Description

Technical Field

[0001] The utility model relates to a walking anti-slip device and a battery swapping station including the same. Background Art

[0002] The existing battery box setting methods of electric vehicles are generally divided into fixed type and replaceable type. Among them, the fixed battery is generally fixed on the vehicle, and the vehicle is directly used as the charging object during charging. The replaceable battery pack is generally fixed on the vehicle by an active installation method. The depleted battery pack can be removed by a battery swapping device, then transported to a charging place for charging operation, and then a fully charged battery pack is taken to the vehicle for replacement operation. Among them, after the replaced battery pack is charged, it is reinstalled on the vehicle.

[0003] At present, the existing battery swapping devices include a shuttle car for battery swapping. The shuttle car needs to move back and forth between the vehicle and the charging place. Since the shuttle car is prone to slipping during walking, it is difficult to align the shuttle car with the vehicle and the charging place, resulting in low battery replacement efficiency and low safety. Especially in cold regions, the ice on the track easily causes the situation that the shuttle car slips and has a large positioning deviation, resulting in the failure of battery pack replacement. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defect that the shuttle car is prone to slipping during walking in the prior art, resulting in low battery replacement efficiency, low safety and failure of battery pack replacement, and provide a walking anti-slip device and a battery swapping station including the same.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0009] In this solution, adopting the above structural form, the limit pad is arranged in the battery swapping channel between the battery swapping position and the charging rack of the battery swapping station and plays an anti-slip role. During the movement of the shuttle car, the limit wheel also moves and walks on the limit pad. The limit wheel does not slip when moving on the limit pad, thus effectively avoiding the slipping phenomenon of the shuttle car during movement and walking, ensuring the accuracy of mobile positioning, improving the battery swapping efficiency and having higher safety.

[0010] Preferably, the limiting pad extends from the battery replacement position to the charging rack within the battery replacement channel;

[0011] Alternatively, the limiting pad is provided in sections and is at least provided at a first position adjacent to the battery replacement position and a second position adjacent to the charging rack.

[0012] In this solution, adopting the above structural form, by arranging the limiting pad throughout between the battery replacement position and the charging rack, the shuttle car will not slip during the whole process of movement, realizing faster movement and higher accuracy of movement positioning, improving the battery replacement efficiency and having higher safety.

[0013] In addition, by arranging multiple sectional limiting pads at least at a first position adjacent to the battery replacement position and a second position adjacent to the charging rack, the shuttle car will not slip when moving to the first position and the second position through the limiting pad, effectively ensuring accurate detection by the sensors at the battery replacement position and the charging rack and realizing precise positioning.

[0026] In this solution, adopting the above structural form, the two sides of the shuttle car move and travel on the limiting pads through the limiting wheels, ensuring that accurate movement and positioning can be achieved on both sides of the shuttle car, improving the battery swapping efficiency, and having higher safety.

[0027] Preferably, the outer peripheral surface of the limiting wheel has a plurality of outwardly protruding first anti-slip teeth.

[0032] In addition, the limiting wheel can also be engaged with the second anti-slip teeth on the limiting pad through the first anti-slip teeth, so that the first anti-slip teeth and the second anti-slip teeth abut against each other, greatly increasing the friction between the limiting wheel and the limiting pad, and further ensuring that the movement and positioning of the shuttle car are more accurate; at the same time, when the first anti-slip teeth are engaged with the second anti-slip teeth, it can play a role in guiding the insertion and alignment, so that the limiting wheel can be corrected and fine-tuned during the walking process, and the movement and positioning accuracy of the shuttle car is higher.

[0064] The present utility model will be more clearly and completely described below by way of embodiments in conjunction with the accompanying drawings, but the present utility model is not limited to the scope of the embodiments.

[0065] Embodiment 1

[0066] An embodiment of the present utility model discloses a battery swapping station. As shown in Figure 1 and Figure 2 , the battery swapping station includes an anti-slip device for walking 100 and a shuttle car 200. The shuttle car 200 can move in the battery swapping channel between the battery swapping position and the charging rack of the battery swapping station. The shuttle car 200 is used to disassemble the battery that needs to be replaced on the electric vehicle at the battery swapping position, and then move to the charging rack to charge the replaced battery; take out the fully charged battery on the charging rack and transport it to the battery swapping position, so as to perform battery swapping operation on the electric vehicle.

