Description

Technical Field

[0001] The invention relates to the field of automobile accessories, in particular to an automobile logo changing mechanism. Background Art

[0002] Cars have become a widely used means of transportation in people's lives, but with the popularization of vehicle manufacturing technology, people's pursuit of vehicle functions has also become higher. It is often necessary to reflect the technological sense of the vehicle in order to better arouse people's desire to buy.

[0003] At the same time, because many vehicles are often parked on the roadside or in other open-air environments, the surface of the vehicle is easily damaged. Among them, the protruding design of the vehicle logo makes it most vulnerable to damage in open-air environments.

[0004] Therefore, some vehicles will have an automated transformation design for the vehicle pole. Under normal circumstances, the vehicle logo is displayed on the vehicle body. When the vehicle does not need to display the vehicle logo, the vehicle logo can naturally retract into the vehicle body, and a replacement seat is filled in the original vehicle logo position to ensure the integrity of the vehicle body. This method often adopts a separate driving method for the vehicle logo and the replacement seat, that is, the vehicle logo is driven first, and then the replacement seat is driven. This method requires two different driving devices to complete the driving work of the vehicle logo and the replacement seat respectively. At the same time, because the movement trajectory between the vehicle logo and the replacement seat is intersecting, the driving time of the two driving devices needs to be strictly controlled to avoid interference, resulting in the shortcomings of the automatic logo-changing mechanism occupying a large space, high cost, and a long replacement cycle. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a car logo replacement mechanism which only requires a single drive device to complete the replacement of the car logo and the replacement seat, and can avoid interference between the car logo and the replacement seat to ensure replacement efficiency.

[0006] The technical solution adopted by the present invention to solve the above-mentioned problem is: a car logo-changing mechanism, including a car shell, a mounting seat for mounting the car logo, and a replacement seat. The top of the car shell is provided with a mounting hole for cooperating with the mounting seat or the replacement seat. When the car logo is in normal use, the mounting seat is fixedly connected to the mounting hole. When the car logo is hidden, the mounting seat is disengaged from the mounting hole, and the replacement seat is fixedly connected to the mounting hole. The mounting seat is driven by a driving component, and the driving component is used to fix the mounting seat on the mounting hole or disengage the mounting seat from the mounting hole. The replacement seat is transmission-connected to one end of a driven component, and the other end of the driven component is arranged on the disengagement movement trajectory of the mounting seat. When the mounting seat abuts against the other end of the driven component and drives the driven component to rotate, the replacement seat moves to the mounting hole.

[0007] Compared with the prior art, the advantages of the present invention are that: the mounting seat is driven by only one driving component, and the mounting seat is first disengaged from the mounting hole during the driving process, and then after the disengagement is completed, the mounting seat continues to move until the mounting seat is disengaged from the moving trajectory of the replacement seat, and the mounting seat begins to resist against the driven component, and the replacement seat is driven by the driven component to move to the mounting hole to replace the mounting seat. This process is driven by only one driving component to complete the disengagement of the mounting seat and the installation of the replacement seat, reducing the design of the driving component, making the label changing mechanism small in space and low in cost. At the same time, because the replacement seat is driven to be installed by the movement of the mounting seat, there is no need to worry about the execution interference between the replacement seat and the mounting seat due to inaccurate motion control, which ensures the stability of the replacement cycle between the mounting seat and the replacement seat, and there is no need to wait for the mounting seat to complete the movement before moving the replacement seat due to fear of interference.

[0008] As an improvement of the present invention, the driven assembly includes a connecting bent rod, the connecting bent rod being hinged on the side wall of the vehicle shell, one end of the connecting bent rod being arranged on the disengagement movement track of the mounting seat, and the replacement seat being hinged on the side wall, the replacement seat being also hinged on the side wall, the replacement seat being provided with a track groove on the side away from the connection with the top of the vehicle shell, and the other end of the connecting bent rod being provided with a connecting column connected to the track groove. When the mounting seat drives the connecting bent rod to rotate, the connecting column drives the replacement seat to rotate. Through the improvement, due to the design of the connecting bent rod, one end of the connecting bent rod can be arranged on the disengagement movement track of the mounting seat, and the other end can be arranged around the glue-disengagement movement track of the mounting seat, so as to complete the connection between the replacement seat and the mounting hole with a smaller stroke. At the same time, the design of the track groove can reduce the movement track of the replacement seat to meet the connection conditions on the upper side wall of the replacement seat hinge, avoid the replacement seat from needing to move synchronously with the other end of the connecting bent rod, increase the movement track of the replacement seat, thereby causing the time for the mounting seat to disengage from the movement track of the replacement seat to increase, affecting the efficiency of replacing the vehicle logo.

