Description

Pipe clamp, brake oil pipe assembly and vehicle Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a pipeline clamp, a brake oil pipe assembly and a vehicle. Background Art

[0002] In a vehicle's braking system, pipe clamps play a crucial role, securing the brake hose to the vehicle's chassis and ensuring that the hose routing meets design requirements. Poor durability of the pipe clamps can pose risks to the entire vehicle's brake hose, compromising driving safety. In related technologies, poor pipe clamp durability can easily cause the brake hose to detach, impacting the vehicle's overall handling.

[0003] Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a pipe clamp, a brake oil pipe assembly, and a vehicle. The pipe clamp has a strong fixing effect on the brake oil pipe, has excellent durability, and effectively prevents the brake oil pipe from easily falling out of the pipe clamp.

[0005] A first embodiment of the present invention provides a pipeline clamp, comprising:

[0006] Mounting structure;

[0007] The pipe clamping structure is arranged along the second direction with the mounting structure, and the pipe clamping structure includes a pipe groove portion, a guide portion, a hook portion and an inner pad portion. The guide portion and the hook portion are both arranged on one side of the pipe groove portion in the third direction and connected to the pipe groove portion. The guide portion and the hook portion are spaced apart along the second direction and jointly define a pipe inlet. The guide portion and the pipe groove portion are both connected to the mounting structure. The inner pad portion is respectively connected to the inner side surface of the pipe groove portion and the inner side surface of the hook portion, and forms a pipe clamping hole extending along the first direction. The pipe inlet and the pipe clamping hole are connected. The hook portion and the inner pad portion are configured to be able to bend to enlarge the pipe inlet. The first direction, the second direction and the third direction are perpendicular to each other.

[0008] The pipeline clamp according to the embodiment of the first aspect of the present invention has at least the following beneficial effects: through the installation structure, the pipeline clamp can be installed on the chassis of the vehicle, and through the pipe clamping structure, the brake oil pipe can be firmly fixed on the pipeline clamp, so that the brake oil pipe can be laid out on the chassis of the vehicle according to the design requirements. In the pipe clamping structure, the guide portion and the hook portion are located on one side of the opening of the pipe groove portion, and the guide portion and the hook portion define a pipe entrance between each other. Inner pads are provided on the inner side surfaces of the pipe groove portion and the inner side surfaces of the hook portion, so that the inner pads form a pipe clamping hole. During the assembly of the brake oil pipe, an external force is applied to the hook portion to drive the hook portion and the corresponding inner pad to bend and deform, thereby expanding the pipe entrance, so that the brake oil pipe can smoothly enter the pipe clamping hole from between the guide portion and the hook portion; since the inner pad is prone to elastic deformation, when the brake oil pipe is placed in the pipe clamping hole, the hook portion and the corresponding inner pad can be driven to return to their original state to reduce the pipe entrance, thereby preventing the brake oil pipe from easily escaping from the pipe clamping hole through the pipe entrance.

[0009] The inner pad can increase the friction between the brake oil pipe and the pipe clamp, so that the pipe clamp can exert a stronger clamping and fixing effect on the brake oil pipe, making it difficult for the brake oil pipe to move axially in the pipe clamp and to escape from the pipe clamp.

[0010] The pipeline clamp adopts the above-mentioned structural design, which not only improves the rigidity of the pipeline clamp at the pipeline inlet, thereby increasing the pull-out force of the brake oil pipe in the pipeline clamp, so that the pipeline clamp can stably clamp the brake oil pipe, thereby ensuring that the brake oil pipe is not easily separated from the pipeline clamp. Moreover, the automatic recovery characteristics of the inner pad can make the hook part more easily return to its original state after the external force is removed, and effectively avoid the hook part from being easily broken and affecting the performance of the pipeline clamp, thereby improving the durability of the pipeline clamp.

[0011] In some embodiments of the present invention, the guide portion is provided with a first guide surface, which is inclined toward the tube groove portion along the direction from the guide portion to the hook portion, and the hook portion is provided with a second guide surface, which is inclined toward the tube groove portion along the direction from the hook portion to the guide portion, and the first guide surface and the second guide surface jointly define the pipeline inlet.

[0012] In some embodiments of the present invention, a first angle is formed between the first guide surface and the third direction, a second angle is formed between the second guide surface and the third direction, and the first angle is smaller than the second angle.

