[0021] This application proposes a vehicle navigation system; please refer to [reference needed]. Figures 1 to 4 The system includes a bottom cover 100, a display component 200, and a control component. The display component 200 and the control component are detachably connected to the bottom cover 100. The control component is located on one side of the display component 200 and includes a control panel 310 and an operating component 320. The operating component 320 is located on the control panel 310. The display component 200 includes a display screen 210 and a mounting component 220. The display screen 210 is configured to be flush with the control panel 310. The mounting component 220 is arranged on the back of the display screen 210 with four sides. The side of the mounting component 220 near the control panel protrudes from the edge of the display screen 210. A retaining component 120 is provided inside the bottom cover 100 and engages with the protruding edge of the mounting component 220.

[0022] The bottom cover 100 serves as the support and mounting base for the display screen 210, control components, etc. It adopts a trapezoidal structure that is wider at the top and narrower at the bottom, and has an opening 110. The opening 110 provides a mounting area for the display components and control components, while the interior of the bottom cover 100 accommodates other components. The bottom cover 100 can be made of various materials. In a preferred embodiment, the bottom cover 100 can be made of plastic.

[0023] In this embodiment, the one-piece molded front cover is eliminated. The opening 110, which was originally connected to the front cover, is used for the side-by-side installation of the display component and the control component. Please refer to... Figure 1 and Figure 2 After installation, the display screen 210 is flush with the control panel 310. The display screen 210 is no longer wrapped or squeezed by the inclined bezel, avoiding the closed gaps formed by the nested structure. This physically prevents dust from accumulating in dead corners. When cleaning the dust on the surface of the display screen 210, you only need to wipe the display screen 210 horizontally or vertically with a tissue or wet wipe. At the same time, it also improves the overall visual unity of the car navigation system, enhances its aesthetics, and avoids the operation lag caused by the height difference between the screen and the buttons in traditional navigation systems.

[0024] In this embodiment, the display component 200 can be detachably installed in various ways, such as by snap-fit ​​or bolt connection.

[0025] In this application embodiment, there are multiple options for the detachable installation method of the control component, such as snap-fit ​​or bolt connection.

[0026] The main function of the control component is to work in conjunction with the display screen 210 to achieve control interaction. Please refer to [link / reference needed]. Figure 1 It includes a control panel 310 and an operating component 320, with the operating component 320 disposed on the control panel 310. The control panel 310 can be disposed in various ways. In a preferred embodiment, the control panel 310 can also be detachably disposed at the opening 110 of the bottom cover 100, and located side-by-side on one side of the display screen 210.

[0027] In this embodiment, the type of the operating element 320 can be selected in various ways, such as a knob, a button, etc.

[0028] The material of the control panel 310 in this application embodiment can be selected from various options. In a preferred embodiment, the material of the control panel 310 can be plastic.

[0029] In this application embodiment, the display component 200 has several configuration options. In a preferred embodiment, please refer to... Figure 2 The display component 200 includes a display screen 210 and a mounting component 220.

[0030] Among them, the display screen 210 is a touch display screen 210. When using the vehicle navigation system provided in this application embodiment, the user can not only interact through the physical operating component 320, but also directly touch the display screen 210 to interact, thereby improving the interactive experience.

[0031] The main function of the mounting component 220 is to allow the display screen 210 to be mounted on the bottom cover 100. In this embodiment, the mounting component 220 can be implemented in various ways. In a preferred embodiment, please refer to... Figure 3 The mounting component 220 is arranged on the back of the display screen 210 with four sides. The side of the mounting component 220 near the control panel protrudes from the edge of the display screen 210. A corresponding retaining component 120 is provided inside the bottom cover 100, and the retaining component 120 is engaged with the protruding side of the mounting component 220.

[0032] It can be understood that the mounting component 220 is "frame-like" wrapped around the back of the display screen 210, rather than a single or scattered protrusion, which can provide more balanced support for the display screen 210 from all sides.

[0033] Among them, the side of the mounting member 220 facing the control panel 310 protrudes from the edge of the display screen 210. The protruding part of the mounting member 220 is a "locking member", and the retaining member 120 is a "locking member". The retaining member 120 can hook the edge of the mounting member 220 to form a mechanical lock.

[0034] In this embodiment, the number of card holders 120 can be varied. In a preferred embodiment, please refer to... Figure 4 There are two retaining members 120, which are spaced apart inside the bottom cover 100. They can simultaneously hook the edge of the mounting member 220, improve connection stability, and ensure that the display screen 210 is effectively fixed on the bottom cover 100.

