Description

Technical Field

[0001] The utility model belongs to the field of overturning shock absorption, and in particular relates to a shock absorption overturning mechanism. Background Art

[0002] There are many flipping mechanisms used in daily life, including the automatic flipping mechanism of the display screen in the car.

[0003] The existing display screen flipping mechanism is usually rigidly connected, in which the vibration generated by the internal motor is directly transmitted to the base frame of the flipping mechanism, causing the base frame to vibrate and generate noise. At the same time, when the flipped screen is subjected to external impact, the external impact is not buffered and directly transmitted to the base frame, causing the joints of the entire flipping mechanism to vibrate or even fall off and be damaged. Summary of the invention

[0004] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a shock-absorbing flipping mechanism. By adding a rubber pad to the fixed structure of the flipping mechanism, the vibration during the operation of the motor cannot be transmitted to the base frame, and when the outer screen is opened and receives external impact, it can effectively buffer and protect the safety of the user and the flipping mechanism.

[0005] The technical solution of the utility model: a shock-absorbing flipping mechanism, comprising a base frame, a motor and an outer screen, wherein the outer screen is fixedly connected with a rotating shaft for assisting the flipping of the outer screen, the two ends of the rotating shaft respectively extend out of the two sides of the outer screen, and the motor is drivingly connected with the rotating shaft;

[0006] A first protective shell for wrapping the motor and the shaft is provided on one side of the shaft extending out of the outer screen, and a second protective shell for wrapping the shaft is provided on the other side of the shaft extending out of the outer screen. Both ends of the shaft are rotatably connected to the first protective shell and the second protective shell respectively, the motor is fixedly connected to the first protective shell, and the first protective shell, the second protective shell and the base frame are fixedly connected by a plurality of fixing components.

[0007] The fixing assembly includes a buffer member, which is in a cylindrical structure as a whole. The buffer member includes an annular groove for clamping the first protective shell or the second protective shell, and the bottom end surface of the buffer member is in contact with the base frame.

[0008] By adopting the above technical solution, the outer screen and the motor that can cause vibration are directly connected to the first protective shell and the second protective shell, and then the first protective shell and the second protective shell are fixed to the base frame through multiple buffer parts, so that the vibration transmitted to the first protective shell and the second protective shell is buffered by several buffer parts and then transmitted to the base frame, effectively reducing the vibration transmitted to the base frame by the motor drive and the flipping of the outer screen.

[0009] The utility model is further configured as follows: the fixing assembly further includes a bolt and a gasket, and the bolt penetrates through the gasket and the buffer member and is threadedly connected to the base frame.

[0010] With the above further arrangement, the first protective shell and the second protective shell are fixed to the base frame using the bolts to prevent the first protective shell and the second protective shell from falling off, causing the motor and the outer screen to fall off, and the buffer component present at the connection between the bolt and the base frame ensures that the vibration is buffered by the buffer component before being transmitted to the base frame through the bolt.

[0011] Further configuration of the utility model: bearings for rotationally connecting the rotating shaft are fixedly arranged on the first protective shell and the second protective shell, and the first protective shell and the second protective shell are both composed of detachable and assembled shells.

[0012] With the above further arrangement, each of the shells is detachably connected to the rotating shaft and the motor and the transmission part between the motor and the rotating shaft, and then assembled into the first protective shell and the second protective shell, so that the installation of the motor and the rotating shaft is simpler and more accurate.

[0013] A further configuration of the utility model is as follows: the first protective shell and the second protective shell both include a plurality of fixing holes for clamping the annular groove, and each of the fixing holes is in a "U"-shaped structure as a whole, and the opening is tightened inwardly.

[0014] With the above further configuration, the shape of the fixing hole corresponds to the shape structure of the annular groove, so that the first protective shell and the second protective shell can be inserted into the annular groove and fit tightly, and the opening is tightened inward to effectively prevent the first protective shell and the second protective shell from falling out.

[0023] The technical scheme in this embodiment will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] It should be noted that in the description of the present invention, all directional indications (such as up, down, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. In the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0026] like Figure 1-7 As shown, a shock-absorbing flip mechanism includes a base frame 1, a motor 2 and an outer screen 3. The outer screen 3 includes a rotating shaft 4, and two ends of the rotating shaft 4 extend out of two side surfaces of the outer screen 3 respectively.

