[0034] Detailed Implementation

[0035] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0036] The rear protective device of this utility model is described below with reference to the accompanying drawings.

[0037] like Figures 1 to 3As shown, this utility model provides a rear protection device, which includes a fixed frame and a pedal assembly. The fixed frame includes a frame body 10 and a fixed pedal 20. The frame body 10 is used to connect to the rear end of the vehicle, and the fixed pedal 20 is disposed on the frame body 10. The pedal assembly includes a first movable pedal 30 that is rotatably disposed on the frame body 10. The first movable pedal 30 is used to switch between an unfolded position and a folded position. The fixed pedal 20 is located above the first movable pedal 30 and is offset relative to the first movable pedal 30.

[0038] It should be noted that the rear protective device of this utility model can be installed at the rear end of a vehicle. The vehicle can be a mixer truck, a transport truck, a road work vehicle, etc. This utility model does not limit the type of vehicle to which the rear protective device is applied. This utility model embodiment is only described using a concrete mixer truck as an example.

[0039] Specifically, the frame body 10 is equipped with a first movable pedal 30 and a fixed pedal 20, which are spaced apart and staggered from bottom to top. The frame body 10 can be connected to the rear end of a vehicle. The first movable pedal 30 can swing relative to the frame body 10 to either an unfolded or folded position. When workers need to perform work at height, the first movable pedal 30 is swung relative to the frame body 10 to the unfolded position, allowing workers to step on the first movable pedal 30 and the fixed pedal 20 sequentially. The vertical spacing between the first movable pedal 30 and the fixed pedal 20 increases the climbing height, meeting the height requirements of workers performing work at height. The staggered arrangement of the fixed pedal 20 facilitates workers to step on and stand on it sequentially, improving operational safety. Furthermore, when workers do not need to perform work at height, the first movable pedal 30 can be folded relative to the frame body 10, allowing both the first movable pedal 30 and the frame body 10 to protect the rear of the vehicle. The folding of the first movable pedal 30 onto the frame body 10 increases the protective height, effectively protecting the upper structure of the vehicle's rear end and improving the protection effect. This embodiment of the rear protection device features a multi-functional integrated design, combining high protective height, good protective effect, and the ability to assist workers in performing work at height.

[0040] In this embodiment of the utility model, the pedal assembly further includes a second movable pedal 40, which is rotatably mounted on the frame body 10 and used to switch between a stepping position and a protective position. The second movable pedal 40 is located above the first movable pedal 30 and is offset relative to the first movable pedal 30. When the second movable pedal 40 is switched to the protective position, it extends upward from the upper end of the frame body 10.

[0041] like Figures 1 to 3As shown, the frame body 10 is also equipped with a second movable pedal 40, and the first movable pedal 30 and the second movable pedal 40 are spaced apart and staggered from bottom to top. The second movable pedal 40 can swing relative to the frame body 10 to a stepping position or a protective position. When workers need to perform climbing operations, the first movable pedal 30 is swung relative to the frame body 10 to the unfolded position, and the second movable pedal 40 is swung relative to the frame body 10 to the stepping position, so that workers can step on the first movable pedal 30, the second movable pedal 40 and the fixed pedal 20 in sequence, increasing the climbing height and meeting the height requirements of workers performing climbing operations. The fixed pedal 20 is fixedly installed on... The upper part of the frame body 10 has high structural strength and stable and reliable support. Workers can stand on the fixed footboard 20 to carry out operations, which improves the convenience and safety of the operation. Furthermore, when workers do not need to climb, the second movable footboard 40 can be swung relative to the frame body 10 to the protective position, and the first movable footboard 30 can be swung relative to the frame body 10 to the folded position. This allows the first movable footboard 30, the second movable footboard 40, and the frame body 10 to protect the rear end of the vehicle. Moreover, when the second movable footboard 40 is in the protective position, it extends upward and is higher than the upper part of the frame body 10, further extending the protective height and improving the protective effect and reliability.

