Description

Technical Field

[0001] This utility model relates to the technical field of transport vehicles, and specifically to an electric transport vehicle. Background Technology

[0002] Electric pallet trucks are devices used for moving goods. During the process, the driver needs to constantly observe the position of the goods to achieve accurate and safe handling. However, due to the varying heights of the goods, the driver may not be able to observe the position of the goods well while sitting in the driver's seat, so he needs to stand up. However, the conventional seat structure will interfere with the driver's body distribution when standing, making it inconvenient for him to operate on the platform.

[0003] In existing technologies, to address the aforementioned issues, conventional seat structures are divided into a base frame, backrest, and seat. Rotating the seat prevents it from interfering with the driver's body. However, because the seat needs to rotate, it cannot achieve high-strength mechanical fixation. Position holding and switching can only be achieved through components such as hydraulic cylinders and pneumatic cylinders to prevent the seat from rotating arbitrarily due to the driver's own weight. However, keeping the hydraulic cylinders and pneumatic cylinders constantly in operation leads to excessive energy consumption. Furthermore, in existing technologies, to provide stability for drivers who are standing, an armrest is usually installed on the control panel's mask. The driver can hold onto the armrest to improve body stability and prevent misoperation. However, the installation of the armrest requires a split design for the mask, which is then assembled after the armrest is installed. This can cause the mask to warp at the joints during use. Additionally, a single mask requires multiple molding processes, resulting in low molding efficiency. Utility Model Content

[0004] This utility model addresses the aforementioned problems and aims to provide an electric transport vehicle that avoids interference between the seat and the standing driver, reduces overall energy consumption through mechanical support, and allows the face mask to be integrally molded, effectively improving the mask's aesthetics and increasing its molding efficiency.

[0005] To achieve the above objectives, this utility model provides an electric pallet truck, including a frame assembly, a fork assembly, a drive assembly, and a control assembly. The frame assembly includes a frame and a cab located at the rear of the frame. The fork assembly includes forks located at the front of the frame. The drive assembly includes a drive wheel assembly located at the bottom of the frame and a battery pack arranged on the frame. The control assembly includes an operating platform located within the cab.

[0006] The cockpit is equipped with a seat arranged opposite to the operating platform. The seat includes a base frame, a backrest, a seat, and a limiting member. The base frame is fixed to the side wall of the cockpit. The backrest is height-adjustable on the base frame. The seat includes a positioning frame and a cushion laid on it. The two ends of the positioning frame are rotatably fixed to the opposite sides of the bottom end of the backrest by mounting bolts. A limiting rod is provided in the middle of the positioning frame. The limiting member is height-adjustable below the limiting member.

[0007] The chair seat has:

[0008] Extended position: Extends horizontally to the outer side of the chair back to form a seating support surface;

[0009] Retractable position: Fits the front side of the chair back;

[0010] The operator can manually switch the position of the chair seat;

[0011] When the chair seat is in the unfolded position, the upper end of the limiting member can abut against the limiting rod to restrict the rotation of the chair seat;

[0012] The operating platform opposite the seat is equipped with armrests for the operator to hold.

[0013] According to the electric transport vehicle described above, the limiting component includes a positioning seat and a limiting bolt. The lower end of the limiting bolt passes through the positioning seat and is threadedly engaged with the positioning seat. The upper end of the limiting bolt is located directly below the limiting rod and can abut against the bottom of the limiting rod.

[0014] According to the electric transport vehicle described above, the limiting bolt is provided with a limiting disc and a first gripping part. The limiting disc is located on the top end of the limiting bolt, and the first gripping part is located on the bottom end of the limiting bolt. The diameters of the limiting disc and the first gripping part are both larger than the diameter of the limiting bolt.

[0015] According to the electric transport vehicle described above, the backrest includes a cushion and a sliding frame. The cushion is laid on the front side of the sliding frame and is vertically and flexibly mounted on the front side of the base frame via the sliding frame. The positioning frame is fixedly connected to the lower end of the sliding frame.

