[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. The described embodiments are part of the embodiments of the present application, but not all of the embodiments of the present application.

[0038] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0039] Example 1:

[0040] Please refer to the accompanying Figure 1 , Figure 3 The vehicle-mounted lens capable of actively melting ice and snow of the present application comprises a lens assembly 1, a base shell 2 and a heating assembly 3.

[0041] Among them, please see Figure 1 , Figure 1 The structural relationship among the lens assembly 1, the base shell 2 and the heating assembly 3 in the embodiments of the present application is shown. Specifically, the base shell 2 is provided with a mounting cavity 21 for mounting the lens assembly 1; the heating assembly 3 is installed between the lens assembly 1 and the base shell 2; wherein the upper end surface of the connection between the base shell 2 and the lens assembly 1 is also provided with an accommodating cavity 22, and the heating assembly 3 is installed in the accommodating cavity 22.

[0042] In the embodiment, the lens assembly 1 is installed in the mounting cavity 21 of the base shell 2 to improve the connection stability between the base shell 2 and the lens assembly 1. In order to ensure the normal work of the lens assembly 1 in a cold and low-temperature environment, the heating assembly 3 is installed in the accommodating cavity 22 opened on the upper end surface of the connection position between the base shell 2 and the lens assembly 1, and the heat of the heating assembly 3 is radiated and / or conducted to the lens assembly 1 by heat radiation and / or heat conduction, so as to improve the temperature of the lens assembly 1, and further ensure the normal work of the lens assembly 1 in a cold and low-temperature environment such as ice and snow. The specific installation process of the vehicle-mounted lens capable of actively melting ice and snow is as follows: first, the heating assembly 3 is installed in the accommodating cavity 22 of the base shell 2, and then the lens assembly 1 is installed in the mounting cavity 21 of the base shell 2, so that the lens assembly 1 is fixed in the mounting cavity 21 and connected to the upper end surface of the base shell 2. In this way, the heating assembly can radiate and / or conduct heat to the lens assembly 1, so that the lens assembly 1 generates heat to melt ice and snow, and further ensure the reliability of the heating assembly in a cold and low-temperature environment such as ice and snow. Preferably, the lens assembly 1 is integrally formed.

[0043] It can be understood that, since the lens assembly 1 is integrally formed, when the heating assembly 3 is installed between the lens assembly 1 and the base shell 2, it will not interfere with the optical imaging of the lens assembly 1, and the installation process of the heating assembly 3 does not cross the lens optical process, so as not to affect the optical yield, thereby avoiding the problem that the installation of the heating assembly 3 in the lens assembly 1 will interfere with the lens optical production, and further cause low optical process yield and high scrap rate. At the same time, the production and assembly process is simple, and it is convenient for mass production.

[0044] Further, the heating assembly 3 abuts against the lens assembly 1 to make the heat radiation and / or conduction effect stronger, and further make the heating efficiency more superior. It should be noted that the contact surface of the lens assembly 1 and the accommodating cavity 22 is made of metal material, and the heat conduction effect is better. Preferably, heat-conducting silicone grease can be added to the contact surface of the lens assembly 1 and the accommodating cavity 22 to enhance the heat conduction effect, and further melt the ice and snow quickly.

[0045] The above-mentioned vehicle-mounted lens capable of actively melting ice and snow, the upper end surface of the connection position between the base shell 2 and the lens assembly 1 is provided with the accommodating cavity 22, and the heating assembly 3 is installed in the accommodating cavity 22, so that when the heating assembly 3 generates heat, the heat can be conducted to the lens assembly 1 by heat radiation and / or heat conduction, further realizing the heating of the lens assembly 1 to melt the ice and snow, so that the lens assembly 1 can work normally in an ice and snow environment, and meanwhile, the assembly of the optical lens 13 is not disturbed. The installation of the heating assembly 3 in the lens assembly 1 will not interfere with the lens optical production. Moreover, the production and assembly process is simple, and it is convenient for mass production.

