Description

TECHNICAL FIELD

[0001] The present invention relates to a chassis and a vehicle, and particularly to a telescopic chassis and a vehicle. BACKGROUND ART

[0002] Light commercial vehicles (LCVs) are generally used for transporting cargo. However, several problems exist in the application of LCVs. For example, in congested urban areas or narrow roads, it may be difficult to maneuver an LCV and find a suitable parking space. In addition, the space occupied by the LCV remains unchanged regardless of the amount of load. Furthermore, when the LCV is not fully loaded, part of the air conditioning and refrigeration of the container is wasted. Moreover, the LCV requires the same space for parking even when not in use, and the parking cost of the LCV is high due to the space required for real estate. In addition, to meet diverse business needs, it is necessary to have LCVs of different sizes available, which requires various maintenance and staff training for LCVs of different sizes. SUMMARY OF INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION

[0003] In view of the above-described problems, an object of the present invention is to provide a telescopic chassis and a vehicle. MEANS FOR SOLVING THE PROBLEMS

[0004] The telescopic chassis of the present invention comprises an intermediate frame section, a first frame section, a second frame section, and at least one drive module. The intermediate frame section has a first side and a second side facing each other. The first frame section is movably positioned on the first side of the intermediate frame section. The second frame section is movably positioned on the second side of the intermediate frame section. The drive module is positioned on at least one of the intermediate frame section, the first frame section, and the second frame section. The at least one drive module is configured to actuate the first frame section and at least one of the second frame section, moving them relative to the intermediate frame section.

[0005] The telescopic vehicle comprises an intermediate frame section, a first frame section, a second frame section, at least one drive module, a first body section, a second body section, and an intermediate body section. The first body section is positioned on the first frame section. The second body section is positioned on the second frame section. The intermediate body section is located above the intermediate frame section and is coupled to the first and second body sections. [Effects of the Invention]

[0006] As described above, the present invention provides a retractable chassis and vehicle. The chassis and vehicle offer flexibility to expand and contract based on specific needs. For example, expansion may be necessary when a larger storage capacity is desired, and contraction may be necessary when a smaller space occupied by the vehicle is desired. In summary, the present invention provides a retractable chassis and vehicle that offers dynamic adaptability to meet diverse spatial requirements, enabling expansion to increase storage capacity and contraction for space optimization.

[0009] <Example 1> Refer to Figures 1 and 2. The telescopic chassis 100 comprises an intermediate frame section 130, a first frame section 110, a second frame section 120, and at least one drive module 140. The intermediate frame section 130 comprises a first side 131 and a second side 132 facing each other. The first frame section 110 is movably positioned on the first side 131 of the intermediate frame section 130. The second frame section 120 is movably positioned on the second side 132 of the intermediate frame section 130. The telescopic chassis 100 is telescopic, and the overall length of the telescopic chassis 100 may be maintained at various dimensions as needed, and is adjustable to various lengths to accommodate diverse requirements. The first frame section 110 and the second frame section 120 may be identical or different, and the size and dimensions of the intermediate frame section 130 can be freely selected to serve applications with various spatial considerations.

[0010] In some embodiments, the intermediate frame portion 130 comprises a first sliding portion 133 on the first side 131 and a second sliding portion 134 on the second side 132. The first frame portion 110 comprises a first sliding element 111 slidably coupled to the first sliding portion 133, and the second frame portion 120 comprises a second sliding element 121 slidably coupled to the second sliding portion 134. In the embodiments shown in Figures 1 and 2, the first frame portion 110 comprises two sliding elements 111, and the second frame portion 120 comprises two sliding elements 121. However, uniformity in the number and arrangement of the first sliding elements 111 and the second sliding elements 121 is not considered an absolute requirement. For example, there may be one first sliding element 111 and three second sliding elements 121, and the arrangement of the first sliding element 111 and the second sliding elements 121 does not need to coincide with or be symmetrical to each other. Similarly, the number and arrangement of the first sliding parts 133 and the second sliding parts 134 are determined based on the corresponding first sliding elements 111 and the second sliding elements 121.

[0011] The at least one drive module 140 is disposed on at least one of the intermediate frame part 130, the first frame part 110, and the second frame part 130, and the at least one drive module 140 is configured to actuate at least one of the first frame part 110 and the second frame part 120 to move relative to the intermediate frame part 130. That is, the at least one drive module 140 is configured to actuate the first frame part 110 and / or the second frame part 120.

