zipper, thereby applying the brakes.

[0003] However, the zipper of the cable motor needs to be fixed by a special zipper fixing bracket. Due to the diversity of vehicle designs, the fixing methods of automobile brake links are also different. Different car models often require special cable motor zipper fixing brackets to ensure that the cable motor can smoothly control the brake pedal to achieve braking.

[0004] However, the existing solution of requiring a separate design of a cable motor fixing bracket for each vehicle model increases design costs and production complexity. In addition, during the actual installation of the zipper fixing bracket and the cable motor, the cable motor fixing bracket may not match the vehicle model, which may result in time-consuming installation or even inability to complete the installation. Summary of the Invention

[0007] A driving device, wherein the driving device is arranged on the connecting rod, and an output end of the driving device is connected to the fixing module;

[0008] The driving device is configured to apply a force to the connecting rod and the pedal so that the connecting rod and the pedal move with the first end as the center, and when the vehicle needs to perform a braking operation, the driving device drives the connecting rod and the pedal toward the fixed module until the connecting rod and the pedal move to the braking position.

[0009] In an embodiment of the present application, the fixing module includes a first fixing module and a second fixing module. The first end of the first fixing module is connected to the first end of the second fixing module, such that the first fixing module and the second fixing module are disposed at an angle.

[0010] The second end of the first fixing module is unilaterally fixed to one side of the fixing member, and the second end of the second fixing module is connected to the output end of the driving device.

[0011] The driving device is configured to apply a force to the connecting rod and the pedal to move in the direction of the second fixing module, so that the connecting rod and the pedal move to the braking position.

[0012] In an embodiment of the present application, the fixing module further includes a third fixing module. The third fixing module is detachably connected to the second fixing module. The third fixing module is configured to be connected to the output end of the driving device. The driving device is configured to apply a force to the connecting rod and the pedal to move in the direction of the third fixing module, so that the connecting rod and the pedal move to the braking position.

[0013] In an embodiment of the present application, at least one mounting hole is provided on the second fixing module, and a through groove adapted to the mounting hole is formed on the third fixing module. The third fixing module is mounted to the second fixing module through the through groove and the mounting hole.

[0014] In an embodiment of the present application, the third fixing module includes a mounting portion and a connecting portion. Among them, a through groove adapted to the mounting hole is formed on the mounting portion.

[0015] The connecting portion is configured to be connected to the output end of the driving device. The driving device is configured to apply a force to the connecting rod and the pedal to move in the direction of the connecting portion, so that the connecting rod and the pedal move to the braking position.

[0016] In an embodiment of the present application, at least three mounting holes are provided on the second fixing module. The at least three mounting holes are configured to be spaced apart along the axial direction of the second fixing module. The mounting portion is configured to selectively cooperate with the mounting holes to be mounted together to adjust the relative position between the third fixing module and the second fixing module.

[0017] In an embodiment of the present application, the mounting portion is disposed horizontally coplanar with the second fixing module, the connecting portion is disposed perpendicular to the second fixing module, and the connecting portion is disposed horizontally with the output end of the driving device.

[0018] A sliding pin and a locking device are provided on the connecting portion. The output end of the driving device is installed between the sliding pin and the locking device, and the output end of the driving device is locked at the installation position by the locking device.

[0019] In an embodiment of the present application, a first through hole is provided at the end of the first fixing module fixed to the fixing member, and the first fixing module is fixed to one side of the fixing member unilaterally through the first through hole.

[0020] In an embodiment of the present application, an auxiliary fixing hole is provided on one side of the second fixing module, and the auxiliary fixing hole is configured to be fixedly installed with the vehicle frame.

[0021] In an embodiment of the present application, the driving device includes at least one of a wire motor and a linear motor.

