Description

Technical Field

[0001] This utility model relates to the field of lighting equipment, and in particular to a loader work light angle adjustment device. Background Technology

[0002] The development of loader work lights has gone through incandescent lamps, halogen lamps, HID lamps to the mainstream LED stage. LEDs have become the first choice due to their advantages such as high efficiency and energy saving, long life, high brightness, fast start-up and resistance to harsh environments. They meet the requirements of wide-angle, high brightness and uniform illumination, strong environmental adaptability and high safety and reliability, providing good lighting conditions for construction.

[0003] Although loader work lights can be used in various scenarios, they cannot adjust the illumination area, which makes it impossible to achieve high-precision, high-reliability, and multi-angle adjustable light sources. This makes it difficult to meet the growing application demands and increasingly stringent safety standards. Therefore, those skilled in the art have provided a loader work light angle adjustment device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a loader work light angle adjustment device that facilitates multi-angle adjustment of the work light and improves lighting accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a loader work light angle adjustment device, comprising a fixed base, a rotary motor provided on the upper end face of the fixed base, a frustum fixedly connected to the upper end face of the rotary motor, protrusions provided on both sides of the upper end face of the frustum, connecting arms provided on the two sides of the two protrusions that are far apart from each other, a dual-axis motor provided between the two protrusions, the two output ends of the dual-axis motor respectively passing through the two protrusions and extending to the side of the two connecting arms that are close to each other, a second rotating shaft provided at the upper end of the side of the two connecting arms that are close to each other, a support plate fixedly connected between the two second rotating shafts, a lighting lamp provided on the upper end face of the support plate, and a warning device provided above the rotary motor; With the above technical solution, when in use, the fixed base provides support and installation foundation for the entire device. When a horizontal adjustment device is required, a rotary motor is provided on the upper end of the fixed base. After the rotary motor is started, its output shaft drives the truncated cone that is fixedly connected to it to rotate. Since the truncated cone is equipped with a boss, connecting arm, support plate and lighting lamp, the rotation of the truncated cone will cause the entire upper structure to move in a circle around the axis of the rotary motor, thereby realizing the angle adjustment of the lighting lamp in the horizontal direction and expanding the horizontal range of the lighting. When a vertical adjustment device is needed, the dual-axis motor between the two bosses enables vertical angle adjustment. When the dual-axis motor is started, its two output ends pass through the bosses and connect to the connecting arms, driving the connecting arms to rotate around the output ends of the dual-axis motor. The upper ends of the connecting arms, which are close to each other on one side, are fixedly connected to the support plate through a second rotating shaft. The rotation of the connecting arms will cause the support plate to swing through the second rotating shaft. Since the lighting lamp is installed on the upper surface of the support plate, the swing of the support plate realizes the vertical angle adjustment of the lighting lamp, allowing the lighting lamp to swing up and down in the vertical plane to meet the lighting needs of different heights and angles.

[0006] Furthermore, the warning device includes a working warning light, the lower end face of which is fixedly connected to the outer side of the upper end face of the rotary motor, and a first warning light and a second warning light are respectively provided on the side of the two connecting arms that are far apart from each other. Through the above technical solution, the warning device is used to remind people around when the device is working. The lower end of the working warning light is fixedly connected to the outer side of the upper end of the rotary motor. When the device is started, the working warning light is lit, indicating that the device is running. The two connecting arms are respectively provided with a first warning light and a second warning light on their opposite sides. When the device is adjusted horizontally or vertically, the first warning light and the second warning light will also emit warning signals to remind people around to pay attention to safety from different directions.

[0007] Furthermore, a damping rod is rotatably connected to the middle of the outer wall of the dual-axis motor, and the output end of the damping rod is fixedly connected to the lower end face of the support plate; Through the above technical solution, the damping rod rotatably connected in the middle of the outer wall of the dual-axis motor has its output end fixedly connected to the lower end face of the support plate. During the swinging process of the support plate, the damping rod can play a buffering and stabilizing role, avoiding the support plate from violent shaking due to the rapid rotation of the dual-axis motor, and ensuring the stability of the vertical angle adjustment of the lighting lamp.

