Description

Technical Field

[0001] This application relates to the field of surveillance technology, and more particularly to a camera. Background Technology

[0002] Cameras are usually equipped with speakers. When in use, the speakers can emit sound to warn others. The louder the sound emitted by the speakers, the better the warning effect.

[0003] In related technologies, the speaker is mounted along the height of the camera, meaning the speaker's sound-emitting surface faces to the side. The sound outlet is located on the top surface of the camera; therefore, the speaker's sound-emitting surface is perpendicular to the top surface of the camera where sound can be emitted. Consequently, the speaker's sound emission mode is side-emitting, resulting in a relatively low loudness. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a camera that can improve the loudness and frequency response of the speaker in the camera.

[0005] A first aspect of this application provides a camera, including a camera body and a speaker assembly. The camera body has a first surface, which may be the top surface of the camera body. It is understood that the top surface may refer to the surface away from the ground when the camera is mounted on a fixed post.

[0006] The speaker assembly includes a housing and a speaker. The housing is fixed to the camera body and located on the side containing the first surface. That is, the speaker is mounted on top of the camera. Cameras are often installed at a high position in applications, while the speaker is primarily used to emit sound for people, animals, etc., on the ground.

[0007] The housing has a mounting hole located on the side containing the first surface. The speaker has a sound-emitting surface, which is fixed within the mounting hole, with at least a portion of the sound-emitting surface protruding from the housing. Thus, the speaker can emit sound from the sound-emitting surface outwards from the housing.

[0008] There is a first angle between the sound-emitting surface and the first surface, that is, there is a first angle between the sound-emitting surface and the top surface, and the first angle is an acute angle, so the sound-emitting surface is set at an angle. Therefore, the sound emitted by the speaker propagates obliquely.

[0009] Compared to related technologies where the speaker's sound-emitting surface faces to the side but the camera's sound outlet is located on the top surface, in this application, at least a portion of the sound-emitting surface is exposed from the housing. Sound emitted from this exposed portion can be directly emitted from an angled direction, thus making the speaker's sound emission method closer to direct sound emission, thereby increasing the loudness of the sound emitted by the speaker. Therefore, compared to related technologies, this application can achieve approximately the same sound loudness using a lower-power speaker, without increasing the camera's cost due to the use of a higher-power speaker. Furthermore, the speaker has a better frequency response curve and the sound is not distorted.

[0010] Furthermore, the tilted horn has a smaller dimension along the height direction, which in turn makes the horn assembly smaller along the height direction, thereby reducing the size of the camera along the height direction.

[0011] Regarding the orientation of the mounting hole, in one possible implementation, the mounting hole is positioned facing the side containing the first surface. Therefore, when the speaker is mounted in the mounting hole, the speaker's sound-emitting surface faces upwards at an angle. In another possible implementation, the mounting hole is positioned facing the second surface, wherein the second surface is the surface of the camera body opposite to the first surface, that is, the bottom surface of the camera, i.e., the surface of the camera facing the ground.

[0012] In some embodiments of this application, the housing includes a fixed body and a shield. The fixed body is fixed to the camera body and has mounting holes. The shield is disposed on the fixed body and located on the side where the speaker's sound-emitting surface is located. There is a gap between the shield and the speaker, and the projection of the shield onto the fixed body covers a portion of the speaker. Thus, on the one hand, a cavity can be formed between the shield and the speaker. When sound is emitted from the speaker's sound-emitting surface, the sound can be reflected multiple times within this cavity before finally being emitted out of the camera. This multiple sound reflection process optimizes the frequency response curve. On the other hand, when the projection of the shield onto the fixed body covers a portion of the speaker, the sound emission is not affected by the shield covering the entire area of ​​the speaker, nor is the sound emitted directly without reflection due to the shield's projection not covering the speaker, thus preventing the acquisition of a better frequency response curve. Therefore, when the projection of the shield onto the fixed body covers a portion of the speaker, both a larger sound loudness and a better frequency response curve can be obtained. On the other hand, when the camera is installed outdoors, some rainwater will get on the housing in the event of rain. The shield covering part of the speaker can protect the covered area of ​​the speaker from rain.