[0009] As an improvement of the present invention, the driven assembly also includes a reset spring, one end of the reset spring is fixedly connected to one end of the connecting bent rod, and the other end of the reset spring is fixedly connected to the side wall. Through the improvement, through the design of the reset spring, when the driving assembly drives the mounting seat to be installed on the mounting hole, the driven assembly can be reset in time and drive the replacement seat to detach from the mounting hole to ensure that the mounting seat will not interfere with the replacement seat during the installation process.

[0010] As an improvement of the present invention, the drive assembly includes a driving motor, a driving rod, a limiting rod and a driving limiting plate, wherein the driving limiting plate is provided with a driving limiting slot, one end of the driving rod is driven and connected to the driving motor, the other end of the driving rod is hinged to the mounting seat, one end of the limiting rod is movably connected to the driving motor, the limiting rod is provided with a limiting column movably connected to the driving limiting slot, the other end of the limiting rod is hinged to the mounting seat, and a spacing is provided between the hinge point between the driving rod and the mounting seat and the hinge point between the limiting rod and the mounting seat. Through the improvement, the design of the driving motor and the driving rod can make the mounting seat move away from the driving motor, ensuring that the mounting seat will not interfere with the driving motor during the movement, and the design of the limiting rod and the driving limiting plate can ensure the moving trajectory of the limiting rod, so that the moving trajectory of the limiting rod is adapted to the moving trajectory of the mounting seat, and the limiting rod and the driving rod are respectively hinged to two positions of the mounting seat to ensure that the mounting seat remains in a vertical state during the movement, avoiding uncontrollable interference caused by the rotation of the mounting seat.

[0011] As an improvement of the present invention, the driving rod includes a first driving rod and a second driving rod, the driving end of the driving motor is provided with a first connecting rod and a second connecting rod, one end of the first connecting rod is hinged to the driving motor, and the other end of the first connecting rod is hinged to one end of the second connecting rod, the first driving rod is bent in a direction away from the driving limit plate, one end of the first driving rod is rotatably connected to the driving motor, the bending part of the first driving rod is hinged to the second connecting rod, the second driving rod has two bending parts in total, one end of the second driving rod is coaxially arranged with one end of the first driving rod and is rotatably connected to the driving motor, and the bending part of the second driving rod close to the driving motor is bent in a direction away from the driving limit plate The cam is connected to the second drive rod and the second drive rod is connected to the cam frame, and the cam frame is connected to the first drive rod and the second drive rod respectively.

[0012] Through the improvements, in the overall label-changing mechanism, there is no fixed connection device between either the mounting seat or the replacement seat and the mounting hole, and there is only a driving motor as a power source and a locking structure. When the driving motor is not working, relying solely on the driving force of the driving motor for fixed connection can easily lead to an unstable connection between the mounting seat and the replacement seat. When the mounting seat is subjected to external pressure, it is easy to directly detach from the mounting hole. The design of the first connecting rod, the second connecting rod and the cylinder spring can avoid the unstable fixation of the mounting seat and the replacement seat. The cylinder spring is used to provide resistance to ensure that the second driving rod will not rotate due to a small external force. At the same time, the cylinder spring has a moving stroke, and the design of the cylinder spring can effectively control the effective stroke between the driving rod and the driving motor. When the driving rod makes the mounting seat installed on the mounting hole during the rotation process, it helps to drive the motor to rotate in the reverse direction. The design of the first connecting rod and the second connecting rod is that when the mounting seat is fixed on the mounting hole, the connection between the first connecting rod and the second connecting rod is set in a straight line or bent toward one side, and when the mounting seat is separated from the mounting hole, the connection between the first connecting rod and the second connecting rod is bent toward the other side, and the two directions are opposite. When a turn is required, the mechanism can only be changed by rotating the first connecting rod by the driving motor, and when the mounting seat is fixed When the mounting hole is mounted on the mounting seat, the external force acting on the mounting seat will only make the first connecting rod and the second connecting rod approach each other, and the first connecting rod and the abutment block will abut each other, so that the first connecting rod and the second connecting rod cannot approach each other, thereby causing the mounting seat to be unable to detach from the mounting hole, ensuring the stability of the mounting seat installation, thus forming a self-locking effect, ensuring that external pressure is unlikely to cause the mounting seat to move, unless the external pressure exceeds the load of the label changing mechanism. The bending design of the first driving rod can increase the design length of the first connecting rod and the second connecting rod, making the first connecting rod and the second connecting rod more controllable. The bending design of the second driving rod facilitates the installation of the cylinder spring, because the cylinder spring is a standard part with fixed specifications, avoiding the high cost of customization, and the bending design of the second driving rod can solve the problem.

