Description

Technical Field

[0001] The present invention relates to the technical field of wire harness fixing, and specifically relates to an automotive wire harness fixing pipe clamp. Background Art

[0002] The function of an automotive wire harness fixing pipe clamp is to fix the wire harness inside the vehicle, ensure that the wire harness maintains the correct position, and prevent damage and potential electrical faults caused by vibration, friction or movement. With the development of electrification and intelligence, the number and complexity of in-vehicle electronic devices have been continuously increasing, which has led to a significant increase in the number of wire harnesses inside the vehicle, and the requirements for the management and fixing of wire harnesses have also increased accordingly.

[0003] Currently, most wire harness pipe clamps are independently designed. Usually, each pipe clamp can only fix one wire harness. When fixing a large number of wire harnesses, a large number of pipe clamps are required. One by one, the pipe clamps are connected to the wire harnesses, and then the pipe clamps are installed at the corresponding positions or components on the vehicle body. The whole process is very cumbersome, which not only increases the installation time and cost, but also easily leads to chaotic wiring and reduces the convenience of maintenance and inspection. Summary of the Invention

[0004] The present invention provides an automotive wire harness fixing pipe clamp to solve the problems in the related technologies that the fixing process of a large number of wire harnesses is cumbersome, the installation time and cost are high, it is easy to cause chaotic wiring, and the convenience of subsequent maintenance and inspection is low.

[0005] The present invention provides an automotive wire harness fixing pipe clamp. The automotive wire harness fixing pipe clamp includes a connecting belt, and a plurality of fixing heads for fixing wire harnesses are arranged on the connecting belt. In the unfolded state of the connecting belt, the plurality of fixing heads are linearly distributed. In the state where the head and tail of the connecting belt are fixedly connected, the plurality of fixing heads are concentrated together and located in the connecting belt; the fixing head includes a clamping and fixing part provided with a limiting end, the clamping and fixing parts are symmetrically distributed, and a plurality of limiting tightening heads, and the plurality of limiting tightening heads are respectively located between adjacent fixing heads. In the unfolded state of the connecting belt, the wire harness is in a preliminary limiting and fixing state in the symmetric clamping and fixing parts. In this state, the wire harness can move axially. During the process of the connecting belt changing from the unfolded state to the state of head and tail connection, the symmetric clamping and fixing parts are gradually tightened and clamped to fix the middle wire harness under the limitation of the limiting tightening heads, and in the early stage of tightening and clamping, the wire harness can be adjusted in position state adaptively or manually to sort out the wire harness during the process of centrally fixing the wire harness; a unified reinforcement head; the unified reinforcement head includes a base body provided with a locking component and a plurality of limiting members. After the head and tail of the connecting belt are fixedly connected, the locking component fixedly connects the base body with the limiting tightening heads adjacent to the head and tail of the connecting belt, so that the head and tail ends of the connecting belt are stably connected together, and the limiting members on the base body limit the limiting ends on the clamping and fixing parts to uniformly control the symmetric clamping and fixing parts to clamp the wire harness.

[0006] In a possible implementation manner, the connection belt is fixedly connected at the head and tail to form a frame-shaped concentration area, and the connection belt includes a plurality of mounting plates and a plurality of connecting plates. The mounting plates and the connecting plates are alternately distributed in sequence. One end of one connecting plate is detachably connected to the adjacent mounting plate, and the other end of this connecting plate and both ends of the remaining connecting plates are hinged to the adjacent mounting plates. The mounting plates correspond to the fixing heads one by one, and the fixing heads are mounted on the corresponding mounting plates. The connecting plates correspond to the limiting tightening heads one by one, and the limiting tightening heads are mounted on the corresponding connecting plates.

[0007] In a possible implementation manner, the limiting tightening head is fixedly connected to the connection belt. The base body includes a sliding member, a connecting member, and a central member. A plurality of limiting members are all mounted on the central member. The sliding member and the connecting member are both fixedly mounted on the central member. The two limiting tightening heads adjacent to the head and tail ends of the connection belt respectively correspond to the sliding member and the connecting member. The sliding member is slidably connected to the corresponding limiting tightening head. The locking assembly is used to fixedly connect the sliding member and the corresponding limiting tightening head and the connecting member and the corresponding limiting tightening head together. A secondary reinforcement area is formed between the head and tail ends of the connection belt to stably connect the head and tail ends of the connection belt together. Among them, a force applying member is fixedly connected to the central member, and the force applying member and the sliding member are distributed along the same straight line.

