[0002] A wireless bullet camera is a device that converts optical image signals into electrical signals for recording. It mainly uses camera devices to convert light signals into electrical signals, then into digital video signals, which are amplified by a preamplifier circuit, processed and adjusted by various circuits, and then sent to recording media such as video recording for storage and playback.

[0003] In the field of hoisting, hoisting workers are often affected by factors such as height and environment, which can cause the hoisted object to be obstructed, making it difficult for them to see the object clearly during the hoisting process. This can lead to risks such as the hoisted object colliding with or getting caught on other objects. Based on this, wireless bullet cameras are widely used in the hoisting field because of their ability to remotely transmit real-time images, thereby improving the reliability of hoisting operations.

[0004] However, the wireless receiver and wireless transmitter module of related technologies are usually designed as separate units. During installation, the wireless receiver and wireless transmitter module are installed separately, which increases the installation steps. At the same time, the waterproofing of the external wireless transmitter module is difficult to meet the special environmental requirements of engineering machinery. Utility Model Content

[0032] A wireless bullet camera is a device that converts optical image signals into electrical signals for recording. It mainly uses camera devices to convert light signals into electrical signals, then into digital video signals, which are amplified by a preamplifier circuit, processed and adjusted by various circuits, and then sent to recording media such as video recording for storage and playback.

[0033] In the field of hoisting, hoisting workers are often affected by factors such as height and environment, which can cause the hoisted object to be obstructed, making it difficult for them to see the object clearly during the hoisting process. This can lead to risks such as the hoisted object colliding with or getting caught on other objects. Based on this, wireless bullet cameras are widely used in the hoisting field because of their ability to remotely transmit real-time images, thereby improving the reliability of hoisting operations.

[0034] However, the wireless receiver and wireless transmitter module of related technologies are usually designed as separate units. During installation, the wireless receiver and wireless transmitter module are installed separately, which increases the installation steps. At the same time, the waterproofing of the external wireless transmitter module is difficult to meet the special environmental requirements of engineering machinery.

[0035] Please refer to the following: Figures 1 to 5 This application provides a wireless receiver 100, which includes a mounting base 10 and a receiver body 20. The mounting base 10 is used to connect to a hoisting device. The receiver body 20 is connected to the mounting base 10 and includes a housing 21, an image acquisition module 22, and a signal transmission module 23. The housing 21 includes a sealed receiving space 101. The signal transmission module 23 is disposed in the receiving space 101 and is communicatively connected to the image acquisition module 22. The signal transmission module 23 is used for wireless communication with a signal receiving module.

[0036] The wireless bullet camera 100 is a camera terminal device, typically installed in a fixed location for filming or monitoring that location. In these embodiments of the application, the wireless bullet camera 100 is described only as an example of its application in hoisting equipment.

[0037] In these embodiments of the present application, the wireless camera 100 can be applied to lifting equipment such as crawler cranes and cranes to capture images of blind spots in the lifting equipment and transmit the captured image signals to the signal receiving module via wireless communication. In this case, by setting the signal receiving module in the operating room of the lifting equipment, the lifting operator can be aware of the surroundings of the object being lifted, thereby reducing the risk of the object colliding with other objects on site or getting caught on other objects during the lifting process.

[0038] Mounting base 10 is a component of the wireless receiver 100 used for mounting and fixing to the lifting equipment. In these embodiments of this application, the wireless receiver 100 can be mounted on the end of the boom of the lifting equipment via mounting base 10, thereby enabling monitoring of the lifted object from a top-down perspective.

[0039] In some embodiments, multiple wireless camera modules 100 can be simultaneously connected to the signal receiving module and the multiple wireless camera modules 100 can be installed at various parts of the boom of the hoisting equipment so that the hoisted object can be monitored from various angles when the hoisting equipment is working.

[0040] Mounting base 10 is used to connect to hoisting equipment. In possible implementations, mounting base 10 can be detachably connected to hoisting equipment by means of slot buckle connection or connector (screw, bolt) connection, so as to facilitate subsequent disassembly for maintenance or replacement. In some embodiments, mounting base 10 can also be fixedly connected to hoisting equipment by means of adhesive, welding or even integral molding, so as to improve the structural consistency between wireless gun 100 and hoisting equipment and reduce the risk of wireless gun 100 loosening or even falling.

