[0045] Embodiment one

[0046] Referring to Figure 1 The embodiment discloses a quick dismounting base, which is used in cooperation with a quick dismounting plate 6. The quick dismounting plate 6 can be regarded as a part of the outer shape of a projector device itself or be connected to the body of the projector in the form of an independent adapter accessory to realize quick dismounting or locking of the projector device and the quick dismounting base. It can be understood that the quick dismounting plate 6 in the embodiment is not limited to connecting the projector device, but can also connect electronic display devices, photographic devices and the like.

[0047] Referring to Figures 2-4 , in combination with Figure 9 , Figure 10 and Figure 13 In the embodiment, the quick dismounting base comprises a mounting base 1, which is provided with a mounting cavity. A dismounting plate control part 2, a locking control part 3 and a locking part 4 are connected through the mounting cavity. The dismounting plate control part 2 and the locking control part 3 are movably connected in the mounting cavity, and the moving directions of the two are perpendicular to each other. For example, the dismounting plate control part 2 can move up and down, and the locking control part 3 can move horizontally. The locking part 4 is rotationally connected in the mounting cavity.

[0048] In combination Figure 7 The end of the mounting base 1 is provided with a large opening 14 for communicating with the outside and the mounting cavity, and the side of the mounting base 1 is provided with a small opening 15 for communicating with the outside and the mounting cavity, the large opening 14 and the small opening 15 are used for interacting with the equipment or the user, specifically, the top of the dismounting plate control part 2 corresponds to the position of the large opening 14, and the side of the locking control part 3 corresponds to the position of the small opening 15.

[0049] The dismounting plate control part 2, the locking control part 3 and the locking part 4 are all provided with a locking position and an unlocking position, and can be switched between the locking position and the unlocking position by moving or rotating. The dismounting plate control part 2, the locking control part 3 and the locking part 4 cooperate with each other, the position state of the locking control part 3 is defined by the dismounting plate control part 2, and the position state of the locking part 4 is defined by the locking control part 3. The dismounting plate control part 2 is configured to trigger the locking control part 3 to move in the direction of the small opening 15 when moving from the unlocking position to the locking position (i.e. the locking control part 3 moves from the unlocking position to the locking position), and the locking control part 3 is configured to trigger the locking part 4 to rotate from the unlocking position to the locking position when moving in the direction of the small opening 15, so as to lock the quick dismounting plate 6.

[0050] For the convenience of understanding, the moving direction in the above embodiment is explained as follows: the moving direction of the small opening 15 is the moving direction of the far end of the mounting cavity, and the moving direction away from the small opening 15 is the moving direction of the near end of the mounting cavity.

[0051] Specifically, when switching from the unlocking state to the locking state, the quick dismounting plate 6 configured in a flat shape applies pressure to the dismounting plate control part 2, so that the dismounting plate control part 2 moves to the locking position and at the same time releases the definition of the position of the locking control part 3, so that the locking control part 3 slides in the direction of the small opening 15, and when the locking control part 3 is in the locking position, the end thereof passes through the small opening 15; at the same time, the locking control part 3 pushes the locking part 4 to rotate to the locking position in the process of sliding, and the locking position state of the locking part 4 can lock the quick dismounting plate 6.

[0052] Conversely, when switching from the locking state to the unlocking state, an external force presses the end of the locking control part 3, so that it moves from the locking position to the unlocking position, at this time, the locking control part 3 releases the definition of the rotating state of the locking part 4, so that the locking part 4 reverses to the unlocking position, thereby releasing the locking of the quick dismounting plate 6, and the dismounting plate control part 2 resets to the unlocking state and lifts the quick dismounting plate 6, or the quick dismounting plate 6 is removed to reset the dismounting plate control part 2 to the unlocking position.

[0053] As Figure 3 and Figure 4As shown, in order to simplify the structure and facilitate control, in the embodiment, the quick dismounting base further comprises elastic components connected in the mounting cavity, and the three types of one-way movements of the locking control part 3 sliding from the unlocking position to the locking position, the locking part 4 reversing from the locking position to the unlocking position, and the dismounting plate control part 2 resetting from the locking position to the unlocking position are all controlled by the corresponding elastic components, and the elastic components can adopt existing elastic structures such as springs and compression springs. Specifically, the elastic components comprise a first elastic member 51 connected to the locking control part 3, a second elastic member 52 connected to the locking part 4, and a third elastic member 53 connected to the dismounting plate control part 2.

