Description

Technical Field

[0001] This application relates to flip-top assemblies, and more particularly to flip-top assemblies for fuel filler caps or charging ports in vehicles. Background Technology

[0002] A refueling or charging port flip cover is used to open and close the vehicle's refueling or charging port. The flip cover is rotatably mounted on the vehicle body. When refueling or charging is not needed, the flip cover is locked in the closed position by a locking device. When refueling or charging is needed, the locking device releases the flip cover, which then moves from the closed position to the open position. Therefore, an actuation component is required to control the movement of the flip cover and the locking device. Summary of the Invention

[0003] The purpose of this application is to at least partially satisfy the above-mentioned technical requirements. According to a first aspect of this application, an actuation assembly is provided for actuating a flip cover rotatably mounted on a base, comprising a locking device, a flip cover pivot, a transmission gear, a drive gear, and a drive member. The locking device is movably disposed on the base and configured to lock or release the flip cover. The flip cover pivot is configured to drive the flip cover to rotate and includes an assembly portion. The transmission gear includes a receiving portion, which is sleeved on the assembly portion of the flip cover pivot via the receiving portion. The drive gear and the drive member are configured to rotate synchronously driven by a common power source, the drive gear meshing with the transmission gear, and the drive member is configured to drive the locking device to move. The assembly part and the receiving part are provided with a joining structure. The joining structure is configured to allow the receiving part and the assembly part to be rotatably engaged or rotatably disengaged. When the receiving part and the assembly part are rotatably engaged, the drive gear can drive the flip cover to rotate through the transmission gear and the flip cover shaft. When the receiving part and the assembly part are rotatably disengaged, the transmission gear can rotate relative to the flip cover shaft.

[0004] According to the aforementioned actuation assembly, the locking device has a locked position and a released position. The locking device is configured to lock the flip cover when it is in the locked position and to release the flip cover when it is in the released position. The engagement structure is configured such that, during the movement of the locking device from the locked position to the released position, the receiving portion rotates apart from the mounting portion, causing the transmission gear to rotate relative to the flip cover's pivot shaft. The locking device is in the released position when the receiving portion rotates into engagement with the mounting portion to drive the flip cover's pivot shaft to open the flip cover via the transmission gear.

[0005] According to the aforementioned actuation assembly, the engagement structure includes a protrusion disposed on the flip-top pivot and a protrusion cavity disposed on the transmission gear, the protrusion extending outward from the outer periphery of the flip-top pivot. In the rotational direction of the flip-top pivot, the size of the protrusion cavity is larger than the size of the protrusion.

[0006] According to the aforementioned actuation assembly, the transmission gear is sector-shaped, and the outer circumference of the sector is toothed to mesh with the drive gear. The toothed portion surrounds the receiving part.

[0007] According to the aforementioned actuation assembly, the central angle of the toothed portion of the outer circumference of the transmission gear is greater than the maximum angle at which the flip cover can be opened.

[0008] According to the aforementioned actuation assembly, the drive gear includes external teeth arranged around the entire outer circumference of the drive gear.

[0009] According to the aforementioned actuation components, the drive device further includes a drive shaft, and the drive gear, the drive member, and the drive shaft are connected together. The drive gear and the drive member are capable of rotating as the drive shaft rotates. The drive shaft is driven by a common power source.

[0010] According to the aforementioned actuation assembly, the drive element includes a drive arm rotatable about the drive shaft. The drive arm and the locking device are configured such that the drive arm can actuate the locking device from the locked position to the released position.

[0011] According to a second aspect of this application, a flip-top assembly for a fuel filler or charging port is provided, comprising a base, a flip-top, and an actuation component according to a first aspect of this application. The flip-top is rotatably mounted on the base. The actuation component is disposed on the base.

[0012] According to the aforementioned flip-top assembly for the fuel filler or charging port, the base is provided with a through hole, and the flip-top is provided with a locking receiving part. The locking device can pass through the through hole and the locking receiving part, thereby locking the flip-top.

