[0001] This application claims priority to Chinese patent application 202421793511.9 entitled “Battery Swapping System”, filed on July 26, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of new energy vehicle technology, and more specifically, to a battery swapping system. Background Technology

[0003] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. With the increasing prevalence of electric vehicles, battery swapping stations have emerged to ensure timely replenishment of power lost during operation. For electric vehicles, battery swapping technology is a crucial factor in their development.

[0004] In the development of battery swapping technology, how to improve the battery swapping efficiency of the battery swapping system is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] This application provides a battery swapping system, and the technical solution provided by this application can effectively improve the battery swapping efficiency of vehicles.

[0006] Some embodiments of this application provide a battery swapping system, which includes a parking lane and a guiding mechanism. The parking lane has a battery swapping area. The guiding mechanism is disposed within the parking lane and located on the side or top surface of the parking lane. The guiding mechanism includes a guide member and an adjusting member, with the adjusting member connected to the guide member. The adjusting member is used to adjust the position of the guide member relative to the battery swapping area based on vehicle information, so that the guide member can guide the vehicle to move until the vehicle's battery mounting position is in the battery swapping area.

[0007] In the above solution, based on the vehicle information, the position of the guide relative to the battery swapping area is adjusted by the adjustment component, which can effectively guide different types of vehicles to park in the correct position quickly, so that the vehicle's battery mounting position is quickly in the battery swapping area, thereby improving the battery swapping efficiency of the battery swapping system.

[0008] According to some embodiments of this application, the guide is a non-contact guide.

[0009] In the above solution, the non-contact guide can provide non-contact guidance, thereby reducing the risk of impact between the vehicle and the battery swapping system, which could lead to damage to the battery swapping system or the vehicle.

[0010] According to some embodiments of this application, the parking lane has a vehicle entrance and a vehicle exit opposite each other along a first direction. The guide includes a light emitter for emitting light along a second direction, wherein the first direction, the second direction, and the direction of gravity are perpendicular to each other. A positioning area is provided on the vehicle, and when the light emitted by the light emitter is projected onto the positioning area, the battery mounting position is located in the battery replacement area.

[0011] In the above scheme, the light emitter emits light from the side of the vehicle towards the vehicle. It can determine the relative position of the current vehicle's battery mounting position and the battery replacement area by the relative relationship between the position of the light projected onto the vehicle and the position of the positioning area, thereby guiding the driver to drive the vehicle to the correct position and improving the battery swapping efficiency.

[0012] According to some embodiments of this application, the positioning area is located on the window of the vehicle's driver's cabin.

[0013] In the above solution, by setting the positioning area on the vehicle window, it is easy for the driver to observe. The driver can judge the relative position of the battery mounting position and the battery replacement area based on the relative positional relationship between the positioning area and the projection pattern of light, thereby efficiently guiding the driver to drive the vehicle to the correct position and improving the battery swapping efficiency.

[0014] According to some embodiments of this application, the projection pattern of the light emitted by the light emitter on a plane perpendicular to the second direction is a linear pattern.

[0015] In the above scheme, the projection pattern of the light emitted by the light emitter is linear, which helps the driver to judge the current position relationship between the vehicle and the battery replacement area through the regular projection pattern, thereby quickly adjusting the vehicle's position and improving the battery swapping efficiency.

[0016] According to some embodiments of this application, the light emitter is a laser emitter.

[0017] In the above scheme, the light emitter is set as a laser emitter, which can provide the driver with clear image information, thereby helping the driver to judge the current position relationship between the vehicle and the battery replacement area, quickly adjust the vehicle's position, and thus improve the battery swapping efficiency.

[0018] According to some embodiments of this application, the guide includes a sensor, and a positioning unit is provided on the vehicle. When the sensor senses the positioning unit, the battery mounting position is in the battery replacement area.

[0019] In the above solution, by setting the guide as a sensor and setting a positioning unit on the vehicle that matches the guide, the sensor can sense the positioning unit when the vehicle is parked in place and perform the corresponding operation to convey the parking information to the driver, thereby reducing the time the driver spends adjusting the vehicle position and improving the battery swapping efficiency.

[0020] According to some embodiments of this application, a sensor is provided on the vehicle, and when the sensor senses the guide, the battery mounting position is in the battery replacement area.

[0021] In the above solution, by setting a sensor on the vehicle and configuring the guide to match the sensor, the guide can be sensed by the sensor when the vehicle is parked and thus perform the corresponding operation to convey the parking information to the driver, thereby reducing the time the driver spends adjusting the vehicle position and improving the battery swapping efficiency.

[0022] According to some embodiments of this application, along a first direction, the parking lane has a vehicle entrance and a vehicle exit opposite to each other along the first direction, and the adjusting member is used to adjust the position of the guide along the first direction.

[0023] In the above scheme, the adjusting component can adjust the position of the guide component in the first direction according to the vehicle information, so that the guide component can guide different types of vehicles, and so that different types of vehicles can be parked smoothly and efficiently in the correct position according to the guidance of the guide component, thereby improving the battery swapping efficiency of the battery swapping system.

[0024] According to some embodiments of this application, the adjusting member includes a guide rail, a rack, and a drive motor. The guide rail extends along a first direction, the rack extends along a first direction, the guide rail and the rack are arranged side by side along the direction of gravity, the drive motor is slidably connected to the guide rail, the output end of the drive motor meshes with the rack, and the guide member is connected to the drive motor.

[0025] In the above scheme, the guide rail enables the drive motor to move stably along the first direction, thereby driving the guide to move stably along the first direction, so that the guide can effectively guide the vehicle and thus improve the battery swapping efficiency.