[0054] As shown in Figure 6 and Figure 7 In a preferred embodiment, the mounting base 1 comprises an upper cover 11 and a lower cover 12 detachably connected thereto, and the mounting cavity is formed between the upper cover 11 and the lower cover 12. For example, the large opening 14 is arranged at the top of the upper cover 11, and the small opening 15 is arranged at the side of the upper cover 11 or the lower cover 12, or is formed by splicing the upper cover 11 and the lower cover 12. In order to facilitate the installation of each component in the mounting cavity, in the preferred embodiment, the mounting base 1 further comprises an auxiliary support 13 connected to the upper cover 11, and the auxiliary support 13 is configured as a round cover structure and is fixedly connected to the inner ring surface of the upper cover 11 by bolts. The lower cover 12 can be connected to the auxiliary support 13 or the upper cover 11 by bolt connection or clamping.

[0055] The preferred structure of the dismounting plate control part 2, the locking control part 3 and the locking part 4 will be described in detail below.

[0056] Combined with Figure 3 and Figure 8 , Figure 9The disassembly / assembly control unit 2 includes a disassembly / assembly control body 21 and a pin 22 connected to the side end of the disassembly / assembly control body 21. The pin 22 is used to cooperate with the locking control unit 3. The top end of the disassembly / assembly control body 21 passes through the auxiliary bracket 13 and corresponds to the position of the large opening 14 so as to cooperate with the quick disassembly / assembly plate 6. The bottom of the disassembly / assembly control body 21 is provided with a deep hole groove 211 for accommodating the third elastic element 53. The third elastic element 53 is installed in the deep hole groove 211, and the bottom end of the third elastic element 53 is connected to the lower cover 12. Correspondingly, the lower cover 12 is provided with a cylindrical mounting position 121 for installing the third elastic element 53. The lower part of the third elastic element 53 is sleeved on the cylindrical mounting position 121. It should be noted that in order to allow the disassembly / assembly control body 21 to have movement space, there should be a gap between its bottom end and the lower cover 12. At the same time, in order to prevent the disassembly / assembly control body 21 from falling out of the auxiliary bracket 13, there is a mutually cooperating blocking step 23 between its upper outer wall and the auxiliary bracket 13. When an external force is applied to the top of the disassembly and assembly control body 21, the disassembly and assembly control body 21 can move downwards and cause the third elastic element 53 to compress and deform.

[0057] To ensure the stability of the connection between the disassembly and assembly control body 21 and the pin 22 and reduce the failure rate, preferably, the pin 22 is integrally connected to the side end of the disassembly and assembly control body 21.

[0058] Furthermore, to ensure the stability of the disassembly and assembly control body 21 and its movement stability, preferably, the disassembly and assembly plate control part 2 also includes ear bodies 24 respectively fixed to both ends of the disassembly and assembly control body 21, and the ear bodies 24 are on different sides from the pin 22. The ear bodies 24 are provided with through holes arranged along their movement direction, and correspondingly, the lower cover 12 and / or auxiliary bracket 13 are provided with guide posts 122 that are adapted to the inner diameter of the through holes.

[0059] Combination Figure 3 as well as Figure 8 , Figure 10 The locking control unit 3 includes a locking control body 31, an unlocking button 32 fixed at one end thereto, and a first inclined block 33 fixed at the other end thereto. The unlocking button 32 is located at the end of the locking control body 31 near the small opening 15, and the shape of the unlocking button 32 is adapted to the small opening 15; the first inclined block 33 is used to cooperate with the locking part 4. Correspondingly, the lower cover 12 is provided with a recessed mounting position 123 for mounting the locking control body 31. The recessed mounting position 123 is constructed as a recessed structure adapted to the shape of the locking control body 31, and the recessed structure can be used for motion guidance of the locking control unit 3. Furthermore, a stop flange 312 for connecting the first elastic member 51 is also fixed on the side of the locking control body 31, and the other end of the first elastic member 51 is connected to the auxiliary bracket 13.

[0060] The locking control body 31 is provided with a slot 311 that matches the pin 22. In the unlocked state, the pin 22 is inserted into the slot 311 to limit the position of the locking control part 3. At this time, the first elastic member 51 is in a compressed state. When switching to the locked state, the pin 22 is disengaged from the slot 311 by force, releasing the position limitation of the locking control part 3. Under the action of the first elastic member 51, the locking control part 3 moves towards the small opening 15.

