Description

Technical Field

[0001] This application relates to the field of camera technology, specifically to a buffer for a camera module, a camera module, and a terminal device. Background Technology

[0002] In recent years, with the increasing imaging demands of smart terminal devices, zoom camera modules have become standard components. Currently, zoom camera modules typically use a voice coil motor (VCM) to drive the lens unit along the optical axis to achieve optical zoom. However, with the increasing demand for high-magnification zoom, the stroke and size of the voice coil motor have increased accordingly, leading to a significant increase in the inertial momentum of the lens mount during the driving process. During rapid zooming, the lens mount is prone to rigid impact with the module housing, generating abnormal acoustic noise, which seriously affects the user experience. This problem is particularly prominent in thin and light devices such as smartphones due to structural space constraints. Therefore, there is an urgent need to develop a lens mount buffer structure to effectively suppress mechanical impact noise during zooming. Utility Model Content

[0003] In view of the above, it is necessary to provide a buffer for a camera module, a camera module, and a terminal device to reduce abnormal noise when the lens mount impacts the module housing.

[0004] In a first aspect, embodiments of this application provide a buffer for a camera module, comprising: a connecting portion having a connecting surface; and at least one buffer portion, one end of the buffer portion being connected to the connecting surface, the other end of the buffer portion extending away from the connecting surface, the end face of the other end of the buffer portion being located on a virtual surface, the virtual surface being parallel to the connecting surface, wherein, in a direction perpendicular to the connecting surface, a first distance of any cross-section of the buffer portion is less than a second distance, the first distance being the distance between the end of the cross-section closest to the connecting surface and the end closest to the virtual surface, and the second distance being the distance between the connecting surface and the virtual surface.

[0005] When the aforementioned buffer is applied to a camera module, the connecting part of the buffer is connected to the lens mount, and the buffer part of the buffer faces the module housing. The driving component of the camera module drives the lens mount to move. When the other end of the buffer part impacts the module housing, since the first distance of any cross-section of the buffer part is less than the second distance, that is, the buffer part is not solid from the connecting surface to the virtual surface, there is a buffer gap between the connecting surface and the virtual surface. This allows the buffer gap to play a buffering role when the buffer part is impacted. Specifically, firstly, the buffer part itself can play a supporting role, preventing the lens mount from being impacted. The direct impact between the mount and the module housing significantly reduces impact noise. Secondly, since the buffer part has a buffer gap between the connecting surface and the virtual surface, it is compressed and bends towards the connecting part when subjected to the reaction force of the module housing. The buffer part generates a rebound force, which buffers the impact between the lens mount and the module housing, effectively reducing abnormal noise. Thirdly, since the buffer part has a buffer gap between the connecting surface and the virtual surface, the buffer gap can increase the compression stroke of the buffer part, while avoiding reducing the movement stroke of the lens mount, ensuring the high magnification zoom requirements of the camera module.

[0006] In one embodiment, the buffer is configured as a linear structure, and the buffer is inclined relative to the connecting surface.

[0007] The aforementioned buffer, by configuring the buffer part as a linear structure and limiting the buffer part to be inclined relative to the connecting surface, is beneficial to ensure that the buffer part has a buffer gap from the connecting surface to the virtual surface; at the same time, it is easy to process the buffer part.

[0008] In one embodiment, the buffer portion is configured as at least two, the at least two buffer portions being spaced apart, wherein the tilt direction of one buffer portion is opposite to the tilt direction of the other buffer portion.

[0009] The aforementioned buffer, by configuring at least two buffer sections and limiting the tilt direction of one buffer section to be opposite to that of the other buffer section, makes the tilt directions of the buffer sections not completely the same, significantly improving the buffering effect of the buffer and enabling the camera module to achieve a silent effect.

[0010] In one embodiment, the included angle between the buffer portion and the connecting surface ranges from 30° to 50°.

[0011] The aforementioned buffer, by limiting the angle range between the buffer part and the connecting surface, ensures that the buffer part can provide effective support and cushioning without affecting the movement of the lens mount.

[0012] In one embodiment, the buffer further includes a support portion, one end of which is connected to the other end of the buffer portion, the other end of which extends toward a side inclined towards the buffer portion, and the surface of the support portion facing away from the connecting surface is located on the virtual surface.

