Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, and more specifically, relates to an integrated cylinder wiring harness assembly, mounting structure, and vehicle. Background Technology

[0002] Integrated cylinder-through wiring harness assembly is a component used to realize electrical connections between internal and external equipment such as engines and transmissions. It integrates wiring harnesses and cylinder-through components, and has advantages such as improved connection reliability and simplified installation process. It is widely used in the automotive field, especially in new energy vehicles.

[0003] However, in the design and manufacturing of new energy vehicles, electrical connections need to adapt to complex vehicle structures, especially in cases involving penetration into cylinders (such as the cylinder-shaped housings of battery packs and powertrain components). Traditional connectors struggle to balance the sealing requirements after penetration with reliable electrical connections, leading to issues such as seal failure causing liquid or gas leaks that affect vehicle performance, or insufficient connector structural strength and poor conductivity stability. These limitations fail to meet the high safety, reliability, and durability requirements of new energy vehicles. Therefore, it is necessary to design an integrated penetration connector specifically adapted to the cylinder penetration scenario in new energy vehicles, optimizing its structure to address the aforementioned pain points.

[0004] To address the aforementioned issues, a search revealed that patent application CN212908886U discloses an integrated oil-cooled powertrain wiring harness direct-connection cylinder-mounted resolver integrated structure. This structure includes a cylinder-mounted device body, with epoxy resin installed inside the body via the wiring harness. The epoxy resin is poured into the interior of the cylinder-mounted device body. The left side of the wiring harness is connected to the middle right side of a first connector, and the right side of the wiring harness wraps around the outer wall of a second connector, with a resolver fixed to the right side of the second connector. Patent application CN218569324U discloses a cylinder-mounted wiring harness assembly, including a through-hole connector. Two symmetrically distributed sealing grooves are formed at one end of the outer wall of the through-hole connector, and rubber sealing sleeves are fitted onto these grooves to ensure airtightness at the through-hole. A wire is located at the end of the through-hole connector near the rubber sealing sleeve. In this invention, the through-hole connector is inserted into the cylinder body and connects to an external terminal. The sealing effect is improved by applying epoxy resin to the external seal when the through-hole connector is connected to the wire.

[0005] However, in the two patents mentioned above, the wire harness and terminal connection are subsequently injection molded into the cylinder insert or inserted into the corresponding hole slot in the cylinder insert, and the connection between the wire harness and the conductive pin is exposed on the outside, resulting in poor airtightness. Summary of the Invention

[0006] 1. The problem to be solved

[0007] To address the technical problems existing in the prior art, this utility model provides an integrated through-cylinder wiring harness assembly, which improves the airtightness at the connection between the wiring harness and the conductive pin.

[0008] Another objective of this invention is to provide an installation structure having the aforementioned integrated cylinder wiring harness assembly.

[0009] Another objective of this invention is to provide a vehicle having the aforementioned mounting structure.

[0010] 2. Technical Solution

[0011] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0012] The first aspect of this utility model provides an integrated cylinder-through wiring harness assembly, including a cylinder-through connector, a rotary transformer, and a temperature sensor, wherein the cylinder-through connector includes:

[0013] The main body shell is made of insulating material and has a configuration suitable for cylinder mounting; the main body shell is provided with mounting ears for mounting and fixing, which can fix the main body shell inside the cylinder;

[0014] One end of the main body shell is provided with a plug-in part, which contains at least eight conductive pins arranged in an orderly manner to achieve circuit connection; the other end of the main body shell is provided with a sealing part, which faces the inner side of the cylinder and forms a sealing cavity, and the conductive pins extend into the sealing cavity.

[0015] A sealing end plate placed in the sealing cavity has a groove on its upper part and a through hole inside along the length center axis of the sealing end plate, through which the conductive pin passes.