[0013] The actuation component of this application enables the drive gear to prevent the transmission gear from rotating and open the flip cover when the flip cover is in the closed position and the locking device moves from the released position to the locked position.

[0036] Various specific embodiments of this application will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that although terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "top," and "bottom," are used herein to describe various exemplary structural parts and elements, their use is merely for illustrative purposes and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed herein can be arranged in different orientations, these terms indicating direction are illustrative only and should not be considered limiting.

[0037] Figure 1A This is a perspective view from the front of an embodiment of the fuel filler or charging port flip cover assembly 100 of this application, wherein the flip cover 190 is in a closed state; Figure 1B yes Figure 1A The image shows a front-view perspective view of the fuel filler or charging port flip cover assembly 100, with the flip cover 190 in the open position. Figure 1C yes Figure 1A A perspective view of the fuel filler or charging port flip cover assembly 100 as shown from below; Figure 1D yes Figure 1A An exploded view of the front of the fuel filler or charging port flip-top assembly 100 shown. Figure 1E yes Figure 1A The exploded view of the fuel filler or charging port flip cover assembly 100 shown is from the rear side. For ease of illustration and explanation, the base 101 is shown in... Figure 1A The right side shown is defined as the right side, and the opposite side is defined as the left side. The base 101 is placed in... Figure 1A The front side is defined as the front side, and the side opposite to the front side is defined as the rear side.

[0038] like Figure 1A-1E As shown, the fuel filler or charging port flip cover assembly 100 includes a base 101, a flip cover 190, and an actuation assembly. The actuation assembly includes a hinge 170, a flip cover pivot 176, a transmission gear 132, a drive unit 140, a power source 150, a locking device 120, and a resilient member 160. The hinge 170, flip cover pivot 176, transmission gear 132, drive unit 140, power source 150, locking device 120, and resilient member 160 are mounted on the base 101. Specifically, the base 101 has a cavity 105. The flip cover 190 includes a flip cover body 110 and a connecting portion 112. The flip cover body 110 covers the connecting portion 112. The connecting portion 112 is connected to the hinge 170. The right end of the hinge 170 is rotatably mounted on the base 101 via the flip cover pivot 176, thereby allowing the flip cover 190 to rotate relative to the base 101. The connecting part 112 is provided with a flip-top hole 111.

[0039] A transmission gear 132 is fitted onto the flip cover shaft 176. The flip cover 190 has a closed position and an open position. When the flip cover 190 is in the closed position, it covers the top of the cavity 105 to seal it. When the flip cover 190 is in the open position, the cavity 105 is exposed to accommodate external components for refueling or charging. A locking device 120 is mounted on the front side of the base 101 and configured to lock and release the hinge 170, thereby locking and releasing the flip cover 190. The locking device 120 has a locked position and a released position. When the locking device 120 is in the locked position, it passes through a through hole 222 on the base 101 (see...). Figure 2BThe locking device 120 extends into the flap hole 111 on the hinge 170. When the locking device 120 is in the released position, the locking device 120 disengages from the flap hole 111 on the hinge 170, thereby allowing the flap 190 to rotate relative to the base 101. A power source 150 is mounted on the lower front side of the base 101 and is configured to provide driving force to drive the flap 190 to open and close, and to provide driving force to drive the locking device 120 to lock and release. As an example, the power source 150 is an electric motor. A drive unit 140 is mounted on the front side of the base 101 and is generally located behind the power source 150. The drive unit 140 is configured to be driven to rotate by the power source 150. The rotation of the drive unit 140 can drive the locking device 120 and the transmission gear 132 to move. An elastic member 160 is mounted below the base 101 to provide force for the movement of the locking device 120 from the released position to the locked position. As an example, the elastic member 160 is a spring.