[0008] Furthermore, the lower inner wall of the fixed base is provided with a strong magnet, and the upper end face of the fixed base has five second screw holes symmetrically arranged in a circular manner leading to the lower end face of the fixed base. The rear end face of the fixed base is fixedly connected to a hanging rod, and the rear end face of the hanging rod and the center of both sides are provided with first screw holes. Through the above technical solution, a strong magnet is provided on the inner wall of the fixed base, which can be magnetically attracted to the metal parts of the loader to achieve fixation. Bolts are used to pass through the second screw hole to further fix the fixed base to the loader. In addition, the hanging rod on the rear end face of the fixed base and the first screw hole thereon can be used for additional fixing or suspension installation methods, which increases the flexibility and stability of the device installation.

[0009] Furthermore, a light-concentrating cover is provided on the outer side of the upper end surface of the support plate, and a fixing protrusion is provided at each of the four opposite corners inside the light-concentrating cover; With the above technical solution, when focused lighting is required, a focusing cover is provided on the outer side of the upper end of the support plate. The four diagonal corners of the focusing cover are provided with fixing protrusions. The fixing protrusions are fixedly connected to the support plate with screws, so that the focusing cover can concentrate the light emitted by the lighting lamp, making the light more concentrated and improving the brightness and effect of the lighting. When not in use, the focusing cover can be removed by unscrewing the screws on the fixing protrusions, thereby better meeting the different lighting needs of the loader during operation.

[0010] Furthermore, a circular rubber pad is provided on the outer side of the lower end face of the fixed base. The circular rubber pad has a through hole corresponding to five second screw holes. The lower end face of the strong magnet is flush with the lower end face of the circular rubber pad. With the above technical solution, a circular rubber pad is provided on the outer side of the lower end face of the fixed base. It can not only play the role of buffering and shock absorption, but also prevent the fixed base from directly contacting the surface of the loader and causing damage. The circular rubber pad has through holes and five second screw holes respectively, which facilitates the screws to pass through the circular rubber pad. The strong magnet is flush with the lower end face of the circular rubber pad, which facilitates the strong magnet to be magnetically attracted to the loader.

[0011] This utility model has the following beneficial effects: 1. In this utility model, the vertical and horizontal adjustment of the work lamp is achieved by driving a dual-axis motor and a rotary motor, realizing a high-precision, high-reliability, multi-angle adjustable light source, expanding the horizontal range of illumination and the lighting needs of different heights and angles, and meeting the growing application needs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1-5 An embodiment of this utility model provides a loader work light angle adjustment device, including a fixed base 1, a rotary motor 2 on the upper end surface of the fixed base 1, a frustum 12 fixedly connected to the upper end surface of the rotary motor 2, a boss 10 on both sides of the upper end surface of the frustum 12, a connecting arm 16 on the two sides of the two bosses 10 that are far apart from each other, a dual-axis motor 11 between the two bosses 10, the two output ends of the dual-axis motor 11 respectively passing through the two bosses 10 and reaching the side of the two connecting arms 16 that are close to each other, a second rotating shaft 17 on the upper end of the side of the two connecting arms 16 that are close to each other, a support plate 3 fixedly connected between the two second rotating shafts 17, a lighting lamp 4 on the upper end surface of the support plate 3, and a warning device 8 above the rotary motor 2.

[0017] In use, the fixed base 1 provides support and installation foundation for the entire device. When a horizontal adjustment device is required, a rotary motor 2 is provided on the upper surface of the fixed base 1. After the rotary motor 2 is started, its output shaft drives the truncated cone 12 fixedly connected to it to rotate. Since the truncated cone 12 is equipped with components such as the boss 10, connecting arm 16, support plate 3 and lighting lamp 4, the rotation of the truncated cone 12 will cause the entire upper structure to move in a circle around the axis of the rotary motor 2, thereby realizing the angle adjustment of the lighting lamp 4 in the horizontal direction and expanding the horizontal range of the lighting.

[0018] When a vertical adjustment device is needed, the dual-axis motor 11 between the two bosses 10 can realize vertical angle adjustment. When the dual-axis motor 11 is started, its two output ends pass through the bosses 10 and are connected to the connecting arm 16, driving the connecting arm 16 to rotate around the output end of the dual-axis motor 11. The upper ends of the connecting arms 16 that are close to each other on one side are fixedly connected to the support plate 3 through the second rotating shaft 17. The rotation of the connecting arm 16 will drive the support plate 3 to swing through the second rotating shaft 17. Since the lighting lamp 4 is installed on the upper surface of the support plate 3, the swing of the support plate 3 realizes the angle adjustment of the lighting lamp 4 in the vertical direction, so that the lighting lamp 4 can swing up and down in the vertical plane to meet the lighting needs of different heights and angles.

