[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The embodiment of the present invention provides a car logo, which can solve the problem in the related art that the temperature of the luminous car logo is too high and it is uncomfortable for human hands to touch.

[0039] See also Figure 1 and Figure 4 As shown, a car logo provided by an embodiment of the present invention may include: a mounting shell 1, the mounting shell 1 may include a heat dissipation device 12, and the heat dissipation device 12 may be arranged on the outside of the mounting shell 1; a lampshade 3, the lampshade 3 and the mounting shell 1 surround a receiving cavity 4; a circuit board 2, the circuit board 2 is arranged in the receiving cavity 4, and the circuit board 2 can be fitted with the heat dissipation device 12, and a light source 21 is provided on the circuit board 2, and the light source 21 can generate light that passes through the lampshade 3; the heat dissipation device 12 can guide the heat in the receiving cavity 4 to the air.

[0040] Similar to traditional logos, the car logo provided in this embodiment also generates light through the light source 21 on the circuit board 2, thereby improving the viewing effect of the logo. By installing the housing 1 and the lampshade 3 to form a receiving cavity 4, it is possible to reduce the contact between water vapor in the air and the inner wall of the lampshade 3, thereby reducing the risk of fogging of the lampshade 3. At the same time, since the housing 1 and the lampshade 3 form a receiving cavity 4, the heat generated by the light source 21 cannot be discharged in time, thereby causing the temperature of the lampshade 3 to be too high, which makes it uncomfortable for people to touch.

[0041] Different from the conventional logo, in this embodiment, by fitting the circuit board 2 with the heat sink 12 and arranging the heat sink 12 on the outside of the mounting shell 1, when the logo is mounted on the vehicle, the heat sink 12 can directly contact the outside air. Compared with the heat dissipation mechanism arranged inside the accommodating cavity 4, the heat sink 12 not only cools the circuit board 2 by contacting with the circuit board 2, but also can guide the heat to the outside air because it is arranged on the outside of the mounting shell 1, so as to avoid the temperature inside the accommodating cavity 4 from rising, and can guide the heat in the accommodating cavity 4 to the air through the heat sink 12. Specifically, the heat sink 12 can be a heat dissipation grille structure in this embodiment, and the heat of the logo is guided out through the temperature difference between the logo and the air. In other embodiments, the heat sink 12 can also be a water cooling or air cooling device to improve the heat dissipation effect and reduce the overall temperature of the logo. At the same time, because the heat sink 12 is arranged on the outside of the mounting shell 1, it will not occupy the space inside the accommodating cavity 4, simplifying the arrangement inside the accommodating cavity 4.

[0042] That is to say, by placing the circuit board 2 in the accommodating cavity 4 formed by the mounting housing 1 and the lampshade 3, it is possible to prevent water vapor from contacting the inner wall of the lampshade 3, reduce the fogging of the logo, and improve the texture of the vehicle logo. At the same time, because the circuit board 2 is attached to the heat dissipation device 12, the heat of the circuit board 2 can be directed to the outside, reducing the temperature of the circuit board 2 and the temperature of the accommodating cavity 4, thereby preventing discomfort caused by the logo being too hot when touched by a human hand.

[0043] See also Figure 2 and Figure 3 As shown, in some optional embodiments, the mounting shell 1 may include a mounting base 11 and a heat dissipation device 12; the heat dissipation device 12 may include a main board body 121 and a plurality of heat conducting plates 122, the main board body 121 is in contact with the circuit board 2, the heat conducting plates 122 are located on the side of the main board body 121 away from the circuit board 2, and the heat conducting plates 122 are arranged at intervals in the heat dissipation area of ​​the main board body 121; the mounting base 11 is provided with a through hole 118 corresponding to the heat dissipation area; the heat conducting plate 122 is inserted into the through hole 118 to direct the heat in the accommodating cavity 4 to the air.