[0013] In some embodiments of this application, the housing has a mounting surface with mounting holes, and a second included angle, wherein the second included angle is an acute angle, between the mounting surface and the first surface. Thus, the mounting surface is inclined relative to the first surface. Since the first surface serves as the top surface of the camera during application, and the top surface is typically parallel to the ground, it can also be understood that the mounting surface is inclined relative to the ground. When the camera is installed outdoors, rainwater will fall onto the mounting surface during rain. Because the mounting surface is inclined relative to the ground, the rainwater can flow from the mounting surface to the outside of the camera, thereby preventing rainwater from flowing back into the camera's interior.

[0014] In some embodiments of this application, the speaker assembly may include one or at least two speakers. When the speaker assembly includes at least two speakers, the at least two speakers include a first speaker and a second speaker, with the sound-emitting surfaces of the first speaker and the second speaker facing different sides. In this way, the first speaker and the second speaker can emit sound from different sides respectively. On the one hand, the sound louder is greater. On the other hand, the emitted sound is more uniform.

[0015] In some embodiments of this application, the mounting surface includes a first sub-mounting surface and a second sub-mounting surface. A first horn is fixed to the first sub-mounting surface, and a second horn is fixed to the second sub-mounting surface. The first and second sub-mounting surfaces are inclined from one end closer to the other towards the side opposite to the first surface. Since the first surface serves as the top surface of the camera during application, both the first and second sub-mounting surfaces face the top surface of the camera. In rainy conditions, rainwater will fall onto the first and second sub-mounting surfaces. When the first and second sub-mounting surfaces are inclined from one end closer to the other towards the side opposite to the first surface—that is, when the first and second sub-mounting surfaces are inclined downwards from the middle of the camera towards both ends—rainwater can be diverted to the outside of the camera and prevented from flowing back into the camera.

[0016] In some embodiments of this application, a drainage groove is provided on the mounting surface. This allows rainwater that falls on the mounting surface to drain out of the camera through the drainage groove, thus better preventing rainwater backflow.

[0017] Furthermore, the mounting surface is provided with at least two drainage channels, including a first drainage channel, a second drainage channel, and a third drainage channel arranged sequentially at intervals. The second drainage channel is located in the middle of the mounting surface, while the first and third drainage channels are located on opposite sides of the mounting surface. During heavy rain, water droplets may splash into the cavity between the mounting surface and the shield. The first, second, and third drainage channels on the mounting surface can drain the water droplets from the camera from three different locations, thereby better preventing water accumulation, i.e., better preventing rainwater backflow.

[0018] Furthermore, at least two drainage channels are connected to the mounting holes. This way, when heavy rain splashes into the cavity between the mounting surface and the shield, the water droplets splashed into the cavity can flow from the mounting holes into the drainage channels and be discharged from the camera.

[0019] In some embodiments of this application, the housing further includes a connector, through which the fixing body is fixed to the camera body. Regarding the connection method between the connector and the camera body, in one example, the connector and the camera body are connected by welding. Specifically, this can be achieved through ultrasonic welding. Exemplarily, the housing also includes a welding portion located between the connector and the camera body. This approach is low-cost and easy to operate.

[0020] In another possible implementation, the connector is connected to the camera body via fasteners. This makes the connector detachable from the camera body. The speaker is typically fixed to the mounting hole using adhesive or fasteners; therefore, when the speaker is damaged, the housing can be removed from the camera body, the damaged speaker removed, a new speaker installed in the mounting hole, and the housing with the new speaker fixed to the camera body. Compared to solutions requiring replacement of the entire speaker assembly when the speaker is damaged, this application offers lower repair costs.

[0021] In addition, the housing also includes a sealing ring, which is fixed between the connector and the camera body. This increases the sealing between the connector and the camera body, thereby increasing the sealing between the speaker assembly and the camera body.

[0022] Regarding the structure of the connection surface between the connector and the camera body, in one possible implementation, the connection surface is a plane. In another possible implementation, the connection surface is a stepped surface. This results in better sealing between the connector and the camera body.

[0023] In some embodiments of this application, the connector has a through hole, and the speaker assembly further includes a waterproof and breathable membrane covering the through hole. In this way, on the one hand, the waterproof performance of the waterproof and breathable membrane prevents moisture from seeping into the speaker assembly from the camera body. On the other hand, the breathability of the waterproof and breathable membrane maintains the air pressure balance between the inside and outside of the speaker assembly, reducing the impact of fog and dew on the speaker.

[0024] In some embodiments of this application, a groove is provided on the first surface, and the housing is fixed within the groove. By matching the dimensions of the housing along the camera height direction with the depth of the groove, the top surface of the housing can be made flush with or slightly lower than the first surface, thereby avoiding an increase in the height of the camera. Furthermore, this also enhances the aesthetics of the camera.

