Description

Technical Field

[0001] The present invention relates to the field related to massage equipment, and in particular to a massage chair armrest and a massage chair using the armrest. Background Art

[0002] Massage chairs utilize mechanical rolling and squeezing forces to massage. Manual massage can dredge meridians, promote blood circulation, and maintain the body's yin and yang balance. This results in relaxed muscles, flexible joints, a refreshing feeling, and fatigue relief, all of which play a significant role in maintaining good health. Existing massage chairs primarily massage the torso. There are two main types of arm massage: one uses an inflatable airbag to clamp the user's arm, creating a pressure change as the airbag wraps around the user's arm; the other uses a traditional rotating massage ball.

[0003] Traditional massage chairs and their armrests have the following shortcomings: For massage chairs with massage balls in the armrest part, firstly, since the user needs to rest his arms on the massage balls during massage, most traditional massage chairs have difficulty in solving the problem of hiding the massage balls, resulting in users resting their arms on the uneven surface of the massage balls when they do not want to massage their arms, causing physical discomfort, thereby reducing the overall massage and relaxation experience of the massage chair; secondly, a few massage chairs that can hide the massage balls use a more complicated structure to hide and expose the massage balls, resulting in a more complicated structure of the massage chair armrests, making it difficult for users to easily take out and hide the massage balls, or it is difficult to ensure that the massage ball part and the armrest seat part of the massage chair remain integrated when the massage ball is hidden, and that the massage ball part can just protrude from the massage chair armrest to massage the user's arm when the massage ball is exposed. Summary of the Invention

[0004] Based on this, it is necessary to provide a massage chair armrest and a massage chair using the armrest to address the existing technical problems.

[0015] Preferably, a third transverse axis and a fourth transverse axis are also axially connected in the middle of the two fixed plates on each side, and the second transmission mechanism includes two identical gears and two sets of transmission pulleys with consistent structures corresponding to the two first transverse axes respectively. The two gears are meshed with each other and are coaxially fixed to the third transverse axis and the fourth transverse axis respectively. One set of transmission pulleys is connected to the third transverse axis and one of the first transverse axes, and the other set of transmission pulleys is connected to the fourth transverse axis and the other first transverse axis.

[0016] Preferably, a hexagonal prism slot for being fixedly connected to the active rotating shaft is provided at one end of the cover plate.

[0017] Preferably, four evenly distributed fixing frames are fixedly provided in the box body, and four vertical shafts corresponding to the four fixing frames are fixedly connected to the lifting horizontal plate. Each of the fixing frames is fixedly connected with a linear bearing for slidingly cooperating with the corresponding vertical shaft, and each of the vertical shafts is slidably provided in the corresponding linear bearing along the vertical direction.

[0018] Preferably, the top of the box body is also fixedly connected to an auxiliary horizontal plate for supporting the arm, the auxiliary horizontal plate is located directly above the lifting horizontal plate and is provided with a plurality of avoidance grooves corresponding to a plurality of avoidance members. The massage member is a multi-massage ball rotating plate axially arranged on the top of the lifting horizontal plate, and the driving mechanism includes a driving motor fixedly arranged at the bottom of the lifting horizontal plate and a plurality of transmission shafts for transmitting and connecting the plurality of multi-massage ball rotating plates and the output shaft of the driving motor.

[0019] A massage chair using the armrest comprises the above-mentioned massage armrest, and the massage armrest is embedded in the massage chair armrest seat, ensuring that the massage chair armrest seat and the top of the cover plate are flush when the armrest box is closed.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

Implementation Method

[0041] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] refer to Figures 1 to 16 A massage chair armrest shown, comprising:

[0043] The armrest box comprises a box body 1, a driving shaft 2 axially connected to the box body 1, and a cover plate 3 having one end fixedly connected to the driving shaft 2 and used for flipping open and closing;

[0044] The lifting horizontal plate 4 is slidably arranged in the box body 1 along the vertical direction;

[0045] The massage assembly includes a plurality of massage elements axially connected to the top of the lifting horizontal plate 4 and used for massaging the arms, and a drive mechanism 5 for driving the plurality of massage elements to rotate synchronously, wherein the drive mechanism 5 is fixedly disposed at the bottom of the lifting horizontal plate 4;

