Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted equipment, and in particular to a detachable central control navigation system. Background Art

[0002] At present, car navigation has been widely used in cars. The existing car navigation screen is basically an integrated design with the car's center console, that is, a screen is installed on the center console, and car navigation is achieved with the help of the screen.

[0003] This design fixes the navigation screen to the center console. When users need to operate the screen, they can only operate it in a fixed position, which is not very convenient. For convenient navigation, users may turn to mobile navigation software, but the screen size of the mobile phone is smaller than that of the navigation screen, which will affect the user experience and driving safety. In addition, the integration of the navigation screen and the center console also limits the size of the navigation screen to the size of the car's center console. If other function buttons are required on the center console, the size of the navigation screen will also be smaller, thus reducing the user experience.

[0004] Therefore, providing a central control navigation system to improve the convenience of user operation has become a technical problem that needs to be solved urgently. Summary of the Invention

[0033] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0034] In order to improve the convenience of users in operating the central control navigation system, this embodiment discloses a detachable central control navigation system. Figure 1 , Figure 1 The following is a schematic diagram of the structure of a detachable central control and navigation system disclosed in this embodiment. The detachable central control and navigation system 10 is used to be installed on the dashboard of a car to interact with the user. The data interaction with the user can, for example, be based on the user's instructions to perform car control, driving navigation, and other operations. The detachable central control and navigation system 10 includes a central control screen 100 and a base 200. The central control screen 100 and the base 200 can communicate and transmit signals. The base 200 is fixedly mounted on the car dashboard, and the central control screen 100 and the base 200 are detachably connected. In other words, the detachable central control and navigation system 10 has a split structure. The central control screen 100 can be removed from the base 200, so that the size of the central control screen 100 is not limited and can be set to a larger size, making it easier for the user to use or operate it. In addition, the user can remove the central control screen 100 and use or operate the central control screen 100 in other locations (such as the back seat, the front passenger seat, etc.), further improving the user's convenience in operating the central control and navigation system.

[0035] Please refer to Figure 2 , Figure 2 This is a structural schematic diagram of a central control screen of a detachable central control navigation system disclosed in this embodiment. The central control screen 100 includes a screen 110, a metal middle frame 120, and a glass back panel 130, which are stacked and fastened in sequence. In this embodiment, the screen 110 and the glass back panel 130 are fixedly arranged on the front and rear sides of the metal middle frame 120, respectively. Among them, the material of the metal middle frame 120 is preferably aluminum or an aluminum alloy product. In this embodiment, the glass back panel 130 made of glass can reduce signal shielding and signal interference compared to the metal back panel conventionally used in the magnetic attraction field in the prior art, thereby ensuring the communication quality between the central control screen 100 and the base 200.

[0036] Please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of a metal middle frame of a detachable central control navigation system disclosed in this embodiment in one direction. Figure 4 This is a schematic diagram of the structure of the metal middle frame of a detachable central control navigation system disclosed in this embodiment in another direction. The metal middle frame 120 is formed by a semi-enclosed structure to form a flat accommodating cavity, which is used to set the battery assembly 121, PCB board 122 and magnetic assembly 123. Among them, the battery assembly 121 and PCB board 122 are arranged flat in the accommodating cavity, refer to Figure 3In terms of the direction in the center, the battery assembly 121 and the PCB board 122 are arranged up and down. The accommodating cavity is set to a flat shape, that is, a flat shape, which can reduce the thickness of the central control screen 100, and the battery assembly 121 and the PCB board 122 are arranged flat in the accommodating cavity, which can better utilize the accommodating space in the accommodating cavity, so that the accommodating cavity can accommodate the components of the central control screen 100 with a smaller depth, that is, the thickness of the accommodating cavity can be reduced, thereby further reducing the thickness of the central control screen 100. The magnetic component 123 is located on the side of the battery assembly 121 away from the screen 110, that is, the magnetic component 123 is located on the back of the battery assembly 121. In addition, the PCB board 122 is spaced a preset distance from the battery assembly 121 and the magnetic component 123 respectively. In this embodiment, the preset distance between the PCB board 122 and the battery assembly 121 is not necessarily the same as the preset distance between the PCB board 122 and the magnetic assembly 123. In other words, the PCB board 122 only needs to be separated from both the battery assembly 121 and the magnetic assembly 123. The specific separation distance can be set based on the actual layout requirements of the components within the accommodating cavity. Separating the PCB board 122 from the battery assembly 121 can prevent the PCB board 122 from being adversely affected by heating and deformation of the battery assembly 121 during use of the central control screen 100. Separating the PCB board 122 from the magnetic assembly 123 can also prevent the magnetic field from affecting the service life or normal use of the electronic components on the PCB board 122 during the magnetic attachment process. In some embodiments, a groove for accommodating the magnetic assembly 123 can be provided within the accommodating cavity, allowing the magnetic assembly 123 to be secured within the accommodating cavity by means such as snapping, or the magnetic assembly 123 can be secured within the accommodating cavity by means such as gluing.

