Technical Field

[0001] The invention relates to the technical field of automobile wiring harnesses, and more specifically, to a wiring harness dedicated to an automobile air-conditioning control chip. Background Art

[0002] As an indispensable means of transportation in modern society, the definition and function of automobiles have been constantly evolving with the advancement of science and technology. From the initial internal combustion engine cars to today's electric cars, the history of automobile development has witnessed mankind's unremitting efforts in the pursuit of speed and efficiency. Cars are not only a means of personal travel, but also an important driving force for cargo transportation and social and economic development.

[0003] The dedicated wiring harness for automotive air conditioning control chips is a collection of electrical lines used to connect the control chip and other components in the automotive air conditioning system.

[0004] However, the existing internal structure of automobiles is compact, and the space provided for various devices and wiring harnesses is limited. When laying out the wiring harness in such a complex environment, the air-conditioning control chip wiring harness will have corner bends in certain areas. At this time, the corner bends will present a right angle, but when the wiring harness is bent at a right angle, the internal wires may change in relative position, which will cause the coupling capacitance between the wires to change. At the same time, during the right-angle bending process, the wiring harness material will be subjected to certain mechanical stress, which may cause changes in the physical properties of the material, such as resistance, inductance, etc., and thus affect electromagnetic compatibility, resulting in the right-angle bends of the wiring harness during layout and routing, which will increase electromagnetic interference.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a dedicated wiring harness for an automobile air-conditioning control chip. Summary of the invention

[0006] In view of the deficiencies in the prior art, the object of the present invention is to provide a wiring harness dedicated to an automobile air-conditioning control chip.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wiring harness dedicated to an automobile air-conditioning control chip, comprising a wiring harness, and also comprising: a layout component arranged at a corner of the wiring harness, the layout component comprising a support rod, a baffle, a spring A, a splint, a protective pad and an annular groove, the surface of the support rod is in a smooth ring shape, and the baffles are symmetrically inserted on the support rod, and an annular groove with a smooth curved surface is presented between the two baffles and the support rod, one end of a plurality of springs A are installed on the sides of the two baffles that are close to each other, all the springs A on each baffle are arranged as a group, the other end of each group of springs A is connected to a splint, and the sides of the two splints that are close to each other are installed with a protective pad.

[0008] Preferably, a stabilizing component is provided on the support rod, and the stabilizing component includes a support plate, a spring B, a pressure plate, an anti-skid pad and an anti-skid groove. A support plate is installed on the support rod at the corner corresponding to the wiring harness, and multiple pressure plates are slidably installed on the support plate. Each of the pressure plates is connected to the support plate by multiple springs B, and each pressure plate is installed with an anti-skid pad on a side away from the support plate, and each of the anti-skid pads is provided with multiple anti-skid grooves on a side away from the support plate, which is convenient for improving the stability of the wiring harness, and can effectively reduce the shaking and friction of the wiring harness during the operation of the vehicle, thereby reducing the generation of electromagnetic interference, which is of great significance for ensuring the stable operation of the automotive electronic system.

[0009] Preferably, the wiring harness is slidably installed between the annular grooves, so that the corners of the wiring harness are smoothly curved, which can effectively reduce electromagnetic interference.

[0010] Preferably, the two clamps are in a smooth curved shape, and each of the protection pads is in the same smooth curved shape as the clamps, so as to better adapt to the wiring harness and disperse the vibration energy generated during the operation of the vehicle, thereby improving the stability of the wiring harness.

[0011] Preferably, the support plate is in a ring shape, each of the pressure plates is in an arc shape, each of the anti-slip pads is in an arc shape consistent with the shape of the pressure plate on which it is located, each of the pressure plates corresponds to the corner of the wiring harness, and each pressure plate corresponds to the center position of the annular groove, so as to better fit the wiring harness and improve the stability of the wiring harness.