[0013] The aforementioned buffer, by setting the aforementioned support portion, increases the impact area between the buffer and the module housing, thereby effectively reducing abnormal noise during impact. The support portion also has a buffer gap between the connecting surface and the virtual surface.

[0014] In one embodiment, the support is configured as a linear structure, a cylindrical segment structure, or a spherical cap structure.

[0015] The aforementioned buffer increases the impact area between the buffer and the module housing by configuring the support part as a linear structure; and enhances the buffering force of the buffer on the module housing by configuring the support part as a cylindrical segment structure or a spherical crown structure.

[0016] In one embodiment, the buffer is configured as a beveled rounded corner structure or a beveled chamfered surface structure.

[0017] The aforementioned buffer component, by configuring the buffer part as a beveled arc corner structure or a beveled chamfered surface structure, ensures that the buffer part has a buffer gap between the connecting surface and the virtual surface; at the same time, it facilitates the processing of the buffer component.

[0018] In one embodiment, the buffer section has a buffer hole.

[0019] The aforementioned buffer component increases the buffer gap of the buffer section by opening buffer holes in the buffer section, thereby increasing the buffering effect of the buffer section and achieving a silent effect.

[0020] Secondly, embodiments of this application also provide a camera module, including a module housing, a lens mount, a lens unit, a driving member, and a buffer as described in any of the above technical solutions. The lens mount is movably disposed on the module housing, the lens unit is disposed on the lens mount, the driving member is disposed between the lens mount and the module housing, the driving member drives the lens mount to move within the module housing, and the buffer is configured to be disposed on both sides of the lens mount along the moving direction of the lens mount.

[0021] In the aforementioned camera module, the connecting part of the buffer component is connected to the lens mount, with the buffer part facing the module housing. The driving component drives the lens mount to move. When the other end of the buffer part impacts the module housing, because the first distance of any cross-section of the buffer part is less than the second distance, i.e., the buffer part is not solid from the connecting surface to the virtual surface, there is a buffer gap between the connecting surface and the virtual surface. This allows the buffer part to play a buffering role when impacted. Specifically, firstly, the buffer part itself can provide support, preventing the lens mount from colliding with the module housing. Direct impact significantly reduces impact noise. Secondly, since the buffer part has a buffer gap between the connecting surface and the virtual surface, it is compressed and bends towards the connecting part when subjected to the reaction force of the module housing. The buffer part generates a rebound force, which buffers the impact between the lens mount and the module housing, effectively reducing abnormal noise. Thirdly, since the buffer part has a buffer gap between the connecting surface and the virtual surface, the buffer gap can increase the compression stroke of the buffer part, while avoiding reducing the movement stroke of the lens mount, ensuring the high magnification zoom requirements of the camera module.

[0022] Thirdly, embodiments of this application also provide a terminal device, including the camera module described in the above technical solution.

[0023] In the aforementioned terminal device, the connecting part of the buffer component in the camera module is connected to the lens mount. The buffer part of the buffer component faces the module housing. The driving component drives the lens mount to move. When the other end of the buffer part impacts the module housing, since the first distance of any cross-section of the buffer part is less than the second distance, that is, the buffer part is not solid from the connecting surface to the virtual surface, there is a buffer gap between the connecting surface and the virtual surface. This allows the buffer part to play a buffering role when it is impacted. Specifically, firstly, the buffer part itself can play a supporting role, preventing the lens mount from colliding with the module. Direct impact to the housing significantly reduces impact noise. Secondly, because the buffer part has a buffer gap between the connecting surface and the virtual surface, it is compressed and bends towards the connecting part when subjected to the reaction force of the module housing. The buffer part generates a rebound force, which buffers the impact between the lens mount and the module housing, effectively reducing abnormal noise. Thirdly, because the buffer part has a buffer gap between the connecting surface and the virtual surface, the buffer gap can increase the compression stroke of the buffer part, while avoiding reducing the movement stroke of the lens mount, ensuring the high magnification zoom requirements of the terminal device.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0039] Please see Figure 1 The first embodiment of this application provides a camera module 1 (see [link to application]). Figure 10 The buffer 10 is used to buffer the lens mount 200 of the camera module 1 (see [link]). Figure 10 ) and the module housing 100 of camera module 1 (see Figure 10 The impact between the lens mount 200 and the module housing 100 is reduced to minimize abnormal noise when the lens mount 200 impacts the module housing 100.

