Description

TECHNICAL FIELD

[0001] The present application relates to the field of automated mechanical equipment, in particular to the structure optimization and space design of an industrial vehicle operation control device. BACKGROUND

[0002] Industrial vehicles refer to power-driven motor vehicles used to carry, push, tow, lift, stack or store various cargos. Common industrial vehicles include forklifts, side forklifts, tow trucks, carrying trucks, stackers, etc.

[0003] Industrial vehicles include unmanned AGVs and manned vehicles. The former does not require an operator to operate the vehicle, and the entire journey is completed by automatic guidance and positioning technology. The latter requires an operator to manually operate the vehicle by using a controller, such as a steering wheel or a control panel.

[0004] Industrial vehicles are different from passenger cars, which are designed for fixed sitting positions and relatively fixed operators. Industrial vehicle operators are different workers with different heights and body sizes, and need a wider and more flexible viewing angle to ensure the safety of cargo loading and unloading. Specifically, when the viewing angle is limited, the operator may make mistakes during the forklift loading process, which may damage the cargo and the rack and cause safety problems. Therefore, a multi-dimensional adjustable steering wheel steering operation device for industrial vehicles is disclosed in Chinese patent document CN202111480357.0. The operation device includes front-back and up-down adjustments. The front-back adjustment relies on a front-back sliding structure, and the up-down adjustment relies on an angle swing bracket, which is connected to the operation device at one end and hinged to the main frame at the other end to achieve vertical swinging of the operation device.

[0005] However, this method can adjust the position of the steering wheel, but has the following technical defects: on the one hand, the "rotation plus length extension" adjustment method changes the relative angle between the control device and the hand, causing inconvenience in operation. On the other hand, in order to obtain a larger vertical adjustment range, the length of the angle swing bracket needs to be increased to increase the swing radius, which occupies a large space in the length direction of the cockpit. Such an increase in space not only reduces the comfort of the operator, but also increases the length of the industrial vehicle, thereby increasing the turning radius, which is not suitable for narrow aisles in warehouse environments. SUMMARY

[0006] The present application provides a controller adjustment device, a controller and a vehicle suitable for industrial vehicles. The controller can be adjusted in the horizontal and vertical directions, can adapt to different operators, is flexible and convenient to adjust, has low space requirements, improves the comfort of the operator and optimizes the size of the vehicle.

[0012] As a preferred embodiment of the present invention, a bolt clamp is provided on the rod body, the bolt head is spherical, and a ejection portion is provided between adjacent positioning holes. The bolt head, the ejection portion, the positioning hole and the elastic member are configured so that when the sliding block and the locking device are raised or lowered, the bolt head leaves the positioning hole, the ejection portion overcomes the elastic force of the elastic member, and pushes the bolt tail into the bolt clamp.

[0013] As a preferred embodiment of the present invention, the operating rod extends in the vertical direction and passes through the sliding block, and the locking device extends in the horizontal direction and is located between the back frame and the operating rod.

[0014] As a preferred embodiment of the present invention, a latch is connected to the operating rod, and the adjusting device further includes a spring having one end in contact with the top surface of the sliding block and the other end in contact with the latch.

[0015] As a preferred embodiment of the present invention, a button is connected to the top surface of the shaft.

[0016] As a preferred embodiment of the present invention, the fixing frame further includes a base frame connected to the fixing frame and a guide rod installed on the base frame and extending in a vertical direction, and the vertical slide passes through the guide rod.

[0017] As the preferred of the present application, the guide rod is provided with a reset spring, one end of which is in contact with the top surface of the base frame, and the other end is in contact with the bottom surface of the vertical slide frame.

[0018] As the preferred of the present application, the guide rod comprises a guide main rod and a guide sub rod with a smaller caliber than the guide main rod, and the reset spring is mounted on the guide sub rod.

[0019] As the preferred of the present application, the guide main rod is farther away from the back frame in the horizontal direction than the guide sub rod.

[0020] As the preferred of the present application, the vertical slide frame further comprises a cross frame and a middle connecting frame, which extends in the vertical direction and is connected to the cross frame and the middle connecting frame at both ends respectively; the horizontal slide frame is in sliding connection with the cross frame, and is locked in position relative to the cross frame by a locking bolt.

[0023] The vehicle comprises a main body and a walking device, characterized in that it further comprises the controller according to the preceding claim.

