Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle instruments, and particularly relates to a heat dissipation structure of a motorcycle instrument. Background Art

[0002] A motorcycle instrument is a dashboard installed on a motorcycle, which is used to display various states and information of the vehicle. It usually includes displaying the current speed of the vehicle, the engine speed, helping the driver master the working state of the engine and the gear shifting timing, displaying the remaining fuel quantity in the fuel tank, reminding the driver to refuel in time, recording the mileage traveled by the vehicle, and prompting the coolant temperature of the engine, turn signals, headlights, fault indicator lights, etc., for prompting the driver of the vehicle operation state and various fault information.

[0003] At present, the heat dissipation structure for motorcycle instruments usually uses ventilation holes for heat dissipation, and the heat dissipation effect of the ventilation holes depends on the flow of external air. Therefore, in a stationary state, such as when parking or driving at a low speed, its heat dissipation effect may be limited and cannot achieve the expected effect. Although some instruments use fan heat dissipation, the air inhaled by the fan contains dust and impurities. After long-term use, these dusts will accumulate in the air ducts of the fan and radiator, blocking the air ducts, resulting in blocked air circulation, reducing the heat dissipation efficiency, increasing the equipment temperature, and thus affecting the heat dissipation effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 As shown, a heat dissipation structure of a motorcycle instrument includes an instrument housing 1 and an instrument body 2 disposed inside the instrument housing 1. A positioning housing 3 for heat dissipation is provided at the bottom of the instrument housing 1. The positioning housing 3 is used to install the instrument body 2. Heat dissipation grooves 31 are formed on both sides of the positioning housing 3. The heat dissipation grooves 31 facilitate the diversion of external wind and the heat dissipation of the instrument body 2. Silent fans 32 are provided on both sides of the inner cavity of the positioning housing 3. Since the number of the silent fans 32 is four, it can not only improve the heat dissipation efficiency, but also reduce the noise generated during heat dissipation through the silent setting, thereby improving the comfort during riding. Positioning brackets 4 are disposed on both sides of the inner cavity of the instrument housing 1. Baffles 33 for blocking the heat dissipation grooves 31 are provided on both sides of the positioning housing 3. Since the angles of the baffles 33 are inclined, the situation where rainwater flows into the inner cavity of the positioning housing 3 through the heat dissipation grooves 31 can be reduced. Clasps 5 are fixedly connected to both sides of the positioning housing 3.

[0023] A temperature sensor 34 for detecting the temperature of the instrument body 2 is fixedly connected to one side of the silent fan 32. The temperature sensor 34 is electrically connected to the silent fan 32 and the instrument body 2. When it is detected that the temperature of the instrument body 2 exceeds the preset value, the silent fan 32 will be started accordingly. Then, the external wind is drawn into the positioning housing 3 through the heat dissipation grooves 31 by the four silent fans 32 to efficiently dissipate the heat of the instrument body 2. The front and rear sides of the silent fan 32 are detachably connected to the positioning housing 3 by screws. Since the silent fan 32 is connected by screws, the convenience of disassembly can be improved. An exhaust slot 6 is formed at the bottom of the inner cavity of the positioning housing 3. The exhaust slot 6 is arranged in a circular array. Since the exhaust slot 6 is formed at the bottom of the positioning housing 3, the air flow can be promoted to improve the heat dissipation effect. A clamping strip 35 for installing the baffle 33 is fixedly connected to one side of the baffle 33. Limit slots 36 for cooperating with the clamping strip 35 are formed on both sides of the positioning housing 3. Through the movable connection between the clamping strip 35 and the limit slots 36, the installation and disassembly of the baffle 33 are facilitated, and the baffle 33 can block a certain amount of rainwater.

[0024] The inner cavity of the positioning frame 4 is provided with a filter plate 41, and an opening for inserting the filter plate 41 is formed on one side of the positioning shell 3. The filter plate 41 facilitates the filtration of dust, and the opening formed on the positioning shell 3 also facilitates the removal of the filter plate 41. One side of the filter plate 41 is fixedly connected with a pull plate 42, and one side of the pull plate 42 is fixedly connected with an insertion block 43 for positioning. The pull plate 42 facilitates the extraction of the filter plate 41, and the insertion block 43 facilitates the positioning of the pull plate 42. The surface of the insertion block 43 is fixedly connected with an elastic piece 44 for clamping. A clamping groove 45 for cooperating with the insertion block 43 and the elastic piece 44 is formed on one side of the buckle 5. The elastic piece 44 is semi-circular and symmetrically fixed on the surface of the insertion block 43. A buckle groove 46 is formed on one side of the pull plate 42. Through the arrangement of the elastic piece 44, the stability of the insertion block 43 in the buckle groove 46 can be improved, thereby ensuring the stability of the installation of the filter plate 41.

[0025] Working principle: The temperature sensor 34 is electrically connected between the instrument body 2 and the silent fan 32. When it is detected that the temperature of the instrument body 2 exceeds the preset value, the silent fan 32 will be started accordingly. Then, the outside air is drawn into the positioning shell 3 through the heat dissipation slots 31 by the four silent fans 32 to efficiently dissipate the heat of the instrument body 2. The temperature sensor 34 is electrically connected between the instrument body 2 and the silent fan 32. When it is detected that the temperature of the instrument body 2 exceeds the preset value, the silent fan 32 will be started accordingly. Then, the outside air is drawn into the positioning shell 3 through the heat dissipation slots 31 by the four silent fans 32 to efficiently dissipate the heat of the instrument body 2. The silent fans 32 are all obliquely arranged and are all aligned with the bottom of the instrument body 2, so as to dissipate heat efficiently. When the user needs to disassemble the filter plate 41 for maintenance, first pull it through the buckle groove 46 in the pull plate 42, so that the pull plate 42 drives the insertion block 43 to make the elastic piece 44 be squeezed in the buckle groove 46, and then pull the pull plate 42 forcefully to take out the filter plate 41, achieving the effect of convenient cleaning of the filter plate 41.
