[0002] A suitcase, also known as a travel case or rolling case, is a box carried when traveling to store belongings; it is a type of luggage. Suitcases are typically used to store clothing, personal care items, and souvenirs needed for a trip. Early suitcases were made of wood or other heavy materials, but with the popularization of air travel, suitcases have become made of lighter, more durable materials such as hard plastic or fabric.

[0003] The utility model patent with patent number CN220859609U discloses an electric suitcase, belonging to the field of suitcases. It includes a suitcase body, a battery, a controller, a slide rail disposed inside the suitcase body, a telescopic rod mounted on the slide rail and protruding outside the suitcase body that can slide along the slide rail, and a driver for driving the telescopic rod to slide. The bottom of the telescopic rod is provided with a rack, and the output end of the driver is provided with a drive gear adapted to the rack. The driver drives the rack to move laterally by rotating forward and backward, and drives the telescopic rod to extend and retract.

[0004] In the aforementioned patent, the battery is detachably installed in a battery slot. This design allows users to easily remove and replace the battery when it is depleted or damaged, greatly improving user convenience. Most traditional installations rely on screws and knobs for connection, making disassembly rather inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a multifunctional luggage bag to address the shortcomings of the existing technology.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A multifunctional suitcase includes a suitcase body, a support base installed at the bottom of the suitcase body, a pull rod module provided in the suitcase body, a cavity for storing items formed in the suitcase body, and a side door hinged to one side wall of the suitcase body and communicating with the cavity.

[0008] The support base is equipped with a power supply module, which includes a battery bracket detachably mounted on the support base. The battery bracket has a power cavity, and a power battery is detachably mounted in the power cavity. The power battery is fitted with a battery casing, and an internal compression spring is provided inside the power cavity. The internal compression spring can cause the battery casing, in which the power battery is mounted, to elastically pop outward. The battery casing has a battery locking groove, and the battery bracket is provided with an elastic locking structure that engages with the battery locking groove.

[0009] The support base is provided with a foot pedal module that can be telescopically supported; the foot pedal module includes a foot pedal mounting groove formed in the support base, a foot pedal bracket installed in the foot pedal mounting groove, a sliding cavity formed along the length direction of the foot pedal bracket, an elastically extended support body slidably installed in the sliding cavity, and a press-type elastic self-locking mechanism and a sliding guide structure are provided between the sliding cavity and the support body.

[0010] Therefore, the support base is equipped with a power wheel module.

[0011] The beneficial effects of this utility model are as follows: When unlocking is required, the battery casing will pop out of the power chamber under the elastic drive of the internal compression spring, thereby realizing the removal of the battery; the installation and removal of the power battery can be realized without the use of tools and without the need for screw connection, and the whole process of installation and removal is very convenient. When the power battery is low on power, it can be removed for charging, which enhances its practicality.

[0056] The present invention will now be described in detail with reference to the accompanying drawings.

[0057] like Figure 1-14As shown, a multifunctional suitcase includes a suitcase body 1, a support base 10 installed at the bottom of the suitcase body 1, a pull rod module 101 provided in the suitcase body 1, a cavity for storing items formed in the suitcase body 1, and a side door 109 hinged to one side wall of the suitcase body 1 and communicating with the cavity.

[0058] The pull rod module 101 includes a first pull rod sleeve 102 movably inserted into the top of the housing 1, and a second pull rod sleeve 103 movably inserted into the first pull rod sleeve 102. The first pull rod sleeve 102 in the pull rod module 101 can slide and engage with the second pull rod sleeve 103 to achieve extension. The first pull rod sleeve 102 can retract into the housing 1 for storage and concealment. A limit cover 105 is provided at the top of the first pull rod sleeve 102, and a stop sleeve that engages with the limit cover 105 is installed on the second pull rod sleeve 103. When the first pull rod sleeve 102 and the second pull rod sleeve 103 are sliding and engaging, for example, when the second pull rod sleeve 103 is pulled out to its maximum stroke, the stop sleeve and the limit cover 105 prevent the second pull rod sleeve 103 from falling out of the first pull rod sleeve 102, thus maintaining the connection between the first pull rod sleeve 102 and the second pull rod sleeve 103.