[0024] In summary, the present application has the following advantages: 1. The horizontal position and the vertical position of the operating device can be flexibly adjusted, so that operators of various body types can be accommodated. The vertical position adjustment is not the rotation and lifting of the prior art, but the direct lifting in the vertical direction. Such lifting mode can reduce the length of the distance occupied under the premise of ensuring the lifting range.

[0025] 2. Regardless of the up-down and front-back adjustment, the angle of the operating device remains unchanged, so that the operating personnel can have a comfortable and stable operating angle.

[0026] 3. The inclined connecting frame is inclined and gradually rises in the direction close to the human body. Such inclined mode brings better observation field of view, so that the observation line of the operator in the front and lower direction is not blocked.

[0027] 4. The guide main rod is thicker, providing more stable guiding effect. And the guide main rod is closer to the human body, as the main guiding point and support point, it can provide a longer guiding horizontal force arm, which is beneficial to the lifting and sliding stability of the sliding block 21.

[0028] 5. The guide sub rod adopts a thin rod, which is convenient for installing a reset spring with a suitable caliber.

[0029] 6. The bolt head is spherical and fits the shape of the positioning hole. On the one hand, the bolt head fits into the positioning hole more snugly. On the other hand, when the user simultaneously holds the sliding block and the operating rod to lift or lower, the user overcomes the elastic force of the elastic part and the bolt head detaches from the positioning hole. 7. The ejector allows the bolt tail to enter the bolt card, and the operating rod cannot be raised or lowered relative to the sliding block. That is, the user cannot pull out the operating rod alone in the unlocked position. The lifting and lowering feel feedback is obvious, avoiding user error.

[0030] 8. The spring of the spring rod allows the operating rod to return to its original position quickly. The rod body replaces the bolt clamp and contacts the bolt tail. The bolt head is fixed in the positioning hole, and the height position of the sliding block is quickly locked. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.

[0035] The following description provides examples, and is not intended to limit the scope, applicability or example set forth in the claims. Alterations and changes in the function and arrangements of elements could be made without deviating from the spirit and scope of the description. Various examples can omit, substitute, or add various procedures or components as appropriate. For instance, the methods described can be performed in an order different than described, and various steps can be added, omitted, or combined. Also, features described with respect to some examples can be combined in other examples.

[0036] Embodiment 1, a controller adjustment device for industrial vehicles, as shown in Figure 1 and Figure 2 , mainly contains four components, namely, a fixed frame 1, a vertical sliding frame 2, an operating lever 3, and a control connecting frame 4. The fixed frame 1 can be regarded as a fixed component, which can be fixedly connected to the main vehicle body of the vehicle. The vertical sliding frame 2 can be raised and lowered in the vertical direction along the fixed frame 1 under the operation of the operating lever 3. The control connecting frame 4 is connected with the operating device and moves in the horizontal front-back direction relative to the vertical sliding frame 2.

[0037] Through such a setting, first, the horizontal position and vertical position of the operating device can be flexibly adjusted, so that operators of various body types can be suitable. Second, the vertical position adjustment is not the rotation and lifting of the prior art, but direct lifting in the vertical direction. Such a lifting manner can reduce the length direction distance occupation under the premise of ensuring the lifting amplitude. Third, such an operating manner makes the angle of the operating device 9, such as the steering wheel, unchanged regardless of the up-down and front-back adjustment, so that the operator can have a comfortable and stable operating angle.

[0038] As shown in Figure 1 , Figure 2 and Figure 3 , the horizontal adjustment depends on the cooperation of the control connecting frame 4 and the vertical sliding frame 2. Specifically, the vertical sliding frame 2 contains a horizontal frame 23 extending in the horizontal direction. The horizontal sliding frame 41 also extends in the horizontal front-back direction and is slidingly connected with the horizontal frame 23. After sliding into position, the user tightens the locking bolt 8, which can be threadedly connected with the horizontal frame 23 and abuts against the lower surface of the horizontal sliding frame 41, completing the locking. At the end of the horizontal sliding frame 41 close to the human body, i.e., the right end in Figure 1 , a diagonal connecting frame 42 is arranged, which is inclined and gradually rises in the direction close to the human body. Such an inclined manner brings better observation field of view, so that the observation line of the operator in the front and lower direction is not blocked.

