Abstract
Description
Technical Field
[0001] This application is generally related to chassis and vehicles, and more particularly to retractable chassis and vehicles. Background Technology
[0002] Light commercial vehicles (LCVs) are widely used for transporting goods. However, there are some problems with the application of LCVs. For example, in congested urban areas and narrow streets, it can be difficult for LCVs to navigate or find suitable parking spaces. Furthermore, the space occupied by an LCV remains constant regardless of the load. Additionally, when an LCV is not fully loaded, some of the installed air conditioning or refrigeration equipment is wasted. Moreover, even when an LCV is stationary, it still requires a certain amount of parking space, resulting in high parking expenses due to real estate space requirements. Furthermore, variable-sized LCVs are needed to meet diverse business needs, thus requiring different maintenance and staff training for different sized LCVs. Summary of the Invention
[0003] In view of the above problems, this application provides a retractable chassis and a vehicle. The retractable chassis includes a mid-frame, a first frame, a second frame, and at least one drive module. The mid-frame has a first side and a second side opposite to each other. The first frame is movably disposed on the first side of the mid-frame. The second frame is movably disposed on the second side of the mid-frame. The drive module is disposed on at least one of the mid-frame, the first frame, and the second frame. The at least one drive module is adapted to actuate at least one of the first frame and the second frame relative to the mid-frame.
[0004] The retractable vehicle includes a mid-frame, a first frame, a second frame, at least one drive module, a first body, a second body, and a mid-body. The first body is disposed on the first frame. The second body is disposed on the second frame. The mid-body is located above the mid-frame and coupled to the first and second body.
[0005] In summary, this application provides a scalable chassis and vehicle. The chassis and vehicle offer flexibility to extend and retract based on specific needs. For example, when a larger storage capacity is desired, it may need to be extended, and when a smaller vehicle footprint is desired, it may need to be retracted. In conclusion, this application provides a scalable chassis and vehicle that offers dynamic adaptability to accommodate different space requirements, thereby enabling it to extend to increase storage capacity and retract to optimize space.

[0026] Please refer to Figure 1 as well as Figure 2The retractable chassis 100 includes a middle frame 130, a first frame 110, a second frame 120, and at least one drive module 140. The middle frame 130 has a first side 131 and a second side 132 opposite to each other. The first frame 110 is movably disposed on the first side 131 of the middle frame 130. The second frame 120 is movably disposed on the second side 132 of the middle frame 130. The retractable chassis 100 is retractable, and its total length can be maintained in various dimensions as needed, providing a range of adaptable lengths to meet diverse requirements. The first frame 110 and the second frame 120 can be congruent or diverse, and the size and dimensions of the middle frame 130 can be freely selected, contributing to applications with different spatial considerations.
[0027] In some embodiments, the middle frame portion 130 includes a first sliding portion 133 located at a first end 131 and a second sliding portion 134 located at a second end 132. The first frame portion 110 includes a first slider 111 slidably coupled to the first sliding portion 133, and the second frame portion 120 includes a second slider 121 slidably coupled to the second sliding portion 134. Figure 1 as well as Figure 2 In the illustrated embodiment, the first frame portion 110 is provided with two sliders 111, and the second frame portion 120 is provided with two sliders 121. However, it should be understood that the consistency of the number and arrangement of the first sliders 111 and the second sliders 121 is not an absolute requirement. For example, there may be one first slider 111 and three second sliders 121, and the arrangement of the first sliders 111 and the second sliders 121 does not need to be aligned with each other or symmetrical. Similarly, the number and arrangement of the first sliding portion 133 and the second sliding portion 134 will be set according to the corresponding first sliders 111 and second sliders 121.
[0028] The at least one drive module 140 is disposed on at least one of the middle frame portion 130, the first frame portion 110, and the second frame portion 120, and the at least one drive module 140 is adapted to actuate at least one of the first frame portion 110 and the second frame portion 120 relative to the middle frame portion 130. That is, the at least one drive module 140 is adapted to actuate the first frame portion 110 and / or the second frame portion 120.
[0029] For example, Yu Figure 1In this configuration, a first drive module 141 is disposed on the first frame portion 110 to independently actuate the first frame portion 110 relative to the middle frame portion 130, and a second drive module 142 is disposed on the second frame portion 120 to independently actuate the second frame portion 120 relative to the middle frame portion 130. However, the number and placement of the drive modules 140 are not limited thereto. For example, the drive modules 140 can be implemented using a coordinated configuration of racks and pinions (not shown), which can be disposed between the first frame portion 110 and the middle frame portion 130, and between the second frame portion 120 and the middle frame portion 130. Furthermore, the drive modules 140 can be implemented to drive locking and releasing mechanisms 112 / 122 (see... Figure 3 as well as Figure 4 (To be explained later).