[0037] Please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic structural diagram of a base of a detachable central control navigation system disclosed in this embodiment. Figure 6This is a schematic diagram of the partial structure of the base of a detachable central control navigation system disclosed in this embodiment. The base 200 includes a bracket 210, which is used to place the central control screen 100. A first magnet assembly 220 is provided on the base 200. When the central control screen 100 is placed on the bracket 210, the position of the first magnet assembly 220 corresponds to the position of the magnetic attraction assembly 123 to achieve the connection between the central control screen 100 and the base 200. In this embodiment, the bracket 210 can be an integrally formed structure with the base 200, or it can be a split structure, fastened by means of a snap or the like. When in use, the central control screen 100 is placed on the bracket 210. When the central control screen 100 is placed on the bracket 210, the position of the first magnet assembly 220 corresponds to the position of the magnetic attraction assembly 123, and magnetic attraction is generated between the two, thereby fixing the central control screen 100 on the base 200. In the specific implementation process, the first magnet assembly 220 can be set inside the base 200 or outside the base 200. The first magnet assembly 220 can be a magnet, and the number of magnets can be one or more. The bracket 210 supports and secures the central control screen 100 to the base 200 by magnetic attraction, ensuring the stability of the connection between the central control screen 100 and the base 200, and facilitating user access to the central control screen 100. This improves the ease of use of the detachable central control navigation system while ensuring safety.

[0038] In an optional embodiment, an anti-collision bar may also be provided on the bracket 210. The anti-collision bar is provided on the inner side of the bracket 210, that is, the side where the bracket 210 contacts the central control screen 100, and is used to reduce the friction between the bracket 210 and the central control screen 100, and to prevent the screen 110 of the central control screen 100 from being scratched by the bracket 210 when the central control screen 100 is placed on the bracket 210, thereby ensuring the service life of the screen 110.

[0039] In an optional embodiment, the base 200 further includes a housing and a fixing plate, the fixing plate being fixedly disposed inside the housing, and the first magnet assembly 220 being fixedly disposed on the fixing plate. In this embodiment, the fixing plate may be provided with a fixing position, and the first magnet assembly 220 is fixedly mounted in the fixing position.

[0040] In an optional embodiment, the magnetic attraction component 123 includes a first magnetic attraction component 1231, and the first magnetic attraction component 1231 is a magnetic attraction sheet. Figure 4In terms of the direction of the center, the magnetic attraction sheet and the PCB board 122 are arranged vertically, and the projected overlapping area of the magnetic attraction sheet and the PCB board 122 is minimized. In other words, the magnetic attraction sheet and the PCB board 122 are arranged flat rather than stacked. This not only reduces the thickness of the central control screen 100, but also prevents the magnetic field of the first magnet assembly 220 from affecting the normal use or service life of the electronic components on the PCB board 122 when the magnetic attraction sheet cooperates with the first magnet assembly 220 to achieve magnetic attraction. In this embodiment, it is preferred that the projected overlapping area of the magnetic attraction sheet and the PCB board 122 is 0, that is, the two do not overlap on any plane in the Cartesian coordinate system.

