Description

TECHNICAL AREA

[0001] The present disclosure relates to the field of cover devices and in particular a cover device in a vehicle-mounted device. BACKGROUND

[0002] An existing vehicle-mounted device comprises a vehicle-mounted element housing and a cover device. The cover device has a cover element for covering an opening in the vehicle-mounted element housing. However, when the cover device covers the opening in the vehicle-mounted element housing, an opening in the cover device itself remains open, facilitating the ingress of dust. SUMMARY OF THE REVELATION

[0003] The inventor of the present disclosure has found that in the prior art, even if an additional element is provided to cover the opening of the cover device itself, an additional drive device must be provided to drive the additional element. This results in a complex design and a large size for the vehicle-mounted device.

[0004] The present disclosure provides a covering device to solve the aforementioned problem. The covering device comprises a mounting base, a covering element, a receiving opening cover, and a drive device. The mounting base defines a receiving cavity and is provided with a receiving opening. The covering element is connected to the mounting base and has a covered state and a rest state. The receiving opening cover is connected to the covering element and has an open state, in which the receiving opening cover opens the receiving opening, and a closed state, in which the receiving opening cover closes the receiving opening. The drive device is configured to drive the covering element to switch between the covered state and the rest state.When the cover element is in the rest position, the receiving opening cover is in the open position, and the cover element is held in the receiving cavity and covers the receiving opening. When the cover element is in the covered position, the cover element is at least partially outside the receiving cavity and the receiving opening, and the receiving opening cover is driven into the closed position by the cover element.

[0005] According to some embodiments, the cover device further comprises a shaft arranged on the mounting base. The receiving opening cover has a roller curtain, the roller curtain being connected to the shaft at a first end and being wound up by winding it around the shaft, and the roller curtain being connected to the cover element at a second end opposite the first end and being unwound by the drive mechanism of the cover element. The receiving opening cover is in the open state when the roller curtain is wound up, and the receiving opening cover is in the closed state when the roller curtain is unwound.

[0006] According to some embodiments, the cover element is designed to rotate about an axis relative to the mounting base in order to switch between the covered state and the rest state, and the roller curtain is movably connected to the cover element at the second end.

[0007] According to some embodiments, the cover element is provided with a receiving slot, the receiving slot being arranged at an angle to the axis. The cover device further comprises a connecting pin, the roller blind being connected to the connecting pin at its second end, and the connecting pin being received in the receiving slot and movable along the receiving slot. The connecting pin is located at an end of the receiving slot furthest from the axis when the roller blind is wound up, and at an end of the receiving slot closer to the axis when the roller blind is unwound.

[0008] According to some embodiments, the receiving slot is arranged perpendicular to the axis.

[0009] According to some embodiments, the cover element is provided with two receiving slots, the two receiving slots being located on opposite sides of the cover element. The cover device further comprises two connecting pins, the two connecting pins being each received by the two receiving slots.

[0010] According to some embodiments, the covering device further includes a return element designed in such a way that, when the covering element switches from the covered state to the rest state, it causes the roller curtain to be wound up.

[0011] According to some embodiments, the cover element comprises a first cover plate and a second cover plate, wherein the first cover plate is rotatably connected to the second cover plate and the second cover plate is rotatably connected to the mounting base. When the cover element is in its resting state, it is folded so that the first cover plate overlaps the second cover plate, and when the cover element is in the covered state, the first and second cover plates are connected to each other to jointly cover an object. The receiving slot is provided on the second cover plate.

[0012] According to some embodiments, the cover device further comprises a gear device by which the drive device drives the first cover plate and the second cover plate to movement.

[0013] According to some embodiments, the transmission device comprises a first gear, a second gear, a third gear, and a drive belt. The first gear is fixedly connected to the second cover plate, and the drive mechanism is designed to cause the first gear to rotate. The second gear is located on the second cover plate and meshes with the first gear. The third gear is fixedly connected to the first cover plate. The drive belt is arranged around the second and third gears such that rotation of the second gear causes rotation of the third gear.

[0014] The present disclosure further provides for a vehicle-mounted device. The vehicle-mounted device comprises a vehicle-mounted element housing and the aforementioned cover device. The vehicle-mounted element housing has a housing opening. The cover element opens the housing opening when the cover element is in the rest state, and the cover element covers the housing opening when the cover element is in the covered state.

[0015] According to some embodiments, the vehicle-mounted element housing is designed to accommodate a vehicle-mounted element, and the vehicle-mounted element comprises a vehicle-mounted camera, a vehicle-mounted laser radar, a vehicle-mounted detection radar, a vehicle charging port, or a vehicle rearview mirror.

