However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0031] Example 1
[0032] Reference Figure 1 , Figure 2 This is the first embodiment of the present invention, which provides a steering protection device for a two-way wide-body dump truck, characterized in that it includes:
[0033] Specifically, the protective unit 100 includes a protective box 101, a power assembly 102, and a protective plate 103. The protective unit 100 is located at the corner of the truck bed, the power assembly 102 is located inside the protective box 101, and the protective plate 103 is located on one side of the protective box 101.
[0034] The cleaning unit 200 includes a handle 201, a lever 202, a transmission assembly 203, and a cleaning rod 204. The cleaning unit 200 is located inside the protective box 101. The handle 201 is located at one end of the lever 202. The other end of the lever 202 extends through the transmission assembly 203 into the protective box 101. One side of the cleaning rod 204 is connected to the transmission assembly 203.
[0035] Furthermore, the protective unit 100 is a core component of the present invention, used to protect the corners of the truck bed from damage. The protective unit 100 includes a protective housing 101, a power assembly 102, and a protective plate 103. The protective housing 101 has a robust structure capable of withstanding collisions and external impacts to protect the corners of the truck bed. The power assembly 102 is installed inside the protective housing 101, providing the necessary power and driving force to the protective unit 100. The protective plate 103 is located on one side of the protective housing 101, used to reinforce the structure of the protective unit 100 and improve overall stability. The power assembly 102 connects to the protective plate 103, providing a power source for the rotation of the protective plate 103.
[0036] The sweeping unit 200 is another key component used to clean debris from the truck bed. A handle 201 is mounted on one end of a lever 202 to provide a convenient grip for the operator. The other end of the lever 202 extends into the protective housing 101 via a transmission assembly 203. The transmission assembly 203 transmits the operator's sweeping motion to the interior of the protective housing 101 through its rotation. One side of the sweeping lever 204 is connected to the transmission assembly 203, allowing the operator to control the movement of the sweeping lever 204 by operating the handle 201 and the lever 202. Compared to the protective unit 100, the sweeping unit 200 is installed inside the protective housing 101, effectively protecting it from external environmental interference and damage.
[0037] In use, the operator can first transmit the power source of the handle 201 to the transmission component 203, so that the transmission component 203 transmits the force to the lever 202, thereby driving the sweeping bar 204 to sweep the top of the protective box 101. While sweeping, it can also control the steering of the protective plate 103. After the sweeping work is completed, an external power source, such as a motor, is used. The motor is located outside the protective box 101, and the output shaft of the motor is connected to the power component 102, which can provide a power source for the steering of the protective plate 103. The protective plate 103 can be steered according to actual needs.
[0038] In summary, the present invention provides a simple and reliable protective unit and a cleaning unit that can effectively protect the corners of the truck bed and facilitate cleaning operations, thereby improving work efficiency and safety.
[0039] Example 2
[0040] Reference Figures 3-5 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0041] Furthermore, the protective box 101 includes a storage slot 101a and a storage cavity 101b. The storage slot 101a is located inside the protective box 101, and the storage cavity 101b is located at the bottom of the storage slot 101a. The storage cavity 101b is provided to provide additional storage space for the power assembly 102.
[0042] Furthermore, the power assembly 102 is located within the storage cavity 101b. The power assembly 102 includes a gear disk 102a, transmission gears 102b, a support rod 102c, and a steering rod 102d. A mainspring 102a-1 is connected to one side of the gear disk 102a. The mainspring 102a-1 provides a buffering function for the steering rod 102d. One end of the steering rod 102d is connected to a first spring rod 102d-1. One end of the steering rod 102d passes through the gear disk 102a and connects to one end of the first spring rod 102d-1. The other end of 2d-1 is connected to the protective plate 103; one end of the steering rod 102d passes through the gear disk 102a and is connected to one end of the first spring rod 102d-1, while the other end of the first spring rod 102d-1 is connected to the protective plate 103, thereby achieving support and stability for the steering rod 102d. The function of the first spring rod 102d-1 is to provide a buffering effect during the movement of the steering rod 102d, and to obtain stable support through its connection with the protective plate 103.