[0012] For example, in FIG. 1, the first drive module 141 is disposed on the first frame part 110, and independently actuates the first frame part 110 to move it relative to the intermediate frame part 130. The second drive module 142 is disposed on the second frame part 120, and independently actuates the second frame part 120 to move it relative to the intermediate frame part 130. However, the number and arrangement of the drive modules 140 are not limited thereto. For example, the drive module 140 may be implemented using a rack and pinion interlocking mechanism (not shown) disposed between the first frame part 110 and the intermediate frame part 130, and between the second frame part 120 and the intermediate frame part 130. Further, the drive module 140 may be implemented to drive the lock / unlock mechanisms 112 / 122 (refer to FIG. 3 and FIG. 4, described later).

[0013] As another example, the drive module 140 may function as a power source for the wheels of the retractable chassis 100, such as an in-wheel motor. When the movement between the first frame part 110 and the intermediate frame part 130 is not locked, the wheels on both sides of the retractable chassis 100 move the first frame part 110 relative to the intermediate frame part 130, so as to achieve the extension and retraction of the chassis. Similarly, when the movement between the second frame part 120 and the intermediate frame part 130 is not locked, the wheels on both sides of the retractable chassis 100 move the second frame part 120 relative to the intermediate frame part 130, so as to achieve the extension and retraction of the chassis.

[0014] Specifically, the first frame portion 110 comprises a first proximal end 114 and a first distal end 113, and the second frame portion 120 comprises a second proximal end 124 and a second distal end 123. In some embodiments, the first proximal end 114 is movably positioned on the first side 131 of the intermediate frame portion 110 through a first sliding element 111 and a first sliding portion 133, and the second proximal end 124 is movably positioned on the second side 132 of the intermediate frame portion 130 through a second sliding element 121 and a second sliding portion 134. When at least one of the first distal end 113 and the second distal end 123 is actuated and moves away from the intermediate frame 130 (i.e., the first distal end 113 and / or the second distal end 123 are actuated and move away from the intermediate frame 130), the length of the telescopic chassis 100 is extended. When at least one of the first distal end 113 and the second distal end 123 is actuated and moves toward the intermediate frame 130 (i.e., the first distal end 113 and / or the second distal end 123 are actuated and move toward the intermediate frame 130), the length of the telescopic chassis 100 is shortened.

[0015] Refer to Figures 3 and 4. In some embodiments, the telescopic chassis 100 further comprises a first lock / unlock mechanism 112 and a second lock / unlock mechanism 122. The first lock / unlock mechanism 112 is located between the first frame portion 110 and the intermediate frame portion 130 and is configured to releasably fix the movement of the first frame portion 110 relative to the intermediate frame portion 130. The second lock / unlock mechanism 122 is located between the second frame portion 120 and the intermediate frame portion 130 and is configured to releasably fix the movement of the second frame portion 120 relative to the intermediate frame portion 130. In some embodiments, the first lock / unlock mechanism 112 is provided between the first sliding portion 133 and the first sliding element 111, and the second lock / unlock mechanism 122 is provided between the second sliding portion 134 and the second sliding element 121.

[0016] The number of first lock / unlock mechanisms 112 depends on the number of first sliding elements 111 and first sliding parts 133, and the number of second lock / unlock mechanisms 122 depends on the number of second sliding elements 121 and second sliding parts 134. The number of first lock / unlock mechanisms 112 may be the same as or different from the number of first sliding elements 111 and first sliding parts 133, and the number of second lock / unlock mechanisms 122 may be the same as or different from the number of second sliding elements 121 and second sliding parts 134. For example, there may be fewer lock / unlock mechanisms than sliding elements, as long as the locking and unlocking requirements are met.

[0017] As described above, the first lock / unlock mechanism 112 and the second lock / unlock mechanism 121 may each be driven by a drive module 140 to actuate the first frame section 110 and the second frame section 120 and move them relative to the intermediate frame section 130, respectively. In other words, the lock / unlock mechanism 120 and the drive module 140 may be integrated. The number of drive modules 140 may be the same as or different from the sum of the number of first lock / unlock mechanisms 112 and the number of second lock / unlock mechanisms 122. For example, there may be fewer drive modules 140 than lock / unlock mechanisms, as long as the driving requirements are met.

[0018] Specifically, in some embodiments, each first lock / unlock mechanism 112 and each second lock / unlock mechanism 122 comprises a rack gear 112a / 122a and a pinion gear 112b / 122b meshed with the rack gear 112a / 122a.