[0026] According to some embodiments of this application, the battery swapping system also includes a guide structure, at least a portion of which is located on the side of the parking lane opposite to the vehicle exit, for guiding vehicles into the parking lane.

[0027] In the above scheme, by setting up a guide structure, vehicles can be guided to enter the parking lane at the correct angle, reducing the risk of misalignment between the battery mounting position and the battery replacement area, and improving the battery swapping efficiency.

[0028] According to some embodiments of this application, the guide structure includes two guide rods spaced apart along a second direction. The ends of the guide rods away from the vehicle exit have guide sections. The guide sections of the two guide rods gradually decrease in the direction from the vehicle inlet to the vehicle outlet. The second direction is perpendicular to the direction from the vehicle inlet to the vehicle outlet.

[0029] In the above scheme, guided by two guide sections, the vehicle can smoothly enter the guide channel, thereby entering the parking channel at the correct angle, which reduces the risk of misalignment between the battery mounting position and the battery replacement area and helps to improve the battery swapping efficiency.

[0030] According to some embodiments of this application, the battery swapping system further includes a first display screen and a second display screen. The first display screen is disposed inside the parking lane, and the second display screen is disposed outside the parking lane and located on the side of the parking lane's vehicle exit opposite to the vehicle entrance.

[0031] In the above scheme, by setting up a first display screen in the parking lane and a second display screen at the exit side of the parking lane, the driver's field of vision can be compensated and information can be provided to the driver, thereby improving the efficiency of battery swapping.

[0032] According to some embodiments of this application, the battery swapping system also includes a voice broadcasting unit, which is installed in the parking lane for voice broadcasting.

[0033] In the above scheme, by setting up a voice broadcast unit in the parking lane to provide information to the driver through voice broadcast, the driver's field of vision can be compensated, thereby improving the efficiency of battery swapping.

[0034] The above description is only an overview of the technical solution of this application.

[0053] With the development of new energy technologies, more devices are using batteries. When these devices run out of power, they are often recharged by connecting to charging equipment, such as charging stations for electric vehicles. Compared to connecting to charging stations, battery swapping offers a faster way to replenish power. Currently, there are dedicated battery swapping systems with parking lanes. These lanes are used for parking vehicles and for battery swapping. The parking lanes also have battery swapping areas. When a battery swap is needed, the vehicle must be parked in the parking lane with its battery mount positioned in the swapping area for the swapping mechanism to perform the swap. Currently, battery swapping systems often have guides. Drivers adjust the vehicle's position based on the guides to ensure the battery mount is in the swapping area. However, because the guides are fixed within the parking lane and their position relative to the swapping area is fixed, and the relative positions of the driver's cabin and battery mount vary depending on the type of vehicle, drivers may not effectively receive the guidance information, leading to incorrect parking and affecting swapping efficiency.

[0054] In view of this, to improve the problem of low battery swapping efficiency caused by the inability to effectively guide drivers due to different vehicle types, some embodiments of this application provide a battery swapping system, which includes a parking lane and a guiding mechanism. The parking lane has a battery swapping area. The guiding mechanism is disposed within the parking lane and located on the side or top surface of the parking lane. The guiding mechanism includes a guide member and an adjusting member, with the adjusting member connected to the guide member. The adjusting member is used to adjust the position of the guide member relative to the battery swapping area according to vehicle information, so that the guide member can guide the vehicle to move until the vehicle's battery mounting position is in the battery swapping area.

[0055] In the above scheme, the adjustment component adjusts the position of the guide component relative to the battery replacement area based on the vehicle information, thereby effectively guiding different types of vehicles to park in the correct position, so that the vehicle's battery mounting position is in the battery replacement area, thereby improving the battery swapping efficiency of the battery swapping system.

[0056] The battery swapping system disclosed in this application is capable of swapping batteries for vehicles. Vehicles include, but are not limited to, passenger cars and commercial vehicles. For example, vehicle types may include sedans, urban SUVs, off-road vehicles, light trucks, heavy trucks, and tractor-trailers.

[0057] This application provides a battery swapping system in some embodiments. Please refer to Figures 1-5. Figure 1 is a schematic diagram of the battery swapping system in some embodiments of this application. Figure 2 is a schematic diagram of the battery swapping channel and vehicle in some embodiments of this application. Figure 3 is a top view of the battery swapping channel in some embodiments of this application. Figure 4 is an enlarged view of point A in Figure 3. Figure 5 is a schematic diagram of the vehicle in some embodiments of this application.

[0058] The battery swapping system 100 includes a parking lane 10 and a guiding mechanism 20. The parking lane 10 has a battery swapping area 11. The guiding mechanism 20 is disposed within the parking lane 10 and located on the side or top surface of the parking lane 10. The guiding mechanism 20 includes a guide 21 and an adjusting member 22, the adjusting member 22 being connected to the guide 21. The adjusting member 22 is used to adjust the position of the guide 21 relative to the battery swapping area 11 according to information of the vehicle 200, so that the guide 21 can guide the vehicle 200 to move until the battery mounting position of the vehicle 200 is located in the battery swapping area 11.