[0016] A sealing layer made of adhesive is filled in the through holes and grooves. Preferably, the outer end face of the sealing layer is flush with the end face of the sealing part, so that the adhesive can seal the connection between the wire harness and the conductive pins, effectively preventing airtightness problems. Two conductive pins pass through the sealing layer and are connected to the temperature sensor. At least a portion of the ends of the remaining conductive pins extend to the bottom of the groove flush with it, or exceed the bottom but not the top surface of the groove; preferably, they extend 0.2 to 0.5 mm beyond the bottom. Six of the remaining conductive pins are connected to the rotary transformer via the wire harness. The aforementioned "at least a portion" refers to the end of at least one conductive pin.

[0017] According to any embodiment of the first aspect of the present invention, the groove is square or rectangular in shape, which can provide a wider injection port for dispensing, thereby improving the efficiency of dispensing.

[0020] According to any embodiment of the first aspect of the present invention, the through hole and the conductive pin are fitted with a gap, allowing the gap between them to be filled with a sealing layer formed by adhesive, thereby further achieving a sealing effect. The adhesive can fill downwards along the gap until it is completely filled, which reduces the amount of adhesive used; on the other hand, the adhesive completely covers the conductive pin from top to bottom, resulting in a good sealing effect.

[0021] According to any embodiment of the first aspect of the present invention, the number of through holes is matched with the number of conductive pins, wherein the sealing end plate can separate several conductive pins to avoid short circuits in the conductive pins.

[0022] According to any embodiment of the first aspect of the present invention, a sealing element is provided in the middle of the main body shell to achieve sealing on both sides of the cylinder body after cylinder installation. The sealing effect is achieved by the rubber ring directly contacting the cylinder body to prevent liquid and gas leakage.

[0023] According to any embodiment of the first aspect of the present invention, the sealing part is provided with at least one relief hole, so that when the glue is overfilled, some of the glue can overflow from the relief hole.

[0024] According to any embodiment of the first aspect of the present invention, the conductive pin is made of copper or copper alloy and its surface is treated with anti-oxidation, such as tin plating or silver plating, to improve conductivity stability and corrosion resistance. The conductive pin is arranged in a matrix or linear pattern in the plug part to ensure accurate docking with the adapter plug.

[0025] According to any embodiment of the first aspect of the present invention, the sealing element is a sealing ring made of rubber or silicone, with a cross-section that is circular, rectangular or irregular, adapted to the sealing requirements after the main body shell and cylinder are installed. The sealing ring is interference-fitted with the main body shell or installed by means of a slot or other structure to ensure that the sealing element is stable and the sealing is reliable after installation.

[0026] According to any embodiment of the first aspect of the present invention, the main body shell is made of a high-temperature resistant and impact-resistant insulating material, such as PBT, PA66, PPS, etc., to adapt to the high temperature and vibration environment of the cylinder. The mounting holes of the mounting ears are round, oblong, or other shapes to accommodate mounting screws or bolts, which facilitates use in different assembly scenarios.

[0027] The second aspect of this utility model provides an integrated through-cylinder wiring harness assembly mounting structure, including a cylinder body and the integrated through-cylinder wiring harness assembly described in the first aspect. A mounting hole is provided on the cylinder body, and the through-cylinder connector is detachably mounted at the mounting hole of the cylinder body. The rotary transformer and temperature sensor are disposed inside the cylinder body.

[0028] A third aspect of this invention provides a vehicle having the integrated cylinder-through wiring harness assembly mounting structure described in the second aspect above, wherein the integrated cylinder-through wiring harness assembly mounting structure is mounted on the vehicle's cylinder block. In the integrated oil-cooled powertrain of new energy vehicles, the integrated cylinder-through wiring harness assembly of this invention enables the connection between internal electrical components and external control units.

[0049] The following detailed description of exemplary embodiments of the present invention refers to the accompanying drawings, which form part of the description, illustrating exemplary embodiments in which the present invention may be implemented. Although these exemplary embodiments have been described in sufficient detail to enable those skilled in the art to implement the present invention, it should be understood that other embodiments may be implemented and various changes may be made to the present invention without departing from the spirit and scope thereof. The more detailed description of embodiments of the present invention below is not intended to limit the scope of the claimed invention, but is merely illustrative and does not limit the description of the features and characteristics of the invention, in order to suggest the best mode for carrying out the invention and sufficient to enable those skilled in the art to implement it. Therefore, the scope of the present invention is defined only by the appended claims.