[0041] The bolt body 20 is connected to the mounting base 10. In a possible implementation, the bolt body 20 and the mounting base 10 are movably connected so that after the bolt body 20 is connected to the mounting base 10, its shooting angle can be adjusted through the movable connection between the bolt body 20 and the mounting base 10. Alternatively, in some embodiments, the bolt body 20 and the mounting base 10 can be fixedly connected to improve the structural consistency between the bolt body 20 and the mounting base 10. In this case, the wireless bolt 100 can be used to shoot the suspended object from a specific angle.

[0042] The outer casing 21 is an external structural component of the bolt carrier 20, used to define the shape of the bolt carrier 20. At the same time, the outer casing 21 includes a sealed receiving space 101, which can be used to house the image acquisition module 22 and the signal transmission module 23, providing an independent and sealed working environment for the image acquisition module 22 and the signal transmission module 23, reducing the interference of the external environment on the two, and improving reliability.

[0043] It is understood that in the embodiment where the image acquisition module 22 is housed in the housing space 101, one end wall of the outer shell 21 needs to be made transparent so that the image acquisition module 22 can acquire image signals of the external environment through the transparent end wall.

[0044] The image acquisition module 22 is used to acquire real-time image signals of the hoisted object, and then converts the acquired image signals into electrical signals and transmits them to the signal transmission module 23.

[0045] The signal transmitting module 23 is used to connect with the signal receiving module to transmit the electrical signal transmitted by the image acquisition module 22 to the signal receiving module via wireless communication, so that the signal receiving module can obtain the image signal acquired by the image acquisition module 22 and display it in real time, so that the hoisting personnel can obtain the positional relationship between the hoisted object and the surrounding environment in real time.

[0046] In these embodiments of the present application, the wireless communication connection between the signal transmitting module 23 and the signal receiving module can be Bluetooth, WIFI or mobile communication.

[0047] The signal transmitting module 23 can be connected to the image acquisition module 22 via wired or wireless communication, depending on the actual situation of the product.

[0048] The signal transmitting module 23 is disposed within the receiving space 101. One possible configuration is that the signal transmitting module 23 is within the receiving space 101 and abuts against the inner wall of the outer casing 21, with the inner wall of the outer casing 21 restricting the degree of freedom of movement of the signal transmitting module 23 in all directions. Alternatively, in some embodiments, the signal transmitting module 23 can be detachably connected to the inner wall of the outer casing 21 via slots, blocks, connectors, or other means to facilitate subsequent maintenance or replacement of the signal transmitting module 23. Alternatively, in some embodiments, the signal transmitting module 23 can be fixedly connected to the inner wall of the outer casing 21 via bonding, welding, or other means to improve the structural stability of the signal transmitting module 23 and increase the overall structural reliability of the wireless receiver 100.

[0049] According to the wireless receiver 100 provided in this application embodiment, by placing the signal transmitting module 23 in the accommodating space 101 and communicating with the image acquisition module 22, the accommodating space 101 sealed by the outer shell 21 can isolate the signal transmitting module 23 from the outside world. Thus, the outer shell 21 can provide a stable working environment for the signal transmitting module 23, reducing the corrosion of the signal transmitting module 23 by external light or moisture. At the same time, this arrangement can improve the structural consistency between the signal transmitting module 23 and the outer shell 21, so that during the deployment of the wireless receiver 100, there is no need to install the signal transmitting module 23 separately, thereby improving the deployment efficiency of the wireless receiver 100.

[0050] In some embodiments, the bolt carrier 20 further includes an antenna 26, which is electrically connected to the signal transmitting module 23 and is at least partially disposed outside the receiving space 101.

[0051] Antenna 26 is electrically connected to signal transmitting module 23 so that the signal arm of signal transmitting module 23 can be extended outside housing 21 by antenna 26. In this way, the electromagnetic shielding of signal transmission by other electronic components inside housing 21 can be reduced, the possibility of signal weakening due to electromagnetic shielding of signal transmitted module 23 is reduced, and the stability of communication between signal transmitting module 23 and signal receiving module is improved.