[0040] The buffer 10 includes a connecting portion 12 and at least one buffer portion 14. In this embodiment, the connecting portion 12 is used to connect with the lens mount 200. The connecting portion 12 has a connecting surface 121. One end of the buffer portion 14 is connected to the connecting surface 121, and the other end of the buffer portion 14 extends away from the connecting surface 121. The end face 141 of the other end of the buffer portion 14 is located on a virtual surface 151, which is parallel to the connecting surface 121. Specifically, in a direction perpendicular to the connecting surface 121, the first distance 152 of any cross section 143 of the buffer portion 14 is smaller than the second distance 153. The cross section 143 is perpendicular to the connecting surface 121. The first distance 152 is the distance between the end of the cross section 143 closest to the connecting surface 121 and the end closest to the virtual surface 151. The second distance 153 is the distance between the connecting surface 121 and the virtual surface 151. By defining that the first distance 152 of any cross section 143 of the buffer portion 14 is less than the second distance 153, that is, the buffer portion 14 is not solid from the connecting surface 121 to the virtual surface 151, so that the buffer portion 14 has a buffer gap 16 from the connecting surface 121 to the virtual surface 151. When the other end of the buffer portion 14 is subjected to a force, the buffer portion 14 is compressed and bends toward the connecting portion 12. The buffer portion 14 generates a rebound force due to bending, and at the same time the buffer gap 16 will decrease to provide a buffer stroke for the lens mount 200.

[0041] Understandably, the connecting part 12 can be a linear structure or an arc-shaped structure, and one, two, or more buffers 10 can be provided on the periphery of one side of the lens carrier 200; the connecting part 12 can also be a circular structure, and one buffer 10 can be provided on the periphery of one side of the lens carrier 200. This application embodiment does not specifically limit this, and the specific design can be made according to the actual situation. Understandably, a linear structure here can be understood as the connecting part 12 extending approximately in a straight line, and an arc-shaped structure can be understood as the connecting part 12 having an arc, and multiple arc-shaped connecting parts 12 can approximately form a circular structure.

[0042] In this embodiment, the connecting part 12 and the buffer part 14 can be integrally formed, and both the connecting part 12 and the buffer part 14 are made of silicone.

[0043] In this embodiment, the buffer portion 14 is configured as a linear structure, and the buffer portion 14 is inclined relative to the connecting surface 121. Specifically, the buffer portion 14 is approximately a parallelogram structure, with one corner being chamfered. Thus, by configuring the buffer portion 14 as a linear structure and limiting its inclined arrangement relative to the connecting surface 121, it is advantageous to ensure that the buffer portion 14 has a buffer gap 16 between the connecting surface 121 and the virtual surface 151; it also facilitates the processing of the buffer member 10. It can be understood that the linear structure here means that the buffer portion 14 extends approximately along a straight line.

[0044] In this embodiment, at least two buffer portions 14 are configured, spaced apart on the connecting surface 121. The inclination direction of one buffer portion 14 is opposite to that of the other buffer portion 14; that is, the inclination directions of the buffer portions 14 are not entirely the same. Specifically, in this embodiment, there are four buffer portions 14. Two adjacent buffer portions 14 have the same inclination direction, another two adjacent buffer portions 14 have the same inclination direction, and the inclination directions of the other two adjacent buffer portions 14 are opposite to those of the two adjacent buffer portions 14. Understandably, in other embodiments, three buffer portions 14 may have the same inclination direction, and the inclination direction of another buffer portion 14 may be opposite to the inclination directions of the other three buffer portions 14.

[0045] In this embodiment, the included angle α between each buffer portion 14 and the connecting surface 121 ranges from 30° to 50°. Preferably, the included angle α between each buffer portion 14 and the connecting surface 121 ranges from 40°. It can be understood that the included angle α between each buffer portion 14 and the connecting surface 121 can also be 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, etc. Thus, by limiting the included angle α between the buffer portion 14 and the connecting surface 121 to a range of 30° to 50°, it is ensured that the buffer portion 14 can provide effective support and cushioning without affecting the movement stroke of the lens mount 200. However, when the included angle α between the buffer part 14 and the connecting surface 121 is less than 30°, the buffer gap 16 between the buffer part 14 and the connecting surface 121 is too small, and the buffer member 10 will affect the movement stroke of the lens mount 200, which is not conducive to the high magnification zoom requirement of the camera module 1. When the included angle α between the buffer part 14 and the connecting surface 121 is greater than 50°, the buffer part 14 is not easy to be compressed and bend towards the connecting part 12, and the buffering effect of the buffer member 10 is poor, which is not conducive to reducing abnormal noise.

