Description

Technical Field

[0001] This invention relates to the field of remote controls, and in particular to a handheld dual-screen smart remote control. Background Technology

[0002] Currently, unmanned remote controls used in the construction machinery field generally suffer from bulky structures, which are not ergonomically designed for easy handling and operation, easily leading to operator hand fatigue. Furthermore, their waterproof rating and high-temperature resistance are severely inadequate, making them prone to failure in harsh conditions such as humidity and high temperatures. In addition, these devices cannot display images transmitted from the vehicle's vision system in real time and completely lack electromagnetic interference and anti-static functions, making them susceptible to interference from environmental electromagnetic signals and even damage from static electricity, significantly limiting the stable operation of construction machinery in complex environments. Summary of the Invention

The handheld dual-screen smart remote control includes an upper shell sealed structure, a lower sealed heat dissipation structure at the bottom, an image and data transmission display integrated structure at the top, and a disabling button structure on its periphery. It has an IP65 waterproof rating, is anti-interference and anti-static, and features a visible upper screen and a lower screen that displays real-time vehicle data. The handheld structure is compact and lightweight.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A handheld dual-screen smart remote control includes an upper shell sealed structure, a lower sealed heat dissipation structure at the bottom, an image and data transmission display integrated structure at the top, and a disabled button structure on its periphery. The upper shell sealing structure is the main structure of the remote control, and its inner seal integrates the remote control electrical components and accessories; The integrated structure of image transmission and data transmission display includes an image transmission display and a data transmission display, which are hinged together by a hinge opening and closing device. The lower sealed heat dissipation structure includes a thermally conductive sealed heat dissipation plate, a heat dissipation axial fan, an airflow guiding heat dissipation plate, and a lower housing; The airflow-guided heat sink is a square frame structure with an opening at the top. A through hole is provided in the middle of the bottom plate, and the cooling axial fan is installed in the through hole. Several strip-shaped heat dissipation fins are evenly arranged between the inner peripheral wall of the airflow guide heat dissipation plate and the outer peripheral wall of the heat dissipation axial fan. Each strip-shaped heat dissipation fin is arranged vertically along its length. The lower shell is a square frame structure with an opening at the top. An air duct is opened in the middle of the bottom plate, and the airflow guide heat dissipation plate is installed in the air duct. The thermally conductive and sealed heat sink is encapsulated at the top opening of the airflow-guided heat sink, and its four corners are bolted to the inner wall of the lower housing. The lower housing of the lower sealed heat dissipation structure is assembled and connected to the bottom of the upper sealed housing structure.

[0005] Furthermore, the outer shell of the upper sealing structure is made of ABS, and its interior is uniformly coated with a layer of conductive silver paint as a signal shielding layer.

[0006] Furthermore, the image transmission display is used in the video monitoring system to monitor the vehicle's surroundings and vehicle status in real time; the image transmission display is integrally formed at the top center of the upper housing sealing structure, and it is electrically connected to the integrated components within the upper housing sealing structure. The data transmission display is used to monitor the parameters of the vehicle's internal systems, and parameterized information about the vehicle's internal operation is visible. The data transmission display is electrically connected to the integrated components inside the sealed upper shell structure via a connecting cable.

[0007] Furthermore, the top two sides of the upper shell sealing structure are symmetrically integrated with waterproof three-axis rockers and silicone-sealed six buttons; the symmetrically arranged waterproof three-axis rockers are located on the upper part of both sides, and the symmetrically arranged silicone-sealed six buttons are located on the lower part of both sides; a waterproof emergency stop button is integrated at the lower part of the top center of the upper shell sealing structure 1.

[0008] Furthermore, the silicone-sealed six buttons are made of silicone anti-static material.

[0009] Furthermore, along the direction from the inner wall of the airflow guide heat sink to the outer wall of the axial flow fan, the strip-shaped heat sink fins gradually taper from the larger end to the smaller end, with an arc-shaped blade at the bottom and a straight line at the top.

