Description

Technical Field

[0001] This invention relates to the field of wire harness rubber sleeve technology, and in particular to a high flame-retardant new energy vehicle wire harness rubber sleeve and its preparation method. Background Technology

[0002] Currently, the typical structure of rubber sleeves for automotive wiring harnesses passing through single sheet metal holes is as follows: a round hole is made in the center of the rubber sleeve to allow the wiring harness to pass through, and a sleeve or spoiler is designed on one or both sides of the hole to facilitate binding the wiring harness and the rubber sleeve with tape, preventing relative movement between them. However, in actual use, especially when the vehicle is at a non-uniform speed, a certain impact force is generated between the rubber sleeve and the sheet metal hole, increasing the fatigue strength of the rubber sleeve and reducing its lifespan. Furthermore, long-term or frequent operation under these conditions reduces the sealing performance of the rubber sleeve, thereby affecting the overall performance of the vehicle.

[0003] In the existing technology, most wire harness rubber sleeves cannot be stretched or compressed, which means that different models of wire harness rubber sleeves need to be replaced when used for wire harnesses of different lengths, causing great inconvenience to operators. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a high flame-retardant rubber sleeve for new energy vehicle wiring harnesses and its preparation method, so as to solve the above problems.

[0005] In view of this, the present invention provides a high flame-retardant rubber sleeve for new energy vehicle wiring harnesses, comprising: A rubber corrugated pipe includes a rubber corrugated section and two connecting rubber tubes disposed at both ends of the rubber corrugated section; Two connectors, one end of which is inserted into the inner wall of the two connecting rubber tubes, and the other end of each extends out of the connecting rubber tube; And two locking pieces, which are respectively fitted onto the outer walls of the two connecting rubber tubes; The connector is used to connect and fix the rubber corrugated pipe, and the locking member is used to securely connect the connector to the connecting rubber pipe.

[0006] By adopting the above technical solution, the corrugated rubber section can achieve the functions of extension and compression, so that wires of different lengths can be wrapped and thus play a protective role. The connecting rubber tube can connect the two connectors, and the two connectors can fix the entire corrugated rubber tube in place. The two locking parts can securely connect the connecting rubber tube and the connector.

[0007] In the above technical solution, the connecting component further includes: The hollow tube has one end inserted into the inner wall of the connecting rubber tube, and the other end extends out of the connecting rubber tube. Two connecting blocks are respectively connected to both ends of the outer wall of the hollow tube; Several dividing rods are arranged in a circumferential array on the inner wall of the hollow tube at one end, and the other end of each rod extends toward the central axis of the hollow tube. Several rotating rods, one end of which is rotatably connected to the end of the separator rod away from the inner wall of the hollow tube, and the other end extends toward the inner wall of the hollow tube; Several elastic elements are connected at one end to the dividing rod and at the other end to the rotating rod; The connecting block is provided with a threaded hole for connection, and the elastic element is used to pull the rotating rod to abut against the inner wall of the hollow tube.

[0008] In this technical solution, the hollow tube can be connected to the connecting rubber tube, the connecting block allows the hollow tube to be installed, and the cooperation of the separator rod and the rotating rod separates the wires. The elastic element ensures that the rotating rod is always in contact with the inner wall of the hollow tube, preventing the wire from falling out when it is between the rotating rod and the separator rod. Since the rotating rod rotates around the separator rod, it can no longer contact the inner wall of the hollow tube when it rotates to a larger angle, allowing the wire to move between the rotating rod and the separator rod.

[0009] In the above technical solution, the locking element further includes: A notched ring is fitted onto the outer wall of the connecting rubber tube; Two locking rods are connected to the notches of the notch ring respectively; The two locking rods are locked together by bolts.

[0010] In this technical solution, the cooperation of two locking rods and bolts enables the notched ring to press tightly against the connecting rubber tube, thereby preventing the connecting rubber tube from separating from the hollow tube.

[0011] The above technical solution further includes the following steps: S1: First, use a conventional mold to process a hollow tube, several partition rods and connecting blocks, then rotate the rod to connect it to the partition rod and install the elastic element; S2: Then, rubber corrugated pipes are produced using a glue injection molding device; S3: Finally, insert the two hollow tubes into the connecting rubber tubes at both ends of the connecting rubber tube, then place the notched ring on the outer wall of the connecting rubber tube, and finally tighten the bolts to lock the locking rod.

[0012] In this technical solution, by setting S1, connectors can be produced; by setting S2, rubber corrugated pipes can be produced; and by setting S3, the entire assembly can be installed.

[0013] In the above technical solution, the injection molding device further includes: The molding mechanism is located on the ground. The support frame has its fixed end set on the ground and its supporting end located above the forming mold; The degumming liquid application mechanism has its fixed end set on the ground and its output end extending toward the molding die mechanism; And the glue injection mechanism, with the fixed end mounted on the support frame and the output end extending toward the molding die mechanism; The degumming liquid application mechanism is used to apply degumming liquid to the inner wall of the molding mold mechanism, and the glue injection mechanism is used to deliver glue into the molding mold mechanism.

[0014] In this technical solution, the support frame enables the installation of the degumming liquid application mechanism and the glue injection mechanism. The degumming liquid application mechanism applies degumming liquid to the molding mold mechanism, thereby facilitating the removal of the molded rubber corrugated tube. The glue injection mechanism injects glue into the molding mold mechanism, thereby forming the rubber corrugated tube within the molding mold mechanism.

