Description

Technical Field

[0001] The present application belongs to the technical field of heavy trucks, and specifically relates to an automatic fully open cargo box and a dump truck. Background Art

[0002] A dump truck refers to a vehicle that unloads goods by itself through hydraulic or mechanical lifting. It includes a vehicle body and a cargo box located at the rear of the vehicle body. Since the cargo box can automatically tilt to a certain angle for unloading, it greatly saves unloading time and labor, shortens the transportation cycle, improves production efficiency and reduces transportation costs.

[0003] There are two common ways of unloading cargo boxes, one is backward tipping and the other is sideways tipping. For a cargo box that tips backward, it includes a box body with an open rear, a door panel hinged to the rear of the box body, and a locking mechanism provided on the box body for locking the rear panel. When the cargo box tips over for unloading, it is necessary to first control the locking mechanism so that the locking mechanism unlocks the rear panel, and then the box tips backward. At this time, the rear panel rotates relative to the box body under the action of its own gravity, so that the rear panel can rotate relative to the box body when the box tilts backward. During the tipping process, the opening of the box is gradually opened, causing the goods in the box to slide down due to the tipping action of the box. When the backward tipping angle of the box is small, the angle between the rear plate and the box is small, which causes the rear plate to block the goods that slide down in the box, thereby affecting the unloading efficiency of the cargo box. In addition, since the rear plate relies on its own gravity to rotate relative to the box to open the opening of the box, the position of the rear plate cannot be controlled manually, which leads to poor flexibility of the cargo box. Utility Model Content

[0004] The present application provides an automatic fully open cargo box and a dump truck to improve the unloading efficiency of the cargo box and increase the flexibility of the cargo box.

[0005] The technical solution adopted in this application is:

[0006] An automatic fully open cargo box comprises a box body with an opening at the rear and a rear plate arranged at the rear of the box body, a connecting piece is arranged on the top of the rear plate, and the connecting piece is hinged to the box body through a hinge shaft, so that the rear plate has an open position for opening the opening and a closed position for closing the opening, the box body is provided with a driving piece for driving the connecting piece to rotate, so that the rear plate moves between the open position and the closed position under the action of the driving piece, the box body has a rear wall and a top wall, and the distance from the hinge shaft to the rear wall is equal to the distance from the hinge shaft to the top wall, so that when the rear plate is in the open position, at least part of the rear plate abuts against the top of the box body.

[0007] By adopting the above-mentioned technical solution, when unloading the cargo box in the present application, the driving member is first started, and then the driving member drives the connecting member to make the connecting member and the hinge shaft rotate relative to each other. At the same time, the connecting member drives the rear plate to rotate, so that the rear plate moves from the closed position to the open position, and then the box body is tilted backwards to make the goods in the box body slide out, so as to complete the unloading of the cargo box.

[0008] The automatic fully open cargo box in the present application is provided with a driving member for driving the connecting member to rotate, so that the opening angle of the rear panel can be manually controlled, so as to increase the flexibility of the cargo box and meet the various needs of users; and the opening angle of the rear panel is not limited by the backward tilting angle of the box body. That is to say, no matter how much the box body tilts backward, the rear panel can be driven by the driving member to the maximum opening angle, so as to avoid the situation where the rear panel blocks the goods due to the small backward tilting angle of the box body, thereby ensuring the unloading efficiency of the cargo box; in addition, when the rear panel is in the open position, at least part of the rear panel contacts the top of the box body, so that the top of the box body can support the rear panel, so as to reduce the load on the connecting member, thereby increasing the stability of the rear panel and increasing the safety of the rear panel, thereby increasing the safety of the cargo box when unloading.

[0009] Optionally, the connecting member includes a connecting portion arranged at the top of the rear plate and a linkage portion arranged at the connecting portion, the hinge shaft is arranged at the linkage portion, and the linkage portion is located on a side of the rear plate facing the box body.

