Description

Technical Field

[0001] This utility model relates to the field of sealing structures, specifically a sealing plug structure and a caliper assembly having the sealing plug structure. Background Technology

[0002] In numerous industrial equipment, piping systems, and various mechanical devices, sealing performance has always been a crucial factor.

[0003] Whether it's the transport of liquids or gases, or the sealing and isolation of a specific space, a reliable sealing structure is required to ensure the normal operation and safety of the system.

[0004] Traditional sealing plug structures have many problems in practical applications.

[0005] On the one hand, the sealing effect is often difficult to achieve ideally, and leaks are prone to occur. This not only leads to the waste of resources, such as liquid leakage and gas escape, but may also cause safety hazards.

[0006] On the other hand, the traditional structure is more complicated to operate during installation and fixing, requiring additional tools and cumbersome steps, which not only increases installation costs but also reduces work efficiency.

[0007] Moreover, some fixing methods lack stability and are prone to loosening after long-term use or under harsh working conditions such as vibration, which in turn affects the sealing performance.

[0008] Meanwhile, during wire harness installation, the wire harness often needs to pass through the housing or a certain component. The connection between the wire harness and the corresponding component usually needs to be sealed by a sealing structure. The traditional sealing method is to connect with a sealing ring or a sealing sleeve. The traditional connection method is simple, and the sealing ring is not secure enough. Therefore, the connection between the wire harness and the component will loosen after a long period of use.

[0009] In addition, in existing EMB brake caliper technology solutions, the 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. The controller controls the brake caliper to output the corresponding braking force for closed-loop control of the system. For example, patent CN220076355U proposes a method to transmit the signal from the force sensor through a wire harness and connect it to an external connector through the caliper body. However, the wire harness passing through the caliper body will damage the caliper seal, so a water plug is needed to seal the wire harness and the caliper body.

[0010] The existing water plug has a complex overall structure and requires many operating procedures, which is not conducive to its practical use.

[0011] In addition, when assembling the existing water plug, the fixing screw needs to be installed on the clamp body first, and then the rubber plug and locking nut need to be installed on the fixing screw. Due to space constraints, the screw tightening assembly process is difficult.

[0012] In addition, existing water plugs have two waterproof structures: a sealing ring and a rubber plug. This presents two risks of failure for the system.

[0013] Furthermore, the existing sealing structure is assembled by stacking multiple parts, resulting in a relatively high protrusion of the waterproof module, which makes the overall structure of the brake caliper not compact enough.

[0014] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the design of the existing water plug structure. Utility Model Content

[0046] 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.

[0047] This utility model discloses a sealing plug structure 3b, including a sealing mechanism and a fixing mechanism; the sealing mechanism includes a sealing plug 3b; the fixing mechanism includes a fixing screw 3a; the fixing screw 3a can be used to install and fix the sealing plug 3b; the sealing plug structure 3b disclosed in this utility model can be installed and fixed by only the fixing screw 3a. This design facilitates the subsequent use and installation of the sealing plug structure 3b. At the same time, the sealing plug 3b and the fixing screw 3a cooperate with each other. The sealing plug 3b achieves sealing at the connection of the corresponding parts, while the fixing screw 3a can fix the sealing plug 3b on the corresponding parts, avoiding the problem of easy movement or displacement of traditional single sealing elements.

[0048] The sealing plug 3b structure 3 disclosed in this utility model mainly serves a sealing function.

[0049] It can be applied to pipes, containers, shells, and other component structures.

[0050] Meanwhile, the sealing plug structure 3b disclosed in this utility model is mainly used to achieve a sealing operation at the connection between the wire harness and the corresponding part when the wire harness passes through a certain part.

[0051] The sealing plug 3b is the core component for achieving the sealing function.

[0052] They are usually made of materials with a certain degree of elasticity and strength, such as rubber, silicone, and polytetrafluoroethylene (PTFE).

[0053] Its shape can be cylindrical, conical, etc., depending on the shape of the part that needs to be sealed.

[0054] Fixing screw 3a: Used to fix the sealing plug 3b to the part that needs to be sealed.

[0055] Fixing screws 3a are generally made of metal, such as stainless steel or carbon steel, and have good strength and corrosion resistance.

[0056] Under normal circumstances, the fixing screw 3a of this utility model is used in conjunction with the corresponding part to install and fix the sealing plug 3b; the fixing screw 3a is connected to the corresponding part to ensure that the sealing plug 3b is stably in the position to be sealed.