[0059] The top of the second pull rod sleeve 103 is fitted with a top pull rod 104, and the top pull rod 104 has a top fitting hole formed in the middle for the second pull rod sleeve 103 to be inserted. The top pull rod 104 can be gripped by people. On the one hand, swinging the top pull rod 104 can drive the second pull rod sleeve 103 to rotate. On the other hand, when retracting, the top pull rod 104 will cooperate with the stop of the box body 1 for limiting the position. The top of the box body 1 is formed with a concave receiving groove 106, and an arc-shaped ring 107 is installed in the receiving groove to support the top pull rod 104. When the pull rod module 101 retracts, the top pull rod 104 retracts exactly into the concave receiving groove 106. The arc-shaped ring 107 supports the top pull rod 104, and there is a gap between the top pull rod 104 and the concave receiving groove 106, which makes it more convenient to pull out and use.

[0060] The bottom of the support base 10 is provided with a power wheel module 12, a steering wheel module and an auxiliary wheel module.

[0061] The support base 10 is equipped with a retractable foot pedal module 3.

[0062] The drive wheel module 12 includes a drive bracket and a drive wheel 14 mounted on the drive bracket. The drive bracket includes a drive shaft 13, and the drive wheel 14 can rotate around the drive shaft 13. The drive bracket has upright connecting seats 125 at both ends. The bottom of the support base 10 is formed with a connecting groove 114. The connecting seat 125 is formed with a connecting post 121 that can be inserted into the connecting groove 114. The connecting post 121 is formed with a bottom connecting hole 124. The top of the connecting groove 114 is formed with a connecting disc 118. The connecting disc 118 is formed with a top connecting hole 115 that is coaxially aligned with the bottom connecting hole 124.

[0063] During installation, the connecting seats 125 at both ends of the drive shaft 13 engage with the connecting grooves 114 of the support base 10 via connecting posts 121. The connecting posts 121 are inserted into the connecting grooves 114 at the bottom of the support base 10, ensuring that the top connecting hole 115 of the connecting disc 118 is coaxially aligned with the bottom connecting hole 124 of the connecting post 121. Screws are then inserted to achieve a locking connection. Since the connecting seats 125 are arranged vertically, they provide better support and better load-bearing capacity for the luggage compartment. This reduces the likelihood of the drive wheel module bending. In conjunction with the auxiliary wheel module 11, it further reduces the possibility of the drive wheel module bending and being damaged due to insufficient load-bearing capacity. The above solution facilitates the disassembly and replacement of the drive wheel module.

[0064] Furthermore, the auxiliary wheel module 11 includes a first auxiliary support wheel 112 and a second auxiliary support wheel 113. The first auxiliary support wheel 112 and the second auxiliary support wheel 113 are respectively installed on one side of the bottom of the support base 10. The steering wheel module is set on the other side of the bottom of the support base 10, and the power wheel module is set between the steering wheel modules. The first auxiliary support wheel 112 cooperates with the second auxiliary support wheel 113 to achieve multi-area support for the support base 10. The force distribution is relatively uniform, which can prevent the support base 10 from becoming uneven when moving and ensure the stability of the support.

[0065] Furthermore, the support base 10 is formed with a concave wheel mounting groove 111. The wheel mounting groove 111 cooperates with the drive wheel 14. After the drive wheel module is installed in place, under the action of the wheel mounting groove 111, a part of the drive wheel 14 will be located in the wheel mounting groove 111. That is, the gap between the support base 10 and the ground is reduced, the overall center of gravity is lowered, and the risk of the suitcase collapsing can be reduced when moving, further improving the stability of movement.

