Description

Technical Field

[0001] This invention relates to the field of electric vehicle battery swapping technology, and in particular to a parking platform with movable guardrails and a parking method. Background Technology

[0002] With the increasing popularity of electric vehicles, battery swapping stations are becoming increasingly important as locations for rapid energy replenishment. Currently, battery swapping stations commonly use parking platforms for vehicles to park and for battery removal and installation. However, the primary function of existing parking platforms is limited to raising the vehicle's chassis height to facilitate battery swapping operations. These parking platforms lack structures to restrict the lateral movement of the vehicle, leading to the following problems: Parking position tilt: If the vehicle body is tilted too much after it is parked on the platform, it will affect the battery replacement trolley's accurate access and installation of the battery, resulting in reduced efficiency or even operation failure.

[0003] Driver difficulty: Novice drivers may experience fear when maneuvering an electric vehicle onto a parking platform with a certain height due to a lack of precise vehicle control, which increases the risk of operational errors and may even cause the vehicle to fall off the platform, creating a safety hazard.

[0004] Therefore, there is an urgent need for a parking platform that can limit the left and right position of vehicles and automatically adjust according to different vehicle models, in order to improve the efficiency and safety of battery swapping stations. Summary of the Invention

[0005] The purpose of this invention is to provide a parking platform and parking method with movable guardrails to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution: A parking platform with movable guardrails, wherein two sets of first guardrail sections are correspondingly arranged along the length direction of the parking platform; The first guardrail section is connected to a plurality of first driving devices, and the plurality of first driving devices are respectively connected to different positions along the length of the first guardrail section. Several of the first drive devices can jointly drive the same connected first guardrail section to move toward or away from another first guardrail section.

[0007] Furthermore, the first guardrail section includes a first guardrail plate and a plurality of first vertical rollers that are sequentially rolled on the guardrail plate, wherein the axial direction of the first vertical rollers is perpendicular to the laying direction of the first guardrail plate.

[0008] Furthermore, the first guardrail section includes a first guardrail plate and a plurality of first transverse rollers that are sequentially rolled on the first guardrail plate, wherein the axial direction of the first transverse rollers is parallel to the laying direction of the first guardrail plate.

[0009] Furthermore, the first driving device includes a first electric telescopic rod, a first slider, a first slide rail, and a first connecting rod; The first electric telescopic pole is installed inside the parking platform, and the telescopic direction of the first electric telescopic pole is parallel to the width direction of the parking platform; The first slider is installed at the telescopic end of the first electric telescopic rod; The first slide rail is installed on one side of the first electric telescopic rod, and the installation direction of the first slide rail is the same as the extension direction of the first electric telescopic rod. The first slider slides in conjunction with the first slide rail; The top surface of the parking platform is provided with a first sliding groove, and the opening direction of the first sliding groove is adapted to the movement direction of the first slider. The first connecting rod is mounted on the first slider, and the end of the first connecting rod extends out of the first groove and connects to the first guardrail part.

[0010] Furthermore, the parking platform is also equipped with a number of first locking parts that correspond one-to-one with a number of the first driving devices; The first locking part is used to restrict the movement of the first slider.

[0011] Furthermore, the first locking part includes a first electric push rod and a first locking member mounted on the output end of the first electric push rod; The first electric push rod pushes the first locking member to move toward or away from the first slider; A first locking member is installed on the side of the first slider facing the first locking member, and a plurality of first locking slots are sequentially opened on the first locking member along the moving direction of the first slider. The shape of the first card slot is adapted to the shape of the first card.

[0012] Furthermore, the parking platform is provided with an upper ramp and a lower ramp at both ends along its length. Two sets of second guardrails are provided at the opposite outer edges of the ramp.

[0013] Furthermore, the end of the second guardrail portion away from the first guardrail portion is hinged to the upper platform slope; A second drive device is connected to one end of the second guardrail section near the first guardrail section; The second drive device drives one end of the second guardrail section near the first guardrail section to move towards or away from the other second guardrail section.

[0014] Furthermore, a third chute is provided on the upper ramp along its width direction; A second push-pull rod is installed inside the upper platform slope; The second guardrail part is connected to a third connecting rod at one end away from the first guardrail part, and the other end of the third connecting rod passes through the third sliding groove and is connected to the output end of the second push-pull rod. The other end of the second guardrail is connected to the end of the first guardrail.

[0015] The present invention also provides a parking method applied to the above-mentioned parking platform with movable guardrails, comprising the following steps: S1, before the battery swapping vehicle enters the parking platform, the first guardrail is located on the outermost side of the parking platform; S2, the identification system inside the battery swapping station identifies the license plate and retrieves the recorded wheel width of the vehicle; S3, the control system controls several first drive devices to move the first guardrail section to the inside of the parking platform according to the retrieved wheel width distance; S4, when the spacing of the first guardrail is equal to the sum of the retrieved wheel width and the threshold, the first drive device stops driving the first guardrail to move inward to the parking platform.