[0010] By adopting the above technical solution, since the linkage part is located on the side of the rear plate facing the box body, it is achieved that after the rear plate moves to the open position under the action of the driving member, at least part of the rear plate abuts against the top wall of the box body, so that the top wall of the box body can support the rear plate, thereby reducing the load on the connecting member, thereby increasing the service life of the connecting member and increasing the safety of the rear plate.

[0011] Optionally, the driving member has a piston rod, and the connecting member also includes a transmission part, the hinge shaft passes through the transmission part, the transmission part has a first hinge position hinged to the connecting part and a second hinge position hinged to the piston rod, and the second hinge position is offset from the projection of the hinge shaft toward the horizontal plane.

[0012] By adopting the above technical solution, since the second hinge is located at a projection offset of the hinge axis toward the horizontal plane, and the piston rod is hinged at the second hinge position, the stroke required for the piston rod to move when the driving member drives the rear plate can be reduced, thereby reducing the space reserved for arranging the driving member. At the same time, the installation of the driving member is not restricted by space, so as to facilitate the modification and optimization of the existing cargo box.

[0013] Optionally, the second hinge position is located on a side of the hinge axis facing the outside of the box body, and the driving member is located below the second hinge position.

[0014] By adopting the above technical scheme, since the second hinge position is located on the side of the hinge axis facing the outside of the box body, and the driving member is located below the second hinge position, when the piston rod extends, the rear plate moves from the closed position to the open position, and when the piston rod retracts, the rear plate moves from the open position to the closed position. Moreover, since the space below the second hinge position is larger, arranging the driving member below the second hinge position is easier than arranging it above the second hinge position, thereby achieving the effect of facilitating the installation of the driving member, and at the same time enabling the driving member to avoid the transmission part to ensure the normal opening or closing of the rear plate.

[0015] Optionally, the box body includes a bottom plate and vertical plates arranged on both sides of the bottom plate, and the width of the rear plate is less than or equal to the distance between the two vertical plates.

[0016] By adopting the above technical solution, since the width of the rear panel is less than or equal to the distance between the two vertical panels, the rear panel and the top of the vertical panel can be avoided to avoid the situation where the rear panel cannot be fully opened due to interference between the rear panel and the top of the vertical panel, thereby ensuring the opening angle of the rear panel to ensure the unloading efficiency of the cargo box.

[0017] Optionally, convex ribs are provided on inner sides of the two vertical panels, and when the rear panel is in the open position, the rear panel abuts against the convex ribs.

[0018] By adopting the above technical solution, when the rear plate is in the open position, the rear plate contacts the convex ribs so that the convex ribs support the rear plate, thereby avoiding the need to bend the two vertical plates in a direction close to each other, thereby reducing the difficulty of producing the vertical plates and improving the production efficiency of the cargo box.

[0019] Optionally, the automatic fully open cargo box further includes a wireless receiver for controlling the opening and closing of the driving member and a wireless controller connected to the wireless receiver signal.

[0020] By adopting the above-mentioned technical scheme, since the automatic fully open cargo box also includes a wireless receiver for controlling the opening and closing of the drive member and a wireless controller connected to the wireless receiver signal, the user can control the opening or closing of the rear panel from the outside of the dump truck to increase the flexibility of opening or closing the rear panel. At the same time, it can avoid the situation where the rear panel has not been opened yet and the box body has already tipped over backwards to a certain extent, thereby avoiding the situation where the dump truck tipped over backwards, and thus can increase the safety of the dump truck to a certain extent.

[0021] Optionally, the rear plate is provided with a first inclinometer, and the bottom of the box is provided with a second inclinometer; when the rear plate is in a vertical state, the first inclinometer is 0 degrees, and when the box is in a horizontal state, the second inclinometer is 0 degrees; the automatic fully open cargo box also includes an alarm component connected to the signals of the first inclinometer and the second inclinometer; when the box tilts backward and the degree difference between the first inclinometer and the second inclinometer is less than or equal to 10 degrees, the alarm component sounds an alarm.