[0019] <Example 2> Refer to Figure 5. The telescopic vehicle 200 comprises an intermediate frame section 130, a first frame section 110, a second frame section 120, a drive module 140, a first body section 210, a second body section 220, and an intermediate body section 230. The first body section 210 is positioned on the first frame section 110. The second body section 220 is positioned on the second frame section 120. The intermediate body section 230 is located above the intermediate frame section 130 and is coupled to the first body section 210 and the second body section 220. The intermediate body section 230 may be positioned on or off the intermediate frame section 130. In a different embodiment, the telescopic chassis 110 of the various embodiments described above can be combined with a first body section 210, a second body section 220, and an intermediate body section 230 to form a telescopic vehicle 200.

[0020] In the embodiment shown in Figure 5, the first body section 210 and the second body section 220 are the rear and front sections of the telescopic vehicle 200, respectively. However, it is important to note that the present invention is not limited to this exact configuration. Those skilled in the art will understand that the first body section 210 may function as the front section, and conversely, the second body section 220 may function as the rear section.

[0021] Furthermore, in the embodiment shown in Figure 5, the intermediate body section 230 is positioned below both the first body section 210 and the second body section 220, and the intermediate body section 230 is at least partially covered by the first body section 210. However, the present invention is not limited thereto. Those skilled in the art will understand that the intermediate body section 230 may be positioned above the first body section 210 and the second body section 220, and the first body section 210 may be at least partially covered by the intermediate body section 230. Moreover, in the embodiment shown in Figure 5, the intermediate body section 230 is connected to the second body section 220 and overlaps with the first body section 210. Those skilled in the art will understand that the intermediate body section 230 may instead be connected to the first body section 210 and overlap with the second body section 220.

[0022] Refer to Figures 5 and 8. When at least one of the first distal end 113 and the second distal end 123 is actuated and moves away from the intermediate frame 130, the length of the telescopic vehicle 200 is extended. When at least one of the first distal end 113 and the second distal end 123 is actuated and moves toward the intermediate frame 130, the length of the telescopic vehicle 200 is shortened. The telescopic vehicle 200 comprises the telescopic chassis 100 in any of the embodiments described above for extension and retraction, and the overall length of the telescopic vehicle 200 may also be maintained at various dimensions as needed.

[0023] In some embodiments, when at least one of the first distal end 113 and the second distal end 123 is actuated and moves away from the intermediate frame 130, the overlap between the intermediate body 230 and the first body 210 decreases. Conversely, when at least one of the first distal end 113 and the second distal end 123 is actuated and moves toward the intermediate frame 130, the overlap between the intermediate body 230 and the first body 210 increases. For example, comparing Figure 5 and Figure 8, the overlap between the intermediate body 230 and the first body 210 is greater in Figure 5 and smaller in Figure 8. In other words, by adjusting the positions of the first distal end 113 and the second distal end 123 relative to the intermediate frame 130, various degrees of overlap between the intermediate body 230 and the first body 210 can be obtained.

[0024] In some embodiments, either the first body section 210 or the second body section 220 is equipped with a closed cabin, and the other of the first body section 210 or the second body section 220 is equipped with a cargo bed with an intermediate body section 230, thereby forming a pickup truck (not shown) for the telescopic vehicle 200. In some embodiments, each of the first body section 210, the second body section 220, and the intermediate body section 230 may be closed, semi-closed, or open.

[0025] Refer to Figures 5 to 7. In some embodiments, the first seal strip 211 may be installed at the end of the first body section 210 and between the intermediate body section 230 and the first body section 210, so that the intermediate body section 230 and the first body section 210 are connected to each other via the first seal strip 211. In addition, the first intermediate seal strip 231 may be installed at the end of the intermediate body section 230 and between the intermediate body section 230 and the first body section 210, so that the intermediate body section 230 and the first body section 210 are connected to each other via the first intermediate seal strip 231. The purpose of the first seal strip 211 and the first intermediate seal strip 231 is to prevent water and moisture from entering the gap between the first body section 210 and the intermediate body section 230.

[0026] Furthermore, a first groove 241 may be provided on the intermediate body section 230, positioned between the first seal strip 211 and the first intermediate seal strip 231. This arrangement allows for the discharge of water and moisture that may enter the gap between the first body section 210 and the intermediate body section 230 via the first seal strip 211 and / or the first intermediate seal strip 231. The water and moisture can be discharged through the first groove 241. Specifically, in the embodiments shown in Figures 5 to 7, the groove is provided on the intermediate body section 230 because the intermediate body section 230 is below the first body section 210. Those skilled in the art will understand that in other embodiments (not shown) where the intermediate body section 230 is above the first body section 210, the first groove 241 is provided on the first body section 210.

