Description

Technical Field

[0001] This utility model belongs to the field of new energy battery swapping station technology, and in particular relates to a wheel alignment mechanism for battery swapping stations that can reduce damage to internal components. Background Technology

[0002] In new energy vehicle battery swapping stations, a centering mechanism is used to center and position the front and rear wheels of the vehicle in preparation for the next step of replacing the electric vehicle.

[0003] Existing wheel alignment mechanisms typically use a lead screw structure to drive the linear movement of the push plate. For example, Chinese utility model patent CN214450854U discloses a wheel alignment device for a new energy battery swapping station, which includes: two slide rails and their upper sliders, the two slide rails being arranged in parallel; a drive mechanism, including: a lead screw and its upper nut, the lead screw being arranged in parallel between the two slide rails through two lead screw supports; a drive motor and a reducer, the output shaft end of which is connected to one end of the lead screw through a coupling; and an alignment push frame, the bottom sides of which are connected to the sliders on the two slide rails.

[0004] During routine use of the battery swapping station, the applicant discovered that some vehicles have mud and snow adhering to their wheels. When the vehicle enters the station, the pressure from the push plate causes the tires to deform. This deformation creates gaps between the mud and snow and the tires, allowing the mud and snow to fall onto the rollers under the wheels in the alignment mechanism. These gaps may then lead to damage to internal components such as the lead screw. Furthermore, if the mud and snow have a high moisture content, they can also cause corrosion of the internal components of the alignment mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a wheel alignment mechanism for a battery swapping station that can reduce damage to internal components, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wheel alignment mechanism for a battery swapping station that can reduce damage to internal components, comprising a vehicle platform, a lead screw drive assembly on the vehicle platform, a push plate at the output end of the lead screw drive assembly, an outer receiving groove on the push plate, an opening above the outer receiving groove, the length of the outer receiving groove being greater than the diameter of the wheel, and the length direction of the outer receiving groove being perpendicular to the movement direction of the push plate.

[0007] Preferably, the vehicle platform is further provided with an inner receiving groove and a second drive assembly that drives the inner receiving groove to approach or move away from the inner tire surface of the wheel.

[0008] Preferably, the lead screw drive assembly includes a lead screw, a motor for controlling the rotation of the lead screw, limit rotating seats located at both ends of the lead screw, and a slide table threadedly connected to the lead screw, wherein the push plate is disposed on the slide table;

[0009] Position 1 is defined as the distance between the slide table and the wheel at its furthest point, and position 2 is defined as the distance between the inner receiving groove and the wheel at its furthest point. A fixed pulley 1 is provided on the side of position 1 furthest from the wheel, and a fixed pulley 2 is provided on the side of position 2 furthest from the wheel. A connecting rope 1 and a connecting rope 2 are respectively connected between the slide table and the inner receiving groove. The connecting rope 1 is arranged to pass around the fixed pulley 1, and the connecting rope 2 is arranged to pass around the fixed pulley 2, so that the outer receiving groove and the inner receiving groove can move closer to each other and further away from each other through the movement of the slide table.

[0010] Preferably, the first connecting rope and / or the second connecting rope are provided with elastic sections.

[0011] Preferably, the vehicle platform is provided with a slide rail, and the inner receiving groove is provided with a sliding member that can slide on the slide rail.

[0012] Preferably, the vehicle platform is provided with a clearance groove that allows the sliding member and connecting rope, and connecting rope two to pass through.

[0013] Preferably, a first baffle is provided on the slide table and a second baffle is provided on the lead screw, and the end of the first baffle away from the slide table is always placed inside the second baffle.

[0014] The beneficial effects of this utility model are as follows: By setting an outer receiving groove on the push plate, when the push plate contacts the wheel, the mud, snow and other debris that fall off the tire due to the decrease in adhesion caused by tire deformation can fall onto the outer receiving groove, effectively preventing most of the mud, snow and other debris from falling onto the roller or entering the centering mechanism through the roller, which would cause damage or corrosion to the internal components.

[0015] Although the deformation of the inner side of the tire is not significant when the centering mechanism is used for centering, it may still cause snow, mud and other debris to fall off the inner side of the wheel due to vehicle vibration or snow melting. Therefore, by setting an inner receiving groove, it is possible to effectively prevent mud, snow and other debris attached to the inner side of the wheel from falling onto the roller or internal components.

[0016] Among them, by setting elastic sections on connecting rope one and / or connecting rope two, the outer receiving groove and the inner receiving groove can still effectively collect mud, snow and other debris from the inner and outer sides of the wheel when facing wheels of different widths.