[0015] In the above technical solution, the further described degumming liquid application mechanism includes: Two first support plates are spaced apart at the top of the support frame; The skateboard is slidably connected between the two first support plates; The first hydraulic cylinder has its fixed end located at the top of the support frame and its output end connected to two first support plates; The rotating motor has its fixed end located at the top of the slide plate, and its output end passes through the first support plate and the support frame. The degumming liquid application structure has a fixed end connected to the output end of a rotating motor, with the output end extending toward the molding die mechanism; The first hydraulic cylinder is used to lower the slide plate, thereby causing the rotating motor to push the degumming liquid application structure to descend.

[0016] In this technical solution, the two first support plates enable the slide plate to slide up and down in a limited manner. The first hydraulic cylinder enables the slide plate to slide up and down automatically. The rotating motor enables the degumming liquid coating structure to rotate and descend, thereby uniformly coating the inner wall of the molding mold mechanism from bottom to top with degumming liquid. The degumming liquid coating structure enables the degumming liquid to be applied inside the molding mold mechanism.

[0017] In the above technical solution, the further degumming liquid coating structure includes: Two second support plates are spaced apart on both sides of the bottom end of the support frame and located on both sides of the output end of the rotating motor; A rotating disk is fixedly connected to the output end of a rotating motor and located between two second support plates. The rotating disk is provided with a plurality of vortex-shaped holes arranged in a circumferential array around the central axis of the rotating disk. A limiting plate is attached to the bottom of the rotating plate, and the limiting plate is provided with a number of strip holes arranged circumferentially around the central axis of the limiting plate. The driving component is connected at one end to the outer wall of the rotating disk and at the other end to the outer wall of the limiting disk. Two limiting blocks, one end of which is connected to the outer wall of the limiting plate, and the other end slides on the inner wall of the second support plate; Several output tubes, one end of which is located at the top of the rotating disk, and the other end passes through a vortex hole and a strip hole. A limiting ring that slides within the inner wall of the strip hole is provided on the outer wall of the output tube. The liquid storage structure has a fixed end located at the top of the rotating disk, and the output end is connected to the top openings of several output tubes respectively. The liquid storage structure is used to store the degumming liquid and deliver it to the output pipe. The end of the output pipe away from the liquid storage structure is provided with an applicator sponge. The two second support plates are arranged opposite each other and are provided with sliding grooves for the limiting blocks to slide. The outer wall of the limiting plate is provided with an annular groove for the drive component to rotate. The inner wall of the strip hole is provided with a limiting groove for the limiting ring to slide.

[0018] In this technical solution, the cooperation of two second support plates, a sliding groove, and a limiting block allows the limiting disk to descend but not rotate. By cooperating with the vortex hole of the rotating disk and the strip hole of the limiting disk, the output pipe can only move back and forth in the direction of the strip hole, thereby increasing or decreasing the diameter of the circle formed between several output pipes. This achieves complete coating of the inner wall of the corrugated tubular hole. The liquid storage structure allows the degumming liquid to be placed in and transported to the output pipe, which then transfers the degumming liquid to the coating sponge. Finally, the coating sponge applies the degumming liquid to the inner wall of the corrugated tubular hole.

[0019] In the above technical solution, the molding die mechanism further includes: The slide rail is set on the ground and moves from below the adhesive stripping agent application mechanism to the adhesive injection mechanism; The drive motor is mounted on a fixed slide rail, with its output end extending toward the output end of the adhesive stripping mechanism. The support block is connected to the output end of the drive motor; Two support rods are spaced apart on both sides of the top of the support block; The injection module is installed at the top of two support rods, and the injection module is provided with corrugated tubular holes; And the molding component, with the fixed end set at the top of the support block and the output end able to extend into and out of the corrugated tubular hole; When the molding component extends into the corrugated tubular hole, the output end of the glue injection mechanism engages with the top opening of the corrugated tubular hole to input glue for molding.

[0020] In this technical solution, the corrugated tubular hole can be rotated by the drive motor, so that the degumming and coating mechanism can apply the degumming liquid evenly. The slide rail can move the degumming liquid to the injection mechanism after it is applied to the corrugated tubular hole for injection molding. The carrier block can be used to install two support rods. The carrier block can be used to process the corrugated tubular hole. The corrugated tubular hole can be used to form the corrugated tubular cavity required for processing when the molding component is inserted.

[0021] In the above technical solution, the further molding component includes: The second hydraulic cylinder is located at the top of the bearing block and between the two support rods; The sealing plate is located on the output end of the second hydraulic cylinder; And a corrugated tubular block, one end of which is connected to the top of the sealing plate and the other end extends toward the corrugated tubular hole; When the second hydraulic cylinder pushes the sealing plate to fit against the bottom of the support block, the corrugated tubular block extends into the corrugated tubular hole, and at this time, a forming cavity is formed between the corrugated tubular block and the corrugated tubular hole.

[0022] In this technical solution, the second hydraulic cylinder enables the sealing plate to rise and thus contact the bottom opening of the corrugated tubular hole to form a seal. The corrugated tubular block forms a forming cavity with the corrugated tubular hole. Attached Figure Description

The corrugated rubber section enables extension and compression, allowing wires of different lengths to be wrapped and thus providing protection. The connecting rubber tube 2 connects the two connectors, which in turn securely fix the entire corrugated rubber tube 1.

The separation rod 5 and the rotating rod 6 work together to separate the wires. The elastic element 7 ensures that the rotating rod 6 is always in contact with the inner wall of the hollow tube 3, so that the wire cannot fall out when it is between the rotating rod 6 and the separation rod 5.
