Description

Technical Field

[0001] This application relates to the technical field of new energy vehicles, and particularly to a wire harness limit adjustment device. Background Art

[0002] As a new type of transportation, new energy vehicles are gradually favored by the market for their environmental protection and energy-saving features. Such vehicles use unconventional vehicle fuels as the power source, or use conventional vehicle fuels but are equipped with new in-vehicle power devices, achieving innovation in vehicle power control and drive methods through advanced technologies and innovative structures. With the development of new energy vehicle technology, its power system and electrical architecture have become increasingly complex, and especially the reliability of the high-voltage electrical system has become one of the important indicators for measuring the performance of new energy vehicles.

[0003] The high-voltage inverter is one of the key components in new energy vehicles. It is responsible for converting the direct current from the battery into alternating current for use by other electrical equipment such as electric motors. To achieve this conversion, the high-voltage inverter needs to be connected to the electric motor and other electrical supporting equipment through high-voltage wire harnesses. The design of the wire harness is crucial for ensuring the safety and reliability of the electrical system. In practical applications, considering the flexibility of installation and maintenance, the wire harness often has a certain length reserved to meet the requirements of different installation positions. However, this redundant length may cause the wire harness to become scattered after installation, and usually, the excess wire harness is bundled up with cable ties for arrangement.

[0004] Although using cable ties can effectively arrange the excess wire harness, there are still some deficiencies in the actual operation process. First, when one end of the wire harness is pulled by an external force, this force will be transmitted to the plug of the wire harness, increasing the risk of the wire harness plug falling out of the socket of the high-voltage inverter. Second, the wire harness fixed with cable ties lacks an effective limit structure, resulting in the wire harness still being likely to become scattered or move in some cases. Therefore, there is an urgent need for a new solution to effectively limit the wire harness. Summary of the Utility Model

[0040] The following will describe in more detail the exemplary embodiments disclosed in the present application with reference to the accompanying drawings. Although the exemplary embodiments disclosed in the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be completely conveyed to those skilled in the art.

[0041] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application shall have the ordinary meanings understood by those skilled in the art to which this application belongs.

[0042] For the convenience of installation and maintenance, the main section (rear section) of the wire harness used to connect to the high-voltage inverter is fixed on the preset clamping structure of the vehicle body. The plug-in section (front section) of the wire harness has a certain length of usable margin, and a plug is provided at the end of the wire harness. After the plug at the end of the wire harness is inserted into the socket of the high-voltage inverter, there is still a usable margin left, that is, there is an extra wire harness section left, so that the wire harness is still in a loose state after being connected. Also, since the high-voltage inverter is connected in a loose manner with multiple wire harnesses, in order to prevent the wire harnesses from being scattered, the wire harnesses are bundled together using cable ties.

[0043] The problem caused by bundling with cable ties is that the pulling force at one end of the wire harness causes the wire harness plug to fall off or become loose from the socket of the high-voltage inverter due to the transmission of force. And, since the cable tie has no limiting function, as the vehicle travels on bumpy roads and during emergency braking, the bundled wire harnesses will shake and the cable tie will become loose. On the other hand, the transmission of the shaking force will also cause the wire harness plug to fall off or become loose from the socket of the high-voltage inverter, resulting in a failure in the electrical connection of the vehicle.

[0044] Therefore, to solve the above problems, a wire harness limiting and adjusting device is proposed. A first adjusting component and a second adjusting component are adjacently arranged on the first frame of the frame body. The first adjusting component is provided with a first clamping piece, and the second adjusting component is provided with a second clamping piece. An accommodating space is formed between the two clamping pieces, and the accommodating space is used for assembling the wire harness. The wire harness can be one or multiple.

[0045] And the first frame is further provided with a sliding component, the sliding component is connected to the second adjusting component, and can drive the second adjusting component to move along the length direction of the first frame, so as to adjust the size of the accommodating space according to the size of the outer contour of one or multiple wire harnesses, and limit and fix it to prevent it from falling off or becoming loose from the socket of the high-voltage inverter.