[0039] The fixed frame 1 includes a back frame 11 and a bottom frame 12, which extend in the vertical and horizontal directions respectively. A guide rod 13 is also vertically connected to the bottom frame 12. The sliding block 21 is slidably connected to the back frame 11 and relies on the guide rod 13 as a guide during the sliding process. The guide rod 13 is divided into a thicker guide main rod 131 and a thinner guide auxiliary rod 132. Figure 1 As shown, the guide main rod 131 is thicker, providing a more stable guiding effect. Furthermore, the guide main rod 131 is closer to the body and farther away from the back frame 11. As the main guiding point and support point, it can provide a longer guide lateral force arm, facilitating the stable lifting and sliding of the sliding block 21. The guide auxiliary rod 132 is a thin rod, which facilitates the installation of a return spring 5 of appropriate diameter.

[0040] The cross frame 23 and the sliding block 21 are connected by the central connecting frame 22. Clearly, in this embodiment, the height adjustment of the operating device 9 is actually the height adjustment of the sliding block 21. The height locking of the sliding block 21 is achieved by the locking device 6. The locking device 6 can be composed of conventional fixed blocks, fixed pins, inserted shafts, clamping blocks, and other components, as long as it can fix the sliding block 21 at different heights on the back frame 11.

[0041] In this embodiment, the back frame 11 is provided with a plurality of positioning holes 14 arranged at different heights, and the locking device 6 adopts a double-headed pin structure. The movement of the locking device 6 is achieved by Figure 2 This is achieved by using the operating lever 3 in the figure.

[0042] Specifically, such as Figure 3 As shown, the button 32 is mounted on the upper end of the shaft 31, and the user moves the entire shaft 31 downward by pressing it. Figure 4 As shown, a recessed latch 33 is provided on the rod body 31. The user presses the operating rod 3 so that the locking device 6 is flush with the latch 33. At this time, the adjustment state is entered, and the user holds the sliding block 21 and the operating rod 3 at the same time to lift and lower them.

[0043] There are ejection parts 15 between adjacent positioning holes 14, and the positioning holes 14 and the ejection parts 15 are arranged alternately in the height direction. A hollow inner cavity 24 is opened in the middle of the sliding block 21. In addition to the locking device 6, an elastic member 25 is also arranged in the middle. The elastic member 25 can be an elastic pad, an elastic ring or other components. In this embodiment, a spring is used. One end of the spring contacts the wall of the inner cavity 24, and the other end contacts the bolt head 61, thereby giving the locking device 6 a close proximity to the back frame 11, that is, Figure 4The force is to the left. The head 61 is a ball, which fits the opening of the positioning hole 14. This shape makes the head 61 fit into the positioning hole 14, and when the user holds the sliding block 21 and the operating rod 3, the head 61 is separated from the positioning hole 14, and the top 15 gives the head 61 a force to the right, so that the tail 62 enters the clamping 33, as shown. Figure 4 The force is to the right, so that the tail 62 enters the clamping 33, as shown. At this time, the operating rod 3, the sliding block 21, and the locking device 6 are locked in the height direction, and the operating rod 3 cannot be lifted relative to the sliding block 21, that is, the user cannot pull out the operating rod 3 alone in the non-locking position, avoiding user misoperation. Figure 5

[0044] The user continues to move the sliding block 21 and the operating rod 3 together until the specified height. The head 61 is opposite the positioning hole 14, and the head 61 enters the positioning hole 14 under the influence of the elastic element 25, and the tail 62 is naturally separated from the clamping 33. At this time, the operating rod 3 and the sliding block 21 are no longer in a locked state, and the user can return the operating rod 3.

[0045] When the user operates the operating rod 3 and the sliding block 21, the head 61 will enter the different positioning holes 14 under the action of the spring 25, and the sound feedback can be clearly heard.

[0046] In this case, as shown in the figure, a pin shaft (not shown in the figure) is arranged on the rod body 31, and the other end of the elastic rod spring 7 is in contact with the pin shaft. Therefore, when the operating rod 3 and the sliding block 21 are no longer in a locked state, the user releases his hand, the elastic rod spring 7 quickly returns the operating rod 3, the rod body 31 replaces the clamping 33 and the tail 62, and the head 61 is fixed in the positioning hole 14, and the height position of the sliding block 21 is quickly locked. Figure 5 As shown in the figures, a reset spring 5 is arranged on the guide sub-rod 132, and one end of the reset spring 5 is in contact with the bottom frame 12, and the other end is in contact with the lower surface of the sliding block 21. When the user needs to move the sliding block 21 upward, the elastic force of the reset spring 5 can reduce the user's burden and improve the operation convenience.