[0057] Furthermore, in this utility model, the fixing screw 3a includes a screw body with a screw center hole 3a3; the sealing plug 3b includes a plug body with a through hole; the screw center hole 3a3 communicates with the through hole; this utility model facilitates the threading of the wire harness on the sealing plug 3b structure 3 by providing the screw center hole 3a3 and the through hole; this utility model requires the screw center hole 3a3 to be connected to the through hole; it also facilitates the subsequent threading of the wire harness through the above two components.

[0058] Additionally, it should be noted that the screw body and the plug body mentioned above are a single general term in this utility model.

[0059] At the same time, based on the above requirements, this utility model also facilitates the subsequent use of the two together, making it convenient for the fixing screw 3a to be fitted onto the sealing plug 3b.

[0060] In this utility model, the screw body is the main structure for fixing the screw 3a. It is usually made of metal, such as stainless steel or carbon steel, and has sufficient strength and corrosion resistance.

[0061] The screw's central hole 3a3 is a through hole structure that penetrates the screw body.

[0062] Its main functions include:

[0063] Wiring harness assembly insertion: This facilitates the passing of the wiring harness assembly through the fixing screw 3a, ensuring smooth installation of the wiring harness assembly.

[0064] Matching with sealing plug 3b: The screw's central hole 3a3 is connected to the through hole of sealing plug 3b to fix sealing plug 3b and ensure a tight fit between sealing plug 3b and fixing screw 3a.

[0065] The plug body is the main structure of the sealing plug 3b, and is usually made of materials with a certain degree of elasticity and strength, such as rubber, silicone, polytetrafluoroethylene, etc.

[0066] The through hole is a through-hole structure that penetrates the plug body.

[0067] Its main functions include:

[0068] Wiring harness assembly connection: facilitates the wiring harness assembly to pass through the sealing plug 3b, ensuring that the wiring harness assembly can be installed smoothly.

[0069] The through hole is connected to the screw's central hole 3a3 and is used to cooperate with the fixing screw 3a to fix and seal the sealing plug 3b. The fixing screw 3a can be sleeved on the plug body through the screw's central hole 3a3 to achieve mutual limiting and positioning between the sealing plug 3b and the fixing screw 3a, ensuring accurate cooperation between the two during installation.

[0070] Furthermore, in this utility model, the screw body includes a limiting block 3a4 and a connecting post 3a2 disposed on the limiting block 3a4; in this utility model, the limiting block 3a4 is part of the screw body and is used to limit the position of the sealing plug 3b, ensuring that the sealing plug 3b will not move excessively during or after installation, thereby ensuring the reliability of the seal.

[0071] The limiting block 3a4 has a large cross-sectional area, providing sufficient support and limiting functions.

[0072] The connecting post 3a2 is set on the limiting block 3a4 and is used to fix the connection between the fixing screw 3a and the connected parts, so as to finally achieve the fastening of the fixing screw 3a on the corresponding parts. At the same time, the connecting post 3a2 of this utility model also cooperates with the sealing plug 3b; the connecting post 3a2 presses against the sealing plug 3b, which better ensures the accuracy of the installation position of the sealing plug 3b and the sealing performance of the connection between the sealing plug 3b and the parts.

[0073] The cross-sectional area of ​​the connecting post 3a2 is no greater than the cross-sectional area of ​​the limiting block 3a4. This design ensures that the connecting post 3a2 provides the connecting function without affecting the limiting function of the limiting block 3a4.

[0074] Meanwhile, the cross-sectional area of ​​the connecting column 3a2 mentioned here is not greater than the cross-sectional area of ​​the limiting block 3a4; it should be noted that the cross-section here is based on the attached... Figure 2 and attached Figure 3 Based on this, the longitudinal section is perpendicular to the paper surface; that is, the vertical section. The main purpose of this is to make the screw body form a convex structure, which facilitates connection and also plays a good role in limiting movement.

[0075] Furthermore, in this utility model, the plug body includes a plug body 3b3; one end of the plug body 3b3 is provided with a pressing boss 3b2; the vertical cross-sectional area of ​​the pressing boss 3b2 is not less than the vertical cross-sectional area of ​​the plug body 3b3; in this utility model, the plug body is the main structure of the sealing plug 3b; and the plug body 3b3 is the main part of the plug body, used to realize the function of connection and positioning.

[0076] The clamping boss 3b2 is set at one end of the plug body 3b3. Generally, the plug body 3b3 is only provided with a clamping boss 3b2 at one end. If there are other requirements, it is also feasible to provide a clamping boss 3b2 at both ends. The specific design scheme can be modified according to the actual working conditions.