[0016] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of the present invention are as follows: Automatic adjustment of guardrail spacing: By recognizing license plates and obtaining vehicle information, the parking platform can automatically adjust the guardrail spacing to ensure that vehicles are accurately parked in the designated positions, avoiding errors in battery swapping vehicle delivery and pickup caused by crooked parking, thereby improving battery swapping efficiency and accuracy.

[0017] Guiding vehicles into the correct position: The design of the movable guardrail can guide vehicles into the correct battery swapping position, avoiding difficulties or delays in battery swapping caused by incorrect vehicle positioning.

Therefore, they should not be construed as limitations on this application.

[0025] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] 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.

[0028] Example 1 Please see the appendix Figure 1 , 2 5. This embodiment provides a parking platform with movable guardrails, on which two sets of first guardrail sections 2 are correspondingly arranged along the length direction of the parking platform 1; The first guardrail section 2 is connected to a plurality of first driving devices 3, and the plurality of first driving devices 3 are respectively connected to different positions in the length direction of the first guardrail section 2. Several first drive devices 3 can jointly drive the same first guardrail section 2 connected to each other to move toward or away from another first guardrail section 2.

[0029] Specifically, each first guardrail section 2 is preferably connected to two first drive devices 3, which are respectively connected to both ends of the first guardrail section 2, so that the movement of both ends of the first guardrail section 2 can be adjusted respectively.

[0030] Specifically, by adjusting the distance between the two first guardrail sections 2 through the first drive device 3, the "movable width" of the top surface of the parking platform 1 can be changed, which can provide additional safety protection, effectively prevent the vehicle from skidding or falling off the parking platform 1, improve the safety of the battery swapping process, reduce the psychological burden on the driver, make it easier for him to complete the parking operation, and guide the vehicle into the correct battery swapping posture to avoid difficulties or delays in battery swapping caused by the vehicle's incorrect position.

[0031] In addition, to prevent the first guardrail section 2 from causing excessive friction to the vehicle, this embodiment provides two structural configurations for the first guardrail section 2: First structure: See reference Figure 2 , 7 As shown, the first guardrail section 2 includes a first guardrail plate 21 and a plurality of first vertical rollers 22 that are sequentially rolled on the guardrail plate. The axial direction of the first vertical rollers 22 is perpendicular to the laying direction of the first guardrail plate 21. The plurality of rolling first vertical rollers 22 can provide rolling force when the wheel hits the first guardrail section 2, so as to "bounce" the wheel away and avoid friction.

[0032] First structure: See reference Figure 1 , 3 As shown, the first guardrail section 2 includes a first guardrail plate 21 and a plurality of first transverse rollers 23 sequentially rolled on the first guardrail plate 21. The axial direction of the first transverse rollers 23 is parallel to the laying direction of the first guardrail plate 21. Through the plurality of rolling first transverse rollers 23, rolling force can be provided when the wheel hits the first guardrail section 2, so as to "bounce" the wheel away and avoid friction.

[0033] It should be noted that, as Figure 1 , 2 As shown, the parking platform 1 can be composed of two corresponding single-sided bridges, and two first guardrail sections 2 are respectively set on the opposite outer sides of the top of the two single-sided bridges.

[0034] Example 2 Please see the appendix Figure 4 , 5 The difference between this embodiment and Embodiment 1 is that this embodiment provides a structural composition of the first driving device 3: The first driving device 3 includes a first electric telescopic rod 31, a first slider 32, a first slide rail 33, and a first connecting rod 34; The first electric telescopic pole 31 is installed inside the parking platform 1, and the telescopic direction of the first electric telescopic pole 31 is parallel to the width direction of the parking platform 1. The first electric telescopic rod 31 has a first slider 32 installed at its telescopic end; A first slide rail 33 is arranged on one side of the first electric telescopic pole 31, and the arrangement direction of the first slide rail 33 is the same as the telescopic direction of the first electric telescopic pole 31. The first slider 32 is in sliding engagement with the first slide rail 33; A first groove 11 is provided on the top surface of the parking platform 1, and the opening direction of the first groove 11 is adapted to the movement direction of the first slider 32. A first connecting rod 34 is installed on the first slider 32, and the end of the first connecting rod 34 passes through the first groove 11 and connects to the first guardrail part 2.

[0035] Specifically, when the first electric telescopic rod 31 drives the first slider 32 to move on the first slide rail 33, it can drive the first connecting rod 34 to move accordingly, thereby driving the first guardrail part 2 to move accordingly. The entire first drive device 3 is installed inside the parking platform 1, does not affect the top space of the parking platform 1, and can protect the first drive device 3.

[0036] In addition, in order to ensure that the first guardrail part 2 will not continue to move after it has been moved into place (such as movement caused by external force), this embodiment also provides a number of first locking parts 4 inside the parking platform 1, which correspond one-to-one with a number of first driving devices 3. The first locking parts 4 are used to restrict the movement of the first slider 32.

