Abstract
Description
Technical Field
[0001] The utility model relates to a bolt, and more specifically, to an integrated transmission slider electric bolt. Background Art
[0002] As a key component of the interior decoration of a vehicle, the main function of a car seat is to ensure the stable position of passengers in the vehicle, provide a comfortable riding experience, and protect the safety of passengers when necessary. The seat needs to be installed and fixed with a seat lock, and currently most seats can provide adjustment functions for the driver and passengers, and the angle of the seat can be adjusted within a certain range in an electric manner. However, during the process of adjusting the seat by an electric bolt currently, abnormal noises are likely to occur. The main reason is that the moving components including the slider are composed of multiple splicing parts, resulting in a large gap between the structure of the moving components and the threaded rod in the guiding component during movement. This gap ultimately causes the seat to loosen and collide with abnormal noises during the adjustment process and is difficult to move. Therefore, an integrated transmission slider electric bolt is needed, and this device can avoid the abnormal noises of loosening and collision during the adjustment process of the seat.
[0003] Combined with the above reasons, how to avoid the abnormal noises of loosening and collision during the adjustment process of the seat is exactly the problem considered in this application. Summary of the Utility Model
[0004] In view of the deficiencies of the prior art, an integrated transmission slider electric bolt is provided, and this device can avoid the abnormal noises of loosening and collision during the adjustment process of the seat.
[0005] To achieve the above object, the following technical solutions are provided: The integrated transmission slider electric bolt includes an installation shell, a driving component, a guiding component, a moving component, and a spring piece component. The driving component and the guiding component are both installed in the installation shell. The driving component is used to drive the moving component to move through the guiding component. The moving component is slidably connected to the guiding component. The moving component abuts against the spring piece component, and the spring piece component is slidably abutted against the installation shell.
[0006] The spring piece component includes a connecting seat and a supporting piece. One end of the supporting piece abuts against the installation shell, and the other end of the supporting piece is fixedly connected to the connecting seat. The number of the supporting pieces is at least two.
[0007] One end of the supporting piece facing the installation shell is bent and forms an arc, and the contact surface between the supporting piece and the installation shell is an arc surface.
[0008] In summary, the above technical solution has the following beneficial effects: The driving component, as the power source, can directly drive the guiding component to drive the moving component to move. The moving component is used as the core of the bolt. When the moving component moves, there may be a gap at the connection with the guiding component. Under the action of gravity, it generally faces the installation shell. Therefore, an elastic sheet component is additionally provided for support. While the elastic sheet component plays a supporting role, the moving component is connected to the elastic sheet component, and the elastic sheet component is slidably connected to the installation shell. In this way, the position between the moving component and the installation shell is always fixed. Since the guiding component is installed on the installation shell, gaps can be avoided, thereby preventing rattling noises caused by looseness and collision during the adjustment of the seat.
[0009] One end of the support sheet facing the installation shell forms an arc, which can minimize the contact area to the greatest extent while playing a supporting role. On the one hand, it reduces the wear of the support sheet and eliminates the need for additional processes such as plastic coating. On the other hand, it also reduces the possibility of generating rattling noises.
[0010] In the present utility model, the elastic sheet component provides support between the installation shell and the moving component. The elastic sheet component for support has a certain degree of elasticity, and one end of the support sheet facing the installation shell forms an arc to make the installation shell and the moving component abut and press tightly. At this time, multiple components can be mutually pressed tightly after receiving upward and downward forces respectively, reducing the gaps between the components, and thus reducing the rattling noises caused by looseness.

The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.
[0019] Referring to Figures 1-3 As shown, the integrated drive slider electric bolt includes an installation shell 1, a drive assembly 2, a guiding assembly 3, a moving assembly 4 and a spring piece assembly 5. The drive assembly 2 and the guiding assembly 3 are both installed in the installation shell 1. The drive assembly 2 is used to drive the moving assembly 4 to move through the guiding assembly 3. The moving assembly 4 is slidably connected to the guiding assembly 3. The moving assembly 4 is connected to the spring piece assembly 5. The spring piece assembly 5 is slidably connected to the installation shell 1;
[0020] The moving assembly 4 includes a sliding seat and a bolt 44. The sliding seat is integrally formed by die casting. The sliding seat is an axisymmetric part. The sliding seat includes two side sliding pieces 42 and a slider 41. The guiding assembly 3 includes a threaded rod 31 and a guiding rod 32. Both ends of the moving assembly 4 are fixedly connected to the installation shell 1. The slider 41 is threadedly connected to the threaded rod 31. The guiding rod 32 passes through the sliding pieces 42 on both sides of the sliding seat. The guiding rods 32 are distributed on both sides of the threaded rod 31. The bolt 44 is installed on the slider 41;
[0021] The spring piece assembly 5 includes a connecting seat 51 and a supporting piece 52. One end of the supporting piece 52 is slidably connected to the installation shell 1. The other end of the supporting piece 52 is fixedly connected to the connecting seat 51. The number of the supporting pieces 52 is at least two and they are symmetrically distributed on both sides of the slider 41. The spring piece assembly 5 cooperates with the two side sliding pieces 42 to move along the threaded rod 31. The spring piece assembly 5 abuts between the slider 41 and the installation shell 1;
[0022] One end of the supporting piece 52 facing the installation shell 1 is bent and forms an arc. The contact surface between the supporting piece 52 and the installation shell 1 is an arc surface.
