Description
Technical Field
[0001] This utility model belongs to the technical field of glass lifters, specifically relating to a bracket with a limiting structure. Background Technology
[0002] With the continuous emergence of new materials and advanced technologies, people's traditional understanding and definition of car windows are undergoing profound changes. Car windows are gradually transforming from simple material components into a core carrier in the trend of automotive intelligence. Today, car windows have many functions such as facial recognition, intelligent voice, eye tracking, AR / VR, dimming, heating, and video, which can meet the different needs of drivers and passengers and greatly enhance the diversity and practicality of in-vehicle entertainment systems.
[0003] For example, the BMW iVisionDee projects a virtual image of the driver onto the side window, pioneering a new mode of human-vehicle interaction. However, to achieve these functions on the window glass, it is necessary to rely on related electrical components and a power supply. Therefore, a wiring harness is required to connect the power supply interface at the door wiring harness end and the power receiving interface at the glass end, and the wiring harness needs to be able to move with the raising and lowering of the window glass.
[0004] In 2023, our company filed a Chinese utility model patent, authorized publication number CN221162130U, entitled "A Functional Window Regulator Bracket." The bracket is equipped with a snap-fit connector, through which the wiring harness is installed to the bracket to allow the wiring harness to move with the raising and lowering of the vehicle window. However, during use, it was found that due to vehicle vibration and temperature differences, the wiring harness is prone to detaching from the snap-fit connector after long-term use, causing the wiring harness to slap against the bracket and produce abnormal noise. Utility Model Content
[0005] The purpose of this utility model is to provide a bracket with a limiting structure, which prevents the wire harness from falling off the bracket due to environmental influences.
[0006] The purpose of this utility model is achieved through the following technical solution: it includes a bracket body and a wire harness support frame disposed on one side of the bracket body. The wire harness support frame is provided with an installation groove with a slot and a limiting structure, and the limiting structure is disposed on the outside of the slot.
[0007] Preferably, the limiting structure is an arc-shaped limiting baffle, which is integrally formed with the wire harness support frame.
[0008] Preferably, the limiting baffle is provided with guide ribs.
[0009] Preferably, the mounting groove has a limiting protrusion near the groove opening.
[0010] Preferably, the limiting structure consists of a limiting hole and a limiting member, with the limiting member snapped into the limiting hole.
[0011] Preferably, it also includes a guide assembly, which is mounted on one side of the bracket body.
[0012] Preferably, the guide component includes a plurality of elastic slots, which are spaced apart along one side of the bracket body, and the elastic slots have slot openings facing away from the bracket body.
[0013] Preferably, the guide assembly further includes several limiting support frames, each with a limiting baffle that is opposite to the slot opening.
[0014] Preferably, the guide assembly further includes a load-bearing slot with its opening facing the bracket body.
[0015] Due to the adoption of the above technical solution, this utility model has the following advantages:
[0016] The wiring harness is mounted on the wiring harness support frame and its movement is restricted by the positioning structure. During vehicle use, the wiring harness can avoid falling off the support body due to environmental factors such as vibration or temperature, and avoid collisions between the wiring harness and the support body or components on the door panel that could cause abnormal noises.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0031] Please see Figures 1 to 4 A bracket with a limiting structure includes a bracket body 1 and a wire harness support frame 2 disposed on one side of the bracket body 1. The wire harness support frame 2 has a mounting groove 21 with a notch 211 and a limiting structure, the limiting structure being disposed on the outside of the notch 211. Specifically, the bracket body 1 is injection molded, and the upper part of the bracket body 1 has an opening mounting groove 11 for mounting functional glass or glass clips. The bracket body 1 is mounted on a guide rail and moves along the guide rail. The guide rail is mounted on a door base plate 5, and the wire harness 4 is connected to the functional glass. The wire harness support frame 2 is integrally formed with the bracket body 1 to increase the strength of the wire harness support frame 2, or the wire harness support frame 2 is fixed to the side of the wire harness support frame 2 facing the direction of wire harness insertion into the bracket body 1 by screws, or is installed on the bracket body 1 by snap-fit method as specified in authorization announcement number CN221162130U, to facilitate replacement of damaged bracket body 1 or wire harness support frame 2. The mounting slot 21 is symmetrically provided with mounting edges 212. The wire harness 4 is provided with an adapter 41. The adapter 41 is provided with a groove 411 that cooperates with the mounting edge 212. Preferably, the groove 411 is located in the middle of the adapter 41 and extends along the length of the adapter 41. The distance between the relative inner walls of the groove 411 is slightly greater than the thickness of the mounting edge 212.
