FIG. 2 is an assembled schematic view of an automotive brake hose mounting structure provided in accordance with one embodiment of the present utility model; fig. 3 is an exploded schematic view of the installation structure of the brake hose of the automobile in fig. 2. Referring to fig. 2 and 3, the present disclosure provides an automobile brake hose mounting structure including a mounting bracket 10, a brake hose 20 and a card 30. The brake hose 20 includes a hose connector 21 and a hose body 22, the hose connector 21 is connected to the hose body 22, and the mounting bracket 10 is provided with a clip connector a.

Fig. 4 is a schematic view of the card of fig. 2. Referring to fig. 4, the card 30 is provided with a joint via B and at least one protruding section 311, and the protruding section 311 is disposed at a periphery of the joint via B.

Referring to fig. 2, at least a portion of the hose connector 21 passes through the clamping interface a and the plug via B, and the protruding section 311 is configured such that the protruding section 311 is clamped between the mounting bracket 10 and the hose connector 21 under a turning motion.

In a specific application, a portion of hose coupler 21 can pass through clip interface a and coupler via B, and another portion cannot pass through clip interface a and coupler via B to provide a stop effect. During the installation process, the clamping piece 30 is arranged to enable the convex section 311 to be clamped between the hose connector 21 and the mounting bracket 10 under the condition of rotating around the axis of the hose connector 21, the hose connector 21 is jacked up until the hose connector 21 is abutted against the mounting bracket 10, and the convex section 311 is axially extruded to deform so as to generate axial pretightening force, so that the hose connector 21 is fixed on the mounting bracket 10. In this way, the brake hose 20 is connected to the mounting bracket 10 by the card 30.

It can be seen that the brake hose 20 can be connected to the mounting bracket 10 by rotating the card 30 provided by the present disclosure, the operation space required for mounting is small, the operation of workers is convenient, and the production efficiency is improved. Secondly, this card 30 is the annular enclosed construction that is equipped with joint via hole B, avoids appearing the problem that card 30 deviate from in the in-process of rotatory card 30, improves assembly efficiency.

In the present disclosure, the card 30 includes a plurality of the clamping portions 31 arranged on the circumferential side of the joint via B, each of the clamping portions 31 includes the protruding section 311, and the protruding sections 311 of each of the clamping portions 31 are symmetrically arranged about the center of the joint via B.

It will be appreciated that the plurality of protruding sections 311 are symmetrically arranged about the center of the joint via hole B, and accordingly, the plurality of protruding sections 311 are symmetrically arranged about the axis of the hose joint 21, i.e., the plurality of protruding sections 311 are uniformly spaced apart along the circumferential direction of the hose joint 21, thereby ensuring that the raised height of the hose joint 21 is uniform and preventing the hose joint 21 from tilting. It can be seen that the number of protruding sections 311 is at least 2 and is symmetrically arranged about the center of the joint through-hole B to avoid that the hose joint 21 is connected to the mounting bracket 10 in an inclined state.

In a specific application, in order to reduce the processing difficulty, the number of the clamping portions 31 is preferably 2, and correspondingly, the number of the protruding sections 311 is also 2. Of course, the number of the clamping portions 31 and the protruding sections 311 is not limited thereto, and it is sufficient to ensure that the protruding sections 311 on the clamping portions 31 are symmetrically arranged with respect to the center of the joint via B.

In the present disclosure, the card 30 further includes a plurality of abutting portions 32 arranged on the circumferential side of the joint via B, the abutting portions 32 abutting against the mounting bracket 10. The clamping portion 31 further includes a straight line segment 312, and the straight line segment 312 is connected to the protruding segment 311 and the abutting portion 32.

In this way, the card 30 provided in the present disclosure is a closed structure with the joint via hole B defined by the multiple clamping portions 31 and the multiple abutting portions 32, and the protruding section 311 is higher than the plane of the card 30.

Further, the convex section 311 and the abutting portion 32 are connected by a straight section 312. It should be noted that, this card 30 is thin sheet metal component, in specific production process, preferably through blanking technology one shot forming, set up the straightway 312 and can reduce the shaping degree of difficulty, guarantee the yields of card 30.

Referring to fig. 4, in the illustrated embodiment, the card 30 has a rectangular ring structure, the clamping portion 31 has two long sides of the rectangular ring structure, the abutting portion 32 has two short sides of the rectangular ring structure, and the long side exceeds the opening of the clamping port a, so that the abutting portion 32 can be ensured to abut against the mounting bracket 10, however, the shape of the card 30 is not limited thereto. In the embodiment shown in fig. 3, the mounting bracket 10 is provided with the card interface a having an opening structure, but the mounting bracket may be a through hole structure, and is not limited thereto.

Of course, the production process of the card 30 is not limited to the blanking process, and may be formed by a cutting and bending combination process, which is not particularly limited.

In the present disclosure, the convex section 311 includes a convex gentle slope section 3111 and a convex steep slope section 3112, and the projection length of the convex gentle slope section 3111 on the plane of the card 30 is greater than the projection length of the convex steep slope section 3112 on the plane of the card 30, so that the gradient of the convex gentle slope section 3111 is smaller than the gradient of the convex steep slope section 3112.

