A non-deformation space through jig mounting structure

Abstract

This application belongs to the field of cleaning robot technology, specifically relating to a non-deformable space installation structure using a jig. It includes a base shell and a collision drop bracket. The base shell has a movable groove for the collision drop bracket to connect and mate with. The movable groove allows the collision drop bracket to extend upwards in a first orientation and restricts its downward disengagement in a second orientation. This application achieves pressure-free assembly by designing the movable groove to only allow the collision drop bracket to extend upwards in the first orientation and restrict its downward disengagement in the second orientation. This fundamentally avoids the problem of plastic deformation caused by external force during installation, ensuring the buckle height and structural integrity. Simultaneously, this directional assembly method and the precise constraint of the movable groove allow the bracket to maintain a preset minimum movement gap within the groove for smooth forward and backward sliding, while effectively suppressing wobbling caused by excessive gaps.

Description

[Technical Field]

[0002] This application belongs to the field of cleaning robot technology, specifically relating to a non-deformable space mounting structure using a fixture. [Background Technology]

[0004] In existing cleaning robots, when the impact drop bracket is installed into the movable slot of the base shell, if a non-elastic wall design is used and external force is forcibly applied without auxiliary tooling, irreversible plastic deformation of the latching structure on the impact drop bracket can easily occur. This reduces the latching height, preventing the bracket from sliding smoothly back and forth within the predetermined movable slot space. However, simply increasing the height of the latching space in the movable slot to try to avoid deformation will increase the swaying gap of the impact drop bracket within the slot, thereby interfering with and affecting the normal operation of the associated light-blocking coupler structure. Therefore, there is an urgent need for an installation method that can both prevent the latching from deforming under strong pressure during installation and ensure that the bracket maintains an appropriate gap within the movable slot, thus maintaining structural stability. [Utility Model Content]

[0006] To address the issues of plastic deformation and structural swaying during the installation of impact drop brackets in existing technologies, this application provides a deformation-free space installation structure using a fixture.

[0007] This application is achieved through the following technical solution:

[0008] A non-deformable space mounting structure via a fixture includes a base shell and a collision drop bracket. The base shell is provided with a movable groove for the collision drop bracket to connect and cooperate with. The movable groove allows the collision drop bracket to extend upward in a first position and restricts the collision drop bracket from disengaging downward in a second position.

[0009] As described above, in a non-deformable space installation structure using a fixture, the collision drop bracket is provided with symmetrically arranged limit buckles, and the edge of the movable groove is provided with a limit platform for the limit buckles to abut and cooperate.

[0010] As described above, in a non-deformable space fixture mounting structure, the collision drop bracket includes a support portion and a snap-fit ​​portion, and the snap-fit ​​portion is provided with a connecting groove for the fixture to be inserted and fitted.

[0011] As described above, in a non-deformable space mounting structure using a fixture, the limiting buckle is disposed on the snap-fit ​​part, the outer edge spacing of the two limiting buckles is L, the width of the snap-fit ​​part is B, the length of the movable groove is S, and the width of the movable groove is D, wherein S≥L>D.

[0012] In the above-described non-deformable space mounting structure using a fixture, the length of the snap-fit ​​portion is C, where D > C.

[0013] As described above, a non-deformable space is installed via a fixture structure, wherein the limiting platform is provided with a limiting wall that abuts against the limiting buckle, and the limiting buckle abuts against the limiting wall to restrict the collision drop bracket from rotating relative to the movable groove.

[0014] As described above, a non-deformable space mounting structure via a fixture includes a steering column and three guide positioning columns disposed on the steering column and spaced at right angles around the steering column. The shape of the connecting groove is adapted to the steering column and the guide positioning columns.

[0015] As described above, in a non-deformable space fixture installation structure, the snap-fit ​​part has a first arc edge on one side corresponding to the three guide positioning posts, and the movable groove has a second arc edge corresponding to the first arc edge.

[0016] Compared with the prior art, this application has the following advantages:

[0017] This application discloses a non-deformable space fixture installation structure. By designing the movable groove to allow the impact drop bracket to extend upward in a first position and restrict its downward disengagement in a second position, it achieves pressure-free assembly. This fundamentally avoids the problem of plastic deformation caused by external force during installation, ensuring the bracket height and structural integrity. At the same time, this directional assembly method and the precise constraint of the movable groove allow the bracket to maintain a preset minimum movement gap within the groove for smooth forward and backward sliding, while effectively suppressing wobbling caused by excessive gap.

Detailed Implementation Methods

[0028] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0029] Please see Figures 1 to 7 A non-deformable space mounting structure via a fixture includes a base shell 1 and a collision drop bracket 2. The base shell 1 is provided with a movable groove 11 for connecting and cooperating with the collision drop bracket 2. The movable groove 11 allows the collision drop bracket 2 to extend upward in a first orientation 2a and restricts the collision drop bracket 2 from disengaging downward in a second orientation 2b.

[0030] This application discloses a non-deformable space fixture installation structure. By designing the movable groove to allow the impact drop bracket to extend upward in a first position and restrict its downward disengagement in a second position, it achieves pressure-free assembly. This fundamentally avoids the problem of plastic deformation caused by external force during installation, ensuring the bracket height and structural integrity. At the same time, this directional assembly method and the precise constraint of the movable groove allow the bracket to maintain a preset minimum movement gap within the groove for smooth forward and backward sliding, while effectively suppressing wobbling caused by excessive gap.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the collision drop bracket 2 is provided with symmetrically arranged limit buckles 21, and the edge of the movable groove 11 is provided with a limit platform 111 for the limit buckles 21 to abut and cooperate.