[0059] In some embodiments, the battery swapping system 100 may include a battery swapping station for enabling battery swapping of the vehicle 200. Exemplarily, the battery swapping station may include a main body, a battery storage device, a battery charging device, a transfer device, and a battery swapping device. The main body may be constructed from assembled and modified shipping containers, and may have a parking lane 10 for the vehicle 200 to enter and exit, where the vehicle 200 performs battery swapping. The battery storage device and the battery charging device are disposed within the main body; the battery storage device stores fully charged and depleted batteries. The battery charging device can charge the batteries stored in the battery storage device. The transfer device can be used to transfer batteries between the battery storage device and the battery swapping device. The battery swapping device is used to remove batteries from the vehicle 200 and install batteries on the vehicle 200. For example, when the vehicle 200 enters the parking lane 10 and is in the correct position, the battery swapping device moves to below the battery mounting position of the vehicle 200 and removes the depleted battery from the vehicle 200. The depleted battery can be stored in the battery storage device through the transfer device. The transfer device takes out a fully charged battery from the battery storage device and transports it to the battery swapping device. The battery swapping device mounts the fully charged battery on the battery mounting position of the vehicle 200, and the vehicle 200 completes the battery swap, drives out of the parking lane 10, and the battery swap is finished. In the battery swapping system 100, the power supply device charges the depleted battery that has been swapped out.

[0060] The parking lane 10 can be a portion of the battery swapping system 100 that provides space for parking the vehicle 200 and for battery swapping. In some embodiments, the parking lane 10 can be formed by a plurality of walls, for example, the parking lane 10 may include two side walls opposite each other and a top wall disposed at the top of the two side walls.

[0061] "Battery mounting position of vehicle 200" can be understood as the part of vehicle 200 where the battery is mounted. Please refer to Figure 5, where the battery mounting position of vehicle 200 is indicated by a dashed line and the number "204".

[0062] "Parking lane 10 has a battery swapping area 11" can be understood as an area of ​​parking lane 10 used to cooperate with vehicle 200 to allow for battery swapping of vehicle 200. In Figure 4, the location of the battery swapping area 11 is shown as a dashed line. Exemplarily, when vehicle 200 is traveling within parking lane 10 and the battery mounting position of vehicle 200 is in the battery swapping area 11, the battery swapping device can remove a depleted battery from the battery mounting position of vehicle 200 and mount a fully charged battery in the battery mounting position of vehicle 200. In some embodiments, the size of the battery swapping area 11 may be larger than the size of the battery mounting position. Referring to Figure 5, in the length direction of vehicle 200, the size of the battery swapping position is larger than the size of the battery mounting position, which can reduce the accuracy requirements for parking vehicle 200. In some embodiments, in the width direction of vehicle 200, the size of the battery swapping position may be larger than the size of the battery mounting position, which can reduce the accuracy requirements for parking vehicle 200.

[0063] The guide mechanism 20 is a mechanism for guiding the vehicle 200. "The guide mechanism 20 is located in the parking lane 10 and on the side or top of the parking lane 10" can be immediately interpreted as the guide mechanism 20 not being located on the ground. For example, the guide mechanism 20 can guide the vehicle 200 from the side or above.

[0064] The guidance mechanism 20 includes a guide member 21 and an adjustment member 22. Exemplarily, the guide member 21 can provide visual, auditory, or tactile information to the driver inside the vehicle 200 to guide the driver in controlling operations such as moving the vehicle 200 forward, forward distance, backward, and backward distance. Exemplarily, the guide member 21 may include a blocking member that extends and is positioned within the parking lane 10 when the vehicle 200 needs battery swapping. As the vehicle 200 moves into the parking lane 10, the driver can sense when the vehicle 200 contacts the blocking member, thus determining that the vehicle 200 is in the correct position and that the battery mount is in the battery replacement area 11. Alternatively, the guide member 21 may include a display screen capable of displaying information, allowing the driver to control the vehicle 200 by understanding the information on the screen and ultimately park the vehicle 200 in the correct position. Alternatively, the guide member 21 may include a light emitter, allowing the driver to control the vehicle 200 by viewing an image projected onto the cockpit through the light emitter, thereby parking the vehicle 200 in the correct position. Alternatively, the guide 21 may include a horn that broadcasts a voice message, which the driver uses to control the vehicle 200 to park it in the correct position.

[0065] Adjustment member 22 is a mechanism capable of adjusting the position of guide member 21 relative to battery replacement area 11. For example, adjustment member 22 can adjust the position of guide member 21 relative to battery replacement area 11 along the length direction of vehicle 200, or adjustment member 22 can adjust the position of guide member 21 relative to battery replacement area 11 along the height direction of vehicle 200, or adjustment member 22 can adjust the position of guide member 21 relative to battery replacement area 11 along the width direction of vehicle 200.

[0066] "The adjusting component 22 is used to adjust the position of the guide component 21 relative to the battery replacement area 11 based on the information of the vehicle 200, so that the guide component 21 can guide the vehicle 200 to move to the battery mounting position of the vehicle 200 in the battery replacement area 11." This can be understood as the guide component 21 having different guiding positions (guidance position refers to the position where the guide component can effectively provide guidance information to the vehicle) for different types of vehicles 200, and the relative position of the guide component 21 to the battery replacement area 11 is different for each type of vehicle 200. When different types of vehicles 200 enter the battery swapping system 100 for battery swapping, the adjusting component 22 can adjust the guide component 21 to the corresponding guiding position based on the information of the vehicle 200, so that the driver can effectively receive the guidance information and park the vehicle 200 in the correct position, so that the battery mounting position is in the battery replacement area 11. For example, taking different types of vehicles 200, including a first type vehicle 200 and a second type vehicle 200, when the battery swapping system 100 identifies the first type vehicle 200, the adjusting member 22 adjusts the guide member 21 to a first position, and the guide member 21 guides the vehicle 200 in the first position; when the battery swapping system 100 identifies the second type vehicle 200, the adjusting member 22 adjusts the guide member 21 to a second position, and the guide member 21 guides the vehicle 200 in the second position. For example, the guide member 21 includes a blocking member, and the battery swapping objects include the first vehicle 200 and the second vehicle 200, wherein the wheelbase of the second vehicle 200 is greater than that of the first vehicle 200. After the first vehicle 200 completes the battery swap, the battery swapping system 100 can identify the vehicle 200 information of the second vehicle 200, and therefore controls the adjusting member 22 to move the blocking member towards the exit direction, so that when the second vehicle 200 contacts the blocking member, the battery mounting position of the second vehicle 200 is in the battery replacement area 11.