[0013] In some embodiments of the present invention, the minimum opening distance of the pipeline inlet in the second direction is set to a first distance, the bending distance of the hook portion in the second direction is set to a second distance, and the sum of the first distance and the second distance is less than the diameter of the pipeline clamping hole.

[0014] In some embodiments of the present invention, the second distance is greater than the first distance.

[0015] In some embodiments of the present invention, the pipe clamping hole has a central axis extending along a third direction, and the end of the hook portion close to the guide portion is a pressing end for abutting the pipe, and the connection between the pressing end and the inner pad is located on the side of the central axis away from the guide portion, and the pressing end is at least partially located on the side of the central axis close to the guide portion.

[0017] In some embodiments of the present invention, the tube groove portion is provided with a rounded corner, the rounded corner is located on a side of the tube groove portion away from the mounting structure, and the radius of the rounded corner is larger than the radius of the pipeline clamping hole.

[0018] In some embodiments of the present invention, the tube groove portion is provided with a groove, the groove is located at the rounded corner, the inner pad portion is provided with a convex portion, and the convex portion and the groove are engaged and connected.

[0019] In some embodiments of the present invention, the inner pad portion is connected to the tube groove portion and the hook portion respectively through an injection molding process, and the hook portion, the guide portion and the tube groove portion are integrally formed.

[0020] In some embodiments of the present invention, the pipe clamping hole has an inner diameter smaller than an outer diameter of the pipe.

[0021] In some embodiments of the present invention, there is one tube clamping structure; or, there are two tube clamping structures, and the two tube clamping structures are respectively located on both sides of the mounting structure in the second direction.

[0022] A second embodiment of the present invention provides a brake oil pipe assembly, which includes the pipeline clamp as described in the first embodiment.

[0023] The brake oil pipe assembly according to the embodiment of the second aspect of the present invention has at least the following beneficial effects: the brake oil pipe assembly adopts the pipe clamp of the above structure, which can ensure that the brake oil pipe is tightly fixed in the pipe clamp and is not easily separated from the pipe clamp, thereby ensuring that the brake oil pipe can be used safely on the entire vehicle for a long time.

DETAILED DESCRIPTION

[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] In the description of the present invention, it should be understood that a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0039] The brake hose is the essential path for transmitting brake pressure in a vehicle. It serves as the link and bridge between the master cylinder and the four wheels. Because the master cylinder and the wheels are relatively far apart and there is considerable environmental data between them, the brake hose must be routed along the vehicle chassis. However, the hose is long and often runs alongside the vehicle body, making its routing complex.

[0040] In order to avoid relative movement between the brake oil pipe and the entire vehicle, the brake oil pipe needs to be fixed to the body with a pipe clamp. In addition, in order to prevent the pipeline from deviating from the designed state, fixed points are often added at shorter distances along the pipeline and fixed to the body with a pipe clamp, so that the pipe clamp can provide certain support and protection for the brake oil pipe.

[0041] In the structure of the brake hose assembly, whether the hose clamp is prone to falling off the vehicle body, whether the brake hose is prone to movement within the hose clamp, and whether the brake hose is prone to popping out of the hose clamp reflect the durability of the hose clamp. If the durability of the hose clamp does not meet the road test requirements, it will bring great risks to the use of the brake hose of the entire vehicle and affect driving safety. Therefore, the demand for improving the durability of the hose clamp is even stronger.

[0042] In the prior art, when the brake oil pipe is assembled on a vehicle and used, the brake oil pipe is easily detached from the pipe clamp due to the poor durability of the pipe clamp, thereby increasing the driving risk for the user.

[0043] Based on the above-mentioned technical problems, an embodiment of the present invention provides a pipeline clamp, a brake oil pipe assembly and a vehicle, which can improve the durability of the pipeline clamp, enhance the clamping and fixing effect of the pipeline clamp on the brake oil pipe, and effectively prevent the brake oil pipe from easily detaching from the pipeline clamp, thereby reducing the risk of using the brake oil pipe of the entire vehicle.

[0044] The following describes a pipeline clamp, a brake oil pipe assembly, and a vehicle according to an embodiment of the present invention with reference to FIG. 1 to FIG. 8 .

[0045] As shown in Figures 1 to 7, the pipeline clamp 100 according to the embodiment of the first aspect of the present invention has the advantages of unique structural design, high rigidity and practicality, and good durability. It can reduce the trial and error cycle and cost, and can be used in the braking system of an automobile to stably assemble the brake oil pipe 200 on the chassis of the entire vehicle.

