Description

Technical Field

[0001] The invention relates to the technical field of wire harness fixing, in particular to a pipe clamp for fixing an automobile wire harness. Background Art

[0002] The function of automobile wiring harness fixing pipe clamps is to fix the wiring harness inside the vehicle, ensure that the wiring harness remains in the correct position, and prevent damage and potential electrical failures due to vibration, friction or movement. With the development of electrification and intelligence, the number and complexity of automotive electronic equipment continue to increase, which has led to a significant increase in the number of wiring harnesses in the vehicle, and the requirements for the management and fixation of the wiring harness have also increased accordingly.

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

[0004] The present invention provides an automobile wiring harness fixing pipe clamp to solve the problems in the related art of a large number of wiring harness fixing processes being cumbersome, high installation time and cost, easily leading to wiring confusion, and low convenience in subsequent maintenance and inspection.

[0005] The present invention provides an automobile wiring harness fixing pipe clamp, which includes a connecting belt, and a plurality of fixing heads for fixing the wiring harness are provided on the connecting belt. When the connecting belt is in an expanded state, the plurality of fixing heads are linearly distributed. When the connecting belt is in a state where the ends are fixedly connected, the plurality of fixing heads are concentrated together and located in the connecting belt. The fixing head includes a clamping fixing portion with a limited end, the clamping fixing portion is symmetrically distributed, and a plurality of limiting tightening heads are respectively located between adjacent fixing heads. When the connecting belt is in an expanded state, the wiring harness is located in the symmetrical clamping fixing portions and is initially limited and fixed. In this state, the wiring harness can move in the axial direction, and the connecting belt changes from an expanded state to a limited state. During the tail connection state, the symmetrical clamping and fixing parts gradually tighten and clamp the middle wire harness under the limit of the limit tightening head, and in the early stage of tightening and clamping, the wire harness can adaptively or manually adjust the position state to organize the wire harness in the process of centralized fixation of the wire harness; unified reinforcement head; the unified reinforcement head includes a base body provided with a locking assembly and a plurality of limiters. After the head and tail of the connecting belt are fixedly connected, the locking assembly fixes the base body and the limit tightening heads adjacent to the head and tail of the connecting belt together, so that the head and tail ends of the connecting belt are firmly connected together, and the limit end on the clamping and fixing part is limited by the limiter on the base body, and the symmetrical clamping and fixing parts are uniformly controlled to clamp the wire harness.

[0006] In one possible implementation, the connecting belt is fixedly connected at both ends to form a frame-shaped concentrated area, and the connecting belt includes a plurality of mounting plates and a plurality of connecting plates, and 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 the connecting plate and both ends of the remaining connecting plates are hinged to the adjacent mounting plates, the mounting plates correspond one-to-one to the fixing heads, the fixing heads are installed on the corresponding mounting plates, the connecting plates correspond one-to-one to the limiting tightening heads, and the limiting tightening heads are installed on the corresponding connecting plates.

[0007] In one possible implementation, the limit tightening head is fixedly connected to the connecting belt, the base includes a sliding part, a connecting part and a center part, several limit parts are installed on the center part, the sliding part and the connecting part are fixedly installed on the center part, the two limit tightening heads adjacent to the head and tail ends of the connecting belt correspond to the sliding part and the connecting part respectively, the sliding part is slidably connected to the corresponding limit tightening head, and the locking assembly is used to fix the sliding part and the corresponding limit tightening head together, and a secondary reinforcement area is formed between the head and tail ends of the connecting belt, so that the head and tail ends of the connecting belt are firmly connected together, wherein a force-applying part is fixedly connected to the center part, and the force-applying part and the sliding part are distributed along the same straight line.

[0008] In one possible implementation, the locking assembly includes a base, a claw, a rotating member, a locking member and an elastic member. The rotating member is rotatably connected to the claw, and the claw is slidably installed on the corresponding limit tightening head. During the movement of the base, the elastic member puts the claw in an elastically connected state, and the base will automatically be buckled with the claw. After the base and the claw are automatically buckled together, the locking restriction is implemented by the rotating member and the locking member, so that the claw and the base are firmly buckled together.

