[0035] In order to reduce the thickness of the navigation screen while ensuring the use stability of the navigation screen and improve the aesthetic degree of the navigation screen, this embodiment discloses a navigation screen and a detachable central control system. Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a navigation screen disclosed in this embodiment. The navigation screen 100 includes a screen 110, a metal middle frame 120, and a glass back plate 130. Among them, the screen 110 and the glass back plate 130 are respectively fixedly arranged on the front and back sides of the metal middle frame 120. That is to say, the metal middle frame 120 is sandwiched between the screen 110 and the glass back plate 130. In this embodiment, the material of the metal middle frame 120 is preferably aluminum or an aluminum alloy product. And using the glass back plate 130 can reduce signal shielding and signal interference compared with using a back plate made of metal material, thereby ensuring the communication quality between the navigation screen 100 and the car's center console.

[0036] Please refer to Figure 2 , Figure 2A schematic structural diagram of a metal middle frame in a navigation screen in one direction disclosed in this embodiment. The metal middle frame 120 has a tiled accommodation cavity 121 formed by a semi-enclosed structure. The accommodation cavity 121 is used to arrange a power supply component 122, a PCB board 123, a wiring groove 124, and an electrical connector 125. In this embodiment, the accommodation cavity 121 is set to a tiled shape, that is, a flat shape, which can reduce the depth of the accommodation cavity 121, that is, reduce the thickness of the metal middle frame 120, that is, can thin the thickness of the navigation screen 100. Among them, the power supply component 122 and the PCB board 123 are electrically connected to supply power to the PCB board 123 through the power supply component 122. The wiring groove 124 is a groove on the inner wall of the accommodation cavity 121, for example, it can be a groove on the bottom inner wall of the accommodation cavity 121. A signal transmission FPC 126 is arranged in the wiring groove 124, and the signal transmission FPC 126 is used to connect the PCB board 123 and the center console to realize the electrical connection between the PCB board 123 and the center console. One end of the signal transmission FPC 126 is connected to the PCB board 123, and the other end of the signal transmission FPC 126 is connected to the electrical connector 125, so that the navigation screen 100 can be electrically connected to the center console through the electrical connector 125. In this embodiment, the center console is the center console of the vehicle, and the navigation screen 100 can transmit signals with the center console. The wiring groove 124 needs to have a certain depth to accommodate the signal transmission FPC 126. Since the signal transmission FPC 126 is flexible, arranging the signal transmission FPC 126 in the wiring groove 124 can play a role in protecting and fixing the signal transmission FPC 126, so that the interfaces at both ends of the signal transmission FPC 126 can be firmly connected to the PCB board 123 and the electrical connector 125 respectively, ensuring the connection stability of the navigation screen 100, that is, ensuring the use stability of the navigation screen 100. And opening a groove in the accommodation cavity 121 to arrange the signal transmission FPC 126 also improves the accommodation space of the accommodation cavity 121, thereby being able to reduce the depth of the accommodation cavity 121 (that is, the thickness of the metal middle frame 120), and further thinning the thickness of the navigation screen 100 and improving the aesthetic degree of the navigation screen 100.

[0037] In an alternative embodiment, please refer to Figure 3 , Figure 3A cross-sectional view and a partial enlarged view of a metal middle frame in a navigation screen disclosed in this embodiment. The wiring groove 124 is arranged at the rear side of the power supply component 122. When the signal transmission FPC 126 is arranged in the wiring groove 124, a preset distance is provided between the signal transmission FPC 126 and the power supply component 122. In this embodiment, the wiring groove 124 is arranged at the rear side of the power supply component 122, and the signal transmission FPC 126 is also arranged at the rear side of the power supply component 122, which is more convenient for workers to assemble parts during the assembly process. Since the power supply component 122 will generate heat or expand and deform during the charging or discharging process, when the signal transmission FPC 126 is arranged in the wiring groove 124, there is a certain interval distance between the signal transmission FPC 126 and the power supply component 122, which can protect the signal transmission FPC 126 from being overly interfered by the heat generated by the power supply component 122, thereby ensuring the signal transmission quality and service life of the signal transmission FPC 126.

[0038] In an alternative embodiment, please refer to Figure 3 and Figure 4 , Figure 4 A schematic structural view of another direction of the metal middle frame in a navigation screen disclosed in this embodiment. An insulating layer 127 is further arranged between the power supply component 122 and the wiring groove 124. In this embodiment, the insulating layer 127 can be an insulating tape. Since the signal transmission FPC 126 is arranged in the wiring groove 124, therefore, an insulating layer 127 is arranged between the power supply component 122 and the wiring groove 124 to protect the signal transmission FPC 126, so as to ensure the signal transmission quality and service life of the signal transmission FPC 126.