[0025] In some embodiments of this application, the first included angle and the second included angle are the same. The first included angle is the angle between the sound-emitting surface of the speaker and the first surface, and the second included angle is the angle between the mounting surface of the housing and the first surface. When the first included angle and the second included angle are the same, it indicates that the sound-emitting surface of the speaker and the mounting surface of the housing are parallel or coplanar. Therefore, the sound emitted by the sound-emitting surface of the speaker is not obstructed by the mounting surface, thereby further increasing the loudness of the sound emitted by the speaker.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] In this article, the term "and / or" simply describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural.

For example, "first target object" and "second target object," etc., are used to distinguish different target objects, not to describe a specific order of target objects.

[0040] Terms such as “connected” and “linked” are used to express the interconnection or interaction between different components, which may include direct connection or indirect connection through other components. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover non-exclusive inclusion, such as including a series of steps or units.

[0042] In the description of the embodiments in this application, unless otherwise stated, "multiple" means two or more. For example, multiple processing units means two or more processing units; multiple systems means two or more systems.

[0043] Cameras are usually equipped with speakers. When in use, the speakers can emit sound to warn others. The louder the sound emitted by the speakers, the better the warning effect.

[0044] In related technologies, the speaker is mounted along the height of the camera, meaning its sound-emitting surface faces to the side. The sound outlet is located on the top surface of the camera. Thus, the speaker's sound-emitting surface is perpendicular to the top surface of the camera where sound can be emitted. Therefore, the speaker's sound emission mode is side-emitting, resulting in a relatively low loudness. To achieve a higher loudness, a more powerful speaker is needed, which increases both the speaker's cost and the camera's cost.

[0045] Based on this, this application provides a camera 1, which can be a stand-alone camera, such as a bullet camera, a shotgun camera, or a dome camera. The camera 1 can also be integrated into an electronic device. In this scenario, the electronic device may further include a controller, which is electrically connected to the camera 1. The controller can be used to control the camera 1 to perform operations such as recording and uploading image information.

[0046] Electronic devices can include, for example, servers, consumer electronics, home electronics, automotive electronics, financial terminals, and communication electronics, and this application does not limit the scope of these. Illustrated, the aforementioned consumer electronics can be mobile phones, tablet computers, laptops, personal computers (PCs), personal digital assistants (PDAs), smart wearable products (e.g., smartwatches, smart bracelets), virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, drones, etc. Home electronics can be smart door locks, televisions, smart speakers, refrigerators, robot vacuum cleaners, etc. Automotive electronics can be car navigation systems, car displays, etc. Financial terminal products can be automated teller machines (ATMs), self-service electronic devices, etc. Communication electronic products can be servers, storage devices, radar, base stations, and other communication equipment.

[0047] For ease of description, such as Figure 1 As shown, three directions are defined here: X, Y and Z. X represents the length direction of camera 1, Y represents the width direction of camera 1, and Z represents the height direction of camera 1. The X, Y and Z directions are perpendicular to each other.

[0048] like Figure 1 As shown, camera 1 may include: camera body 100 and speaker assembly 200. The camera body 100 contains a lens (…). Figure 1 (Not shown in the image), the lens can acquire image information of the surrounding environment. The camera body 100 has a first surface 101, which may be the top surface of the camera body 100. It can be understood that the top surface may refer to the side surface away from the ground when the camera 1 is mounted on a fixed stake.

[0049] like Figure 2 and Figure 3 As shown, the speaker assembly 200 includes a housing 10 and a speaker 20. Figure 1 As shown, the housing 10 is fixed to the camera body 100 and located on the side where the first surface 101 is located. That is, the speaker 20 is mounted on the top of the camera 1. When in use, the camera 1 is often mounted at a high place, while the speaker 20 is mainly used to emit sound for people, animals, etc. on the ground.

[0050] like Figure 1As shown, the housing 10 has a mounting hole 111. The speaker 20 has a sound-emitting surface 21, which is fixed in the mounting hole 111 and at least a portion of the sound-emitting surface 21 protrudes from the housing 10. In this way, the speaker 20 can emit sound from the sound-emitting surface 21 to the outside of the housing 10.

[0051] like Figure 1 As shown, there is a first angle between the sound-emitting surface 21 and the first surface 101, that is, there is a first angle between the sound-emitting surface 21 and the top surface, and the first angle is an acute angle. Thus, the sound-emitting surface 21 is inclined. Therefore, the sound emitted by the speaker 20 propagates obliquely.

