Description

Technical Field

[0001] The present application relates to the technical field of vehicle battery replacement, and in particular to a vehicle battery replacement auxiliary positioning device and method. Background Art

[0002] At present, for electric vehicles that are in continuous operation, it is usually necessary to replace the vehicle's battery through a battery replacement device. At present, commercial vehicles, especially large mining trucks, mainly use side-swap battery replacement equipment for battery replacement, that is, the battery replacement equipment replaces the battery of the vehicle on one side of the vehicle.

[0003] Since the location of the battery swapping equipment is fixed, the current battery swapping is mainly performed by the driver based on his or her personal driving judgment. The driver drives the vehicle to the battery swapping equipment and then starts the battery swapping equipment to swap the battery of the vehicle.

[0004] However, due to the long body of the truck and the different driving experience of each driver, the parking position of the vehicle during battery replacement often does not meet the requirements of the battery replacement equipment, resulting in the battery replacement equipment being unable to detect the vehicle or the vehicle colliding with the battery replacement equipment, and the vehicle being parked at an angle, making it impossible to clamp the battery when replacing the battery, or causing damage to the equipment and battery due to uneven force. Therefore, it can be seen that the existing technology not only cannot ensure the smooth progress of battery replacement, but also easily causes safety problems. Summary of the invention

[0032] When the distance measured by the first group of limit laser sensors is less than the maximum measurement value, a prompt message is sent to the speaker indicating that the distance between the vehicle and the electrical device is too close; wherein the first group of limit laser sensors are the limit laser sensors that are closer to the battery exchange device;

[0033] When the distance measured by the second group of limit laser sensors is less than the maximum measurement value, a prompt message is sent to the speaker that the vehicle position is too far away from the electrical equipment; wherein, the second group of limit laser sensors are the limit laser sensors that are farther away from the battery exchange equipment.

[0036] When the distance measured by the first group of limit laser sensors is smaller than the distance measured by the second group of limit laser sensors, a prompt message is sent to the speaker indicating that the body of the vehicle to be replaced is tilted to the right.

The two sets of limit laser sensors are respectively arranged on both sides of the battery swap channel, and are used to measure the distance between them and objects in the battery swap channel in real time.

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] In this application, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0055] The present application embodiment provides a vehicle battery replacement auxiliary positioning device, such as Figure 1 As shown, including:

[0056] Two sets of limit laser sensors and voice announcer.

[0057] Two sets of limit laser sensors are respectively arranged on both sides of the battery exchange channel to measure the distance between them and objects in the battery exchange channel in real time.

[0058] Among them, the distance between the two groups of limiting laser sensors is equal to the width of the vehicle to be replaced, and the distance between a group of limiting laser sensors closer to the battery replacement equipment and the straight line where the battery replacement equipment is located is the set vehicle battery replacement distance, that is, the laser emitted by the limiting laser sensor is level with the battery replacement equipment, and is the set vehicle battery replacement distance.

[0059] Optionally, the position-limiting laser sensor is usually located at the exit area of ​​the battery-swapping channel and faces the entrance of the battery-swapping channel, so that the distance from the vehicle to the vehicle can be continuously measured when the vehicle enters the battery-swapping channel, so that the vehicle position can be corrected when the vehicle enters the battery-swapping channel. Of course, it can also be set at the entrance of the Huaduo channel and face the exit of the battery-swapping channel, and measurement can also be performed.

[0060] The voice announcer is connected to two sets of position-limiting laser sensors respectively, which can be wired or wireless, and its installation location can be selected according to needs, as long as the driver can clearly hear the voice prompt. It is used to receive the distance measured by the two sets of position-limiting laser sensors in real time, and based on the distance measured by the two sets of position-limiting laser sensors, it corrects the vehicle position of the battery-swapped vehicle with voice prompts.

