The present embodiment provides a camera 100, as shown in fig. 1, the camera 100 includes a housing 1. The housing 1 has a cavity Q.

By way of example, the camera 100 may be an infrared light camera, a visible light camera, a laser camera, a 3D profiler, or the like.

The housing 1 is used for protecting functional components (e.g., circuit boards, etc.) disposed within the cavity Q of the housing 1, for example.

Illustratively, the material of the housing 1 includes plastic, metal, and the like.

The cost and weight of the plastic are small, and in the case that the material of the housing 1 is plastic, the manufacturing cost of the housing 1 can be reduced, and the weight of the housing 1 can be reduced.

The strength of the metal is high, and in the case where the material of the housing 1 is metal, the protection function of the housing 1 to the functional components in the cavity can be improved.

In some examples, as shown in fig. 1, the camera 100 further includes a plurality of components to be tempered 2, a plurality of temperature sensors 3, a plurality of thermoelectric cooling components 4, and a control component 5.

In some examples, a plurality of components 2 to be tempered are disposed within the cavity Q.

The temperature-regulating member 2 is a temperature-sensitive device, and needs to operate in a specific temperature range, and is prone to work failure when the temperature is too high or too low. Therefore, it is necessary to regulate the temperature of the temperature regulating member 2 when the camera 100 is operated.

For example, the temperature-to-be-adjusted component 2 includes: image sensors, image processors, lasers, double rate synchronous dynamic random access memory (commonly referred to as DDR), and light filling lamps, etc.

The number of components 2 to be tempered may be, for example, two, three or four, etc.

In fig. 2 and 3, the number of the components 2 to be tempered is taken as two, and the two components 2 to be tempered are denoted as a component 21 to be tempered and a component 22 to be tempered, respectively.

In some examples, as shown in fig. 1, a plurality of temperature sensors 3 are in one-to-one correspondence with a plurality of members to be tempered 2, and the temperature sensors 3 are provided on the corresponding members to be tempered 2. The temperature sensor 3 is used for detecting the temperature of the corresponding part 2 to be regulated and outputting an induction signal.

The temperature sensor 3 may be a thermocouple, for example.

The number of temperature sensors 3 may be, for example, two, three, four, or the like.

The number of temperature sensors 3 is illustratively the same as the number of components 2 to be tempered, one temperature sensor 3 being associated with each component 2 to be tempered.

For example, the number of the temperature-adjusting parts 2 is two, and the number of the temperature sensors 3 is also two; the number of the temperature-regulating components 2 is three, and the number of the temperature sensors 3 is also three; the number of the temperature-regulating components 2 is four, and the number of the temperature sensors 3 is also four; the number of temperature sensors 3 and the number of components 2 to be tempered may also be other numbers.

In fig. 2 and 3, the number of temperature sensors 3 is taken as two as an example, and the two temperature sensors 3 are respectively denoted by a temperature sensor 31 and a temperature sensor 32. The temperature sensor 31 is disposed on the temperature-adjusting member 21, and is configured to detect a temperature of the temperature-adjusting member 21 and output an induction signal; the temperature sensor 32 is disposed on the temperature-adjusting member 22, and is configured to detect a temperature of the temperature-adjusting member 22 and output an induction signal.

The above-mentioned induction signal may be, for example, a voltage signal.

For example, in case the temperature of the component 2 to be tempered is high, the corresponding temperature sensor 3 may output a high voltage; in case the temperature of the temperature regulating member 2 is low, the corresponding temperature sensor 3 may output a low voltage.

In some examples, as shown in fig. 1, the plurality of thermoelectric cooling components 4 are in one-to-one correspondence with the plurality of components to be temperature-regulated 2, and the thermoelectric cooling components 4 are disposed on the corresponding components to be temperature-regulated 2.

The thermoelectric refrigeration (Thermo Electric Cppler, abbreviated as TEC) component 4 can rapidly transfer heat from one surface to the other surface by forward power supply, and can locally heat up and cool down the component by reversing the heat transfer direction by reverse power supply.

Illustratively, the thermoelectric cooling element 4 comprises a thermoelectric cooling fin. The thermoelectric refrigerating sheet is a heat pump, and has the advantages of no sliding parts, and is applied to occasions with limited space, high reliability requirement and no refrigerant pollution. When the thermoelectric cooling sheet is powered on with direct current, heat transfer occurs between the two ends of the thermoelectric cooling sheet, and heat is transferred from one end to the other end.

Illustratively, the number of thermoelectric cooling elements 4 may be two, three, four, etc.

