A flap structure and a motorized device

Abstract

The application provides a cover structure and a motorized device. The cover structure comprises a first cover body, which covers a refueling port to seal the refueling port. In addition, the cover structure can further comprise a rotating device and a lifting device. The rotating device is connected to the first cover body and comprises a first end portion and a second end portion arranged at two ends. In addition, the rotating device is provided with a spiral sliding groove along the direction from the first end portion to the second end portion. The lifting device is partially arranged in the spiral sliding groove. It can be understood that when the lifting device slides in the spiral sliding groove, the lifting device can slide up and down along the direction from the first end portion to the second end portion to drive the rotating device to rotate, so that the first cover body can be displaced relative to the refueling port, thereby realizing the opening of the refueling port. In addition, when the first cover body covers the refueling port, the extension direction of the part of the spiral sliding groove matched with the lifting device is parallel to the axis of the rotating device, so that the first cover body cannot be opened under the action of external force.

Description

A cover structure and a motorized device Technical Field

[0001] This application relates to the field of mechanical engineering technology, and in particular to a lid structure and a motorized device. Background Technology

[0002] Nowadays, with the continuous improvement of living standards, automobiles have gradually become a part of our daily lives. At the same time, with the continuous development of intelligent technology, when a car needs refueling or charging, the refueling or charging port can automatically open or close according to a pre-set program.

[0003] However, existing cover structures that automatically open or close according to a set program are unreliable, which may lead to situations where people outside the vehicle force open the cover for theft or other purposes, or the cover opens automatically while the car is in motion. Summary of the Invention

[0004] This application provides a cover structure and a motorized device to solve the problem that the cover structure in existing motorized devices is unreliable, which may lead to situations where outsiders forcibly open the cover for theft or other purposes, or the cover automatically opens while the motorized device is in motion.

[0005] In a first aspect, embodiments of this application provide a cover structure, including:

[0006] A first cover is provided on the energy replenishment port;

[0007] A rotating device, connected to the first cover, includes a first end and a second end located at both ends, and a spiral groove is formed along the direction from the first end to the second end; and

[0008] A lifting device is partially disposed within the spiral groove. The lifting device is used to slide within the spiral groove to drive the rotating device to rotate and to displace the first cover relative to the energy replenishment port.

[0009] When the first cover is placed over the energy replenishment port, the extension direction of a portion of the spiral groove that cooperates with the lifting device is parallel to the axis of the rotating device.

[0010] Optionally, in one embodiment, the spiral groove includes a first sidewall near the first cover, and one end of the first sidewall near the first end extends gradually away from the first cover in the direction from the first end to the second end.

[0011] Optionally, in one embodiment, the rotating device includes a roller and a first rotating shaft connected to each other, the spiral groove is disposed on the roller, and the cover structure further includes a second cover body located between the first cover body and the energy replenishment port. The second cover body has a first through hole and a second through hole, the first through hole being correspondingly disposed to the energy replenishment port, and the first rotating shaft passing through the second through hole to connect to the first cover body.

[0012] Optionally, in one embodiment, the lifting device includes a protruding post, a collar, a lead screw, and a drive motor. The protruding post is disposed in the spiral groove and fixedly connected to the collar. The outer side of the collar is slidably connected to the side of the second cover facing the energy replenishment port. The collar is sleeved on the lead screw and screwed to the lead screw. The lead screw is connected to the drive motor, which drives the lead screw to rotate so that the collar moves along the axial direction of the lead screw and drives the protruding post to slide in the spiral groove.

[0013] Optionally, in one embodiment, the second cover body is provided with a protruding plate on the side facing the collar, and the collar is provided with a first protrusion and a second protrusion on the side facing the protruding plate, with the first protrusion and the second protrusion disposed on both sides of the protruding plate.

[0014] Optionally, in one embodiment, the length of the spiral groove is approximately the same as the travel distance of the protrusion as it moves along the axial direction of the lead screw.

[0015] Optionally, in one embodiment, the cross-section of the protrusion located within the spiral groove is elliptical or circular.

[0016] Optionally, in one embodiment, the cover structure includes a second pivot, which is disposed on the side of the second cover away from the first pivot. The second cover also has a third through hole, through which the second pivot passes to connect to the first cover. Both the first pivot and the second pivot are bent along the side away from the first cover.

[0017] Optionally, in one embodiment, a sealing ring is further provided on the side of the first cover facing the second cover, and the sealing ring is engaged with the first through hole to seal the energy replenishment port.

[0018] Secondly, embodiments of this application also provide a motorized device, including:

[0019] A refueling port, used for refueling or charging the motor equipment;

[0020] The cap structure is as described in any of the above claims, and the cap structure is provided corresponding to the energy replenishment port.