[0046] The pipe clamp 100 has a first direction, a second direction, and a third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other. For better illustration, in this embodiment, it is assumed that the first direction is the front-to-back direction, the second direction is the left-to-right direction, and the third direction is the up-down direction.

[0047] The pipeline clamp 100 of this embodiment includes a mounting structure 180 and a pipe clamping structure.

[0048] The mounting structure 180 and the tube clamping structure are arranged along the second direction, and the mounting structure 180 and the tube clamping structure are connected.

[0049] Specifically, the mounting structure 180 is provided with a mounting hole 150 , the axial direction of the mounting hole 150 extends along the third direction, and the inner wall surface of the mounting hole 150 is provided with a plurality of latch teeth 160 , which are arranged at certain intervals along the axial direction of the mounting hole 150 .

[0050] It is understood that when the stud on the vehicle body is inserted into the mounting hole 150, the multiple latching teeth 160 will engage with the stud to prevent the stud from easily falling out of the mounting hole 150, thereby allowing the pipe clamp 100 to be fixed to the stud on the vehicle chassis through the mounting structure 180. The specific shape and size of the mounting structure 180 can be set according to actual needs and are not specifically limited here. By increasing the number of latching teeth 160 and reducing the spacing between two adjacent latching teeth 160, the pull-out force of the mounting structure 180 on the stud can be increased, making it difficult for the mounting structure 180 to fall off the stud, thereby preventing the pipe clamp 100 from easily falling off the vehicle and meeting the assembly force requirements of the pipe clamp 100 and the stud, such as an insertion force less than or equal to 100N and a pull-out force greater than or equal to 250N.

[0051] The pipe clamping structure is provided with a pipe clamping hole 130, which can exert a strong clamping and fixing effect on the brake oil pipe 200, so that the brake oil pipe 200 can be stably installed on the pipe clamp 100, so that the brake oil pipe 200 can be laid out on the vehicle chassis according to the design requirements, allowing the brake oil pipe 200 to play its function in the braking system.

[0052] It is understood that in some examples, as shown in Figures 1 to 5 , a single clamping structure is provided, and the clamping structure can be located on the left or right side of the mounting structure 180. In this case, the pipeline clamp 100 is a single clamp, capable of securing only a single brake hose 200. In other examples, two clamping structures are provided, one on each side of the mounting structure 180 in the second direction, and the other symmetrically arranged about the mounting structure 180. In this case, the pipeline clamp 100 is a double clamp, capable of effectively securing two brake hoses 200 simultaneously.

[0053] The tube clamping structure includes a tube groove portion 119 , a guide portion 118 , a hook portion 113 and an inner pad portion 120 .

[0054] The tube groove portion 119 is recessed to form a groove body, and the opening of the groove body faces one side of the tube groove portion 119 in the third direction. The groove body extends through along the first direction, so that the tube groove portion 119 has an opening structure on both sides in the first direction, so that the brake oil pipe 200 can be assembled in the tube clamping structure along the first direction.

[0055] The guide portion 118 and the hook portion 113 are both located on the same side of the tube groove portion 119 in the third direction. In this case, the concave surface 116 of the groove body faces the guide portion 118 and the hook portion 113. Both the guide portion 118 and the hook portion 113 are fixedly connected to the tube groove portion 119. Furthermore, the guide portion 118 and the hook portion 113 are spaced apart along the second direction, so that the guide portion 118 and the hook portion 113 jointly define a pipeline inlet 140. Both the guide portion 118 and the tube groove portion 119 are fixedly connected to the mounting structure 180.

[0056] In this embodiment, the concave surface 116 of the tube groove portion 119 (i.e., the inner surface of the tube groove portion 119) faces upward, the guide portion 118 and the hook portion 113 are located above the tube groove portion 119, the guide portion 118 is located between the mounting structure 180 and the hook portion 113, the guide portion 118 is located on the left side of the tube groove portion 119, and the hook portion 113 is located on the right side of the tube groove portion 119. The guide portion 118, the hook portion 113, the tube groove portion 119, and the mounting structure 180 are connected using an integrated molding process, so that they together form the skeleton 110. The skeleton 110 is made of a hard material such as PA6 (also known as nylon 6 or polyamide 6) and can provide certain support and protection for the brake oil pipe 200. The hook portion 113 is generally U-shaped, so that the hook portion 113 can bend under the action of an external force, allowing the two ends of the hook portion 113 to approach each other.