[0046] Understandably, when at least two buffer portions 14 have the same tilt direction, the range of the included angle between each of them and the connecting portion 12 may not be exactly the same.

[0047] When the buffer 10 of this embodiment is applied in the camera module 1, the connecting part 12 of the buffer 10 is connected to the lens carrier 200, and the four buffer parts 14 of the buffer 10 face the module housing 100. The driving member 400 of the camera module 1 (see [link to documentation]) Figure 10When the lens mount 200 moves and simultaneously impacts the module housing 100 at the other ends of the four buffer sections 14, the first distance 152 of any cross section 143 of the buffer section 14 is smaller than the second distance 153. This means the buffer section 14 is not solid between the connecting surface 121 and the virtual surface 151, resulting in a buffer gap 16 between the connecting surface 121 and the virtual surface 151. This buffer gap 16 allows the buffer section 14 to buffer when impacted. Specifically, firstly, the four buffer sections 14 cooperate to provide support, preventing direct impact between the lens mount 200 and the module housing 100, significantly reducing impact noise. Secondly... In terms of the buffer section 14, since there are buffer gaps 16 between the connecting surface 121 and the virtual surface 151, the other ends of the four buffer sections 14 are compressed and bent toward the connecting section 12 when subjected to the reaction force of the module housing 100. The four buffer sections 14 generate a rebound force, which buffers the impact between the lens carrier 200 and the module housing 100 through the rebound force of the four buffer sections 14, effectively reducing abnormal noise. In terms of the third direction, since there are buffer gaps 16 between the connecting surface 121 and the virtual surface 151, the buffer gaps 16 can increase the compression stroke of the buffer section 14, while avoiding reducing the movement stroke of the lens carrier 200, ensuring the high magnification zoom requirements of the camera module 1.

[0048] Please see Figure 2 The second embodiment of this application provides a buffer 20 for a camera module 1. The buffer 20 provided in this embodiment is generally similar in structure to the buffer 10 provided in the first embodiment, except that: in this embodiment, there are two buffer parts 14, and the two buffer parts 14 are tilted in opposite directions.

[0049] Please see Figure 3 The third embodiment of this application provides a buffer 30 for a camera module 1. The buffer 30 provided in this embodiment is generally similar in structure to the buffer 10 provided in the first embodiment, except that: in this embodiment, there are three buffer parts 14, two of which have the same tilt direction, and the other buffer part 14 has the opposite tilt direction to the two buffer parts 14.

[0050] Please see Figure 4This application provides a fourth embodiment of a buffer 40 for a camera module 1. The buffer 40 provided in this embodiment is structurally similar to the buffer 10 provided in the first embodiment, except that in this embodiment, there are four buffer portions 14. Arranged from top to bottom, the first and third buffer portions 14 have the same inclination direction, while the second and fourth buffer portions 14 have the same inclination direction but opposite to the inclination directions of the other two buffer portions 14. Each of the four buffer portions 14 has a buffer hole 142, which can be a circular hole. In the direction perpendicular to the connecting surface 121, the third distance 154 of any cross-section 143 of the buffer portion 14 is less than the second distance 153. The third distance 154 is the first distance 152 of the cross-section 143 minus the distance of the buffer hole 142 in the corresponding direction. Thus, by further opening buffer holes 142 on the buffer portions 14, the buffer gap 16 of the buffer portions 14 is increased, thereby increasing the buffering effect of the buffer portions 14 and achieving a silent effect. When the buffer part 14 impacts the module housing 100, as the buffer part 14 is compressed and bent, the buffer hole 142 is also compressed, further increasing the rebound force of the buffer part 14, thereby increasing the buffering effect of the buffer part 14 to achieve a silent effect.

