DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 11 The vehicle suspension structure based on the shock absorber assembly shown includes a support arm 2, a shock absorber 3 and two groups of connecting arms 1, the two groups of connecting arms 1 are respectively arranged at both ends of the support arm 2, two groups of shock absorbers 3 are arranged, and the two groups of shock absorbers 3 are symmetrically arranged on one side of the support arm 2, and also includes: The protective assembly 6 is composed of a protective cover 601 and four groups of extended protective plates 602. The four groups of extended protective plates 602 are arranged in a ring shape and are equidistantly arranged outside the protective cover 601. The protective cover 601 is fixedly sleeved outside the support arm 2. The four groups of extended protective plates 602 are movably connected to the protective cover 601. like Figures 1 to 11 As shown, by the design that the protective cover 601 is fixedly mounted on the outside of the support arm 2, the protective cover 601 can protect the outside of the support arm 2 to prevent damage when the support arm 2 touches the bottom, and the four groups of extended protective plates 602 are all movably located on the outside of the protective cover 601. Therefore, a double line of defense can be achieved, thereby further improving the service life of the support arm 2.

[0032] The adjustable linkage assembly 9 is provided with four groups, and every two groups of adjustable linkage assembly 9 are symmetrically arranged on the outside of the support arm 2, and the extended protection plate 602 is transmission-connected with the adjustable linkage assembly 9, so that the extended protection plate 602 is close to or away from the center of the support arm 2 through the adjustable linkage assembly 9; like Figures 1 to 11 As shown, since the extended protection plate 602 is designed to be close to or away from the center of the support arm 2 through the adjustable linkage assembly 9, the extended protection plate 602 can be unfolded, thereby protecting the support arm 2 in a larger range.

[0033] The protection drive assembly 5 is provided with two groups, and the two groups of protection drive assemblies 5 are respectively arranged close to the shock absorber 3, and the two groups of adjustable linkage assemblies 9 at the same end are transmission-connected with one group of protection drive assemblies 5.

[0034] like Figures 1 to 11 As shown, through the design of two groups of protection drive components 5 being arranged close to the shock absorber 3, when the shock absorber 3 is performing a shock absorbing operation, the protection drive component 5 can be linked so that the protection drive component 5 cooperates with the adjustable linkage component 9 to realize the simultaneous deployment of multiple groups of extended protection plates 602. Therefore, when the vehicle suspension is performing a shock absorbing operation and is close to the ground, the extended protection plates 602 can be deployed at the same time to protect the support arm 2, thereby quickly maximizing the protection of the support arm 2.

[0035] Furthermore, the outer side of the protective cover 601 is prismatically arranged to fit the extended protective plate 602. Transmission components 605 are arranged at both ends of the extended protective plate 602, so that the extended plate can move outside the protective cover 601 through the transmission components 605. like Figures 1 to 11 As shown, through the design that the outer side of the protective cover 601 is set in a prism shape, because the extended protective plate 602 is a rectangle, the extended protective plate 602 can better fit the outer side of the protective cover 601 with a prism design, so that when the extended protective plate 602 is hit, there is enough stress to receive the collision.

[0036] Further, a transmission plate 604 is rotatably connected between two groups of extended protection plates 602 on one side of the support arm 2. The transmission plate 604 is传动连接 with the adjustable linkage assembly 9, so that the transmission plate 604 approaches or moves away from the support arm 2 through the adjustable linkage assembly 9; As Figures 1 to 11 shown, through the design that the transmission plate 604 is commonly传动连接 between the two groups of extended protection plates 602, when the transmission plate 604 moves through the adjustable linkage assembly 9, the two groups of extended protection plates 602 can be driven to move simultaneously, so as to make the movement of the two groups of extended protection plates 602 more stable and improve the stability of their compression and collision.

[0037] Further, the adjustable linkage assembly 9 includes a track plate 901 and a track rod 903. A sliding groove is formed on one side of the track plate 901. One end of the track rod 903 is movably installed inside the sliding groove, and the other end of the track rod 903 is rotatably connected to the transmission plate 604. The track plate 901 is inclined, and the track plate 901 is活动连接 with the protection driving assembly 5; As Figures 1 to 11 shown, through the design that the other end of the track rod 903 is rotatably connected to the transmission plate 604, when the shock absorber 3 operates, the support arm 2 moves upward, and the track rod 903 can slide along the inclined track plate 901, so as to make the transmission plate 604 move away from the protective sleeve 601 and control the two groups of extended protection plates 602 to move away from the protective sleeve 601 and unfold. Therefore, when the vehicle suspension is shock-absorbed, the extended protection plates 602 can be automatically unfolded to protect the support arm 2.

