[0001] The utility model relates to the technical field of braking system, especially a connecting structure, and the utility model relates to a braking system with the connecting structure. BACKGROUND

[0002] With the development of intelligent and automatic driving, the by-wire hydraulic braking system is paid more and more attention, and the normal operation of the by-wire hydraulic braking system highly depends on the accurate real-time monitoring of various key parameters in the product, among which, the stable acquisition of signals such as pressure, displacement and motor rotation angle is particularly important. This requires that a stable and reliable signal transmission link be built between the matching sensor and the controller, that is, to ensure that the sensor can always maintain good contact with the controller, so as to ensure the continuous and stable output of the signal.

[0003] However, the contact scheme between the sensor and the controller widely used in the market at present mostly adopts the spring and contact point contact mode. Specifically, the elastic deformation of the spring is used to maintain the contact state between the two, so that the connection stability between the sensor and the controller is poor, which may cause instantaneous interruption or error information of signal transmission. SUMMARY

[0004] Therefore, the utility model aims at providing a connecting structure to improve the connection stability between the controller and the sensor.

[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0016] Further, the angle sensor is arranged on the side of the valve block opposite to the controller, and a through hole is arranged on the valve block.

[0017] The connecting terminal of the angle sensor passes through the through hole and abuts against the first elastic terminal.

[0018] Further, in the thickness direction of the valve block, the connecting terminal of the angle sensor is arranged flush with the end surface of the connecting terminal of the displacement sensor.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] The connecting structure can effectively guarantee the connection reliability and stability between the controller and the connecting terminal, can effectively reduce the risk of poor contact caused by vibration, and can improve the connection stability between the sensor and the controller.

[0022] In addition, the valve block is arranged on the controller, and the angle sensor is also arranged on the valve block, so that the integration of components can be improved; by arranging the convex ring on the shell of the controller, the first elastic terminal can be additionally protected, so that damage of the elastic terminal caused by external factors can be effectively avoided; meanwhile, the convex ring can guide and position the connecting terminal of the angle sensor, so that the connecting terminal of the angle sensor can abut against the first elastic terminal. By arranging the glue stealing groove in the convex ring on the shell of the controller, the overall weight of the shell of the controller can be effectively reduced, so that the machining cost can be reduced; meanwhile, the glue stealing groove can change the structure of the shell of the controller to some extent, so that the air circulation channel and the surface area can be increased.

Compared with single-point acquisition, more comprehensive displacement information can be obtained; and the strip-shaped convex is a unified support structure of the plurality of second elastic terminals, so that the plurality of second elastic terminals can move cooperatively and maintain a relatively stable positional relationship when subjected to external force, so that the connection stability between the displacement sensor and the controller can be further guaranteed, and the signal transmission can be ensured to be unaffected.

[0044] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.

[0045] In the description of the utility model, it should be noted that the terms "upper", "lower", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0046] In addition, in the description of the utility model, unless otherwise explicitly limited, the terms "mounting", "connecting", "connection", "connecting piece" should be understood broadly. For example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood in combination with the specific circumstances.

[0047] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0048] The contact scheme between the sensor and the controller 1 widely used in the market at the present stage mostly adopts the spring and contact point contact mode. The contact mode has many technical defects that cannot be ignored. On the one hand, it excessively depends on the compression amount and the spring force generated thereby of the spring itself to ensure the stability of the connection. This means that once the spring has performance degradation phenomena such as fatigue and aging in the long-term use process, the compression amount and the spring force that it can provide will certainly change, thereby directly affecting the contact tightness between the sensor and the controller 1, and ultimately leading to a great discount in the stability of the signal output.

[0049] On the other hand, in the actual operation of the vehicle, whether it is a regular vibration in daily driving, or a strong jolt encountered in complex road conditions, or even a long-term durability test, it is easy to cause the relative position between the spring and the contact to deviate, causing the contact between the two to loosen, and then the contact is poor. The occurrence of this poor contact problem will directly interfere with the accurate monitoring and real-time transmission of the internal key parameter signals of the brake system, and poses a serious threat to the reliability of the brake system.

