Description

Technical Field

[0001] This utility model relates to the field of handheld terminal technology, specifically a drop-resistant PDA handheld terminal. Background Technology

[0002] A handheld PDA is a portable handheld electronic device, commonly known as a barcode scanner, data collector, etc. It can replace traditional laptops to automate and manage daily work and personal functions. It has the advantages of being lightweight, portable, and multifunctional, and can complete tasks conveniently and quickly. Users can easily manage their information even when they are out and about. Common types include barcode scanners, RFID readers, and POS machines.

[0003] An existing patent (publication number: CN212623818U) discloses a drop-resistant PDA handheld device, including a PDA handheld terminal device body. The PDA handheld terminal device body includes a screen part and a button part. A first protective pad and a second protective pad are respectively fitted on the outer shell of the screen part and the button part. The first protective pad and the second protective pad are integrally formed. A screen protective pad is connected to one side of the first protective pad. The screen protective pad is provided with a transparent part adapted to the screen. Velcro that can be adhered to each other is provided at corresponding positions on the screen protective pad and the shell of the screen part. By providing protective pads on the outer shell, the whole device can be effectively protected. In addition, a separate openable protective pad is provided for the screen, which provides additional protection for the screen and enhances the drop resistance.

[0004] Although the aforementioned patent provides effective protection by incorporating protective pads during use, it relies solely on these pads for cushioning, resulting in poor shock resistance for the PDA handheld terminal. Additionally, the square casing makes it unsuitable for handheld use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a drop-resistant PDA handheld terminal that is both portable and drop-resistant, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drop-resistant PDA handheld terminal, comprising a terminal body and a shell assembly adapted to the terminal body, wherein a shock-absorbing component is provided inside the shell assembly;

[0007] The outer casing assembly includes a housing and a grip, wherein the internal cavity of the housing is adapted to the terminal body;

[0008] The shock absorption assembly includes a back plate disposed inside the housing, the back plate being slidably connected to the housing, a buffer side plate disposed on the inner side of the back plate, a plurality of buffer rods disposed on the back side of the buffer side plate, the buffer rods penetrating the back plate, a partition plate being fixed to the end of the buffer rods, and a buffer spring being sleeved on the outer surface of the buffer rods, one end of the buffer spring being connected to the buffer side plate, and the other end of the buffer spring being connected to the back plate.

[0009] Furthermore, the shock absorption assembly also includes two movable plates disposed on the bottom wall of the housing. The movable plates are slidably connected to the housing. A rotating plate is hinged to the upper surface of the movable plate, and a buffer base plate is hinged to the other end of the rotating plate. Damping rods are installed on the sides of the two movable plates that are far apart from each other.

[0010] With the above solution, when a collision occurs, the terminal body transmits the vibration to the buffer base plate, and the buffer base plate transmits the vibration to the damping rod, which reduces the impact of the vibration.

[0011] Furthermore, a plurality of insert rods are fixed to the inner bottom wall of the housing. The insert rods penetrate the movable plate, and a second buffer spring is sleeved on the outer surface of the insert rod. One end of the second buffer spring is fixed to the movable plate, and the other end of the second buffer spring is fixed to the housing.

[0012] The above solution allows the moving plate to be reset by the elastic force of the second buffer spring.

[0013] Furthermore, a track groove is provided on the side of the housing, and a limit groove is provided in the middle of the track groove. A cavity is provided on the side of the terminal body, and a reset block is provided inside the cavity. A limit block corresponding to the limit groove is fixed on the outer side of the reset block.

[0014] The above scheme allows for the limiting of the limiting block via the limiting slot, thereby limiting the terminal body.

[0015] Furthermore, a reset spring is provided inside the cavity of the terminal body. One end of the reset spring is fixed to the reset block, and the other end of the reset spring is fixed to the inner bottom wall of the cavity. The size of the limiting block is smaller than the size of the limiting groove.

[0016] With the above scheme, the spring force of the reset spring can drive the reset block to reset, which in turn drives the limit block to reset. At the same time, the size of the limit block is smaller than the size of the limit groove, so that the limit block has enough distance to move when vibration occurs.