[0057] The inner pad 120 extends along the inner side surfaces of the groove 119 and the hook 113 and is fixedly connected to the inner side surfaces of the groove 119 and the hook 113, respectively. In this manner, the inner pad 120 forms a pipe clamping hole 130, with the axial direction of the pipe clamping hole 130 extending in a first direction. As shown in FIG3 , the dotted circle represents the pipe clamping hole 130. The inner side surfaces of the groove 119 and the hook 113 both face the pipe clamping hole 130. The pipe clamping hole 130 and the pipe inlet 140 are interconnected, allowing the brake oil pipe 200 to enter the pipe clamping hole 130 through the pipe inlet 140. The hook 113 and the inner pad 120 are configured to bend and deform to increase the size of the pipe inlet 140.

[0058] In this embodiment, the pipeline inlet 140 is located above the pipeline clamping hole 130, and the inner pad 120 is made of a rubber material such as TPE (thermoplastic elastomer). The inner pad 120 is connected to the pipe groove portion 119 and the hook portion 113 respectively through an injection molding process. The inner pad 120 is provided with a plurality of ribs 122, and the ribs 122 and the inner pad 120 are made of the same material and are connected through an integral molding process. The plurality of ribs 122 are arranged at intervals around the circumference of the pipeline clamping hole 130, and there is a spacing groove between any two adjacent ribs 122. The plurality of ribs 122 are located in the groove body of the pipe groove portion 119, that is, the inner pad 120 corresponding to the pipe groove portion 119 is provided with a rib 122, and the inner pad 120 corresponding to the hook portion 113 is not provided with a rib 122. The number of ribs 122 can be set according to actual conditions and is not specifically limited here.

[0059] The rib 122 allows for easy elastic deformation during assembly of the brake hose 200 into the clamping structure, allowing the brake hose 200 to be fully positioned within the clamping hole 130 and allowing the hook 113 and the corresponding inner pad 120 to return to their original shape. Furthermore, the rib 122 cooperates with the free end of the hook 113 to effectively clamp and secure the brake hose 200.

[0060] It is understood that when the brake oil pipe 200 is installed in the pipe clamp structure, the pipe inlet 140 is too small to allow the brake oil pipe 200 to pass directly through. Therefore, the operator needs to apply a certain external force to the hook portion 113 to cause the hook portion 113 to bend and deform under the force. At this time, the inner pad 120 corresponding to the hook portion 113 is pulled by the hook portion 113 and bends and deforms. This causes the pipe inlet 140 to increase in size, thereby allowing the brake oil pipe 200 to pass through the pipe inlet 140 smoothly. At the same time, the guide portion 118 can guide the brake oil pipe 200 through the pipe inlet 140. Of course, when the force is applied to the hook portion 113, the hook portion 113 also causes the pipe groove portion 119 to deform, and the opening of the pipe groove portion 119 will become larger.

[0061] The guide portion 118 is disposed close to the mounting structure 180 . When the brake oil pipe 200 is squeezed into the pipe clamping hole 130 , the hook portion 113 is bent and deformed by the force, but the guide portion 118 does not bend and deform, and only serves as a guide.

[0062] Since the pipe clamp 100 of this embodiment adopts a uniquely designed pipe clamping structure, the guide portion 118 and the hook portion 113 are located on the opening side of the pipe groove portion 119, so that the guide portion 118 and the hook portion 113 define a pipe inlet 140 between each other, and inner pads 120 are provided on the inner side surfaces of the pipe groove portion 119 and the inner side surfaces of the hook portion 113, so that the inner pads 120 can form a pipe clamping hole 130 on the frame 110. Therefore, during the assembly process of the brake oil pipe 200, by applying an external force to the hook portion 113, the hook portion 113 and the corresponding inner pad 120 are driven to undergo a certain bending deformation, thereby expanding the size of the pipe inlet 140 in the second direction, allowing the brake oil pipe 200 to smoothly enter the pipe clamping hole 130 from between the guide portion 118 and the hook portion 113.

