[0016] II. Multi-dimensional structural reinforcement to ensure performance stability Addressing the weakness of simple support components in terms of stability, this support frame enhances stability through a three-dimensional structural design: Reinforced connection structure: The mounting frame and the connecting rod are connected by locking bolts with washers. The locking rod on the surface of the washer is embedded in the locking hole of the mounting frame, forming a double fixation of bolt locking and rod hole limiting, which prevents the mounting frame from loosening and shifting during performance; Optimized support structure: The support base and the adjusting rod are height-fixed through multi-position adjustment holes and adjusting bolts. Combined with the hinged linkage structure of the positioning seat and the deformation seat, the support components form a stable triangular mechanical support, which can withstand greater weight and is not easy to shake. Upgraded keyboard locking: The airbag-type limiting component inside the base is inflated through the air tube and can form a flexible wrap around and fix the keyboard from the bottom and sides. Combined with the mechanical locking of the locking tongue and the locking seat, it provides double protection to prevent the keyboard from sliding or tipping over during playing, completely eliminating the risk of shaking and tipping over with traditional support devices.

[0017] III. Improved ease of use and lowered barrier to entry This support frame features a simple assembly-free design, and is compatible with the 180° quick-release feature of electronic keyboards. One-click unfolding and storage: simply rotate the support components to unfold or store the frame, and the deformable locking strip of the locking seat enables quick fixing and releasing of the support base without the need for additional tools; Intuitive height adjustment: The evenly distributed adjustment holes on the adjustment rod, together with the adjustment bolt, can quickly achieve multi-level height adjustment to suit the sitting and standing performance needs of users of different heights; Intelligent locking mechanism: The air bladder can be inflated and deflated via the air valve, and the air pressure gauge monitors the air pressure value in real time. This ensures that the air bladder is effectively fixed to the instrument body and avoids over-inflation that could damage the equipment. The operation process is simple and easy to understand, reducing the learning curve for novice users. Attached Figure Description

[0026] The following is combined Figures 1-9 The present invention describes a foldable electronic keyboard support frame.

[0027] In one embodiment, a foldable electronic keyboard support frame includes: a placement mechanism 100, which includes two placement frames 110, two connecting rods 120, and two support assemblies 140. The outer wall of the placement frame 110 is fixedly connected with a threaded sleeve 111. The middle of the connecting rod 120 is hollowed out to form a movable cavity. A locking bolt 130 is provided at the movable cavity of the connecting rod 120. The end of the locking bolt 130 passes through the movable cavity and is threadedly connected to the threaded sleeve 111. The support assembly 140 includes a support base 141 and an adjusting bolt 144. An adjusting rod 142 is inserted into the top of the support base 141. An evenly distributed adjusting hole 143 is opened on one side of the adjusting rod 142. The end of the adjusting bolt 144 passes through the support base 141 and extends into the adjusting hole 143. The adjusting rod 142 is rotatably connected to the bottom of the placement frame 110. A connecting member is provided between the placement frame 110 and the adjusting rod 142. The locking mechanism 200 includes two placement seats 210 disposed at the top of the placement rack 110, a limiting component 220, and a locking component 230; The limiting component 220 includes a connecting pipe 223. Two telescopic sleeves 221 are provided on opposite sides of the two placement seats 210. An airbag 222 is provided inside the telescopic sleeve 221. The two airbags 222 are connected to each other in the horizontal direction. The two airbags 222 are connected to each other in the vertical direction through the connecting pipe 223. An air injection pipe 224 is provided on the surface of one of the airbags 222. The end of the air injection pipe 224 away from the airbag 222 passes through the placement seat 210 and is provided with an air nozzle 225. The locking mechanism 200 also includes a bolt 240 and a lock seat 241, which are respectively disposed on the corresponding placement seats 210.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the connecting components include a positioning seat 145 fixedly connected to the bottom of the placement frame 110 and a deformation seat 146 fixedly connected to the adjusting rod 142. The deformation seat 146 is hinged to the positioning seat 145. A sliding groove 147 is provided on the positioning seat 145, and a connecting rod 148 is provided on the deformation seat 146. The end of the connecting rod 148 away from the deformation seat 146 slides in the sliding groove 147. When storing, the support assembly 140 needs to be rotated 90 degrees. During the rotation, the deformation seat 146 will rotate synchronously with the support assembly 140, pushing the connecting rod 148. One end of the connecting rod 148 is hinged, and the other end slides in the sliding groove 147 to achieve deformation adaptation.

[0029] Two locking seats 150 are fixedly connected to the bottom of the placement rack 110, and two locking strips 151 are provided on the inner wall of the locking seats 150. When stored for portability, the locking seats 150 can store the support base 141. The deformable locking strips 151 can deform freely during storage, and can also be more easily released when the locking state is released.

[0030] Both ends of the connecting rod 120 are equipped with protective corners 121, which are made of rubber. The rubber protective corners 121 can effectively protect against excessive impacts.

[0031] A washer 131 is provided on the surface of the locking bolt 130, and the washer 131 is located between the locking bolt 130 and the connecting rod 120. The washer 131 can increase the locking effect between the locking bolt 130 and the connecting rod 120, thereby increasing the stability of the connection between the two placement brackets 110.

