Description

Technical Field

[0001] This utility model relates to the field of VHF radio equipment technology, and in particular to a vehicle-mounted split-type VHF radio equipment. Background Technology

[0002] The vehicle-mounted split-type VHF radio is a VHF communication device designed for mobile vehicle environments. Its core feature is the separate design of functional components such as the transmitting / receiving unit, control and display unit, and power module, which are connected via cables for separate installation. The transmitting / receiving unit (including the antenna interface) is typically fixed to the vehicle's trunk or chassis to save space, while the control and display unit is located in the driver's cabin for easy operation. The power module is compatible with the vehicle's power supply system. This device utilizes the 30-300MHz VHF band, supports short-range voice and data communication, and is widely used in traffic control, emergency rescue, and other fields, combining communication stability with the flexibility of vehicle installation.

[0003] However, existing VHF radio equipment is mostly fixed inside vehicles. To avoid occupying the operating area, the radio host is usually fixed in a concealed space such as the trunk, chassis, or under the driver's cab. Therefore, disassembly is difficult when maintenance is needed, which greatly reduces maintenance efficiency. At the same time, during vehicle operation, the bumps (especially during off-road driving and sudden braking) have a significant impact on core components (such as crystal oscillators, capacitors, and connectors), which can easily cause components to loosen, thus affecting the use of the equipment. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vehicle-mounted split-type VHF radio device includes a main unit housing and a mounting bracket. The mounting bracket has two mounting protrusions on its inner side. The main unit housing has mounting grooves on both sides, with the two mounting grooves respectively matching the corresponding mounting protrusions. The main unit housing has a component bracket on its inner side, and a radio component is mounted on the inner side of the component bracket. Two quick-release bases are fixedly mounted on one side of the mounting bracket. The top of each quick-release base has a sliding groove, and a limit slider is slidably mounted on the inner side of each sliding groove.

[0006] Specifically, aluminum heat sinks are fixedly installed on both the upper and lower sides of the main unit casing to enhance the heat dissipation effect of the device.

[0007] Specifically, each of the two quick-release bases has a fixed post on its top, and a crank is rotatably sleeved on the outside of each fixed post.

[0008] Specifically, both limit sliders have annular grooves at their tops, and grooves are formed on the inner and outer sides of the two annular grooves.

[0009] Specifically, limit posts are slidably installed on the inner sides of the two annular grooves. The two limit posts are adapted to the corresponding two grooves, and the two limit posts are rotatably connected to the corresponding cranks, which facilitates the limiting and fixing of the limit slider.

[0010] Specifically, a pressing post is fixedly installed on one side of each of the two limit sliders. One end of each pressing post abuts against the same main housing. A return spring is fixedly installed on the other side of each of the two limit sliders. The other end of each return spring is fixedly connected to the inner wall of the corresponding sliding groove, so that the return spring can quickly push the limit slider to reset when the main housing is disassembled.

[0011] Specifically, the bottom of each of the two quick-release bases is provided with an auxiliary groove, which is connected to the corresponding sliding groove. One side of each of the two limit sliders is provided with a guide protrusion, and a lifting clip is slidably fitted on each of the two guide protrusions. The bottom of the main unit housing is provided with two stabilizing grooves, and one end of each of the two lifting clips is adapted to the corresponding stabilizing groove to facilitate the fixing of the main unit housing.

[0012] Specifically, wedge blocks are fixedly installed at the bottom of both lifting clamps, and inclined metal blocks are fixedly installed on the inner side of both auxiliary slots. Wedge grooves are opened on the inclined surfaces of both inclined metal blocks, and the two wedge blocks are respectively matched with the corresponding wedge grooves.

[0013] Specifically, silicone shock-absorbing pads are fixedly installed on the outer side of the component bracket. The four silicone shock-absorbing pads are fixedly connected to the inner wall of the same host housing, and can quickly absorb high-frequency small-amplitude vibrations through the bending deformation of their molecular chains.

[0014] Specifically, multiple evenly distributed rubber springs are fixedly installed on the inner wall of the main unit housing. The other end of the multiple rubber springs is fixedly connected to the same component bracket. The concentrated force can be dispersed into radial tension by utilizing the deformation of the spiral structure, and some energy can be dissipated through the internal friction of the rubber material.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the lifting clamp can limit the main unit housing and fix it with the fixed bracket. When it needs to be disassembled and repaired, the main unit housing can be pushed in the direction of the limiting slider to squeeze it, thereby causing the lifting clamp to move down and release the limitation on the main unit housing, making it easy to disassemble. At the same time, the silicone shock-absorbing pad and rubber spring can effectively reduce and weaken the vibration during vehicle operation and prevent damage to the component bracket.

[0022] Reference Figure 1-5 A vehicle-mounted split-type ultra-shortwave radio device includes a main unit housing 1 and a fixed bracket 2. The fixed bracket 2 has two mounting protrusions on its inner side. The main unit housing 1 has mounting grooves on both sides, and the two mounting grooves are respectively adapted to the corresponding mounting protrusions. The main unit housing 1 has a component bracket 17 on its inner side, and the radio component is mounted on the inner side of the component bracket 17. Two quick-release bases 4 are fixedly installed on one side of the fixed bracket 2. The top of the two quick-release bases 4 has a sliding groove, and the inner side of the two sliding grooves is slidably installed with a limit slider 8.

[0023] In this embodiment, aluminum heat sinks 3 are fixedly installed on both the upper and lower sides of the main unit casing 1, which can enhance the heat dissipation effect of the device.

[0024] In this embodiment, a fixing post 5 is fixedly installed on the top of each of the two quick-release bases 4, and a crank 6 is rotatably sleeved on the outer side of each of the two fixing posts 5.