[0077] The clamping boss 3b2 of this utility model mainly serves a sealing function. By pressing the clamping boss 3b2 against the corresponding hole on the part, the sealing effect of the sealing plug 3b is guaranteed.

[0078] In this invention, the vertical cross-sectional area of ​​the pressing boss 3b2 is not less than the vertical cross-sectional area of ​​the plug body 3b3. This design makes the pressing boss 3b2 and the plug body 3b3 form a stepped platform structure. This setting facilitates the pressing of the fixing screw 3a against the sealing plug 3b during subsequent use, and can better ensure the accuracy of the density plug installation position.

[0079] Furthermore, in this utility model, the screw body is fitted onto the plug body through the screw's central hole 3a3; the connecting post 3a2 in the screw body presses against the clamping boss 3b2 in the plug body; based on this arrangement, the screw body is essentially fitted onto the plug body, while the connecting post 3a2 on the screw body presses against the clamping boss 3b2. The limiting block 3a4 and the connecting post 3a2 are both fitted onto the plug body 3b3. The end of the connecting post 3a2 away from the limiting block 3a4 presses against and adheres to the clamping boss 3b2. In subsequent use, the clamping boss 3b2 is arranged in the corresponding wire hole of the part, and the connecting post 3a2 in the screw body is fixedly connected to the end of the hole of the corresponding part. After the screw body is installed and fixed on the part, the screw body may cooperate with the part to squeeze the clamping boss 3b2, thereby achieving the fixed installation of the sealing plug 3b in the wire harness through hole 1a.

[0080] In addition, in this utility model, the screw body may not be sleeved on the plug body. The screw body can directly press against the side of the plug body and be connected to the part through the screw body; thereby realizing the compression and fixation of the plug body in the corresponding hole of the part.

[0081] Furthermore, in this utility model, the outer surface of the pressing boss 3b2 is an arc-shaped surface or a sloped surface; in this utility model, the pressing boss 3b2 can form different shapes by different outer surfaces, and different structures of pressing boss 3b2 can be selected according to actual needs; thus optimizing the stability of the contact between the sealing plug 3b and the part.

[0082] When the outer surface 3b1 of the clamping boss 3b2 is an arc-shaped surface, the outer surface 3b1 of the clamping boss 3b2 as a whole has a spherical structure.

[0083] When the outer surface 3b1 of the clamping boss 3b2 is inclined, the clamping boss 3b2 as a whole has a frustum-shaped structure.

[0084] When the sealing plug 3b structure 3 of this utility model is applied to a caliper, the specific implementation scheme is as follows:

That is, when the wire harness assembly passes through the wire harness through hole 1a on the caliper 1, the plug structure 3 can seal the end of the wire harness through hole 1a, thereby achieving the sealing of the wire passage of the caliper 1.

[0087] The plug structure 3 disclosed in this utility model mainly includes a sealing mechanism and a fixing mechanism for fixing the sealing mechanism; the sealing mechanism is mainly a sealing element, and the fixing mechanism is a locking element. In subsequent use, the fixing mechanism drives the sealing mechanism to connect to the clamp 1, thereby realizing the sealing operation of the sealing mechanism at the connection between the wire harness through hole 1a and the wire harness assembly.

The fixing screw 3a and the wire harness through hole 1a can be an interference fit or a screw connection as described below. Of course, in actual use, a snap-fit ​​connection or other connection methods can also be used. The essence is that as long as a stable fixed connection between the fixing screw 3a and the caliper 1 can be achieved, it is acceptable.

Its basic function is to facilitate the subsequent threading of the wire harness assembly, that is, to facilitate the connection and installation of the fixing screw 3a on the wire harness assembly. Another function is that it can be fitted onto the sealing plug 3b as needed to facilitate the mutual limiting and positioning between the sealing plug 3b and the fixing screw 3a.

[0091] In addition, the sealing plug 3b described in this utility model includes a plug body, which is the main structure of the sealing plug 3b. The plug body is provided with a through hole.

In this utility model, the screw body is inserted into the wire harness through hole 1a through the connecting post 3a2. The size of the limiting block 3a4 is larger than the size of the connecting post 3a2, that is, the limiting block 3a4 is protruding on the connecting post 3a2. The limiting block 3a4 plays a blocking role. Based on this setting, the limiting block 3a4 can prevent the screw body from being over-inserted into the wire harness through hole 1a.

In order to facilitate the subsequent connection of the plug structure 3, the wire harness through hole 1a includes a straight section and a threaded section, and a sealing mating end face is formed at the connection between the threaded section and the straight section; this facilitates the subsequent cooperation with the pressing boss 3b2, and thus the mutual compression to achieve the compression and fixation of the sealing plug 3b.