[0063] Since the inner pad 120 is prone to elastic deformation, when the brake oil pipe 200 is placed in the pipe clamping hole 130, the inner pad 120 will be compressed and deformed by the pressure of the brake oil pipe 200, so that the brake oil pipe 200 is closer to the pipe groove 119. At this time, a certain amount of space can be vacated between the brake oil pipe 200 and the hook portion 113, so that the hook portion 113 and the corresponding inner pad 120 can return to their original state, thereby reducing the size of the pipe inlet 140. At this time, the brake oil pipe 200 cannot pass through the small-sized pipe inlet 140. The hook portion 113 will limit the brake oil pipe 200, thereby preventing the brake oil pipe 200 from easily escaping from the pipe clamping hole 130 through the pipe inlet 140.

[0064] Furthermore, the inner pad 120 increases friction between the brake hose 200 and the pipe clamp 100, providing a stronger clamping effect on the brake hose 200. This prevents the brake hose 200 from axial movement or separation within the pipe clamp 100. The inner pad 120 is made of soft rubber and will not damage the brake hose 200.

[0065] It is understandable that the pipe clamp 100 of this embodiment can make the original size of the pipe inlet 140 smaller by adopting the above-mentioned structural design. The size of the pipe inlet 140 is adjusted by the bending deformation of the hook portion 113, so that the brake oil pipe 200 can pass through the pipe inlet 140 smoothly. Moreover, since no soft rubber material is provided at the pipe inlet 140 to adjust the size of the pipe inlet 140, such as by extending the inner pad 120 to the pipe inlet 140, there is no possibility that the brake oil pipe 200 is squeezed by the easily deformable soft rubber material when passing through the pipe inlet 140. In the event of contact, the brake oil pipe 200 will not easily fall out of the pipe inlet 140 by squeezing the soft rubber material at the pipe inlet 140. Therefore, the above-mentioned structural setting can improve the rigidity of the pipe clamp 100 at the pipe inlet 140, thereby increasing the pull-out force of the brake oil pipe 200 in the pipe clamp 100, that is, a greater external force is required to remove the brake oil pipe 200 from the pipe clamp 100, so that the pipe clamp 100 can stably clamp the brake oil pipe 200, ensuring that the brake oil pipe 200 is not easy to fall out of the pipe clamp 100, and ultimately increasing the durability of the pipe clamp 100.

[0066] In addition, the self-restoring shape characteristic of the inner pad 120 is effectively utilized to make the hook portion 113 more likely to return to its original state after the external force is removed, and effectively avoid the problem that the hook portion 113 is easily broken, resulting in the failure of the limiting and fixing effect of the hook portion 113 on the brake oil pipe 200, thereby affecting the performance of the pipeline clamp 100, and ultimately further improving the durability of the pipeline clamp 100.

[0067] The hook portion 113 is easily broken when it is bent and deformed by an external force. Therefore, by extending the inner pad 120 along the inner side surface of the hook portion 113, not only can the hook portion 113 and the corresponding inner pad 120 be bent and deformed to maximize the expansion of the pipeline inlet 140, so that the original size of the pipeline inlet 140 can be designed to be smaller, and the hook portion 113 can be restored to its original shape more easily and quickly, making the hook portion 113 less likely to break, but also the connection area between the inner pad 120 and the hook portion 113 can be increased, thereby enhancing the connection effect between the inner pad 120 and the hook portion 113, avoiding the inner pad 120 and the hook portion 113 from being easily separated, resulting in the inner pad 120 failing to act on the hook portion 113, causing the hook portion 113 to be easily broken and lose its fixing and supporting function for the brake oil pipe 200, thereby ensuring the performance of the pipeline clamp 100.

[0068] In some embodiments, as shown in Figures 3 to 5, the guide portion 118 is provided with a first guide surface 112, which is arranged obliquely toward the pipe groove portion 119 along the direction from the guide portion 118 to the hook portion 113. Furthermore, the hook portion 113 is provided with a second guide surface 114, which is arranged obliquely toward the pipe groove portion 119 along the direction from the hook portion 113 to the guide portion 118. The first guide surface 112 and the second guide surface 114 jointly define a pipe inlet 140.