[0038] Further, the protection driving assembly 5 includes a special-shaped rod 501. The special-shaped rod 501 is arranged in a U shape. Both ends of the opening of the special-shaped rod 501 are rotatably connected with a telescopic rod 904. One end of the movable end of the telescopic rod 904 is rotatably connected with a sliding seat 10. The sliding seat 10 is slidably installed on the upper surface of the track plate 901; The upper end of the shock absorber 3 is provided with a top plate 4, and the upper end of the special-shaped rod 501 is fixedly installed at the bottom of the top plate 4; Both ends of the lower part of the outer side of the special-shaped rod 501 are fixedly installed with positioning plates 11, and the positioning plates 11 are arranged close to the telescopic rods 904. A servo motor 902 is arranged at the lower end of one side of the positioning plate 11. The output shaft of the servo motor 902 penetrates through the positioning plate 11. A through hole is formed at the lower end of one side of the positioning plate 11. One end of the output shaft of the servo motor 902 is fixedly connected with the track plate 901; As Figures 1 to 11As shown, by the design that the upper end of the special-shaped rod 501 is fixedly installed on the bottom of the top plate 4, the position of the special-shaped rod 501 is fixed, and the top plate 4 is mainly used to install the shock absorber 3 on the bottom of the vehicle, so that the position of the top plate 4 is fixed. Therefore, when the support arm 2 performs the supporting shock absorption operation, it moves upward close to the bottom of the vehicle, and the track plate 901 to which the special-shaped rod 501 is fixedly connected through the positioning plate 11 can well guide the movement of the transmission plate 604, thereby realizing the automatic deployment protection of the extended protective plate 602.

[0039] like Figure 7 As shown, a protective shell 12 is disposed on the other side of the positioning plate 11 , and the protective shell 12 wraps the output shaft of the servo motor 902 .

[0040] The design of the protective shell 12 can effectively protect the output shaft of the servo motor 902, thereby preventing the output shaft of the servo motor 902 from being damaged by flying stones and other objects encountered by the vehicle during driving, causing imbalance when the servo motor 902 controls the track plate 901 to rotate.

[0041] It should be noted that, through the design of the servo motor 902 and the positioning plate 11, the inclination angle of the track plate 901 can be changed, so that the optimal inclination angle of the track plate 901 can be selected according to the road conditions of the vehicle. When the shock absorber 3 performs shock absorption operation of the same distance, when the inclination angle of the track plate 901 is close to the vertical angle, the extended protective plate 602 is slightly expanded through the cooperation of the transmission plate 604 and the track rod 903. On the contrary, when the inclination angle of the track plate 901 is close to the horizontal state, the expansion angle of the extended protective plate 602 will become larger, thereby realizing the diversity of the protective mechanism and the applicability to different road conditions, thereby further improving the practicality of the vehicle suspension protection performance.

[0042] Furthermore, the transmission component 605 includes a convex roller 6051, which is rotatably connected to the extension protection plate 602, and a plurality of groups of extension grooves 8 are provided on the outer side of the protection cover 601, and the convex roller 6051 is movably arranged inside the extension groove 8; a plurality of groups of movable grooves 7 are provided on one side of the plurality of groups of extension protection plates 602, and the plurality of groups of movable grooves 7 are slidably connected with the undulating plates 603, and the plurality of groups of undulating plates 603 are fixed to each other, and the plurality of groups of undulating plates 603 on one side are all transmission-connected to the convex roller 6051, a plurality of groups of tooth grooves 15 are provided at the lower part of the extension groove 8, and a gear groove corresponding to the tooth groove 15 is provided at one end of the outer side of the convex roller 6051, so that the convex roller 6051 is meshed and connected with the tooth groove 15 through the gear groove. The multiple groups of undulating plates 603 on one side are all fixedly installed with a pressure plate 6054 at the lower end of the same side, and a transmission groove 14 is opened at one end inside the multiple groups of movable grooves 7 on one side, and the pressure plate 6054 is slidably installed inside the transmission groove 14. Multiple groups of connecting rods 6052 are rotatably connected inside the transmission groove 14, and one group of connecting rods 6052 is fixedly connected to the convex roller 6051. A contact rod 6053 is fixedly installed between two adjacent groups of connecting rods 6052. The contact rod 6053 is arranged in a semicircle, and the contact rod 6053 and the pressure plate 6054 are arranged correspondingly. A return spring 13 is arranged on one side of the multiple groups of undulating plates 603 close to the bottom of the movable groove 7, and one end of the return spring 13 is fixedly installed on the bottom of the movable groove 7; like Figures 1 to 11 As shown, through the design in which one group of connecting rods 6052 is fixedly connected to the convex roller 6051, when the extended protective plate 602 is unfolded, the convex roller 6051 can be driven to cooperate with the tooth groove 15 to control the rotation of multiple groups of contact rods 6053. The contact rods 6053 rely on their own semicircular characteristics to realize the pressure plate 6054 and the return spring 13 to repeatedly move up and down inside the movable groove 7, so that the undulating plate 603 can shake slightly when the extended protective plate 602 is unfolded. Therefore, when the vehicle is traveling on a muddy road section, mud adheres to the surface of the extended protective plate 602, and the undulating plate 603 can break the hardened mud, thereby avoiding a large amount of mud from adhering too much to the extended protective plate 602, affecting its subsequent maintenance and the normal use of the extended protective plate 602.

[0043] The above embodiments are only used to help understand the method and core idea of ​​the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