[0066] The connecting groove 114 includes a stepped first top hole 116 and a second top hole 117 formed at the bottom of the first top hole 116. The inner diameter of the second top hole 117 is larger than the inner diameter of the first top hole 116. The connecting post 121 includes a first mounting post 122 that mates with the first top hole 116 and a second mounting post 123 that mates with the second top hole 117. The outer diameter of the first mounting post 122 is adapted to the inner diameter of the first top hole 116. The outer diameter of the second mounting post 123 is adapted to the inner diameter of the second top hole 117. After the connecting post 121 of the power wheel module is inserted into the connecting groove 114, the first mounting post 122 mates with the first top hole 116, and the second mounting post 123 mates with the second top hole 117. At this time, the top end face of the second mounting post 123 will contact the end face at the connection between the first top hole 116 and the second top hole 117, further increasing the bearing area and effectively dispersing the gravity of the support base 10.

[0067] The bottom connecting hole 124 is connected to the first mounting post 122 and the second mounting post 123 respectively. After the connecting post 121 of the power wheel module is inserted into the connecting groove 114, the first mounting post 122 cooperates with the first top hole 116, and the second mounting post 123 cooperates with the second top hole 117. The screw is inserted between the top connecting hole 115 and the bottom connecting hole 124 to achieve a locking connection, prevent the power wheel module from falling out of the connecting groove 114, and ensure the stability of the connection.

[0068] Preferably, the cross-section of the connecting column 121 is circular, and the cross-section of the connecting seat 125 is square.

[0069] The inner wall of the connecting seat 125 is formed with a recessed fixing groove 126. The two ends of the drive shaft 13 are formed with fixing blocks 134 that connect with the fixing groove 126. The fixing blocks 134 are formed with a first transverse hole 135. The connecting seat 125 is formed with a second transverse hole 136 that is coaxially aligned with the first transverse hole 135. After the two ends of the drive shaft 13 are connected to the fixing groove 126 of the connecting seat 125 through the formed fixing blocks 134, the first transverse hole 135 of the fixing blocks 134 is coaxially aligned with the second transverse hole 136 of the connecting seat 125. Screws are inserted between the first transverse hole 135 and the second transverse hole 136 to achieve a fixed connection, effectively installing the drive shaft 13 and preventing the drive wheel 14 sleeved on the drive shaft 13 from falling off.

[0070] Furthermore, the drive wheel 14 is formed with a wheel hole 141 that rotates with the drive shaft 13, and a bearing seat 142 fitted onto the drive shaft 13 is installed in the wheel hole 141. Since the drive wheel 14 has a certain width, the part of the wheel hole 141 that contacts the drive shaft 13 contacts the drive shaft 13 through the bearing seat 142, thereby enabling the drive wheel 14 to rotate around the drive shaft 13 to drive the support base 10 to move.

[0071] Furthermore, the drive shaft 13 includes a first mounting cylinder 131 and a second mounting cylinder 132 arranged with a gap. The first mounting cylinder 131 and the second mounting cylinder 132 are respectively formed with hollow cavities 133. The first mounting cylinder 131 is equipped with a drive motor 144. The drive end of the drive motor 144 is equipped with a drive shaft 145. The outer end of the drive shaft 145 is equipped with a rolling bearing 146, which is installed in the second mounting cylinder 132. The drive motor 144 has wires leading out. The wires can be connected to the power supply module built into the support base 10 through a connector to supply power to the drive motor 144. When the drive motor 144 is working, the drive shaft 145 rotates. Since the outer end of the drive shaft 145 is connected to the second mounting cylinder 132 through the rolling bearing 146, neither the first mounting cylinder 131 nor the second mounting cylinder 132 will rotate.

