Detailed Implementation
[0030] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.
[0031] In related technologies, the structural realization of unmanned transportation engineering equipment generally falls into two main categories: the first is to directly install an intelligent driving system on a vehicle with a driver's cab to achieve unmanned transportation; the second is to redesign the exterior of a driverless vehicle and then install an intelligent driving system to achieve unmanned transportation. While the first method can achieve unmanned transportation, it suffers from problems such as cumbersome on-site modifications, unsuitable installation locations for the intelligent driving equipment, insufficient installation space, and high vehicle costs. The second method is more in line with the current structural form of unmanned transportation vehicles and can achieve the desired functions, but its excessive pursuit of aesthetic design increases manufacturing costs, installation difficulty, and the complexity of daily maintenance. Furthermore, due to the cabinless design, recovery after a vehicle malfunction is more difficult.
[0032] Based on this, see Figure 1 , Figure 3 This disclosure provides a short-range handheld remote controller, which can also be used in engineering transportation equipment. The short-range handheld remote controller includes a main housing 1 and a display screen 5. The main housing 1 has multiple operation buttons 4. The display screen 5 is configured to display different images in response to commands from the operation buttons 4, wherein the angle between the plane containing the display side of the display screen 5 and the top surface of the main housing 1 is between 120° and 150°. For example, the angle between the plane containing the display side of the display screen 5 and the top surface of the main housing 1 is 120°, 130°, 140°, or 150°.
[0033] It is understood that in this embodiment, the main housing 1 has a control unit corresponding to the operation button 4. This control unit can send different signals under the command of the operation button 4, so that the remote control can issue different commands. This application will not elaborate on this.
[0034] In this embodiment, by setting the angle between the plane where the display screen 5 is located and the top surface of the main housing 1 to between 120° and 150°, repeated experiments have shown that at this angle, the screen 5 can display images that can be seen by the staff at all angles, which improves the accuracy of the staff's operation and allows for a rapid response when encountering special situations during operation, thus improving the safety of the operation.
[0035] It should be noted that in other embodiments of this disclosure, the angle between the plane where the display screen 5 is located and the top surface of the main housing 1 is not limited to this, and this application will not elaborate further.
[0036] In some embodiments of this disclosure, remote control and vehicle interconnection, as well as structural design and layout optimization, can be achieved through controller local area network input and output methods such as receiver sending data to controller and controller sending data to receiver.
[0037] In some embodiments of this disclosure, the main housing 1 has a first mounting groove 11; the display screen 5 is disposed within the first mounting groove 11. This arrangement can improve the stability of the connection between the display screen 5 and the main housing 1, and prevent the display screen 5 from being easily damaged due to shaking during operation.
[0038] Furthermore, the connection wiring between the display screen 5 and the internal control unit of the main housing 1 can be placed in the second mounting slot 13 to fully hide the connection wiring and improve the aesthetics of the remote control.
[0039] In some embodiments of this disclosure, the operation button 4 may include a first self-resetting side button switch 41, a multi-position self-locking rotary switch 42, a display screen button 43, a circular base single-axis rocker 44, an emergency stop button 45, a two-position self-locking toggle switch 46, a three-position self-locking toggle switch 47, and a second self-resetting side button switch 48.

The first self-resetting side switch 41 includes an emergency brake button 411, an emergency parking button 412, and an emergency steering button 413, arranged sequentially along the width direction of the main housing 1. The emergency brake button 411 primarily functions to brake the engineering transport equipment by pressing it. It is also a self-resetting button, meaning it automatically returns to its initial position after being pressed. The emergency parking button 412 primarily functions to park the engineering transport equipment by pressing it. It is also a self-resetting button, meaning it automatically returns to its initial position after being pressed. The emergency steering button 413 primarily functions to steer the engineering transport equipment by pressing it. It is also a self-resetting button, meaning it automatically returns to its initial position after being pressed.
[0041] See Figure 1A multi-position self-locking rotary switch 42 is located in the middle of the top surface of the main housing 1. The multi-position self-locking rotary switch 42 includes a units digit selection key 421 and a tens digit selection key 422, which are arranged sequentially along the width direction of the main housing 1. The function of the units digit selection key 421 and the tens digit selection key 422 is to cooperate with each other to select the corresponding engineering transportation equipment.
