[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 and 5 As shown, the vehicle-mounted vibration isolation device in this embodiment includes a mounting platform 1 arranged on the vehicle and telescopically adjustable support members 2 arranged on the four corners of the mounting platform. By adjusting the support members 2, the support members can be separated from the ground, or the support members can be supported on the ground and the mounting platform can be separated from the vehicle.

[0027] The vibration source, such as the generator set 3, is fixedly installed on the mounting platform 1 as a whole. When the vehicle is in normal driving state, the vibration isolation device is set on the vehicle as a whole, and the vibration isolation device is separated from the ground, so that the normal transportation of the generator set can be achieved; when the vehicle is in operation, the extension and contraction of the support member is adjusted so that the support member is supported on the ground, and then the mounting platform is lifted to separate the mounting platform from the vehicle. At this time, the generator set is separated from the vehicle, and the generator set is started to power other equipment on the vehicle. The vibration of the generator set will not have any impact on other equipment on the vehicle, thereby playing a role in complete vibration isolation.

[0028] In this embodiment, the support member 2 is a manual telescopic rod or an electric telescopic rod. A manual telescopic rod is preferably used, and the telescopic adjustment of the telescopic rod can be achieved manually. The manual telescopic rod adopts an existing commercially available structural member and usually adopts a threaded connection drive to achieve telescopic adjustment in the length direction.

[0029] like Figure 2 In this embodiment, the support member 2 is hingedly connected to the mounting platform 1. The support member 2 can rotate up and down relative to the plane of the mounting platform 1 to facilitate storage of the support member, facilitate installation of the vibration isolation device on the vehicle, reduce the space occupied by the device on the vehicle, and avoid interference between the support member and other vehicle components. Specifically, a hinge support 4 is provided between the support member 2 and the mounting platform 1. The hinge support 4 is fixedly connected to the four corners of the mounting platform 1. The support member 2 and the hinge support 4 are hingedly connected. Two sets of fixing holes 401 are respectively provided on the hinge support 4, and the support member 2 is correspondingly provided with pin holes that cooperate with the fixing holes.

[0030] The support member 2 can rotate around the hinge point between the support member and the mounting platform, so that the support member can be rotated to the bottom of the mounting platform when in use. When the support member is rotated to a position perpendicular to the bottom of the mounting platform, the pin holes on the support member (not shown in the figure, located at the position where the fixing pins are set on the support member) are aligned with a group of fixing holes 401, and fixing pins 5 are inserted through the fixing holes 401 and the pin holes to fix the support member in this position. At this time, the support member can be adjusted to achieve support for the mounting platform by the support member; the support member can be rotated to above the mounting platform when stored. When the pin holes on the support member are rotated to align with another group of fixing holes 401, fixing pins 5 are inserted through the fixing holes 401 and the pin holes to fix the support member to the mounting platform.

[0031] Support frames 6 for placing support members are respectively provided at the four corners of the installation platform 1; the support frames 6 serve to provide auxiliary support for the support members.

[0032] Elastic members 7 are provided on the mounting platform 1 at corresponding positions of the four support members. One end of the elastic member 7 is fixedly mounted on the mounting platform 1, and the other end is connected to a pull rope 8. The other end of the pull rope 8 is connected to the support member 2. The elastic member 7 and the pull rope 8 are located within the rotation plane of the support member. Preferably, the elastic member 7 is a tension spring, and the tension spring, the pull rope, and the support member are located within the same plane. During the large-angle rotation of the support member 2 on the mounting platform 1, the tension spring is provided to provide a tensioning force to the support member, which can provide a certain force to the support member during its rotation, making it more labor-saving when the support member is lowered or stored, thereby facilitating the use of the device.

[0033] The installation platform 1 is provided with a guide assembly near the hinge point between the support and the installation platform. The guide assembly is provided between the hinge point and the elastic member. The pull rope 8 is passed through the guide assembly. The guide assembly is used to limit the position of the pull rope on the installation platform. Figure 3 and 6 In this embodiment, the guide assembly includes two guide wheels 10 arranged side by side on the surface of the mounting platform. The two ends of the guide wheels 10 are respectively connected to the hinge support 4. The pull rope 8 is arranged between the two guide wheels 10. When the support member 2 rotates up and down, the pull rope 8 can be wound around the two guide wheels 10 respectively. The guide wheels 10 are provided with an annular limiting groove that cooperates with the pull rope to limit the position of the pull rope.

[0034] A guide wheel 9 is provided at one hinged end of the support member 2. One end of the pull rope 8 passes through two guide wheels 10 and is arranged on the guide wheel 9, and then connected to the support member 2. The setting of the guide wheel and the guide wheel limits the position of the pull rope between the mounting platform and the support member, ensuring the consistency and reliability of the direction of the pull rope force during the rotation of the support member.

[0035] By setting a guide assembly and a guide wheel to limit the position of the pull rope on the mounting platform and the support member, the direction of the force of the tension spring remains unchanged during the rotation of the support member, thereby providing a stable force for the support member.

[0036] A limiting mechanism is provided between the mounting platform 1 and the vehicle for limiting and fixing the mounting platform on the vehicle. Figure 4 In this embodiment, the limiting mechanism includes a plurality of limiting holes 11 provided on the mounting platform and limiting posts 12 provided on the vehicle chassis subframe to cooperate with the limiting holes. The limiting posts 12 extend through the mounting platform and extend above the mounting platform. The limiting posts restrict the mounting platform's position on the vehicle and guide the mounting platform as it moves up and down.

[0037] An end cap 13 is provided at the end of the limiting column 12. The diameter of the end cap 13 is larger than that of the limiting hole 11. The end cap is provided to limit the upward and downward movement of the mounting platform on the vehicle chassis subframe, ensuring the safety of the device during use. The limiting column 12 here adopts a variable cross-section rod structure, so that the cross-sectional dimensions of the upper portion are smaller than the cross-sectional dimensions of the lower portion. In this way, when the mounting platform is placed on the vehicle chassis subframe, the limiting column and the limiting hole fit together perfectly, effectively positioning the mounting platform. When the mounting platform is raised, a certain gap can be created between the limiting hole and the limiting column, thereby preventing the mounting platform and the limiting column from contacting each other when the vibration source vibrates, thereby preventing the vibration from being transmitted to the vehicle.

[0038] Locking mechanisms are provided on the mounting platform 1 at locations corresponding to the limiting holes 11. These mechanisms include a locking sleeve 14 provided on the mounting platform and a locking rod 15 disposed within the sleeve. The locking rod 15 can slide horizontally within the sleeve. The limiting posts 12 are each provided with a locking hole 16 that cooperates with the locking rod. The locking rod slides into the locking hole 16 when sliding horizontally. The locking mechanism facilitates both securing and releasing the mounting platform from the vehicle chassis subframe, making operation simple and convenient.

[0039] The description and drawings of the present invention are considered to be illustrative rather than restrictive. On the basis of the present invention, those skilled in the art can make some substitutions and modifications to some of the technical features according to the disclosed technical content without creative work, and all of them are within the scope of protection of the present invention.
