Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more specifically, to a magnet bracket assembly, a braking system, and a vehicle. Background Technology
[0002] The braking system (also known as the braking system) is mainly used to help drivers slow down or even stop a moving vehicle. Currently, an electro-hydraulic assisted braking system has been designed specifically for the braking characteristics of electric vehicles and new energy vehicles: When the driver presses the brake pedal, the input push rod is displaced, and the magnet support assembly moves accordingly. The pedal travel sensor detects the magnet's displacement and sends this signal to the controller. The controller calculates the torque that the motor should generate, and the transmission device converts this torque into servo braking force. The servo braking force, together with the input push rod force generated by the pedal input, works in the master cylinder to convert into hydraulic pressure in the brake wheel cylinders to achieve braking.
[0003] In existing technology, the magnetic strip support assembly mainly consists of a support, magnetic strip 1, magnetic strip 2, and fasteners. Magnetic strip 1 and magnetic strip 2 need to be embedded into a pre-set mounting slot in the support, and then fastened to the support as a whole by fasteners to avoid detection errors caused by the magnetic strips loosening during vehicle operation. This solution has a large number of parts and high processing costs. Utility Model Content
[0004] The purpose of this application is to provide a magnet bracket assembly, a braking system, and a vehicle that can reduce the cost of the magnet bracket assembly.
[0005] The embodiments of this application are implemented as follows:
[0006] In one aspect of this application, a magnet bracket assembly is provided for use in a braking system, including a bracket, a first magnet, and a second magnet. The bracket has a groove for accommodating the first magnet and the second magnet. A folded edge is provided along the upper edge of the groove. The folded edge can be folded into the groove by a hot-melt process to abut against the upper sides of the first magnet and the second magnet respectively.
[0007] Optionally, as an implementable method, both the first magnet and the second magnet are bar magnets, the groove is a bar groove, and the first magnet and the second magnet are spaced apart along the extension direction of the bar groove.
[0008] Optionally, as an implementable method, a limiting protrusion is also provided in the groove to divide the strip groove into a first limiting groove and a second limiting groove. The first magnet is limited in the first limiting groove, and the second magnet is limited in the second limiting groove.
[0009] Optionally, as an implementable method, the folded edge includes a first folded edge and a second folded edge disposed on both sides of the groove, with the first folded edge and the second folded edge respectively abutting against both sides of the first magnet and the second magnet.
[0010] Optionally, as an implementable method, the first folded edge includes a first front folded edge and a first rear folded edge spaced apart, and the second folded edge includes a second front folded edge and a second rear folded edge spaced apart. After being folded, the first front folded edge and the second front folded edge respectively correspond to the middle of the first limiting groove, and after being folded, the first rear folded edge and the second rear folded edge respectively correspond to the middle of the first limiting groove.
[0011] Alternatively, as one possible implementation, the first front fold and the first rear fold are the same size, and the second front fold and the second rear fold are the same size.
[0012] Alternatively, as an implementable method, the folded edge and the bracket are integrally formed.
[0013] Alternatively, as one possible implementation, the first magnet and the second magnet are the same size.
[0014] In another aspect of this application, a braking system is provided, including a brake pedal assembly and a magnet bracket assembly as described in any of the above embodiments.
[0015] This application also provides a vehicle, including a frame and a braking system as described above.
[0016] The beneficial effects of the embodiments of this application include:
[0017] This application provides a magnet bracket assembly, a braking system, and a vehicle. The assembly, used in a braking system, includes a bracket, a first magnet, and a second magnet. The bracket has grooves for accommodating the first and second magnets. A folded edge is provided along the upper edge of the groove. The folded edge can be folded inwards into the groove via a heat-melting process to abut against the upper sides of the first and second magnets respectively. This eliminates the need for fasteners found in existing technologies, reducing the number of parts from four (bracket, magnet strip 1, magnet strip 2, and fastener) to three (bracket, first magnet, and second magnet), thus lowering production costs. The assembly process requires only two steps: "embedding the magnet" and "heat-melting the folded edge." Compared to the existing process of "embedding the magnet," "installing the fastener," and "tightening the fastener," this significantly improves production efficiency and better suits the needs of large-scale production. The folded edge is tightly held against the magnet via a heat-melting process, and the folded edge and bracket are an integrated structure, eliminating the risk of fastener loosening. This ensures stable fixation during long-term use, avoiding detection errors caused by loosening and improving the detection accuracy and reliability of the braking system.

