[0040] The two logo bearing platforms 3 are respectively slidingly connected to the logo switching slide rail 4.

[0041] The linear driving mechanism 2 is mounted on the housing part, and the output end of the linear driving mechanism 2 is configured to output linear motion. The transmission input end of the intermediate transmission member 204 is rotationally connected to the output end of the linear driving mechanism 2, and the two transmission output ends of the intermediate transmission member 204 in the transverse direction are respectively rotationally connected to the two logo carrying platforms 3, that is, the vertical height change of the two logo carrying platforms 3 when moving along the logo switching slide rail 4 is matched by the swing of the intermediate transmission member 204 relative to the output end of the linear driving mechanism 2. The intermediate transmission member 204 is configured to drive the two logo carrying platforms 3 to slide and switch between the first display configuration and the second display configuration synchronously under the driving of the linear driving mechanism 2.

[0042] In the first display configuration, the two logo carrying platforms 3 are respectively located in the first temporary storage section 5 and the display track section 7. In the second display configuration, the two logo carrying platforms 3 are respectively located in the display track section 7 and the second temporary storage section 9.

[0043] In the embodiment, the first temporary storage section 5 and the second temporary storage section 9 are lower than the display track section 7, so that the corresponding logo carrying platform 3 can gradually lift and extend into the logo opening at the transition section when moving from the corresponding temporary storage section to the display track section 7, that is, the height of the display track section 7 can meet the requirement of the logo entering the logo opening for display, and the display track section 7 only corresponds to the logo opening, and the transition sections on both sides bear the function of gradually making the logo enter the logo opening, while the two outermost temporary storage sections are hidden under the car shell.

[0044] The embodiment sets the logo switching sliding rail 4 in the shell part, and sets the logo switching sliding rail 4 to include a first temporary storage section 5, a first transition section 6, a display track section 7, a second transition section 8 and a second temporary storage section 9, the first temporary storage section 5, the display track section 7 and the second temporary storage section 9 extend laterally, and the display track section 7 is higher than the first temporary storage section 5 and the second temporary storage section 9 in the vertical direction. Further, two logo carrying platforms 3 slidingly connected to the logo switching sliding rail 4 are provided, and a linear driving mechanism 2 and an intermediate transmission member 204 for synchronously driving the movement of the two logo carrying platforms 3 are provided, so that the two logo carrying platforms 3 can be switched between a first display configuration and a second display configuration. In the first display configuration, one logo carrying platform 3 is hidden in the first temporary storage section 5, and the other logo carrying platform 3 is located in the display track section 7, and the logo thereon is located at the logo opening of the external car shell 10.

In this embodiment, the moving direction is lateral, and the height difference of the two temporary storage sections relative to the display track section 7 only needs to satisfy the thickness of the corresponding logo carrying platform 3, so that the space occupied by the overall device in the height direction can be greatly reduced, and this form of structure for realizing logo switching by moving back and forth along the sliding rail is also more simple than the scheme of lifting two logos, thereby solving the problems of complex mechanism and large space occupied in the height direction existing in the existing logo switching mode by lifting.

[0045] The specific structure of the logo switching device of the embodiment will be further described below:

[0046] In the embodiment, the shell part can specifically include a base shell 1, a first track plate 401 and a second track plate 402. The linear driving mechanism 2 is installed on the base shell 1. The first track plate 401 and the second track plate 402 are arranged on the two sides of the linear driving mechanism 2 with a spacing, and the faces of the first track plate 401 and the second track plate 402 towards the linear driving mechanism 2 are respectively provided with a first track groove 403 and a second track groove, which cooperate to form the above-mentioned logo switching sliding rail 4, that is, the extension direction of the first track groove 403 and the second track groove matches the arrangement of the above-mentioned temporary storage section, transition section and display track section 7, and sliding connection can be realized by setting corresponding sliding blocks 203 or pulleys and the like on the logo carrying platform 3. In other embodiments, guide sliding rails can also be provided on the first track plate 401 and the second track plate 402, and corresponding pulleys can be provided on the logo carrying platform 3 to realize sliding connection, which is not limited specifically herein.

[0047] Further, the base shell 1 can specifically include a bottom plate 101 and two connecting plates 102. The lower ends of the two connecting plates 102 are respectively connected to the bottom plate 101 and located at the two ends of the longitudinal direction of the bottom plate 101, and the upper ends of the two connecting plates 102 are used to be connected to the external vehicle shell 10. That is, the bottom plate 101 and the two connecting plates 102 cooperate to form a rectangular space extending in the transverse direction on the bottom surface of the external vehicle shell 10.

[0048] Further, in order to minimize the gap between the vehicle logo opening and the vehicle logo, and reduce the wear caused by the shaking or vibration of the vehicle logo during the rapid switching process, the shell part can further include a first mounting seat, a second mounting seat, an end shaft 406 and an elastic support 407.

