Description

Technical Field

[0001] This invention relates to the field of mechanical environment testing equipment technology, specifically to a moving coil structure, a mating mechanism, and a long-stroke vibration table. Background Technology

[0002] Electric vibration tables can simulate various vibration dynamic environments and are widely used for simulation tests of various typical vibrations, such as those in automotive parts, electronic components, and aerospace products.

[0003] The prior art discloses a patent application with application number CN105300640A entitled "A Long-Stroke Moving Coil Structure for an Electric Vibration Table". This moving coil structure includes multiple connecting rods, a coil, and upper and lower support frames. During the molding process, the coil needs to be solidified as a whole between the upper and lower support frames first, and then the multiple connecting rods are correspondingly set between the upper and lower support frames. In order to prevent the upper and lower support frames from being squeezed and separated from the coil when the connecting rods are correspondingly set on the upper and lower support frames, the distance between the upper and lower support frames is set to be slightly larger than the length of the connecting rod, so as to ensure that there is a certain gap, which makes it easy for the connecting parts to be inserted between the upper and lower support frames, thereby avoiding applying squeezing force to the upper and lower support frames.

[0004] However, in the above-mentioned moving coil structure, see Figure 10 From a static perspective, the aforementioned gap causes the connecting rod to separate from the upper support frame 001 and the lower support frame 002, thus reducing the overall reliability of the moving coil structure. Furthermore, when the guide rod and connecting rod are fixed in the moving coil structure, the gap 003 may cause the fasteners to be over-tightened, leading to deformation of the upper and lower frames, and even cracks at the solidified connection. From a dynamic perspective, the gap 003 results in lower stiffness of the coil body, and the interval 004 between the coil 005 and the connecting rod 006 lowers the first-order resonant frequency in this direction. After resonance, the coil will deform, affecting test performance. Simultaneously, because the deformed coil will repeatedly contact the connecting rod during testing, it will damage the coil's surface insulation, causing a short circuit and ultimately burning out the coil. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the existing moving coil structure. From a static perspective, the existence of the gap causes the connecting rod to separate from the upper and lower support frames, which leads to a decrease in the overall reliability of the moving coil structure. Furthermore, when the guide rod and connecting rod in the moving coil structure are fixed, the gap may also cause the fasteners to be over-tightened, resulting in deformation of the upper and lower frames and even cracks at the solidified connection. From a dynamic perspective, the existence of the gap leads to low stiffness of the coil body, and the gap between the coil and the connecting rod reduces the first-order resonant frequency in this direction. After resonance, the coil will deform, affecting the test indicators. At the same time, since the coil deformed after resonance will make multiple contacts with the connecting rod during the test, it will damage the insulation of the coil surface, causing a short circuit and ultimately burning out the coil. Therefore, the present invention provides a moving coil structure, a mating mechanism, and a long-stroke vibration table.

[0012] Optionally, in the above-described moving coil structure, the two ends of the winding bobbin extend out of the coil and toward the first support member and the second support member, respectively;

[0013] It also includes a reinforcing member, at least on the portion of the winding bobbin that extends from the coil and toward the second support member, to lock the winding bobbin onto the corresponding second support member.

[0014] Optionally, in the above-described moving coil structure, a reinforcing member is fitted onto the portion of the winding bobbin that extends from the coil and toward the first support member, so as to lock the winding bobbin onto the first support member.

[0015] Optionally, in the above-described moving coil structure, the two connecting portions connected to the same connector are arranged facing each other.

[0016] A small-thrust vibration table includes: a moving coil frame; a moving coil structure, wherein the moving coil structure is as described above, and a lead wire channel is formed on one of the reinforcing members, one end of the lead wire is adapted to extend into the lead wire channel to connect with the winding drum, and the other end is adapted to extend out of the lead wire channel to connect with the moving coil frame.