[0069] In this embodiment, as shown in Figures 3 and 5 , both the first guide surface 112 and the second guide surface 114 are flat. The first guide surface 112 tilts rightward from top to bottom, while the second guide surface 114 tilts leftward from top to bottom. The first and second guide surfaces 112, 114 form a pipeline inlet 140 in the shape of an inverted "eight." This configuration allows the hook portion 113 and the corresponding inner pad portion 120 to undergo a greater degree of bending deformation. For example, the hook portion 113 can be bent until the second guide surface 114 and the first guide surface 112 are parallel, allowing the brake oil pipe 200 to pass smoothly through the pipeline inlet 140. Furthermore, the original size of the pipeline inlet 140 can be designed to be smaller, thereby making it more difficult for the brake oil pipe 200 to escape from the pipeline clamping hole 130. After the hook portion 113 returns to its original shape, the pipeline inlet 140 returns to its original size.

[0070] Of course, it is not ruled out that in some embodiments the second guide surface 114 is extended along the third direction.

[0071] Furthermore, as shown in Figures 3 and 5, when both the first guide surface 112 and the second guide surface 114 are inclined, a first angle is formed between the first guide surface 112 and the third direction, and a second angle is formed between the second guide surface 114 and the third direction. The first angle is smaller than the second angle, that is, the inclination angle of the second guide surface 114 is greater than the inclination angle of the first guide surface 112. This can increase the amplitude of the bending deformation of the hook portion 113, thereby further reducing the original size of the pipeline inlet 140, making it more difficult for the brake oil pipe 200 to detach from the pipeline clamp 100, and ensuring that the pipeline clamp 100 has better durability.

[0072] The inclination angle of the first guide surface 112 and the inclination angle of the second guide surface 114 can be set according to actual conditions. In this embodiment, the inclination angle of the first guide surface 112 is 15°, and the inclination angle of the second guide surface 114 is 25°.

[0073] It is understood that by selecting an appropriate inclination angle of the second guide surface 114, the hook portion 113 can bend and deform more significantly, while also ensuring that the hook portion 113 is less likely to fold outward from the pipe clamping hole 130 when subjected to pressure from the brake oil pipe 200 within the pipe clamping hole 130. Furthermore, the inner pad 120 is disposed along the inner side of the hook portion 113 to provide an obstruction when the hook portion 113 folds outward from the pipe clamping hole 130, thereby preventing the hook portion 113 from folding outward from the pipe clamping hole 130.

[0074] As shown in FIG3 , the minimum opening distance of the pipeline inlet 140 in the second direction is set to a first distance D1 , the bending distance of the hook portion 113 in the second direction is set to a second distance D2 , and the sum of the first distance D1 and the second distance D2 is smaller than the diameter of the pipeline clamping hole 130 .

[0075] It is understood that although the size of the conduit inlet 140 can be adjusted by bending and deforming the hook portion 113, when the hook portion 113 returns to its original shape, the conduit inlet 140 becomes smaller and has a minimum opening distance. The specific values ​​of the first distance D1 and the second distance D2 can be set according to actual conditions.

[0076] Because the inner diameter of pipe clamping hole 130 is equal to or smaller than the outer diameter of the pipe, and the sum of first distance D1 and second distance D2 is smaller than the diameter of pipe clamping hole 130, when brake hose 200 is assembled into pipe clamping hole 130, the operator must not only bend hook portion 113 but also oscillate the portion of pipe groove 119 connected to hook portion 113 outward by a certain angle, thereby further expanding pipe inlet 140. At this point, the opening of pipe groove 119 becomes larger. After brake hose 200 is assembled, hook portion 113 and pipe groove 119 return to their original shapes due to elasticity.

[0077] In this embodiment, the inner diameter of the pipe clamping hole 130 is smaller than the outer diameter of the pipe. By reducing the inner diameter of the pipe clamping hole 130, the clamping force of the pipe clamp 100 on the brake hose 200 is increased, thereby reducing the axial force of the brake hose 200 within the pipe clamping hole 130, making the brake hose 200 less likely to move and keeping the brake hose 200 firmly fixed to the pipe clamp 100.

[0078] Then, the brake oil pipe 200 will not only be subjected to the force exerted by the hook portion 113 and the inner pad portion 120, but also to the force exerted by the pipe groove portion 119, prompting the brake oil pipe 200 to be tightly fixed on the pipeline clamp 100, thereby meeting the design requirements of the insertion force, extraction force and axial force of the brake oil pipe 200, for example, the insertion force is less than or equal to 70N, the extraction force is greater than or equal to 100N, and the axial force is greater than or equal to 10N, meeting the durability test requirements of the whole vehicle.