[0016] In contrast to the prior art, in the covering device of the present disclosure the covering functions of the covering element and the receiving opening cover can be achieved by means of a drive device without the need for a separate drive device for the receiving opening cover.

[0017] Since the drive device can move the cover element and the receiving opening cover simultaneously, it also only takes a short time to move the cover element into the covered state and the receiving opening cover into the closed state.

[0018] Since the cover element includes the first and second cover plates, which move relative to each other, and the first cover plate overlaps the second cover plate when the cover element is in its resting state, the size of the cover element is also small, resulting in a small opening area over the radius of the vehicle.

[0021] The following describes various specific embodiments of the present disclosure with reference to the drawings that form part of this patent specification. It is understood that the same reference number is used for identical components in the following drawings.

[0022] The following describes various specific embodiments of the present disclosure with reference to the drawings that form part of this patent specification. It is understood that, although terms indicating directions such as "upper / upper / upper", "lower / lower / lower", "left", "right", "inside", "outside", etc., are used in the present disclosure to describe various exemplary structural parts and elements, these terms are used here only for the sake of simplicity and are determined on the basis of the exemplary orientations shown in the drawings. Since the arrangements disclosed in the present disclosure can exist in several directions in the embodiments, these directional indications are merely illustrative and should not be considered as limitations.

[0023] Fig. Figure 1 is a perspective view of a vehicle-mounted device according to the present disclosure. As in Fig. As shown in Figure 1, the vehicle-mounted device comprises a vehicle-mounted element housing 102, a cover device 100, and a drive device 116. The vehicle-mounted element housing 102 defines a housing cavity 106 and a housing opening 104. The vehicle-mounted element is arranged in the housing cavity 106. The vehicle-mounted element comprises a vehicle-mounted camera, a vehicle-mounted laser radar, a vehicle-mounted detection radar, a vehicle charging port, or a vehicle rearview mirror. The cover device 100 comprises a mounting base 112 and a cover element 120. The mounting base 112 defines a receiving cavity 114 and is provided with a receiving opening 105 on the top of the receiving cavity 114. The cover element 120 is connected to the mounting base 112 and has a covered state and a rest state.When the cover element 120 is in the rest state, it is housed in the receiving cavity 114, covering the receiving opening 105 and opening the housing opening 104. When the cover element 120 is in the covered state, it is located at least partially outside the receiving cavity 114 and the receiving opening 105, covering the housing opening 104. In this disclosure, the cover element 120 is configured to rotate relative to the mounting base 112 to switch between the covered state and the rest state. The drive device 116 is configured to drive the cover element 120 to rotate relative to the mounting base 112 to switch between the covered state and the rest state. In this disclosure, the drive device 116 is arranged outside the mounting base 112.

[0024] Fig. 2 is an exploded view of the in Fig. Cover device 100 as shown in 1. As in Fig. As shown in Figure 2, the cover element 120 comprises a first cover plate 211 and a second cover plate 212. The first cover plate 211 is rotatably connected to the second cover plate 212. The second cover plate 212 is rotatably connected to the mounting base 112. When the cover element 120 is in its rest position, it is folded so that the first cover plate 211 overlaps the second cover plate 212, allowing the first cover plate 211 to cover the receiving opening 105. When the cover element 120 is in the covered position, the first cover plate 211 and the second cover plate 212 are connected to each other to jointly cover an object (e.g., the housing opening 104).

[0025] As in Fig. As shown in Figure 2, the cover device 100 further includes a gear device 202. The drive device 116 drives the first cover plate 211 and the second cover plate 212 by means of the gear device 202. In the present disclosure, the gear device 202 includes a first gear 232, a second gear 234, a third gear 238, and a drive belt 236. The first gear 232 meshes with the second gear 234. The second gear 234, by means of the drive belt 236, which is arranged around the second gear 234 and the third gear 238, causes the third gear 238 to rotate in order to rotate the second cover plate 212.

[0026] As in Fig. As shown in Figure 2, the cover device 100 further includes a receiving opening cover 222. The receiving opening cover 222 is connected to the cover element 120 and has an open state, in which the receiving opening cover 222 opens the receiving opening 105, and a closed state, in which the receiving opening cover 222 closes the receiving opening 105. The receiving opening cover 222 can be driven by the cover element 120 to move from the open state to the closed state. In the present disclosure, the receiving opening cover 222 includes a roller curtain 223. The roller curtain 223 can be wound up and unwound. When the roller curtain 223 is wound up, the receiving opening cover 222 is in the open position. When the roller curtain 223 is unwound, the receiving opening cover 222 is in the closed state.

