Description

Technical Field

[0001] This utility model relates to the field of electric vehicle swapping technology, and in particular to a transfer trolley with a lateral moving platform. Background Technology

[0002] There are currently two main methods for charging electric vehicle batteries: charging stations and battery swapping stations. Charging via a battery swapping station involves driving the electric vehicle into the station, removing the depleted battery, and then swapping it with a fully charged battery. The depleted battery is then transported to the charging unit for charging. The vehicle does not need to wait for the depleted battery to finish charging on-site, resulting in high charging efficiency. This charging mode is called battery swapping.

[0003] The battery swapping station is equipped with a battery swapping cabinet, which in turn is equipped with a transfer trolley. The transfer trolley is configured to transfer batteries between the electric vehicle and the battery swapping cabinet. When the transfer trolley moves to the bottom of the vehicle to pick up the battery, the transfer trolley needs to adjust its position according to the parking position of the electric vehicle so that the carrying platform of the transfer trolley is directly facing the battery compartment of the electric vehicle, allowing the carrying platform to smoothly pick up the battery.

[0004] A transfer trolley with lifting and rotating functions is currently available. The trolley adjusts the height distance between the support platform and the battery compartment of the electric vehicle through lifting. It also adjusts the angular distance between them through rotation. However, when the electric vehicle is parked at the battery swapping station, it may deviate from the centerline. In this case, because the existing transfer trolley lacks lateral movement capability, a horizontal misalignment occurs between the support platform and the battery compartment, leading to unreliable battery reception by the support platform and reduced battery swapping reliability.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0055] In some embodiments of this application, a battery swapping cabinet is provided, which is configured to store fully charged batteries and depleted batteries awaiting recharging.

[0056] The chassis of an electric vehicle has a battery compartment, which houses the batteries.

[0057] This application also provides a transfer trolley 10 with a lateral moving platform, the transfer trolley 10 being configured to transfer batteries between an electric vehicle and a battery swapping cabinet. Figure 2 and Figure 3 The structural diagrams of the transfer trolley 10 are observed from different perspectives.

[0058] For example, both the battery swapping cabinet and the electric vehicle are equipped with battery compartments. Batteries can enter and exit the battery compartments, and the batteries are transported between the battery swapping cabinet and the electric vehicle by a transport trolley.

[0059] For example, both the battery swapping cabinet and the electric vehicle are equipped with battery compartments. The batteries are placed in the battery compartments, which are used as transport vehicles to move between the battery swapping cabinet and the electric vehicle via a transport trolley.

[0060] A battery swapping station is located in front of the battery swapping cabinet. When an electric vehicle needs a battery replacement, the electric vehicle is parked at the battery swapping station, and the transfer trolley 10 moves to the bottom of the electric vehicle to pick up the depleted battery that has been unloaded from the electric vehicle. The transfer trolley 10 then transports the depleted battery to the battery swapping cabinet for charging, and then transports the fully charged battery to the bottom of the electric vehicle for replacement.

[0061] The transfer trolley 10 includes a first movable platform 100. The first movable platform 100 is configured to move along a first moving direction. The first movable platform 100 is configured to move between the battery swapping cabinet and the chassis of the electric vehicle; in other words, the first movable platform 100 is configured to move between the battery swapping cabinet and the battery swapping station. The first moving direction is the horizontal direction between the battery swapping cabinet and the battery swapping station. The movement of the first movable platform 100 enables the transfer trolley 10 to move between the battery swapping cabinet and the battery swapping station.

[0062] Reference Figure 1 A guide rail 700 is provided between the battery swapping cabinet and the battery swapping station. The guide rail 700 extends between the battery swapping cabinet and the battery swapping station. The bottom of the first moving platform 100 is provided with rollers 120 and a drive mechanism (not shown). The drive mechanism is configured to drive the rollers 120 to move along the guide rail 700. The extension direction of the guide rail 700 is the first moving direction.

[0063] This application does not impose specific limitations on the drive mechanism. For example, the drive mechanism includes a motor, the motor's power shaft is connected to a gear, the gear is connected to a rotating rod via a belt, and a roller 120 is provided at the end of the rotating rod.

[0064] The transfer trolley 10 also includes a support platform assembly, which is positioned above the first moving platform 100. The support platform assembly is configured to carry either a battery or a battery compartment. Specifically, in a battery-based transfer configuration, the support platform assembly carries the battery; in a battery-based transfer configuration, the support platform assembly carries the battery compartment.

[0065] The support platform assembly includes a second movable platform 200. The second movable platform 200 is disposed above the first movable platform 100. The second movable platform 200 is configured to move along a second moving direction under the action of the lateral drive mechanism 400. The second moving direction is perpendicular to the first moving direction in the horizontal direction. The moving direction of the second movable platform 200 is perpendicular to the moving direction of the first movable platform 100. The moving direction of the first movable platform 100 (i.e., the first moving direction) is parallel to the length direction of the transfer trolley 10, and the moving direction of the second movable platform 200 (i.e., the second moving direction) is parallel to the width direction of the transfer trolley 10.

