Description

Technical Field

[0002] The hood cable opening mechanism is mainly used to control the opening of the hood. It mainly includes a handle base installed in the cab, a pivot bushing, and an opening handle connected to the pivot bushing. When the hood needs to be opened, the opening handle is turned, which drives the pivot bushing to rotate. The force is then transmitted to the hood through the cable to open the hood.

[0003] In related technologies, the handle base has a mounting groove facing the inner A-pillar panel, and part of the pivot bushing passes through the mounting groove. The reset torsion spring is also located in the mounting groove and sleeved on the pivot bushing. However, the reset torsion spring and the pivot bushing are positioned by the axial cooperation between the inner A-pillar panel and the handle base on the pivot bushing. When installing the handle base, pivot bushing and reset torsion spring, there is a risk that the pivot bushing will fall off the handle base, making installation difficult. Summary of the Invention

[0043] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] The internal opening drive device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0045] Reference Figures 1-9 According to an embodiment of the first aspect of the present invention, the inner opening drive device 100 is used to open the hood of a vehicle. For example, the inner opening drive device 100 can be installed on the inner panel of the A-pillar of the vehicle, or the inner opening drive device 100 can be installed on the instrument panel frame.

[0046] Reference Figures 1-4 The internal opening drive device 100 includes a mounting base 1, a rotating shaft bushing 2, a reset torsion spring 3, and a limiting member 4. The mounting base 1 has an assembly space 121, in which a stop plate 13 is provided. The parts of the assembly space 121 located on both sides of the stop plate 13 in the first direction (refer to direction e1 in the figure) are respectively the first mounting cavity 1211 and the second mounting cavity 1212. The stop plate 13 has a through hole 131 that connects the first mounting cavity 1211 and the second mounting cavity 1212.

[0047] The pivot bushing 2 passes through the through hole 131, and the portion of the pivot bushing 2 extending into the first mounting cavity 1211 abuts against the stop plate 13 in a first direction; for example, the pivot bushing 2 may include a pivot body 21 that can pass through the through hole 131 and a boss structure that protrudes radially outward from the pivot body 21, and the boss structure abuts against the stop plate 13 in a first direction. For example, the pivot bushing 2 is used to connect the unlocking cable 6 of the hood locking structure.

[0048] The limiting member 4 is connected to the part of the rotating shaft bushing 2 that extends into the second mounting cavity 1212, and the limiting member 4 abuts against the stop plate 13 in the first direction; for example, the limiting member 4 can be fixed to the rotating shaft body 21 by fasteners, or the limiting member 4 can be fixed to the rotating shaft body 21 by snap-fit.

[0049] The two torsion arms of the reset torsion spring 3 are respectively connected to the mounting base 1 and the rotating shaft bushing 2. For example, the reset torsion spring 3 includes a torsion spring body and two torsion arms, which are respectively connected to the two ends of the torsion spring body in the first direction.

[0050] When installing the internal drive device 100, the rotating shaft bushing 2 can be inserted through the through hole 131 into the first mounting cavity 1211 and the second mounting cavity 1212 along the direction from the first mounting cavity 1211 to the second mounting cavity 1212. The portion of the rotating shaft bushing 2 extending into the first mounting cavity 1211 is abutted against the stop plate 13. Then, the limiting member 4 is connected to the portion of the rotating shaft bushing 2 located in the second mounting cavity 1212, and the limiting member 4 is abutted against the stop plate 13. Afterward, the two torsion arms of the return torsion spring 3 are respectively connected to the mounting base 1 and the rotating shaft bushing 2. Then, the combined structure of the mounting base 1, the rotating shaft bushing 2, the return torsion spring 3, and the limiting member 4 is installed on the mounting panel. The mounting panel can be the inner A-pillar panel of the vehicle, or it can be the beam structure of the instrument panel frame.