[0017] Optionally, in the above-mentioned small thrust vibration table, the moving coil skeleton includes a base, and a base hole corresponding to the connecting hole is provided on the base. The locking member is adapted to extend into the base hole and the locking hole in sequence to connect the base and the corresponding support member.

[0018] A long-stroke vibration table includes: a cylinder; a guide structure including a plurality of guide members, one end of any one of the guide members being adapted to extend out of the cylinder; a moving coil structure, the moving coil structure being the moving coil structure as described above, wherein at least one of the guide members is symmetrically arranged on both the first support member and the second support member of the moving coil structure, and in an conductive state, the moving coil structure carries the guide member of the guide structure to reciprocate along the cylinder.

[0019] The technical solution of this invention has the following advantages:

[0020] 1. The present invention provides a moving coil structure, comprising: a first support member and a second support member disposed opposite to each other, wherein at least one connecting portion is provided on the inner wall surface of either support member; at least one connecting member disposed between the first support member and the second support member, wherein any one of the connecting members connects two of the connecting portions disposed on the first support member and the second support member to connect the first support member and the second support member; a coil adapted to be sleeved on the outside of all the connecting members, wherein the two ends of the coil abut against the first support member and the second support member respectively, and there is a gap between the coil and the connecting member, wherein the gap is adapted to be filled with adhesive to connect at least the coil and all the connecting members.

[0021] In this moving coil structure, connecting portions are provided on the inner walls of the first and second supports. Connectors are used to connect these connecting portions on the first and second supports, thus connecting the first and second supports. After connection, the coil is sleeved on the outside of all the connectors, with both ends of the coil abutting against the first and second supports. There is a gap between the coil and the connectors, which is filled with adhesive to connect at least the coil and all the connectors. From a static perspective, this moving coil structure is easy to install, and the direct connection between the first and second supports and the connectors improves connection strength. There is no gap between the ends of the connectors and the first and second supports, preventing the connectors from exerting pressure on them during installation, thus reducing the possibility of separation between the first and second supports and the coil, resulting in high reliability. From a dynamic perspective, the adhesive filling the gap between the coil and the connectors connects the coil and the connectors, allowing the coil to adhere to the first support, second support, and connectors, forming a unified coil structure with high strength and reliability. This design provides excellent assurance, ensuring that the coil will not deform significantly during vibration. This prevents repeated contact with the connecting rod, which could damage the coil's surface insulation and cause short circuits. Furthermore, by embedding the connector within the coil, the support and connector can be assembled before winding, ensuring a tight connection between the three. This overcomes the shortcomings of existing moving-coil structures. From a static perspective, the aforementioned gaps can cause the connecting rod to separate from the upper and lower support frames, leading to a decrease in the overall reliability of the moving-coil structure. Additionally, gaps in the guide rod and connecting rod fixing in the aforementioned moving-coil structure could lead to over-tightening of fasteners, causing deformation of the upper and lower frames and even cracks at the solidified connection. From a dynamic perspective, the aforementioned gaps result in lower coil body stiffness, and the gap between the coil and connecting rod reduces the first-order resonant frequency in this direction. After resonance, the coil will deform, affecting test performance. Furthermore, the deformed coil will repeatedly contact the connecting rod during testing, causing damage to the coil's surface insulation, resulting in short circuits and ultimately coil burnout.

[0022] 2. In the moving coil structure provided by the present invention, a connecting hole is formed on the connecting part along the axial direction of the connector, and one end of the connector is adapted to extend into the connecting hole to connect with the connecting part.

[0023] In the moving coil structure of this design, the connection hole allows the connector to connect with the connecting part, thereby connecting the connector, the first support, and the second support, which facilitates the installation and positioning of the support and the connector.

[0024] 3. The moving coil structure provided by the present invention further includes a locking member, with locking holes provided at both ends of the connector. The locking member is provided in a one-to-one correspondence with the locking hole, and the locking member is adapted to be inserted into the locking hole to apply a locking force to the connector. Under the action of the locking force, the outer wall surface of the connector fits against the inner wall surface of the connecting hole.

