Description

Technical Field

[0001] This invention belongs to the field of electric bus technology, and relates to a front frame trailer structure and a bus. Background Technology

[0002] When towing or securing a vehicle, a tow hook is required. The front tow hook of a traditional bus is usually installed in front of the first crossbeam and connected to the web of the first crossbeam via a bracket, or it is installed on the web of the left and right longitudinal beams of the frame.

[0003] In existing technologies, trailer hitches are often made by directly welding a single trailer hitch with a trailer hitch to the vehicle frame. This connection method is simple and crude, but unreliable. It is still prone to falling off and damage, and it is difficult to meet the safety towing force requirements of some medium and large buses. There is considerable room for improvement. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a front frame trailer structure and a bus.

[0005] The objective of this invention can be achieved through the following technical solution: a front frame trailer structure, comprising:

[0006] The frame has vertically distributed mounting plates;

[0007] The trailer seat has a square column structure, one end of which is connected to the mounting plate, and the other end of which is provided with a trailer hook;

[0008] The first reinforcing rib includes a reinforcing top plate and two reinforcing side plates. The two reinforcing side plates are respectively disposed on both sides of the reinforcing top plate and the reinforcing top plate and the two reinforcing side plates are integrally formed. The reinforcing top plate is connected to the upper part of the trailer seat, and the two reinforcing side plates are respectively connected to the two sides of the trailer seat. The reinforcing top plate and the two reinforcing side plates are both connected to the mounting plate.

[0009] In the aforementioned front frame trailer structure, a second reinforcing rib is also included. The upper part of the frame extends beyond the mounting plate to form a first connecting part. The second reinforcing rib includes a connecting top plate, a connecting side plate, and a connecting bottom plate. The connecting top plate, the connecting side plate, and the connecting bottom plate are connected sequentially from top to bottom and integrally formed. The connecting top plate is connected to the first connecting part, the connecting bottom plate is connected to the reinforcing top plate, and the connecting top plate, the connecting bottom plate, and the connecting side plate are all connected to the mounting plate.

[0010] In the aforementioned front frame trailer structure, the length of the connecting bottom plate along the trailer hook axis is greater than the length of the connecting top plate along the trailer hook axis, and the length of the connecting side plate along the trailer hook axis changes from short to long from top to bottom.

[0011] In the aforementioned front frame trailer structure, a third reinforcing rib is also included. The mounting plate extends beyond the bottom of the frame and bends inward toward the frame to form a second connecting part. The third reinforcing rib includes a supporting bottom plate, a supporting web plate, and a supporting top plate. The supporting bottom plate, the supporting web plate, and the supporting top plate are connected sequentially from bottom to top and integrally formed. The supporting bottom plate is connected to the second connecting part, and the supporting top plate is connected to the lower part of the two reinforcing side plates.

[0012] In the aforementioned front frame trailer structure, the length of the reinforcing side plate gradually increases from the middle to the end away from the trailer hook in the vertical direction and forms an arc-shaped surface. The supporting web plate is connected to the arc-shaped surface plate, and the shape of the supporting web plate is adapted to the arc-shaped surface plate.

[0013] In the aforementioned front frame trailer structure, a side reinforcement assembly is also included. The side reinforcement assembly includes a reinforcing crossbeam and a reinforcing longitudinal beam. One end of the reinforcing crossbeam is connected to the trailer seat, and the other end of the reinforcing crossbeam is connected to one end of the reinforcing longitudinal beam. The reinforcing longitudinal beam is parallel to the trailer seat, and the other end of the reinforcing longitudinal beam is connected to the frame.

[0014] In the aforementioned front frame trailer structure, the connecting side plate is the reinforcing side plate on the side close to the first reinforcing rib, and the reinforcing crossbeam is connected to the reinforcing side plate on the other side of the first reinforcing rib.

[0015] In the aforementioned front frame trailer structure, the side reinforcement assembly further includes a first reinforcing diagonal beam and a second reinforcing diagonal beam. One end of the first reinforcing diagonal beam is connected to the reinforcing crossbeam, and the connection point is located directly below the connection point between the reinforcing longitudinal beam and the frame. One end of the second reinforcing diagonal beam is connected to the reinforcing crossbeam, and the connection point is located diagonally below the connection point between the reinforcing longitudinal beam and the frame.

[0016] In the aforementioned front frame trailer structure, the trailer seat is provided with an internal thread, and the trailer hook is provided with an external thread. The trailer hook is connected to the internal thread of the trailer seat through the external thread, thereby making the trailer hook and the trailer seat detachably connected.

[0017] Secondly, a passenger vehicle including the aforementioned front frame trailer structure.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. The semi-enclosed structure formed by the reinforced top plate and two reinforced side plates increases the strength of the trailer seat when subjected to front and rear tension and compression, and at the same time can play a certain role in protecting the trailer seat, preventing other objects from directly colliding with the trailer seat from above or the side.