[0021] The cover structure provided in this application corresponds to the power supply port of a motorized device. The cover structure includes a first cover body, which covers the power supply port to achieve a sealing effect. In addition, the cover structure may also include a rotating device and a lifting device. The rotating device is connected to the first cover body and includes a first end and a second end disposed at both ends. At the same time, the rotating device also has a spiral groove along the direction from the first end to the second end, and the lifting device is partially disposed in the spiral groove.

[0022] It is understandable that when the lifting device slides in the spiral groove, the lifting device located in the spiral groove can slide up and down along the direction from the first end to the second end, and continuously abut against the groove wall. By applying a force to the groove wall in the direction of the second end, the rotating device is driven to rotate. At the same time, since the rotating device is connected to the first cover, the first cover can also be displaced relative to the energy replenishment port when the rotating device rotates, thereby realizing the opening of the energy replenishment port with a reliable mechanical structure.

[0023] Furthermore, when the first cover is placed over the refueling port, the extension direction of a portion of the spiral groove that cooperates with the lifting device is parallel to the axis of the rotating device. This allows the lifting device located within the spiral groove to abut against the groove wall and be limited by the groove wall when the first cover is opened for the purpose of theft or when the cover of a motor vehicle opens automatically during operation (i.e., when an outward force is applied to the first cover). This not only ensures that the motor vehicle cannot be easily stolen of gasoline or electricity, but also ensures the driving safety of motor vehicles such as automobiles, preventing the cover from opening automatically while the vehicle is traveling at high speed, which could lead to oil leaks or collisions with other vehicles.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] Based on the problems in the background technology described above, this application provides a lid structure 100. Please refer to Figure 1, which is a first-view (front) structural schematic diagram of the lid structure 100 provided in this application when closed.

[0038] As shown in Figure 1, the cover structure 100 in this embodiment includes a first cover 110, which covers the charging port (not shown) to achieve a sealing effect. It is understood that this embodiment does not limit the specific type of charging port; for example, it could be a fuel filler neck for a gasoline vehicle or a charging port for an electric vehicle, and can be adjusted according to actual conditions.

[0039] In addition, please refer to Figures 2 and 3. Figure 2 is a second-view (rear) structural schematic diagram of the lid structure 100 provided in the embodiment of this application when it is closed, and Figure 3 is an enlarged structural schematic diagram of part A of the lid structure 100 shown in Figure 2.

[0040] As shown in Figure 3, in this embodiment, the cover structure 100 may further include a rotating device 120 and a lifting device 130. The rotating device 120 is connected to the first cover body 110 and includes a first end 121 and a second end 122 disposed at both ends. Meanwhile, the rotating device 120 is also provided with a spiral groove 123 along the direction from the first end 121 to the second end 122, and the lifting device 130 is partially disposed in the spiral groove 123.

[0041] Meanwhile, please refer to Figures 4-6. Figure 4 is a first-view (side view) structural schematic diagram of the lid structure 100 provided in the embodiment of this application when it is half-open. Figure 5 is a second-view (back view) structural schematic diagram of the lid structure 100 provided in the embodiment of this application when it is half-open. Figure 6 is an enlarged structural schematic diagram of part B of the lid structure 100 described in Figure 5.

[0042] As can be understood, as shown in Figures 3 and 6, when the lifting device 130 slides within the spiral groove 123, the lifting device 130 located within the spiral groove 123 can slide up and down along the direction from the first end 121 to the second end 122, continuously abutting against the groove wall. By applying a force towards the second end 122 to the groove wall, this force drives the rotating device 120 to rotate through its component perpendicular to the axis of the rotating device 120. At the same time, since the rotating device 120 is connected to the first cover 110, when the rotating device 120 rotates, the first cover 110 can also be displaced relative to the energy replenishment port, thereby achieving the opening of the energy replenishment port with a reliable mechanical structure.

[0043] Furthermore, as shown in Figure 6, in this embodiment, when the first cover 110 is placed over the energy outlet, the extension direction of a portion of the spiral groove 123 that cooperates with the lifting device 130 is approximately parallel to the axis of the rotating device 120. This allows the lifting device 130 located within the spiral groove 123 to abut against the groove wall of the spiral groove 123 when a person forcibly opens the cover for theft or when the cover automatically opens while the car is in motion (i.e., when an outward force is applied to the first cover 110). The rotating device 120 is limited by the lifting device 130 in the spiral groove 123, so that the first cover 110 cannot be opened under the action of external force (in other words, when an outward force is applied to the first cover 110, the rotating device 120 cannot exert a force on the lifting device 130 to move up and down, so that the rotating device 120 and the connected first cover 110 cannot move). This not only ensures that the car cannot be easily stolen for gasoline or electricity, but also ensures the driving safety of the car and avoids the problem of the cover opening automatically when the car is driving at high speed, which could lead to oil leakage or collision with other vehicles.

