[0033] like Figure 1-2 and Figure 4 As shown, the brake spring sheet 100 according to the embodiment of the utility model includes: a first substrate 10 and a second substrate 20 .

[0034] Among them, the first substrate 10 is fixedly connected to the second substrate 20, and the second substrate 20 includes a main body 21 and a plurality of hook portions 22, and the plurality of hook portions 22 are arranged at intervals on the main body 21, and at least one of the plurality of hook portions 22 is quickly connected to the brake 200 to limit the movement of the brake spring sheet 100 relative to the brake 200 along a first direction, and at least one of the plurality of hook portions 22 is quickly connected to the brake 200 to limit the movement of the brake spring sheet 100 relative to the brake 200 along a second direction, and the first direction is different from the second direction.

[0035] Specifically, the brake spring sheet 100 of the present application is arranged on the brake 200, and the top of the brake 200 has a connecting piece 220. The brake spring sheet 100 is arranged on the top of the brake 200. The brake 200 also has a fixing piece. Exemplarily, the fixing piece can be a rib in the middle part of the caliper body. The brake spring sheet 100 is constructed as a split structure. The second substrate 20 is connected to both the connecting piece 220 and the fixing piece, and to the first substrate 10. The second substrate 20 can play a role in fixing the brake spring sheet 100 to the brake 200.

[0036] It should be noted that the brake 200 includes two brake discs 210 that are spaced apart and arranged opposite to each other, the two ends of the first substrate 10 are respectively connected to the tops of the two brake discs 210, the first substrate 10 is fixedly connected to the second substrate 20, the setting direction of the second substrate 20 is perpendicular to the setting direction of the first substrate 10, the second substrate 20 is fixedly installed above the first substrate 10, at least one hook portion 22 in the second substrate 20 is quickly connected to the connecting member 220, and at least one hook portion 22 that is quickly connected to the connecting member 220 limits the movement of the second substrate 20 relative to the brake 200 along the first direction, and the first direction is Figure 4 The direction indicated by the arrow A is the width direction of the brake disc 210; at least one hook portion 22 in the second substrate 20 is quickly connected to the fixing member, and at least one hook portion 22 quickly connected to the fixing member limits the movement of the second substrate 20 relative to the brake 200 along the second direction. The second direction is Figure 4 The direction indicated by the middle arrow B is the length direction of the brake disc 210 .

[0037] According to the brake spring piece 100 of the embodiment of the utility model, the second substrate 20 is configured to include a plurality of hook portions 22, so that at least one of the plurality of hook portions 22 is quickly connected with the brake 200 to limit the movement of the brake spring piece 100 relative to the brake 200 along a first direction, and at least one of the plurality of hook portions 22 is quickly connected with the brake 200 to limit the movement of the spring piece relative to the brake 200 along a second direction. The position of the spring piece can be limited from at least two directions to fix the position of the brake spring piece 100 and improve the stability of the brake spring piece 100. The connection between the brake spring piece 100 and the brake 200 is achieved by quickly connecting the two hook portions 22 with the brake 200. The structure is simple and the connection is convenient and quick.

[0038] It is understandable that one hook portion 22 can be quickly connected to the brake 200, which can limit the movement of the brake spring sheet 100 relative to the brake 200 along the first direction, and the other hook portion 22 can be quickly connected to the brake 200, which can limit the movement of the brake spring sheet 100 relative to the brake 200 along the second direction and the third direction, and the first direction, the second direction and the third direction are all different.

[0039] like Figure 1 As shown, in some embodiments, the hook portion 22 includes a connecting portion 224 and a clamping portion 225, and the clamping portion 225 is connected to the body 21 through the connecting portion 224. The body 21 of the second substrate 20 is a plate-like structure extending obliquely, and the hook portion 22 can be arranged on the body 21 or at the end of the body 21. The hook portion 22 is bent relative to the body 21. The hook portion 22 includes a connecting portion 224 and a clamping portion 225, one end of the connecting portion 224 is connected to the body 21, and the other end of the connecting portion 224 is connected to the clamping portion 225. In this way, the hook portion 22 has a simple structure, is convenient to set up, and is convenient to connect with the body 21, which reduces the difficulty of manufacturing.

[0040] like Figure 1 As shown, the connecting portion 224 is connected to the body 21 via an arc plate 226 , and / or the connecting portion 224 is connected to the clamping portion 225 via an arc plate 226 .

