Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 to 6 show a preferred embodiment of the present invention.
The routing positioning device 100 is used for positioning a wire connecting a sliding part and a fixed part in a sliding rail structure, and since the distance between a connection point of the sliding part and a connection point on the fixed part changes when the sliding part slides on the fixed part, in order to maximize the distance between the connection points, the wire can still be guided to the sliding part from the fixed part, the length of the wire between the sliding part and the fixed part is at least greater than the maximum distance between the connection points, so that when the distance between the connection points between the sliding part and the fixed part is reduced, the wire between the sliding part and the fixed part is in a bent state.
The routing positioning device 100 in this embodiment includes a flexible strip 110, a first stopper 120, and a positioning portion 130. The flexibility of the flexible belt 110 is represented by that it can be bent and extended, and the bending radius of the flexible belt can be changed with the magnitude of the force, and the flexible belt can be specifically made of materials such as braided belts, elastic rubber, resin and the like. The flexible band 110 is a one-piece structure and is not divided into multiple component parts for assembly.
Two or more first stoppers 120 are arranged on the flexible band 110, each first stopper 120 is uniformly arranged on the first surface of the flexible band 110, and is arranged side by side at intervals along the length direction of the flexible band 110, that is, each first stopper 120 is arranged in a row along the length extending direction of the flexible band 110, and a space is left between each first stopper 120, the above position descriptions all use the flexible band 110 without bending as a reference, when the flexible band 110 is bent, the relative position of each first stopper 120 on the first surface of the flexible band 110 is changed along with the change. The arrangement of two or more first stoppers 120 on a first surface of the flexible band 110 can limit the minimum bending radius of the flexible band 110 when the first surface of the flexible band 110 is bent inward (i.e., after the flexible band 110 is bent, the first surface is located at the inner portion, and a second surface opposite to the first surface is located at the outer portion, and for convenience of description, the bending of the flexible band 110 mentioned below is performed in the above-mentioned direction). After the flexible band 110 is bent to the adjacent two first stoppers 120 at the bending position and the two first stoppers 120 contact and collide, the flexible band 110 cannot be bent continuously, that is, the bending radius of the flexible band 110 is the minimum bending radius when all the two adjacent first stoppers 120 at the bending position contact and collide.
The number of the positioning portions 130 is the same as that of the first limiting blocks 120, the positioning portions 130 are correspondingly arranged on the first limiting blocks 120 one by one, each positioning portion 130 and the first limiting block 120 connected with the positioning portion 130 jointly define a wiring groove 140, when the number of the first limiting blocks 120 is two, the wiring positioning device 100 has two wiring grooves 140, when the number of the first limiting blocks 120 is three, the wiring positioning device 100 has three wiring grooves 140, and so on. The wires are positioned at the flexible band 110 through the respective routing grooves 140 and are bent as the flexible band 110 is bent. One end of the conducting wire is connected with the wiring harness on the sliding part of the sliding rail structure, and the other end of the conducting wire is connected with the wiring harness on the fixing part of the sliding rail structure, so that the purpose of guiding the current at the fixing part to the sliding part is achieved. Since the flexible band 110 has the minimum bending radius and the lead is positioned on the flexible band 110, the lead also has the minimum bending radius when being bent, thereby reducing the influence of fatigue damage on the lead and prolonging the service life of the lead. Moreover, the flexible strip 110 is a whole strip structure, so that the whole routing positioning device 100 is more convenient to manufacture and assemble.