[0046] Two sets of linkage mechanisms 6 are symmetrically arranged in the box body 1. Each set of linkage mechanisms 6 includes a fixing part fixedly arranged in the box body 1, two symmetrical special-shaped handles 7 with one end hingedly arranged on the fixing part, and a reduction transmission mechanism that transmits and connects the corresponding ends of the active rotating shaft 2 with the hinged ends of the two special-shaped handles 7. The reduction transmission mechanism is used to drive the corresponding two special-shaped handles 7 to rotate after the cover plate 3 is opened, thereby lifting the lifting horizontal plate 4;

[0047] Among them, the lifting cross plate 4 is mounted on four hinged handles and rises and falls with the rotation of the free ends of the four hinged handles. In each of the linkage mechanisms 6, the corresponding special-shaped handles 7 are formed with mutually perpendicular high-position load-bearing surfaces 8 and low-position load-bearing surfaces 9. The high-position load-bearing surfaces 8 and the low-position load-bearing surfaces 9 are respectively used to press against and support the lifting cross plate 4 when the cover 3 is fully opened and fully closed. The corresponding special-shaped handle 7 is also axially provided with a pulley 10 for slidingly cooperating with the lifting cross plate 4 during the lifting process of the lifting cross plate 4. When the cover 3 is fully opened and fully closed, the distance between the two pulleys 10 is not equal to the distance between the hinged ends of the two special-shaped handles 7, so that the lifting cross plate 4 and the cover 3 can be locked with each other.

[0048] When the massage component is not needed for massage, the user can manually flip the cover plate 3 so that the cover plate 3 is in a fully closed state, and then the lifting horizontal plate 4 drives the massage component to fall into the box body 1. When the user needs to use several massage parts, the cover plate 3 can be flipped open so that the cover plate 3 is in a fully open state. The cover plate 3 will drive the active shaft 2 to rotate during the opening process, and then drive the two special-shaped handles 7 in the corresponding linkage mechanism 6 to rotate through each reduction transmission mechanism. During the rotation of the special-shaped handle 7, the low-position bearing surface 9 gradually separates from the bottom of the lifting horizontal plate 4, and the pulley 10 slides close to the bottom of the lifting horizontal plate 4, while supporting the lifting horizontal plate 4 upward, and the high-position bearing surface 8 gradually approaches the bottom of the lifting horizontal plate 4. When the lifting horizontal plate 4 rises to the highest point, the cover plate 3 is about to In the fully open state (but not yet fully open), the high-position load-bearing surface 8 is about to completely fit the bottom of the lifting horizontal plate 4, and at this time the distance between the two pulleys 10 is equal to the distance between the hinged ends of the two special-shaped handles 7 (that is, the axis of the pulley 10 on each special-shaped handle 7 rotates to be in the same vertical plane as the axis of the hinged end of the special-shaped handle 7. At this time, the pulley 10 is at the highest point, that is, the lifting horizontal plate 4 is lifted to the highest point), and then the cover 3 continues to rotate a little to fully open, so that the high-position load-bearing surface 8 of the special-shaped handle 7 is completely fit to the bottom of the lifting horizontal plate 4, and the height of the pulley 10 will be lowered a little during this process. When the cover 3 is fully opened, the gravity of the lifting horizontal plate 4 and the massage component acts completely on the four special-shaped handles 7, and through two reduction transmission mechanisms The cover 3 is brought to a corresponding torque, and the cover 3 is now fully opened and cannot rotate in the direction of the open state (rotation in the opening direction, i.e., the rotation direction is the same as the rotation direction when the cover 3 is opened), and can only rotate in the direction of the closed state (rotation in the closing direction, i.e., the rotation direction is opposite to the rotation direction when the cover 3 is opened, i.e., the rotation direction is the same as the rotation direction when the cover 3 is closed). As a result, a self-locking force is formed between the gravity of the lifting horizontal plate 4 and the massage component and the cover 3, so that the lifting horizontal plate 4 will not automatically fall or rise (the lifting horizontal plate 4 and the massage component have their own weight, and the user will also put his arms on several massage parts during massage, which will further increase the downward pressure of the lifting horizontal plate 4 on the four special-shaped rotating handles 7 When the cover plate 3 is to be moved, the cover plate 3 can only be rotated in the direction of the closed state. When the cover plate 3 is rotated in the closed state, the active rotating shaft 2 will be driven to rotate in the opposite direction, and the corresponding two special-shaped rotating handles 7 will be driven to rotate in the opposite direction through each reduction transmission component. During the reverse rotation of each special-shaped rotating handle 7, the lifting horizontal plate 4 will be driven to rise a little first, so that the axis of the pulley 10 and the axis of the hinged end of the special-shaped rotating handle 7 are in the same vertical plane again. Then, as the special-shaped rotating handle 7 continues to rotate, the lifting horizontal plate 4 begins to descend and gradually descends to the lowest point. When the lifting horizontal plate 4 descends to the lowest point, it is completely pressed on the low-position bearing surfaces 9 of the four special-shaped rotating handles 7. At this time, the cover plate 3 is completely flipped to the closed state, and the dead weight of the lifting horizontal plate 4 and the massage component interacts with the cover plate 3 again.The cover 3 will not open automatically, and the user needs to apply a certain amount of external force to open it. This ensures that the cover 3 and the box body 1 are in a tightly closed state, making it convenient for the user to rest their arms on the armrest box. At the same time, it can protect the lifting horizontal plate 4, massage components and two sets of linkage mechanisms 6 in the box body 1. In addition, the end of the cover 3 away from the active rotating shaft 2 is also formed with a slightly outward convex rib structure to facilitate the user to open it.

