Description

Technical Field

[0001] The utility model relates to the technical field of electric motorcycle central control screens, and in particular to an electric motorcycle central control screen with an air replenishing function. Background Art

[0002] Compared with four-wheeled cars and bicycles, two-wheeled electric vehicles (including common two-wheeled electric bicycles and electric motorcycles) are popular among people in cities due to their advantages such as low price, low cost of use, easy parking, labor saving and no traffic jams.

[0003] In order to display the relevant information parameters of the electric motorcycle operation, an electric motorcycle central control screen is usually installed in the center of the handlebar. The electric motorcycle central control screen can display data such as the vehicle speed, power level, steering sign, and headlight on sign, so that users can have a more intuitive understanding of the vehicle status and facilitate users to control the vehicle.

[0004] In order to achieve waterproof performance, the central control screen of electric motorcycles often adopts a sealed structure. This structure is not only waterproof, but also prevents external gas from entering. When the electric motorcycle is sent to a low-altitude area for use after leaving the factory, the air pressure outside the electric motorcycle central control screen is greater than the air pressure inside; or when the electric motorcycle is sent to a high-altitude area for use after leaving the factory, the air pressure outside the electric motorcycle central control screen is lower than the air pressure inside. It can be seen that during the use of electric motorcycles, the internal and external air pressures of the electric motorcycle central control screen are often unbalanced, and the atmospheric pressure will inevitably act on the central control screen; and the existing electric motorcycle central control screen uses a sealed structure and does not have an air replenishment function. The central control screen is subjected to atmospheric pressure for a long time, resulting in the risk of the central control screen being broken, reducing its service life. Utility Model Content

[0027] like Figure 1-6 As shown, an electric motorcycle central control screen with air replenishment function includes a front shell 1 and a rear cover 2. A display panel 3 is installed on the front end surface of the front shell 1. The display panel 3 is sealed and connected to the front shell 1. A display screen 4 and a circuit board 5 are arranged in the front shell 1. The display screen 4 is electrically connected to the circuit board 5. The circuit device and power supply of the electric motorcycle are electrically connected to the circuit board 5 respectively, so that the power supply of the electric motorcycle can supply power to the circuit board 5, and it is also convenient to control the electric motorcycle through the circuit board 5. The display screen 4 is attached to the display panel 3, and the position where the display panel 3 and the display screen 4 are attached is transparent glass, so that the user can view the content displayed on the display screen 4 through the light-transmitting display panel 3; the display screen 4 is used to display various working parameters of the electric motorcycle, including but not limited to displaying information such as power and speed. The rear cover 2 is covered on the periphery of the circuit board 5 and the display screen 4, and the rear cover 2 is sealed and connected to the front shell 1, so that the circuit board 5 and the display screen 4 are encapsulated by the front shell 1 and the rear cover 2. The back cover 2 is provided with an air-filling hole 21 which passes through the back cover 2. A waterproof breathable membrane 6 is provided at a position on the back cover 2 corresponding to the air-filling hole 21. The waterproof breathable membrane 6 is sealed with the back cover 2 and can block the air-filling hole 21. The waterproof breathable membrane 6 has the characteristic of preventing water from passing through but allowing air to pass through.

[0028] The electric motorcycle central control screen with air replenishment function is provided with an air replenishment hole 21 on the rear cover 2, and then a waterproof breathable membrane 6 is installed on the air replenishment hole 21, that is, the waterproof performance of the electric motorcycle central control screen is retained; at the same time, by providing the waterproof breathable membrane 6, the air in the rear cover 2 can circulate with the external air, so that the rear cover 2 can be air-replenished, which can be used to balance the pressure difference between the inside and outside of the electric motorcycle central control screen, avoid the problem of the electric motorcycle central control screen being broken due to the atmospheric pressure acting on the electric motorcycle central control screen, and extend the service life. Specifically, when the air pressure outside the electric motorcycle central control screen is greater than the air pressure inside, the external gas can enter the rear cover 2 through the waterproof breathable membrane 6, so as to balance the internal and external air pressures; when the air pressure outside the electric motorcycle central control screen is lower than the internal air pressure, the internal gas can flow out of the rear cover 2 through the waterproof breathable membrane 6, so as to balance the internal and external air pressures.

[0029] In this embodiment, the waterproof breathable membrane 6 is made of non-woven fabric material. In other embodiments, the waterproof breathable membrane 6 may also be made of other waterproof and breathable materials.

[0030] In the present embodiment, there are two air supply holes 21, and the two air supply holes 21 are symmetrically distributed along the center line of the rear cover 2, and each air supply hole 21 is respectively provided with a waterproof breathable membrane 6; by providing two air supply holes 21, the air supply efficiency can be improved, thereby accelerating the balance of the air pressure difference inside and outside the central control screen of the electric motorcycle.

