[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides a backlight source for an electronic rearview mirror, comprising a mounting frame 1, a contact rod 2 8 is fixedly connected to the inner cavity of the mounting frame 1, a heat sink 9 is fixedly connected to the rear side of the contact rod 2 8, a heat sink 10 is fixedly connected to the rear side of the heat sink 9, a clamping plate 6 is fixedly connected to the front side of the mounting frame 1, a contact rod 1 7 is fixedly connected to the rear side of the clamping plate 6, and a backlight source panel 11 is placed in the inner cavity of the mounting frame 1;

[0023] By setting the contact rod 28, when the backlight source panel 11 is placed in the inner cavity of the mounting frame 1, the heat generated during the use of the backlight source panel 11 can be transferred to the inner cavity of the heat sink 9 through the contact rod 28, and then the heat is quickly absorbed by the coolant in the inner cavity of the heat sink 9, and then the heat absorbed by the coolant in the inner cavity of the heat sink 9 is transferred to the air through the heat sink 10, thereby avoiding the situation where the heat dissipation of the backlight source panel 11 is poor when used in an environment with a high temperature.

[0024] The left and right sides of the installation frame 1 are both movably sleeved with installation plates 2, and the installation plates 2 are fitted with the backlight source plate 11;

[0025] By setting the mounting plate 2, the mounting plate 2 can be disassembled, and the backlight source panel 11 can be pulled out from the left and right sides of the mounting frame 1, thereby improving the stability of the backlight source panel 11 when it is located in the inner cavity of the mounting frame 1, thereby avoiding the backlight source panel 11 from shifting due to shaking while the vehicle is driving.

[0026] Wherein, the rear side of the contact rod 2 8 is located in the inner cavity of the heat dissipation box 9;

[0027] The rear side of the contact rod 2 8 is located in the inner cavity of the heat sink 9 , so that the contact rod 2 8 can transfer heat to the inner cavity of the heat sink 9 and transfer the heat to the inside of the coolant, so that the backlight source panel 11 can be cooled quickly.

[0028] The heat sink 9 is a rectangular hollow body, and the inner cavity of the heat sink 9 is filled with coolant;

[0029] Since the heat dissipation box 9 is a rectangular hollow body, the inner cavity of the heat dissipation box 9 can be filled with cooling liquid, and the heat of the backlight source panel 11 can be quickly absorbed by the cooling liquid.

[0030] The front side of the heat sink 10 is located in the inner cavity of the heat sink box 9, and the rear side of the heat sink 10 is located outside the heat sink box 9;

[0031] The front side of the heat sink 10 is located in the inner cavity of the heat sink 9, so that the heat sink 10 is in contact with the coolant in the inner cavity of the heat sink 9, so that the heat absorbed by the coolant can be transferred to the heat sink 10, and then transferred to the air through the heat sink 10, so that the heat sink 10 can dissipate heat and cool it.

[0032] Among them, the rear side of the contact rod 7 is a rubber head, and the rubber head contacts the front side of the backlight source plate 11;

[0033] The rear side of the contact rod 7 is provided with a rubber head, thereby preventing the contact rod 7 from contacting the backlight source panel 11 and causing damage to the front side of the backlight source panel 11 .

[0034] The top of the mounting plate 2 is fixedly connected with a locking plate 3, and one side of the locking plate 3 close to the center of the mounting frame 1 is fixedly connected with an elastic plate 4;

[0035] The backlight source panel 11 is blocked by the mounting plate 2, so that the backlight source panel 11 in the inner cavity of the mounting frame 1 deviates from the inner cavity of the mounting frame 1, and then the elastic plate 4 is inserted into the inner cavity of the limiting groove 5, so that the elastic plate 4 can be snapped into the inner cavity of the limiting groove 5, thereby fixing the mounting plate 2.

[0036] Wherein, the left and right sides of the installation frame 1 are fixedly provided with limit grooves 5, and the inner cavity of the limit grooves 5 is fixedly installed with elastic sheets;

[0037] Through the limiting grooves 5 on the left and right sides of the mounting frame 1, the elastic sheets in the inner cavity of the limiting grooves 5 can clamp the elastic plate 4, thereby limiting the elastic plate 4, fixing the mounting plate 2, and thus limiting and fixing the backlight source plate 11.

[0038] The working principle and use process of the utility model are as follows: the mounting plate 2 is taken out from the side of the mounting frame 1, and then the backlight source panel 11 is placed into the inner cavity of the mounting frame 1, so that the contact rod 2 8 and the contact rod 1 7 are in contact with and clamp the backlight source panel 11, and then the mounting plate 2 is inserted into the inner cavity of the limiting groove 5 through the locking plate 3, so that the backlight source panel 11 is limited and fixed by the mounting plate 2;

[0039] Then, through the contact between the contact rod 2 8 and the backlight panel 11, the heat generated by the backlight panel 11 during use can be transferred to the inner cavity of the heat sink 9 through the contact rod 2 8, and then the heat absorbed by the inner cavity of the heat sink 9 is transferred to the air through the heat sink 10 for dissipation.
