Description

Technical Field

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

[0002] A PDA, or Personal Digital Assistant, is a highly integrated portable smart device that integrates computing, data storage, communication, and the ability to read and input specific data through various identification codes and chip reading technologies (such as barcode scanning and RFID reading and writing).

[0003] An existing patent (publication number: CN209842475U) discloses a PDA handheld terminal, which includes a handheld terminal body, a battery assembly, and a button assembly. The front of the handheld terminal body has a button mounting area, the back of the handheld terminal body has a battery mounting area, and the side of the handheld terminal body has functional holes. The battery assembly is installed in the battery mounting area and is electrically connected to the handheld terminal body. The button assembly includes at least two function buttons, each function button including a transparent element and a pattern layer, with the pattern layer disposed within the transparent element. At least two function buttons are installed in the button mounting area. This PDA handheld terminal has advantages such as less wear and tear on the button information during use, a longer button lifespan, and more convenient and reliable operation for users.

[0004] When in use, the button information of the above-mentioned terminal is not easily worn, the button life is long, and the operation is more convenient and reliable for operators. However, the overall protective performance is poor. When encountering an impact, it cannot buffer the impact force. In addition, the surface of the terminal body is relatively smooth, and it is easy to drop to the ground and be damaged during hand-holding, which affects the use of the equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multifunctional PDA handheld terminal with advantages such as improved protection and impact resistance, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional PDA handheld terminal, comprising a terminal body and a protective component, wherein the protective component includes a protective cover fitted onto the outer surface of the terminal body, the protective cover being made of rubber, and the outer surface of the protective cover having multiple integrally injection-molded protective protrusions, each of the protective protrusions having multiple buffer cavities on its upper surface, two sets of edge guards being fixedly connected to the outer surface of the protective cover, and two elastic rubber plates being fixedly connected to the upper surface of the protective cover, each of the two elastic rubber plates having multiple integrally injection-molded protrusions on its upper surface.

[0007] The above solution, through the setting of protective components, provides all-round protection for the terminal body in the instant of drop. At the same time, the buffer cavity design significantly enhances the deformation and energy absorption capacity of the rubber guard plate.

[0008] Furthermore, each of the edge guards is made of highly elastic rubber.

[0009] With the above solution, the edge guard plate is made of high elastic rubber material, which can support the protective cover and prevent it from collapsing when not in use, so that the protective cover body can maintain a stable original state under the support of the edge guard plate.

[0010] Furthermore, a hanging rope is fixedly connected to the outer surface of the protective cover, and an elastic strip of cloth is fixedly connected to the bottom end of the protective cover.

[0011] The above solution, with its lanyard and elastic strip, allows users to easily hold the terminal unit, providing multiple carrying options and improving convenience for workers.

[0012] Furthermore, a rubber contact plate is fixedly connected to the inner bottom wall of the protective cover, and the rubber contact plate is in contact with the terminal body.

[0013] By implementing the above solution and installing a rubber contact plate, the protection capability of the terminal body can be further improved, and the impact transmitted to the terminal body can be reduced.

[0014] Furthermore, a heat-conducting plate is embedded at the bottom of the rubber contact plate, and multiple heat dissipation fins are fixedly connected to the bottom of the heat-conducting plate, with all of the heat dissipation fins located inside the protective cover.

[0015] The above solution, which combines a heat-conducting plate with heat dissipation fins, can dissipate heat from the bottom of the terminal body, facilitating the removal of heat generated during the use of the terminal body.

[0016] Furthermore, the terminal body is internally equipped with a multi-functional module, which includes a wireless communication module, a positioning module, a computing module, and a storage module. A data acquisition module is located on the left side of the terminal body.

[0017] By using the above approach and setting up diversified modules, more functions can be realized in the terminal body, making the terminal body more practical.

[0018] Furthermore, the outer surface of the protective cover is provided with two sets of anti-slip textures.

[0019] By incorporating anti-slip textures into the design, the resistance between the user's hand and the protective cover can be increased, reducing the risk of the device slipping out of their hand.

[0020] Furthermore, each of the aforementioned edge guards features a hollow design.

[0021] Through the above solution, the hollow design can further increase the deformation capacity and energy absorption capacity of the rubber guard plate without sacrificing too much material. When the electronic device is dropped, the hollow part can deform, absorb the impact energy, and disperse it to a larger area, thereby effectively reducing the impact on the electronic device.

[0022] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0023] This multifunctional PDA handheld terminal features protective components. The protective protrusions provide all-around protection for the terminal body upon drop. Simultaneously, the buffer cavity design significantly enhances the deformation and energy absorption capacity of the rubber guard. Upon impact, the edge guard and protective protrusions deform rapidly, effectively absorbing and dispersing impact energy, greatly reducing the impact force on the terminal body and ensuring device safety. Furthermore, the ingenious combination of the elastic rubber plate and protrusions not only enhances the protective effect but also effectively prevents secondary rebound after the terminal body lands, avoiding additional damage to vulnerable parts such as the screen. With its excellent protective performance, energy absorption capacity, and anti-secondary rebound design, the protective components provide comprehensive and effective protection for the terminal body.

[0035] 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.

