Description

Technical Field

[0001] The present application belongs to the field of camera technology, and specifically relates to a camera device. Background Art

[0002] The camera device can be placed outdoors to detect the surrounding environment, but on rainy days or when the temperature difference is large, the lens of the camera device is prone to fogging, which can easily affect the shooting effect of the camera device. Taking the camera device used to realize vehicle-mounted assisted driving as an example, the camera device is usually installed at the rear of the vehicle to realize the automatic parking function. If the lens of the camera device is fogged, it will easily affect the automatic parking function of the vehicle.

[0003] There are two types of defogger methods for camera devices: active and passive. Passive defogger usually uses a desiccant or opens a vent on the camera device to eliminate highly saturated water vapor, but the defogger effect of this method is limited. Active defogger usually uses a heating structure to increase the temperature of the lens to achieve the effect of removing water mist, but the heating structure is usually installed on the outside of the camera device, which easily leads to a larger size of the entire camera device, and the heating structure is usually a heating film covering the front of the lens, which to a certain extent easily affects the imaging effect of the camera device.

[0004] In summary, the camera device involved in the related art has the problem of being unable to ensure the imaging effect on the basis of controlling its own volume. Utility Model Content

[0005] The present application discloses a camera device to solve the problem that the camera device involved in the related art cannot ensure the imaging effect on the basis of controlling its own volume.

[0006] In order to solve the above technical problems, this application adopts the following technical solutions:

[0007] A camera device includes a housing, a photosensitive chip, a lens barrel, a lens and a heating element.

[0008] The housing has a first inner cavity, the photosensitive chip and at least part of the lens barrel are both arranged in the first inner cavity, the lens barrel has a second inner cavity, the lens is arranged in the second inner cavity, and the lens is arranged opposite to the photosensitive chip;

[0009] The heating element is arranged in the second inner cavity, and the heating element is located outside the field of view of the lens.

[0010] The technical solution adopted in this application can achieve the following beneficial effects:

[0011] In the present application, since the lens barrel has a second inner cavity, and the lens and the heating element are arranged in the second inner cavity, the heating element can directly remove the water mist on the lens. It can be seen that the present application integrates the heating element in the lens barrel, that is, in the camera device, which can reduce the volume of the camera device to a certain extent. At the same time, since the heating element is located outside the field of view of the lens, the heating element will not block the lens, and thus will not affect the imaging effect of the camera device. Therefore, the camera device disclosed in the present application can solve the problem that the camera device involved in the related art cannot ensure the imaging effect on the basis of controlling its own volume.

[0038] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] The camera device disclosed in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0040] Please refer to Figure 1-Figure 18 The present application discloses a camera device, which includes a housing 100 , a photosensitive chip, a lens barrel 200 , a lens 300 and a heating element 400 .

[0041] The camera device disclosed in the present application can be installed indoors or outdoors to facilitate the detection of the surrounding environment. It can also be installed on the vehicle body and powered by a vehicle-mounted power supply or other specially provided power supply to facilitate the realization of vehicle-mounted assisted driving functions. For example, when the camera device is installed on both sides of the vehicle body, the camera device can be used as a streaming media exterior rearview mirror. Since the size of the camera device is usually small, this can reduce wind resistance to a certain extent. At the same time, the picture taken by the streaming media exterior rearview mirror is clearer and the shooting angle of view is wider, so that the streaming media exterior rearview mirror can more clearly display the scene behind the side of the vehicle, so that the driver can accurately obtain the conditions of the environment around the vehicle body.

[0042] When the camera device is installed at the rear of the vehicle body, at this time, the camera device is a camera device for realizing the automatic parking function of the vehicle. The camera device can be specifically installed on the bumper at the rear of the vehicle body. The camera device can capture the image behind the vehicle body in real time and transmit the captured image to the central rearview mirror, so that the vehicle driver can observe the real situation behind the vehicle from the perspective of the camera device. At the same time, during the automatic parking process, the camera device monitors the environment at the rear of the vehicle body in real time, and cooperates with the reversing radar and other sensors arranged around the vehicle body to scan and find a suitable parking space. Once a suitable space is found, the vehicle system will calculate the best parking path, and control the steering, acceleration and braking systems through the vehicle's electronic control unit to achieve precise automatic parking operations. It can be seen that the camera device plays a particularly important role in the automatic parking operation.

