Description
Technical Field
[0001] The present invention relates to the field of photographic equipment, and in particular to an OIS motor anti-damping glue protection structure, an OIS motor, a photographic device, and an electronic product. Background Art
[0002] The existing OIS anti-shake motor mainly includes a voice coil motor body and an anti-shake mechanism connected to the voice coil motor body, and the existing OIS motor anti-shake mechanism mainly includes translation type, axis shift type, memory metal type, suspension line type, etc.; the existing motor body mainly includes a carrier, a coil, a magnet, an upper spring, a lower spring, etc.
[0003] An OIS motor using a suspension wire structure is generally provided with a bracket connected to the voice coil motor body, and a suspension wire is set between the bracket and the OIS motor base. The deflection anti-shake function of the voice coil motor body is realized by the extension and retraction of the suspension wire.
[0004] In order to prevent the voice coil motor body from shaking after the suspension line is extended or retracted, damping glue is generally provided to further provide a damping and anti-shake function. The damping glue is located between the bracket and the base, and the damping glue is located at the corners of the base.
[0005] The existing bracket and eyelet line point damping glue structure is prone to glue splicing and debonding during the motor cleaning and vibration process, which can easily cause the spun damping glue to be applied to the outer wall of the bracket. During the OIS anti-shake movement, the damping glue on the side wall of the bracket is in contact with the outer shell (surrounding components). The damping glue still has a certain viscosity after curing. In addition, since the OIS anti-shake motor has a small structure and light weight, there is a small force between the damping glue and the outer shell or surrounding components, which is enough to affect the anti-shake performance of the OIS anti-shake motor, resulting in product defects and poor stability.
[0006] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Summary of the invention
[0007] The purpose of the present invention is to provide an OIS motor anti-damping glue protection structure, an OIS motor, a camera device, and an electronic product. The damping glue is avoided by an avoidance groove so that the damping glue located on the inner wall of the outer shell does not contact the bracket, effectively avoiding the damping glue being thrown between the side wall of the bracket and the outer shell, resulting in defective OIS anti-shake motors, thereby improving the product qualification rate.
[0008] The above technical objectives of the present invention are achieved through the following technical solutions: an OIS motor anti-damping glue protection structure, comprising a shell, a base arranged on the shell, a bracket connected to the voice coil motor body, a suspension wire arranged between the voice coil motor body and the base, and damping glue arranged between the base and the bracket and located at the corner position of the base, the corner position of the bracket is provided with a receiving groove to facilitate the movement of the suspension wire, the side wall of the bracket is provided with an avoidance groove to prevent the damping glue from being thrown to the side wall of the bracket and protruding from the side wall, the avoidance groove is close to the corner position of the bracket, and the avoidance groove passes through the lower surface of the bracket, the avoidance groove is connected with the receiving groove, the damping glue is thrown out and falls to the corresponding position of the avoidance groove or the shell, so as to prevent the damping glue from being thrown out and adhering to the bracket or the shell and contacting the relative shell or bracket.
[0009] The present invention is further configured as follows: the base is provided with a fixing hole for the suspension wire to pass through, the fixing hole is funnel-shaped, and the aperture of the fixing hole toward one end of the bracket is larger than the aperture of the end away from the bracket, and the fixing hole is filled with damping glue.
[0010] The present invention is further configured as follows: a welding notch is provided at one end of the base facing away from the bracket, the welding notch is connected to the fixing hole, a power-connecting metal sheet connected to the power terminal of the OIS motor is provided on the bottom surface of the welding notch, and a lower tin block for fixing the suspension wire is provided in the welding notch.

[0012] The lower end surface of the bracket is provided with a glue storage groove for the glue between the lower spring and the bracket to flow into. The glue storage groove is located at the accommodating groove position. The glue storage groove can be connected with the avoidance groove. The glue storage groove is recessed in the side wall of the bracket. After the damping glue is thrown out and falls to the glue storage groove or the position of the glue storage groove corresponding to the outer shell, the damping glue thrown out is prevented from adhering to the bracket or the outer shell and contacting the relative outer shell or bracket.

[0018] In summary, the present invention has the following beneficial effects:
[0019] During the assembly process of the OIS anti-shake motor, when the bracket is spun and cleaned, the bracket vibrates relative to the base, which can easily cause the damping glue to be thrown out.