[0061] Furthermore, to rationally arrange the positions of the disassembly / assembly control unit 2 and the locking control unit 3, and to ensure balanced force distribution on the locking control unit 3, in this embodiment, the locking control body 31 is generally constructed as a concave shape, including a closed end and two support legs, which together form a cavity capable of accommodating the disassembly / assembly control body 21. The unlock button 32 is connected to the closed end, and two sets of first inclined blocks 33 are respectively connected to the ends of the support legs; two stop flanges 312 are respectively connected to the sides of the two support legs, and two sets of first elastic elements 51 are correspondingly provided.

[0062] Combination Figure 3 as well as Figure 8 , Figure 13 The locking part 4 is generally disposed between the two legs of the locking control body 31, and includes a locking body 41, a latch 42 connected to one end of the locking body 41, and a second inclined block 43 connected to the other end of the locking body 41. Rotating shafts 44 for rotatably engaging with the auxiliary bracket 13 are fixed on both sides of the locking body 41, and correspondingly, the auxiliary bracket 13 has rotating grooves adapted to the rotating shafts 44. The bottom of the locking body 41 has a slot 411 for installing a second elastic member 52, and the other end of the second elastic member 52 is connected via an elongated post 124 provided on the lower cover 12.

[0063] In this embodiment, the latch 42 has a predetermined length and a hook-shaped cross-section. In the locked state, the hook-shaped structure can be pressed onto the quick-release plate 6. The second inclined block 43 abuts against the bottom inclined end of the first inclined block 33. When the first inclined block 33 moves towards the small opening 15, the mutual abutment of the two inclined blocks causes the locking part 4 to rotate clockwise, compressing the second elastic member 52 and causing the latch 42 to flip and form a locked state. Corresponding to the first inclined block 33, the second inclined block 43 is also configured in two sets, respectively fixed on both sides of the end of the locking body 41. When the first inclined block 33 moves in the opposite direction, it releases the locking state limitation on the locking part 4, and the force of the second elastic member 52 causes the locking part 4 to rotate in the opposite direction and reset.

[0064] Example 2

[0065] The following text is for reference only. Figure 11 and Figure 12The quick dismounting base provided by the second embodiment is described in detail, and has substantially the same structure as the quick dismounting base provided by the first embodiment except the structure of the first inclined block 33.

[0066] As shown in Figure 11 the bottom inclined surface end of the first inclined block 33 is configured as a variable slope inclined surface 331, which comprises an initial section inclined surface 332 and a final section inclined surface 333 connected to each other, and the angles of the initial section inclined surface 332 and the final section inclined surface 333 are different, and are respectively a larger initial section inclination angle α and a smaller final section inclination angle β. 弹 Under the driving of the first elastic member 51 (F 弹 is regarded as a constant force), the locking control part 3 moves in the direction close to the small opening 15, the second inclined block 43 of the locking part 4 is in contact with the initial section inclined surface 332 and the final section inclined surface 333 of the variable slope inclined surface 331 of the first inclined block 33 in sequence, and is pushed to rotate clockwise. The second inclined block 43 of the locking part 4 is subjected to the thrust force of the variable slope inclined surface 331, which is denoted as F, and the force arm length of the contact point relative to the rotation shaft 44 of the locking part 4 is L. According to the force analysis, the initial section thrust F1 of the variable slope inclined surface 331 is F 弹 ·sin(α) -1 , the torque M1 for pushing the locking part 4 to rotate is L1 F 弹 ·sin(α) -1 , the final section thrust F2 is F 弹 ·sin(β) -1 , and the rotation torque M2 of the locking part 4 is L2 F 弹 ·sin(β) -1 . According to the geometric relationship, L2>L1 and sin(β)>sin(α), so the final section torque M2 is significantly greater than the initial section torque M1.

[0067] At the initial section of the variable slope inclined surface 331, since the inclination angle α of the initial section inclined surface 332 is large, the inclined surface only needs to be translated for a very short distance to push the locking part 4 to complete most of the angle stroke at a very fast rotating speed with a small torque M1; at the final section of the variable slope inclined surface 331, the inclined surface inclination angle β is small, and the inclined surface provides a large torque M2 with a relatively long translation distance to push the locking part 4 to lock the quick dismounting plate 6. Through the design, the variable slope inclined surface 331 can not only provide a large locking torque for the locking part 4, but also effectively control the translation stroke of the locking control part 3, shorten the pressing key stroke of the unlocking button 32, and make the user's pressing operation experience better.

[0068] Embodiment three

[0069] Based on the quick dismounting base provided by the first embodiment or the second embodiment, the present embodiment provides a quick dismounting assembly.