[0067] The walking anti-slip device 100 is applied in a battery swapping station. The walking anti-slip device 100 includes a limit wheel 1 and a limit pad 2. The limit wheel 1 is connected to a shuttle car 200 in the battery swapping station to drive the rotation of the limit wheel 1 by the shuttle car 200. The limit pad 2 is arranged in a power swapping channel between a power swapping position and a charging rack in the battery swapping station. The limit wheel 1 cooperates with the limit pad 2 and can move and walk on the limit pad 2. The limit pad 2 is arranged in the power swapping channel between the power swapping position and the charging rack in the battery swapping station and plays an anti-slip role. During the movement of the shuttle car 200, the limit wheel 1 will also be driven to move together, so that during the movement of the shuttle car 200, the limit wheel 1 also moves and walks on the limit pad 2. The limit wheel 1 does not slip when moving on the limit pad 2, thus effectively avoiding the slipping phenomenon of the shuttle car 200 during movement, ensuring the accuracy of mobile positioning, improving the battery swapping efficiency, and having higher safety.

[0068] In one embodiment, the limit pad 2 can extend from the power swapping position to the charging rack in the power swapping channel. The shuttle car 200 moves back and forth in the power swapping channel between the power swapping position and the charging rack. By arranging the limit pad 2 throughout the power swapping channel between the power swapping position and the charging rack, the shuttle car 200 will not slip during the whole process of movement, realizing faster movement and higher accuracy of mobile positioning, improving the battery swapping efficiency, and having higher safety.

[0069] In another embodiment, the limit pad 2 can also be arranged in sections, and is at least arranged at a first position adjacent to the power swapping position and a second position adjacent to the charging rack. The multiple segmented limit pads 2 are respectively arranged, and at least the limit pad 2 is arranged at the first position adjacent to the power swapping position and the second position adjacent to the charging rack, so that the shuttle car 200 will not slip through the limit pad 2 when moving to the first position and the second position, thereby effectively ensuring the accurate detection of sensors at the power swapping position and the charging rack and realizing precise positioning. At the same time, the limit pad 2 does not need to be arranged throughout, reducing costs and being very convenient to use. Of course, in actual use, the limit pad 2 can be arranged not only at the first position and the second position, but also multiple segmented limit pads 2 can be arranged at equal intervals between the power swapping position and the charging rack, so as to ensure that the shuttle car 200 does not slip during movement while taking cost into account.

[0070] As Figure 2 shown, the shuttle car 200 includes walking wheels 201, and the limit wheel 1 is arranged outside the walking wheels 201. The movement and walking of the shuttle car are realized by the rotation of the walking wheels 201. The limit wheel 1 is arranged outside the walking wheels 201, and the limit wheel 1 is directly driven to move and walk by the walking wheels 201, ensuring more accurate movement and walking; at the same time, the limit wheel 1 is installed outside the walking wheels 201, and the installation is very convenient.

[0071] In one embodiment, the radius of the limit wheel 1 is not greater than the radius of the traveling wheel 201, and the difference in radius between the traveling wheel 201 and the limit wheel 1 is less than the height of the limit pad 2. The limit pad 2 is installed on the traveling path of the limit wheel 1 and is located below the limit wheel 1. By the difference in radius between the traveling wheel 201 and the limit wheel 1 being less than the height of the limit pad 2, when the limit pad 2 is set below the limit wheel 1, the sum of the radius of the limit wheel 1 and the height of the limit pad 2 is greater than the radius of the traveling wheel 201, thereby ensuring that the limit wheel 1 and the limit pad 2 cooperate with each other to achieve an anti-slip effect. The limit pad 2 is not provided below the traveling wheel 201 to prevent the traveling wheel 201 from contacting the limit pad 2 and increasing the friction, which affects the traveling efficiency of the shuttle car 200.

[0072] In another embodiment, the traveling wheel 201 travels on the track to drive the shuttle car 200 to travel in a preset direction. The radius of the limit wheel 1 is greater than the radius of the traveling wheel 201, and the difference in radius between the limit wheel 1 and the traveling wheel 201 is less than the height of the track. The track is installed on the traveling path of the traveling wheel 201 and is located below the traveling wheel 201. By the difference in radius between the limit wheel 1 and the traveling wheel 201 being less than the height of the track, when the track is set below the traveling wheel 201, the sum of the radius of the traveling wheel 201 and the height of the track is greater than the radius of the limit wheel 1, thereby ensuring that the traveling wheel 201 and the track cooperate with each other to enable the traveling wheel 201 to travel on the track to drive the shuttle car 200 to travel in a preset direction, achieving accurate movement positioning of the shuttle car 200, improving the battery swapping efficiency, and having higher safety. At the same time, there is space below the limit wheel 1 to set the limit pad 2, ensuring the installation of the limit pad 2, enabling the limit wheel 1 to move and travel on the limit pad 2, thereby effectively preventing the shuttle car 200 from slipping during the movement and travel, ensuring accurate movement positioning, improving the battery swapping efficiency, and having higher safety.