Illustratively, the number of thermoelectric cooling elements 4 is the same as the number of elements 2 to be tempered, one thermoelectric cooling element 4 being associated with each element 2 to be tempered.

For example, the number of the temperature-adjusting parts 2 is two, and the number of the thermoelectric cooling parts 4 is also two; the number of the temperature-regulating parts 2 is three, and the number of the thermoelectric refrigerating parts 4 is also three; the number of the temperature-regulating parts 2 is four, and the number of the thermoelectric refrigerating parts 4 is also four; the number of thermoelectric cooling elements 4 and the number of elements 2 to be tempered may also be other.

After the thermoelectric cooling component 4 is arranged on the component 2 to be temperature-regulated, one end of the thermoelectric cooling component 4 absorbs heat and the other end can release heat in the working process of the thermoelectric cooling component 4, so that the thermoelectric cooling component 4 can transfer and release the external heat absorbed by the thermoelectric cooling component to the component 2 to be temperature-regulated so as to heat the component 2 to be temperature-regulated, or the thermoelectric cooling component 4 can absorb the heat of the component 2 to be temperature-regulated and transfer and release the heat to the outside so as to cool the component 2 to be temperature-regulated, thereby realizing flexible regulation of the temperature of the component 2 to be temperature-regulated.

In fig. 2 and 3, the number of thermoelectric cooling elements 4 is two, and the two thermoelectric cooling elements 4 are respectively denoted by thermoelectric cooling element 41 and thermoelectric cooling element 42. The thermoelectric refrigeration component 41 is arranged on the component 21 to be regulated, and can regulate the temperature of the component 21 to be regulated; the thermoelectric cooling element 42 is disposed on the element 22 to be tempered, and can regulate the temperature of the element 22 to be tempered.

In some examples, as shown in fig. 1, a control component 5 is disposed within the cavity Q and coupled with the temperature sensor 3, the thermoelectric refrigeration component 4. The control part 5 is used for receiving the induction signal detected by the temperature sensor 3 and controlling the working state of the thermoelectric refrigeration part 4 corresponding to the temperature sensor 3 according to the induction signal.

Illustratively, the control component 5 may send a first control signal to the thermoelectric refrigeration component 4, and the thermoelectric refrigeration component 4 may receive the first control signal and be in an operating state; the control unit 5 may send a second control signal to the thermoelectric cooling unit 4, and the thermoelectric cooling unit 4 may receive the second control signal and be in a non-operating state.

For example, in the case where the thermoelectric cooling element 4 is in an operating state, heat at one end of the thermoelectric cooling element 4 may be transferred to the other end; when the thermoelectric cooling element 4 is in the non-operating state, the heat transfer between both ends thereof is stopped.

The control unit 5 may, for example, send the same control signal to different thermoelectric cooling units 4 or may send different control signals to different thermoelectric cooling units 4.

Through the arrangement, the control part 5 can control the working states of the thermoelectric refrigeration parts 4 according to the induction signals of the temperature sensors 3 arranged on the parts 2 to be regulated, can automatically control the temperatures of the parts 2 to be regulated with different temperature regulation requirements, and meets the requirements of different temperature control of the parts.

From this, the camera 100 that this application provided, including a plurality of temperature control parts 2 that wait, through setting up the temperature sensor 3 with a plurality of temperature control parts 2 one-to-one, can detect the temperature of corresponding temperature control parts 2 through temperature sensor 3, through setting up a plurality of thermoelectric refrigeration parts 4 and control part 5, and make control part 5 and temperature sensor 3, thermoelectric refrigeration part 4 couple, control part 5 can be according to the induction signal of temperature sensor 3 that sets up on a plurality of temperature control parts 2, control the operating condition of a plurality of thermoelectric refrigeration parts 4, therefore can carry out automatic control to the temperature of a plurality of temperature control parts 2 that wait of different temperature regulation demands, satisfy the demand of the different temperature control of a plurality of parts, avoid waiting to adjust temperature parts 2 because of the too high or too low normal operating condition that influences temperature control parts 2.

In some embodiments, as shown in fig. 3, the control section 5 includes a plurality of signal amplifiers 51 and signal comparators 52. The plurality of signal amplifiers 51 are in one-to-one correspondence with the plurality of temperature sensors 3, and the signal amplifiers 51 are coupled with the corresponding temperature sensors 3. The signal amplifier 51 is used for receiving the sensing signal and amplifying the sensing signal. The signal comparator 52 has a first input 52A, a second input 52B, and an output 52C. The first input 52A and the second input 52B are coupled to two different signal amplifiers 51, respectively, and the output 52C is coupled to the thermoelectric cooling element 4. The signal comparator 52 is configured to receive and compare the sensing signals amplified by the two signal amplifiers 51, and output a processing signal to the output terminal 52C according to the comparison result, so as to control the working state of the thermoelectric refrigeration component 4 corresponding to the temperature sensor 3 coupled to the two signal amplifiers 51.

