Description

Technical Field

[0001] The present application belongs to the technical field of electric vehicle battery replacement, and in particular relates to a double-compartment slide for an electric vehicle battery replacement system. Background Art

[0002] With the increasing popularity and application of electric vehicles, battery swapping stations (battery swapping stations) have become a crucial infrastructure for addressing the issue of electric vehicle range. Traditional electric vehicle charging methods, due to their lengthy charging times, are unable to meet users' demands for faster range, leading to the emergence of battery swapping. However, existing battery swapping technologies and system designs still face some challenges and shortcomings in practical applications.

[0003] Battery swap technology with cache locations: In some battery swap station designs, in order to achieve a smooth battery swap process, the system sets up a cache location for temporarily storing the feed batteries removed from the electric vehicle. The specific process is as follows: the removed feed battery is first placed in the cache location, the fully charged battery is moved from the docking location to the RGV (rail-mounted transport vehicle), and then the fully charged battery is loaded into the battery compartment of the electric vehicle. Afterwards, the feed battery in the cache location is moved to the battery compartment of the battery swap station for charging or subsequent processing.

[0004] While this design improves the fluidity of battery replacement, it has the disadvantage of taking up a lot of space. The battery swap station requires additional space for buffering slots, which not only increases the overall footprint of the station but also requires larger boxes to accommodate more battery storage slots, increasing site usage costs and equipment manufacturing costs.

[0005] Another existing technology eliminates the docking station, but instead places the removed feed battery directly into the battery compartment. A new, fully charged battery is then loaded onto the RGV and installed on the electric vehicle. This design omits the buffer station, but the battery replacement process becomes more lengthy. Utility Model Content

[0006] In response to the shortcomings in the relevant technologies, the utility model provides a double-compartment slide for an electric vehicle battery replacement system, which solves the technical problem in the existing technology of low efficiency of battery replacement stations due to the complex battery replacement process or the large amount of space occupied.

[0007] In one possible embodiment, a double-bin slide for an electric vehicle battery replacement system is provided, comprising: two oppositely arranged slides, guide rails I are respectively provided on the upper planes of the two slides, guide rails II are respectively provided on the opposite inner surfaces of the two slides, sliders I and sliders II are respectively provided on guide rails I and guide rails II, and sliders I and sliders II slide along guide rails I and guide rails II respectively; the two parts of the first group of battery trays are respectively connected to the two corresponding sliders I through the upper slide seat, and the first group of battery trays are located on the upper planes of the two slides; the two parts of the second group of battery trays are respectively connected to the two corresponding sliders II through the lower slide seat, and the second group of battery trays are located On the opposite inner surfaces of the two slides; two groups of four-section synchronous belts, the two sections of synchronous belts in each group are arranged around the upper plane and the lower plane of the same slide, and a servo motor, a reducer, a coupling and a synchronous pulley are set at the same end of the two slides; the servo motor is connected to the coupling through the reducer, and the output shaft of the coupling is connected to the synchronous pulley, and the two synchronous belts are respectively installed on the synchronous pulley on the side where the servo motor is installed and the other side at the opposite ends of the two slides; the upper slide is connected to the synchronous belt clamping plate, and the synchronous belt clamping plate is connected to the synchronous belt located on the upper plane of the slide; the lower slide is connected to the synchronous belt clamping block mounting seat, and the synchronous belt clamping block mounting seat is connected to the synchronous belt located on the lower plane of the slide.

[0008] In a possible implementation, the two parts of the first battery support plate are respectively mounted on the upper slide via an upper support frame and an upper support plate.

[0009] In a possible embodiment, it also includes: a water retaining assembly, including a water retaining bracket and a water retaining plate, the water retaining bracket is installed on the inner surface of the slide and is placed above the guide rail II; the water retaining plate is installed on the water retaining bracket, and the water retaining plate is placed between the planes where the first battery tray and the second group of battery trays are located.

[0010] In a possible implementation manner, one or more water retaining components are provided.

[0011] In a possible implementation, the system further includes: a scale plate, which is disposed on the upper slide and has an indicating end, and the indicating end indicates the scale on the slide.

[0012] In a possible embodiment, it also includes: a sensor plate II and a slide proximity switch, the sensor plate II is arranged on the upper slide; the slide proximity switch is arranged at both ends of the slide, and when the sensor plate II contacts the slide proximity switch, the slide proximity switch is triggered and a trigger signal is sent; the servo motor is controlled to stop by the trigger signal of the slide proximity switch.