[0046] Embodiment 1

[0047] Refer to Att Figure 1 、 4 Referring to FIGS. 5 and 6, Embodiment 1 of the present disclosure proposes a wire harness limiting and adjusting device, which includes: a frame body 00, a first adjusting component 20, and a second adjusting component 30;

[0048] The frame body 00 includes a first frame 10, and the first frame 10 is spaced apart from the socket;

[0049] The first adjusting component 20 is rotatably arranged on the first frame 10, and the first adjusting component 20 includes a first clamping piece 21;

[0050] The second adjusting component 30 is rotatably arranged on the first housing 10. The second adjusting component 30 includes a second clamping member 31, and a receiving space 40 is formed between the first clamping member 21 and the second clamping member 31;

[0051] The sliding component 50 is arranged on the first housing 10 and can slide along the length direction of the first housing 10;

[0052] Wherein, the second adjusting component 30 is connected to the sliding component 50, and under the sliding action of the sliding component 50, the second adjusting component 30 approaches or moves away from the second adjusting component 30 to adjust the size of the receiving space 40.

[0053] Specifically, the frame body 00 provides support for other components of the wire harness limiting and adjusting device and is used for installation and connection with the high-voltage inverter 01. The installation method can be fixed connection or detachable connection. The fixed connection can adopt welding, integrally thermoforming with the housing of the high-voltage inverter, bonding, or hot melting connection, etc.; the detachable connection can be bolt 53 connection, crimping, clamping, etc. The above connection methods can all be realized by those skilled in the art and will not be elaborated here.

[0054] The cross-sectional shape of the frame body 00 is rectangular, square, rectangular with one side open, or irregular polygon, etc. After the frame body 00 is connected to the high-voltage inverter 01, at least one first housing 10 is spaced from the socket on the high-voltage inverter 01;

[0055] The first adjusting component 20 and the second adjusting component 30 are arranged adjacent to each other, and a wire harness is assembled in the assembly cavity 11 formed between the first clamping member 21 and the second clamping member 31;

[0056] And the sliding component 50 is used to move the second adjusting component 30 closer to the first adjusting component 20, so that the second clamping member 31 and the second clamping member 31 jointly apply a clamping force to the wire harness in the assembly cavity 11, thereby achieving the limiting effect of the wire harness in the assembly cavity 11;

[0057] When the wire harness is assembled in the assembly cavity 11 of the wire harness limiting and adjusting device, the plug of the wire harness is located on the side of the first housing 10 close to the high-voltage inverter 01 and is inserted into the socket arranged on the side wall of the high-voltage inverter 01. By the way that the first housing 10 is spaced from the socket on the high-voltage inverter 01, the external force received by the wire harness, such as the swinging force or external pulling force generated by the wire harness under the influence of its own gravity, is blocked outside the assembly cavity 11 formed by the first clamping member 21 and the second clamping member 31 on the first housing 10; the second clamping member 31 is clamped and cooperated with the first clamping member 21 through the sliding component 50 to firmly limit the wire harness in the assembly cavity 11 and avoid the influence of external force on the part of the wire harness close to the high-voltage inverter 01.

[0058] A wire harness limiting and adjusting device proposed by the present disclosure has a first adjusting component and a second adjusting component disposed adjacent to each other on a first frame of a frame body. The first adjusting component is provided with a first clamping member, and the second adjusting component is provided with a second clamping member. An accommodation space is formed between the two clamping members for assembling a wire harness, and the wire harness can be one or more.

[0059] Moreover, the first frame is further provided with a sliding component, which is connected to the second adjusting component and can drive the second adjusting component to move along the length direction of the first frame, so as to adjust the size of the accommodation space according to the size of the outer contour of one or more wire harnesses, limit and fix it, and prevent it from falling off or loosening from the socket of the high-voltage inverter.