[0039] In an alternative embodiment, please refer to Figure 2 , the power supply component 122 and the PCB board 123 are arranged flatly in the accommodation cavity 121. In this embodiment, the flat arrangement of the power supply component 122 and the PCB board 123 can make better use of the accommodation space in the accommodation cavity 121, so that the accommodation cavity 121 can accommodate the components of the navigation screen 100 with a smaller depth, that is, the thickness of the navigation screen 100 can be reduced, and the aesthetic degree of the navigation screen 100 can be improved. Preferably, the arrangement shown in Figure 3 can be selected to arrange the power supply component 122 and the PCB board 123. At this time, the overlapping area of the projections of the power supply component 122 and the PCB board 123 is the smallest, which is the overlapping area of the projection of the PCB board 123.

[0040] In an alternative embodiment, please refer to Figure 3, the height of the power supply component 122 is higher than that of the PCB board 123. In this embodiment, since electronic components also need to be installed on the PCB board 123, the height of the power supply component 122 can be slightly higher than that of the PCB board 123. In this way, after the electronic components are installed on the PCB board 123, the height of the power supply component 122 can be basically the same as or slightly higher than that of the PCB board with the electronic components installed, ensuring that there is no large height difference in the accommodation cavity. Thus, after the screen 110 is installed on the metal middle frame 120, the structure of the screen 110 is more stable, playing a certain protective role for the screen 110.

[0041] In an alternative embodiment, please refer to Figure 2 , a preset distance is provided between the power supply component 122 and the PCB board 123. Separating the PCB board 123 and the power supply component 122 can prevent the PCB board 123 from being adversely affected by the heat generation and deformation of the power supply component 122 during the use of the navigation screen 100.

[0042] In an alternative embodiment, a protective layer is provided between the power supply component 122 and the PCB board 123 and the screen 110. In this embodiment, the protective layer preferably can be selected as foam, which can play a role in buffering and shock absorption. The protective layer can completely cover the power supply component 122 and the PCB board 123, or may not completely cover them, and the quantity can also be selected according to the actual situation.

[0043] In an alternative embodiment, please refer to Figure 5 , Figure 5 is a schematic structural diagram of a power supply component in a navigation screen disclosed in this embodiment. The power supply component 122 includes a battery 1221, a buffer layer 1222, and a heat sink 1223. The battery 1221 is spaced from the PCB board 123. A heat sink 1223 is attached to the side of the battery 1221 close to the screen 110, and a buffer layer 1222 is attached to the heat sink 1223. In this embodiment, please refer to Figure 2, the power supply component 122 includes a buffer layer 1222, a heat sink 1223, and a battery 1221 that are stacked in sequence. Since the battery 1221 generates heat during charging or discharging, the battery 1221 is spaced apart from the PCB board 123, which can prevent the battery 1221 from affecting the PCB board 123 due to heat generation or deformation. A heat sink 1223 is attached to the surface of the battery 1221 to assist in the heat dissipation of the battery 1221 and improve the heat dissipation efficiency. A buffer layer 1222 is further provided on the surface of the heat sink 1223, which can prevent the heat dissipated by the battery 1221 from being directly conducted to the screen 110, thereby affecting the service life and display effect of the screen 110. Preferably, the buffer layer 1222 can use GELUSPOR foam, and the heat sink 1223 can be selected as a graphene patch. In addition, since electronic components also need to be fixed on the surface of the PCB board 123, the overall thickness of the power supply component 122 needs to be higher than the thickness of the PCB board 123. Among them, the thickness of the battery 1221 is the thickest among the battery 1221, the buffer layer 1222, and the heat sink 1223.

[0044] In an alternative embodiment, a charging port 129 is further provided on the metal middle frame 120. The charging port 129 is used to supply power to the navigation screen 100 by using an external device. In this embodiment, please refer to Figure 2 , the charging port 129 can be provided on the side wall of the metal middle frame 120. When the navigation screen 100 is removed from the base 200 or the electrical connection end 125 cannot supply power normally, the external device can be used through the charging port 129 to supply power to the navigation screen 100. Among them, the charging port 129 preferably can be selected as a Type-C charging port to improve the compatibility and universality of the charging port 129.

[0045] This embodiment also discloses a detachable central control system. Please refer to Figure 6 , Figure 6 is a schematic structural diagram of a detachable central control system disclosed in this embodiment. The detachable central control system 10 is used to be installed on the center console of an automobile to interact with the user. Among them, the detachable central control system 10 includes a base 200 and the navigation screen 100 described above. The base 200 is fixedly installed on the center console, and the navigation screen 100 is detachably connected to the base 200, and communication can be established between the navigation screen 100 and the base 200. That is to say, the detachable central control system 10 is a split structure, and the navigation screen 100 can be removed from the base 200, so that the size of the navigation screen 100 can be unrestricted and can be set to a larger size, thereby facilitating the user to use or operate. Moreover, after the user removes the navigation screen 100, the user can use or operate the navigation screen 100 at other positions (such as the rear seat, the co-pilot, etc.), thereby further improving the convenience of the user to operate the central control system.