[0051] By setting the portion of the rotating shaft bushing 2 that extends into the first mounting cavity 1211 to abut against one side surface of the stop plate 13 in the first direction, and abutting the limiting member 4 against the other side surface of the stop plate 13 in the first direction, the portion of the rotating shaft bushing 2 that extends into the first mounting cavity 1211 and the limiting member 4 cooperate with each other to fix the rotating shaft bushing 2 relative to the mounting base 1, preventing the rotating shaft bushing 2 from falling off the mounting base 1. This makes the rotating shaft bushing 2 and the mounting base 1 reliably fixed, eliminating the need to use a mounting panel to limit the rotating shaft bushing 2. This makes the assembly of the mounting base 1, the rotating shaft bushing 2 and the limiting member 4 reliably connected, making it easy for operators to hold and place, reducing the installation difficulty of the internal opening drive device 100, reducing the workload of the workers, and improving the assembly efficiency of the internal opening drive device 100.

[0052] According to the internal opening drive device 100 of the present invention, by setting the portion of the rotating shaft bushing 2 that extends into the first mounting cavity 1211 to abut against one side surface of the stop plate 13 in the first direction, and abutting the limiting member 4 against the other side surface of the stop plate 13 in the first direction, the rotating shaft bushing 2 can be reliably fixed relative to the mounting base 1, preventing the rotating shaft bushing 2 from falling off the mounting base 1. It is not necessary to use the mounting panel to limit the rotating shaft bushing 2, so that the assembly of the mounting base 1, the rotating shaft bushing 2 and the limiting member 4 is reliably connected, which is convenient for operators to hold and place, reduces the installation difficulty of the internal opening drive device 100, reduces the workload of the workers, and improves the assembly efficiency of the internal opening drive device 100.

[0053] Reference Figure 3 , Figure 5 and Figure 6 According to some embodiments of the present invention, the mounting base 1 includes a base body 11 and a mounting sleeve 12. The mounting sleeve 12 passes through the base body 11 and defines an assembly space 121. A stop plate 13 is disposed inside the mounting sleeve 12. The portion of the mounting sleeve 12 that defines the first mounting cavity 1211 is a first segment 122. The inner surface of the first segment 122 is used to stop the portion of the rotating shaft bushing 2 that extends into the first mounting cavity 1211. For example, the inner surface of the first segment 122 can contact and engage with the portion of the rotating shaft bushing 2 that extends into the first mounting cavity 1211, or the inner surface of the first segment 122 can have a clearance fit with the portion of the rotating shaft bushing 2 that extends into the first mounting cavity 1211.

[0054] This allows the first segment 122 to provide a certain limiting effect on the pivot bushing 2, reducing the amount of radial offset of the pivot bushing 2, so that the pivot bushing 2 can rotate stably in the assembly space 121, and the pivot bushing 2 can reliably drive the unlocking cable 6 to open the engine hood locking structure, thereby improving the reliability of the internal opening drive device 100.

[0055] Reference Figure 3 , Figure 5 and Figure 6 According to some embodiments of the present invention, the mounting base 1 is further provided with a first elastic claw 14. The first elastic claw 14 includes a first elastic connecting portion 141 and a first abutting portion 142. The first elastic connecting portion 141 is connected to the end face of the first segment 122 away from the abutting partition 13. The first abutting portion 142 is connected to one end of the first elastic connecting portion 141 away from the abutting partition 13, and the first abutting portion 142 protrudes toward the first mounting cavity 1211. In a first direction, the first abutting portion 142 abuts against the side surface of the flange ring 22 away from the abutting partition 13. For example, there are multiple first elastic claws 14, and the multiple first elastic claws 14 are arranged at circumferential intervals along the first segment 122.

[0056] This allows the first elastic claw 14 and the stop plate 13 to cooperate in limiting the rotating shaft bushing 2 in the first direction, so that the first elastic claw 14, the stop plate 13 and the limiting member 4 form a double limiting structure, so that the rotating shaft bushing 2 is reliably positioned relative to the mounting base 1 in the first direction, reducing the amplitude of the rotating shaft bushing 2 shaking relative to the mounting base 1 in the first direction, ensuring the stability of the rotating shaft bushing 2, and ensuring the stability of the internal opening drive device 100.