[0036] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a multifunctional PDA handheld terminal includes a terminal body 1 and a protective component 2. The protective component 2 includes a protective cover 201 sleeved on the outer surface of the terminal body 1. The protective cover 201 is made of rubber, and its outer surface has multiple integrally injection-molded protective protrusions 202. Each protective protrusion 202 has multiple buffer cavities 203 on its upper surface. Two sets of edge guards 204 are fixedly connected to the outer surface of the protective cover 201, and two elastic rubber plates 205 are fixedly connected to the upper surface of the protective cover 201. The upper surfaces of the two elastic rubber plates 205 are integrally injection-molded with multiple protrusions 206. By setting the protective component 2, the protective protrusions 202 can withstand drops. The protective assembly 2 provides all-around protection for the terminal body 1 upon impact. At the same time, the design of the buffer cavity 203 significantly enhances the deformation and energy absorption capacity of the rubber protective plate. When impacted, the edge protective plate 204 and the protective protrusion 202 can deform rapidly, effectively absorbing and dispersing the impact energy, greatly reducing the impact force acting on the terminal body 1, and ensuring equipment safety. In addition, the clever combination of the elastic rubber plate 205 and the protrusion 206 not only enhances the protective effect, but also effectively prevents the terminal body 1 from rebounding after landing, avoiding additional damage to vulnerable parts such as the screen. With its excellent protective performance, energy absorption capacity and anti-rebound design, the protective assembly 2 provides comprehensive and effective protection for the terminal body 1.

[0037] Please see Figure 1 , Figure 2 and Figure 3Each edge guard plate 204 is made of high-elasticity rubber, which can support the protective cover 201 and prevent it from collapsing when not in use. This allows the protective cover 201 to maintain its stable original state under the support of the edge guard plates 204. A hanging rope 3 is fixedly connected to the outer surface of the protective cover 201, and an elastic cloth strip 4 is fixedly connected to the bottom of the protective cover 201. The hanging rope 3 and elastic cloth strip 4 make it easy for users to hold the terminal body 1. Multiple carrying methods can improve the convenience of workers.

[0038] Please see Figure 1 , Figure 2 and Figure 4 A rubber contact plate 5 is fixedly connected to the inner bottom wall of the protective cover 201. The rubber contact plate 5 contacts the terminal body 1. The rubber contact plate 5 can further improve the protection capability of the terminal body 1 and reduce the impact transmitted to the terminal body 1. A heat-conducting plate 6 is embedded at the bottom end of the rubber contact plate 5. Multiple heat dissipation fins 7 are fixedly connected to the bottom end of the heat-conducting plate 6. The multiple heat dissipation fins 7 are all located inside the protective cover 201. The cooperation between the heat-conducting plate 6 and the heat dissipation fins 7 can dissipate heat from the bottom end of the terminal body 1, which is convenient for dissipating the heat generated by the terminal body 1 during use. A multi-functional module 8 is installed inside the terminal body 1. The multi-functional module 8 includes a wireless communication module 801, a positioning module 802, a computing module 803, and a storage module 804. A data acquisition module 805 is set at the left end of the terminal body 1. The multi-functional module 8 can realize more functions of the terminal body 1, making the terminal body 1 more practical.

[0039] Please see Figure 1 , Figure 2 and Figure 3 The outer surface of the protective cover 201 is provided with two sets of anti-slip textures 9. The anti-slip textures 9 can increase the resistance between the user's hand and the protective cover 201, reducing the risk of the terminal body 1 falling out of the hand. Each edge guard plate 204 is hollowed out. The hollowed-out design can further increase the deformation capacity and energy absorption capacity of the rubber guard plate without sacrificing too much material. When the electronic device is dropped, the hollowed-out part can deform, absorb the impact energy, and disperse it to a larger area, thereby effectively reducing the impact on the electronic device.

[0040] In this embodiment, a multifunctional PDA handheld terminal is provided with a protective component 2. The protective protrusion 202 can provide all-round protection for the terminal body 1 upon drop. At the same time, the design of the buffer cavity 203 significantly enhances the deformation and energy absorption capacity of the rubber guard plate. When impacted, the edge guard plate 204 and the protective protrusion 202 can deform rapidly, effectively absorbing and dispersing the impact energy, greatly reducing the impact force acting on the terminal body 1 and ensuring device safety. In addition, the clever cooperation between the elastic rubber plate 205 and the protrusion 206 not only enhances the protective effect but also effectively prevents the terminal body 1 from rebounding after landing, avoiding additional damage to vulnerable parts such as the screen. With its excellent protective performance, energy absorption capacity, and anti-rebound design, the protective component 2 provides comprehensive and effective protection for the terminal body 1.

[0041] The working principle of the above embodiment is as follows: First, when the user uses the device, the contact between the user's hand and the anti-slip texture 9 increases resistance and reduces the risk of the terminal body 1 slipping out of the user's hand. The suspension rope 3 and elastic strip 4 facilitate the user's grip on the terminal body 1, providing multiple carrying options and improving the convenience for workers. When the terminal body 1 is accidentally dropped, the protective protrusion 202 will be the first to contact the ground. Multiple buffer cavities 203 enhance the deformation and energy absorption capacity of the protective protrusion 202. When impacted, the edge guard plate 204 and the protective protrusion 202 deform rapidly, effectively absorbing and dispersing the impact energy, significantly reducing the impact force acting on the terminal body 1 and ensuring equipment safety. When the protective cover... When the terminal 1 bounces back twice upon contact with the ground, the protrusion 206 can contact the ground to protect the screen of the terminal body 1. This not only enhances the protective effect but also effectively prevents the terminal body 1 from bouncing back after landing, avoiding additional damage to vulnerable parts such as the screen. The protective component 2 provides comprehensive and effective protection for the terminal body 1 with its excellent protective performance, energy absorption capacity, and anti-bouncing design. During the use of the terminal body 1, the heat-conducting plate 6 and the heat dissipation fins 7 work together to dissipate heat from the bottom of the terminal body 1, facilitating the removal of heat generated during the use of the terminal body 1. The multi-functional module 8 enables more functions of the terminal body 1, making the terminal body 1 more practical.