[0019] like Figure 2 and 5 As shown, the warning device 8 includes a working warning light 803. The lower end face of the working warning light 803 is fixedly connected to the outer side of the upper end face of the rotary motor 2. The two connecting arms 16 are respectively provided with a first warning light 801 and a second warning light 802 on their opposite sides.

[0020] The warning device 8 is used to alert people around the device when it is working. The lower end of the working warning light 803 is fixedly connected to the outer side of the upper end of the rotary motor 2. When the device is started, the working warning light 803 lights up, indicating that the device is running. The two connecting arms 16 are respectively provided with a first warning light 801 and a second warning light 802 on their opposite sides. When the device is adjusted horizontally or vertically, the first warning light 801 and the second warning light 802 will also emit warning signals to remind people around the device to pay attention to safety from different directions.

[0021] like Figure 1 , 2 As shown in Figures 3 and 4, a damping rod 9 is rotatably connected to the middle of the outer wall of the dual-axis motor 11, and the output end of the damping rod 9 is fixedly connected to the lower end face of the support plate 3.

[0022] The damping rod 9, which is rotatably connected to the middle of the outer wall of the dual-axis motor 11, has its output end fixedly connected to the lower end face of the support plate 3. During the swinging process of the support plate 3, the damping rod 9 can play a role in buffering and stabilizing, preventing the support plate 3 from shaking violently due to the rapid rotation of the dual-axis motor 11, and ensuring the stability of the vertical angle adjustment of the lighting lamp 4.

[0023] A strong magnet 13 is provided on the lower inner wall of the fixed base 1. Five second screw holes 14 are symmetrically arranged on the upper end face of the fixed base 1, leading to the lower end face of the fixed base 1. A hanging rod 6 is fixedly connected to the rear end face of the fixed base 1. A first screw hole 7 is provided at the center of the rear end face and the two sides of the hanging rod 6.

[0024] A strong magnet 13 is provided on the lower inner wall of the fixed base 1, which can be magnetically attracted to the metal parts of the loader for fixation. The fixed base 1 is further fixed to the loader by using bolts through the second screw hole 14. In addition, the hanging rod 6 on the rear end face of the fixed base 1 and the first screw hole 7 thereon can be used for additional fixing or suspension installation methods, which increases the flexibility and stability of the device installation.

[0025] A light-concentrating cover 5 is provided on the outer side of the upper end of the support plate 3, and a fixing protrusion 15 is provided at each of the four opposite corners inside the light-concentrating cover 5.

[0026] When focused lighting is required, a focusing cover 5 is provided on the outer side of the upper end of the support plate 3. The focusing cover 5 has four fixed protrusions 15 at the four opposite corners inside. The fixed protrusions 15 are fixedly connected to the support plate 3 with screws, so that the focusing cover 5 can concentrate the light emitted by the lighting lamp 4, making the light more concentrated and improving the brightness and effect of the lighting. When not in use, the focusing cover 5 can be removed by unscrewing the screws on the fixed protrusions 15, so as to better meet the different lighting needs of the loader during operation.

[0027] A circular rubber pad 18 is provided on the outer side of the lower end face of the fixed base 1. The circular rubber pad 18 has a through hole and five second screw holes 14 respectively. The lower end face of the strong magnet 13 is flush with the lower end face of the circular rubber pad 18.

[0028] A circular rubber pad 18 is provided on the outer side of the lower end face of the fixed base 1. It not only plays a role in buffering and shock absorption, but also prevents the fixed base 1 from directly contacting the surface of the loader and causing damage. The circular rubber pad 18 has through holes and five second screw holes 14 respectively, which facilitates the screws to pass through the circular rubber pad 18. The strong magnet 13 is flush with the lower end face of the circular rubber pad 18, which facilitates the strong magnet 13 to be tightly magnetically attracted to the loader.