[0057] Reference Figure 3 , Figure 5 and Figure 6 According to some embodiments of the present invention, in the direction away from the stop plate 13, the size of the first stop portion 142 in the radial direction of the first segment 122 gradually decreases. That is, in the direction from the outside to the inside of the first mounting cavity 1211, the side surface of the first stop portion 142 away from the stop plate 13 extends obliquely toward the stop plate 13. This can guide the mating sleeve 23, making it easier for the mating sleeve 23 to push open the first elastic claw 14 and insert into the first mounting cavity 1211.

[0058] Reference Figure 6 According to some embodiments of the present invention, an avoidance notch 123 is provided on the mounting sleeve 12. The avoidance notch 123 penetrates the mounting sleeve 12 radially and extends along a first direction. The avoidance notch 123 penetrates the end face of the first segment 122 away from the stop plate 13, and the first elastic connecting portion 141 passes through the avoidance notch 123. This can reduce the overall size of the mounting sleeve 12 and the first elastic claw 14 in the first direction, and reduce the size of the mounting base 1 in the first direction, making the size of the mounting base 1 in the first direction more compact.

[0059] Reference Figure 7 and Figure 8 According to some embodiments of the present invention, the rotating shaft bushing 2 includes: a rotating shaft body 21, a flange ring 22, and a mating sleeve 23. The rotating shaft body 21 extends along a first direction and passes through a through hole 131 into a first mounting cavity 1211 and a second mounting cavity 1212. The flange ring 22 is sleeved on the portion of the rotating shaft body 21 located in the first mounting cavity 1211. The mating sleeve 23 is sleeved on the rotating shaft body 21 and is connected to the side surface of the flange ring 22 facing the stop plate 13. The mating sleeve 23 and the stop plate 13 abut against each other in the first direction. The mating sleeve 23 and the rotating shaft body 21 are radially spaced, and the mating sleeve 23 and the rotating shaft body 21 together define a mounting groove 24. A return torsion spring 3 passes through the mounting groove 24.

[0060] When installing the internal drive device 100, the return torsion spring 3 can be first sleeved on the shaft body 21 and pushed into the mounting groove 24. Then, along the direction from the first mounting cavity 1211 to the second mounting cavity 1212, the shaft body 21 of the shaft bushing 2 is inserted through the through hole 131 into the first mounting cavity 1211 and the second mounting cavity 1212. The mating sleeve 23 is inserted into the first mounting cavity 1211 and abutted against the stop plate 13. Then, the limiting member 4 is connected to the part of the shaft body 21 located in the second mounting cavity 1212. Finally, the combined structure of the mounting base 1, the shaft bushing 2, the return torsion spring 3, and the limiting member 4 is installed on the mounting panel. The mounting panel can be the inner A-pillar panel of the vehicle, or it can be the beam structure of the instrument panel frame.

[0061] By abutting the mating sleeve 23 and the limiting member 4 against the two sides of the abutting partition 13 in the first direction, the mating sleeve 23 and the limiting member 4 cooperate to fix the rotating shaft bushing 2 relative to the mounting base 1, preventing the rotating shaft bushing 2 from falling off the mounting base 1. This makes the rotating shaft bushing 2 and the mounting base 1 reliably fixed, eliminating the need to use the mounting panel to limit the rotating shaft bushing 2. This ensures a reliable connection of the assembly of the mounting base 1, the rotating shaft bushing 2 and the limiting member 4, making it easier for operators to hold and place, reducing the installation difficulty of the internal opening drive device 100, reducing the workload of the workers, and improving the assembly efficiency of the internal opening drive device 100.

[0062] By inserting the reset torsion spring 3 into the mounting groove 24, when the sleeve 23 and the stop plate 13 are engaged, the stop plate 13 can partially seal the opening of the mounting groove 24, preventing the reset torsion spring 3 from coming out of the mounting groove 24. This makes the reset torsion spring 3 reliably positioned relative to the rotating shaft body 21, eliminating the need to use the mounting panel to limit the reset torsion spring 3. This ensures a reliable connection of the assembly of the mounting base 1, rotating shaft bushing 2, reset torsion spring 3 and limiting member 4, making it easier for operators to hold and place, reducing the installation difficulty of the internal opening drive device 100, reducing the workload of the workers, and improving the assembly efficiency of the internal opening drive device 100.

