Detailed Description
Referring to fig. 1, 2, 7 and 8, a head lifter for a vehicle includes a vertical support portion 10 and a slope portion, wherein the bottom surface of the vertical support portion is flush with the bottom surface of the slope portion, the vertical support portion is hollow, a guide block 11 is disposed on the inner side wall of the vertical support portion, the slope portion is provided with a guide groove 21 engaged with the guide block, and the slope portion can be hidden into the vertical support portion or removed from the vertical support portion when the guide block relatively moves along the guide groove.
In the above description, regarding "when the guide block moves relatively along the guide groove, the slope portion can be hidden in the vertical support portion, or the slope portion can be removed from the vertical support portion", in practical operation, the specific content thereof relates to: the guide groove is horizontally arranged, and when the slope part is hidden into the vertical supporting part, the guide block moves forward along the guide groove; when the slope portion is moved out of the vertical supporting portion, the guide block is reversely moved along the guide groove. The ramp section is removed from the vertical support section 10 and the horizontal top surface of the vertical support section engages the ramp of the ramp section.
Referring to fig. 3 to 5, in practice, two lifters according to the present invention are laid on the ground, one in front of the left front wheel of the vehicle and the other in front of the right front wheel of the vehicle, with the slope of each lifter facing the wheels of the vehicle. Then, the automobile is started, the left front wheel and the right front wheel respectively move forward along the slope of the slope part of the corresponding lifter, and the head of the automobile is lifted. When the automobile continues to move forward, the left front wheel and the right front wheel climb to the top surface of the vertical supporting part 10 of the corresponding lifter, and at the moment, the automobile brakes, the parking brake, the left front wheel and the right front wheel stay on the horizontal top surface of the vertical supporting part 10 of the corresponding lifter. Therefore, the head of the automobile is lifted, an operator can lie on the ground, the head of the operator extends into the lower part of the head of the automobile, the oil receiving basin is placed below the oil drain hole of the engine, the oil drain screw is screwed, and the old engine oil in the engine shell flows out and enters the oil receiving basin. After the use of the lifter is completed, the ramp portion is hidden in the vertical support portion.
The slope part comprises a first slope part 20 and a second slope part 30, the first slope part is hollow, a pin shaft 22 is arranged in the first slope, and the second slope part is provided with a pin hole 31 matched with the pin shaft; the pin shaft is located at the tail of the first slope, the pin hole is located at the front end of the second slope, and the slope of the first slope portion is higher than that of the second slope portion. The second ramp portion is rotated to rotate clockwise along the pin 22, and the second ramp portion is rotated into the first ramp portion from the bottom of the first ramp portion and hidden in the first ramp portion. When the lifter is used, the second slope part is rotated anticlockwise, so that the second slope part rotates anticlockwise along the pin shaft 22, the second slope part rotates out from the bottom of the first slope part until the slope of the first slope part is in butt joint with the slope of the second slope part, and the bottom surface of the first slope part is flush with the bottom surface of the second slope part.
The guide grooves 21 are provided on the left and right side walls of the first slope section 20, the guide grooves being horizontally provided, the guide grooves being close to the bottom of the first slope section; the number of the guide blocks 11 is a pair, the pair of guide blocks are arranged in bilateral symmetry, the guide block on the left side is matched with the guide groove on the left side wall of the first slope part, and the guide block on the right side is matched with the guide groove on the right side wall of the first slope part. The guide block 11 does not extend into the cavity of the first slope portion, so as to avoid interference of the second slope portion hidden in the cavity of the second slope portion.
The combined design of the first and second ramp sections 20 and 30 of the present invention enables the ramp design of the lifter to be longer than a single ramp section, the longer ramp can be hidden into the vertical support section 10, and the longer ramp can facilitate the vehicle to gently climb onto the top surface of the vertical support section 10.
Referring to fig. 1 and 6, a lifting plate 12 is disposed on the top of the vertical support part 10, and a driving assembly for driving the lifting plate to lift is disposed on the outer side wall of the vertical support part. The design of the lifting plate is another innovative technology of the invention for the following reasons: the front of the front wheel of the automobile is provided with a bumper of the automobile head, the bottom surface of the bumper is closer to the ground, the bottom of the bumper in front of the front wheel can be contacted with a slope before the front wheel of the automobile climbs the slope of the lifter, namely, the front wheel does not climb the slope, the bottom of the bumper is already contacted with the slope, and if the automobile continues to move forwards, the bumper is damaged; in order to solve the technical problem, the applicant reduces the slope of the slope to make the slope smoother, so that the bottom of the bumper cannot collide with the slope in the process of climbing the front wheel of the automobile onto the slope; however, the slope of the slope is reduced, and if the length of the slope is relatively short, the height of the car head to be lifted is not high, therefore, the lifting plate 12 is designed, after the front wheel of the car climbs the lifting plate, if the car head is not high and the operator cannot conveniently climb to the position below the car head to put oil, the operator can drive the driving assembly to lift the lifting plate 12, and further, the car head is lifted. In the case that the slope of the slope is reduced, the length of the slope can be increased to raise the height of the vehicle head, and the slope can be designed in a segmented manner, such as the first slope part 20 and the second slope part 30 of the invention, so that the slope is completely hidden in the vertical support part 10, and thus, the lifter does not occupy more space when being stored.
Due to the design of the lifting plate 12, the lifter of the present invention also has the function of a jack for lifting the vehicle body and replacing the tire.
As shown in fig. 7 and 8, the driving assembly comprises a left bracket 13 mounted on the left side wall of the vertical supporting part 10, a sleeve 14 pivoted on the left bracket, a worm wheel 15 mounted on the sleeve, a worm 16 engaged with the worm wheel, a screw 17 threaded in the sleeve and passing through the worm wheel and the left bracket, a right bracket 18 mounted on the right side wall of the vertical supporting part, and a guide rod 19 movably engaged with the right bracket; the top end of the screw is fixedly connected with the lifting plate 12, and the top end of the guide rod is fixedly connected with the lifting plate. The worm is pivoted on the left support 13 and connected with the handle, or the wrench can rotate the worm, the worm rotates, the worm wheel drives the sleeve to synchronously rotate, the screw 17 is driven by the internal thread of the sleeve to lift, and the screw drives the lifting plate 12 to lift. The right bracket 18 is provided with a guide hole, a guide rod is matched in the guide hole, and the screw rod can drive the lifting plate to lift linearly under the matching of the guide rod 19 and the guide hole.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description herein, since various changes and modifications can be made in the details of the embodiment and the application range according to the spirit of the present invention.
