Abstract
Description
Technical Field
[0001] This application relates to the technical field of electrical appliances, and particularly to a wire harness fixing device. Background Art
[0002] When a wire harness needs to be connected to a rotatable component and supply power to it, the wire harness needs to rotate accordingly. To avoid interference with other components when the wire harness rotates with the rotatable component, it is usually necessary to limit the wire harness. Currently, the wire harnesses connected to the rotating structure are mainly divided into two connection methods: one is that the wire harness is led out inside the rotating shaft or in its adjacent area. For example, the wire harness of the refrigerator door body is led out, or the wire harness layout at the rotating shaft of the laptop computer; the other is that the wire harness is arranged along a direction perpendicular to the rotating shaft. For example, the wire routing of the car door body, or the wire harness layout of the embedded dishwasher door body.
[0003] However, both of these two connection methods pose relatively high technical requirements for the layout environment of the wire harness and the performance of the wire harness itself. The first method requires that there must be sufficient space inside the rotating shaft or the wire harness itself must be thin enough, and the wire harness also needs to withstand the possible torsional force applied. The second method requires a large bending space, and the wire harness must have excellent bending resistance performance. Summary of the Utility Model
[0004] Based on this, in view of the problem that the wire harness connected to the rotating structure in the prior art is not applicable to narrow spaces and requires high bending resistance and torsional resistance, it is necessary to provide a wire harness fixing device.
[0005] A wire harness fixing device, the wire harness fixing device includes a wire harness, a fixing member, and a rotating member. The rotating member can rotate relative to the fixing member around a rotation axis. The fixing member is provided with a fixing block, and the fixing block is located on the left or right side of the rotating member. The wire harness includes a fixed end and a moving end. The fixed end is connected to the fixing block, and the moving end is connected to the rotating member and the axis of the moving end is arranged at an angle to the rotation axis.
[0006] In one embodiment, the range of the angle between the axial direction of the fixed end and the rotation axis is 0° - 15°.
[0007] In one embodiment, the axial direction of the fixed end is parallel to the rotation axis.
[0008] In one embodiment, the fixing block is provided with a wire passing hole for the wire harness to pass through, and the axis of the wire passing hole is parallel to the rotation axis.
[0009] In one embodiment, the range of the angle between the axis of the moving end and the rotation axis is 75° - 90°.
[0010] In one embodiment, the axis of the moving end is perpendicular to the rotation axis.
[0011] In one embodiment, the fixing member includes a fixing surface for setting the fixing block, and the fixing surface is parallel to the rotation axis.
[0012] In one embodiment, the wire harness further includes a bent section, and the fixed end and the moving end are respectively located at both ends of the bent section. During the rotation of the rotating member relative to the fixing member, the bent section bends and twists.
[0013] In one embodiment, the height of the lowest point of the bent section during the rotation of the rotating member is lower than the heights of the fixed end and the moving end of the wire harness.
[0014] In one embodiment, the diameter of the wire harness is D. In the direction of the rotation axis, the minimum distance A between the axis of the moving end and the fixing member satisfies A≥5D and A≤150mm.
[0015] In one embodiment, the diameter of the wire harness is D. In the direction perpendicular to the fixing surface, during the rotation of the rotating member relative to the fixing member, the maximum distance C between the axis of the fixed end and the bent section satisfies D≤C≤3D, ensuring that there is always a reasonable length of bending amount in the wire harness during the rotation process, and avoiding the wire harness from being straightened to generate local large stress and making the wire harness easily damaged.
[0016] In one embodiment, the range between the highest point and the lowest point of the bent section during the rotation of the rotating member is the rotation range of the rotating member. In the direction perpendicular to the rotation axis and parallel to the fixing surface, the axis of the fixed end is located within the rotation range of the rotating member.
[0017] In one embodiment, in the direction perpendicular to the rotation axis and parallel to the fixing surface, the axis of the fixed end is located at the center of the rotation range of the rotating member.
[0018] In one embodiment, in the direction perpendicular to the rotation axis and parallel to the fixing surface, during the rotation of the rotating member relative to the fixing member, the swinging length of the bent section is B, where |B - A|<1 / 3A and |B - A|<1 / 3B.
[0019] In one embodiment, B = A.
[0020] In the wire harness fixing device provided in the above solution, one end of the wire harness is fixed parallel to the rotation axis, and the other end is arranged at an angle with the rotation axis and rotates synchronously with the rotating member. When the rotating member rotates, the wire harness bends and twists between the fixed end and the moving end. At the same time, by utilizing the bending strength and torsional strength of the wire harness, the wire harness fixing device can be applied to a narrow space and has relatively low requirements for the single performance (bending strength or torsional strength) of the wire harness. For common wire harnesses, their bending strength and torsional strength are both within a certain range. If the requirements for the single performance of the wire harness are high, multiple twists or bends will cause the wire harness to break. By simultaneously utilizing the bending strength and torsional strength of the wire harness, compared with the bending strength and torsional strength required for using the single performance of the wire harness, both are lower, thus avoiding the wire harness from being twisted or broken and ensuring the stability and durability of the wire harness during use.