[0052] At least a portion of the antenna 26 is disposed outside the receiving space 101. This means that the end of the antenna 26 used for electrical connection with the signal transmitting module 23 can pass through the housing 21 and enter the receiving space 101 to achieve electrical connection with the signal transmitting module 23. In some embodiments, the end of the antenna 26 used for electrical connection with the signal transmitting module 23 can also be disposed outside the housing 21, while the portion of the signal transmitting module 23 connected to the antenna 26 extends through the housing 21 to the outside of the receiving space 101 via a wire to achieve electrical connection with the antenna 26.

[0053] In these embodiments of this application, the antenna 26 can be movably connected to the housing 21, or the antenna 26 can include a first portion 261 fixedly connected to the housing 21 and a second portion 262 movably connected to the first portion 261. In this way, regardless of which method is adopted, the end of the antenna 26 facing away from the signal transmitting module 23 can be angled relative to the housing 21, thereby adjusting the signal transmission angle and further improving the stability of the communication connection between the signal transmitting module 23 and the signal receiving module.

[0054] In some embodiments, the housing 21 is provided with a through hole 211, the antenna 26 is disposed outside the receiving space 101, and one end of the antenna 26 passes through the through hole 211 and is connected to the signal transmitting module 23; the antenna 26 is interference-fitted with the hole wall of the through hole 211.

[0055] The outer casing 21 is provided with a through hole 211, wherein the through hole 211 can penetrate the wall structure along the thickness direction of a certain wall structure of the outer casing 21 to connect the internal accommodating space 101 of the outer casing 21 with the outside.

[0056] Antenna 26 is disposed outside the accommodating space 101, and one end of antenna 26 passes through through hole 211 and is connected to signal transmitting module 23. This means that the main body of antenna 26 is disposed outside the accommodating space 101 to realize signal transmission and reduce electromagnetic interference from other electronic components inside the housing 21 to signal transmission. At the same time, the end of antenna 26 used for electrical connection with signal transmitting module 23 passes through through hole 211 and is electrically connected to signal transmitting module 23.

[0057] The interference fit between the antenna 26 and the wall of the through hole 211 refers to the interference fit between the portion of the antenna 26 extending into the receiving space 101 and the wall of the through hole 211, thus achieving a seal of the outer casing 21 at the through hole 211. In these embodiments of this application, the antenna 26 includes a first portion 261 and a second portion 262, wherein the first portion 261 is the part of the antenna 26 used for electrical connection with the signal transmitting module 23. In this case, the first portion 261 is in the shape of a straight circular strip, and the diameter of the first portion 261 is larger than the diameter of the through hole 211. The end of the first portion 261 facing away from the signal transmitting module 23 is rotatably connected to the second portion 262, so that the second portion 262 can adjust the angle of signal transmission relative to the outer casing 21, thereby achieving a better communication connection with the signal receiving module.

[0058] In some embodiments of this application, the outer structure of the first part 261 may be made of a material that can undergo elastic deformation, so that the outer wall of the first part 261 can undergo elastic deformation by compression during installation, thereby achieving an interference fit with the wall of the through hole 211.

[0059] In some embodiments, a waterproof sealant (not shown) is provided at the interference fit between the antenna 26 and the through hole 211.

[0060] By providing a waterproof sealant at the interference fit between the antenna 26 and the through hole 211, the sealing performance of the housing 21 at the through hole 211 is further improved. For example, the waterproof sealant can be, but is not limited to, made of silicone sealant, acrylic sealant, polyurethane sealant or butyl rubber sealant.

[0061] In some embodiments, the number of antennas 26 is two, and the two antennas 26 are respectively disposed on opposite sidewalls of the housing 21.

[0062] Two antennas 26 are respectively installed on opposite side walls of the housing 21 to further improve the angular range of the antenna 26 transmitting signals, thereby further reducing the dead angle between the signal transmitting module 23 and the signal receiving module, so that the wireless gun 100 can establish good communication with the signal receiving module in any working state of the hoisting equipment.

[0063] In these embodiments of the present application, the housing 21 may include an end wall 212, a bottom wall 213 disposed opposite to the end wall 212, and a plurality of side walls 214 connecting the end wall 212 and the bottom wall 213. At least a portion of the end wall 212 is made of transparent material so that the image acquisition module 22 can acquire image light signals of the hoisting site through the end wall 212. The bottom wall 213 is used to connect with the mounting base 10. Through holes 211 are formed on any two opposite side walls 214 so that the antenna 26 can be connected to any two opposite side walls 214 of the housing 21.

