Description

A horizontal tilt angle measurement and reset device and method

[0001] Technology

[0002] This invention relates to the field of electric vehicle battery swapping technology, and in particular to a horizontal tilt angle measurement and reset device and method. Background Technology

[0003] With the rapid development of the electric vehicle industry, battery swapping technology, as an effective means to solve range anxiety, is receiving increasing attention from the market. Battery swapping technology refers to the process of quickly replacing the battery when an electric vehicle's charge is depleted, thus extending its driving range. However, in practical applications, battery swapping technology faces a significant challenge: how to accurately and efficiently complete battery replacement when the vehicle is parked and may be tilted.

[0004] Currently, most battery swapping devices on the market are designed for battery replacement when the vehicle is level. However, when a vehicle is parked and tilted, the battery is also tilted, which presents the following challenges for battery swapping operations:

[0005] Battery access difficulties: Due to the tilt of the battery, traditional battery swapping equipment has difficulty accurately grabbing the battery, which can easily lead to access failure.

[0006] Unstable battery installation: When tilted, it is difficult to accurately match the installation position between the battery and the vehicle, affecting the installation stability of the battery.

[0007] Low battery swapping efficiency: Due to the tilt of the battery, more time is needed to adjust the battery position during the swapping process, resulting in reduced battery swapping efficiency.

[0008] Safety hazards: Replacing the battery while it is tilted can easily lead to safety accidents such as the battery falling off or short circuit.

[0009] There is currently no effective solution to the above problems in the existing technology. Therefore, it is necessary to study a horizontal tilt angle measurement and reset device and method to achieve accurate connection and installation of batteries in tilted states. Summary of the Invention

[0010] The purpose of this invention is to provide a horizontal tilt angle measurement and reset device and method to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, the present invention provides the following solution:

[0012] A horizontal tilt angle measuring and resetting device includes a support platform, a mounting frame is provided at the bottom end of the support platform, and a notch is provided on the support platform at the position corresponding to the mounting frame;

[0013] Four sets of lifting devices are installed on the mounting frame, and the four sets of lifting devices are arranged sequentially around the inside of the mounting frame.

[0014] The top of the four sets of lifting devices is equipped with a load-bearing plate;

[0015] The top four corners of the supporting plate are equipped with sensing components, and the four sets of lifting devices are connected to the four sensing components one by one through the control unit.

[0016] Furthermore, the lifting device includes an electric push rod, a guide rail, a slider, a hinge seat, a first hinge rod, and a second hinge rod;

[0017] The guide rail and the slider are slidably engaged and arranged within the mounting frame, and the hinge seat is connected to the slider.

[0018] One end of the first hinge rod is hinged in the hinge seat, and the other end of the first hinge rod is hinged to the bottom end of the lifting plate.

[0019] One end of the second hinge rod is hinged to the body of the first hinge rod, and the other end of the second hinge rod is hinged within the mounting frame;

[0020] The output end of the electric push rod is connected to the hinge seat.

[0021] Furthermore, the supporting plate includes a lifting plate and a rotating plate;

[0022] The lifting plate is located on top of the four sets of lifting devices. A rotating mechanism is located on top of the lifting plate, and the rotating plate is located on top of the rotating mechanism. The rotating mechanism drives the rotating plate to rotate 90° in a clockwise or counterclockwise direction.

[0023] The sensing components are respectively arranged at the four corners of the top of the rotating plate.

[0024] Furthermore, the rotating mechanism includes a rotating motor, a bearing gear, and a rotating gear;

[0025] The rotating motor is mounted on the lifting plate, and the output end of the rotating motor is provided with the drive gear;

[0026] The outer ring of the bearing gear is fixedly installed at the bottom of the rotating plate, and the inner ring of the bearing gear is fixedly installed at the top of the lifting plate;

[0027] The rotating gear meshes with the outer ring of the bearing gear.

[0028] Furthermore, the present invention also provides a method for measuring and resetting horizontal tilt angle, which is applied to the aforementioned horizontal tilt angle measuring and resetting device.

[0029] The method for measuring horizontal tilt angle includes the following steps:

[0030] Step 11: The four sets of lifting devices on the support platform simultaneously lift the support plate, and the four sensing components located on the support plate respectively sense the vertical distance between it and the object above.

[0031] Step 12: When the sensing component detects that the vertical distance between itself and the object above is less than or equal to the threshold, the sensing component stops the lifting process of the corresponding lifting device through the control unit until all four lifting devices stop lifting.

[0032] Step 13: The control unit records the movement distance data of each of the four lifting devices;

[0033] The method for restoring horizontal tilt angle includes the following steps:

[0034] Step 21: The four sets of lifting devices on the support platform simultaneously lift the support plate, causing the object carried on the support plate to move upward;

[0035] Step 22: The control unit retrieves the movement distance data of the four sets of lifting devices recorded in step 13, and controls the four sets of lifting devices to lift the load-bearing plate according to their respective movement distance data.

[0036] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of the present invention are as follows:

[0037] This invention uses four independent lifting devices to lift the supporting plate, thereby changing the tilt angle of the supporting plate. This allows the device to support objects at different tilt angles, keeping the object in its original state before being picked up, or adjusting the supported object to different tilt angles to meet various situations, making it highly adaptable.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0048] Example 1

[0049] A horizontal tilt angle measurement and reset device is proposed. Based on the actual situation of the battery swapping station, this embodiment can be modified by using the existing transfer trolley for transferring batteries at the battery swapping station.

[0050] Referring to Figures 1-3, the transfer trolley 1 is equipped with a carrying platform 11, and an installation frame 2 is provided on the bottom end of the carrying platform 11. A notch 12 is provided on the carrying platform 11 at the position corresponding to the installation frame 2.