[0017] Furthermore, the side of the housing is provided with a slot, and a retaining plate is slidably connected to the outer side of the housing. The retaining plate is fixed to the back plate by a fixing block. Two retaining slots are fixed on the outer side of the housing. Cavities are provided at both ends of the retaining plate. Retaining blocks corresponding to the retaining slots are provided inside the cavities. A second reset spring and a reset telescopic rod are installed on the inner side of the retaining blocks. The other end of the second reset spring and the reset telescopic rod is fixed to the retaining plate.

[0018] The above method allows the spring force of the second reset spring to drive the locking block to reset.

[0019] Furthermore, the side of the card plate is provided with an adjustment groove, which is connected to the cavity. An adjustment plate is fixed to the outer side of the card block, and the adjustment plate is slidably connected to the adjustment groove.

[0020] The above method allows the adjustment plate to be pushed to move the locking block, thereby releasing it from the locking slot.

[0021] Furthermore, the inner wall of the housing is provided with a rubber buffer block corresponding to the front of the terminal body, and the outer surface of the grip is provided with anti-slip texture.

[0022] The above solution uses rubber buffer blocks to reduce the impact of impacts on the front of the terminal body, and anti-slip textures to prevent the handle from slipping when gripping it.

[0023] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0024] This drop-resistant PDA handheld terminal consists of a main body and a matching outer shell assembly. Inside the outer shell assembly is a shock-absorbing component. When the device is accidentally dropped, some of the vibration is transmitted to the buffer side plate, which then transmits it to the buffer spring and rubber buffer blocks to mitigate the impact. The remaining vibration is transmitted to the buffer bottom plate, which in turn transmits it to the damping rod, further reducing the impact. This design achieves drop and impact resistance. Additionally, the anti-slip texture prevents the grip from slipping, making it both portable and drop-resistant. Attached Figure Description

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a drop-resistant PDA handheld terminal includes a terminal body 1 and a shell assembly 2 adapted to the terminal body 1. The shell assembly 2 is provided with a shock-absorbing component 3. The shell assembly 2 includes a housing 201 and a grip 202. The internal cavity of the housing 201 is adapted to the terminal body 1.

[0038] Please see Figure 2 , Figure 3 and Figure 4The shock absorption assembly 3 includes a back plate 301 disposed inside the housing 201. The back plate 301 is slidably connected to the housing 201. A buffer side plate 302 is disposed on the inner side of the back plate 301. A plurality of buffer rods 303 are disposed on the back side of the buffer side plate 302. The buffer rods 303 penetrate the back plate 301. A partition plate is fixed to the end of the buffer rod 303. A buffer spring 304 is sleeved on the outer surface of the buffer rod 303. One end of the buffer spring 304 is connected to the buffer side plate 302, and the other end of the buffer spring 304 is connected to the back plate 301.

[0039] Please see Figure 3 , Figure 4 and Figure 5 The shock absorption assembly 3 further includes two movable plates 305 disposed on the inner bottom wall of the housing 201. The movable plates 305 are slidably connected to the housing 201. A rotating plate is hinged to the upper surface of the movable plate 305, and a buffer base plate 306 is hinged to the other end of the rotating plate. Damping rods 307 are installed on the opposite sides of the two movable plates 305. When a collision occurs, the terminal body 1 transmits the vibration to the buffer base plate 306, and the buffer base plate 306 transmits the vibration to the damping rods 307. The damping rods 307 reduce the impact of the vibration. Multiple insert rods 308 are fixed to the inner bottom wall of the housing 201. The insert rods 308 penetrate the movable plates 305. A second buffer spring 309 is sleeved on the outer surface of the insert rod 308. One end of the second buffer spring 309 is fixed to the movable plate 305, and the other end of the second buffer spring 309 is fixed to the housing 201. The elastic force of the second buffer spring 309 can push the movable plate 305 to reset.