[0022] By adopting the above technical solution, when unloading the cargo box, the driving member is first started, and then the driving member drives the connecting member, so that the connecting member drives the rear plate to move, so that the rear plate moves from the closed position to the open position, and the angle of the rear plate changes, so that the degree difference between the first angle meter and the second angle meter gradually increases, and when the rear plate moves to the open position, the degree difference between the first angle meter and the second angle meter is equal to 90 degrees. If the rear plate is between the closed position and the open position, and the degree difference between the first angle meter and the second angle meter is less than or equal to 10 degrees, when the box body tilts backward at this time, the alarm component will sound an alarm to warn the driver that the opening angle of the rear plate is small and there is a risk of unloading, thereby reminding the driver to open the rear plate again, thereby increasing the safety of the cargo box when unloading.

[0023] The present application also discloses a dump truck, comprising a vehicle body and an automatic fully open cargo box as described above, wherein the vehicle body has a cab, and the alarm component comprises an angle display instrument provided in the cab and a first alarm device provided in the cab, wherein the first alarm device sounds an alarm when the box body tips over backwards and the degree difference between the first angle meter and the second angle meter is less than or equal to 10 degrees.

[0024] By adopting the above technical solution, since an angle display is provided in the cab, the driver can check the degree difference between the first angle meter and the second angle meter at any time, so that the driver can control the opening and closing of the rear panel, and at the same time it is convenient for the driver to open the rear panel to the required angle, so as to achieve the effect of facilitating the control of the opening angle of the rear panel; in addition, since the first alarm is provided in the cab, the driver can perceive it at the first time when the first alarm sounds an alarm, so as to shorten the driver's response time, thereby further avoiding the occurrence of safety accidents and further increasing the safety of the dump truck when unloading.

[0025] Optionally, the alarm component further comprises a second alarm device provided on the vehicle body or the box, and when the degree difference between the first inclinometer and the second inclinometer changes, the second alarm device emits an alarm sound.

[0026] By adopting the above technical solution, when the rear plate is opened or closed, the rear plate and the box body rotate relative to each other, which causes the degree difference between the first angle meter and the second angle meter to change. At this time, the second alarm sounds an alarm to remind the staff around the dump truck that the rear plate is moving, so as to avoid safety accidents, thereby further increasing the safety of the dump truck when unloading. At the same time, the second alarm is arranged on the vehicle body or the box body, so that when the second alarm sounds an alarm, the staff around the dump truck can hear it immediately, thereby shortening the staff's reaction time, thereby further increasing the safety of the dump truck when unloading.

[0043] When unloading the cargo box in the present application, the driving member 4 is first started, and then the driving member 4 drives the connecting member 3 to make the connecting member 3 and the hinge shaft 321 rotate relative to each other. At the same time, the connecting member 3 drives the rear plate 2 to rotate, so that the rear plate 2 moves from the closed position to the open position, and then the box body 1 is tilted backward to make the goods in the box body 1 slide down to complete the unloading of the cargo box.

[0044] The automatic fully open cargo box in the present application is provided with a driving member 4 for driving the connecting member 3 to rotate, so that the opening angle of the rear panel 2 can be manually controlled to increase the flexibility of the cargo box and meet the various needs of users; and the opening angle of the rear panel 2 is not limited by the backward tilting angle of the box body 1, that is, no matter how much the box body 1 tilts backward, the rear panel 2 can be driven to the maximum opening angle by the driving member 4 to avoid the situation where the rear panel 2 blocks the goods due to the small backward tilting angle of the box body 1, thereby ensuring the unloading efficiency of the cargo box; in addition, when the rear panel 2 is in the open position, at least part of the rear panel 2 contacts the top of the box body 1, so that the top of the box body 1 can support the rear panel 2, so as to reduce the load of the connecting member 3, thereby increasing the stability of the rear panel 2 and increasing the safety of the rear panel 2, thereby increasing the safety of the cargo box when unloading.

[0045] It should be noted that the open position mentioned in the present application refers to the position where the rear panel 2 moves to the maximum opening angle, that is, the position where the rear panel 2 rotates 90 degrees to fully open the opening of the box body 1.