[0027] <Example 3> Refer to Figures 9 to 12. In some embodiments, unlike the embodiments shown in Figures 5 to 8 above in which the intermediate body section 230 is connected to the second body section 220, the intermediate body section 230 is a separate body that is not connected to either the first body section 210 or the second body section 220.

[0028] Similar to the embodiments described above, in some embodiments, the intermediate body section 230 may be located below or above the first body section 210 and the second body section 220. Thus, the intermediate body section 230 may be at least partially covered by the first body section 210 and the second body section 220, or it may partially cover the first body section 210 and the second body section 220. It should be understood that the overlapping area between the first body section 210 and the intermediate body section 230 may be the same as or different from the overlapping area between the second body section 220 and the intermediate body section 230. In other words, the intermediate body section 230 may be located above or below the first body section 210 and the second body section 220, with varying degrees of overlap. Therefore, the intermediate car body section 230 can be partially concealed by the first car body section 210 and the second car body section 220, or it can partially cover the first car body section 210 and the second car body section 220.

[0029] Similar to the embodiments described above, in some embodiments, when at least one of the first distal end 113 and the second distal end 123 is actuated and moved relative to the intermediate frame 130, the length of the telescopic vehicle 200 is extended or shortened, and the telescopic vehicle 200 more or less overlaps with the first body 210 and the second body 220. The overall length of the telescopic vehicle 200 may also be maintained at various dimensions as needed.

[0030] In some embodiments, seal strips may be installed to prevent water and moisture from entering the gaps between the first body section 210 and the intermediate body section 230, and between the second body section 220 and the third body section 230. As shown in Figures 10 and 11, in addition to the first seal strip 211 and the first intermediate seal strip 231, a second seal strip 221 may be installed at the end of the second body section 220 and between the intermediate body section 230 and the second body section 220, so that the intermediate body section 230o and the second body section 220 are connected to each other via the second seal strip 221. Alternatively, a second intermediate seal strip 232 may be installed at the end of the intermediate body section 230 and between the intermediate body section 230 and the second body section 220, so that the intermediate body section 230 and the second body section 220 are connected to each other via the second intermediate seal strip 232.

[0031] In some embodiments, grooves may be provided to drain water and moisture from the gaps between the first body section 210 and the intermediate body section 230, and between the second body section 220 and the intermediate body section 230. As shown in Figure 11, in addition to the first groove 241, a second groove 242 may be provided on the intermediate body section 230, positioned between the second seal strip 221 and the second intermediate seal strip 232. Those skilled in the art will understand that in other embodiments (not shown) where the intermediate body section 230 is located above the first body section 210 and the second body section 220, the first groove 241 and the second groove 242 are provided on the first body section 210 and the second body section, respectively.

[0032] <Example 4> Refer to Figures 13 to 18. In some embodiments, the intermediate body section 230 may be connected to the first body section 210 and the second body section 220 and may be made of a flexible material. For example, the intermediate body section may be foldable (as shown in Figures 13 to 18) or elastic (not shown). When at least one of the first frame section 110 and the second frame section 120 is actuated and moves relative to the intermediate frame section 130, the intermediate body section 230 extends and retracts.

[0033] <Example 5> Refer to Figures 19 and 20. In some embodiments, the intermediate car body 230 may include multiple parts and is extendable. That is, a part of the intermediate car body 230 can be slid out (extended) from the other parts of the intermediate car body 230 to extend its length. Conversely, a part of the intermediate car body 230 can be slid into (stored) within the other parts of the intermediate car body 230 to shorten its length. When at least one of the first frame part 110 and the second frame part 120 is actuated and moves relative to the intermediate frame part 130, the extendable structure of the intermediate car body 230 extends or retracts.

[0034] As described above, the present invention provides an expandable chassis and vehicle. The chassis and vehicle offer flexibility to expand and contract based on specific needs. For example, expansion may be necessary when a larger storage capacity is desired, and contraction may be necessary when a smaller space occupied by the vehicle is desired. In summary, the present invention provides an expandable and adaptive chassis and vehicle system that can accommodate larger storage capacities or reduce occupied space based on specific spatial needs.