[0016] According to the electric transport vehicle described above, the seat further includes a lifting cylinder, which is arranged vertically on the rear side of the base frame. The base frame is provided with two vertically arranged through slots. The rear side of the sliding frame passes through the through slots and is provided with a mounting seat. The piston rod of the lifting cylinder is hinged to the mounting seat.

[0017] According to the electric transport vehicle described above, the chair back also includes a locking component, which includes a pin fixed on the sliding frame. The base frame is provided with a plurality of positioning holes arranged in a vertical direction, and the pin can be inserted into any of the positioning holes.

[0018] According to the above-described electric transport vehicle, the operating platform includes a face mask, multiple control units located on the face mask, and a mounting base located inside the face mask. The mounting base includes a mounting plate and a movable pressure plate. The mounting plate is fixedly connected to the inner wall of the face mask, and the movable pressure plate is detachably connected to the mounting plate and can be closed with the mounting plate to form a variable-diameter mounting groove. The handrail includes a grip section and a mounting section.

[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0039] like Figure 1-7 As shown, an electric pallet truck includes a frame assembly 100, a fork assembly 200, a drive assembly 300, and a control assembly 400.

[0040] The chassis assembly 100 includes a chassis 110 and a cab 120 located at the rear of the chassis 110. The chassis 110 provides support for other components. The fork assembly 200 includes forks 210 located at the front of the chassis 110. The drive assembly 300 includes a drive wheel set 310 located at the bottom of the chassis 110 and a battery pack 320 arranged on the chassis 110. The control assembly 400 includes an operating platform 410 located in the cab 120. The transport vehicle picks up goods with the movable forks 210 and then drives the entire vehicle to move through the drive wheel set 310 located at the bottom of the chassis 110, so that the goods can be transported to a predetermined position. The battery pack 320 supplies power to the drive wheel set 310, and the operating platform 410 can control the transport vehicle to perform corresponding actions.

[0041] Specifically, a seat 130 is arranged opposite to the operating platform 410 within the cockpit 120. The seat 130 includes a base frame 131, a backrest 132, a seat 133, and a limiting member 134. The backrest 132 is height-adjustable on the base frame 131. The seat 133 includes a positioning frame 133a and a seat cushion 133b laid on it. The two ends of the positioning frame 133a are rotatably fixed to opposite sides of the bottom of the backrest 132 by mounting bolts, allowing it to rise or fall synchronously with the backrest 132. A limiting rod 133c is located in the middle of the positioning frame 133a. The limiting member 134 is height-adjustable below the limiting rod 133c. Since both ends of the positioning frame 133a can rotate, as long as the limiting member 134 disengages from the limiting rod 133c, the positioning frame 133a can freely rotate to adjust its angle, achieving [the desired effect]. The seat 130 features stepless adjustment, thus having at least two positions: an extended position and a retracted position. In the extended position, the seat 133 extends horizontally to the outside of the frame, forming a seating support surface, suitable for the driver. In the retracted position, the seat 133 rests against the front of the backrest 132, ensuring no interference with the driver and allowing for switching between sitting and standing positions. The operator can manually adjust the position of the seat 133 by raising or lowering the limiting member 134 to meet different needs. When the seat 133 is in the extended position, the upper end of the limiting member 134 can abut against the limiting rod 133c. Since the rotation of the seat 133 will inevitably cause the limiting rod 133c to rotate, the abutment of the limiting member 134 can limit the rotation of the seat 133, achieving mechanical locking of the seat 133 and reducing energy consumption.

[0042] Furthermore, the limiting member 134 includes a positioning seat 134a and a limiting bolt 134b. The lower end of the limiting bolt 134b passes through the positioning seat 134a and is threadedly engaged with the positioning seat 134a. The upper end of the limiting bolt 134b is located directly below the limiting rod 133c and can abut against the bottom of the limiting rod 133c. Of course, when it is necessary to adjust the position of the chair seat 133, its height can also be adjusted by rotating the limiting bolt 134b to separate or abut against the limiting rod 133c, thereby achieving locking or unlocking.