[0043] The housing 100 is a basic component of the camera device, which can provide a mounting base for other components of the camera device, such as providing a mounting base for the photosensitive chip and the lens barrel 200. Specifically, the housing 100 has a first inner cavity 110, in which at least a portion of the photosensitive chip and the lens barrel 200 are disposed, and the lens barrel 200 has a second inner cavity 210, in which a lens 300 is disposed, and the lens barrel 200 can protect the lens 300, and the lens 300 is disposed opposite to the photosensitive chip, and the photosensitive chip can capture the light passing through the lens 300 and convert it into an electronic signal, and finally form a captured image.

[0044] The heating element 400 has a heating function, and the heating element 400 is arranged in the second inner cavity 210, that is, the heating element 400 and the lens 300 are integrated in the lens barrel 200, so that the heating element 400 can heat the lens 300, thereby quickly eliminating the fog inside and outside the lens 300, thereby making the image captured by the camera device clearer, and the heating element 400 is located outside the field of view of the lens 300 to avoid the heating element 400 affecting the amount of light entering the lens 300, thereby avoiding affecting the shooting effect of the camera device. It can be seen that the camera device disclosed in the present application can quickly eliminate the fog inside and outside the lens 300, which enables the camera device used in the above-mentioned automatic parking scene to capture a clearer picture in real time.

[0045] Optionally, the heating element 400 may include a metal wire and a protective film wrapped around the metal wire. The protective film can conduct heat, and the heat generated by the metal wire can be transferred to the protective film. The protective film can conduct the heat to the second inner cavity 210 and then to the lens 300 to remove water mist on the lens 300.

[0046] In the present application, since the lens barrel 200 has a second inner cavity 210, and the lens 300 and the heating element 400 are arranged in the second inner cavity 210, the heating element 400 can directly remove the water mist on the lens 300. It can be seen that the present application integrates the heating element 400 in the lens barrel 200, that is, in the camera device, which can reduce the volume of the camera device to a certain extent. At the same time, since the heating element 400 is located outside the field of view of the lens 300, the heating element 400 will not block the lens 300, and thus will not affect the imaging effect of the camera device. Therefore, the camera device disclosed in the present application can solve the problem that the camera device involved in the related art cannot ensure the imaging effect on the basis of controlling its own volume.

[0047] In addition, since the present application effectively reduces the volume of the camera device and has a high space utilization rate, the camera device disclosed in the present application can be conveniently installed at the rear of the vehicle body, and the production cost of the camera device disclosed in the present application is low. In addition, since the present application integrates the heating element 400 into the camera device, this effectively reduces the waste of heat energy and improves the defogging efficiency, and the present application does not limit the design of the peripheral structure of the camera device.

[0048] Optionally, the heating element 400 may be a heating block of a smaller size, and the heating element 400 may be disposed on one side of the lens 300 .

[0049] In another embodiment, please refer to Figures 1 to 4The heating element 400 is a ring-shaped element, and the heating element 400 is arranged around the lens 300. At this time, the size of the heating element 400 is larger, and thus the heating area is larger, so that all parts of the lens 300 can be heated evenly, and the defog efficiency of the lens 300 is higher, that is, this arrangement can fully heat the lens 300.

[0050] Optionally, the heating element 400 may be electrically connected to other power sources outside the camera device through a conductive wire, that is, other power supply structures that can supply power to the heating element 400 are provided on the periphery of the camera device.

[0051] In another embodiment, please refer to Figures 1 to 3 The camera device may further include a circuit board 500 and a first conductive line 610 which are electrically connected. The circuit board 500 is disposed in the first inner cavity 110. For details, please refer to Fig.11 and Fig.12 The circuit board 500 may be provided with guide holes 510 and mounting holes 520 at intervals, and a guide column may be protruding from the inner wall of the shell 100 (specifically, it may be the inner wall of the second shell 140 described later), and the guide column is guided and matched with the guide hole 510. One end of the third connecting member 860 may pass through the mounting hole 520 and be connected to the inner wall of the shell 100, so that the circuit board 500 can be installed in the first inner cavity 110.

