Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery swapping technology, and in particular to an angle measurement and angle reset device. Background Technology

[0002] Against the backdrop of the rapid development of the electric vehicle industry, battery swapping technology, as one of the core means to solve range anxiety, is constantly expanding its application scenarios, placing higher demands on the accuracy and adaptability of the battery swapping process. Among them, chassis battery swapping is currently the mainstream battery swapping mode. This mode involves removing the depleted battery from the battery compartment at the bottom of the vehicle, transporting it to the charging area by a transfer vehicle, and then transporting the fully charged battery to the bottom of the vehicle by the transfer vehicle and installing it into the battery compartment, thus completing the battery swapping process.

[0003] However, existing chassis battery swapping technology has significant limitations: when a vehicle parks at a battery swapping station, the actual parking angle often deviates from the standard battery swapping angle due to factors such as driver operating habits and the accuracy of parking assistance equipment. This results in a misalignment of the battery's placement angle on the transfer trolley after it is removed from the vehicle's underside. This angular deviation directly leads to two core problems: first, insufficient alignment accuracy between the transfer trolley and the battery during battery retrieval may cause battery damage or retrieval failure; second, during battery installation, the misaligned battery cannot be precisely matched with the battery compartment at the bottom of the vehicle, not only prolonging the battery swapping time but also potentially damaging the battery or vehicle's connection structure due to forced installation, seriously affecting the safety and reliability of battery swapping. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following solution: An angle measurement and angle reset device includes a panel for carrying a battery, and two sets of first reset mechanisms are correspondingly arranged on the panel. Each of the first reset mechanisms includes a first reset push bar arranged along the first direction of the panel and a first drive mechanism that drives the first reset push bar to reciprocate in a direction perpendicular to the arrangement direction of the first reset push bar. The first driving mechanism includes two sets of first driving motors arranged at the bottom end of the panel, and the movement direction of the output end of the first driving motor is perpendicular to the arrangement direction of the first reset push bar. The panel has a first slot along the direction of movement of the output end of the first drive motor. The output ends of the two sets of the first drive motors are respectively connected to the two ends of the first reset push bar through the first slot; A plurality of first sensors are mounted on the first reset push bar along its layout direction, and the first sensors are electrically connected to the first drive mechanism through a control unit.

[0007] Furthermore, it also includes two sets of second reset mechanisms correspondingly arranged on the panel; Each group of the second reset mechanism includes a second reset push block arranged along the second direction of the panel and a second drive mechanism that drives the second reset push block to reciprocate along the first direction of the panel. A second sensor is mounted on the second reset push block along its layout direction, and the second sensor is electrically connected to the second drive mechanism through the control unit.

[0008] Furthermore, the second driving mechanism includes a second driving part, which is connected to the second reset push block.

[0009] Furthermore, the second drive unit includes a second drive motor, a rectangular pull wire assembly, and a connecting base; The direction of motion of the output end of the second drive motor is perpendicular to the direction of motion of the second reset push block; The rectangular pull wire assembly includes four sets of pull wire seats arranged in a rectangle, and each set of pull wire seats is equipped with a rotating wheel that rotates horizontally.

Detailed Implementation

[0015] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0016] Example 1 See Figure 1-3 As shown, this embodiment provides an angle measurement and angle reset device, including a panel 1 for carrying a battery, and two sets of first reset mechanisms 2 are correspondingly arranged on the panel 1. Each set of first reset mechanisms 2 includes a first reset push bar 2-1 arranged along the first direction of panel 1 (in this embodiment, it can be defined as the length direction) and a first drive mechanism 2-2 that drives the first reset push bar 2-1 to reciprocate in a direction perpendicular to the arrangement direction of the first reset push bar 2-1. The first drive mechanism 2-2 includes two sets of first drive motors 2-201 arranged at the bottom of the panel 1. The direction of movement of the output end of the first drive motor 2-201 is perpendicular to the arrangement direction of the first reset push bar 2-1. A first slot 1-1 is provided on panel 1 along the movement direction of the output end of the first drive motor 2-201; The output ends of the two sets of first drive motors 2-201 are respectively connected to the two ends of the first reset push bar 2-1 through the first slot 1-1; Several first sensors 2-3 are installed on the first reset push bar 2-1 along its layout direction. The first sensors 2-3 are electrically connected to the first drive mechanism 2-2 through the control unit.

[0017] It should be noted that the two first reset push bars 2-1 move closer or further apart under the drive of the two first drive mechanisms 2-2, thereby "correcting" the battery with angular deviation.

[0018] It should be noted that the detection direction of the first sensor 2-3 is parallel to the movement direction of the first reset push bar 2-1, and the detection directions of the first sensors 2-3 on the two first reset push bars 2-1 are opposite to each other.

[0019] Specifically, the movement of the two first reset push bars 2-1 is driven by the two sets of first drive mechanisms 2-2 in coordination, which can fit the angle of the battery. The data is then recorded by several first sensors 2-3. When the transfer trolley is loaded with a fully charged battery again, the two sets of first drive mechanisms 2-2 can drive the two first reset push bars 2-1 to move again according to the data recorded by the several first sensors 2-3, so as to adjust the angle of the battery and reset the battery to the angle of the "original battery", so that it can be accurately loaded into the vehicle.