[0063] Reference Figure 3 , Figure 5 , Figure 7 and Figure 8According to some embodiments of the present invention, the portion of the rotating shaft body 21 located in the second mounting cavity 1212 is a locking portion 211. The locking portion 211 defines a limiting groove 212 extending circumferentially along the rotating shaft body 21. A portion of the limiting member 4 passes through the limiting groove 212, that is, the limiting member 4 is engaged with the rotating shaft body 21. For example, the limiting member 4 can be an open snap ring, and the limiting groove 212 is an annular groove formed on the radially outer surface of the locking portion 211. This facilitates the connection and fixation between the limiting member 4 and the rotating shaft body 21, has a simple structure, is easy to use, and can improve the efficiency of connecting the limiting member 4 to the rotating shaft body 21.

[0064] Reference Figure 5 , Figure 8 and Figure 9 According to some embodiments of the present invention, a first flexible member 25 is sandwiched between the mating sleeve 23 and the stop partition 13; for example, the first flexible member 25 can be a fabric member, a sponge member, a leather member, a rubber member, or a silicone member; the first flexible member 25 can be connected to the end face of the mating sleeve 23 facing the stop partition 13 in the axial direction, or the first flexible member 25 can be connected to the surface of the stop partition 13 facing the mating sleeve 23 in the first direction.

[0065] When the drive shaft bushing 2 rotates relative to the mounting base 1, the first flexible element 25 can absorb the vibration between the mating sleeve 23 and the stop plate 13, reducing the noise generated when the mating sleeve 23 rotates relative to the stop plate 13. Moreover, when the mating sleeve 23 presses against the stop plate 13, the first flexible element 25 can generate a certain elastic deformation, allowing the mating sleeve 23 and the stop plate 13 to have a certain dimensional allowance in the first direction. This allows the dimensional accuracy of the mating sleeve 23, the stop plate 13, the limiting groove 212, and the limiting element 4 in the first direction to be set to a lower level, reducing the production difficulty of the mating sleeve 23, the stop plate 13, the limiting groove 212, and the limiting element 4, increasing the pass rate of the mating sleeve 23, the stop plate 13, the limiting groove 212, and the limiting element 4, and reducing the production cost of the mating sleeve 23, the stop plate 13, the limiting groove 212, and the limiting element 4.

[0066] According to some embodiments of the present invention, a second flexible member is sandwiched between the limiting member 4 and the stop partition 13; for example, the second flexible member can be a fabric member, a sponge member, a leather member, a rubber member, or a silicone member; the second flexible member can be connected to the end face of the mating sleeve 23 facing the stop partition 13 in the axial direction, or the second flexible member can be connected to the surface of the stop partition 13 facing the mating sleeve 23 in the second direction.

[0067] When the drive shaft bushing 2 rotates relative to the base, the second flexible element can absorb the vibration between the mating sleeve 23 and the stop plate 13, reducing the noise generated when the mating sleeve 23 rotates relative to the stop plate 13. Moreover, when the mating sleeve 23 presses against the stop plate 13, the second flexible element can generate a certain elastic deformation, allowing the mating sleeve 23 and the stop plate 13 to have a certain dimensional allowance in the second direction. This allows the dimensional accuracy of the mating sleeve 23, the stop plate 13, the limiting groove 212, and the limiting element 4 in the second direction to be set at a lower level, reducing the production difficulty of the mating sleeve 23, the stop plate 13, the limiting groove 212, and the limiting element 4, increasing the pass rate of the mating sleeve 23, the stop plate 13, the limiting groove 212, and the limiting element 4, and reducing the production cost of the mating sleeve 23, the stop plate 13, the limiting groove 212, and the limiting element 4.

[0068] Reference Figure 3 , Figure 5 , Figure 6 and Figure 8 According to some embodiments of the present invention, a first positioning hole 132 is formed on the stop plate 13, the first positioning hole 132 is spaced apart from the through hole 131, the torsion arm connected to the mounting base 1 extends along the first direction, and the torsion arm connected to the mounting base 1 passes through the first positioning hole 132.

