[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0035] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0036] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0037] This disclosure provides a vehicle. The vehicle can be a new energy vehicle, a hybrid vehicle, a traditional fuel vehicle, or other types of vehicles. The vehicle may include a body, a chassis, a powertrain, and a sign-raising device. The chassis is connected to the body, and the powertrain is mounted on the chassis and suspended from the body to provide driving power. The powertrain may include an engine and / or an electric motor. For example, for a traditional fuel vehicle, the powertrain includes an engine; for a new energy vehicle, the powertrain includes an engine; and for a hybrid vehicle, the powertrain includes both an engine and an electric motor. The body may include a main body, a hood, a front bumper, a trunk lid, and a rear bumper. The hood, front bumper, trunk lid, and rear bumper are connected to the main body. The sign-raising device may be located inside the hood, front bumper, trunk lid, or rear bumper to raise and lower the sign. Correspondingly, the hood, front bumper, trunk lid, and rear bumper may have openings for exposing the sign. The sign-raising device can retract the sign through these openings to the inside of the vehicle body when the sign is touched, thus providing an anti-theft function for the sign. Thus, installing a sign-up lift device on the vehicle not only provides anti-theft functionality but also enhances the aesthetics, improving the driver's experience. The sign-up lift device can be installed in various locations such as the hood, front bumper, trunk lid, and rear bumper, offering a wide range of options to suit different needs.

[0038] See Figure 1 , Figure 2 , Figure 4 The sign lifting device includes a mounting frame 1, a first sign 2, a second sign 3, and a drive assembly 4. The mounting frame 1 includes a movable block 11 and a frame 12, with the frame 12 rotatably connected to the movable block 11 about a straight line in the first direction X. The first sign 2 and the second sign 3 can be vehicle logos; one is more expensive than the other. The first sign 2 and the second sign 3 are spaced apart on the frame 12 along the second direction Y and are rotatably connected to the frame 12 about a straight line in the first direction X. The first sign 2 and the second sign 3 are located on opposite sides of the movable block 11, and the first direction X intersects the second direction Y. The drive assembly 4 drives the movable block 11 to move along the second direction Y and includes a guide rail 41 extending along the second direction Y. The guide rail 41 has a straight portion 411 and a curved portion 412 connected along the second direction Y. The curved portion 412 bends towards an opening, that is, it bends away from the movable block 11. When the first mark 2 is fitted into the opening, the first mark 2 is located in the curved portion 412, and the second mark 3 is located in the straight portion 411; when the second mark 3 is fitted into the opening, the second mark 3 is located in the curved portion 412, and the first mark 2 is located in the straight portion 411.

[0039] When the first sign 2 is engaged within the opening, and the second sign 3 needs to engage with the opening, the driving assembly 4 drives the moving block 11 to move along the second direction Y. The moving block 11 can drive the frame 12 to move along the second direction Y. The frame 12 drives the first sign 2 and the second sign 3 to move along the extension direction of the guide rail 41 until the second sign 3 engages with the opening. Since the guide rail 41 has a curved portion 412 and a straight portion 411, during the process of switching from the first sign 2 to the second sign 3, the first sign 2 will move from the curved portion 412 to the straight portion 411, and the second sign 3 will move from the straight portion 411 to the curved portion 412. Furthermore, the first sign 2 and the second sign 3 are rotatably connected to the frame 12, so the first sign 2 and the second sign 3 will not interfere with the vehicle body.

[0040] When the second sign 3 is engaged within the opening, and the first sign 2 needs to engage with the opening, the driving assembly 4 drives the moving block 11 to move along the second direction Y. The moving block 11 can drive the frame 12 to move along the second direction Y. The frame 12 drives the first sign 2 and the second sign 3 to move along the extension direction of the guide rail 41 until the first sign 2 engages with the opening. Since the guide rail 41 has a curved portion 412 and a straight portion 411, during the process of switching the second sign 3 to the first sign 2, the second sign 3 will move from the curved portion 412 to the straight portion 411, and the first sign 2 will move from the straight portion 411 to the curved portion 412. Furthermore, the first sign 2 and the second sign 3 are rotatably connected to the frame 12, so the first sign 2 and the second sign 3 will not interfere with the vehicle body.

[0041] In other words, the movement of the sign lifting device during the process of switching from the first sign 2 to the second sign 3 is in the opposite direction to the movement of the sign lifting device during the process of switching from the second sign 3 to the first sign 2.

[0042] Thus, the driving component 4 can drive the moving block 11 to move along the second direction Y. The moving block 11 drives the frame 12, the first sign 2, and the second sign 3 to move along the extension direction of the guide rail 41, so that one of the first sign 2 and the second sign 3 fits into the opening, facilitating the switching between the first sign 2 and the second sign 3 and helping to protect valuable signs. This sign lifting device has a simple structure, small size, light weight, and low cost, reducing the space occupied by the vehicle and increasing the vehicle's driving range.