[0052] Compared to related technologies where the speaker's sound-emitting surface faces to the side but the camera's sound outlet is located on the top surface, in this embodiment, at least a portion of the sound-emitting surface 21 is exposed from the housing 10. Sound emitted from this exposed portion can be emitted directly from an angle, thus making the speaker 20's sound emission method closer to direct sound emission, thereby increasing the loudness of the sound emitted by the speaker 20. Therefore, compared to related technologies, this embodiment can achieve approximately the same sound loudness using a lower-power speaker 20, without increasing the cost of the camera 1 due to the use of a higher-power speaker 20. Furthermore, the speaker 20 has a better frequency response curve and the sound is not distorted. For example, this embodiment can achieve a frequency response greater than 95 dB within the audible range with lower power consumption.

[0053] In addition, such as Figure 1 As shown, the size of the tilted speaker 20 along the Z direction is smaller, and thus the size of the speaker assembly 200 along the Z direction is also smaller, thereby reducing the size of the camera 1 along the Z direction.

[0054] Regarding the placement of the speaker assembly 200, in one possible implementation, such as Figure 1 As shown, a groove 102 is provided on the first surface 101, and the housing 10 is fixed in the groove 102. By matching the Z-axis dimension of the housing 10 along the camera 1 with the depth of the groove 102 (the dimension along the Z-axis), the top surface of the housing 10 can be flush with or slightly lower than the first surface 101, thereby not increasing the height of the camera 1. In addition, it can also improve the aesthetics of the camera 1.

[0055] In another possible implementation, the horn assembly 200 is disposed on the first surface 101.

[0056] Regarding the orientation of the mounting hole 111, in one possible implementation, such as Figure 1 As shown, the mounting hole 111 is positioned facing the side where the first surface 101 is located. Therefore, when the speaker 20 is installed in the mounting hole 111, the sound-emitting surface 21 of the speaker 20 faces the side where the first surface 101 is located, that is, it faces obliquely upward.

[0057] In another possible implementation, the mounting hole 111 is disposed facing the second surface, wherein the second surface is the surface on the camera body 100 opposite to the first surface 101, that is, the bottom surface of the camera 1, that is, the surface of the camera 1 facing the ground.

[0058] like Figure 2 and Figure 3 As shown, the housing 10 includes a fixing body 11, a connecting body 13, and a shielding body 12. The fixing body 11 is fixed to the housing via the connecting body 13. Figure 1 The camera body 100 shown.

[0059] like Figure 2 As shown, the fixing body 11 includes a first plate 114, two second plates 115, and two connecting plates 116. The two second plates 115 are located on opposite sides of the first plate 114. The sides of each of the two second plates 115 have inwardly facing grooves 1151, which extend to the shield 12. The two connecting plates 116 are fixed within the two grooves 1151. A gap exists between the connecting plates 116 and the surface 201 of the speaker assembly 200, and a gap also exists between the connecting plates 116 and the surface 202 of the speaker assembly 200. The fixing body 11 can also be fixed to the shield 12 via the connecting plates 116. Figure 1 The camera body 100 shown is shown. Surface 201 can be the top surface of the speaker assembly 200, and surface 202 can be the bottom surface of the speaker assembly 200. The top surface of the speaker assembly 200 can refer to the surface away from the ground when the camera 1 is mounted on the fixed stake. Similarly, the bottom surface of the speaker assembly 200 can refer to the surface facing the ground when the camera 1 is mounted on the fixed stake.

[0060] like Figure 2As shown, the first plate 114 has mounting holes 111. A shield 12 is mounted on the fixed body 11. Specifically, the shield 12 can be located between the two second plates 115, and on the side where the sound-emitting surface 21 of the speaker 20 is located. There is a gap between the shield 12 and the speaker 20, and the projection of the shield 12 onto the fixed body 11 covers a portion of the speaker 20. In this way, on the one hand, a cavity can be formed between the shield 12 and the speaker 20. When sound is emitted from the sound-emitting surface 21 of the speaker 20, the sound can be reflected multiple times within this cavity before finally being emitted out of the camera 1. During the multiple sound reflections, the frequency response curve of the sound can be optimized. On the other hand, when the projection of the shield 12 onto the fixed body 11 covers a portion of the speaker 20, the sound emission will not be affected if the projection of the shield 12 onto the fixed body 11 covers the entire area of ​​the speaker 20, nor will the sound be emitted directly without reflection if the projection of the shield 12 onto the fixed body 11 does not cover the speaker 20, thus preventing the acquisition of a better frequency response curve. Therefore, when the projection of the shield 12 onto the fixed body 11 covers a portion of the speaker 20, both a greater sound volume and a better frequency response curve can be obtained. Furthermore, when the camera 1 is installed outdoors, some rainwater will splash onto the housing 10 during rain; the shield 12 covering a portion of the speaker 20 can protect the covered area of ​​the speaker 20 from rain.