[0010] Furthermore, the thermally conductive and sealed heat sink is made of brass alloy or aluminum; structural sealant is applied at the connection between the thermally conductive and sealed heat sink and the inner wall of the lower housing.

[0011] Furthermore, a cavity is provided around the periphery of the upper shell sealing structure, and the disabled button structure is assembled in the cavity; the disabled button structure includes a disabled button, a button plate and a disabled button sealing cover from the inside to the outside.

[0012] Furthermore, the disabled button is an anti-static silicone button coated with conductive oil to conduct the button board so that the button operation can be commanded; the disabled button is assembled in the cavity opened on the periphery of the upper shell sealing structure. The button panel has square ventilation areas, which are densely covered with honeycomb-shaped ventilation holes. There are two square ventilation areas. The honeycomb-shaped ventilation holes are used to prevent the disabled button from malfunctioning due to vacuum adsorption. The button panel is mounted on the outside of the disabled button.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

[0024] In the description of this invention, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this invention. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the scope of protection of this invention.

[0025] like Figure 1-2 As shown, a handheld dual-screen smart remote control includes an upper shell sealing structure 1, a lower sealing heat dissipation structure 2 at its bottom, an image transmission and data transmission display integrated structure 3 at its top, and a disabled button structure 4 on its periphery.

[0026] The upper shell sealing structure 1 is the main structure of the remote control. Its inner seal integrates the remote control electrical components and accessories, including a wireless LoRa module, an integrated WIFI module, a six-axis angle sensor, a Beidou GPS support module, a UWB ranging module, and a positioning module.

[0027] Furthermore, to address the anti-static requirements, the upper shell sealing structure 1 is made of ABS material, with a layer of conductive silver paint evenly sprayed inside as a signal shielding layer, effectively shielding the external signal layer and ensuring that the remote control is not subject to electromagnetic interference.

[0028] like Figure 1-3 As shown, the integrated structure of the image transmission and data transmission display is compact and lightweight, achieving a high degree of integration of image transmission and data transmission. Its core always revolves around the three goals of "clear vision, stable control, and long-distance transmission".

[0029] Furthermore, the integrated structure 3 for image transmission and data transmission display includes an image transmission display 31 and a data transmission display 32, which are hinged together by a hinge opening and closing device 33.

[0030] Among them, the image transmission display 31 is mainly used in video monitoring systems to monitor the vehicle's surroundings and vehicle status in real time. Its analog frequency band is mainly 5.8GHz, which has a short antenna and relatively less interference. It also has 1.2GHz and 2.4GHz, etc. Its digital frequency band 2.4GHz and 5.8GHz dual-band adaptive switching to avoid interference and obtain the best performance.

[0031] Among them, the data transmission display 32 is used to monitor the internal system parameters of the vehicle, and parameterized internal information of the vehicle operation can be seen. Its frequency band is 900MHz, 433MHz or 2.4GHz. It has strong diffraction capability in the low frequency band and is suitable for long distance and complex environment.

[0032] Furthermore, the hinge opening and closing device is used to connect the image transmission display and the data transmission display, and the hidden cable passage structure effectively protects the image transmission display connection cable. In addition, since the hinge opening and closing device is made of metal, the wire harness passes through the inside of the metal hinge, which is equivalent to a metal shielding layer, thus having strong anti-electromagnetic interference performance.

[0033] Furthermore, the data transmission display 32 is integrally formed at the top center of the upper shell sealing structure 1, and is electrically connected to the integrated component inside the upper shell sealing structure 1; the image transmission display 31 is electrically connected to the integrated component inside the upper shell sealing structure 1 via a connecting cable.

[0034] Furthermore, such as Figure 3 As shown, waterproof three-axis rockers 11 and silicone-sealed six buttons 12 are symmetrically integrated on both sides of the top of the upper shell sealing structure 1; the symmetrically arranged waterproof three-axis rockers 11 are located on the upper part of both sides, and the symmetrically arranged silicone-sealed six buttons 12 are located on the lower part of both sides; a waterproof emergency stop button 13 is integrated at the lower part of the top center of the upper shell sealing structure 1; the silicone-sealed six buttons, waterproof three-axis rockers, and waterproof emergency stop button are used to ensure good sealing of the upper shell, with a waterproof rating of IP65.

