Description

Technical Field

[0001] This application relates to the field of charging equipment, and more particularly to a power bank with a foldable stand. Background Technology

[0002] Power banks, as portable power sources, greatly satisfy people's need to charge electronic devices when out and about, providing convenience for daily life, work, and entertainment. In related technologies, to address the convenience issue during power bank use, power banks are usually equipped with simple mounting brackets to support them at a certain angle. These brackets typically employ a one-piece rigid structure, attached to the power bank body using screws or clips. Regarding the aforementioned technologies, the inventors believe that these power bank brackets occupy a large amount of space and are not easily portable. Utility Model Content

[0003] To address the issues of bulky and inconveniently portable power bank holders, this application provides a power bank with a foldable stand.

[0004] The power bank with a foldable stand provided in this application adopts the following technical solution: A power bank with a foldable stand includes a power bank body and a stand assembly disposed on the back side of the power bank body. The stand assembly includes a first support plate, a second support plate, a third support plate, and a fourth support plate connected end to end, wherein the sum of the lengths of the first support plate and the fourth support plate is equal to the sum of the lengths of the second support plate and the third support plate. The first support plate is mounted on the back of the power bank body. The fourth support plate has a magnetic attractant, the first support plate has a first magnetic attractant portion for attracting the fourth support plate, and the third support plate has a second magnetic attractant portion for attracting the fourth support plate. The stand assembly has a supported state and a folded state. When the stand is in the supported state, the fourth support plate is attracted to the first magnetic attractant portion, and the first support plate, the second support plate, and the third support plate form a triangular structure. When the stand is in the folded state, the fourth support plate is attracted to the second magnetic attractant portion, and the back of the fourth support plate is attached to the back of the power bank body.

[0005] By adopting the above technical solution, when using the power bank, the magnetic clasp of the fourth support plate is attracted to the first magnetic part of the first support plate. At this time, the first support plate, the second support plate, and the third support plate form a triangular structure, and the bracket assembly is in a supported state. The magnetic clasp of the fourth support plate is attracted to the second magnetic part of the third support plate. Since the sum of the lengths of the first support plate and the fourth support plate is equal to the sum of the lengths of the second support plate and the third support plate, the third support plate and the fourth support plate are arranged close to the first support plate and the second support plate, and the bracket is in a folded state. This helps to improve the problem that the power bank's fixing frame occupies a lot of space and is not easy to carry.

[0006] Optionally, the back of the power bank body has a mounting protrusion for mounting the bracket assembly, and the mounting protrusion has an arrangement groove for fitting the first support plate and the fourth support plate together.

[0007] By adopting the above technical solution, the installation of protrusions and the arrangement of slots enable the bracket assembly to better integrate with the main body of the power bank, which helps to reduce the space occupied by the bracket assembly in the folded state, thereby helping to improve the overall compactness and stability of the power bank.

[0008] Optionally, the back of the first support plate is attached to the bottom of the arrangement groove.

[0009] By adopting the above technical solution, a method for attaching the bracket assembly to the main body of the power bank is disclosed. By attaching the back of the first support plate to the bottom of the arrangement groove, the bracket assembly can be stably fixed to the main body of the power bank, reducing the risk of the bracket assembly shaking or falling off during use.

[0010] Optionally, the first support plate has sliding protrusions at both ends for sliding installation of the bracket assembly, and the mounting protrusion has arrangement grooves on both sides of the arranged groove for sliding of the sliding protrusions.

[0011] By adopting the above technical solution, a sliding installation structure for the bracket assembly on the power bank body is disclosed. Sliding grooves are provided on both sides of the mounting protrusion groove on the back of the power bank body and cooperate with the sliding protrusions at both ends of the first support plate, thereby realizing the sliding installation of the bracket assembly on the back of the power bank body, which helps to improve the flexibility of the bracket assembly in disassembly and assembly.

[0012] Optionally, the mounting protrusion has a snap-fit ​​structure at the top of the arrangement groove for limiting the two ends of the first support plate. The snap-fit ​​structure includes a deformable part with one end connected to the mounting protrusion and having elasticity, and an abutting part arranged at the movable end of the deformable part and abutting against the top of the arrangement groove.

[0013] By adopting the above technical solution, the snap-fit ​​structure can limit the two ends of the first support plate, and the first support plate can be stably installed in the arrangement slot through elastic snap-fit, which helps to enhance the connection stability between the bracket assembly and the power bank body.

