Description

Technical Field

[0001] The invention relates to the field of power adapters, in particular to a power adapter housing and a power adapter. Background Art

[0002] A power adapter is a device that converts power supply for electronic devices and electrical appliances. It mainly includes electronic components such as a casing, a PCB board, and a transformer. It can convert input AC power into DC output, or connect a certain current-limiting resistor in series, so that it can not only charge the battery but also power various hosts.

[0003] Most of the existing power adapters are of an integrated structure, and the circuit board is mostly fixed by snapping it into the inside of the power adapter through a slot. However, this fixing method requires that the internal capacitor be forcibly removed from the inside when subsequent personnel conduct inspection and maintenance. Since the power adapter itself is mostly a plastic shell, it is very easy for the plastic parts to break when it is forcibly removed, affecting the subsequent positioning of the circuit board. In addition, the impact of the external environment on the power adapter is also very easy to cause the internal plastic parts to break, thereby reducing the overall service life.

[0004] In summary, the above structure is very likely to cause the plastic parts to break when the power adapter is forcibly removed or impacted by the outside world during actual use, affecting the subsequent positioning of the circuit board, thereby reducing the overall service life. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a power adapter housing and a power adapter to solve the technical problem that when the power adapter is forcibly removed or impacted by the outside world, the plastic parts are easily broken, affecting the limiting of the subsequent circuit board, thereby reducing the overall service life.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a power adapter housing, comprising an outer shell and a cover plate, the cover plate and the outer shell are connected by a bolt assembly, a partition is arranged inside the outer shell, and a slide groove is symmetrically provided on the top of the partition plate, and a clamping plate is slidably arranged in the slide groove, a second guide column is arranged at one end of the cover plate, and a first guide column cooperating with the second guide column is arranged on one side of the clamping plate, and a support plate is rotatably arranged on the top of the partition plate;

[0007] A special-shaped gear matched with the clamping plate is rotatably arranged in the slide groove, and a transmission mechanism is connected to one end of the special-shaped gear, and the other end of the transmission mechanism is connected to the support plate.

[0008] By adopting the above technical solution, the second guide column will be inserted into the socket on the outer shell. During this process, the second guide column will squeeze the first guide column on one side of the clamping plate, so that the first guide column drives the clamping plate to clamp and limit the circuit board. During the process of clamping the clamping plate, the tooth block at the bottom of the slider will drive the special-shaped gear to rotate, and the support rod will be rotated into the support groove through the action of the transmission mechanism. At this time, the circuit board is located in the inner part of the outer shell in a suspended setting, which further improves the overall heat dissipation effect of the device.

[0009] The present invention is further configured such that a plug hole for inserting the second guide post is provided at the front end of the housing, and one end of the plug hole is configured in an open shape.

[0010] Preferably, when the device is packaged, the cover is attached to the front end of the shell, and the second guide post on the cover will be inserted into the socket at the front end of the shell. The open setting guides the second guide post, facilitating the stable insertion of the second guide post.

[0011] The present invention is further configured such that a sliding block cooperating with the sliding groove is provided at the bottom of the clamping plate, and a tooth block meshing with the special-shaped gear is partially installed at the bottom of the sliding block.

[0012] Preferably, the stability of the sliding of the clamping plate on the top of the partition is ensured by the cooperation of the slide groove and the slider, which further improves the overall practicality of the device. At the same time, during the sliding process, the tooth block at the bottom of the slider will drive the special-shaped gear in the slide groove to rotate.

[0013] The present invention is further configured such that a clamping airbag is installed on the inner wall of the clamping plate, and the clamping airbag is detachably arranged on the clamping plate.

[0014] Preferably, during the process of the clamping plate sliding inward, the outer wall of the circuit board will first contact the clamping airbag. During this process, the clamping plate can continue to slide, effectively preventing the outer wall of the circuit board from being damaged due to excessive clamping of the clamping plate. At the same time, the clamping airbag can also protect the circuit board itself when the outer shell is impacted.

[0015] The present invention is further configured such that the transmission mechanism includes a driving disk, a transmission belt and a driven disk, the driving disk and the driven disk are connected by a transmission belt, one end of the special-shaped gear is connected to the driving disk, and one end of the driven disk is connected to the support plate.

[0016] Preferably, when the special-shaped gear rotates under the action of the tooth block, it will drive the active disk at one end to rotate, and the driven disk will follow the rotation under the action of the transmission belt, thereby achieving that the special-shaped gear will drive the support plate to flip at a certain angle, ensuring that the support plate slides stably into the inside of the support groove.

[0017] The present invention is further configured such that a support groove for the support plate to flip is provided on the top of the partition.