[0043] Furthermore, the limiting bolt 134b is provided with a limiting disc 134c and a first gripping part 134d. The limiting disc 134c is located on the top of the limiting bolt 134b, and the first gripping part 134d is located on the bottom of the limiting bolt 134b. The diameters of both the limiting disc 134c and the first gripping part 134d are larger than the diameter of the limiting bolt 134b. When the limiting bolt 134b rises, it drives the limiting disc 134c to rise, thereby causing the limiting disc 134c to abut against the limiting rod 133c, thus increasing the contact area with the limiting rod 133c and reducing the stress points at each point. The first gripping part 134d is convenient for the operator to grip. Both can simultaneously prevent the limiting bolt 134b from disengaging from the positioning seat 134a.

[0044] In this embodiment, to ensure mechanical locking strength, the diameter of the limit bolt 134b4 is approximately 12mm and the length is approximately 100mm. The mounting bolt adopts the standard M8 specification, with a length of approximately 30mm, and is equipped with anti-loosening washers and nuts to ensure a firm and reliable connection.

[0045] Furthermore, the chair back 132 includes a cushion 132b and a sliding frame 132a. The cushion 132b is laid on the front side of the sliding frame 132a and is height-adjustable on the front side of the base frame 131 via the sliding frame 132a. The sliding frame 132a provides support for the cushion 132b and enables its sliding connection. The cushion 132b is made of a highly elastic material to provide comfortable back support. The sliding frame 132a is made of aluminum alloy, which is lightweight and high-strength, and facilitates height adjustment.

[0046] Furthermore, the seat 130 also includes a lifting cylinder 135, which is arranged vertically on the rear side of the base frame 131. The base frame 131 has two vertically arranged through slots, and a mounting seat 132c is provided on the rear side of the sliding frame 132a. The piston rod of the lifting cylinder 135 is hinged to the mounting seat 132c. The lifting cylinder 135 provides power for the lifting and lowering of the backrest 132, making it easier to lift and lower and saving labor. The maximum stroke of the lifting cylinder 135 is about 200mm, which can meet the needs of users of different heights.

[0047] In this embodiment, a plurality of guide wheel sets are provided on the rear side of the sliding frame 132a, arranged symmetrically in pairs. The guide wheel sets include a first guide wheel located on the front side of the base frame 131 and a second guide wheel located on the rear side of the base frame 131. The first guide wheel and the second guide wheel together form a guide groove. The side walls on both sides of the groove are movably engaged in the groove, and the mounting seat 132c is located between the two second guide wheels. In this embodiment, a total of four guide wheel sets are provided, which are arranged symmetrically in pairs in the horizontal direction on the rear side of the sliding frame 132a. The guide groove formed by the first guide wheel and the second guide wheel together provides a guiding function for the upward movement of the sliding frame 132a.

[0048] Furthermore, the seat 130 also includes a locking component, which includes a pin 132d fixed on the sliding frame 132a. The base frame 131 is provided with a plurality of positioning holes 131a arranged in the vertical direction. The pin 132d can be inserted into any positioning hole 131a to fix the sliding frame 132a. After the lifting cylinder 135 drives the sliding frame 132a to rise or fall to a preset height, the pin 132d can be inserted into the corresponding positioning hole 131a to achieve its positioning. In this embodiment, in order to facilitate the operation of the pin 132d, a plum blossom-shaped second grip is provided at the head of the pin 132d. The pin 132d in the locking component has a diameter of about 8mm and a length of about 50mm. The positioning holes 131a on the base frame 131 are spaced about 30mm apart, with a total of 5-7 holes to meet different height adjustment requirements.

[0049] In this embodiment, the pin 132d has a built-in return spring. When a force is applied to pull the pin 132d out of the positioning hole 131a, the return spring will be squeezed. After release, the return spring can drive the pin 132d to automatically reset.

[0050] In this embodiment, the base frame 131 is made of metal material, which has sufficient strength and stability to withstand the user's weight and the pressure of daily use.

[0051] In this embodiment, in order to prevent the driver from easily swaying when standing, a handrail 411 is provided on the operating platform 410. The handrail 411 is used for the operator to hold, especially when the driver is standing. The presence of the handrail 411 helps the driver stabilize his body and avoid misoperation caused by swaying.