[0025] In this embodiment, annular grooves 9 are provided on the top of both limiting sliders 8, and grooves are provided on the inner and outer sides of both annular grooves 9.

[0026] In this embodiment, limit posts 7 are slidably installed on the inner sides of the two annular grooves 9. The two limit posts 7 are respectively adapted to the two corresponding grooves. The two limit posts 7 are respectively rotatably connected to the corresponding cranks 6, which facilitates the limiting and fixing of the limit slider 8.

[0027] In this embodiment, a pressing column 10 is fixedly installed on one side of each of the two limiting sliders 8. One end of each pressing column 10 abuts against the same main housing 1. A return spring 14 is fixedly installed on the other side of each of the two limiting sliders 8. The other end of each return spring 14 is fixedly connected to the inner wall of one side of the corresponding sliding groove, so that the return spring 14 can quickly push the limiting slider 8 to reset when the main housing 1 is disassembled.

[0028] In this embodiment, the bottom of each of the two quick-release bases 4 is provided with an auxiliary groove, and the two auxiliary grooves are respectively connected to the corresponding sliding grooves. One side of each of the two limiting sliders 8 is provided with a guide protrusion, and the lifting clips 11 are slidably sleeved on the two guide protrusions. The bottom of the main unit housing 1 is provided with two stabilizing grooves, and one end of each of the two lifting clips 11 is adapted to the corresponding stabilizing groove, so as to facilitate the fixing of the main unit housing 1.

[0029] In this embodiment, wedge blocks 12 are fixedly installed at the bottom of both lifting clamps 11, and inclined metal blocks 13 are fixedly installed on the inner side of both auxiliary slots. Wedge grooves are opened on the inclined surfaces of both inclined metal blocks 13, and the two wedge blocks 12 are respectively adapted to the corresponding wedge grooves.

[0030] In this embodiment, silicone shock-absorbing pads 15 are fixedly installed on the outer side of the component support 17. The four silicone shock-absorbing pads 15 are fixedly connected to the inner wall of the same main unit housing 1, and can quickly absorb high-frequency small-amplitude vibrations through the bending deformation of their molecular chains.

[0031] In this embodiment, multiple evenly distributed rubber springs 16 are fixedly installed on the inner wall of the main unit housing 1. The other end of the multiple rubber springs 16 is fixedly connected to the same component bracket 17. The concentrated force can be dispersed into radial tension by utilizing the deformation of the spiral structure, and some energy can be dissipated through the internal friction of the rubber material.

[0032] Working principle: During the installation of the radio main unit, the operator first installs the mounting bracket 2 in a concealed space such as the trunk, chassis, or under the driver's cab of the vehicle. Then, the mounting grooves on both sides of the main unit housing 1 are aligned with the corresponding mounting protrusions. The main unit housing 1 is then inserted into the mounting bracket 2, with one end of the main unit housing 1 inserted into the mounting bracket 2 contacting the two pressing posts 10. The operator then pushes the main unit housing 1 forcefully, pressing the two pressing posts 10. Under pressure, the two pressing posts 10 move the corresponding limiting sliders 8. The movement of the annular grooves 9 on the annular grooves 9 causes them to move. Both the inner and outer sides of the annular grooves 9 have grooves. When the annular grooves 9 move, the two limiting posts 7 slide out from the outer grooves. The tops of the two limiting posts 7 are rotatably connected to the corresponding cranks 6. The two cranks 6 are rotatably mounted on the corresponding fixed posts 5. Therefore, the movement distance of the two limiting posts 7 is limited; they can only move along the trajectory of the annular grooves 9 into the inner grooves. At this time, the position of the limiting sliders 8 shifts to the right. The movement of the two limiting sliders 8 causes the corresponding lifting clamps 11 to move to the right. The lifting clamps 11 move as they move... Simultaneously, it rises under the pressure of the inclined metal block 13. At this time, one end of each of the two lifting clamps 11 is inserted into the corresponding stabilizing groove, completing the installation and fixing. When disassembling the main unit housing 1, the main unit housing 1 is pushed, and the limiting post 7 slides out from the inner groove and moves to the outer groove with the annular groove 9. At this time, the return spring 14 rebounds and drives the limiting slider 8 to reset. The lifting clamps 11 move down under the action of the inclined metal block 13, disengaging from the stabilizing groove, completing the disassembly. When the main unit housing 1 is subjected to vibration or impact, the impact force is first transmitted to the silicone shock-absorbing pad 15, which is rapidly deformed by the bending of the molecular chain. The rubber spring 16 absorbs high-frequency, low-amplitude vibrations, reducing direct impact on the component support 17. If the impact intensity increases, the rubber spring 16 begins to compress, using the deformation of its spiral structure to disperse the concentrated force into radial tension. Some energy is dissipated through the internal friction of the rubber material. After the external force weakens, both components slowly reset due to elastic restoring force. The low hysteresis characteristic of the silicone damping pad 15 prevents the component support 17 from rebounding and oscillating. The rubber spring 16 suppresses secondary impacts during the reset process through gradual deformation, thereby weakening and mitigating the impact force and reducing its impact on the equipment.

[0033] The technological advancements of this invention compared to existing technologies are as follows: the main unit housing 1 can be limited and fixed in conjunction with the fixing bracket 2. When it needs to be disassembled and repaired, the main unit housing 1 can be pushed towards the limiting slider 8 to compress it, thereby causing the lifting clamp 11 to move down and release the limitation on the main unit housing 1, making it easy to disassemble. At the same time, the silicone shock-absorbing pad 15 and rubber spring 16 can effectively alleviate and weaken the vibration during vehicle operation and prevent damage to the component bracket 17.