[0022] In the prior art, usually cable fixing brackets are provided on both sides of the pedal, and the cable fixing brackets and the fixing members are fixed by a double-ear fixing method. Since the sizes of the fixing members of different vehicle models are different, different models of cable fixing brackets need to be selected according to the width of the fixing member, resulting in the need to design corresponding cable fixing brackets separately for different vehicle models, thus increasing the design cost and production complexity. Moreover, during the actual installation of the cable fixing bracket and the wire motor, problems such as the mismatch between the wire motor fixing bracket and the vehicle model are likely to occur, resulting in time-consuming installation and even the phenomenon that the wire motor cannot be installed.

[0023] In the braking mechanism of the vehicle provided by the present application, the fixing module is fixed to one side of the fixing member included in the braking module unilaterally, that is, the fixing method between the fixing module and the braking module is a single-ear fixing method. Moreover, the fixing module is connected to the output end of the driving device, and the driving device can apply a force to the connecting rod and the pedal in the braking module to drive the connecting rod and the pedal to move, so that when the vehicle needs to perform a braking operation, it can be determined that the connecting rod and the pedal move towards the fixing module, so that the connecting rod and the pedal move to the braking position to make the vehicle perform a braking operation.

[0024] In the braking mechanism provided by the present application, the fixing module plays the role of the cable fixing bracket in the prior art, and the fixing method between the fixing module and the braking module is a single-ear fixing method. Compared with the double-ear fixing method in the prior art, the width of the fixing member does not need to be considered, so the influence of different vehicle models on the cable fixing bracket does not need to be considered, and there is no need to design a wire motor fixing bracket separately for each vehicle model, thus saving the design cost and reducing the production complexity. Moreover, the braking mechanism is applicable to various vehicle models and will not show a mismatch with the vehicle model, so it can also improve the assembly versatility.

[0040] Now, various exemplary embodiments of the present application will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present application.

[0041] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation on the present application, its application, or its use.

[0042] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and devices should be regarded as part of the specification.

[0043] It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0044] The following describes the specific implementation manners of the present application with reference to the accompanying drawings.

[0045] In this document, "upper", "lower", "front", "rear", "left", "right", etc. are only used to represent the relative positional relationship between relevant parts, rather than defining the absolute positions of these relevant parts.

[0046] In this document, "first", "second", etc. are only used for distinguishing each other, rather than indicating importance, order, and the prerequisite for mutual existence, etc.

[0047] In this document, "equal", "same", etc. are not strict mathematical and / or geometric limitations, and also include the allowable errors that can be understood by those skilled in the art and are allowed in manufacturing or using, etc.

[0048] For ease of understanding, the following refers to Figures 1 to 9 , and in combination with an embodiment, the specific structure and working principle of the braking mechanism of the present application are described in detail.

[0049] This application relates to an AEB (Autonomous Emergency Braking) system. The AEB system can help a vehicle actively brake in case of a possible collision to avoid an accident or reduce the severity of the collision. It detects whether there are obstacles or dangers ahead through sensors and algorithms, and actively intervenes when the driver fails to react in time, enabling the vehicle to perform a braking operation.

[0050] Normally, a braking device is provided in a vehicle. The braking device generally consists of a pedal, a connecting rod connected to the pedal, and a fixing member connecting the connecting rod and the vehicle. The connecting rod is configured to drive the pedal to move around the connection end of the connecting rod and the fixing member, so that the vehicle enters a braking state or releases the braking state. The AEB system is a set of automatic emergency braking systems installed on the braking device. When the vehicle needs to enter a braking state, the AEB system can simulate the user's braking and spontaneously drive the connecting rod and the pedal to move to the braking position.

[0051] In the design of existing AEB systems, a wire-pulling motor is usually arranged on the connecting rod, and a wire-pulling motor cable fixing bracket is fixedly arranged on the fixing member. The simulation of braking is achieved by the cooperation of the wire-pulling motor and the wire-pulling motor cable fixing bracket. And in order for the wire-pulling motor cable fixing bracket to be stably fixed on the fixing member, a double-ear fixing method is usually used to fix the two, that is, both sides of the wire-pulling motor cable fixing bracket are fixedly connected to both sides of the fixing member. However, the double-ear fixing method requires selecting different models of wire-pulling motor cable fixing brackets according to the width of the fixing member. Also, since the sizes of the fixing members of different vehicle models are different, in order to better fix the wire-pulling motor cable fixing bracket, it is necessary to customize different models of wire-pulling motor cable fixing brackets for different vehicle models. This brings great inconvenience to the installation of the wire-pulling motor cable fixing bracket. If an ill-fitting wire-pulling motor cable fixing bracket is used, it may lead to time-consuming installation or even the situation where the installation cannot be completed.