[0046] In an alternative embodiment, please refer toFigure 4 , a magnetic attraction component 128 is further disposed in the accommodation cavity 121. The magnetic attraction component 128 is located on the side of the power supply component 122 away from the screen 110. A first magnet component is disposed on the base 200. When the navigation screen 100 is placed on the base 200, the position of the first magnet component corresponds to the position of the magnetic attraction component 128 to realize the connection between the navigation screen 100 and the base 200. In this embodiment, a preset distance is provided between the PCB board 123 and the magnetic attraction component 128. Separating the PCB board 123 from the magnetic attraction component 128 can prevent the magnetic field of the magnetic attraction from affecting the service life or normal use of the electronic components on the PCB board 123 during the magnetic attraction fixing process. In some embodiments, a groove for accommodating the magnetic attraction component 128 may be provided in the accommodation cavity 121 to fix the magnetic attraction component 128 in the accommodation cavity 121 by means of snap connection or the like, or the magnetic attraction component 128 may be fixed in the accommodation cavity 121 by means of gluing or the like. When the navigation screen 100 is placed on the base 200, the position of the first magnet component corresponds to that of the magnetic attraction component 128, and magnetic attraction is generated between the two, thereby fixing the navigation screen 100 on the base 200. In the specific implementation process, the first magnet component may be disposed inside the base 200 or outside the base 200. The first magnet component may be a magnet, and the number of magnets may be one or more. The method of supporting and magnetically fixing by the base 200 facilitates the user to pick up the navigation screen 100 on the premise of ensuring the connection stability between the navigation screen 100 and the base 200, thereby improving the use convenience of the detachable central control navigation system while ensuring the use safety.

[0047] In an alternative embodiment, please refer to Figure 4 , the magnetic attraction component 128 includes a magnetic attracting sheet. The magnetic attracting sheet and the PCB board 123 are arranged vertically, and the overlapping area of the projections of the magnetic attracting sheet and the PCB board 123 is minimized. That is to say, the magnetic attracting sheet and the PCB board 123 are arranged flatly rather than stacked, which can not only reduce the thickness of the navigation screen 100, but also prevent the magnetic field of the first magnet component from affecting the normal use or service life of the electronic components on the PCB board 123 when the magnetic attracting sheet cooperates with the first magnet component to achieve magnetic attraction. In this embodiment, preferably, the overlapping area of the projections of the magnetic attracting sheet and the PCB board 123 is 0, that is, they do not overlap on any plane in the Cartesian coordinate system. The magnetic attracting sheet itself does not have magnetic attraction ability, but can cooperate with the first magnet component to achieve magnetic attraction. Preferably, the magnetic attracting sheet may be an iron sheet. Among them, the number of magnetic attracting sheets may be multiple, and the shapes of the multiple magnetic attracting sheets may be different. When the number of magnetic attracting sheets is set to be multiple, preferably, the multiple magnetic attracting sheets are symmetrically arranged in the accommodation cavity 121 of the metal middle frame 120, so as to ensure that the navigation screen 100 can be evenly magnetically attracted and fixed, improving the fixing effect and stability.

[0048] In an alternative embodiment, the first magnet assembly includes at least two magnets, and the polarities of adjacent magnets among the at least two magnets are opposite. To improve the magnetic attraction effect, the first magnet assembly includes at least two magnets, for example, it can be four magnets, and the polarities of adjacent magnets among the multiple magnets are opposite, that is, the magnets with N-pole polarity and the magnets with S-pole polarity are arranged alternately, so as to improve the magnetic attraction force, and further improve the fixing effect and connection stability between the navigation screen 100 and the base 200, ensuring the use safety.

[0049] According to a navigation screen and a detachable central control system disclosed in an embodiment of the present invention, the navigation screen includes a screen, a metal middle frame, and a glass back plate. The screen and the glass back plate are respectively fixedly arranged on both sides of the metal middle frame. The metal middle frame has a flat accommodation cavity for arranging a power supply assembly, a PCB board, a wiring groove, and an electrical connector. The PCB board is electrically connected to the power supply assembly. The wiring groove is a groove on the inner side wall of the accommodation cavity, and a signal transmission FPC is arranged in the wiring groove. The signal transmission FPC is used to connect the PCB board and the central console. One end of the signal transmission FPC is connected to the PCB board, and the other end is connected to the central console through the electrical connector to achieve the electrical connection between the navigation screen and the central console. Through the above solution, a groove is arranged on the inner side wall of the accommodation cavity as the wiring groove, and the signal transmission FPC is placed in the wiring groove, which can protect the signal transmission FPC through the wiring groove, making the interface between the signal transmission FPC, the PCB board, and the electrical connector more stable without dislocation, thus ensuring the use stability of the navigation screen, and also being able to reduce the thickness of the navigation screen, so as to reduce the thickness of the navigation screen while ensuring the use stability of the navigation screen and improving the aesthetic degree of the navigation screen.
