Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to a pipeline restraint structure and a vehicle. Background Art

[0002] For some vehicles, such as medium and heavy trucks, the main brake valve is usually installed on the front panel of the cab, while the energy storage device, front and rear axle modules, other valve bodies and control units are generally arranged on the chassis. These components arranged on the chassis need to be operated and controlled by the main brake valve, so pipelines are needed to connect these components to the main brake valve.

[0003] In order to reduce the impact of road bumps on the driver, the cab and chassis are generally connected by non-rigid connections such as four-point suspension, which makes the cab shake more on the chassis. The pipelines connecting the main brake valve and those components on the chassis also need to be set to a certain length to accommodate this shaking.

[0004] At present, the method of bending pipelines in large arcs is commonly used to make pipelines adapt to this use environment. However, this method can easily cause the pipelines to be too long, making it easy for the pipelines to rub and collide with surrounding parts during vehicle use, that is, it can easily cause interference between the pipelines and surrounding parts, and even cause the risk of pipeline collapse. Summary of the invention

[0005] The present application provides a pipeline restraint structure and a vehicle to solve the problem that the pipeline is prone to interfere with surrounding components during vehicle use, and even causes the risk of pipeline collapse.

[0006] In order to solve the above problems, this application adopts the following technical solutions:

[0007] A first aspect of the present application provides a pipeline constraint structure for limiting the movement range of the pipeline, comprising a connecting portion and two supporting spring plates respectively arranged at both ends of the connecting portion, and two positioning components, wherein the positioning components are correspondingly rotationally connected to the supporting spring plates, and the rotation direction of the positioning components is the same as the extension direction of the connecting portion, and the positioning components have a pipeline groove for the pipeline to pass through, and can lock the pipeline in the pipeline groove.

[0008] In some possible designs, the supporting elastic sheet is configured to be arc-shaped, and the two supporting elastic sheets are bent toward each other.

[0009] In some possible designs, one end of the supporting spring sheet away from the connecting portion is bent to form a mounting portion, the mounting portions of two supporting spring sheets are parallel to each other, and the positioning assembly is rotatably connected to the mounting portion.

[0010] In some possible designs, a pin shaft is also included, and the mounting portion includes a first mounting spring sheet and a second mounting spring sheet that are parallel to each other, and the first mounting spring sheet and the second mounting spring sheet are both provided with first mounting holes corresponding to each other, and a connecting ear is provided on the positioning component, and a second mounting hole corresponding to the first mounting hole is provided on the connecting ear, so that the mounting portion can be rotatably connected to the positioning component by passing the pin shaft through the first mounting hole and the second mounting hole.

[0011] In some possible designs, a limiting portion is provided at one end of the pin shaft, and a limiting hole is provided at the other end. A removable retaining spring is provided in the limiting hole, and one of the connecting ear and the connecting portion abuts against the limiting portion, and the other abuts against the retaining spring.

[0012] In some possible designs, the connecting portion includes a first connecting elastic sheet and two second connecting elastic sheets arranged at both ends of the first connecting elastic sheet, the two second connecting elastic sheets are parallel to each other, and each of the second connecting elastic sheets is connected to one of the supporting elastic sheets.

[0013] In some possible designs, at least two connection holes are provided on the first connection spring sheet, and the connection holes are used to connect to the chassis bracket of the vehicle.

[0014] In some possible designs, the positioning assembly includes an arc-shaped plate and a stopper, the arc-shaped plate forming the pipeline groove with an opening on one side, and the stopper is used to lock the pipeline in the pipeline groove after the pipeline enters the pipeline groove.

[0015] In some possible designs, at least one positioning hole is provided on both sides of the center line of the arc-shaped plate, and the limiting member is a binding strap, which is used to pass through at least two of the positioning holes to lock the pipeline in the pipeline groove.

[0016] A second aspect of the present application provides a vehicle, comprising a pipeline, a chassis bracket, and a pipeline restraint structure as described in any one of the first aspects, wherein the pipeline restraint structure is fixed to the chassis bracket to limit the movement range of the pipeline.