[0044] That is to say, the heat dissipation device 12 dissipates heat through a plurality of heat conducting plates 122 arranged at intervals. In this embodiment, the heat conducting plates 122 are parallel to each other, and the heat dissipation device 12 is made of aluminum alloy with excellent heat conduction effect. In other embodiments, the heat conducting plates 122 on the main board body 121 can also be arranged staggeredly, and at the same time, the heat dissipation device 12 can also be made of materials with excellent heat conduction performance such as graphite and silica gel. Heat dissipation is achieved through the heat conducting plates 122 arranged at intervals. As the vehicle speed increases, the air flow rate for heat exchange with the heat conducting plates 122 becomes faster, and the heat dissipation effect of the heat dissipation device 12 is better. Moreover, it does not require external equipment, occupies a small space, and is convenient to arrange. As Figure 2 shown, the installation housing 1 is formed by assembling the mounting base 11 and the heat dissipation device 12. Generally, the outer shell of the logo is made of plastic material that is easier to shape. Compared with integrating the installation housing 1, the form of separately producing and then assembling the mounting base 11 and the heat dissipation device 12 has a lower cost and lower shaping difficulty. Since the mounting base 11 is provided with a through hole 118 corresponding to the heat dissipation area, the heat conducting plates 122 can extend out of the mounting base 11 to contact the air. Among them, in this embodiment, the mounting base 11 is provided with a through hole 118 through which all the heat conducting plates 122 can pass, which increases the contact area between the heat dissipation device 12 and the air. In other embodiments, the mounting base 11 can also be provided with through holes 118 having the same number as the heat conducting plates 122 to enable each heat conducting plate 122 to pass through a through hole 118, playing a protective role for the heat dissipation device 12, or through holes 118 fewer than the number of heat conducting plates 122 can also be provided on the mounting base 11.

[0045] See Figure 1 , Figure 3 , Figure 4 and Figure 6 shown, in some alternative embodiments, the edge of the main board body 121 can be provided with a flange 123, and the flange 123 can surround the main board body 121; the mounting base 11 can be provided with a fixing groove 112 corresponding to the flange 123; the flange 123 can be inserted into the fixing groove 112 to achieve a sealed connection between the heat dissipation device 12 and the mounting base 11.

[0046] That is to say, the annular flanging 123 is inserted into the corresponding annular fixing groove 112, so as to install the heat dissipation device 12 on the mounting base 11. Since the flanging 123 is provided and inserted into the fixing groove 112, the flanging 123 can block the water vapor from entering the accommodating cavity 4 from the connection part between the heat dissipation device 12 and the mounting base 11. Through the annular structure, it can be ensured that all connection positions are airtight connections, keeping the accommodating cavity 4 dry and reducing the fogging of the lamp cover 3. In this embodiment, the fixing groove 112 is a groove formed by a U-shaped thin wall, and structural adhesive will be pre-filled in the fixing groove 112 during the connection process to further ensure airtight connection and block the entry of water vapor. The connection between the two is realized by the insertion method, and positioning is achieved by using the fixing groove 112, ensuring the installation accuracy.

[0047] See Figure 2 and Figure 3 As shown, in some alternative embodiments, the mounting housing 1 may be provided with a ventilation hole 115 and a one-way ventilation membrane 116 that matches the ventilation hole 115; the one-way ventilation membrane 116 can block the external water vapor from entering the accommodating cavity 4 through the ventilation hole 115, and the water vapor in the accommodating cavity 4 can pass through the one-way ventilation membrane 116 and be discharged through the ventilation hole 115. That is to say, by providing the ventilation hole 115 on the mounting housing 1 to meet the air exchange needs between the accommodating cavity 4 and the outside air, and a one-way ventilation membrane 116 is provided at the ventilation hole 115 to prevent water vapor from entering the accommodating cavity 4 through the ventilation hole 115. To avoid fogging in the accommodating cavity 4. In this embodiment, a chip 22 is provided on the side of the circuit board 2 away from the lamp cover 3, and a shielding cover 23 is provided outside the chip 22 to prevent the chip 22 of the circuit board 2 from being electromagnetically interfered. At the same time, an avoidance groove 117 corresponding to the shielding cover 23 is provided on the mounting base 11 to avoid installation interference.