[0044] Optionally, referring to Figures 3, 5, and 6, in one embodiment, the spiral groove 123 may include a first sidewall 1231, a second sidewall 1232, and a bottom wall 1233. The first sidewall 1231 extends from the first end 121 towards the second end 122, gradually moving away from the first cover 110. This creates a narrow space between the first sidewall 1231 and the bottom wall 1233 to accommodate the lifting device 130. This allows the device to be accommodated when a person forcibly opens the cover for theft or when the cover automatically opens while the vehicle is in motion (also...). When an outward force is applied to the first cover 110, it can further ensure that the lifting device 130 located in the narrow accommodating space will not slide up and down along the spiral groove 123, thereby locking the lifting device 130 in the narrow accommodating space within the spiral groove 123. This prevents the lifting device 130 located in the spiral groove 123 from sliding up and down along the spiral groove 123 when an external user applies an outward force to the first cover 110, causing the first cover 110 to shift relative to the energy replenishment port, and further improves the mechanical stability of the cover structure 100.

[0045] Optionally, as shown in Figures 4 and 6, in one embodiment, the rotating device 120 may include a roller 124 and a first rotating shaft 125 connected to each other. A spiral groove 123 is disposed on the roller 124 along the bottom to top direction of the rolling motion, so that the lifting device 130 can slide within the spiral groove 123 to drive the roller 124 to rotate. Meanwhile, the cover structure 100 also includes a second cover 140, located between the first cover 110 and the energy replenishment port. The second cover 140 has a first through hole 141 and a second through hole 142, wherein the first through hole 141 corresponds to the energy replenishment port, and the second through hole 142 corresponds to the first rotating shaft 125, so that the first rotating shaft 125 can pass through the second through hole 142 to achieve connection with the first cover 110.

[0046] It is understood that in this embodiment, when the power supply port of the motorized equipment needs to be opened to replenish its power, the lifting device 130 can slide within the spiral groove 123 to drive the roller 124 to rotate. During the rotation of the roller 124, the first rotating shaft 125 can be displaced within the second through hole 142, thereby achieving the displacement of the first cover 110 relative to the power supply port. Simultaneously, the second cover 140, positioned between the first cover 110 and the power supply port, can prevent external dust or moisture from entering the motorized equipment, thus serving a dustproof and waterproof purpose.

[0047] Additionally, please refer to Figure 4. In the above embodiment, a sealing ring 145 can be provided on the side of the first cover 110 facing the second cover 140. When the first cover 110 covers the second cover 140 and the energy replenishment port, the sealing ring 145 can be engaged with the first through hole 141 to achieve a better sealing effect on the energy replenishment port and further prevent oil leakage during vehicle operation.

[0048] It should be noted that the specific connection method between the roller 124 and the first rotating shaft 125 is not limited in this embodiment. For example, it can be a fixed connection or an integral molding, as long as the purpose of the roller 124 rotating can drive the first rotating shaft 125 to move within the second through hole 142. The specific configuration can be adjusted according to the actual situation.

[0049] Optionally, referring to Figure 6, in one embodiment, the lifting device 130 may include a protrusion 131, a collar 132, a lead screw 133, and a drive motor 134. The protrusion 131 is disposed in the spiral groove 123 and is fixedly connected to the collar 132. The collar 132 is sleeved on the lead screw 133 and screwed to the lead screw 133. The outer side of the collar 132 is slidably connected to the side of the second cover 140 facing the energy replenishment port, while the lead screw 133 is connected to the drive motor 134.

[0050] It is understandable that when the drive motor 134 drives the lead screw 133 to rotate, since the outer side of the collar 132 is slidably connected to the side of the second cover 140 facing the energy replenishment port, the collar 132 can rise along the axial direction of the lead screw 133, and the protrusion 131 fixedly connected to the collar 132 can also slide in the spiral groove 123, thereby continuously abutting against the groove wall, and applying a force towards the top of the roller 124 to drive the roller 124 to rotate. As shown in Figure 4, when the roller 124 rotates, the roller 124 can drive the first rotating shaft 125 to rotate, and through the first rotating shaft 125, drive the first cover 110 to move relative to the energy replenishment port, thereby realizing the opening of the energy replenishment port with a reliable mechanical structure.

