Description

Technical Field

[0001] This utility model relates to the field of caliper assemblies, specifically a sensor assembly for calipers and a sensor assembly and caliper assembly having the sensor assembly. Background Technology

[0002] In existing EMB brake caliper technology solutions, the actuator controller structure needs to receive the clamping force signal at the wheel end and use the signal to perform the next action. This requires a force sensor to monitor the clamping force at the wheel end. The most commonly used force sensor is the ring force sensor, which is often placed inside the caliper body. When the brake is applied, the pressure signal output by the force sensor is transmitted to the controller, which controls the brake caliper to output the corresponding braking force for closed-loop control of the system.

[0003] In the existing technical solution CN220076355U, the force sensor is placed inside the clamp body, and the force sensor wiring harness is inserted from the outside through the wiring harness hole. After the male end of the force sensor wiring harness and the female end of the force sensor connector are assembled together vertically, the wiring harness is fixed by a wiring harness fixing bracket. The wires are externally fixed and sealed by a waterproof sealing head. The force sensor wiring harness is externally connected to the signal receiving device through a connector. This assembly structure and method largely solves the difficulty of the force sensor wire exit, but such a design structure still has certain risks. First, during the assembly process, since the force sensor is assembled from bottom to top in the clamp body... Then, the male end of the force sensor harness and the female end of the force sensor connector are assembled vertically. During assembly, due to the limited line of sight, the assembly of the male end of the force sensor harness and the female end of the force sensor connector is a blind insertion process. It is impossible to determine whether the axial assembly is in place through image detection or visual identification, which poses a risk of incomplete insertion. Secondly, since the force sensor harness and the force sensor connector are set in the vertical section in the existing technology, the distance between the upper end face of the force sensor assembly and the top of the clamp body is greater than the axial length of the connector. Therefore, the overall height of the system will be too high.

[0004] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the design of the existing caliper assembly or sensor components. Utility Model Content

[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0029] A caliper sensor assembly includes a sensor body 2, which is connected to a first connector 2b via a sensor harness 2a. The sensor assembly disclosed in this invention externally connects the first connector 2b via the sensor harness 2a. This arrangement not only facilitates subsequent insertion with a second connector 3a, but also prevents the first connector 2b from occupying the upper space of the sensor body 2, thereby reducing the axial space occupied by the first connector 2b during subsequent use and minimizing the reduction in the axial dimension of the caliper assembly.

[0030] The sensor assembly disclosed in this utility model is mainly applicable to caliper assemblies. The sensor assembly generally refers to the force sensor assembly in the caliper assembly.

[0031] The caliper sensor assembly of this invention mainly includes a sensor body 2, which is connected to a first connector 2b via a sensor harness 2a. The sensor body 2 is a force sensor. In this invention, the sensor body 2 is connected to the first connector 2b via the sensor harness 2a. The first connector 2b acts as a connector, facilitating the external wiring harness assembly during subsequent use. In addition, in this invention, the sensor harness 2a is essentially a wire. Based on the use of the sensor harness 2a, the first connector 2b is connected to the outside of the sensor body 2. This design avoids the first connector 2b being directly placed on the sensor body 2, thus preventing it from occupying the axial space of the caliper. Based on the above design, this invention can reduce the axial assembly space of the caliper assembly, thereby reducing the axial space of the entire caliper braking system. By setting the force sensor harness 2a and the force sensor connector in the oblique hole of the harness channel 1a of the caliper body 1, this design allows the distance between the upper end face of the force sensor assembly and the top position of the caliper body 1 to be unaffected by the connector length, allowing the caliper to have a lower axial height.

[0032] Furthermore, the sensor harness 2a described in this utility model is provided with a fixed harness bracket 5; the fixed harness bracket 5 facilitates the fixing of the sensor harness 2a and ensures the stability of the sensor harness 2a when installed on the caliper. In addition, the fixed harness bracket 5 is connected to the caliper body 1 of the caliper by screws.

[0033] A caliper sensor assembly includes a sensor component and a wiring harness assembly; the wiring harness assembly includes a wiring harness body 3, which is connected to a first connector 2b via a second connector 3a; the present invention facilitates the connection between the sensor component and the wiring harness assembly by using the first connector 2b and the second connector 3a, and also facilitates the connection between the sensor component and an external connector.

[0034] Furthermore, the caliper sensor assembly described in this utility model also includes a sealing component disposed on the sensor assembly and / or the wiring harness assembly; the sealing component is mainly provided to ensure the sealing of the connection between the sensor assembly and the caliper.

[0035] There are various types of seals in this invention. Theoretically, any seal that can meet the sealing requirements at the connection between the sensor assembly and / or wiring harness assembly and the caliper is sufficient.

[0036] In this invention, the sealing component can be disposed separately between the sensor assembly and the caliper or between the wiring harness assembly and the caliper; or it can be disposed simultaneously between the sensor assembly and the caliper and between the wiring harness assembly and the caliper.

