[0032] Embodiment 1
[0033] like Figures 1 to 4 As shown, this embodiment provides a limiting mechanism 5, which is applied to a logistics vehicle and is used to limit a cargo piece 4 on the logistics vehicle to prevent the cargo piece 4 from shaking when the logistics vehicle is driving. The logistics vehicle includes a cargo piece 4, which is used to load goods. The cargo piece 4 is movably arranged on the chassis platform 200 of the logistics vehicle. The cargo piece 4 has an initial position and a working position on the chassis platform 200. The initial position is the position of the cargo piece 4 relative to the chassis platform 200 when the logistics vehicle is transporting, and the working position is the position of the cargo piece 4 relative to the chassis platform 200 when the logistics vehicle arrives at the destination and is in a state of unloading. The limiting mechanism 5 includes a limiting member 51 and a guide pin 52. The limiting member 51 is fixedly arranged on the chassis platform 200, and a limiting hole 511 is provided on the limiting member 51. The guide pin 52 is fixedly arranged on the cargo piece 4. The limiting member 51 and the guide pin 52 are arranged relative to each other. When the cargo piece 4 moves from the working position to the initial position, the guide pin 52 can be inserted into the limiting hole 511.
[0034] The guide mechanism provided in this embodiment fixes the limit member 51 on the chassis platform 200 and the guide pin 52 on the cargo part 4. When the cargo part 4 is in the transport state, the guide pin 52 is inserted into the limit hole 511. Through the cooperation of the limit member 51 and the guide pin 52, the cargo part 4 can be limited when it is in the transport state to prevent the cargo part 4 from shaking significantly, effectively solving the problem of frequent collisions between the cargo part 4 and the cargo inside it when the logistics vehicle passes through bumpy sections during transportation, thereby ensuring the aesthetics of the cargo and the use value of the cargo.
[0035] like Figure 1 and Figure 3 As shown in , in this embodiment, the cargo part 4 is movably placed on the chassis platform 200, and the logistics vehicle also includes a first driving member 1 and a connecting member 3. The first driving member 1 is fixedly arranged on the chassis platform 200 near the front end 100 of the logistics vehicle, and the output end of the first driving member 1 is connected to the connecting member 3, and the connecting member 3 is connected to the cargo part 4. In this way, by controlling the extension or retraction of the output end of the first driving member 1, it is possible to control the position of the cargo part 4 relative to the chassis platform 200, so that the cargo part 4 can be adjusted between the working position and the initial position. The first driving member 1 can use an extension cylinder, and the telescopic cylinder can be one of an electric extension cylinder, a pneumatic telescopic cylinder or a hydraulic telescopic cylinder, and no specific limitation is made here. In this embodiment, the first driving member 1 is fixed to the chassis platform 200 by bolts.
[0036] In this embodiment, Figures 3 to 5 As shown in , the guide pin 52 includes a tapered section 521, which is arranged toward the limiting hole 511. When the cargo carrier 4 is transferred from the working position to the initial position, the guide pin 52 is inserted into the limiting hole 511 through the tapered section 521. The arrangement of the tapered section 521 can guide the guide pin 52 when it is inserted into the limiting hole 511, so that the guide pin 52 can be accurately inserted into the limiting hole 511. The guide pin 52 also includes a cylindrical section 522, which is connected to the cargo carrier 4, so as to ensure the connection strength between the guide pin 52 and the cargo carrier 4 and improve the stability of the connection structure between the two. The diameter of the cylindrical section 522 is smaller than the diameter of the limiting hole 511, ensuring that after the guide pin 52 is guided into the limiting hole 511 by the conical section 521, the cylindrical section 522 can be completely inserted into the limiting hole 511, thereby increasing the degree of restriction of the limiting mechanism 5 on the cargo part 4, and further increasing the stability of the connection between the cargo part 4 and the chassis platform 200 when in the transport state.
[0037] As preferably, Figure 4 As shown in , a chamfer 5111 is circumferentially arranged at one end of the limiting hole 511 facing the conical section 521. The setting of the chamfer 5111 also guides the guide pin 52 and the limiting member 51, so that the guide pin 52 can be quickly and accurately inserted into the limiting hole 511.
