Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of spare part positioning, and particularly relates to a positioning structure capable of preventing parts from moving and an automobile. BACKGROUND

[0002] In existing mechanical devices, the fixation between parts usually relies on fasteners such as bolts and screws. Although these methods are widely used in various mechanical equipment, they have exposed some significant problems in practical application:

[0003] 1. Due to external vibration (such as vibration during machine operation or impact during transportation) or material fatigue caused by long-term use, the fasteners may gradually loosen. This loosening not only may cause the position of the parts to deviate, but also may cause noise, increased wear and tear, and even functional failure of critical components, seriously affecting the overall performance and safety of the equipment.

[0004] 2. The installation of traditional fasteners usually requires the use of specific tools (such as wrenches and screwdrivers), and the operating personnel need to have certain skill levels to ensure the correct tightening torque. This not only increases the time cost of assembly, but also increases the risk of incorrect installation, thereby affecting product quality.

[0005] 3. Once the fasteners loosen or have other problems, professional maintenance personnel are often needed to re-tighten or replace them. For some difficult-to-access locations, this will greatly increase the difficulty and cost of maintenance.

[0006] Therefore, the existing fixation method not only cannot guarantee the stability of the connection between parts, but also increases the overall assembly difficulty and time cost, and cannot meet the use requirements of assembly. SUMMARY

[0036] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

[0038] As Figure 1 shown, in the present solution, a positioning structure for preventing parts from moving is mainly described for use in a car, but the positioning structure for preventing parts from moving is not limited to being used in a car, and can also be applied to other parts that need to be assembled.

[0039] Embodiment one:

[0040] As Figure 1 and Figure 4As shown, a positioning structure capable of preventing parts from shifting, comprising: a decorative plate 1, on which a protruding part 10 is arranged; a base 2 mounted on the decorative plate 1, the base 2 having a positioning surface 20 and a first body part 21 and a second body part 22 with a height difference, a top wall of the positioning surface 20 being formed with a locking groove 200a; the first body part 21 and the second body part 22 are both formed with an extension plate 230; an anti-disengagement piece 3 and a positioning piece 4, the top wall of the protruding part 10 is provided with at least one anti-disengagement piece 3, and at least one set of anti-disengagement pieces 3 and positioning pieces 4 are distributed on both sides of the protruding part 10; the positioning piece 4 is formed with a first positioning plate 40 and a second positioning plate 41 connected with each other; the first positioning plate 40 and the second positioning plate 41 can penetrate through the base 2 to limit the horizontal movement of the base 2 relative to the decorative plate 1, so that the positioning surface 20 can be movably attached to the protruding part 10, so that the anti-disengagement piece 3 on one side of the protruding part 10 can be movably clamped on the extension plate 230, and the anti-disengagement piece 3 on the top wall of the protruding part 10 can be extruded and deformed when sliding through the locking groove 200a, and can be elastically reset and clamped on the top wall of the positioning surface 20 when crossing the locking groove 200a, thereby limiting the vertical movement of the base 2 relative to the decorative plate 1.

[0041] After the base 2 and the decorative plate 1 in the embodiment are installed, the required assembly requirements for the buttons on the car can be provided, specifically, Figures 1 to 4As shown, the design of the protrusion 10 in this embodiment provides a precise installation reference point, enabling the base 2 to be accurately placed in the required position on the decorative panel 1. During the placement of the base 2 on the decorative panel 1, the first positioning plate 40 and the second positioning plate 41 on the positioning member 4 penetrate the base 2, restricting its horizontal movement relative to the decorative panel 1. This allows the base 2 to achieve a self-guiding and self-locking effect during installation, ensuring that the base 2 is initially fixed in the correct position, thus guaranteeing accuracy during assembly. Simultaneously, the positioning surface 20 of the base 2 is also close to the side wall of the protrusion 10, facilitating subsequent tightening operations, reducing additional tightening steps and tool usage, and simplifying the installation process. It is worth noting that in this embodiment... One or more sets of anti-detachment components 3 are distributed on both sides of the central protrusion 10. These anti-detachment components 3 can be movably engaged with the corresponding extension plate 230 during the descent of the base 2. In addition, this embodiment also provides at least one anti-detachment component 3 on the top wall of the protrusion 10. When these anti-detachment components 3 slide through the locking groove 200a, they will deform due to compression. As the base 2 continues to be pressed down, the anti-detachment component 3 will return to its original shape due to its elasticity after crossing the locking groove 200a and be firmly engaged with the top wall of the positioning surface 20. This effectively prevents the base 2 from moving in the vertical direction and further strengthens the connection between the base 2 and the decorative panel 1. After completing the above steps, the base 2 is stably fixed to the decorative panel 1, forming a strong and reliable connection. Even under vibration or impact conditions, this structure can maintain good stability, avoiding the loosening or displacement problems that may occur in traditional structures, and enhancing the stability and reliability of the overall assembly.