[0020] 2. The first reinforcing rib is connected to the first connecting part formed by the extension of the upper part of the frame by the second reinforcing rib, which increases the strength of the trailer seat when subjected to front and rear tension and compression and up and down swing. It can also play a pulling role on the trailer seat and distribute the weight of the trailer seat itself. Even when the connection area between the connecting top plate and the first connecting part is small, the connection area between the connecting bottom plate and the reinforcing top plate is still large, thereby reducing the pressure between the two.

[0021] 3. The first reinforcing rib is connected to the second connecting part formed by bending the bottom of the frame by the third reinforcing rib, which increases the strength of the trailer seat when subjected to front and rear tension and compression as well as up and down swing. It can also support the trailer seat, distribute the weight of the trailer seat itself, and increase the contact area between the two by the arc surface, thereby reducing the pressure between the two and greatly improving the support capacity of the third reinforcing rib.

[0022] 4. The first reinforcing rib is connected to the part of the frame adjacent to the mounting plate by the side reinforcing assembly, which increases the strength of the trailer seat when subjected to front and rear tension and compression as well as left and right swing. The reinforcing side plate is connected to the side plate near the first reinforcing rib, while the reinforcing crossbeam is connected to the reinforcing side plate on the other side of the first reinforcing rib. The overall structure is lightweight while ensuring balanced stress strength on both sides.

[0023] 5. The additional first reinforcing beam increases the strength of the trailer seat when subjected to front-to-back tension and compression, as well as up-and-down swinging, and can also support the trailer seat and distribute its own weight. The additional second reinforcing beam increases the strength of the trailer seat when subjected to front-to-back tension and compression, left-to-right swinging, as well as up-and-down swinging, and can also support the trailer seat and distribute its own weight.

[0024] 6. The trailer hook is connected to the trailer seat via an external thread, making the trailer hook and trailer seat detachable and thus meeting the need for easy disassembly and storage of the trailer hook. Attached Figure Description

[0042] like Figures 1-10 As shown, a front frame trailer structure includes: a frame 100, a trailer seat 200, and a first reinforcing rib 300.

[0043] The frame 100 is provided with vertically distributed mounting plates 110.

[0044] The trailer seat 200 has a square column structure. One end of the trailer seat 200 is connected to the mounting plate 110, and the other end of the trailer seat 200 is provided with a trailer hook 210.

[0045] The first reinforcing rib 300 includes a reinforcing top plate 310 and two reinforcing side plates 320. The two reinforcing side plates 320 are respectively disposed on both sides of the reinforcing top plate 310 and the reinforcing top plate 310 and the two reinforcing side plates 320 are integrally formed. The reinforcing top plate 310 is connected to the upper part of the trailer seat 200, and the two reinforcing side plates 320 are respectively connected to the two sides of the trailer seat 200. The reinforcing top plate 310 and the two reinforcing side plates 320 are all connected to the mounting plate 110.

[0046] In this embodiment, the semi-enclosed structure formed by the reinforced top plate 310 and the two reinforced side plates 320 increases the strength of the trailer seat 200 when subjected to front and rear tension and compression, which can meet the safety towing tension (compression) requirement of at least 19 tons, and at the same time can play a certain protective role for the trailer seat 200, preventing other objects from directly colliding with the trailer seat 200 from above or the side.

[0047] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, based on the above embodiment, a second reinforcing rib 400 is also included. The upper part of the frame 100 extends beyond the mounting plate 110 to form a first connecting portion 120. The second reinforcing rib 400 includes a connecting top plate 410, a connecting side plate 420, and a connecting bottom plate 430. The connecting top plate 410, the connecting side plate 420, and the connecting bottom plate 430 are connected sequentially from top to bottom and integrally formed. The connecting top plate 410 is connected to the first connecting portion 120, and the connecting bottom plate 430 is connected to the reinforcing top plate 310. The connecting top plate 410, the connecting bottom plate 430, and the connecting side plate 420 are all connected to the mounting plate 110.

[0048] In this embodiment, the first reinforcing rib 300 is connected to the first connecting part 120 extending from the upper part of the frame 100 by the second reinforcing rib 400, which increases the strength of the trailer seat 200 when subjected to front-to-back tension and compression as well as up-and-down swinging, and can also play a pulling role on the trailer seat 200, distributing the weight of the trailer seat 200 itself.

[0049] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8As shown, based on the above embodiment, the length of the connecting bottom plate 430 along the axis of the trailer hook 210 is greater than the length of the connecting top plate 410 along the axis of the trailer hook 210, and the length of the connecting side plate 420 along the axis of the trailer hook 210 changes from short to long from top to bottom.

[0050] In this embodiment, when the connection area between the connecting top plate 410 and the first connecting part 120 is small, the length of the connecting bottom plate 430 along the axis of the trailer hook 210 is greater than the length of the connecting top plate 410, and the length of the connecting side plate 420 in this direction changes from short to long from top to bottom, so as to maintain a large connection area between the connecting bottom plate 430 and the reinforcing top plate 310 and reduce the pressure between them.