[0073] As Figure 1 shown, the number of the limit pads 2 is two, and the two limit pads 2 are respectively arranged on both sides of the shuttle car 200 along the traveling direction of the shuttle car 200; the number of the limit wheels 1 is at least two, and at least one limit wheel 1 is arranged on each side of the shuttle car 200 along the traveling direction of the shuttle car 200 and cooperates with the corresponding limit pad 2. The limit wheels 1 and the limit pads 2 are arranged on both sides of the shuttle car 200, enabling the two sides of the shuttle car 200 to move and travel on the limit pads 2 through the limit wheels 1, ensuring that both sides of the shuttle car 200 can achieve accurate movement positioning, improving the battery swapping efficiency, and having higher safety.

[0074] In this embodiment, the number of the limit wheels 1 is two and they are respectively located on both sides of the shuttle car 200. Of course, in other embodiments, the number of the limit wheels 1 is multiple and is not limited, to ensure that the shuttle car 200 can move and travel stably without slipping.

[0075] As shown Figure 2 in FIG. Figure 2 , the outer peripheral surface of the limit wheel 1 has a plurality of first anti-slip teeth 11 protruding outward. During the movement of the limit wheel 1, the outwardly protruding first anti-slip teeth 11 can abut against the limit pad 2, and the friction force of the limit wheel 1 during walking is greatly increased through the plurality of outwardly protruding first anti-slip teeth 11, further ensuring that the movement positioning of the shuttle car 200 is more accurate, improving the battery swapping efficiency, and having higher safety.

[0076] In this embodiment, the limit pad 2 has a plurality of inwardly recessed anti-slip grooves 21 along the walking direction of the limit wheel 1. When the limit wheel 1 moves on the limit pad 2, the first anti-slip teeth 11 are correspondingly inserted into the anti-slip grooves 21. During the movement of the shuttle car 200, the limit wheel 1 inserts the first anti-slip teeth 11 into the anti-slip grooves 21 of the limit pad 2 correspondingly, so that the first anti-slip teeth 11 abut against the anti-slip grooves 21, greatly increasing the friction force between the limit wheel 1 and the limit pad 2, and further ensuring that the movement positioning of the shuttle car 200 is more accurate; at the same time, the first anti-slip teeth 11 can play a role in guiding and inserting in place when inserted into the anti-slip grooves 21, so that the limit wheel 1 can be corrected and fine-tuned during walking, and the movement positioning accuracy of the shuttle car 200 is higher.

[0077] The limit pad 2 includes a pad body 22 and a mounting member 23. One end of the mounting member 23 is connected to the pad body 22, and the other end of the mounting member 23 is detachably connected to the battery swapping channel; the anti-slip grooves 21 are provided on the pad body 22. The pad body 22 is installed on the battery swapping channel where the shuttle car 200 moves through the mounting member 23. The mounting member 23 adopts a detachable connection method, so that the limit pad 2 is easy to disassemble and install, and can be quickly removed during non-slip time; at the same time, the original structure of the battery swapping channel is not damaged, which is convenient for replacement and adjustment of the position.

[0078] In this embodiment, the number of the mounting members 23 is multiple, and the multiple mounting members 23 are respectively connected to both sides of the pad body 22 along the walking direction of the shuttle car 200. By respectively installing and connecting the multiple mounting members 23 to both sides of the pad body 22, the pad body 22 is stably installed on the battery swapping channel, realizing higher installation and connection stability of the pad body 22, effectively avoiding the phenomenon of offset and dislocation of the pad body 22 during use, having high movement positioning accuracy, improving the battery swapping efficiency, and having higher safety.

[0079] Specifically, the shape of the mounting member 23 is an L-shaped structure. The vertical structure is used for installing and connecting to the side surface of the pad body 22, and the horizontal structure has a connection hole, and it is convenient to install on the battery swapping channel by using a fastener through the connection hole.

[0080] Of course, in other embodiments, multiple mounting components 23 can also be respectively connected to the lower side of the pad body 22. The mounting components 23 are mounted and connected to the battery swapping channel, and the lower side of the pad body 22 is mounted and connected to the mounting components 23, thereby realizing the mounting and connection of the pad body 22, which is convenient for mounting and connection.