[0009] In one possible implementation, the clamping and fixing portion is an arc-shaped structure, and the clamping and fixing portion is hinged to the connecting belt at one end close to the connecting belt, and a clamping part is connected between the ends of the symmetrical clamping and fixing portions away from the connecting belt. The clamping part includes a frame-shaped clamping rod and a limit frame provided with a bayonet. The clamping rod is clamped into the limit frame by the bayonet. After the clamping rod is clamped into the limit frame, the clamping rod can move relative to the limit frame during the process of the symmetrical clamping and fixing portions clamping and fixing the wiring harness.

[0010] In a possible implementation, a limiting groove is provided on the outer side of the clamping and fixing portion, and the limiting tightening head cooperates with the limiting groove to limit the clamping and fixing portion in both radial and axial directions of the wiring harness.

[0011] The above one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: 1. When the connecting belts of several fixed heads are provided in the unfolded state, the present invention installs several wire harnesses on the fixed heads accordingly, and then fixes the connecting belts at the head and tail to make the several wire harnesses gathered together. During the process of wire harness gathering, the position state of the wire harnesses can be adjusted to improve the neatness of the concentrated arrangement of the wire harnesses, and after the wire harnesses are gathered, the wire harnesses are further fixed to improve the stability of the wire harness fixation. Only one fixed connection point is needed to install several wire harnesses in the vehicle body, which effectively simplifies the process of wire harness fixing and improves the efficiency of wire harness fixing as well as the stability and neatness of the fixation.

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

[0019] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described below, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] See also Figure 1 、 Figure 2 and Figure 3 A car wiring harness fixing pipe clamp includes a connecting belt 1, several fixing heads 2, several limiting tightening heads 4 and a unified reinforcement head 5. The fixing head 2 is used to fix the wiring harness 3. The several fixing heads 2 fix the several wiring harnesses 3. When the connecting belt 1 is unfolded, the several fixing heads 2 are linearly and evenly arranged. The several limiting tightening heads 4 are respectively located between adjacent fixing heads 2 and fixedly installed on the connecting belt 1. At this time (that is, when the connecting belt 1 is unfolded), the wiring harness 3 can be placed in the fixing heads 2 in sequence for preliminary limiting fixation. After the wiring harness 3 is placed in the several fixing heads 2, the head and tail of the connecting belt 1 are fixedly connected together, so that the several fixing heads 2 are concentrated together and located in the connecting belt 1. During this process, as the fixing heads 2 gather, the limiting tightening heads 4 automatically limit the adjacent fixing heads 2, so that the fixing heads 2 gradually tighten and clamp the corresponding wiring harnesses 3, and before the wiring harnesses 3 are completely tightened and fixed, the wiring harnesses 3 can be adaptively or manually adjusted in position. In the process of concentrating and fixing several wiring harnesses 3, the wiring harnesses 3 are sorted to improve the neatness of several wiring harnesses 3, which is convenient for later inspection and maintenance. After the connecting belt 1 is fixed at both ends, the fixing heads 2 are uniformly controlled by the unified reinforcement head 5 to further tighten and clamp the corresponding wiring harnesses 3, while increasing the firmness of the connection between the end and end of the connecting belt 1, thereby improving the stability and reliability of the overall structure during use.

