Description

Technical Field

[0001] The present invention relates to the field of sealing structures, in particular to a sealing plug structure and a caliper assembly having the sealing plug structure. Background Art

[0002] Sealing performance is always a crucial link in many industrial equipment, piping systems and various mechanical devices.

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

[0004] The traditional sealing plug structure has many problems in practical application.

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

[0006] On the other hand, during the installation and fixing process, the operation of the traditional structure is relatively complicated, requiring additional tools and tedious steps, which not only increases the installation cost but also reduces work efficiency.

[0007] Moreover, some fixing methods are not stable enough and are prone to loosening after long-term use or under harsh working conditions such as vibration, thereby affecting the sealing performance.

[0008] At the same time, at present, when the wiring harness is installed, the wiring harness often needs to pass through the shell or a certain part. This is because the connection between the wiring harness and the corresponding part generally requires a sealing structure. The traditional sealing method is to connect through a sealing ring or a sealing sleeve. The traditional connection method is single, and the sealing ring fixing method is not strong enough, so the connection between the wiring harness and the part will become loose after long-term use.

[0009] In addition, in the existing EMB brake caliper technical solution, the execution controller structure needs to receive the signal of the clamping force of the wheel end and perform the next action through the signal. In this way, a force sensor is needed to monitor the clamping force of the wheel end. The most commonly used force sensor is the annular force sensor, which is often arranged in the caliper body. When the brake is applied, the pressure signal output by the force sensor is transmitted to the controller, and the controller controls the brake caliper to output the corresponding braking force for the closed-loop control of the system. For example, in patent CN220076355U, a method is proposed to transmit the signal from the force sensor through the wiring harness and pass it through the caliper body to connect it to an external connector. The wiring harness passing through the caliper body will destroy the caliper body seal, so a water plug is required to achieve the sealing of the wiring harness and the caliper body.

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

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

[0012] In addition, the existing water plug has two waterproof structures: a sealing ring and a rubber plug, which poses two risks of failure to the system.

[0013] Furthermore, the existing sealing structure is assembled by stacking multiple parts, resulting in a high protrusion height 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. Summary of the Invention

[0046] The specific implementation of the present invention will be further explained in detail below by describing the best embodiment with reference to the accompanying drawings.

[0047] The present invention discloses a sealing plug 3b structure 3, 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 3b structure 3 disclosed by the present invention; the sealing plug 3b can be installed and fixed only by the fixing screw 3a, such a setting facilitates the subsequent use and installation of the sealing plug 3b structure 3, and at the same time, the sealing plug 3b and the fixing screw 3a of the present invention cooperate with each other, the sealing plug 3b realizes sealing at the connection between corresponding parts, and the fixing screw 3a can realize fixed installation of the sealing plug 3b on the corresponding part, avoiding the problem that traditional single sealing components are prone to movement or displacement.

[0048] The sealing plug 3b structure 3 disclosed in the present invention mainly plays a sealing role.

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

[0050] At the same time, the sealing plug 3b structure 3 disclosed in the present invention is mainly used to achieve a sealing operation at the connection between the wiring harness and the corresponding part when the wiring harness passes through a certain part.

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

[0052] It is usually made of materials with certain elasticity and strength, such as rubber, silicone, polytetrafluoroethylene (PTFE), etc.

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

[0054] Fixing screw 3a: used to fix the sealing plug 3b at the position requiring sealing.

[0055] The fixing screw 3a is generally made of metal, such as stainless steel, carbon steel, etc., and has good strength and corrosion resistance.

[0056] In general, the fixing screw 3a of the present invention cooperates with corresponding parts to achieve the installation and fixation of the sealing plug 3b; the fixing screw 3a is connected to the corresponding parts to ensure that the sealing plug 3b is stably located in the position to be sealed.

[0057] Furthermore, in the present invention, the fixing screw 3a includes a screw body, and the screw body is provided with a screw middle hole 3a3; the sealing plug 3b includes a plug body, and the plug body is provided with a through hole; the screw middle hole 3a3 is connected with the through hole; the present invention facilitates the connection of the wiring harness on the sealing plug 3b structure 3 through the setting of the screw middle hole 3a3 and the through hole; the present invention requires that the screw middle hole 3a3 is connected with the through hole; it also facilitates the subsequent passage of the wiring harness through the above two components.