[0072] A drive gear 147 is sleeved on the drive shaft 145. The drive gear 147 is located in the gap between the first mounting cylinder 131 and the second mounting cylinder 132. An internal gear 143 is fixedly installed inside the drive wheel 14. The internal gear 143 meshes with the drive gear 147 for transmission. When the drive shaft 145 rotates, the drive gear 147 sleeved on the drive shaft 145 will mesh with the internal gear 143 inside the drive wheel 14 for transmission. At the same time, the drive wheel 14 rotates synchronously to drive the drive wheel 14 to rotate around the drive shaft 13, thereby driving the support base 10 to move.

[0073] The steering wheel module includes a pair of steering support wheels 108, which are rotatably mounted on the bottom of the support base 10 through shaft holes. The power wheel module 12 is disposed between the two steering support wheels 108. A steering mechanism is provided inside the support base 10. The steering mechanism typically includes a steering arm and a steering coupling sleeve. The steering coupling sleeve is rotatably connected to the middle end of the steering arm. The steering arm is similar to a parallelogram structure. When the steering coupling sleeve rotates, the steering arm will shift left and right as a whole. The steering arm can drive the two steering support wheels 108 rotatably mounted on the support base 10 to rotate horizontally, thereby achieving steering. The above-mentioned steering mechanism is widely used in luggage and bags and is a common existing technology. Those skilled in the art can directly derive it from the existing technology without any creative effort. Therefore, the specific structure will not be described in detail here.

[0074] The steering coupling sleeve inside the support base 10 is connected to the first pull rod sleeve 102 through a telescopic rod structure. When the first pull rod sleeve 102 moves up and down, it can always be connected to the steering coupling sleeve through the telescopic rod structure. When the first pull rod sleeve 102 rotates, it can drive the steering coupling sleeve to rotate through the telescopic rod structure. The steering mechanism controls the steering support wheel 108 to rotate horizontally at the bottom of the support base 10, thereby controlling the steering.

[0075] The power module 2 includes a battery bracket 21 detachably mounted on the support base 10. The support base 10 has a bracket mounting groove 217. The battery bracket 21 is detachably inserted into the bracket mounting groove 217. The battery bracket 21 has a power cavity 210, and a power battery 211 is detachably mounted in the power cavity 210. The power battery 211 is fitted with a battery casing 212. An internal compression spring 213 is provided inside the power cavity 210. The internal compression spring 213 can cause the battery casing 212, on which the power battery 211 is mounted, to elastically pop outward. The battery casing 212 has a battery locking groove 227. The battery bracket 21 has an elastic locking structure 22 that engages with the battery locking groove 227. The elastic locking structure 22 includes a battery locking block 222 that can be elastically inserted into the power cavity 210 and an unlocking block 23 that can move the battery locking block 222 away from the power cavity 210.

[0076] The battery casing 212, housing the power battery 211, is inserted into the power cavity 210 of the battery bracket 21. During installation, the battery locking block 222 of the elastic locking structure 22 slides and engages with the battery casing 212 until the battery locking block 222 is laterally aligned with the battery locking groove 227 of the battery casing 212. At this point, the battery locking block 222 is embedded into the battery locking groove 227, thus locking the battery casing 212. The battery casing 212 is then locked within the power cavity 210, ensuring stable power supply and conductivity. To unlock, the unlocking block is moved. 23. Unlocking block 23 will move battery locking block 222 away from the power cavity 210, that is, battery locking block 222 will disengage from the battery locking groove 227 of battery casing 212; under the elastic drive of the internal compression spring 213 of power cavity 210, battery casing 212 will pop out of power cavity 210, thereby realizing battery disassembly; without the use of tools and without the need for screw connection, the installation and disassembly of power battery 211 can be realized. The whole process of disassembly and assembly is very convenient. When the power battery 211 is low in power, it can be removed for charging, which enhances its practicality.

[0077] In one embodiment, the battery module formed by the battery casing 212 and the power battery 211 is a power bank, and the rated energy value of the lithium-ion battery of the power bank does not exceed 100Wh; the power module 2 of this application can be used in a 20-inch suitcase, which is carry-on luggage, and the power bank complies with civil aviation regulations and can be carried on board, thereby ensuring a stable power supply to the suitcase.