[0050] To this end, the embodiment proposes a new connection structure for the connection between the controller 1 and the sensor, and the overall structure of the connection structure includes an elastic terminal provided on the controller 1 and a connection terminal provided on the sensor.

[0051] Among them, the elastic terminal is exposed relative to the controller 1, the connection terminal is recessed relative to the terminal shell, and a positioning groove is formed between the two, the free end of the elastic terminal is inserted into the positioning groove, and the elastic terminal is electrically connected with the connection terminal.

[0052] At this time, as set forth above, by recessing the connection terminal in the terminal shell and forming the positioning groove, and the free end of the elastic terminal can be inserted therein, the embodiment can improve the connection stability between the connection terminal and the elastic terminal of the sensor, and can effectively avoid the problem of relative displacement of the terminal caused by vehicle vibration, jolt and the like in the traditional connection mode, thereby achieving the effect of ensuring stable signal transmission.

[0053] Based on the above overall introduction, an exemplary structure of the connection structure of the embodiment is shown in Figures 1 to 8 .

[0054] Among them, the controller 1 is used for receiving, processing and responding to control signals, and the overall structure of the controller 1 is the same as the existing structure, and the shell mainly includes a controller cover and a controller shell body, and a circuit board is detachably fixed between the controller cover and the controller shell body, and the elastic terminal is connected with the circuit board. As for the remaining structural details of the controller 1, since there is no significant difference from the conventional setting in the prior art, they will not be described one by one here.

[0055] In addition, as a preferred embodiment, the elastic terminal of the embodiment is a spring provided on the circuit board of the controller 1. The spring structure is simple, easy to process and manufacture, and based on Figure 9 shown, it generally includes an upper connection portion and a lower abutting portion. Among them, the outer diameter of the connection portion is larger, which is used to connect with the circuit board, and the inner diameter of the abutting portion is smaller, which is beneficial to the butt joint connection with the sensor terminal.

[0056] In some embodiments, as Figure 1As shown in the controller 1 is also provided with a valve block 2, the sensor includes the angle sensor 4 provided on the valve block 2, the elastic terminal includes the first elastic terminal 101 provided on the controller 1. In addition, as shown in Figure 2 and Figure 8 As shown in the controller 1 is also provided with a valve block 2, the sensor includes the angle sensor 4 provided on the valve block 2, the elastic terminal includes the first elastic terminal 101 provided on the controller 1. In addition, as shown in

[0057] Wherein, the structure of the valve block 2 can refer to the prior art, and mainly includes a main block structure, a fluid passage provided in the inside, a mounting interface for rigid connection with the controller 1, the sensor, the electromagnetic valve and other components, a valve mounting hole and a sealing structure, and the specific structure can refer to the prior art. As a preferred embodiment, the convex ring 102 is annular, and the first elastic terminal 101 is six spaced apart in the convex ring 102. Here, for the sake of distinction, the positioning groove formed on the angle sensor 4 is called "first positioning groove 301", and correspondingly, as shown in Figure 6 The first positioning groove 301 of the angle sensor 4 is also six spaced apart.

[0058] It needs to be emphasized that the shape of the convex ring 102 is not limited to a circle, and it can be flexibly changed according to the diversified needs in the actual application scene, or any suitable shape such as ellipse or polygon. Similarly, the number of the first elastic terminal 101 and the connecting terminal can be adjusted, and they can be increased or decreased according to the actual needs of the brake system in different vehicle models and different working conditions, so as to ensure that the entire brake system always maintains the best performance.

[0059] In addition, as shown in Figure 1 and Figure 2 The angle sensor 4 is installed on the side of the valve block 2 opposite to the controller 1, and a through hole is provided on the valve block 2. The connecting terminal of the angle sensor 4 passes through the through hole and abuts against the first elastic terminal 101. Among them, the chip part of the angle sensor 4 is installed on the side of the valve block 2 opposite to the controller 1 by clamping, and the connecting terminal of the angle sensor 4 passes through the through hole.