[0031] A plug 22 is provided in the air-filling hole 21. In this embodiment, the plug 22 is integrally formed with the rear cover 2. In other embodiments, the plug 22 and the rear cover 2 may also be two separate parts. The plug 22 is used to block the air-filling hole 21, thereby reducing dust from entering the air-filling hole 21 and achieving a dust-proof effect. A plurality of lateral holes 23 are provided on the side wall of the plug 22, and the lateral holes 23 are connected to the inner cavity of the rear cover 2. By providing the lateral holes 23, the air-filling function can be retained. When the internal air pressure of the electric motorcycle central control screen is lower than the external air pressure, the external air can flow into the waterproof breathable membrane 6 through the lateral holes 23, and then pass through the waterproof breathable membrane 6 and flow into the interior of the rear cover 2, thereby balancing the internal and external air pressures of the electric motorcycle central control screen; and vice versa.

[0032] A light sensor 7 is installed on the front shell 1, and the light sensor 7 is electrically connected to the circuit board 5. The light sensor 7 is used to detect the current ambient brightness and feed back information to the circuit board 5. The circuit board 5 controls the brightness of the display screen 4 according to the ambient brightness, thereby improving the user experience and ensuring that the user can clearly see the content displayed on the display screen 4. A light-transmitting hole is provided at a position corresponding to the light sensor 7 on the front shell 1, and a light-transmitting portion 31 is provided at a position corresponding to the light sensor 7 on the display panel 3; external ambient light passes through the display panel 3 through the light-transmitting portion 31, and then passes through the light-transmitting hole to irradiate the light sensor 7, so that the light sensor 7 can monitor the current ambient brightness.

[0033] The circuit board 5 is provided with a plurality of indicator lights 8, including but not limited to: a turn indicator light, a gear indicator light, a lighting indicator light, a fault light, etc. Indicator icons 32 are respectively provided at positions corresponding to the indicator lights 8 on the display panel 3, and the light emitted by the indicator lights 8 can be irradiated onto the corresponding indicator icons 32; when the indicator lights 8 are on, the corresponding indicator icons 32 will be illuminated, and the user can obtain the corresponding information of the electric motorcycle by checking the indicator icons 32. For example: if the lighting indicator light is on, it means that the electric motorcycle has turned on the headlights, and if the left turn indicator light is on, it means that the electric motorcycle has turned on the left turn signal, and so on. By providing a plurality of indicator lights 8, the user can more intuitively obtain the corresponding information of the current electric motorcycle, thereby improving driving safety and enhancing user experience.

[0034] In order to make the indicator icon 32 more eye-catching, a hollow light guide column 11 is provided at the position corresponding to the indicator light 8 on the front shell 1. The hollow light guide column 11 is in a truncated cone shape, and the two ends of the hollow light guide column 11 are respectively connected to the display panel 3 and the circuit board 5. When the indicator light 8 is on, the light emitted by the indicator light 8 will shine into the hollow light guide column 11, and then shine on the indicator icon 32; the hollow light guide column 11 can play a certain focusing effect, thereby ensuring that most of the light can shine on the display panel 3, so that the indicator icon 32 can be more eye-catching, further improving driving safety and enhancing the user's use experience.

[0036] In order to improve the assembly efficiency, in the present embodiment, one end of the sealing ring 9 is provided with a chamfer 91; when installing the sealing ring 9 into the limiting groove 12, the end provided with the chamfer 91 can be facing downward, and then the sealing ring 9 can be inserted into the limiting groove 12, so that the sealing ring 9 can be quickly installed into the limiting groove 12, thereby improving the assembly efficiency of the sealing ring 9.

[0037] The front shell 1 and the back cover 2 are connected and fixed with connecting screws. In order to improve the sealing performance, a plurality of screw columns 13 are arranged on the front shell 1. Connecting screws are respectively arranged at positions corresponding to the screw columns 13 on the back cover 2. The connecting screws pass through the back cover 2 and are connected to the screw columns 13. The screw columns 13 are respectively sleeved with sealing gaskets 10, and the sealing gaskets 10 are respectively sealed against the inner side wall of the back cover 2. During assembly, each sealing gasket 10 is first sleeved on the screw column 13, and then the back cover 2 is placed on the front shell 1; then the connecting screws are tightened to push the back cover 2 closer to the front shell 1 until the inner side wall of the back cover 2 presses the sealing gasket 10; by installing the sealing gasket 10 on each screw column 13, the connection sealing performance between the front shell 1 and the back cover 2 is improved to ensure that it can achieve waterproofing.

[0038] The electric motorcycle central control screen with air replenishment function has a lateral hole 23 on the plug 22 and a waterproof breathable membrane 6 on the rear cover 2, so that it not only retains the basic waterproof performance, but also can balance the air pressure difference inside and outside the electric motorcycle central control screen, achieve air replenishment, avoid the problem of screen breakage caused by air pressure difference, and extend the service life. By setting a light sensor 7, the electric motorcycle central control screen can adjust the brightness of the display screen 4 according to the brightness of the environment, thereby improving driving safety and user experience.