[0042] See Figure 5 The display screen buttons 43 include a first button 431, a second button 432, a third button 433, and a fourth button 434. The display screen 5 also includes a first indicator light 435 and a second indicator light 436. The first indicator light 435 indicates that the remote control is in an abnormal state. The second indicator light 436 indicates that the remote control is in a normal state. The first button 431 allows for vehicle selection by long-pressing it. The second button 432 allows for exiting the vehicle selection interface without saving the selected vehicle number by long-pressing it. The third button 433 saves the selected vehicle number. The fourth button 434 is used to turn the display screen 5 on or off.
[0043] See Figure 1 The circular base single-axis rocker arm 44 includes a left single-axis rocker arm 441 and a right single-axis rocker arm 442. The left single-axis rocker arm 441 and the right single-axis rocker arm 442 are respectively located on both sides of the multi-position self-locking rotary switch 42. The left single-axis rocker arm 441 can be used to move the engineering transport equipment left and right by rocking it. The right single-axis rocker arm 442 can be used to accelerate and brake the engineering transport equipment by moving it forward and backward.
[0044] See Figure 3 An emergency stop button 45 is located on one side of the main housing 1, and the emergency stop button 45 and the first self-resetting side key switch 41 are symmetrically arranged about the width of the main housing 1. The function of the emergency stop button 45 is to enable emergency stopping of the engineering transport equipment by pressing the emergency stop button 45.
[0045] The second self-resetting side switch 48 is located on the same side as the emergency stop button 45. The second self-resetting side switch 48 may include a switch button 481, a start button 482, and an off button 483 arranged along the width direction of the main housing 1. The switch button 481 is used to turn the engineering transport equipment connected to the remote control on or off by pressing the switch button 481. The start button 482 is used to start the engineering equipment connected to the remote control. The off button 483 is used to turn off the engineering transport equipment connected to the remote control.
[0046] See Figure 1The two-position self-locking toggle switch 46 includes a driving toggle switch 461, a parking toggle switch 462, a power-on toggle switch 463, a lighting toggle switch 464, a movement toggle switch 465, and a stop toggle switch 466, all arranged along the length of the main housing 1. The driving toggle switch 461 functions as follows: moving it upwards puts the driving vehicle into the driving brake open state, and moving it downwards puts the driving vehicle into the driving brake closed state. The parking toggle switch 462 functions as follows: moving it upwards puts the driving vehicle into the parking brake open state, and moving it downwards puts the driving vehicle into the parking brake closed state. The power-on toggle switch 463 functions as follows: moving it upwards puts the driving vehicle into the power-on open state, and moving it downwards puts the driving vehicle into the power-off closed state. The lighting toggle switch 464 functions as follows: moving it upwards puts the driving vehicle lighting into the open state, and moving it downwards puts the driving vehicle lighting into the closed state. The function of the motion toggle switch 465 is to: move the vehicle forward by moving it upward, and move it backward by moving it downward. The function of the stop toggle switch 466 is to: move the vehicle to a one-to-one stop state by moving it upward, and move it downward to a complete stop state by moving it downward. The three-position self-locking toggle switch 47 includes a lifting toggle switch 471 located between the stop toggle switch 466 and the motion toggle switch 465. The function of the lifting toggle switch 471 is to: move the vehicle upward by moving it upward, move it downward by moving it downward, and place the toggle lever between the upper and lower lifting states to place the vehicle in an intermediate lifting state.
[0047] See Figure 3 In some embodiments of this disclosure, one side of the main housing 1 has a second mounting groove 13 for accommodating the emergency stop button 45; and the side of the emergency stop button 45 away from the sidewall of the second mounting groove 13 is on the same horizontal plane as the side of the main housing 1 with the second mounting groove 13. This arrangement can prevent accidental triggering of the emergency stop button 45 during operation and improve the safety of workers.
[0048] In some embodiments of this disclosure, the sidewall of the second mounting groove 13 has a clearance notch 131 that exposes a portion of the emergency stop button 45.
[0049] It is understood that in this embodiment, the second mounting groove 13 has a first sidewall 132, a second sidewall 134, and a third sidewall 133, wherein the first sidewall 132, the second sidewall 134, and the third sidewall 133 are connected sequentially, and the first sidewall 132 and the third sidewall 133 are symmetrically arranged about the thickness direction of the main housing 1, thus exposing the bottom surface of the main housing 1 and forming a clearance notch 131. The clearance notch 131 provided in this embodiment not only prevents accidental contact by workers but also facilitates rapid response by workers, further ensuring the safety of workers during operation.