[0046] In a preferred embodiment, referring to Figure 1 and Figure 2 The box body 1 includes a bottom plate 11 and vertical plates 12 arranged on both sides of the bottom plate 11. The width of the rear plate 2 is less than or equal to the distance between the two vertical plates 12, so that the rear plate 2 and the top of the vertical plates 12 can form an avoidance to avoid the rear plate 2 and the top of the vertical plates 12 interfering with each other, resulting in the rear plate 2 being unable to be fully opened, thereby ensuring the opening angle of the rear plate 2 to ensure the unloading efficiency of the cargo box.

[0047] The present application does not make any specific limitation on the structure of the vertical panels 12. Preferably, convex ribs are provided on the inner sides of the two vertical panels 12. When the rear panel 2 is in the open position, the rear panel 2 abuts against the convex ribs so that the convex ribs support the rear panel 2, thereby avoiding the need to bend the two vertical panels 12 in a direction close to each other, thereby reducing the difficulty of producing the vertical panels 12 and improving the production efficiency of the cargo box.

[0048] In other embodiments, the tops of the two vertical panels 12 may be bent toward each other, so that when the rear panel 2 is in the open position, the rear panel 2 abuts against the tops of the bent portions of the two vertical panels 12 .

[0049] Furthermore, the two vertical panels 12 are extended toward the side where the rear panel 2 is located, so that when the rear panel 2 is in the closed position, the vertical panels 12 can cover the rear panel 2, and sealing strips are provided on the opposite sides of the rear panel 2. Then, when the rear panel 2 is in the closed position, the sealing strips abut against the vertical panels 12 to offset the gap between the rear panel 2 and the vertical panels 12, thereby preventing the goods from falling when the cargo box is used to transport the goods.

[0050] In a preferred embodiment, referring to Figure 1 and Figure 2 The connecting member 3 includes a connecting portion 31 arranged on the top of the rear panel 2 and a linkage portion 32 arranged on the connecting portion 31, a hinge shaft 321 is arranged on the linkage portion 32, and the linkage portion 32 is located on the side of the rear panel 2 facing the box body 1, thereby achieving that after the rear panel 2 moves to the open position under the action of the driving member 4, at least part of the rear panel 2 is in contact with the top wall of the box body 1, so that the top wall of the box body 1 can support the rear panel 2, thereby reducing the load of the connecting member 3, so as to increase the service life of the connecting member 3 and increase the safety of the rear panel 2.

[0051] Better, refer to Figure 3 The connecting portion 31 includes a first section 311 connected to the rear plate 2 and extending upward, a second section 312 connected to the first section 311 and extending laterally toward the outside of the rear plate 2, and a third section 313 connected to the second section 312 and extending toward the forward direction of the dump truck, and the top projection of the third section 313 is located on the outside of the box body 1, so that the driving member 4 can be installed on the outside of the box body 1 to avoid the driving member 4 occupying the internal space of the box body 1, so as to ensure the capacity of the cargo box to hold the cargo, and at the same time avoid the cargo from causing damage to the driving member 4.

[0052] The present application does not specifically limit the structure of the driving member 4, and it can adopt any one of the following embodiments:

[0053] Embodiment 1. In this embodiment, the driving member 4 is a stepper motor. The output shaft of the stepper motor and the hinge shaft 321 are both provided with gears. The two gears are meshed and connected in transmission. The gear provided on the hinge shaft 321 is fixedly connected to the linkage part 32, so that when the stepper motor is working, the output shaft of the stepper motor drives the gear to rotate, and then the two gears rotate relative to each other. The gear provided on the linkage part 32 drives the linkage part 32 to move, and the linkage part 32 drives the connecting part 31 to move, so that the connecting part 31 drives the rear plate 2 to move, so that the rear plate 2 moves between the open position and the closed position.

[0054] In this embodiment, the linkage portion 32 is fixedly connected to the connection portion 31 , and the two may be an integral structure or may be fixed by fasteners.

[0055] Embodiment 2, in this embodiment, refer to Figure 1 and Figure 2 The driving member 4 is any one of a hydraulic cylinder, a pneumatic cylinder or an electric push rod. Preferably, in this embodiment, the driving member 4 is deployed as a hydraulic cylinder.