[0048] See Figure 2 and Figure 5 As shown, in some alternative embodiments, a drying packet 6 is provided in the accommodating cavity 4. The drying packet 6 is used to absorb the water vapor in the accommodating cavity 4, reduce the fogging of the logo, and can keep the inside of the accommodating cavity 4 dry for a long time.

[0049] See Figure 2 and Figure 5As shown, in some alternative embodiments, a light homogenizing housing 5 may be provided between the circuit board 2 and the lamp shade 3, and the light generated by the light source 21 passes through the light homogenizing housing 5 and shines on the lamp shade 3; the drying packet 6 may be disposed on a side of the light homogenizing housing 5 facing away from the circuit board 2. That is to say, by disposing the drying packet 6 between the light homogenizing housing 5 and the lamp shade 3, the water vapor on the surface of the lamp shade 3 can be better absorbed, reducing fog. By providing the light homogenizing housing 5 between the lamp shade 3 and the light source 21, the light generated by the light source 21 can be converted into a uniform surface light source, improving the illumination effect of the logo. In this embodiment, the light homogenizing housing 5 is milky white PC (Polycarbonate), and the light source 21 is an led dot matrix. The light homogenizing housing 5 can convert the point light source of the light source 21 into a surface light source, making the light irradiated on the lamp shade 3 soft and uniform. In this embodiment, the drying packet 6 is adhered to the light homogenizing housing 5. In other embodiments, a clamping mechanism may also be provided to clamp the drying packet 6. In this embodiment, the drying duration of the logo can be extended by replacing the drying packet 6.

[0050] See Figure 2 , Figure 3 and Figure 5 As shown, in some alternative embodiments, a light source area and a second area may be provided on a side of the circuit board 2 facing away from the mounting housing 1; the light source 21 is arranged in the light source area; the light homogenizing housing 5 includes an integrally formed fitting portion 52 and a light homogenizing cover body 51, the fitting portion 52 is fitted to the second area, and the light homogenizing cover body 51 covers the outside of the light source area; a limiting groove 53 is formed by the side wall of the light homogenizing cover body 51 and the fitting portion 52, and the drying packet 6 is located in the limiting groove 53. That is to say, the light source area where the light source 21 is distributed is covered by the light homogenizing cover body 51 to achieve a better illumination effect. By fitting the fitting portion 52 to the second area of the circuit board 2, the fitting portion 52 and the light homogenizing cover body 51 are formed to enclose the limiting groove 53, realizing the fixation of the drying packet 6. In this embodiment, a V-shaped structure is formed at the top of the light homogenizing cover body 51, and the limiting groove 53 is formed by the V-shaped structure at the top of the light homogenizing cover body 51 and the fitting portion 52 to prevent the drying packet 6 from moving relative to the light homogenizing housing 5. Since the installation position of the drying packet 6 is determined by the shape of the integrally formed light homogenizing housing 5, the installation efficiency of the drying packet 6 is improved, and the fitting portion 52 is fitted to the second area outside the light source area, preventing the position of the drying packet 6 from shifting to the light source area and preventing the drying packet 6 from affecting the illumination effect of the logo.

[0051] See Figures 2 to 4As shown, in some alternative embodiments, the lamp cover 3 may include an outer cover body 32 and an inner cover body 31; the inner cover body 31 may be provided with shaping holes 311; the outer cover body 32 may be located on the side of the inner cover body 31 away from the circuit board 2, the outer cover body 32 may be made of a light-transmitting material, and the outer cover body 32 may be provided with an aluminized layer 321 corresponding to the shaping holes 311. That is to say, by providing the shaping holes 311 in the light-shielding inner cover body 31 to restrict the light propagation of the light source 21, the lighting effect in the design is achieved. By providing the aluminized layer 321 corresponding to the shaping holes 311 on the light-transmitting outer cover body 32 to let the light out. A logo can be found outside, and the logo emits the effect of an electroplated logo, and a high-brightness black effect is generated around the logo. The texture of the logo is improved. In this embodiment, the outer cover body 32 is made of transparent PC material, and the inner cover body is made of black PMMA (polymethyl methacrylate). In this embodiment, the side of the outer cover body 32 close to the circuit board 2 is integrally plated with an aluminum layer. In this embodiment, the outer cover body 32 and the inner cover body 31 are combined into the lamp cover 3 by two-color injection molding, which can improve the connection tightness between the two cover bodies. To achieve a preset light-transmitting effect and prevent light from leaking out through the gap between the two cover bodies. In this embodiment, the shape of the shaping holes 311 is the same as the shape of the vehicle logo.