[0061] It should be noted that since the spacing between the two sets of limit laser sensors is equal to the width of the vehicle to be replaced, and the distance between the set of limit laser sensors that is closer to the battery replacement equipment and the straight line where the battery replacement equipment is located is the set vehicle battery replacement distance, when the distance between the vehicle and the battery replacement equipment is in line with the set vehicle battery replacement distance, and there is no deviation in the vehicle body, both sets of limit laser sensors can measure the distance to the vehicle, and the measured distance is consistent. When the distance between the vehicle and the battery replacement equipment does not meet the set vehicle battery replacement distance, there will be a set of limit laser sensors that cannot measure. When the vehicle body is deflected, the measured distance will be different due to the different positions of the vehicle irradiated by the laser. Therefore, the voice announcer can judge whether the distance between the vehicle and the battery replacement equipment meets the vehicle battery replacement distance based on the distance measured by the limit laser sensor, and there is no offset, and when the distance between the vehicle and the battery replacement equipment does not meet the vehicle battery replacement distance, or there is an offset, voice playback is performed to prompt the driver to make corrections in time.

[0062] Specifically, the distances measured by the two sets of limit laser sensors can be compared. Figure 1 As shown in the figure, when the vehicle body is not tilted and the distance to the battery swapping device is consistent with the vehicle battery swapping distance, the distances measured by the two sets of limit laser sensors are consistent. When the distances measured by the two sets of limit laser sensors are inconsistent, there are two situations. One is: the vehicle is too close or too far from the battery swapping device, resulting in one set of limit laser sensors not measuring the vehicle, and its measurement value is relatively large. For example, Figure 2 As shown in the figure, the vehicle is too close to the battery swapping equipment, resulting in the left limit laser sensor not measuring the vehicle. Another situation is: the vehicle body is skewed, causing the two sets of limit laser sensors to measure the front and rear ends of the vehicle respectively, resulting in inconsistent distances measured by the two sets of limit laser sensors. For example, Figure 3 As shown, since the vehicle body tilts to the left, the left limit laser sensor measures the front part of the vehicle, while the right limit laser sensor measures the rear part of the vehicle, so the distance measured by the left limit laser sensor is smaller than the distance measured by the right limit laser sensor.

[0063] Therefore, when the distances measured by the two sets of limit laser sensors are inconsistent, it is further determined whether the distances measured by the two sets of limit laser sensors are both less than the maximum measurement value. Among them, the maximum measurement value is the distance measured by the limit laser sensor when there is no object in the battery exchange channel, that is, when the limit laser sensor does not measure the vehicle in the battery exchange channel, the default is the maximum measurement value. Therefore, if it is determined that only one set of limit laser sensors measures a distance less than the maximum measurement value, that is, one set of limit laser sensors measures the vehicle, then it means that the current vehicle body is not skewed, but the measured distance with the battery exchange equipment does not meet the requirements, resulting in a set of limit laser sensors being unable to measure the vehicle. Therefore, at this time, the voice prompt indicates that the distance between the vehicle to be exchanged and the battery exchange equipment does not meet the distance requirements. If it is determined that the distances measured by the two sets of limit laser sensors are both less than the maximum measurement value, it means that the vehicle body is skewed at this time, and the voice prompt indicates that the vehicle body to be exchanged is skewed.

[0064] Optionally, in order to allow the vehicle to adjust its position to roughly meet the requirements before entering the indicated navigation area measured by the limit laser sensor, the driver can adjust the vehicle position according to the instructions given by the navigation device before the vehicle enters the indicated navigation area. In addition, driving lane lines can be set on the battery exchange channel.

[0065] Optionally, considering that a single limiting laser sensor has limited ability to limit the position of the vehicle, in another embodiment of the present application, Figure 4 As shown, each set of limit laser sensors includes: two limit laser sensors.

