[0095] Optionally, the limiting member 37 and the slider 32 may be directly connected or indirectly connected, and the connection method may be welding, bonding, clamping, screwing, etc., without limitation.
[0096] Optionally, in one embodiment, as Figure 5 As shown, the limiter 37 is connected to the slider 32 through the support plate 34, and the limiter 37 is installed on the support plate 34 through two bolts. A limit slot 312 is provided on one side of the support member 31 away from the first positioning assembly, and the limiter 37 is received in the limit slot 312.
[0097] When the slider 32 slides along the first direction X relative to the support member 31 driven by the driving module 33, it drives the limit member 37 to move in the limit groove 312. The limit groove 312 is used to limit the movement range of the limit member 37 in the first direction X, thereby limiting the movement range of the slider 32 in the first direction X.
[0098] By configuring the adjustment mechanism to also include a limiter 37 , the support member 31 is provided with a limiter slot 312 , and the limiter 37 is received in the limiter slot 312 , which can limit the movement range of the slider 32 in the first direction X, thereby limiting the adjustment range of the second support member 31 .
[0099] Optionally, a second slide rail (not shown in the figure) is provided on a side of the first side beam 71 facing the second side beam 72 , and the first adjustment structure 30 is suitable for being slidably connected to the second slide rail in the second direction Y.
[0100] Optionally, the second slide rail is arranged on the side of the first side beam 71 facing the second side beam 72, and the support member 31 is slidably connected to the second slide rail. The support member 31 can move relative to the first side beam 71 in the second direction Y to adjust the position of the second support block 82 in the second direction Y.
[0101] By setting the first side beam 71 with a second slide rail, the first adjustment structure 30 is slidably connected to the second slide rail in the second direction Y, and the position of the second support block 82 can be adjusted in the second direction Y to adapt to the production of vehicle models with a large difference in wheelbase. The vehicle hoist 100 has better compatibility and flexibility and is more practical.
[0102] Similarly, the second adjustment structure 40 has the same structure as the first adjustment structure 30 , and the adjustment method of the second adjustment structure 40 and the connection method of the second adjustment structure 40 and the second side beam 72 can refer to the aforementioned first adjustment structure 30 and the first side beam 71 , and will not be repeated here.
[0103] In the description of the embodiments of the present invention, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0104] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