[0051] Meanwhile, in other embodiments of this application, the cross-section of the protrusion 131 located in the spiral groove can be elliptical or circular. Compared with the angular structure of the prior art, this can reduce the wear in the spiral groove 123 and increase the friction by increasing the contact area between the protrusion 131 and the spiral groove, thereby improving the driving efficiency of the protrusion 131 driving the roller 124 to rotate.

[0052] It should be noted that in other embodiments of this application, the fixing plate 146 shown in FIG6 can be set to fix the lead screw 133 or the roller 124, thereby further improving the mechanical structural stability of the first cover 110 relative to the energy replenishment port displacement. At the same time, this embodiment does not limit the specific fixing connection method of the collar 132 and the protrusion 131. For example, it can be a one-piece molding, screw connection or welding, etc., and can be adjusted according to the actual situation.

[0053] Optionally, please refer to Figures 7 and 8. Figure 7 is a structural schematic diagram of the cap structure 100 shown in Figure 5 when the lead screw 133 is hidden, and Figure 8 is an enlarged structural schematic diagram of part C of the cap structure 100 shown in Figure 7.

[0054] As shown in Figure 8, in one embodiment, a protruding plate 143 is provided on the side of the second cover 140 facing the collar 132. Simultaneously, a first protrusion 1321 and a second protrusion 1322 are provided on the side of the collar 132 facing the protruding plate 143. The first protrusion 1321 and the second protrusion 1322 are located on both sides of the protruding plate 143, so that when the collar 132 moves upward along the circumferential direction of the lead screw 133, the collar 132 and the lead screw 133 are prevented from rotating coaxially. It can be understood that when the collar 132 and the lead screw 133 rotate coaxially, the collar 132 will not move upward along the axial direction of the lead screw 133, thus preventing the protruding post 131 from sliding within the spiral groove 123, and consequently preventing the cover from displacing relative to the energy replenishment port. Therefore, this embodiment limits the rotation direction of the collar 132 by providing the protruding plate 143, thereby ensuring the sliding stability of the protruding post 131 within the spiral groove 123.

[0055] Optionally, please refer to Figures 9-11. Figure 9 is a first-view (front) structural schematic diagram of the lid structure 100 provided in the embodiment of this application when it is fully opened. Figure 10 is a second-view (back) structural schematic diagram of the lid structure 100 provided in the embodiment of this application when it is fully opened. Figure 11 is an enlarged structural schematic diagram of part D of the lid structure 100 shown in Figure 10.

[0056] As shown in Figure 11, in one embodiment, the length of the spiral groove 123 is approximately the same as the travel distance of the protrusion 131 as it moves along the axial direction of the lead screw 133. That is, when the collar 132 moves from the bottom to the top of the lead screw 133, the protrusion 131 can also slide approximately from the bottom to the top of the spiral groove 123. This avoids the situation where the protrusion 131 has not yet slid to the top of the spiral groove 123 when the collar 132 moves to the top of the lead screw 133, resulting in the roller 124 not rotating completely. It can be understood that when the roller 124 rotates completely, the first rotating shaft 125, as shown in Figure 4, can also be fully displaced within the second through hole 142, thereby ensuring the complete opening of the first cover 110.

[0057] Optionally, referring to Figure 4, in this embodiment, the cover structure 100 may include a second rotating shaft 150. The second rotating shaft 150 is disposed on the side of the second cover 140 away from the first rotating shaft 125. At the same time, the second cover 140 also has a third through hole 144, and the second rotating shaft 150 passes through the third through hole 144 to connect the first cover 110. In this way, the first cover 110 is displaced relative to the energy replenishment port by the two rotating shafts, so as to further improve the driving efficiency of the cover structure 100 on the first cover 110.

[0058] Meanwhile, as shown in Figure 4, in the above embodiment, the first rotating shaft 125 and the second rotating shaft 150 can both be bent along the side away from the first cover 110. This can create a clearance space to avoid collision between the first rotating shaft 125 and the second rotating shaft 150 and the second cover 140 when they rotate. It can also create a gap between the first cover 110 and the second cover 140 when the first cover 110 is displaced relative to the energy replenishment port to open the energy replenishment port. This can prevent the first cover 110 and the second cover 140 from colliding when the first cover 110 is displaced relative to the energy replenishment port to open the energy replenishment port.

[0059] This application also provides a motorized device, including a refueling or charging port for the motorized device, and a cover structure 100 mentioned in any of the above embodiments. The cover structure 100 is provided corresponding to the refueling port to enable the opening or closing of the refueling port. It is understood that the motorized device provided in this embodiment can be a motor vehicle such as a pickup truck or car, or a motorized vessel such as a ship or yacht; that is, any device containing the aforementioned cover device can be included within the scope of protection of this application.

[0060] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0061] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0062] The above provides a detailed description of the cap structure and motorized device provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