[0058] In addition, it should be noted that the screw body and the plug body mentioned above in the present invention are a general term.

[0059] At the same time, based on the above requirements, the present invention also facilitates the subsequent coordinated use of the two, and facilitates the sleeve connection of the fixing screw 3a on the sealing plug 3b.

[0060] In the present invention, the screw body is the main structure of the fixing screw 3a, which is usually made of metal, such as stainless steel, carbon steel, etc., and has sufficient strength and corrosion resistance.

[0061] The middle hole 3a3 of the screw is a through hole structure that passes through the screw body.

[0062] Its main functions include:

[0063] Threading of the wiring harness assembly: facilitate the wiring harness assembly to pass through the fixing screw 3a to ensure that the wiring harness assembly can be installed smoothly.

[0064] Matching with the sealing plug 3b: The middle hole 3a3 of the screw is connected with the through hole of the sealing plug 3b, which is used to fix the sealing plug 3b and ensure a tight match between the sealing plug 3b and the fixing screw 3a.

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

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

[0067] Its main functions include:

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

[0069] Coordination with the fixing screw 3a: The through hole is connected to the middle hole 3a3 of the screw, and is used to cooperate with the fixing screw 3a to achieve the fixation and sealing of the sealing plug 3b; the fixing screw 3a can be sleeved on the plug body through the middle hole 3a3 of the screw to achieve mutual limitation and positioning between the sealing plug 3b and the fixing screw 3a, ensuring accurate cooperation between the two during the installation process.

[0070] Furthermore, in the present invention, the screw body includes a limit block 3a4 and a connecting column 3a2 arranged on the limit block 3a4; in the present invention, the limit block 3a4 is a part of the screw body, which is used to limit the position of the sealing plug 3b, ensuring that the sealing plug 3b does not move excessively during or after installation, thereby ensuring the reliability of the seal.

[0071] The cross-sectional area of the limiting block 3a4 is relatively large, providing sufficient support and limiting functions.

[0072] The connecting column 3a2 is set on the limit block 3a4, and is used to fix the subsequent connection between the fixing screw 3a and the connected parts, and finally realize the fastening of the fixing screw 3a on the corresponding part. At the same time, the connecting column 3a2 of the present invention also cooperates with the sealing plug 3b; the connecting column 3a2 presses the sealing plug 3b to better ensure the accuracy of the installation position of the sealing plug 3b and the sealing of the connection between the sealing plug 3b and the parts.

[0073] The cross-sectional area of the connecting column 3a2 is not greater than the cross-sectional area of the limiting block 3a4. This design allows the connecting column 3a2 to provide a connecting function without affecting the limiting function of the limiting block 3a4.

[0074] At the same time, the cross-sectional area of the connecting column 3a2 is not greater than the cross-sectional area of the limit block 3a4; Figure 2 and attached Figure 3 As a reference, the longitudinal section is perpendicular to the paper surface; that is, the vertical section; the above is mainly to make the screw body form a convex structure, which is convenient for connection and can also play a good limiting role.

[0075] Furthermore, in the present invention, the plug body includes a plug main body 3b3; a clamping boss 3b2 is provided at one end of the plug main body 3b3; the vertical cross-sectional area of the clamping boss 3b2 is not less than the vertical cross-sectional area of the plug main body 3b3; in the present invention, the plug body is the main structure of the sealing plug 3b; and the plug main body 3b3 is the main part of the plug body, which is used to achieve the functions of connection and positioning.

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

[0077] The pressing boss 3b2 of the present invention mainly plays a sealing role. The sealing effect of the sealing plug 3b is ensured by the pressing boss 3b2 pressing against the corresponding hole on the part.

[0078] In the present invention, the vertical cross-sectional area of the clamping boss 3b2 is not less than the vertical cross-sectional area of the plug body 3b3. This design enables the clamping boss 3b2 and the plug body 3b3 to form a stepped structure. This arrangement facilitates the subsequent use of the fixing screw 3a to press against the sealing plug 3b, and can better ensure the accuracy of the installation position of the density plug.

