Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a vehicle and a shock-absorbing frame. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, the environmental pollution caused by emissions from traditional gasoline-powered vehicles is becoming increasingly serious, prompting a shift in energy structure towards cleaner and lower-carbon energy sources. LNG, as a clean and efficient energy source, is increasingly being used in the transportation sector, leading to a growing demand for LNG storage and transportation equipment. However, traditional vehicle frames are relatively rigid, and the torsional stress generated during vehicle operation is directly transferred to the frame through the chassis. After prolonged vehicle operation, the frame and the system components mounted on it may crack, break, or become damaged. Summary of the Invention

[0003] The purpose of this invention is to provide a shock-absorbing frame and a vehicle having the shock-absorbing frame, so as to solve the problems in the prior art.

[0004] To address the aforementioned technical problems, the present invention provides a shock-absorbing frame, comprising at least two supports spaced parallel to each other in the transverse direction; each support includes: Sub-beams, which extend longitudinally and are used to connect to the chassis; A connector for attaching to the bottom of the gas cylinder; Two bent components are spaced apart along the longitudinal direction; the top of the bent components is fixedly connected to the connector and together they enclose a receiving space. Two support columns are provided, corresponding one-to-one with the two bending components; the lower part of the support column is connected to the sub-beam, and the upper part extends into the corresponding receiving space and is screwed to the bending component. Two elastic elements are provided, corresponding one-to-one with the two support columns; the elastic elements are sleeved on the outer periphery of the corresponding support columns and located between the bending element and the sub-beam.

[0005] In one embodiment, an upper positioning ring is fitted around the top outer periphery of the elastic member and is fixed to the bottom of the bent member; a lower positioning ring is fitted around the bottom outer periphery of the elastic member and is fixed to the top of the sub-beam.

[0006] In one embodiment, the elastic element is a spring.

[0007] In one embodiment, the connector includes multiple arc-shaped plates spaced apart, the multiple arc-shaped plates being located on the same circumference and symmetrically arranged about the axis of the gas cylinder, and the arc-shaped plates being attached to the bottom of the gas cylinder; The support column is bolted to the sub-beam.

[0008] In one embodiment, the bracket includes a plurality of limiting members spaced apart between the two support columns. The limiting members are connected between the connector and the sub-beam and are used to restrict the movement of the connector and the sub-beam in the lateral and longitudinal directions.

[0009] In one embodiment, the limiting member includes a limiting ring and a limiting post. One of the limiting ring and the limiting post is fixed to the top of the sub-beam, and the other is fixed to the bottom of the connector. The limiting ring is sleeved on the outer periphery of the limiting post, and there is a gap between the two.

[0010] In one embodiment, the limiting ring is provided with a limiting hole that extends through the top and bottom. The limiting hole has a circular outline, and the limiting post has a circular cross-section. The difference between the diameter of the limiting hole and the outer diameter of the limiting post is 2~5mm.

[0011] In one embodiment, the bending member includes a first side plate and a second side plate arranged in parallel and spaced apart, and a bottom plate connecting the first side plate and the second side plate. The first side plate and the second side plate extend vertically, and the bottom plate extends longitudinally. The first side plate is located outside the second side plate and extends upward beyond the second side plate. The bottom plate is provided with a threaded hole that runs vertically through the bottom plate.

[0012] In one embodiment, the shock-absorbing frame includes a mounting bracket connecting two of the supports, the two supports being longitudinally spaced apart, and the mounting bracket extending laterally for mounting a buffer tank.

[0013] In one embodiment, the sub-beam includes a horizontally extending upper flange and a lower flange, and a transition plate connecting the upper flange and the lower flange. The transition plate extends vertically. The upper flange has a through-hole, and the peripheral sidewall of the through-hole is threaded. The support column passes through the through-hole from the bottom of the upper flange and is screwed in. The mounting bracket of the shock-absorbing frame is connected to the lower wing plate.

[0014] The present invention also provides a vehicle, including a frame, a gas cylinder, and a shock-absorbing frame as described above, wherein the shock-absorbing frame is mounted on the frame, the gas cylinder is mounted on the shock-absorbing frame, and the two brackets are spaced apart along the axial direction of the gas cylinder.

[0015] In one embodiment, the gas cylinder is fixedly connected to the connecting member; The gas cylinder is welded to the connector.