[0067] In some embodiments, a camera or video camera may be installed at the entrance of the parking lane 10. The camera or video camera can acquire the license plate information of the vehicle 200, so that the battery swapping system 100 can acquire the information of the vehicle 200, thereby allowing the adjustment component 22 to adjust the position of the guide component 21 based on the information. For example, a camera is installed on the side of the entrance of the parking lane 10 to photograph the vehicle 200 about to enter the parking lane 10 and acquire the license plate information of the vehicle 200. The control device of the battery swapping system 100 obtains the vehicle 200 information corresponding to the license plate information through a cloud server or its own pre-stored data, so that the adjustment component 22 can adjust the position of the guide component 21 based on the information.

[0068] In the above scheme, based on the information of vehicle 200, the position of guide 21 relative to battery replacement area 11 is adjusted by adjusting component 22, thereby effectively guiding different types of vehicles 200 to park in the correct position, so that the battery mounting position of vehicle 200 is in battery replacement area 11, thereby improving the battery swapping efficiency of battery swapping system 100.

[0069] According to some embodiments of this application, the guide 21 is a non-contact guide 21.

[0070] In some embodiments, the "non-contact guide 21" can be one in which the guide 21 guides the vehicle 200 without contacting it and while maintaining a certain distance from it. For example, the guide 21 provides image information to the driver to guide the driving of the vehicle 200.

[0071] In the above solution, the non-contact guide 21 can perform non-contact guidance, thereby reducing the risk of impact between the vehicle 200 and the battery swapping system 100, which could lead to damage to the battery swapping system 100 or the vehicle 200.

[0072] According to some embodiments of this application, please refer to Figures 3, 4, and 5. The parking lane 10 has a vehicle entrance 12 and a vehicle exit 13 opposite each other along a first direction x. The guide 21 includes a light emitter for emitting light along a second direction y. The first direction x, the second direction y, and the gravity direction z are all perpendicular to each other. A positioning area 202 is provided on the vehicle 200. When the light emitted by the light emitter is projected onto the positioning area 202, the battery mounting position is located in the battery replacement area 11.

[0073] Please refer to Figures 2 and 3, where the light emitted by the guide 21 is indicated by the numeral "B".

[0074] In some embodiments, the first direction x may be parallel to the length direction of the vehicle 200, and the second direction y may be parallel to the width direction of the vehicle 200. The vehicle 200 may enter the parking lane 10 from the vehicle entrance 12 along the first direction x, and exit the parking lane 10 from the vehicle exit 13.

[0075] The positioning area 202 is a calibrated area on the vehicle 200. In some embodiments, the distance between the positioning area 202 and the battery mounting position of the vehicle 200 is the same for different types of vehicles 200 along the length direction of the vehicle 200. After the adjusting member 22 adjusts the position of the guide 21 according to the current vehicle 200 information, when the light emitted by the guide 21 is projected onto the positioning area 202, it indicates that the battery mounting position is in the battery replacement area 11.

[0076] The phrase "guide 21 includes a light emitter for emitting light along the second direction y" can be understood as meaning that guide 21 can be a light emitter capable of emitting light along the second direction y. In some embodiments, the light is emitted from the side of vehicle 200, and the driver can directly observe the light. For example, when the driver observes the light projected onto positioning area 202 as vehicle 200 moves, it indicates that the vehicle is parked correctly and the battery mounting position is in battery replacement area 11. In other embodiments, the light is emitted from the side of vehicle 200, and as vehicle 200 moves, when the light is projected onto positioning area 202, it triggers a corresponding operation, such as the battery swapping system 100 issuing a voice announcement or flashing lights to inform the driver that the vehicle is parked correctly and the battery mounting position is in battery replacement area 11. In these embodiments, positioning area 202 may be equipped with a photoelectric receiving sensor, which sends a corresponding signal to the control device in battery swapping system 100 to implement voice announcements or flashing lights to prompt the driver to park correctly. In some embodiments, the positioning area 202 may be provided with a reflective unit. When light is projected onto the positioning area 202, the reflective unit can reflect the light. The battery swapping system 100 is provided with a photoelectric receiving sensor. After the photoelectric receiving sensor receives the reflected light, it sends a corresponding signal to the control device in the battery swapping system 100 to realize voice broadcast or flashing lights and other operations to prompt the driver to park in place.

[0077] For example, the light emitter can emit light of colors including, but not limited to, red, blue, green, etc. In some embodiments, the light emitter can be a laser emitter, and the light emitted by the laser emitter can be projected onto the window 201 of the driver's cabin, allowing the driver to adjust the position of the vehicle 200 according to the light pattern on the window 201. For example, the positioning area 202 includes a marking pattern (e.g., a square pattern, a circular pattern, or a pattern formed by multiple line segments) set on the window 201. When the laser emitted by the laser emitter is projected onto the window 201, the driver drives the vehicle 200 so that the pattern projected onto the window 201 is located in the area where the marking pattern is located (e.g., the pattern projected onto the window 201 is located in a square pattern, a circular pattern, or between multiple line segments). In this state, the battery mounting position is in the battery replacement area 11.

