Description

1231137 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention provides a mechanism system, especially a mechanism system capable of fixing the upper body at any angle. [Prior art]

With the development of science and technology, various institutional systems with image reading devices, such as scanners and multi-function peripherals (MFPs), are now increasingly common in institutions and the homes of ordinary users. Most of these institutional systems have two parts. The upper part is a thick upper body, which is connected to the lower housing of the mechanism system at one end and can be lifted up in the past. The upper body mostly uses the deformation force of the connected impeachment to provide its supporting force when it is opened to an angle within a specific range with the lower casing. See Figure 1. FIG. 1 is a schematic diagram of a conventional multifunctional business machine 1000. u 〇 is a housing; 120 is an upper body; 130 is a supporting device connected to the upper body 120 and the housing 110, which includes two main springs 132 and 134; wherein the upper body 120 is connected to the housing by the supporting device 110. The gravity of the upper body 120 will form a moment at the joint between the upper body 120 and the casing 110, and this moment will increase as the angle between the upper body 120 and the casing 110 decreases. The two springs 132 and 134 included in the supporting device 130 have a restoring force due to compression. This restoring force forms forces and moments in different directions for the connection between the upper body 12 and the housing 1 10, respectively. When the torque provided by the support device 130 is sufficient to overcome the gravity of the upper body 120, the angle between the body 120 and the housing 110 is a certain angle A1 (Figure 1

Page 6 1231137 V. The torque provided in the description of the invention (2) (not marked), the upper body 1 2 0 can be fixedly stopped at the position where the angle between the body 1 1 0 is A 1. However, when the angle between the upper body 120 and the housing 110 is reduced, the force and moment provided by the support device 130 will not be equal to the gravity of the upper body 120 and the formed moment. See Figure 2. Figure 2 is a schematic diagram of the conventional multifunctional business machine 100 shown in Figure 1 when the upper body 120 is turned on at a small angle. When the upper body 1 2 0 is to be closed from the opened state, the upper body 120 will hit the lower casing with a great force due to its own weight; 1 1 0; this is because the upper body 1 2 0 and the casing The body 1 10 is a small angle as shown in Figure 2. As shown in Figure 2, the gravity of the upper body 120 to the upper body 120 and the housing 110 · the moment caused by the joint becomes larger and exceeds the balance provided by the support device 130 Therefore, the upper body 1 2 0 cannot stop at this angle and continues to fall downward φ to hit the housing 110. In order to avoid this impact of gravity, the user needs to manually support the upper body 120 to close it gently from the opened state, or change the supported springs 132 and 134 so that they can provide a large balance torque, so that the upper body The body 1 2 0 can be relieved by the downward impact when it is closed from the open state. However, in this way, when the upper body 1 2 is lifted upward, it will directly spring up to the maximum open position because the spring force is too large, except that it can no longer stay at a position lower than the maximum open position. The elastic force will also cause the springs 132 and 134 and the base connected to the upper body 120 and the housing 110 to bear excessive stress and be easily damaged. In the conventional technology, the supporting device connecting the upper body and the lower case is also designed to compress the spring contained in the supporting device when the upper body is closed downward, and at this time, a card is used between the upper body and the lower case. The hooks are fixed to each other to overcome the restoring force of the spring through compression and deformation. When you want to open the upper body to release the hook, the spring will open.

Page 7 1231137 V. Description of the invention (3) The upper body can be popped up to the open position by restoring force. However, in this design, the upper body cannot stay in a position other than fully opened and closed. Except that the upper body can only stay at an angle with a certain range between the lower body and the lower body, and when the upper body is closed from the open state, the user must manually support the upper body or use a hook, etc. In the conventional technology, the deformation of the spring is used to provide the supporting force, and the connection between the upper body and the lower casing is subjected to great stress. Therefore, the design of the supporting device connecting the upper body and the lower casing is often very complicated and special materials must be used, resulting in an increase in the cost of the hardware part of such mechanism systems. [Summary of the Invention] Therefore, the main object of the present invention is to provide a mechanism system that utilizes the supporting force provided by a support shaft and a support block to closely match each other, so that the upper body can stay at any angle between the lower body and the lower housing. The angle position is to improve the problems that the conventional mechanism system cannot stay at any angle and the structure of the supporting device is complex and easily damaged. According to the patent application scope of the present invention, a mechanism system is disclosed, which includes: a housing; an upper body connected to the housing in a rotatable manner; and a support device including: a support shaft connected to The upper body; and a support block connected to the shell, the support block has a cavity therein, the support shaft passes through the support block through the cavity, and can pass along the cavity

Page 11 1231137 V. Description of the invention (Ό Column-shaped, but the cross-sectional area of one section is smaller. The section with the smaller cross-sectional area and the supporting block 6 3 4 is loose fit rather than tight fit. Figure 5 The mechanism system shown in Figure 6, Figure 7, and Figure 7 and Figure 7, no matter where the upper body is in any position, the part of the support shaft passing through the cavity of the support block is completely tightly fitted with the support block; the support shaft and the support The force and moment provided by the block to support the upper body have always remained the same, so that the upper body can stay at any position in the process from full opening to closing. However, the support shaft of the present invention can also be designed with one section having a smaller cross section. The area is as shown in the supporting shaft 6 3 2 in Figure 8. This design can have many applications. For example, when the angle between the upper body of the mechanism system and the lower housing is a small angle A 2, it usually means the upper body. To continue to close or open upwards, because the upper body stays at this small ^ degree A 2 has no effect, at this time the schematic diagram of the relative position of the support shaft and the branch block is as shown in Figure 8. Branch axis 6 3 2Upper section There is a section with the right cross-section area, and the section with the smaller cross-section area is loosely fit rather than tightly with the supporting block 6 3 4 so it will provide a smaller than the entire section completely tight. The matching force makes the upper body unable to stay at the angle 2; but because there is still a friction force between the supporting block 6 3 4 and the supporting shaft 6 3 2, it can still provide the force and moment of the upper body of the support building to make the upper body It does not impact the lower body with an excessive force, and it can be lowered gently. In this heavy invention, the above-mentioned support device is used to make the mechanism system such as multiple, work months b = machine or scanner. The body can stay on From the fully open position to the closed position, the upper body can also be able to reconcile with the opening and closing downwards, instead of impacting the underside with an excessive force like the conventional mechanism system

1231137 V. Description of the invention (8) Housing. The present invention supports the upper body by using the force and moment provided by a supporting block and the supporting shaft that are closely matched with each other. The thickness and change of the supporting shaft can also be used to adjust the force and moment of the upper body and the shell of the mechanism system The body or the upper body or its connection is not subject to the stress as the conventional multifunctional MFP. Among them, it can be closely matched with the support axis. The support block can be made of compressible and wear-resistant consumables such as rubber or polyurethane rubber (PU rubber). The support device of the present invention may include one or more support shafts, and a support block; wherein the support block needs to have a cavity relative to the one or more support shafts, or the support device of the present invention may have a plurality of support blocks to Cooperate with the plurality of supporting shafts, respectively.
