Description
Technical Field
[0001] This utility model relates to the technical field of radios, specifically a photovoltaic-powered radio with a locked speaker unit. 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] The speaker units of existing radios are often connected by snap-fit fasteners during installation. Since the snap-fit fasteners are movable, they lack auxiliary locking mechanisms and are prone to failure under shaking or direct external force, causing the speaker unit to dislodge. Utility Model Content
[0004] The purpose of this invention is to provide a photovoltaic-powered radio with a tightly locked speaker unit.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] The device includes a radio housing with a component slot. A panel is fitted onto the component slot and the component slot. The component slot houses a control circuit board, a rechargeable battery, and a speaker unit. The panel has control buttons. A telescopic antenna is mounted on the radio housing. A speaker opening is located on the side wall of the radio housing. The speaker unit is fixedly mounted on the inner wall of the radio housing and fitted into the speaker opening. A connecting plate is fixedly mounted on the outer edge of the speaker unit. Several connecting posts passing through the connecting plate are located on the inner wall of the radio housing. Each connecting post has a groove at its center along its length. The groove cuts off the connecting post along its length to form an elastic movable groove. A locking block that abuts against the connecting plate is fixedly mounted at the end of each connecting post. A locking post is inserted into the groove.
[0007] By adopting the above technical solution, when installing the speaker unit, press the speaker unit firmly to make the connecting post pass through the connecting plate. During the insertion process, the connecting post is squeezed and retracts towards the center through the connecting plate. After it is in place, the connecting post naturally unfolds and initially locks the connecting plate through the locking block. Then, the locking post is inserted. After the post groove is filled, the locking block at the end of the connecting post cannot approach and retract, and always maintains a good resistance to the connecting plate. The locking post effectively locks the connecting plate by suppressing the deformation of the connecting post itself, making the snap-fit structure of the speaker unit more secure and the installation more stable. When disassembling, pull out the locking post and pinch the end of the connecting post to simultaneously pull the connecting plate outward.
[0008] Furthermore, a threaded cylinder surrounding the locking post is fixedly provided on the outer wall of the connecting plate. The threaded cylinder is threadedly connected to a protective cylinder that covers the post groove. The locking post is slidably disposed through the protective cylinder. A retaining ring is fixedly provided on the outer edge of the end of the locking post that enters the protective cylinder. A pusher is fixedly provided on the end of the locking post that exits the protective cylinder.
[0009] By adopting the above technical solution, the threaded cylinder, in conjunction with the protective cylinder, effectively wraps around the connecting column. At the same time, the locking ring effectively restricts the range of motion of the locking column, preventing it from disengaging under external force. The pusher increases the contact area of the locking column, making it easier for the user to push or pull it out with their fingers. During installation, after the connecting column protrudes from the connecting plate, the protective cylinder is screwed into the threaded cylinder, and the pusher is pressed to allow the locking column to smoothly insert into the column groove, where it remains stationary due to friction. This achieves the effect of wrapping, protecting, and locking the connecting column.
[0010] Furthermore, the locking pin has a rounded corner at one end inserted into the pin slot, the outer edge of the protective cylinder is fixedly provided with several friction ridges, and the side wall of the radio housing is fixedly installed with a sound filter cotton layer that covers the horn.
[0011] By adopting the above technical solution, the rounded corners make the diameter of the locking pin end smaller than the pin groove, which facilitates smooth insertion. The setting of the friction ridge can effectively increase the surface friction of the protective cylinder, making it easier to twist. The sound filter cotton layer can effectively filter out noise and improve the sound effect of the speaker unit, and also has a good anti-collision effect to effectively protect the speaker unit.
[0012] Furthermore, an LED light group is fixedly installed on the outer wall of the radio housing, the panel is located on the top wall of the radio housing, and a photovoltaic panel and an LCD screen are embedded in the panel. The rechargeable battery, speaker unit, telescopic antenna, photovoltaic panel and LCD screen are electrically connected to the control circuit board.
[0013] By adopting the above technical solutions, LED light groups, in conjunction with photovoltaic panels and LCD screens, can supplement energy through sunlight on the one hand, and on the other hand, their functions are more diversified and their application range is wider.
[0014] 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.
[0015] In summary, the beneficial technical effects of this utility model are as follows:
[0016] 1. The design incorporates a connecting plate, connecting post, post groove, and locking post, which effectively locks the connecting plate by suppressing the deformation of the connecting post itself. This makes the snap-fit structure of the speaker unit more secure and the installation more stable.