[0052] The photosensitive chip is arranged on the circuit board 500, and the circuit board 500 is the main power supply structure of the camera device, that is, the circuit board 500 can ensure that the camera device can work normally. The housing 100 (specifically, it can be the second housing 140 described later) is provided with a first threading hole 120 connected to the first inner cavity 110, and the lens barrel 200 is provided with a second threading hole 220 connected to the second inner cavity 210. One end of the first conductive wire 610 passes through the first inner cavity 110 and passes through the first threading hole 120 and the second threading hole 220 in sequence, and is electrically connected to the heating element 400. The other end of the first conductive wire 610 is electrically connected to the circuit board 500, so that the circuit board 500 can supply power to the heating element 400.

[0053] In this embodiment, the heating element 400 is electrically connected to the circuit board 500 in the camera device through the first conductive wire 610, which can simplify the structural complexity of the camera device while making full use of the existing circuit board 500 of the camera device, and this embodiment does not require an additional power supply structure. At the same time, since part of the first conductive wire 610 is arranged in the first inner cavity 110 and is electrically connected to the heating element 400 through the first threading hole 120 that passes through the outer shell 100 (specifically, it can be the second shell 140 described later) and the second threading hole 220 that passes through the lens barrel 200, that is, the first conductive wire 610 basically does not occupy additional space, so the volume of the camera device can be reduced.

[0054] Optionally, refer to Figures 1 to 3 The camera device may further include a temperature detection component 700 and a control component. The temperature detection component 700 may be a component having a temperature detection function such as a temperature sensor. The temperature detection component 700 is used to detect the temperature of the lens 300. The temperature detection component 700 is disposed in the second inner cavity 210. The control component is electrically connected to the temperature detection component 700 and the heating component 400, respectively. When the temperature of the lens 300 is less than the first preset temperature threshold, that is, when the temperature detected by the temperature detection component 700 is less than the first preset temperature threshold, the control component may control the heating component 400 to be in a power-on state, that is, control the heating component 400 to start heating; when the temperature of the lens 300 is greater than the second preset temperature threshold, that is, when the temperature detected by the temperature detection component 700 is greater than the second preset temperature threshold, the control component may control the heating component 400 to be in a power-off state, that is, control the heating component 400 to stop heating, wherein the first preset temperature threshold may be less than the second preset temperature threshold.

[0055] Specifically, in this embodiment, when the temperature detected by the temperature detection member 700 is less than the first preset temperature threshold, it means that the temperature of the lens 300 is low, which makes the water vapor inside and outside the lens barrel 200 easily condense on the lens 300. At this time, the control member can control the first conductive wire 610 to be energized, and then control the heating member 400 to start heating, so as to heat the lens 300 and directly play a role of defog; when the temperature detected by the temperature detection member 700 is greater than the second preset temperature threshold, it means that the temperature of the lens 300 is high, and the water mist on the lens 300 has been removed, so the control member can control the first conductive wire 610 to be de-energized, so that the heating member 400 stops heating, thereby reducing energy consumption and avoiding excessive temperature of the camera device. Of course, the camera device may not include the temperature detection member 700 and the control member.

[0056] Optionally, the temperature detection element 700 may be electrically connected to other power sources outside the camera device through a conductive wire, that is, other power supply structures that can supply power to the temperature detection element 700 are provided on the periphery of the camera device.

[0057] In another embodiment, please refer to Figures 1 to 3The camera device further includes a second conductive wire 620 electrically connected to the circuit board 500, one end of the second conductive wire 620 can be electrically connected to the temperature detection member 700, and the other end of the second conductive wire 620 can be electrically connected to the circuit board 500, so that the circuit board 500 can supply power to the temperature detection member 700. In this embodiment, the temperature detection member 700 is electrically connected to the circuit board 500 in the camera device through the second conductive wire 620, which can simplify the structural complexity of the camera device while making full use of the existing circuit board 500 of the camera device, and this embodiment does not need to set up an additional power supply structure, and the second conductive wire 620 basically does not occupy additional space, so the volume of the camera device can be reduced.