[0041] In this embodiment, the magnetic attraction sheet itself does not have magnetic attraction capability, but can cooperate with the first magnet assembly 220 to achieve magnetic attraction. Preferably, the magnetic attraction sheet can be an iron sheet. There can be multiple magnetic attraction sheets, and the shapes of the multiple magnetic attraction sheets can be different. When there are multiple magnetic attraction sheets, preferably, the multiple magnetic attraction sheets are symmetrically arranged in the accommodating cavity of the metal middle frame 120, so as to ensure that the central control screen 100 can be evenly fixed by the magnetic attraction force, thereby improving the fixing effect and stability.

[0042] In an optional embodiment, the magnetic component 123 includes a second magnetic component 1232, which is a magnet. The second magnetic component 1232 is arranged on the inner side wall of the side where the metal middle frame 120 contacts the bracket 210, and the bracket 210 is provided with a second magnet component 211 that cooperates with the second magnetic component 1232. In this embodiment, please refer to Figure 3 , both the second magnetic component 1232 and the second magnet component 211 can be magnets. When both are magnets, in order to ensure the quality of magnetic attraction, the polarity between the second magnetic component 1232 and the second magnet component 211 needs to be considered. The second magnetic component 1232 is arranged on the inner wall of the metal middle frame 120, and specifically can be arranged on the inner wall of the side where the metal middle frame 120 contacts the bracket 210. After the central control screen 100 is placed on the bracket 210, the magnetic attraction force between the second magnetic component 1232 and the second magnet component 211 can be used to fix the position of the central control screen 100. In addition, when the central control screen 100 is placed on the bracket 210, the magnetic attraction force between the second magnetic component 1232 and the second magnet component 211 can also play a certain role in limiting and guiding, so that the central control screen 100 can be placed in the correct position of the bracket 210. Preferably, there may be multiple second magnetic components 1232 , and the multiple second magnetic components 1232 are symmetrically arranged on the inner side walls of the metal middle frame 120 .

[0043] In an optional embodiment, the first magnet assembly 220 includes at least two magnets, and the polarities of adjacent magnets in the at least two magnets are opposite. Figure 6In order to improve the magnetic attraction effect, the first magnet assembly 220 includes at least two magnets, for example, four magnets, and the polarities of adjacent magnets in the multiple magnets are opposite, that is, magnets with N pole polarity and magnets with S pole polarity are arranged alternately, thereby increasing the magnetic attraction force, thereby improving the fixing effect and connection stability between the central control screen 100 and the base 200, and ensuring safe use.

[0044] In an optional embodiment, a positioning member 124 is further provided in the receiving cavity of the metal middle frame 120, and a Hall sensor is provided on the base 200. The Hall sensor and the positioning member 124 are arranged relative to each other to detect the placement position of the central control screen 100 when the central control screen 100 is placed on the bracket 210. In this embodiment, please refer to Figure 3 , the positioning member 124 can be a magnet, and the relative arrangement of the Hall sensor and the positioning member 124 means that the positions of the Hall sensor and the positioning member 124 correspond, and can cooperate to generate corresponding signals. When the central control screen 100 is placed in the correct position on the bracket 210, the position of the positioning member 124 corresponds to the position of the Hall sensor, so that the Hall sensor generates an electrical signal. The cooperation between the Hall sensor and the positioning member 124 is used to determine whether the central control screen 100 is in place, and the position detection of the central control screen 100 is realized, thereby improving the safety of use. In the specific implementation process, the user can also be reminded to adjust the position of the central control screen 100 when the central control screen 100 is not in place. Preferably, the number of positioning members 124 can be multiple, and the multiple positioning members 124 are symmetrically arranged in the accommodating cavity of the metal middle frame 120. Correspondingly, the number of Hall sensors can also be multiple, and the multiple Hall sensors are symmetrically arranged on the base 200.

