Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile battery replacement, in particular to a battery replacement carousel with a unilateral rail for RGV and a battery replacement station. BACKGROUND

[0002] The battery replacement station is a device for automatically, quickly and simply replacing batteries to solve the problem of long charging time of electric vehicles, break through the obstacles of short driving range, difficult charging and long charging time, accelerate the popularization of electric vehicles and achieve energy-saving and zero-emission of automobiles.

[0003] The most important component in the battery replacement station is the RGV battery dismounting mechanism. Whether the battery is replaced depends on whether the RGV unlocking platform unlocks or installs the battery. The form of RGV is slightly different for different vehicle models, but the function is basically the same. The RGV needs to first dismount the depleted battery on the electric vehicle and transfer it to the charging area, and then carry the fully charged battery in the charging area to the battery replacement area and load it onto the electric vehicle.

[0004] Oftentimes, due to site restrictions, the actual space of the battery replacement station is limited. Generally, only one entrance for the electric vehicle is provided in the battery replacement area. In order to facilitate the driver to smoothly drive the electric vehicle into and out of the battery replacement area, a battery replacement carousel is usually provided in the battery replacement area. The driver drives the electric vehicle into the battery replacement area and parks it on the battery replacement carousel. After the RGV completes the battery replacement work, the battery replacement carousel rotates to make the front of the electric vehicle face the entrance, and the driver can drive the electric vehicle out. During the battery replacement, the RGV moves back and forth between the carousel in the battery replacement area and the charging area. The track of the RGV extends from the carousel to the charging area on one side. Due to the rotation of the carousel, the connection between the track on the carousel and the track outside the carousel is disconnected. When the RGV passes through the disconnected track connection, the wheels of the RGV are easily stuck, resulting in the RGV unable to run. SUMMARY

[0005] 1. Technical problem to be solved by the present application

[0006] In view of the problem that the wheels of the RGV are easily stuck when the RGV passes through the disconnected track connection in the prior art, resulting in the RGV unable to run, the present application provides a battery replacement carousel with a unilateral rail for RGV. When the RGV passes through the disconnected track connection, the wheels of the RGV are not easily stuck, thereby ensuring the continuous operation of the RGV.

[0014] Further, a reinforcing rod is arranged along the length direction of the RGV bearing frame, and the reinforcing rod is close to the side of the RGV track with the distance D1 from the middle axis L.

[0015] Further, a rotating mechanism is arranged below the carousel body, and the rotating mechanism drives the carousel body to rotate around the center of the carousel body, and the center is on the middle axis L.

[0016] Further, the rotating mechanism comprises a planetary gear driven by a driving mechanism, a driven gear ring and a bearing ring, the planetary gear drives the driven gear ring to rotate around the center of the driven gear ring in the bearing ring, and the center is on the middle axis L.

[0017] Further, a wheel positioning device is arranged on the carousel body, and when a vehicle is parked on the wheel positioning device, the direction from the front to the rear of the vehicle is perpendicular to the direction of the middle axis L.

[0018] Further, an entrance platform is further included, and the entrance platform cooperates with the wheel positioning device to form a vehicle passageway.

[0019] The application also provides a battery swap station, comprising a charging area and a battery swap area separated by a partition wall, and the above-mentioned battery swap turntable with an RGV single-side track, wherein the RGV track extends from one end of the turntable body to the charging area, so that the RGV can pass between the charging area and the battery swap area.

[0020] Further, the partition wall is provided with two walls, which form a vehicle travel space in cooperation with the entrance platform; in a non-rotating state, the length direction projection of the partition wall is perpendicular to the RGV track.

[0021] Further, the partition wall is provided with an avoidance space for the rotation of the turntable body.

[0022] 3. Beneficial effects

[0023] Compared with the prior art, the technical scheme provided by the application has the following beneficial effects:

[0024] (1) The battery swap turntable with an RGV single-side track of the application is characterized in that the connection positions of the RGV tracks above and outside the turntable body are disconnected, which facilitates the rotation of the turntable body. The two RGV tracks are different in distance from the central axis L of the turntable body in the direction of RGV travel, so that the connection positions of the two tracks are not on the same straight line of the turntable body. When the RGV passes through the disconnected connection positions, the wheels on both sides of the RGV will not pass through the connection positions of the two tracks at the same time, and the wheels on both sides can pass through the disconnected connection positions in sequence. Therefore, the wheels of the RGV will not be stuck, and the RGV can continue to run smoothly.