[0029] Working principle: During use, the fixed base 1 provides support and installation foundation for the entire device. The lower inner wall of the fixed base 1 is equipped with a strong magnet 13, which can be magnetically attracted to the metal parts of the loader to achieve initial fixation. At the same time, the lower end face of the fixed base 1 is equipped with a circular rubber pad 18 on the outer side. It not only plays a role in buffering and shock absorption, but also prevents the fixed base 1 from directly contacting the surface of the loader and causing damage. The circular rubber pad 18 has through holes and five second screw holes 14 respectively, which facilitates the use of bolts to pass through the second screw holes 14 to further fix the fixed base 1 to the loader. In addition, the hanging rod 6 on the rear end face of the fixed base 1 and its first screw hole 7 can be used for additional fixing or suspension installation methods, which increases the flexibility and stability of the device installation.

[0030] When a horizontal adjustment device is needed, a rotary motor 2 is provided on the upper end face of the fixed base 1. After the rotary motor 2 is started, its output shaft drives the truncated cone 12 fixedly connected to it to rotate. Since the truncated cone 12 is equipped with components such as the boss 10, connecting arm 16, support plate 3 and lighting lamp 4, the rotation of the truncated cone 12 will cause the entire upper structure to move in a circle around the axis of the rotary motor 2, thereby realizing the angle adjustment of the lighting lamp 4 in the horizontal direction and expanding the horizontal range of the lighting.

[0031] When a vertical adjustment device is needed, the dual-axis motor 11 between the two bosses 10 can realize vertical angle adjustment. When the dual-axis motor 11 is started, its two output ends pass through the bosses 10 and are connected to the connecting arm 16, driving the connecting arm 16 to rotate around the output end of the dual-axis motor 11. The upper ends of the connecting arms 16 that are close to each other on one side are fixedly connected to the support plate 3 through the second rotating shaft 17. The rotation of the connecting arm 16 will drive the support plate 3 to swing through the second rotating shaft 17. Since the lighting lamp 4 is installed on the upper surface of the support plate 3, the swing of the support plate 3 realizes the angle adjustment of the lighting lamp 4 in the vertical direction, so that the lighting lamp 4 can swing up and down in the vertical plane to meet the lighting needs of different heights and angles.

[0032] The damping rod 9, which is rotatably connected to the middle of the outer wall of the dual-axis motor 11, has its output end fixedly connected to the lower end face of the support plate 3. During the swinging process of the support plate 3, the damping rod 9 can play a role in buffering and stabilizing, preventing the support plate 3 from shaking violently due to the rapid rotation of the dual-axis motor 11, and ensuring the stability of the vertical angle adjustment of the lighting lamp 4.

[0033] The warning device 8 is used to alert people around the device when it is working. The lower end of the working warning light 803 is fixedly connected to the outer side of the upper end of the rotary motor 2. When the device starts working, the working warning light 803 lights up, indicating that the device is running. The two connecting arms 16 are respectively provided with a first warning light 801 and a second warning light 802 on their opposite sides. When the device is adjusted horizontally or vertically, the first warning light 801 and the second warning light 802 will also emit warning signals to remind people around the device to pay attention to safety from different directions. Usually, a steering angle sensor is used to detect the rotation angle and direction of the steering wheel. The sensor transmits the signal to the electronic control unit (ECU). The ECU controls the first warning light 801 and the second warning light 802 to turn on and off according to the signal. This is a common technical means in existing control devices and will not be described in detail here.

[0034] When focused lighting is required, a focusing cover 5 is provided on the outer side of the upper end of the support plate 3. The focusing cover 5 has four fixed protrusions 15 at the four opposite corners inside. The fixed protrusions 15 are fixedly connected to the support plate 3 with screws, so that the focusing cover 5 can concentrate the light emitted by the lighting lamp 4, making the light more concentrated and improving the brightness and effect of the lighting. When not in use, the focusing cover 5 can be removed by unscrewing the screws on the fixed protrusions 15, so as to better meet the different lighting needs of the loader during operation.

[0035] The dual-axis motor 11 and the rotary motor 2 are driven by electromagnetic induction to generate rotational power. The power is transmitted to the output shaft through different transmission methods, and the motor is precisely controlled through specific control methods to meet the driving needs of various equipment. When the device is impacted, the damping rod 9 can slow down the transmission speed of the impact energy. Through its own deformation and energy dissipation process, the instantaneous impact force is dispersed over a longer period of time, reducing the impact on the device and protecting the device from damage. At the same time, it also helps to stabilize the state of the device. The above are common technical means in existing drive and buffer devices, which will not be elaborated on here.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