When the damping glue falls into the avoidance groove, due to the existence of the avoidance groove, the damping glue in the avoidance groove is prevented from protruding from the side wall surface of the bracket, thereby preventing the damping glue from contacting the inner wall of the outer shell during shaking or movement of the bracket. When the damping glue falls to the position of the avoidance groove corresponding to the outer shell, the damping glue is avoided by the avoidance groove, so that the damping glue located on the inner wall of the outer shell does not contact the bracket; it is effectively avoided that the damping glue is thrown between the side wall of the bracket and the outer shell, which leads to defective OIS anti-shake motors, thereby improving the qualified rate of products.
[0020] The welding notch plays a role of giving way, so as to prevent the lower tin block from protruding from the lower end surface of the base when welding the lower tin block, and the welding notch is filled with the lower tin block to facilitate fixing the lower tin block.
[0021] When the damping glue falls into the glue storage slot, the existence of the glue storage slot prevents the damping glue in the glue storage slot from protruding from the side wall surface of the bracket, thereby preventing the damping glue from contacting the inner wall of the outer shell during shaking or movement of the bracket. When the damping glue falls to the position of the outer shell corresponding to the glue storage slot, the damping glue is avoided by the glue storage slot, so that the damping glue on the inner wall of the outer shell does not contact the bracket, thereby further preventing the damping glue from being thrown out and affecting the normal use of the OIS anti-shake motor.
[0022] The suspension wire is conveniently fixed by clipping it into the slot, and the suspension wire is effectively fixed to the upper spring by the tinning block. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with diagrams and specific embodiments.
[0030] Embodiment 1, as Figures 1 to 4 As shown, an OIS motor anti-damping glue protection structure proposed by the present invention includes a housing 1, a base 2 installed on the housing 1, a bracket 3 connected to the voice coil motor body, a suspension wire 4 installed between the voice coil motor body and the base 2, and a damping glue installed between the base 2 and the bracket 3 and located at the corner of the base 2, and the damping glue can be fixed at the position of the base 2. A receiving groove 5 is provided at the corner of the bracket 3 to facilitate the movement of the suspension wire 4, and an avoidance groove 6 is provided on the side wall of the bracket 3 to prevent the damping glue from being thrown to the side wall of the bracket 3 and protruding from the side wall. The avoidance groove 6 is close to the corner of the bracket 3, and the avoidance groove 6 passes through the lower surface of the bracket 3, and the avoidance groove 6 is connected to the receiving groove 5. The avoidance groove 6 is close to the damping glue position, and the avoidance groove 6 can be provided on both side walls adjacent to the corner of the bracket 3.
[0031] During the assembly process of the OIS anti-shake motor, when the bracket 3 is dried and cleaned, the bracket 3 vibrates relative to the base 2, which easily causes the damping glue to be thrown out, and the thrown damping glue will fall to the surrounding position of the damping glue; the damping glue is thrown out and falls to the avoidance groove 6 or the corresponding position of the shell 1, so as to prevent the thrown damping glue from contacting the bracket 3 and the shell 1 at the same time, that is, the damping glue may fall into the avoidance groove 6 or fall to the position of the shell 1 corresponding to the avoidance groove 6. When the damping glue falls into the avoidance groove 6, due to the existence of the avoidance groove 6, the damping glue in the avoidance groove 6 is prevented from protruding from the side wall surface of the bracket 3, thereby preventing the damping glue from contacting the inner wall of the shell 1 during the shaking or movement of the bracket 3. When the damping glue falls to the position of the shell 1 corresponding to the avoidance groove 6, the damping glue is avoided by the avoidance groove 6, so that the damping glue located on the inner wall of the shell 1 does not contact the bracket 3; it is effectively prevented that the damping glue is thrown between the side wall of the bracket 3 and the shell 1, resulting in defective OIS anti-shake motors, thereby improving the qualified rate of the products.
[0032] Embodiment 2 is further configured based on embodiment 1, such as Figures 1 to 4 As shown, the base 2 is provided with a fixing hole 7 for the suspension wire 4 to pass through, the fixing hole 7 is arranged in a funnel shape, and the aperture of the fixing hole 7 facing the bracket 3 is larger than the aperture of the end away from the bracket 3, and the fixing hole 7 is filled with damping glue. By filling the fixing hole 7 with damping, the damping glue can be positioned and fixed, and the risk of the damping glue being thrown out can be effectively prevented; and the damping glue can be prevented from overflowing and breaking when the voice coil motor is running or receiving external impact.
[0033] A welding notch 8 is provided at one end of the base 2 away from the bracket 3, and the welding notch 8 is connected to the fixing hole 7. A power-connecting metal sheet connected to the power-connecting end of the OIS motor is provided on the bottom surface of the welding notch 8, and a lower tin block 9 for fixing the suspension wire 4 is provided in the welding notch 8. The welding notch 8 plays a role of giving way, so that the lower tin block 9 is prevented from protruding from the lower end surface of the base 2 when welding, and the welding notch 8 is filled with the lower tin block 9 to facilitate the fixing of the lower tin block 9.
[0034] Embodiment 3, an OIS motor having the OIS motor anti-damping glue protection structure described in embodiment 1 or embodiment 2, such as Figures 1 to 5 As shown, it also includes a carrier 10 installed in the inner cavity of the bracket 3, an upper spring 11 installed on the carrier 10 and the upper end surface of the bracket 3, and a lower spring 12 installed on the carrier 10 and the lower end surface of the bracket 3. Coils 13 are arranged on the two symmetrical side walls of the carrier 10, and two magnets 14 corresponding to the coils 13 are arranged on the inner wall of the bracket 3.
[0035] The lower end surface of the bracket 3 is provided with a glue storage groove 15 for the glue between the lower spring 12 and the bracket 3 to flow into. The glue storage groove 15 is located at the position of the accommodating groove 5. The glue storage groove 15 can be connected with the avoidance groove 6. The glue storage groove 15 is recessed in the side wall of the bracket 3. Two glue storage grooves 15 can be set on both sides of the accommodating groove 5. The glue storage groove 15 is used to conveniently collect excess glue when the lower spring 12 is fixed to the bracket 3. At the same time, since the damping glue is located in the accommodating groove 5, after the damping glue is thrown out and falls into the glue storage groove 15 or the position of the outer shell 1 corresponding to the glue storage groove 15, the thrown out damping glue contacts the bracket 3 and the outer shell 1 at the same time; that is, when the damping glue falls into the glue storage groove 15, due to the existence of the glue storage groove 15, the damping glue in the glue storage groove 15 is prevented from protruding from the side wall surface of the bracket 3, thereby preventing the damping glue from contacting the inner wall of the outer shell 1 during the shaking or movement of the bracket 3. When the damping glue falls to the position of the outer shell 1 corresponding to the glue storage groove 15, the damping glue is avoided by the glue storage groove 15, so that the damping glue located on the inner wall of the outer shell 1 does not contact the bracket 3, thereby further preventing the damping glue from being thrown out and affecting the normal use of the OIS anti-shake motor.