[0042] In this embodiment of the utility model, the number of first movable pedals 30 is set to multiple, and the multiple first movable pedals 30 are vertically spaced on the frame body 10, and the multiple first movable pedals 30 are staggered along the length direction of the fixed pedal 20. Figures 1 to 3 As shown, multiple first movable pedals 30 are staggered in the left-right direction, and the second movable pedal 40 is staggered in the left-right direction from any one of the first movable pedals 30. The fixed pedal 20 is staggered in the front-back direction from the second movable pedal 40 and any one of the first movable pedals 30, so that workers can step on them sequentially from bottom to top to carry out climbing operations, which improves the convenience and safety of climbing. Furthermore, the second movable pedal 40 swings to the protective position, and multiple first movable pedals 30 swing to the folded position, which further increases the protective height and greatly improves the reliability and stability of the protection.

[0043] Furthermore, such as Figure 9 As shown, when multiple first movable pedals 30 are switched to the folded position, in any two vertically adjacent first movable pedals 30, the lower first movable pedal 30 partially blocks the upper first movable pedal 30, so that the lower first movable pedal 30 can restrict the upper first movable pedal 30 from switching to the unfolded state. This effectively prevents workers from stepping on the first movable pedals 30 across levels. The height interval setting is reasonable, further improving the safety of working at height.

[0044] In this embodiment of the invention, the first movable pedal 30, when switched to the folded position, partially obstructs the second movable pedal 40 when switched to the protective position. For example... Figure 9 As shown, when the first movable pedal 30 is switched to the folded position and the second movable pedal 40 is switched to the protective position, a first movable pedal 30 that is vertically adjacent to the second movable pedal 40 partially blocks the second movable pedal 40, thereby restricting the second movable pedal 40 from swinging from the protective position to the stepping position. This effectively prevents workers from stepping onto the second movable pedal 40 without swinging the first movable pedal 30 to the unfolded position, further improving the safety of working at height.

[0045] In this embodiment of the utility model, the frame body 10 includes a support part 11 and a protective part 12. The support part 11 is disposed on one side of the protective part 12 and is used to connect with the rear end of the vehicle. The fixed pedal 20 is connected to the protective part 12 and supported on the upper end of the support part 11. The first movable pedal 30 and the second movable pedal 40 are respectively rotatably disposed on the side of the protective part 12 facing away from the support part 11, and the second movable pedal 40 and the first movable pedal 30 are offset from each other along the length direction of the fixed pedal 20.

[0046] like Figure 3 and Figure 10 As shown, the support part 11 is connected to the protective part 12 and can be connected to the rear end of the vehicle to install the rear protective device on the vehicle. The fixed pedal 20 is connected to the protective part 12 and the support part 11 respectively, which improves the installation stability of the fixed pedal 20. The fixed pedal 20 is used for workers to stand on, thereby improving the safety of the operation. The support part 11 extends rearward from the protective part 12. The first movable pedal 30 and the second movable pedal 40 are both located on the front side of the protective part 12, so that the fixed pedal 20 supported on the support part 11 is staggered with the first movable pedal 30 and the second movable pedal 40 in the front-rear direction, and the first movable pedal 30 and the second movable pedal 40 are staggered in the left-right direction, which makes it easier for workers to step on it and improves the convenience and safety of the operation.

[0047] In this embodiment of the invention, the support portion 11 includes a connecting plate 111 and a support rod 112. The connecting plate 111 is disposed on one side of the protective portion 12 and is used to connect to the rear end of the vehicle. One end of the support rod 112 is connected to the connecting plate 111 and extends from the connecting plate 111 in a direction away from the protective portion 12. The other end of the support rod 112 is connected to the fixed pedal 20. Figure 2As shown, the connecting plate 111 is connected to the protective part 12 and the rear end of the vehicle respectively, so as to install the rear protective device on the vehicle. The assembly is convenient and quick. The two ends of the support rod 112 are connected to the connecting plate 111 and the fixed pedal 20 respectively. The support rod 112 plays the role of supporting the fixed pedal 20, improving the support stability, so that the operator can stand stably on the fixed pedal 20 to move left and right, thus improving the safety of the operation.