[0042] The first positioning plate 40 and the second positioning plate 41 both include a guide surface 420 and a locking surface 421. The guide surface 420 is inclinedly disposed at the ends of the first positioning plate 40 and the second positioning plate 41 to guide the base 2 into the positioning member 4. The locking surface 421 is disposed at an angle to the guide surface 420 to limit the displacement of the base 2 relative to the decorative panel 1.

[0043] like Figures 1 to 4 As shown, during installation, the base 2 is gradually guided to the correct position by the inclined guide surfaces 420 on the first positioning plate 40 and the second positioning plate 41. The design of the guide surfaces 420 allows the base 2 to slide smoothly into the positioning component 4 even with slight angular or positional deviations during assembly, simplifying the assembly process and allowing for faster and more accurate positioning of the base 2, reducing the need for precise alignment. Once the base 2 is fully inside the positioning component 4, the locking surface 421 restricts the base 2's movement on the trim panel 1, reducing the risk of malfunctions caused by component displacement. This also ensures the accuracy and stability of the anti-detachment component 3 when further securing the base 2.

[0044] The first positioning plate 40 and the second positioning plate 41 are arranged in a cross shape, and the two side walls of the first body part 21 and the second body part 22 are each formed with a positioning hole 231, and the first positioning plate 40 and the second positioning plate 41 are movably penetrated through the positioning hole 231.

[0045] Preferably, as shown in Figure 1 and Figure 4 the embodiment one, the positioning plate can provide support from multiple directions through the cross-shaped layout, increasing the overall rigidity and stability of the positioning member 4 while also improving the load-bearing capacity of the connection points. Furthermore, the cross-shaped arrangement combined with the movably penetrated design greatly simplifies the assembly steps, reduces the need for precise alignment, making installation more convenient and fast, suitable for mass production and assembly requirements.

[0046] The first positioning plate 40 is further formed with a locking inclined surface 400 arranged in a flared shape, and the large end opening of the locking inclined surface 400 is connected to the decorative plate 1; the positioning member 4 further includes an abutting surface 422 formed on the second positioning plate 41, which is used to movably abut against the bottom wall of the base 2.

[0047] Further preferably, as shown in Figure 4 the locking inclined surface 400 is symmetrically distributed on both sides of the first positioning plate 40 and arranged in a flared shape, and during the penetration of the first positioning plate 40 and the second positioning plate 41 through the positioning hole 231, the locking inclined surface 400 can work together with the guiding surface 420 to guide the installation of the base 2, while the gradually shrinking design of the flared locking inclined surface 400 provides a gradually increasing locking force, which cooperates with the locking effect of the abutting surface 422 on the base 2 in the vertical direction, making the entire structure more stable and reliable, thereby improving the overall quality of the product and the satisfaction of the user.

[0048] The anti-disengagement member 3 includes a support block 30 arranged in the vertical direction, an anti-disengagement block 31 connected to the top end of the support block 30, and a top end of the positioning surface 20 is further formed with a flange 200, a locking groove 200a is arranged on the flange 200, the anti-disengagement block 31 can be extruded and deformed when the locking groove 200a slides through, and elastically returns after the locking groove 200a passes, so that the anti-disengagement block 31 is movably pressed against the top wall of the flange 200; a reinforcing rib 32 is installed on the side wall of the support block 30, and the top end of the reinforcing rib 32 has a height difference with the bottom wall of the anti-disengagement block 31.