[0008] In a possible implementation manner, the locking assembly includes a clamping seat, a clamping claw, a rotating member, a locking member, and an elastic member. The rotating member is rotatably connected to the clamping claw. The clamping claw is slidably mounted on the corresponding limiting tightening head. During the movement of the base body, the elastic member makes the clamping claw in an elastically connected state, and the clamping seat will automatically buckle with the clamping claw. After the clamping seat and the clamping claw are automatically buckled together, locking restrictions are implemented through the rotating member and the locking member to stably buckle the clamping claw and the clamping seat together.

[0009] In a possible implementation manner, the clamping and fixing part is of an arc-shaped structure, and one end of the clamping and fixing part close to the connection belt is hinged to the connection belt. A clamping member is connected between the symmetrically arranged ends of the clamping and fixing part far from the connection belt. The clamping member includes a frame-shaped clamping rod and a limiting frame provided with a clamping opening. The clamping rod is inserted into the limiting frame through the clamping opening. After the clamping rod is inserted into the limiting frame, during the process of the symmetrically arranged clamping and fixing parts clamping and fixing the wire harness, the clamping rod can move relative to the limiting frame.

[0010] In a possible implementation manner, a limiting groove is arranged on the outer side of the clamping and fixing part. The limiting tightening head cooperates with the limiting groove to limit the clamping and fixing part in two directions, namely the radial direction and the axial direction, of the wire harness.

[0011] One or more of the above technical solutions in the embodiments of the present invention have at least one of the following technical effects: 1. When the connecting belt provided with a plurality of fixing heads is in an unfolded state, a plurality of wire harnesses are correspondingly installed on the fixing heads, and then the connecting belt is fixedly connected at the head and the tail to gather a plurality of wire harnesses together. During the process of gathering the wire harnesses, the position state of the wire harnesses can be adjusted to improve the neatness of the centralized arrangement of the wire harnesses. After the wire harnesses are gathered, the wire harnesses are further fixed to improve the stability of the wire harness fixing. And as a whole, only one fixing connection point is required to install a plurality of wire harnesses in the vehicle body, effectively simplifying the process of wire harness fixing, and improving the efficiency, stability and neatness of wire harness fixing.

[0012] 2. When the connecting belt in the present invention is in an unfolded state, the symmetric clamping and fixing parts first quickly limit and fix the wire harnesses. During the process of fixedly connecting the head and the tail of the connecting belt, the limit tightening head automatically limits the symmetric clamping and fixing parts, so that the symmetric clamping and fixing parts further clamp and fix the wire harnesses. After the head and the tail of the connecting belt are fixedly connected, the unified reinforcement head finally uniformly limits the symmetric clamping and fixing parts, so that the symmetric clamping and fixing parts further clamp and fix the wire harnesses, improving the firmness of wire harness fixing, and the whole wire harness fixing process can be completed quickly and conveniently.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific embodiments of the present invention will be provided in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 , an automotive wire harness fixing pipe clamp, comprising a connecting band 1, a plurality of fixing heads 2, a plurality of limiting tightening heads 4, and a unified reinforcement head 5. The fixing heads 2 are used to fix the wire harness 3. A plurality of fixing heads 2 fix a plurality of wire harnesses 3. When the connecting band 1 is in an unfolded state, the plurality of fixing heads 2 are linearly and evenly arranged. The plurality of limiting tightening heads 4 are respectively located between adjacent fixing heads 2 and fixedly installed on the connecting band 1. At this time (i.e., when the connecting band 1 is in an unfolded state), the wire harness 3 can be sequentially placed in the fixing heads 2 for preliminary limiting and fixing. After the wire harness 3 is placed in each of the plurality of fixing heads 2, the head and tail of the connecting band 1 are fixedly connected together, so that the plurality of fixing heads 2 are concentrated and located in the connecting band 1. During this process, as the fixing heads 2 gather, the limiting tightening heads 4 automatically limit the adjacent fixing heads 2, causing the fixing heads 2 to gradually tighten and clamp the corresponding wire harness 3. And before the wire harness 3 is completely tightened and fixed, the wire harness 3 can be adjusted in its position state adaptively or manually, sorting the wire harness 3 during the process of centrally fixing the plurality of wire harnesses 3, improving the neatness of the plurality of wire harnesses 3, facilitating later inspection and maintenance. And after the head and tail of the connecting band 1 are fixedly connected, the unified reinforcement head 5 uniformly controls the fixing heads 2 to further tighten and clamp the corresponding wire harness 3, and at the same time increases the firmness of the connection between the head and tail of the connecting band 1, improving the stability and reliability of the overall structure during use.