[0052] Based on this, this application provides a braking mechanism that can simulate the user's braking and spontaneously drive the connecting rod and the pedal to move to the braking position when the vehicle needs to brake. Refer to Figure 1 、 Figure 3, the braking mechanism includes a brake module 1, a fixing module 2 and a driving device. Among them, the brake module 1 includes a fixing member 12, a connecting rod 13 and a pedal 14. The fixing member 12 is fixedly connected to the vehicle frame. The connecting rod 13 has opposite first end 131 and second end 132. The first end 131 is connected to the fixing member 12, and the second end 132 is connected to the pedal 14. The fixing module 2 is fixedly connected to one side of the fixing member 12. The driving device is arranged on the connecting rod 13, and the output end of the driving device is connected to the fixing module 2. The driving device is configured to apply a force to the connecting rod 13 and the pedal 14, so that the connecting rod 13 and the pedal 14 move with the first end 131 as the center of the circle. And, when the vehicle needs to perform active braking, the driving device drives the connecting rod 13 and the pedal 14 to move towards the fixing module 2 until the connecting rod 13 and the pedal 14 move to the braking position to complete braking, thereby realizing the braking operation of the vehicle.

[0053] In this application, the fixing module 2 is fixed on the fixing member 12, which plays the role of connecting with the output end of the driving device, so that the driving device can drive the connecting rod 13 and the pedal 14 to move towards the fixing module 2 when outputting, which is the same as the zip fixing bracket described above. Since this application improves the fixing method of the zip fixing bracket in the prior art, which is fixed on both sides of the fixing member 12 by double ears, to the fixing method that the fixing module 2 is fixed on one side of the fixing member 12 by a single ear. On the basis of retaining the original function of the fixing member 12, the fixing module 2 does not need to consider the size of the fixing member 12 and can be adapted to the fixing member 12 of any vehicle model for installation, so that the fixing module 2 can be adapted to more different vehicle types and improves the assembly versatility of the fixing module 2. In addition, the fixing module 2 adopts the method of fixing to one side of the fixing member 12, and can also flexibly adjust the installation position of the fixing module 2 according to the actual installation environment to reduce the interference of the fixing module 2 on the moving track of the connecting rod 13.

[0054] In the braking mechanism provided in this application, the fixing module 2 plays the role of the zip fixing bracket in the prior art, and the fixing method between the fixing module 2 and the brake module 1 is a single-ear fixing method. Compared with the double-ear fixing method in the prior art, it does not need to consider the width of the fixing member 12. Therefore, it does not need to consider the influence of different vehicle models on the fixing module 2, and does not need to design the fixing module 2 separately for each vehicle model. Therefore, the design cost of the fixing module 2 is saved and the production complexity is reduced. And, this braking mechanism is applicable to various vehicle models and will not have the situation of not matching the vehicle model. Therefore, it can also improve the assembly versatility.

[0055] In an embodiment of this application, in order to ensure that the direction of the connecting rod 13 moving with the first end 131 of the connecting rod 13 as the center of the circle will not deviate, refer to Figure 1 、 Figure 3, ribs 121 extending outward along the surface of the fixing member 12 are further provided on the fixing member 12. The ribs 121 are in guiding cooperation with the connecting rod 13 to limit the deflection angle of the connecting rod 13 during the movement of the connecting rod 13. Two ribs 121 are provided and are arranged on both sides of the fixing member 12. The connecting rod 13 will move between the areas surrounded by the two ribs 121 during the movement, so as to play a guiding role in the moving direction of the connecting rod 13.