[0012] Preferably, each of the pressure plates is evenly and equidistantly distributed on the support plate to ensure that the wiring harness is subjected to balanced pressure over its entire length. At the same time, the wiring harness can be more effectively fixed to prevent it from loosening or shifting during operation, thereby avoiding electromagnetic interference caused by loosening or shifting.

[0013] Preferably, each of the anti-skid grooves is wavy in shape, so as to increase friction and disperse stress concentration, thereby improving the stability of the wiring harness.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, by setting a layout component at the corner of the wiring harness, the two clamps are moved in opposite directions. At this time, each clamp will compress all the connected springs A. When the two clamps are opened, the wiring harness is installed in the annular groove. At this time, the corner of the wiring harness will present a smooth curve. Then the two clamps are released. At this time, each spring A will push the two clamps toward the wiring harness through resilience and firmly clamp the corner of the wiring harness. At the same time, when the two clamps move toward the wiring harness, they will move toward the wiring harness with two protective pads. At this time, the two protective pads will fit tightly with the corner of the wiring harness. At the same time, the two clamps will clamp the corner of the wiring harness in the middle of the annular groove, thereby solving the problem in the background technology that the right-angle bend of the wiring harness during layout and routing will increase electromagnetic interference.

At this time, each spring B will push the corresponding pressing plate toward the upper end of the wiring harness corner through resilience. At the same time, each pressing plate will firmly press the wiring harness in the annular groove. At this time, each pressing plate will be at the center position of the upper end of the wiring harness corner. When each pressing plate moves toward the wiring harness, it will move toward the wiring harness with the installed anti-skid pad until each anti-skid pad is attached to the wiring harness. When each anti-skid pad is attached to the wiring harness, the protective groove on each anti-skid pad will also be attached to the wiring harness. In this way, the wiring harness is firmly pressed into the annular groove by each pressing plate to be fixed. This can effectively reduce the shaking and friction of the wiring harness during the operation of the vehicle, thereby reducing the generation of electromagnetic interference, which is of great significance for ensuring the stable operation of the automotive electronic system.

[0024] like Figure 1-5 As shown, the present invention provides a dedicated wiring harness for an automobile air-conditioning control chip, including a wiring harness 1, which is used to connect various components and sensors in an air-conditioning system and transmit power, signals and data, and also includes: a layout component 2 arranged at the corner of the wiring harness 1, which is used to achieve that the corner of the wiring harness 1 is smoothly curved by installing the wiring harness 1 in an annular groove 206, and then the two clamping plates 204 and the protective pads 205 on the two clamping plates 204 are pushed toward the corner of the wiring harness 1 by the resilience of each spring A203, so as to achieve the smooth curve at the corner of the wiring harness 1 and firmly fix the wiring harness 1 in the annular groove 206, reduce the reflection and scattering of electromagnetic waves at the corner, thereby reducing the generation of electromagnetic interference, and can also ensure that the wiring harness 1 is evenly and stably fixed at the corner, which helps to prevent the wiring harness 1 from loosening or falling off due to vibration or external force during operation, thereby reducing the electromagnetic interference caused by loosening or falling off;

[0025] The layout component 2 includes a support rod 201, a baffle 202, a spring A203, a clamping plate 204, a protective pad 205 and an annular groove 206. The surface of the support rod 201 is in a smooth ring shape, which is used to facilitate the wiring harness 1 to present a smooth curved corner, and the baffles 202 are symmetrically inserted on the support rod 201, which is used to facilitate the placement of the wiring harness 1. A smooth curved annular groove 206 is presented between the two baffles 202 and the support rod 201, which is used to facilitate the wiring harness 1 to be confined in the annular groove 206 and can also make the corner of the wiring harness 1 present a smooth determination, effectively reducing the effect of electromagnetic interference, and one end of a plurality of springs A203 are installed on the side of the two baffles 202 close to each other, which is used to automatically push the two clamping plates 204 Towards the wire harness 1 and aligning the wire harness 1 and pushing the wire harness 1 to the middle of the annular groove 206, all springs A203 on each baffle 202 are set as a group, and the other end of each group of springs A203 is connected with a clamping plate 204, which is used to firmly fix the wire harness 1 at a predetermined position, reduce the loosening or falling off of the wire harness 1 caused by vibration or external force, and this stability can reduce electromagnetic interference. At the same time, the clamping plate 204 itself may also have a certain shielding function, further reducing the influence of the external electromagnetic field on the wire harness 1. The two clamping plates 204 are installed with protective pads 205 on the sides close to each other, which are used to effectively absorb and disperse the vibrations generated during the driving of the vehicle, reduce the transmission of these vibrations to the wire harness 1, and reduce the risk of wear, looseness or even breakage of the wire harness 1 caused by vibration;