[0021] See Figure 1 、 Figure 3 and Figure 4The fixing head 2 includes a clamping fixing portion 22 with a limited end 21. The clamping fixing portion 22 is symmetrically distributed and has an arc-shaped structure. The symmetrical clamping fixing portion 22 is hinged to the connecting belt 1 at one end close to the connecting belt 1, and the other end is buckled together. During the installation process, it is only necessary to place the wire harness 3 between the symmetrical clamping fixing portions 22, and then buckle the symmetrical clamping fixing portions 22 together to quickly complete the initial limited fixation of the wire harness 3; then quickly fix the head and tail of the connecting belt 1 together, and the head and tail fixed connections of the connecting belt 1 can also be automatically buckled together by buckles; the limiting tightening head 4 is an isosceles triangle Angular structure, the number of the fixing heads 2 and the limiting tightening heads 4 are four and the fixing heads 2 and the limiting tightening heads 4 are distributed alternately in sequence, the head and tail of the connecting belt 1 are fixedly connected to form a frame-shaped concentrated area, and the fixing heads 2 and the limiting tightening heads 4 are both located in the concentrated area; in the process of connecting the head and tail of the connecting belt 1, the limiting tightening head 4 will automatically squeeze the clamping fixing part 22, so that the symmetrical clamping fixing parts 22 rotate relative to each other to clamp and fix the middle wiring harness 3, and before the wiring harness 3 is completely clamped and fixed, as the position of the fixing head 2 changes, the wiring harness 3 can adaptively or manually adjust the position state so that multiple wiring harnesses 3 can be neatly gathered and fixed together.

[0022] See Figure 1 、 Figure 3 and Figure 4 , a clamping piece 23 is connected between the ends of the symmetrical clamping and fixing parts 22 away from the connecting belt 1, and the clamping piece 23 includes a frame-shaped clamping rod 231 and a limiting frame 233 provided with a bayonet 232. The clamping rod 231 is clamped into the limiting frame 233 by the bayonet 232. When the wiring harness 3 is placed between the symmetrical clamping and fixing parts 22, the symmetrical clamping and fixing parts 22 are pressed to make the clamping rod 231 clamped into the limiting frame 233 by the bayonet 232. At this time, the wiring harness 3 is in a preliminary limited and fixed state. Afterwards, in the process of the symmetrical clamping and fixing parts 22 continuing to rotate relative to clamp and fix the wiring harness 3, the clamping rod 231 can move relative to the limiting frame 233; Figure 4 As shown, the limiting frame 233 is an elastic U-shaped frame, the bayonet 232 is a cylinder, and cylinders are provided at the ends of the two parallel sections of the elastic U-shaped frame.

[0023] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The unified reinforcement head 5 includes a base 53 provided with a locking assembly 51 and a plurality of limiting members 52. The locking assembly 51 fixes the base 53 to the 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 end 21 on the clamping fixing part 22 is limited by the limiting member 52, and the symmetrical clamping fixing part 22 is uniformly controlled to clamp the wiring harness 3. The base 53 includes a sliding member 531, a connecting member 532 and a center member 533. The center member 53 3 is symmetrically distributed front and back, and the plurality of limit members 52 are divided into two groups and are respectively installed on the symmetrical center member 533, and the limit members 52 on the center member 533 correspond one to one with the limit ends 21, the sliding member 531 and the connecting member 532 are fixedly installed on the center member 533, and the sliding member 531 is slidably connected to the limit tightening head 4 adjacent to the head end of the connecting belt 1, and the connecting member 532 corresponds to the limit tightening head 4 adjacent to the tail end of the connecting belt 1. In the process of unified reinforcement head 5, the center member is pressed 533, so that the symmetrical center piece 533 moves relatively, and the limit piece 52 on it limits the corresponding limit end 21, so that the symmetrical clamping and fixing part 22 rotates relatively, further clamping and fixing the middle wire harness 3, and the sliding piece 531 slides accordingly, and the connecting piece 532 is synchronously inserted into the corresponding limit tightening head 4 until the locking assembly 51 automatically connects the sliding piece 531 with the corresponding limit tightening head 4 and the connecting piece 532 with the corresponding limit tightening head 4. The entire wire harness 3 is fixedly installed. The process is convenient and fast, and the position of the wiring harness 3 can be flexibly adjusted during the fixing process, thereby improving the convenience of centralized fixation of multiple wiring harnesses 3 and the neatness after fixation, and correspondingly improving the convenience of later maintenance and inspection. The limiting end 21 is a limiting block with inclined surfaces symmetrically provided at the front and rear ends, and the limiting member 52 is a connecting block provided with a limiting roller. When the limiting member 52 moves with the center member 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 relative to each other.