[0078] Specifically, the outer end of the battery locking block 222 is formed with a stop surface 223 that cooperates with the stop of the battery locking groove 227 and a guide slope 224 that slides with the battery casing 212. The stop surface 223 is formed on the inner side wall of the outer end of the battery locking block 222, and the guide slope 224 is formed on the outer side wall of the outer end of the battery locking block 222. Under the elastic action, a portion of the battery locking block 222 extends into the power cavity 210. When the power battery 211 is installed, the battery casing 212 abuts against the battery locking block 222. Under the action of the guide slope 224, the battery locking block 222 will retract a portion. The battery locking block 222 and the battery casing 212 slide into each other until the battery locking block 222 is laterally aligned with the battery locking groove 227 of the battery casing 212. At this time, the battery locking block 222 is embedded in the battery locking groove 227, and the stop surface 223 of the battery locking block 222 will stop and cooperate with the battery locking groove 227. At this time, the battery locking block 222 cannot retract from the battery locking groove 227, thereby locking the battery casing 212.

[0079] Furthermore, the elastic locking structure 22 also includes an unlocking seat 221 disposed on the battery bracket 21. The side wall of the unlocking seat 221 is formed with an outer sliding groove 225 for the battery locking block 222 to slide. The battery bracket 21 is formed with an inner sliding groove 226 that is laterally aligned with the outer sliding groove 225 and allows the battery locking block 222 to pass through. The outer sliding groove 225 and the inner sliding groove 226 cooperate to form a continuous track for the battery locking block 222 to slide. This ensures that when the battery locking groove 227 of the battery casing 212 moves to be laterally aligned with the outer sliding groove 225 and the inner sliding groove 226, the battery locking groove 227 can be accurately inserted into the battery locking groove 227 of the battery casing 212, thereby locking the power battery 211.

[0080] Furthermore, the unlocking seat 221 is also equipped with a locking spring 228 that drives the battery locking block 222 to be elastically inserted into the power chamber 210. The locking spring 228 is a compression spring, and the elastic force of the locking spring 228 can drive the outer end of the battery locking block 222 to extend into the power chamber 210 when there is no other external force.

[0081] Furthermore, the battery locking block 222 has an unlocking groove 229 through which the unlocking block 23 slides; when the battery locking block 222 slides, it will slide and cooperate with the unlocking groove 229 to drive the battery locking block 222 away from the power cavity 210 to unlock, and the unlocking groove 229 can maintain the connection between the unlocking block 23 and the battery locking block 222.

[0082] Preferably, the moving direction of the battery locking block 222 is perpendicular to the moving direction of the unlocking block 23.

[0083] Furthermore, the unlocking block 23 includes a first sliding bar 231 with a first width and a second sliding bar 232 with a second width. The second sliding bar 232 is integrally formed on the outer end of the second sliding bar 232, and the transition area between the first sliding bar 231 and the second sliding bar 232 is formed with an unlocking slope 233. In the locked state, the unlocking block 23 retracts partially, and the second sliding bar 232 contacts the unlocking groove 229 of the battery locking block 222. When unlocking is required, the unlocking block 23 moves towards the inner end of the unlocking seat 221. At this time, the unlocking inclined surface 233 between the first sliding bar 231 and the second sliding bar 232 will slide and engage with the unlocking groove 229 of the battery locking block 222, which will cause the battery locking block 222 to move away from the power cavity 210. That is, the battery locking block 222 will disengage from the battery locking groove 227 of the battery casing 212. Under the elastic drive of the internal compression spring 213 of the power cavity 210, the battery casing 212 will pop out of the power cavity 210, thereby realizing the removal of the battery.

[0084] Furthermore, the first width is greater than the second width, and the size of the first width does not exceed the width of the unlocking slot 229; this prevents the unlocking block 23 from being unable to pass through the unlocking slot 229, ensuring that the unlocking block 23 can always slide and cooperate with the unlocking slot 229, thus ensuring the stability of unlocking.

