Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, and in particular to a chassis assembly, a battery-swap vehicle, a battery-swap robot, and a charging and swapping station. Background Art

[0002] For new energy vehicles, especially pure electric vehicles, battery swapping is a way to quickly replenish energy in a short period of time, so this method is favored by Everbright car owners. The battery swapping process is generally carried out in a charging and swapping station, which is equipped with a battery swapping platform, a battery compartment and a battery swapping robot. The battery swapping robot moves back and forth between the battery compartment and the battery swapping platform to remove the depleted battery from the vehicle to be replaced and install the fully charged power battery to the vehicle to be replaced.

[0003] During the battery swap process, how to accurately install the battery on the vehicle chassis is one of the key factors that determine the success rate of the battery swap. Usually, there is no relative positioning relationship between the chassis of the vehicle to be swapped and the battery, so it is necessary to use a battery swap robot for positioning. The current battery swap robot is equipped with two sets of positioning components, one set for positioning with the vehicle chassis, and one set for positioning with the battery, so that the positioning between the battery and the vehicle chassis is indirectly achieved through the battery swap robot. However, according to the current manufacturing and assembly level, for any of the above-mentioned pairs of positioning relationships, it is relatively easy to control the positioning error between the vehicle chassis and the battery swap robot alone, or to control the positioning error between the battery and the battery swap robot alone, while it is more difficult to control the error between the two sets of positioning relationships at the same time, and it is easy to cause positioning failure due to large relative errors, resulting in a reduction in the success rate of battery swap.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Utility Model Content

[0006] The above-mentioned technical solution of the present application, by setting the battery positioning holes corresponding to the vehicle body positioning holes after the battery pack is installed, makes it possible for the battery pack and the vehicle chassis to be positioned using the same positioning reference, thereby avoiding the problem of positioning failure caused by the large error between the two sets of positioning relationships and improving the success rate of battery replacement.

[0007] In the preferred technical solution of the above chassis assembly, the diameter of the battery positioning hole is larger than the diameter of the vehicle body positioning hole.

[0009] In the preferred technical solution of the above chassis assembly, the number of the battery positioning hole and the number of the vehicle body positioning hole are both two.

[0018] By setting the first pin segment and the second pin segment of the locating pin, and the outer diameter of the first pin segment is smaller than the outer diameter of the second pin segment, it is possible to effectively avoid the locating pin from getting stuck due to excessive extension when withdrawing from the battery locating hole and the vehicle body locating hole, thereby improving the success rate of battery replacement.

[0030] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. For example, although the accompanying drawings illustrate the example of two battery positioning holes and two body positioning holes, this quantitative relationship is not static, and those skilled in the art can adjust it as needed to adapt to specific applications.

Therefore, it cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, "multiple" refers to at least two.

[0032] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0033] First refer to Figure 1 and Figure 2 , a brief introduction to the chassis assembly of this application is given.

[0034] like Figure 1 and Figure 2 As shown, in order to solve the problem of low success rate of positioning the battery and the vehicle to be replaced during the battery replacement process, the chassis assembly 10 of the present application includes a chassis body 11 and a battery pack 12. A battery mounting position 111 is provided on the chassis body 11, and the battery pack 12 is detachably mounted on the mounting position 111. A plurality of vehicle body positioning holes 112 are also provided on the chassis body 11, and a plurality of battery positioning holes 121 are provided on the battery pack 12. When the battery pack 12 is installed on the mounting position 111, for each battery positioning hole 121, there is a vehicle body positioning hole 112 corresponding to its axial direction.

[0035] During the battery replacement process of the chassis assembly 10 of the present application, the positioning piece (taking the positioning pin as an example) on the battery replacement robot 20 rises and passes through the battery positioning hole 121 and the vehicle body positioning hole 112 in sequence, completing the positioning of the battery replacement robot 20 and the low-charge battery pack on the chassis body 11, and then the locking and unlocking device on the battery replacement robot 20 unlocks the battery pack 12, and the low-charge battery pack is thus removed. The battery replacement robot 20 then transfers the low-charge battery pack to the battery rack, receives the fully-charged battery pack from the battery rack, and then positions it with the battery positioning hole 121 on the battery pack through the positioning piece. Next, the battery replacement robot 20 carries the fully-charged battery pack and moves it to the bottom of the chassis assembly 10, and lifts the fully-charged battery pack. During the lifting process, the positioning piece in the positioning state with the battery positioning hole 121 extends into the vehicle body positioning hole 112 to achieve positioning with the vehicle body, and then continues to lift until the fully-charged battery pack is lifted to the installation position 111. Finally, the locking and unlocking mechanism on the battery replacement robot 20 locks the fully-charged battery pack, and the battery replacement is completed.