[0052] See Figure 3 , Figure 5 and Figure 6 As shown, in some alternative embodiments, the lamp cover 3 may be provided with a first welding rib 33, and the first welding rib 33 may surround the accommodation cavity 4; the mounting housing 1 may be provided with a second welding rib 113 matching the first welding rib 33; the first welding rib 33 and the second welding rib 113 are connected by friction welding to achieve a sealed connection between the mounting housing 1 and the lamp cover 3. That is to say, the lamp cover 3 and the mounting housing 1 are connected by friction welding to form a sealed accommodation cavity 4. Among them, since the lamp cover 3 is provided with the first welding rib 33 and the mounting housing 1 is provided with the second welding rib 113, friction welding can be achieved through the side contact of the two welding ribs, and water vapor can be isolated by the protruding structures of the two welding ribs. At the same time, since the first welding rib 33 surrounds the accommodation cavity 4, the four sides of the accommodation cavity 4 can be sealed after the first welding rib 33 and the second welding rib 113 are connected.

[0053] See Figures 1 to 4As shown, in some alternative embodiments, a positioning boss 114 may be provided on a side of the mounting housing 1 away from the lamp shade 3. The positioning boss 114 is used to be fixed to a vehicle. The positioning surface of the positioning boss 114 is biased away from the lamp shade 3 compared to the heat dissipation device 12. That is to say, the mounting housing 1 is fixed to the vehicle through the positioning boss 114, and by setting the positioning surface of the positioning boss 114 to be farther away from the lamp shade 3 than the heat dissipation device 12, that is, the positioning surface of the positioning boss 114 protrudes farther outwards than the heat dissipation device 12, so as to leave a gap between the heat dissipation device 12 and the vehicle when the mounting housing 1 is mounted on the vehicle, avoiding interference when the logo is mounted on the vehicle. This facilitates the installation of the vehicle logo.

[0054] See Figure 4 As shown, in some alternative embodiments, a fiber board 7 may also be provided between the circuit board 2 and the heat dissipation device 12. Through the fiber board 7, the heat on the circuit board 2 can be evenly guided to the heat dissipation device. In this embodiment, the circuit board 2 is a PCB (Printed Circuit Board) board, and BOSS posts 124 are provided on the heat dissipation device 12. Screws 8 are provided on the circuit board 2. The screws 8 sequentially pass through the circuit board 2, the fiber board 7 and are connected to the BOSS posts 124 of the heat dissipation device 12 to ensure tight connection among the three and improve the heat transfer efficiency among the three. See Figure 6 As shown, screws 8 are also provided between the light homogenizing housing 5 and the mounting housing 1. By pressing the end face of the light homogenizing housing 5 with the screws 8, the connection between the light homogenizing housing 5 and the mounting housing 1 is ensured to be reliable.

[0055] The principle of an automotive logo provided by an embodiment of the present invention is as follows:

[0056] By attaching the circuit board 2 to the heat dissipation device 12 and arranging the heat dissipation device 12 on the outside of the mounting housing 1, when the logo is mounted on the vehicle, the heat dissipation device 12 is in contact with the outside air. Compared with the heat dissipation mechanism arranged inside the accommodation cavity 4, the heat dissipation device 12 not only cools the circuit board 2 by contacting the circuit board 2, but also, because it is arranged on the outside of the mounting housing 1, can guide the heat to the outside air, avoiding the increase in temperature inside the accommodation cavity 4. The heat in the accommodation cavity 4 can be guided to the air through the heat dissipation device 12, reducing the overall temperature of the logo. This is to prevent discomfort caused by the high temperature of the logo when a person touches the logo. At the same time, because the heat dissipation device 12 is arranged on the outside of the mounting housing 1, it does not occupy the space inside the accommodation cavity 4, reducing the layout difficulty inside the accommodation cavity 4.