[0017] 2. The use of a threaded cylinder, protective cylinder, locking ring, and pusher tab further optimizes the locking pin structure and improves the ease of operation of the locking pin;
[0018] 3. The locking pins are designed with rounded corners, which further optimizes the locking pin structure and facilitates smooth alignment with the pin slot for quick and accurate insertion. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] 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.
[0027] Please see Figure 1-4 The present invention provides the following technical solution:
[0028] The radio includes a housing 1, which has a component slot 101. A panel 2 is fitted onto the component slot 101. The component slot 101 houses a control circuit board 3, a rechargeable battery, and a speaker unit 4. The panel 2 has control buttons 5. A telescopic antenna 6 is mounted on the radio housing 1. A speaker opening 102 is provided on the side wall of the radio housing 1. The speaker unit 4 is fixedly mounted on the inner wall of the radio housing 1 and fitted into the speaker opening 102. A connecting plate 41 is fixedly provided on the outer edge of the speaker unit 4. Several connecting posts 42 are provided on the inner wall of the radio housing 1, passing through the connecting plate 41. A groove 421 is provided at the center of each connecting post 42 along its length. The groove 421 cuts off the connecting post 42 along its length to form an elastic movable groove 422. An abutment connection is fixedly provided at the end of each connecting post 42. The locking block 423 of plate 41 and the column groove 421 are equipped with locking pins 7. When installing the speaker unit 4, press the speaker unit 4 firmly to make the connecting pin 42 pass through the connecting plate 41. During the insertion process, the connecting pin 42 is squeezed and retracts towards the center through the connecting plate 41. After it is in place, the connecting pin 42 naturally unfolds and initially locks the connecting plate 41 through the locking block 423. Then the locking pin 7 is inserted. After the column groove 421 is filled, the locking block 423 at the end of the connecting pin 42 cannot approach and retract, and always maintains a good resistance to the connecting plate 41. The locking pin 7 effectively locks the connecting plate 41 by suppressing the deformation of the connecting pin 42 itself, making the buckling structure of the speaker unit 4 more secure and the installation more stable. When disassembling, pull out the locking pin 7 and pinch the end of the connecting pin 42 to simultaneously pull the connecting plate 41 outward.
[0029] A threaded cylinder 43 is fixedly installed on the outer wall of the connecting plate 41, surrounding the locking post 7. The threaded cylinder 43 is threadedly connected to a protective cylinder 71 that covers the post groove 421. The locking post 7 slides through the protective cylinder 71. A retaining ring 72 is fixedly installed on the outer edge of the end of the locking post 7 that enters the protective cylinder 71, and a pushing tab 73 is fixedly installed on the end of the locking post 7 that exits the protective cylinder 71. The threaded cylinder 43, in conjunction with the protective cylinder 71, effectively wraps around the connecting post 42. At the same time, the retaining ring 72 effectively restricts the range of motion of the locking post 7, preventing the locking post 7 from disengaging under external force. The pushing tab 73 increases the contact area of the locking post 7, making it easier for the user to push or pull it out with their fingers. During installation, after the connecting post 42 exits the connecting plate 41, the protective cylinder 71 is screwed into the threaded cylinder 43, and the pushing tab 73 is pressed to make the locking post 7 smoothly insert into the post groove 421, where it remains stationary due to friction. This achieves the effect of wrapping, protecting, and locking the connecting post 42.
[0030] The locking pin 7 has a rounded corner at one end inserted into the slot 421. Several friction ridges 74 are fixedly provided on the outer edge of the end of the protective cylinder 71. A sound-filtering cotton layer 8 covering the horn mouth 102 is fixedly installed on the side wall of the radio housing 1. The rounded corner makes the diameter of the end of the locking pin 7 smaller than that of the slot 421, which facilitates smooth insertion. The friction ridges 74 can effectively increase the surface friction of the protective cylinder 71, making it easier to twist. The sound-filtering cotton layer 8 can effectively filter out noise and improve the sound effect of the horn unit 4. On the other hand, it has a good anti-collision effect and effectively protects the horn unit 4.
[0031] An LED light group 9 is fixedly installed on the outer wall of the radio housing 1. The panel 2 is located on the top wall of the radio housing 1. The panel 2 is fitted with a photovoltaic panel 10 and an LCD screen 11. The rechargeable battery, speaker unit 4, telescopic antenna 6, photovoltaic panel 10 and LCD screen 11 are electrically connected to the control circuit board 3. The LED light group 9, together with the photovoltaic panel 10 and LCD screen 11, can supplement the energy through light, and the functions are more diversified and the application range is wider.