[0051] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 As shown, based on the above embodiment, a third reinforcing rib 500 is also included. The mounting plate 110 extends beyond the bottom of the frame 100 and bends inward toward the frame 100 to form a second connecting portion 111. The third reinforcing rib 500 includes a supporting bottom plate 510, a supporting web plate 520, and a supporting top plate 530. The supporting bottom plate 510, the supporting web plate 520, and the supporting top plate 530 are connected sequentially from bottom to top and integrally formed. The supporting bottom plate 510 is connected to the second connecting portion 111, and the supporting top plate 530 is connected to the lower part of the two reinforcing side plates 320.

[0052] In this embodiment, the first reinforcing rib 300 is connected to the second connecting part 111 formed by bending the bottom of the frame 100 by the third reinforcing rib 500, which increases the strength of the trailer seat 200 when subjected to front and rear tension and compression and up and down swing, and can also support the trailer seat 200 and distribute the weight of the trailer seat 200 itself.

[0053] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 As shown, based on the above embodiment, the length of the reinforcing side plate 320 gradually increases from the middle to the end away from the trailer hook 210 in the vertical direction and forms an arc-shaped surface 321. The supporting web plate 520 is connected to the arc-shaped surface 321 and the shape of the supporting web plate 520 is adapted to the arc-shaped surface 321.

[0054] In this embodiment, the reinforcing side plate 320 is formed with an arc-shaped surface 321, and the supporting web plate 520 is connected to the arc-shaped surface 321. The shape of the supporting web plate 520 is adapted to the arc-shaped surface 321, connecting the reinforcing side plate 320 and the supporting web plate 520 together and increasing the contact area between the two through the arc surface, thereby reducing the pressure between the two and greatly improving the supporting capacity of the third reinforcing rib 500.

[0055] Furthermore, it is worth noting that the curved surface 321 of the reinforced side plate 320 can play a certain role in flexible connection. Even if the trailer seat 200 and the first reinforcing rib 300 are separated from the frame 100, they can still maintain a flexible connection through the third reinforcing rib 500.

[0056] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 As shown, based on the above embodiment, a side reinforcement assembly 600 is also included. The side reinforcement assembly 600 includes a reinforcing crossbeam 610 and a reinforcing longitudinal beam 620. One end of the reinforcing crossbeam 610 is connected to the trailer seat 200, and the other end of the reinforcing crossbeam 610 is connected to one end of the reinforcing longitudinal beam 620. The reinforcing longitudinal beam 620 is parallel to the trailer seat 200, and the other end of the reinforcing longitudinal beam 620 is connected to the vehicle frame 100.

[0057] In this embodiment, the first reinforcing rib 300 is connected to the part of the frame 100 adjacent to the mounting plate 110 by the side reinforcing component 600, which increases the strength of the trailer seat 200 when subjected to front-to-back tension and compression as well as left-to-right swing.

[0058] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, based on the above embodiment, the connecting side plate 420 is the reinforcing side plate 320 on the side close to the first reinforcing rib 300, and the reinforcing beam 610 is connected to the reinforcing side plate 320 on the other side of the first reinforcing rib 300.

[0059] In this embodiment, the reinforcing side plate 320 of the connecting side plate 420 is close to the side of the first reinforcing rib 300, while the reinforcing crossbeam 610 is connected to the reinforcing side plate 320 on the other side of the first reinforcing rib 300, thereby achieving a lightweight overall structure while ensuring balanced stress strength on both sides.

[0060] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 As shown, based on the above embodiment, the side reinforcement assembly 600 further includes a first reinforcing diagonal beam 630 and a second reinforcing diagonal beam 640. One end of the first reinforcing diagonal beam 630 is connected to the reinforcing crossbeam 610, and one end of the first reinforcing diagonal beam 630 is connected to the frame 100, with the connection point located directly below the connection point between the reinforcing longitudinal beam 620 and the frame 100. One end of the second reinforcing diagonal beam 640 is connected to the reinforcing crossbeam 610, and one end of the second reinforcing diagonal beam 640 is connected to the frame 100, with the connection point located obliquely below the connection point between the reinforcing longitudinal beam 620 and the frame 100.

[0061] In this embodiment, the additionally provided first reinforcing inclined beam 630 increases the strength of the trailer seat 200 when subjected to front-to-back tension and compression, as well as up-and-down swinging, and can also support the trailer seat 200 and distribute its own weight; the additionally provided second reinforcing inclined beam 640 increases the strength of the trailer seat 200 when subjected to front-to-back tension and compression, left-to-right swinging, as well as up-and-down swinging, and can also support the trailer seat 200 and distribute its own weight.

[0062] like Figure 5 , Figure 6 As shown, based on the above embodiment, the trailer seat 200 is provided with an internal thread 220, and the trailer hook 210 is provided with an external thread 211. The trailer hook 210 is connected to the internal thread 220 of the trailer seat 200 through the external thread 211, thereby making the trailer hook 210 detachably connected to the trailer seat 200.

[0063] In this embodiment, the trailer hook 210 is connected to the trailer seat 200 via the external thread 211 and the internal thread 220, thereby making the trailer hook 210 and the trailer seat 200 detachably connected, thus fulfilling the need for easy disassembly and storage of the trailer hook 210.