[0013] Based on the above technical solution, the double-compartment slide for the battery replacement system of an electric vehicle of the present invention realizes the two-way rapid replacement of the battery of the electric vehicle by setting a double slide structure, synchronous belt drive and servo motor control. Specifically, the first group of battery trays is used to carry fully charged batteries, and the second group of battery trays is used to receive feed batteries, and the synchronous movement in and out of the batteries is achieved through bidirectional sliding. The sliding paths of the two battery trays are staggered and operate independently, avoiding mutual interference during the sliding process, and ensuring a smooth replacement process of the fully charged battery and the feed battery. The servo motor drives the synchronous belt to drive the upper slide and the lower slide to slide along the guide rail, so that the fully charged battery is accurately moved into the battery compartment of the electric vehicle, and the feed battery is moved to the battery rack for charging, thereby solving the problem of low battery replacement efficiency of existing electric vehicles.

DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying drawings in the examples of this application to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

Therefore, a feature specified as "first," "second," or "third" may explicitly or implicitly include one or more of such features.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0029] In order to solve the technical problem in the prior art that battery replacement stations are inefficient due to the complicated battery replacement process or the large amount of space occupied, the present application provides a dual-compartment slide for an electric vehicle battery replacement system.

[0030] See also Figure 1-Figure 3 In one possible embodiment, a double-bin slide 5 is used for a battery replacement system of an electric vehicle, including: two oppositely arranged slides 51, guide rails I 52 are respectively provided on the upper planes of the two slides 51, and guide rails II 53 are respectively provided on the relatively inner surfaces of the two slides 51; sliders I 54 and sliders II 55 are respectively provided on the guide rails I 52 and guide rails II 53, and the sliders I 54 and sliders II 55 slide along the guide rails I 52 and guide rails II 53 respectively. The two parts of the first group of battery trays 56 are respectively connected to the two corresponding sliders I 54 through the upper slides 561, and the first group of battery trays 56 are located on the upper planes of the two slides 51; the two parts of the second group of battery trays 57 are respectively connected to the two corresponding sliders II 55 through the lower slides 571, and the second group of battery trays 57 are located on the relatively inner surfaces of the two slides 51.

[0031] Two groups of four-section synchronous belts 58, the two sections of synchronous belts 58 in each group are arranged around the upper and lower planes of the same slide 51, and a servo motor 59, a reducer 510, a coupling 511 and a synchronous pulley 512 are set at the same end of the two slides 51. The servo motor 59 is connected to the coupling 511 through the reducer 510, and the output shaft of the coupling 511 is connected to the synchronous pulley 512. The two synchronous belts 58 are respectively installed on one side of the servo motor 59 and the synchronous pulley 512 on the other side at both ends of the two slides 51. The upper slide 561 is connected to the synchronous belt clamping plate 513, and the synchronous belt clamping plate 513 is connected to the synchronous belt 58 located on the upper plane of the slide 51. The lower slide 571 is connected to the synchronous belt clamping block mounting seat 514, and the synchronous belt clamping block mounting seat 514 is connected to the synchronous belt 58 located on the lower plane of the slide 51.

[0032] The double-bin slide is arranged relative to the two slides 51, and cooperates with the sliders Ⅰ54 and Ⅱ55 on the guide rails Ⅰ52 and guide rails Ⅱ53 to realize the sliding and fixing of the battery tray. The first group of battery trays 56 slide along the guide rail Ⅰ52 through the upper slide 561 and the slider Ⅰ54, and the second group of battery trays 57 slide along the guide rail Ⅱ53 through the lower slide 571 and the slider Ⅱ55. The two groups of battery trays adopt a two-way synchronous transmission method to alternately complete the transportation and replacement operations of the feeding battery and the fully charged battery, and are independent of each other during operation, without interfering with the entire The battery replacement process includes controlling the servo motor 59 to drive the synchronous belt 58 to move the fully charged battery from the battery rack to the first group of battery trays, and at the same time move the feeding battery to the second group of battery trays and move the slide to the bottom of the electric vehicle. Through precise positioning and synchronous control, the loading of the fully charged battery and the unloading of the feeding battery are realized to ensure that the entire process is carried out efficiently and automatically. The servo motor 59 drives the synchronous belt 58 to rotate, and the synchronous belt clamping plate 513 and the synchronous belt clamp block mounting seat 514 are used to drive the tray to perform precise displacement to ensure precise control of the tray position.

[0033] The double-bin slide has a compact structure. The two slides realize multi-directional sliding of the battery tray through the upper and lower guide rails, and can simultaneously carry out battery loading and unloading operations, greatly improving the efficiency of battery replacement. The servo motor drives the synchronous belt system to achieve automatic and precise control of the battery tray, reducing the complexity of operation and manual participation, and improving the stability and reliability of the system.

[0034] In another possible embodiment, guide rail I 52 and guide rail II 53 can use other forms of linear guides, such as ball guides or magnetic levitation guides, to adapt to different environmental requirements. The synchronous belt drive system can be replaced with a chain drive or gear drive system to enhance durability and load capacity under special conditions. At the same time, the servo motor 59 can be replaced with other types of motors as needed, such as a stepper motor or a brushless DC motor, to meet different precision and response speed requirements.