[0037] The sealing assembly described in this utility model includes a sealing ring 2c disposed on the first connector 2b and / or a waterproof plug 3b disposed on the wire harness assembly; the sealing ring 2c is an annular structure, mainly sleeved on the first connector 2b, while the waterproof plug 3b can use the existing waterproof plug 3b structure, mainly to realize the installation connection of the waterproof plug 3b at the end of the wire harness through hole.

[0038] Furthermore, in this invention, a limiting mechanism is provided between the sensor assembly and the wiring harness assembly. The limiting mechanism includes a limiting boss 3d on the second connector 3a and a limiting hole 2d on the first connector 2b. The limiting boss 3d in the second connector 3a is connected to the limiting hole 2d on the first connector 2b. Through the mutual cooperation of the limiting boss 3d and the limiting hole 2d, this invention forms a hook structure, thereby ensuring the stability of the connection between the first connector 2b and the second connector 3a.

[0039] A caliper assembly includes a caliper body 1 with a cylinder bore inside; a wiring harness channel 1a is also provided on the caliper body 1; a caliper sensor assembly is provided on the caliper body 1; a first connector 2b is arranged in the wiring harness channel 1a; the caliper sensor assembly mainly includes a sensor body 2, which is connected to the first connector 2b via a sensor wiring harness 2a; the sensor body 2 is a force sensor, and in this invention, the sensor body 2 is connected to the first connector 2b via the sensor wiring harness 2a, with the first connector 2b acting as a connector to facilitate the external wiring harness assembly during subsequent use; the use of the sensor wiring harness 2a in this invention allows the first connector 2b to be connected to the outside of the sensor body 2. Based on this design, the first connector 2b can be avoided from being directly arranged on the sensor body 2, thus avoiding the first connector 2b occupying the axial space of the caliper, thereby reducing the axial assembly space of the caliper assembly and reducing the axial dimension of the entire caliper braking system.

[0040] In addition, in this invention, the first connector 2b and the second connector 3a in the sensor assembly are arranged in the wiring harness channel 1a of the caliper; by setting the sensor wiring harness 2a and the first connector 2b in the oblique hole of the wiring harness channel 1a of the caliper body 1, this design allows the distance between the upper end face of the force sensor assembly and the top position of the caliper body 1 to be unaffected by the connector length, and allows the caliper to have a lower axial height.

[0041] Furthermore, it can solve the risk of blind insertion during assembly, which poses a problem of incomplete insertion: In existing designs, due to visibility issues, the assembly of the male end of the force sensor harness 2a and the female end of the force sensor connector is a blind insertion process. It is impossible to determine whether the axial assembly is in place through image detection or visual identification, which poses a risk of incomplete insertion. This utility model uses the first connector 2b externally. In subsequent use, the first connector 2b and the second connector 3a can be assembled externally first, and then the connected first and second connectors can be assembled into the harness channel 1a. This not only facilitates the assembly of the sensor assembly and the harness assembly, but also effectively avoids the risk of incomplete insertion through the limiting mechanism.

[0042] Furthermore, in this utility model, the clamp body 1 is provided with a fixing mechanism for fixing the wire harness assembly; the setting of the fixing mechanism facilitates the installation and fixing of the wire harness assembly on the clamp body 1.

[0043] Specifically, the fixing mechanism in this utility model includes a fixing connector bracket 4 disposed on the wire harness assembly; the fixing connector bracket 4 is connected to the clamp body 1; the fixing connector bracket 4 is essentially a connecting frame structure, which facilitates the installation and fixing of the wire harness assembly on the clamp body 1.

[0044] In addition, the fixing mechanism described in this utility model also includes a fixing boss 1b disposed on the clamp body 1; the fixing connector bracket 4 is connected to the clamp body 1 through the fixing boss 1b; the fixing boss 1b is a connecting platform, and a fixing hole is provided on the fixing boss 1b to facilitate the installation and fixing of the fixing connector bracket 4 on the fixing boss 1b, thereby realizing the installation and fixing on the clamp body 1.

[0045] In the caliper sensor assembly described in this utility model, an external connector 3c is provided on the end of the wiring harness body 3 away from the second connector 3a; the external connector 3c is connected to the signal receiving device; based on this setting, the force sensor signal can be transmitted; facilitating subsequent detection and measurement of the force during braking.

[0046] specific:

[0047] The sensor assembly disclosed in this utility model mainly includes a sensor body 2, which is connected to a first connector 2b via a sensor wiring harness 2a.

[0048] The sensor assembly mainly includes sensor components and a wiring harness assembly; the wiring harness assembly includes a wiring harness body 3, which is connected to a first connector 2b via a second connector 3a.

[0049] The caliper assembly mainly includes a caliper body 1, which is also provided with a wire harness channel 1a; the sensor assembly is connected to the wire harness channel 1a, and the first connector 2b and the second connector 3a in the sensor assembly are arranged in the wire harness channel 1a.