[0050] The following detailed description and exemplary embodiments of the present invention can be better understood in conjunction with the accompanying drawings, wherein the elements and features of the present invention are identified by reference numerals.

[0051] This embodiment takes an oil-cooled motor in a new energy vehicle as an example. Correspondingly, the cylinder refers to the motor housing, and the wiring harness can connect the resolver and temperature sensor inside the motor cylinder. In the integrated oil-cooled powertrain of a new energy vehicle, the integrated through-cylinder wiring harness assembly of this embodiment can realize the connection between internal electrical components and external control units.

[0052] Example 1

[0053] like Figure 1 As shown, the integrated cylinder-through wiring harness assembly of this utility model includes a cylinder-through connector, a rotary transformer 400, and a temperature sensor 500, combined with... Figures 1 to 8 As shown, the cylinder connector includes a main body housing 100, a sealing end plate 200, and a sealing layer 300. In this embodiment, taking an oil-cooled motor from a new energy vehicle as an example, the cylinder body 700 refers to the motor housing.

[0054] Among them, such as Figures 5 to 8 As shown, the sealing end plate 200 is placed in the sealing cavity 131. The sealing end plate 200 is made of PA66, PC, PPS or PEEK material. A groove 210 is provided on the upper part of the sealing end plate 200. Twelve through holes 220 are opened inside the sealing end plate 200 along the length center axis. The number of through holes 220 matches the number of conductive pins 121. The conductive pins 121 pass through the through holes 220 and their ends extend to the bottom of the groove 210 flush with it. Alternatively, in order to improve the sealing effect at the connection, in this embodiment, the conductive pins 121 pass through the through holes 220.

[0055] from Figure 4 and Figure 5 As can be seen, two of the conductive pins 121 pass through the sealing layer 300 and connect to the temperature sensor 500. The ends of the remaining six conductive pins 121 extend to the bottom of the groove 210 flush with it, or extend beyond the bottom but not beyond the top surface of the groove 210; preferably, they extend beyond the bottom by 0.2 to 0.5 mm, so that the glue can cover the connection. The remaining six conductive pins 121 are connected to the rotary transformer 400 through the wire harness 600.

[0056] like Figure 7 As shown, the groove 210 is square or rectangular in shape, which provides a wider injection port for dispensing, thus improving dispensing efficiency.

[0057] Among them, Figure 6In the process, a thick sealing layer 300 is formed by glue in the through hole 220 and the groove 210, and the outer end face of the sealing layer 300 is flush with the end face of the sealing part 130, so that the glue can seal the connection between the wire harness 600 and the conductive pin 121 (generally by welding), and prevent the connection between the wire harness 600 and the conductive pin 121 from being exposed to the outside, which can effectively prevent airtightness problems.

[0058] Specifically, in Figure 6 In this process, the through hole 220 and the conductive pin 121 are fitted with a gap, which facilitates the filling of the gap between them with glue. The cured glue forms a sealing layer, and the adhesion between the glue-filled area and the through hole 220 is good, forming a physical isolation zone that completely cuts off the oil and gas permeation path and achieves sealing throughout the entire axial direction. This improves the sealing effect, simplifies the process steps, and reduces production and manufacturing costs. In addition, it can play a good role in shock absorption.

[0059] The aforementioned adhesive (epoxy resin) can be either ENIENT EG0510B or ENIENT EG0510C, which possesses strong adhesion, temperature resistance, and moisture resistance, thus preventing leakage.