[0060] This clamping design not only fully considers the simplicity of installation, ensures that the positioning and fixation of the angle sensor 4 can be quickly completed in the production and assembly process, but also takes into account the stability, so that the chip can be firmly attached to the valve block 2 even in various complex vibration and bumping conditions during vehicle operation, providing protection for data acquisition. As for other structural details of the angle sensor 4, since there is no significant difference between it and the conventional structure in the existing mature technology, it is not necessary to repeat here, and the clamping structure can also adopt the conventional structure.

[0061] Furthermore, as a further implementation form, in combination with Figure 4 and Figure 8 As shown in FIG. 1 1, a plurality of glue-stealing grooves 103 are arranged on the shell of the controller 1, and the glue-stealing grooves 103 are located in the convex ring 102. By arranging the glue-stealing grooves 103, the overall weight of the shell of the controller 1 can be effectively reduced. At the same time, the glue-stealing grooves 103 can change the structure of the shell of the controller 1, increase the air circulation channel and surface area, and thus effectively improve the heat dissipation condition of the controller 1 and improve the reliability and stability of the operation of the controller 1. In addition, the number and arrangement of the glue-stealing grooves 103 are not limited to Figure 4 As shown in FIG. 1 1, a plurality of glue-stealing grooves 103 are arranged on the shell of the controller 1, and the glue-stealing grooves 103 are located in the convex ring 102. By arranging the glue-stealing grooves 103, the overall weight of the shell of the controller 1 can be effectively reduced. At the same time, the glue-stealing grooves 103 can change the structure of the shell of the controller 1, increase the air circulation channel and surface area, and thus effectively improve the heat dissipation condition of the controller 1 and improve the reliability and stability of the operation of the controller 1. In addition, the number and arrangement of the glue-stealing grooves 103 are not limited to

[0062] In some embodiments, in combination with Figure 2 , Figure 3 and Figure 5 and Figure 6 As shown in FIG. 1 1, a plurality of glue-stealing grooves 103 are arranged on the shell of the controller 1, and the glue-stealing grooves 103 are located in the convex ring 102. By arranging the glue-stealing grooves 103, the overall weight of the shell of the controller 1 can be effectively reduced. At the same time, the glue-stealing grooves 103 can change the structure of the shell of the controller 1, increase the air circulation channel and surface area, and thus effectively improve the heat dissipation condition of the controller 1 and improve the reliability and stability of the operation of the controller 1. In addition, the number and arrangement of the glue-stealing grooves 103 are not limited to

[0063] By directly arranging the displacement sensor 3 on the valve block 2 and closely combining with the controller 1, the space utilization of the brake system is more efficient, the additional wiring and installation structure requirements are reduced, and the entire system is more compact. In addition, the arrangement of the groove 106 can provide a certain protection for the second elastic terminal 104. By recessing into the interior of the shell of the controller 1, the groove 106 can effectively block the intrusion of foreign matters from the outside, so as to avoid that these impurities adhere to the elastic terminal and affect the electrical performance. By arranging the second elastic terminal 104 in the convex 105, the second elastic terminal 104 is constrained in the axial and radial directions, so as to avoid excessive displacement or shaking during the vibration and bumping of the vehicle, and to facilitate ensuring that the second elastic terminal 104 can always maintain good contact with the connecting terminal of the displacement sensor 3 and stably transmit signals, so as to provide reliable displacement monitoring data for the brake system.

[0064] Furthermore, the protrusion 105 is elongated, and multiple second elastic terminals 104 are threaded through it, spaced apart along the length of the protrusion 105. By arranging the multiple second elastic terminals 104 spaced apart along the length of the elongated structure of the protrusion 105, the displacement sensor 3 can establish connections with the controller 1 at multiple different locations, achieving multi-point signal acquisition. Compared to single-point acquisition, this method can obtain more comprehensive and detailed displacement information.

[0065] In addition, the elongated protrusion 105 provides a unified and stable support structure for the multiple second elastic terminals 104. Since all the elastic terminals are mounted on the same protrusion 105, they can move in coordination and maintain a relatively stable positional relationship when subjected to external forces such as vehicle vibration and bumps. This further ensures the connection stability between the displacement sensor 3 and the controller 1 and ensures that signal transmission is not affected.