[0016] As can be seen from the above technical solution, the advantages and positive effects of the present invention are as follows: The shock-absorbing frame in this application connects the gas cylinder and the vehicle frame, reducing the vibration transmitted from the vehicle frame to the gas cylinder, reducing or even eliminating the stress transmitted from the vehicle frame to the gas cylinder, thereby avoiding damage to the gas cylinder and ensuring safe use. The damping frame includes at least two supports spaced parallel to each other in the transverse direction. Each support includes a sub-beam, a connector, two bent parts, two support columns, and two elastic elements. Compared to damping frames in related technologies, this design eliminates structures such as the upper crossbeam and tension sleeve, reducing the overall weight of the damping frame and thus lowering costs.

[0021] Although the invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the invention and is not intended to limit the invention to what is described herein.

[0022] Therefore, a feature pointed out in this specification is used to illustrate one feature of one embodiment of the invention, and does not imply that every embodiment of the invention must have the described feature. Furthermore, it should be noted that this specification describes many features. While certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0023] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of the invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0024] This application provides a vehicle including a frame, a gas cylinder, and a shock absorber frame, wherein the shock absorber frame is mounted on the frame and the gas cylinder is mounted on the shock absorber frame.

[0025] For ease of description, the length direction of the frame is defined as longitudinal, and the width direction as transverse.

[0026] The gas cylinders are arranged axially along a transverse direction. Each cylinder contains fuel used to power the vehicle. The fuel can be a clean energy source such as LNG or CNG.

[0027] The shock-absorbing frame connects the gas cylinder and the vehicle frame. Through its own flexibility, the shock-absorbing frame acts as a buffer, reducing or even eliminating the stress transmitted from the vehicle frame. It also serves as an intermediate medium between the vehicle frame and the gas cylinder to reduce the vibration transmitted from the vehicle frame to the gas cylinder, thereby reducing or even eliminating the stress transmitted from the vehicle frame to the gas cylinder, thus preventing damage to the gas cylinder and ensuring safe use. Compared to traditional frames in related technologies, the elimination of structures such as the upper crossbeam and tie sleeve reduces the weight of the entire shock-absorbing frame, thereby lowering costs.

[0028] Combination Figures 1-3 The shock-absorbing frame 1 includes at least two supports 11 arranged laterally and parallel to each other. The at least two supports 11 are arranged axially and spaced apart along the gas cylinder 2, thereby supporting the entire gas cylinder 2.

[0029] The number of supports 11 can be two, three, or other numbers, depending on the actual needs. In this embodiment, two supports 11 are used as an example.

[0030] The two supports 11 are preferably arranged symmetrically about the axial center of the gas cylinder 2. This can also be understood as the two supports 11 being symmetrically arranged about the vertical central axis of the gas cylinder 2. Here, the vertical central axis of the gas cylinder 2 refers to the plane that passes through the axis of the gas cylinder 2 and extends vertically.

[0031] When the number of supports 11 is odd, one of the supports 11 is the central support 11, which is located at the axial center of the gas cylinder 2, and the other supports 11 are symmetrically arranged about the central support 11. When the number of supports 11 is even, the multiple supports 11 are symmetrically arranged about the axial center of the cylinder.

[0032] Specifically, each support 11 includes a sub-beam 111, a connector, two bent parts 113, two support columns 114, and two elastic parts 115.

[0033] The sub-beam 111 extends longitudinally and is used to connect to the frame. The sub-beam 111 is perpendicular to the axial direction of the gas cylinder 2.

[0034] The sub-beam 111 includes a horizontally extending upper flange 1111 and a lower flange 1112, as well as a transition plate 1113 connecting the upper flange 1111 and the lower flange 1112. The transition plate 1113 extends vertically, and the upper flange 1111 has a through-hole.

[0035] The upper wing plate 1111, the lower wing plate 1112 and the transition plate 1113 enclose an opening, and the openings of the secondary beams 111 of the two supports 11 are arranged opposite to each other.

[0036] The sub-beam 111 is preferably provided with weight-reducing holes to reduce its weight. Specifically, the weight-reducing holes are provided on the transition plate 1113.

[0037] The sub-beam 111 is detachably connected to the main beam on the vehicle frame. The detachable connection method between the sub-beam 111 and the main beam can refer to relevant technologies, and this application does not make any improvements thereto.

[0038] The detachable connection between the sub-beam 111 and the main beam allows for replacement according to vehicle model, thus adapting to various vehicle types and improving the versatility of the entire shock absorber frame 1. Specifically, the sub-beam 111 is bolted to the support column 114. This bolted connection not only enables a detachable connection between the sub-beam 111 and the support column 114 but also provides better resistance to the impact of vibrations.