The number of signal amplifiers 51 may be, for example, two, three, four, etc.

Illustratively, the number of signal amplifiers 51 is the same as the number of temperature sensors 3, one signal amplifier 51 being associated with each temperature sensor 3.

For example, the number of the temperature sensors 3 is two, and the number of the signal amplifiers 51 is also two; the number of the temperature sensors 3 is three, and the number of the signal amplifiers 51 is also three; the number of the temperature sensors 3 is four, and the number of the signal amplifiers 51 is also four; the number of signal amplifiers 51 and the number of temperature sensors 3 may be other numbers.

In fig. 3, the number of signal amplifiers 51 is two, and the two signal amplifiers 51 are respectively denoted by signal amplifier 511 and signal amplifier 512. The signal amplifier 511 is coupled to the temperature sensor 31, and is used for amplifying the sensing signal of the temperature sensor 31; the signal amplifier 512 is coupled to the temperature sensor 32 for amplifying the sensing signal of the temperature sensor 32.

For example, in the case where the above-described sense signal is a voltage signal, a voltage of 0.3V is outputted at the temperature sensor 3 and amplified to a voltage of 3V after passing through the signal amplifier 51; alternatively, the voltage of 0.3V is outputted from the temperature sensor 3 and amplified to a voltage of 6V after passing through the signal amplifier 51.

The amplification of the sense signal by the different signal amplifiers 51 may be the same or different, for example.

For example, a voltage of 0.3V output from the temperature sensor 31 is amplified to a voltage of 3V after passing through the signal amplifier 511, and the amplification factor of the signal amplifier 511 is 10; alternatively, the voltage of 0.3V output from the temperature sensor 32 is amplified to a voltage of 6V after passing through the signal amplifier 512, and the amplification factor of the signal amplifier 512 is 20.

The sensing signal of the temperature sensor 3 is small, and the sensing signal can be amplified and then transmitted to the signal comparator 52 by arranging the signal amplifier 51, so that the problem that the signal comparator 52 is difficult to identify because the sensing signal of the temperature sensor 3 is too small can be avoided.

A signal comparator (also referred to as a comparator) is an electronic component that outputs different voltage results at its output terminals by comparing the magnitudes of the currents or voltages at the two input terminals.

For example, the signal comparator 52 may compare the voltage signals input from the first input terminal 52A and the second input terminal 52B, and output a processing signal to the output terminal 52C according to the comparison result.

For example, in the case where the voltage input to the first input terminal 52A is 3V and the voltage input to the second input terminal 52B is 6V, the signal comparator 52 may output a high level signal to the output terminal 52C, and thus the processing signal output from the output terminal 52C is a high level signal; in the case where the voltage input to the first input terminal 52A is 6V and the voltage input to the second input terminal 52B is 3V, the signal comparator 52 may output a low level signal to the output terminal 52C, and thus the processing signal output from the output terminal 52C is a low level signal. The high-level signal is higher in voltage value than the low-level signal. For example, the high-level signal and the low-level signal are both dc voltage signals, the voltage value of the high-level signal is 5V, and the voltage value of the low-level signal is 0V. The high level signal and the low level signal described below are the same as the high level signal and the low level signal described herein.

For example, after the thermoelectric cooling element 4 receives the 5V dc voltage signal, the thermoelectric cooling element 4 is in a working state, so that the temperature of the plurality of elements 2 to be temperature-regulated can be controlled; after the thermoelectric cooling unit 4 receives the 0V dc voltage signal, the thermoelectric cooling unit 4 is in a non-operating state, and the temperature control of the plurality of temperature-to-be-controlled units 2 is stopped.

Through the arrangement, the sensing signals output by the temperature sensors 3 can be amplified by the signal amplifier 51 and then input into the signal comparator 52, so that the signal comparator 52 can compare the sensing signals output by different temperature sensors 3 and then output corresponding processing signals, and the working state of the thermoelectric refrigeration component 4 is directly controlled by the processing signals, thereby realizing the automatic control of the temperatures of a plurality of components 2 to be regulated. The structure can realize automatic control of temperature through hardware, can be suitable for a scene without software, and improves the application range of the camera 100.