[0035] Furthermore, the silicone-sealed six-button 12 uses silicone anti-static buttons, which are comfortable to operate. The silkscreened icons clearly indicate the functional requirements, and the use of anti-static materials effectively reduces the damage of static electricity to electrical components.

[0036] The lower sealed heat dissipation structure 2 not only seals the entire machine but also dissipates heat in real time.

[0037] like Figure 1-2 As shown, the lower sealed heat dissipation structure 2 includes a heat-conducting sealed heat dissipation plate 21, a heat dissipation axial flow fan 22, an airflow guiding heat dissipation plate 23, and a lower housing 24.

[0038] The airflow-guided heat dissipation plate 23 is a square frame structure with an open top. A through hole is provided in the middle of its bottom plate for mounting the heat dissipation axial fan 22. The heat dissipation axial fan 22 is mounted in the through hole. like Figure 4 As shown, several strip-shaped heat dissipation fins 25 are evenly arranged between the inner peripheral wall of the airflow guiding heat dissipation plate 23 and the outer peripheral wall of the cooling axial fan 22. Each strip-shaped heat dissipation fin is arranged vertically along its length, such as... Figure 4 As shown, several strip-shaped heat dissipation fins radiate outwards within the space formed by the inner peripheral wall of the airflow guiding heat dissipation plate 23 and the outer peripheral wall of the heat dissipation axial flow fan 22.

[0039] Furthermore, along the direction from the inner peripheral wall of the airflow guide heat sink 23 to the outer peripheral wall of the axial cooling fan 22, the strip-shaped heat sink fins gradually taper from the larger end to the smaller end, with an arc-shaped blade at the bottom and a straight line at the top, as shown. Figure 4 As shown, the arrangement is such that the smaller end is close to the outer peripheral wall of the axial fan 22, and the larger end is close to the inner peripheral wall of the airflow guide heat sink 23.

[0040] The airflow-guided heat dissipation plate features a centralized distributed strip heat dissipation fin structure that simulates the flow of hot air, effectively guiding the flow of hot air and dissipating heat from all four sides. This results in high heat dissipation efficiency and effectively improves the stable operation of the system.

[0041] Furthermore, the lower housing 24 is a square frame structure with an opening at the top, and an air duct opening is provided in the middle of its bottom plate for mounting the airflow guiding heat dissipation plate 23; as Figure 2 As shown, the airflow guide heat dissipation plate 23 is assembled inside the air duct opening; Furthermore, the thermally conductive and sealed heat sink 21 is encapsulated at the top opening of the airflow guiding heat sink 23, and its four corners are connected to the inner wall of the lower housing 24 by bolts. Furthermore, since the thermally conductive and sealed heat sink 21 is directly connected to the lower housing 24, structural sealant is applied to the connection between the thermally conductive and sealed heat sink 21 and the inner wall of the lower housing 24 to isolate the internal and external communication, thus achieving an IP65 waterproof rating.

[0042] Furthermore, the heat-conducting and sealing heat sink 21 is made of brass alloy, which has good thermal conductivity and effectively protects the heat dissipation of components and ensures that video and data transmission are not interrupted during the operation of the remote control.

[0043] Optionally, the thermally conductive sealing heat sink 21 can also be made of aluminum or other metal thermally conductive materials.

[0044] Furthermore, such as Figure 7 As shown, an air intake waterproof duct 27 is arranged at the center of the air duct opening. The air intake waterproof duct includes an inner ring. The inner and outer ring air-intake waterproof zones are divided into an inner ring air-intake waterproof zone and an outer ring air-intake waterproof zone. The inner ring air-intake waterproof zone is densely covered with multiple small air-intake holes, while the outer ring air-intake waterproof zone is densely covered with multiple fan-shaped air-intake holes. The size of the fan-shaped air-intake holes is larger than that of the small air-intake holes.