[0043] Furthermore, one end of the support rod 102c is connected to the transmission gear 102b, and the gear disk 102a meshes with the transmission gear 102b. Both the transmission gear 102b and the support rod 102c are located at the bottom of the gear disk 102a. This arrangement allows the transmission gear 102b to fit tightly with the gear disk 102a, and through its connection with the support rod 102c, it can maintain the stability and reliability of the power assembly 102 during operation.
[0044] Furthermore, the transmission gear 102b includes a first transmission gear 102b-1 and a second transmission gear 102b-2. A first bearing 102b-1a is provided on one side of the first transmission gear 102b-1, and a first tooth 102b-1b is provided on the other side of the first transmission gear 102b-1. The first transmission gear 102b-1 meshes with one side of the gear disk 102a.
[0045] The second transmission gear 102b-2 has a second bearing 102b-2a on one side and a second tooth 102b-2b on the other side. The second transmission gear 102b-2 meshes with the other side of the gear disk 102a. This design allows the transmission gear 102b to be more firmly attached to the gear disk 102a, and the bearing provides a smoother rotation effect.
[0046] The bearing rod 102c includes a limiting ring 102c-1 and a fixing rod 102c-2. The limiting ring 102c-1 is sleeved on the outside of the bearing rod 102c, and the fixing rod 102c-2 is located inside the bearing rod 102c. A through groove 102c-3 is also provided on one side of the bearing rod 102c. A protrusion 102c-2a is fixed on one side of the fixing rod 102c-2. The other end of the protrusion 102c-2a extends into the through groove 102c-3, and the protrusion 102c-2a abuts against the limiting ring 102c-1. At this time, the bearing rod 102c and the second transmission gear... The fixed rod 102c-2 in the middle of 102b-2 is also provided with an elastic element. The elastic element is used to provide a reset function. The two sides of the bearing rod 102c are respectively convex teeth. The two sides of the bearing rod 102c mesh with the first tooth 102b-1b and the second tooth 102b-2b. This design allows the bearing rod 102c to be stably connected to and support the transmission tooth 102b. Furthermore, the position and range of motion of the bearing rod 102c are ensured by the setting of the limiting ring 102c-1 and the fixed rod 102c-2.
[0047] Furthermore, a storage plate 101c is provided on one side of the protective box 101. The storage plate 101c is located on one side of the storage cavity 101b. The storage plate 101c is also provided with a sliding groove 101c-1. The storage plate 101c is also provided with a spring 101c-2. The spring 101c-2 is located in the sliding groove 101c-1. The other end of the steering rod 102d is connected to one side of the storage plate 101c.
[0048] In use, an external motor is connected as the power output. The motor output shaft is connected to one side of the first transmission gear 102b-1. Because the first transmission gear 102b-1 meshes with the left side of the gear disk 102a, it drives the gear disk 102a to rotate clockwise, which in turn drives the steering rod 102d connected to the gear disk 102a to rotate clockwise. At the same time, the first spring rod 102d-1 connected to the steering rod 102d plays a partial buffering role. Then, the force is transmitted to the protective plate 103 connected to the first spring rod 102d-1, which drives the protective plate to rotate clockwise, protecting one side of the truck bed.
[0049] Example 3
[0050] Reference Figures 3-5 This is the third embodiment of the present invention, which is based on the previous embodiment.
[0051] Furthermore, one end of the handle 201 is also connected to a second spring rod 201a, and a stop block 201b is connected to one side of the second spring rod 201a. The stop block 201b abuts against one side of the shelf 101c.
[0052] Furthermore, the lever 202 includes a clamping block 202a at one end, and the other end of the lever 202 passes through the sliding groove 101c-1 and is fixed to one side of the stop block 201b. The outer side of the limiting ring 102c-1 is located inside the clamping block 202a.