[0018] Preferably, when the subsequent support plate slides in under the action of the support groove, the flatness of the top of the partition is ensured, thereby further improving the overall heat dissipation effect.

[0019] The present invention is further configured such that a heat dissipation component is provided at the bottom of the partition in the housing, and an array of heat dissipation holes is provided on the partition.

[0020] Preferably, the heat of the circuit board itself during operation is extracted externally through the heat dissipation component, and further dissipated through the heat dissipation holes, thereby improving the heat dissipation effect of the circuit board during operation.

[0021] The present invention is further configured such that the outer wall of the housing is symmetrically provided with mounting holes.

[0022] As a preferred embodiment, the installation hole makes it easier for workers to install the entire housing at a designated position, thereby improving the overall practicality of the device.

[0023] A power adapter comprises a circuit board, wherein a capacitor is arranged on the top of the circuit board, and a controller and a transformer are arranged on both sides thereof.

[0024] Preferably, the capacitor on the circuit board converts the voltage from AC input to DC output, and then the voltage is adjusted by the transformer, so that the power adapter can be used to supply power to different electronic components.

[0025] The present invention is further configured such that the capacitor, the transformer and the controller are electrically connected, and the transformer itself is used to control the stable output of the voltage.

[0026] Preferably, the controller is used to ensure that the power adapter has a stable output during operation. After the electronic components are charged, the controller can automatically cut off the power supply to the electronic components, which effectively prevents power accidents from occurring.

[0027] In summary, the present invention mainly has the following beneficial effects:

[0028] 1. The present invention provides a socket on the outer shell. The staff places the circuit board on the top of the partition. When the cover is closed, the second guide post will be inserted into the socket on the outer shell. In this process, the second guide post will squeeze the first guide post on one side of the clamping plate, so that the first guide post drives the clamping plate to clamp and limit the circuit board. When the staff opens the cover for subsequent maintenance, the circuit board can be automatically released from the limit. In this process, the stability of the circuit board in the outer shell is guaranteed, and it is convenient for the staff to conduct multiple inspections and maintenance, further improving the overall practicality of the device.

[0029] 2. The present invention has a support rod rotatably arranged on the partition. In the initial state, the support rod and the partition are vertically arranged. The staff places the circuit board on the top of the support rod, and then clamps it on the clamping plate. The tooth block at the bottom of the slider drives the special-shaped gear to rotate. After the clamping is completed, the support rod is rotated into the support groove through the action of the transmission mechanism. At this time, the circuit board is located inside the outer shell and is suspended. Through the cooperation with the heat dissipation component at the bottom, the overall heat dissipation effect of the device is further improved, and the overall service life is extended.

DETAILED DESCRIPTION

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] The following describes an embodiment of the present invention based on its overall structure.

[0044] First embodiment:

[0045] See also Figure 1-Figure 10 A power adapter housing and a power adapter shown in the figure include a shell 1, a cover plate 2, a clamping mechanism, a heat dissipation mechanism and a sealing mechanism. A partition plate 6 is arranged inside the shell 1, and a support plate 9 is rotatably arranged on the top of the partition plate 6. In the initial state, the support plate 9 is arranged vertically on the top of the partition plate 6. The staff places the circuit board 16 on the top of the support plate 9, and then packages the cover plate 2 on the front end of the shell 1. A jack 7 for inserting a second guide column 20 is provided at the front end of the shell 1, and one end of the jack 7 is arranged in an open shape. When the device is packaged, the cover plate 2 is attached to the front end of the shell 1. At this time, the second guide column 20 on the cover plate 2 will be inserted into the jack 7 at the front end of the shell 1. The open-shaped setting guides the second guide column 20, which is convenient for the stable insertion of the second guide column 20.

[0046] At the same time, a slide groove 19 is symmetrically provided on the top of the partition 6, and a clamping plate 5 is slidably provided in the slide groove 19. A second guide post 20 is provided at one end of the cover plate 2, and a first guide post 4 cooperating with the second guide post 20 is provided on one side of the clamping plate 5. When the second guide post 20 is inserted inward through the insertion hole 7, the first guide post 4 at one end is squeezed. In this process, the first guide post 4 drives the clamping plate 5 at one end to move to complete the clamping work of the circuit board 16. In this process, the stability of the circuit board 16 in the housing 1 is ensured, and it is convenient for the staff to perform multiple inspections and maintenance on it, which further improves the overall practicality of the device;

[0047] The special-shaped gear 11 cooperating with the clamping plate 5 is rotatably arranged in the slide groove 19, and the bottom of the clamping plate 5 is provided with a slider 17 cooperating with the slide groove 19, and a tooth block 18 meshing with the special-shaped gear 11 is partially installed at the bottom of the slider 17. Through the cooperation of the slide groove 19 and the slider 17, the stability of the sliding of the clamping plate 5 on the top of the partition 6 is guaranteed. In this process, the overall practicality of the device is further improved. At the same time, during the sliding process, the tooth block 18 at the bottom of the slider 17 will drive the special-shaped gear 11 in the slide groove 19 to rotate, and one end of the special-shaped gear 11 is connected with a transmission mechanism 12, and the other end of the transmission mechanism 12 is connected to the support plate 9. After the clamping is completed, the support plate 9 is rotated into the support groove 10 under the action of the transmission mechanism 12. At this time, the circuit board 16 is located inside the housing 1 and is suspended.