[0032] This utility model discloses a bracket with a limiting structure. During installation, the adapter 41 is first installed in the mounting groove 21 with the groove 411 and the mounting edge 212, thereby limiting the vertical movement of the adapter 41. The distance between the inner walls of the groove 411 is slightly larger than the thickness of the mounting edge 212. When the wire harness 4 is subjected to external force, it can provide a small space for the adapter 41 to move vertically, avoiding the adapter 41 from being rigidly stressed and the wire harness 4 from being damaged. Then, the limiting structure restricts the horizontal movement of the adapter 41, thereby restricting the movement of the adapter 41 in the X, Y, and Z directions. The wire harness 4 is installed on the wire harness support frame 2. During vehicle use, the wire harness 4 can avoid being affected by vibration or temperature and other environmental factors, thus preventing it from falling off the bracket body 1 and avoiding collisions between the wire harness 4 and components on the bracket or door base plate 5, which could cause abnormal noise.
[0033] Example 1
[0034] Further, please refer to Figure 3 The limiting structure is an arc-shaped limiting baffle (22), which is integrally formed with the wire harness support frame (2). Specifically, the wire harness support frame 2 is symmetrically provided with arc-shaped limiting baffles 22, and the distance between the inner walls of the limiting baffles 22 near the slot 211 is less than the distance between the inner walls of the mounting slot 21. The cross-section formed by the two sets of limiting baffles 22 is trumpet-shaped, with the inner wall size decreasing from the outside to the inside, and the large outer size facilitating the entry of the adapter 41 into the space formed by the limiting baffles 22. Both limiting baffles 22 are elastic, in which case the adapter 41 of this application can be deformed or not deformed; or one limiting baffle 22 is elastic, and the other is replaced by a fixing rib, in which case the adapter 41 of this application is deformed. The adapter 41 is inserted, and the deformation of the limiting baffle 22 creates space for the adapter 41 to smoothly enter the mounting groove 21, or the adapter 41 deforms smoothly into the mounting groove 21, facilitating the assembly of the adapter 41. After the adapter 41 enters the mounting groove 21, it disengages from the limiting baffle 22, and the limiting baffle 22 returns to its original shape. Because the distance between the inner walls of the limiting baffle 22 near the groove opening 211 is less than the distance between the inner walls of the mounting groove 21, the limiting baffle 22 restricts the adapter 41 from moving outward, preventing the adapter 41 from falling off after assembly, thus achieving quick assembly and fixation of the adapter 41. Preferably, the inner end face of the limiting baffle 22 is flat, resulting in a large contact area when the adapter 41 contacts the inner end of the limiting baffle 22.
[0035] Further, please refer to Figure 3 A gap is provided between the limiting baffle 22 and one side of the slot 211. This gap provides space for the adapter 41 to move horizontally when subjected to external force, effectively buffering the force on the adapter 41 and preventing damage to the wiring harness 4 due to rigid stress on the adapter 41; it also provides deformation space for the limiting baffle 22 under stress, preventing it from getting stuck and unable to recover its deformation, thus enabling quick assembly and fixation of the adapter 41. Preferably, the gap is 0.3mm to 0.5mm.
[0036] Further, please refer to Figure 1 The limiting baffle 22 is provided with a guide rib 221. Specifically, the thickness of the guide rib 221 is less than the distance between the inner walls of the groove 411. When the adapter 41 is installed in the two limiting baffles 22, the guide rib 221 supports the adapter 41 to slide along the limiting baffle 22 to the mounting edge 212, so as to realize the quick assembly and fixation of the adapter 41.