[0056] Furthermore, the cylinder body of the driving member 4 is hinged to the box body 1, and the connecting member 3 also includes a transmission part 33, and the hinge shaft 321 passes through the transmission part 33. The transmission part 33 has a first hinge position 331 hinged to the connecting part 31 and a second hinge position 332 hinged to the piston rod. The second hinge position 332 and the projection of the hinge shaft 321 toward the horizontal plane are offset, which can reduce the stroke required for the piston rod to move when the driving member 4 drives the rear plate 2, thereby reducing the space reserved for arranging the driving member 4, and at the same time making the installation of the driving member 4 not limited by space, so as to facilitate the modification and optimization of the existing cargo box.

[0057] In this embodiment, the connection relationship between the connecting portion 31 and the linkage portion 32 is not specifically limited. Figure 1 and Figure 2 The connecting portion 31 is hinged to the linkage portion 32, and there is a gap between the hinge position of the connecting portion 31 and the linkage portion 32 and the hinge position of the transmission portion 33 and the connecting portion 31, so that the connecting portion 31, the linkage portion 32 and the transmission portion 33 together form a triangle, so as to increase the connection stability between the linkage portion 32 and the connecting portion 31, thereby increasing the stability of the rear plate 2. In other embodiments, the connecting portion 31 can also be fixedly connected to the linkage portion 32.

[0058] The present application does not specifically limit the structure of the transmission part 33. Preferably, refer to Figure 1 and Figure 2 The transmission part 33 has a triangular plate structure, i.e., the hinge shaft 321 is disposed through one of the corners of the transmission part 33, the other corner of the transmission part 33 is a first hinge position 331, and the other corner of the transmission part 33 is a second hinge position 332, so as to further increase the stability of the rear panel 2 and ensure the stability of the rear panel 2 when it moves between the open position and the closed position. In other implementation examples, the transmission part 33 can also be a triangular structure composed of three rods.

[0059] The present application does not specifically limit the positional relationship between the second hinge position 332 and the hinge axis 321. Preferably, refer to Figure 1 and Figure 2The second hinge position 332 is located on the side of the hinge shaft 321 facing the outside of the box body 1, and the driving member 4 is located below the second hinge position 332, so that when the piston rod extends, the rear plate 2 moves from the closed position to the open position, and when the piston rod retracts, the rear plate 2 moves from the open position to the closed position. Since the space below the second hinge position 332 is larger, the driving member 4 is arranged below the second hinge position 332 compared to arranging it above the second hinge position 332, thereby achieving the effect of facilitating the installation of the driving member 4, and at the same time enabling the driving member 4 to form a avoidance with the transmission part 33 to ensure the normal opening or closing of the rear plate 2.

[0060] In other implementation examples, the second hinge position 332 is located on the side of the hinge axis 321 away from the outside of the box body 1, and the driving member 4 is located below the second hinge position 332, so that when the piston rod retracts, the rear plate 2 moves from the closed position to the open position, and when the piston rod extends, the rear plate 2 moves from the open position to the closed position.

[0061] In a preferred embodiment, the automatic fully open cargo box also includes a wireless receiver for controlling the opening and closing of the driving member 4 and a wireless controller connected to the wireless receiver signal, so that the user can control the opening or closing of the rear panel 2 outside the dump truck to increase the flexibility of opening or closing the rear panel 2, and at the same time, it can avoid the situation that the box body 1 has tipped backwards before the rear panel 2 is opened, thereby avoiding the situation that the dump truck tipped backwards, and thus can increase the safety of the dump truck to a certain extent. In addition, the wireless controller can also be integrated into the remote control key of the dump truck to give the remote control key new functions and improve the user experience.