[0040] Figure 2A Is it like this? Figure 1A-1E A perspective view of the base 101 as shown from above; Figure 2B Is it like this? Figure 1A-1E The perspective view of the base 101 shown below is used to illustrate the specific structure of the base 101 more clearly. For example... Figure 2A-2B As shown, the base 101 includes a housing 210 forming a cavity 105 and a mounting portion 220. The mounting portion 220 is connected to the housing 210 and is located at the right end of the base 101. The base 101 can be mounted on the vehicle body via the mounting portion 220. The cavity 105 of the housing 210 is open at both the top and bottom, so that after the flip-top assembly 100 is mounted on the vehicle body, the cavity 105 communicates with the vehicle's fuel tank opening or charging port. In this way, external components for refueling or charging can extend into the vehicle's fuel tank opening or charging port through the cavity 105. The mounting portion 220 of the base 101 has a cavity (not shown) communicating with the cavity 105 of the housing 210 for accommodating a portion of the hinge 170.

[0041] The top of the housing 210 of the base 101 has an outwardly folded flange 219. A through hole 222 is provided on the side wall of the housing 210. The through hole 222 is located at the left end of the base 101 and near the front. The through hole 222 is configured to receive a locking pin 128 on the locking device 120 (see...). Figure 1D-1E ).

[0042] The lower front portion of the base 101 is provided with protrusions 231 and 232. Protrusions 231 and 232 extend downwards and forwards from the bottom of the base 101, forming recesses 241 and 242 respectively between the protrusions 231 and 232 and the base 101, for accommodating the locking device 120 and guiding its movement in the left-right direction. One end of the elastic member 160 is connected to the protrusion 231, thereby connecting the elastic member 160 to the base 101.

[0043] The front side of the base 101 has a power source mounting plate 216, a flip cover hinge mounting hole 217, and a drive device mounting part 218 at the mounting part 220. The flip cover hinge mounting hole 217 and the drive device mounting part 218 extend through the base 101 in the front-rear direction. The power source 150 is mounted on the power source mounting plate 216. The flip cover hinge mounting hole 217 is used to accommodate the flip cover hinge 176, and the drive device mounting part 218 is used to accommodate the drive device 140.

[0044] Figure 3 for Figure 1A-1E The diagram shows a perspective view from the front of the connection portion 112 between the hinge 170 and the flip cover 190, illustrating the specific structure of the connection portion 112. (See diagram below.) Figure 3As shown, the hinge 170 and the connecting portion 112 of the flip cover 190 are integrally formed. The hinge 170 is connected to the right side of the connecting portion 112. The connecting portion 112 is used to connect with the flip cover body 110. Specifically, the top of the connecting portion 112 is provided with a hinge engaging portion 310, and the bottom of the flip cover body 110 is provided with a corresponding flip cover engaging portion (not shown). The hinge engaging portion 310 can cooperate with the flip cover engaging portion to connect the connecting portion 112 and the flip cover body 110 together. The lower side of the left end of the connecting portion 112 is provided with a flip cover hole 111 to form a locking receiving portion. When the locking device 120 passes through the through hole 222 on the base 101 and the flip cover hole 111 (i.e., the locking receiving portion) on the connecting portion 112 of the flip cover 190, the locking device 120 can lock the flip cover 190 and the hinge 170. When the locking device 120 disengages from the flip cover hole 111, the locking device 120 releases the hinge 170 of the flip cover 190, allowing the flip cover 190 to be opened. The hinge 170 is generally bent and includes a hinge pivot 304 at its end. The hinge pivot 304 is generally cylindrical and is received in a flip cover pivot mounting hole 217 in the base 101, allowing the hinge 170 to rotate relative to the base 101. The hinge pivot 304 is provided with a flip cover pivot receiving portion 311. The flip cover pivot receiving portion 311 is generally cylindrical and extends in the front-rear direction. A radial receiving portion 312 is also provided circumferentially at the front end of the flip cover pivot receiving portion 311, extending radially. The flip cover pivot receiving portion 311 is used to cooperate with the flip cover pivot 176, thereby allowing the flip cover pivot 176 to be connected to the hinge 170.