[0049] In order to install four special-shaped handles 7 in the box body 1, the following features are specifically set:

[0050] The box body 1 is a long box-shaped structure with an open top. The length direction of the lifting horizontal plate 4 is parallel to the length direction of the box body 1. The two groups of linkage mechanisms 6 are symmetrically arranged on both sides of the width direction of the lifting horizontal plate 4. The two special-shaped turning handles 7 in each linkage mechanism 6 are symmetrically arranged on both sides of the length direction of the lifting horizontal plate 4. The fixing parts are two symmetrically arranged fixing plates 11 fixedly connected to the box body 1, and two first horizontal axes 12 corresponding to the two special-shaped turning handles 7 are axially connected on both sides of the two fixing plates 11. The hinged ends of the special-shaped turning handles 7 and the two fixing plates 11 are fixedly connected to the corresponding first horizontal axes 12, and the corresponding reduction transmission mechanisms are arranged on the two fixing plates 11.

[0051] The corresponding ends of the two special-shaped turning handles 7 are respectively fixedly connected to the two first transverse shafts 12, and the two first transverse shafts 12 are axially connected to the two fixed plates 11, so that the corresponding ends of the two special-shaped turning handles 7 are hingedly set on the two fixed plates 11, and the special-shaped turning handles 7 are Figure 13 、 Figure 14 and Figure 16 The structure shown in the figure has a side profile similar to a question mark, and as shown in the figure Figure 16 As shown, the high-position bearing surface 8 and the low-position bearing surface 9 of the special-shaped handle 7 are tangent to the outer cylindrical wall of the pulley 10, so that when the lifting cross plate 4 is close to the high-position bearing surface 8 and the low-position bearing surface 9, the pulley 10 also contacts the bottom of the lifting cross plate 4, and the pulley 10 always contacts the bottom of the lifting cross plate 4 during the rotation of the special-shaped handle 7, thereby making the special-shaped handle 7 able to slide more smoothly at the bottom of the lifting cross plate 4, and referring to Figure 11 、 Figure 13 and Figure 16 It is easy to know that the hinged position of the special-shaped handle 7 and the two fixed plates 11 is located between the pulley 10 and the high-position load-bearing surface 8 and close to the high-position load-bearing surface 8, and when the special-shaped handle 7 rotates to Figure 16 When the cover 3 is fully opened ( Figure 16(not shown in the figure), when the special-shaped handle 7 rotates to the left around the axis of its hinged end, since the high-position bearing surface 8 and the pulley 10 both rotate around the axis of the hinged end of the special-shaped handle 7, during the initial rotation of the special-shaped handle 7, it is easy to see that the height of the high-position bearing surface 8 will be lower than the height of the pulley 10 as a whole, that is, the subsequent four pulleys 10 will press against the bottom of the lifting horizontal plate 4 and lift the lifting horizontal plate 4 a little until Figure 16 When the middle pulley 10 rises to the same vertical plane as the hinged end of the special-shaped turning handle 7, the pulley 10 rises to the highest point. Only after continuing to rotate will the pulley 10 drop and drive the lifting cross plate 4 to start dropping. That is to say, when the cover 3 is fully opened, due to the deadweight of the lifting cross plate 4 and the massage component, the lifting cross plate 4 will exert a certain downward pressure on the high-position load-bearing surface 8 of the special-shaped turning handle 7, and then there is a tendency to drive the cover 3 to continue to open, but the cover 3 is already in the limit position and cannot be opened anymore. Therefore, there will be a self-locking force between the lifting cross plate 4, the massage component and the cover 3. Unless there is an external force to drive the cover 3 to close, the lifting cross plate 4 can always maintain this height without rising or falling.