[0037] Specifically, see Figure 5 As shown, the first locking part 4 includes a first electric push rod 41 and a first locking member 42 installed at the output end of the first electric push rod 41; The first electric push rod 41 pushes the first locking member 42 to move closer to or further away from the first slider 32; A first locking member 43 is installed on the side of the first slider 32 facing the first locking member 42, and a plurality of first locking slots 44 are sequentially opened on the first locking member 42 along the moving direction of the first slider 32. The shape of the first slot 44 is adapted to the shape of the first card piece 43.

[0038] Specifically, when the first electric telescopic rod 31 moves the first slider 32 into position, the first electric push rod 41 can push the first locking member 42 to move closer to the first slider 32. When it moves into position, the first locking member 43 will be locked inside one of the first slots 44, and the first slider 32 will not be able to move further. This can effectively prevent the first guardrail 2 from being displaced due to the wheel hitting the first guardrail 2. When it is necessary to change the distance between the two first guardrails 2, the first electric push rod 41 can push the first locking member 42 to move away from the first slider 32, so that the first locking member 43 moves out of the first slot 44, and the first slider 32 can continue to move.

[0039] Example 3 Please see the appendix Figure 1 , 2 The difference between this embodiment and embodiment two is that this embodiment also provides an upper ramp 5 and a lower ramp 6 at both ends of the length direction of the parking platform 1. Two sets of second guardrail sections 7 are installed at the opposite outer edges of the ramp 5.

[0040] Specifically, the upper ramp 5 and the lower ramp 6 facilitate vehicles to enter or exit the top surface of the parking platform 1. In order to ensure that vehicles do not fall off during the movement of the upper ramp 5, a second guardrail 7 is also installed on the upper ramp 5. Of course, a third guardrail (not shown in the attached figure) can also be installed on the lower ramp 6. These are all possible and can further ensure the safety of the vehicle movement process.

[0041] Specifically, the specific structural settings of the second guardrail section 7 and the third guardrail section can also be found in the two structural settings of the first guardrail section 2.

[0042] In addition, to achieve variable distance for the second guardrail section 7, two structural components can be added: First scenario: See below Figure 1 , 6 As shown, the end of the second guardrail 7 away from the first guardrail 2 is hinged to the ramp 5 of the upper platform. The second guardrail section 7 is connected to a second drive device at one end near the first guardrail section 2; and this second drive device can be used in combination (cooperation) with an adjacent first drive device 3. Specifically, the structure of the first drive device 3 has been described in Embodiment 2, see [link / reference]. Figure 6 As shown, a second connecting rod 35 can be added to the first slider 32 adjacent to the second guardrail 7. The first connecting rod 34 and the second connecting rod 35 are located on the left and right sides of the first slider 32, respectively. The first slider 32 is also provided with a sliding hole 36 along its length. The second connecting rod 35 is slidably connected inside the sliding hole 36. An arc-shaped second sliding groove 51 is opened on the upper platform slope 5. The end of the second connecting rod 35 passes through the second sliding groove 51 and connects to the second guardrail 7. This realizes that the first driving device 3 can simultaneously drive the first guardrail 2 and the second guardrail 7 to move, and the second guardrail 7 rotates around the hinge point between itself and the upper platform slope 5.

[0043] Specifically, in this embodiment, the first driving device 3 and the second driving device are essentially the same driving device. Of course, the second driving device can also be set up separately and can be set up in a structure similar to the first driving device 3. These are all feasible structural designs.

[0044] Second scenario: See below Figure 2 ,7 As shown, one end of the second guardrail section 7 is connected to the end of the first guardrail section 2; The other end of the second guardrail 7 is slidably connected to the ramp 5 of the upper platform; Specifically, the structure of the first driving device 3 has been described in Embodiment 2. In this case, the second driving mechanism can also drive the second guardrail 7 to move when it drives the first guardrail 2 to move.

[0045] Specifically, a third slide groove 52 can be opened on the upper ramp 5 along its width direction, and a third connecting rod 71 can be installed at the end of the second guardrail 7, allowing the third connecting rod 71 to slide inside the third slide groove 52. A second push-pull rod (not shown in the attached figure) is set inside the upper ramp along the direction of the third slide groove 52, connecting the third connecting rod 71 to the second push-pull rod. This arrangement allows the second guardrail 7 to move linearly.

[0046] Furthermore, the structure of the second guardrail section 7 in this case is somewhat special, which can be referred to... Figure 7 As shown.

[0047] Example 4 This embodiment provides a parking method, which can be applied to any of the above embodiments, and specifically includes the following steps: S1, before the battery swapping vehicle enters the parking platform 1, the first guardrail 2 is located on the outermost side of the parking platform 1; S2, the identification system inside the battery swapping station identifies the license plate and retrieves the recorded wheel width of the vehicle; S3, the control system controls several first drive devices 3 to move the first guardrail 2 toward the inside of the parking platform 1 according to the retrieved wheel width distance; S4, when the spacing of the first guardrail section 2 is equal to the sum of the retrieved wheel width and the threshold, the first drive device 3 stops driving the first guardrail section 2 to move inward toward the parking platform 1, and the first locking part 4 fixes the first clip 43.

[0048] 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.