[0037] Further, please refer to Figure 3 and Figure 4 The mounting groove 21 is symmetrically provided with limiting protrusions 213 near the groove opening 211. Specifically, the adapter 41 is provided with a groove 412 that mates with the limiting protrusion 213. The groove 412 communicates with the groove 411. The limiting protrusion 213 is folded inward along the inner wall of the mounting groove 21. The distance between the two limiting protrusions 213 is less than the distance between the inner walls of the mounting groove 21. After the adapter 41 is inserted into the mounting groove 21, the limiting protrusion 213 is in the groove 412, thereby further assisting the limiting baffle 22 and preventing the adapter 41 from falling off after assembly. Preferably, the end of the limiting protrusion 213 facing the insertion direction of the adapter 41 is an arc surface, which facilitates the adapter 41 to enter the mounting groove 21. The end away from the insertion direction of the adapter 41 is a flat surface, so that the contact area is large when the adapter 41 contacts the limiting protrusion 213.
[0038] Example 2
[0039] Further, please refer to Figure 6 and Figure 7 The limiting structure consists of a limiting hole 214 and a limiting element, with the limiting element installed in the limiting hole 214. Specifically, a limiting hole 214 is provided on the front surface of the mounting edge 212; the limiting element is used to prevent the adapter 41 from falling off. The limiting element includes, but is not limited to, screws, bolts and nuts, and snap-fit pins 23. If a screw is used, the limiting hole 214 is a threaded hole, and the screw is installed in the limiting hole 214 by threaded connection. If a snap-fit pin 23 is used, its insertion end is provided with an anti-disengagement hook 231, and a relief groove 232 is provided along the axial direction of the snap-fit pin 23. The relief groove 232 is vertically set, and the snap-fit pin 23 is snap-fitted into the limiting hole 214.
[0040] Furthermore, the bracket also includes a guide assembly 3, which is mounted on one side of the bracket body 1. Specifically, after the wiring harness 4 is assembled into the mounting groove 21, it is positioned around the guide assembly 3 to constrain the direction of the wiring harness 4. The guide assembly 3 is located on the side of the bracket body 1 away from the functional glass. The guide assembly 3 can be integrally formed with the bracket body 1 or installed on the bracket body 1 by screws. In use, the wiring harness 4 is mounted on the guide assembly 3, which not only prevents the wiring harness 4 from detaching and colliding with components on the door base plate 5 when the bracket body 1 slides, but also allows the wiring harness 4 to extend out of the bracket body 1 along the layout of the guide assembly 3, resulting in a smoother connection with the functional glass.
[0041] Further, please refer to Figure 1 and Figure 5 The guide component 3 includes several elastic slots 31, with the slot openings 311 of the elastic slots 31 facing away from the bracket body 1. The elastic slots 31 are spaced apart along one side of the bracket body 1. Specifically, the elastic slots 31 are located on the side of the bracket body 1 away from the functional glass, and their cross-sections are U-shaped, C-shaped, or rectangular. The distance between the inner walls of the elastic slots 31 and the wire harness 4 is slightly smaller than the diameter of the wire harness 4. The wire harness 4 is constrained by the deformation of the elastic slots 31 to clamp it.
[0042] Further, please refer to Figure 1 and Figure 5 The guide assembly 3 also includes several limiting support frames 32, each with a limiting baffle 321. The limiting baffle 321 is opposite to the slot opening 311. Specifically, the limiting support frame is L-shaped, and the height of the limiting baffle 321 is at least greater than the radius of the wire harness 4. The baffle 321 is opposite to the slot opening 311, effectively preventing the wire harness 4 from falling out of the elastic slot 31, and further contributing to the stable assembly of the wire harness 4.
[0043] Further, please refer to Figure 1 and Figure 5 The guide assembly 3 also includes a load-bearing slot 33, the opening of which faces the bracket body 1. Specifically, the wire harness 4 is provided with a wire harness connector 42, and the load-bearing slot 33 is elastic and located near the wire harness connector 42. This structure effectively prevents the wire harness 4 from falling off the bracket body 1 due to the gravity of the wire harness connector 42.
[0044] This utility model discloses a bracket with a limiting structure. A wiring harness 4 is installed in a mounting groove 21. A limiting structure is provided on the outside of the mounting groove 21 to prevent the adapter 41 from detaching from the bracket body 1 due to vibration or temperature changes after assembly. It also prevents the wiring harness 4 from colliding with components on the bracket or door panel, thus avoiding abnormal noise. The wiring harness 4 extends out of the bracket body 1 along the guide assembly 3. During vehicle use, the wiring harness 4 avoids collisions with components on the door panel, reducing damage and ensuring smooth connection to the functional glass.
