Description

Technical Field

[0001] This utility model relates to the field of material handling equipment, and in particular to a load-bearing platform vehicle. Background Technology

[0002] Platform vehicles with handling functions are a commonly used type of handling equipment. Patent publication CN116237912A discloses a platform vehicle with handling functions. This platform vehicle moves by installing four wheels on the frame and rotating the four wheels. However, this type of platform vehicle has a problem: when traversing obstacles, if a heavy object on the platform is unstable, it is easy for it to slip backward. When a heavy object slips backward due to instability, the two front wheels are easily suspended in the air, causing the vehicle to become suspended and stuck, resulting in poor reliability. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a load-bearing platform vehicle that utilizes a triangular frame with two wheels as wheels, reducing the probability of heavy objects slipping backward due to instability when climbing slopes, and reducing the probability of the entire platform vehicle becoming suspended and stuck due to some wheels being suspended in the air.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A load-bearing platform vehicle includes a frame and several triangular frames. A robotic arm is mounted on the frame. Each triangular frame has two wheels and a motor. The motor is coupled with one of the wheels. Each triangular frame is independently mounted on the frame via a mounting shaft. The wheels and robotic arms are located on opposite sides of the frame. There are at least four triangular frames.

[0006] In this type of heavy-duty platform vehicle, triangular frames are installed on the frame, and the triangular frames can rotate relative to the frame. Each triangular frame is equipped with a wheel, and the wheel can rotate relative to the triangular frame. Since each triangular frame is equipped with a motor, the wheel that is connected to the motor is the powered wheel, and the wheel that is not connected to the motor is the unpowered wheel. The rotation of the powered wheel enables the movement of the entire frame.

[0007] In this type of load-bearing platform vehicle, wheels are mounted using triangular frames, with wheels installed on each triangular frame, thus giving the entire load-bearing platform vehicle relatively strong load-bearing capacity.

[0008] In this type of load-bearing platform vehicle, there are no fewer than four triangular supports, and each triangular support is equipped with one driven wheel and one undriven wheel. Therefore, this type of load-bearing platform has at least eight contact points with the ground. Compared with four-wheeled load-bearing platform vehicles, this type of load-bearing platform vehicle has more support points and better support stability. At the same time, in this type of load-bearing platform vehicle, since the triangular support with two wheels is used instead of the traditional one wheel, the swing and lifting range of the frame is relatively small when climbing. Therefore, the probability of the load on the frame slipping backward due to instability of the center of gravity is reduced. Since more wheels are in contact with the ground and each triangular support is self-powered, the probability of the entire vehicle becoming suspended and stuck due to some wheels being suspended in the air is reduced.

[0009] In summary, this type of load-bearing platform vehicle utilizes a triangular frame with two wheels as wheels, reducing the probability of heavy objects slipping backward due to instability of the center of gravity when climbing slopes, and reducing the probability of the entire platform vehicle becoming suspended and stuck due to some wheels being suspended in the air.

[0010] Optionally, the frame is provided with a sliding groove, and a limiting sliding post is slidably disposed in the sliding groove.

[0011] Specifically, the limiting slide is installed in the slide groove. The limiting slide can slide in the slide groove, and the function of the limiting slide is to limit the items on the frame.

[0012] Optionally, there are multiple slides, and the slides are parallel and do not contact each other. Each slide is provided with multiple limiting slides.

[0013] Multiple slides are installed, and each slide has multiple limit slides. This is to create multiple limit positions, thereby better limiting the weight on the frame.

[0014] Alternatively, a lead screw can be installed inside the frame, and then the bracket can be used to install the limiting slide pins on the lead screw. The movement of the lead screw can be used to slide the limiting slide pins, so that the distance between the limiting slide pins can be automatically adjusted as needed.

[0015] Optionally, a lifting platform may also be included, which is mounted on the vehicle frame.

[0016] The purpose of a lifting platform is to facilitate lifting operations.

[0017] Optionally, the lifting platform is provided with a support platform, the support platform is provided with a guide rail, and a support plate is slidably mounted on the guide rail.

[0018] The support plate can slide relative to the support platform. If an electric telescopic rod or a guide rail is installed between the support platform and the support plate, then the support plate can slide automatically relative to the support platform.

[0019] Optionally, it may also include a battery disposed within the vehicle frame.

[0020] The battery's function is to supply power to all electrical equipment. A control unit is also installed within the chassis, electrically connected to the battery. All electrical equipment on the platform vehicle is controlled by the control unit.

[0021] Optionally, a photovoltaic panel may also be included, which is rotatably mounted on the edge of the vehicle frame.

[0022] The photovoltaic panels can be installed on the edge of the frame via electric hinges, which can control the folding or unfolding of the photovoltaic panels on the frame.

[0023] Optionally, a camera may also be included, which is mounted on the robotic arm.

[0024] The camera's function is to capture images of the robotic arm during its operation.