[0052] In order to connect the box body 1, the driving shaft 2 and the reduction transmission mechanism, the following features are specifically set:

[0053] Each of the reduction transmission mechanisms includes a first transmission mechanism for transmitting and connecting one of the first transverse shafts 12 and the corresponding end of the active rotating shaft 2, and a second transmission mechanism for transmitting and connecting the corresponding two first transverse shafts 12. Both ends of one side in the top length direction of the box body 1 are fixedly connected with hinged ears 13 for connecting the active rotating shaft 2. Each of the hinged ears 13 is also provided with a mounting groove 14 and a cover 15 is fixedly connected to the mounting groove 14. The two ends of the active rotating shaft 2 are respectively inserted into the two hinged ears 13 and inserted into the two mounting grooves 14. The two ends of the active rotating shaft 2 are respectively axially connected to the two hinged ears 13, and the parts of the active rotating shaft 2 inserted into the two mounting grooves 14 are respectively connected to the two second transmission mechanisms.

[0054] After the active rotating shaft 2 rotates, the two corresponding first transverse shafts 12 are driven to rotate through the two first transmission mechanisms. After the corresponding first transverse shaft 12 rotates, the other first transverse shaft 12 on the same side is driven to rotate through the corresponding second transmission mechanism. In this way, after the active rotating shaft 2 rotates, the four first transverse shafts 12 are driven to rotate respectively, and then the four special-shaped rotating handles 7 are driven to rotate.

[0055] In order to connect the driving shaft 2 and the corresponding first transverse shaft 12 through the first transmission mechanism, the following features are specifically provided:

[0056] The two fixed plates 11 on each side are also axially connected to a second transverse shaft 16 at one end close to the driving shaft 2. The first transmission mechanism includes a first reduction pulley 17 that is transmission-connected to the driving shaft 2 and the second transverse shaft 16, and a second reduction pulley 18 that is transmission-connected to the second transverse shaft 16 and the corresponding first transverse shaft 12.

[0057] The structures of the first reduction pulley 17 and the second reduction pulley 18 are consistent. The first reduction pulley 17 includes two transmission wheels, one large and one small, and a transmission belt connecting the two transmission wheels. The two transmission wheels are coaxially fixed with the corresponding ends of the active rotating shaft 2 and the corresponding first horizontal axis 12 (the mounting groove 14 on the hinged ear 13 is used to facilitate the connection of the corresponding transmission wheel to the active rotating shaft 2). The first reduction pulley 17 is used to amplify the torque of the active rotating shaft 2 to the second rotating shaft, and the second reduction pulley 18 is used to amplify the torque of the second rotating shaft to the corresponding first rotating shaft. This can ensure that the user can flip the cover 3 more easily, and can also solve the problem that the stroke of the cover 3 is large during the flipping process and the stroke of the lifting horizontal plate 4 is small during the lifting process.

[0058] In order to connect the corresponding two first transverse shafts 12 through the second transmission mechanism, the following features are specifically provided:

[0059] A third transverse axis 19 and a fourth transverse axis 20 are also axially connected in the middle of the two fixed plates 11 on each side. The second transmission mechanism includes two identical gears 21 and two sets of transmission pulleys 22 with the same structure and corresponding to the two first transverse axes 12 respectively. The two gears 21 are meshed with each other and are coaxially fixed to the third transverse axis 19 and the fourth transverse axis 20 respectively. One set of transmission pulleys 22 is transmission-connected to the third transverse axis 19 and one of the first transverse axes 12, and the other set of transmission pulleys 22 is transmission-connected to the fourth transverse axis 20 and the other first transverse axis 12.