[0045] The following is for reference. Figure 1D-1E To describe the specific structure of the locking device 120. For example... Figure 1D-1EAs shown, the locking device 120 includes a locking lever 121, a locking part 127, a pushing part 123, a guide part 124, a guide part 125, and a protrusion 126. The locking lever 121 is elongated and extends a certain length in the left-right direction. The locking part 127 is located at the left end of the locking lever 121 and is generally hook-shaped, extending rearward. One end of the locking part 127 is connected to the locking lever 121, and the other end forms a locking pin 128. The locking pin 128 can extend into and retract from the through hole 222 on the base 101 and the flip-cover hole 111 on the hinge 170, thereby locking the flip-cover 190 to the base 101 or releasing the flip-cover 190 from the base 101. The pushing part 123 is located at the right end of the locking lever 121 and is generally plate-shaped. The pushing part 123 is arranged vertically and connected to the locking lever 121. The pushing part 123 is used to cooperate with the drive device 140. When the drive device 140 pushes the push part 123, the drive device 140 can move the locking device 120. Guide parts 124 and 125 are provided on the rear side of the locking bar 121, and are spaced a certain distance apart. Guide parts 124 and 125 can respectively cooperate with protrusions 232 and 231 on the base 101, thereby guiding the locking device 120 to move in the left-right direction. Protrusion 126 is provided on the rear side of the locking bar 121, and is positioned between guide parts 125 and locking part 127. One end of the elastic member 160 is connected to the protrusion 126, and the other end of the elastic member 160 is connected to the base 101.

[0046] Figure 4A Is it like this? Figure 1A-1E The perspective view shown illustrates the flip-top pivot 176 and the transmission gear 132, illustrating their specific structures. (See attached image.) Figure 4AAs shown, the flip hinge 176 includes a hinge body 401, a protrusion 402, and a cover 403. Specifically, the hinge body 401 is generally cylindrical and can mate with the flip hinge receiving portion 311, being housed within it. A radial protrusion 404 is provided circumferentially at the center of the hinge body 401, extending radially outward along the hinge body 401. The radial protrusion 404 can match the radial receiving portion 312 on the hinge 170, thereby connecting the flip hinge 176 to the hinge 170. A protrusion 402 is provided at the front end of the hinge body 401. The protrusion 402 extends radially outward along the outer periphery of the flip hinge 176. More specifically, the protrusion 402 includes an upper protrusion 411 and a lower protrusion 412. The left and right sides of the upper protrusion 411 and the left and right sides of the lower protrusion 412 are both planar. The left side of the upper protrusion 411 and the left side of the lower protrusion 412 form an obtuse angle, and the right side of the upper protrusion 411 and the right side of the lower protrusion 412 also form an obtuse angle, so as to cooperate with the transmission gear 132. The cover 403 is provided at the front end of the rotating shaft body 401, and the circumferential dimension of the cover 403 is larger than the circumferential dimension of the rotating shaft body 401, so as to prevent the transmission gear 132 from dislodging from the front end of the rotating shaft body 401 after it is sleeved on the rotating shaft body 401.

[0047] like Figure 4A As shown, the transmission gear 132 has sector-shaped teeth. Specifically, it has a protruding cavity 421 in its middle. The protruding cavity 421 extends through the transmission gear 132 in the front-to-back direction. The opposite left and right sides of the protruding cavity 421 are flat, while the opposite top and bottom sides are arc-shaped. The size of the protruding cavity 421 is larger than the size of the protrusion 402, so that the protrusion 402 can be accommodated in the protruding cavity 421. The outer circumference of the sector-shaped transmission gear 132 is a toothed portion 422, which can mesh with the drive gear 504. The toothed portion 422 is arranged around the protruding cavity 421. The central angle of the toothed portion 422 on the outer circumference of the transmission gear 132 is greater than the maximum angle at which the flip cover 190 can be opened.

