For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0044] Please refer to Figure 1 、 Figure 2 and Figure 3 The camera provided by the present invention includes a fixing component 1, a camera module 2, a temperature sensor 3, a heating element 4 and a circuit board 5.

[0045] The camera module 2 , the temperature sensor 3 and the circuit board 5 are all arranged on the fixing component 1 .

[0046] The camera module 2 includes at least one lens 201 arranged in sequence from the object side to the image side, and the heating element 4 is arranged on the side wall of the lens 201 closest to the object side.

[0047] The circuit board 5 includes a heating control module 501 , which is electrically connected to the temperature sensor 3 and the heating element 4 .

[0048] The heating control module 501 is used to switch the on / off and heating modes of the heating element 4 according to the temperature sensor 3 .

[0049] Based on the above structure, the temperature sensor 3 can detect the camera temperature of the environment in which the camera is located in real time and send the detected camera temperature to the heating control module 501. The heating control module 501 switches the on / off and heating mode of the heating element 4 according to the camera temperature. That is, when the camera temperature is a safe temperature without frost or fog, the heating element 4 is controlled to be off. When the camera temperature is a dangerous temperature where frost or fog will form, the heating element 4 is controlled to be on. The heating element 4 is also controlled to heat at a temperature suitable for the dangerous temperature for a period of time according to the temperature to defrost and defog.

[0050] By disposing a heater 4 on the side wall of the lens 201 closest to the object in the camera module 2, the heating control module 501 switches the on / off and heating mode of the heater 4 based on the temperature sensor 3, thereby heating the outermost lens 201 in the camera module 2 (i.e., the lens 201 that is subject to frost, ice, and fog), thereby automatically performing defrosting, melting ice, and defogging. Furthermore, the heating control module 501 switches the on / off and heating mode of the heater 4 based on the temperature sensor 3, thereby facilitating the use of different heating temperatures and durations under different ambient temperatures, thereby avoiding constant high-temperature heating. This improves the efficiency of defrosting, melting ice, and defogging, protects the camera, and reduces damage to the camera caused by heating.

[0051] In order to quickly defrost while reducing damage to the camera and energy consumption, multiple heating scenarios are introduced into the camera. For example, the heating element 4 has multiple heating modes, each of which includes a heating duration and a heating temperature.

[0052] For example, when the camera temperature is detected to be -40°C, the heating element 4 is controlled to heat at the first temperature. After the heating time reaches 3m30s, if the temperature sensor 3 detects that the lens temperature has risen to -20°C, the heating element 4 is controlled to heat at the second temperature. After the heating time reaches 2m, if the temperature sensor 3 detects that the lens temperature has risen to -4°C and the defrosting effect has been achieved, the heating element 4 can continue to heat the lens 201 at the third temperature to maintain the defrosted state. The first temperature is greater than the second temperature, and the second temperature is greater than the third temperature.

[0053] It should be noted that the heating temperature is no greater than the heat-resistant temperature of the lens 201 of the camera module 2 .

[0054] Through the above method, different heating temperatures and heating times are used at different camera temperatures. The lower the camera temperature, the higher the heating temperature, enabling faster defrosting and defogging. Furthermore, the higher the camera temperature, the longer the heating time, ensuring sufficient heating of the camera for ice melting, defrosting, and defogging, improving the defrosting and defogging effect. Furthermore, using different heating temperatures and heating times at different camera temperatures prevents damage to the camera due to excessive heating temperature or power, thereby protecting the camera.

[0055] Furthermore, the camera can be equipped with an ambient temperature sensor electrically connected to the heating control module 501. When the ambient temperature detected by the ambient temperature sensor approaches a safe temperature without frost or fogging, the heating control module 501 turns off the heating element 4. When the ambient temperature detected by the ambient temperature sensor reaches the threshold for initiating heating and defrosting, the heating control module 501 automatically activates the heating and defrosting function. The heating element 4 can be heated periodically. When the heating time reaches a set value and the camera temperature rises to a set value, the heating is stopped or the temperature is lowered to prevent overheating from damaging the camera's lifespan. Furthermore, multiple temperature values can be set, along with corresponding heating times and temperatures. Heating automatically stops when the corresponding time and temperature are reached.

[0056] The setting of the heating element 4 can be flexibly selected. For example, it can be multiple thermal resistors or heating plates connected in series or in parallel along the circumference of the lens 201, or it can be an electric heating film or a thermocouple. The above method is only an example and is not limited in this embodiment.

[0057] In order to make the various areas of the lens 201 closest to the object side be heated evenly, refer to Figure 2 The heating element 4 may include a heating wire 401 and a heating cable 402 . The heating wire 401 is connected to the heating control module 501 via the heating cable 402 . The heating wire 401 is disposed on the lens 201 closest to the object side and is disposed circumferentially along the lens 201 .

[0058] The camera module 2 further includes a lens barrel 202, and a plurality of lenses 201 of the camera module 2 are sequentially arranged in the lens barrel 202. The heating wire 401 can be fixed to the side wall of the lens 201 by bonding, welding, etc., or can be embedded in the gap between the lens 201 and the lens barrel 202.