[0021] Refer to Figure 1 , Figure 3 and Figure 4, the fixed head 2 includes a clamping and fixing part 22 provided with a limit end 21. The clamping and fixing parts 22 are symmetrically distributed. The clamping and fixing parts 22 are of an arc-shaped structure. The ends of the symmetric clamping and fixing parts 22 close to the connecting belt 1 are both hinged to the connecting belt 1, and the other ends are buckled together. During the installation process, only need to place the wire harness 3 between the symmetric clamping and fixing parts 22, and then buckle the symmetric clamping and fixing parts 22 together to quickly complete the preliminary limit fixing of the wire harness 3; then quickly fixedly connect the head and the tail of the connecting belt 1 together. The head and the tail of the connecting belt 1 can also be automatically buckled together through a buckle; the limit tightening head 4 is of an isosceles triangle structure. The number of the fixed heads 2 and the limit tightening heads 4 is four each, and the fixed heads 2 and the limit tightening heads 4 are alternately distributed in sequence. The head and the tail of the connecting belt 1 are fixedly connected to form a frame-shaped concentrated area. The fixed heads 2 and the limit tightening heads 4 are both located in the concentrated area; during the process of fixedly connecting the head and the tail of the connecting belt 1, the limit tightening head 4 will automatically squeeze the clamping and fixing part 22, so that the symmetric clamping and fixing parts 22 rotate relatively to clamp and fix the wire harness 3 in the middle. And before the wire harness 3 is completely clamped and fixed, as the position of the fixed head 2 changes, the wire harness 3 can be adjusted adaptively or manually to make multiple wire harnesses 3 neatly gathered and fixed together.

[0022] Refer to Figure 1 , Figure 3 and Figure 4 , a clamping part 23 is connected between the ends of the symmetric clamping and fixing parts 22 away from the connecting belt 1. The clamping part 23 includes a frame-shaped clamping rod 231 and a limit frame 233 provided with a clamping opening 232. The clamping rod 231 is inserted into the limit frame 233 through the clamping opening 232. After the wire harness 3 is placed between the symmetric clamping and fixing parts 22, by pressing the symmetric clamping and fixing parts 22, the clamping rod 231 is inserted into the limit frame 233 through the clamping opening 232. At this time, the wire harness 3 is in a state of preliminary limit fixing. Then, during the process of the symmetric clamping and fixing parts 22 continuing to rotate relatively to clamp and fix the wire harness 3, the clamping rod 231 can move relatively to the limit frame 233; as shown in Figure 4 , the limit frame 233 is an elastic U-shaped frame, the clamping opening 232 is a cylinder, and cylinders are provided at both ends of the two parallel segments of the elastic U-shaped frame.

[0023] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, the unified reinforcement head 5 includes a base body 53 provided with a locking component 51 and a number of limiting components 52. The locking component 51 fixedly connects the base body 53 with two limiting tightening heads 4 adjacent to the head and tail ends of the connecting belt 1, so that the head and tail ends of the connecting belt 1 are firmly connected together. The limiting components 52 limit the limiting ends 21 on the clamping and fixing parts 22 to uniformly control the symmetrical clamping and fixing parts 22 to clamp the wire harness 3; the base body 53 includes a sliding part 531, a connecting part 532 and a central part 533. The central parts 533 are symmetrically distributed front and back. A number of limiting components 52 are evenly divided into two groups and are respectively installed on the symmetrical central parts 533, and the limiting components 52 on the central parts 533 correspond one by one to the limiting ends 21. The sliding part 531 and the connecting part 532 are both fixedly installed on the central part 533, and the sliding part 531 is slidably connected to the limiting tightening head 4 adjacent to the head end of the connecting belt 1. The connecting part 532 corresponds to the limiting tightening head 4 adjacent to the tail end of the connecting belt 1. During the process of unified reinforcement connection of the unified reinforcement head 5, the central part 533 is pressed to make the symmetrical central parts 533 move relatively. The limiting components 52 thereon limit the corresponding limiting ends 21, so that the symmetrical clamping and fixing parts 22 rotate relatively, further clamping and fixing the wire harness 3 in the middle. The sliding part 531 slides accordingly, and the connecting part 532 is synchronously inserted into the corresponding limiting tightening head 4 until the locking component 51 automatically fixedly connects the sliding part 531 with the corresponding limiting tightening head 4 and the connecting part 532 with the corresponding limiting tightening head 4. The entire installation process of the wire harness 3 is convenient and fast, and the position of the wire harness 3 can be flexibly adjusted during the fixing process, improving the convenience of centralized fixing of multiple wire harnesses 3 and the neatness after fixing, and correspondingly improving the convenience of later maintenance and detection. Among them, the limiting end 21 is a limiting block with inclined surfaces symmetrically arranged at the front and rear ends, and the limiting component 52 is a connecting block provided with a limiting roller. During the process of the limiting component 52 moving with the central part 533, the limiting roller cooperates with the inclined surface to limit the clamping and fixing part 22, so that the symmetrical clamping and fixing parts 22 rotate relatively.