[0062] In a preferred embodiment, the rear plate 2 is provided with a first inclinometer so that the first inclinometer can detect the rotation angle of the rear plate 2, and a second inclinometer is provided at the bottom of the box body 1 so that the second inclinometer can detect the angle of the box body 1 tilting backward. When the rear plate 2 is in a vertical state, the first inclinometer is 0 degrees, and when the box body 1 is in a horizontal state, the second inclinometer is 0 degrees. The automatic fully open cargo box also includes an alarm component connected to the signals of the first inclinometer and the second inclinometer. When the box body 1 tilts backward and the degree difference between the first inclinometer and the second inclinometer is less than or equal to 10 degrees, the alarm component sends out an alarm.

[0063] It should be noted that the first inclinometer and the second inclinometer are not divided into positive and negative degrees, that is, the first inclinometer and the second inclinometer are both displayed in positive degrees.

[0064] Specifically, when unloading the cargo box, the driving member 4 is started first, and then the driving member 4 drives the connecting member 3, so that the connecting member 3 drives the rear panel 2 to move, so that the rear panel 2 moves from the closed position to the open position, and the angle of the rear panel 2 changes, so that the degree difference between the first angle meter and the second angle meter gradually increases, and when the rear panel 2 moves to the open position, the degree difference between the first angle meter and the second angle meter is equal to 90 degrees. If the rear panel 2 is between the closed position and the open position, and the degree difference between the first angle meter and the second angle meter is less than or equal to 10 degrees, when the box body 1 tilts backward at this time, the alarm component will sound an alarm to warn the user that the opening angle of the rear panel 2 is small and there is a risk of unloading, so that the driver opens the rear panel 2 again, thereby increasing the safety of the cargo box when unloading.

[0065] Of course, the difference between the first inclinometer and the second inclinometer may be less than or equal to 10 degrees and the second inclinometer may be 5 degrees. When the box body 1 continues to tip over backwards, the alarm component sounds an alarm.

[0066] The present application also discloses a dump truck, which includes a vehicle body and the above-mentioned automatic fully open cargo box, wherein the vehicle body has a cab, and the alarm component includes an angle display instrument provided in the cab and a first alarm provided in the cab, and the angle display instrument is connected to the first angle meter and the second angle meter signal, so that the degree measured by the first angle meter and the degree measured by the second angle meter can be displayed on the angle display instrument, and the angle display instrument can display the degree difference between the first angle meter and the second angle meter, so that the driver can control the opening and closing of the rear plate 2, and at the same time, it is convenient for the driver to open the rear plate 2 to the desired angle, so as to achieve the effect of facilitating the control of the opening angle of the rear plate 2. When the box body 1 tilts backward and the degree difference between the first angle meter and the second angle meter is less than or equal to 10 degrees, the first alarm device sounds an alarm.

[0067] Since the first alarm is arranged in the cab, the driver can be aware of it immediately when the first alarm sounds an alarm, thereby shortening the driver's response time, thereby further avoiding the occurrence of safety accidents and further increasing the safety of the dump truck when unloading.

[0068] The present application does not specifically limit the manner in which the first alarm sounds an alarm; it may be a horn, so that the first alarm warns the driver of danger by producing an alarm sound; it may also be a vibrator, so that the first alarm warns the driver of danger by producing a vibration.

[0069] In a preferred embodiment, the alarm component further comprises a second alarm device arranged on the vehicle body or the box body 1, and when the degree difference between the first inclinometer and the second inclinometer changes, the second alarm device emits an alarm sound.

[0070] When the rear plate 2 is opened or closed, the rear plate 2 and the box body 1 rotate relative to each other, which causes the degree difference between the first angle meter and the second angle meter to change. At this time, the second alarm sounds an alarm to remind the staff around the dump truck that the rear plate 2 is moving, so as to avoid safety accidents, thereby further increasing the safety of the dump truck when unloading. At the same time, the second alarm is arranged on the vehicle body or the box body 1, so that when the second alarm sounds an alarm, the staff around the dump truck can hear it immediately, thereby shortening the staff's reaction time, thereby further increasing the safety of the dump truck when unloading.

[0071] Preferably, the second alarm is a speaker and is disposed on the vehicle body, so that the vehicle body can shield the second alarm to prevent external objects from causing damage to the second alarm.

[0072] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0073] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0074] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