[0027] Fig. 3 is a perspective view of the in Fig. Mounting base 112 shown in 1-2. As in Fig. As shown in Figure 3, the mounting base 112 is essentially cuboid. A through-opening 301 is provided in one side wall of the mounting base 112. A drive shaft (not shown) of the drive device 116 can pass through the through-opening 301 to connect to the first gear 232, which is located in the receiving cavity 114, in order to drive the first gear 232 to rotation.

[0028] As in Fig. As shown in Figure 3, the cover device further includes a shaft 302. The shaft 302 is arranged in the receiving cavity 114 in a first direction (e.g., a direction from front to back) and is connected to the mounting base 112. The shaft 302 is used to receive the roller curtain 223, so that the roller curtain 223 can be wound around the shaft 302.

[0029] Fig. Figure 4 is a partial exploded view of the first cover plate 211, the second cover plate 212, the shaft 302, the roller curtain 223 and the gear device 202, which are located in Fig. 2 are shown. As in Fig. As shown in Figure 4, the first gear 232 is fixedly connected to the second cover plate 212. The second cover plate 212 is designed to rotate about an axis X relative to the mounting base 112. The axis X is a central axis of the first gear 232. In the present disclosure, the axis X extends in the first direction (e.g., from front to back). The second gear 234 is fixedly connected to the second cover plate 212 and meshes with the first gear 232, so that the rotation of the first gear 232 can cause the rotation of the second gear 234. The third gear 238 is fixedly connected to the first cover plate 211. The drive belt 236 is arranged around the second gear 234 and the third gear 238 such that the rotation of the second gear 234 causes the rotation of the third gear 238.In particular, the first cover plate 211 is configured to rotate about an axis Y relative to the second cover plate 212. The axis Y is a central axis of the third gear 238. The axis Y extends in the first direction (e.g., the front-to-back direction) parallel to the axis X. When the cover element 120 is in its rest position, the first cover plate 211 and the second cover plate 212 are folded and arranged substantially parallel to each other. When the cover element 120 is in the covered position, the first cover plate 211 and the second cover plate 212 are connected and essentially form a plate. In this case, the first cover plate and the second cover plate are substantially perpendicular to a plane on which the receiving opening 105 is located on the top of the mounting base 112, thus covering the object to be covered (e.g., the housing opening 104).

[0030] As in Fig. As shown in Figure 4, the roller curtain 223 is connected at a first end to the shaft 302. The roller curtain 223 is connected at a second end opposite the first end to the cover element 120, so that the roller curtain 223 can be unwound by the drive of the cover element 120. In the present disclosure, the roller curtain 223 is movably connected at the second end to the cover element 120. In particular, the cover device further includes two connecting pins 421. The second end of the roller curtain 223 is connected to the two connecting pins 421. The second cover plate 212 is provided with two receiving slots 411. The two connecting pins 421 are each received in the two receiving slots 411. The receiving slots 411 are arranged on opposite sides of the second cover plate 212 and are formed by recessing them inwards from an outer surface of the second cover plate 212.The receiving slots 411 are arranged essentially at an angle to the axis X. In an exemplary embodiment of the present disclosure, the receiving slots 411 are perpendicular to the axis X, and when the second cover plate 212 is rotated relative to the mounting base 112, the receiving slots 411 are always perpendicular to the axis X. The connecting pins 421 can move in the direction of the receiving slots 411. When the connecting pins 421 are located at ends of the receiving slots 411 furthest from the axis X, the roller curtain 223 is wound up. When the connecting pins 421 are located at ends of the receiving slots 411 near the axis X, the roller curtain 223 is unwound.

[0031] It should be noted that, although two connecting pins 421 and two receiving slots 411 are shown in the present disclosure, at least one connecting pin 421 and at least one receiving slot 411 fall within the scope of protection of the present disclosure.

[0032] As in Fig. As shown in Figure 4, the cover device further includes a return element 401. The return element 401 is designed such that it winds up the roller curtain 223 during the switching of the cover element 120 from the covered state to the rest state. The return element 401 can, for example, be a spring arranged on the roller curtain 223 in such a way that the roller curtain 223 tends to be wound up.

[0033] Fig. Figure 5 is a perspective partial view of the cover device with the cover element 120 in the covered state and the receiving opening cover 222 in a closed state. The process of covering the housing opening 104 of the vehicle-mounted element housing 102 by the cover device is described below with reference to Fig. 5 and the Fig. 1 described, in which the cover element 120 of the cover device is in the rest state and the receiving opening cover 222 is in the open state.