[0048] Figure 4B Is it like this? Figure 1A-1E The diagram shows a cross-sectional view of the fit between the flip-top pivot 176 and the transmission gear 132, illustrating the fit between the protrusion 402 on the flip-top pivot 176 and the protrusion cavity 421 on the transmission gear 132. Figure 4B As shown, the protrusion 402 is accommodated in the protrusion cavity 421. Figure 4BIn the shown state, the left side of the upper protrusion 411 abuts against the left wall of the protrusion cavity 421, and the right side of the lower protrusion 412 abuts against the right wall of the protrusion cavity 421. However, the right side of the upper protrusion 411 does not abut against the right wall of the protrusion cavity 421, and the left side of the lower protrusion 412 does not abut against the left wall of the protrusion cavity 421. If the transmission gear 132 rotates counterclockwise at this time, since the left side of the upper protrusion 411 abuts against the left wall of the protrusion cavity 421 and the right side of the lower protrusion 412 abuts against the right wall of the protrusion cavity 421, the transmission gear 132 can drive the flip cover shaft 176 to rotate counterclockwise. However, if the transmission gear 132 rotates clockwise at this time, since the right side of the upper protrusion 411 does not abut against the right side wall of the protrusion cavity 421 and the left side of the lower protrusion 412 does not abut against the left side wall of the protrusion cavity 421, the transmission gear 132 will not drive the flip cover shaft 176 to rotate. Instead, it will rotate relative to the flip cover shaft 176 until the right side of the upper protrusion 411 abuts against the right side wall of the protrusion cavity 421 and the left side of the lower protrusion 412 abuts against the left side wall of the protrusion cavity 421. Only then can the transmission gear 132 drive the flip cover shaft 176 to rotate.

[0049] The protrusion 402 and the protrusion cavity 421 are respectively called the assembly part and the receiving part. The transmission gear 132 is sleeved on the assembly part of the flip cover shaft 176 through the receiving part. The protrusion (assembly part) 402 and the protrusion cavity (receiving part) 421 can form a joint structure so that the assembly part and the receiving part can be rotatably engaged or rotatably disengaged. When the receiving part and the assembly part are rotatably engaged, the transmission gear 132 can drive the flip cover shaft 176 to rotate. And when the receiving part and the assembly part are rotatably disengaged, the transmission gear 132 can rotate relative to the flip cover shaft 176.

[0050] Figure 5A Is it like this? Figure 1A-1E A perspective view of the drive unit 140 from the front side; Figure 5B Is it like this? Figure 1A-1E The perspective view of the drive unit 140 shown from the rear is used to illustrate the specific structure of the drive unit 140 more clearly. (See diagram below.) Figures 5A-5B As shown, the drive device 140 includes a drive shaft 501, a drive member 502, a drive gear 504, and a mounting shaft 506. The drive shaft 501, drive member 502, drive gear 504, and mounting shaft 506 are connected sequentially, and the drive shaft 501 and mounting shaft 506 are coaxially arranged. Specifically, the drive member 502 is generally a disc, on which a drive arm 503 is provided for contacting the pushing part 123 of the locking device 120 (see...). Figure 1D-1EThe drive gear 504 is an external gear with external teeth 505. The external teeth 505 surround the entire outer circumference of the drive gear 504. The external teeth 505 can mesh with the toothed portion 422 of the transmission gear 132. The drive shaft 501 is connected to the output portion (not shown) of the power source 150 so that the power source 150 can drive the drive shaft 501 to rotate when started. In the embodiments of this application, the power source 150 can drive the drive shaft 501 to rotate in both clockwise and counterclockwise directions, therefore the drive device 140 can also rotate in both clockwise and counterclockwise directions under the drive of the power source 150. The mounting shaft 506 can be accommodated in the drive device mounting portion 218 of the base 101 (see...). Figure 2A In this way, the drive unit 140 is mounted on the base 101.

The locking pin 128 of the locking device 120 is inserted into the through hole 222 of the base 101 and the flip hole 111 on the hinge 170, thereby holding the flip cover 190 in the closed position. At this time, the right side of the upper protrusion 411 of the protrusion 402 of the flip cover pivot 176 abuts against the right side wall of the protrusion cavity 421, and the left side of the lower protrusion 412 of the protrusion 402 abuts against the left side wall of the protrusion cavity 421.