[0017] In the pipeline constraint structure and vehicle provided by the present application, the pipeline constraint structure limits the movement range of the pipeline by setting a connecting part, two supporting springs arranged at both ends of the connecting part and two positioning components, wherein each supporting spring is connected to a positioning component, and the positioning component can rotate relative to the supporting spring, and the rotation direction is the same as the extension direction of the connecting part. The pipeline is passed through and locked in the pipeline groove of the positioning component. When the vehicle is driving, since the supporting spring has good elasticity and toughness, it can reduce the vibration amplitude of the pipeline, so that the pipeline can only shake within a predetermined range, and after the vibration ends, it automatically returns to its original position, and the positioning component can rotate to facilitate the rotation of the pipeline, so as to guide the pipeline while limiting the movement range of the pipeline, reduce the probability of collision and entanglement of the pipeline, and avoid interference between the pipeline and other components, thereby playing a good protective role for the pipeline.

Other features of the present application will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the implementation of the present invention described herein can be implemented in an order other than those illustrated or described herein, for example.

[0037] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0038] The chassis brake lines and cab of medium and heavy commercial trucks are connected through the main brake valve to realize brake operation control. The main brake valve is usually installed on the front wall of the cab. The energy storage device, front and rear axle modules and other valve bodies and control units are generally arranged on the chassis. The two are connected by special pipelines.

[0039] In order to reduce the impact of road bumps on the driver, non-rigid connection controls such as four-point suspension are adopted between the cab and the chassis. The cab shakes relatively much on the chassis, and the pipelines connecting the main brake valve and various components need to fully consider the influence of the relative bounce between the cab and the chassis. At the same time, when repairing and servicing the components and assemblies at the bottom of the cab, it is necessary to raise and lower the cab, which also puts relatively high requirements on the fixation and connection of the pipelines connected to the main brake valve.

[0040] At present, in order to adapt to the shaking of the cab and chassis and the impact of the cab flipping on the pipeline, the pipeline is generally adapted by large arc bending. In this method, the pipeline is generally longer, which can easily cause friction and collision between the pipeline and surrounding components during movement, resulting in the risk of interference and collapse between the pipeline and surrounding components.

[0041] To address this problem, in the prior art, a simple single-point fixation is also used to realize the constraint and connection of the pipeline, but this method still cannot avoid the risk of interference and collapse.

[0042] In order to avoid the above-mentioned problems, the present application provides a pipeline constraint structure and a vehicle, which can constrain the movement range of the pipeline used to connect the main brake valve and various components installed on the chassis, avoid interference between the pipeline and surrounding components, and thus provide better protection for the pipeline to avoid affecting vehicle control.

[0043] The technical solutions shown in the present application are described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

[0044] See also Figure 1 As shown, this embodiment provides a pipeline restraint structure, which is mainly used for positioning and restraining the pipeline 5 that needs to generate a certain displacement during use, so as to limit the movable range of the pipeline 5. For example, it can be used to restrain the pipeline 5 connected between the main brake valve on the cab of the vehicle and various components on the chassis.

[0045] It can be understood that the pipeline 5 mentioned in this embodiment can be one or more pipelines or lines, or a combination of pipelines and lines.

[0046] The pipeline restraint structure includes a connecting portion and two supporting springs 1 respectively arranged at both ends of the connecting portion, that is, the two supporting springs 1 are respectively connected at both ends of the connecting portion, and can be fixedly connected or detachably connected as long as they will not be separated during use.

[0047] The pipeline restraint structure also includes two positioning components. Each supporting spring piece 1 is rotatably connected to a positioning component, and the rotation direction of the positioning component is the same as the extension direction of the connecting part. The positioning component has a pipeline groove 4e for the pipeline 5 to pass through, and can lock the pipeline 5 in the pipeline groove 4e so that the pipeline 5 will not slide relative to the pipeline groove 4e.

[0048] It can be understood that the supporting spring piece 1 in this embodiment is made of a material with certain toughness and elasticity, such as a thin metal steel sheet of about 3 mm. Of course, it can also be made of other materials that can play a similar role. At the same time, the width of the supporting spring piece 1 and the size of the pipeline groove 4e can be adjusted according to the situation of the pipeline 5, and this embodiment does not limit them here.