[0036] It can be seen that the above technical solution of the present application, through the arrangement of the battery positioning hole 121 corresponding to the vehicle body positioning hole 112 after the battery pack 12 is installed, enables the battery pack 12 and the vehicle chassis to be positioned using the same positioning reference, thereby avoiding the problem of positioning failure caused by the large error between the two sets of positioning relationships, and improving the success rate of battery replacement.

[0037] Combine the following Figures 1 to 3 , a preferred implementation manner of the chassis assembly of the present application is introduced.

[0038] like Figures 1 to 3 As shown, in a preferred technical solution, the chassis assembly 10 includes a chassis body 11 and a battery pack 12. A mounting position 111 is provided on the lower side of the chassis body 11 (the side close to the ground after assembly, the same below). The mounting position 111 is preferably a mounting groove formed by an inward depression from the lower side. After the battery pack 12 is installed in the mounting groove, it is basically flush with the lower side of the chassis. The battery pack 12 includes an outer shell and a battery cell arranged in the outer shell. The outer shell forms a accommodating cavity. The battery cell is installed in the accommodating cavity. A connecting frame is formed around the outer shell. The height of the connecting frame is less than the height of the accommodating cavity. The depth of the mounting groove is adapted to the battery, and its depth is relatively deep, and is used to accommodate the accommodating cavity of the outer shell. A grid support rib is provided on the outer side of the mounting groove. The height of the grid support rib is higher than the mounting groove but lower than the lower side of the chassis body 11, and is used to accommodate the connecting frame. Two battery positioning holes 121 are provided on the connecting frame of the outer shell. The two battery positioning holes are arranged along the diagonal direction of the outer shell, such as Figure 1As shown, the two battery positioning holes 121 are respectively arranged at the upper left corner and the lower right corner of the connecting frame. Preferably, the battery positioning hole 121 is a circular through hole. Correspondingly, two body positioning holes 112 are arranged on the grid support ribs around the mounting groove, and the body positioning holes 112 are preferably also circular through holes. Among them, the aperture of each battery positioning hole 121 is larger than the aperture of the corresponding body positioning hole 112. In this way, when the battery pack 12 is installed to the mounting position 111, the two battery positioning holes 121 on the battery pack 12 correspond one by one to the two body positioning holes 112 on the mounting position 111 in the axial direction.

[0039] It should be noted that, in theory, when the battery pack 12 is installed on the mounting position 111, the axis of each battery positioning hole 121 should coincide with the corresponding vehicle body positioning hole 112. However, due to the current manufacturing accuracy and other reasons, it is difficult to achieve the situation where the axis coincides in practice. Therefore, there is a certain slight deviation between the axis of the battery positioning hole 121 and the axis of the vehicle body positioning hole 112, but this slight deviation does not affect the positioning between the two. Therefore, the axial correspondence between the battery positioning hole 121 and the vehicle body positioning hole 112 in this application means that the axis of the battery positioning hole 121 and the vehicle body positioning hole 112 coincide or there is a slight deviation, and the deviation can be, for example, 0-5mm (for example only).

[0040] The above setting method uses multiple positioning holes for positioning, which is conducive to improving positioning accuracy. The setting method in which the aperture of the battery positioning hole 121 is larger than the aperture of the body positioning hole 112 is conducive to reducing the difficulty of positioning and improving the success rate of battery replacement.

[0041] It should be noted that the above preferred implementations are only used to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. Without departing from the principles of the present application, those skilled in the art may adjust the above settings so that the present application can be applied to more specific application scenarios.

