Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, and more specifically, to an integrated weighing and handling vehicle. Background Technology

[0002] Existing technology, such as CN218860267U, discloses an electronic forklift scale in the field of weighing equipment. It includes two U-shaped base plates distributed on both sides. An elliptical plate is connected to the front end of both U-shaped base plates, and each rear end is equipped with a rear wheel fixed to the bottom. A multi-angle rotating steering shaft is inserted at the center of the elliptical plate. Several synchronously steerable front wheels are connected to the bottom of the steering shaft. A lever that can be moved back and forth is also connected to the side of the steering shaft. A cover plate is suspended above both U-shaped base plates, and several sensors supported and fixed to the bottom of the cover plate are installed inside the U-shaped base plates. By adding multiple sensors to detect the weight of the loaded items within the U-shaped base plate positions for loading and unloading, the system not only functions as a forklift for hauling goods but also as an electronic scale for weighing items. This allows users to know the weight of the loaded items during handling, facilitating item distribution and handling.

[0003] As electronic forklift scales become more widely used, users demand products that are highly integrated, practical, and easier to use and operate. Utility Model Content

[0004] This utility model overcomes the shortcomings of the prior art. Its structural design is reasonable, and multiple components are integrated and installed, making the product more practical and convenient to operate.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An integrated weighing and handling vehicle includes a base plate, rear wheels mounted on the base plate, a cover plate mounted on the base plate, a weighing module located between the base plate and the cover plate, a backrest frame fixedly connected to the base plate, a rocker arm mounted in the backrest frame, a support base hinged to the rocker arm, an electric front wheel assembly rotatably mounted on the support base, a handle assembly connected to the electric front wheel assembly, a hydraulic cylinder mounted on the support base and connected to the backrest frame, and an instrument panel mounted on the backrest frame. The electric front wheel assembly includes a front wheel, a drive motor, and a gearbox. The gearbox has a bearing seat located in the support base. A partition is provided on the backrest frame, and a side hole is provided on the backrest frame. A battery located above the partition is installed in the side hole. An oil pump is provided on the backrest frame below the partition. A support frame is provided on one side of the hydraulic cylinder, and a controller is mounted on the support frame.

[0006] By adopting the above technical solution, the base plate and backrest frame are fixed together, and the oil pump drives the oil cylinder to move, thereby realizing the raising and lowering of the base plate and backrest frame. Specifically, when the oil cylinder extends or retracts, the rocker arm rotates relative to the support seat, driving the backrest frame and base plate to rise and fall. The battery can be independently inserted into the side hole and limited and supported by the partition plate. This, along with the oil pump's position, makes the overall structural layout more rational. The battery can power the oil pump, controller, and weighing module, while the controller can be electrically connected to the control buttons on the handle assembly for controlling the oil pump.

[0007] Preferably, the handle assembly includes a handle joint seat fixedly connected to the bearing seat, a handle fork hinged to the handle joint seat, a handle bar mounted above the handle fork, and a gas spring connecting the handle joint seat and the handle bar.

[0008] By adopting the above technical solution, a control button is specifically installed on the handle bar. Pressing the control button can realize the lifting and lowering operation of the base plate and backrest frame, while the gas spring can provide buffering and elastic restoring force when the handle bar and handle fork rotate relative to the handle joint seat.

[0009] Preferably, one end of the gas spring is hinged to the handle rod, and the other end of the gas spring is hinged to the handle joint seat. The handle fork is provided with a connecting end, which is provided with a protrusion, an arc segment, and a groove located between the protrusion and the arc segment. A pin located in the groove is installed on the handle joint seat.

[0010] By adopting the above technical solution, the purpose of the above structure is mainly for the installation of gas spring. Since the gas spring needs to have a certain preload when it is installed, the existing installation requires a large force. However, this solution, by setting the groove and the pin, only requires pressing the handle fork and handle rod against the handle joint seat to compress the gas spring, and then installing the pin on the handle joint seat so that the pin is located in the groove.

[0011] Preferably, the weighing module includes a sensor and a weighing block. The sensor is fixedly mounted on a base plate, and the weighing block is mounted on the sensor and partially exposed. The sensor has a mounting groove for accommodating the weighing block. The bottom surface of the weighing block is an arc shape that is higher on both sides and lower in the middle. The middle of the bottom surface of the weighing block abuts against the bottom of the mounting groove, and there are gaps between the two sides of the bottom surface of the weighing block and the bottom of the mounting groove. The bottom surface of the weighing block has a mounting hole, and the sensor is located below the mounting groove and a fastener connected to the mounting hole passes through it.

[0012] By adopting the above technical solution, the purpose of the above structure is to address the issue that, during actual use, the goods transported on the cover plate have a certain weight. When the weight of the goods is too heavy, the cover plate may deform, causing errors in the weighing of the weighing block. By setting gaps between the bottom sides of the weighing block and the bottom of the mounting groove, these gaps allow the cover plate to deform to a certain extent, thereby ensuring the weighing accuracy of the weighing block.