[0051] Understandably, in other embodiments, the shape of the buffer hole 142 can also be an elliptical hole, a strip hole, a polygonal hole, an irregular hole, etc. This application embodiment does not specifically limit this, and it can be set according to the actual situation.

[0052] Please see Figure 5 This application provides a buffer 50 for a camera module 1 in its fifth embodiment. The buffer 50 provided in this embodiment is structurally similar to the buffer 10 provided in the first embodiment, except that the number of buffer portions 14 is one. Furthermore, the buffer 50 also includes a support portion 18. One end of the support portion 18 is connected to the other end of the buffer portion 14, and the other end of the support portion 18 extends towards the side inclined towards the buffer portion 14. The surface of the support portion 18 facing away from the connecting portion 12 is also located on the virtual surface 151. A buffer gap 16 is also provided between the support portion 18 and the virtual surface 151. Thus, by providing the aforementioned support portion 18, the impact area between the buffer 50 and the module housing 100 is increased, thereby effectively reducing abnormal noise during impact.

[0053] In this embodiment, the support portion 18 is configured as a linear structure. By configuring the support portion 18 as a linear structure, the impact area between the buffer 50 and the module housing 100 is increased. It can be understood that the linear structure here means that the support portion 18 extends approximately in a straight line.

[0054] Understandably, in other embodiments, the number of buffer portions 14 and support portions 18 may be two, three or more, and the support portions 18 do not interfere with each other. This application embodiment does not specifically limit this, and the specific number can be set according to the actual situation.

[0055] Please see Figure 6 The sixth embodiment of this application provides a buffer 60 for a camera module 1. The buffer 60 provided in this embodiment is structurally similar to the buffer 10 provided in the first embodiment, except that in this embodiment, the buffer 60 further includes four support portions 18, each corresponding to one of the four buffer portions 14. One end of each support portion 18 is connected to the other end of the corresponding buffer portion 14, and the other end of each support portion 18 extends towards the side inclined towards the buffer portion 14. The surface of each support portion 18 facing away from the connecting portion 12 is located on a virtual surface 151. Each support portion 18 also has a buffer gap 16 between the connecting surface 121 and the virtual surface 151. In this embodiment, each buffer portion 14 is configured as a spherical crown structure. By configuring the support portion 18 as a spherical crown structure, the weight and area of ​​the other end of the buffer portion 14 are increased, which helps to increase the rebound force generated when the buffer portion 14 bends, thereby improving the buffering force of the buffer 60 on the module housing 100. Understandably, the spherical cap structure here can be understood as the part containing the center of a sphere obtained by cutting a sphere with a plane.

[0056] Understandably, in other embodiments, the support portion 18 may also be configured as a cylindrical segment structure, and this application embodiment does not specifically limit this. Understandably, the cylindrical segment structure here can be understood as a portion including the central axis of a cylinder obtained by cutting a cylinder with a plane.

[0057] Please see Figure 7 The seventh embodiment of this application provides a buffer 70 for a camera module 1. The buffer 70 provided in this embodiment is structurally similar to the buffer 10 provided in the first embodiment, except that in this embodiment, all four buffer portions 14 are configured with a beveled rounded corner structure, and the end face 141 of the other end of each buffer portion 14 is also located on the virtual surface 151. By configuring the buffer portions 14 with a beveled rounded corner structure, the bending resistance and deformation resistance of the buffer portions 14 are improved, and the buffer portions 14 have strong resilience, which helps ensure the stable use of the buffer 70. It can be understood that the beveled rounded corner structure here can be understood as a structure formed by arcs, rounded arcs, and straight lines.

[0058] Please see Figure 8This application provides an eighth embodiment of a buffer 80 for a camera module 1. The buffer 80 provided in this embodiment is structurally similar to the buffer 10 provided in the first embodiment, except that in this embodiment, all four buffer portions 14 are configured with a chamfered surface structure, and the end face 141 of the other end of each buffer portion 14 is also located on the virtual surface 151. This can be understood as the end face 141 of the other end of each buffer portion 14 being tangent to the virtual surface 151. By configuring the buffer portions 14 with a chamfered surface structure, the bending resistance and deformation resistance of the buffer portions 14 are improved, and the buffer portions 14 have strong resilience, which helps ensure the stable use of the buffer 80. It can be understood that the chamfered surface structure here can be understood as a structure formed by irregular arcs, similar to a "bent cone" structure.