[0042] For example, in an alternative embodiment, although the above embodiment is described by taking two body locating holes 112 as an example and two battery locating holes 121 as an example in combination with the chassis body 11, the number of body locating holes 112 and battery locating holes 121 is not restrictive, and those skilled in the art can adjust them based on actual application scenarios. For example, the number of battery locating holes 121 can also be one, three or more; the number of battery locating holes 121 can also be greater than the number of body locating holes 112, so that the battery pack 12 can be installed on chassis of different specifications; the number of body locating holes 112 can also be greater than the number of battery locating holes 121, so that the chassis body 11 can be installed with battery packs 12 of different specifications.

[0043] For another example, in another alternative embodiment, the battery positioning hole 121 having a larger diameter than the body positioning hole 112 is only a preferred embodiment, and those skilled in the art may adjust it. For example, the battery positioning hole 121 may also have a diameter equal to the body positioning hole 112, but of course this setting will not be conducive to improving the positioning success rate.

[0044] For example, in another alternative embodiment, the setting position of the battery positioning hole 121 is not fixed. In addition to being set along the diagonal direction of the battery pack 12, it can also be adjusted to other settings, such as being set on the same side of the connecting frame, or being set respectively in the middle of the two opposite sides of the connecting frame, etc.

[0045] For example, in another alternative embodiment, the location of the battery positioning hole 121 is not unique, and those skilled in the art may adjust it, such as expanding the range of the mounting slot and setting the vehicle body positioning hole 112 inside the mounting slot.

[0046] For example, in another replaceable embodiment, in addition to using a mounting groove, the mounting position 111 may also be adjusted by a person skilled in the art, such as using a mounting plane as the mounting position 111. In this case, when the battery pack 12 is installed, the lower side of the battery pack 12 will protrude from the lower side of the chassis body 11.

[0047] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-coordinated manner to combine new implementations to suit more specific application scenarios.

[0048] The present application also provides a battery-swappable vehicle, which includes the chassis assembly 10 in the above-mentioned embodiment.

[0049] The battery-swap vehicle of the present application, by setting the above-mentioned chassis assembly 10, makes it possible for the battery positioning hole 121 to correspond to the vehicle body positioning hole 112 after the battery pack 12 is installed, so that the battery pack 12 and the vehicle chassis can be positioned using the same positioning reference, avoiding the problem of positioning failure caused by the large error between the two sets of positioning relationships, thereby improving the success rate of battery replacement.

[0050] Refer to the following Figure 4 and Figure 5 , the battery-swapping robot of this application is introduced.

[0051] like Figure 4 and Figure 5As shown, the present application also provides a battery swap robot 20 for swapping batteries for the battery swappable vehicle of the above technical solution. The battery swap robot 20 includes a robot body 21 and a positioning pin 22 arranged on the robot body 21, and the positioning pin 22 is arranged to be able to be inserted into the battery positioning hole 121 and the vehicle body positioning hole 112 at the same time.

[0052] In a possible implementation, the robot body 21 includes a base, a lifting device and a battery carrying device. The lifting device is fixedly connected to the base, and the battery carrying device is connected to the lifting device. The lifting device can be, for example, a scissor-type lifting device, which can drive the battery carrying device to move up and down. The battery carrying device is provided with a locking and unlocking structure and a positioning pin 22. The battery carrying device is used to lock and unlock the battery pack 12, and the positioning pin 22 is used for positioning between the battery pack 12 and the chassis body 11. In the present application, two positioning pins 22 are provided, and the two positioning pins 22 are arranged along the diagonal direction of the battery carrying device. Preferably, the positioning pin 22 can be raised and lowered, and the specific lifting method of the positioning pin 22 is a conventional technical means in the field, which will not be repeated in this application.

[0053] See also Figure 5 The positioning pin 22 includes a first pin segment 221 and a second pin segment 222 from top to bottom. The first pin segment 221 and the second pin segment 222 are both columnar. The outer diameter of the first pin segment 221 is smaller than the outer diameter of the second pin segment 222, and the top of the first pin segment 221 has a chamfer.