Specifically, for convenience of processing, the first stopper 120 may have a rectangular parallelepiped shape, which may have a solid structure or a hollow structure. The first stopper 120 may be made of one or a combination of plastics, rubber, wood, and resin. When the thickness of the first stopper 120 in the direction perpendicular to the first surface is constant, the distance between two adjacent first stoppers 120 is determined by the set minimum bending radius of the flexible band 110, when the distance between two adjacent first stoppers 120 is larger, the minimum bending radius of the flexible band 110 is smaller, and when the distance between two adjacent first stoppers 120 is smaller, the minimum bending radius of the flexible band 110 is larger. The positioning portion 130 is used to define a wiring groove 140 together with the first stopper 120, and the wiring groove 140 may be located on a surface of the first stopper 120 away from the flexible band 110, or may be located on other surfaces of the first stopper 120. In one embodiment, the positioning portion 130 and the first stopper 120 may be integrally formed, that is, the two components are combined to form an independent integral component, and the wire slot 140 is a through hole for binding a wire.
As shown in fig. 2, the positioning portion 130 may include a positioning plate 131, a U-shaped plate 132, and a connecting bridge 133, the positioning plate 131 extends along a surface of the first stopper 120 facing away from the flexible band 110 toward a direction away from the flexible band 110, the U-shaped plate 132 is parallel to the positioning plate 131, and an open end of the U-shaped plate 132 is connected to the surface of the first stopper 120 facing away from the flexible band 110. The connecting bridge 133 connects the positioning plate 131 and the U-shaped plate 132, and the wire passes through the wiring groove 140 defined between the positioning plate 131, the U-shaped plate 132, the connecting bridge 133 and the first stopper 120 along the direction perpendicular to the connecting bridge 133. The specific structure of the positioning portion 130 can make the positioning portion 130 and the first limiting block 120 easier to be integrally injection-molded, and when the mold is opened, the mold can extend into the wiring groove 140 from the opening of the U-shaped plate 132, so as to facilitate the molding of the wiring groove 140. Specifically, in order to further improve the efficiency and success rate of mold opening during injection molding, the connecting bridge 133 is obliquely arranged, and the distance from one end of the connecting bridge 133 close to the U-shaped plate 132 to the first limiting block 120 is greater than the distance from one end of the connecting bridge 133 close to the positioning plate 131 to the first limiting block 120. Such a structure makes it easier for a mold extending into the wiring groove 140 to be moved out of the wiring groove 140 after the fixing portion and the first stopper 120 are integrally injection molded.
When the flexible band 110 is made of a woven band material, the first stopper 120 may be positioned on the first surface of the flexible band 110 by adhesive bonding, or may be sewn on the flexible band 110. When the flexible band 110 is made of rubber, resin or other flexible materials that can be injection molded, the flexible band 110, the first stopper 120 and the positioning portion 130 can be integrally injection molded. When the first stopper 120 is made of a material harder than the flexible band 110, the routing positioning device 100 can be integrally manufactured by a soft-hard integrated injection molding process.
In one embodiment, the flexible strap 110 is connected at a first end to the sliding portion and at a second end to the fixed portion. The flexible belt 110 is driven to move when the sliding part slides on the fixing part, so that the relative pulling force between the wire between the sliding part and the fixing part and the wire routing positioning device 100 is hardly generated, and the stress of the wire is reduced. When the both ends of flexible band 110 were free state, the both ends of wire will receive the certain size that flexible band 110 gave and pull the power, when the both ends of flexible band 110 were all fixed, the wire can be the lax state completely for the wire is difficult for becoming invalid more.
In another embodiment, the first end of the flexible band 110 is connected to the first hinge 114, the first hinge 114 is hinged to the sliding portion, the second end of the flexible band 110 is connected to the second hinge 115, and the second hinge 115 is hinged to the fixing portion. The hinged connection of the two ends of the flexible band 110 may allow the two ends of the flexible band 110 to be adapted to rotate to increase the distance between the two connection points of the flexible band 110 so that the two connection points do not hinder the sliding of the sliding part when the sliding part needs to be moved beyond its maximum stroke for maintenance or inspection under some special conditions.