[0024] Refer to Figure 1 , Figure 3 and Figure 4, the connecting belt 1 includes a plurality of mounting plates 101 and a plurality of connecting plates 102. The mounting plates 101 and the connecting plates 102 are alternately distributed in sequence. One end of one connecting plate 102 is detachably connected to the adjacent mounting plate 101, and the other end of this connecting plate 102 and both ends of the remaining connecting plates 102 are hinged to the adjacent mounting plates 101. The mounting plates 101 correspond to the fixing heads 2 one by one, and the fixing heads 2 are installed on the corresponding mounting plates 101. The connecting plates 102 correspond to the limiting tightening heads 4 one by one, and the limiting tightening heads 4 are installed on the corresponding connecting plates 102. The number of both the mounting plates 101 and the connecting plates 102 is four. After the alternately distributed mounting plates 101 and connecting plates 102 are fixedly connected together at the head and tail ends, a rigid frame-shaped concentrated area is formed, which is beneficial to further improving the stability and reliability of the overall structure.

[0025] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 5, the locking component 51 includes a clamping seat 511, a claw 512, a rotating member 513, a locking member 514 and an elastic member 515. There are several clamping seats 511, and the numbers of the claw 512, the rotating member 513, the locking member 514 and the elastic member 515 are all two. The rotating members 513 correspond to the claws 512 one by one. One end of the rotating member 513 is rotatably installed on the corresponding claw 512, and the other end passes through the corresponding connecting plate 102 and is located outside the concentration area. The two claws 512 are respectively slidably installed on two limiting tightening heads 4 adjacent to the head and tail ends of the connecting belt 1. The elastic member 515 is connected between the claw 512 and the corresponding limiting tightening head 4. The locking member 514 is fixedly installed on the corresponding connecting plate 102. The clamping seats 511 are respectively fixedly connected to the sliding member 531 and the connecting member 532. During the process of pressing the central member 533, the clamping seats 511 will pass by the claws 512 along with the movement of the sliding member 531 and the connecting member 532 and automatically buckle with the corresponding claws 512. During this process, the elastic member 515 is used to initially buckle the clamping seat 511 and the corresponding claw 512 together. At this time, the central member 533 can only continue to move along the pressing direction and cannot move in the reverse direction; the locking member 514 is a convex block with a groove, and the rotating member 513 is a column with a protrusion. After the clamping seat 511 and the corresponding claw 512 are initially buckled together, first move the rotating member 513 outward to further buckle the claw 512 and the clamping seat 511 together to ensure the stability of the buckling state between the two. Then rotate the rotating member 513 to align the protrusion with the groove, and then stop rotating the rotating member 513. At this time, under the action of the resilience of the elastic member 515, the rotating member 513 will move inward to embed the protrusion in the groove, but the backward movement distance of this section of the rotating member 513 is less than the outward movement distance of the rotating member 513, so as to improve the stability of the position state of the rotating member 513 and correspondingly improve the stability of the locking state of the locking component 51. During the disassembly process, only need to move the rotating member 513 outward and rotate the rotating member 513 back, and then press the rotating member 513 inward to separate the claw 512 from the clamping seat 511; wherein, a force applying member 534 is fixedly connected to the central member 533. The force applying member 534 and the sliding member 531 are distributed on both sides of the central member 533 along the same straight line. The head and tail of the connecting belt 1 are fixedly connected with hooks. The force applying member 534 extends from the center of the bundled wire harness 3 to the outside. During the process of pressing the central member 533, at this time, only need to synchronously press the force applying member 534 and the sliding member 531 from the outside of the bundled wire harness 3 to realize the pressing of the central member 533, which is convenient for use.

[0026] Refer to Figure 3 and Figure 4, a limiting groove 54 is provided on the outer side of the clamping and fixing part 22. The limiting tightening head 4 cooperates with the limiting groove 54 to limit the clamping and fixing part 22 from two directions of the radial and axial directions of the wire harness 3. During the process of fixedly connecting the head and the tail of the connecting belt 1, the limiting tightening head 4 is embedded in the limiting groove 54 on the adjacent clamping and fixing part 22. On the one hand, it makes the symmetrical clamping and fixing parts 22 rotate relatively to clamp and fix the middle wire harness 3, and on the other hand, it limits the clamping and fixing part 22 axially, so that the symmetrical clamping and fixing parts 22 can stably carry out the clamping and fixing work, improving the stability of the wire harness 3 during the fixing process.