[0027] A first protective shell 5 and a second protective shell 11 are provided on the base frame 1, which are respectively located on the two sides of the rotating shaft 4 extending out of the outer screen 3. The motor 2 is fixedly connected to the first protective shell 5, and the output end of the motor 2 is transmission-connected to the rotating shaft 4, so that the rotating shaft 4 can be controlled to rotate to realize the rotation of the outer screen 3.

[0028] The first protective shell 5 and the second protective shell 11 have different shapes. The first protective shell 5 is used to wrap the motor 2, the rotating shaft 4 extending out of one side of the outer screen 3, and the transmission connection part between the motor 2 and the rotating shaft 4, and the second protective shell 11 is used to wrap the rotating shaft 4 extending out of the other side of the outer screen 3 to prevent the motor 2, the rotating shaft 4 and the transmission connection part therebetween from being damaged by direct external contact.

[0029] The first protective shell 5 and the second protective shell 11 are both separately arranged, and are composed of a plurality of detachable and assembled shells 12, wherein the shells 12 may be provided with bearing seats for fixing and installing bearings, and the first protective shell 5 and the second protective shell 11 are both rotatably connected to the rotating shaft 4 by bearings, so that the outer screen 3 and the base frame 1 can rotate, and the outer screen 3 and the motor 2 are not directly connected to the base frame 1, thereby avoiding the vibration of the outer screen 3 and the motor 2 being directly transmitted to the base frame 1.

[0030] The first protective shell 5 and the second protective shell 11 are fixedly connected by a fixing assembly, so that each protective shell 5 can be firmly fixed on the base frame 1, avoiding the first protective shell 5 and the second protective shell 11 from falling off and causing the motor 2 and the outer screen to fall apart.

[0031] The fixing assembly includes a buffer 6, a bolt 8 and a gasket 9. The buffer 6 is a cylindrical structure as a whole. The buffer 6 is provided with an annular groove 7 for clamping the first protective shell 5 or the second protective shell 11. The first protective shell 5 includes four fixing holes 10 for clamping the annular groove 7. The second protective shell 11 includes three fixing holes 10 for clamping the annular groove 7. Each fixing hole 10 is evenly distributed around the first protective shell 5 and the second protective shell 11.

[0032] A fixing component is provided at each fixing hole 10. The fixing hole (10) is generally in a "U"-shaped structure, and the opening is tightened inwardly. The size and shape of the fixing hole 10 correspond to the size, shape and structure of the annular groove 7, so that the positions of the first protective shell 5 and the second protective shell 11 where the fixing holes 10 are opened can be inserted into the annular groove 7, and the thickness of the first protective shell 5 and the second protective shell 11 at the clamping point is slightly larger than the width of the annular groove 7. The buffer 6 is made of soft rubber. When the buffer 6 is clamped with the annular groove 7, the buffer 6 can be slightly deformed to squeeze the two protective shells. The upper and lower surfaces of the annular groove 7 are in contact with the protective shells, so that the contact between the buffer 6 and the corresponding first protective shell 3 or second protective shell 11 is tighter.

[0033] The bottom end face of the buffer 6 contacts with the base frame 1, and a gasket 9 is placed on the upper end face of the buffer 6. A circular through hole is provided in the middle of the buffer 6 for passing the bolt 8. The bolt 8 passes through the gasket 9 and the buffer 6 is threadedly connected to the base frame 1 to achieve the fixation of the first protective shell 5, the second protective shell 11 and the base frame 1, and the fixing hole 10 of the "U"-shaped structure makes the buffer 6 only contact with the corresponding first protective shell 5 or second protective shell 11, and the bolt 8 does not contact the corresponding first protective shell 5 or second protective shell 11 when passing through the buffer 6.

[0034] The two protective shells are fixed to the base frame 1 by bolts 8 , and the buffer 6 existing at the connection between the bolts 8 and the base frame 1 buffers the vibration transmitted from the bolts 8 to the base frame 1 .

[0035] Specifically, the outer screen 3 and the motor 2 that can bring vibration are directly connected to the first protective shell 5 and the second protective shell 11, and then the first protective shell 5 and the second protective shell 11 are respectively fixed to the base frame 1 through multiple fixing components, and the first protective shell 5 and the second protective shell 11 are only in direct contact with the buffer 6 in the fixing component, so that the vibration transmitted to the first protective shell 5 and the second protective shell 11 passes through the buffer 6, is buffered by the buffer 6 made of soft rubber material, and then transmitted to the bolt 8, and then transmitted to the base frame 1, effectively reducing the vibration effect of the motor 2 driving and the flipping of the outer screen 3 on the base frame 1.

[0036] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that technical personnel in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