[0034] As in Fig. 5 and Fig. As shown in Figure 1, when it is desired to cover the housing opening 104 of the vehicle-mounted element housing 102, the drive device 116 drives the first gear 232 so that it rotates about the axis X in a first direction of rotation (e.g., counterclockwise). Since the first gear 232 is fixedly connected to the second cover plate 212, the second cover plate 212 also rotates about the axis X in the first direction of rotation. Because the first gear 232 is externally meshed with the second gear 234, and the second gear 234 is in gear connection with the third gear 238 via the drive belt 236, the third gear 238 can rotate the first cover plate 211 about the axis Y in a second direction of rotation (e.g., clockwise) relative to the second cover plate 212.Thus, the first cover plate 211 and the second cover plate 212 rotate in opposite directions to move from the rest state to the covered state, thereby covering the housing opening 104 of the vehicle-mounted element housing 102.

[0035] Fig. Figure 6 is a partial side view of the cover device at a point in time during the movement of the cover element 120 from the rest state to the covered state and during the movement of the receiving opening cover 222 from the open state to the closed state. As shown in Fig.As shown in Figure 6, the roller blind 223 is in the open position and the connecting pins 421 are located at the ends of the receiving slots 411 furthest from the axis X when the cover element 120 is in the rest position. During the movement of the cover element 120 from the rest position to the covered position, the ends of the receiving slots 411 furthest from the axis X are gradually raised due to the movement of the second cover plate 212 about the axis X, so that the roller blind 223 is gradually unwound. Since the return element 401 always exerts a force on the roller blind 223 to keep it under tension, the connecting pins 421 are always subjected to a force F in the direction in which the roller blind 223 is unwound.Since the force F is at an angle to the receiving slots 411, the force F has a component Fo in the direction of extension of the receiving slots 411, such that the connecting pins 421 in the receiving slots 411 are moved towards parts of the receiving slots 411 near the axis X, until the connecting pins 421 reach the ends of the receiving slots 411 near the axis X. This moves the roller curtain 223 from the open state to the closed state, and the roller curtain 223 closes the receiving opening 105.

[0036] It should be noted that although the roller curtain 223 is used in the present disclosure as one embodiment of the receiving opening cover 222, it is apparent to those skilled in the art that in another embodiment the receiving opening cover 222 may also have a component that can be folded and unfolded in several layers without being wound around the shaft 302. In another embodiment, the receiving opening cover 222 may also be a plate connectable to the cover element 120, which is moved into its open and closed state by movement and / or rotation.

[0037] It should be noted that although the first cover plate 211 and the second cover plate 212 are used as cover elements 120 in the present disclosure, it is apparent to those skilled in the art that in another embodiment all cover elements 120 which include a cover component / cover plate fall within the scope of protection of the present disclosure.

[0038] The inventor of the present disclosure has found that, in the prior art, for example, the vehicle-mounted element housing is arranged on the roof of a vehicle, and a roof-side sheet metal must be provided with an opening adapted to the receiving opening so that the cover element can extend out of the vehicle. However, when the cover element extends out of the vehicle and covers the housing opening of the vehicle-mounted element housing, the opening of the roof-side sheet metal is in the open state, and dust can enter the roof. Even if an additional cover element is provided for opening the sheet metal, an additional drive mechanism is required, resulting in a complex design.

[0039] In the covering device of the present disclosure, the covering functions of the covering element and the receiving opening cover can be achieved by means of a drive device, without the need for a separate drive device for the receiving opening cover. Since the drive device can move the covering element and the receiving opening cover simultaneously, it also takes only a short time to move the covering element into the covered state and the receiving opening cover into the closed state.

[0040] Since the cover element includes the first and second cover plates, which move relative to each other, and the first cover plate overlaps the second cover plate when the cover element is in its resting state, the size of the cover element is also small, resulting in a small opening area over the radius of the vehicle.

[0041] Although the present disclosure has been described with reference to the examples of embodiments described above, various alternatives, modifications, variants, improvements, and / or substantial equivalents that are currently known, foreseeable, or expected shortly may be obvious, at least to the person skilled in the art. Furthermore, the technical effects and / or technical problems described in this patent specification are exemplary, not limiting; therefore, the disclosure in this patent specification may also be used to solve other technical problems and may exhibit other technical effects. Accordingly, the exemplary embodiments of the present disclosure, as set forth above, are illustrative and not intended to be limiting.Various modifications can therefore be made without deviating from the fundamental idea or scope of this disclosure. Therefore, this disclosure is intended to include all known or previously disclosed alternatives, modifications, variants, improvements, and / or substantial equivalents.
