[0046] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0048] See also Figures 1 to 9 The present invention provides a DAB radio, comprising:

[0049] The housing frame 10 is installed as the basic supporting structure of the DAB radio to ensure the stable installation of the entire structure of the DAB radio.

[0050] The top shell 20 is installed on the mounting frame 10 to protect the internal components from external interference, and together with the mounting frame 10 forms a receiving cavity 30 to provide accommodation space for the installation of internal components. A heat sink 40 is installed at one end of the receiving cavity 30 to effectively dissipate the heat generated during operation to ensure the stable operation of the radio. An operation panel integrated part 50 is detachably installed at the other end to facilitate user operation, and the detachable design facilitates subsequent disassembly, maintenance and upgrades.

[0051] A control circuit board 60, disposed within the accommodating cavity 30 and mounted on the mounting housing 10, serves as the core control unit of the DAB radio. Mounting brackets 70 are provided on either side of the control circuit board 60, one end of which is fixedly mounted on the mounting housing 10. The control circuit board 60 is electrically connected to the operation panel assembly 50 to ensure accurate transmission and processing of user operation commands.

[0052] The locking adjustment mechanism 80 is adjustably mounted on a side of the mounting bracket 70 away from the control circuit board 60. This layout design optimizes the overall spatial structure of the DAB radio. The mounting frame 10 is provided with a first avoidance through-hole 11 adapted to the actuating end of the locking adjustment mechanism 80, ensuring smooth operation of the locking adjustment mechanism 80 and meeting the requirements for quick disassembly and assembly of the DAB radio.

[0053] It should be noted that when performing maintenance or replacement of the DAB radio, the operation panel assembly 50 is first quickly removed from the DAB radio, and then the locking adjustment mechanism 80 is unlocked to quickly disconnect the DAB radio from the vehicle, thereby achieving rapid replacement.

[0054] In this example, see Figures 4 to 9 , the locking adjustment mechanism 80 includes:

[0055] The guide limit rod 81 has one end connected to the mounting bracket 70 and the other end connected to the mounting frame 10 .

[0056] The push plate 82 is mounted on the guide limit rod 81 and can move back and forth along the length direction of the guide limit rod 81. The design of the guide limit rod 81 ensures the linearity and stability of the movement of the push plate 82, and realizes flexible operation of locking and unlocking.

[0057] The locking column 821 is installed at one end of the push plate 82 away from the mounting bracket 70 and is adapted to the first avoidance through hole 11 to ensure stability during locking and smoothness during unlocking.

[0058] The elastic member 83 is installed on the guide limit rod 81. One end of the elastic member 83 abuts against the mounting bracket 70, and the other end abuts against the push plate 82. The elastic member 83 is used to provide locking and tightening stress for the locking column 821, effectively preventing the locking column 821 from being accidentally unlocked in the non-operating state.

[0059] The adjustment member 84 is the core operating component of the locking adjustment mechanism 80. It is a crank member that utilizes the principle of leverage to achieve effortless operation and improve user experience. Specifically, mounting protrusions 822 are symmetrically positioned on either side of the push plate 82. The side of the mounting protrusions 822 proximate to the mounting bracket 70 is provided with a first mounting bump 823. The side of the mounting bracket 70 protrudes with a second mounting bump 73 protruding from the side of the mounting bracket 70 proximate to the first mounting bump 823. The interaction between the first mounting bump 823 and the second mounting bump 73 provides precise positioning points for the rotational installation of the adjustment member 84. Among them, the adjusting member 84 includes a first operating handle 841 and a second operating handle 842 fixedly connected to the first operating handle 841. The first operating handle 841 and the second operating handle 842 are set at an obtuse angle. The end of the first operating handle 841 away from the second operating handle 842 is rotatably mounted on the first mounting protrusion 823, and the connection between the first operating handle 841 and the second operating handle 842 is rotatably mounted on the second mounting protrusion 73, ensuring the operating comfort of the adjusting member 84, as well as the stability and reliability during the rotation process.

[0060] See also Figure 7 and Figure 8 A first avoidance slot 824 is provided on the mounting protrusion 822, and the first mounting protrusion 823 is installed on the mounting protrusion 822 and is arranged on both sides of the first avoidance slot 824 symmetrically. This layout not only enhances the stability of the installation, but also ensures the balance of the operating mechanics. The end of the first operating handle 841 away from the second operating handle 842 is set between the two first mounting protrusions 823 and is rotatably connected to the first mounting protrusion 823 through the first rotating shaft 843. A mounting groove 731 is provided on the second mounting protrusion 73, and the connection between the first operating handle 841 and the second operating handle 842 is set on the mounting groove 731 and is rotatably connected to the second mounting protrusion 73 through the second rotating shaft 844.

