A rack passing through the lifting plate and multiple circumferentially distributed guide rods are fixed between the platform and the base plate. Linear bearings that engage with each of the guide rods are mounted on the lifting plate. Springs are sleeved on the guide rods between the lifting plate and the base plate. A motor is fixed to the lower side of the lifting plate, and the motor's output shaft passes through the lifting plate and is fitted with a drive bevel gear. An impact frame passing through the platform and engaging with the impact plate is fixed to the upper side of the lifting plate. A transmission shaft is mounted on the impact frame, and a transmission bevel gear meshing with the drive bevel gear and an incomplete gear engaging with the rack are mounted on the transmission shaft.

[0005] Furthermore, the present invention provides a continuously jumping mobile platform, wherein the rack and the incomplete gear are provided in two corresponding positions, and the two racks are symmetrically distributed.

[0006] Furthermore, the present invention provides a continuously jumping mobile platform, wherein the impact platform includes a U-shaped support and an inverted U-shaped impact member fixedly connected by screws. The U-shaped support is fixed to the lifting plate by screws, and the impact member is provided with a contact ring for impacting the impact plate.

[0007] Furthermore, the present invention provides a continuously jumping mobile platform, wherein the two ends of the drive shaft are respectively mounted between the impact member and the U-shaped support via ball bearings, and the drive bevel gear and two incomplete gears are respectively mounted on the drive shaft via flat keys and retaining rings.

[0008] Furthermore, the present invention provides a continuously jumping maneuvering platform, wherein the lower side of the platform is provided with an upper sleeve corresponding to each guide rod, the upper end of the guide rod is inserted into the corresponding upper sleeve and fixed to the platform with screws, and the upper side of the base plate is provided with a lower sleeve corresponding to each guide rod, the lower end of the guide rod is inserted into the corresponding lower sleeve and fixed to the base plate with screws.

[0009] Furthermore, the present invention provides a continuously jumping mobile platform, wherein the base plate is provided with a spring seat around the lower sleeve, the bottom of the lifting plate is provided with an annular groove around the guide rod, the lower end of the spring is located in the spring seat, and the upper end of the spring is located in the annular groove.

[0010] Furthermore, the present invention provides a continuously jumping maneuvering platform, wherein the lifting plate is provided with a bracket corresponding to a linear bearing, the linear bearing passes through the bracket and the lifting plate from top to bottom and is fixed by screws, and the guide rod passes through the corresponding linear bearing.

[0011] Furthermore, the present invention provides a continuously jumping mobile platform, wherein the base plate is provided with grooves corresponding to the legs and the rack, the upper end of the legs is engaged in the corresponding grooves and fixed by screws, and the lower end of the rack is engaged in the corresponding grooves and fixed by screws.

[0012] Furthermore, the present invention provides a continuously jumping maneuvering platform, wherein the impact plate is provided with multiple support columns, the lower ends of which are fixed to the platform by screws.

[0013] Furthermore, the present invention provides a continuously jumping maneuvering platform, wherein the support legs are provided in four and are evenly distributed circumferentially, and the guide rods are provided in four and are evenly distributed circumferentially.

[0014] Compared with existing technologies, the continuous jumping maneuvering platform of this invention has the following advantages: This invention uses a base plate and a platform spaced vertically apart, and a lifting plate located between the base plate and the platform. Multiple circumferentially distributed support legs are fixed to the lower side of the base plate, and an impact plate is fixed to the upper side of the platform. A rack passing through the lifting plate and multiple circumferentially distributed guide rods are fixed between the platform and the base plate. Linear bearings that mate with each guide rod are installed on the lifting plate. Springs are fitted onto the guide rods between the lifting plate and the base plate. A motor is fixed to the lower side of the lifting plate, with its output shaft passing through the lifting plate and mounting a drive bevel gear. An impact frame passing through the platform and mates with the impact plate is fixed to the upper side of the lifting plate.