[0056] In an embodiment of the present application, assembly holes 122 for cooperating with the fixing module 2 for installation are further provided on the left and right sides of the fixing member 12. In order to further improve the assembly versatility of the fixing module 2, the fixing module 2 in the present application has the performance of being assembled in two ways, positive and negative, that is, the fixing module 2 can be installed by selecting the assembly hole 122 on either the left or right side according to the actual installation environment, so as to improve the assembly versatility of the braking device of the present application and enable it to adapt to more different installation environments.

[0057] In an application scenario of the present application, refer to Figure 3 , during the process that the braking mechanism receives the braking instruction of the AEB system and executes the braking instruction, the driving device drives the connecting rod 13 to move towards the direction where the fixing module 2 is located. Since the driving device is fixedly connected to the connecting rod 13, the connecting rod 13 will move downward with the first end 131 of the connecting rod 13 as the center until the connecting rod 13 moves to a preset position, that is, moves to the braking position. During the movement of the connecting rod 13, the pedal 14 fixedly connected to the connecting rod 13 will also move to the braking position together with the connecting rod 13. After the pedal 14 moves to the braking position, the vehicle brakes, that is, the vehicle executes a braking operation.

[0058] When the connecting rod 13 and the pedal 14 are in the braking position, during the process that the braking mechanism receives the brake release instruction of the AEB system and executes the brake release instruction, the driving device outputs in the reverse direction to make the connecting rod 13 have a moving tendency away from the direction where the fixing module 2 is located. Since the driving device is fixedly connected to the connecting rod 13, the connecting rod 13 will move upward with the first end 131 of the connecting rod 13 as the center until the connecting rod 13 moves to a preset position, that is, moves to the brake release position. During the movement of the connecting rod 13, the pedal 14 fixedly connected to the connecting rod 13 will also move to the brake release position together with the connecting rod 13. After the pedal 14 moves to the brake release position, the vehicle releases the brake.

[0059] In an embodiment of the present application, the brake module 1 further includes a reset module. The reset module is arranged between the fixing member 12 and the connecting rod 13 and is configured to enable the connecting rod 13 to be located at the initial position, and when the connecting rod 13 is at other positions, it can be reset to the initial position again under the action of the reset module.

[0060] In an application scenario of the present application, when the connecting rod 13 and the pedal 14 are in the braking position, after the braking mechanism receives the brake release instruction from the AEB system, it only needs to stop the operation of the driving device, and the connecting rod 13 can drive the connecting rod 13 and the pedal 14 to move upward along the first end portion 131 of the connecting rod 13 to the initial position under the action of the reset module, thereby completing the execution of the brake release instruction. Of course, it can also be that the driving device outputs in the reverse direction to loosen the connection with the fixed module 2, and under the cooperation of the reset module, the connecting rod 13 always has a moving tendency away from the direction where the fixed module 2 is located. As the driving device moves further away, the connecting rod 13 gradually moves to the initial position to complete the execution of the brake release instruction. The present application does not impose too many restrictions here.

[0061] The reset module can be a compression spring, a torsion spring, a servo motor, a hydraulic auxiliary reset device, etc. Those skilled in the art can select and design according to actual needs. The present application does not impose too many restrictions here.

[0062] In an embodiment of the present application, referring to Figure 4 the view direction of, for the convenience of description, the upper, lower, left, and right directions of the view are defined. It should be noted that the definition of this direction is only used to clearly illustrate the content of the present application and does not impose any limitation on the protection scope of the present application.

[0063] In order to further improve the installation versatility of the braking mechanism and enable the fixed module 2 to better cooperate with the driving device to achieve the purpose of braking, the fixed module 2 includes a first fixed module 21 and a second fixed module 22. The first end portion of the first fixed module 21 is connected to the first end portion of the second fixed module 22, so that the first fixed module 21 and the second fixed module 22 are arranged at an angle.

[0064] Continuing to refer to Figure 4 the view direction of, the first end portion of the first fixed module 21 is the upper part of the first fixed module 21, the second end portion of the first fixed module 21 is the lower part of the first fixed module 21, the first end portion of the second fixed module 22 is the right side portion of the second fixed module 22, and the second end portion of the second fixed module 22 is the left side portion of the second fixed module 22.