[0058] Optionally, during the process of electrically connecting the circuit board 500 and the temperature detection component 700, one end of the second conductive wire 620 can pass through the outer shell 100 (specifically, the second shell 140 described later) and other threading holes opened on the lens barrel 200 in sequence, and then be electrically connected to the temperature detection component 700. That is, at this time, at least two threading holes are opened on the outer shell 100 and the lens barrel 200.

[0059] In another embodiment, one end of the second conductive wire 620 passes through the first threading hole 120 and the second threading hole 220 in sequence and is electrically connected to the temperature detection element 700. That is, in this embodiment, the first conductive wire 610 and the second conductive wire 620 share the same first threading hole 120 and the same second threading hole 220. At this time, there is no need to open too many threading holes on the outer shell 100 and the lens barrel 200 to avoid affecting the overall sealing and structural strength of the camera device.

[0060] Optionally, the temperature detection member 700 is in contact with the heating member 400, so that the temperature detection member 700 can indirectly detect the temperature of the lens 300 through the heating member 400, that is, the setting position of the temperature detection member 700 is close to the setting position of the heating member 400, which enables the temperature detection member 700 to directly detect the temperature of the heating member 400, and then the temperature of the lens 300 can be obtained more accurately, so that the temperature control accuracy of the lens 300 of the present application is higher. At the same time, the temperature detection member 700 does not need to be too close to the lens 300, and it is not easy to affect the installation and operation of the lens 300. Of course, the temperature detection member 700 may not be in contact with the heating member 400, that is, the temperature detection member 700 and the heating member 400 can be arranged in the second inner cavity 210 at intervals.

[0061] Optionally, the housing 100 may include a first shell 130 and a second shell 140 connected in sequence, that is, the first shell 130 and the second shell 140 enclose a first inner cavity 110, the photosensitive chip and the circuit board 500 are both disposed in the second shell 140, and the lens barrel 200 is connected to the second shell 140 so that a part of the lens barrel 200 is disposed in the first inner cavity 110, and another part of the lens barrel 200 is disposed outside the first inner cavity 110, that is, at this time, part of the first conductive wire 610 is placed in the external environment.

[0062] In another embodiment, please refer to Figures 4 to 6 The housing 100 may further include a third housing 150, the first housing 130, the second housing 140 and the third housing 150 are connected in sequence, the lens barrel 200 may be connected to the third housing 150, that is, the third housing 150 may surround another part of the lens barrel 200 and the first conductive wire 610, and the third housing 150 is provided with an opening, the lens 300 faces the opening, so that the third housing 150 does not affect the normal shooting operation of the camera device, and the third housing 150 may protect the lens barrel 200 and the first conductive wire 610 to ensure the stability of the power supply from the first conductive wire 610 to the heating element 400. Optionally, when the camera device includes the above-mentioned temperature detection element 700 and the second conductive wire 620 that supplies power to the temperature detection element 700, the third housing 150 may also protect the temperature detection element 700 and the second conductive wire 620 to ensure the stability of the power supply from the second conductive wire 620 to the temperature detection element 700.

[0063] Optionally, the camera device may further include at least one of a first seal 810, a second seal 820, and a third seal 830, wherein:

[0064] The first sealing member 810 is sleeved outside the lens barrel 200, and the first sealing member 810 is sealed with the lens barrel 200 and the inner wall of the third housing 150. For details, please refer to Figures 1 to 4 and Figure 7 A limiting groove 230 can be provided on the lens barrel 200, and the first sealing member 810 is sleeved on the outside of the lens barrel 200, and a part of the first sealing member 810 is arranged in the limiting groove 230, so that the limiting groove 230 can limit the first sealing member 810, and the first sealing member 810 is sealed with the inner walls of the lens barrel 200 and the third shell 150 to prevent water vapor from entering the third shell 150 through the opening of the third shell 150, and entering the lens barrel 200 and the second shell 140 through the first threading hole 120 and the second threading hole 220. That is, this arrangement can prevent water vapor from corroding the circuit board 500, the heating element 400 and other electronic components of the camera device.

