Description

Technical Field

[0001] This utility model relates to the technical field of radios, specifically to a multifunctional radio with a high-strength casing. Background Technology

[0002] A radio is a receiver for radio broadcasts. The weak, high-frequency modulated signal input through the receiving antenna is amplified, frequency-converted, and detected to recover the audio signal. Depending on the needs, radios can use different components and circuit configurations. Early radios used vacuum tubes, but now transistors and integrated circuits are commonly used. Simple reciprocating radios use only one transistor, while complex superheterodyne AM / FM radios often use multiple integrated circuits.

[0003] Existing radios generally use plastic casings with simple reinforcing strips on the inside as a basic means of reinforcement. However, the unsupported central area has low structural strength and is very easy to damage under external forces. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional radio with a high-strength casing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The radio housing includes a component compartment on its side wall, which houses a speaker unit and a control circuit board. Control buttons, a battery module, and a telescopic antenna are fixedly mounted on the outer wall of the radio housing. A protective panel covering the component compartment is fitted over the radio housing. The speaker unit is fitted to the protective panel, which has a speaker grille through its center. A mounting bracket is located on the inner side of the center of the protective panel. A fitting plate that mates with the mounting bracket is connected to the edge of the speaker unit. Several support columns extending from the radio housing surround the speaker unit and penetrate the fitting plate, abutting against the protective panel.

[0007] By adopting the above technical solution, the support column is arranged around the speaker unit in the central area. On the one hand, it can provide a good contact connection between the protective panel and the radio housing. When the central area is under stress, it can effectively transfer the force to the central area, avoiding uneven local stress and damage. On the other hand, the support column penetrates the interlocking plate to effectively fix the speaker unit. While providing a good support effect, it can also simultaneously fix the speaker unit, making the overall installation structure more stable.

[0008] Furthermore, the inner wall of the radio housing is provided with a support partition that cuts off the component compartment. The support partition cuts the component compartment laterally to form a circuit protection compartment. The circuit protection compartment is located at the top of the component compartment, and the control circuit board is fixedly installed in the circuit protection compartment.

[0009] By adopting the above technical solution, the support partition can not only effectively separate the component compartment, but also keep the control circuit board in the circuit protection compartment away from the vibration source while it is fixedly installed. Since the circuit protection compartment is separated from the component compartment, the overall structure is more compact and the shell deformation play is small, which has a significant effect on vibration suppression and effectively ensures the long-term stable operation of the control circuit board.

[0010] Furthermore, the protective panel extends along its edge with several connecting posts that abut against the inner wall of the radio housing. The radio housing is provided with locking bolts threaded through the connecting posts. Several horizontal and vertical reinforcing strips are fixedly provided on the inner sides of the radio housing and the protective panel. The reinforcing strips are fixedly connected to the outer edge of the connecting posts.

[0011] By adopting the above technical solution, the connecting post abuts against the radio casing, providing good support for the edges and facilitating installation. The outer edge of the connecting post is fixed with a reinforcing strip, which effectively improves the connection between the connecting post and the protective panel. At the same time, the mesh reinforcing strip can strengthen the overall structure of the radio from multiple angles without any blind spots. The combined effect greatly increases the overall structural strength of the radio.

[0012] Furthermore, the outer edge of the radio housing and protective panel is surrounded by a rubber anti-collision strip.

[0013] By adopting the above technical solution, the anti-collision strip effectively prevents the outer edge of the radio from directly colliding with the outside world, effectively buffering and protecting the overall structure.

[0014] Furthermore, a solar photovoltaic panel and an LED light panel are fixedly installed on the side wall of the radio housing, and the solar photovoltaic panel, LED light panel, speaker unit, control button, battery module and telescopic antenna are connected to the control circuit board.

[0015] By adopting the above technical solutions, the overall functionality of the radio has been further expanded, resulting in better adaptability to multiple fields.

[0016] Meanwhile, the panel also features a TF card slot, a USB port, a power indicator, an AUX input port, a power button, a charging indicator, and a DC 5V input port, all of which are connected to the circuit control board.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] 1. It adopts a protective panel, a fitting mounting bracket, a fitting plate, and a support column, which provides a good contact connection between the protective panel and the radio housing. When the central area is subjected to force, the force can be well transferred to the central area, avoiding uneven local stress and preventing damage.