[0045] In an optional embodiment, an electrical connection terminal 125 is further provided in the receiving cavity of the metal middle frame 120, and a signal transmission circuit is arranged. One end of the signal transmission circuit is connected to the PCB board 122, and the other end of the signal transmission circuit is connected to the electrical connection terminal 125. A mating terminal 230 is provided on the base 200. When the central control screen 100 is placed on the bracket 210, the electrical connection terminal 125 and the mating terminal 230 cooperate to power the central control screen 100. In this embodiment, please refer to Figure 5 and Figure 6 A signal transmission circuit is arranged within the housing cavity of the metal middle frame 120. One end of the signal transmission circuit is connected to the PCB board 122, and the other end of the signal transmission circuit is connected to the electrical connection terminal 125. The electrical connection terminal can be a pogo pin, and the position of the mating terminal 230 also corresponds to the position of the electrical connection terminal 125. That is, when the central control screen 100 is correctly placed on the bracket 210, the electrical connection terminal 125 and the mating terminal 230 cooperate, and the signal transmission circuit arranged within the housing cavity of the metal middle frame 120 is used to power the central control screen 100. Preferably, the signal transmission circuit can be a flexible FPC.

[0046] In an optional embodiment, a wiring groove with a certain depth can be opened in the accommodating cavity, and the signal transmission circuit can be laid out in the wiring groove. Arranging the signal transmission circuit in the wiring groove can protect and fix the signal transmission circuit, so that the interfaces at both ends of the signal transmission circuit can be firmly connected to the PCB board 122 and the electrical connector 125 respectively, thereby ensuring the connection stability of the central control screen 100, and also ensuring the stability of use of the central control screen 100. In addition, a groove is opened in the accommodating cavity to lay out the signal transmission circuit, which also increases the accommodating space of the accommodating cavity, thereby reducing the depth of the accommodating cavity (that is, the thickness of the metal middle frame 120), thereby thinning the thickness of the central control screen 100 and improving the aesthetics of the central control screen 100.

[0047] In an optional embodiment, a wiring trough is provided on the rear side of the battery assembly 121. When the signal transmission circuit is arranged in the wiring trough, a preset distance is provided between the signal transmission circuit and the battery assembly 121. In this embodiment, the wiring trough is provided on the rear side of the battery assembly 121, and the signal transmission circuit is also provided on the rear side of the battery assembly 121, which makes it easier for workers to assemble parts. Since the battery assembly 121 will generate heat or expand and deform during the charging or discharging process, when the signal transmission circuit is arranged in the wiring trough, there is a certain distance between the signal transmission circuit and the battery assembly 121, which can protect the signal transmission circuit from being excessively interfered with by the heating of the battery assembly 121, thereby ensuring the signal transmission quality and service life of the signal transmission circuit.

[0048] In an optional embodiment, a charging port 126 is further provided on the metal middle frame 120, and the charging port 126 is used to power the central control screen 100 using an external charging device. Figure 3 The charging port 126 can be provided on the side wall of the metal middle frame 120. When the central control screen 100 is removed from the bracket 210 or the electrical connection terminal 125 fails to provide power, the central control screen 100 can be powered by an external charging device through the charging port 126. Preferably, the charging port 126 can be a Type-C charging port to improve its compatibility and universality.