[0052] Specifically, the operating platform 410 includes a face mask 412, multiple control units 413 located on the face mask 412, and a mounting base 414 located inside the face mask 412. The mounting base 414 includes a mounting plate 414a and a movable pressure plate 414b. The mounting plate 414a is fixedly connected to the inner wall of the face mask 412, and the movable pressure plate 414b is detachably connected to the mounting plate 414a and can be closed with the mounting plate 414a to form a variable-diameter mounting groove. That is, the movable pressure plate 414b can move towards or away from the mounting plate 414a to adjust the diameter of its mounting groove. The armrest 411 body includes a grip section and a mounting section. The grip section is located on the outside of the face mask 412, and the mounting section can be inserted into the mounting groove. In the inward movement, the movable pressure plate 414b can move away from the mounting plate 414a to enlarge the size of the mounting groove, making it easier for the mounting section to be inserted into the mounting groove. After the mounting section is inserted into the mounting groove, the movable pressure plate 414b can move towards the mounting plate 414a to clamp and fix the mounting section, thus achieving the installation and positioning of the handrail 411 body. This method can be used for handrail 411 bodies of different diameters. Since the faceplate 412 is not needed for positioning, in this embodiment, the faceplate 412 is integrally molded, which can effectively avoid the edge warping caused by splicing multiple pieces, improve the overall aesthetic performance of the faceplate 412, and at the same time reduce the molding difficulty of the faceplate 412, avoid molding multiple shells separately, and improve molding efficiency.

[0053] Furthermore, the movable pressure plate 414b is detachably connected to the mounting plate 414a via multiple adjusting bolts 414c. After the mounting section is inserted into the mounting groove, the multiple adjusting bolts 414c can be tightened to clamp and position the mounting section. In order to facilitate installation and disassembly, the face shield 412 has an opening on one side, which corresponds to the nuts of the multiple adjusting bolts 414c. A detachable baffle 412b is provided inside the opening. During the installation process, the baffle 412b is removed, the multiple adjusting bolts 414c are tightened, and then the baffle 412b is installed.

[0054] Furthermore, to achieve complete locking of the mounting section, a first locking plane 411a is provided on one side of the mounting section, and a second locking plane is provided on one side of the mounting plate 414a. When the mounting section is inserted into the mounting groove, the first locking plane 411a can fit against the second locking plane, thereby preventing the mounting section from rotating in the mounting groove. In this embodiment, taking the mounting section as an example, when the pressure plate and the mounting plate 414a are used for fixing, the mounting section is relatively easy to rotate, which can lead to unstable positioning of the handrail 411 body. Especially after the driver applies force to the handrail 411 body, it can easily cause a safety accident. However, after the first locking plane 411a and the second locking plane are set to abut against each other, it is completely locked and cannot rotate.

[0055] In this embodiment, an electric pallet truck is disclosed, including a frame assembly 100, a fork assembly 200, a drive assembly 300, and a control assembly 400. The frame assembly 100 includes a frame 110 and a driver's cab 120 located at the rear of the frame 110. The driver's cab 120 is provided with an operating platform 410 and a seat 130 arranged opposite to the operating platform 410. The seat 130 includes a base frame 131, a backrest 132, a seat 133, and a limiting member 134. The backrest 132 is height-adjustable on the base frame 131. The seat 133 includes a positioning frame 133a and a seat cushion 133b laid on it. The two ends of the positioning frame 133a are rotatably fixed to the two opposite ends of the bottom of the backrest 132 by mounting bolts. On the side, a limiting rod 133c is provided in the middle of the positioning frame 133a. A limiting member 134 is elliptically and vertically positioned below the limiting rod 133c. The seat 130 has an unfolded position and a retracted position. In the unfolded position, the seat 133 extends horizontally to the outside of the frame to form a seating support surface, which is suitable for the driver to sit in. In the retracted position, the seat 133 is close to the front side of the backrest 132. When the seat 133 is in the unfolded position, the upper end of the limiting member 134 can abut against the limiting rod 133c. Since the rotation of the seat 133 will definitely drive the limiting rod 133c to rotate, the abutment of the limiting member 134 can limit the rotation of the seat 133 and mechanically lock the seat 133, reducing energy consumption.