[0030] As another example, the drive module 140 can operate as a power source (e.g., a hub motor) for the tires of the retractable chassis 100. When the movement between the first frame portion 110 and the middle frame portion 130 is not locked, a tire on either side of the retractable chassis 100 can cause the first frame portion 110 to move relative to the middle frame portion 130, thus achieving chassis retraction. Similarly, when the movement between the second frame portion 120 and the middle frame portion 130 is not locked, a tire on either side of the retractable chassis 100 can cause the second frame portion 120 to move relative to the middle frame portion 130, thus achieving chassis retraction.
[0031] Specifically, the first frame portion 110 includes a first proximal end 114 and a first distal end 113, and the second frame portion 120 includes a second proximal end 124 and a second distal end 123. In some embodiments, the first proximal end 114 is movably disposed on a first side 131 of the middle frame portion 110 via a first slider 111 and a first sliding portion 133; and the second proximal end 124 is movably disposed on a second side 132 of the middle frame portion 130 via a second slider 121 and a second sliding portion 134. In response to at least one of the first distal end 113 and the second distal end 123 being actuated away from the middle frame portion 130 (i.e., the first distal end 113 and / or the second distal end 123 being actuated away from the middle frame portion 130), the length of the retractable chassis 100 increases. In response to at least one of the first distal end 113 and the second distal end 123 being actuated to approach the mid-frame portion 130 (i.e., the first distal end 113 and / or the second distal end 123 being actuated to approach the mid-frame portion 130), the length of the retractable chassis 100 is reduced.
[0032] Please refer to Figure 3 as well as Figure 4In some embodiments, the retractable chassis 100 further includes a first locking and releasing mechanism 112 and a second locking and releasing mechanism 122. The first locking and releasing mechanism 112 is disposed between the first frame portion 110 and the middle frame portion 130 and configured to releasably secure movement of the first frame portion 110 relative to the middle frame portion 130. The second locking and releasing mechanism 122 is disposed between the second frame portion 120 and the middle frame portion 130 and configured to releasably secure movement of the second frame portion 120 relative to the middle frame portion 130. In some embodiments, the first locking and releasing mechanism 112 is provided between the first sliding portion 133 and the first sliding member 111, and the second locking and releasing mechanism 122 is provided between the second sliding portion 134 and the second sliding member 121.
[0033] It should be understood that the number of first locking and releasing mechanisms 112 depends on the number of first sliders 111 and first sliding portions 133, and the number of second locking and releasing mechanisms 122 depends on the number of second sliders 121 and second sliding portions 134. The number of first locking and releasing mechanisms 112 may be the same as or different from the number of first sliders 111 and first sliding portions 133, and the number of second locking and releasing mechanisms 122 may be the same as or different from the number of second sliders 121 and second sliding portions 134. For example, it is possible to have a smaller number of locking and releasing mechanisms compared to the number of sliders, as long as the locking and releasing requirements are met.
[0034] As mentioned above, the first locking and releasing mechanism 112 and the second locking and releasing mechanism 121 can be driven by the drive module 140 to actuate the first frame portion 110 and the second frame portion 120 relative to the middle frame portion 130. That is, the locking and releasing mechanism 120 and the drive module 140 can be integrated. The number of drive modules 140 can be the same as or different from the sum of the number of the first locking and releasing mechanisms 112 and the number of the second locking and releasing mechanisms 122. For example, there can be fewer drive modules 140 than the number of locking and releasing mechanisms, as long as the driving requirements are met.
[0035] Specifically, in some embodiments, each of the first locking and releasing mechanism 112 and the second locking and releasing mechanism 122 includes a rack 112a / 122a and a pinion 112b / 122b that is gear-coupled to the rack 112a / 122a.
[0036] Please refer to Figure 5The retractable vehicle 200 includes a mid-frame portion 130, a first frame portion 110, a second frame portion 120, a drive module 140, a first vehicle body portion 210, a second vehicle body portion 220, and a middle vehicle body portion 230. The first vehicle body portion 210 is disposed on the first frame portion 110. The second vehicle body portion 220 is disposed on the second frame portion 120. The middle vehicle body portion 230 is located above the mid-frame portion 130 and coupled to the first vehicle body portion 210 and the second vehicle body portion 220. The middle vehicle body portion 230 may or may not be disposed on the mid-frame portion 130. In different embodiments, the retractable chassis 110 of the various foregoing embodiments may be combined with the first vehicle body portion 210, the second vehicle body portion 220, and the middle vehicle body portion 230 to form the retractable vehicle 200.