As stated above, the card 30 is arranged such that the engagement portion 31 is engaged between the hose connector 21 and the mounting bracket 10 under the pivoting movement, and the protruding section 311 is axially pressed. For example, during clockwise rotation of the card 30, the hose coupler 21 is moved from the raised gentle slope section 3111 toward the raised steep slope section 3112; during counterclockwise rotation of the card 30, the hose coupler 21 is moved from the raised steep slope section 3112 toward the raised gentle slope section 3111. In comparison, since the slope of the convex gentle slope segment 3111 is smaller than that of the convex steep slope segment 3112, the torque force provided by rotating the card 30 clockwise is much smaller than that provided by rotating the card 30 counterclockwise, so that the card 30 can be limited to rotate in one direction, and in addition, the torque force is reduced by the convex gentle slope segment 3111 to facilitate installation.

To further reduce the torque force required during installation, in the present disclosure, the peaks of the two raised sections 311 are offset.

In the embodiment shown in fig. 4, the convex gentle slope segment 3111 and the convex steep slope segment 3112 are both of an eccentrically arranged arc structure and are staggered in the long side direction of the rectangular ring structure, and of course, may be of a straight line structure, which is not limited in particular.

Of course, for ease of operation, in the embodiment of FIG. 4, one of the two abutments 32 is a flip-flop configuration, facilitating the tool action to provide torque.

Fig. 5 is a schematic view of the hose connector of fig. 2. Referring to fig. 2 and 5, the hose connector 21 includes a connector section 211, wherein the connector section 211 is provided with a clamping ring groove C and at least partially passes through the clamping port a and the connector through hole B. That is, the connector section 211 of the hose connector 21 is able to pass through the mounting bracket 10 and the card 30.

The joint segment 211 includes two circumferential convex portions 2111 located axially outward of the snap ring groove C, the two circumferential convex portions 2111 being symmetrically disposed about the axial center of the snap ring groove C. At least part of the protruding section 311 is disposed in the snap ring groove C and abuts against the corresponding circumferential convex portion 2111.

It can be seen that, in the process of rotating the card 30, the snap ring groove C is a space for the card 30 to rotate, and the two protruding sections 311 are limited by the two circumferential convex portions 2111, i.e. the circumferential convex portions 2111 act on the protruding sections 311 to deform the protruding sections 311. Further, the hose connector 21 further includes a stop collar protruding section 212, and the stop collar protruding section 212 is disposed at one axial end of the connector section 211 and abuts against the mounting bracket 10, so that the maximum axial length that the hose connector 21 can extend into is limited by the stop collar protruding section 212.

Further, the joint segment 211 further includes two circumferential flat portions 2112 located axially outward of the snap ring groove C, and the two circumferential flat portions 2112 are symmetrically disposed about the axial center of the snap ring groove C. The boss section 311 is provided to be rotated from the position of the corresponding peripheral flat surface portion 2112 against the corresponding peripheral convex surface portion 2111.

In a specific application, the car brake hose mounting structure is in an unlocked state when the protruding section 311 is located at the position of the peripheral flat portion 2112, and in a locked state when the protruding section 311 is located at the position of the peripheral convex portion 2111. That is, during rotation of the card 30, the boss section 311 moves between the position of the peripheral side flat surface portion 2112 and the position of the peripheral side convex surface portion 2111 to switch the state.

As can be appreciated, in the unlocked state, the hose connector 21 is allowed to pass through the connector via B because the peripheral side planar portion 2112 is not available for limiting purposes; in the locked state, the circumferential convex portion 2111 plays a role of a stopper, and the hose connector 21 cannot pass through the connector through hole B, so that the hose connector 21 can be connected to the mounting bracket 10.

In the embodiment shown in fig. 5, the radial distance between the two circumferential flat portions 2112 is smaller than the radial distance between the two circumferential convex portions 2111, and in the embodiment shown in fig. 1 and 4, the radial distance between the two engaging portions 31 is larger than the radial distance between the two circumferential flat portions 2112 and smaller than the radial distance between the two circumferential convex portions 2111.

As such, in the unlocked state, the joint segment 211 can pass through the joint via B, with the clip portion 31 located at the peripheral side planar portion 2112; in the process of switching from the unlocking state to the locking state, after the clamping portion 31 moves from the position of the circumferential flat portion 2112 to the position of the circumferential convex portion 2111, the joint section 211 cannot pass through the joint through hole B, so that the limiting purpose is achieved. In addition, the boss section 311 is pressed by the circumferential convex portion 2111, thereby providing an axial preload.

In the present disclosure, the hose connector 21 further includes a sleeve segment 213, the sleeve segment 213 is sleeved on the hose body 22, and the stop collar protruding segment 212 is located between the connector segment 211 and the sleeve segment 213.

It can be seen that the hose connector 21 is formed by a connector section 211, a stop collar projection 212 and a sleeve section 213, wherein the connector section 211 is intended to be connected to a brake hard tube connector, the stop collar projection 212 is intended to define the penetration depth of the hose connector 21, and the sleeve section 213 is intended to be fixedly connected to the hose body 22.

In the illustrated embodiment of the present disclosure, the hose connector 21 is a hexagonal connector, but is not limited thereto.