[0040] Please see Figure 4 , Figure 5 and Figure 6 The housing 201 has a track groove on its side, and a limiting groove 310 is provided in the middle of the track groove. The terminal body 1 has a cavity on its side, and a reset block 311 is provided inside the cavity. A limiting block 312 corresponding to the limiting groove 310 is fixed on the outer side of the reset block 311. The limiting groove 310 can limit the limiting block 312, thereby limiting the terminal body 1. A reset spring 313 is provided inside the cavity of the terminal body 1. One end of the reset spring 313 is fixed to the reset block 311, and the other end of the reset spring 313 is fixed to the inner bottom wall of the cavity. The size of the limiting block 312 is smaller than the size of the limiting groove 310. The elastic force of the reset spring 313 can drive the reset block 311 to reset, thereby driving the limiting block 312 to reset. At the same time, the size of the limiting block 312 is smaller than the size of the limiting groove 310, so that the limiting block 312 has enough distance to move when vibration occurs.

[0041] Please see Figure 2 , Figure 4 and Figure 6 The housing 201 has a slot on its side. A retaining plate 4 is slidably connected to the outer side of the housing 201. The retaining plate 4 is fixed to the back plate 301 by a fixing block. Two retaining slots 5 are fixed on the outer side of the housing 201. Cavities are formed at both ends of the retaining plate 4. Retaining blocks 6 corresponding to the retaining slots 5 are arranged inside the cavities. A second return spring 7 and a return telescopic rod 8 are installed on the inner side of the retaining blocks 6. The other ends of the second return spring 7 and the return telescopic rod 8 are fixed to the retaining plate 4. The elastic force of the second return spring 7 can drive the retaining blocks 6 to reset. An adjustment groove is provided on the side, which is connected to the cavity. An adjustment plate 9 is fixed on the outer side of the locking block 6. The adjustment plate 9 is slidably connected to the adjustment groove. By pushing the adjustment plate 9, the locking block 6 can be moved to release the locking from the locking groove 5. The inner side wall of the housing 201 is provided with a rubber buffer block 10 corresponding to the front of the terminal body 1. The outer surface of the grip 202 is provided with anti-slip texture 11. The rubber buffer block 10 can reduce the impact of the impact on the front of the terminal body 1. The anti-slip texture 11 can prevent the grip 202 from slipping when holding the grip 202.

[0042] This embodiment of a drop-resistant PDA handheld terminal includes a terminal body 1 and a shell assembly 2 adapted to the terminal body 1. A shock-absorbing assembly 3 is installed inside the shell assembly 2. During use, when the entire unit is accidentally dropped, part of the vibration generated by the impact is transmitted to the buffer side plate 302, which then transmits it to the buffer spring 304 and, through the rubber buffer block 10, reduces the impact. The other part of the vibration is transmitted to the buffer bottom plate 306, which transmits it to the damping rod 307. The damping rod 307 reduces the impact of the vibration, thus achieving drop and impact resistance. Simultaneously, the anti-slip texture 11 prevents the handle 202 from slipping while gripping it, achieving both portability and drop resistance.

[0043] It should be noted that before use, the terminal body 1 needs to be installed inside the housing 201.

[0044] The working principle of the above embodiment is as follows: When in use, the terminal body 1 can be held directly in hand. After the terminal body 1 is installed on the housing 201, it can be used. It can be easily held by holding the handle 202. If it is accidentally dropped during use, part of the vibration generated by the impact is transmitted to the buffer side plate 302, which is then transmitted to the buffer spring 304 and the rubber buffer block 10 to reduce the impact. The other part of the vibration is transmitted to the buffer bottom plate 306, which transmits the vibration to the damping rod 307. The damping rod 307 reduces the impact of the vibration, thereby achieving the effect of drop resistance and impact resistance.

[0045] When the terminal body 1 needs to be disassembled for charging, press the limit block 312. The limit block 312 drives the reset block 311 to move, and the limit groove 310 releases the limit on the terminal body 1, so that the terminal body 1 can be separated from the housing 201. The terminal body 1 can be removed for charging.