[0053] Furthermore, the transmission assembly 203 includes a transmission rod 203a and a bevel gear 203b. The bevel gear 203b includes a first bevel gear 203b-1, a second bevel gear 203b-2, a third bevel gear 203b-3, and a fourth bevel gear 203b-4. The first bevel gear 203b-1 and the second bevel gear 203b-2 mesh with the third bevel gear 203b-3 and the fourth bevel gear 203b-4, respectively.
[0054] Furthermore, the transmission rod 203a also includes a path groove 203a-1, which is wound around the outside of the transmission rod 203a. The first bevel gear 203b-1 and the second bevel gear 203b-2 are respectively connected to both sides of the transmission rod 203a, and the second spring rod 201a passes through the transmission rod 203a.
[0055] Furthermore, four cleaning rods 204 are provided simultaneously, evenly distributed on the top of the storage slot 101a. Each cleaning rod 204 includes a cleaning blade 204a. One end of the cleaning rod 204 passes through the storage cavity 101b and extends into the storage slot 101a to connect with the cleaning blade 204a. The cleaning blade 204a is located in the storage slot 101a.
[0056] Furthermore, the sweeping rod 204 also includes a transmission wheel 204b, which is sleeved on one end of the sweeping rod 204. The transmission wheel 204b meshes with the third bevel gear 203b-3, and the sweeping rod 204 and the third bevel gear 203b-3 are connected by a track. The track transmits the force of the third bevel gear 203b-3 to the sweeping rod 204 to rotate, thereby realizing the transmission of force.
[0057] During use, if staff find debris or gravel in the storage compartment 101a, failure to clean it promptly will affect the normal operation of the protective unit 100. In this case, staff can manually pull the handle 201 to transmit force to the second spring rod 201a. At this time, the second spring rod 201a is slidably connected to the path groove 203a-1 on the transmission rod 203a, thereby causing the transmission rod 203a to start rotating. When staff need to clean up the gravel and need to protect the left side, they can move the handle 201 to the left into the slot 101d on the side of the protective box 101, causing the lever 202 to move to the left, thereby actuating the limiting ring 102c-1 on the bearing rod 102c. Move to the left. At this time, the convex tooth on the left side of the bearing rod 102c meshes with the first tooth 102b-1b on the first transmission tooth 102b-1. When the motor is started, the motor output shaft is connected to one side of the first transmission tooth 102b-1. Because the first transmission tooth 102b-1 meshes with the left side of the gear disk 102a, it drives the gear disk 102a to rotate clockwise, which drives the steering rod 102d connected to the gear disk 102a to rotate clockwise. At the same time, the first spring rod 102d-1 connected to the steering rod 102d plays a part of the buffering role, and then transmits the force to the protective plate 103 connected to the first spring rod 102d-1, which drives the protective plate to turn clockwise and protect the left side of the truck bed.
[0058] When protection of the right side is required, by moving the handle 201 to the left into the slot 101d on one side of the protective box 101, the lever 202 is moved to the right, thereby causing the limiting ring 102c-1 on the bearing rod 102c to move to the right. The limiting ring 102c-1 presses against the protrusion 102c-2a, causing the elastic element on the fixed rod 102c-2 to compress. At this time, the protrusion on the right side of the bearing rod 102c engages with the second tooth 102b-2b on the second transmission tooth 102b-2. When the motor is started, the motor... The output shaft is connected to one side of the second transmission gear 102b-2. Because the first transmission gear 102b-1 meshes with the right side of the gear disk 102a, it drives the gear disk 102a to rotate counterclockwise, which in turn drives the steering rod 102d connected to the gear disk 102a to rotate clockwise. At the same time, the first spring rod 102d-1 connected to the steering rod 102d plays a partial buffering role, and then transmits the force to the protective plate 103 connected to the first spring rod 102d-1, which drives the protective plate to rotate counterclockwise to protect the right side of the truck bed.
[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