[0085] Furthermore, the unlocking base 221 is provided with a first sliding guide rail 234 for guiding the first sliding bar 231 to slide and a second sliding guide rail 235 for guiding the second sliding bar 232 to slide. The first sliding bar 231 and the second sliding bar 232 move on the corresponding first sliding guide rail 234 and second sliding guide rail 235, and their movement path remains fixed. When the unlocking block 23 moves, the distance that drives the battery locking block 222 to move can also remain consistent. When unlocking, there will be no large error.

[0086] Furthermore, the outer end of the unlocking seat 221 is formed with an unlocking drive groove 236, and an unlocking press block 237 is installed in the unlocking drive groove 236. The unlocking press block 237 is connected to the first sliding bar 231. An unlocking compression spring 239 is provided inside the unlocking seat 221 to drive the unlocking seat 221 to elastically approach the unlocking drive groove 236. When the battery is installed, the elastic force of the unlocking compression spring 239 drives the unlocking press block 237 to move toward the unlocking drive groove 236. That is, the first sliding bar 231 of the unlocking block 23 cooperates with the battery locking groove 227 of the battery locking block 222. At this time, the elastic force of the locking spring 228 can drive the outer end of the battery locking block 222 to extend into the power cavity 210 when there is no other external force.

[0087] Preferably, the inner end of the unlocking press block 237 is formed with a limiting block 238 that cooperates with the stop of the unlocking drive groove 236; the limiting block 238 can prevent the unlocking press block 237 from popping out of the unlocking drive groove 236, and can ensure that the unlocking block 23 is always in cooperation with the unlocking groove 229 of the battery locking block 222.

[0088] Furthermore, an inner conductive block 214 is installed on the inner end wall of the power cavity 210, and multiple conductive contacts 215 are formed on the outer end of the inner conductive block 214. The battery casing 212 is equipped with battery metal contacts 216 that are laterally aligned with the conductive contacts 215. The battery metal contacts 216 are connected to the power supply battery. After the battery casing 212 is installed into the power cavity 210, the inner conductive block 214 of the power cavity 210 contacts the battery metal contacts 216 of the battery casing 212, thereby realizing the power supply connection and enabling power supply to the entire power module 2.

[0089] The inner conductive block 214 is connected to a control board, and the control board leads out wires that can be connected to the drive motor signal of the power wheel module 12 to provide power to the drive motor and ensure the rotation support of the power wheel module 12.

[0090] The foot pedal module 3 includes a foot pedal bracket 31 mounted on a support base 10. The support base 10 has a foot pedal mounting groove 317 for mounting the foot pedal bracket 31. The foot pedal bracket 31 has a sliding cavity 311 along its length. A support body 312 is slidably mounted in the sliding cavity 311. A press-type elastic self-locking mechanism 32 and a sliding guide structure 313 are provided between the sliding cavity 311 and the support body 312. The press-type elastic self-locking mechanism 32 includes a guide rail 321 arranged along the length of the support body 312. A locking structure is installed at the outer end of the guide rail 321. The locking structure includes a foot pedal locking block 324 to prevent the guide post 331 from retracting and a guide block 326 to guide the guide post 331 from the foot pedal locking block 324 to the guide rail 321. The sliding cavity 311 is provided with a guide post 331 that slides with the guide rail 321 and a movable support member 33 for the guide post 331 to swing laterally.

