Description

Technical Field

[0001] This utility model relates to the field of Beidou-3 handheld device technology, specifically a charging device for Beidou-3 handheld devices. Background Technology

[0002] In modern technological applications, BeiDou-3 handheld devices play a crucial role in numerous fields such as field exploration, emergency rescue, and outdoor navigation due to their precise positioning and efficient communication capabilities. As their application scenarios continue to expand and deepen, battery life has become a key factor in ensuring their continuous and stable operation. Currently, to address the issue of replenishing power for BeiDou-3 handheld devices during use, clip-on power banks have gained widespread market acceptance due to their convenient usage.

[0003] However, in practical use, the existing method of charging Beidou-3 handheld devices with clip-on power banks has shortcomings. Because charging devices generally lack effective heat dissipation structures, the heat generated during charging, as well as the heat generated by the handheld device itself, is difficult to dissipate effectively. Excessive overheating of the Beidou-3 handheld device can lead to a decline in the performance of its internal electronic components, thereby affecting the device's positioning accuracy and communication quality, and ultimately impacting the accuracy and efficiency of exploration work. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a charging device for Beidou-3 handheld devices.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A charging device for Beidou-3 handheld devices, including the handheld device body, has a socket at the bottom;

[0007] A clip-on charger with a plug at the bottom and a heat dissipation slot and air inlet on one side.

[0008] Heat dissipation components, including:

[0009] Several elastic thermal pads are arranged at equal intervals in the heat dissipation groove. Their outer side consists of a central contact surface and a pair of inclined surfaces located on both sides of the contact surface and facing away from each other.

[0010] Several baffles are respectively set on both sides of the corresponding elastic thermal pad to limit the deformation of the elastic thermal pad to both sides;

[0011] Several V-shaped fins, with their two sides respectively set on two opposite inclined surfaces, and airflow channels are formed between adjacent V-shaped fins and inside each V-shaped fin;

[0012] Several patches are respectively located on the outer side of the corresponding V-shaped fins and extend to the outside of the heat dissipation groove;

[0013] The cooling fan is located inside the air inlet, with its exhaust end facing the heat dissipation slot.

[0014] When the clip-on charger is attached to the back of the handheld device, the V-shaped fins adhere to the back of the handheld device, and the two side wings compress the elastic heat-conducting pad through the inclined surface, so that the contact surface deforms and protrudes to increase the contact area with the airflow.

[0015] Preferably, the contact surface is a concave arc surface, and its two sides smoothly transition to the side wing surfaces of the corresponding V-shaped fins.

[0016] Preferably, the inclination angle of the inclined plane is 40° to 50°.

[0017] Preferably, each of the V-shaped fins has a plurality of guide plates equidistantly arranged along the axial direction, and the side of the guide plate facing the air outlet of the cooling fan has an inclined surface.

[0018] Preferably, the elastic thermal pad is made of thermally conductive silicone, and the V-shaped fins, patches, and guide plates are all made of aluminum alloy.

[0019] Preferably, the air inlet is provided with a dust filter covering one of its openings, and the dust filter is located on the air intake side of the cooling fan.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The snap-fit ​​structure between the clip-on charger and the handheld device body, along with the V-shaped fins, elastic thermal pad, and cooling fan, forms a highly efficient heat dissipation system. During snap-fit, the V-shaped fins compress the thermal pad, causing the contact surface to deform and bulge. Combined with the baffle constraining the deformation direction, this enhances the tightness of the fit with the handheld device body to improve heat conduction efficiency and expands the contact area with the airflow. The V-shaped fins and the guide plate guide the airflow driven by the cooling fan to flow orderly within the channel. Combined with the patch extending outside the slot to enhance heat exchange, this significantly improves the heat dissipation effect. This effectively solves the heat generation problem during handheld device charging, improving device stability and lifespan. Attached Figure Description

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example

[0030] like Figures 1-5 As shown, the Beidou-3 handheld device charging device includes a handheld device body 1, which has a socket 10 at its bottom.

[0031] The back clip charger 2 has a plug 20 at the bottom. The plug 20 is inserted into the socket 10 to achieve charging. The back clip charger 2 has a heat dissipation groove 21 and an air inlet 22 on one side.

[0032] Heat dissipation component 3, which includes:

[0033] Several elastic thermal pads 30, made of thermally conductive silicone, are arranged equidistantly within the heat dissipation groove 21. The thermally conductive silicone material combines elasticity and thermal conductivity, which can adapt to the compression of the V-shaped fins 32 through deformation and also assist in heat transfer. Its outer side consists of a central contact surface 300 and a pair of opposite inclined surfaces 301 located on both sides of the contact surface 300. The contact surface 300 is a concave arc surface, and its two sides smoothly transition to the side wing surfaces of the corresponding V-shaped fins 32. The inclination angle of the inclined surfaces 301 is 40° to 50°. The inclined surfaces 301 provide compression guidance for the V-shaped fins 32 to ensure that the deformation direction is controllable.

[0034] Several baffles 31 are respectively disposed on both sides of the corresponding elastic thermal pad 30 to limit the deformation of the elastic thermal pad 30 to both sides. By constraining the deformation range, the deformation of the elastic thermal pad 30 is concentrated on the contact surface 300, thus ensuring the stability and effectiveness of the heat dissipation structure.

[0035] Several V-shaped fins 32 are provided with their two sides respectively on two opposite inclined surfaces 301, and airflow channels are formed between adjacent V-shaped fins 32 and inside each V-shaped fin 32; several guide plates 34 are provided equidistantly along the axial direction inside each V-shaped fin 32, and the side of the guide plate 34 facing the air outlet of the cooling fan 4 is provided with an inclined surface, which can guide the airflow to flow towards the back of the handheld device body 1, optimize the airflow direction, and improve the heat dissipation effect.

[0036] Several patches 33 are respectively disposed on the outer side of the corresponding V-shaped fins 32 and extend to the outside of the heat dissipation groove 21. When the back clip charger 2 is snapped into place on the back of the handheld device body 1, the patches 33 achieve close contact with the handheld device body 1 by squeezing the elastic thermal pad 30, thereby improving the heat conduction effect.

[0037] The V-shaped fins 32, the patch 33, and the guide plate 34 are all made of aluminum alloy. Aluminum alloy has high thermal conductivity and can quickly absorb the heat generated by the handheld device body 1.

[0038] The cooling fan 4 is located inside the air inlet 22, with its air outlet facing the heat dissipation slot 21. The air inlet 22 is equipped with a dust filter 40 covering one of its openings, and the dust filter 40 is located on the air intake side of the cooling fan 4. The cooling fan 4 actively draws in outside air to form an airflow, which accelerates the heat exchange in the heat dissipation slot 21. The dust filter 40 prevents dust from entering the equipment and avoids dust accumulation that affects heat dissipation and equipment lifespan.

[0039] When the clip-on charger 2 is attached to the back of the handheld device 1, the V-shaped fins 32 adhere to the back of the handheld device 1, and the two side wings compress the elastic heat-conducting pad 30 through the inclined surface 301, so that the contact surface 300 deforms and protrudes to increase the contact area with the airflow. The heat carried away by the airflow per unit time increases. In addition, the protruding contact surface 300 changes the airflow direction, so that the airflow forms a more complex turbulence in the heat dissipation groove 21, avoiding the increase of local thermal resistance caused by laminar flow and improving the heat exchange efficiency.

[0040] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