[0048] Furthermore, such as Figure 2 As shown, the support rod 112 includes a connecting section 1121 and a support section 1122. One end of the connecting section 1121 is connected to the connecting plate 111 and extends rearward from the connecting plate 111. The support section 1122 is connected to the other end of the connecting section 1121, and the support section 1122 is inclined rearward in a bottom-up direction so that the end of the support section 1122 away from the connecting section 1121 can be connected to the fixed pedal 20, thereby playing a role in stabilizing and supporting the fixed pedal 20, further increasing the structural strength and support stability.

[0049] In this embodiment of the utility model, the protective part 12 includes a first mounting rod 121, a second mounting rod 122, and a column 123. The first mounting rod 121 and the second mounting rod 122 are vertically spaced on the column 123. The lower end of the connecting plate 111 is connected to the first mounting rod 121, and the upper end of the connecting plate 111 is connected to the second mounting rod 122. The fixed pedal 20 is connected to the second mounting rod 122. The first movable pedal 30 is rotatably mounted on the first mounting rod 121, and the second movable pedal 40 is rotatably mounted on the second mounting rod 122.

[0050] like Figure 5 , Figure 9 and Figure 10 As shown, the column 123 is provided with a first mounting rod 121 and a second mounting rod 122 arranged at intervals from bottom to top. The first mounting rod 121 is used for hinged connection of the first movable pedal 30, and the second mounting rod 122 is used for hinged connection of the second movable pedal 40. The installation is convenient and quick. The first movable pedal 30 can be swung to a folded position relative to the first mounting rod 121, and the second movable pedal 40 can be swung to a protective position relative to the second mounting rod 122. This arrangement of the first movable pedal 30 and the second movable pedal 40 in a vertical sequence increases the protective height and improves the reliability of the protection. Furthermore, the connecting plate 111 is connected to the first mounting rod 121 and the second mounting rod 122. The connecting plate 111 is used for connection to the rear end of the vehicle. The connection strength is high, the structure is stable and reliable, and the protective effect is further improved.

[0051] Furthermore, such as Figure 3 and Figure 5As shown, a mounting plate 1221 is provided on the side of the second mounting rod 122 facing the fixed pedal 20, that is, the mounting plate 1221 is located on the rear side of the second mounting rod 122. The second movable pedal 40 is hinged to the mounting plate 1221 so that the second movable pedal 40 can swing relative to the second mounting rod 122 between the stepping position and the protective position. Since the mounting plate 1221 is located on the rear side of the second mounting rod 122 and is hinged to the second movable pedal 40, the second movable pedal 40 can be supported on the second mounting rod 122 when it swings to the stepping position. The second mounting rod 122 serves to limit the second movable pedal 40 to the stepping position, strengthens the support strength of the second movable pedal 40, and improves the stepping stability and safety.

[0052] In the embodiments of this utility model, such as Figure 7 , Figure 9 and Figure 10 As shown, the protective part 12 also includes a protective plate 124, which is connected to one side of the column 123 and supported under the fixed pedal 20. This not only improves the support strength of the fixed pedal 20, thereby improving the safety of stepping on it, but also increases the protection area of ​​the rear end of the vehicle, thus protecting the rear end of the vehicle and further improving the reliability of the protection. In addition, the protective part 12 also includes a reinforcing rod 125. The number of first mounting rods 121 is the same as the number of first movable pedals 30 and they are set one-to-one. The reinforcing rod 125 is connected between two adjacent first mounting rods 121, which strengthens the structural strength and improves the structural stability.

[0053] In this embodiment of the utility model, the rear protective device further includes a first limiting component 50, which includes a first latch 51 rotatably disposed on the fixed pedal 20, and a limiting hole 41 is provided on the second movable pedal 40. When the second movable pedal 40 is switched to the protective position, the first latch 51 extends into and engages with the limiting hole 41.