[0066] In other words, if the movement of the transfer trolley 10 between the battery swapping cabinet and the electric vehicle is defined as forward and backward movement, then the second moving platform 200 moves laterally left and right under the action of the lateral drive mechanism 400. When the electric vehicle is parked at the battery swapping station, there may be a situation where the electric vehicle deviates from the center line of the battery swapping station. At this time, the left and right lateral movement of the second moving platform 200 is used to adjust the left and right position of the support platform assembly relative to the battery compartment of the electric vehicle.

[0067] The support platform assembly includes a lifting platform 300. The lifting platform 300 is positioned above the second movable platform 200 and configured to move vertically in a direction perpendicular to both the first and second movement directions under the action of a lifting drive mechanism 500. In other words, the lifting platform 300 is configured to move towards or away from the battery compartment of the electric vehicle under the action of the lifting drive mechanism 500.

[0068] The support platform assembly includes a rotary table 900. The rotary table 900 is mounted on the lifting platform 300 and is configured to rotate under the action of the rotary drive mechanism 600.

[0069] The battery swapping cabinet is equipped with an identification device, which includes, but is not limited to, laser sensors and image detection devices. When an electric vehicle is swapping its battery, it parks at the swapping station in front of the cabinet. The identification device detects the electric vehicle's parking position, vehicle model, and other information. The control system of the battery swapping cabinet controls the movement of the transfer trolley 10 based on the detection data from the identification device.

[0070] During battery swapping, the first moving platform 100 first moves along the guide rail 700 to the underside of the electric vehicle's chassis; then, depending on the parking position of the electric vehicle, the lateral drive mechanism 400 drives the second moving platform 200 to move left and right; then, the rotation drive mechanism 600 drives the turntable 900 to rotate, so that the carrier platform assembly can be directly aligned with the electric vehicle's battery compartment; then, the lifting drive mechanism 500 drives the lifting platform 300 to rise to receive the battery or battery compartment; after receiving, the lifting platform 300 descends, and the first moving platform 100 moves along the guide rail 700 to the battery swapping cabinet.

[0071] The transfer trolley 10 of this application achieves forward movement through the first moving platform 100, left and right movement through the second moving platform 200 and the lateral drive mechanism 400, lifting movement through the lifting platform 300 and the lifting drive mechanism 500, and rotational movement through the rotating platform 900 and the rotation drive mechanism 600. In this way, the transfer trolley 10 can achieve multi-dimensional adjustment movement, so that the transfer trolley 10 can be accurately positioned under the battery compartment of the electric vehicle, so that the transfer trolley 10 can reliably receive the battery or battery compartment, thereby improving the reliability of battery swapping.

[0072] In some embodiments of this application, reference is made to Figures 4 to 6 , Figure 4 This is a structural diagram of the first mobile station 100. Figure 5 This is a structural diagram of the second moving stage 200 viewed from the bottom. Figure 6 This is a structural diagram of a transverse drive mechanism 400. The transverse drive mechanism 400 includes a first motor 410, the power shaft of which is connected to a rotating rod 420. The rotating rod 420 extends along the length of the transfer trolley 10, and a first gear 430 is connected to the end of the rotating rod 420. A rack 440 is fixedly mounted on a first moving table 100, extending along the width of the transfer trolley 10. The first gear 430 meshes with the rack 440.

[0073] The first motor 410 drives the rotating rod 420 to rotate, and the rotating rod 420 drives the first gear 430 to rotate. Through the meshing between the first gear 430 and the rack 440, the second moving table 200 moves left and right along the width direction of the transfer trolley 10.

[0074] In some embodiments of this application, the first motor 410 is fixedly disposed on the side of the second moving platform 200 away from the first moving platform 100, that is, the first motor 410 is fixedly disposed on the top of the second moving platform 200. The second moving platform 200 is provided with a first opening 220, and the first gear 430 protrudes from the first opening 220 to mesh with the rack 440.

[0075] The first motor 410 and the rotating rod 420 are located in the space between the second moving platform 200 and the lifting platform 300. The structure is compact and helps to reduce the height of the transfer trolley 10.

[0076] In some embodiments of this application, the second moving stage 200 is provided with a second opening 230, and the first motor 410 has a portion located within the second opening 230, so as to further reduce the space occupied by the first motor 410, which is beneficial to further reduce the height of the transfer trolley 10.

[0077] In some embodiments of this application, the first motor 410 is connected to two rotating rods 420, and each rotating rod 420 is provided with a first gear 430 at its end. Correspondingly, the top of the first moving platform 100 is provided with two racks 440, which helps to improve the reliability of the left and right movement of the second moving platform 200.

[0078] In some embodiments of this application, a bearing seat 450 is fixedly provided on the second moving stage 200, and the rotating rod 420 passes through the bearing seat 450, which helps to improve the rotation reliability of the rotating rod 420.