[0035] This application provides a dishwasher, including a door body as described in the following embodiments, and further including an inner container provided with a cleaning cavity. The door body covers the inner container and jointly encloses a cleaning cavity with the inner container.
[0036] This application also provides a door body, which can be applied to the dishwasher as described above, or can also be applied to any existing electrical appliance, such as a washing machine, a dryer, etc. The door body includes a flip screen assembly 10 as described in the following embodiments. The flip screen assembly 10 can be used to display the cleaning working hours and cleaning status.
[0037] Refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 show schematic structural diagrams of the flip screen assembly 10 in different states in an embodiment of this application. The flip screen assembly 10 provided in an embodiment of this application can be connected to the top of the door body, used to display the working status and working time, or can also be directly installed on the main body part of the electrical appliance. As Figure 1 and Figure 2 shown, the flip screen assembly 10 includes a wire harness fixing device 100 as described in any of the following embodiments, and further includes a screen assembly 200. The screen assembly 200 is rotatably arranged around a rotation axis, and the screen assembly 200 has an open state as shown in Figure 1 and a closed state as shown in Figure 2 .
[0038] Combined with Figure 3 and Figure 4 shown,Figure 3 and Figure 4 FIG. Figure 4 and FIG. respectively show schematic structural diagrams of different states of the wire harness fixing device 100 in an embodiment of the present application. A wire harness fixing device 100 provided in an embodiment of the present application will be described by taking the wire harness fixing device 100 applied to the above-mentioned flip screen assembly 10 as an example, but it is not limited thereto. The wire harness fixing device 100 can also be applied to other scenarios where power needs to be supplied to a rotating member, such as a car door rotatably connected to a car body.
[0039] The wire harness fixing device 100 includes a wire harness 130, a fixing member 110, and a rotating member 120. The rotating member 120 can rotate relative to the fixing member 110 around a rotation axis. The screen assembly 200 is connected to the rotating member 120 and rotates synchronously. Optionally, the rotating member 120 can be integrated with the screen assembly 200, and is integrally formed with a part of the structure inside the screen assembly 200 to rotate synchronously. At this time, the rotating member 120 can be regarded as a part of the screen assembly 200. In other embodiments, the screen assembly 200 can also be fixedly connected to the rotating member 120. The screen assembly 200 is rotatably connected to the fixing member 110 around the rotation axis, and the maximum angle and the minimum angle of the rotating member 120 relative to the fixing member 110 respectively correspond to the opening and closing of the screen assembly 200. Figures 1 to 4 When the screen assembly 200 is in the open state as shown in Figure 1 FIG. Figure 1 , the rotating member 120 is at the maximum angle of rotation relative to the fixing member 110 as shown in Figure 3 FIG. Figure 3 . When the screen assembly 200 is in the closed state as shown in Figure 2 FIG. Figure 2 , the rotating member 120 is at the minimum angle of rotation relative to the fixing member 110 as shown in Figure 4 FIG. Figure 4 . For the convenience of description, the position of the rotating member 120 corresponding to the open state of the screen assembly 200 is defined as the first position, the position of the rotating member 120 corresponding to the state between the open state and the closed state of the screen assembly 200 is defined as the second position, and the position of the rotating member 120 corresponding to the closed state of the screen assembly 200 is defined as the third position. Obviously, the second position is located between the first position and the third position.
[0040] As shown in Figure 3 and Figure 4 FIG. Figure 3 and FIG. Figure 4 , the fixing member 110 is provided with a fixing block 140. The fixing block 140 is located on one side in the axial direction parallel to the rotation axis, that is, the fixing block 140 is located on the left or right side of the rotating member 120. In this embodiment, the fixing block 140 is located on the left side of the part of the rotating member 120 for connecting the wire harness 130. In other embodiments, the fixing block 140 can also be located on the right side of the rotating member 120.