[0051] Four sets of lifting devices 3 are installed inside the mounting frame 2. The four sets of lifting devices 3 are arranged in sequence around the inside of the mounting frame 2. The lifting ends of the four sets of lifting devices 3 protrude from the notch 12 and are equipped with load-bearing plates.

[0052] It should be noted that the lifting ends of the four sets of lifting devices 3 are all located at the four corners of the supporting plate.

[0053] In addition, sensing components 7 are respectively arranged at the top four corners of the supporting plate. The four sets of lifting devices 3 are connected to the four sensing components 7 one by one through the control unit (not shown in the figure, which is a conventional electrical signal connection technology for those skilled in the art, and will not be described in detail here).

[0054] Specifically, the support plate is raised by four independent lifting devices 3, thereby changing the tilt angle of the support plate. After the sensing component 7 detects the battery compartment or battery, the lifting of the support plate stops. The battery compartment or battery can be received in the most appropriate state when it is not horizontal. Furthermore, the new battery can be installed back in its original state according to the tilt angle of the battery compartment or battery when it is received, ensuring the correctness of the installation.

[0055] Referring to Figures 1-3, the above technical solution is optimized as follows:

[0056] The supporting plates include a lifting plate 4 and a rotating plate 6;

[0057] The lifting plate 4 is located on top of the four lifting devices 3. The top of the lifting plate 4 is equipped with a rotating mechanism 5, and the top of the rotating mechanism 5 is equipped with the rotating plate 6. The rotating mechanism 5 drives the rotating plate 6 to rotate 90° in a clockwise or counterclockwise direction.

[0058] Sensing components 7 are arranged at the four corners of the top of the rotating plate 6.

[0059] Specifically, when the battery orientation needs to be adjusted under special circumstances, the rotating plate 6 takes the battery and then rotates through the rotating mechanism 5 to change the battery orientation.

[0060] It should be noted that the rotating mechanism 5 drives the rotating plate 6 to rotate 90° clockwise or counterclockwise to accommodate two battery installation orientations in actual situations (installation with the length direction facing forward or installation with the width direction facing forward).

[0061] Example 2

[0062] Referring to Figures 2 and 3, the horizontal tilt angle measuring and resetting device provided in this embodiment differs from that in Embodiment 1 in that the rotating mechanism 5 adopts the following structure:

[0063] The rotating mechanism 5 includes a rotating motor 51, a bearing gear 52, and a rotating gear 53;

[0064] A rotating motor 51 is mounted on the lifting plate 4, and a drive gear is provided at the output end of the rotating motor 51.

[0065] The outer ring of the bearing gear 52 is fixedly installed at the bottom of the rotating plate 6, and the inner ring of the bearing gear 52 is fixedly installed at the top of the lifting plate 4.

[0066] Rotating gear 53 meshes with the outer ring of bearing gear 52.

[0067] Specifically, when the rotating motor 51 drives the rotating gear 53 to rotate, it will cause the outer ring of the bearing gear 52 to rotate around the inner ring of the bearing gear 52, thereby driving the rotating plate 6 to rotate.

[0068] Example 3

[0069] Referring to Figures 2 and 3, the horizontal tilt angle measurement and reset device provided in this embodiment differs from that in Embodiment 1 in that the lifting device 3 specifically adopts the following structure:

[0070] The lifting device 3 includes an electric push rod 31, a guide rail 32, a slider 33, a hinge seat 34, a first hinge rod 35, and a second hinge rod 36.

[0071] The guide rail 32 and the slider 33 are slidably engaged and arranged in the mounting frame 2, and the hinge seat 34 is connected to the slider 33;

[0072] One end of the first hinge rod 35 is hinged to the hinge seat 34, and the other end of the first hinge rod 35 is hinged to the bottom end of the bearing plate.

[0073] One end of the second hinge rod 36 is hinged to the body of the first hinge rod 35, and the other end of the second hinge rod 36 is hinged inside the mounting frame 2. The second hinge rod 36 and the first hinge rod 35 are in a "V" shape.

[0074] The output end of the electric actuator 31 is connected to the hinge seat 34.

[0075] It should be noted that the tops of the four first hinge rods 35 are respectively located at the four corners of the bottom of the load-bearing plate.

[0076] Example 4

[0077] This embodiment provides a method for measuring and resetting horizontal tilt angle, which is applied to the horizontal tilt angle measuring and resetting device in any of the embodiments 1 to 3 above.

[0078] The method for measuring and resetting the horizontal tilt angle is divided into a horizontal tilt angle measurement method and a horizontal tilt angle resetting method, among which,

[0079] The method for measuring horizontal tilt angle includes the following steps:

[0080] Step 11: The four sets of lifting devices 3 on the support platform 11 simultaneously lift the support plate, and the four sensing components 7 located on the support plate respectively sense the vertical distance between it and the object above (such as a battery or battery compartment, the same below).

[0081] Step 12: When the sensing component 7 detects that the vertical distance between itself and the object above is less than or equal to the threshold (a set value that can be adjusted as needed), the sensing component 7 stops the lifting process of the corresponding lifting device 3 through the control unit until all four lifting devices 3 stop lifting.

[0082] Step 13: The control unit records the movement distance data of each of the four lifting devices 3.

[0083] The method for restoring horizontal tilt angle includes the following steps:

[0084] Step 21: The four sets of lifting devices 3 on the support platform 11 simultaneously lift the support plate, causing the object carried on the support plate to move upward;

[0085] Step 22: The control unit retrieves the movement distance data of the four sets of lifting devices 3 recorded in step 13, and controls the four sets of lifting devices 3 to lift the load-bearing plate according to their respective movement distance data.

[0086] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, 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 the present invention.