[0066] In addition, the spacing between the two position-limiting laser sensors is set based on the tire width of the vehicle to be replaced, and is usually set to one tire width of the vehicle to be replaced. In addition, the heights of the two position-limiting laser sensors are both lower than the chassis height of the vehicle to be replaced, so that the position of the vehicle can be limited by limiting the position of the vehicle's tires.

[0067] Specific as Figure 5As shown, the tires of the vehicle need to be exactly in the area between the two limit laser sensors. When the parking distance of the vehicle does not meet the requirements, it will exceed the area, and a prompt can be given at this time. If the distances between the two sets of limit laser sensors are inconsistent, it means that the vehicle body is skewed.

[0068] Optionally, considering that the sizes of vehicles that may need battery replacement are different, the vehicle battery replacement auxiliary positioning device in another embodiment of the present application further includes:

[0069] Vehicle width detector and moving device.

[0070] Among them, a group of limit laser sensors that are far away from the battery swapping equipment are set on a mobile device to enable the movement of the group of limit laser sensors. Since the group of battery swapping equipment that is closer to the battery swapping equipment is farther away, it limits the distance between the vehicle and the battery swapping equipment to the set vehicle battery swapping distance, so it cannot be moved.

[0071] The vehicle width detector is arranged at the entrance of the battery swap channel and connected to the mobile device. It is used to detect the width of the vehicle to be swapped when the vehicle to be swapped enters the battery swap channel, and send the detected width of the vehicle to be swapped to the mobile device for movement, so that the mobile device can adjust the distance between the two sets of limit laser sensors to be consistent with the width of the vehicle to be swapped.

[0072] Optionally, in an embodiment of the present application, considering that the vehicle needs to exit the battery swap channel from between the two sets of limiting laser sensors after the battery swap is completed, in an embodiment of the present application, the mobile device is also respectively connected to the two sets of limiting laser sensors to receive the distance measured by the limiting laser sensors in real time, and when the distance measured by any set of limiting laser sensors is less than the preset minimum distance, the distance between the two sets of limiting laser sensors will be adjusted to the maximum by moving, so as to allow the vehicle to pass and avoid collision.

[0073] Of course, the exit of the battery swap channel can also be set on the side of the battery swap channel, and the vehicle can exit the battery swap channel by turning, so there is no need to move the limit laser sensor.

[0074] Optionally, in order to save energy and extend the life of the device, the vehicle battery replacement auxiliary positioning device in another embodiment of the present application further includes:

[0075] A Bluetooth device is installed at the entrance area of ​​the battery exchange channel.

[0076] The Bluetooth device is respectively connected to the voice announcer and two sets of limit laser sensors, and is used to start the voice announcer and the two sets of limit laser sensors when connected to the vehicle to be replaced, and to turn off the voice announcer and the two sets of limit laser sensors when disconnected from the vehicle to be replaced.

[0077] Among them, when the vehicle to be replaced enters the battery replacement channel, the Bluetooth device is connected to the vehicle to be replaced, and when the vehicle to be replaced leaves the battery replacement channel, the connection with the vehicle to be replaced is disconnected, so that the device can work in time when a vehicle needs to replace the battery, and can be turned off in time after the vehicle completes the battery replacement.

[0078] The embodiment of the present application provides a vehicle battery swap auxiliary positioning device, which includes two sets of limit laser sensors and a voice announcer. The two sets of limit laser sensors are respectively arranged on both sides of the battery swap channel, and are used to measure the distance between them and objects in the battery swap channel in real time. Since the spacing between the two groups of the limiting laser sensors is equal to the width of the vehicle to be replaced, and the distance between the group of limiting laser sensors that is closer to the battery replacement equipment and the straight line where the battery replacement equipment is located is the set vehicle battery replacement distance, when the distance between the vehicle and the battery replacement equipment is the battery replacement distance and there is no deviation in the vehicle body, the distances measured by the two groups of limiting laser sensors are consistent. When the distance between the vehicle and the battery replacement equipment is not the battery replacement distance or there is a deviation in the vehicle body, the distances measured by the two groups of limiting laser sensors are inconsistent. Therefore, in the embodiment of the present application, the voice announcer is respectively connected to the two groups of the limiting laser sensors to receive the distances measured by the two groups of the limiting laser sensors in real time, and based on the distances measured by the two groups of the limiting laser sensors, a corrective voice prompt is given to the vehicle position of the vehicle to be replaced, so that the driver can adjust the vehicle position according to the corrective voice prompt so that the distance between the vehicle and the battery replacement equipment is consistent with the vehicle battery replacement distance and there is no deviation in the vehicle body, thereby ensuring the order of battery replacement and avoiding safety problems.