[0049] Taking the fixing of the pipeline 5 on the vehicle as an example, the connection part can be first fixed on the chassis bracket 100 of the vehicle, and then the pipeline 5 can be inserted into the two pipeline grooves 4e successively, and the pipeline 5 can be locked in the pipeline groove 4e. During the operation of the vehicle, the good elasticity and toughness of the supporting spring sheet 1 can reduce the vibration amplitude of the pipeline 5 when the cab is bumping up and down during driving, and the supporting spring sheet 1 can quickly restore the deformation after the bumping, so that it automatically returns to the initial installation state. When the cab is flipped, etc., when the cab has a large position change, the positioning component can rotate relative to the supporting spring sheet 1, so that it is convenient for it to adapt to the movement of the cab. At the same time, the pipeline groove 4e can also guide the pipeline 5 so that the deformation of the pipeline 5 is limited within the designed range, thereby effectively controlling the movement deformation range and movement space of the pipeline 5, effectively preventing the pipeline 5 from rubbing or colliding with surrounding parts, etc., and having a good protective effect on the pipeline 5.

[0050] It is understandable that, in actual application, one or more of the above pipeline constraint structures may be selected for the same group of pipelines 5 according to the layout requirements of the pipelines 5 .

[0051] In some possible embodiments, the supporting spring clip 1 is arranged to be arc-shaped, and the two supporting spring clips 1 are bent in the direction of approaching each other, that is, the two supporting spring clips 1 are arranged opposite to each other, and the two positioning components are arranged at the ends of the two arc-shaped supporting spring clips 1. The two supporting spring clips 1 can realize double-point positioning of the pipeline, so that the pipeline 5 can move within a certain range through the two arc-shaped supporting spring clips 1, and at the same time, the automatic resetting ability of the supporting spring clip 1 can be improved.

[0052] It is understandable that the bending radius of the two supporting spring sheets 1 can be set to be slightly larger to further enhance the bearing capacity and deformation capacity thereof.

[0053] In addition, the supporting spring pieces 1 can also be in other shapes, for example, two supporting spring pieces 1 are parallel to each other in the shape of plates, or in the shape of plates at a certain angle, as long as the movement range of the pipeline 5 can be effectively restricted. This embodiment does not limit the shape of the supporting spring pieces 1.

[0054] For some possible implementations, see Figure 2 , Figure 3 As shown, one end of the supporting spring sheet 1 away from the connecting portion is bent 90 degrees to form a mounting portion 1d, the mounting portions 1d of the two supporting spring sheets 1 are parallel to each other, and the positioning assembly is rotatably connected to the mounting portion 1d.

[0055] Specifically, in order to have good variability, the supporting spring sheet 1 is generally thinner. To make the rotation direction of the positioning assembly the same as the extension direction of the connecting portion, it is generally necessary to add additional components to the end of the supporting spring sheet 1 by welding or bonding to rotate with the positioning assembly. In this embodiment, the supporting spring sheet 1 is directly bent 90° to form the mounting portion 1d, so that although the thickness of the mounting portion 1d is thin, the width of the end surface connected to the positioning assembly is wider, and no additional components are required to connect the positioning assembly, so that the weight that the supporting spring sheet 1 needs to bear can be reduced to a certain extent, and assembly and production are more convenient.

[0056] In some possible embodiments, the pipeline restraint structure also includes a pin shaft 2, and the mounting portion 1d includes a first mounting spring piece 1f and a second mounting spring piece 1g which are parallel to each other, and the first mounting spring piece 1f and the second mounting spring piece 1g are both provided with first mounting holes 1e which correspond to each other. It can be understood that the supporting spring piece 1 is rotated 90° to form the first mounting spring piece 1f, and the first mounting spring piece 1f is bent 180° away from one end of the connecting portion to form a second mounting spring piece 1g which is parallel to the first mounting spring piece 1f. A connecting ear 4d is provided on the positioning component, and a second mounting hole 4b corresponding to the first mounting hole 1e is provided on the connecting ear 4d, so that the pin shaft 2 passes through the first mounting hole 1e and the second mounting hole 4b, so that the mounting portion 1d is rotatably connected to the positioning component, that is, the positioning component can rotate 360° relative to the pin shaft 2, so that the pipeline groove 4e can adjust its direction in time to adapt to it when the cab moves relative to the chassis.