[0054] like Figure 7 and Figure 8 As shown, during the process of the second movable pedal 40 swinging towards the protective position, the first latch 51 can swing relative to the fixed pedal 20, which allows the second movable pedal 40 to push the first latch 51 to swing upward. When the first latch 51 swings to the position of the corresponding limiting hole 41, it can extend into the limiting hole 41 and swing downward under the action of gravity, thereby making the first latch 51 engage in the limiting hole 41 and limit the second movable pedal 40 to the protective position. Locking the second movable pedal 40 is simple and convenient, and effectively prevents the second movable pedal 40 from shaking during vehicle operation, ensuring the reliability of the second movable pedal 40 in protecting the rear end of the vehicle.

[0055] Furthermore, the first limiting component 50 also includes a limiting block 52, which is adjustablely disposed on the fixed pedal 20 along the width direction of the fixed pedal 20. The limiting block 52 abuts against the second movable pedal 40 when the second movable pedal 40 is switched to the protective position. Figure 7 and Figure 8 As shown, the limiting block 52 is mounted on the fixed pedal 20. When the second movable pedal 40 swings to the protective position, it abuts against the limiting block 52, thus restricting the second movable pedal 40 from swinging further backward. This helps to avoid interference with the upper structure of the concrete mixer truck, demonstrating a reasonable structural design. Furthermore, the limiting block 52 can be adjusted in the front-rear direction relative to the fixed pedal 20 to limit the second movable pedal 40 at different angles. This allows the second movable pedal 40 to avoid interference with the upper structure of different vehicle models, improving structural versatility. In addition, the first latch 51 is adjustable along the width direction of the fixed pedal 20, allowing the first latch 51 to be adjusted in the front-rear direction relative to the fixed pedal 20 in conjunction with the installation position of the limiting block 52. This provides flexible and convenient adjustment, ensuring a universal and reliable structure.

[0056] In the embodiments of this utility model, such as Figure 3 , Figure 5 and Figure 7 As shown, the fixed footboard 20 includes a footboard body 21 and a surrounding plate 22. The footboard body 21 is connected to the second mounting rod 122 and the support rod 112 respectively. The footboard body 21 is used for workers to stand on, which improves the convenience and safety of working at height. The surrounding plate 22 is arranged around the perimeter of the footboard body 21 and is used for the installation of the limiting block 52 and the first lock 51. This not only improves the convenience of installation, but also effectively prevents the limiting block 52 and the first lock 51 from interfering with the workers' work, further improving the safety of the work.

[0057] Those skilled in the art will understand that the adjustable setting of the limiting block 52 and the adjustable setting of the first latch 51 can be configured such that a waist-shaped hole extending in the front-back direction is opened on the surrounding plate 22, and the limiting block 52 and the first latch 51 can be connected to any position in the waist-shaped hole by fasteners, or it can be configured such that multiple through holes spaced apart in the front-back direction are opened on the surrounding plate 22, and the limiting block 52 and the first latch 51 can be connected to any one of the through holes by fasteners, so as to realize the adjustable setting of the limiting block 52 and the first latch 51, which is flexible and convenient to adjust and effectively prevents the second movable pedal 40 from interfering with the upper structure.

[0058] Furthermore, the plate body 21 is provided with a clearance notch for the second movable pedal 40 to extend into. The clearance notch serves to allow the second movable pedal 40 to pass through, thereby reducing the overall width and length of the rear protective device and improving the structural compactness.

[0059] In this embodiment of the utility model, the first limiting component 50 further includes a first anti-fall plate 53. The first anti-fall plate 53 includes an extension section 531 and a stop section 532. One end of the extension section 531 is connected to the frame body 10, and the stop section 532 is connected to the other end of the extension section 531 and bent toward the second movable pedal 40. The second movable pedal 40 is provided with an anti-fall hole 42. When the second movable pedal 40 is switched to the stepping position, the stop section 532 passes through the anti-fall hole 42.