[0025] In the moving coil structure of this design, a locking element is provided, which corresponds to the locking holes at both ends of the connecting element. The locking element is adapted to be inserted into the locking hole to connect the connecting element, the first support element, and the second support element, thereby further improving the connection stability of the moving coil structure.

[0026] 4. In the moving coil structure provided by the present invention, the two ends of the winding drum extend out of the coil and extend toward the first support member and the second support member, respectively; it also includes a reinforcing member, at least on the portion of the winding drum that extends out of the coil and toward the second support member, the reinforcing member is sleeved to lock the winding drum onto the second support member.

[0027] In this moving coil structure, a reinforcing member is used to lock the winding drum onto the second support member, preventing displacement of the winding drum relative to the second support member. This ensures the installation stability of the winding drum and the second support member and further improves the reliability of the moving coil structure.

[0028] 5. In the moving coil structure provided by the present invention, a reinforcing member is fitted on the portion of the winding bobbin that extends out of the coil and toward the first support member, so as to lock the winding bobbin onto the first support member.

[0029] In this moving coil structure, a reinforcing member is fitted onto the portion of the winding drum that extends from the coil and towards the first support member to lock the winding drum onto the first support member. This achieves the goal of providing a reinforcing member at both ends of the winding drum and a reinforcing member on both the first and second support members, which can further improve the connection strength between the winding drum and the first and second support members, thereby ensuring the reliability of the moving coil structure.

[0052] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] Example 1

[0054] This embodiment describes a moving coil structure, which participates in... Figures 1-9 The moving coil structure includes: a first support member 1 and a second support member 2 arranged opposite to each other, at least one connecting part 3 provided on the inner wall surface of either support member, and a connecting member 4 and a coil 5. The connecting member 4 is disposed between the first support member 1 and the second support member 2, and the two connecting parts 3 respectively disposed on the first support member 1 and the second support member 2 are connected by the connecting member 4 to connect the first support member 1 and the second support member 2. After the assembly between the connecting member 4, the first support member 1 and the second support member 2 is completed, the coil 5 is adapted to be sleeved on the outside of all the connecting members 4, and the two ends of the coil 5 respectively abut against the first support member 1 and the second support member 2. There is a gap 6 between the coil 5 and the connecting member 4, and the gap 6 is adapted to be filled with adhesive to connect at least the coil 5 and all the connecting members 4.

[0055] By providing connecting portions 3 on the inner walls of the first support member 1 and the second support member 2, and using connecting members 4 to connect the connecting portions 3 respectively on the first support member 1 and the second support member 2, the first support member 1 and the second support member 2 are connected. After the connection is completed, the coil 5 is sleeved on the outside of all the connecting members 4, and the two ends of the coil 5 abut against the first support member 1 and the second support member 2, with a gap 6 between the coil 5 and the connecting members 4. The gap 6 is filled with adhesive to connect at least the coil 5 and all the connecting members 4. From a static point of view, this moving coil structure is easy to install, and the direct connection between the first support member 1 and the second support member 2 and the connecting members 4 improves the connection strength. There is no gap between the end of the connecting member 4 and the first support member 1 and the second support member 2. During the installation process, the connecting member 4 will not leak into the first support member 1 and the second support member 2. The two support members 2 apply compressive force, thereby reducing the possibility of separation between the first support member 1 and the second support member 2 and the coil 5, resulting in high reliability. From a dynamic perspective, adhesive is filled in the gap 6 between the coil 5 and the connector 4, and the coil 5 and the connector 4 are connected by the adhesive. This allows the coil 5 to adhere to the first support member 1, the second support member 2, and the connector 4, forming an integral coil 5 structure. This improves the torsional resistance of the coil 5, and its strength and reliability are well guaranteed. It ensures that the coil 5 will not undergo large deformation during vibration, thus preventing multiple contacts with the connecting rod that could damage the surface insulation of the coil 5 and cause a short circuit. Furthermore, by embedding the connector 4 inside the coil 5, the support member and the connector 4 can be assembled before winding, ensuring a tight connection between the three.