[0046] In some preferred embodiments, the mounting cavity 21 and the accommodating cavity 22 are in communication. The contact area between the heat-generating component 3 and the lens assembly 1 is increased, so that the heat-generating component 3 has a better heating effect on the lens assembly 1, thereby having a more superior ice and snow melting effect, and meanwhile facilitating the production and assembly, thereby improving the production and assembly efficiency of the vehicle-mounted lens capable of actively melting ice and snow.

[0047] In some preferred embodiments, please refer to Figure 2 , Figure 2 The structural relationship between the heat-generating component 31 and the wire 32 in the embodiment of the utility model is shown. Specifically, the heat-generating component 3 comprises the heat-generating component 31 and the wire 32 for connecting the external circuit, the base shell 2 is further provided with a through hole 23 in communication with the accommodating cavity 22, the heat-generating component 31 is installed in the accommodating cavity 22 and abuts against the lens assembly 1, the wire 32 is arranged in the through hole 23, and the heat-generating component 31 is electrically connected with the external circuit through the wire 32. The heat-generating component 31 abuts against the lens assembly 1, so that the heat conduction effect is better, the wire 32 is arranged in the through hole 23 and connected with the heat-generating component 31, so as to provide power output for the heat-generating component 31 and ensure the reliability of the continuous heating of the heat-generating component 31. The wire 32 is arranged in the through hole 23 of the base shell 2, thereby avoiding the problem that when the wire 32 is arranged outside the base shell 2, the volume of the entire vehicle-mounted lens is increased and the external power supply wiring reliability is low. It can be understood that the wire 32 can be an FPC electric connection flat cable, so that when the vehicle-mounted lens is installed, the FPC electric connection flat cable is only inserted into the FPC connector, thereby ensuring the normal use of the vehicle-mounted lens and reducing the welding process.

[0048] In some preferred embodiments, please continue to refer to Figure 2 , Figure 2 The structural relationship between the heat-generating component 31 and the wire 32 in the embodiment of the utility model is shown. Specifically, the heat-generating component 3 comprises the heat-generating component 31 and the wire 32 for connecting the external circuit, the base shell 2 is further provided with a through hole 23 in communication with the accommodating cavity 22, the heat-generating component 31 is installed in the accommodating cavity 22 and abuts against the lens assembly 1, the wire 32 is arranged in the through hole 23, and the heat-generating component 31 is electrically connected with the external circuit through the wire 32. The heat-generating component 31 abuts against the lens assembly 1, so that the heat conduction effect is better, the wire 32 is arranged in the through hole 23 and connected with the heat-generating component 31, so as to provide power output for the heat-generating component 31 and ensure the reliability of the continuous heating of the heat-generating component 31. The wire 32 is arranged in the through hole 23 of the base shell 2, thereby avoiding the problem that when the wire 32 is arranged outside the base shell 2, the volume of the entire vehicle-mounted lens is increased and the external power supply wiring reliability is low. It can be understood that the wire 32 can be an FPC electric connection flat cable, so that when the vehicle-mounted lens is installed, the FPC electric connection flat cable is only inserted into the FPC connector, thereby ensuring the normal use of the vehicle-mounted lens and reducing the welding process.

[0049] In some preferred embodiments, the heating assembly 3 further comprises a temperature sensing member 34, which is arranged in the through hole 23 and is used for sensing the temperature of the heating member 31. The temperature sensing member 34 is arranged in the through hole 23 to obtain the actual temperature of the heating member 31, and when the actual temperature of the heating member 31 reaches a preset temperature, the temperature sensing member 34 feeds back the actual temperature of the heating member 31 to an external controller, and the controller controls an external circuit to cut off power output, so that the heating member 31 stops heating. It can be understood that since the lens assembly 1 is continuously affected by external ice and snow, the temperature of the lens assembly 1 will continuously conduct to the heating member 31, so that the temperature of the heating member 31 close to the lens assembly 1 reaches equilibrium with the temperature in the through hole 23 affected by the heat insulation member 33. In this way, the temperature sensing member 34 can accurately sense the actual temperature of the heating member 31, and further sense the actual heating temperature of the lens assembly 1. In this way, the heating temperature can be set according to the external ice and snow conditions, so that the ice and snow can be quickly melted.

