Description

Technical Field

[0001] The invention belongs to the technical field of electric carriers, and in particular relates to a motor differential assembly driven carrier and application thereof in a stereo garage. Background Art

[0002] With the increase in population, people's living space is getting smaller and smaller, land resources are extremely scarce, and there are almost no parking spaces. The number of parking spaces is far from meeting the parking demand. In order to meet the needs of parking, people began to use a large number of mechanical parking equipment to solve the problem of insufficient parking spaces. The vigorous development of mechanical parking equipment has led to the emergence of highly automated and integrated mechanical parking equipment. More and more people are pursuing the space utilization of parking equipment while also pursuing the high efficiency of the operation speed of parking equipment. Stereoscopic parking garages can meet this requirement. High space utilization, high operating efficiency, intelligent unmanned participation, front-end entry and exit, and other friendly user experiences are favored by more and more people.

[0003] However, due to the limited space, most of the existing mechanical parking equipment enters the garage from the front and exits the garage from the back, which has low efficiency in storing and retrieving vehicles. At present, there are many types of mechanical parking equipment on the market, and the parking methods are different. They are roughly divided into lifting and horizontal movement, vertical lifting, plane movement, stacking, etc. There are the following disadvantages: 1) The user experience is poor and requires high driving skills; 2) The system installation and debugging are complicated and require high infrastructure; 3) The comprehensive use efficiency is not high, and the equipment idle rate is high due to inconvenient use and management: 4) Especially in the early old residential areas, most of the underground parking garages have insufficient net height to install conventional mechanical three-dimensional parking equipment.

[0004] At present, many underground parking garages have "extra" spaces behind the parking spaces near the passages due to the constraints of the site and building structure. However, once the front parking spaces are occupied, the "extra" through parking spaces in the back row cannot be used as parking spaces to store and retrieve vehicles. If other types of mechanical parking equipment are installed, the metal columns of the mechanical parking equipment will block the use of vehicles entering and exiting the through parking spaces in the back row.

[0005] Since the net height of underground parking garages in old residential areas built in the early days is mostly less than 3.5 meters, conventional two-story mechanical parking equipment cannot be installed and used. If the two-story mechanical parking equipment is not conventionally installed, the vehicles in the upper mechanical parking spaces need to be moved out of the lower ground parking spaces, which is very cumbersome in actual use. Because every time the upper mechanical parking spaces are accessed, the owners of the lower ground parking spaces must move their cars out of the passage no matter what time of night or how busy they are at work; this is difficult to do every time. Summary of the invention

[0006] In view of the shortcomings of the prior art and the fact that most of the early underground parking garages in old residential areas have insufficient clear height to install conventional mechanical three-dimensional parking equipment, the present invention provides a motor differential rear axle assembly driven transporter with high vehicle storage and retrieval efficiency and low cost, and its application in three-dimensional parking garages.

[0007] In order to achieve the above object, the technical solution of the present invention is as follows:

[0009] A side beam is provided on each of the left and right sides of the carrier platform, and a support frame is provided at the rear end of the carrier platform, and the support frame and the side beam are on the same horizontal plane. The side beam on one side of the carrier platform is provided with the positioning walking pulley, and the positioning walking pulley slides along the positioning walking track groove placed on the ground; the side beam on the other side of the carrier platform is provided with the positioning rotating electromagnetic locking pin, and the positioning rotating electromagnetic locking pin is located at the rear end of the side beam and fixed on the stage walking slideway; the electromagnetic lock buckle is placed on the ground, and the positioning rotating electromagnetic locking pin is inserted into it when the carrier rotates, so that the carrier as a whole is fixed and idle on one side under the driving action of the motor differential assembly, and the other side completes a 90-degree rotation along an arc to walk;

[0010] There are two walking rotating guide wheels, which are respectively installed on both sides of the front ends of the two side beams. The two walking rotating guide wheels are pushed or pulled by the configured electric push-pull rods to guide the walking direction. The two electric push-pull rods are welded and fixed to the front part of the carrier platform;

[0011] The motor differential rear axle assembly is located in the middle of the rear end of the support frame, and is connected to running wheels driven by the differential assembly through half shafts arranged at both ends, and the running wheels driven by the differential assembly are fixed to the support frame through half shafts;

[0012] The motor differential rear axle assembly includes two planetary gears, two sun gears, two output shafts and a differential side bevel gear; the two planetary gears are symmetrically fixed on the extension plate of the differential side bevel gear and the gears of the two planetary gears are arranged opposite to each other, the two sun gears are respectively fixed on the two output shafts, and the differential side bevel gear is sleeved on an output shaft, so that the sun gear on the output shaft is meshed with the two planetary gears, and the sun gear on the other output shaft is also meshed with the two planetary gears and the two output shafts are on the same axis; the differential side bevel gear is meshed with the gear on the input shaft of the drive motor.