[0049] As shown in Figure 3As shown, after the base 2 is positioned by the aforementioned positioning member 4, the positioning surface 20 adheres tightly to the side wall of the protrusion 10. Simultaneously, the flange 200 moves towards the anti-detachment member 3 as the base 2 advances. During this process, the anti-detachment block 31 first contacts the locking groove 200a on the flange 200. Due to the elasticity of the anti-detachment block 31, it will be squeezed and deformed when it encounters the locking groove 200a, thus allowing the base 2 to continue moving forward. Once the anti-detachment block 31 has completely passed through the locking groove 200a, it will quickly return to its original position due to its own elasticity, pressing tightly against the top wall of the flange 200, restricting the vertical movement of the base 2, and ensuring the stability of the overall assembly. In this structure, the elastic deformation capability of the anti-detachment block 31 allows the structure to be finely adjusted under different environmental conditions, avoiding stress accumulation caused by material expansion or contraction; while the presence of the reinforcing rib 32 significantly enhances the structural strength of the support block 30, enabling the anti-detachment member 3 to withstand greater external forces without easily being damaged, thus extending its service life.

[0050] A mounting block 100 is also formed on the protrusion 10. The support block 30 and the reinforcing rib 32 are both provided on the mounting block 100, and an open cavity 100a is formed between the mounting block 100 and the protrusion 10.

[0051] More preferably, such as Figure 4 As shown, the design of the mounting block 100 in this embodiment can ensure that the support block 30 and the anti-detachment block 31 are in the required position to achieve stable pressing of the base 2. On the other hand, the open cavity 100a reduces the contact area between the anti-detachment part 3 and the protrusion 10. At the same time, the thin-walled design at the root of the mounting block 100 effectively prevents shrinkage during processing.

[0052] Example 2:

[0053] The second positioning plate 41 includes a first positioning part 410 and a second positioning part 411. The first positioning part 410 and the second positioning part 411 are staggered and distributed on both sides of the first positioning plate 40. A positioning groove 232 is formed at the bottom of the base 2. The first positioning plate 40, the first positioning part 410 and the second positioning part 411 pass through the positioning groove 232.

[0054] This second embodiment is based on the first embodiment with corresponding adjustments. While other structures remain the same, the structure of the second positioning plate 41 can be improved in this second embodiment as follows: [Example of improvements would be inserted here]. Figure 3As shown, unlike the first positioning plate 40 and the second positioning plate 41 with a cross-shaped design in Embodiment 1, the first positioning part 410 and the second positioning part 411 on the second positioning plate 41 are staggered, providing multiple independent locking points, which significantly enhances the rigidity and torsional resistance of the structure, making the whole system more stable and reliable, greatly improving the fault tolerance and flexibility of assembly, and even novices can complete the assembly quickly and accurately.

[0055] Preferably, in this embodiment, a movement gap 421a is formed between the locking surface 421 and the base 2 (i.e., the inner wall of the positioning hole 231 or the positioning groove 232). The parts can be positioned using any of the positioning methods in Embodiment 1 and Embodiment 2. The movement gap 421a of 0.1mm on one side provides sufficient tolerance for assembly. Even if there are slight dimensional deviations during the production process, it will not affect the final assembly quality.

[0056] More preferably, such as Figure 3 As shown, in this second embodiment, the first positioning part 410 or the second positioning part 411 located on the same side are symmetrically arranged on the first positioning plate 40. It should be noted that the first positioning part 410 and the second positioning part 411 can be adjusted in position during the manufacturing process according to the overall length of the first positioning plate 40. This helps to ensure that the movement of the parts is evenly distributed to adapt to the positioning of the square groove or round hole, and avoids the parts from failing to meet the required assembly requirements due to excessive movement at a certain position.