[0025] (2) The battery swap turntable with an RGV single-side track of the application is characterized in that a gap is arranged between the outer track and the inner track of the RGV track, which facilitates the travel of the auxiliary wheels of the RGV in the gap. The wheel surface of the auxiliary wheel is perpendicular to the track surfaces of the inner track and the outer track on both sides of the gap, which can prevent the RGV from deviating from the track during operation. The auxiliary wheel in cooperation with the gap can correct the travel track of the RGV. The connection positions of the inner tracks above or outside the turntable body are each provided with a chamfer, which can make the auxiliary wheels pass through the connection positions of the tracks more smoothly and transition smoothly.

[0026] (3) The battery swap turntable with an RGV single-side track of the application is characterized in that the plurality of track connecting rods can increase the structural strength between the two inner tracks, increase the load-bearing capacity of the RGV track, and maintain the stable operation of the RGV. The RGV carrying frame mainly plays a supporting role for the entire RGV track, and secondarily increases the structural strength of the turntable body. Since the width direction of the RGV carrying frame is symmetrically arranged about the central axis L, the position of the RGV track on the RGV carrying frame is offset. The reinforcing rod increases the structural strength of one side of the RGV carrying frame and plays a role in balancing the moment.

[0027] (4) The power swap turntable with a unilateral RGV track of the application, the rotating mechanism can drive the turntable body to rotate around the center of the turntable body, and the middle axis L passes through the center to ensure that the RGV tracks above and outside the turntable body can be smoothly connected. The rotating mechanism drives the driven gear ring to rotate through the planetary gear, and then drives the entire turntable body to rotate. The bearing ring can limit the driven gear ring to rotate in the bearing ring, and then ensure that the driven gear ring can also rotate around its center under the action of the planetary gear. The center of the driven gear ring is located on the middle axis L, which can further ensure that the RGV tracks above and outside the turntable body can be smoothly connected.

[0028] (5) The power swap turntable with a unilateral RGV track of the application, the wheel positioning device can make the vehicle stop at a suitable position on the turntable body, facilitating the RGV to swap the power of the vehicle. The parking direction of the vehicle is perpendicular to the middle axis L, and cooperates with the rotation of the turntable body to enable the vehicle to drive in and drive out in the forward direction, reducing the difficulty of vehicle driving for the driver and reducing safety accidents. The entrance platform cooperates with the wheel positioning device to form a vehicle passageway, facilitating the vehicle to drive into the turntable body.

[0029] (6) The power swap station of the application, the charging area and the power swap area are connected through the RGV track, and the RGV can smoothly pass between the charging area and the power swap area. Two partition walls and an entrance platform cooperate to form a vehicle travel space, facilitating the vehicle to drive into the power swap turntable. The length direction projection of the partition wall is perpendicular to the RGV track, which is conducive to fully utilizing the space of the power swap station. The avoidance space of the partition wall facilitates the rotation of the turntable body and avoids interference with the turntable body and the vehicle, increasing the safety of the rotation of the turntable body. Secondly, the existence of the avoidance space is also conducive to the air flow in the power swap station and the heat dissipation of the power swap station. BRIEF DESCRIPTION OF DRAWINGS

[0055] Embodiments

[0056] With reference to Figures 1-6 , the present embodiment provides a battery replacement carousel with RGV single-sided track, which comprises a carousel body 1 and two RGV tracks 2 arranged on the carousel body 1. Both of the two RGV tracks 2 are parallel to the central axis L of the carousel body 1 in the direction of RGV travel, and one end of each of the two RGV tracks 2 extends out of the carousel body 1, and the junctions of the RGV tracks 2 above and outside the carousel body 1 are disconnected from each other. The carousel body 1 is the installation basis of the RGV tracks 2, and the RGV tracks extend outside the carousel body 1, generally to the charging area 8 where the batteries are stored, so that the RGV can conveniently carry the fully charged batteries from the charging area 8 to the carousel body 1 for vehicle battery replacement. The distance from one of the two RGV tracks 2 to the central axis L is D1, and the distance from the other of the two RGV tracks 2 to the central axis L is D2, and D1>D2. As can be seen from the above, the distance from each of the two RGV tracks 2 to the central axis L of the carousel body 1 in the direction of RGV travel is different, so the junctions of the two RGV tracks 2 are not on the same straight line of the carousel body 1. Generally, RGV is designed with at least four wheels to ensure smoothness and stability of operation. When the RGV passes through the disconnected junction, the wheels on both sides of the RGV will not pass through the junctions of the two tracks at the same time, and the wheels on both sides can pass through the disconnected track junctions in sequence, so that the wheels of the RGV will not be stuck, and the RGV can smoothly pass through the junction and continue to operate.