[0050] In some more preferred embodiments, please refer to Figure 3 , Figure 3 The structure relationship between the lead portion 35 and the heat insulation member 33 in the embodiment of the utility model is shown. Specifically, the heat insulation member 33 is provided with a communication hole 331, the heating member 31 extends the lead portion 35 arranged in the communication hole 331, and the lead wire 32 is electrically connected to the heating member 31 through the lead portion 35. The communication hole 331 is communicated with the through hole 23, and the lead wire 32 is connected to the heating member 31 through the lead portion 35, which avoids the problem that the heating member 31 directly contacts the lead wire 32 and causes damage to the lead wire 32 when the temperature of the heating member 31 is too high, and further avoids the problem that the lead portion 35 and the lens assembly 1 or the base shell 2 are scratched, which causes poor electrical connection between the lead portion 35 and the lead wire 32, and further prolongs the service life of the heating assembly 3.

[0051] Embodiment 2:

[0052] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the vehicle-mounted lens capable of actively melting ice and snow of the utility model, please refer to the accompanying Figure 4 .

[0053] In this embodiment, please refer to Figure 4 , Figure 4 The structure relationship between the accommodating groove 11, the accommodating cavity 22 and the heating member 31 in the embodiment of the utility model is shown. Specifically, the lens assembly 1 is further provided with the accommodating groove 11 communicated with the accommodating cavity 22 on the side close to the accommodating cavity 22, and the heating member 31 abuts against the bottom wall of the accommodating groove 11.

[0054] In this embodiment, the heating element 31 is installed in the receiving groove 11 and abuts the bottom wall of the receiving groove 11, increasing the contact area between the heating element 31 and the lens assembly 1, so that the heating element 31 has a better heating effect on the lens assembly 1, further enhancing the efficiency of the lens assembly 1 in melting ice and snow, thereby quickly melting ice and snow and ensuring the continued normal operation of the lens assembly 1. At the same time, the receiving groove 11 acts as a limiter for the heating element 31, making the connection between the heating element 31 and the lens assembly 1 more stable, ensuring the reliability of the vehicle-mounted lens that can actively melt ice and snow.

[0055] In some preferred embodiments, the heating element 31 is an annular heating element 31. The heating element 31 is distributed along the circumference of the lens assembly 1 close to the accommodating cavity 22 to uniformly heat the lens assembly 1 and ensure the balance of the heating temperature when the lens assembly 1 is heated, so that the ice and snow outside the lens assembly 1 melt evenly. It can be understood that the heating element 31 is not limited to an annular heating element 31, and can also be a block-shaped heating element 31. A plurality of heating elements 31 are evenly spaced along the circumferential direction of the lens to uniformly heat the lens assembly 1 and thus evenly melt the ice and snow. Preferably, the heat insulating element 33, the accommodating cavity 22 and the accommodating groove 11 are all set to an annular shape to improve the connection stability between the heating element 3 and the lens assembly 1 and the base shell 2 respectively, further ensure the reliability of the heating element 3, so that the heating effect of the heating element 3 on the lens assembly 1 is more superior, and thus the lens assembly 1 has a better melting effect on ice and snow.

[0056] Example 3:

[0057] The difference between this embodiment and embodiment 2 is that this embodiment further optimizes the structure of the vehicle-mounted lens capable of actively melting ice and snow of the utility model. Figure 5 .

[0058] Among them, see Figure 5 , Figure 5 The diagram illustrates the structural relationship between the lens barrel 12 and the lens 13 in an embodiment of the present invention. Specifically, the lens assembly 1 includes the lens barrel 12 and the lens 13. The lens barrel 12 is mounted in the mounting cavity 21, and the lens 13 is connected to the side of the lens barrel 12 away from the mounting cavity 21. The heating component 3 abuts the side of the lens barrel 12 away from the lens 13.