[0056] In practical applications, the number of the aforementioned connectors 4 can be one or more, primarily for connecting the first support member 1 and the second support member 2. The number of connecting parts 3 provided on the support members can also be one or more, depending on whether the connectors 4 can connect the first support member 1 and the second support member 2. (See [reference]). Figure 2 In this embodiment, the number of connectors 4 is set to four, and correspondingly, the number of connecting parts 3 is also set to four. Of course, the number of connectors 4 can also be set to five or six. The specific number is set according to the actual use. The connectors 4 can be set to a cylindrical rod structure.

[0057] See Figure 9In order to install and position the connector 4 and the first support 1 and the second support 2, a connecting hole 301 can be opened on any connecting part 3 along the axial direction of any of the connectors 4. The two ends of the connector 4 are adapted to be inserted into the corresponding connecting hole 301 to complete the connection with the connecting part 3, thereby realizing the connection of the first support 1 and the second support 2 using the connecting hole 301. The setting of the connecting hole 301 enables the connector 4 to be connected with the connecting part 3, thereby realizing the connection of the connector 4, the first support 1 and the second support 2, which facilitates the installation and positioning of the support and the connector 4.

[0058] To further improve the connection stability of the moving coil structure, see [link / reference]. Figure 2 and Figure 8 In this embodiment, the moving coil structure also includes a locking member 7. Locking holes 401 are opened at both ends of the connecting member 4. The locking member 7 is provided in a one-to-one correspondence with the locking holes 401, and the locking member 7 is adapted to be inserted into the locking holes 401 to apply a locking force to the connecting member 4. Under the action of the locking force, the outer wall surface of the connecting member 4 is in contact with the inner wall surface of the connecting hole 301. By providing the locking member 7, the locking member 7 is provided in a corresponding manner with the locking holes 401 at both ends of the connecting member 4, and the locking member 7 is adapted to be inserted into the locking holes 401 to connect the connecting member 4, the first support member 1 and the second support member 2, thereby further improving the connection stability of the moving coil structure.

[0059] In practical applications, the locking element 7 can be set as a bolt, with a threaded surface on the inner wall of the locking hole 401, so that the locking element 7 and the corresponding connecting element 4 are threadedly connected, and the end of the locking element 7 is blocked by the support, thus completing the fixation of the end of the connecting element 4 to the support. Of course, the locking element 7 can also be set as a pin, and the connecting element 4 and the support are connected by a pin, so as to achieve the connection and fixation of the connecting element 4 and the support.

[0060] See Figure 9 In the moving coil structure of this embodiment, the connecting part 3 is a boss formed on the inner wall of the corresponding support member. The two ends of all the bosses on the same support member are aligned. Aligning the two ends of all the bosses on the same support member ensures that after the connecting member 4 is connected to the first support member 1 and the second support member 2, the height of all the connecting members 4 is consistent. After assembly, the coaxiality of the outer diameter of the entire moving coil structure can be well guaranteed. It should be noted that aligning the two ends of the bosses on the same support member means that at any angle, the two ends of all the bosses are in the same plane. This ensures that after the connecting member 4 is inserted into the connecting hole 301 in the boss, the length of the connecting member 4 not inserted into the connecting hole 301 is consistent, which facilitates the installation of the coil 5.

[0061] In this embodiment, the projection of any of the connecting members 4 in the axial direction of the moving coil structure falls into the projection of any of the supporting members in the axial direction of the moving coil structure. More preferably, both projections are orthographic projections.

[0062] See Figure 3 The moving coil structure in this embodiment also includes a winding drum 8. The coil 5 has a composite layer structure, which includes at least two coil layers 5. A winding drum 8 is provided between two adjacent coil layers 5. The winding drum 8 can realize the separation between the coil layers 5 when the coil 5 is set as a composite layer structure.