[0081] In this embodiment, the pad body 22 is a chain, which has a simple structure and low cost.

[0082] The walking anti-slip device 100 further includes a connecting member 3 connected between the walking wheel 201 and the limiting wheel 1. The number of the connecting members 3 can be multiple, and the multiple connecting members 3 are evenly spaced along the circumferential direction of the limiting wheel 1. Both ends of the connecting member 3 are respectively connected to the walking wheel 201 and the limiting wheel 1. The limiting wheel 1 is mounted and connected to the walking wheel 201 through the connecting member 3. It is very convenient to mount and set the limiting wheel 1 through the connecting member 3, and the connection stability is high. At the same time, the connecting member 3 is located between the walking wheel 201 and the limiting wheel 1, the overall structure is more compact, the occupied space is small, and the structure is simple.

[0083] In this embodiment, the number of the connecting members 3 is two, and the two connecting members 3 are respectively connected to the two ends on the diameters of the walking wheel 201 and the limiting wheel 1, so that the connection strength between the walking wheel 201 and the limiting wheel 1 is high and the stability is higher.

[0084] Embodiment 2

[0085] As Figure 3 and Figure 4 shown, the same parts of the walking anti-slip device 100 in this embodiment and Embodiment 1 will not be repeated, and only the differences will be described. In this Embodiment 2, the limiting pad 2 has multiple second anti-slip teeth 24, and the first anti-slip teeth 11 are engaged with the second anti-slip teeth 24. During the movement of the shuttle car 200, the limiting wheel 1 is engaged with the second anti-slip teeth 24 on the limiting pad 2 through the first anti-slip teeth 11, so that the first anti-slip teeth 11 and the second anti-slip teeth 24 act against each other, greatly increasing the friction between the limiting wheel 1 and the limiting pad 2, and further ensuring that the movement positioning of the shuttle car 200 is more accurate. At the same time, when the first anti-slip teeth 11 are engaged with the second anti-slip teeth 24, it can play a role in guiding and inserting for alignment, so that the limiting wheel 1 can be corrected and fine-tuned during walking, and the movement positioning accuracy of the shuttle car 200 is higher.

[0086] In this Embodiment 2, the pad body 22 is provided with multiple upwardly protruding second anti-slip teeth 24, and the multiple upwardly protruding second anti-slip teeth 24 are spaced along the length direction of the pad body 22.

[0087] Specifically, the pad body 22 is a timing belt, and different types of pad bodies 22 can be selected and installed according to different working conditions, and it has a simple structure and low cost.

[0088] In the second embodiment, the number of the connecting members 3 is one. One connecting member 3 is concentrically arranged with and connected to the rotating shaft of the shuttle car 200. The connecting member 3, the traveling wheels 201 and the limiting wheels 1 are concentrically arranged. The limiting wheels 1 are mounted and connected to the traveling wheels 201 through one connecting member 3, so that the mounting and connection are convenient, the structure is simple, and the cost is low.

[0090] As Figure 5 and Figure 6 shown, the same parts of the anti-slip device 100 for traveling in this embodiment and those in Embodiment 1 will not be repeated, and only the differences will be described. In the third embodiment, the pad body 22 is a rubber belt. When the limiting wheel 1 moves on the pad body 22, the first anti-slip teeth 11 of the limiting wheel 1 can be inserted into the rubber belt, thereby greatly increasing the friction between the limiting wheel 1 and the limiting pad 2, further ensuring that the movement and positioning of the shuttle car 200 are more accurate; at the same time, the structure is simple and the cost is low.

[0091] In the third embodiment, the mounting member 23 is a pressing plate, and the pressing plate is pressed on the top of the pad body 22. Specifically, the number of the pressing plates is two. One ends of the two pressing plates are respectively pressed on the two ends of the top of the rubber belt, and the other ends of the two pressing plates are detachably connected to the power exchange channel, so as to realize the mounting and connection of the rubber belt. The mounting and connection are convenient and the stability is higher. At the same time, the two pressing plates are arranged at intervals and form a gap exposing the rubber belt. The limiting wheel 1 is in the gap and moves on the rubber belt. The two pressing plates will play a role in limiting the limiting wheel 1, so that the limiting wheel 1 moves along a preset direction, realizing the accuracy of the movement and positioning of the shuttle car 200, improving the power exchange efficiency and having higher safety.