[0079] Furthermore, in the present invention, the screw body is sleeved on the plug body through the middle hole 3a3 of the screw; the connecting column 3a2 in the screw body is pressed against the clamping boss 3b2 in the plug body; based on such a setting, the screw body is equivalent to being sleeved on the plug body, and at the same time, the connecting column 3a2 on the screw body is pressed against the clamping boss 3b2, and the limit block 3a4 and the connecting column 3a2 are both sleeved on the plug body 3b3 at the same time, and the end of the connecting column 3a2 away from the limit block 3a4 is pressed and fitted on the clamping boss 3b2. During subsequent use, the clamping boss 3b2 is arranged in the corresponding threading hole of the part, and the connecting column 3a2 in the subsequent screw body is fixedly connected to the hole end of the corresponding part. After the screw body is installed and fixed on the part, the screw body may cooperate with the part to realize the extrusion of the clamping boss 3b2, thereby realizing the fixed installation of the sealing plug 3b in the wiring harness through-hole 1a.

[0080] In addition, in the present invention, the screw body may not be sleeved on the plug body. The screw body may be directly pressed against the side of the plug body and connected to the part through the screw body; thereby achieving the extrusion and fixation of the plug body in the corresponding hole of the part.

[0081] Furthermore, in the present invention, the outer side surface of the clamping boss 3b2 is an arc-shaped surface or an inclined surface; in the present invention, the clamping boss 3b2 can form clamping bosses 3b2 of different shapes through different outer side surfaces, and clamping boss 3b2 structures of different structures can be selected according to actual needs; and the stability of the contact between the sealing plug 3b and the parts is optimized.

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

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

[0125] The fixing screw 3a of the present invention can be manufactured by cold heading process, which has the advantage of low cost compared with the machining process in the prior art.

[0126] Implementation Case 1:

[0127] As shown in the accompanying drawings: the force signal transmission method of the force sensor in the caliper 1 is: the force sensor is placed inside the caliper body, and the force sensor is connected to a wiring harness assembly. The wiring harness assembly passes through the wiring harness through-hole 1a on the caliper 1, close to one end of the force sensor 6, and one end of the wiring harness assembly can be fixed to the caliper body 1 through the wiring harness fixing bracket 4.

[0128] Specifically, the wiring harness fixing bracket 4 is fixed to the clamp body of the clamp body 1 by screws 5, and the wires in the wiring harness assembly are fixed and sealed externally by a plug structure 3. The force sensor wiring harness 2 is connected to the signal receiving device through an 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 plug structure 3 of the caliper 1 disclosed in the present invention mainly includes a fixing screw 3a and a sealing plug 3b. The fixing screw 3a and the sealing plug 3b are both sleeved on the wiring harness in the wiring harness assembly, and are plugged into the end of the wiring harness channel on the caliper 1 when used subsequently.

[0130] Specifically, in the present invention, the plug structure 3 mainly includes a fixing screw 3a and a sealing plug 3b; the fixing screw 3a includes a limit block 3a4 and a connecting column 3a2, the vertical cross-sectional dimension of the limit 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 clamping boss 3b2.

[0131] Among them, the plane of the connecting column 3a2 close to one end of the pressing boss 3b2 is the pressing plane 3a1, the outer side surface of the connecting column 3a2 has a threaded section, and a threaded middle hole is provided on the screw body.

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

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

[0134] In this solution, the outer side surface 3b1 of the pressing boss 3b2 is an inclined surface, that is, the pressing boss 3b2 is a frustum-shaped structure.

[0135] In the present invention, the wiring 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, and 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 wiring harness assembly passes through the sealing plug 3b, and the sealing plug 3b is placed in the wiring harness through-hole 1a. Then the wiring harness assembly also passes through the middle hole of the fixing screw 3a, and the fixing screw 3a is screwed into the connecting hole 1a-2. As the fixing screw 3a is tightened, the clamping plane 3a1 of the fixing screw 3a contacts and presses the clamping boss 3b2. At this time, as the sealing plug 3b is compressed, the sealing mating end face contacts and presses the inclined end of the fixing screw 3a plug. As the inclined end of the fixing screw 3a plug is compressed, under the action of the conical surface, the head of the fixing screw 3a plug will shrink toward the middle and be tightly embraced by the wiring harness assembly to form a seal between the wiring harness assembly. Compared with the sealing water plug structure 3 in the prior art, the sealing water plug structure 3 of the present invention has fewer parts and a more compact structure.

After assembly is completed, the waterproof sealing effect required by the present invention can also be achieved. The relevant technical principles here are consistent with the previous implementation case and will not be repeated here.

[0139] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods.