[0025] The beneficial effects of this utility model are: by using a tripod with two wheels as wheels, the probability of heavy objects slipping backward due to instability of the center of gravity when climbing slopes is reduced, and the probability of the entire platform vehicle becoming suspended and stuck due to some wheels being suspended in the air is also reduced.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] As attached Figure 1 As shown, a load-bearing platform vehicle includes a frame 4 and several triangular frames 11. A robotic arm 1 is mounted on the frame 4. Each triangular frame 11 is equipped with two wheels 10 and a motor. The motor is engaged with one of the wheels 10. Each triangular frame 11 is independently mounted on the frame 4 via a mounting shaft 12. The wheels 10 and the robotic arm 1 are located on both sides of the frame 4. There are at least four triangular frames 11.

[0033] In this type of heavy-duty platform vehicle, a triangular frame 11 is installed on the frame 4. The triangular frame 11 can rotate relative to the frame 4, and each triangular frame 11 is equipped with a wheel 10, which can rotate relative to the triangular frame 11. Since each triangular frame 11 is equipped with a motor, the wheel 10 that is connected to the motor is the powered wheel, while the wheel 10 that is not connected to the motor is the unpowered wheel. The rotation of the powered wheel enables the movement of the entire frame 4.

[0034] In this type of load-bearing platform vehicle, wheels 10 are mounted on triangular frames 11, and each triangular frame 11 is equipped with a wheel 10, so the load-bearing capacity of the entire load-bearing platform vehicle is relatively strong.

[0035] In this type of load-bearing platform vehicle, there are no fewer than four triangular frames 11, and each triangular frame 11 is equipped with one driven wheel and one undriven wheel. Therefore, this type of load-bearing platform has at least eight contact points with the ground. Compared with a four-wheeled load-bearing platform vehicle, this type of load-bearing platform vehicle has more support points and better support stability. At the same time, in this type of load-bearing platform vehicle, since the triangular frames 11 with two wheels 10 are used instead of the traditional one wheel 10, the swing and lifting range of the frame 4 is relatively small when climbing. Therefore, the probability of the load on the frame 4 slipping backward due to instability of the center of gravity is reduced. Since more wheels 10 are in contact with the ground, and each triangular frame 11 is self-powered, the probability of the entire vehicle becoming suspended and stuck due to some wheels 10 being suspended is reduced.

[0036] In summary, this type of load-bearing platform vehicle utilizes a triangular frame 11 with two wheels 10 as wheels 10, which reduces the probability of heavy objects slipping backward due to instability of the center of gravity when climbing slopes, and reduces the probability of the entire platform vehicle becoming suspended and stuck due to some wheels 10 being suspended in the air.

[0037] As attached Figure 1 As shown, the frame 4 is provided with a slide groove 401, and a limit slide post 3 is slidably arranged in the slide groove 401.

[0038] Specifically, the limiting slide post 3 is installed in the slide groove 401. The limiting slide post 3 can slide in the slide groove 401. The function of the limiting slide post 3 is to limit the items on the frame 4.

[0039] As attached Figure 1 As shown, there are multiple slide grooves 401, and the slide grooves 401 are parallel and do not contact each other. Each slide groove 401 is provided with multiple limiting slide pins 3.

[0040] Multiple slide grooves 401 are provided, and multiple limit slide pins 3 are provided in each slide groove 401. This is to form multiple limit positions, so as to better limit the weight on the frame 4.

[0041] Alternatively, a lead screw can be installed inside the frame 4, and the bracket can be used to install the limiting slide 3 on the lead screw. The movement of the lead screw can be used to slide the limiting slide 3, so that the distance between the limiting slide 3 can be automatically adjusted as needed.

[0042] As attached Figure 1 As shown, it also includes a lifting platform 8, which is mounted on the frame 4.

[0043] The function of the lifting platform 8 is to facilitate lifting operations.

[0044] As attached Figure 1As shown, the lifting platform 8 is equipped with a support platform 6, the support platform 6 is equipped with a guide rail 5, and a support plate 7 is slidably mounted on the guide rail 5.

[0045] The support plate 7 can slide relative to the support platform 6. If an electric telescopic rod or a guide rail 5 is installed between the support platform 6 and the support plate 7, the support plate 7 can slide automatically relative to the support platform 6.

[0046] As attached Figure 1 As shown, it also includes a battery (not visible in the field of view, so it is not shown in the attached figure), which is housed within the frame 4.

[0047] The battery's function is to supply power to various electrical devices. A control unit is also installed within the chassis 4, electrically connected to the battery. All electrical equipment on the platform vehicle is controlled by the control unit. Similarly, devices such as infrared sensors, lidar, or ultrasonic probes can be installed on the chassis to automatically avoid obstacles while moving.

[0048] As attached Figure 1 As shown, it also includes a photovoltaic panel 9, which is rotatably mounted on the edge of the frame 4.

[0049] Specifically, the photovoltaic panel 9 can be installed on the edge of the frame 4 via an electric hinge, which can control the folding or unfolding of the photovoltaic panel 9 on the frame 4.