[0079] 3 , the second distance D2 is greater than the first distance D1 . This design allows the hook portion 113 to bend more significantly and reduces the original size of the pipe inlet 140 , thereby increasing the difficulty of the brake oil pipe 200 being released from the pipe clamping hole 130 .

[0080] In some embodiments, as shown in FIG3 , the pipe clamping hole 130 has a central axis 170 extending along a third direction. The end of the hook portion 113 near the guide portion 118 is a pressing end, which can be used to abut the pipe. Furthermore, the connection between the pressing end and the inner pad 120 is located on the side of the central axis 170 away from the guide portion 118, and the pressing end is at least partially located on the side of the central axis 170 near the guide portion 118. In this case, the pipe inlet 140 is completely located on the side of the central axis 170 near the guide portion 118.

[0081] With this design, the brake hose 200 within the pipe clamping hole 130 is pressed against the hook portion 113, forcing the brake hose 200 to rest against the rib 122 of the inner pad 120. This prevents the brake hose 200 from axially moving within the pipe clamping hole 130 or from falling out of the pipe clamping hole 130. Furthermore, even if the brake hose 200 moves toward the pipe inlet 140, the pressing end of the hook portion 113 will hinder the brake hose 200, confining it within the pipe clamping hole 130.

[0082] In this embodiment, the inner pad 120 corresponding to the hook portion 113 is provided with an arc surface, which is located above the pipeline clamping hole 130. The arc surface will fit in contact with the outer peripheral surface of the brake oil pipe 200 in the pipeline clamping hole 130, increasing the contact area between the inner pad 120 and the brake oil pipe 200, thereby enhancing the friction between the brake oil pipe 200 and the inner pad 120.

[0083] As shown in Figures 3 and 5 , the hook portion 113 comprises a first connecting section, a second connecting section, and a third connecting section. One end of the first connecting section is fixedly connected to the tube groove portion 119 . The first connecting section extends along the third direction and is fixedly connected to one end of the second connecting section. The second connecting section extends along the second direction and is fixedly connected to one end of the third connecting section. The third connecting section extends along the inclined direction of the second guide surface 114 .

[0084] In this embodiment, the first connecting segment, the second connecting segment, and the third connecting segment are sequentially connected through an integral molding process. A certain distance exists between the third connecting segment and the first connecting segment in the second direction, allowing the hook portion 113 to bend and deform, allowing the third connecting segment to approach the first connecting segment, and allowing an inner pad 120 to be provided on the hook portion 113. The inner pad 120 includes a hook segment 123, which is provided corresponding to the hook portion 113 and extends sequentially along the first connecting segment, the second connecting segment, and the third connecting segment. The hook segments 123 are spaced a certain distance D2 in the second direction, allowing both the hook portion 113 and the hook segment 123 to bend and deform.

[0085] Furthermore, as shown in Figures 3 to 7, the first connecting section of the hook portion 113 is provided with a limiting protrusion 117. The limiting protrusion 117 is located on the surface of the first connecting section facing the hook section 123, that is, the limiting protrusion 117 is located on the inner side of the hook portion 113. The limiting protrusion 117 is provided near the pressing end and is integrally formed with the hook portion 113. The hook section 123 of the inner pad 120 is provided with a limiting groove 124, which is engaged with the limiting protrusion 117 and can be semicircular.

[0086] When the pressing end of the hook portion 113 and its corresponding inner pad 120 abut against the upper end of the brake oil pipe 200, the inner pad 120 is subjected to the force of the brake oil pipe 200, which can easily cause the inner pad 120 to displace relative to the hook portion 113, resulting in the inner pad 120 separating from the hook portion 113 or even detaching from the frame 110, which can easily cause the hook portion 113 to break. Therefore, this embodiment provides a limiting groove 124 and a limiting protrusion 117. The limiting protrusion 117 can limit the displacement of the hook portion 123 relative to the hook portion 113 due to the force of the brake oil pipe 200, thereby ensuring that the inner pad 120 and the hook portion 113 maintain a good connection and are not easily separated.

[0087] In some embodiments, as shown in Figures 1 to 7 , the tube groove portion 119 has a rounded corner 111. Rounded corner 111 is located on the side of the tube groove portion 119 away from the mounting structure 180. Rounded corner 111 is also located on the side of the tube groove portion 119 away from the hook portion 113, and its central angle is 90°. Furthermore, the radius of rounded corner 111 is greater than the radius of the pipe clamping hole 130. In this case, the pipe inlet 140 is positioned near the mounting structure 180. The center of rounded corner 111 may or may not coincide with the center of the pipe clamping hole 130.