[0057] In the present embodiment, with reference to Figure 3 , Figure 4 and Figure 5 , the RGV track 2 comprises an outer track 201 and an inner track 202, and there is a gap 204 between the outer track 201 and the inner track 202, which is used for the auxiliary wheels of the RGV to travel. The wheel surface of the auxiliary wheels of the RGV is perpendicular to the track surface of the inner track 202 and the outer track 201 on both sides of the gap 204. While the wheels of the RGV travel on the RGV track 2, the auxiliary wheels roll and travel in the gap 204, which can prevent the RGV from deviating from the track during operation, and the auxiliary wheels cooperating with the gap 204 can correct the travel trajectory of the RGV. Further, with reference to Figure 3Chamfers are provided at the joints of the outer rail 201 and inner rail 202 on and outside the turntable body 1. The chamfers are located on the side of the outer rail 201 and inner rail 202 close to the interval 204. The chamfers can make the auxiliary wheel pass through the joint of the rail more smoothly and the transition is smooth.

[0058] In this embodiment, in order to increase the overall structural strength of the RGV track 2, refer to Figure 4 and Figure 5 Multiple track links 203 connect the two inner rails 202, and these links 203 are arranged along the length of the inner rails 202. These links connect the two inner rails 202, increasing their structural stability. Furthermore, since the RGV track 2 itself needs to support the weight of the entire RGV and the battery, its own strength, although reinforced by the track links 203, is insufficient to support the RGV's back-and-forth operation with the battery. Therefore, further structural reinforcement of the RGV track 2 is necessary. (Refer to...) Figure 4 A rectangular RGV support frame 3 is installed below the RGV track 2. In the non-rotating state, the length direction of the RGV support frame 3 is consistent with the direction of the central axis L, and its width direction is symmetrical about the central axis L. The RGV support frame 3 is symmetrically arranged about the center of the turntable 1, which is also the center of rotation, which helps to maintain the structural stability of the entire turntable 1 during rotation. The RGV support frame 3 has multiple support rods 301 perpendicular to the central axis L. The support rods 301 enhance the structural stability of the RGV support frame 3, which helps the RGV support frame 3 support the entire RGV track 2 and also strengthens the structural strength of the entire turntable 1.

[0059] It should be noted that since the RGV support frame 3 is symmetrically arranged about the central axis L, the position of the RGV track 2 on the RGV support frame 3 is offset. Because the RGV runs and transports the battery on the RGV track 2, the offset RGV track 2, bearing the weight of the RGV and the battery, will generate a torque on one side of the RGV support frame 3. To balance this torque, refer to... Figure 5 The RGV load-bearing frame 3 is provided with a reinforcing rod 4 along its length. The reinforcing rod 4 is located near the RGV track 2 at a distance D2 from the central axis L. Therefore, the reinforcing rod 4 increases the structural strength of this side of the RGV load-bearing frame 3, preventing this side from bending downwards due to torque. At least one reinforcing rod 4 is provided, and the number can be increased according to actual design requirements.

[0060] In this embodiment, refer to Figure 2 and Figure 6, the lower part of the rotating disc body 1 is provided with a rotating mechanism 5, the rotating mechanism 5 drives the rotating disc body 1 to rotate around the center of the rotating disc body 1, which is on the middle axis L. The middle axis L passes through the center of the rotating disc body 1, which can ensure that the RGV track 2 above and outside the rotating disc body 1 can be smoothly connected before and after the rotating disc body 1 rotates, preventing deviation. Further, referring to Figure 6 , the rotating mechanism 5 includes a planetary gear 501 driven by a driving mechanism, a driven gear ring 502, and a bearing ring 503. The planetary gear 501 drives the driven gear ring 502 to rotate around the center of the driven gear ring 502 in the bearing ring 503, which is on the middle axis L. The rotating mechanism 5 uses the planetary gear 501 to drive the driven gear ring 502 to rotate, and then drives the entire rotating disc body 1 to rotate. The bearing ring 503 can limit the driven gear ring 502 to rotate in the bearing ring 503, and then ensure that the driven gear ring 502 can also rotate around its own center under the action of the planetary gear 501. The center of the driven gear ring 502 is on the middle axis L, which can further ensure that the RGV track above and outside the rotating disc body 1 can be smoothly connected. It should be noted that, in addition to bearing the RGV and the battery, the rotating disc body 1 also needs to bear the weight of the battery swap vehicle. Therefore, the structure of the planetary gear 501 and the driven gear ring 502 of the rotating mechanism 5 is more important to reduce the lever arm and increase the load-bearing capacity of the rotating mechanism 5, which is beneficial to maintaining the stability of rotation.