[0050] Based on this configuration, it is equivalent to moving the connection position of the first connector 2b and the second connector 3a outward, thus preventing the first connector 2b and the second connector 3a from occupying the axial space of the caliper assembly.

[0051] In addition, in this utility model, the first connector 2b refers to the male end of the force sensor connector, and the second connector 3a refers to the female end of the force sensor connector.

[0052] A limiting boss 3d is provided on the female end of the force sensor harness 2a connector; a limiting hole 2d is provided on the male end of the force sensor connector; the limiting boss 3d and the limiting hole 2d of the male end of the force sensor connector are assembled to form a limiting structure.

[0053] A sealing ring 2c is provided on the male end of the sensor connector, and the sealing ring 2c forms a seal with the wire harness channel 1a.

[0054] The caliper assembly using the above-mentioned sensor assembly has the following advantages:

[0055] The axial assembly space of the sensor assembly is reduced, thereby reducing the axial space of the entire caliper assembly: By setting the sensor harness 2a and the first connector 2b in the oblique hole of the harness channel 1a, this design allows the distance between the upper end face of the sensor assembly and the top position of the caliper body 1 to be unaffected by the length of the first connector 2b or the second connector 3a, thereby enabling the caliper assembly to have a lower axial height.

[0056] In addition, this utility model, based on such a design, can solve the risk of blind insertion during assembly, which may result in incomplete insertion: In the existing design, due to line of sight, the assembly of the male and female ends of the sensor connector is a blind insertion process, and it is impossible to determine whether the axial assembly is in place through image detection or visual identification, which may result in incomplete insertion.

[0057] By setting the sensor harness 2a, the first connector 2b is brought out to the outside. In subsequent use, the first connector 2b and the second connector 3a can be assembled from the outside before being assembled into the harness channel 1a. This not only facilitates the assembly of the connectors, but also effectively avoids the risk of loose insertion through the limiting structure.

[0058] Improve the waterproof rating of the system: Add a sealing ring 2c to the first connector 2b to form a sealing structure with the wire harness channel 1a. Compared with the single use of waterproof plug 3b for sealing, this adds a waterproof structure and improves the waterproof rating of the system. Specific implementation examples:

[0060] Implementation Case 1:

[0061] The force sensor is placed inside the clamp body 1. The force sensor harness 2a is inserted from the outside through the harness through hole. After the male end of the force sensor harness 2a connector and the female end of the force sensor connector are assembled into one piece in the vertical direction, the harness is fixed by the harness fixing bracket. The harness is fixed and sealed by the waterproof sealing head. The force sensor harness 2a is connected to the signal receiving device through the external connector 3c. The force sensor signal is transmitted in this way.

[0062] Combined with appendix Figure 1-2 As can be seen, the sensor harness 2a is led out from the sensor body 2, and the other end of the sensor harness 2a is connected to the male end of the force sensor connector. One end of the force sensor harness 2a assembly is the female end of the force sensor harness 2a connector, and the other end is the external connector 3c of the force sensor harness 2a. The sealing plug is sleeved on the harness body 3. The male end of the force sensor connector and the female end of the force sensor harness 2a connector are respectively provided with a limiting hole 2d and a limiting boss 3d. The male end of the force sensor connector and the female end of the force sensor harness 2a connector are assembled and connected to form a connector. The limiting hole 2d and the limiting boss 3d form a limiting structure. The connector is arranged in the harness channel 1a on the clamp body 1. In addition, a sealing ring 2c is provided on the male end of the force sensor connector. The sealing ring 2c and the harness channel 1a form a sealing structure.

[0063] The wire harness bracket 5 is fixed to the clamp body 1 by the wire harness bracket screw 6, pressing the wire harness in place and preventing interference with the upper component; the wire harness channel 1a of the clamp body 1 is sealed and fixed to the wire by the waterproof plug 3b; the clamp body 1 is provided with a wire harness connector fixing boss 1b, and the external connector 3c is installed on the fixing boss 1b by the fixing connector bracket 4 and the fixing connector bracket screw 7. The external connector 3c is connected to the signal receiving device to realize the transmission of force sensor signal.

[0064] Combined with the appendix Figure 3-4During assembly, the sensor harness 2a is first inserted through the harness through hole on the caliper, and then the male end of the force sensor connector is connected to the female end of the force sensor harness 2a connector at the upper end of the caliper body 1. Compared with the blind insertion action in the prior art, this assembly can be visually identified, effectively eliminating the risk of misfitting. At the same time, this assembly method, which places the connector in the oblique hole of the harness channel 1a, can also reduce the distance between the upper end surface of the force sensor assembly and the top of the caliper body 1, thus reducing the overall height of the caliper system.

[0065] Obviously, the specific implementation of this utility model is not limited to the above-mentioned methods. Any non-substantial improvements made using the inventive concept and technical solution of this utility model are within the protection scope of this utility model.