[0050] Of course, in other embodiments of this disclosure, the location of the clearance notch 131 may also be other locations of the main housing 1, which will not be elaborated further in this disclosure.
[0051] See Figure 1 In some embodiments of this disclosure, the remote control also includes an operating handle 2. The operating handle 2 is mounted on the main housing 1, and a gripping space is formed between the operating handle 2 and the top surface of the main housing 1. One end of the display screen 5 is connected to the operating handle 2, and the other end is connected to the side wall of the first mounting groove 11. The operating handle 2 serves several purposes: firstly, it allows the operator to place their hand within the gripping space when using the remote control, facilitating operation; secondly, it surrounds the operation buttons 4 on the main housing 1, reducing accidental touches; and thirdly, it protects the operation buttons 4 during transport, preventing damage and extending the lifespan of the remote control.
[0052] In some embodiments of this disclosure, the operating handle 2 has an operating notch 21. Specifically, the operating handle 2 is arc-shaped, and the side closer to the operator's use has an operating notch 21. This design facilitates operation by the operator while protecting the operating buttons 4 on the main housing 1.
[0053] See Figure 1 , Figure 2 In some embodiments of this disclosure, the main housing 1 has an illumination toggle switch 464; the main housing 1 corresponding to the operation notch 21 has an extension 12, and the extension 12 has a clearance groove 121 corresponding to the illumination toggle switch 464.
[0054] See Figure 1 In some embodiments of this disclosure, the remote control also includes a shoulder strap 3; the operating handle 2 has a hanging ring 22, one end of the shoulder strap 3 is detachably connected to the hanging ring 22 on one side of the operating handle 2, and the other end of the shoulder strap 3 is detachably connected to the hanging ring 22 on the other side of the operating handle 2. With this configuration, when the operator holds the remote control for operation, the operator connects one end of the shoulder strap 3 to the hanging ring 22 on one end of the operating handle 2, and the other end of the shoulder strap 3 to the hanging ring 22 on the other end of the operating handle 2. This allows the operator to operate the remote control while it is suspended around their neck in front of their body, reducing the risk of the remote control slipping and falling, and also allowing the operator to wear the remote control diagonally across their body.
[0055] See Figure 3 , Figure 4 In some embodiments of this disclosure, the operating handle 2 has a grip portion 23.
[0056] As an example, the grip 23 may include multiple protrusions 231 located on the side of the operating handle 2 near the housing. A recessed area is formed between the protrusions 231, which is a placement area for the operator's fingers. This improves the stability of the remote control operation and prevents the remote control from slipping and falling.
[0057] Furthermore, in some embodiments, the protrusion 231 has an arc surface, so that the recessed area formed by adjacent protrusions 231 forms a good transition, improving the comfort of the operator.
[0058] This application also provides a partial method of using a short-range handheld remote control (e.g., a method of selecting a car using the remote control):
[0059] Specifically, the display screen button 43 has a first button 431 and a second button 432. When selecting a vehicle, press and hold the first button 431 to enter the vehicle selection operation. A multi-position self-locking rotary switch 42 (including a units digit selection key 421 and a tens digit selection key 422) is used to select the vehicle number (the combination range of vehicle numbers is between 0 and 99). For example, if vehicle number 99 has been selected, rotate the first button 431 to the position corresponding to the number 9, and also rotate the second button 432 to the position corresponding to the number 9.
[0060] If you select the desired vehicle number, you can press and hold the third button 433 to save the selected vehicle number (meaning the remote control will continue to use the currently saved vehicle number even after power failure). After successfully saving, if you want to cancel the selected vehicle number and exit the current vehicle selection interface, press and hold the second button 432 to exit the vehicle selection interface without saving the selected vehicle number. This operation will not disconnect the currently connected vehicle from the remote control.
[0061] This disclosure further provides an engineering transportation device, which includes the aforementioned short-range handheld remote controller.
[0062] In some embodiments of this disclosure, the engineering transport equipment can be an unmanned engineering transport equipment. As an example, the engineering transport equipment can be a wide-body dump truck (unmanned).
[0063] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