[0039] The connector is used to connect to the bottom of the gas cylinder 2. Specifically, the connector is fixedly connected to the gas cylinder 2. In this embodiment, the connector is welded to the gas cylinder 2.

[0040] The connector includes multiple arc-shaped plates 1121 spaced apart. These arc-shaped plates 1121 are located on the same circumference and symmetrically arranged about the axis of the gas cylinder 2. The dimensions of the arc-shaped plates 1121 can be identical or different, depending on actual needs. In practical applications, arc-shaped plates 1121 are ensured to be provided at corresponding bending parts 113 and corresponding limiting parts.

[0041] Each arc-shaped plate 1121 is attached to the bottom of the gas cylinder 2. That is, the shape of the arc-shaped plate 1121 is adapted to the shape of the gas cylinder 2.

[0042] By setting the connector as a multi-segment arc plate 1121 with intervals, the weight of the connector is reduced, the amount of material used in the connector is reduced, and thus the cost is reduced.

[0043] Two bent pieces 113 are arranged longitudinally at intervals, that is, the two bent pieces 113 are arranged on opposite sides of the gas cylinder 2. The top of the bent pieces 113 are fixedly connected to the connector and together they enclose a receiving space.

[0044] The bent component 113 includes a first side plate 1131 and a second side plate 1132 arranged in parallel intervals, and a bottom plate 1133 connecting the first side plate 1131 and the second side plate 1132. The first side plate 1131 and the second side plate 1132 extend vertically, and the bottom plate 1133 extends longitudinally. The first side plate 1131 is located outside the second side plate 1132, and the first side plate 1131 extends upward beyond the second side plate 1132. The bottom plate 1133 connects the bottom of the first side plate 1131 and the bottom of the second side plate 1132. The first side plate 1131, the second side plate 1132, and the bottom plate 1133 enclose a U-shaped structure. Here, "outer" and "inner" are used with reference to the usage state of the shock-absorbing frame 1, where the direction in which one bent component 113 is closer to another bent component 113 is "inner," and vice versa.

[0045] The base plate 1133 has a through hole running vertically through it. This through hole is used for the support column 114 to pass through.

[0046] Two support columns 114 are provided in a one-to-one correspondence with two bent parts 113. The lower part of the support column 114 is screwed to the sub-beam 111, and the upper part extends into the corresponding receiving space and is screwed to the bent part 113.

[0047] The support column 114 has external threads on its outer periphery, allowing it to be screwed onto the bent member 113 and the sub-beam 111. Specifically, the support column 114 includes a bolt 1141 and a nut 1142. The bolt 1141 includes a threaded rod and a nut located at one end of the threaded rod. The threaded rod has external threads on its outer periphery, and the nut 1142 can be screwed onto the threaded rod. The threaded rod can be screwed onto the bent member 113 and the sub-beam 111.

[0048] The support column 114 passes through the connecting hole from the bottom of the upper flange 1111 and is screwed in, thereby realizing the connection between the support column 114 and the sub-beam 111.

[0049] In this embodiment, bolt 1141 is a high-strength bolt 1141.

[0050] Two elastic elements 115 are correspondingly installed with two support columns 114. The elastic elements 115 are sleeved on the outer periphery of the corresponding support column 114 and are located between the bent part 113 and the sub-beam 111. The elasticity of the elastic elements 115 achieves vertical limitation of the support column 114.

[0051] In this configuration, after the support column 114 is connected to the bending member 113 and the sub-beam 111, the elastic member 115 is in a compressed state. Preferably, the elastic member 115 is in a slightly compressed state.

[0052] When vibrations occur during vehicle operation, the elastic element 115 can further compress or recover to buffer the stress transmitted to the gas cylinder 2, thereby reducing or even offsetting the stress.

[0053] Furthermore, an upper positioning ring 116 is fitted around the top outer periphery of the elastic member 115, and the upper positioning ring 116 is fixed to the bottom of the bent member 113. A lower positioning ring 117 is fitted around the bottom outer periphery of the elastic member 115, and the lower positioning ring 117 is fixed to the top of the sub-beam 111.

[0054] The positioning effect of the upper positioning ring 116 and the lower positioning ring 117 on the elastic element 115 prevents the elastic element 115 from bending or shifting, and ensures the extension and retraction direction of the elastic element 115.

[0055] In this embodiment, the elastic element 115 is a spring.

[0056] Furthermore, the bracket 11 includes a plurality of limiting members spaced apart between the two support columns 114. That is, the plurality of limiting members are spaced apart along the longitudinal direction. Each limiting member is connected between the connector and the sub-beam 111 and is used to restrict the movement between the connector and the sub-beam 111 in the lateral and longitudinal directions.

