[0026] See also Figures 1 to 5 An embodiment of the utility model provides a handheld temperature measuring device, including a temperature measuring unit and a display screen structure 10 electrically connected to the temperature measuring unit. The temperature measuring unit is used to measure temperature, and the display screen structure 10 is used to display the temperature measured by the temperature measuring unit.
[0027] The display screen structure 10 includes a main body shell 12 and a display screen 14. The display screen 14 is connected to the temperature measuring unit and is used to display the temperature. The display screen 14 is mounted on the main body shell 12. The main body shell 12 is provided with an avoidance hole 16 corresponding to the display screen 14. The avoidance hole 16 is arranged opposite to the display screen 14, so as to avoid the display screen 14 from being blocked by the main body shell 12.
[0028] A panel 18 is provided on one side of the main body shell 12 away from the display screen 14 . The panel 18 is fitted and fixed to the main body shell 12 to achieve a certain protective and decorative effect.
[0029] The main body shell 12 is provided with a buffer structure 20 at the position connected to the display screen 14. The buffer structure 20 abuts against the display screen 14, and the buffer structure 20 includes a buffer cavity 22. When the handheld temperature measuring device is impacted by falling, the buffer structure 20 can absorb the impact force and deform by compressing the buffer cavity 22 to achieve soft contact with the display screen 14, forming a buffer effect on the display screen 14, thereby reducing the risk of damage to the display screen 14 and improving the anti-fall performance of the handheld temperature measuring device.
[0030] Preferably, the display screen 14 can move relative to the main shell 12, that is, the display screen 14 and the main shell 12 are not relatively fixed. When the handheld temperature measuring device is impacted and the buffer structure 20 is deformed, the display screen 14 can move relative to the main shell 12. After the impact force disappears, the buffer structure 20 returns to the state before the impact and drives the display screen 14 to return to its original position, so that soft contact is formed between the display screen 14 and the buffer structure 20; or, the display screen 14 is relatively fixed to the main shell 12, but the contact part of the display screen 14 and the buffer structure 20 has a certain elasticity and can be deformed, so that the display screen 14 can deform with the buffer structure 20 when it is impacted. After the impact disappears, the display screen 14 and the buffer structure 20 return to their initial state under the action of their own elastic force, and soft contact can also be formed.
[0031] The display screen 14 includes a display layer 24 and a protective layer 26. The protective layer 26 is attached to one side of the display layer 24. The buffer structure 20 abuts against the protective layer 26, that is, the protective layer 26 separates the display layer 24 from the buffer structure 20 to avoid direct contact. Specifically, the buffer structure 20 abuts against the edge of the protective layer 26. By configuring the display screen 14 to be a stacked display layer 24 and a protective layer 26, the protective layer 26 is located outside the display layer 24 to protect the display layer 24. At the same time, the protective layer 26 can also be used for decorative effects and fixing operations.
[0032] It can be understood that the display screen 14 can be a touch screen with a touch function or a non-touch screen without a touch function. When the display screen 14 is a touch screen, the protective layer 26 acts as the touch layer (i.e., TP layer) of the display screen 14, that is, the protective layer 26 not only has the function of protecting the display layer 24, but also has a touch function; when the display screen 14 is a non-touch screen, the protective layer 26 has no touch function, and at this time the protective layer 26 mainly plays the role of protecting the display layer 24.
[0033] The buffer structure 20 includes an airbag 28 abutting against the display screen 14, and a buffer cavity 22 is provided inside the airbag 28. The airbag 28 is made of elastic material such as soft rubber, and abuts against the protective layer 26 of the display screen 14. The end surface of the airbag 28 abutting against the protective layer 26 serves as a buffer load absorbing surface. When the display screen 14 is impacted, the impact force acts on the buffer load absorbing surface, and the airbag 28 can be deformed by squeezing the air in the buffer cavity 22, thereby forming a buffer effect.
[0034] The surface of the airbag 28 close to the display screen 14 is a plane, and the surface of the display screen 14 in contact with the airbag 28 is also a plane, so that the surface of the airbag 28 close to the display screen 14 fits together with the display screen 14 to increase the contact area between the airbag 28 and the display screen 14.
[0035] It can be understood that the buffer cavity 22 can be a closed space or an open space. In this embodiment, the buffer structure 20 further includes a connecting hole 30 provided on the side of the airbag 28 away from the display screen 14. The connecting hole 30 connects the buffer cavity 22 with the outside. When the airbag 28 is subjected to impact force, the air in the buffer cavity 22 is discharged to the outside of the airbag 28 through the connecting hole 30, thereby reducing the deformation difficulty of the airbag 28.
[0036] The specific number of the airbags 28 is not limited, and can be one or more. In this embodiment, the number of the airbags 28 is multiple, and the multiple airbags 28 are arranged around the outer periphery of the avoidance hole 16. The multiple airbags 28 are arranged at intervals and are spaced from the avoidance hole 16. By arranging multiple airbags 28 around the avoidance hole 16, each airbag 28 contacts the display screen 14, increasing the contact area between the buffer structure 20 and the display screen 14, making the overall force on the display screen 14 more uniform, and further reducing the risk of damage to the display screen 14.
[0037] Specifically, the outer contour of the display screen 14 is square, and the multiple airbags 28 are arranged at intervals along the square track. The four sides of the display screen 14 are in contact with some of the airbags 28, so that the display screen 14 is subjected to more uniform force as a whole when impacted.