When all the first stoppers 120 with the positioning portions 130 are disposed adjacently, after the two first stoppers 120 at the bending portion of the flexible band 110 contact and collide, the positioning portions 130 on the two first stoppers 120 contacting each other may interfere with each other, that is, when the two adjacent first stoppers 120 do not contact yet, the positioning portions 130 on the two stoppers start to generate collision and extrusion. The positioning portion 130 is weak and easily broken when the pressing is generated. Therefore, in order to protect the positioning portion 130, in an embodiment, the routing positioning device 100 further includes a second limiting block 150, and at least one second limiting block 150 is disposed between every two first limiting blocks 120 at intervals, as shown in fig. 4, two second limiting blocks 150 are disposed between every two first limiting blocks 120. The number of the second stoppers 150 between every two first stoppers 120 may be the same or different. The second stopper 150 serves to limit the minimum bending radius of the flexible band 110 when the first surface of the flexible band 110 is bent inward. When the flexible band 110 is bent, the first stopper 120 positioned at the bent portion of the flexible band 110 collides with the second stopper 150, reducing the possibility of position interference between the two positioning portions 130 closest to each other. Specifically, the material, shape and size of the second stopper 150 may be completely the same as those of the first stopper 120, so that the second stopper 150 is easy to manufacture, and when the material, shape and size of the second stopper 150 is completely the same as those of the first stopper 120, the difference between the two is whether the positioning portion 130 is arranged thereon.
When the flexible band 110 is bent, a portion of the flexible band 110 near the first surface is pressed and a portion near the second surface is stretched in the thickness direction thereof. To prevent the material on the flexible strap 110 from being over-stretched or over-compressed, in one embodiment, the first surface is formed with a first buffer groove 111, and the first buffer groove 111 is located in the gap between the first stopper 120 and the second stopper 150. Further, a second surface of the flexible band 110 opposite to the first surface is formed with a second buffer groove 112, and the second buffer groove 112 is disposed opposite to the first buffer groove 111. Specifically, in order to reduce the resistance applied when the flexible band 110 is bent, a first buffer groove 111 may be formed in a gap between each of the first stopper 120 and the second stopper 150, a plurality of second buffer grooves 112 may be formed on the second surface, and each of the second buffer grooves 112 and each of the first buffer grooves 111 are uniformly and oppositely arranged. Because there is a large distance between the two second buffer grooves 112, in order to save material and further prevent the material of the flexible band 110 near the second surface from being excessively stretched, a third buffer groove 113 may be formed between every two second buffer grooves 112, and the third buffer groove 113 is formed at a position of the second surface opposite to the first stopper 120 or the second stopper 150, and may be specifically disposed in the middle of the two second buffer grooves 112. The first buffer groove 111, the second buffer groove 112, and the third buffer groove 113 may extend out of both sides of the flexible band 110 in the width direction of the flexible band 110.
The second aspect of the present invention further provides a refrigerator, which includes the routing positioning device 100 for a sliding rail structure in any of the above embodiments.
Particularly, the refrigerator has a drawer cabinet 200, the drawer cabinet 200 is integrally disposed with a door body of the refrigerator and forms a drawable storage space, the drawer cabinet 200 and a refrigerator body form a sliding rail structure, the drawer cabinet 200 can be regarded as a sliding portion, and the refrigerator body can be regarded as a fixing portion. The drawer cabinet 200 is provided with components requiring continuous power supply, for example, in some embodiments, a display screen, various lighting elements, and the like are required to be arranged on an outer panel of the drawer cabinet 200, and these components need to be continuously operated during the drawing process of the drawer, and at this time, a current on the refrigerator body needs to be led to the drawer cabinet 200 by using a wire.
As shown in fig. 5 to 6, a junction box 210 may be disposed on a vertical side surface of the drawer cabinet 200 parallel to the sliding direction thereof, such that one end of the flexible strap 110 is hinged to the junction box 210, and the other end is hinged to a certain portion of the refrigerator body, and a lead wire led out from the refrigerator body passes through each wire slot 140 on the wire positioning device 100, extends into the junction box 210 of the drawer cabinet 200, and is connected to a wire harness connector in the junction box 210, so as to guide the current to the drawer cabinet 200.
