Description

Technical Field

[0001] This utility model relates to a calculator for learning and office supplies, and more particularly to a calculator device with a non-detachable flip structure, which is especially suitable for scenarios that require portable storage and quick switching of usage modes. Background Technology

[0002] Calculators are commonly used electronic devices in student and office settings. Their structure typically includes an operating surface with buttons (including a display screen) and a back panel. To protect calculators from wear and tear, two main protection schemes exist in the current technology, but both have significant drawbacks:

[0003] In existing technology, some calculators achieve protection through a detachable pull-out housing. The specific structure is as follows: the calculator body slides into the housing; when in use, the body is pulled out so that the keypad faces away from the bottom of the housing; when stored, the body is pushed back into the housing so that the keypad faces the bottom of the housing to cover the keypad and display screen.

[0004] Its drawbacks are: the shell and the main body are separable structures, which can easily lead to the shell being lost during frequent use, and the pull-out structure can become loose and stuck after long-term use, affecting its service life.

[0005] Another type of existing technology uses an additional flip-out or removable cover (such as a flip cover or a slider cover) installed on the calculator body to protect the keypad.

[0006] Its drawbacks are: the cover and the main body are independent parts, and there is also a risk of loss after separation; moreover, the connection between the cover and the main body is prone to wear or breakage due to frequent opening and closing, resulting in low protection reliability. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a calculator device with a non-separable flip structure.

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is: a calculator device with a non-separable flip structure, comprising:

[0009] An outer casing, the outer casing including a bottom edge and two side edges extending from both sides of the bottom edge;

[0010] A calculator, comprising a front, a back, and two sides, wherein the front is provided with buttons and a display screen;

[0011] Each of the aforementioned sides is provided with an inwardly protruding shaft post;

[0012] Each of the said sides is provided with a groove extending along its length;

[0013] The shaft connector engages with the groove, allowing the calculator to flip relative to the housing, and the calculator and the housing are inseparable.

[0014] The calculator has a use state and a protection state: in the use state, the front of the calculator faces upward and the back faces the bottom edge; in the protection state, the front of the calculator faces the bottom edge to protect the buttons and the display screen.

[0015] A further preferred embodiment of this utility model is that the length of the groove is one-third to two-thirds of the length of the side portion, so that the calculator fits the outer shell in both the use state and the protection state.

[0016] A further preferred embodiment of this utility model is: each side includes a lower half and an upper half, wherein the height of the lower half is greater than the height of the upper half;

[0017] The lower half is higher than the side portion to accommodate the calculator;

[0018] The height of the upper section is less than the height of the side section, so that the calculator can be flipped by pinching the side with the hand.

[0019] A further preferred embodiment of this utility model is that the shaft connector is located at the tail end of the lower half, i.e., close to the upper half.

[0020] A further preferred embodiment of this utility model is as follows: the inner side of the lower half is provided with a support portion, the height of which is lower than that of the shaft connecting column, for supporting the calculator so that the calculator can be placed stably inside the outer casing.

[0021] A further preferred embodiment of this utility model is that support feet are provided at the four corners of the bottom surface of the outer shell.

[0022] A further preferred embodiment of this utility model is as follows: the groove is a long, straight groove, and the shaft connector is cylindrical; the cylindrical shaft connector slides and rotates with the long, straight groove.

[0023] A further preferred embodiment of this utility model is that the two ends of the groove are closed, forming an axial limit on the shaft connecting column.

[0024] A further preferred embodiment of this invention is that the outer shell is made of one-piece injection-molded plastic.

[0025] A further preferred embodiment of this utility model is that the connection between the bottom edge and the side edge of the outer shell adopts an arc-shaped wall transition.

[0026] Compared with existing technologies, the advantages of this invention are: by setting a shaft connecting post on the side of the outer casing and forming a snap-fit ​​rotational connection with the groove on the side of the calculator, the calculator remains inseparable from the outer casing during the flipping process. This structure avoids the problems of traditional detachable flip covers being easily detached, lost, or loosened due to frequent insertion and removal, fundamentally improving the overall strength and durability of the device. The groove provides axial restraint for the shaft connecting post, resulting in better stability during flipping, reducing shaking, and contributing to reliable performance in long-term, high-frequency use scenarios.

[0027] The flip-up but non-detachable structure allows the calculator to be flipped into a protective state when not in use, with the front facing the bottom edge of the casing. This provides enveloping protection for the buttons and display screen, reducing the risk of damage to internal components from external forces such as backpack compression or drops. The flip-up structure is limited by the fit between the shaft and the groove, preventing over-rotation or jamming. This ensures smooth operation when frequently switching between active and protective states, significantly improving the overall impact resistance and safety of the device.