[0014] Optionally, the second support plate includes a first telescopic plate with one end connected to the first support plate and a second telescopic plate with one end connected to the third support plate and the other end slidably arranged on the first telescopic plate; the first telescopic plate has a telescopic groove on the side facing the second telescopic plate for the movable end of the second telescopic plate to slide.

[0015] By adopting the above technical solution, the specific structure of the second support plate is disclosed. The second support plate is set as a telescopic structure composed of a first telescopic plate and a second telescopic plate. The telescopic groove is used to realize the sliding of the second telescopic plate on the first telescopic plate, thereby adjusting the length of the second support plate. This helps to adjust the angle and height of the bracket assembly in the supported state, further improving the convenience and flexibility of using the power bank.

[0016] Optionally, the second telescopic plate has mounting screw holes penetrating its inner and outer surfaces, and a sliding member is arranged in the mounting screw holes for horizontal sliding of the second telescopic plate; the sliding member has a sliding protrusion on the side facing the first telescopic plate, and the first telescopic plate has a strip groove along its length at the bottom of the telescopic groove for sliding arrangement of the sliding protrusion.

[0017] By adopting the above technical solution, the sliding component and the strip groove have a guiding effect on the horizontal sliding of the second telescopic plate, further improving the stability of the second telescopic plate sliding horizontally along the telescopic groove.

[0018] Optionally, the outer edge of the second telescopic plate has a damping structure that conforms to the sidewall of the telescopic groove.

[0019] By adopting the above technical solution, the damping structure can increase the resistance when the second telescopic plate slides in the telescopic groove, which helps to improve the stability of the telescopic operation of the second telescopic plate.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. A power bank with a foldable stand, comprising a power bank body and a stand assembly disposed on the back side of the power bank body; when using the power bank, the magnetic piece of the fourth support plate is attracted to the first magnetic part of the first support plate, at which time the first support plate, the second support plate and the third support plate form a triangular structure, and the stand assembly is in a supported state; the magnetic piece of the fourth support plate is attracted to the second magnetic part of the third support plate, since the sum of the lengths of the first support plate and the fourth support plate is equal to the sum of the lengths of the second support plate and the third support plate, at which time the bottom surfaces of the third support plate and the fourth support plate are arranged to be in contact with the top surfaces of the first support plate and the second support plate, and the stand is in a folded state, which helps to improve the problem that the fixed frame of the power bank occupies a lot of space and is not easy to carry; 2. By setting mounting protrusions and arrangement slots, the bracket assembly can better integrate with the main body of the power bank, which helps to reduce the space occupied by the bracket assembly in the folded state, thereby helping to improve the overall compactness and stability of the power bank; 3. By setting the second support plate as a telescopic structure composed of the first telescopic plate and the second telescopic plate, it is helpful to adjust the angle and height of the bracket assembly in the supported state, further improving the convenience and flexibility of using the power bank.

[0029] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0030] This application discloses a power bank with a foldable stand.

[0031] Example 1 Reference Figure 1 and Figure 2 The power bank with a foldable stand includes a power bank body 1 and a stand assembly 2 disposed on the back side of the power bank body 1. The power bank body 1 includes a mounting housing 11, a battery 12 disposed within the mounting housing 11, and a circuit board 13 disposed within the mounting housing 11 and connected to the battery 12. The back of the mounting housing 11 has a mounting protrusion 14 for mounting the stand assembly 2, and the mounting protrusion 14 has an arrangement groove 141 for fitting the stand assembly 2 together.

[0032] Reference Figure 3 The bracket assembly 2 includes a first support plate 21, a second support plate 22, a third support plate 23, and a fourth support plate 24 connected end to end. The sum of the lengths of the first support plate 21 and the fourth support plate 24 is equal to the sum of the lengths of the second support plate 22 and the third support plate 23. The fourth support plate 24 has a magnetic suction piece 241. The first support plate 21 has a first magnetic suction part 211 for attracting the fourth support plate 24. The third support plate 23 has a second magnetic suction part 231 for attracting the fourth support plate 24. In this embodiment, the first support plate 21 is adhered to the bottom of the arrangement groove 141 with adhesive, allowing the bracket assembly 2 to be stably fixed to the power bank body 1, reducing the risk of the bracket assembly 2 shaking or detaching during use.