[0069] When assembling the drive device 100, the reset torsion spring 3 can be first sleeved on the shaft body 21, and the torsion spring body can be pushed into the mounting groove 24. Then, along the direction from the first mounting cavity 1211 to the second mounting cavity 1212, the shaft body 21 of the shaft bushing 2 can be inserted through the through hole 131 into the first mounting cavity 1211 and the second mounting cavity 1212. The mating sleeve 23 can be inserted into the first mounting cavity 1211 and abutted against the abutment partition 13. The torsion arm connected to the mounting base 1 can be inserted into the first positioning hole 132. Then, the limiting member 4 can be connected to the part of the shaft body 21 located in the second mounting cavity 1212.

[0070] By opening a first positioning hole 132 on the stop plate 13 and setting the torsion arm connected to the mounting base 1 to extend along the first direction and pass through the first positioning hole 132, one of the torsion arms can be connected to the stop plate 13 by inserting it along the first direction. This allows the rotating shaft bushing 2 to drive the reset torsion spring 3 to move in the first direction, thus completing the connection between the torsion arm and the stop plate 13. This facilitates the connection and positioning of the reset torsion spring 3, resulting in a simple structure and convenient assembly.

[0071] Reference Figure 3 , Figure 5 , Figure 6 and Figure 8According to some embodiments of the present invention, a second positioning hole 221 is provided on the flange ring 22, and a torsion arm connected to the rotating shaft bushing 2 extends along the first direction and passes through the second positioning hole 221.

[0072] When assembling the drive device 100, the torsion arm connected to the shaft bushing 2 can be connected to the mounting base 1 first, the shaft hole of the torsion spring body can be aligned with the through hole 131, and then the locking part 211 of the shaft body 21 can be passed through the first mounting cavity 1211, the shaft hole of the torsion spring body, the through hole 131 and the second mounting cavity 1212 in one go along the direction from the first mounting cavity 1211 to the second mounting cavity 1212, and the torsion spring body can be fitted into the mounting groove 24. After that, the limiting member 4 can be connected to the part of the shaft body 21 located in the second mounting cavity 1212.

[0073] By setting the torsion arm of the reset torsion spring 3 to extend along the first direction, the torsion arm connected to the rotating shaft bushing 2 can be connected to the flange ring 22 by inserting and engaging in the first direction. This allows the rotating shaft bushing 2 to move only relative to the reset torsion spring 3 in the first direction to complete the connection between the torsion arm and the flange ring 22, which facilitates the connection and positioning of the reset torsion spring 3. The structure is simple and the assembly is convenient.

[0074] For example, refer to Figure 3 , Figure 5 , Figure 6 and Figure 8 According to some embodiments of the present invention, both torsion arms extend along a first direction, a first positioning hole 132 is provided on the stop plate 13, the first positioning hole 132 is spaced apart from the through hole 131, a second positioning hole 221 is provided on the flange ring 22, both torsion arms extend along the first direction, and the two torsion arms are respectively inserted into the first positioning hole 132 and the second positioning hole 221.

[0075] When assembling the drive device 100, the reset torsion spring 3 can be first sleeved on the shaft body 21, one of the torsion arms can be inserted into the second positioning hole 221, and the torsion spring body can be pushed into the mounting groove 24. Then, along the direction from the first mounting cavity 1211 to the second mounting cavity 1212, the shaft body 21 of the shaft bushing 2 can be inserted into the first mounting cavity 1211 and the second mounting cavity 1212 through the through hole 131. The mating sleeve 23 can be inserted into the first mounting cavity 1211 and abutted against the abutment partition 13. The other torsion spring can be inserted into the first positioning hole 132. Then, the limiting member 4 can be connected to the part of the shaft body 21 located in the second mounting cavity 1212.

[0076] When assembling the drive device 100, one of the torsion arms of the reset torsion spring 3 can be inserted into the first positioning hole 132, and the shaft hole of the torsion spring body can be aligned with the through hole 131. Then, along the direction from the first mounting cavity 1211 to the second mounting cavity 1212, the locking part 211 of the rotating shaft body 21 is passed through the first mounting cavity 1211, the shaft hole of the torsion spring body, the through hole 131 and the second mounting cavity 1212 in one go. The torsion spring body is then fitted into the mounting groove 24, and the other torsion arm is inserted into the second positioning hole 221. After that, the limiting member 4 is connected to the part of the rotating shaft body 21 located in the second mounting cavity 1212.