[0088] By increasing the size of the fillet 111 through the above-mentioned arrangement, the resilience of the tube groove 119 is increased, the deformation of the tube groove 119 is increased, and the pipe clamp 100 is less likely to break. Furthermore, while the worker is bending and deforming the hook 113, it is easier to swing the tube groove 119 outward, thereby reducing the difficulty of assembling the brake hose 200. Furthermore, during the assembly of the brake hose 200, the size of the pipe inlet 140 is enlarged by the bending deformation of the hook 113 and the deformation of the tube groove 119. Therefore, this design can further reduce the original size of the pipe inlet 140, thereby making it more difficult for the brake hose 200 to be removed from the pipe clamp 100.

[0089] Furthermore, as shown in Figures 1 to 7, the inner side surface of the tube groove portion 119 is recessed to form a groove 115, which is located at the rounded corner 111 and is positioned corresponding to the rounded corner 111 of the tube groove portion 119. The inner pad portion 120 is provided with a protrusion 121, which is integrally formed with the inner pad portion 120 and is engaged with the groove 115.

[0090] In this embodiment, the groove 115 adopts a dovetail groove design.

[0091] Through the above design, not only the connection area between the inner pad 120 and the skeleton 110 can be increased, the connection effect between the inner pad 120 and the skeleton 110 can be strengthened, and the inner pad 120 can be prevented from easily detaching from the skeleton 110, but also the thickness of the tube groove portion 119 at the rounded corner 111 can be reduced. Therefore, when the tube groove portion 119 is bent outward, the rounded corner 111 of the tube groove portion 119 is more likely to undergo greater deformation, which makes it easier and faster for the brake oil pipe 200 to be inserted into the pipe clamping hole 130.

[0092] The number of grooves 115 is set to one. By reducing the number of grooves 115 on the pipe groove portion 119, the deformation of other positions of the pipe groove portion 119 can be reduced, thereby improving the rigidity of the pipeline clamp 100, increasing the pull-out force of the brake oil pipe 200 in the pipeline clamping hole 130, effectively preventing the brake oil pipe 200 from easily detaching from the pipeline clamp 100, and improving the durability of the pipeline clamp 100.

[0093] In this embodiment, since the inner pad portion 120 is fixedly connected to the frame 110 through a two-material injection molding process, and the hook portion 113, the guide portion 118, the pipe groove portion 119 and the mounting structure 180 are connected through an integrated molding process, the inner pad portion 120 is not easily detached from the frame 110. Moreover, the connection between the hook portion 113, the guide portion 118 and the pipe groove portion 119 is strong and not easy to break, thereby improving the durability of the pipeline clamp 100.

[0094] As shown in FIG. 1 to FIG. 8 , a brake oil pipe assembly according to an embodiment of the second aspect of the present invention includes a brake oil pipe 200 and a pipeline clamp 100 according to the embodiment of the first aspect.

[0095] The number of brake oil pipes 200 is not limited to one. In the brake oil pipe assembly, there are four brake oil pipes 200: a left front oil pipe, a left rear oil pipe, a right front oil pipe, and a right rear oil pipe. These can be installed on the vehicle using multiple pipe clamps 100. The brake oil pipes 200 are then connected to the master cylinder and the brake caliper via pipe joints 300.

[0096] The brake oil pipe assembly of this embodiment adopts the pipe clamp 100 of the above structure, which can tightly fix the brake oil pipe 200 in the pipe clamp 100, preventing the brake oil pipe 200 from easily detaching from the pipe clamp 100, thereby ensuring that the brake oil pipe 200 can be used safely on the vehicle for a long time.

[0097] In addition, the vehicle according to the third embodiment of the present invention includes the brake oil pipe assembly according to the second embodiment.

[0098] Specifically, the vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. It can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. It can be a gasoline vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0099] The vehicle of this embodiment adopts the brake oil pipe assembly of the above structure, which can stably install the brake oil pipe 200 on the vehicle chassis through the pipe clamp 100, preventing the brake oil pipe 200 from easily falling out of the pipe clamp 100 and affecting the driving condition of the entire vehicle, thereby helping to reduce driving risks.
