Description

Technical Field

[0001] This utility model belongs to the field of charging equipment technology, specifically relating to a centralized charging box for multiple walkie-talkies. Background Technology

[0002] A walkie-talkie is a two-way mobile communication tool. Walkie-talkies can make calls without any network support and without incurring call charges. They are suitable for relatively fixed and frequent communication situations. They consist of a casing, main unit, battery, belt clip, charging dock, and antenna. Walkie-talkies are terminal devices for trunked radio communication. They can be used not only as terminal devices for trunked radio communication but also as a professional wireless communication tool in mobile communication.

[0003] Walkie-talkies have a wide range of applications. For example, in the fire and rescue industry, walkie-talkies are generally used by on-site rescue personnel to ensure smooth and timely communication during rescue operations. To facilitate unified charging management of walkie-talkies, ensure timely and quick charging, and make it convenient for users to use their assigned walkie-talkies, centralized charging boxes are usually used. However, existing centralized charging boxes for walkie-talkies tend to generate heat in both the power supply module and the charging area during charging. Due to the structure of the charging box, the heat is not easily dissipated, resulting in poor overall heat dissipation of the device and affecting its use. Utility Model Content

[0004] The purpose of this invention is to provide a centralized charging box for multiple walkie-talkies, which facilitates the dissipation of heat generated during charging and improves the heat dissipation effect of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A centralized charging box for multiple walkie-talkies includes: a box body, a cover plate hinged to the top of the box body, a mounting block fixedly installed inside the box body, a mounting groove provided on the mounting block, a power module installed in the mounting groove, a heat dissipation mechanism provided on the power module, a charging component provided on the mounting block, and a dustproof component provided above the charging component.

[0007] The heat dissipation mechanism includes a heat dissipation cavity formed at the bottom of the mounting slot. A heat-conducting plate is provided on the outside of the power module. The heat-conducting plate is fixedly installed inside the mounting slot. A heat sink is fixedly installed at the bottom of the heat-conducting plate. The bottom of the heat sink is inserted into the heat dissipation cavity through the mounting slot. An air inlet assembly is provided on the heat dissipation cavity.

[0008] Preferably, the air intake assembly includes multiple air intake slots formed on the heat dissipation cavity, and a blower is fixedly installed in the air intake slots.

[0009] Preferably, the housing has a ventilation opening, the position of which is adapted to the position of the blower, and a dustproof net is fixedly installed inside the ventilation opening.

[0010] Preferably, the charging assembly includes a plurality of charging slots formed on the top of the mounting block, wherein a charging base is disposed in the charging slot, and the power module and the charging base are electrically connected.

[0011] Preferably, the bottom of the multiple charging slots is provided with ventilation chambers, multiple ventilation slots are provided between the ventilation chambers and the heat dissipation chambers, and an air outlet component is provided at the top of the ventilation chambers.

[0012] Preferably, the air outlet assembly includes multiple air outlet channels disposed at the top of the ventilation cavity, and the top of each air outlet channel is provided with an air outlet that is inclined downwards. The air outlet is disposed in the charging slot and the air outlet direction is aligned with the charging base.

[0013] Preferably, the dustproof component includes a dustproof plate that is slidably disposed above the charging slot, the top of the mounting block is provided with a sliding groove that matches the dustproof plate, and the top of the dustproof plate is provided with a protrusion.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By using a heat-conducting plate, heat sink and blower, the heat generated by the power module is introduced into the heat dissipation cavity, and then the blower blows air to carry the heat out from the heat sink to dissipate heat from the power module. At the same time, the air is rapidly circulated by the use of ventilation slots, ventilation cavity, air outlet channel and air outlet. When the air is discharged through the air outlet, it blows towards the charging base to dissipate heat from the charging point, thereby improving the overall heat dissipation effect of the device and making it convenient to use.

[0016] (2) By setting up the dustproof plate, the opening of the charging slot is closed when the charging slot is not in use, so as to prevent dust from falling on the charging base. At the same time, the dustproof plate also protects the charging base from objects falling into the charging slot and causing damage to the charging base. Furthermore, by setting up the dustproof net, dust is prevented from entering the heat dissipation cavity when the blower is dissipating heat. Attached Figure Description

[0022] 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.

[0023] Example 1:

[0024] Please see Figures 1-4 As shown, a centralized charging box for multiple walkie-talkies includes: a box body 1, a cover plate 2 hinged to the top of the box body 1, and a connecting buckle (not shown in the figure) between the cover plate 2 and the box body 1. The connecting buckle facilitates the opening and closing of the box body 1, thereby making the charging box easy to carry and use. An installation block 3 is fixedly installed inside the box body 1. An installation groove 4 is opened on the installation block 3. A power module 6 is installed in the installation groove 4. The power module 6 is provided with an interface for connecting wires (not shown in the figure). The power module 6 is prior art and will not be described in detail here. The power module 6 is provided with a heat dissipation mechanism. A charging component is provided on the installation block 3. A dustproof component is provided above the charging component.