[0049] The first mounting seat and the second mounting seat are respectively mounted on the base shell 1 and located on both sides of the driving part. The first end of the first track plate 401 is rotationally connected to the first mounting seat with the rotation axis parallel to the longitudinal direction, and the first end of the second track plate 402 is rotationally connected to the first mounting seat with the rotation axis parallel to the longitudinal direction.

The elastic support 407 is connected between the end shaft 406 and the base shell 1, and the elastic support 407 is configured to provide the required support force of the end shaft 406 and has a compression stroke and a stretching stroke. The elastic support can be a spring or other component that can output an elastic force. That is, the first track plate 401 and the second track plate 402 can swing around the connection position with the corresponding mounting seat, and the swing amplitude is limited by the elastic support 407 to a certain extent. When the driving part drives the two vehicle logo carrying platforms 3 to move, the vibration generated by the driving part can be absorbed by the elastic support 407, and when the corresponding vehicle logo carrying platform 3 moves rapidly, the impact force formed by the vehicle logo carrying platform 3 can be absorbed to a certain extent, thereby improving the service life of the vehicle logo carrying platform 3.

[0050] In the embodiment, the linear driving mechanism 2 can specifically include a motor 201, a lead screw 202 and a sliding block 203.

Specifically, one longitudinal outwardly extending transmission shaft 205 can be arranged on each of the two end surfaces of the sliding block 203 in the longitudinal direction, and the two transmission shafts 205 are respectively rotationally connected to the transmission input end of the intermediate transmission member 204.

[0051] In the embodiment, the intermediate transmission member 204 can be a transmission plate 2041, which can be rectangular in shape. The transmission plate 2041 is provided with at least one downwardly extending transmission input arm 2042, which is configured to be rotatably connected to the output end of the linear driving mechanism 2 (the number of transmission input arms 2042 can be two, which are arranged on the two sides of the transmission plate 2041 in the longitudinal direction and located in the middle region in the transverse direction, and the lower ends of the two transmission input arms 2042 can be provided with a rotating shaft hole to realize the rotatable connection with the transmission shaft 205). The transmission plate 2041 is provided with at least one transversely outwardly extending transmission output arm 2043 at each end, which is configured to be rotatably connected to two logo carrying platforms 3 (the number of transmission output arms 2043 can be four, which are arranged at the four end points of the rectangular transmission plate 2041, respectively, and extend in the transverse direction away from the transmission plate 2041 at the corresponding end points, and the extending ends of the transmission output arms 2043 can also be provided with a rotating shaft for connecting with the corresponding logo carrying platform 3, which can be detachably connected to the transmission output arm 2043 for easy assembly).

The sliding end 3012 is lower than the driving end 3011 in the vertical direction, and the driving end 3011 is arranged between the sliding end 3012 and the logo carrying platform 3, so that the height space required for the intermediate transmission plate 2041 to swing can be utilized by the height difference between the sliding end 3012 and the logo carrying platform 3, that is, the height space is fully utilized, so that the space required by the logo switching device in the height direction can be further compressed.

[0053] Specifically, the number of the sliding extension arms 301 on each logo carrying platform 3 can be two, which are arranged at the two ends of the logo carrying platform 3 in the longitudinal direction and correspond to the first track plate 401 and the second track plate 402 respectively. The number of the sliding ends 3012 on each sliding extension arm 301 can be two, which are arranged at the two ends of the sliding extension arm 301 in the transverse direction. Specifically, the sliding end 3012 can be a pulley for extending into and slidingly connecting to the corresponding track groove. The pulley can include a connecting shaft connected to the sliding extension arm 301 and a bearing installed on the connecting shaft, and the outer ring surface of the bearing is slidingly connected to the corresponding track groove. The number of the driving end 3011 on each sliding extension arm 301 can be one, which is located between the two sliding ends 3012. Specifically, the driving end 3011 can be a rotating shaft hole opened on the sliding extension arm 301, which is used for rotatingly connecting with the rotating shaft on the transmission output arm 2043.

[0054] With the development of new energy vehicles, higher and higher requirements are put forward for the integration and miniaturization of automobile interior components, especially the space of the trunk position where the logo of the new energy vehicle is placed. Due to the characteristics of the front layout of the new energy vehicle, the vertical space of the front part is small, so higher requirements are put forward for the height of the logo switching device in the vertical direction. The embodiment fully compresses the height of the logo switching device in the vertical direction through the design of the logo switching movement track combined with the specific structure design, thereby meeting the development demand of component miniaturization. Moreover, the two logos corresponding to the logo switching device are usually a common logo and a more valuable special logo. The logo switching device of the embodiment is switched by horizontal reciprocation, and compared with the existing lifting switching mode, the switching path is short and simple, that is, the switching speed can be greatly improved, thereby realizing automatic and rapid switching to replace the common logo when the valuable special logo in the display is touched or damaged by human (which can be detected by setting a pressure sensor or other sensing structure), and protecting the valuable special logo.