[0026] The two clamps 204 are in a smooth curved shape, which is used to better adapt to the natural bending of the wire harness 1 at the corners, avoid excessive stress concentration at the corners of the wire harness 1, and can fit the wire harness 1 more closely to provide a more uniform and stable fixing force. Each protective pad 205 is in the same shape as the clamp 204 and is in a smooth curved shape. It is used to fit the curved contour of the wire harness 1 more closely, which helps to reduce the gap between the wire harness 1 and the clamp 204, thereby reducing the friction and wear caused by vibration or external force. In addition, the arc design helps to better absorb and disperse the vibration energy generated during the operation of the vehicle, thereby extending the service life of the wire harness 1.

[0027] The support rod 201 is provided with a stabilizing component 3, which is used to push all the pressing plates 303 and the anti-skid pads 304 on each pressing plate 303 to the corner of the wiring harness 1 through each spring B302. At this time, each pressing plate 303 can firmly fix the wiring harness 1 in the annular groove 206, and the wavy anti-skid grooves 305 on each anti-skid pad 304 can further increase the friction force, so as to firmly press the wiring harness 1 in the annular groove 206 to fix it, which can effectively reduce the shaking and friction of the wiring harness 1 during the operation of the car, thereby reducing the generation of electromagnetic interference, which is of great significance for ensuring the stable operation of the automotive electronic system;

[0028] The stabilizing component 3 includes a support plate 301, a spring B302, a pressure plate 303, an anti-skid pad 304 and an anti-skid groove 305. A support plate 301 is installed at the corner of the support rod 201 corresponding to the wiring harness 1, which is used to support each spring B302. A plurality of pressure plates 303 are slidably installed on the support plate 301, which are used to fix the wiring harness 1. Each pressure plate 303 is connected to the support plate 301 by a plurality of springs B302, which are used to push each pressure plate 303 toward the wiring harness 1, and an anti-skid pad 304 is installed on one side of each pressure plate 303 away from the support plate 301, which is used to increase the friction force. A plurality of anti-skid grooves 305 are provided on one side of each anti-skid pad 304 away from the support plate 301, which are used to further increase the friction force, and can effectively make the limit more stable.

[0029] The support plate 301 is in a ring shape, which is used to enable each spring B302 to be in an arc shape when installed on the support plate 301. Each pressure plate 303 is in an arc shape, which is used to achieve a more even dispersion of the pressure applied to the corners of the wiring harness 1, avoiding excessive stress concentration at a single position, thereby extending the service life of the wiring harness 1. At the same time, the arc design enables the pressure plate 303 to better fit the wiring harness 1, providing a more stable and reliable fixation. This fixation method helps prevent the wiring harness 1 from loosening or shifting during operation, thereby reducing electromagnetic interference caused by loosening or shifting. Each anti-slip pad 304 is consistent with the shape of the pressure plate 303 and is in an arc shape. It is used to increase the contact area with the surface of the wiring harness 1, thereby providing greater friction. This enhanced friction helps prevent the wiring harness 1 from sliding during operation. or shift, so as to improve the stability of the wiring harness 1, and the arc-shaped anti-skid pad 304 has a certain elasticity and softness, which can absorb and disperse the vibration energy generated during the operation of the vehicle. By effectively reducing shock, the impact of vibration on the internal wires of the wiring harness 1 can be reduced, and the service life of the wiring harness 1 can be effectively extended. Each pressing plate 303 corresponds to the corner of the wiring harness 1, which is used to facilitate accurate pressing of the wiring harness 1, and each pressing plate 303 corresponds to the center position of the annular groove 206, which is used to achieve more uniform application of the fixing force to the entire wiring harness 1. This uniform pressure distribution helps to reduce damage to the wiring harness 1 caused by excessive local pressure, and by applying pressure at the center position, the pressing plate 303 can more effectively prevent the wiring harness 1 from loosening or shifting during operation. This stable fixing method can improve stability;