[0026] Please refer to Figure 1 and Figure 2 This embodiment provides a magnet bracket assembly 100 for use in a braking system, including a bracket 110, a first magnet 120 and a second magnet 130. The bracket 110 has a groove 111 for accommodating the first magnet 120 and the second magnet 130. A folded edge 112 is provided on the upper edge of the groove 111. The folded edge 112 can be folded into the groove 111 by a hot-melt process so as to abut against the upper side of the first magnet 120 and the second magnet 130 respectively.
[0027] Specifically, the magnet bracket assembly 100 provided in this application is used in a braking system and includes a bracket 110, a first magnet 120, and a second magnet 130. The bracket 110 is an integrated structure made of engineering plastic with certain heat resistance and plasticity to ensure that the folded edge 112 can be folded in the subsequent hot-melt process and has sufficient strength after molding. The bracket 110 has a groove 111 for accommodating the first magnet 120 and the second magnet 130. The size of the groove 111 matches the shape of the first magnet 120 and the second magnet 130 to ensure that there is no obvious loosening after the magnet is inserted. Folded edges 112 are symmetrically arranged on the upper edge of the groove 111. The folded edges 112 are an extension structure integrally formed by the bracket 110. In the initial state, the folded edges 112 are perpendicular to the side wall of the groove 111 (i.e., the folded edges 112 extend horizontally outward). During assembly, the first magnet 120 and the second magnet 130 are respectively embedded in the groove 111. Then, the folded edge 112 is folded into the groove 111 by hot melting process, so that the folded edge 112 tightly abuts against the upper side of the first magnet 120 and the second magnet 130, thereby fixing the magnet in the groove 111 and realizing the integrated fixation of the bracket 110 and the magnet.
[0028] The magnet bracket assembly 100 provided in this application is used in a braking system and includes a bracket 110, a first magnet 120, and a second magnet 130. The bracket 110 has a groove 111 for accommodating the first magnet 120 and the second magnet 130. A folded edge 112 is provided along the upper edge of the groove 111. The folded edge 112 can be folded inward into the groove 111 by a hot-melt process, so as to abut against the upper side of the first magnet 120 and the second magnet 130 respectively. By eliminating the fasteners in the prior art, the number of parts is reduced from 4 (bracket 110, magnet 1, magnet 2, and fasteners) to 3 (bracket 110, first magnet 120, and second magnet 130), reducing production and processing costs. The assembly process only requires two steps: "embedding the magnet - hot-melting the folded edge 112". Compared with the process of "embedding the magnet - installing the fastener - tightening the fastener" in the prior art, the production efficiency is greatly improved, and it is more suitable for the needs of large-scale production. The folded edge 112 is tightly held against the magnet through a hot-melt process, and the folded edge 112 and the bracket 110 are an integrated structure, eliminating the risk of fastener loosening. It can maintain a stable fixing effect during long-term use, avoiding detection errors caused by loose fixing, and improving the detection accuracy and reliability of the brake system.
[0029] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the first magnet 120 and the second magnet 130 are both bar magnets, the groove 111 is a bar groove, and the first magnet 120 and the second magnet 130 are spaced apart along the extension direction of the bar groove.
[0030] Specifically, from a structural compatibility perspective, the shape of the bar magnet is highly matched to that of the bar groove, and the length direction of the bar magnet is consistent with the extension direction of the bar groove. This ensures that after the magnet is embedded in the bar groove, there is no excess gap in the length direction, reducing the risk of lateral displacement. Simultaneously, the first magnet 120 and the second magnet 130 are spaced apart along the extension direction of the bar groove, with a spacing of 5-10mm. This spacing avoids magnetic interference caused by the two magnets being too close, preventing magnetic field superposition from distorting the pedal travel sensor's detection signal. It also ensures that the two magnets are reasonably distributed within the limited space of the bar groove, adapting to the sensor's positional requirements for dual-magnet detection. This ensures that the sensor can accurately capture the displacement changes of the two magnets, thereby accurately feeding back pedal travel information.
[0031] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, a limiting protrusion 113 is also provided in the groove 111. The strip groove is divided into a first limiting groove 111 and a second limiting groove 111 by the limiting protrusion 113. The first magnet 120 is limited and disposed in the first limiting groove 111, and the second magnet 130 is limited and disposed in the second limiting groove 111.