[0057] Exemplarily, one supporting spring sheet 1 is located above another supporting spring sheet 1, that is, the two are arranged symmetrically in the vertical direction, and the first mounting spring sheet 1f and the second mounting spring sheet 1g extend in the horizontal direction, and the distance between the first mounting spring sheets 1f of the two supporting spring sheets 1, or the distance between the two second mounting spring sheets 1g is equal. Of course, the specific distance can be set according to the size of the supporting spring sheets 1 actually set, for example, the distance is 20mm or 18mm, or other larger or smaller sizes, which is not limited in this embodiment.

[0058] The extension direction of the pin shaft 2 is perpendicular to the first mounting spring piece 1f, and the connecting ear 4d can be located on the side of the first mounting spring piece 1f away from the second mounting spring piece 1g, or the side of the second mounting spring piece 1g away from the first mounting spring piece 1f, as long as the first mounting hole 1e and the second mounting hole 4b are opposite to each other, so that after assembling the positioning assembly and the supporting spring piece 1, the positioning assembly can only rotate in the vertical direction through the first mounting spring piece 1f and the second mounting spring piece 1g.

[0059] Furthermore, a limiting portion 2a is provided at one end of the pin shaft 2, and a limiting hole is provided at the other end. A retaining spring 3 is detachably provided in the limiting hole. One of the connecting ear 4d and the connecting portion abuts against the limiting portion 2a, and the other abuts against the retaining spring 3.

[0060] Exemplarily, during assembly, the connecting ear 4d is affixed to the second mounting spring piece 1g, so that the pin shaft 2 passes through the second mounting hole 4b and the first mounting hole 1e in sequence, and then the limiting portion 2a is engaged with the side of the connecting ear 4d away from the second mounting spring piece 1g, and the limiting hole is located on the side of the first mounting spring piece 1f away from the second mounting spring piece 1g. At this time, the retaining spring 3 is inserted into one side of the limiting hole so that the retaining spring 3 is engaged with the side of the first mounting spring piece 1f away from the second mounting spring piece 1g.

[0061] Such a setting, on the one hand, can limit the movement of the connecting ear 4d through the first mounting spring piece 1f and the second mounting spring piece 1g so that it can only rotate in the vertical direction, and on the other hand, it can facilitate the assembly and separation of the positioning component and the supporting spring piece 1, thereby improving the convenience of use.

[0062] In some possible implementations, the connecting portion includes a first connecting elastic sheet 1a and two second connecting elastic sheets 1h disposed at both ends of the first connecting elastic sheet 1a, the two second connecting elastic sheets 1h are parallel to each other, and each second connecting elastic sheet 1h is connected to a supporting elastic sheet 1.

[0063] Exemplarily, the first connecting spring sheet 1a extends in the vertical direction, the two second connecting spring sheets 1h extend in the horizontal direction, and the projections of the second connecting spring sheets 1h and the supporting spring sheet 1 in the vertical direction are located on the same straight line, so that the connecting part and the supporting spring sheet 1 as a whole form a bowl-shaped structure.

[0064] During use, the first spring sheet and the supporting spring sheet 1 are connected by the second connecting spring sheet 1h, which can effectively increase the movement space of the supporting spring sheet 1 and help to improve the service life of the pipeline restraint structure.

[0065] It can be understood that the connecting part and the supporting spring sheet 1 can be integrally formed to improve the convenience of production and assembly, and improve the stability and reliability of use. In addition, it can also simplify the overall structure of the pipeline constraint structure, eliminate complex production and assembly processes, and further improve the convenience of using the pipeline constraint structure.

[0066] Furthermore, at least two connection holes 1b for installing the pipeline restraint structure are provided on the first connection spring sheet 1a. It is understandable that the connection hole 1b can be a threaded hole. When installing, corresponding threaded holes can be opened on the chassis bracket 100 of the vehicle or other components where the pipeline restraint structure needs to be assembled, and then screws are screwed into the threaded holes to fix the connection part on the component so that it does not rotate or move.