[0059] In this embodiment, the heating component 3 is in contact with the side of the lens barrel 12 facing away from the lens 13. When the heating component 3 generates heat, it transfers the heat to the lens barrel 12, which then transfers the heat to the lens 13 through the lens barrel 12. Since the lens barrel 12 is made of metal, it can effectively transfer the heat to the lens 13, thereby heating the lens 13 and melting the ice and snow, thereby ensuring that the lens assembly 1 can operate normally in an ice and snow environment.

[0060] It can be understood that when the vehicle is running in the ice and snow environment, the lens 13 is affected by the ice and snow, which can easily cause the lens assembly 1 to lose function and cannot work normally. Since the heating assembly 3 abuts against the side of the lens barrel 12 away from the lens 13, the lens barrel 12 can well conduct the heat generated by the heating assembly 3 to the lens 13, so that the lens 13 generates heat and then melts the ice and snow, thereby preventing the lens 13 from icing, so that the lens assembly 1 can work normally in the ice and snow environment. At the same time, the problem that the heating efficiency is low and the ice and snow cannot be quickly melted when the heating assembly 3 is far away from the lens 13 is avoided.

[0061] In some preferred embodiments, the side wall of the mounting cavity 21 is provided with a calibration surface 211, and the lens barrel 12 is provided with a calibration section 121 which abuts against the calibration surface 211. The calibration section 121 of the lens barrel 12 is put into alignment with the calibration surface 211 of the mounting cavity 21, so as to ensure the coaxiality between the lens assembly 1 and the base shell 2, thereby ensuring the reliability of the vehicle-mounted lens which can actively melt ice and snow. At the same time, the connection area between the lens assembly 1 and the base shell 2 is increased, the connection stability is improved, and the overall compactness is further improved.

[0062] In some more preferred embodiments, the side wall of the mounting cavity 21 is further provided with a threaded surface 212, and the lens barrel 12 is further provided with a threaded section 122 which is screwed with the threaded surface 212. The calibration surface 211 and the threaded surface 212 are sequentially distributed along the axial direction of the mounting cavity 21, and the calibration section 121 and the threaded section 122 are sequentially distributed along the axial direction of the lens barrel 12. The calibration surface 211 and the calibration section 121 abut against each other, so as to ensure the coaxiality between the lens assembly 1 and the base shell 2. The threaded section 122 is screwed with the threaded surface 212, so as to further enhance the connection stability between the lens assembly 1 and the base shell 2. Preferably, the calibration section 121 has a first calibration section 121 and a second calibration section 121, the calibration surface 211 has a first calibration surface 211 and a second calibration surface 211, the first calibration section 121 abuts against the first calibration surface 211, the second calibration section 121 abuts against the second calibration surface 211, the threaded surface 212 is arranged between the first calibration surface 211 and the second calibration surface 211, and the threaded section 122 is arranged between the first calibration section 121 and the second calibration section 121. The coaxiality between the lens assembly 1 and the base shell 2 is ensured on the premise that the lens assembly 1 and the base shell 2 are stably connected, thereby further ensuring the reliability of the vehicle-mounted lens which can actively melt ice and snow.

[0063] The vehicle-mounted lens capable of actively melting ice and snow of the utility model, the upper end face of the connecting place of base shell 2 and lens assembly 1 is provided with accommodating cavity 22, heating assembly 3 is installed in accommodating cavity 22, so that heating assembly 3 can conduct heat to lens assembly 1 through the mode of heat radiation and / or heat conduction when heating, further realize that lens assembly 1 heats, melts ice and snow, so that lens assembly 1 can work normally under the ice and snow environment, and meanwhile do not disturb the assembly of optical lens 13.The problem that the heating assembly 3 is installed in the inside of lens assembly 1 and can cause the interference of lens optical production is avoided.The production and assembly process is simple, and it is beneficial to mass production.