[0065] The second end portion of the first fixed module 21 is unilaterally fixed to one side of the fixing member 12, and the second end portion of the second fixed module 22 is connected to the output end of the driving device. The driving device is configured to apply a force to the connecting rod 13 and the pedal 14 to move in the direction of the second fixed module 22, so that the connecting rod 13 and the pedal 14 move to the braking position.

[0066] Combined with Figure 3, by extending the length of the first fixing module 21, after the second end of the first fixing module 21 is unilaterally fixed to one side of the fixing member 12, space can still be left for the installation position of the second fixing module 22, so that the fixing module 2 can effectively avoid the rib 121 of the fixing member 12 and the movement track of the connecting rod 13, which is beneficial to further expand the installation environment of the fixing module 2 of the present application and enable it to be adapted to more different types of vehicles.

[0067] In an embodiment of the present application, for the convenience of processing, the included angle between the first fixing module 21 and the second fixing module 22 is 90°. Of course, the included angle between the first fixing module 21 and the second fixing module 22 can also be any angle between 0° and 360°, and the present application does not limit this too much here.

[0068] In an embodiment of the present application, referring to Figure 3 , a first through hole 211 is provided at the end of the first fixing module 21 fixed to the fixing member 12, and the first fixing module 21 is unilaterally fixed to one side of the fixing member 12 through the first through hole 211 to realize the fixed connection between the fixing module 2 and the fixing member 12.

[0069] In an embodiment of the present application, in order to further improve the installation stability of the fixing module 2 and reduce the influence of unilateral installation on the fixing module 2, an auxiliary fixing hole 222 is provided on one side of the second fixing module 22, and the auxiliary fixing hole 222 is configured to be fixedly installed with the vehicle frame.

[0070] In a specific application scenario of the present application, referring to Figure 2 、 Figure 3 , the fixing member 12 is usually arranged on the vehicle frame. After the first fixing module 21 is assembled with the fixing member 12, the second fixing module 22 can seemingly be arranged in a fitting manner with the vehicle frame. In order to alleviate the instability of the unilateral fixing between the fixing module 2 and the fixing member 12, the second fixing module 22 is fixedly connected to the vehicle frame through the auxiliary fixing hole 222 on the second fixing module 22, so that the fixing module 2 is more stably connected to the vehicle frame.

[0071] In an embodiment of the present application, referring to the view direction of Figure 4 , the auxiliary fixing hole 222 is provided on the upper or lower side of the second fixing module 22, or can also be provided at the top of the left part, and the present application does not limit this too much here.

[0072] In an embodiment of the present application, referring to Figure 5 、 Figure 6, the fixing module 2 of the present application further includes a third fixing module 23, the third fixing module 23 is detachably connected to the second fixing module 22, the third fixing module 23 is configured to be connected to the output end of the driving device, and the driving device is configured to apply a force to the connecting rod 13 and the pedal 14 to move in the direction of the third fixing module 23, so that the connecting rod 13 and the pedal 14 move to the braking position.

[0073] In an application scenario of the present application, if the first fixing module 21 and the second fixing module 22 are directly installed on the fixing member 12, due to different design styles of different vehicle types, the second fixing module 22 and the output end of the driving device will not be on the same horizontal plane at this time. As a result, when the driving device outputs, it will cause wear to the driving device due to the deviation of the output angle. Therefore, in order to make the output end of the driving device and its connection end with the fixing module 2 on the same horizontal plane, the present application adds a third fixing module 23 detachably connected to the second fixing module 22 on the basis of the second fixing module 22, so that the output end of the driving device is as horizontally coplanar with the third fixing module 23 as possible. In this way, when the driving device drives the connecting rod 13 to drive the pedal 14 to move to the braking position, the third fixing module 23 can reduce the wear caused to the driving device, which is beneficial to extending the service life of the driving device.