[0054] In this way, during the battery replacement process, the battery replacement robot 20 uses the battery carrying part to carry the battery pack 12, and simultaneously achieves positioning with the battery positioning hole 121 and the vehicle body positioning hole 112 through the lifting and lowering of the positioning pin 22.

[0055] The battery swap robot 20 of the present application can use the same positioning pin 22 to achieve positioning between the battery pack 12 and the vehicle chassis by setting a positioning pin 22 to be inserted into the battery positioning hole 121 and the vehicle body positioning hole 112 at the same time, which is beneficial to improving positioning accuracy and battery swap success rate. By setting the first pin segment 221 and the second pin segment 222 by the positioning pin 22, and the outer diameter of the first pin segment 221 is smaller than the outer diameter of the second pin segment 222, it can effectively avoid the positioning pin 22 from being stuck due to the excessive insertion distance when exiting the battery positioning hole 121 and the vehicle body positioning hole 112, thereby improving the battery swap success rate.

[0056] Of course, the specific setting method of the above-mentioned battery-swapping robot 20 is only exemplary, and those skilled in the art can adjust it as long as the adjustment does not deviate from the principle of the present application. For example, the specific form of the robot body 21 is not restrictive, and those skilled in the art can adjust it as long as the robot body 21 can install the positioning pin 22 and lock and unlock the battery pack 12. For another example, the number of positioning pins 22 is not fixed, and those skilled in the art can adjust it. For example, the number of positioning pins 22 can also be one, three or more, so that the battery-swapping robot 20 can be suitable for positioning battery packs 12 and chassis of various specifications. For another example, although the above-mentioned embodiment is introduced in conjunction with the lifting and lowering of the positioning pin 22 as an example, this is not restrictive, and the positioning pin 22 can also be fixedly set on the robot body 21. For another example, the specific structure of the positioning pin 22 is not unique. In addition to the first pin segment 221 and the second pin segment 222 described above, those skilled in the art can make adjustments based on specific application scenarios. For example, the positioning pin 22 has the same outer diameter as a whole; for another example, the positioning pin 22 is tapered from top to bottom; for another example, the positioning pin 22 includes three or more sections, etc.

[0057] The present application also provides a charging and swapping station, which includes the battery swapping robot 20 of the above embodiment.

[0058] The charging and swapping station of the present application, by providing the above-mentioned battery swapping robot 20, can use the same positioning pin 22 to achieve positioning between the battery pack 12 and the vehicle chassis, which is beneficial to improving positioning accuracy and battery swapping success rate.

[0059] A possible battery replacement process of the charging and swapping station of the present application is introduced below.

[0060] In one possible implementation process, the vehicle to be replaced enters the charging and swapping station and parks at the battery swapping position. The battery swapping robot 20 moves to the bottom of the vehicle to be replaced, and the lifting device is actuated to drive the battery carrying device to rise to the chassis of the vehicle to be replaced. At this time, the positioning pin 22 rises and extends into the battery positioning hole 121 of the low-power battery pack, and the positioning of the battery swapping robot 20 and the low-power battery pack is completed. Then, the unlocking device is actuated to unlock the low-power battery pack, and the low-power battery pack is detached from the installation position 111 and carried on the battery carrying device. Next, the lifting device is actuated to drive the battery carrying device and the low-power battery pack to descend together. After descending to the initial position, the battery swapping robot 20 carries the low-power battery pack to the battery compartment, transfers the low-power battery pack to the battery compartment, and receives the fully charged battery pack from the battery compartment. During the receiving process, the positioning pin 22 is used to position the fully charged battery pack. Then the battery-swapping robot 20 carries the fully-charged battery pack and moves again to the bottom of the vehicle to be replaced. The lifting device drives the battery-carrying device to rise to the chassis of the vehicle to be replaced, and the positioning pin 22 in the positioning state with the fully-charged battery pack extends into the vehicle body positioning hole 112 to achieve the positioning between the fully-charged battery pack and the chassis body 11. Finally, the locking and unlocking device is activated to lock the fully-charged battery pack. After the locking is completed, the lifting device drives the battery-carrying device to descend, and the positioning pin 22 exits the vehicle body positioning hole 112 and the battery positioning hole 121 in turn, and the battery pack replacement is completed.

However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present application.
