Description

Technical Field

[0001] The utility model relates to the technical field of GPS devices, and particularly relates to a handheld GPS with a protection device. Background Technique

[0002] GPS is a device that uses satellites for positioning and navigation. Among various GPS positioning devices, handheld GPS has been more widely used in many industries due to its small size, convenient carrying, and independent use. In the prior art, handheld GPS is relatively precise and has no protection measures. It is a bit inconvenient to hold it in the hand all the time, and it is impossible to tie the handheld GPS to the arm. At the same time, when the GPS is not in use, it does not have a protective effect, resulting in easy damage caused by collisions.

[0003] For example, a handheld GPS navigation terminal disclosed in the authorized patent document with the application number CN202322323128.9 includes a navigation terminal body. A data board is plugged into the right side of the navigation terminal body. A power supply module sleeved outside the bottom of the navigation terminal body is fixedly installed on the left side of the data board. A projection module sleeved outside the top of the navigation terminal body is fixedly installed on the left side of the data board. A hinge frame located above the projection module is rotatably connected to the left side of the data board. The data board is rotatably connected through the hinge frame to a polarizing mirror that passes through the front side of the navigation terminal body and extends to the power supply module. An acoustic and optical alarm component is fixedly installed on the left side of the power supply module. The acoustic and optical alarm component includes an optical signal alarm member fixed to the left side of the power supply module, and a buzzer is fixedly installed on the left side of the optical signal alarm member. This handheld GPS navigation terminal has the advantages of good observation extensibility and no impact on observation.

[0004] The above patent has the inconvenience of holding it in the hand all the time, and it is impossible to tie the handheld GPS to the arm and does not have a protective effect. Therefore, we need to provide a handheld GPS with a protection device. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a handheld GPS with a protection device. Through the wearable component, the handheld GPS body can be worn on the arm, which is convenient to use and reduces the risk of the GPS body falling off from the hand, fundamentally providing anti-fall protection. When the GPS body is not in use, the GPS body and the frame are flipped. The metal rods on both sides of the frame rotate in the slide rails, with the GPS body facing downwards. The two metal rods are adsorbed by the magnetic attraction blocks to limit the position of the frame. Among them, the surface buttons of the GPS body are embedded type and will not be accidentally touched when fitting with the wearing plate. When receiving an impact, the collision plate floats in the frame, thereby squeezing the four push rods. The push rods will drive the push blocks and the push rods to move, thus driving the piston to slide in the sealing frame. The shock-absorbing oil in the sealing frame will flow through the four circulation holes in the piston. The oil will be squeezed by the piston and flow to another chamber through the damping small holes on the piston. Since the oil has a certain viscosity, resistance will be generated when passing through the damping small holes, further absorbing the impact force. Among them, the spring located between the push block and the sealing frame plays a role in resetting, solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions: A handheld GPS with a protection device, including:

[0007] A GPS body;

[0008] And a protection component arranged at the bottom of the GPS body;

Push rods are hinged at the four corners of the top of the collision plate. Buffer components for absorbing impact force are hinged at the tops of the four push rods.

[0010] Preferably, the buffer component includes a push block hinged at one end of the push rod. A piston is fixedly installed on one side of the push block through a rod body. A sealing frame filled with shock-absorbing oil is slidably installed on the surface of the piston. Four circulation holes are opened inside the piston.

[0011] Preferably, a spring is clamped between the sealing frame and the push block, and the inside of the spring is movably sleeved on the surface of the rod body.

[0012] Preferably, a sphere is rotatably installed at the top of the push block, and a guide plate for the sphere to roll is fixedly installed on the inner wall of the frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution: a handheld GPS with a protection device, including:

[0026] GPS body 1;

[0027] and a protection member 2 provided at the bottom of the GPS body 1;

[0028] The protection member 2 includes a frame body 21 fixedly installed at the bottom of the GPS body 1. A collision plate 22 is slidably installed inside the frame body 21. Push rods 23 are hinged at the four corners of the top of the collision plate 22. Buffer members 20 for absorbing impact force are hinged at the tops of the four push rods 23.