[0067] For some possible implementations, see Figure 6 As shown, the positioning assembly includes an arc plate 4 and a stopper. The arc plate 4 forms a pipeline groove 4e with an opening on one side. The stopper is used to lock the pipeline 5 in the pipeline groove 4e after the pipeline 5 enters the pipeline groove 4e.

[0068] Exemplarily, the limit member is located on the opening side of the pipeline groove 4e, and the limit member may include a connecting plate and a limit plate. The connecting plate and the limit plate may be connected by a spring. At the same time, one end of the connecting plate is hinged to the arc plate 4, and the other end is detachably connected to the arc plate 4 by means of a snap connection or a bolt connection.

[0069] First, separate one end of the connecting plate from the arc plate 4 so that the limiter does not block the opening of the pipeline groove 4e, then insert the pipeline 5 into the pipeline groove 4e, and connect the connecting plate to the arc plate 4. At this time, the spring will push the limiter plate toward the pipeline 5 and press the pipeline 5 into the pipeline groove 4e.

[0070] It can be understood that the limiting plates and the connecting plates can be of any shape, for example, both can be arc-shaped, which is not limited in this embodiment.

[0071] In some possible implementations, at least one positioning hole 4a is provided on both sides of the center line of the arc plate 4, and the limiting member is a binding belt 6, which is used to pass through at least two positioning holes 4a to lock the pipeline 5 in the pipeline groove 4e.

[0072] Exemplarily, a positioning hole 4a is provided on each side of the center line of the arc plate 4. After the pipeline 5 is placed in the pipeline groove 4e, one end of the binding strap 6 is passed through the two positioning holes 4a in sequence, and then wrapped around the outside of the pipeline groove 4e to be connected to the other end of the binding strap 6, so that the binding strap 6 is fixed on the arc plate 4 and can bind the pipeline 5 tightly in the pipeline groove 4e.

[0073] Exemplarily, two positioning holes 4a are provided on each side of the center line of the arc plate 4, and the two positioning holes 4a are arranged along the extension direction of the arc plate 4, and the positioning holes 4a on both sides of the center line correspond one to one. For pipelines 5 of different sizes, the strap 6 can be passed through the positioning holes 4a at different positions, thereby adjusting the binding position of the strap 6 so that the strap 6 can always press the pipeline 5 tightly in the pipeline groove 4e.

[0074] It is understandable that more positioning holes 4a can be set, which can be arranged in sequence along the extension direction of the arc plate 4 to accommodate pipelines 5 of different sizes. They can also extend along the width direction of the arc plate 4 to perform multiple fixations on the pipeline 5 from upper and lower positions through multiple straps 6, thereby effectively improving the fixing effect of the pipeline 5. This embodiment does not limit this.

[0075] In addition, the above embodiment is only an example to illustrate the structure of the positioning component, rather than to limit it. As long as the structure can fix the pipeline 5, it can be applied to the positioning component of this embodiment, and this embodiment does not limit it here.

[0076] An embodiment of the present application also provides a vehicle, which includes a pipeline 5, a chassis bracket 100, and the pipeline restraint structure in the above embodiment, wherein the pipeline restraint structure is fixed on the chassis bracket 100 to limit the movement range of the pipeline 5.

[0077] For example, the pipeline restraint structure is vertically fixed on the chassis bracket 100, that is, one supporting spring sheet 1 is located directly above another supporting spring sheet 1, and the positioning assembly can rotate in the vertical direction relative to the supporting spring sheet 1. The installed pipeline restraint structure is as follows: Figure 4 As shown in FIG. 1 , when the cab is displaced relative to the chassis, the pipeline restraint structure can be changed to Figure 5 After the cab is reset, the pipeline restraint structure automatically returns to the structure shown in Figure 4 Status shown.

[0078] The possible structure and working principle of the pipeline restraint structure are described in detail in the above embodiments, and will not be described in detail in this embodiment.

[0079] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments, and the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