[0023] The driving component 2 serves as a power source and can directly drive the guiding component 3 to drive the moving component 4 to move. The moving component 4 is used as the core of the bolt 44. The sliding seat is integrally formed, which makes it easier to control the relative position of the slider 41 connecting the threaded rod 31 and the guiding rod 32 and the two side sliding pieces 42, avoiding hole position deviation, preventing the moving component 4 from moving slowly or getting stuck during movement, and improving the running stability. When the moving component 4 moves, there may be a gap at the connection with the guiding component 3. Therefore, a spring piece component 5 is provided to support and compensate for the gap. While the spring piece component 5 plays a supporting role, the moving component 4 abuts against the spring piece component 5, and the spring piece component 5 slidably abuts against the mounting shell 1. The supporting piece 52 is an elastic adjusting piece. In this way, when the moving component 4 moves linearly along the guiding component 3, the abutting surface of the supporting piece 52 will deform to varying degrees according to the size of the gap, thereby providing different degrees of elastic force acting in the opposite direction on the mounting shell 1 and the moving component 4, thus avoiding abnormal noises such as loosening and collision during the seat adjustment process;
[0024] One end of the supporting piece 52 facing the mounting shell 1 is formed into an arc shape, which can minimize the contact area to the greatest extent while playing a supporting role. On the one hand, it reduces the wear of the supporting piece 52 and avoids abutting against the sharp edges of the mounting shell 1, eliminating the need for additional processes such as coating with plastic. On the other hand, it also reduces the risk of generating abnormal noises;
[0025] In the present utility model, the spring piece component 5 provides support between the mounting shell 1 and the moving component 4. The spring piece component 5 for support has a certain degree of elastic force, and one end of the supporting piece 52 facing the mounting shell 1 is formed into an arc shape to make the mounting shell 1 and the moving component 4 abut and press tightly. At this time, multiple components can be made to abut tightly against each other after receiving upward and downward forces respectively, compensating for the gaps between the components, and thus reducing abnormal noises caused by loosening.
[0026] Further, the guiding component 3 includes a threaded rod 31 and a guiding rod 32. The moving component 4 includes a slider 41 and sliding pieces 42. The slider 41 is fixedly connected to the sliding pieces 42. The threaded rod 31 is rotatably connected to the mounting shell 1. The guiding rod 32 is fixedly connected to the mounting shell 1. The threaded rod 31 is connected to the driving component 2. The driving component 2 is used to drive the threaded rod 31 to rotate. The slider 41 is threadedly connected to the threaded rod 31. The sliding pieces 42 are slidably connected to the guiding rod 32.
[0027] Further, the moving component 4 further includes a lubricating bushing 43. The lubricating bushing 43 is fixedly connected to the sliding pieces 42. The lubricating bushing 43 is slidably connected to the guiding rod 32.
[0028] Further, the slider 41 and the sliding pieces 42 are integrally formed.
[0029] Further, the moving component 4 further includes a bolt 44, which is fixedly connected to the end of the slider 41 away from the mounting shell 1 and is used to achieve unlocking and locking.
[0030] Further, the elastic piece assembly 5 further includes a contact piece 53, which is fixedly connected to the connecting seat 51. The contact piece 53 is a concave arc structure. The moving component 4 further includes a contact member 45, which is fixedly connected to the slider 41. The contact member 45 is a convex arc structure. The contact member 45 is adapted to the arc surface of the contact piece 53, and the contact member 45 abuts against the contact piece 53.
[0031] Further, the number of the contact pieces 53 is at least two, and the connecting seat 51 and the two contact pieces 53 are both in contact with the contact member 45 in different directions.
[0032] The driving component 2 can adopt an electric driver. The threaded rod 31 is rotatably installed on the mounting bracket, so that the threaded rod 31 can be driven to rotate by meshing the electric driver with the threaded rod 31. The number of the guide rods 32 can be set to multiple, and both ends of each guide rod 32 are fixed on the mounting bracket and pass through the sliding piece 42 in the middle. For the sake of stability, the number of the sliding pieces 42 can also be set to multiple. Under the combined action of the sliding piece 42 cooperating with the guide rod 32 and the slider 41 cooperating with the threaded rod 31, the slider 41 can be driven by the driving component 2 to perform linear reciprocating movement;
[0033] The elastic piece assembly 5 cooperates with the slider 41 to move along the threaded rod 31. The connecting seat 51 serves as the main connecting medium, and the contact member 45 is provided. In this way, the inner end faces of the connecting seat 51 and the two side sliders 41 can be matched, and the contact pieces 53 are all in arc-encircling contact with the contact member 45 to prevent the elastic piece assembly 5 from separating from the moving component 4 from multiple angles and improve the stability of the overall device;
[0034] The slider 41 and the sliding piece 42 are integrally formed by die casting, which avoids the generation of gaps in the structure of the moving component 4 itself. Cooperating with the elastic piece assembly 5 can simplify the process, reduce costs, reduce the structure, improve the accuracy, and improve the stability of the operation of the entire device.