[0078] In the above scheme, the light emitter vehicle 200 emits light from the side towards the vehicle 200. The relative position of the battery mounting position of the vehicle 200 and the battery replacement area 11 can be determined by the relative relationship between the position of the light projected onto the vehicle 200 and the position of the positioning area 202. This guides the driver to drive the vehicle 200 to the correct position, thereby improving the battery swapping efficiency.

[0079] According to some embodiments of this application, please refer to FIG5, the positioning area 202 is disposed on the window 201 of the driver's cabin of the vehicle 200.

[0080] In some embodiments, "the positioning area 202 is disposed on the window 201 of the driver's cabin of the vehicle 200" can be understood as the light emitted by the light emitter being projected onto the window 201 of the driver's cabin of the vehicle 200, and being able to cooperate with the positioning area 202 located on the window 201 to guide the vehicle 200 to the correct position. For example, the light emitted by the light emitter is used to provide image information to the driver to guide the driver in controlling the vehicle 200. The positioning area 202 can be a marking pattern (e.g., a square pattern, a circular pattern, or a pattern formed by multiple line segments) disposed on the window 201. By comparing the projected light pattern with the marking pattern on the window 201, the driver can control the vehicle 200 to drive, ultimately parking the vehicle 200 in the correct position.

[0081] For example, referring to Figure 5, in some embodiments, the positioning area 202 may include three marking lines 2020. The three marking lines 2020 may be spaced apart along the first direction x. The middle line is the baseline (the distance between the baseline and the battery mounting position of the vehicle 200 is the same for different types of vehicles 200), and the two marking lines 2020 on both sides are the critical lines. The light emitter emits light in the second direction y. As the vehicle 200 moves into the parking lane 10, the light can be projected onto the window 201 of the driver's cabin of the vehicle 200. When the driver observes that the projected pattern of the light falls on the two critical lines, he realizes that the battery mounting position is in the battery replacement area 11, which is within the battery swapping range of the battery swapping system 100, and he can stop to swap the battery. When the driver observes that the projected pattern of the light falls on the baseline, it indicates that the vehicle 200 is in a better position, and he realizes that the overlap between the battery mounting position and the battery replacement area 11 is better, and the vehicle 200 is accurately within the battery swapping range of the battery swapping system 100, and he can stop to swap the battery.

[0082] In the above scheme, by setting the positioning area 202 on the window 201, it is easy for the driver to observe and the driver can judge the relative position of the battery mounting position of the current vehicle 200 and the battery replacement area 11 based on the relative positional relationship between the positioning area 202 and the projection pattern of light, thereby efficiently guiding the driver to drive the vehicle 200 to the correct position and improving the battery swapping efficiency.

[0083] In other embodiments, the positioning unit 203 may be disposed in other parts of the vehicle 200. For example, the positioning area 202 may include a photoelectric receiving sensor disposed on the body of the vehicle 200. When the light emitted by the light emitter is received by the photoelectric receiving sensor, the photoelectric receiving sensor sends a corresponding signal to the control device in the battery swapping system 100, thereby performing operations such as voice broadcasting or flashing lights to prompt the driver to park in place.

[0084] According to some embodiments of this application, the projection pattern of the light emitted by the light emitter on a plane perpendicular to the second direction y is a linear pattern.

[0085] In some embodiments, the light emitted by the light emitter is a linear light beam, so that the projected pattern seen by the driver is a linear pattern. In some embodiments, the light emitter can emit a linear beam through a slit light source, a beam shaper, a physical block, a laser, or the like.

[0086] For example, the pattern of light emitted by the light emitter projected onto the window 201 is a linear pattern perpendicular to the length direction of the vehicle 200. Referring to Figure 5, three marker lines 2020 are provided on the window 201 at intervals along the length direction of the vehicle 200. The length direction of each marker line 2020 is perpendicular to the length direction of the vehicle 200. The linear pattern of light emitted by the light emitter projected onto the window 201 can be parallel to the marker lines 2020. By comparing the positional relationship between the linear pattern and the marker lines 2020, the driver can control the vehicle 200 to move forward or backward, thereby quickly parking in the correct position to achieve battery swapping.

[0087] In the above scheme, the projection pattern of the light emitted by the light emitter is linear, which helps the driver to judge the positional relationship between the current vehicle 200 and the battery replacement area 11 through the regular projection pattern, thereby quickly adjusting the position of the vehicle 200 and improving the battery swapping efficiency.

[0088] According to some embodiments of this application, the light emitter is a laser emitter.

[0089] In some embodiments, the laser emitter can emit a very narrow linear beam of light, and the light emitted by the laser emitter has a high degree of monochromaticity and directionality. The width and intensity of the light can be controlled by adjusting the output of the laser emitter.

[0090] In some embodiments, the laser emitted by the laser emitter can be other colors such as red, blue, or green. For example, the laser emitter can emit red laser light. The laser emitter can project a red linear pattern onto the vehicle window 201, thereby facilitating the driver to adjust the position of the vehicle 200 based on the relative position of the linear pattern and the positioning area 202.

[0091] In the above scheme, the light emitter is set as a laser emitter, which can provide the driver with clear image information, thereby helping the driver to judge the positional relationship between the current vehicle 200 and the battery replacement area 11, quickly adjust the position of the vehicle 200, and thus improve the battery swapping efficiency.