[0091] When a portion of the support body 312 extends outward from the sliding cavity 311, it functions as a foot pedal support; conversely, the support body 312 can also retract into the sliding cavity 311 for concealment and storage. When the support body 312 needs to be concealed and stored in the sliding cavity 311, pushing the support body 312 causes the guide post 331 within the sliding cavity 311 to move from the guide rail 321 to the foot pedal locking block 324 of the locking structure. The foot pedal locking block 324 prevents the guide post 331 from retracting, and the support body 312 then... The foot pedal is locked within the sliding cavity 311. When pressed to hide, it can be done by pressing with the foot without bending over or using the hands. When the foot pedal is needed, the support body 312 is pressed again. At this time, the guide block 326 of the locking structure can move the guide post 331 from the foot pedal locking block 324 to the guide rail 321. The support post will then pop out elastically for foot pedal support. This achieves the hiding and extending of the foot pedal. The hiding and extending efficiency is extremely fast, and it takes up little space in the suitcase, making it convenient for most people to use.

[0092] Specifically, the sliding guide structure 313 includes a guide rod 314 arranged along the length of the sliding cavity 311, and a support body 312 formed with a guide hole 315 that slides with the guide rod 314. The guide rod 314 is fitted with a compression spring 316 that ejects the support body 312 outward. When the guide post 331 disengages from the locking structure, that is, when the support body 312 is needed for foot support, the elastic force of the compression spring 316 will drive the support body 312 to eject outward along the sliding cavity 311. When ejected, the guide rod 314 slides with the guide hole 315 to ensure the stability of the movement of the support body 312.

[0093] Furthermore, the length of the guide rail 321 is limited. When the guide post 331 slides into the guide rail 321 at the end, the support body 312 cannot continue to pop out, preventing the entire support body 312 from sliding out of the power cavity. Also, a part of the support body 312 is located in the sliding cavity 311, which can have a certain force-bearing space to prevent the support body 312 from bending and being damaged.

[0094] Furthermore, one end of the guide rod 314 is fixedly installed on the inner end wall of the sliding cavity 311, and one end of the compression spring 316 is fixedly installed on the inner end wall of the sliding cavity 311. When the support body 312 is hidden and stored, the compression spring 316 will be compressed. Since the outer diameter of the compression spring 316 is smaller than the inner diameter of the guide hole 315, the compression spring 316 can be compressed in the guide hole 315, ensuring that the support body 312 can be completely hidden in the sliding cavity 311.

[0095] The locking structure includes a first extension track 322 and a second extension track 323 connected to the guide track 321. The first extension track 322 and the second extension track 323 cooperate with the guide track 321 to form a track similar to a "Y". In order to ensure better connectivity between the first extension track 322 and the guide track 321, a guide surface is provided between the guide track 321 and the first extension track 322. This guide surface can increase the connectivity and smoothness between the first extension track 322 and the guide track 321. Therefore, when locking the support 312, after the guide post 331 moves to the end of the guide track 321, it will enter the first extension track 322.

[0096] Subsequently, the foot pedal locking block 324 and the guide block 326 are formed between the first extension track 322 and the second extension track 323. The guide post 331 moves sequentially along the guide track 321, the first extension track 322, the foot pedal locking block 324, the second extension track 323, and the guide track 321. After the guide post 331 moves from the first extension track 322 to the foot pedal locking block 324, the support body 312 moves inward a part and then cooperates with the foot pedal locking block 324. At this time, the foot pedal locking block 324 will lock the guide post 331 to prevent the support body 312 from popping outward.

[0097] When the support body 312 needs to be unlocked and ejected, press the support body 312. The guide block 326 of the support body 312 will cooperate with the guide post 331. The structure of the guide block 326 will guide the guide post 331 from the foot lock block 324 to the second extension track 323. Since the second extension track 323 is connected to the guide track 321, the guide post 331 continues to move along the guide track 321, so the support body 312 can continue to eject outward.

[0098] Specifically, the foot lock block 324 has a recessed foot lock groove 325, and the guide block 326 has a guide post 331 that moves from the first extension track 322 to the first inclined surface 327 of the foot lock groove 325. When the support body 312 is pressed, after the support body 312 is pressed to the end of the sliding cavity 311, the guide post 331 is located at the end of the first extension track 322 and will cooperate with the first inclined surface 327 of the guide block 326. Then, when the support body 312 is released, the support body 312 will move outward a part. At this time, the guide post 331 will move to the foot lock groove 325 of the foot lock block 324 under the guidance of the first inclined surface 327. At this time, the support body 312 cannot continue to pop out, so as to lock the guide post 331.