[0020] It should be noted that this utility model can be applied not only to batteries, but also to corrective battery compartments (where the battery is located inside the battery compartment).

[0021] In addition, to facilitate guiding the movement direction of the output end of the first drive motor 2-201 and ensure the movement direction of the first reset push bar 2-1, a first guide mechanism 2-4 is also included, which is arranged at the bottom end of the panel 1. Figure 3 The first guide mechanism 2-4 includes a first slide rail arranged parallel to the movement direction of the output end of the first drive motor 2-201 and a first slider adapted to the first slide rail; the output end of the first drive motor 2-201 is connected to the first slider.

[0022] In this embodiment, two sets of first guide mechanisms 2-4 are provided. Alternatively, one or more sets can be provided, depending on actual needs.

[0023] Example 2 See Figure 1-3 As shown, the angle measurement and angle reset device provided in this embodiment also includes two sets of second reset mechanisms 3 correspondingly arranged on the panel 1; Each group of the second reset mechanism 3 includes a second reset push block 3-1 arranged along the second direction of the panel 1 (in this embodiment, it can be defined as the width direction; specifically, the first direction and the second direction are perpendicular to each other on the plane) and a second drive mechanism 3-2 that drives the second reset push block 3-1 to reciprocate along the first direction of the panel 1. A second sensor 3-3 is installed on the second reset push block 3-1 along its layout direction. The second sensor 3-3 is electrically connected to the second drive mechanism 3-2 through the control unit.

[0024] It should be noted that the two second reset push blocks 3-1 move closer or further apart under the drive of the two second drive mechanisms 3-2.

[0025] It should be noted that the detection direction of the second sensor 3-3 is parallel to the movement direction of the second reset push block 3-1, and the detection directions of the second sensors 3-3 on the two second reset push blocks 3-1 are opposite to each other.

[0026] Specifically, the first reset mechanism 2 records the angle information of two side walls of the battery (or battery compartment) and adjusts the angle of the side walls, while the second reset mechanism 3 can record the angle information of the other two side walls of the battery (or battery compartment) and adjust the angle of the side walls, thereby ensuring that the angles of all four side walls of the battery (or battery compartment) can be recorded and adjusted, ensuring accuracy.

[0027] Specifically, the second drive mechanism 3-2 includes a second drive unit, which is connected to the second reset push block 3-1.

[0028] Specifically, the second drive unit includes a second drive motor 3-201, a rectangular pull wire assembly 3-202, and a connecting seat 3-203; The direction of motion of the output end of the second drive motor 3-201 is perpendicular to the direction of motion of the second reset push block 3-1; The rectangular pull wire assembly 3-202 includes four sets of pull wire seats 3-2021 arranged in a rectangular shape, and each set of pull wire seats 3-2021 is equipped with a rotating wheel 3-2022 that rotates horizontally. Four sets of rotating wheels 3-2022 are fitted with drive cables 3-204 connected end to end, and the drive cables 3-204 are rectangular. A portion of the drive cable 3-204 overlaps with the movement path of the second reset push block 3-1; The output end of the second drive motor 3-201 is connected to the drive cable 3-204; A second slot 1-2 is provided on panel 1 along the movement path of the second reset push block 3-1; The second reset push block 3-1 is connected to the connecting seat 3-203 through the second slot 1-2; The connector 3-203 is connected to a portion of the drive pull wire 3-204 that overlaps with the motion path of the second reset push block 3-1.

[0029] When the output end of the second drive motor 3-201 extends or retracts, it drives the drive cable 3-204 to rotate, which in turn drives the connecting seat 3-203 to move, and further drives the second reset push block 3-1 to move.

[0030] In addition, to ensure the movement direction of the second reset push block 3-1, a second guide mechanism 3-4 is also included, which is located at the bottom of the panel 1. Figure 3 The second guide mechanism 3-4 includes a second slide rail arranged parallel to the movement path of the second reset push block 3-1 and a second slider adapted to the second slide rail; the connecting seat 3-203 connects to the second slider.

[0031] Specifically, panel 1 can be installed on top of the transfer trolley to facilitate battery adjustment and transfer in conjunction with the transfer trolley.

[0032] It should be noted that both the first sensor 2-3 and the second sensor 3-3 are proximity sensors. After the sensor detects proximity, it sends a stop command to the drive motor, and the PLC records the distance pushed out by the push rod of the drive motor.

[0033] Specifically, this technology can adjust the angle of the battery carried on the panel 1 through the cooperation of the first reset mechanism 2 and the second reset mechanism 3. After the battery is taken out, it can be adjusted to a suitable position. When the battery is installed, the battery can also be readjusted to the angle suitable for vehicle installation. That is, the battery can be adjusted after it is removed and when it is installed.

[0034] This document uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
