[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Embodiment 1: please refer to Figures 1-4 The utility model provides a kind of high-hardness flame-retardant automobile air conditioner control panel shell, including outer shell body 1, equidistantly setting has installation pipe 2 on outer shell body 1, installation pipe 2 is provided with ring group 3, ring group 3 includes outer ring sleeve 31 and inner ring sleeve 32, inner ring sleeve 32 is set in the inside of outer ring sleeve 31, vertical moving slot 38 is set in the inside of outer ring sleeve 31, guide rod 35 is slidably arranged in moving slot 38, guide rod 35 is fixedly installed on inner ring sleeve 32, spring 36 is arranged on the circumferential side of guide rod 35, spring 36 is connected outer ring sleeve 31 and inner ring sleeve 32, vertical sliding slot 22 is set on the inner wall both sides of installation pipe 2, lower plate 37 is fixedly arranged on the left and right sides of the bottom of inner ring sleeve 32, lower plate 37 is adapted with sliding slot 22, the bottom end of sliding slot 22 is connected with transverse slot 23;

[0023] Transverse slot 23 is composed of positioning slot 232 and inclined slot 231, positioning slot 232 is connected with sliding slot 22 by inclined slot 231, the low end of inclined slot 231 is connected with positioning slot 232;

[0024] Fixed slot 21 is set in the top of sliding slot 22, and the size of fixed slot 21 is greater than the size of sliding slot 22;

[0025] The top of the outer ring 31 is fixedly provided with an upper plate 33 at both front and rear ends, which is adapted to the fixed slot 21;

[0026] The outer side of the upper plate 33 is provided with anti-skid lines 34.

[0027] Specifically, the outer shell 1 needs to be fixed in the car first. When installing the ring group 3, the control pipeline first passes through the ring group 3, the lower plate 37 is aligned with the sliding groove 22, the lower plate 37 slides into the outer shell 1 along the sliding groove 22, the ring group 3 is rotated, so that the lower plate 37 enters the transverse slot 23 from the sliding groove 22, and enters the positioning slot 232 along the inclined slot 231. In this process, the spring 36 is stretched, when the ring group 3 is rotated by 90 degrees, the lower plate 37 enters the positioning slot 232, at the same time, the upper plate 33 corresponds to the fixed slot 21, the user releases the outer ring 31, so that the spring 36 loses the external force restriction, and then restores the original state to drive the outer ring 31 to move towards the installation pipe 2, so that the upper plate 33 enters the fixed slot 21, and the upper plate 33 and the lower plate 37 are fixed in the installation pipe 2 under the action of the spring 36, and then a button is installed at one end of the control pipeline;

[0028] When disassembling, reverse operation can be performed, so that the ring group 3 can be conveniently installed and disassembled without disassembling the outer shell 1, thereby facilitating the extraction of the control pipeline for maintenance. For example, when the control pipeline fails, the entire panel shell does not need to be disassembled, only the ring group 3 needs to be taken out according to the specific operation, so that the control pipeline can be maintained, which greatly saves the maintenance time and workload, and improves the vehicle maintenance efficiency;

[0029] The anti-skid lines 34 on the outer side of the upper plate 33 increase the friction force during operation, which facilitates the maintenance personnel to grip and rotate the ring group 3 during installation and disassembly, and improves the operation accuracy and convenience;

[0030] The design of the moving slot 38 in the inner ring 31 and the guide rod 35 limits the rotation of the inner ring 32, so that the inner ring 32 can only move in the vertical direction along the moving slot 38. During the rotation process of installing and disassembling the ring group 3, the spring 36 only bears axial tension, and will not be subjected to torsion due to the rotation of the ring, effectively protecting the elastic performance and service life of the spring 36, and ensuring the normal function of the ring group 3 and the stability of the equipment;

[0031] The outer shell 1 is made of PC (polycarbonate) with different weight parts as the base, and polyphenylene sulfide, composite modifier (ABS / vitrified fiber / oxidized graphene composite modifier) with different weight parts. PC (polycarbonate) has good mechanical properties, impact resistance and dimensional stability, etc., which can provide a certain hardness and strength basis for the outer shell, and ensure that the outer shell is not easy to deform or damage during use. The vitrified fiber in the composite modifier has the characteristics of high strength and high modulus, which can significantly enhance the hardness and mechanical properties of the material. At the same time, the unique two-dimensional structure and excellent mechanical properties of graphene oxide also help to improve the overall hardness of the material. Polyphenylene sulfide has good chemical stability, high temperature resistance and excellent flame retardant properties. After adding, it can improve the overall high temperature resistance and flame retardant properties of the outer shell, and can maintain good performance in high temperature environment, while enhancing the flame retardant ability of the outer shell, making it more in line with safety requirements.

[0032] Working principle: First, fix the outer shell 1 in a suitable position in the car, control the pipeline to pass through the ring group 3, including the outer ring sleeve 31 and the inner ring sleeve 32, so that the lower plates 37 on the left and right sides of the bottom of the inner ring sleeve 32 are aligned with the vertical sliding grooves 22 on the inner wall of the installation pipe 2. The lower plates 37 slide into the outer shell 1 along the sliding grooves 22, rotate the ring group 3, and in this process, the lower plates 37 enter the horizontal grooves 23 composed of the positioning grooves 232 and the inclined grooves 231 from the sliding grooves 22, and enter the positioning grooves 232 along the inclined grooves 231. The spring 36 is stretched, and when the ring group 3 is rotated by 90 degrees, the lower plates 37 enter the positioning grooves 232. At this time, the upper plates 33 on the top of the outer ring sleeve 31 on the front and rear ends correspond to the fixed grooves 21 on the top of the installation pipe 2. Loosen the outer ring sleeve 31, and the spring 36 restores its original state and moves the outer ring sleeve 31 towards the installation pipe 2, so that the upper plates 33 enter the fixed grooves 21. Realize the use of the upper plates 33 and the lower plates 37 to fix the ring group 3 in the installation pipe 2 under the action of the spring 36, and then install the button at one end of the control pipeline.

[0033] When the control pipeline fails and needs to be repaired, reverse operation is performed, that is, the ring group 3 is taken out according to the specific operation, the tension of the spring 36 is overcome first, the upper plates 33 are separated from the fixed grooves 21, the ring group 3 is rotated to make the lower plates 37 return to the sliding grooves 22 along the inclined grooves 231 from the positioning grooves 232, and then the lower plates 37 are slid upward along the sliding grooves 22 to take out the ring group 3, so as to facilitate the extraction of the control pipeline for repair.