[0092] Please refer to Figure 6, which is a schematic diagram of the battery swapping system 100 and the vehicle 200 in some other embodiments of this application.

[0093] The guide 21 includes a sensor, and a positioning part 203 is provided on the vehicle 200. In some embodiments, the distance between the positioning part 203 and the battery mounting position of the vehicle 200 is the same for different types of vehicles 200 along the length direction of the vehicle 200. After the adjusting member 22 adjusts the position of the guide 21 according to the current vehicle 200 information, when the sensor senses the positioning part 203, the battery mounting position is in the battery replacement area 11.

[0094] A sensor is a detection device that can sense certain physical quantities (such as temperature, pressure, humidity, light intensity, sound, displacement, etc.) of the external environment or objects, and convert these physical quantities into electrical signals or other forms of signal output for subsequent measurement, recording or control.

[0095] In some embodiments, the guide 21 includes a sensor that can cooperate with the positioning part 203 on the vehicle 200 to guide the driver to adjust the position of the vehicle 200 so that the battery mounting position is in the battery replacement area 11, thereby realizing battery swapping. For example, by adjusting the position of the vehicle 200, the driver enables the sensor to sense the positioning part 203 on the vehicle 200, so that the sensor can provide a corresponding signal to the control device of the battery swapping system 100. The control device can prompt the driver that the vehicle 200 is currently parked in place through a display screen or a voice broadcast unit 50.

[0096] In some embodiments, the guide 21 may include a photoelectric sensor, a displacement sensor, etc. For example, the guide 21 may include a proximity switch, which may include a magnetic proximity switch, and the positioning part 203 may be a magnetic object that cooperates with the proximity switch. Alternatively, in some embodiments, the guide 21 includes a receiver, and the positioning part 203 on the vehicle 200 is a transmitter; when the receiver receives a signal emitted by the transmitter, the battery mounting position is in the battery replacement area 11.

[0097] In the above solution, by setting the guide 21 as a sensor and setting a positioning part 203 that matches the guide 21 on the vehicle 200, the sensor can sense the positioning part 203 when the vehicle 200 is parked in place and perform the corresponding operation, so as to convey the parking information to the driver, thereby reducing the time for the driver to adjust the position of the vehicle 200 and improving the battery swapping efficiency.

[0098] According to some embodiments of this application, a sensor is provided on the vehicle 200, and when the sensor senses the guide 21, the battery mounting position is in the battery replacement area 11.

[0099] In some embodiments, the distance between the sensors of different types of vehicles 200 and the battery mounting position of the vehicle 200 is the same along the length direction of the vehicle 200. After the adjustment member 22 adjusts the position of the guide 21 into place according to the current vehicle 200 information, when the sensor senses the guide 21, the battery mounting position is in the battery replacement area 11.

[0100] For example, the driver adjusts the position of the vehicle 200 so that the sensor can detect the guide 21, which has been adjusted into place by the adjuster 22. When the sensor detects the guide 21, it can provide a corresponding signal to the control device of the battery swapping system 100. The control device can then prompt the driver that the vehicle 200 is now parked in place via a display screen or a voice broadcast unit 50. Alternatively, when the sensor detects the guide 21, it can provide a corresponding signal to the controller of the vehicle 200. The controller of the vehicle 200 can then prompt the driver that the vehicle 200 is now parked in place via the vehicle infotainment module.

[0101] In some embodiments, the sensor may include a photoelectric sensor, a displacement sensor, etc. For example, the sensor may include a proximity switch, which may include a magnetic proximity switch, and the positioning element may be a magnetic object associated with the proximity switch.

[0102] In the above solution, by setting a sensor on the vehicle 200 and setting the guide 21 to match the sensor, when the vehicle 200 is parked in place, the guide 21 can be sensed by the sensor and perform the corresponding operation to convey the parking information to the driver, thereby reducing the time the driver spends adjusting the position of the vehicle 200 and improving the battery swapping efficiency.

[0103] According to some embodiments of this application, please refer to FIG3, along the first direction x, the parking lane 10 has a vehicle entrance 12 and a vehicle exit 13 opposite to each other along the first direction x, and the adjustment member 22 is used to adjust the position of the guide member 21 along the first direction x.

[0104] In some embodiments, the first direction x can be parallel to the direction from the vehicle entrance 12 to the vehicle exit 13 of the parking lane 10, or it can be parallel to the driving direction of the vehicle 200, the length direction of the vehicle 200, or the axial direction of the vehicle 200. For example, the vehicle 200 can travel along the first direction x, enter the parking lane 10 through the vehicle entrance 12, and exit the parking lane 10 through the vehicle exit 13.

[0105] "Adjusting member 22 is used to adjust the position of guide member 21 along the first direction x" can be understood as follows: when dealing with vehicles 200 with different wheelbases, adjusting member 22 can adjust the position of guide member 21 relative to battery replacement area 11 in the axial direction of vehicle 200.

[0106] For example, the distance between the driver's cabin and the battery mount of a vehicle 200 with different wheelbases is different. For instance, the distance between the driver's cabin and the battery mount of a vehicle 200 with a larger wheelbase is greater. Therefore, when a vehicle 200 with a larger wheelbase needs to swap batteries through the battery swapping system 100, the adjusting member 22 will adjust the position of the guide member 21 so that the guide member 21 moves along the first direction x and is closer to the vehicle exit 13, thereby effectively guiding the driver in the driver's cabin.

[0107] In some embodiments, the adjustment member 22 may include a mechanism capable of outputting linear motion along a first direction x. For example, the adjustment member 22 may include a single-axis manipulator, a linear motor, a cylinder, or other mechanical combination capable of outputting linear motion.