[0035] The vehicle navigation system of this application embodiment includes a bottom cover 100, a display component 200, and a control component. The display component 200 and the control component are detachably connected to the bottom cover 100 for easy installation and replacement. The control component is located on one side of the display component 200 and includes a control panel and an operating component. The operating component is disposed on the control panel for the user to manually control the vehicle navigation system. The display component 200 includes a display screen 210 and a mounting component 220. The mounting component 220 is disposed on the back of the display screen 210 with four sides. The side of the mounting component 220 near the control panel protrudes from the edge of the display screen 210. A retaining component 120 is disposed inside the bottom cover 100. The protruding side of the snap-fit ​​mounting piece 220 can fix the display screen 210 to the bottom cover 100. After the display screen 210 is installed and fixed, it is configured to be flush with the control panel 310. The display screen 210 is no longer wrapped or squeezed by the inclined pressure frame, avoiding the closed gaps formed by the nested structure. This physically prevents the accumulation of dust in dead corner areas. When cleaning the dust on the surface of the display screen 210, you only need to wipe the display screen 210 horizontally or vertically with a paper towel or wet wipe. At the same time, it also improves the overall visual unity of the car navigation system and avoids the operation lag caused by the height difference between the screen and the buttons in traditional navigation systems, thus improving the interactive experience.

[0036] In this embodiment, the mounting member 220 has three other sides recessed into the edge of the display screen 210, forming steps that abut against the top surface of the side wall of the bottom cover 100. The support force from the top surface of the side wall of the bottom cover 100 against the steps ensures that the screen is stably mounted on the bottom cover 100, maintaining a flush position with the control panel. This prevents one side of the display screen 210 from tilting during vehicle vibrations, thus improving stability.

[0037] In this application embodiment, there are several options for the installation method of the control panel on the bottom cover 100. In a preferred embodiment, please refer to... Figure 5 The control panel extends toward the bottom cover 100 and forms a connecting block 315. The connecting block 315 has a positioning hole 3151 on one side wall of the inner side wall of the bottom cover 100. The inner side wall of the bottom cover 100 is provided with a positioning protrusion, which engages with the positioning hole 3151.

[0038] When installing the control components, first align the control panel with the opening of the bottom cover 100, insert the connecting block 315 along the edge of the opening 110, and when the positioning hole 3151 is positioned with the positioning protrusion, under the action of external force, the positioning protrusion is embedded in the positioning hole 3151 and engages with it, so that the control panel and the bottom cover 100 are stably connected, ensuring the stability of the vehicle navigation system.

[0039] In this application embodiment, the number of positioning protrusions can be selected in various ways. In a preferred embodiment, three positioning protrusions are provided, spaced apart on the inner sidewall of the bottom cover 100, and the number of positioning holes 3151 is correspondingly three, further improving the connection strength between the control panel and the bottom cover 100.

[0040] To further enhance the connection strength between the control panel and the bottom cover 100, please refer to... Figure 4 and Figure 5 The connecting block 315 extends toward the mounting member 220 to form two mounting portions 316, each mounting portion 316 having a mounting hole 3161, which is bolted to the bottom cover 100.

[0041] The bottom cover 100 has corresponding threaded holes. During installation, the mounting hole 3161 on the mounting part 316 is aligned with the threaded hole in the bottom cover 100. The bolt is passed through the mounting hole 3161 and screwed into the threaded hole to secure the mounting part 316 to the bottom cover 100, thereby stably mounting the control panel 310 onto the bottom cover 100. The mounting part 316 is located below the side of the mounting member 220 that protrudes from the screen, and the two abut against each other, providing support for the mounting member 220.

[0042] Please continue to refer to this. Figure 4 In this embodiment, a circuit board 400 is disposed inside the bottom cover 100. The circuit board 400 is located below the control panel 310, and the operating component 320 and the display screen 210 are connected to the circuit board 400. The circuit board 400, as a core control component, is fixed inside the bottom cover 100 and is located directly below the control panel 310, forming an upper and lower layer layout of "control panel 310-circuit board 400".

[0043] The circuit board 400 integrates various electronic components. The operating element 320 can trigger the electronic components by connecting to the circuit board 400, thereby realizing interactive control. The display screen 210 is electrically connected to the circuit board 400 and can be controlled by the circuit board 400 to display various information. At the same time, after receiving the trigger signal from the operating element 320, the circuit board 400 can control the information on the display screen 210 to change accordingly.

[0044] In this embodiment, the type of the operating element 320 can be selected in several ways. For example, please refer to... Figure 4 and Figure 6 The operating element 320 includes at least a knob 321, and the circuit board 400 is electrically connected to a rotary encoder 410. The knob 321 is connected to the rotary encoder 410.

[0045] In this application embodiment, the rotary encoder 410 can be of various types. In a preferred embodiment, the rotary encoder 410 is an EC11 rotary encoder. The EC11 rotary encoder generates signals through rotational motion to control the display screen 210. The EC11 encoder has five pins, two of which are similar to ordinary buttons, while the other three pins are used to detect the rotation direction of the knob 321. Therefore, the rotary encoder 410 of this application can output five different operation information under the control of the knob 321: pressed, forward rotation, reverse rotation, pressed forward rotation, and pressed reverse rotation. When playing music, the volume can be adjusted by rotating forward and reverse, and pressed to play or pause. For example, when viewing a navigation map, the map scale can be zoomed in or out by rotating forward and reverse.