[0074] In an embodiment of the present application, in order to reduce the loss of the driving device and shorten the output displacement of the driving device, it is necessary to horizontally set the output direction of the driving device as much as possible with the position where it is connected to the fixing module 2. Refer to Figure 2 , the mounting portion 231 is horizontally coplanar with the second fixing module 22, the connecting portion 232 is perpendicular to the second fixing module 22, and the connecting portion 232 is horizontally arranged with the output end of the driving device;

[0075] A sliding pin 24 and a locking device 25 are provided on the connecting portion 232, the output end of the driving device is installed between the sliding pin 24 and the locking device 25, and the locking device 25 locks the output end of the driving device in the installation position.

[0076] In an application scenario of the present application, refer to Figure 3, the driving device is arranged on the connecting rod 13, and the output end of the driving device is arranged towards the direction where the fixing member 12 is located. After assembling the mounting portion 231 of the third fixing module 23 with the second fixing module 22, the first through hole 211 of the first fixing module 21 is then assembled with the assembly hole 122 on the fixing member 12, thereby completing the assembly between the fixing module 2 and the fixing member 12. After completing the assembly of the fixing module 2 and the fixing member 12, the relative position between the third fixing module 23 and the second fixing module 22 can be adjusted according to the position of the output end of the driving device, so that the connecting portion 232 of the third fixing module 23 is horizontally arranged with the output end of the driving device. Such an arrangement can expand the installation scenarios of the fixing module 2 while minimizing the loss of the driving device, which is beneficial to extending the service life of the driving device.

[0077] In an embodiment of the present application, referring to Figure 2 , at least one mounting hole 221 is provided on the second fixing module 22, and a through groove 2311 adapted to the mounting hole 221 is formed on the third fixing module 23. The third fixing module 23 is installed with the second fixing module 22 through the through groove 2311 and the mounting hole 221. After adjusting the relative position between the third fixing module 23 and the second fixing module 22, the third fixing module 23 is fixedly connected to the second fixing module 22 by bolts in cooperation with the through groove 2311 and the mounting hole 221.

[0078] In an embodiment of the present application, referring to Figure 5 、 Figure 7 , for the purpose of adjusting the relative position between the output end of the driving device and the third fixing module 23, the third fixing module 23 includes a mounting portion 231 and a connecting portion 232. Among them, a through groove 2311 adapted to the mounting hole 221 is formed on the mounting portion 231; the connecting portion 232 is configured to be connected to the output end of the driving device, and the driving device is configured to apply a force to the connecting rod 13 and the pedal 14 to move in the direction of the connecting portion 232, so that the connecting rod 13 and the pedal 14 move to the braking position.

[0079] Through the connecting portion 232, the third fixing module 23 can be better matched with the output end of the driving device. The connecting portion 232 being arranged towards the output end of the driving device enables the driving device to achieve driving the connecting rod 13 and the pedal 14 to move with the maximum displacement with as little output as possible, which is beneficial to improving the working efficiency of the driving device.

The mounting portion 231 is configured to selectively cooperate with the mounting holes 221 to be mounted together, so as to adjust the relative position between the third fixing module 23 and the second fixing module 22. In this actual example, three mounting holes 221 are provided on the second fixing module 22, and the three mounting holes 221 are respectively denoted as the first mounting hole 2211, the second mounting hole 2212, and the third mounting hole 2213. Among them, the first mounting hole 2211, the second mounting hole 2212, and the third mounting hole 2213 are configured to be spaced along the axial direction of the second fixing module 22. The mounting portion 231 is configured to selectively cooperate with the first mounting hole 2211, the second mounting hole 2212, and the third mounting hole 2213 to be mounted, so as to adjust the relative position between the third fixing module 23 and the second fixing module 22.