[0019] 2. The use of support partitions and circuit protection chambers significantly reduces vibration and effectively ensures the long-term stable operation of the control circuit board.

[0020] 3. Rubber anti-collision strips are used to prevent the outer edge of the radio from directly colliding with the outside world, effectively buffering and protecting the overall structure. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 The present invention provides the following technical solution:

[0030] The radio housing 1 includes a component compartment 102 on its side wall, which houses a speaker unit 2 and a control circuit board 3. A control button 4, a battery module 5, and a telescopic antenna 6 are fixedly mounted on the outer wall of the radio housing 1. A protective panel 7 covers the component compartment 102. The speaker unit 2 is fitted to the protective panel 7. A speaker grille 71 is provided through the center of the protective panel 7. A mounting bracket 72 is provided on the inner side of the center of the protective panel 7. A fitting plate 21 is provided at the edge of the speaker unit 2 to cooperate with the mounting bracket 72. The radio housing 1 extends... Several support columns 101 surround the speaker unit 2. The support columns 101 penetrate the interlocking plate 21 and abut against the protective panel 7. The support columns 101 are arranged around the speaker unit 2 in the central area. On the one hand, they can provide a good contact connection between the protective panel 7 and the radio housing 1. When the central area is subjected to force, the force can be well transmitted to it, avoiding uneven local force in the central area and causing damage. On the other hand, the support columns 101 penetrate the interlocking plate 21 to effectively fix the speaker unit 2. While providing a good support effect, they can also play a role in simultaneously fixing the speaker unit 2, making the overall installation structure more stable.

[0031] The inner wall of the radio housing 1 is provided with a support partition 73 that cuts off the component compartment 102. The support partition 73 cuts the component compartment 102 horizontally to form a circuit protection compartment 74. The circuit protection compartment 74 is located on top of the component compartment 102. The control circuit board 3 is fixedly installed in the circuit protection compartment 74. The support partition 73 can not only effectively separate the component compartment 102, but also keep the control circuit board 3 in the circuit protection compartment 74 away from the vibration source while being fixedly installed. Since the circuit protection compartment 74 is separated from the component compartment 102, the overall structure is more compact and the housing deformation play is small. It has a significant vibration suppression effect at this point and effectively ensures the long-term stable operation of the control circuit board 3.

[0032] The protective panel 7 has several connecting posts 75 extending along its edge, which abut against the inner wall of the radio housing 1. The radio housing 1 is threaded through with locking bolts 76 that connect the connecting posts 75. Several horizontal and vertical reinforcing strips 8 are fixedly installed on the inner sides of the radio housing 1 and the protective panel 7. The connecting posts 75 are fixedly connected to the reinforcing strips 8 on their outer edges. The connecting posts 75 abut against the radio housing 1, providing good support for the edges and facilitating installation. The fixed connection of the connecting posts 75 to the reinforcing strips 8 effectively improves the connection between the connecting posts 75 and the protective panel 7. At the same time, the mesh-like reinforcing strips 8 can reinforce the overall structure of the radio from multiple angles without dead angles. The combined effect greatly increases the overall structural strength of the radio.

[0033] The outer edges of the radio housing 1 and the protective panel 7 are surrounded by rubber anti-collision strips 9. The anti-collision strips effectively prevent the outer edges of the radio from directly colliding with the outside world, effectively buffering and protecting the overall structure.

[0034] A solar photovoltaic panel 10 and an LED light panel 11 are fixedly installed on the side wall of the radio housing 1. The solar photovoltaic panel 10, LED light panel 11, speaker unit 2, control button 4, battery module 5 and telescopic antenna 6 are connected to the control circuit board 3, which further expands the overall functionality of the radio and has better adaptability to multiple fields.

[0035] Meanwhile, the panel also features a TF card slot, a USB port, a power indicator, an AUX input port, a power button, a charging indicator, and a DC 5V input port, all of which are connected to the circuit control board.