[0065] Optionally, to further ensure the stability of the setting of the first sealing member 810, the first sealing member 810 can be sleeved outside the lens barrel 200, and the two can be connected by bonding with a first adhesive. Of course, the purpose of connection can also be achieved by welding. At this time, since the first sealing member 810 is relatively stably installed on the lens barrel 200, when the lens barrel 200 is matched with the third shell 150, the first sealing member 810 can stably perform the sealing function and have a better overall sealing effect.

[0066] Please refer to Figure 3 , Figure 4 , Fig.15 and Fig.18 The second seal 820 is disposed between the first shell 130 and the second shell 140, and the second seal 820 is sealed with the first shell 130 and the second shell 140 to prevent water vapor from entering the first inner cavity 110, that is, the second seal 820 can also prevent water vapor from corroding the circuit board 500 and other electronic components of the camera device.

[0067] Please refer to Figure 3 , Figure 4 , Fig.10 and Fig.13 The third sealing member 830 is disposed between the second shell 140 and the third shell 150, and the third sealing member 830 is sealed with the second shell 140 and the third shell 150 to prevent water vapor from entering the second shell 140 and the third shell 150, and entering the lens barrel 200 and the second shell 140 through the first threading hole 120 and the second threading hole 220. That is, this arrangement can prevent water vapor from corroding the circuit board 500 and the heating element 400.

[0068] Of course, the camera device may not include the first sealing member 810 , the second sealing member 820 and the third sealing member 830 .

[0069] Optionally, when the camera device includes the first seal 810, the second seal 820 and the third seal 830 at the same time, the camera device can achieve a higher level of IP protection effect, for example, it can ensure that the camera device can meet the airtight requirements of IP67 and above, so that the camera device can cope with a relatively harsh environment, that is, this setting method makes the camera device more reliable. It can be seen that the present application can ensure the sealing of the camera device by adding the first seal 810, the second seal 820 and the third seal 830, thereby ensuring that the camera device can always work normally.

[0070] Optionally, the materials used to make the first seal 810, the second seal 820 and the third seal 830 can all be silicone, that is, the first seal 810, the second seal 820 and the third seal 830 are all silicone sealing rings. The silicone sealing rings have a certain degree of softness. Therefore, during specific use, the first seal 810, the second seal 820 and the third seal 830 can be squeezed to achieve a sealing effect.

[0071] Optionally, refer to Fig.14 , Fig.15 and Fig.18 In order to facilitate the installation of the second sealing member 820, a first limiting portion is protruded from the first housing 130. In order to avoid other structures, for example, to avoid the through hole 160 opened on the first housing 130 later, the first limiting portion is usually a special-shaped limiting portion, that is, a first special-shaped limiting portion 131 is protruded from the first housing 130. Correspondingly, the second sealing member 820 is also a special-shaped member. The second sealing member 820 can be sleeved outside the first special-shaped limiting portion 131 to ensure the installation stability of the second sealing member 820. Of course, the first housing 130 may not be protruded with the first special-shaped limiting portion 131.

[0072] Optionally, in order to further ensure the stability of the setting of the second seal 820, the second seal 820 can be sleeved outside the first special-shaped limiting portion 131, and the two can be connected by a second adhesive. Of course, the purpose of connection can also be achieved by welding. At this time, since the second seal 820 is relatively stably installed on the first special-shaped limiting portion 131, and then stably installed on the first shell 130, therefore, when the first shell 130 and the second shell 140 are matched, the second seal 820 can stably play a sealing role and has a better overall sealing effect.

[0073] Optionally, the first special-shaped limiting portion 131 may be provided with a first notch 132, and the second sealing member 820 may be provided with a first protrusion 821, which may protrude toward the inner side of the second sealing member 820, and the first protrusion 821 is arranged in the first notch 132 to form a foolproof structure, that is, the foolproof structure can ensure that the second sealing member 820 is installed in the correct position to prevent operators from making mistakes during the assembly process. Of course, the first special-shaped limiting portion 131 may not be provided with the first notch 132, and the second sealing member 820 may not be provided with the first protrusion 821.