[0013] As an improvement of the present invention, a movable groove is provided on the drive motor, one end of the limit rod is limited and movably connected in the movable groove, the drive motor is rotatably connected to the side wall, and the rotation connection between the drive motor and the vehicle shell is coaxially arranged with the rotation connection between the first drive rod and the drive motor. When the mounting seat begins to disengage from the mounting hole, the first connecting rod and the second connecting rod move away from each other, the cylinder spring opens, and the drive motor starts to rotate until the first connecting rod and the second connecting rod are arranged in a straight line, completing the preparation for disengagement of the mounting seat and the mounting hole, and then the first connecting rod and the second connecting rod approach each other from another direction, and the position of the drive motor remains unchanged. When the mounting seat is moved, the first driving rod, the second driving rod and the limiting rod begin to rotate to drive the mounting seat to move along the driving limiting groove. Through the above-mentioned modification, after the mounting seat is installed in the mounting hole, the first connecting rod and the second connecting rod are arranged in a straight line. At this time, the driving motor continues to drive the first connecting rod and the second connecting rod to continue to move, while the mounting seat is no longer able to move. Therefore, the driving motor rotates under the action of the reaction force, so that the first connecting rod and the second connecting rod can continue to move, and then the self-locking state can be completed. The driving motor is arranged inside the vehicle shell and is fully protected and difficult to be touched by external pressure, thereby ensuring the stability of the mounting seat installed on the mounting hole. Conversely, when the mounting seat needs to be separated from the mounting hole, the driving motor must first complete its own rotation, so that the first connecting rod and the second connecting rod are arranged in a straight line, and then the self-locking state is released before the mounting seat can be driven out of the mounting hole.

[0014] As an improvement of the present invention, a movable part is provided in the movable groove, and the movable part is movably connected in the movable groove. The movable part is also provided with a hinge hole for hinged connection with one end of the limit rod. Through the improvement and the design of the movable part, not only can the movement of one end of the limit rod in the movable groove be made more stable, but also friction between one end of the limit rod and the movable groove can be avoided, which causes wear of one end of the limit rod or the movable groove, thereby ensuring the service life of the limit rod and the movable groove.

[0015] As an improvement of the present invention, a first spring in a contracted state is provided in the movable groove, and the first spring abuts against the movable part to provide assistance for rotating the drive motor. Through the improvement, in the preparation process of the mounting seat to disengage from the mounting hole, the drive motor needs to complete the rotation action first and release the self-locking state. When the first connecting rod starts to drive, the abutment relationship between the first connecting rod and the abutment block is eliminated, and the drive motor resumes rotation. Under the action of the first spring, the drive motor can be promoted to rotate until one end of the limit rod abuts against one end of the movable groove.

[0016] As an improvement of the present invention, the end of the driving motor away from the driving end is provided with a second spring in a stretched state, the driving motor is provided with a limiting shaft fixedly connected to one end of the second spring, the side wall is provided with an abutment groove, the limiting shaft is limited to move in the abutment groove, and the side of the side wall close to the driving motor is also fixedly connected with a fixed shaft, and the other end of the second spring is fixedly connected to the fixed shaft. Through the improvement, the function is the same as that of the first spring. When the first connecting rod is driven to drive the mounting seat to disengage from the mounting hole, the driving motor is first completed to rotate to release the self-locking.