[0064] In some embodiments, the signal transmitting module 23 includes a drive unit (not shown), and the bolt body 20 also includes a drive member 24; the drive member 24 cooperates with the drive unit, and at least a portion of the drive member 24 is disposed outside the receiving space 101; the drive member 24 is configured to drive the drive unit, which drives the signal transmitting module 23 to pair with the signal receiving module.

[0065] The drive unit is used to drive the signal transmitting module 23 to pair with the signal receiving module. A possible implementation is that the signal transmitting module 23 and the signal receiving module communicate wirelessly via Bluetooth. In this way, after the wireless gun 100 is installed on any hoisting equipment, the signal transmitting module 23 can be paired with the wireless receiving module of the hoisting equipment.

[0066] The driving component 24 is a physical component that can be operated by the staff. In some embodiments of this application, the driving component 24 can be set as a physical button, so that the staff can make the driving unit work by pressing the physical button, thereby driving the signal transmitting module 23 to communicate and pair with the signal receiving module.

[0067] In some embodiments, the driver 24 can be configured as a capacitive sensing button to further reduce the number of openings in the housing 21, thereby reducing the possibility of the housing 101 communicating with the outside world and further improving the sealing of the wireless receiver 100.

[0068] In some embodiments, the mounting base 10 is connected to the bolt carrier 20 via a rotation damper 11.

[0069] The mounting base 10 and the bolt carrier 20 are connected by a rotary damper 11, which allows the angle between the bolt carrier 20 and the mounting base 10 to be automatically adjusted. Furthermore, the bolt carrier 20 is always under the influence of gravity, ensuring that the image acquisition module 22 faces downwards for shooting. Thus, the wireless bolt carrier 100 provided in this embodiment is typically installed at the end of the boom of a hoisting device, enabling it to maintain a vertically downward orientation for shooting the hoisted object.

[0070] In these embodiments of this application, after the wireless camera 100 is installed, the camera body 20 can automatically adjust the shooting angle downward under the action of gravity. As the hoisting equipment operates, the angle of the boom changes, and the camera body 20 can also automatically adjust the shooting angle under the action of gravity so that the image acquisition module 22 is always aligned with the hoisted object.

[0071] In some embodiments, the image acquisition module 22 includes a camera 221 and at least one fill light 222, wherein the illumination direction of each fill light 222 is parallel to the optical axis of the camera 221.

[0072] In these embodiments of the present application, the camera 221 may be, but is not limited to, a fixed-focus lens, a zoom lens, and a motorized zoom lens.

[0073] The function of the supplementary light 222 is to provide illumination, enabling the wireless camera 100 to operate in nighttime environments. In these embodiments of this application, the number of supplementary lights 222 can be designed according to the type of hoisting equipment and the conventional distance between the hoisted object and the camera 221. Exemplarily, the number of supplementary lights 222 can be one, two, three, or four.

[0074] In these embodiments of the present application, multiple fill lights 222 can be evenly arranged around the periphery of the optical axis of the camera 221 to illuminate the suspended object and improve the quality of the image light signal acquired by the camera 221.

[0075] The illumination direction of each supplementary light 222 is parallel to the optical axis of the camera 221, so that the illumination direction of the supplementary light 222 is parallel to the shooting direction of the camera 221, and the light from the supplementary light 222 can better illuminate the hoisted object.

[0076] In some embodiments, the bolt carrier 20 also includes a battery (not shown) disposed in the receiving space 101, which is electrically connected to the image acquisition module 22 and the signal transmission module 23 respectively.

[0077] The function of the storage battery is to provide electrical energy. In these embodiments of the present application, the storage battery may be electrically connected to the image acquisition module 22 and the signal transmission module 23, respectively, to provide electrical energy to the image acquisition module 22 and the signal transmission module 23.

[0078] In these embodiments of the present application, the battery can be a primary battery for replacement after the power is depleted, or in some embodiments, the battery can be a secondary battery.

[0079] This application also provides a hoisting operation visualization system, which includes a wireless receiver 100, a signal receiving module, and a display device as described in any of the foregoing embodiments; the wireless receiver 100 is communicatively connected to the signal receiving module, and the signal receiving module is communicatively connected to the display device.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