[0037] At Figure 5 In the illustrated embodiment, the first vehicle body portion 210 and the second vehicle body portion 220 are the rear and front portions of the retractable vehicle 200, respectively. However, it should be understood that this application is not limited to this exact configuration. Those skilled in the art will understand that the first vehicle body portion 210 can serve as the front portion, and conversely, the second vehicle body portion 220 can serve as the rear portion.
[0038] In addition, Figure 5 In the illustrated embodiment, the middle vehicle body 230 is located below both the first vehicle body 210 and the second vehicle body 220, and the middle vehicle body 230 is at least partially covered by the first vehicle body 210. However, this application is not limited thereto. Those skilled in the art will understand that the middle vehicle body 230 may also be located above the first vehicle body 210 and the second vehicle body 220, and the first vehicle body 210 may be partially covered by the middle vehicle body 230. Furthermore, in Figure 5 In the illustrated embodiment, the middle vehicle body portion 230 is connected to the second vehicle body portion 220 and overlaps with the first vehicle body portion 210. Those skilled in the art will understand that the middle vehicle body portion 230 may alternatively be connected to the first vehicle body portion 210 and overlap with the second vehicle body portion 220.
[0039] Please refer to Figure 5 as well as Figure 8 In response to at least one of the first distal end 113 and the second distal end 123 being actuated away from the mid-frame portion 130, the length of the retractable vehicle 200 increases. In response to at least one of the first distal end 113 and the second distal end 123 being actuated towards the mid-frame portion 130, the length of the retractable vehicle 200 decreases. Since the retractable vehicle 200 incorporates the retractable chassis 100 from any of the above embodiments for retraction, the total length of the retractable vehicle 200 can also be maintained in various dimensions as needed.
[0040] In some embodiments, in response to at least one of the first distal end 113 and the second distal end 123 being actuated away from the middle frame portion 130, the middle vehicle body portion 230 overlaps less with the first vehicle body portion 210; and in response to at least one of the first distal end 113 and the second distal end 123 being actuated towards the middle frame portion 130, the middle vehicle body portion 230 overlaps more with the first vehicle body portion 210. For example, comparing Figure 5 as well as Figure 8 It can be seen that the middle car body 230 and the first car body 210 are at Figure 5 There is a lot of overlap in the middle and at Figure 8 The overlap is relatively small. In short, the degree of overlap between the middle body portion 230 and the first body portion 210 is changed by adjusting the position of the first and second far ends 113 and 123 relative to the middle frame portion 130.
[0041] In some embodiments, one of the first body portion 210 and the second body portion 220 includes an enclosed compartment, while the other of the first body portion 210 and the second body portion 220, together with the middle body portion 230, forms a cargo bed, such that the retractable vehicle 200 forms a pickup truck (not shown). In some embodiments, each of the first body portion 210, the second body portion 220, and the middle body portion 230 may be enclosed, semi-open, or open.
[0042] Please refer to Figures 5 to 7 In some embodiments, a first sealing strip 211 may be provided at the edge of the first vehicle body portion 210 and between the middle vehicle body portion 230 and the first vehicle body portion 210, with the middle vehicle body portion 230 and the first vehicle body portion 210 coupled to each other via the first sealing strip 211. Furthermore, a first intermediate sealing strip 231 may be provided at the edge of the middle vehicle body portion 230 and between the middle vehicle body portion 230 and the first vehicle body portion 210, with the middle vehicle body portion 230 and the first vehicle body portion 210 coupled to each other via the first intermediate sealing strip 231. The first sealing strip 211 and the first intermediate sealing strip 231 are used to prevent water or moisture from seeping into the gap between the first vehicle body portion 210 and the middle vehicle body portion 230.
[0043] Furthermore, a first groove 241 may be provided on the middle body portion 230, located between the first sealing strip 211 and the first intermediate sealing strip 231. This configuration allows water or moisture that may enter the gap between the first body portion 210 and the middle body portion 230 through the first sealing strip 211 and / or the first intermediate sealing strip 231. Water or moisture can be drained through the first groove 241. Specifically, in Figures 5 to 7In the illustrated embodiment, because the middle vehicle body 230 is located below the first vehicle body 210, a groove is provided on the middle vehicle body 230. Those skilled in the art will understand that in an alternative embodiment (not shown) where the middle vehicle body 230 is located above the first vehicle body 210, a first groove 241 will be provided on the first vehicle body 210.