[0059] Through the above-mentioned structure of the heating element 4, the heating wire 401 is in contact with each circumferential area of the lens 201, so that in the heating mode, each area of the lens 201 is heated evenly, thereby avoiding the situation where some areas have low heating temperatures and slow defrosting and defogging speeds, while some areas have high heating temperatures and fast defrosting and defogging speeds. At the same time, it can avoid the situation where some areas are damaged due to excessively high temperatures.

[0060] To ensure that heating is stopped promptly upon completion of defrosting and defogging, thereby protecting the camera and reducing energy consumption, a heating result recognition mechanism is incorporated into the camera. The configuration of this heating result recognition mechanism can be flexibly configured. For example, it can be a mechanism that identifies the clarity of images captured by the camera after heating. Alternatively, it can be a timer that starts counting when heating begins and, when the count reaches a predetermined duration threshold, sends a stop command or a temperature reduction command to the heating control module 501, thereby stopping heating or lowering the heating temperature.

[0061] The time threshold may be a value determined based on the results of a pre-determined heating, defrosting, and defogging calibration test, indicating the heating time required for the image captured by the camera to achieve the target clarity. Furthermore, the above method is merely an example, and the implementation of the heating result recognition mechanism is not limited thereto.

[0062] In order to reduce hardware costs, this embodiment can also use the inherent control equipment of the environment where the camera is located to realize the heating result recognition mechanism. Figure 4 The circuit board 5 further includes an image capturing module 502 and a transmission module 503 . The transmission module 503 is electrically connected to the image capturing module 502 and the back-end controller 6 , respectively.

[0063] The transmission module 503 is used to transmit the image capture information of the image capture module 502 to the back-end controller 6 , and transmit the image processing result of the image capture information by the back-end controller 6 to the heating control module 501 .

[0064] The heating control module 501 is used to switch the on / off and heating mode of the heating element 4 according to the image processing result of the back-end controller 6 and the temperature sensor 3.

[0065] Among them, the image capture module 502 may include a light sensor and an encoder. The light sensor is used to sense the light energy passing through the camera module 2 and convert the light energy into an electrical signal. The encoder encodes the electrical signal to obtain image capture information (actually the image data captured by the camera). The back-end controller 6 is the inherent hardware of the device in the application scenario of the camera. For example, when the camera is an exterior rearview camera of a vehicle, the back-end controller 6 can be the vehicle's in-vehicle entertainment terminal, SOC or MCU, etc. When the back-end controller 6 is applied to urban monitoring, the back-end controller 6 can be a monitoring processor, etc. In this embodiment, the implementation method of the back-end controller 6 is not limited.

[0066] Based on the above structure, while the heating element 4 is heating, defrosting, and defogging the camera, the image capture module 502 can capture image information (i.e., image data) at a preset capture time interval and transmit the image information to the backend controller 6 via the transmission module 503. The backend controller 6 processes the image information to obtain a resolution, which it then transmits as an image processing result to the heating control module 501. The heating control module 501 switches the heating element 4 on and off and the heating mode based on the camera temperature currently captured by the temperature sensor 3 and the image processing result.

[0067] For example, when the camera temperature detected by temperature sensor 3 is -40°C, indicating a low-temperature environment, heating control module 501 controls heater 4 to heat lens 201 at a first heating temperature. Simultaneously, image capture module 502 periodically captures image information and transmits it via transmission module 503 to backend controller 6. Backend controller 6 processes the image information to determine clarity, which is then transmitted to heating control module 501 via transmission module 503. If the clarity indicates that the image captured by the camera is still unclear, the camera temperature detected by temperature sensor 3 is obtained. If the current camera temperature is -20°C, heating control module 501 continues to control heater 4 to heat lens 201 at a lower second heating temperature. This process repeats until the clarity indicates that the image captured by the camera is clear and free of interference, heating control module 501 continues to control heater 4 to heat lens 201 at a lower third heating temperature, maintaining the defrosted state.

[0068] In order to fix the camera module 2, temperature sensor 3 and circuit board 5, and protect the camera module 2, temperature sensor 3 and circuit board 5, please refer to Figure 1 The fixing assembly 1 includes a fixing connection base 101, a module fixing member 102 and a protective shell 103 detachably connected to the fixing connection base 101.

[0069] The module fixing member 102 is provided with a fixing hole, and the camera module 2 is disposed in the fixing hole.

[0070] The module fixing part 102, temperature sensor 3 and circuit board 5 can all be detachably mounted on the fixed connection seat 101, and the fixing hole of the module fixing part 102 faces the image capture module 502 so that light passing through the lens 201 of the camera module 2 can enter the image capture module 502.

[0071] A light hole is formed at one end of the protective shell 103 away from the fixed connection base 101 , and an accommodating cavity is formed inside the protective shell 103 so that the module fixing part 102 , the temperature sensor 3 and the circuit board 5 are all located in the accommodating cavity.