[0099] Specifically, the guide block 326 is also formed with a guide post 331 moving from the foot pedal locking groove 325 to the second extension track 323 on a second inclined surface 328. When the support body 312 needs to be unlocked, the support body 312 is pressed again. At this time, the support body 312 will move a part into the sliding cavity 311. At the same time, the guide post 331, guided by the second inclined surface 328, moves from the foot pedal locking groove 325 to the second extension track 323. At this time, the support body 312 is unlocked and can be popped outward. At the same time, the guide post 331 moves from the second extension track 323 to the track.

[0100] Furthermore, the first inclined surface 327 and the second inclined surface 328 form a triangular block, with the tip of the triangular block tilted towards the first extended track 322; the foot pedal locking groove 325 is a triangular groove with a triangular cross-section. Therefore, during unlocking, the triangular block has a limiting function, and the guide post 331 is guided to the second extended track 323 for easy unlocking.

[0101] The guide post 331 is longitudinally installed in the sliding cavity 311. The movable support 33 includes a lateral swing rod 332 that is laterally swayed and installed on the foot pedal bracket 31. The guide post 331 is formed on the top of the lateral swing rod 332. Since the first extension rail 322 and the second extension rail 323 cooperate with the guide rail 321 to form a track similar to a "Y", the lateral position of the guide post 331 will change. With the movement of the lateral swing rod 332, the guide post 331 can adapt to the position accordingly, which is convenient for cooperation with the locking structure.

[0102] Furthermore, the other end of the lateral swing rod 332 is formed with a movable connecting hole 333, and the foot pedal bracket 31 is provided with a fixed post 334 that is rotatably connected to the movable connecting hole 333. The lateral swing rod 332 is rotatably engaged with the fixed post 334 through the movable connecting hole 333. When the guide post 331 formed on the top of the lateral swing rod 332 moves from the guide rail 321 to the first extension rail 322, the lateral swing rod 332 will swing adaptively so that the guide post 331 can enter the first extension rail 322 and then pass through the foot pedal locking groove 325 in sequence to achieve locking. When unlocking, the guide post 331 moves along the foot pedal locking groove 325, the second extension rail 323, and the guide rail 321 to achieve unlocking.

[0103] The sliding cavity 311 is formed with a movable groove 335 for the guide post 31 to swing laterally. When the guide post 31 passes through the locking structure, the lateral swing rod 332 will swing horizontally. The movable groove 335 can reserve corresponding space for the lateral swing rod 332 to swing horizontally.

[0104] Furthermore, the top of the housing 1 is also equipped with a charging port for discharging. The charging port is connected to the power battery of the power module 2. The internal conductive block 214 leads out a wire, which is connected to the charging port, so that it can discharge to the outside and charge electronic devices such as mobile phones.

[0105] It should be noted that, in one embodiment, the top pull rod 104 houses a controller and a top battery that powers the controller. The controller is a top circuit board, and the power supply module and the drive wheel module 12 are electrically connected to the control board. The top circuit board and the bottom circuit board are connected via a wireless communication module to achieve wireless control. The top pull rod 104 is equipped with a start button and a toggle button connected to the top circuit board. Pressing the start button controls the start of the drive wheel module, pushing the toggle button forward controls the drive wheel module 12 to move forward, and pushing the toggle button backward controls the drive wheel module 12 to move backward, thereby controlling the forward and backward movement of the suitcase.

[0106] In summary, this utility model possesses the excellent characteristics described above, enabling it to achieve unprecedented efficiency in use and thus becoming a highly practical product. The above description is merely a preferred embodiment of this utility model. For those skilled in the art, based on the concept of this utility model, 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 this utility model.