[0043] In one embodiment of this disclosure, the first emblem 2 and the second emblem 3 have similar structures, differing only in that one of the first emblem 2 and the second emblem 3 may have a gold-plated layer or a diamond-encrusted layer, making it expensive, while the other is an ordinary emblem, making it inexpensive. Thus, on important occasions, the valuable emblem can be paired with the opening to enhance the vehicle's luxurious feel; when the vehicle is not in use, the ordinary emblem can be paired with the opening, keeping the valuable emblem inside the vehicle body and preventing its theft.

[0044] In one embodiment of this disclosure, see Figure 2 , Figure 4 There can be two straight sections 411 and one curved section 412. The curved section 412 can be an arc shape curving towards the opening. One end of the curved section 412 is connected to one straight section 411, and the other end is connected to another straight section 411. In other words, the guide rail 41 has a symmetrical shape along the second direction Y. This facilitates the engagement of the first mark 2 and the second mark 3 with the opening when they are in the curved section 412.

[0045] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 4 The first mark 2 has a first sliding member 21, and the second mark 3 has a second sliding member 31. A guide rail 41 is slidably engaged with the first sliding member 21 and the second sliding member 31, respectively. When the first mark 2 is engaged within the opening, the first sliding member 21 is located in the curved portion 412, and the second sliding member 31 is located in the straight portion 411. When the second mark 3 is engaged within the opening, the second sliding member 31 is located in the curved portion 412, and the first sliding member 21 is located in the straight portion 411. For example, the first sliding member 21 and the second sliding member 31 can be block-shaped, rod-shaped, or similar. Thus, the sliding engagement of the first sliding member 21 with the guide rail 41 facilitates the movement of the first mark 2 along the guide rail 41; the sliding engagement of the second sliding member 31 with the guide rail 41 facilitates the movement of the second mark 3 along the guide rail 41.

[0046] In one embodiment of this disclosure, see Figure 2 , Figure 4 The guide rail 41 includes a base plate and two side plates, which are spaced apart in a direction away from the opening; in other words, they are spaced apart in a direction away from the moving block 11. The base plate is connected to the two side plates, and the two side plates are located on the same side of the base plate. The first sliding member 21 and the second sliding member 31 can be located between the two side plates. In other words, the guide rail 41 is provided with a guide groove, which has a straight portion 411 and a curved portion 412. The first sliding member 21 and the second sliding member 31 slide in the guide groove to realize the movement of the first mark 2 and the second mark 3 along the guide rail 41.

[0047] In one embodiment of this disclosure, the first sliding member 21 and the second sliding member 31 have sliding grooves, and the guide rail 41 cooperates with the sliding grooves to achieve sliding cooperation between the guide rail 41 and the first sliding member 21 and the second sliding member 31 respectively.

[0048] In one embodiment of this disclosure, see Figure 2 , Figure 3A rolling element 22 is fitted onto the first sliding member 21 and the second sliding member 31. The rolling element 22 is rotatably connected to the first sliding member 21 and the second sliding member 31, respectively, and rolls between the two side plates. For example, the rolling element 22 can be a cylindrical rolling element such as a roller or a bearing. In this way, the friction between the guide rail 41 and the first sliding member 21 and the second sliding member 31 can be reduced, facilitating the movement of the first mark 2 and the second mark 3.

[0049] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 4 Both the first sliding member 21 and the second sliding member 31 include a connecting portion 211 and a stop portion 212. The stop portion 212 is integrally connected to the end of the connecting portion 211 away from the guide rail 41. The shapes of the connecting portion 211 and the stop portion 212 can be cylindrical, prismatic, or other geometric shapes. The rolling member 22 is rotatably sleeved on the connecting portion 211. The outer diameter of the stop portion 212 is larger than the outer diameter of the connecting portion 211 and larger than the distance between the two side plates. Thus, during the movement of the first mark 2 and the second mark 3, the stop portion 212 cannot extend into the straight portion 411 and the curved portion 412, thus having a limiting function and improving the stability of the movement of the first mark 2 and the second mark 3.

[0050] In one embodiment of this disclosure, see Figure 2 , Figure 3 The movable block 11 has a first rotating shaft 111 extending along a first direction X. The outer peripheral surface of the first rotating shaft 111 includes a plurality of clearance planes and a plurality of arc surfaces distributed along its own circumference, with at least two clearance planes being parallel. The frame 12 is provided with a first mating hole and a first notch 121 communicating with the first mating hole. The distance between the two sidewalls of the first notch 121 distributed along a second direction Y is less than the diameter of the first mating hole and not less than the distance between the two parallel clearance planes. In one example, the outer peripheral surface of the first rotating shaft 111 includes two clearance planes and two arc surfaces distributed along its own circumference. The arc surfaces and clearance planes are alternately distributed. The two arc surfaces are symmetrically arranged about the axis of the first rotating shaft 111, and the two clearance planes are symmetrically arranged about the axis of the first rotating shaft 111. Thus, by rotating the frame 12 so that the arc surface is directly facing the first notch 121, since the distance between the two side walls of the first notch 121 distributed along the second direction Y is not less than the distance between the two parallel clearance planes, the first rotating shaft 111 can be disengaged from the first mating hole through the first notch 121, which facilitates the installation and disassembly of the frame 12 and the first rotating shaft 111.