[0077] By setting the torsion arm of the reset torsion spring 3 to extend along the first direction, one torsion arm can be connected to the stop plate 13 by inserting it along the first direction, and the other torsion arm can be connected to the flange ring 22 by inserting it along the first direction. The rotating shaft bushing 2 can move only relative to the reset torsion spring 3 in the first direction to complete the connection between the torsion arm and the flange ring 22. The rotating shaft bushing 2 drives the reset torsion spring 3 to move in the first direction to complete the connection between the torsion arm and the stop plate 13. The structure is simple and the assembly is convenient.

[0078] Reference Figures 1-4 According to some embodiments of the present invention, the internal opening drive device 100 further includes an opening handle 5, which includes a latching arm 51 and a handle connecting shaft 52. The handle connecting shaft 52 extends along a first direction and is connected to the portion of the rotating bushing 2 facing away from the second mounting cavity 1212. The latching arm 51 is connected to the end of the handle connecting shaft 52 facing away from the second mounting cavity 1212. When it is necessary to open the hood locking structure, a force can be applied to the latching arm 51 away from the handle connecting shaft 52 to drive the handle connecting shaft 52 and the rotating bushing 2 to rotate, thereby driving the unlocking cable 6 to open the hood locking structure. This allows the user to drive the rotating bushing 2 to rotate with less effort, improving the overall performance of the internal opening drive device 100.

[0079] Reference Figures 1-4According to some embodiments of the present invention, the lever cantilever 51 abuts against the rotating shaft bushing 2 in a first direction; the handle connecting shaft 52 has a first rotation limiting structure and a first limiting structure, and the portion of the rotating shaft bushing 2 facing away from the second mounting cavity 1212 has a second rotation limiting structure 214 and a second limiting structure. The first rotation limiting structure and the second rotation limiting structure 214 are inserted into each other in the first direction to limit the handle connecting shaft 52 in the circumferential direction of the rotating shaft bushing 2. The side surface of the first limiting structure facing away from the abutting partition 13 abuts against the side surface of the second limiting structure facing the abutting partition 13. For example, the first rotation limiting structure and the second rotation limiting structure 214 can be keyway structures that cooperate with each other and have a non-circular cross-section, and multiple sets of the first rotation limiting structure and the second rotation limiting structure 214 can also cooperate with each other.

[0080] By limiting the handle connecting shaft 52 in the circumferential direction of the rotating shaft bushing 2 through the first rotation limiting structure and the second rotation limiting structure 214, the unlocking method of driving the rotating shaft bushing 2 to rotate by pulling the cantilever arm 51 can be realized in a relatively reliable manner. The structure is simple and easy to use.

[0081] By setting the lever arm 51 and the pivot bushing 2 as a stop in the first direction, and setting the side surface of the first limiting structure away from the stop plate 13 and the side surface of the second limiting structure facing the stop plate 13 as a stop, the pivot bushing 2 can be positioned in the first direction, reducing the amplitude of the audible shaking of the handle shaft 52 relative to the pivot bushing 2 in the first direction, ensuring the stability of the handle shaft 52, ensuring the stability of the opening handle 5, and improving the overall performance of the internal opening drive device 100.

[0082] Reference Figures 1-4 According to some embodiments of the present invention, the handle connecting shaft 52 includes a plug-in portion 521, which is connected to the buckle cantilever 51. The first rotation limiting structure is a spline tooth provided on the radial outer peripheral surface of the plug-in portion 521. The rotating shaft bushing 2 defines a plug-in hole 213. The second rotation limiting structure 214 is a spline groove provided on the radial inner peripheral surface of the plug-in hole 213. The plug-in portion 521 is inserted into the plug-in hole 213, and the first rotation limiting structure passes through the second rotation limiting structure 214.