[0046] In this application embodiment, there are several options for the connection configuration between the knob 321 and the rotary encoder 410. In a preferred embodiment, please refer to... Figure 5 and Figure 6 The control panel 310 has a first through hole 311 facing the rotary encoder 410. One end of the rotary encoder 410 is electrically connected to the circuit board 400, and the other end of the rotary encoder 410 passes through the first through hole 311 and is connected to the knob 321.

[0047] The rotary encoder 410 has a rotating shaft that passes through the first through hole 311 and is exposed outside the control panel 310. A knob 321 can be mounted on the rotating shaft and connected to the rotary encoder 410. The user can directly operate the knob 321 to drive the rotating shaft, thereby triggering the pin signals of the rotary encoder 410 to interactively control the display screen 210.

[0048] In the embodiments of this application, please refer to Figure 4 and Figure 6 The operating component 320 also includes at least one button 322, which is detachably mounted on the control panel 310. The circuit board 400 is electrically connected to at least one switching element 420. The button 322 can be moved to the trigger position under the action of external force to press and trigger the switching element 420. The button 322 is an independent component and is detachably mounted on the control panel 310 for easy replacement or maintenance.

[0049] The user presses button 322 on the control panel 310, causing button 322 to move downwards. When button 322 moves to the "trigger position", its bottom precisely presses against the switching element 420 on the circuit board 400, causing the contacts inside the switching element 420 to close or open, completing the switching of electrical signals, and enabling the vehicle navigation system to perform corresponding functions (such as confirming navigation commands or adjusting volume).

[0050] In this application embodiment, the type of switching element 420 can be selected from several options. In a preferred embodiment, the switching element 420 is a tactile switch.

[0051] In this embodiment, the number of buttons 322 can be multiple, such as 1, 2, or 3. In a preferred embodiment, please refer to... Figure 4 and Figure 6 There are three buttons 322, each capable of performing different controls. Correspondingly, the number of switching elements 420 matches that of the buttons 322.

[0052] In this application embodiment, the button 322 can be configured in several ways. In a preferred embodiment, please refer to... Figure 4 and Figure 5 The control panel 310 has at least one second through hole 312 corresponding to the button 322. The second through hole 312 is located on one side of the first through hole 311. The button 322 is inserted into the second through hole 312 and partially protrudes from the second through hole 312 for the user to press.

[0053] The second through hole 312 is provided on the control panel 310. Its shape matches the shape of the button 322. Its inner wall is provided with a guide groove and a limiting block to restrict the movement direction of the button 322 and prevent the button 322 from shifting laterally or falling off when pressed.

[0054] Button 322 is inserted into the second through hole 312. Its outer wall has a guide block and a limiting hole. The guide block is embedded in the guide groove of the second through hole 312, ensuring that button 322 can move axially along the hole. The limiting hole cooperates with the limiting block to limit the movement of button 322. Furthermore, a portion of button 322 (usually the pressing surface) protrudes from the surface of the second through hole 312. The protrusion height must be moderate to ensure that the user can clearly perceive the position of button 322 for easy blind operation, while avoiding excessive protrusion that could lead to accidental activation.

[0055] To facilitate user perception of the information displayed on button 322, different pattern information, such as commonly used patterns like "back" and "home," are provided on the pressing surface of button 322. The specific patterns can be determined according to actual needs, and this utility model does not impose any limitations on them.

[0056] It should be noted that when there are 3 buttons 322, there are also 3 second through holes 312, with intervals set on the control panel 310.

[0057] The vehicle navigation system in this embodiment can also provide emergency charging for mobile devices. Please refer to... Figure 5 and Figure 6The control panel 310 also has at least one third through hole 313, and the circuit board 400 is electrically connected to at least one TYPE-C interface 430 opposite to the third through hole 313. For example, mobile phones, mobile tablets, etc. can align the connector of the charging cable with the position of the third through hole 313 and insert it into the TYPE-C interface 430 for charging.

[0058] In this embodiment, the number of TYPE-C interfaces 430 can be set to multiple, such as two, and two corresponding third through holes 313 are provided. One TYPE-C interface 430 can be used to charge mobile devices, and the other TYPE-C interface 430 can be used by users to connect their mobile phones for data transmission, such as music playback.

[0059] The vehicle navigation system in this embodiment also has a voice control function. Please refer to [link / reference]. Figure 5 and Figure 6 The control panel 310 also has a fourth through hole 314, and the circuit board 400 is electrically connected to a microphone 440 opposite the fourth through hole 314. The microphone 440 is a microphone that can receive sound vibrations, convert them into electrical signals, and be recognized by the vehicle navigation system to execute corresponding controls.

[0060] In this embodiment, when the vehicle navigation system malfunctions or freezes, it can be manually reset. The control panel 310 also has a fifth through hole located above the first through hole 311. A reset element is electrically connected to the circuit board 400 corresponding to the fifth through hole, which can be pressed and triggered by the user to restart and reset the vehicle navigation system. The reset element can also be a tactile switch.

[0061] The above are only some or preferred embodiments of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