[0108] In the above scheme, the adjusting component 22 can adjust the position of the guiding component 21 in the first direction x according to the information of the vehicle 200, so that the guiding component 21 can guide different types of vehicles 200, so that different types of vehicles 200 can be smoothly and efficiently parked in the correct position according to the guidance of the guiding component, thereby improving the battery swapping efficiency of the battery swapping system 100.

[0109] According to some embodiments of this application, please refer to Figures 7 and 8. Figure 7 is a schematic diagram of the guide mechanism 20 and the parking lane 10 in some embodiments of this application, and Figure 8 is a schematic diagram of the adjusting member 22 and the guide member 21 in some embodiments of this application. The adjusting member 22 includes a guide rail 220, a rack 221, and a drive motor 222. The guide rail 220 extends along a first direction x, and the rack 221 extends along the first direction x. The guide rail 220 and the rack 221 are arranged side by side along the gravity direction z. The drive motor 222 is slidably connected to the guide rail 220, and the output end of the drive motor 222 meshes with the rack 221. The guide member 21 is connected to the drive motor 222.

[0110] In some embodiments, the adjusting member 22 may be disposed on the side of the parking lane 10. The adjusting member 22 includes a guide rail 220, a rack 221, and a drive motor 222. The guide rail 220 is connected to the side of the parking lane 10 and extends along a first direction x. The connection between the guide rail 220 and the side includes, but is not limited to, bonding, welding, or threaded connection. The rack 221 extends along the first direction x, and the rack 221 and the guide rail 220 are arranged side by side in the gravity direction z. The adjusting member 21 is disposed on the drive motor 222. The drive motor 222 can slide with the guide rail 220. Exemplarily, the housing of the drive motor 222 is formed in a groove that mates with the guide rail 220, the guide rail 220 is disposed in the groove, and the drive motor 222 is capable of reciprocating along the guide rail 220 in the first direction x. The output end of the drive motor 222 meshes with the rack 221. Exemplarily, the output shaft of the drive motor 222 is provided with a gear, and the gear meshes with the rack 221. When the battery swapping system 100 recognizes the information of the vehicle 200, the battery swapping system 100 can control the drive motor 222 to rotate forward or reverse according to the information of the vehicle 200, thereby driving the guide 21 to move in the first direction x.

[0111] In the above scheme, the guide rail 220 guides the drive motor 222 to move stably along the first direction x, which in turn drives the guide member 21 to move stably along the first direction x, so that the guide member 21 can effectively guide the vehicle 200, thereby improving the battery swapping efficiency.

[0112] According to some embodiments of this application, please refer to FIG3, the battery swapping system 100 further includes a guide structure 30, at least a portion of which is located on the side of the vehicle entrance 12 of the parking lane 10 opposite to the vehicle exit 13, for guiding the vehicle 200 into the parking lane 10.

[0113] The guide structure 30 is a structural component that guides the driving direction of the vehicle 200. For example, the guide structure 30 includes a guide rod 31, a guide groove, etc.

[0114] "At least a portion of the guide structure 30 is located on the side of the vehicle entrance 12 of the parking lane 10 away from the vehicle exit 13" can be understood as the guide structure 30 being located at the vehicle entrance 12 of the parking lane 10. The guide structure 30 may be partially located inside the parking lane 10 and another portion located outside the parking lane 10, or the guide structure 30 may be entirely located outside the parking lane 10.

[0115] In the above scheme, by setting the guide structure 30, the vehicle 200 can be guided to enter the parking lane 10 at the correct angle, reducing the risk of misalignment between the battery mounting position and the battery replacement area 11, and improving the battery swapping efficiency.

[0116] According to some embodiments of this application, the guide structure 30 includes two guide rods 31 spaced apart along a second direction y. The end of the guide rod 31 away from the vehicle outlet 13 has a guide section 310. Along the direction from the vehicle inlet 12 to the vehicle outlet 13, the distance between the guide sections 310 of the two guide rods 31 gradually decreases. The second direction y is perpendicular to the direction from the vehicle inlet 12 to the vehicle outlet 13.

[0117] In some embodiments, guide rods 31 are arranged in pairs, each pair including two guide rods 31 spaced apart along a second direction y, the two guide rods 31 jointly defining a guide channel for the vehicle 200 to enter. Along the direction from the vehicle inlet 12 to the vehicle outlet 13, the centerline of the guide channel may be parallel to or even collinear with the centerline of the parking lane 10. The guide rods 31 are used to contact the wheels of the vehicle 200, limiting the tilt angle of the vehicle 200, thereby ensuring that the driving direction of the vehicle 200 is parallel to the direction from the vehicle inlet 12 to the vehicle outlet 13.

[0118] The guide section 310 of the guide rod 31 is outwardly expanding so that the inlet of the guide channel can be widened, which facilitates the vehicle 200 to enter the guide channel.

[0119] In some embodiments, the guide structure 30 may include two pairs of guide rods 31, wherein one pair of guide rods 31 is disposed on the entrance side of the parking lane 10, for example, partly located inside the parking lane 10 and the other part located outside the parking lane 10; the other part may be disposed on the exit side of the parking lane 10, for example, partly located inside the parking lane 10 and the other part located outside the parking lane 10.

[0120] In the above scheme, under the guidance of the two guide sections 310, the vehicle 200 can smoothly enter the guide channel, thereby entering the parking channel 10 at the correct angle, which reduces the risk of misalignment between the battery mounting position and the battery replacement area 11 and is conducive to improving the battery swapping efficiency.