[0074] Optionally, the camera device may further include a cable 900, see Figure 3 , Figure 4 , Fig.11 , Fig.13 , Fig.16 and Fig.18A first plug terminal 910 is provided at the first end of the cable 900. The first end of the cable 900 passes through the first shell 130 and enters the first inner cavity 110. The first plug terminal 910 is plugged into and matched with the second plug terminal 530 on the circuit board 500. The other end of the cable 900 is used to be electrically connected to an external power supply, which can be the above-mentioned vehicle-mounted power supply, that is, the external power supply can supply power to the circuit board 500 through the cable 900. The cable 900 can ensure the electrical connection stability between the cable 900 and the circuit board 500 through the plugging force between the first plug terminal 910 and the second plug terminal 530.

[0075] In a further optional embodiment, please refer to Figure 3 , Figure 4 , Fig.16 and Fig.18 , a mounting portion 920 is protruding from the cable 900, and the mounting portion 920 is mounted on the first housing 130 through the first connector 840, that is, at this time, the cable 900 can be stably mounted on the first housing 130, thereby further ensuring the electrical connection stability between the cable 900 and the circuit board 500. Of course, the mounting portion 920 may not be provided on the cable 900.

[0076] Optionally, the connector connecting the first shell 130 and the second shell 140 and the connector connecting the second shell 140 and the third shell 150 of the present application may be different connectors.

[0077] In another embodiment, please refer to Figure 4 and Fig.18 The camera device may further include a second connecting member 850. A through hole 160 is provided on the first shell 130 and the second shell 140, that is, a through hole penetrating the first shell 130 and the second shell 140 is provided on the first shell 130 and the second shell 140. The third shell 150 is provided with a connecting hole 170. One end of the second connecting member 850 passes through the through hole 160 and is connected to the connecting hole 170. That is, in this embodiment, the connecting member connecting the first shell 130 and the second shell 140 and the connecting member connecting the second shell 140 and the third shell 150 are the same connecting member, that is, the same second connecting member 850 is used to simultaneously connect the first shell 130, the second shell 140 and the third shell 150. This can simplify the connection complexity while reducing the number of connecting members, that is, simplify the installation method, and by reducing the number of second connecting members 850, the volume of the camera device can be indirectly reduced to a certain extent, that is, the volume of the camera device disclosed in the present application is smaller. Optionally, the number of the second connecting members 850 used in the present application may be 4, and the second connecting members 850 may be arranged at intervals. Of course, the embodiment of the present application does not impose any specific limitation on this.

[0078] Optionally, refer to Figures 1 to 4 , Fig. 9 , Fig.10 and Fig.13 In order to facilitate the installation of the third sealing member 830, a second limiting portion is protruded from the second housing 140. In order to avoid other structures, for example, to avoid the through hole 160 provided on the second housing 140, the second limiting portion is usually a special-shaped limiting portion, that is, a second special-shaped limiting portion 141 is protruded from the second housing 140. Correspondingly, the third sealing member 830 is also a special-shaped member. The third sealing member 830 can be sleeved outside the second special-shaped limiting portion 141 to ensure the installation stability of the third sealing member 830. Of course, the second housing 140 may not be protruded with the second special-shaped limiting portion 141.

[0079] Optionally, in order to further ensure the stability of the setting of the third seal 830, the third seal 830 can be sleeved outside the second special-shaped limiting portion 141, and the two can be connected by a third adhesive. Of course, the purpose of connection can also be achieved by welding. At this time, since the third seal 830 is relatively stably installed on the second special-shaped limiting portion 141, and then stably installed on the second shell 140, therefore, when the second shell 140 and the third shell 150 are matched, the third seal 830 can stably play a sealing role and has a better overall sealing effect.

[0080] Optionally, the second special-shaped limiting portion 141 may be provided with a second notch 142, and the third sealing member 830 may be provided with a second protrusion 831, which may protrude toward the inner side of the third sealing member 830, and the second protrusion 831 is arranged in the second notch 142 to form a foolproof structure, that is, the foolproof structure can ensure that the third sealing member 830 is installed in the correct position to prevent operators from making mistakes during assembly. Of course, the second special-shaped limiting portion 141 may not be provided with a second notch 142, and the third sealing member 830 may not be provided with a second protrusion 831.