[0061] It should be clear that the design of the first avoidance groove effectively ensures the layout optimization of the internal structure, avoids structural interference between the mounting protrusion 822 and the adjustment member 84, and ensures the normal operation of the locking adjustment function.

[0062] See also Figure 4 and Figure 5The ends of the two second operating handles 842, away from the first operating handle 841, are fixedly connected by a connecting crossbar 85. This design not only enhances the structural stability of the two second operating handles 842, ensuring synchronization and consistency during operation, but also optimizes the overall mechanical distribution, enhancing the durability and reliability of the radio. Furthermore, the presence of the connecting crossbar 85 facilitates two-handed operation, improving convenience and comfort.

[0063] Further, see Figure 1 、 Figure 3 and Figure 9 First elastic clips 12 are protruding from both sides of the end of the mounting frame 10 away from the heat sink 40. A first mounting slot 51 corresponding to the first elastic clips 12 is defined on the operation panel assembly 50. This simplifies the assembly and disassembly steps of the operation panel assembly 50 and significantly enhances the connection stability between the operation panel assembly 50 and the mounting frame 10. The first elastic clip 12 includes a first elastic arm 121 and a first hook 122 mounted on the first elastic arm 121. The end of the first elastic arm 121 away from the first hook 122 is fixedly connected to the mounting frame 10. A snap-fitting protrusion 55 corresponding to the first hook 122 is protruding from the end of the first mounting slot 51 away from the mounting frame 10. The first hook 122 is in an inverted trapezoidal shape. This design effectively prevents the operation panel assembly 50 from accidentally falling off during long-term use, further enhancing the stability and reliability of the connection. Furthermore, when maintenance and disassembly are required, the operation panel assembly 50 can be quickly disassembled by simply separating the first hook 122 from the snap-fitting protrusion 55.

[0064] To further optimize the structural strength and connection stability, a snap-in slot 13 is further provided at the end of the mounting frame 10 away from the heat sink 40. The snap-in slots 13 are symmetrically arranged on both sides of the first elastic clip 12. A second elastic clip 52 corresponding to the snap-in slot 13 is protruded from the end of the operation panel assembly 50 close to the mounting frame 10, thereby enhancing the diversity and redundancy of the connection, providing multiple installation force points, and further improving the stability of the connection. The second elastic clip 52 includes a second elastic arm 521 and a second hook 522. The second hook 522 is mounted on one end of the second elastic arm 521, and the other end of the second elastic arm 521 is fixedly connected to the operation panel assembly 50. It is worth noting that the second hook 522 is hemispherical. This shape design not only allows it to be smoothly snapped into the snap-in slot 13, but also allows for structural separation by simply pulling it out when disassembly is required. This is convenient to operate, improves the accuracy and firmness of the snap-in connection, and facilitates subsequent maintenance and replacement.

[0065] Operating handles 53 are rotatably mounted on both sides of one end of the operating panel integration 50 away from the heat sink 40. This design improves the user's operating convenience. When the DAB radio needs to be adjusted or repaired, the operating panel integration 50 can be easily disassembled to adjust the locking adjustment mechanism 80. A first avoidance groove 531 corresponding to the snap-on protrusion 55 is provided on the operating handle 53, ensuring that the operating handle 53 will not interfere with the snap-on protrusion 55 during rotation, thereby ensuring smooth operation of the structure and smooth operation.

[0066] For further information, see Figure 6 The operating handle 53 is a magnetic handle, and a corresponding magnetic plate 54 is mounted on the operation panel assembly 50. The magnetic plate 54 is used to magnetically secure the operating handle 53. This design incorporates magnetic technology, allowing the operating handle 53 to fit tightly against the magnetic plate 54 on the operation panel assembly 50 when closed, achieving a magnetically secured effect, ensuring a discreet installation and preventing accidental operation.

[0067] An operating groove 532 is further provided on one side of the operating handle 53 away from the first avoidance groove 531 , which is ergonomic and convenient for the user to move the operating handle 53 to disconnect the magnetic connection between the operating handle 53 and the magnetic plate 54 .

[0068] Also, see Figure 7 The mounting bracket 70 includes a first support plate 71 and a second support plate 72. The first support plate 71 is fixedly connected to the second support plate 72 and is vertically arranged, which enhances the stability of the mounting bracket 70. The first support plate 71 is fixedly mounted on the mounting frame 10, and the locking adjustment mechanism 80 is adjustably mounted on the second support plate 72.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