[0017] As an improvement of the present invention, a connecting plate for fixedly connecting the first driving rod and the second driving rod is provided at the fixed connection between the first driving rod and the second driving rod away from the driving motor, a sliding groove is provided on the side wall, the center of the sliding groove is provided at the rotation connection between the first driving rod and the driving motor, and a sliding buckle is provided on the side of the connecting plate close to the side wall, and the sliding buckle is used to ensure that the connecting plate moves along the side wall, and the connecting plate is also provided with a positioning groove for positioning the limit rod, and the positioning groove is used to prevent the limit rod from deflecting and getting stuck during the rotation process. Through the improvement, the design of the sliding groove and the sliding buckle can ensure the stability of the rotation of the first driving rod and the second driving rod, and prevent the first driving rod and the second driving rod from derailing. The design of the positioning groove can ensure the stability of the rotation of the limit rod, and prevent the limit rod from derailing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0033] like Figure 1-3As shown, a car logo-changing mechanism comprises a car shell 1, a mounting seat 2 for mounting the car logo, and a replacement seat 3. The top of the car shell 1 is provided with a mounting hole 1.1 for cooperating with the mounting seat 2 or the replacement seat 3. When the car logo is in normal use, the mounting seat 2 is fixedly connected to the mounting hole 1.1. When the car logo is hidden, the mounting seat 2 is disengaged from the mounting hole 1.1, and the replacement seat 3 is fixedly connected to the mounting hole 1.1. The mounting seat 2 is drive-connected to a driving component 4, and the driving component 4 is used to fix the mounting seat 2 on the mounting hole 1.1 or disengage the mounting seat 2 from the mounting hole 1.1. The replacement seat 3 is transmission-connected to one end of a driven component 5, and the other end of the driven component 5 is arranged on the disengagement movement trajectory of the mounting seat 2. When the mounting seat 2 abuts against the other end of the driven component 5 and drives the driven component 5 to rotate, the replacement seat 3 moves to the mounting hole 1.1.

[0034] like Figure 1-4 As shown, the driven assembly 5 includes a connecting bent rod 5.1, which is hinged on the side wall 1.2 of the vehicle shell 1. One end of the connecting bent rod 5.1 is set on the disengagement movement track of the mounting seat 2. A matching groove for matching with the connecting bent rod 5.1 is provided on the mounting seat 2. When the mounting seat 2 moves to one end of the connecting bent rod 5.1, one end of the connecting bent rod 5.1 enters the matching groove, thereby ensuring the rotation stability of the connecting bent rod 5.1. The replacement seat 3 is also hinged on the side wall 1.2. The replacement seat 3 is provided with a track groove 3.1 on the side away from the connection with the top of the vehicle shell 1, and the other end of the connecting bent rod 5.1 is provided with a connecting column 5.1.1 connected to the track groove 3.1. When the mounting seat 2 drives the connecting bent rod 5.1 to rotate, the connecting column 5.1.1 drives the replacement seat 3 to rotate. The driven assembly 5 also includes a return spring 5.2, one end of the return spring 5.2 is fixedly connected to one end of the connecting bent rod 5.1, and the other end of the return spring 5.2 is fixedly connected to the side wall 1.2.

[0035] like Figure 1-7As shown, the driving assembly 4 includes a driving motor 4.1, a driving rod, a limiting rod 4.4 and a driving limiting plate 4.5, the driving limiting plate 4.5 is provided with a driving limiting groove 4.5.1, one end of the driving rod is connected to the driving motor 4.1, the other end of the driving rod is hinged to the mounting seat 2, one end of the limiting rod 4.4 is connected to the driving motor 4.1, the limiting rod 4.4 is provided with a limiting column 4.4.1 movably connected to the driving limiting groove 4.5.1, the other end of the limiting rod 4.4 is hinged to the mounting seat 2, and the hinge between the driving rod and the mounting seat 2 and the limiting rod 4 .4 is provided with a spacing between the hinged joints with the mounting base 2, the driving rod includes a first driving rod 4.2 and a second driving rod 4.3, the driving end of the driving motor 4.1 is provided with a first connecting rod 4.6 and a second connecting rod 4.7, one end of the first connecting rod 4.6 is hinged to the driving motor 4.1, the other end of the first connecting rod 4.6 is hinged to one end of the second connecting rod 4.7, the first driving rod 4.2 is bent in the direction away from the driving limit plate 4.5, one end of the first driving rod 4.2 is rotatably connected to the driving motor 4.1, and the bending part of the first driving rod 4.2 is hinged to the second connecting rod 4.7. The two connecting rods 4.7 are hinged, and the second drive rod 4.3 is provided with two bends. One end of the second drive rod 4.3 is coaxially arranged with one end of the first drive rod 4.2 and is rotatably connected to the drive motor 4.1. The bend of the second drive rod 4.3 close to the drive motor 4.1 is bent in the direction close to the drive limit plate 4.5, and the bend of the second drive rod 4.3 away from the drive motor 4.1 is bent in the direction away from the drive limit plate 4.5. The other end of the first drive rod 4.2 is fixedly connected to the bend of the second drive rod 4.3 away from the drive motor 4.1 The other end of the second drive rod 4.3 is hinged to the mounting base 2. A cylinder spring 4.8 is provided between the drive motor 4.1 and the second drive rod 4.3. One end of the cylinder spring 4.8 is hinged to the drive motor 4.1, and the other end of the cylinder spring 4.8 is hinged to the bend of the second drive rod 4.3 near the drive motor 4.1. A contact block 4.1.1 is provided on the side of the drive motor 4.1 near the first connecting rod 4.6. When the mounting base 2 is fixedly connected to the mounting hole 1.1, the cylinder spring 4.8 is in a compressed state, and the first connecting rod 4.6 abuts against the contact block 4.1.1. After the mounting base 2 is installed in the mounting hole 1.1, the drive motor 4.1 enters a self-locking drive process, which only drives a small angle. This angle ensures that the drive motor 4.1 can rotate at an angle. At the same time, it is necessary to prevent the second connecting rod 4.7 from entering a tilted state to avoid the self-locking drive angle being too large, which would cause the mounting base 2 to begin to disengage from the mounting hole 1.1.