[0032] In this embodiment, during installation, after the collision drop bracket is inserted into the movable slot at the first azimuth angle, the limiting buckle can be misaligned with the limiting platform. Then, the collision drop bracket is rotated to the second azimuth position. At this time, the limiting buckle 21 naturally engages below the limiting platform 111, which not only restricts the vertical displacement of the bracket but also retains the reasonable gap required for horizontal sliding, thereby ensuring structural stability without affecting the normal sliding function of the bracket.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the collision drop bracket 2 includes a support portion 22 and a snap-fit ​​portion 23, wherein the snap-fit ​​portion 23 is provided with a connecting groove 231 for the fixture 3 to be inserted and fitted.

[0034] In this embodiment, the rotational force and positioning guide force are transmitted through the fixture, fundamentally eliminating the risk of plastic deformation caused by traditional forced pressing. During installation, the fixture 3 engages with the connecting groove 231 on the snap-fit ​​part 23, allowing the mechanical force of the fixture 3 to accurately install the impact drop bracket 2 into the movable groove 11 of the base shell, avoiding the problem of buckle deformation caused by directly applying external force to the impact drop bracket. Its beneficial effect is that the cooperation between the fixture 3 and the connecting groove 231 allows for precise control of the installation position and force of the impact drop bracket 2, ensuring the correct engagement of the limit buckle 21 and the limit platform 111, while avoiding installation errors and structural damage caused by improper human operation, thus improving installation efficiency and reliability.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the limiting buckle 21 is disposed on the snap-fit ​​portion 23, the outer edge spacing of the two limiting buckles 21 is L, the width of the snap-fit ​​portion 23 is B, the length of the movable groove 11 is S, and the width of the movable groove 11 is D, wherein S≥L>D.

[0036] In this embodiment, the setting of S≥L ensures that the bracket can smoothly enter the movable slot, while the key restriction of L>D creates a clever anti-detachment structure, so that after the bracket is installed in place, the limiting buckle 21 can naturally lock into the inner side of the movable slot 11 to form a reliable mechanical lock, which not only prevents the bracket from falling off accidentally, but also avoids damage to the buckle by the traditional pressing method. Its working principle is that the bracket is inserted into the movable slot 11 at a specific angle during installation. When rotated to the working position, due to the size design of L>D, the limiting buckle 21 will automatically lock into the limiting platform to form a stable support structure, which not only ensures the accurate positioning of the bracket, but also ensures that the bracket has an appropriate movement gap in the slot through the size tolerance distribution to achieve smooth sliding.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the length of the snap-fit ​​portion 23 is C, where D > C.

[0038] In this embodiment, the collision drop bracket 2 is ensured to rotate to the second position after being inserted into the movable slot to prevent the collision drop bracket 2 from detaching from the housing 1. This ensures that the collision drop bracket 2 can be installed smoothly and that it is stable and reliable within the movable slot 11.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the limiting platform 111 is provided with a limiting wall 1111 that abuts against the limiting buckle 21. The limiting buckle 21 abuts against the limiting wall 1111 to restrict the collision drop bracket 2 from rotating relative to the movable groove 11.

[0040] In this embodiment, after the bracket is installed in place, the limiting buckle 21 and the limiting wall 1111 form a rigid stop in surface contact, which completely restricts the rotational degree of freedom of the bracket, while the linear sliding degree of freedom of the bracket is retained through the cooperation of the movable groove 11 and the snap-fit ​​part 23. This selective degree of freedom restriction method not only ensures the normal movement function of the bracket, but also ensures that it always maintains the correct orientation during the operation.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the fixture 3 includes a steering column 31 and three guide positioning posts 311 disposed on the steering column 31 and spaced at right angles around the steering column 31, and the shape of the connecting groove 231 is adapted to the steering column 31 and the guide positioning posts 311.

[0042] In this embodiment, when installing the collision drop bracket 2, the steering shaft 31 and guide positioning pin 311 of the fixture 3 can precisely engage with the connecting groove 231 of the collision drop bracket 2. Through the three guide positioning pins 311 arranged at right angles, the fixture 3 can drive the collision drop bracket to rotate, ensuring that the collision drop bracket 2 can be accurately aligned with the movable groove 11 during installation and remain stable during installation, avoiding positional displacement caused by external forces.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, the snap-fit ​​part 23 is provided with a first arc edge 232 on one side corresponding to the three guide positioning posts 311, and the movable groove 11 is provided with a second arc edge 112 corresponding to the first arc edge 232.

[0044] In this embodiment, the streamlined edge design not only eliminates stress concentration caused by sharp corners, but also compensates for assembly deviations caused by manufacturing tolerances through the automatic centering characteristics of the arc surface contact.

[0045] The working principle of this embodiment is as follows:

[0046] This application discloses a non-deformable space fixture installation structure. By designing the movable groove to allow the impact drop bracket to extend upward in a first position and restrict its downward disengagement in a second position, it achieves pressure-free assembly. This fundamentally avoids the problem of plastic deformation caused by external force during installation, ensuring the bracket height and structural integrity. At the same time, this directional assembly method and the precise constraint of the movable groove allow the bracket to maintain a preset minimum movement gap within the groove for smooth forward and backward sliding, while effectively suppressing wobbling caused by excessive gap.