[0066] like Figure 5 As shown in the preferred embodiment, the groove 106 is elongated, and three protrusions 105 are spaced apart along the length of the groove 106, with two second elastic terminals 104 passing through each protrusion 105. For ease of distinction, the positioning groove formed on the displacement sensor 3 is referred to as the "second positioning groove 401," corresponding to... Figure 9 As shown, the second positioning groove 401 on the displacement sensor 3 consists of six grooves, each corresponding to a second elastic terminal 104. It should be noted that the geometry of the grooves 106 and protrusions 105 can be adaptively adjusted according to the diverse needs of actual application scenarios. Whether changed to an ellipse, polygon, or other irregular shape, it can be adjusted as needed. Similarly, the specific number of second elastic terminals 104 and protrusions 105 is not fixed and can be flexibly increased or decreased according to the braking system characteristics and performance optimization direction of different vehicle models.

[0067] In some embodiments, the end faces of the connection terminals of the angle sensor 4 and the displacement sensor 3 are flush in the thickness direction of the valve block 2. This arrangement results in a more regular structure at the connection between the sensor and the controller 1, facilitating the unified planning of the protection and fixing structures of the connection terminals, reducing the variety of components, and further improving the system's integration and maintainability. Furthermore, since the angle sensor 4 and the displacement sensor 3 typically need to transmit critical signals to the controller 1 simultaneously during braking system operation, aligning their connection terminal end faces makes the signal transmission paths more spatially close and parallel, reducing potential transmission delay differences caused by variations in signal paths.

[0068] In addition, the flush end face arrangement also helps to reduce signal interference. Since the two sensor connection terminals are relatively regular in space, the uneven changes in electric field and magnetic field caused by the uneven terminals are avoided, thereby reducing the possibility of mutual interference between signals and ensuring the purity and accuracy of signal transmission, laying a foundation for stable and reliable operation of the braking system.

[0069] As shown in Figure 6 As a specific embodiment, the valve block 2 is provided with a mounting groove 201 on the side facing the controller 1, and the mounting groove 201 is arranged in the displacement sensor 3. Moreover, one end of the displacement sensor 3 is embedded in the mounting groove 201 and fixed in the mounting groove 201 by a fastener. By arranging the mounting groove 201 in the displacement sensor 3, the close fit between the displacement sensor 3 and the valve block 2 can be ensured, and the problem of inaccurate signal acquisition caused by sensor shaking and displacement during vehicle operation can be effectively avoided.

[0070] In addition, embedding the displacement sensor 3 in the mounting groove 201 can also buffer the impact force from the outside to a certain extent. When the vehicle is subjected to extreme conditions such as collision and severe vibration, the mounting groove 201 can absorb part of the impact force, reduce the pressure directly borne by the displacement sensor 3, avoid damage to the displacement sensor 3 due to excessive impact, and protect the integrity and reliability of the sensor. The fastener is specifically a screw or bolt passing through the displacement sensor 3.

[0071] It can be understood that in addition to only arranging the displacement sensor 3 and the angle sensor 4 on the valve block 2, other types of sensors such as pressure sensors can also be further arranged, and the connection structure between the sensors and the controller 1 can also adopt the above connection structure.

[0072] The connection structure of the embodiment can effectively ensure the connection stability between the displacement sensor 3 and the angle sensor 4 and the controller 1, facilitate continuous transmission of signals, and enable the braking system to maintain original performance after the vehicle is subjected to large vibration.

[0073] In addition, the embodiment also relates to a braking system, and the controller 1 and the sensors in the braking system are connected through the above connection structure. In addition, other structures of the braking system are the same as those of the prior art, and will not be described here.

[0074] The braking system of the embodiment connects the controller 1 and the sensors in the braking system through the above connection structure, which facilitates to improve the connection firmness between the sensors and the controller 1, can effectively avoid signal interruption or errors caused by poor connection, greatly improves the reliability and stability of the braking system, and facilitates to improve driving safety.

[0075] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