[0072] The protective housing 103 and the fixed connection base 101 can be fixed in a detachable manner, and the module fixing member 102 and the camera module 2 can also be detachably connected. The detachable connection method can include, but is not limited to: a screw 11 and a threaded hole, a pin and a socket, a threaded connection, and a buckle and a block connection. This is not limited in this embodiment.

[0073] Optionally, the fixed connection base 101, the circuit board 5, the protective shell 103, and the module fixing member 102 are all provided with threaded holes. The first set of screws 11 sequentially pass through the fixed connection base 101 and the protective shell 103 on the protective shell 103 to fix the fixed connection base 101 and the protective shell 103. The second set of screws 11 sequentially pass through the fixed connection base 101 and the circuit board 5 to fix the circuit board 5 to the fixed connection base 101. The third set of screws 11 sequentially pass through the fixed connection base 101 and the module fixing member 102 to fix the fixed connection base 101 and the module fixing member 102.

[0074] In order to make the camera work for a long time, a power supply mechanism is added. Figure 4 The circuit board 5 further includes a power supply module 504 , which supplies power to the temperature sensor 3 , the heating control module 501 , the transmission module 503 and the image capture module 502 .

[0075] The power module 504 may be composed of an energy storage component, for example, a lithium battery, a button battery lamp, etc.

[0076] In order to facilitate charging the power module 504 and connecting the transmission module 503 and the back-end controller 6, please refer to Figure 5 The fixed connection seat 101 is provided with a first connection hole and a second connection hole, and the camera further includes a power line 7 and a transmission line 8.

[0077] One end of the power line 7 passes through the first connection hole and is connected to the power module 504 , and the other end of the power line 7 is used to be connected to the power supply terminal.

[0078] One end of the transmission line 8 passes through the second connection hole and is connected to the transmission module 503 , and the other end of the transmission line 8 is used to be connected to the back-end controller 6 .

[0079] Among them, the transmission line 8 can be understood as a high-definition wiring harness, which can transmit the image capture information of the image capture module 502 to the back-end controller 6 in high-definition form, and the power line 7 can be understood as a heating wiring harness, which is used to provide power for the camera's defrosting, defogger heating functions and image capture functions.

[0080] Taking the application of the camera in a vehicle as an example, the power supply end can be the vehicle's power supply, and the back-end controller 6 can be the vehicle's in-vehicle entertainment terminal, SOC system and other equipment.

[0081] Furthermore, the transmission line 8 and the power line 7 can be wrapped with the same foam to protect the power line 7 and the transmission line 8 while reducing the foam cost.

[0082] In order to prevent the gap between the module fixing member 102 and the camera module 2 and improve the waterproof and dustproof performance, refer to Figure 6The fixing component 1 also includes a transparent protective ring 104, and the module fixing part 102 also includes a first sealing ring 9.

[0083] The transparent protective ring 104 is detachably disposed between the light hole of the protective shell 103 and the camera module 2. It should be understood that the transparent protective ring 104 abuts against the lens 201 closest to the object side in the camera module 2 to seal the gap between the lens 201 and the protective shell 103.

[0084] The first sealing ring 9 is disposed between the module fixing member 102 and the camera module 2 .

[0085] In order to reduce the influence of the transparent protective ring 104 and completely seal the gap between the lens 201 and the protective shell 103, the transparent protective ring 104 can be formed by injecting glue.

[0086] Similarly, in order to improve the waterproof performance of the camera, the camera can also include two second sealing rings, one second sealing ring is arranged between the first connecting hole and the power line 7, and the other second sealing ring is arranged between the second connecting hole and the transmission line 8.

[0087] The first sealing ring 9 and the second sealing ring can be, but are not limited to, glue, rubber pads, polyurethane sealing rings, fluororubber sealing rings, etc., which are not limited in this embodiment.

[0088] Further, refer to Figure 5 The camera may further include a third sealing ring 10, which is arranged at the connection between the protective shell and the fixed connecting seat 101 to seal the gap between the protective shell 103 and the fixed connecting seat 101, thereby improving the waterproof and dustproof performance of the camera.

[0089] Based on the same inventive concept as the above-mentioned camera, an embodiment of the present invention further provides a vehicle, comprising a vehicle body and the camera provided above, wherein the camera is arranged in the exterior rearview mirror area of the vehicle body.

[0090] For the specific implementation and effect of the camera, please refer to the above description and will not be repeated here.

[0091] In this case, the camera acts as a rearview mirror, monitoring the vehicle's surroundings and displaying images to assist the user in maneuvering the vehicle. Furthermore, in winter, and other frosty, icy, and foggy weather, the camera automatically activates heating to defrost, melt ice, and defog when temperatures drop too low. Once the image is clear and normal, it continues heating at a lower temperature to maintain defrosting, melting ice, and defogger functions. Heating stops only when the outside temperature returns to normal or the vehicle is turned off. This ensures the camera always captures a clear view of the surroundings while driving, assisting in environmental monitoring and improving driving safety.

[0092] The camera and vehicle provided by the present invention have at least the following advantages:

[0093] (1) The camera can quickly defrost, melt ice and defog, and ensure that the camera can capture clear images;