[0079] In some embodiments of this application, a first guide portion 110 is provided on the upper part of the first moving stage 100, and a second guide portion 210 is provided on the bottom of the second moving stage 200. The first guide portion 110 and the second guide portion 210 slide in cooperation to further improve the reliability of the left and right movement of the second moving stage 200.

[0080] For example, the first guide part 110 is a slide rail (denoted as the first slide rail), and the second guide part 210 is a slider (denoted as the first slider).

[0081] In some embodiments of this application, a rotary table 900 is disposed above a lifting platform 300, and the rotary table 900 is configured to carry a battery or a battery compartment. A lifting drive mechanism 500 is disposed between the second moving platform 200 and the lifting platform 300, and a rotation drive mechanism 600 is disposed between the lifting platform 300 and the rotary table 900.

[0082] The lifting drive mechanism 500 and the lateral drive mechanism 400 are both located in the space between the second moving platform 200 and the lifting platform 300, resulting in a compact structural layout.

[0083] In other embodiments of this application, the rotary table 900 is disposed below the lifting platform 300, in which case the lifting platform 300 is configured to carry a battery or battery compartment. In this case, the lifting drive mechanism 500 may be disposed between the lifting platform 300 and the rotary table 900, and the rotation drive mechanism 600 may be disposed between the rotary table 900 and the second moving platform 200.

[0084] In some embodiments of this application, reference is made to Figure 7 There are four lifting drive mechanisms 500, which are connected to the four corners of the lifting platform 300. The four lifting drive mechanisms 500 are independently controlled.

[0085] After an electric vehicle is parked at the battery swapping station, it may tilt due to differences in tire pressure and uneven weight distribution. In this case, the lifting platform 300 can be adjusted to be parallel to the battery compartment by the independent control of the four lifting drive mechanisms 500, thereby improving the reliability of battery or battery compartment access.

[0086] The lateral drive mechanism 400 is located between the four lifting drive mechanisms 500, resulting in a compact structural layout.

[0087] In some embodiments of this application, the platform assembly further includes four sensing components 800. The four sensing components 800 are connected one-to-one with four lifting drive mechanisms 500 through a control system. The lifting drive mechanism 500 is configured to perform lifting and lowering movements according to the detection signals of the corresponding sensing components 800.

[0088] For example, the sensing element 800 is a proximity sensor, and the sensing element 800 is located at the four corners of the rotating platform 900. When the lifting drive mechanism 500 drives the lifting platform 300 to move towards the battery compartment of the electric vehicle, when the rotating platform 900 approaches the battery compartment, for example, by 2-4 mm, the lifting drive mechanism 500 stops driving the lifting platform 300 to rise, so as to prevent the rotating platform 900 from touching the bottom of the electric vehicle.

[0089] For example, the sensing element 800 is a pressure sensor, and the sensing element 800 is located at the four corners of the rotary table 900. When the lifting drive mechanism 500 drives the lifting table 300 to move towards the battery compartment of the electric vehicle, the pressure sensor detects a pressure signal when the rotary table 900 contacts the battery compartment, and the lifting drive mechanism 500 stops driving the lifting table 300 to rise.

[0090] The four lifting drive mechanisms 500 independently adjust the lifting of the corresponding side of the lifting platform 300 according to the detection signal of the corresponding sensing component 800. In this way, while realizing the lifting movement of the lifting platform 300, the tilt of the lifting platform 300 can also be adjusted.

[0091] In some embodiments of this application, reference is made to Figure 8 The lifting drive mechanism 500 includes an electric push rod 510, a first hinge rod 540, a second hinge rod 550, a slide rail (referred to as the second slide rail 520), and a slider (referred to as the second slider 530).

[0092] The end of the electric push rod 510 is provided with a second slider 530, which is slidably connected to the second slide rail 520. The second slide rail 520 is fixedly mounted on the second moving platform 200. One end of the first hinge rod 540 is hinged to the second slider 530 and the other end is hinged to the lifting platform 300. One end of the second hinge rod 550 is hinged to the second moving platform 200 and the other end is hinged to the rod body of the first hinge rod 540.

[0093] In some embodiments of this application, reference is made to Figure 9 The rotary drive mechanism 600 includes a second motor 610, a second gear 620, and a third gear 630. The second motor 610 is fixedly mounted on the bottom of the lifting platform 300 and is connected to the second gear 620, which is located above the lifting platform 300. The third gear 630 is fixedly mounted on the bottom of the rotary table 900, and the second gear 620 meshes with the third gear 630.

[0094] The second motor 610 drives the second gear 620 to rotate, and the rotation of the rotary table 900 is achieved through the meshing between the second gear 620 and the third gear 630.

[0095] The second motor 610 is fixedly installed below the lifting platform 300, making full use of the space between the lifting platform 300 and the second moving platform 200, resulting in a compact structural layout.

[0096] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0097] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