[0060] Further, referring to the attached Figure 2 and 5 In some embodiments, the first adjusting component 20 further includes a first gear 22 and a first shaft 23. The first shaft 23 penetrates through the first frame 10, and both ends of the first shaft 23 are respectively fixedly connected with a first clamping member 21 and a first gear 22;

[0061] The second adjusting component 30 further includes a second gear 32 and a second shaft 33. The second shaft 33 penetrates through the first frame 10, and both ends of the first shaft 23 are respectively fixedly connected with a second clamping member 31 and a second gear 32;

[0062] Wherein, annular grooves 41 are provided on the outer peripheral sides of the first clamping member 21 and the second clamping member 31, and the openings of the annular grooves 41 face each other to form an accommodation space 40. The first gear 22 and the second gear 32 are connected by direct or indirect meshing, and the outer diameters of the first gear 22 and the second gear 32 are the same.

[0063] Specifically, during assembly or maintenance, it is necessary to adjust the length of the inserted section of the wire harness to make the wire harness have an appropriate tightness and leave an appropriate length margin, so that the wire harness will not be too loose and messy, nor will it be too tight, causing the plug to loosen or fall out of the socket under the action of external force. The existing adjustment method is to remove the cable tie and manually adjust it. This method is inefficient and inaccurate, and requires repeated debugging. In order to accurately adjust the length of the inserted section of the wire harness, that is, the length of the section of the wire harness with a plug and close to the socket, the work efficiency and installation quality are improved.

[0064] In the present disclosure, the first shaft 23 and the second shaft 33 respectively penetrate through the first frame 10. At this time, the first frame 10 is a long strip-shaped frame, and the first shaft 23 and the second shaft 33 are arranged in parallel and perpendicular to the length direction of the first frame 10. That is, if the first frame 10 is horizontally arranged, the first shaft 23 and the second shaft 33 are vertically arranged;

[0065] If the first housing 10 is vertically arranged, the first shaft rod 23 and the second shaft rod 33 are horizontally arranged.

[0066] The first clamping member 21 and the first gear 22 are coaxially arranged through the first shaft rod 23, and are respectively located on both sides of the first housing 10;

[0067] The second clamping member 31 and the second gear 32 are coaxially arranged through the second shaft rod 33, and are respectively located on both sides of the first housing 10;

[0068] Both the first clamping member 21 and the second clamping member 31 are circular wheel members, specifically, they can be roller members, and an annular groove 41 is circumferentially arranged on the outer side of the roller member. The openings of the two annular grooves 41 face each other to form an accommodating space 40; the cross-sectional shapes of the two openings can be rectangular, circular or oval for accommodating the wire harness. Among them, an annular rubber ring is arranged in the annular groove 41, which can be made of rubber or silica gel material, to increase the friction force with the outer side of the wire harness. The rubber ring will also undergo a certain deformation when compressed, and protect the wire harness through a certain degree of deformation of the rigid extrusion force to avoid damage to the skin of the wire harness.

[0069] Since the first gear 22 and the second gear 32 are meshed and have the same outer diameter, when any one of the gears rotates, it can drive the other gear to rotate synchronously. Moreover, the first clamping member 21 and the second clamping member 31 also rotate synchronously, and drive the wire harness in the accommodating space 40 to move, so that the length margin of the wire harness insertion section can be adjusted flexibly and accurately.

[0070] Further, referring to the appendix Figures 4-5 , in some embodiments, the first gear 22 and the second gear 32 are directly meshed and connected, and the wire harness limiting and adjusting device further includes a driving part, and the driving part is connected to the first gear 22 or the second gear 32.

[0071] Specifically, in order to realize the synchronous rotation of the first clamping member 21 and the second clamping member 31 to adjust the length of the wire harness, in the technical solution adopted in this application, the first gear 22 and the second gear 32 are directly meshed, and a driving part is provided to drive any one of the gears to rotate.

[0072] Among them, the driving part can be a protrusion or a hand crank arranged on the side of the first gear 22 or the second gear 32. The protrusion or the hand crank is manually shaken to realize the driving rotation of the gear. The advantage of manual operation is that it can be precisely controlled and is easy to adjust.