[0051] In one embodiment of this disclosure, see Figure 3A convex ring 112 is fitted onto the first rotating shaft 111. The convex ring 112 extends circumferentially along the first rotating shaft 111 and is integrally connected to the first rotating shaft 111. The diameter of the convex ring 112 is larger than the diameter of the first rotating shaft 111 and the diameter of the first mating hole. In this way, by contacting the frame 12 with the convex ring 112, the frame 12 can be limited along the first direction X, improving the stability of the sign lifting device.

[0052] In one embodiment of this disclosure, see Figure 2 , Figure 3 The frame 12 has a second pivot 122 extending along a first direction X. The first mark 2 and the second mark 3 each have an auxiliary portion 23. The auxiliary portion 23 has a second mating hole and a second notch 231 communicating with the second mating hole. The distance between the two sidewalls of the second notch 231 distributed along the second direction Y is less than the diameter of the second mating hole and not less than the diameter of the second pivot 122. Thus, the second pivot 122 is prevented from disengaging from the auxiliary portion 23 by means of the second notch 231.

[0053] In one embodiment of this disclosure, see Figure 3 The auxiliary part 23 is plate-shaped, and the plane of the auxiliary part 23 is perpendicular to the plane of the first mark 2. The first slider 21 and the second slider 31 are respectively connected to the auxiliary part 23. In this way, the first mark 2 can be connected to the first slider 21, and the second mark 3 can be connected to the second slider 31 through the auxiliary part 23.

[0054] In one embodiment of this disclosure, see Figure 1 , Figure 2 The drive assembly 4 includes a support block 42, a screw 43, and a drive component 44. The support block 42 is mounted on the vehicle body. The screw 43 is rotatably connected to the support block 42, and its axis is parallel to the line containing the second direction Y. The screw 43 passes through and is threadedly connected to the movable block 11. The drive component 44 is coaxially fixedly connected to the screw 43 via a coupling and is used to drive the screw 43 to rotate, thereby moving the first mark 2 and the second mark 3 along the guide rail 41. For example, the drive component 44 can be a motor, a tilting cylinder, or other drive components. Thus, the drive component 44 can drive the screw 43 to rotate, and the screw 43 drives the movable component to move along the guide rail 41, facilitating the lifting and lowering movement of the first mark 2 and the second mark 3.

[0055] In one embodiment of this disclosure, the vehicle body may also be provided with a fixing block, and the end of the screw 43 away from the drive member 44 may pass through the fixing block and be rotatably connected to the fixing block to support the screw 43.

[0056] In one embodiment of this disclosure, see Figure 1The sign lifting device may also include a connecting block 5, which can be fixed to the inside of the vehicle body and is fixedly connected to the guide rail 41 to fix the position of the guide rail 41. Connecting blocks 5 can be provided at both ends of the guide rail 41 to improve the stability of the guide rail 41.

[0057] In one embodiment of this disclosure, see Figure 1 , Figure 2 , Figure 3 There are two guide rails 41, which are arranged in parallel and extend along the second direction Y. The mounting bracket 1 is located between the two guide rails 41. There are two first rotating shafts 111, which are coaxially arranged and located on both sides of the moving block 11. There are two sets of second rotating shafts 122, which are spaced apart along the second direction Y. The two second rotating shafts 122 in the same set are spaced apart along the first direction X. There are two sets of auxiliary parts 23, which are spaced apart along the second direction Y. The two auxiliary parts 23 in the same set are spaced apart along the first direction X. The two auxiliary parts 23 in the same set are respectively connected to the same mark. Each auxiliary part 23 is rotatably connected to one second rotating shaft 122. There are two sets of first sliding members 21, which are spaced apart along the first direction X. Two second sliders 31 located in the same group are spaced apart along the second direction Y. One group of second sliders 31 is connected to an auxiliary part 23 of the first mark 2, and the two second sliders 31 in the same group are located on both sides of the second rotating shaft 122. There are two groups of second sliders 31, and the two groups of second sliders 31 are spaced apart along the first direction X. Two second sliders 31 located in the same group are spaced apart along the second direction Y. One group of second sliders 31 is connected to an auxiliary part 23 of the second mark 3, and the two second sliders 31 in the same group are located on both sides of the second rotating shaft 122.

[0058] In one embodiment of this disclosure, the sign lifting device has dimensions of 116mm × 254mm × 44mm and a weight of 1kg, which reduces the space occupied by the sign lifting device on the vehicle body, reduces the weight of the vehicle, and increases the vehicle's driving range.

[0059] In one embodiment of this disclosure, the vehicle further includes a controller, and the vehicle body also includes a sensing device. The sensing device is used to send a switching signal to the controller after sensing that the valuable sign has been touched. After receiving the switching signal, the controller controls the drive unit 44 to start, so that the ordinary sign cooperates with the opening and the valuable sign is located inside the vehicle body, thereby realizing the anti-theft function of the sign.

[0060] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