[0079] Another embodiment of the present application provides a vehicle battery replacement auxiliary positioning method, which is applied to the vehicle battery replacement auxiliary positioning device provided in the above embodiment. Therefore, the vehicle battery replacement auxiliary positioning device includes two sets of limit laser sensors and a voice announcer. Figure 6 As shown, the vehicle battery replacement auxiliary positioning method provided in the embodiment of the present application includes the following steps:

[0080] S601, two sets of limit laser sensors measure the distance between them and objects in the battery exchange channel in real time.

[0081] Among them, two groups of limit laser sensors are respectively set on both sides of the battery swap channel. The distance between the two groups of limit laser sensors is equal to the width of the vehicle to be swapped, and the distance between the group of limit laser sensors closer to the battery swap equipment and the straight line where the battery swap equipment is located is the set vehicle battery swap distance.

[0082] Specifically, since the vehicle is driving into the battery swap channel for battery swapping, the two sets of limit laser sensors actually collect real-time measurements of the distance between the vehicle and the vehicle to be swapped.

[0083] In order to make the position-limiting laser sensor and the voice announcer work only when a vehicle is changing batteries, in another embodiment of the present application, the vehicle battery-changing auxiliary positioning device also includes a Bluetooth device connected to the voice announcer and the two sets of position-limiting laser sensors respectively. Accordingly, in the embodiment of the present application, before executing step S601, it also includes:

[0084] The Bluetooth device connects to the vehicle entering the battery swap channel in real time.

[0085] When the Bluetooth device is connected to the vehicle waiting to be replaced that enters the battery replacement channel, it activates the voice announcer and two sets of limit laser sensors.

[0086] When the Bluetooth device is disconnected from the vehicle to be replaced, the voice announcer and two sets of limit laser sensors are turned off. When the vehicle to be replaced leaves the replacement channel, the connection with the vehicle to be replaced is disconnected.

[0087] Optionally, considering the need to replace batteries for vehicles of different sizes, in another embodiment of the present application, the vehicle battery replacement auxiliary positioning device also includes: a vehicle width detector and a moving device.

[0088] Among them, a group of limit laser sensors far away from the battery exchange equipment is set on the mobile device. The vehicle width detector is set at the entrance of the battery exchange channel and connected to the mobile device.

[0089] Accordingly, in the embodiment of the present application, before executing step S601, the following may be further included:

[0090] The vehicle width detector detects the width of the vehicle to be replaced that enters the battery replacement channel, and sends the detected width of the vehicle to be replaced to the mobile device for movement.

[0091] The mobile device moves to adjust the distance between the two sets of limit laser sensors to be consistent with the width of the vehicle to be replaced.

[0092] S602. The voice announcer provides a corrective voice prompt for the vehicle position of the vehicle to be battery swapped based on the distance measured by the two sets of limit laser sensors.

[0093] Optionally, in another embodiment of the present application, a specific implementation of step S602 is as follows: Figure 7 Shown include:

[0094] S701. Compare the distances measured by the two sets of limit laser sensors to see if they are consistent.

[0095] If the distances measured by the limit laser sensor are inconsistent, it means that the vehicle position does not meet the requirements. In order to further determine the problem of the vehicle position, step S702 is executed at this time.