[0038] In this embodiment, the limiting member 51 includes at least one first limiting member and at least one second limiting member, wherein the first limiting member is arranged close to the front of the vehicle 100, and the second limiting member is arranged away from the front of the vehicle 100. Correspondingly, the guide pin 52 includes at least one first guide pin and at least one second guide pin, wherein the first guide pin is arranged corresponding to the first limiting member, and the second guide pin is arranged corresponding to the second limiting member. In this way, the front and rear of the cargo member 4 can be restricted at the same time, further reducing the degree of shaking of the cargo member 4 when it is in the transport state, and improving the stability of the limiting mechanism 5 on the cargo member 4. Preferably, the first limiting member and the second limiting member are staggered along the width direction of the chassis platform 200, so that when the cargo member 4 is in the transport state, the degree of restriction on the cargo member 4 is more balanced, making the restriction of the cargo member 4 by the limiting mechanism 5 more stable.
[0039] Regarding the connection between the cargo part 4 and the guide pin 52, for example, on the one hand, the cargo part 4 and the guide pin 52 can be directly connected by welding to enhance the stability of the connection between the two. On the other hand, the guide pin 52 can also be connected to the cargo part 4 through the connecting bracket 6. For the irregular area in the cargo part 4, it is inconvenient to directly install the guide pin 52. In this case, the two can be connected through the connecting bracket 6. The shape of the connecting bracket 6 can be selected according to the structure of the cargo part 4 to improve the flexibility of the connection method between the guide pin 52 and the cargo part 4. The selection of the connection method between the cargo part 4 and the guide pin 52 is not shown here. The cross-sectional shape of the connecting bracket 6 can be a triangle, a rectangle, a circle or an irregular shape, which can be selected according to the structure of the cargo part 4, and no specific limitation is made here.
[0040] In this embodiment, the limiting member 51 includes a fixing seat 512 and a reinforcing rib 513, wherein the fixing seat 512 includes a long plate and a short plate perpendicular to each other, the short plate is fixed to the chassis platform 200, and the limiting hole 511 is set on the long plate, so that when the guide pin 52 is fully inserted into the limiting hole 511, that is, when the cargo member 4 is in the transport state, the cargo member 4 and the long plate are in a fit state, which can further limit the shaking of the cargo member 4. The reinforcing rib 513 is connected to the long plate and the short plate, and the setting of the reinforcing rib 513 can improve the stability of the overall structure of the limiting member 51, and further reduce the shaking degree of the cargo member 4 in the transport state.
[0041] In order to make the use of the cargo carrier 4 more flexible, in this embodiment, the logistics vehicle further includes a second driving member 2, wherein the second driving member 2 is fixedly connected to the connecting member 3 and is arranged at an acute angle to the surface of the chassis platform 200, and the output end of the second driving member 2 is connected to the cargo carrier 4. The connecting member 3 is divided into a proximal end close to the vehicle head 100 and a distal end away from the vehicle head 100, and the cargo carrier 4 is rotatably connected to the distal end of the vehicle head 100, so that when the output end of the first driving member 1 is extended, the connecting member 3, the second driving member 2 and the cargo carrier 4 move together along the extension direction of the output end of the first driving member 1, and the cargo carrier 4 is in the working position, and then the second driving member 2 is started to extend the output end of the second driving member 2. Since the distal end of the connecting member 3 is rotatably connected to the cargo carrier 4, as the second driving member 2 is extended, the cargo carrier 4 gradually rotates until it is perpendicular to the chassis platform 200. At the same time, when the output ends of the second driving member 2 and the second driving member 2 are retracted in sequence, the cargo carrier 4 will be adjusted to the transportation state. The second driving member 2 is provided to enable the cargo carrying member 4 to perform a flipping motion, thereby making the cargo carrying member 4 more flexible to use. The second driving member 2 may also be a telescopic cylinder, which may be an electric extension cylinder, a pneumatic telescopic cylinder, or a hydraulic telescopic cylinder, and is not specifically limited here. The second driving member 2 in this embodiment may be fixedly connected to the connecting member 3 by bolts.