[0024] See Figure 1 、 Figure 3 and Figure 4The connecting belt 1 includes several mounting plates 101 and several 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 the 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 one-to-one to the fixing heads 2, and the fixing heads 2 are installed on the corresponding mounting plates 101. The connecting plates 102 correspond one-to-one to the limiting tightening heads 4, and the limiting tightening heads 4 are installed on the corresponding connecting plates 102. The number of mounting plates 101 and connecting plates 102 is four. After the mounting plates 101 and the connecting plates 102 that are alternately distributed in sequence are fixedly connected together at the head and tail ends, a centralized area of ​​a rigid frame structure is formed, which is conducive to further improving the stability and reliability of the overall structure.

[0025] See Figure 1 、 Figure 2 、 Figure 3 and Figure 5The locking assembly 51 includes a base 511, a claw 512, a rotating member 513, a locking member 514 and an elastic member 515. The number of the base 511 is several, and the number of the claw 512, the rotating member 513, the locking member 514 and the elastic member 515 are two. The rotating member 513 corresponds to the claw 512 one by one. One end of the rotating member 513 is rotatably mounted on the corresponding claw 512, and the other end is located outside the concentrated area after passing through the corresponding connecting plate 102. The two claws 512 are respectively slidably mounted on the two limit 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 limit tightening head 4. The locking member 514 is fixedly mounted on the corresponding connecting plate 102, and the card seat 511 is fixedly connected to the sliding member 531 and the connecting member 532 respectively. When pressing the center member 533, the card seat 511 will pass through the claw 512 as the sliding member 531 and the connecting member 532 move and automatically engage with the corresponding claw 512. During this process, the elastic member 515 is used to initially engage the card seat 511 and the corresponding claw 512. At this time, the center member 533 can only continue to move in the direction of pressing and cannot move in the opposite direction. The locking member 514 is a convex block with a groove, and the rotating member 513 is a column with a protrusion. The card seat 511 After the corresponding claws 512 are initially engaged together, the rotating member 513 is first moved outward to further engage the claws 512 and the base 511 to ensure the stability of the engaging state of the two. Then, the rotating member 513 is rotated to align the protrusion with the groove, and then the rotating member 513 is stopped. At this time, under the action of the rebound force of the elastic member 515, the rotating member 513 will move inward to embed the protrusion in the groove, but the return distance of the rotating member 513 in this section is less than the distance the rotating member 513 moves outward, thereby improving the stability of the position state of the rotating member 513, and correspondingly improving the stability of the locked state of the locking assembly 51. During the disassembly process, It is only necessary to move the rotating member 513 outward and rotate the rotating member 513, and then press the rotating member 513 inward to separate the claw 512 from the base 511; wherein, a force-applying member 534 is fixedly connected to the center member 533, and the force-applying member 534 and the sliding member 531 are distributed on both sides of the center member 533 along the same straight line, and the connecting belt 1 is fixed with connecting hooks at both ends, and the force-applying member 534 extends from the center of the gathered wiring harness 3 to the outside. In the process of pressing the center member 533, at this time, it is only necessary to press the force-applying member 534 and the sliding member 531 synchronously from the outside of the gathered wiring harness 3 to achieve pressing of the center member 533, which is convenient for use.

[0026] See Figure 3 and Figure 4A limiting groove 54 is provided on the outer side of the clamping and fixing part 22, and the limiting tightening head 4 cooperates with the limiting groove 54 to limit the clamping and fixing part 22 in the radial and axial directions of the wire harness 3. In the process of fixing the end 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, the symmetrical clamping and fixing parts 22 are rotated relative to each other to clamp and fix the wire harness 3 in the middle, and on the other hand, the clamping and fixing parts 22 are limited in the axial direction, so that the symmetrical clamping and fixing parts 22 can stably perform the clamping and fixing work, thereby improving the stability of the fixing process of the wire harness 3.