[0013] Furthermore, the carrier platform includes a table panel, a structural frame and an inclined guide slope, wherein the structural frame is evenly distributed on the table panel, the rear end of the table panel is connected to the support frame, and the inclined guide slope is fixed to the front end of the table panel.

[0014] Furthermore, four to six positioning pulleys are evenly arranged at the bottom of one side beam of the carrier platform.

[0015] Furthermore, a protective cover is provided above the travel rotating guide wheel, and the protective cover covers the travel rotating guide wheel and the electric push-pull rod.

[0016] The present invention also provides an application of a motor differential rear axle assembly driven transporter in a stereo garage, which is realized based on the motor differential rear axle assembly driven transporter and a single-arm column lifting parking device.

[0017] Furthermore, the single-arm column lifting parking device includes a single-arm column and a vehicle loading platform, and the right or left side beam positioning walking pulley of the motor differential rear axle assembly driven transporter can be placed in a positioning walking track groove on the ground along the other side of the bottom of the single-arm column; the vehicle loading platform is located above the motor differential rear axle assembly driven transporter and moves up and down along the single-arm column.

[0018] Furthermore, the motor differential rear axle assembly driven transporter has the following two applications in the stereo garage: (A) and (B):

[0019] (A) Avoid vehicles entering or exiting through parking spaces at the rear row;

[0020] (B) Low-rise garages are installed to allow for access to upper parking spaces.

[0021] Furthermore, any of the following applications:

[0022] (a1) Avoiding vehicles entering and exiting through parking spaces at the rear row: When the motor in the motor differential rear axle assembly driven transporter is driven, the bevel gear on the side of the differential drives the two sun gears to rotate through the two planetary gears provided thereon, and the positioning rotating electromagnetic lock pin installed on the sliding track on one side is inserted into the electromagnetic lock buckle fixed on the ground under the electromagnetic action, and then the transporter platform is locked and fixed with the electromagnetic lock pin and the ground lock buckle, and the transporter platform driven by the motor differential rear axle assembly is fixed and idle on the inside, and the outside is driven by the driving force to complete a 90° rotation along the arc trajectory and then move forward along the staged walking slide track, so as to avoid the vehicles entering and exiting the vehicle access channel space at the rear row;

[0023] (b1) Low-rise garage installation to avoid parking spaces on the upper level: Motor differential rear axle assembly drive transporter Combined with the low-height special car loading platform installed with the single-arm column lifting parking equipment, it is used as the lower parking space installation Use to realize three-dimensional parking.

[0024] More specifically, The tail of the low-height special loading platform is dropped down and installed at an angle. The front end of the low-height special vehicle loading platform can be movably bent around the connecting axis; when the low-height special vehicle loading platform falls to the ground, the front end of the low-height special vehicle loading platform is supported by the ground and is flush with the rear end of the low-height special vehicle loading platform; when the low-height special vehicle loading platform is raised to park the car, the front end of the low-height special vehicle loading platform is pressed down by the gravity of the parked car and bends downward, and the parking height is reduced; this is because the rear end of the low-height special vehicle loading platform utilizes the drop in the front of the vehicle to reduce the installation height and the front end of the low-height special vehicle loading platform is pressed down by the gravity of the parked car, so that the parking height of the upper parking space of the three-dimensional parking equipment can be reduced.

[0025] Furthermore, the motor differential rear axle assembly driven transporter is combined with a stereo garage with a low-height dedicated vehicle loading platform. It can be installed in an underground parking garage between 2.9 and 3.4 meters, which is relatively lower than the normal parking height.