[0063] See Figure 3 and Figure 4 To further improve the stability of the moving coil structure, the two ends of the winding drum 8 can extend out of the coil 5 and towards the first support member 1 and the second support member 2, respectively. A reinforcing member 9 can be fitted onto the part of the winding drum 8 that extends out of the coil 5 and towards the second support member 2 to lock the winding drum 8 onto the second support member 2. Alternatively, a reinforcing member 9 can be fitted onto the part of the winding drum 8 that extends out of the coil 5 and towards the first support member 1 to lock the winding drum 8 onto the first support member 1.

[0064] In practical applications, the reinforcing member 9 can be set as a ring-shaped reinforcing ring. Adhesive can be filled between the reinforcing ring, the winding drum 8, and the support member to improve the connection stability between the three.

[0065] To ensure that the two ends of the connector 4 are aligned when connecting the first support 1 and the second support 2, the two connecting parts 3 connecting the same connector 4 can be aligned face-to-face, and all connecting parts 3 can be evenly distributed on the inner wall surface of the corresponding support. For example, see... Figure 2 When the number of connecting parts 3 is set to four, the two adjacent connecting parts 3 are set at a 90-degree angle; when the number is set to three, the two adjacent connecting parts 3 are set at a 120-degree angle.

[0066] In this embodiment, the first support member 1 and the second support member 2 are configured as a ring structure. In order to improve the positioning convenience between the reinforcing member 9 and the corresponding support member, a stepped surface can be opened on the first support member 1 and the second support member 2. The stepped surface is adapted to the reinforcing member 9. When the coil 5 is in the form of a multi-layer coil 5, the outermost coil 5 layer abuts against the reinforcing member 9, and the end of the outermost coil 5 layer abuts against the end face of the reinforcing member 9.

[0067] Example 2:

[0068] This embodiment describes a low-thrust vibration table. See [link to documentation]. Figure 5The small-thrust vibration table includes a moving coil frame 10 and a moving coil structure. The moving coil structure is the moving coil structure described in Embodiment 1. A lead wire channel is opened on one of the reinforcing members 9. One end of the lead wire is adapted to extend into the lead wire channel to connect with the winding drum 8, and the other end is adapted to extend out of the lead wire channel to connect with the moving coil frame 10. Since the small-thrust vibration table adopts the moving coil structure described in Embodiment 1, it has the beneficial effects of the moving coil structure.

[0069] See Figure 5 A lead wire channel can be opened on the reinforcing member 9 located on the second support member 2.

[0070] In this embodiment of the small-thrust vibration table, the moving coil frame 10 includes a base 1001. The base 1001 has a base hole corresponding to the connecting hole 301. The locking member 7 is adapted to extend sequentially into the base hole and the locking hole 401 to connect the base 1001 and the corresponding support member. This moving coil structure can be quickly disassembled from the base 1001. If the moving coil structure is damaged due to prolonged use, it can be quickly replaced, making it convenient to use and serving as a spare part, significantly shortening repair time. In specific applications, the base 1001 can be mounted on the second support member 2.

[0071] Example 3:

[0072] This embodiment describes a long-stroke vibration table. See [link to documentation]. Figure 6 The long-stroke vibration table includes a cylinder (not shown in the figure), a guide structure, and a moving coil structure. The guide structure includes several guide members 11, one end of which is adapted to extend out of the cylinder. The moving coil structure is the moving coil structure described in Embodiment 1. The moving coil structure is located inside the cylinder. At least one guide member 11 is symmetrically arranged on the first support member 1 and the second support member 2 of the moving coil structure. In an conductive state, the moving coil structure carries the guide members 11 of the guide structure to reciprocate along the cylinder.

[0073] In practical applications, the end of any of the above-mentioned guide members 11 can be threadedly fixed to the support member. This long-stroke vibration table has high strength and high reliability, and the performance of the special moving coil is greatly improved.

[0074] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