[0061] Regarding the connection method between connector 13 and camera body 100, in one possible implementation, Figure 2 The connector 13 shown is Figure 1 The camera bodies 100 shown are connected by welding. Specifically, they can be connected by ultrasonic welding. For example, the housing 10 also includes a welding part located between the connector 13 and the camera body 100. This method is low-cost and easy to operate.

[0062] In another possible implementation, Figure 2 The connector 13 shown is Figure 1 The camera bodies 100 shown are connected by fasteners. Thus, the connector 13 is detachably connected to the camera body 100. The speaker 20 is typically fixed in the mounting hole 111 by adhesive or fasteners. Therefore, when the speaker 20 is damaged, the housing 10 can be removed from the camera body 100, the damaged speaker 20 can be removed, a new speaker 20 can be installed in the mounting hole 111, and the housing 10 with the new speaker 20 can be fixed back to the camera body 100. Compared to the solution where the entire speaker assembly 200 needs to be replaced when the speaker 20 is damaged, the repair cost of this embodiment is lower.

[0063] In addition, such as Figure 4As shown, the housing 10 also includes a sealing ring 14, which is fixed between the connector 13 and the camera body 100. This increases the sealing between the connector 13 and the camera body 100, thereby increasing the sealing between the speaker assembly 200 and the camera body 100.

[0064] Regarding the structure of the connection surface 15 between the connector 13 and the camera body 100, in one possible implementation, such as... Figure 5 As shown, connector 13 and Figure 1 The connecting surface 15 between the camera bodies 100 shown is a stepped surface. This results in better sealing between the connector 13 and the camera body 100. In another possible embodiment, such as... Figure 6 As shown, connector 13 and Figure 1 The connecting surface 15 between the camera bodies 100 shown is a plane.

[0065] like Figure 7 As shown, the connector 13 has a through hole 131, and the speaker assembly 200 also includes a waterproof and breathable membrane 16 covering the through hole 131. Thus, on the one hand, the waterproof performance of the waterproof and breathable membrane 16 can prevent water vapor from... Figure 1 The camera body 100 shown is inserted into the speaker assembly 200. On the other hand, the breathability of the waterproof and breathable membrane 16 can maintain the air pressure balance between the inside and outside of the speaker assembly 200, reducing the impact of fog and dew on the speaker 20.

[0066] like Figure 7 As shown, the housing 10 may further include components disposed on the connector 13 facing the direction of the connector 13. Figure 1 Positioning post 18 on one side of the camera body 100 shown. Figure 1 The camera body 100 shown has a positioning hole with the same position and size as the positioning post 18. Figure 1 (Not shown in the image), so that during the process of installing the speaker assembly 200 onto the camera body 100, the positioning post 18 can be used to position the speaker assembly 200.

[0067] like Figure 2 As shown, the housing 10 has a mounting surface 112, and a mounting hole 111 is provided on the mounting surface 112. The mounting surface 112 and the first surface 101 form a second included angle. It can be understood that the surface 201 of the speaker assembly 200 can be... Figure 1 The first surface 101 of the camera body 100 shown is parallel. Therefore, when the mounting surface 112 has a second angle with the first surface 101, it indicates that the mounting surface 112 also has a second angle α2 with the surface 201. The second angle α2 is an acute angle. Thus, the mounting surface 112 is inclined relative to the first surface 101 and the surface 201. Since the camera 1 is used... Figure 1 The first surface 101 shown serves as its top surface, which is typically parallel to the ground. Therefore, it can also be understood that the mounting surface 112 is inclined relative to the ground. When the camera 1 is installed outdoors, rainwater will fall onto the mounting surface 112 during rain. Since the mounting surface 112 is inclined relative to the ground, the rainwater can flow from the mounting surface 112 to the outside of the camera 1, thereby preventing rainwater from flowing back into the camera 1.