[0060] Multiple sealing structures are formed along the direction of the conductive pin 121. Even if grease or oil vapor in the cylinder seeps through one sealing structure, multiple subsequent sealing structures will block the seeping grease or oil vapor, thereby enhancing the sealing performance between the conductive pin 121 and the main body shell 100 and the sealing end plate 200, and solving the technical problem of poor airtightness of the cylinder connector in the prior art.

[0061] In this embodiment, the main body shell 100 is made of a high-temperature resistant and impact-resistant insulating material, such as PBT, PA66, PPS, etc., to adapt to the high temperature and vibration environment of the cylinder. A mounting ear 110 is provided on the outer side of the main body shell 100. The mounting hole of the mounting ear 110 is round, oblong, or other shapes to accommodate mounting screws, which facilitates use in different assembly scenarios. Considering the material of the main body shell 100, a metal fitting, such as a steel metal ring, is provided in the mounting hole to prevent the fastening screw from damaging the main body shell 100. The cylinder connector is connected to the cylinder by screws.

[0062] Furthermore, in order to ensure the stability of the vehicle during driving, in this embodiment, two mounting ears 110 are provided on the outer side of the main body shell 100. The two mounting ears 110 are symmetrically arranged, and the mounting holes of the two mounting ears 110 are round, oblong, or other shapes adapted to mounting screws.

[0063] Among them, such as Figure 5 , Figure 6 and Figure 7As shown, one end of the main body shell 100 is provided with a plug-in portion 120, which has a plurality of conductive pins 121 inside; the other end of the main body shell 100 is provided with a sealing portion 130, which faces the inside of the motor cylinder and forms a sealing cavity 131, and the conductive pins 121 extend into the sealing cavity 131; the sealing portion 130 is provided with four light-reducing holes 132, which are located at the upper middle part of the four corners of the sealing portion 130 respectively.

[0064] Furthermore, such as Figure 5 As shown, a sealing element 140 is fitted in the middle of the main body shell 100. The sealing element 140 is located on the insertion part 120 and is used to seal both sides of the cylinder body after cylinder installation to prevent liquid and gas leakage.

[0065] Furthermore, the sealing element 140 is a sealing ring made of rubber or silicone, with a circular, rectangular or irregular cross-section, adapted to the sealing requirements after the main body shell 100 and the cylinder are installed. The sealing ring is interference-fitted with the main body shell 100 or installed by limiting the position through a slot or other structure to ensure that the sealing element 140 is stable and the sealing is reliable after installation.

[0066] In this embodiment, as Figure 7 As shown, the conductive pins 121 are made of copper or copper alloy, and their surfaces are treated with anti-oxidation agents such as tin plating or silver plating to improve conductivity and corrosion resistance. Preferably, there are 12 conductive pins 121, which are arranged in a matrix or linear pattern within the connector 120 to ensure precise mating with the adapter plug. Two of the conductive pins 121 pass through the sealing layer 300 and connect to the temperature sensor 500 (NTC). The ends of the remaining six conductive pins 121 extend to the bottom of the groove 210, flush with it, or extend beyond the bottom but not beyond the top surface of the groove 210; preferably, they extend beyond the bottom by 0.2 to 0.5 mm. The remaining six conductive pins 121 are connected to the rotary transformer 400 via a wire harness 600.

[0067] Example 2

[0068] like Figure 2 and Figure 3 As shown, the integrated through-cylinder wiring harness assembly mounting structure of this embodiment includes a cylinder body and the integrated through-cylinder wiring harness assembly described in Embodiment 1. A mounting hole is provided on the cylinder body 700, and the through-cylinder connector is detachably mounted (e.g., by screw connection) at the mounting hole of the cylinder body 700. The rotary transformer 400 and the temperature sensor 500 (NTC) are disposed inside the cylinder body 700.

[0069] Example 3

[0070] In this embodiment of the vehicle, the integrated through-cylinder wiring harness assembly mounting structure is installed on the vehicle's cylinder block 700. In the integrated oil-cooled powertrain of new energy vehicles, the integrated through-cylinder wiring harness assembly of this invention can realize the connection between internal electrical components and external control units.

[0071] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
