The embodiment of the invention provides a chassis suspension structure, which is applied to a vehicle and comprises the damping structure, wherein the damping structure is arranged at the bottom of the vehicle, a first connecting
In the present embodiment, referring to fig. 11 in combination with the aforementioned fig. 1 to 10, the damping structure further includes one or more connecting
Alternatively, the first connecting
Optionally, the free ends of the two connecting
Alternatively, as shown in fig. 12, a bar structure is disposed on a side of the two connecting
As an implementation solution of the present invention, as shown in fig. 13, at least one
According to the chassis suspension structure provided by the embodiment of the invention, the damping structure is adopted to arrange the
The embodiment of the invention also provides a vehicle which comprises a vehicle body main body, a driving device and the chassis suspension structure.
Specifically, the chassis suspension structure includes the damping structure according to the above embodiment, and with reference to fig. 11, the driving member of the driving device may be installed in the
In some embodiments, in order to facilitate the rotation of the first connecting
It is thus understood that, in conjunction with the above description, the external device may be a vehicle, and the external device may include a second external element that is a vehicle body, a first external element that is a drive device, and a third external element that is a rotation shaft body. Therefore, when the vehicle runs on a rugged and flat road, the wheels of the vehicle can be attached to the ground as much as possible through the relative rotation and centering design of the first connecting
Of course, it is understood that the chassis suspension structure may be disposed at a rear driving device of the vehicle according to the requirement, and is not particularly limited herein.
Therefore, the vehicle provided by the embodiment of the invention adopts the chassis suspension structure in the embodiment, so that the bumpy feeling or shaking feeling can be effectively reduced when the vehicle moves on an undulating road, and the vehicle can move more stably to adapt to different road conditions.
It is to be understood that the above-described embodiments are merely illustrative of some, but not restrictive, of the broad invention, and that the appended drawings illustrate preferred embodiments of the invention without limiting its scope. This invention may be embodied in many different forms and, on the contrary, these embodiments are provided so that this disclosure will be thorough and complete. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and modifications can be made, and equivalents may be substituted for elements thereof. All equivalent structures made by using the contents of the specification and the attached drawings of the invention can be directly or indirectly applied to other related technical fields, and are also within the protection scope of the patent of the invention.