[0041] It should be noted that each hook portion 22 has a connecting portion 224 and a clamping portion 225. The hook portion 22 is arranged on the main body 21. The clamping portion 225 is connected to the main body 21 through the connecting portion 224. One end of the connecting portion 224 is connected to the main body 21 through an arc plate 226. The other end of the connecting portion 224 extends upward or downward relative to the main body 21 in a first direction. One end of the clamping portion 225 is connected to the other end of the connecting portion 224 through an arc plate 226. The other end of the clamping portion 225 extends in a direction opposite to the connecting portion 224, so that the connecting portion 224 and the clamping portion 225 form a hook-shaped structure.

[0042] With such arrangement, the structure of the hook portion 22 is simple, and it is convenient to arrange a plurality of hook portions 22 on the main body 21. The main body 21 and the connecting portion 224, as well as the connecting portion 224 and the snap-fitting portion 225 are connected via arc plates 226. On the one hand, the appearance of sharp corners can be avoided, so that the hook portion 22 and the brake 200 are more securely connected, and sharp corners at the connection are avoided to scratch the brake 200; on the other hand, the connecting portion 224 and the snap-fitting portion 225 can form a matching area connected to the brake 200, thereby increasing the contact area with the brake 200 and improving the stability of the matching between the hook portion 22 and the brake 200.

[0043] like Figure 1-2 and Figure 4 As shown, specifically, the plurality of hook portions 22 include: a first hook portion 221 and a second hook portion 222 , the first hook portion 221 is snap-connected to the brake 200 , and / or the second hook portion 222 is concave-convexly matched to the brake 200 .

[0044] The first hook portion 221 and the second hook portion 222 are both connected to the brake 200, and there are various ways of connection. For example, the first hook portion 221 can be connected to the brake 200 by snap-fitting, connected to the brake 200 by concave-convex fitting, or connected to the brake 200 by other connecting methods. Similarly, the second hook portion 222 can be connected to the brake 200 by snap-fitting, connected to the brake 200 by concave-convex fitting, or connected to the brake 200 by other connecting methods.

[0045] like Figure 1 As shown, the first hook portion 221 and the second hook portion 222 are respectively located at the two ends of the body 21, wherein the positions of the two ends of the body 21 are determined by taking the length dimension of the body 21 as the midpoint. It should be noted that a plurality of hook portions 22 are arranged on the body 21, and the plurality of hook portions 22 can be arranged on the body 21 or at the ends of the body 21. In one embodiment, the first hook portion 221 and the second hook portion 222 are respectively arranged at the two ends of the body 21, and the two ends of the body 21 are the two ends in the length direction of the body 21. In this way, the first hook portion 221 and the second hook portion 222 are respectively arranged at the two ends of the body 21, and the first hook portion 221 is snap-connected with the brake 200, and the second hook portion 222 is concave-convexly matched with the brake 200, so as to facilitate the connection between the two and the brake 200, and can improve the stability of the connection between the first hook portion 221, the second hook portion 222 and the brake 200. It can be understood that, as Figure 4As shown, the first hook portion 221 is snap-connected with the connecting member 220 of the brake 200 to limit the movement of the brake spring sheet 100 and the brake 200 along the second direction, and the second hook portion 222 is concave-convexly matched with the brake 200 to limit the movement of the brake spring sheet 100 and the brake 200 along the first direction. The first hook portion 221 is snap-connected with the connecting member 220 of the brake 200, and can also limit the movement of the brake spring sheet 100 and the brake 200 along the second direction and the third direction at the same time.

[0046] Furthermore, the first hook portion 221 and the second hook portion 222 are located on the same side in the thickness direction of the body 21. Figure 1 The direction indicated by arrow C is exemplary, as Figure 1 As shown, the first hook portion 221 and the second hook portion 222 are bent downward relative to the body 21, and in the first direction, the second hook portion 222 is located above the first hook portion 221. This arrangement facilitates quick connection between the first hook portion 221 and the second hook portion 222 and the brake 200, and can improve the stability of the connection between the first hook portion 221 and the brake 200, and the second hook portion 222 and the brake 200.

[0047] Specifically, the plurality of hook portions 22 include a third hook portion 223 . Along the thickness direction of the body 21 , the third hook portion 223 is located at a side of the body 21 away from the first hook portion 221 .

[0048] like Figure 1-Figure 2 and Figure 4 As shown, in some embodiments, the body 21 is provided with a third hook portion 223, which is provided in the thickness direction of the body 21, and its setting direction is opposite to the setting direction of the first hook portion 221 and the second hook portion 222. One end of the third hook portion 223 is connected to the body 21, and the other end is bent toward a side away from the first hook portion 221 and the second hook portion 222. The third hook portion 223 can be used to fix the alarm harness to ensure the stability of the alarm harness and ensure that its function is normal. The clamping portion 225 of the third hook portion 223 is a free end, which is spaced a certain distance from the body 21, so as to fix the alarm harness in the third hook portion 223.

