The imaging component 120 is disposed inside the housing 110 in an embedding manner, a clamping manner, or the like, and the imaging component 120 is used for receiving incident light of the light inlet 111, that is, the incident light can enter the housing 110 through the light inlet 111 and is projected to the imaging component 120, and the incident light is converted into an image through the imaging component 120 to perform shooting operation.

The optical glass 130 is disposed on a side of the housing 110 away from the imaging component 120 in an embedding manner, a clamping manner, and the like, and the optical glass 130 covers the light inlet 111, so that the optical glass 130 can allow incident light to pass through, and impurities such as external dust can be prevented from entering the housing 110, thereby protecting the imaging component 120.

The heating element 140 is disposed on the housing 110 by embedding, clamping, etc., and the heating element 140 is located between the imaging assembly 120 and the optical glass 130. As in the present embodiment, the heating element 140 is disposed near the optical glass 130, and the heating element 140 is at least partially in contact with the optical glass 130, the heating element 140 being for heating the optical glass 130. Specifically, when the lens module 100 is in a wet and cold working environment, the heating element 140 can heat the optical glass 130 to prevent water vapor from adhering to the surface of the optical glass 130 to form micro dew, i.e. to avoid the adverse phenomena of imaging and fogging of the lens module 100 in the wet and cold environment, thereby improving the imaging quality of the lens module 100 in different environments.

In this embodiment, the heating element 140 is a resistor rod or a resistor wire, when the heating element 140 is energized, the heating element 140 can generate heat, and a heat-conducting glue is disposed at a contact position between the heating element 140 and the optical glass 130, so that the heat generated by the heating element 140 can be quickly transferred to the optical glass 130 through the heat-conducting glue, and the response timeliness of the heating element 140 to the defogging operation on the surface of the optical glass 130 is improved.

In order to perform the heating operation on the optical glass 130, in one embodiment, as shown in fig. 1-3, the lens module 100 further includes a temperature detecting component 141. The temperature detecting component 141 is connected with the heating element 140, and the temperature detecting component 141 is used for controlling the heating of the heating element 140, so that the heating element 140 can heat the optical glass 130 to prevent water vapor from adhering to the surface of the optical glass 130 to form tiny dew, namely, the adverse phenomenon of imaging and fogging of the lens module 100 in a wet and cold environment is avoided, and further, the imaging quality of the lens module 100 in different environments is improved.

The heating element 140 is connected with the probe 142 and the temperature sensor 143, for example, the heating element 140 can be connected with the probe 142 by a wire, bluetooth and the like, so that the probe 142 can feed back a temperature signal to the heating element 140 and control the energizing operation of the heating element 140; similarly, the heating element 140 may be connected to the temperature sensor 143 by a wire, bluetooth, etc. so that the temperature sensor 143 may feed back a temperature signal to the heating element 140 and control the heating operation of the heating element 140. The heating element 140 is disposed on the housing 110, and the heating element 140 contacts with the optical glass 130, so that during the operation of the heating element 140, heat generated by the heating element 140 can be directly transferred to the optical glass 130, so as to remove mist generated on the surface of the optical glass 130 or destroy the condition of generating mist on the surface of the optical glass 130, and improve the heat transfer efficiency of the heating element 140. The probe 142 extends at least partially outside the optical glass 130, the probe 142 is used for detecting the temperature of the external environment, and the temperature sensor 143 is used for detecting the temperature of the optical glass 130. Specifically, if the probe 142 detects that the external environment temperature is less than or equal to a first preset temperature, that is, when the lens module 100 is in a wet and cold working environment, the probe 142 feeds back a temperature signal to the control element, the control element controls the power-on heating operation of the heating element 140, and when the temperature sensor 143 detects that the temperature of the optical glass 130 is greater than or equal to a second preset temperature, that is, the condition that the surface temperature of the optical glass 130 can remove mist generated on the surface of the optical glass 130 or damage the surface of the optical glass 130 to generate mist is indicated, at this time, the temperature sensor 143 feeds back the temperature signal to the control element, and the control element controls the power-off operation of the heating element 140 or reduces the power of the heating element 140; and when the temperature sensor 143 detects that the temperature of the optical glass 130 is less than the second preset temperature again, the control element controls the power-on operation of the heating element 140 or increases the power of the heating element 140, so as to avoid the adverse phenomena of imaging and fogging of the lens module 100 in a wet and cold environment. By repeating the control actions of the heating element 140, fog generated on the surface of the optical glass 130 can be removed or the condition of fog generated on the surface of the optical glass 130 can be destroyed during the working of the lens module 100, so that the imaging quality of the lens module 100 under different environments can be improved.

It should be noted that, during the heating process of the optical glass 130 by the heating element 140, the temperature sensor 143 may monitor the temperature change of the optical glass 130 in real time, that is, the temperature sensor 143 may monitor the temperature change of the optical glass 130 during the whole heating process of the optical glass 130.

To achieve the mounting and fixing of the heating element 140, in an embodiment, as shown in fig. 1-3, the lens module 100 further includes a first bracket 144.

As in the present embodiment, the mounting plate 1442 and the clamping post 1441 are integrally formed by injection molding, extrusion, etc., so as to simplify the manufacturing process of the first bracket 144 and save the manufacturing cost of the first bracket 144. The heating element 140 and the temperature sensor 143 are embedded on the mounting plate 1442, and the mounting plate 1442 is fixed on the housing 110 through the clamping post 1441, so that the mounting and fixing of the heating element 140 and the temperature sensor 143 on the housing 110 can be indirectly realized through the mounting plate 1442. And the heating element 140 contacts with the optical glass 130, so that heat generated by the heating element 140 can be rapidly transmitted to the optical glass 130 to heat and defog the optical glass 130.