[0033] Reference Figure 3The bracket assembly 2 has a supported state and a folded state. When the bracket is in the supported state, the fourth support plate 24 is attracted to the first magnetic part 211, and the first support plate 21, the second support plate 22, and the third support plate 23 form a triangular structure. When the bracket is in the folded state, the fourth support plate 24 is attracted to the second magnetic part 231, and the back of the fourth support plate 24 is attached to the bottom of the arrangement groove 141. Among them, the first support plate 21, the second support plate 22, and the third support plate 23 are all metal plates, so that the bracket assembly 2 can effectively support the power bank body 1 when it is in the supported state.

[0034] Reference Figure 3 and Figure 4 The second support plate 22 is a telescopic plate structure. The telescopic plate structure includes a first telescopic plate 221 connected at one end to the first support plate 21, and a second telescopic plate 222 connected at one end to the third support plate 23 and slidably disposed on the first telescopic plate 221. The first telescopic plate 221 has a telescopic groove 2211 on the side facing the second telescopic plate 222 for sliding the movable end of the second telescopic plate 222. By using the telescopic groove 2211 to allow the second telescopic plate 222 to slide on the first telescopic plate 221, the length of the second support plate 22 can be adjusted, thereby adjusting the angle and height of the support assembly 2 in the supported state. The outer edge of the second telescopic plate 222 has a damping structure 2221 arranged against the side wall of the telescopic groove 2211, increasing the resistance when the second telescopic plate 222 slides within the telescopic groove 2211, and helping to improve the stability of the telescopic operation of the second telescopic plate 222. In this embodiment, the damping structure 2221 is a rubber strip.

[0035] Reference Figure 3 and Figure 5 The second telescopic plate 222 has mounting screw holes 2222 penetrating its inner and outer surfaces. A sliding member 223 is arranged at the mounting screw holes 2222 for horizontal sliding of the second telescopic plate 222. The sliding member 223, along the direction near the first telescopic plate 221, includes a bolt head 2231 threaded onto the mounting screw hole 2222, and a sliding protrusion 2232 with one end connected to the bolt head 2231 and the other end facing the first telescopic plate 221. The first telescopic plate 221 has a strip groove 2212 along its length at the bottom of the telescopic groove 2211 for sliding the sliding protrusion 2232, thus guiding the horizontal sliding of the second telescopic plate 222 and further improving the stability of the second telescopic plate 222's horizontal sliding along the telescopic groove 2211.

[0036] The implementation principle of Example 1 is as follows: When using the power bank, the magnetic 241 of the fourth support plate 24 is attracted to the first magnetic part 211 of the first support plate 21. At this time, the first support plate 21, the second support plate 22 and the third support plate 23 form a triangular structure, and the bracket assembly 2 is in a supported state. The magnetic 241 of the fourth support plate 24 is attracted to the second magnetic part 231 of the third support plate 23. Since the sum of the lengths of the first support plate 21 and the fourth support plate 24 is equal to the sum of the lengths of the second support plate 22 and the third support plate 23, the third support plate 23 and the fourth support plate 24 are arranged close to the first support plate 21 and the second support plate 22. The bracket is in a folded state, which helps to improve the problem that the power bank fixing frame occupies a lot of space and is not easy to carry.

[0037] Example 2 The power bank with a foldable bracket in this application is identical to that in Embodiment 1 except for the way the bracket assembly 2 is installed on the back of the power bank body 1.

[0038] Reference Figure 6 and Figure 7 The first support plate 21 has sliding protrusions 212 at both ends for sliding installation of the bracket assembly 2. The mounting protrusion 14 has arrangement grooves 142 on both side walls of the arrangement groove 141 for sliding of the sliding protrusions 212. The mounting protrusion 14 has a snap-fit ​​structure 15 at the top of the arrangement groove 142 for limiting the two ends of the first support plate 21. The snap-fit ​​structure 15 includes a deformable portion 151 with one end connected to the mounting protrusion 14 and having elasticity, and an abutting portion 152 arranged at the movable end of the deformable portion 151 and abutting against the bottom of the arrangement groove 142. A certain angle is formed between the deformable portion 151 and the abutting portion 152, so that the abutting portion 152 always tends to abut against the side wall of the arrangement groove 142.

[0039] Reference Figure 7 When installing the bracket assembly 2, first align the sliding protrusions 212 at both ends of the first support plate 21 with the arrangement groove 142 and insert them into the arrangement groove 142 along the length direction of the arrangement groove 142. Finally, insert the first support plate 21 into the gap between the snap-fit ​​structure 15 and the mounting protrusion 14, and clamp and fix the first support plate 21 by the abutment part 152, thereby realizing the sliding installation of the bracket assembly 2 on the power bank body 1.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