[0045] Furthermore, an annular exhaust waterproof channel 26 is arranged on the outer periphery of the air duct opening, and multiple elongated exhaust holes are evenly arranged in the annular exhaust waterproof channel.

[0046] The lower sealed heat dissipation structure effectively seals the entire unit. When the remote control and the entire unit are running, the lower sealed heat dissipation structure activates synchronously. During operation, the system simultaneously dissipates and cools the entire unit. Specifically, natural air enters through the annular exhaust waterproof channel, cooling the entire unit and turning it into hot air. A small portion of the hot air is forced out through the annular exhaust waterproof channel, while the remaining hot air inside the unit transfers heat to the heat dissipation fins through the thermally conductive sealed heat dissipation plate. Furthermore, since the area of ​​the intake waterproof air duct matches the area of ​​the airflow guiding heat dissipation plate, the cooling axial fan continuously draws in external natural air, efficiently cooling the thermally conductive sealed heat dissipation plate and heat dissipation fins. In other words, the thermally conductive sealed heat dissipation plate and heat dissipation fins continuously remove heat from the entire unit through the cooling axial fan, thereby achieving overall cooling of the entire unit.

[0047] The present invention provides an assembly method for a lower sealed heat dissipation structure 2, comprising the following steps: The axial fan 22 is mounted at the through hole of the airflow guide heat sink 23; After the axial fan 22 and the airflow guide heat sink 23 are assembled, the airflow guide heat sink 23 is installed at the air duct opening of the lower housing 24. A thermally conductive and sealed heat sink 21 is encapsulated at the top opening of the airflow guiding heat sink 23 and installed on the inner wall of the lower housing 24 by bolts. Structural sealant is applied to the connection between the thermally conductive and sealed heat sink 21 and the inner wall of the lower housing 24. Thus, the thermally conductive and sealed heat sink 21 can not only achieve the overall encapsulation of the cooling axial fan 22 and the airflow guiding heat sink 23, but also effectively isolate the entire structure from the outside world.

[0048] The top of the lower housing of the lower sealing heat dissipation structure 2 is assembled and connected to the bottom of the housing of the upper housing sealing structure 1. For example... Figure 1 As shown, the lower shell size of the lower sealing heat dissipation structure 2 matches the shell size of the upper shell sealing structure 1.

[0049] The disabling button structure 4 is designed to prevent vehicle loss of control due to misoperation. Only by pressing the disabling button structure can the issued command be executed, ensuring a high level of safety. The upper housing sealing structure 1 has a cavity on its circumference, within which the disabling button structure 4 is assembled.

[0050] The disabled button structure 4 includes, from the inside out, a disabled button 41, a button plate 42, and a disabled button sealing cover 43; The disabled button 41 is an anti-static silicone button coated with conductive oil to conduct the button plate so that the button operation can be commanded; the disabled button 41 is assembled in the cavity opened on the circumference of the upper shell sealing structure. like Figure 5 As shown, the button plate 42 is provided with a square ventilation area 44, which is densely covered with honeycomb ventilation holes 45. There are two square ventilation areas. The honeycomb ventilation holes can effectively prevent the disabled button from malfunctioning due to vacuum adsorption. The button plate 42 is mounted on the outside of the disabled button 41. The disabled button sealing cover 43 is assembled on the outside of the button plate 42. The disabled button sealing cover is used to seal and encapsulate the button plate and the disabled button, and the sealing level can reach the IP65 waterproof level.

[0051] A handheld dual-screen smart remote control, such as Figure 6 As shown, it also includes a four-point hanging ring distribution structure 5, which includes four hanging rings.

[0052] Preferably, four hanging rings are arranged at the four corners of the data transmission display 32. The four-point hanging ring distribution structure is used for hanging straps or back straps to prevent the remote control from falling off, which could cause damage to the appearance or components of the remote control.

[0053] 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.