[0028] The fit between the pivot and the groove not only provides the calculator with a smooth flipping motion but also ensures a secure fit against the casing during use, preventing looseness from affecting the feel of the buttons. Furthermore, when protected, the calculator remains tightly fitted to the casing, making it easier to carry and store. Its simple structure, smooth flipping, and lack of the need for separate disassembly of parts allow users to quickly switch between different scenarios such as classrooms, offices, and exams, improving operational efficiency and enhancing convenience and comfort.

[0041] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0042] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0043] like Figures 1 to 4As shown, a calculator device 100 with a non-separable flip-top structure includes a housing 10 and a calculator 20 disposed within the housing 10. The housing 10 has a plate-like structure, including a bottom edge 11 and two side edges 12 extending upward from both sides of the bottom edge 11. The side edges 12 and the bottom edge 11 form an accommodating space for accommodating the calculator 20. The calculator 20 includes a front surface 21, a back surface 22, and side portions 23 located on its left and right sides. The front surface 21 is provided with buttons 01 and a display screen 02, and the back surface 22 has a flat structure for fitting against the bottom surface of the housing 10.

[0044] like Figure 5 and Figure 6 As shown, the inner sides of the two sides 12 of the outer casing 10 are respectively provided with inwardly protruding shaft connecting posts 13, which are preferably cylindrical in shape. Correspondingly, each of the two sides 23 of the calculator 20 is provided with a groove 24 extending along the length of the side 23. The groove 24 is a long strip straight groove structure, and both ends of the groove 24 are closed ends. In use, by inserting the shaft connecting post 13 into the groove 24, the calculator 20 can rotate relative to the outer casing 10; since both ends of the groove 24 are closed, the shaft connecting post 13 can slide and rotate within the groove 24 but cannot be disengaged, thus achieving an inseparable connection between the outer casing 10 and the calculator 20.

[0045] The length of the groove 24 is one-third to two-thirds of the total length of the side portion 23, allowing the calculator 20 to remain flush with the outer casing 10 when flipped to either the use or protection state, resulting in a compact overall structure and a complete appearance. In the use state, the front 21 of the calculator 20 faces upwards and the back 22 faces the bottom edge 11; in the protection state, the calculator 20 flips around the pivot post 13, so that the front 21 faces the bottom edge 11, thereby covering and protecting the buttons 01 and the display screen 02, preventing them from being bumped or contaminated when carried out.

[0046] like Figure 2 , Figure 3 As shown, each side 12 consists of a lower half 122 and an upper half 121, with the lower half 122 being taller than the upper half 121. The height of the lower half 122 is greater than the height of the side portion 23, allowing the calculator 20 to be fitted into the space formed by the outer casing 10; the height of the upper half 121 is less than the height of the side portion 23, so that the side portion 23 of the calculator 20 is partially exposed when flipped, making it easier for the user to pinch the side portion 23 with their fingers to complete the flipping operation. This structure balances protection and ease of operation.

[0047] The pivot post 13 is located at the end of the lower half 122, that is, near the upper half 121. This arrangement brings the flip axis closer to the center of gravity of the calculator 20, which helps to achieve a smooth flip trajectory and reduces the feeling of sticking when flipping.

[0048] The lower half 122 has a support portion 15 on its inner side to support the back 22 of the calculator 20, making the calculator 20 more stable when placed. Preferably, a support portion 15 is further provided on the inner side of the upper half 121, with the support portions 15 of the lower half and the upper half located at the same horizontal level, so that the calculator 20 is laid out horizontally when fully unfolded, improving operating comfort and preventing the tilt from interfering with button operation.

[0049] like Figure 7 As shown, support feet 16 are provided at the four corners of the bottom surface of the outer casing 10. The support feet 16 increase the support height of the bottom surface and improve the friction between the outer casing 10 and the table, thereby maintaining the overall stability during button operation and preventing the device from sliding.

[0050] To enhance the damping during the flipping process and prevent wobbling at any angle, a micro-protruding rib structure is preferably provided on the inner wall of the groove 24 to strengthen the frictional fit between the shaft connector 13 and the groove 24. This structure provides the calculator 20 with moderate damping during the flipping process, improving the user experience, while effectively preventing self-wobbling caused by an overly loose structure.

[0051] In addition, a guide slope is provided on the inner surface of the side 12 of the outer casing 10. The guide slope is located at the end of the calculator 20 when it is close to the use state or the protection state, and plays a guiding and limiting role, making the flip end point clearer, helping users to quickly and accurately switch the use mode and improve the efficiency of use.

[0052] The outer shell 10 is made of one-piece injection molded plastic material, which makes the overall structure strong and not easily deformed, while reducing production costs.

[0053] The non-separable flip structure provided in this embodiment ensures a secure connection between the calculator 20 and the outer casing 10, preventing the casing from being lost. At the same time, the sliding engagement between the groove 24 and the shaft connector 13 enables a stable flipping action, making it suitable for portable computing scenarios and providing a good user experience and durability.