[0029] The buffer member 20 includes a push block 201 hinged to one end of the push rod 23. A piston 202 is fixedly installed on one side of the push block 201 through a rod body 205. A sealing frame 203 filled with shock-absorbing oil is slidably installed on the surface of the piston 202. Four flow holes 204 are formed inside the piston 202;

[0030] In this embodiment, the handheld GPS body 1 can be worn on the arm through the wearable member 9, which is convenient to use and reduces the risk of the GPS body 1 falling off from the hand, fundamentally playing a role in anti-falling protection. When the GPS body 1 is not in use, the GPS body 1 and the frame body 21 are flipped. The metal rods 63 on both sides of the frame body 21 rotate in the slide rails 62, and the GPS body 1 is turned downward. The two metal rods 63 are adsorbed by the magnetic attraction blocks 7 to limit the frame body 21. The surface keys of the GPS body 1 are embedded type and will not be accidentally touched when fitting with the wearing plate 61. When receiving an impact, the collision plate 22 floats in the frame body 21, thereby squeezing the four push rods 23. The push rods 23 will drive the push block 201 and the push rod 23 to move, thereby driving the piston 202 to slide in the sealing frame 203. The shock-absorbing oil in the sealing frame 203 will flow through the four flow holes 204 in the piston 202. The oil liquid will be squeezed by the piston 202 and flow to another chamber through the damping small holes on the piston 202. Since the oil liquid has a certain viscosity, resistance will be generated when passing through the damping small holes, further absorbing the impact force. The spring 3 located between the push block 201 and the sealing frame 203 plays a resetting effect.

[0031] A spring 3 is clamped between the sealing frame 203 and the push block 201, and the inside of the spring 3 is movably sleeved on the surface of the rod body 205;

[0032] Specifically, the spring 3 located between the push block 201 and the sealing frame 203 plays a resetting effect, and the inside of the spring 3 is movably sleeved on the surface of the rod body 205 to protect the spring 3 from being bent.

[0033] A sphere 4 is rotatably installed at the top of the push block 201, and a guide plate 5 for the sphere 4 to roll is fixedly installed on the inner wall of the frame body 21;

[0034] Furthermore, the movement of the pushing block 201 drives the sphere 4 to slide on the surface of the guiding plate 5, preventing the pushing block 201 from being unevenly stressed and easily broken due to being squeezed by the push rod 23. The sphere 4 slides on the guiding plate 5, providing a certain degree of support for the pushing block 201.

[0035] It further includes a mounting member 6 for wearing the GPS body 1. The mounting member 6 includes a wearing plate 61 provided at the bottom of the GPS body 1. Slide rails 62 are fixedly installed on both sides of the top of the wearing plate 61. Metal rods 63 are slidably installed inside the two slide rails 62. One end of the two adjacent metal rods 63 is fixedly installed on the surface of the frame body 21.

[0036] Among them, protective cotton 8 is provided on both the top and bottom of the wearing plate 61. At the same time, the metal rod 63 on the surface of the frame body 21 slides within the slide rail 62, enabling the GPS body 1 to be adjusted for flipping.

[0037] In order to have a limiting and fixing effect on the GPS body 1, magnetic attraction blocks 7 are provided to adsorb the metal rods 63, facilitating the fixation of the GPS body 1 after flipping. Magnetic attraction blocks 7 for adsorbing the metal rods 63 are provided on both sides of the top of the wearing plate 61, and the magnetic attraction blocks 7 are arranged inside the slide rails 62.

[0038] Protective cotton 8 is installed on both the top and bottom of the wearing plate 61, and two groups of wearing members 9 are provided at the bottom of the wearing plate 61.

[0039] It should be noted that the protective cotton 8 is provided to protect the contact surface with the arm and the contact part with the GSP body, and the wearing members 9 are provided to wear the GPS body 1 on the arm.

[0040] This device can wear the handheld GPS body 1 on the arm through the wearing members 9, facilitating use and reducing the risk of the GPS body 1 falling off the hand, fundamentally providing anti-falling protection. When the GPS body 1 is not in use, the GPS body 1 and the frame body 21 are flipped. The metal rods 63 on both sides of the frame body 21 rotate within the slide rails 62, turning the GPS body 1 downward. The two metal rods 63 are adsorbed by the magnetic attraction blocks 7 to limit the frame body 21. The surface buttons of the GPS body 1 are embedded type and fit with the wearing plate 61 without accidental touch. When receiving an impact, the collision plate 22 floats within the frame body 21, thereby squeezing the four push rods 23. The push rods 23 drive the pushing block 201 and the push rod 23 to move, thus driving the piston 202 to slide within the sealing frame 203. The shock-absorbing oil within the sealing frame 203 flows through the four flow holes 204 within the piston 202. The oil fluid is squeezed by the piston 202 and flows through the damping small holes on the piston 202 to another chamber. Since the oil fluid has a certain viscosity, resistance will be generated when passing through the damping small holes, further absorbing the impact force. The spring 3 located between the pushing block 201 and the sealing frame 203 plays a resetting role.

[0041] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