[0057] In this embodiment, there are two limiting members. In other embodiments, the number can be set according to actual needs.

[0058] Multiple limiting components are symmetrically arranged about the center of the gas cylinder between the two support columns 114. This can also be understood as multiple limiting components being symmetrically arranged about the vertical central axis of the gas cylinder 2.

[0059] Specifically, the limiting component includes a limiting ring 118 and a limiting post 119. One of the limiting ring 118 and the limiting post 119 is fixed to the top of the sub-beam 111, and the other is fixed to the bottom of the connecting member. The limiting ring 118 is sleeved on the outer periphery of the limiting post 119, and there is a gap between the two. In this embodiment, the limiting ring 118 is fixed to the top of the sub-beam 111, and the limiting post 119 is fixed to the bottom of the connecting member.

[0060] The limiting ring 118 has a through-hole that extends from top to bottom. The limiting hole has a circular outline, and the limiting post 119 has a circular cross-section. The difference between the diameter of the limiting hole and the outer diameter of the limiting post 119 is 2~5mm.

[0061] The gap between the limiting ring 118 and the limiting post 119 allows them to move smoothly vertically, enabling them to work in conjunction with the elastic element 115 and providing better cushioning. Simultaneously, the limiting element restricts the horizontal displacement of the shock-absorbing frame 1, effectively preventing significant swaying and ensuring stable support for the gas cylinder 2.

[0062] The shock-absorbing frame 1 includes a mounting bracket 12 connecting two supports 11, with the two mounting brackets 12 spaced longitudinally between each other. The mounting bracket 12 extends laterally for mounting buffer tanks. The buffer tanks are mounted on the mounting brackets 12, and both ends of the buffer tanks are connected to the mounting brackets 12 axially. In this embodiment, each mounting bracket 12 is provided with one buffer tank, that is, the two buffer tanks are arranged on opposite sides of the gas cylinder 2.

[0063] The buffer tank is used to balance the pressure difference between the supply and demand gases by storing and releasing gases during vehicle operation, thereby ensuring stable vehicle operation. That is, when the gas pressure in gas cylinder 2 is high, the gas is released into the buffer tank; when the gas pressure in the gas cylinder is insufficient, the gas in the buffer tank enters the gas cylinder.

[0064] Mounting bracket 12 is connected to the lower wing plate 1112.

[0065] For example, during installation, the shock-absorbing frame 1 is first installed by threading the support column 114 upwards through the bottom of the upper flange 1111 of the sub-beam 111, then threading the support column 114 through the bottom plate 1133 of the bent member 113, then threading it. Next, the sub-beam 111 is detachably connected to the main beam. Then, the connecting plate is fixed to the bottom of the gas cylinder 2. Finally, the bent member 113 and the connecting member are welded together. In summary, the shock-absorbing frame 1 of this application has the following advantages: 1. The gas cylinder 2 is fixedly connected to the gas cylinder 2 through the connector, and then connected to the sub-beam 111 through the support column 114 and elastic element 115, etc., to achieve a flexible connection between the gas cylinder 2 and the vehicle frame, so that there is elastic buffer between the two, which can buffer the vibration generated during the vehicle's operation, absorb the stress generated by the torsion of the vehicle frame, and effectively prevent the gas cylinder 2 from breaking or being damaged.

[0066] 2. The connection between the connector and the gas cylinder 2 is fixed, increasing the connection strength and preventing cylinder rotation. The connection between the connector and the sub-beam 111 is achieved through the bending member 113, support column 114, and elastic member 115. Therefore, the upper crossbeam and strap sleeve structures used in related technologies are eliminated, reducing the weight of the entire shock-absorbing frame 1 and thus lowering costs. After the connector is fixedly connected to the gas cylinder 2, the gas cylinder 2 can maintain a horizontal position during vehicle operation through the expansion and contraction of multiple elastic members 115 located at its bottom and on opposite sides, overcoming twisting and preventing pipe breakage.

[0067] 3. The gap between the limiting ring 118 and the limiting post 119 allows them to move smoothly in the vertical direction, enabling them to work in conjunction with the elastic element 115 and providing better cushioning. At the same time, the limiting element restricts the displacement of the shock-absorbing frame 1 in the horizontal direction, thereby effectively preventing the shock-absorbing frame 1 from shaking significantly and ensuring stable support for the gas cylinder 2.

[0068] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