[0041] As shown in Figure 3 and Figure 4As shown, the wire harness 130 includes a fixed end 131 and a moving end 132. The fixed end 131 is connected to the fixed block 140, and the moving end 132 is connected to the rotating member 120. The axis of the moving end 132 is arranged at an angle to the rotation axis. When the rotating member 120 rotates, the wire harness 130 bends and twists between the fixed end 131 and the moving end 132. At the same time, by utilizing the flexural strength and torsional strength of the wire harness 130, the wire harness fixing device 100 can be applied to a narrow space, and the requirement for the single performance (flexural strength or torsional strength) of the wire harness 130 is relatively low. For common wire harnesses 130, their flexural strength and torsional strength are both within a certain range. If the requirement for the single performance of the wire harness 130 is relatively high, multiple twists or bends will cause the wire harness 130 to break. By simultaneously utilizing the flexural strength and torsional strength of the wire harness 130, compared with the flexural strength and torsional strength required for utilizing the single performance of the wire harness 130, both are lower, thus avoiding the wire harness 130 from being twisted or broken, and ensuring the stability and durability of the wire harness 130 during use.
[0042] As Figure 3 and Figure 4 shown, the wire harness 130 further includes a bent section 133. The fixed end 131 and the moving end 132 are respectively located at both ends of the bent section 133. During the process of the rotating member 120 rotating relative to the fixed member 110, the bent section 133 bends and twists to prevent the fixed end 131 and the moving end 132 from falling off, so that the wire harness 130 maintains a state where both ends are limited.
[0043] As Figure 3 or Figure 4 shown, the included angle range between the axis of the fixed end 131 and the rotation axis is 0° - 15°, so that a small included angle is formed between the axis of the fixed end 131 and the rotation axis. Furthermore, when the rotating member 120 rotates, the wire harness 130 bends and undergoes a small degree of torsion at the fixed end 131. In this embodiment, the axis of the fixed end 131 is parallel to the rotation axis, so that when the rotating member 120 rotates, the wire harness 130 bends at the fixed end 131 while reducing the torsional force.
[0044] In one embodiment, the fixed block 140 is provided with a threading hole 141 for the wire harness 130 to pass through, and the axis of the threading hole 141 is parallel to the rotation axis. In other embodiments, the fixed block 140 may also be provided with a snap structure for clamping the wire harness 130.
[0045] In one embodiment, the angle range between the axis of the moving end 132 and the rotation axis is 75° - 90°, so that when the rotating member 120 rotates, the wire harness 130 can swing along with the rotation of the rotating member 120. In one embodiment, the axis of the moving end 132 is perpendicularly arranged to the rotation axis. In other embodiments, the axis of the moving end 132 can also be inclined at other angles to the rotation axis. For example, the angle between the axis of the moving end 132 and the rotation axis is 60° - 75°.
[0046] As Figure 3 and Figure 4 shown, in one embodiment, the fixing member 110 includes a fixing surface 111 for arranging the fixing block 140. The fixing surface 111 is parallel to the rotation axis, that is, the rotation plane of the rotating member 120 is perpendicular to the fixing surface 111.
[0047] As Figure 5 shown, in some embodiments, the height of the lowest point of the bending section 133 during the rotation of the rotating member 120 is lower than the heights of the fixed end 131 and the moving end 132 of the wire harness 130. Since the directions of the fixed end 131 and the moving end 132 are inconsistent, the two ends of the bending section 133 are connected in different directions, causing the bending section 133 to bend. In this embodiment, the bending section 133 can be lower than the height of the moving end 132 to prevent the bending section 133 connected between the fixed end 131 and the moving end 132 from being tensioned and subjected to a large bending force, and to prevent the wire harness 130 from being overstressed and easily broken.
[0048] It can be understood that in the direction of the rotation axis, the greater the distance between the axis of the moving end 132 and the fixing member 110, the smaller the bending force applied to the wire harness 130. Combining Figure 5 shown, Figure 5The positions of the rotating member 120 and the wire harness 130 when the rotating member 120 is in the first position, the second position, and the third position are shown. In one embodiment, the diameter of the wire harness 130 is D. In the direction of the rotation axis, the minimum distance A between the axis of the moving end 132 and the fixing member 110 is A≥5D, so as to reduce the bending degree of the wire harness 130 during the rotation of the rotating member 120 and avoid being too small between the axis of the moving end 132 and the fixing member 110. During the rotation of the rotating member 120, no matter where the rotating member 120 is between the first position and the third position, the position of the axis of the moving end 132 in the direction of the rotation axis remains unchanged, that is, the distance between the axis of the moving end 132 and the fixing member 110 remains unchanged. Therefore, when the axis of the moving end 132 rotates with the rotating member 120 in the rotation plane, the distance between the rotation plane and the fixing member 110 is A. It can be understood that A is the minimum distance between the axis of the moving end 132 and the fixing member 110. It is not the minimum distance between the axis of the moving end 132 and the fixing member 110 during the rotation of the rotating member, but at any rotation angle during the rotation of the rotating member, when analyzing the state where the rotating member 120 is stationary at this rotation angle, the minimum distance between the axis of the moving end 132 and the fixing member 110. In some embodiments, A≤150mm to avoid the distance between the rotation plane and the fixing member 110 being too large, resulting in the wire harness 130 being easily scratched by swinging and making it difficult to control the position of the wire harness 130.