[0035] See also Figure 3 In a possible embodiment, the two parts of the first battery support plate 56 are respectively installed on the upper slide 561 through the upper support frame 562 and the upper support plate 563.

[0036] The upper support frame 562 and the upper support plate 563 provide stable support for the first group of battery support plates 56, ensuring that the batteries can be firmly fixed on the support plates and slide smoothly through the sliding cooperation between the upper slide seat 561 and the slider I54, thereby realizing precise movement of the battery support plates.

[0037] This structure improves the stability and load-bearing capacity of the battery tray by adding an upper support frame 562 and an upper support plate 563, ensures the stability and safety of the battery during the sliding process of the tray, and effectively reduces the risk of failure caused by battery shaking or loosening.

[0038] In one possible embodiment, the double-bin slide also includes a water retaining assembly, which includes a water retaining bracket 568 and a water retaining plate 569. The water retaining bracket 568 is installed on the inner surface of the slide 51, above the guide rail II 53, and the water retaining plate 569 is installed on the water retaining bracket and placed between the planes where the first group of battery trays 56 and the second group of battery trays 57 are located.

[0039] The water retaining assembly is fixed to the inner side of the slide 51 through a water retaining bracket, and the water retaining plate is placed above the guide rail II 53, thereby effectively preventing external liquid or dust from entering the key parts of the sliding system, such as the guide rail and slider. This structure ensures the cleanliness and smoothness of the sliding process of the battery tray, especially in an environment with high humidity or possible liquid leakage, which can effectively extend the service life of the system.

[0040] The setting of the water retaining assembly improves the protection capability of the slide system, can effectively block liquid or dust, prevent contamination or damage to key components such as guide rails and motors, and extend the service life of the system. At the same time, the structure is simple, easy to install and maintain, and greatly reduces the failure rate of the system in harsh environments.

[0041] In a possible implementation, one or more water retaining components may be provided to enhance the protection effect of the system.

[0042] By increasing the number of water retaining components, the slide system can be more comprehensively protected in different key areas. For example, water retaining components can be installed near multiple guide rails or battery trays to prevent liquid or dust from affecting sliding parts in multiple areas at the same time. Each water retaining component functions independently to ensure that the slide system can still operate normally under complex working conditions.

[0043] See also Figure 7 and Figure 8 In a possible embodiment, the double-bin slide further includes a scale plate 564 , which is disposed on the upper slide 561 and has an indicating end that indicates a scale 565 on the slide 51 .

[0044] The scale plate 564 is fixed on the upper slide 561, and its indicating end is used in conjunction with the scale 565 on the slide 51. When the battery tray slides along the guide rail, the indicating end of the scale plate moves to the corresponding position, indicating the exact position of the current tray. This design can assist equipment installation and maintenance personnel in finding the zero point when debugging the equipment, and provide a reference for setting the position for system control.

[0045] See also Figure 8In one possible embodiment, the double-bin slide also includes a sensor plate II 566 and a slide proximity switch 567. The sensor plate II 566 is set on the upper slide 561, and the slide proximity switch 567 is set at both ends of the slide 51. When the sensor plate II 566 contacts the slide proximity switch 567, the slide proximity switch 567 is triggered and a trigger signal is sent. The servo motor 59 is controlled by the trigger signal of the slide proximity switch 567 and stops.

[0046] When the battery tray moves to the predetermined position through the slide, the sensor plate II 566 on the upper slide 561 triggers the proximity switch 567 at both ends of the slide 51. The proximity switch sends a signal to control the servo motor 59 to stop running. This method ensures the automatic stop function of the battery tray when it moves to the specified position, avoids excessive sliding of the tray, and provides precise control of the movement of the battery tray.

[0047] In one possible implementation, a bidirectional battery swapping method for an electric vehicle utilizes the dual-storage slide system of any of the above implementations. The method includes the following steps:

[0048] Control the fully charged batteries to move from the battery rack to the first battery support plate 56 of the double-compartment slide;

[0049] Control the double-bay slide to move to the bottom of the electric vehicle feed battery to be replaced;

[0050] Control the feed battery to move to the second battery tray 57;

[0051] Controlling the movement of fully charged batteries from the first battery tray 56 into the battery compartment of the electric vehicle;

[0052] The control feed battery is moved from the second battery tray 57 into the battery rack and charged.

[0053] First, the control system of the electric vehicle drives the first group of battery trays 56 to slide through the servo motor 59 and the synchronous belt transmission system of the double-bin slide, and moves the fully charged batteries on the battery rack to the upper tray of the double-bin slide. Then, the slide system moves the battery tray to the bottom of the battery compartment of the electric vehicle. Then, through the sliding mechanism of the battery tray, the feeding battery is moved to the second group of battery trays 57. Then, the system controls the first group of battery trays 56 to accurately place the fully charged batteries into the battery compartment of the electric vehicle. Finally, by controlling the second group of battery trays 57, the feeding battery is slid from the tray into the battery rack for charging. The entire process is precisely positioned by the slide proximity switch 567, and efficient two-way battery replacement operation is achieved through the automatic control of the servo motor.