[0081] In an application scenario of the present application, refer to Figure 5 , Figure 6 , when the mounting portion 231 of the third fixing module 23 and the left side of the second fixing module 22 are assembled together, the connecting portion 232 is disposed to the left relative to the entire fixing module 2. At this time, the mounting portion 231 and the second fixing module 22 can be fixed together through the second mounting hole 2212 and / or the third mounting hole 2213. Refer to Figure 7 , Figure 8 , when the mounting portion 231 of the third fixing module 23 and the right side of the second fixing module 22 are assembled together, the connecting portion 232 is disposed to the right relative to the entire fixing module 2. At this time, the mounting portion 231 and the second fixing module 22 can be fixed together through the second mounting hole 2212 and / or the third mounting hole 2213.

[0082] It can be understood that when the mounting portion 231 is located at the leftmost side of the second fixing module 22, at this time, the mounting portion 231 and the second fixing module 22 can only be fixed together through the first mounting hole 2211. In the current state, the connecting portion 232 is in the leftmost position. Similarly, when the mounting portion 231 is located at the rightmost side of the second fixing module 22, at this time, the mounting portion 231 and the second fixing module 22 can only be fixed together through the third mounting hole 2213. In the current state, the connecting portion 232 is in the rightmost position.

[0083] In another embodiment of the present application, refer to Figure 9, five mounting holes 221 are provided on the second fixing module 22, which are respectively denoted as the first mounting hole 2211, the second mounting hole 2212, the third mounting hole 2213, the fourth mounting hole 2214 and the fifth mounting hole 2215. Among them, the first mounting hole 2211, the second mounting hole 2212, the third mounting hole 2213, the fourth mounting hole 2214 and the fifth mounting hole 2215 are configured to be arranged at intervals along the axial direction of the second fixing module 22. The mounting portion 231 is configured to selectively cooperate with the first mounting hole 2211, the second mounting hole 2212, the third mounting hole 2213, the fourth mounting hole 2214 and the fifth mounting hole 2215 for installation to adjust the relative position between the third fixing module 23 and the second fixing module 22. During the actual installation process, the user can select the mounting hole 221 at any position to fix the relative position between the third fixing module 23 and the second fixing module 22. And due to the increase in the number of mounting holes 221, the relative position between the third fixing module 23 and the second fixing module 22 can be more accurately controlled. Of course, the number of mounting holes 221 can also be any number such as six, seven, etc. Those skilled in the art can select and design according to actual needs, and this application does not impose too many restrictions here.

[0084] In an application scenario of this application, in order to align the position of the connection between the output end of the driving device and the third fixing module 23, when installing the third fixing module 23 on the second fixing module 22, the installation position of the third fixing module 23 on the second fixing module 22 can be adjusted by selecting different mounting holes. For example, when it is necessary to install the third fixing module 23 on the left side of the second fixing module 22, the third fixing module 23 can be cooperatively installed at the leftmost side of the second fixing module 22 through the first mounting hole 2211 and the second mounting hole 2212. Of course, the third fixing module 23 can also be cooperatively installed in the left area of the second fixing module 22 through the second mounting hole 2212 and the third mounting hole 2213. In this way, the relative position between the third fixing module 23 and the second fixing module 22 can be selectively adjusted through multiple mounting holes distributed on the second fixing module 22, so that the third fixing module 23 can be better aligned with the output end of the driving device.

[0085] In another embodiment of the present application, the second fixing module 22 and the third fixing module 23 are connected together by gear meshing and fastened together by bolts. Specifically, the second fixing module 22 and the third fixing module 23 are provided with a matching gear tooth groove structure, and the two are meshed and connected, which can change the relative position between the second fixing module 22 and the third fixing module 23. After adjusting to the preset angle, it is locked by bolts to fix the relative position between the second fixing module 22 and the third fixing module 23. The second fixing module 22 and the third fixing module 23 can also be connected together by pin hole positioning and fastened together by bolts. Specifically, the second fixing module 22 is provided with a plurality of positioning holes, and the third fixing module 23 is provided with a plug pin or a positioning pin. The relative position between the second fixing module 22 and the third fixing module 23 is fixed or adjusted by changing the position of the plug pin. After adjusting to the preset angle, it is locked by bolts to fix the relative position between the second fixing module 22 and the third fixing module 23. Those skilled in the art can select different connection methods according to actual needs, and the present application does not impose too many restrictions here.