[0083] By setting the first rotation limiting structure and the second rotation limiting structure 214 as a keyway insertion structure, and setting the first rotation limiting structure on the radial outer circumferential surface of the insertion part 521 of the main body, and setting the second rotation limiting structure 214 on the radial inner circumferential surface of the insertion hole 213, the handle connecting shaft 52 can be inserted into the insertion hole 213, reducing the overall size of the rotating shaft bushing 2 and the handle connecting shaft 52 in the first direction, so that the space occupied by the rotating shaft bushing 2 and the handle connecting shaft 52 in the first direction is smaller, and the space occupied by the inner opening drive device 100 in the first direction is smaller, which can effectively solve the problem of limited installation space of the inner opening drive device 100 in the vehicle.

[0084] Reference Figures 1-4 According to some embodiments of the present invention, the handle connecting shaft 52 includes a limiting link 522 and a limiting connector 523. One end of the limiting link 522 is connected to the end face of the insertion part 521 away from the buckle cantilever 51, and the other end is connected to the limiting connector 523. The limiting connector 523 protrudes radially from the limiting link 522, and the limiting connector 523 and the insertion part 521 define a snap-fit ​​groove 524. The first limiting structure may include the limiting link 522 and the limiting connector 523.

[0085] The rotating bushing 2 also includes a second elastic claw 26, which includes a second elastic connecting portion 261 and a second stop portion 262. The second elastic connecting portion 261 is connected to the axial surface of the insertion hole 213 facing the buckle cantilever 51, and the second stop portion 262 is connected to the end of the second elastic connecting portion 261 away from the stop plate 13, and the second stop portion 262 protrudes into the locking groove 524, and the second stop portion 262 abuts against the limiting joint 523 in a first direction. For example, the second limiting structure can be the second elastic claw 26. Specifically, there can be multiple second elastic claws 26, which are arranged in a ring, and the second stop portion 262 extends into the annular groove defined by the multiple elastic claws. The limiting structure is inserted into the annular groove.

[0086] By adapting the second elastic claw 26 to the limiting structure and placing the second elastic claw 26 inside the insertion hole 213, and placing the limiting connecting rod 522 and the limiting connector 523 at the end of the insertion part 521 away from the buckle cantilever 51, a stop-locking engagement between the first limiting structure and the second limiting structure can be achieved. At the same time, the first limiting structure and the second limiting structure can be hidden in the insertion hole 213, so that the limiting engagement between the insertion part 521 and the insertion hole 213 can limit the handle connecting shaft 52 in the circumferential direction. This allows the second stop 262 to reliably protrude into the locking groove 524 and maintain a reliable abutment relationship with the limiting structure, effectively reducing the risk of the handle connecting shaft 52 falling out of the insertion hole 213 due to misalignment of the second stop 262 and the limiting structure, and improving the reliability of the internal opening drive device 100.

[0087] Reference Figure 4 , Figure 7 and Figure 8 According to some embodiments of the present invention, the rotating shaft bushing 2 further includes a pull wire fixing block 27, which is connected to the radial outer surface of the mating sleeve 23. For example, the pull wire fixing block 27 is used to connect the unlocking pull wire 6. This prevents the pull wire fixing block 27 from interfering with the opening handle 5, and allows the pull wire fixing block 27 to be close to the stop plate 13. This reduces the torque exerted by the unlocking pull wire 6 on the rotating shaft bushing 2 through the pull wire block, thereby reducing the risk of the rotating shaft bushing 2 tilting radially due to force. This allows the rotating shaft bushing 2 to reliably rotate within the assembly space 121, improving the stability of the internal opening drive device 100.

[0088] A vehicle according to a second aspect embodiment of the present invention includes: an internal opening drive device 100 according to the first aspect embodiment described above. For example, the vehicle may be an automobile.

[0089] According to the present invention, the vehicle can reliably connect the assembly of the mounting base 1, the rotating shaft bushing 2, the reset torsion spring 3 and the limiting member 4 after assembly by the aforementioned internal opening drive device 100, making it easy for operators to hold and place, reducing the installation difficulty of the internal opening drive device 100, reducing the workload of the operators, improving the assembly efficiency of the internal opening drive device 100, and improving the production efficiency of the vehicle.