[0054] In one possible implementation, the operation of controlling the feed battery to move from the second battery tray 57 into the battery rack includes the following steps:

[0055] Control the servo motor 59 to start, driving the second battery support plate 57 to slide along the slide 51;

[0056] When the slide proximity switch 567 is triggered by the sensor sheet II 566, the servo motor 59 is controlled to stop running.

[0057] When the feeding battery needs to be moved from the second group of battery trays 57 into the battery rack, the system first starts the servo motor 59, drives the slider II 55 to drive the tray to slide along the guide rail II 53. When the second group of battery trays moves to the predetermined position, the sensor plate II 566 on the upper slide 561 triggers the slide proximity switch 567. After receiving the stop signal, the servo motor 59 immediately stops the sliding of the tray, so that the feeding battery falls accurately into the battery rack for charging.

[0058] By controlling the start and stop of the servo motor, precise movement of the battery tray and safe loading and unloading of the feed battery are achieved; the slide proximity switch 567 provides real-time feedback to ensure the accurate movement of the tray, effectively avoiding the occurrence of batteries sliding over or under position, and further improving the safety and stability of the system.

[0059] Other embodiments of the present invention are as follows:

[0060] 1. The double-bin slide has two battery temporary storage trays, one high and one low. The placement of different batteries is determined by the guide block, which can be used to transport batteries of two different sizes.

[0061] 2. The double-bin slide has two sets of battery trays, that is, two battery transport positions. Figure 5 Each set of battery pallets can transport large and small batteries. The two sets of pallets move on the slide through sliders and guide rails. The two sets of battery pallets are connected together through four sets of synchronous belts. The synchronous belt pulleys are driven by the main motor of the slide to drive the synchronous belt movement, so that the two sets of pallets can run synchronously and staggered, which greatly improves the battery transportation speed. Figure 5 .

[0062] As another implementation method, the battery swapping process and mechanism at the battery swapping station are described as follows;

[0063] The utility model provides a battery swapping station system for reducing the occupied volume of the battery swapping station without reducing the battery swapping time. The existing technologies include:

[0064] 1. The battery swap station sets up a cache position for the removed batteries. After the feed battery removed from the vehicle is placed in the cache position, the fully charged battery is moved from the docking position to the RGV, and then the fully charged battery is installed on the vehicle. It is best to move the cache position battery to the battery compartment; see Figure 4 .

[0065] Disadvantages of existing technology 1: The cache space temporarily takes up more space, and the box of the battery swap station also needs to be larger;

[0066] 2. Cancel the docking position, put the checked battery into the battery compartment, and then move a new battery to the RGV;

[0067] Disadvantages of existing technology 2: The battery replacement time is too long. After the battery on the car is disassembled, it needs to be sent to the battery warehouse first, and then another battery is transported, which adds more time and is not a good experience for customers.

[0068] This utility model describes a battery swap process and mechanism that eliminates the buffer position, reduces the area occupied by the battery swap station and the size of the box, and adopts a double-layer design from the docking position to the RGV conveyor mechanism. Before the battery swap, a fully charged battery is prepared on the lower layer, the removed feed battery is moved from the RGV to the upper layer, the feed battery is transported from the upper layer to the docking position, and the fully charged battery is transported from the lower layer to the RGV. Figure 5 .

[0069] A1 and A2, B1 and B2 are two groups of battery lifting mechanisms, with upper and lower layers, which reciprocate left and right on the slide rails through belts;

[0070] A1 and A2 are responsible for transporting the dismantled old batteries, while B1 and B2 are responsible for transporting the fully charged new batteries to be installed.

[0071] First, place the fully charged new battery on B1B2, move A1 and A2 to the removed feed battery, lift the battery, then move A1A2 to the right and B1B2 to the left synchronously; the two sets of lifting mechanisms move synchronously to reduce the transportation time; after the battery replacement is completed, move the A1A2 battery to the battery rack, A1A2 to the left, and B1B2 to the right to return to the starting point.

[0072] 1. This solution adopts a two-layer conveying mechanism design, which reduces the number of cache positions without reducing the battery replacement speed, reducing the cost of the battery replacement station while retaining the battery replacement experience; it adopts a double-layer conveying mechanism, which is in the form of a battery replacement cart instead of a double-layer conveyor belt; it adopts a lifting and moving method to transport batteries.

[0073] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0074] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the same. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solutions of the present application. They should all be included in the scope of the technical solutions for which protection is requested in the present application.