[0032] Two locking rods 132 are fixedly connected to the surface of the gasket 131, and the surface of the placement rack 110 is provided with locking holes 112 that cooperate with the locking rods 132. During the locking process of the placement rack 110, the locking rods 132 will automatically enter the locking holes 112, and at the same time, the side of the locking rods 132 will limit the side of the connecting rod 120, further increasing the stability of the connection between the two placement racks 110.

[0033] like Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, the locking assembly 230 includes a locking frame 231 disposed at the top of the placement seat 210. A spring 232 is fixedly connected to the inner top wall of the locking frame 231. A piston plate 233 is fixedly connected to the top of the spring 232. The top of the piston plate 233 passes through the locking frame 231 and is fixedly connected to a locking plate 234. The bottom end of the locking frame 231 is connected to a second connecting pipe 235. The end of the second connecting pipe 235 away from the locking frame 231 passes through the placement seat 210 and is provided with a second connector 236. A first connecting pipe 226 is provided on the surface of the air injection pipe 224. A first connector 227 matching the second connector 236 is provided at the end of the first connecting pipe 226 away from the air injection pipe 224.

[0034] A pressure gauge 228 is embedded in the surface of the placement base 210, and the pressure gauge 228 is connected to the airbag 222. The pressure gauge 228 can monitor the air pressure inside the airbag 222 to avoid over-inflation and under-inflation.

[0035] The top of the placement seat 210 is provided with a contact pad 211, and the top of the contact pad 211 has evenly distributed grooves. The contact pad 211 can better connect two corresponding placement seats 210 together and avoid damage to the surface of the placement seat 210 when locking.

[0036] A limiting frame 237 is fixedly connected to the inner wall of the locking frame 231. The limiting frame 237 has a strip-shaped cutout in the middle, and a sealing ring is provided on the surface of the piston plate 233. The limiting frame 237 can restrict the position of the piston plate 233, while the sealing ring can increase the sealing performance of the piston plate 233.

[0037] In this embodiment, the first connector 227 and the second connector 236 are used to connect the first connecting pipe 226 and the second connecting pipe 235. A portable air cylinder or air pump is connected to the air nozzle 225. The gas will enter the limiting component 220 and then enter the locking component 230. The gas will enter the locking frame 231 and push the piston plate 233 to move. At the same time, the locking plate 234 will fit and lock with the top and bottom of the deformable electronic device, and finally realize the storage of the foldable electronic keyboard.

[0038] How it works: This support frame is designed for portable, foldable electronic keyboards; Form 1: When using the electronic keyboard and a support stand is required, this is the unfolded state of the device, such as... Figure 1 As shown; At this time, the placement rack 110 in the placement mechanism 100 is in the connected state, and the support component 140 is also in the unfolded state. After unfolding the foldable electronic keyboard, it is placed on the device. The bottom of the electronic keyboard is placed in multiple placement seats 210. A portable air pump or air pump can be connected to the air nozzle 225 to inflate the airbag 222. Under the action of the connecting pipe 223, the multiple airbags 222 are interconnected. Gas enters into the airbag 222, and the airbag 222 expands in the telescopic sleeve 221, causing the telescopic sleeve 221 to unfold, so that the telescopic sleeve 221 is in close contact with the electronic keyboard, realizing the stable placement of the foldable electronic keyboard. The internal air pressure can be observed using the air pressure gauge 228. After the appropriate air pressure is reached, the inflation can be stopped. Form 2: When the electronic keyboard is not in use, this device can be used for storage, such as... Figure 2 As shown; First, the foldable electronic keyboard is folded and deformed. Then, the deformed electronic keyboard is placed on one of the placement racks 110. The connection between the two placement racks 110 is released using the connecting rod 120 and the locking bolt 130. Then, the two placement racks 110 are merged together, with the electronic keyboard between the two placement racks 110. The connecting rod 120 is rotated 90 degrees, and the locking bolt 130 is rotated to connect with the threaded sleeve 111 until the locking rod 132 enters the locking hole 112. The washer 131 is tightly fitted with the connecting rod 120, achieving the initial locking of the two placement racks 110. Then, the locking tongue 240 and the locking seat 241 are used to lock the two placement seats 210. Next, deform and store the support assembly 140. First, take out the adjusting bolt 144, adjust the length of the support base 141 and the adjusting rod 142, and then lock it with the adjusting bolt 144. Rotate the support assembly 140 ninety degrees as a whole, and the connecting components deform accordingly. After the support base 141 is in place, it will be locked in the locking seat 150. The deformable locking strip 151 can increase the stability of the connection between the support assembly 140 and the locking seat 150. At the same time, under the action of external force, the locking state can be quickly released. The first connector 227 and the second connector 236 are used to connect the first connecting pipe 226 and the second connecting pipe 235. A portable air pump or air cylinder is connected to the air nozzle 225. The limiting component 220 and the locking component 230 deform simultaneously to lock the deformable electronic keyboard in the two placement racks 110. The telescopic sleeve 221 in the limiting component 220 will fit against the side of the electronic keyboard. At the same time, some gas will enter the locking frame 231. The gas will push the piston plate 233 to move, and at the same time drive the locking plate 234 to fit against the top and bottom of the deformable electronic keyboard and lock it, thus realizing the storage of the foldable electronic keyboard.

[0039] It should be noted that this folding electronic keyboard is the Becky B151pro folding electronic keyboard. This model features a 180° quick unfolding design, requires no assembly, and is ready to use right out of the box, making it ideal for beginners and portable scenarios.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