[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] like Figure 1-6As shown, an integrated weighing and handling vehicle includes a base plate 1, rear wheels 11 mounted on the base plate 1, a cover plate 12 mounted on the base plate 1, a weighing module 2 located between the base plate 1 and the cover plate 12, a backrest frame 3 fixedly connected to the base plate 1, a rocker arm 31 mounted in the backrest frame 3, a support base 4 hinged to the rocker arm 31, an electric front wheel assembly 5 rotatably mounted on the support base 4, a handle assembly 6 connected to the electric front wheel assembly 5, a hydraulic cylinder 41 mounted on the support base 4 and connected to the backrest frame 3, and a weighing module 2 located between the base plate 1 and the cover plate 12. The instrument panel 32 on the frame 3, the electric front wheel assembly 5 including the front wheel 51, the drive motor 52 and the gearbox 53, the gearbox 53 having a bearing seat 54 located in the support 4, the backrest frame 3 is provided with a partition 33, the backrest frame 3 is provided with a side hole 34, the side hole 34 is installed with a battery 35 located above the partition 33, the backrest frame 3 is provided with an oil pump 36 located below the partition 33, the oil cylinder 41 is provided with a support frame 42 on one side, and a controller 43 is installed on the support frame 42.

[0017] By adopting the above technical solution, since the base plate 1 and the backrest frame 3 are fixed together, the oil pump 36 can drive the oil cylinder 41 to move, thereby realizing the lifting and lowering of the base plate 1 and the backrest frame 3. Specifically, when the oil cylinder 41 extends or retracts, the rocker arm 31 will rotate relative to the support seat 4, thereby driving the backrest frame 3 and the base plate 1 to lift and lower. Among them, the battery 35 can be independently inserted into the side hole 34 and limited and supported by the partition 33. The position setting of the oil pump 36 makes the overall structural layout more reasonable. The battery 35 can power the oil pump 36, the controller 43, and the weighing module 2, and the controller 43 can be electrically connected to the control button on the handle assembly 6 for controlling the oil pump 36.

[0018] The handle assembly 6 includes a handle joint seat 61 fixedly connected to the bearing seat 54, a handle fork 62 hinged to the handle joint seat 61, a handle rod 63 mounted above the handle fork 62, and a gas spring 64 connecting the handle joint seat 61 and the handle rod 63. Specifically, a control button is installed on the handle rod 63. Pressing the control button allows for the raising and lowering of the base plate 1 and the backrest frame 3. The gas spring 64 provides cushioning and spring-like restoring force when the handle rod 63 and the handle fork 62 rotate relative to the handle joint seat 61.

[0019] One end of the gas spring 64 is hinged to the handle rod 63, and the other end is hinged to the handle joint seat 61. The handle fork 62 is provided with a connecting end 65, which has a protrusion 66, an arc-shaped segment 67, and a groove 68 located between the protrusion 66 and the arc-shaped segment 67. A pin 69 located in the groove 68 is installed on the handle joint seat 61. The purpose of the above structure is mainly for the installation of the gas spring 64. Since the gas spring 64 needs to have a certain preload when installed, the existing installation requires a large force. However, with the groove 68 and pin 69 in this solution, it is only necessary to operate the handle fork 62 and the handle rod 63 to press down relative to the handle joint seat 61, compressing the gas spring 64, and then install the pin 69 onto the handle joint seat 61, so that the pin 69 is located in the recess.

[0020] The weighing module 2 includes a sensor 21 and a weighing block 22. The sensor 21 is fixedly mounted on the base plate 1. The weighing block 22 is mounted on the sensor 21 and partially exposed above it. The sensor 21 has a mounting groove 23 for accommodating the weighing block 22. The bottom surface 24 of the weighing block 22 is arc-shaped, higher on both sides and lower in the middle. The bottom surface 24 of the weighing block 22 abuts against the bottom of the mounting groove 23 in the middle. There is a gap 25 between the two sides of the bottom surface 24 of the weighing block 22 and the bottom of the mounting groove 23. The bottom surface 24 of the weighing block 22 has a mounting hole 26. The sensor 21 is located below the mounting groove 23 and is connected to a fastener 27 in the mounting hole 26. The purpose of the above structure is to prevent the weighing block 22 from making errors during actual use, as the goods transported on the cover plate 12 have a certain weight. When the weight of the goods is too heavy, the cover plate 12 may deform, causing errors during weighing. By setting a gap 25 between the two sides of the bottom surface 24 of the weighing block 22 and the bottom of the mounting groove 23, the cover plate 12 is allowed to undergo a certain deformation, thereby ensuring the weighing accuracy of the weighing block 22.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