[0026] Beneficial effects: The present invention is used in conjunction with the low-height single-column lifting mechanical parking equipment, which mainly solves the problem of requiring three-dimensional parking spaces due to the restriction of the net height of the underground garage between 2.9 and 3.4 meters, and the problem of some through parking spaces being unable to store and retrieve cars due to the lack of vehicle access channels after parking in the front parking spaces. However, vehicles can be stored and retrieved in the through parking spaces in the rear parking spaces, and the front parking space vehicles carried by the carrier placed on the front parking spaces are moved out to avoid the access channels. The present invention makes it easier and more user-friendly for users who use the carrier to store and retrieve cars. There is no need to reverse, and they can drive in and out directly. The technical requirements for driving the car into the parking space are low. It is easier and more convenient for users to store and retrieve cars, and the overall parking efficiency is correspondingly increased. It is suitable for the underground parking lots in old residential areas that were built earlier and generally have limited net height. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Example 2

[0047] The application of the motor differential rear axle assembly driven transporter in the stereo garage is realized based on the motor differential rear axle assembly driven transporter and the single-arm column lifting parking device; Figures 4 to 5 As shown, the single-arm column lifting parking device (30) includes a single-arm column (26) and a vehicle loading platform (27); a positioning walking pulley (2) on the right or left side beam (11) of the motor differential rear axle assembly driven transporter (28) can be placed in a directional walking track groove (3) on the ground along the other side of the bottom of the single-arm column (26); the vehicle loading platform (27) is located above the motor differential rear axle assembly driven transporter (28) and moves up and down along the single-arm column (26).

[0048] like Figure 7 and Figure 8 As shown, the specific application is to avoid vehicles entering and exiting through parking spaces in the rear row:

[0049] 1) In the motor-differential rear axle assembly driven transporter, the bevel gear on the side of the differential drives the two sun gears to rotate through the two planetary gears arranged thereon, and the positioning rotating electromagnetic lock pin installed on the sliding track on one side is inserted into the electromagnetic lock buckle fixed on the ground by electromagnetic action, so that the transporter platform is locked and fixed with the electromagnetic lock pin and the ground lock buckle, and the transporter platform driven by the motor-differential rear axle assembly is fixed and idle on the inside, and the outside is driven by the driving force to complete a 90° rotation along the arc trajectory and then move forward along the staged walking slide track, so as to avoid the vehicle access channel space for the vehicles in the rear row of the through parking space;

[0050] 2) The vehicles in the upper parking spaces of the rear row of through parking spaces are parked and retrieved by the single-arm column lifting parking device installed here; the vehicles in the ground parking spaces on the lower level are parked and retrieved by the car owners themselves.

[0051] Among them, a single-arm column lifting mechanical parking device is adopted. Since the single-arm column is installed on the side of the front parking space, the front and rear of the front parking space are open and connected without any obstacles. To store and retrieve vehicles in the rear through parking space, the vehicle on the motor differential rear axle assembly driven transporter parked in the front parking space only needs to follow the transporter to move out and rotate along the walking trajectory, avoiding the passage required for vehicles to enter and exit the rear through parking space, thereby achieving the purpose of storing and retrieving vehicles in the through parking space.

[0052] Example 3

[0053] The application of the motor differential rear axle assembly driven transporter in the stereo garage is realized based on the motor differential rear axle assembly driven transporter and the low-height single-arm column lifting stereo parking device; Figure 6 As shown, the single-arm column lifting parking device comprises a single-arm column (26) and a low-height special vehicle loading platform (29); a positioning walking pulley (2) of the right side beam (11) or the left side beam of the motor differential rear axle assembly driven transporter (28) can be placed in a positioning walking track groove (3) on the ground along the other side of the bottom of the single-arm column (26); the low-height special vehicle loading platform (29) is located above the motor differential rear axle assembly driven transporter (28) and moves up and down along the single-arm column (26).

[0054] The specific application is the installation in low-height garages to avoid storing and retrieving vehicles in upper parking spaces: the motor differential rear axle assembly driven transporter is combined with a low-height special vehicle loading platform installed with a single-arm column lifting parking device, which is installed and used as a lower parking space to achieve three-dimensional parking.

[0055] like Fig. 9 As shown, the rear end of the low-height special vehicle loading platform is dropped down and installed at an angle, and the front end of the low-height special vehicle loading platform can be movably bent around the connecting axis; when the low-height special vehicle loading platform falls to the ground, the front end of the low-height special vehicle loading platform is supported by the ground and is flush with the rear end of the low-height special vehicle loading platform; when the low-height special vehicle loading platform is raised to park the car, the front end of the low-height special vehicle loading platform is pressed down by the gravity of the parked car and bends downward, and the parking height is reduced; this is because the rear end of the low-height special vehicle loading platform utilizes the drop in the front of the vehicle to reduce the installation height and the front end of the low-height special vehicle loading platform is pressed down by the gravity of the parked car, so that the parking height of the upper parking space of the three-dimensional parking equipment can be reduced.