[0073] The driving part can also be a driving motor, which is arranged on the first housing 10, and the output end of the motor is meshed with the first gear 22 to drive the first gear 22 to rotate, and the first gear 22 drives the second gear 32 to rotate. The advantage of using a driving motor to drive is high automation, fast and labor-saving.

[0074] Further, referring to Appendices Figure 1 and 2 6, in some embodiments, the first gear 22 and the second gear 32 are indirectly meshed and connected. Both the first gear 22 and the second gear 32 are worm gears. The wire harness limiting and adjusting device further includes a worm 60. The worm 60 is disposed between the first gear 22 and the second gear 32 and is meshed and connected with the first gear 22 and the second gear 32 respectively disposed on both sides.

[0075] Specifically, in order to realize the synchronous rotation of the first clamping member 21 and the second clamping member 31 so as to adjust the length of the wire harness, in the technical solution adopted in the present application, the driving principle of the worm and worm gear 60 can also be adopted. Both the first gear 22 and the second gear 32 are set as worm gears and are spaced apart from each other. An installation bracket is added to the first housing 10 so that the worm 60 is rotatably disposed on the installation bracket through a bearing, and one end extends between the first gear 22 and the second gear 32 and meshes with the two gears. The other end is provided with a handle for conveniently screwing the worm 60. When the worm 60 rotates, the two gears rotate synchronously and in opposite directions, one is counterclockwise and the other is clockwise. The torque of the worm and worm gear 60 is large. When the first clamping member 21 and the second clamping member 31 tightly clamp the wire harness and rotate, the accuracy of adjusting the wire harness can be improved. The length of the outer diameter rotation of the first clamping member 21 or the second clamping member 31 is equal to the length of the wire harness adjustment.

[0076] Further, referring to Appendices Figure 2 and 5 , in some embodiments, an assembly cavity 11 is provided along the length direction inside the first housing 10, and the axis of the assembly cavity 11 is collinear with the axis of the first housing 10 and is set as the first axis;

[0077] The sliding assembly 50 includes a slider 51. The slider 51 is slidably disposed in the assembly cavity 11 and can reciprocate along the axis;

[0078] The slider 51 is provided with a through hole. The axis of the through hole is the second axis. The second shaft rod 33 passes through the through hole and can rotate in the through hole.

[0079] Specifically, in order to enable the first clamping member 21 and the second clamping member 31 to clamp wire harnesses of different thicknesses, one or more wire harnesses can be clamped, so that the second adjusting assembly 30 can move away from or close to the first adjusting assembly 20, thereby changing the size of the accommodation space 40 between the first clamping member 21 and the second clamping member 31. For example, the farther the second adjusting assembly 30 is from the first adjusting assembly 20, the larger the accommodation space 40 is.

[0080] In the technical solution adopted in this application, an assembly cavity 11 is provided inside the first housing 10. The assembly cavity 11 is a strip-shaped cavity, and a slider 51 is installed inside. The slider 51 can be in clearance fit with the assembly cavity 11 and move along the length direction of the strip-shaped assembly cavity 11. The slider 51 can be circular or rectangular, and the specific structural form is not limited. The slider 51 is provided with a through hole for the second shaft rod 33 to pass through, and the second shaft rod 33 is in clearance fit with the through hole and can rotate in the through hole. Long strip openings are respectively provided on both side walls of the first housing 10 along the length direction of the assembly cavity 11. The openings are communicated with the assembly cavity 11 for the second shaft rod 33 to extend from the openings on both sides to the outside of the assembly cavity 11, and a second clamping member 31 and a second gear 32 are respectively arranged at both ends. The size of the accommodating space 40 is changed by the movement of the slider 51 in the assembly cavity 11.

[0081] Further, referring to the appendix Figures 2-3 , in some embodiments, the sliding assembly 50 further includes a spring member 52. The spring member 52 is arranged in the assembly cavity 11, and both ends extend in opposite directions. One end is fixedly connected to the slider 51, and the other end abuts against the inner top wall of the assembly cavity 11.

[0082] Specifically, in order to enable the second clamping member 31 to apply a tightening force to the first clamping member 21, in the technical solution adopted in this application, the spring member 52 is used to apply the tightening force. The spring member 52 can be a compression spring or a disc spring.