[0038] In one embodiment, the buffer structure 20 further includes a seal 32, which protrudes from the same side of the main shell 12 as the airbag 28, and is sealed and fitted with the display screen 14, that is, the seal 32 is sealed and fitted with the protective layer 26 of the display screen 14. The seal 32 is made of an elastic material such as soft rubber, so that it fits with the display screen 14, which can not only further play a buffering effect, but also achieve sealing, and play a waterproof and dustproof role.
[0039] The height of the seal 32 is greater than the height of the airbag 28 before assembly. Therefore, during the assembly process, the seal 32 first contacts the display screen 14. After the display screen 14 is installed to the preset position, the display screen 14 squeezes the seal 32 to deform the seal 32, and the height of the seal 32 becomes smaller, and finally the seal 32 and the airbag 28 are both in contact with the display screen 14. At this time, the seal 32 is tightly pressed against the display screen 14 through deformation to form a better sealing effect.
[0040] Preferably, the sealing member 32 is annular in shape to provide a better protective effect.
[0041] The relative positions of the seal 32 and the airbag 28 are not limited. For example, the airbag 28 can be located outside the seal 32 or inside the seal 32. In this embodiment, a plurality of airbags 28 are located outside the seal 32 and spaced apart from the seal 32.
[0042] In one embodiment, the main body shell 12 includes a supporting shell 34 and a buffer shell 36, the buffer shell 36 is sleeved on the outer side of the supporting shell 34, the avoidance hole 16 includes a first avoidance hole 38 provided in the supporting shell 34 and a second avoidance hole 40 provided in the buffer shell 36, the first avoidance hole 38 and the second avoidance hole 40 are opposite to and connected, and the display screen 14 is installed in the supporting shell 34 and is located on the side of the first avoidance hole 38 away from the second avoidance hole 40.
[0043] The hardness of the supporting shell 34 is greater than that of the buffer shell 36. Specifically, the supporting shell 34 is made of hard rubber and has a relatively large overall strength for installation of the display screen 14. The buffer shell 36 is made of soft rubber and has a certain elasticity. The buffer shell 36 is sleeved on the outside of the supporting shell 34 to form a preliminary buffering effect when the handheld temperature measuring device is impacted, absorb part of the impact force, and further reduce the risk of damage to the display screen 14.
[0044] The connection method between the support shell 34 and the buffer shell 36 is not limited. In one embodiment, the support shell 34 and the buffer shell 36 are integrally formed by a two-color molding process.
[0045] A mounting groove 42 is provided on one side of the support shell 34 away from the first avoidance hole 38 . The mounting groove 42 surrounds the outer periphery of the first avoidance hole 38 and is connected to the first avoidance hole 38 . The display screen 14 is mounted in the mounting groove 42 . Specifically, the edge of the display screen 14 is received in the mounting groove 42 .
[0046] It can be understood that the buffer structure 20, namely the airbag 28 and the seal 32, can be arranged on the buffer shell 36 or on the support shell 34, as long as it can contact the display screen 14. At the same time, the connection method between the buffer structure 20 and the support shell 34 or the buffer shell 36 is not limited, and can be integrally formed or assembled separately. In this embodiment, the buffer structure 20 is arranged on the buffer shell 36, and the buffer structure 20, namely the airbag 28 and the seal 32, are integrally formed with the buffer shell 36. The buffer shell 36, the airbag 28 and the seal 32 are all made of soft rubber, so they can be formed into one piece by injection molding, eliminating the assembly and fixing process and reducing the difficulty of production.
[0047] In this embodiment, the airbag 28 is disposed in the buffer shell 36 and is located at the outer periphery of the second avoidance hole 40. The support shell 34 is provided with a through hole 44 on the outer periphery of the first avoidance hole 38. The through hole 44 and the first avoidance hole 38 are spaced apart from each other. The buffer shell 36 is sleeved on the side of the support shell 34 away from the display screen 14. The airbag 28 passes through the through hole 44 on the support shell 34 and abuts against the display screen 14.
[0048] Specifically, there are multiple airbags 28 and perforations 44 in one-to-one correspondence, and each airbag 28 abuts against the display screen 14 after passing through a corresponding perforation 44 .
[0049] The seal 32 is disposed on the buffer shell 36 and surrounds the outer circumference of the second avoidance hole 40 . The seal 32 is located between the airbag 28 and the second avoidance hole 40 . The seal 32 passes through the first avoidance hole 38 on the support shell 34 and then seals and fits with the display screen 14 .
[0050] Specifically, the support shell 34 and the buffer shell 36 both include a surrounding wall and a support plate. The surrounding wall is roughly annular, and the support plate is fixed to the inner side of the corresponding surrounding wall. The surrounding wall of the buffer shell 36 is wrapped around the outer side of the surrounding wall of the support shell 34, and the support plate of the buffer shell 36 is located on the outer side of the support plate of the support shell 34 and fits each other. The panel 18 is arranged on the outer side of the support plate of the buffer shell 36, the buffer structure 20 is arranged on the support plate of the buffer shell 36, the display screen 14 is installed on the support plate of the support shell 34, and the avoidance hole 16 passes through the support shell 34 and the support plate of the buffer shell 36.
[0051] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