[0049] In an optional embodiment, the battery assembly 121 includes a battery 1211, a buffer layer 1212 and a heat sink 1213. The battery 1211 is spaced apart from the PCB board 122. The heat sink 1213 is attached to the side of the battery 1211 close to the screen 110. The heat sink 1213 is attached to the buffer layer 1212. In this embodiment, please refer to Figure 7 , Figure 7This is a schematic diagram of the structure of a battery assembly disclosed in this embodiment. The battery assembly 121 includes a buffer layer 1212, a heat sink 1213 and a battery 1211, which are stacked in sequence. Since the battery 1211 generates heat during the charging or discharging process, the battery 1211 is separated from the PCB board 122 to avoid the battery 1211 from affecting the PCB board 122 due to heat or deformation. The heat sink 1213 is affixed to the surface of the battery 1211 to assist in the heat dissipation of the battery 1211 and improve the heat dissipation efficiency. The buffer layer 1212 is further provided on the surface of the heat sink 1213 to avoid the heat dissipated by the battery 1211 from being directly conducted to the screen 110, thereby affecting the service life and display effect of the screen 110. Preferably, the buffer layer 1212 can use Jeros foam, and the heat sink 1213 can use a graphene patch. In addition, since electronic components need to be fixed on the surface of the PCB board 122, the overall thickness of the battery assembly 121 needs to be higher than the thickness of the PCB board 122, among which the thickness of the battery 1211 is the thickest among the battery 1211, the buffer layer 1212 and the heat sink 1213.

[0050] In an optional embodiment, the height of the battery assembly 121 is higher than the height of the PCB 122. In this embodiment, since electronic components also need to be mounted on the PCB 122, the height of the battery assembly 121 can be slightly higher than the height of the PCB 122. Thus, after the electronic components are mounted on the PCB 122, the height of the battery assembly 121 can be substantially the same as or slightly higher than the height of the PCB with the electronic components mounted thereon, ensuring that there is no significant height difference within the accommodating cavity. This makes the structure of the screen 110 more stable after it is mounted on the metal middle frame 120, providing a certain degree of protection for the screen 110.

[0051] In an optional embodiment, a shockproof layer is provided between the battery assembly 121 and the PCB 122 and the screen 110. In this embodiment, the shockproof layer is preferably made of foam, which provides both cushioning and shockproofing. The shockproof layer may completely cover the battery assembly 121 and the PCB 122, or may not completely cover them. The amount of shockproof layer can also be selected based on actual conditions.

[0052] In an optional embodiment, functional components such as a speaker, a microphone, and a camera can also be set in the housing cavity of the metal middle frame 120 to facilitate user use. In this embodiment, the number of speakers can be multiple, and the multiple speakers are symmetrically arranged in the housing cavity of the metal middle frame 120.

[0053] The present invention also provides an automobile, comprising the detachable central control navigation system as described above.

[0054] According to the detachable central control navigation system disclosed in the embodiment of the present invention, the detachable central control navigation system is used to be installed on the dashboard of a car to interact with data with the user. The detachable central control navigation system includes a central control screen and a base, and the middle frame screen and the base can communicate with each other. The base is fixedly installed on the dashboard of the car, and the central control screen and the base are detachably connected. Wherein: the central control screen includes a screen, a metal middle frame and a glass back panel that are stacked and fastened in sequence. The metal middle frame is formed into a flat accommodating cavity by a semi-enclosed structure. The accommodating cavity is used to set a battery assembly, a PCB board and a magnetic assembly. The battery assembly and the PCB board are arranged flat in the accommodating cavity. The magnetic assembly is located on the side of the battery assembly away from the screen, and the PCB board is spaced a preset distance from the battery assembly and the magnetic assembly respectively. A bracket for placing the central control screen and a first magnet assembly are provided on the base. When the central control screen is placed on the bracket, the position of the first magnet assembly corresponds to the position of the magnetic assembly to achieve connection between the central control screen and the base. Through the above solution, the detachable central control navigation system is set to a split structure, the base is fixed on the dashboard, and the central control screen and the base are detachably connected by magnetic attraction, so that the user can take the central control screen off the dashboard to operate the central control screen, thereby improving the convenience of user operation.

[0055] It will be understood by those skilled in the art that, under the premise of no conflict, the above-mentioned preferred embodiments can be freely combined and superimposed. Among them, the flowcharts and block diagrams in the accompanying drawings illustrate the possible implementation architecture, functions and operations of the systems, methods and computer program products according to various embodiments of the present disclosure.