[0036] like Figure 5-8As shown, the drive motor 4.1 is provided with a movable groove 4.1.2, one end of the limit rod 4.4 is limited and movably connected in the movable groove 4.1.2, the drive motor 4.1 is rotatably connected to the side wall 1.2, and the rotation connection between the drive motor 4.1 and the vehicle shell 1 is coaxially arranged with the rotation connection between the first drive rod 4.2 and the drive motor 4.1. When the mounting seat 2 begins to disengage from the mounting hole 1.1, the first connecting rod 4.6 and the second connecting rod 4.7 move away from each other, the cylinder spring 4.8 opens, and the drive motor 4.1 starts to rotate until the first connecting rod 4.6 and the second connecting rod 4.7 are arranged in a straight line, completing the preparation for disengagement of the mounting seat 2 from the mounting hole 1.1, and then the first The connecting rod 4.6 and the second connecting rod 4.7 approach each other from another direction, the driving motor 4.1 remains in position, the first driving rod 4.2, the second driving rod 4.3 and the limiting rod 4.4 start to rotate to drive the mounting base 2 to move along the driving limiting groove 4.5.1, and a movable part 4.9 is provided in the movable groove 4.1.2. The movable part 4.9 is movable and connected in the movable groove 4.1.2. The movable part 4.9 is also provided with a hinge hole 4.9.1 for being hinged to one end of the limiting rod 4.4. A first spring 4.10 in a contracted state is provided in the movable groove 4.1.2. The first spring 4.10 is offset against the movable part 4.9 to provide assistance for rotating the driving motor 4.1.

[0037] like Figure 1 、 Figure 2 、 Figure 5-9 As shown, the end of the driving motor 4.1 away from the driving end is provided with a second spring 4.11 in a stretched state, and the driving motor 4.1 is provided with a limiting shaft 4.1.3 fixedly connected to one end of the second spring 4.11, and the side wall 1.2 is provided with an abutment groove 1.3, and the limiting shaft 4.1.3 is limited to move in the abutment groove 1.3, and the side wall 1.2 close to the driving motor 4.1 is also fixedly connected with a fixed shaft 1.4, and the other end of the second spring 4.11 is fixedly connected to the fixed shaft 1.4. During the rotation of the driving motor 4.1, the cooperation between the limiting shaft 4.1.3 and the abutment groove 1.3 limits the rotation angle of the driving motor 4.1, and at the same time, the driving motor 4.1 is also provided with a matching hole for limiting the rotation range of the fixed shaft 1.4. The design of the fixed shaft 1.4 and the matching hole further limits the rotation angle of the driving motor 4.1. Figure 1 、 Figure 2 It can be seen that the angle of rotation of the drive motor 4.1 is small, and is only sufficient to meet the self-locking requirement.