[0017] By setting up baffle one and baffle two, damage to the lead screw can be directly prevented if soil, snow, or other debris falls into the baffle and gets onto the lead screw. Attached Figure Description

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0027] Example:

[0028] See Figure 1A wheel alignment mechanism for a battery swapping station that can reduce damage to internal components includes a vehicle platform. A lead screw drive assembly is provided on the vehicle platform. A push plate 3 is provided at the output end of the lead screw drive assembly. An outer receiving groove 4 is provided on the push plate 3. The outer receiving groove 4 has an opening at the top. The length of the outer receiving groove 4 is greater than the diameter of the wheel. The length direction of the outer receiving groove 4 is perpendicular to the movement direction of the push plate 3.

[0029] The vehicle platform is also equipped with an inner receiving groove 5 and a second drive assembly that drives the inner receiving groove 5 to approach or move away from the inner tire surface of the wheel.

[0030] Among them, see Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The lead screw 8 drive assembly includes a lead screw 8, a motor 6 that controls the rotation of the lead screw 8, a limiting rotating seat 7 located at both ends of the lead screw 8, and a slide 9 threadedly connected to the lead screw 8. In this solution, the motor 6 controls the movement of two lead screws 8 simultaneously. A connecting frame 301 is connected to the slide 9 on both lead screws 8, and the push plate 3 is fixed on the connecting frame 301.

[0031] Position 1 is defined as the distance between the slide table 9 and the wheel at its furthest point, and position 2 is defined as the distance between the inner receiving groove 5 and the wheel at its furthest point. A fixed pulley 19 is located on the side of position 1 furthest from the wheel, and a fixed pulley 25 is located on the side of position 2 furthest from the wheel. A connecting rope 11 and a connecting rope 27 are respectively connected between the slide table 9 and the inner receiving groove 5. The connecting rope 11 passes around the fixed pulley 19, and the connecting rope 27 passes around the fixed pulley 25, so that the outer receiving groove 4 and the inner receiving groove 5 can move closer and further apart through the movement of the slide table 9. Specifically, the vehicle platform includes a vehicle platform 1 and a base plate 2 arranged vertically. The lead screw 8 drive assembly is placed on the base plate 2. A connecting seat 1 24 and a connecting seat 23 are provided on the base plate 2. The fixed pulley 19 is located on the connecting seat 1 24, and the fixed pulley 25 is located on the connecting seat 23. The connecting rod is placed on the connecting seat 23. Connector 1 20 and connector 3 16 are provided on the inner receiving groove 5. Connector 22 and connector 4 18 are provided on the slide table 9. The two ends of connecting rope 1 21 are connected to connector 1 20 and connector 22 respectively. The two ends of connecting rope 2 17 are connected to connector 3 16 and connector 4 18 respectively. Connector 1 20, connector 22, connector 3 16 and connector 4 18 can all be bolts with nuts. The connection and fixation of connecting rope 1 21 and connecting rope 2 17 are achieved by putting the two ends of connecting rope 1 21 and connecting rope 2 17 onto the bolts and clamping them with nuts. In order to avoid interference of connecting rope 1 21 after it wraps around the fixed pulley 19, in this embodiment, a clearance fixed pulley 25 is provided on the limiting rotating seat 7 near the connecting seat 24.

[0032] The fixed pulley 19, the fixed changing pulley 2, the connecting rope 1 21, and the connecting rope 2 17 together constitute the second drive assembly.

[0033] Among them, the connecting rope 21 and / or the connecting rope 17 are provided with elastic sections. Specifically, the connecting rope 21 and the connecting rope 17 can be divided into two sections. The elastic section between the two ends of the connecting rope 21 and the connecting rope 17 is a spring, or the elastic element 1 and the elastic element 2 can be made of elastic material themselves.

[0034] The vehicle platform is provided with a slide rail 12, and the inner receiving groove 5 is provided with a sliding member 13 that can slide on the slide rail 12. The sliding member 13 is provided with a roller 14 that can move along the slide rail 12 to enhance the flexibility of the sliding member 13 on the slide rail 12.

[0035] The vehicle platform 1 is provided with a clearance groove 101 that allows the sliding member 13 and connecting rope one and connecting rope two 17 to pass through.

[0036] Among them, see Figure 3The slide table 9 is provided with a first baffle 10 set on the lead screw 8, and the limiting rotating seat 7 is provided with a second baffle 11 set on the lead screw 8. The end of the first baffle 10 away from the slide table 9 is always placed inside the second baffle 11.

[0037] Working principle and process:

[0038] This solution provides an outer receiving groove 4 on the push plate 3. When the push plate 3 contacts the wheel, mud, snow, and other debris that fall off the tire due to the decrease in adhesion caused by tire deformation can fall onto the outer receiving groove 4. This effectively prevents most of the mud, snow, and other debris from falling onto the roller 14 or entering the centering mechanism through the roller, which could cause damage or corrosion to the internal components.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