[0054] Figures 6A to 6B The process illustrates the unlocking process of the locking device 120. During this process, the power source 150 drives the drive device 140 to rotate counterclockwise, thus the drive member 502 and the drive gear 504 also rotate counterclockwise. On one hand, as the drive member 502 rotates counterclockwise, the drive arm 503 of the drive member 502 abuts against and pushes the push portion 123 of the locking device 120, thereby driving the locking device 120 to move from the locked position to the released position. On the other hand, as the drive gear 504 rotates counterclockwise, since the drive gear 504 meshes with the toothed portion 422 of the transmission gear 132, the transmission gear 132 rotates clockwise. However, during the rotation of the transmission gear 132, the transmission gear 132 rotates relative to the protrusion 402 of the flip cover shaft 176 until the left side of the upper protrusion 411 of the protrusion 402 abuts against the left side wall of the protrusion cavity 421, and the right side of the lower protrusion 412 of the protrusion 402 abuts against the right side wall of the protrusion cavity 421. Thus, in Figures 6B to 6C During the process, the locking device 120 moves from the locked position to the released position, and because the transmission gear 132 rotates relative to the protrusion 402 of the flip cover shaft 176, the flip cover shaft 176 does not move, and the flip cover 190 is in the closed position.

[0055] Figures 6B to 6DThe process illustrates the movement of the flip cover 190 from the closed position to the open position. During this process, the power source 150 continues to drive the drive unit 140 to rotate counterclockwise, thus the drive member 502 and the drive gear 504 also continue to rotate counterclockwise. As the drive gear 504 rotates counterclockwise, since the drive gear 504 meshes with the toothed portion 422 of the transmission gear 132, the left side of the upper protrusion 411 of the protrusion 402 of the flip cover shaft 176 abuts against the left side wall of the protrusion cavity 421, and the right side of the lower protrusion 412 of the protrusion 402 abuts against the right side wall of the protrusion cavity 421. Therefore, the transmission gear 132 rotates clockwise, and the rotation of the transmission gear 132 drives the protrusion 402 of the flip cover shaft 176 to rotate clockwise. The clockwise rotation of the protrusion 402 drives the flip cover 190 to rotate clockwise, thereby moving the flip cover 190 from the closed position to the open position.

[0056] It should be noted that, in Figures 6B to 6C During the process shown, the drive arm 503 of the drive member 502 also rotates clockwise, so the drive arm 503 continues to push the push part 123 of the locking device 120, so that the locking device 120 remains in the unlocked position. Figure 6C In the shown state, the drive arm 503 of the drive member 502 is separated from the push part 123 of the locking device 120. That is, the drive arm 503 of the drive member 502 no longer pushes the push part 123 of the locking device 120. Because in Figures 6A to 6C During the process shown, the locking device 120 continuously moves to the left, thus continuously compressing the spring 425. Until... Figure 6C In the shown state, the drive arm 503 of the drive member 502 is separated from the push part 123 of the locking device 120. At this time, the spring 425 applies a rightward force to the locking device 120, causing the locking device 120 to move to the right until it returns to the locked position. However, since the flip cover 190 is already open, the locking device 120 returning to the locked position does not restrict the movement of the flip cover 190.

[0057] Figures 6D to 6EThe process illustrates the rotation of the protrusion 402 of the flip hinge 176 relative to the transmission gear 132. During this process, the power source 150 drives the drive unit 140 to rotate clockwise, thus the drive member 502 and the drive gear 504 also rotate clockwise. Since the drive gear 504 meshes with the toothed portion 422 of the transmission gear 132, the transmission gear 132 rotates counterclockwise. However, during the rotation of the transmission gear 132, it rotates relative to the protrusion 402 of the flip hinge 176 until the right side of the upper protrusion 411 of the protrusion 402 abuts against the right side wall of the protrusion cavity 421, and the left side of the lower protrusion 412 of the protrusion 402 abuts against the left side wall of the protrusion cavity 421. Thus, in Figures 6C to 6D During the process, the flip cover 190 remains in the open position.