In other examples, the first input 52A of the signal comparator 52 is coupled to one of the signal amplifiers 51, the second input 52B is coupled to a predetermined voltage terminal, and the signal comparator 52 compares the signal output from the signal amplifier 51 with the signal output from the predetermined signal terminal and outputs a processing signal to the output 52C according to the comparison result. The connection relationship between the two input terminals of the signal comparator 52 is not limited in this disclosure.

The signal output by the preset signal terminal may be a constant voltage direct current signal.

The operation of the signal comparator 52 and the thermoelectric cooling element 4 in this example is illustrated below.

For example, the voltage input to the first input terminal 52A is 3V, the voltage at the preset voltage terminal is 6V, that is, the voltage input to the second input terminal 52B is 6V, and the signal comparator 52 may output a high level signal to the output terminal 52C. After the thermoelectric cooling element 4 receives the 5V dc voltage signal, the thermoelectric cooling element 4 is in an operating state, so that the temperature of the element 2 to be temperature-adjusted corresponding to the first input end 52A can be controlled.

For example, the voltage input to the first input terminal 52A is 10V, the voltage at the preset voltage terminal is 6V, that is, the voltage input to the second input terminal 52B is 6V, and the signal comparator 52 may output a low level signal to the output terminal 52C. After the thermoelectric cooling unit 4 receives the 0V dc voltage signal, the thermoelectric cooling unit 4 is in a non-operating state, and the temperature control of the temperature-to-be-controlled member 2 corresponding to the first input terminal 52A is stopped.

Therefore, the signal output by the output end 52C of the signal comparator 52 can be controlled by adjusting the voltage of the preset signal end, so as to control the working state of the thermoelectric refrigeration component 4, and realize the control of the temperature of the component 2 to be regulated.

It should be noted that there are various ways to arrange the plurality of temperature adjustment members 2 in the camera 100, and the disclosure is not limited thereto.

In some embodiments, the plurality of components to be tempered 2 comprises only components to be heat dissipated.

In other embodiments, the plurality of components to be tempered 2 comprises only components to be heated.

In still other embodiments, the plurality of temperature-regulating members 2 include only members to be cooled during a certain operation stage of the camera 100, and the plurality of heat-regulating members are converted into members to be heated during another operation stage of the camera 100, which is not limited in the present disclosure.

In still other embodiments, referring to fig. 4, the plurality of temperature-adjusting components 2 includes at least one component 2a to be cooled and at least one component 2b to be heated, and the arrangement and operation of the thermoelectric cooling component 4 will be described below by taking this as an example.

As shown in fig. 4, the thermoelectric cooling member 4 has a cooling surface 4A and a heating surface 4B, the member to be heat-dissipated 2a is in contact with the cooling surface 4A of the thermoelectric cooling member 4, and the member to be heated 2B is in contact with the heating surface 4B of the thermoelectric cooling member 4.

Illustratively, in fig. 4, the thermoelectric cooling member 41 is provided corresponding to the member to be heat-dissipated 2a, and the thermoelectric cooling member 42 is provided corresponding to the member to be heated 2 b. When the processing signal output from the signal comparator 52 to the output terminal 52C is a high level signal, the thermoelectric cooling unit 41 and the thermoelectric cooling unit 42 operate. In the process of operating the thermoelectric refrigeration component 41, the thermoelectric refrigeration component 41 transmits heat of the refrigeration surface 4A to the heating surface 4B, so that the refrigeration surface 4A dissipates heat of the component 2a to be dissipated, and the temperature of the component 2a to be dissipated is reduced. During the operation of the thermoelectric cooling element 42, the thermoelectric cooling element 42 transfers heat from the cooling surface 4A to the heating surface 4B, thereby heating the heating surface 4B to the element 2B to be heated and raising the temperature of the element 2B to be heated.

Through the arrangement, the temperature of the temperature-adjusting component 2 to be adjusted can be automatically controlled by selecting the contact of the temperature-adjusting component 2 and the cooling surface 4A or the heating surface 4B of the thermoelectric cooling component 4 according to the type of the temperature-adjusting component 2, and the requirements of different temperature control of a plurality of temperature-sensitive devices are met.

In some embodiments, as shown in fig. 4, the output end 52C of one signal comparator 52 is coupled to the thermoelectric cooling element 41 corresponding to one element 2a to be cooled and the thermoelectric cooling element 42 corresponding to one element 2b to be heated, respectively.