[0032] Specifically, the limiting protrusion 113 is an integrally molded structure of the bracket 110, made of the same engineering plastic material as the bracket 110. The height of the protrusion is less than the depth of the strip groove, and both ends of the protrusion are tightly connected to the sidewalls of the strip groove, forming a non-removable partition structure. The dimensions of the first limiting groove 111 and the second limiting groove 111 are perfectly matched with the shapes of the first magnet 120 and the second magnet 130, respectively, ensuring that after the magnet is embedded in the corresponding limiting groove 111, there is no loose space in the horizontal direction (perpendicular to the extension direction of the strip groove), thus achieving precise positioning of the magnet.
[0033] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the folded edge 112 includes a first folded edge 112 and a second folded edge 112 arranged on both sides of the groove 111, and the first folded edge 112 and the second folded edge 112 respectively abut against both sides of the first magnet 120 and the second magnet 130.
[0034] Specifically, the first folded edge 112 and the second folded edge 112 are located on the left and right sides of the strip groove (perpendicular to the extension direction of the strip groove), respectively. Both are integral extension structures of the bracket 110. In the initial state, they extend outwards horizontally and perpendicularly to the side wall of the groove, with a length consistent with the length of the corresponding limiting groove 111. After hot-melt folding, the first folded edge 112 is tightly attached to the left side of the top surface of the first magnet 120 and the second magnet 130, and the second folded edge 112 is tightly attached to the right side of the top surface of the first magnet 120 and the second magnet 130, ensuring a stable support for the first magnet 120 and the second magnet 130 from both sides.
[0035] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the first folded edge 112 includes a first front folded edge 1121 and a first rear folded edge 1122 that are spaced apart, and the second folded edge 112 includes a second front folded edge 1123 and a second rear folded edge 1124 that are spaced apart. After being folded, the first front folded edge 1121 and the second front folded edge 1123 correspond to the middle of the first limiting groove 111, respectively. After being folded, the first rear folded edge 1122 and the second rear folded edge 1124 correspond to the middle of the first limiting groove 111, respectively.
[0036] Specifically, the first front fold 1121 and the first rear fold 1122 are spaced apart along the extension direction of the strip groove on the first fold 112, with the spacing greater than or equal to the length of the first limiting groove 111; the second front fold 1123 and the second rear fold 1124 are spaced apart on the second fold 112 at the same distance as the first fold 112. After folding, the first front fold 1121 and the first rear fold 1122 respectively cover the front half and the rear half of the middle of the first limiting groove 111, and the second front fold 1123 and the second rear fold 1124 are similarly arranged, forming a segmented abutment against the middle of the limiting groove 111. That is, after the first front fold 1121 and the second front fold 1123 are folded, they abut against the first magnet 120 in the first limiting groove 111, and after the first rear fold 1122 and the second rear fold 1124 are folded, they abut against the second magnet 130 in the first limiting groove 111.
[0037] Furthermore, the first front fold 1121 and the first rear fold 1122 are the same size, and the second front fold 1123 and the second rear fold 1124 are the same size.
[0038] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the folded edge 112 and the bracket 110 are integrally formed.
[0039] Specifically, the folded edge 112 and the bracket 110 are manufactured using a one-time injection molding process, using the same engineering plastic raw materials. During the injection molding process, the folded edge 112 and the bracket 110 are formed simultaneously, without any splicing gaps or connecting structures. After molding, the strength of the connection between the folded edge 112 and the bracket 110 is consistent with the strength of the main body of the bracket 110, ensuring that the folded edge 112 will not separate from the bracket 110 during hot-melt folding and long-term use.
[0040] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the first magnet 120 and the second magnet 130 are the same size.
[0041] Specifically, the length, width, and thickness of the first magnet 120 and the second magnet 130 are completely identical, and the magnetic properties parameters such as magnetic flux and coercivity of the two magnets are also consistent, ensuring that the magnetic field signal intensity received by the pedal travel sensor from the two magnets is the same during use, avoiding signal deviation caused by differences in magnet size or performance.
[0042] This application also discloses a braking system, including a brake pedal assembly and the magnet bracket assembly 100 from the foregoing embodiments. This braking system has the same structure and beneficial effects as the magnet bracket assembly 100 from the foregoing embodiments. The structure and beneficial effects of the magnet bracket assembly 100 have been described in detail in the foregoing embodiments and will not be repeated here.

This vehicle incorporates the same structure and beneficial effects as the magnet bracket assembly 100 described in the foregoing embodiments. The structure and beneficial effects of the magnet bracket assembly 100 have been described in detail in the foregoing embodiments and will not be repeated here.
[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