[0030] Each pressing plate 303 is evenly and equidistantly distributed on the supporting plate 301, and is used to ensure that the wire harness 1 is subjected to balanced pressure over the entire length. This balanced force mode helps to reduce damage to the wire harness 1 caused by excessive local pressure, and can more effectively fix the wire harness 1 to prevent it from loosening or shifting during operation, thereby avoiding electromagnetic interference caused by loosening or shifting;

[0031] Each anti-skid groove 305 is wavy in shape, and is used to form more tiny concave-convex structures between the wiring harness 1 and the contact surface, thereby significantly increasing the friction. The enhanced friction helps prevent the wiring harness 1 from sliding or shifting during operation, ensuring stability and reliability. At the same time, the wavy anti-skid groove 305 has a certain elasticity and softness, and can absorb and disperse the vibration energy generated during the operation of the vehicle. By effectively reducing shock, it can reduce the impact of vibration on the internal wires of the wiring harness 1 and extend its service life.

[0032] The wire harness 1 is slidably installed between the annular grooves 206, which is used to achieve a smooth curved shape at the corner of the wire harness 1, which can effectively reduce electromagnetic interference.

[0033] Working principle: When installing the wire harness 1 at a corner, first move the two clamps 204 in opposite directions. At this time, each clamp 204 will compress all the connected springs A203. When the two clamps 204 are opened, the wire harness 1 is installed in the annular groove 206. At this time, the corner of the wire harness 1 will present a smooth curve. Then release the two clamps 204. At this time, each spring A203 will push the two clamps 204 to the wire harness 1 through resilience and grab the wire harness 1 and turn it. At the same time, when the two clamping plates 204 move toward the wire harness 1, they will carry the two protection pads 205 to move toward the wire harness 1. At this time, the two protection pads 205 will fit tightly with the corners of the wire harness 1. At the same time, the two clamping plates 204 will clamp the corners of the wire harness 1 in the middle of the annular groove 206. When the two clamping plates 204 move in opposite directions, each pressing plate 303 will move toward the supporting plate 301 at the same time. At this time, each pressing plate 303 will press the connected spring B302. When the wire harness 1 is installed in the annular groove and clamped by the two clamping plates 204, each pressing plate 303 will be released. At this time, each spring B302 will push the corresponding pressing plate 303 to the upper end of the corner of the wire harness 1 through resilience. At the same time, each pressing plate 303 will firmly press the wire harness 1 in the annular groove 206. At this time, each pressing plate 303 will be at the center of the upper end of the corner of the wire harness 1. When each pressing plate 303 moves toward the wire harness 1, it will bring the installed anti-slip pad 304 to the wire harness 1. Move until each anti-skid pad 304 is in contact with the wiring harness 1. When each anti-skid pad 304 is in contact with the wiring harness 1, the protective groove on each anti-skid pad 304 will also be in contact with the wiring harness 1, so that the wiring harness 1 can be firmly pressed into the annular groove 206 by each pressing plate 303 to be fixed, which can effectively reduce the shaking and friction of the wiring harness 1 during the operation of the car, thereby reducing the generation of electromagnetic interference, which is of great significance for ensuring the stable operation of the automotive electronic system.