This constitutes a compact, easy-to-operate, highly adaptable, easily passable, and highly reliable continuous jumping maneuvering platform. In practical applications, after the motor is started, the rotation of the motor's output shaft drives the incomplete gear to rotate sequentially through the drive bevel gear, transmission bevel gear, and transmission shaft. The rotation of the incomplete gear, through its meshing with the rack, moves the impact platform and lifting plate downwards and compresses the spring. When the incomplete gear rotates to the point where its empty tooth part is on one side of the rack, the incomplete gear disengages from the rack, the spring is released, and it pushes the lifting plate and impact platform upwards rapidly until the top of the impact platform collides with the impact plate. The impact of the impact platform against the impact plate causes the entire motorized platform to jump. The continuous rotation of the motor causes the impact platform to repeatedly impact the impact plate, thereby achieving continuous jumping of the motorized platform. Furthermore, the jumping frequency of the motorized platform can be easily and quickly adjusted by controlling the motor speed. Compared with existing technologies, 1. This invention uses bevel gear transmission, which changes the direction of force transmission, reduces the transmission size of the transmission mechanism, and improves structural compactness and space utilization; 2. Traditional mobile platforms can often only achieve single jumps or low-frequency jumps in jumping motion, which is difficult to meet the continuous jumping requirements in complex scenarios. This invention, through innovative structural design, can achieve continuous jumps, improving the flexibility and adaptability of the mobile platform, and is suitable for more complex terrains and diverse application scenarios; 3. The mobile platform provided by this invention has a core motion mechanism mainly based on mechanical structure, which is not only simple in structure, easy to control, safe and reliable, but also enables the mobile platform to achieve efficient energy storage and rapid release in a limited space through the use of ingenious mechanical transmission methods.

[0024] First, it should be noted that the directional terms such as up, down, left, right, front, and back used in this invention are merely descriptions based on the accompanying drawings for ease of understanding, and are not intended to limit the technical solution or the scope of protection claimed in this invention.

[0025] like Figures 1 to 8 The embodiment of the continuously jumping maneuvering platform of the present invention shown includes a base plate 1 and a platform 2 spaced apart vertically, and a lifting plate 3 located between the base plate 1 and the platform 2. The base plate 1 has multiple circumferentially distributed support legs 11 fixed to its lower side. The platform 2 has an impact plate 21 fixed to its upper side. A rack 4 passing through the lifting plate 3 and multiple circumferentially distributed guide rods 5 are fixed between the platform 2 and the base plate 1. Linear bearings 31, each engaging with one of the guide rods 5, are mounted on the lifting plate 3. Springs 6 are sleeved on the guide rods 5 between the lifting plate 3 and the base plate 1. A motor 7 is fixed to the lower side of the lifting plate 3, with its output shaft passing through the lifting plate 3 and a drive bevel gear 71 mounted thereon. An impact frame 8, passing through the platform 2 and engaging with the impact plate 21, is fixed to the upper side of the lifting plate 3. A transmission shaft 9 is mounted on the impact frame 8, and a transmission bevel gear 91 meshing with the drive bevel gear 71 and an incomplete gear 92 engaging with the rack 4 are mounted on the transmission shaft 9.

[0026] The above configuration constitutes a compact, easy-to-operate, highly adaptable, well-passable, and highly reliable continuous jumping motorized platform. In practical applications, after starting the motor 7, the output shaft of the motor 7 rotates, which sequentially drives the incomplete gear 92 to rotate via the drive bevel gear 71, transmission bevel gear 91, and transmission shaft 9. The rotation of the incomplete gear 92, through its meshing with the rack 4, causes the impact platform 8 and the lifting plate 3 to move downwards and compress the spring 6. When the incomplete gear 92 rotates to the point where its empty tooth part is on one side of the rack 4, the incomplete gear 92 disengages from the rack 4, the spring 6 is released, and pushes the lifting plate 3 and the impact platform 8 upwards rapidly until the top of the impact platform 8 collides with the impact plate 21. The impact of the impact platform 8 against the impact plate 21 enables the entire motorized platform to jump. The continuous rotation of the motor 7 causes the impact platform 8 to repeatedly impact the impact plate 21, thereby achieving continuous jumping of the motorized platform. Furthermore, the jumping frequency of the motorized platform can be easily and quickly adjusted by controlling the speed of the motor 7. Compared with existing technologies, 1. This invention uses bevel gear transmission, which changes the direction of force transmission, reduces the transmission size of the transmission mechanism, and improves structural compactness and space utilization; 2. Traditional mobile platforms often only achieve single jumps or low-frequency jumps in jumping motions, making it difficult to meet the continuous jumping requirements in complex scenarios. This invention, through innovative structural design, can achieve continuous jumps, improving the flexibility and adaptability of the mobile platform, and making it suitable for more complex terrains and diverse application scenarios; 3. The mobile platform provided by this invention has a core motion mechanism mainly based on mechanical structures, which is not only simple in structure, easy to control, and safe and reliable, but also enables the mobile platform to achieve efficient energy storage and rapid release in a limited space through the use of ingenious mechanical transmission methods. It should be noted that, in order to improve the stability of the structure and movement, this invention typically sets two racks 4 and two incomplete gears 92 in a one-to-one correspondence, and the two racks 4 are symmetrically distributed; similarly, this invention sets four legs 11 and four guide rods 5, and the four legs 11 and four guide rods 5 are evenly distributed circumferentially. However, it should be noted that the support legs 11 and guide rods 5 are not limited to four; three or more can also be provided, which can achieve the technical purpose of the present invention in the same way.