For example, as shown in fig. 4, in the case that the cavity Q of the housing 1 of the camera 100 includes one to-be-cooled component 2a and one to-be-heated component 2b, the thermoelectric cooling component 41 may cool the to-be-cooled component 2a and transfer heat on the to-be-cooled component 2a into the cavity Q, so that air in the cavity Q is warmed; on this basis, the thermoelectric cooling element 42 transfers the heat of the cooling surface 4A to the heating surface 4B to heat the element 2B to be heated, so that the cooling surface 4A of the thermoelectric cooling element 42 can absorb the heat of the air in the cavity Q. The temperature in the cavity Q of the housing 1 of the camera 100 can be kept substantially balanced by the combined action of the thermoelectric cooling element 41 and the thermoelectric cooling element 42.

By the above arrangement, the control of the different temperature requirements of the two components 2 to be tempered can be achieved by one signal comparator 52 and the temperature in the cavity Q of the housing 1 of the camera 100 is kept substantially balanced.

In some embodiments, as shown in fig. 5, the number of signal comparators 52 is plural, and one thermoelectric cooling element 4 is coupled to the output terminals 52C of the plural signal comparators 52.

Illustratively, as shown in fig. 5, the plurality of components to be tempered 2 includes the components to be tempered 23, 24 and 25, the plurality of thermoelectric cooling components 4 includes the thermoelectric cooling components 43, 44 and 45, and the signal comparator 52 includes the signal comparator 521 and 522.

The temperature-to-be-adjusted component 23 is arranged corresponding to the thermoelectric cooling component 43, the temperature-to-be-adjusted component 24 is arranged corresponding to the thermoelectric cooling component 44, and the temperature-to-be-adjusted component 25 is arranged corresponding to the thermoelectric cooling component 45.

The signal amplifier 51 corresponding to the temperature-adjusting member 23 is coupled to the first input 52A of the signal comparator 521, the signal amplifier 51 corresponding to the temperature-adjusting member 25 is coupled to the second input 52B of the signal comparator 521, and the output 52C of the signal comparator 521 is coupled to the thermoelectric cooling member 43 and the thermoelectric cooling member 45. Thus, the signal comparator 521 can realize the temperature adjustment of the temperature-to-be-adjusted member 23 and the temperature-to-be-adjusted member 25.

The signal amplifier 51 corresponding to the temperature-adjusting component 24 is coupled to the first input 52A of the signal comparator 522, the signal amplifier 51 corresponding to the temperature-adjusting component 25 is coupled to the second input 52B of the signal comparator 522, and the output 52C of the signal comparator 522 is coupled to the thermoelectric cooling component 45 and the thermoelectric cooling component 44. Thus, the signal comparator 522 can realize the temperature adjustment of the temperature to-be-adjusted component 24 and the temperature to-be-adjusted component 25.

Through the arrangement, the thermoelectric cooling component 45 is respectively coupled with the output ends 52C of the signal comparator 521 and the signal comparator 522, and the working states of the thermoelectric cooling component 45 can be respectively controlled through the signal comparator 521 and the signal comparator 522, so that the signal comparator 52 can play a better role in regulating the temperature of the component 25 to be regulated.

In other embodiments, as shown in fig. 6, the control component 5 further includes a controller 53, the controller 53 being coupled to the output 52C and the plurality of thermoelectric cooling components 4. The controller 53 is configured to receive the processing signal output from the signal comparator 52, and output a control signal to the thermoelectric cooling element 4 corresponding to the temperature sensor 3 coupled to the two signal amplifiers 51.

Illustratively, the controller 53 includes a programmable logic controller (Programmable Logic Controller, simply referred to as a PLC).

The controller 53 may determine the temperature of each of the components 2 to be temperature-adjusted after receiving the processing signal output from the signal comparator 52, so as to output a control signal to the thermoelectric cooling component 4 corresponding to each of the components 2 to be temperature-adjusted, thereby controlling the temperature of the components 2 to be temperature-adjusted.

For example, when the temperature of the member to be temperature-adjusted 23 is high, a control signal may be output to the corresponding thermoelectric cooling member 43 to cause the thermoelectric cooling member 43 to radiate heat from the member to be temperature-adjusted 23; when the temperature of the temperature-to-be-adjusted member 23 is low, a control signal may be output to the corresponding thermoelectric cooling member 43 to cause the thermoelectric cooling member 43 to heat the temperature-to-be-adjusted member 23. Thereby, the complex temperature adjustment of the temperature-adjusting member 23 to be adjusted can be realized by heat radiation and then heating or by heat radiation and then heating.

Through the arrangement, the plurality of components 2 to be regulated in temperature can be controlled through the controller 53, and the complex temperature regulation requirement of the components 2 to be regulated in temperature is met.

The foregoing is merely a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art who is skilled in the art will recognize that changes or substitutions are within the technical scope of the present application.