[0042] Preferably, the logistics vehicle further includes a guide groove 7, which is laid on the side of the limiting member 51 away from the vehicle head 100, that is, the guide groove 7 is laid in front of the limiting member 51, wherein the direction of the guide groove 7 is consistent with the extension direction of the first driving member 1, and at the same time, a roller 41 is provided on the bottom surface of the cargo carrying member 4, and when the output end of the first driving member 1 is extended or retracted, the roller 41 will move along the guide groove 7. The arrangement of the roller 41 and the guide groove 7 can ensure that when the first driving member 1 drives the cargo carrying member 4 to move through the connecting member 3, the cargo carrying member 4 can stably move with the extension and retraction of the first driving member 1, and the guide groove 7 also guides the movement of the cargo carrying member 4, ensuring that the movement direction of the cargo carrying member 4 is correct and avoiding the problem of deviation of the cargo carrying member 4 when moving.
[0043] In this embodiment, the logistics vehicle further includes a guide rail 8 and a slider, wherein the guide rail 8 is laid on the chassis platform 200 along the extension direction of the first driving member 1, and the slider is slidably arranged on the guide rail 8, and the slider is connected to the connecting member 3. When the output end of the first driving member 1 is extended or retracted, the connecting member 3 acts along the direction of the guide rail 8. For a heavy cargo member 4, the setting of the guide rail 8 can prevent the cargo member 4 from deflecting when the output end of the first driving member 1 is telescopic, thereby improving the stability of the cargo member 4 when moving. Preferably, two guide rails 8 are laid in parallel, and each guide rail 8 is provided with a slider, and both sliders are connected to the connecting member 3, further improving the stability of the cargo member 4 during movement.
[0044] Regarding the connection between the connecting member 3 and the cargo carrying member 4, on the one hand, the two are connected by a latch or a pin, and at the same time, the two can rotate relative to each other, so that the two are connected in a rotational manner. The above connection method is a conventional connection method in the mechanical field and does not belong to the key protection content of the utility model.
[0045] On the other hand, the connecting member 3 and the cargo carrying member 4 can also be rotationally connected by the cooperation of multiple parts. In this embodiment, the connecting member 3 and the rotating member are rotationally connected by the cooperation of multiple parts. The logistics vehicle also includes a mounting member, which includes a connecting frame and a connecting rod. The connecting frame is fixedly arranged at the far end of the connecting member 3, and a through hole is provided on the connecting frame. The cargo carrying member 4 has a mounting portion, and the mounting portion has a mounting hole. The connecting rod penetrates and connects the through hole and the mounting hole, so that the cargo carrying member 4 can rotate relative to the connecting member 3. Preferably, the mounting member also includes a bearing, a support seat and a limiting member. The support seat is located on the side of the cargo carrying member 4, and the support seat has a side guide groove with an opening facing the cargo carrying member 4. The bearing is placed in the side guide groove. The connecting rod is connected to the inner ring of the bearing after passing through the through hole and the mounting hole. The limiting member is placed on the connecting rod and always abuts against the end face of the bearing. When the output end of the second driving member 2 is retracted, the connecting rod will rotate. The setting of the bearing can improve the smoothness of the connecting rod when rotating. At the same time, the support seat can support the corners of the cargo carrier 4, thereby improving the stability of the cargo carrier 4 when rotating. The limiting member is always in contact with the end face of the bearing, which can prevent the inner ring of the bearing from moving when rotating, and ensure the stability of the shelf during rotation. Exemplarily, the limiting member includes a limiting plate and a clamp, wherein the limiting plate and the clamp are both sleeved on the connecting rod, the limiting plate abuts against the end face of the bearing, and the clamp abuts against the end face of the limiting plate, so that the limiting member is always in contact with the end face of the bearing.
[0046] Embodiment 2
[0047] This embodiment provides a logistics vehicle, including the limiting mechanism 5 in the first embodiment, and the logistics vehicle also includes a cargo carrying part 4 and a first driving member 1, wherein the output end of the first driving member 1 is connected to the cargo carrying part 4, and the limiting mechanism 5 is used to limit the cargo carrying part 4 in the initial position. The logistics vehicle provided by this embodiment can ensure that the cargo carrying part 4 will not shake significantly when passing through a bumpy road section, thereby ensuring the use of the cargo carrying part 4 and the cargo therein.
[0048] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention.
