[0030] The following details the embodiments of the present utility model. The embodiments described with reference to the drawings are exemplary. The following details the embodiments of the present utility model.
[0031] The following refers to Figures 1 - 4 describe an in-carriage hopper connection structure 100 according to an embodiment of the present utility model, and the present utility model also proposes a vehicle.
[0032] The in-carriage hopper connection structure 100 according to the embodiment of the present utility model includes: a vehicle frame 20, a hopper 10, and a first fastener 31. A first mounting hole 23 is provided on the vehicle frame 20. The hopper 10 is disposed above the vehicle frame 20. A second mounting hole 11 is provided on the hopper 10. The second mounting hole 11 corresponds to the first mounting hole 23. The first fastener 31 passes through the second mounting hole 11 and is fixedly connected to the first mounting hole 23. That is to say, the hopper 10 and the vehicle frame 20 are tightened at the vehicle frame 20 end, so that the structural strength of the hopper 10 will not be affected.
[0033] In addition, a cross-shaped reinforcing rib is provided on the side of the cargo bed 10 facing the vehicle frame 20, so that the structure of the connection between the cargo bed 10 and the vehicle frame 20 can be strengthened, thereby effectively improving the connection strength between the vehicle frame 20 and the cargo bed 10.
[0034] A first limiting portion 12 is provided on the inner wall of the second mounting hole 11, and a second limiting portion 331 is provided on the outer wall of the first fastener 31. The first limiting portion 12 and the second limiting portion 331 are in limiting cooperation. That is, the second limiting portion 331 on the outer wall of the first fastener 31 and the first limiting portion 12 on the inner wall of the second mounting hole 11 are in limiting cooperation, so that the circumferential limitation of the first fastener 31 can be achieved, thereby preventing the first fastener 31 from rotating after being fixed.
[0035] Thus, through the limiting cooperation between the second limiting portion 331 on the outer wall of the first fastener 31 and the first limiting portion 12 on the inner wall of the second mounting hole 11, the circumferential limitation of the first fastener 31 can be achieved, thereby preventing the first fastener 31 from rotating after being fixed.
[0036] The first limiting portion 12 is one of a limiting protrusion and a limiting groove, and the second limiting portion 331 is the other of the limiting protrusion and the limiting groove. The limiting protrusion and the limiting groove are in limiting cooperation. That is to say, the limiting cooperation between the outer wall of the first fastener 31 and the inner wall of the second mounting hole 11 is realized through the limiting protrusion and the limiting groove.
[0037] For example, the first limiting portion 12 can be a limiting groove, and the second limiting portion 331 can be a limiting protrusion. Among them, the limiting groove is a U-shaped groove. Correspondingly, the limiting protrusion includes a limiting plate located inside the U-shaped groove and two side wings respectively extending from the outer sides of the two U-shaped grooves opposite to the limiting plate. The head of the first fastener 31 passes through the limiting plate and is rotatably connected to the U-shaped groove. When the first fastener 31 rotates, the limiting plate can rotate freely in the U-shaped groove. The shape of the side wings of the limiting plate is similar to a pair of gliding wings, and it will be blocked by the two side walls of the U-shaped groove during the rotation process with the first fastener 31, so it is limited and can only rotate within a limited range.
[0038] Preferably, the limiting plate and the side wings of the limiting plate are integrally formed. Preferably, the U-shaped groove and the side wings of the U-shaped groove are integrally formed.
[0039] When the first fastener 31 and the limiting protrusion on the first fastener 31 rotate together, the side wings can only swing appropriately between the two side walls of the U-shaped groove, thereby restricting the rotation of the first fastener 31 and preventing the first fastener 31 from rotating during the fastening process.
[0040] Further, there are at least two first limiting portions 12, and the at least two first limiting portions 12 are spaced apart on the inner wall of the second mounting hole 11. There are at least two second limiting portions 331, and the at least two second limiting portions 331 are spaced apart on the outer wall of the first fastener 31. The at least two first limiting portions 12 and the at least two second limiting portions are in one-to-one limiting cooperation. With such a setting, at least two first limiting portions 12 are spaced apart on the inner wall of the second mounting hole 11, and at least two second limiting portions 331 are spaced apart on the outer wall of the first fastener 31, so that the at least two first limiting portions 12 and the at least two second limiting portions are in one-to-one limiting cooperation, thereby effectively preventing the rotation of the first fastener 31.
[0041] Among them, there are two first limiting portions 12 and two second limiting portions 331. The two first limiting portions 12 are evenly spaced on the inner wall of the second mounting hole 11. Similarly, the two second limiting portions 331 are evenly spaced on the outer wall of the first fastener 31.
[0042] Refer to Figure 4 As shown, the inner hopper connection structure 100 of the carriage further includes: a limiting member 40. The limiting member 40 is sleeved on the first fastener 31 and is located in the second mounting hole 11. The outer periphery of the limiting member 40 is in limiting cooperation with the inner wall of the second mounting hole 11.