[0059] Please see Figure 9 The ninth embodiment of this application provides a buffer 90 for a camera module 1. The buffer 90 provided in this embodiment is structurally similar to the buffer 10 provided in the first embodiment, except that in this embodiment, the number of buffer portions 14 is one.

[0060] Please see Figure 10 This application's tenth embodiment provides a camera module 1. The camera module 1 includes a module housing 100, a lens mount 200, a lens unit 300, a drive member 400, and a buffer member as described in any of the previous embodiments. This embodiment uses the buffer member 10 provided in the first embodiment as an example. The lens mount 200 is movably disposed within the module housing 100, the lens unit 300 is disposed within the lens mount 200, and the drive member 400 is disposed between the lens mount 200 and the module housing 100. The drive member 400 drives the lens mount 200 to move within the module housing 100, thereby enabling the camera module 1 to zoom. The buffer member 10 is configured to be disposed on both sides of the lens mount 200 along the moving direction of the lens mount 200. The drive member 400 and the lens mount 200 can generally constitute a voice coil motor structure, which will not be elaborated further in this embodiment. Specifically, in this embodiment, the camera module 1 is a periscope camera module. The camera module 1 also includes a photosensitive chip 500 and a prism unit 600. The photosensitive chip 500 is disposed within the module housing 100 and located on the image side of the lens mount 200. The prism unit 600 is disposed within the module housing 100 and located on the object side of the lens mount 200. The photosensitive chip 500 is used to receive light signals passing through the prism unit 600 and the lens unit 300 and convert them into electrical signals for imaging.

[0061] In the camera module 1 provided in this embodiment, the connecting part 12 of the buffer 10 is connected to the lens carrier 200, and the buffer part 14 of the buffer 10 faces the module housing 100. The driving member 400 drives the lens carrier 200 to move. When the other end of the buffer part 14 impacts the module housing 100, since the first distance 152 of any cross section 143 of the buffer part 14 is smaller than the second distance 153, that is, the buffer part 14 is not solid from the connecting surface 121 to the virtual surface 151, so that the buffer part 14 has a buffer gap 16 from the connecting surface 121 to the virtual surface 151. Thus, the buffer gap 16 of the buffer part 14 can play a buffering role when it is impacted. Specifically, in the first aspect, the buffer part 14 plays a supporting role and avoids the lens carrier 200 from impacting the module housing 100. The direct impact between the lens mount 200 and the module housing 100 significantly reduces impact noise. Secondly, since the buffer part 14 has a buffer gap 16 between the connecting surface 121 and the virtual surface 151, the other end of the buffer part 14 is compressed and bent towards the connecting part 12 when subjected to the reaction force of the module housing 100. The buffer part 14 generates a rebound force, which buffers the impact between the lens mount 200 and the module housing 100, effectively reducing abnormal noise. Thirdly, since the buffer part 14 has a buffer gap 16 between the connecting surface 121 and the virtual surface 151, the buffer gap 16 can increase the compression stroke of the buffer part 14, while avoiding reducing the movement stroke of the lens mount 200, ensuring the high magnification zoom requirements of the camera module 1.

[0062] The eleventh embodiment of this application also provides a terminal device (not shown). The mobile terminal includes the camera module 1 described in the tenth embodiment. The terminal device in this embodiment can be a mobile phone. It is understood that in other embodiments, the terminal device can also be a vehicle recorder, security monitoring equipment, AR device, VR device, vehicle, tablet computer, smartwatch, smart glasses, robot vacuum cleaner, or other devices with camera module 1.

[0063] In the terminal device provided in this embodiment, the connecting part 12 of the buffer 10 in the camera module 1 is connected to the lens carrier 200. The buffer part 14 of the buffer 10 faces the module housing 100. The driving member 400 drives the lens carrier 200 to move. When the other end of the buffer part 14 impacts the module housing 100, since the first distance 152 of any cross section 143 of the buffer part 14 is less than the second distance 153, that is, the buffer part 14 is not solid from the connecting surface 121 to the virtual surface 151, so that the buffer part 14 has a buffer gap 16 from the connecting surface 121 to the virtual surface 151.