[0025] The heat dissipation mechanism includes a heat dissipation cavity 10 opened at the bottom of the mounting slot 4, a heat conduction plate 8 is provided on the outside of the power module 6, the heat conduction plate 8 is fixedly installed inside the mounting slot 4, a heat sink 9 is fixedly installed at the bottom of the heat conduction plate 8, the bottom of the heat sink 9 passes through the mounting slot 4 and is inserted into the heat dissipation cavity 10, and an air inlet component is provided on the heat dissipation cavity 10.

[0026] As can be seen from the above, the power module 6 supplies power to the charging component, which then charges the walkie-talkie. The heat is absorbed by the heat-conducting plate 8. The heat is conducted from the heat-conducting plate 8 to the heat dissipation cavity 10 through the heat sink 9. The air intake component causes the air in the heat dissipation cavity 10 to flow rapidly, thereby carrying away the heat on the heat sink 9. Through the combined use of the heat-conducting plate 8, the heat sink 9, and the air intake component, the power module 6 is cooled, preventing heat buildup during charging and avoiding damage to the power module 6.

[0027] The dustproof component allows for easy control of the opening and closing of the charging component, making it easy to turn it off when not in use and preventing dust from falling into the charging component and causing damage.

[0028] Specifically, regarding the aforementioned air intake components, please refer to... Figure 1 , Figure 2 and Figure 3 As shown, the air intake assembly includes multiple air intake slots formed on the heat dissipation cavity 10, and a blower 11 is fixedly installed in the air intake slots;

[0029] The enclosure 1 is provided with a ventilation opening, the position of which is adapted to the position of the blower 11. The ventilation opening facilitates the entry of air from outside the enclosure 1 into the enclosure 1, allowing air to circulate. A dustproof net 12 is fixedly installed inside the ventilation opening.

[0030] As can be seen from the above, the blower 11 is existing technology and will not be described in detail here. The blower 11 drives the air from outside the housing 1 into the heat dissipation cavity 10 through the ventilation port, so that the blower 11 drives the air to flow rapidly. During the air flow, the air comes into contact with the heat sink 9 and carries away the heat on the heat sink 9, thereby performing heat dissipation. The dustproof net 12 is used to intercept dust in the air and prevent dust from entering the housing 1.

[0031] Specifically, regarding the aforementioned charging components, please refer to... Figure 2 , Figure 3 and Figure 4 As shown, the charging component includes multiple charging slots 5 formed on the top of the mounting block 3, and a charging base 7 is provided in the charging slot 5. The power module 6 and the charging base 7 are electrically connected.

[0032] Multiple charging slots 5 have ventilation chambers 13 at their bottoms, and multiple ventilation slots 14 are provided between the ventilation chambers 13 and the heat dissipation chambers 10. An air outlet assembly is provided at the top of the ventilation chambers 13.

[0033] The air outlet assembly includes multiple air outlet channels 15 disposed at the top of the ventilation cavity 13. The top of the air outlet channel 15 is provided with an air outlet 16 that is inclined downward. The air outlet 16 is disposed in the charging slot 5 and the air outlet direction is aligned with the charging base 7.

[0034] As can be seen from the above, the charging dock 7 is existing technology and will not be described in detail here. There are multiple charging docks 7, and the charging docks 7 are set for different models, so that the charging docks 7 can charge different models of walkie-talkies and improve the applicability of the device.

[0035] The connection between the ventilation slot 14 and the ventilation cavity 13 facilitates the blower 11 to deliver air into the ventilation cavity 13, which then flows upward through the air outlet 15 and is discharged through the air outlet 16. The air outlet 16 is angled towards the charging base 7, allowing air to blow onto the charging base 7. This facilitates heat dissipation at the charging connection point while the walkie-talkie is charging, preventing heat from being difficult to dissipate and causing damage to the charging base 7 and the walkie-talkie. The blower 11 dissipates heat from both the power module 6 and the charging connection point, improving the device's heat dissipation effect and making it more convenient to use.

[0036] Example 2:

[0037] refer to Figure 1 and Figure 2 As shown, the dustproof assembly includes a dustproof plate 17 that is slidably disposed above the charging slot 5. The top of the mounting block 3 is provided with a sliding groove that is adapted to the dustproof plate 17, and the top of the dustproof plate 17 is provided with a protrusion.

[0038] As can be seen from the above, the bottom of the dustproof plate 17 is provided with a slider (not shown in the figure) that matches the sliding groove. The slider is set in the sliding groove. The use of the protrusion makes it easy to push the dustproof plate 17 to move. When the charging slot 5 needs to be used, the dustproof plate 17 is moved away from the center of the mounting block 3 by pushing the protrusion, so that the opening of the charging slot 5 is exposed, making it easy to put the walkie-talkie into the charging slot 5 and connect it to the charging base 7 for charging. When the charging is finished, the walkie-talkie is taken out, and the protrusion is pushed to move the dustproof plate 17 towards the center of the mounting block 3, so that the dustproof plate 17 is moved directly above the charging slot 5, closing the opening of the charging slot 5 and preventing dust from falling into the charging slot 5.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