[0068] It is understandable that the sound outlet surface 21 of the speaker 20 and Figure 1 When the first surfaces 101 shown have a first included angle, such as Figure 5 As shown, the sound-emitting surface 21 of the speaker 20 and the surface 201 can also have a first included angle α1.

[0069] In some embodiments of this application, Figure 2 The sound outlet surface 21 of the speaker 20 shown is... Figure 1 The first included angle α1 between the first surfaces 101 shown is... Figure 2 The mounting surface 112 of the housing 10 shown is... Figure 1 The second included angle a2 between the first surfaces 101 shown is the same. Thus, the sound-emitting surface 21 of the speaker 20 and the mounting surface 112 of the housing 10 are parallel or coplanar. For example, the sound-emitting surface 21 may be lower than, higher than, or flush with the mounting surface 112. Therefore, the sound emitted by the sound-emitting surface 21 of the speaker 20 is not obstructed by the mounting surface 112, thereby further increasing the loudness of the sound emitted by the speaker 20. Specifically, the first included angle a1 and the second included angle a2 may be, for example, 10°, 16°, 20°, 30°, 40°, 50°, 60°, 70°, or 80°, etc.

[0070] Regarding the number of speakers 20 in the speaker assembly 200, in one possible implementation, the speaker assembly 200 may include one speaker 20. In another possible implementation, the speaker assembly 200 may include at least two speakers 20. When the speaker assembly 200 includes at least two speakers 20, the at least two speakers 20 include, for example: Figure 8 As shown and Figure 9 The first speaker 20a and the second speaker 20b are shown. The sound-emitting surfaces 21 of the first speaker 20a and the second speaker 20b face different sides. In this way, the first speaker 20a and the second speaker 20b can emit sound from different sides respectively. On the one hand, the sound is louder. On the other hand, the emitted sound is more uniform.

[0071] Furthermore, such as Figure 5 and Figure 8As shown, the mounting surface 112 includes a first sub-mounting surface 1121 and a second sub-mounting surface 1122. A first horn 20a is fixed to the first sub-mounting surface 1121, and a second horn 20b is fixed to the second sub-mounting surface 1122. The first sub-mounting surface 1121 and the second sub-mounting surface 1122 extend from one end closer to the other towards the other, moving away from each other. Figure 1 The first surface 101 shown is tilted to one side. Since the first surface 101 serves as the top surface of the camera 1 during application, both the first sub-mounting surface 1121 and the second sub-mounting surface 1122 face the top surface of the camera 1. In rainy conditions, rainwater will fall onto the first sub-mounting surface 1121 and the second sub-mounting surface 1122. When the first sub-mounting surface 1121 and the second sub-mounting surface 1122 tilt away from the first surface 101 from their respective ends, i.e., when they tilt downwards from the middle of the camera 1 towards both ends, rainwater can be drained from the camera 1 without flowing back into its interior.

[0072] like Figure 3 As shown, a drainage groove 113 is provided on the mounting surface 112. This allows rainwater that falls on the mounting surface 112 to drain out of the camera 1 through the drainage groove 113, thus better preventing rainwater backflow. The depth of the drainage groove 113 can be 1.05 mm.

[0073] Furthermore, such as Figure 3 As shown, the mounting surface 112 is provided with at least two drainage grooves 113 arranged at intervals. Specifically, as... Figure 8 As shown, both the first sub-mounting surface 1121 and the second sub-mounting surface 1122 are provided with at least two drainage channels 113. For example, both the first sub-mounting surface 1121 and the second sub-mounting surface 1122 are provided with three parallel drainage channels 113. Exemplarily, the three drainage channels 113 include a first drainage channel 113a, a second drainage channel 113b, and a third drainage channel 113c. The second drainage channel 113b is located in the middle of the mounting surface 112, and the first drainage channel 113a and the third drainage channel 113c are located on both sides of the mounting surface 112. When it rains heavily, water droplets may splash into the cavity between the mounting surface 112 and the shield 12. The first drainage channel 113a, the second drainage channel 113b, and the third drainage channel 113c provided on the mounting surface 112 can discharge water droplets from the camera 1 from three different positions, thereby better preventing water accumulation, that is, better preventing rainwater backflow.

[0074] Moreover, such as Figure 3As shown, at least two drainage channels 113 are connected to the mounting hole 111. When a large droplet splashes into the cavity between the mounting surface 112 and the shield 12, the water droplets splashed into the cavity can flow from the mounting hole 111 to the drainage channel 113 and be discharged from the camera 1.