[0044] Please refer to Figures 9 to 12 In some embodiments, with Figures 5 to 8 Unlike the previous embodiment shown (in which the middle vehicle body 230 is connected to the second vehicle body 220), the middle vehicle body 230 is a separate vehicle body that is not connected to either the first vehicle body 210 or the second vehicle body 220.
[0045] Similar to previous embodiments, in some embodiments, the middle vehicle body portion 230 may be located below or above the first vehicle body portion 210 and the second vehicle body portion 220. Therefore, the middle vehicle body portion 230 may be at least partially covered by the first vehicle body portion 210 and the second vehicle body portion 220, or the middle vehicle body portion 230 may partially cover the first vehicle body portion 210 and the second vehicle body portion 220. It should be understood that the overlap area between the first vehicle body portion 210 and the middle vehicle body portion 230 may be the same as or different from the overlap area between the second vehicle body portion 220 and the middle vehicle body portion 230. In short, the middle vehicle body portion 230 can be located above or below the first and second vehicle body portions 210 and 220, resulting in varying degrees of overlap; thereby, the middle vehicle body portion 230 may be partially hidden by or partially covered by the first and second vehicle body portions 210 and 220.
[0046] Similar to previous embodiments, in some embodiments, in response to at least one of the first distal end 113 and the second distal end 123 being actuated to move relative to the mid-frame portion 130, the length of the retractable vehicle 200 increases or decreases, and the retractable vehicle 200 overlaps more or less with the first body portion 210 and the second body portion 220. Furthermore, the total length of the retractable vehicle 200 can be maintained in various dimensions as needed.
[0047] In some embodiments, sealing strips may also be provided to prevent water or moisture from entering the gap between the first body section 210 and the middle body section 230, and the gap between the second body section 220 and the middle body section 230. For example... Figure 10 as well as Figure 11As shown, in addition to the first sealing strip 211 and the first intermediate sealing strip 231, a second sealing strip 221 may be provided at the edge of the second vehicle body portion 220 and between the intermediate vehicle body portion 230 and the second vehicle body portion 220, and the intermediate vehicle body portion 230 and the second vehicle body portion 220 are coupled to each other through the second sealing strip 221. Furthermore, a second intermediate sealing strip 232 may be provided at the edge of the intermediate vehicle body portion 230 and between the intermediate vehicle body portion 230 and the second vehicle body portion 220, and the intermediate vehicle body portion 230 and the second vehicle body portion 220 are coupled to each other through the second intermediate sealing strip 232.
[0048] In some embodiments, the groove may also be provided to drain water or moisture from the gap between the first body section 210 and the middle body section 230 and the gap between the second body section 220 and the middle body section 230. For example... Figure 11 As shown, in addition to the first groove 241, a second groove 242 may be provided on the middle vehicle body portion 230, located between the second sealing strip 221 and the second middle sealing strip 232. Those skilled in the art will understand that in an alternative embodiment (not shown) where the middle vehicle body portion 230 is located on the first vehicle body portion 210 and the second vehicle body portion 220, the first groove 241 and the second groove 242 will be provided on the first vehicle body portion 210 and the second vehicle body portion, respectively.
[0049] Please refer to Figures 13 to 18 In some embodiments, the middle body portion 230 may connect the first body portion 210 and the second body portion 220 and is made of a flexible material. For example, the middle body portion may allow folding (e.g., Figures 13 to 18 As shown in the figure), or it may be elastic (not shown). In response to at least one of the first frame portion 110 and the second frame portion 120 being actuated to move relative to the middle frame portion 130, the middle vehicle body portion 230 extends or retracts.
[0050] Please refer to Figure 19 as well as Figure 20 In some embodiments, the central body portion 230 may comprise multiple portions and be nested. That is, a portion of the central body portion 230 can slide out (extend) from another portion of the central body portion 230, increasing the length of the central body portion 230; conversely, a portion of the central body portion 230 can slide into another portion of the central body portion 230 (contract), shortening the length of the central body portion 230. The nested configuration of the central body portion 230 extends or contracts in response to at least one of the first frame portion 110 and the second frame portion 120 being actuated to move relative to the central frame portion 130.
[0051] In summary, this application provides a scalable chassis and vehicle. The chassis and vehicle offer flexibility to scale based on specific needs. For example, when a larger storage capacity is desired, it may need to extend, and when a smaller vehicle footprint is desired, it may need to retract. In conclusion, this application provides an adaptive chassis and vehicle system that can scale based on specific space requirements (e.g., accommodating larger storage or occupying less space).