[0049] like Figure 1 and Figure 4 As shown, further, a baffle 2211 is provided in the first hook portion 221, one end of the baffle 2211 is connected to the connecting portion 224 of the first hook portion 221, and the other end of the baffle 2211 extends toward the clamping portion 225 of the first hook portion 221, or, one end of the baffle 2211 is connected to the clamping portion 225 of the first hook portion 221, and the other end of the baffle 2211 extends toward the connecting portion 224 of the first hook portion 221.

[0050] like Figure 1 and Figure 4 As shown, specifically, the first hook portion 221 is snap-connected with the brake 200, and the brake 200 is fitted between the clamping portion 225 of the first hook portion 221 and the connecting portion 224. The blocking piece 2211 can be formed on the clamping portion 225 or the connecting portion 224 of the first hook portion 221. If it is formed on the clamping portion 225, the other end of the blocking piece 2211 extends toward the connecting portion 224; if it is formed on the connecting portion 224, the other end of the blocking piece 2211 extends toward the clamping portion 225. The other end of the baffle 2211 is a free end, which is spaced a certain distance from the arc plate 226 between the clamping portion 225 and the connecting portion 224. When the first hook portion 221 is quickly connected with the brake 200, the baffle 2211 is engaged above the brake 200. By arranging the baffle 2211 on the first hook portion 221, the spring sheet can be restricted from moving relative to the brake 200 along the first direction and the second direction, thereby further enhancing the stability of the connection between the second substrate 20 and the connecting member 220.

[0051] In addition, the blocking piece 2211 of the first hook portion 221 can be formed by punching. Of course, it can also be formed by other processing methods, and can also be a separate component connected to the first hook portion 221; the formation method of the third hook portion 223 can be the same as the formation method of the blocking piece 2211.

[0052] like Figure 2 and Figure 3 As shown, in some embodiments, the first substrate 10 has a mounting surface 11, the mounting surface 11 is fixedly connected to the second substrate 20, and the mounting surface 11 is tilted to at least partially fit with the body 21. The tilt angle of the mounting surface 11 is consistent with the tilt angle of the body 21. The second substrate 20 is arranged above the first substrate 10, and the mounting surface 11 of the first substrate 10 cooperates with the body 21. Since the body 21 is tilted, the mounting surface 11 is also tilted to cooperate with the installation of the second substrate 20, and the tilt angle of the mounting surface 11 is consistent with the tilt angle of the body 21. In this way, it is convenient to install the second substrate 20 with the first substrate 10, and the mounting surface 11 is tilted, and its tilt angle is consistent with the tilt angle of the body 21, which facilitates the installation of the second substrate 20 with the first substrate 10, so as to ensure the tightness of the connection between the first substrate 10 and the second substrate 20, thereby improving the reliability of the spring sheet 100 for the brake.

[0053] In addition, if Figure 2 and Figure 4As shown, the second substrate 20 and the first substrate 10 are riveted together by the fasteners 30, and the brake spring leaf 100 is set as a split structure. By riveting the first substrate 10 and the second substrate 20 that are separately set together by the fasteners 30, it is possible to avoid cross-sectional mutations and gaps at the connection position between the first substrate 10 and the second substrate 20, and to avoid problems such as fatigue deformation of the brake spring leaf 100 caused by stress concentration, thereby improving the service life of the brake spring leaf 100.

[0054] The brake 200 according to the embodiment of the utility model comprises a brake disc 210 and a brake spring sheet 100 according to any one of the above embodiments. There are two brake spring sheets 100 , which are fixed at both ends of the brake disc 210 .

[0055] Specifically, if Figure 4 As shown, two brake spring sheets 100 are installed on the top of the brake 200, and the two brake spring sheets 100 are arranged at intervals along the second direction. The brake 200 includes two spaced and opposite brake discs 210, and the two brake spring sheets 100 are symmetrically distributed at both ends of the brake disc 210. The second hook portions 222 of the two brake spring sheets 100 are opposite to each other, and the first hook portions 221 of the two brake spring sheets 100 are far away from each other. The two second hook portions 222 are both matched with the fixing member, and the two first hook portions 221 are both matched with the connecting member 220 to fix the two ends of the brake spring sheets 100 on the brake 200, thereby realizing the connection between the brake spring sheets 100 and the brake 200.

[0056] The vehicle according to the utility model includes the brake 200 in the above-mentioned embodiment. By arranging the brake spring sheet 100 of this structure on the brake 200, the position of the spring sheet can be limited from at least two directions to fix the position of the brake spring sheet 100, thereby improving the stability of the brake spring sheet 100, thereby limiting the brake 200 and assisting its return.