[0027] In a specific embodiment, the impact platform 8 adopts a split design for modular assembly and disassembly, facilitating easy assembly and disassembly. Specifically, it includes a U-shaped support 81 and an inverted U-shaped impact member 82, which are fixedly connected by screws. The U-shaped support 81 is fixed to the lifting plate 3 by screws, and the impact member 82 is provided with a contact ring 821 that impacts the impact plate 21. This structural arrangement utilizes the contact ring 821 to impact the impact plate 21, reducing the contact area between the two and concentrating the collision in the middle, thus improving the impact force effect and the stability and reliability of the jump. Correspondingly, in this specific embodiment, both ends of the transmission shaft 9 are respectively installed between the impact member 82 and the U-shaped support 81 via ball bearings 93, and the transmission bevel gear 91 and two incomplete gears 92 are respectively installed on the transmission shaft 9 via flat keys and retaining rings. This arrangement features a simple structure, convenient assembly and disassembly, and smooth operation. However, it should be noted that how to install the transmission shaft via bearings and how to install the gears via flat keys and retaining rings are well known to those skilled in the art and will not be described in detail here.

[0028] In a specific embodiment, the present invention provides an upper sleeve 22 corresponding to each guide rod 5 on the lower side of the platform 2, allowing the upper end of the guide rod 5 to be inserted into the corresponding upper sleeve 22 and fixed to the platform 2 with screws; and a lower sleeve (located inside the spring seat, not shown in the figure) corresponding to each guide rod 5 is provided on the upper side of the base plate 1, allowing the lower end of the guide rod 5 to be inserted into the corresponding lower sleeve and fixed to the base plate 1 with screws. This structure, by providing the upper sleeve 22 and the lower sleeve, improves the convenience of installing the guide rod 5 on the one hand, and improves the structural strength and connection stability on the other hand. To ensure the stability of the spring seat 12, this specific embodiment provides a spring seat 12 around the lower sleeve on the base plate 1, and an annular groove 32 around the guide rod 5 is provided at the bottom of the lifting plate 3, with the lower and upper ends of the spring 6 placed in the spring seat 12 and the annular groove 32 respectively, so as to prevent the spring from being biased to one side during compression, thus affecting the release force effect. To facilitate the positioning and installation of the linear bearing 31, this specific embodiment provides a bracket 33 on the lifting plate 3 that corresponds one-to-one with the linear bearing 31, allowing the linear bearing 31 to pass through the bracket 33 and the lifting plate 3 from top to bottom and be fixed with screws. The guide rod 5 passes through the corresponding linear bearing 31.

[0029] In practical applications, the present invention also provides grooves on the base plate 1 corresponding to the support legs 11 and the rack 4, allowing the upper ends of the support legs 11 to be fitted into the corresponding grooves and fixed with screws, and the lower ends of the rack 4 to be fitted into the corresponding grooves and fixed with screws, thereby improving the ease of assembly and disassembly. Furthermore, the impact plate 21 is provided with four support pillars 211, the lower ends of which are fixed to the platform 2 with screws, facilitating structural arrangement and providing movement space for the impact platform 8. However, it should be noted that the impact plate 21 may have three or more support pillars 211, not just four.

[0030] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications made by those skilled in the art based on the technical solutions of the present invention without departing from the design concept of the present invention should fall within the scope of protection defined by the claims of the present invention.