[0096] S702: Determine whether the distances measured by the two sets of limit laser sensors are both less than the maximum measurement value.

[0097] Among them, the maximum measurement value is the distance measured by the limit laser sensor when there is no object in the battery exchange channel.

[0098] If it is determined that the distances measured by the two sets of limit laser sensors are not both less than the maximum measurement value, that is, it is determined that only one set of limit laser sensors measures a distance less than the maximum measurement value, it means that the vehicle is too close or too far from the battery exchange equipment, resulting in one set of limit laser sensors not measuring the vehicle, so step S703 is executed at this time. If it is determined that the distances measured by the two sets of limit laser sensors are both less than the maximum measurement value, it means that both sets of limit laser sensors measure the vehicle, but due to the deflection of the vehicle body, the measured parts are different, so step S704 is executed at this time.

[0099] S703: Voice prompt: The distance between the vehicle to be replaced and the battery replacement equipment does not meet the distance requirement.

[0100] In order to allow the driver to more accurately understand whether the parking distance of the vehicle is too close or too far, so as to accurately adjust it without manual judgment, in another embodiment of the present application, a specific implementation of step S703 includes:

[0101] When the distance measured by the first set of limit laser sensors is less than the maximum measurement value, a prompt message is sent to the speaker indicating that the vehicle is too close to the electrical equipment.

[0102] When the distance measured by the second set of limit laser sensors is less than the maximum measurement value, a prompt message is sent to the speaker indicating that the vehicle is too far away from the electrical equipment.

[0103] The first group of position-limiting laser sensors are position-limiting laser sensors that are closer to the battery swapping equipment, and the second group of position-limiting laser sensors are position-limiting laser sensors that are farther from the battery swapping equipment.

[0104] S704: Voice prompt that the body of the vehicle to be replaced is skewed.

[0105] Similarly, in order to allow the driver to more accurately understand the direction of the vehicle's deflection so as to accurately adjust it without manual judgment, in another embodiment of the present application, a specific implementation of step S704 includes:

[0106] When the distance measured by the first group of limit laser sensors is greater than the distance measured by the second group of limit laser sensors, a prompt message is sent to the speaker that the body of the vehicle to be replaced is tilted to the left.

[0107] When the distance measured by the first group of limit laser sensors is smaller than the distance measured by the second group of limit laser sensors, a prompt message is sent to the speaker that the body of the vehicle to be replaced is tilted to the right.

[0108] Optionally, in order to more effectively limit the position of the vehicle, in another embodiment of the present application, each group of position-limiting laser sensors includes two position-limiting laser sensors whose heights are both lower than the chassis height of the vehicle to be replaced. Accordingly, in the embodiment of the present application, a specific implementation of step S702 includes:

[0109] When it is determined that the tires of the vehicle to be replaced are beyond the area between two limit laser sensors in any set of limit laser sensors based on the distances measured by the two sets of limit laser sensors, a voice prompt is given that the distance between the vehicle to be replaced and the battery replacement equipment does not meet the distance requirements.

[0110] Among them, the distance between two limit laser sensors in a group of limit laser sensors is set based on the tire width of the vehicle to be replaced.

[0111] When the distances measured by the individual limit laser sensors in the two groups of limit laser sensors are inconsistent, a voice prompt is given that the body of the vehicle to be replaced is skewed.

[0112] Specifically, for a group of limit laser sensors, when the distance measured by each limit laser sensor is the maximum measurement distance, it means that the tire of the vehicle exceeds the area between the two limit laser sensors. At this time, it can be prompted that the distance between the vehicle to be replaced and the battery replacement equipment does not meet the distance requirements. Among them, if the distance measured by the limit laser sensor close to the battery replacement equipment is the maximum measurement distance, it is prompted that the distance is too far. If the distance measured by the limit laser sensor far away from the battery replacement equipment is the maximum measurement distance, it is prompted that the distance is too close.