[0061] In this embodiment, as a further limitation, referring to Figure 7 , the inner wall of the driven gear ring 502 is provided with a groove, the planetary gear 501 is engaged with the teeth in the groove of the driven gear ring 502, and the upper and lower sides of the planetary gear 501 are provided with limiting structures corresponding to the groove position of the driven gear ring 502. The limiting structure is in contact with the planetary gear 501 and the driven gear ring 502. The limiting structure itself has the function of being rollable and will not hinder the transmission of the planetary gear 501 to the driven gear ring 502. In addition, the limiting structure has a supporting effect. Since the planetary gear 501 is not centrally arranged, and the position of the RGV track 2 on the RGV bearing frame 3 is offset, the limiting structure can enhance the support of the planetary gear 501 to the load.

[0062] In this embodiment, also in order to enhance the load-bearing capacity of the rotating mechanism 5, adapt to the offset track structure, referring to Figure 8 , as a further limitation, also as another limiting way, the planetary gear 501 adopts a bevel gear structure, and correspondingly, the driven gear ring 502 adopts a bevel gear structure matched with the planetary gear 501. In the face of such offset RGV track 2, the load borne by the rotating mechanism 5 is uneven. The bevel gear structure of the planetary gear 501 and the driven gear ring 502 has greater resistance in the radial direction of the planetary gear 501, which can balance part of the offset load and improve the load-bearing capacity of the rotating mechanism 5.

[0063] In this embodiment, referring to Figure 1 and Figure 2 , the turntable body 1 is provided with a wheel positioning device 6, when the vehicle is parked on the wheel positioning device 6, the direction of the vehicle from the front to the rear is perpendicular to the direction of the center axis L. The wheel positioning device 6 can make the vehicle stop at the appropriate position on the turntable body 1, and facilitate the RGV to change the battery of the vehicle. The parking direction of the vehicle is perpendicular to the center axis L, which cooperates with the rotation of the turntable body 1 to make the vehicle drive in and out in the forward direction, reduce the difficulty of driving the vehicle for the driver, and reduce safety accidents. In addition, the position of the vehicle itself on the turntable body 1 can be fine-tuned by the wheel positioning device 6, thereby facilitating the subsequent RGV to change the battery of the vehicle. In addition, an entrance platform 7 is also provided at the entrance and exit of the battery swap station, and the entrance platform 7 cooperates with the wheel positioning device 6 to form a vehicle passageway, which facilitates the vehicle to pass. The entrance platform 7 is mainly composed of a frame and a cover plate, which has good structural strength and can facilitate maintenance of the entrance platform 7.

[0064] In this embodiment, referring to Figure 9 and Figure 10 , a battery swap station includes a charging area 8 and a battery swap area 9, and the charging area 8 and the battery swap area 9 are separated by a partition wall 10. The charging area 8 is used to store batteries and can charge the discharged batteries to a full charge state, and the battery swap area 9 is used for vehicle parking and can be used to remove the discharged batteries from the vehicle by the RGV, and then the full charged batteries are transported from the charging area 8 to the battery swap area 9 and loaded onto the vehicle. The above-mentioned battery swap turntable with a single-sided track of RGV is arranged in the battery swap station, and the RGV track 2 extends from one end of the turntable body 1 to the charging area 8, so that the RGV can pass between the charging area 8 and the battery swap area 9. The partition wall 10 is provided with two, and the two partition walls 10 cooperate with the entrance platform 7 to form a vehicle travel space, which facilitates the vehicle to drive into the battery swap turntable. In the non-rotating state, the length direction projection of the partition wall 10 is perpendicular to the RGV track 2, which is beneficial to fully utilize the space of the battery swap station. The partition wall 10 is provided with an avoidance space 11 for the rotation of the turntable body 1, which facilitates the rotation of the turntable body 1 and avoids the movement interference with the turntable body 1 and the vehicle, thereby increasing the safety of the rotation of the turntable body 1. In addition, the existence of the avoidance space 11 is also beneficial to the air flow in the battery swap station, and is beneficial to the heat dissipation of the battery swap station. Because a plurality of batteries are stored in the charging area 8 and need to be charged, the heat generated by the charging of the plurality of batteries is large, and the battery swap station needs to have a reasonable heat dissipation structure to timely dissipate the heat, so as to avoid the failure or fire disaster of the battery due to the accumulation of heat.

[0065] The above describes the present application and its embodiments in a schematic manner, and the description is not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the above, without departing from the spirit of the present application, similar structural modes and embodiments can be designed without creativity, and all of them shall belong to the protection scope of the present application.