[0058] Figure 6E-6H The process of closing and locking the flip cover 190 is shown:

[0059] Figures 6E to 6G The process illustrates the movement of the flip cover 190 from the open position to the closed position. During this process, the power source 150 continues to drive the drive unit 140 to rotate clockwise, thus the drive member 502 and the drive gear 504 also continue to rotate clockwise. As the drive gear 504 rotates clockwise, since the drive gear 504 meshes with the toothed portion 422 of the transmission gear 132, the right side of the upper protrusion 411 of the protrusion 402 of the flip cover shaft 176 abuts against the right side wall of the protrusion cavity 421, and the left side of the lower protrusion 412 of the protrusion 402 abuts against the left side wall of the protrusion cavity 421. Therefore, the transmission gear 132 rotates counterclockwise, and the rotation of the transmission gear 132 drives the protrusion 402 of the flip cover shaft 176 to rotate counterclockwise. The counterclockwise rotation of the protrusion 402 drives the flip cover 190 to rotate counterclockwise, thereby moving the flip cover 190 from the open position to the closed position.

[0060] It should be noted that, in Figures 6E to 6G During the process shown, the drive arm 503 of the drive component 502 also rotates clockwise. Figures 6E to 6F During the process shown, the drive arm 503 of the drive member 502 remains separated from the push part 123 of the locking device 120 until... Figure 6F In the indicated state, the drive arm 503 of the drive member 502 contacts the push part 123 of the locking device 120. Figures 6F to 6G During the process shown, the drive arm 503 pushes the push part 123 of the locking device 120 so that the locking device 120 moves from the locked position to the unlocked position.

[0061] exist Figures 6G to 6HDuring the process shown, the drive arm 503 of the drive member 502 continues to rotate clockwise, so the drive arm 503 continues to push the push part 123 of the locking device 120, so that the locking device 120 moves from the unlocked position to the locked position, thereby inserting the locking pin 128 of the locking device 120 into the through hole 222 of the base 101 and the flip hole 111 on the hinge 170, so as to keep the flip cover 190 in the closed position.

[0062] Although this application uses protrusion 402 and protrusion cavity 421 as examples to illustrate the assembly part and receiving part, those skilled in the art will understand that the assembly part and receiving part included in the joining structure can be formed by different specific structures, as long as they are configured such that the receiving part and the assembly part can be rotatably engaged or rotatably disengaged. When the receiving part and the assembly part are rotatably engaged, the drive gear 504 can drive the flip cover 190 to rotate through the transmission gear 132 and the flip cover shaft 176. When the receiving part and the assembly part are rotatably disengaged, the transmission gear 132 can rotate relative to the flip cover shaft 176.

[0063] In the prior art, when the flip cover is in the closed position, the transmission gear is no longer restricted by the drive gear, and the drive gear only controls the movement of the locking device. Therefore, when the vehicle is subjected to vibration, the flip cover cannot remain in the closed position, and the locking device cannot lock the flip cover that is not in the closed position.

[0064] Conversely, in the actuation assembly of this application, the transmission gear 132 is always engaged with the drive gear 504. Therefore, when the locking device 120 moves from the release position to the locking position, the transmission gear 132 is always restricted from rotation by the drive gear 504, regardless of whether the vehicle is subjected to vibration. Thus, the flip cover remains in the closed position during the movement of the locking device 120 from the release position to the locking position.

[0065] This specification uses examples to disclose this application, one or more of which are illustrated in the accompanying drawings. Each example is provided for the purpose of explaining this application and not for limiting it. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made to this application without departing from the scope or spirit of this application. For example, features illustrated or described as part of one embodiment may be used with another embodiment to obtain further embodiments. Therefore, it is intended that this application cover modifications and variations made within the scope of the appended claims and their equivalents.