[0038] like Figure 10As shown, a connecting plate 6 for fixedly connecting the first driving rod 4.2 and the second driving rod 4.3 is provided at a fixed connection between the first driving rod 4.2 and the second driving rod 4.3 away from the driving motor 4.1, and a slide groove 1.5 is provided on the side wall 1.2. The center of the slide groove 1.5 is set at the rotation connection between the first driving rod 4.2 and the driving motor 4.1, and a slide buckle 6.1 is provided on the side of the connecting plate 6 close to the side wall 1.2, which cooperates with the slide groove 1.5. The slide buckle 6.1 is used to ensure that the connecting plate 6 moves along the side wall 1.2, and a positioning groove 6.2 for positioning the limit rod 4.4 is also provided on the connecting plate 6. The positioning groove 6.2 is used to prevent the limit rod 4.4 from deflecting and causing jamming during rotation.

[0039] like Figure 11 As shown, point A is the hinged connection between the second drive rod 4.3 and the mounting base 2, point B is the hinged connection between the limit rod 4.4 and the mounting base 2, point C is the rotation center of the drive motor 4.1, and the arc where point A is located is the movement trajectory of the mounting base 2. Because the relative position between point A and point B is fixed, the movement trajectory of point B can be deduced, and the rotation center of point B can be obtained. The center line of the drive limit groove 4.5.1 is concentric with the movement trajectory of point B. Therefore, the rotation center of the drive limit groove 4.5.1, that is, point D where the limit rod 4.4 connects to the drive motor 4.1, can be calculated from the movement trajectory of point B to design the structure of the drive output groove 4.5.1. During the operation of the label changing mechanism, because the trajectory of point B is restricted by the drive limit groove 4.5.1, the position of point D is unique, so that during the self-locking drive process, the drive motor 4.1 can be prompted to rotate.

[0040] like Figure 1 、 Figure 2 、 Figure 12 、 Figure 13 As shown, the mounting base 2 includes a base 2.1 and a support base 2.2. The support base 2.2 is used to fix the vehicle logo. The support base 2.2 is connected to the base 2.1 by a limit block 2.1.2 along the vertical direction. A cavity 2.1.1 for the support base 2.2 to move is provided in the base 2.1. A buffer plate 2.6 is provided between the support base 2.2 and the bottom of the cavity 2.1.1. The upper end surface of the buffer plate 2.6 is against the support base 2.2, and a spring 2.3 is provided between the lower end surface of the buffer plate 2.6 and the bottom of the cavity.

[0041] There are two buffer plates 2.6 in total. The two buffer plates 2.6 are fixedly connected to both sides of the movable support rod 2.5 respectively. The other end of the buffer plate away from the movable support rod is limitedly and movably connected to the base 2.1.

[0042] A tension assembly 2.4 is provided within the support base 2.2. The tension assembly 2.4 includes a tension ball 2.4.1 and a tension rope 2.4.2. The tension rope 2.4.2 is arranged along the axis of the movable support rod 2.5. One end of the tension rope 2.4.2 is fixedly connected to the tension ball 2.4.1, and the other end of the tension rope 2.4.2 is connected to an elastic member 7.3. The tension assembly 2.4 is used to maintain the support base 2.2 and the buffer plate 2.6 in a state of abutment. The elastic member 2.4.3 includes a hinged joint, which also has a spherical groove for cooperating with another tension ball 2.4.1. One end of the hinge is connected to a tension spring. The elastic force of the spring maintains the tension ball 2.4.1 on the hinge, which applies force to the tension ball 2.2.1 on the support base 2.2 via the tension rope 2.4.2.

[0043] The design of the mounting base 2 is such that when the vehicle logo on the support base 2.2 is subjected to external force, the spring 2.3 can relieve part of the external force. Compared with the traditional structural design in which the vehicle logo is directly fixed to the vehicle shell, the force-releasing capability is stronger, the probability of damage to the vehicle logo is reduced, and the vehicle logo is not easily damaged.

[0044] The design of the spring 2.3 and the tension component 2.4 is such that the force of the spring 2.3 is upward and the force of the tension component 2.4 is downward, which can keep the support base 2.2 in a lightly stressed equilibrium state, that is, the support base 2.2 can be moved even under extremely small force, keeping the support base 2.2 in a force-unloading state, thereby better protecting the vehicle logo.

[0045] The above description is merely a description of the preferred embodiment of the present invention and is not to be construed as limiting the scope of the claims. The present invention is not limited to the above embodiment, and variations in the specific structure are permitted. Any variations within the scope of the independent claims of the present invention are also within the scope of protection of the present invention.