[0049] As shown in combination with Figure 6 shown, Figure 6 The positions of the rotating member 120 and the wire harness 130 when the rotating member 120 is in the first position, the second position, and the third position are shown. In one embodiment, the diameter of the wire harness 130 is D. In the direction perpendicular to the fixing surface 111, during the relative rotation of the rotating member 120 with respect to the fixing member 110, the maximum distance C between the axis of the fixed end 131 and the bent section 133 is such that D≤C≤3D. Among them, C≤3D is used to limit the maximum height of the bent section 133 protruding from the fixing surface 111, so that the wire harness fixing device 100 can be applied to the limitations of narrow spaces. D≤C is used to ensure that there is always a reasonable length of bending amount of the wire harness 130 during the rotation process, avoiding the wire harness 130 being straightened to generate local large stress and making the wire harness 130 easily damaged. During the process of the rotating member 120 rotating from the first position to the third position, as Figure 6 shown, when the rotating member 120 is in the first position, the distance of the bent section 133 protruding from the fixing surface 111 is the highest. At this time, the height difference between the bent section 133 and the axis of the fixed end 131 is the maximum distance C between the axis of the fixed end 131 and the bent section 133.
[0050] It can be understood that when the axis of the fixed end 131 is flush with the axis of the moving end 132, the torsional force on the wire harness 130 is minimized. The greater the difference between the axis of the fixed end 131 and the axis of the moving end 132, the greater the torsional force on the wire harness 130. As Figure 5 shown, the range between the highest point and the lowest point of the bent section 133 during the rotation of the rotating member 120 is the rotation range of the rotating member 120, that is, the rotation range is: as Figure 5 shown, the length B of the swing of the bent section 133 and the polygon area covered by the distance A between the axis of the moving end 132 and the fixed member 110. In one embodiment, in the direction perpendicular to the rotation axis and parallel to the fixed surface 111, the axis of the fixed end 131 is located within the rotation range of the rotating member 120, so that there is at least a second position between the first position and the third position. When the rotating member 120 is in the second position, the axis of the fixed end 131 is flush with the axis of the moving end 132, and at this time, the torsional force on the wire harness 130 is minimized. When the rotating member 120 is between the first position and the second position, the wire harness 130 twists. When the rotating member 120 is between the second position and the third position, the wire harness 130 twists in the reverse direction to avoid excessive torsional force on the wire harness 130 during the rotation of the rotating member 120 caused by too large a difference between the axis of the fixed end 131 and the axis of the moving end 132.
[0051] As Figure 5 shown, in one embodiment, in the direction perpendicular to the rotation axis and parallel to the fixed surface 111, the axis of the fixed end 131 is located at the center of the rotation range of the rotating member 120, so that when the rotating member 120 rotates between the first position and the third position, the torsional force on the wire harness 130 is within a relatively small range.
[0052] As Figure 5 shown, in one embodiment, in the direction perpendicular to the rotation axis and parallel to the fixed surface 111, during the relative rotation of the rotating member 120 with respect to the fixed member 110, the length of the swing of the bent section 133 is B. Among them, in order to balance the torsional force and bending force on the wire harness 130, |B - A| < 1 / 3A and |B - A| < 1 / 3B.
[0053] In one embodiment, B = A to maximize the balance of the torsional force and bending force on the wire harness 130.
[0054] In the wire harness fixing device 100 provided in the above solution, one end of the wire harness 130 is fixed parallel to the rotation axis, and the other end is arranged at an angle with the rotation axis and rotates synchronously with the rotating member 120. When the rotating member 120 rotates, the wire harness 130 bends and twists between the fixed end 131 and the moving end 132. At the same time, by utilizing the flexural strength and torsional strength of the wire harness 130, the wire harness fixing device 100 can be applied to a narrow space, and the requirement for the single performance (flexural strength or torsional strength) of the wire harness 130 is relatively low. For a common wire harness 130, its flexural strength and torsional strength are both within a certain range. If the requirement for the single performance of the wire harness 130 is relatively high, multiple twists or bends will cause the wire harness 130 to break. However, by utilizing the flexural strength and torsional strength of the wire harness 130 simultaneously, the required flexural strength and torsional strength are both lower compared to using the single performance of the wire harness 130, thereby avoiding the wire harness 130 from being twisted or broken, and ensuring the stability and durability of the wire harness 130 during use.
[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0056] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