[0060] like Figure 1 , Figure 3 , Figure 5 and Figure 10 As shown, the extension section 531 extends vertically, and its lower end is connected to the second mounting rod 122. The stop section 532 is connected to the upper end of the extension section 531 and extends rearward from the extension section 531. When the second movable pedal 40 swings toward the stepping position, the stop section 532 can extend into and pass through the anti-fall hole 42 on the second movable pedal 40, thereby limiting the downward swing of the second movable pedal 40. This effectively prevents the second movable pedal 40 from falling off the second mounting rod 122 in the event of hinge failure, further improving the structural stability and reliability.

[0061] In the embodiments of this utility model, such as Figures 1 to 3 As shown, the second movable pedal 40 is designed as a perforated grid plate, which can reduce the weight of the second movable pedal 40 and eliminate the need for the steps of opening the limiting hole 41 and the anti-fall hole 42. Furthermore, the first latch 51 has a first locking groove 511, which allows the ribs on the second movable pedal 40 to extend into and engage with the first locking groove 511, thereby improving the limiting stability and reliability.

[0062] In this embodiment of the utility model, the rear protective device further includes a second limiting component 60, which includes a second latch 61 and a limiting post 62. The second latch 61 is rotatably mounted on the frame body 10, and the limiting post 62 is mounted on the first movable pedal 30. When the first movable pedal 30 is switched to the folding position, the second latch 61 engages with the limiting post 62.

[0063] like Figure 5 and Figure 6As shown, during the rotation of the first movable pedal 30 toward the folded position, the second latch 61 can rotate relative to the frame body 10, causing the limiting post 62 on the first movable pedal 30 to push the second latch 61 upward. The second latch 61 has a second locking groove 611 for the limiting post 62 to extend into. When the second latch 61 rotates to the point where the limiting post 62 can extend into the second locking groove 611, it rotates downward under the action of gravity, thereby engaging with the limiting post 62 and limiting the first movable pedal 30 to the folded position. Locking the first movable pedal 30 is simple and convenient, and effectively prevents the first movable pedal 30 from shaking during vehicle operation, ensuring the reliability of the first movable pedal 30 in protecting the rear end of the vehicle. Furthermore, the first movable pedal 30 is designed as a perforated grille, reducing its weight.

[0064] In this embodiment of the utility model, the second limiting component 60 further includes a second anti-fall plate 63 and a limiting pin 64. The second anti-fall plate 63 is disposed on the frame body 10. The second anti-fall plate 63 has an anti-fall groove 631 on the side facing away from the first movable pedal 30. The first movable pedal 30 is provided with a hinge plate 31, which is hinged to the second anti-fall plate 63. The limiting pin 64 is disposed on the hinge plate 31. When the first movable pedal 30 is switched to the unfolded position, the limiting pin 64 extends into and engages in the anti-fall groove 631.

[0065] like Figure 3 and Figure 4 As shown, the second anti-fall plate 63 is mounted on the first mounting rod 121. An anti-fall groove 631 is provided on the rear side of the second anti-fall plate 63. The first movable pedal 30 is hinged to the second anti-fall plate 63 through the hinge plate 31, so that the first movable pedal 30 can drive the limiting pin 64 mounted on the first movable pedal 30 to swing and extend into the anti-fall groove 631. The limiting pin 64 extends into and engages in the anti-fall groove 631 to restrict the first movable pedal 30 from swinging downward, effectively preventing the first movable pedal 30 from falling off the first mounting rod 121 in the event of hinge failure, and further improving the structural stability and reliability.

[0066] Furthermore, such as Figures 1 to 3As shown, a limiting groove 311 is provided on the hinge plate 31. The limiting groove 311 is used for the first mounting rod 121 to extend into. The first movable pedal 30 can drive the hinge plate 31 to swing. When the first movable pedal 30 swings to the unfolded position, the first mounting rod 121 extends into and engages in the limiting groove 311. This allows the first mounting rod 121 to limit the first movable pedal 30 to the unfolded position by restricting the swing of the hinge plate 31, thereby strengthening the support strength of the first movable pedal 30 and improving the stability and safety of stepping. Furthermore, the number of first movable pedals 30 is set to be multiple, and the number of second limiting components 60 is the same as the number of first movable pedals 30 and is set one-to-one.