[0118] Similarly, in this invention, the outer surface of the pressing boss 3b2 can be a conical end face or a spherical end face; the specific choice can be made according to the actual working conditions. In addition, in order to ensure the fit, the corresponding sealing mating end face in the wire harness channel in this invention can also be a conical end face or a spherical end face.

[0124] Reduced failure modes: This invention completes the sealing function using only one rubber plug; reducing the failure area of ​​the rubber plug.

[0125] The fixing screw 3a of this utility model can be manufactured by cold heading process, which has the advantage of low cost compared with the existing machining process.

[0126] Implementation Case 1:

[0127] As shown in the attached figure: the force signal transmission method of the force sensor in the caliper 1 is as follows: the force sensor is placed inside the caliper body and is connected to a wire harness assembly. The wire harness assembly passes through the wire harness through hole 1a on the caliper 1 and is close to one end of the force sensor 6. One end of the wire harness assembly can be fixed to the caliper body 1 by the wire harness fixing bracket 4.

[0128] Specifically, the wire harness fixing bracket 4 is fixed to the clamp body 1 by screws 5, and the wires in the wire harness assembly are fixed and sealed by the plug structure 3. The force sensor wire harness 2 is connected to the signal receiving device through the external connector 2a, wherein the external connector 2a is connected to the connector fixing bracket 7, and the connector fixing bracket 7 is fixed to the clamp body by screws 8.

[0129] The caliper 1 plug structure 3 disclosed in this utility model mainly includes a fixing screw 3a and a sealing plug 3b. Both the fixing screw 3a and the sealing plug 3b are sleeved on the wire harness in the wire harness assembly. In subsequent use, they are inserted into the end of the wire harness channel on the caliper 1.

[0130] Specifically, in this utility model, the plug structure 3 mainly includes a fixing screw 3a and a sealing plug 3b; the fixing screw 3a includes a limiting block 3a4 and a connecting column 3a2, the vertical cross-sectional dimension of the limiting block 3a4 is larger than the vertical cross-sectional dimension of the connecting column 3a2, and the sealing plug 3b includes a plug body 3b3 and a pressing boss 3b2.

[0131] Among them, the plane of the connecting post 3a2 near the clamping boss 3b2 is the clamping plane 3a1, the outer side of the connecting post 3a2 has a threaded section, and the screw body is provided with a threaded intermediate hole.

[0132] The sealing plug 3b includes a plug body, which includes a plug body 3b3 and a clamping boss 3b2 disposed on the plug body 3b3.

[0133] The clamping boss 3b2 is used in conjunction with the clamping plane 3a1.

[0134] In this design, the outer surface 3b1 of the clamping boss 3b2 is an inclined surface, meaning that the clamping boss 3b2 has a frustum-shaped structure.

[0135] In this utility model, the wire harness through hole 1a mainly includes a connecting hole 1a-1 and a connecting hole 1a-2; the connecting hole 1a-2 includes a first connecting hole 1a2 and a second connecting hole 1a1, the first connecting hole 1a2 is connected to the connecting hole 1a-1 through the second connecting hole 1a1; the inner wall of the second connecting hole 1a1 is a sealing mating end face; the inner wall of the first connecting hole 1a2 is provided with an internal thread to form a threaded section.

[0136] During assembly, the wire harness assembly passes through the sealing plug 3b, which is placed inside the wire harness through hole 1a. Then, the wire harness assembly passes through the middle hole of the fixing screw 3a, which is screwed into the connecting hole 1a-2. As the fixing screw 3a is tightened, the pressing plane 3a1 of the fixing screw 3a contacts and presses against the pressing boss 3b2. At this time, as the sealing plug 3b is pressed, the sealing mating end face contacts and presses against the beveled end of the fixing screw 3a plug. As the beveled end of the fixing screw 3a plug is pressed, under the action of the conical surface, the head of the fixing screw 3a plug will shrink towards the middle and be held by the wire harness assembly to form a seal between the wire harness assembly and the sealing plug. Compared with the sealing water plug structure 3 in the prior art, the sealing water plug structure 3 of this utility model has fewer parts and a more compact structure.

[0137] Implementation Case 2:

[0138] This embodiment is similar in main structure to Embodiment 1. In this embodiment, the outer side 3b1 of the pressing boss 3b2 in the sealing plug 3b is a spherical structure. The mating sealing end faces can be mutually mating spherical structures. After assembly, the waterproof sealing effect required by this utility model can also be achieved. The relevant technical principles here are the same as those in the previous embodiment, and will not be repeated here.

[0139] 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.