[0043] Further, the limiting member 40 can be an elastic limiting member 40, and the diameter of the limiting member 40 is greater than or equal to the diameter of the second mounting hole 11. That is to say, the elastic limiting member 40 has the ability of elastic deformation, so that the limiting member 40 can be abutted against the inner wall of the second mounting hole 11, so that the center of the first fastener 31 is aligned with the centers of the first mounting hole 23 and the second mounting hole 11, and further, it is convenient for the first fastener 31 to connect the vehicle frame 20 and the hopper 10.
[0044] Further, since the limiting member 40 is an elastic limiting member 40, the diameter of the limiting member 40 can be set to be greater than the diameter of the second mounting hole 11, so that the limiting member 40 will deform when it is fitted in the second mounting hole 11, which can effectively improve the
[0045] Further, the limiting member 40 is a centering steel ring. The centering steel ring is sleeved on the lower part of the first fastener 31, and the contact surface between the centering steel ring and the first fastener 31 is a stamping flower-shaped tooth structure to make the contact firm.
[0046] Such as Figure 2As shown in the figure, the vehicle frame 20 includes: a vehicle frame main body 21 and a connecting bracket. The connecting bracket is arranged on the vehicle frame main body 21, and the connecting bracket and the vehicle frame main body 21 are fixedly connected. A first mounting hole 23 is arranged on the connecting bracket. That is, the vehicle frame 20 is composed of the vehicle frame main body 21 and the connecting bracket. Due to the structural limitation of the vehicle frame main body 21, the cargo box 10 and the vehicle frame main body 21 cannot be directly restricted. Therefore, a connecting bracket is provided to connect the vehicle frame main body 21 and the cargo box 10. Specifically, the connecting bracket is fixed on the vehicle frame main body 21, and the first fastener 31 is fixed on the connecting bracket, so that the cargo box 10 can be fixed on the vehicle frame main body 21.
[0047] Moreover, since there are multiple first fasteners 31, there are also multiple connecting brackets. And according to the different positions of the vehicle frame main body 21, the heights of the multiple connecting brackets can also be different, so that they can be connected between the vehicle frame main body 21 and the cargo box 10.
[0048] As Figure 3 shown in the figure, the connecting bracket includes: a first bracket 222 and a second bracket 221. The first bracket 222 is fixed above the second bracket 221, and the second bracket 221 is fixed on the vehicle frame main body 21. A second mounting hole 11 is arranged on the first bracket 222. With such a setting, the connecting bracket is composed of the first bracket 222 and the second bracket 221, so that a box-shaped structure can be formed between the first bracket 222 and the second bracket 221, thus effectively improving the strength of the connecting bracket.
[0049] As Figure 4 shown in the figure, the inner cargo box connection structure 100 further includes: a second fastener 32, and the second fastener 32 is fixedly connected to the first fastener 31. That is to say, the fixed connection between the cargo box 10 and the connecting bracket is realized through the fixed connection between the second fastener 32 and the first fastener 31, and the connection strength between the second fastener 32 and the first fastener 31 is high, which can effectively improve the connection stability between the cargo box 10 and the connecting bracket.
[0050] Furthermore, an installation space is defined between the first bracket 222 and the second bracket 221, and the second fastener 32 is located in the installation space. That is, the second fastener 32 is located in the installation space defined by the first bracket 222 and the second bracket 221, so that the second fastener 32 can be protected and prevented from being affected by foreign objects.
[0051] Among them, the second fastener 32 can be an integrally formed structure with the first bracket 222, which can effectively reduce the assembly process of the inner cargo box connection structure 100. That is, after the first fastener 31 passes through the first mounting hole 23 on the first bracket 222, it can be fixedly connected to the second fastener 32, and there is no need to additionally fix the second fastener 32 on the first fastener 31.
[0052] A receiving groove is provided on the carriage 10, and the end of the first fastener 31 is located within the receiving groove. That is, a receiving groove is provided on the carriage 10, and the end of the first fastener 31 is located within the receiving groove. Further, the upper end of the first fastener 31 does not protrude from the receiving groove, so that the first fastener 31 does not protrude relative to the inner wall of the carriage 10, thereby preventing the goods in the carriage from being knocked and scratched when sliding.
[0053] In addition, the end of the first fastener 31 can be arc-shaped. That is, the end of the first fastener 31 is set to be arc-shaped, which makes the exposed part of the first fastener 31 delicate and avoids the goods in the carriage from being knocked and scratched when sliding.
[0054] The vehicle according to the second aspect embodiment of the present invention includes a connection structure 100 between the inner hoppers of the carriage. Through the limiting cooperation between the second limiting portion 331 on the outer wall of the first fastener 31 and the first limiting portion 12 on the inner wall of the second mounting hole 11, the circumferential limiting of the first fastener 31 can be realized, thereby preventing the first fastener 31 from rotating after being fixed.
