Wherein the first direction F 1 Perpendicular to the top of the cab, in particular in the embodiment shown in fig. 1-3, the first direction F 1 The height direction of the vehicle, so that the operating portion 111 can be operated to drive the end of the transmission assembly 120 away from the driving portion 112 to move along the first direction F 1 And the air guide sleeve 210 is lifted or lowered, so that the air guide sleeve 210 rotates relative to the top of the cab, the included angle between the air guide sleeve 210 and the top of the cab is changed, and the height adjustment of the air guide sleeve 210 can be conveniently realized.
In some embodiments, the operating portion 111 drives the driving portion 112 in a lever manner to drive an end of the transmission assembly 120 away from the driving portion 112 along the first direction F 1 Up or down.
It can be understood that, by using the lever principle, the operation portion 111 can drive the driving portion 112 with less effort, and thus can change the included angle between the air guide sleeve 210 and the top of the cab with less effort, so as to adjust the height of the air guide sleeve 210.
In some embodiments, referring to fig. 2 and 3, the transmission assembly 120 includes at least one set of gear assemblies, each set of gear assembliesA gear assembly includes a pinion gear 121 and a rack gear 122 in driving connection, the rack gear 122 being arranged in a first direction F 1 And (4) extending.

In some embodiments, referring to fig. 1-6, the transmission assembly 120 includes two sets of gear assemblies, wherein one set of gear assemblies includes a driving gear 121 and a rack 122 that are engaged with each other, and the other set of gear assemblies further includes a driven gear 123 engaged between the driving gear 121 and the rack 122.
As the driving portion 112 is configured to be alternatively in contact with the driving gear 121 of one of the at least one gear assembly, it can be understood that the driving portion 112 is configured to be alternatively in contact with the driving gear 121 of one of the two sets of gear assemblies, as illustrated in the embodiment shown in fig. 1-6, and the right-side gear assembly includes the driven gear 123. When the driving portion 112 is connected to the driving gear 121 of the left gear assembly (as shown in fig. 3 and 4), the driving gear 121 of the left gear assembly is driven to rotate reversely, so as to drive the rack 122 of the left gear assembly to move along the first direction F 1 Lowering may cause the pod 210 to rotate relative to the top of the cab and reduce the angle between the pod 210 and the top of the cab.
When the driving part 112 is connected to the driving gear 121 of the right gear assembly (as shown in fig. 5 and 6), the driving part can drive the right gear assemblyThe driving gear 121 rotates clockwise to drive the driven gear 123 to rotate reversely, so that the rack 122 of the right gear assembly can rotate along the first direction F 1 And then the pod 210 is rotated with respect to the top of the cab, and the angle between the pod 210 and the top of the cab is increased.
Thus, the driving part 112 may be in contact connection with the driving gear 121 of the left or right gear assembly as required to change an included angle between the pod 210 and the top of the cab, thereby achieving the ascending or descending of the height of the pod 210.
In some embodiments, referring to fig. 3, the driving gear 121 includes a gear body 1211 and a plurality of dialing teeth 1212 disposed on the gear body 1211 and spaced apart from each other in a circumferential direction of the gear body 1211. The driving portion 112 is configured to alternatively contact with the dialing teeth 1212 of the driving gear 121 of one set of at least one gear assembly and extend between two adjacent dialing teeth 1212 of the driving gear 121, and the driving portion 112 is configured to be operatively connected to the plurality of dialing teeth 1212 sequentially by the operating portion 111.
It can be understood that the driving portion 112 is in contact connection with the current shifting tooth 1212, the driving portion 112 drives the shifting tooth 1212 and the corresponding driving gear 121 to rotate by a certain angle through the operating portion 111, and further drives the second end 212 of the pod 210 to ascend or descend through the transmission assembly 120, so as to adjust the height of the pod 210; in this process, the next dialing tooth 1212 rotates to contact with the driving portion 112, and the driving portion 112 drives the next dialing tooth 1212 and the corresponding driving gear 121 to rotate by a certain angle through the operating portion 111 again, so as to adjust the height of the pod 210 again. Thus, the height of the pod 210 can be adjusted steplessly by the height adjusting device 100, and the reliability of the operation can be improved.