[0070] As shown in Figure 1 , the quick disassembly and assembly assembly includes a quick disassembly and assembly base and a quick disassembly and assembly plate 6 matched therewith.

[0071] Referring to Figure 14 , in this embodiment, the bottom of the quick disassembly and assembly plate 6 is configured with a protruding edge 61 in a circular shape. Correspondingly, the large opening 14 of the mounting base 1 is also configured as a circular structure matching the protruding edge 61, and the outer diameter of the protruding edge 61 and the inner diameter of the large opening 14 substantially match.

[0072] In combination Figure 7 , Figure 14 , in order to make the installation process of the quick disassembly and assembly plate 6 more smooth, in this embodiment, the top surface of the large opening 14 is provided with a first guide inclined surface 141 in the circumferential direction, and correspondingly, the bottom surface of the protruding edge 61 of the quick disassembly and assembly plate 6 is provided with a second guide inclined surface 611 matching the angle of the first guide inclined surface 141. When it is needed to lock the quick disassembly and assembly plate 6 with the quick disassembly and assembly base, the quick disassembly and assembly plate 6 is pressed into the large opening 14, and in the process of the quick disassembly and assembly plate 6 entering the large opening 14, the first guide inclined surface 141 and the second guide inclined surface 611 can play a guiding role, so that the quick installation positioning can be realized without precise positioning. At the same time, the circular design of the bottom of the quick disassembly and assembly plate 6 and the circular design of the large opening 14 of the mounting base 1 can realize the installation of the quick disassembly and assembly plate 6 at any angle without the need for accurate alignment, which can effectively improve the installation experience of the user.

[0073] In combination Figure 7 , Figure 13 and Figure 14 , preferably, in order to ensure the locking firmness and stability of the quick disassembly and assembly plate 6, in this embodiment, the inner hook surface of the lock catch 42 of the locking part 4 is provided with a first locking inclined surface 421, and the bottom surface of the large opening 14 at the other end relative to the locking part 4 is configured with a second locking inclined surface 142 extending radially outward, and in the locked state, the angles of the first locking inclined surface 421 and the second locking inclined surface 142 are consistent, and correspondingly, the top of the protruding edge 61 of the quick disassembly and assembly plate 6 is provided with a third locking inclined surface 612 matching the first locking inclined surface 421 and the second locking inclined surface 142 and corresponding in angle, and when locked, the inclined surfaces are in close contact with each other to generate a horizontal thrust and a vertical pressure, which can more stably fix the quick disassembly and assembly plate 6.

[0074] Embodiment Four

[0075] Based on the quick dismounting base or the quick dismounting assembly provided in the above embodiment, the embodiment provides a projection device. The projection device comprises a device main body, a quick dismounting plate 6 connected to the device main body, and a quick dismounting base matched with the quick dismounting plate 6. The quick dismounting plate 6 can be integrally connected to the device main body or connected to the device main body through an adapter. Through the cooperation of the quick dismounting plate 6 and the quick dismounting base, the quick dismounting or locking of the device main body and the quick dismounting base can be realized.

[0076] When the device main body of the projector is installed, the device main body is only needed to be vertically placed down, so that the quick dismounting plate 6 enters the large opening 14 of the quick dismounting base, the bottom surface of the quick dismounting plate 6 synchronously presses the dismounting control main body 21 downward, the latch 22 at the side end of the dismounting control main body 21 is separated from the slot 311 of the locking control main body 31, the unlocking button 32 of the locking control part 3 is triggered to pop out from the position of the small opening 15, and at the same time, the first inclined surface of the locking control part 3 pushes the locking part 4 to rotate, so that the lock catch 42 of the locking part 4 locks the quick dismounting plate 6, the other side of the quick dismounting plate 6 slides into the large opening 14 and is pressed tightly by the second locking inclined surface 142, and the quick installation in seconds is realized.

[0077] When the device main body of the projector is dismounted, the unlocking button 32 is pressed, so that the unlocking button 32 moves towards the direction of the near heart end of the installation cavity, the first inclined block 33 releases the locking state limitation of the locking part 4, the lock catch 42 of the locking part 4 is elastically reset, and the locking of the quick dismounting plate 6 is released. At this time, the device main body of the projector can be taken up, and the quick dismounting is realized. At the same time, the dismounting plate control part 2 is elastically reset, the latch 22 enters the slot 311 of the locking control main body 31, and the unlocking state switching is completed.