[0048] At the same time, a heat dissipation component 8 is provided at the bottom of the partition 6 in the shell 1, and an array of heat dissipation holes is opened on the partition 6. Through the action of the heat dissipation component 8, the heat generated by the circuit board 16 during operation is extracted outward, and the heat dissipation holes further dissipate the heat. In this process, the heat dissipation effect of the circuit board 16 during operation is improved. Through the cooperation with the heat dissipation component 8 at the bottom, the overall heat dissipation effect of the device is further improved, and the overall service life is extended.

[0049] In the above embodiments, please refer to Figure 3 A clamping airbag 3 is installed on the inner wall of the clamping plate 5, and the clamping airbag 3 is detachably arranged on the clamping plate 5. When the clamping plate 5 slides inward, the outer wall of the circuit board 16 will first contact the clamping airbag 3. During this process, the clamping plate 5 can continue to slide, which effectively prevents the outer wall of the circuit board 16 from being damaged by excessive clamping of the clamping plate 5. At the same time, the clamping airbag 3 can also protect the circuit board 16 itself when the outer shell 1 is impacted.

[0050] In the above embodiments, please refer to Figure 7 A capacitor 14 is arranged on the top of the circuit board 16, and a controller 15 and a transformer 13 are arranged on both sides respectively. The capacitor 14 on the circuit board 16 converts the voltage from AC input to DC output, and then adjusts the voltage through the transformer 13, so that the power adapter is suitable for powering different electronic components. The capacitor 14, the transformer 13 and the controller 15 are electrically connected, and the transformer 13 itself is used to control the stable output of the voltage. Under the action of the controller 15, the stable output of the power adapter is guaranteed during operation. After the electronic components are charged, they can be automatically powered off through the controller 15, which effectively prevents the occurrence of power accidents.

[0051] Second embodiment:

[0052] See also Figure 5 A power adapter housing and a power adapter shown in the figure have an overall structure similar to that of the first embodiment, wherein a transmission mechanism 12 comprises an active disk, a transmission belt and a driven disk, the active disk and the driven disk are connected by a transmission belt, one end of the special-shaped gear 11 is connected to the active disk, and one end of the driven disk is connected to the support plate 9, when the special-shaped gear 11 rotates under the action of the tooth block 18, it will drive the active disk at one end to rotate, and the driven disk will follow the rotation under the action of the transmission belt, thereby realizing that the special-shaped gear 11 will drive the support plate 9 to flip at a certain angle, and at the same time, a support groove 10 for the support plate 9 to flip is provided at the top of the partition 6, and when the support plate 9 slides in subsequently under the action of the support groove 10, the flatness of the top of the partition 6 is ensured, thereby further improving the overall heat dissipation effect.

[0053] The present invention works as follows: when in use, the circuit board 16 is placed on the top of the support plate 9 in the housing 1, and then the cover plate 2 is closed to the front end of the housing 1 to seal it. The second guide post 20 on the inner side of the cover plate 2 is inserted into the insertion hole 7 at the front end of the housing 1. The first guide post 4 drives the clamping plate 5 to slide inward under the action of the second guide post 20. During this process, the clamping plate 5 performs a limiting clamping operation on the circuit board 16 on the top of the support plate 9. During this process, when the housing 1 is impacted by the outside world, the circuit board 16 is still in a limited position in the housing 1, thereby ensuring the stability of the circuit board 16 in the housing 1.

[0054] At the same time, when the clamping plate 5 slides inward, the slider 17 will drive the tooth block 18 at the bottom to move, thereby causing the special-shaped gear 11 in the slide groove 19 to rotate, and the transmission mechanism 12 will cause the support plate 9 at the bottom of the circuit board 16 in the clamped state to rotate. At this time, the support plate 9 will flip into the support groove 10, so that the circuit board 16 is located in the outer shell 1 in a suspended setting. By cooperating with the heat dissipation component 8 at the bottom, the overall heat dissipation effect of the device is further improved, and the overall service life is extended.

[0055] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