[0083] The spring member 52 is assembled in the assembly cavity 11, one end abuts against the inner top wall, and the other end is fixed on the slider 51, providing an elastic supporting force for the slider 51, so that the slider 51 is placed on the inner bottom wall of the assembly cavity 11 when not subjected to external force. At this time, the second clamping member 31 is close to the first clamping member 21; when the wire harness is placed in the accommodating space 40 between the second clamping member 31 and the first clamping member 21, the spring member 52 is squeezed and deformed, generating an elastic force to make the second clamping member 31 abut against the wire harness and cooperate with the first clamping member 21 to tightly clamp the wire harness. When the vehicle travels on a bumpy road section or brakes frequently and emergently, the wire harness swings and shakes, and the generated force will be absorbed by the deformation of the spring member, and the wire harness plug will not be affected, thereby improving the stability of the plug-in.

[0084] Further, referring to the appendix Figure 5 , in some embodiments, the first housing 10 is provided with a threaded hole 12. The threaded hole 12 is communicated with the assembly cavity 11, and the axis of the threaded hole 12 is collinear with the first axis;

[0085] The sliding assembly 50 further includes a bolt 53. One end of the bolt 53 passes through the threaded hole 12 and enters the assembly cavity 11 and is rotatably connected to the slider 51, and the other end is placed outside the assembly cavity 11.

[0086] Specifically, in order to achieve the second clamping member 31 applying pressure to the first clamping member 21, in the technical solution adopted in this application, the sliding assembly 50 further includes a bolt 53. By opening a threaded hole 12 in the first housing 10, which can be an internal thread or an external thread structure, and making the threaded hole 12 communicate with the assembly cavity 11, the bolt 53 is in threaded engagement with the threaded hole 12, and one end enters the assembly cavity 11 and is connected to the slider 51. The connection method can be that a bearing is provided on the end face where the slider 51 is connected to the bolt 53, and one end of the bolt 53 is in interference fit with the inner ring of the bearing, so as to rotate flexibly relative to the slider 51 to achieve a rotational connection;

[0087] The other end of the bolt 53 is placed outside the assembly cavity 11. By rotating the other end of the bolt 53, the position of the slider 51 in the assembly cavity 11 is adjusted, so as to adjust the size of the accommodation space 40 between the second clamping member 31 and the first clamping member 21, and make the second clamping member 31 approach the first clamping member 21 to apply pressure to the wire harness in the middle.

[0088] Further, referring to Atta Figure 3 In some embodiments, a first guiding structure is provided on the inner sidewall of the assembly cavity 11 along the length direction; a second guiding structure 511 is provided on the outer sidewall of the slider 51, and the second guiding structure 511 is correspondingly arranged in cooperation with the first guiding structure.

[0089] Specifically, in order to achieve the stable movement of the slider 51 in the assembly cavity 11, so that the second adjusting assembly 30 moves stably relative to the first adjusting assembly 20, and stably adjusts the second clamping member 31, so that the second clamping member 31 and the first clamping member 21 cooperate to firmly clamp the wire harness.

[0090] A first guiding structure is provided on the inner sidewall of the assembly cavity 11, and a second guiding structure 511 is provided on the outer sidewall of the slider 51. The two cooperate to achieve the stable movement of the slider 51.

[0091] Among them, the first guiding structure is a chute or a slide rail provided on the inner sidewall of the assembly cavity 11, and there is at least one chute or slide rail; it can also be two, which are arranged oppositely on the inner sidewall of the assembly cavity 11;

[0092] The second guiding structure 511 is a convex block or a groove provided on the outer sidewall of the slider 51. There is at least one convex block or groove, and there are also two. The setting positions of the convex block or groove correspond to the positions of the first guiding structure.

[0093] If it is a convex block, it cooperates with the chute on the inner sidewall of the assembly cavity 11; if it is a groove, it cooperates with the slide rail on the inner sidewall of the assembly cavity 11.