[0121] According to some embodiments of this application, the battery swapping system 100 further includes a first display screen 41 and a second display screen 42. The first display screen 41 is disposed inside the parking lane 10, and the second display screen 42 is disposed outside the parking lane 10 and located on the side of the parking lane 10 opposite to the vehicle entrance 12 at the vehicle exit 13.

[0122] The display screen is used to provide visual information to the driver. For example, the display screen is connected to the control device of the battery swapping system 100, and can display the current battery swapping status, such as "Battery swapping in progress" or "Battery swapping progress at x%". The display screen can be an LED display screen, an LCD display screen, or other types of display screen.

[0123] In some embodiments, the battery swapping system 100 may include two displays, namely a first display 41 and a second display 42. The first display 41 may be disposed within the parking lane 10, for example, it may be disposed on the side wall of the parking lane 10. The second display 42 may be disposed on the exit side of the parking lane 10. The second display 42 can be used to compensate for the driver's field of vision. For example, in a vehicle 200 with a large wheelbase, the driver's cabin may be outside the parking lane 10 during battery swapping, and the driver may not be able to see the first display 41. In this case, the second display 42 can provide image information to the driver.

[0124] In some embodiments, the second display screen 42 may be mounted on the ground on the side of the parking lane 10 opposite to the vehicle entrance 12 via a bracket.

[0125] In the above scheme, by setting up a first display screen 41 in the parking lane 10 and a second display screen 42 on the exit side of the parking lane 10, the driver's field of vision can be compensated and information can be provided to the driver, thereby improving the battery swapping efficiency.

[0126] According to some embodiments of this application, the battery swapping system 100 also includes a voice broadcasting unit 50, which is disposed in the parking lane 10 for voice broadcasting.

[0127] The voice broadcast unit 50 is used to provide voice information to the driver. For example, the voice broadcast unit 50 is connected to the control device of the battery swapping system 100, and the voice information broadcast by the voice broadcast unit 50 may include the battery swapping status, such as "battery swapping in progress" or "battery swapping progress is x%".

[0128] In some embodiments, the voice broadcasting unit 50 may include a speaker. In some embodiments, the voice broadcasting unit 50 may be disposed on the top or side of the parking lane 10.

[0129] In the above scheme, by setting up a voice broadcast unit 50 in the parking lane 10 to provide information to the driver in the form of voice broadcast, the driver's field of vision can be compensated, thereby improving the battery swapping efficiency.

[0130] This application provides a battery swapping system 100 according to some embodiments, as shown in Figures 1-8. The battery swapping system 100 includes a parking lane 10 and a guide mechanism 20. The parking lane 10 has a battery replacement area 11. Along a first direction x, the parking lane 10 has a vehicle entrance 12 and a vehicle exit 13 opposite to each other, with the battery replacement area 11 located between the vehicle entrance 12 and the vehicle exit 13. At the vehicle entrance 12, a pair of guide rods 31 are provided, with a portion of the guide rods 31 located inside the parking lane 10 and another portion located outside the parking lane 10. The guide rods 31 are used to limit the tilt angle of a vehicle 200 entering the parking lane 10, allowing the vehicle 200 to enter the parking lane 10 along the first direction x. Referring to Figures 2, 3, and 7, the battery swapping system 100 also includes a first display screen 41 and a second display screen 42. The first display screen 41 is disposed within the parking lane 10 and located on the side of the parking lane 10; exemplaryly, the first display screen 41 may be located above the guide mechanism 21. The second display screen 42 is located outside the parking lane 10 and on the side of the parking lane 10's vehicle exit 13 opposite to the vehicle entrance 12.

[0131] The guiding mechanism 20 is disposed within the parking lane 10 and located on the side of the parking lane 10. The guiding mechanism 20 includes a guide member 21 and an adjusting member 22, with the adjusting member 22 connected to the guide member 21. The adjusting member 22 is used to adjust the position of the guide member 21 relative to the battery replacement area 11 along a first direction x according to information of the vehicle 200, so that the guide member 21 can guide the vehicle 200 to move until the battery mounting position of the vehicle 200 is located in the battery replacement area 11.

[0132] The guide 21 includes a laser emitter capable of emitting a linear laser along a second direction y, with the first direction x, the second direction y, and the gravitational direction z all perpendicular to each other. A positioning area 202 is provided on the window 201 of the driver's cabin of the vehicle 200. The positioning area 202 includes three marking lines 2020, which can be spaced apart along the first direction x. The middle line serves as a baseline, and the distance between the baseline and the battery mounting position of the vehicle 200 is the same for vehicles with different wheelbases. The two marking lines 2020 on either side serve as critical lines.

[0133] Before vehicle 200 enters parking lane 10, battery swapping system 100 acquires information about vehicle 200. Adjustment component 22 adjusts the position of guide component 21 relative to battery swapping area 11 along the first direction x based on this information. As vehicle 200 enters parking lane 10, the driver can observe a laser projection pattern on window 201. When the projection pattern is between two critical lines, it indicates that the battery mount of vehicle 200 is in battery swapping area 11, and vehicle 200 is in the correct position for battery swapping.

[0134] In the above scheme, based on the information of vehicle 200, the position of guide 21 relative to battery replacement area 11 is adjusted by adjusting component 22, which can effectively guide different types of vehicles 200 to park in the correct position quickly, so that the battery mounting position of vehicle 200 is quickly in battery replacement area 11, thereby improving the battery swapping efficiency of battery swapping system 100.

[0135] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