[0060] The transmission pulley 22 is a pulley with a transmission ratio of one to one, which includes two transmission wheels with the same diameter and a transmission belt connecting the two transmission wheels, and the two transmission pulleys 22 and the two gears 21 are as shown in FIG. Figures 11 to 15 As shown, the third transverse axis 19, the fourth transverse axis 20 and the two first transverse axes 12 are connected, so that it can be achieved that the two special-shaped turning handles 7 rotate synchronously and at the same speed, and the two special-shaped turning handles 7 turn in opposite directions. In addition, the two special-shaped turning handles 7 are symmetrically arranged, which can ensure that the force of the lifting horizontal plate 4 is balanced when it is raised and lowered.

[0061] In order to connect the cover plate 3 and the active shaft 2, the following features are specifically set:

[0062] One end of the cover plate 3 is provided with a hexagonal column slot 23 for being fixedly connected to the driving shaft 2 .

[0063] When the cover plate 3 is in the fully closed state, it is horizontally covered on the top of the box body 1. After the cover plate 3 rotates two hundred and seventy degrees around the axis of the active rotating shaft 2 from the fully closed state, it fits against the corresponding side wall of the box body 1 and is in the fully open state. When the cover plate 3 is in the fully closed state, under the action of the deadweight of the lifting horizontal plate 4 and the massage component, the cover plate 3 is pressed downward on the top of the box body 1. When the cover plate 3 is in the fully open state, under the action of the deadweight of the lifting horizontal plate 4 and the massage component (and the gravity of the user's arm during massage), the cover plate 3 is laterally pressed against the corresponding side outer wall of the box body 1.

[0064] In order to enable the lifting horizontal plate 4 to slide in the vertical direction inside the box body 1, the following features are specifically provided:

[0065] Four evenly distributed fixing frames 24 are fixedly arranged in the box body 1, and four vertical shafts 25 corresponding to the four fixing frames 24 are fixedly connected to the lifting horizontal plate 4. Each of the fixing frames 24 is fixedly connected to a linear bearing 26 for slidingly cooperating with the corresponding vertical shaft 25, and each of the vertical shafts 25 is slidably arranged in the corresponding linear bearing 26 along the vertical direction.

[0066] Through the cooperation of the four vertical shafts 25, the linear bearings 26 and the fixing frame 24, it can be ensured that the lifting horizontal plate 4 can only be lifted and lowered in the vertical direction. In combination with the rotational movement of the four special-shaped handles 7, the lifting horizontal plate 4 can be lifted and lowered smoothly.

[0067] In order to drive the multiple massage elements to rotate synchronously through the drive mechanism 5 and ensure support for the user's arms during massage, the following features are specifically set:

[0068] The top of the box body 1 is also fixedly connected to an auxiliary horizontal plate 27 for supporting the arm. The auxiliary horizontal plate 27 is located directly above the lifting horizontal plate 4 and is provided with a plurality of avoidance grooves 28 corresponding to a plurality of avoidance members. The massage member is a multi-massage ball rotating plate 29 axially arranged on the top of the lifting horizontal plate 4. The driving mechanism 5 includes a driving motor 30 fixedly arranged at the bottom of the lifting horizontal plate 4 and a plurality of transmission shafts 31 for transmitting and connecting the plurality of multi-massage ball rotating plates 29 and the output shaft of the driving motor 30. A switch button 32 electrically connected to the driving motor 30 is also provided outside the box body 1.

[0069] The multi-massage ball rotating plate 29 is Figure 6The structure shown in the figure has multiple convex spherical structures formed on the top. After the user's arm is placed on several multi-massage ball rotating plates 29, the rotation of the multi-massage ball rotating plates 29 can massage the user's arm. The output shaft of the drive motor 30 drives the multiple multi-massage ball rotating plates 29 to rotate synchronously through the transmission connection of several transmission shafts 31. The transmission shafts 31 and the drive motor 30 and the transmission shafts 31 are all connected by bevel gear transmission. The auxiliary cross plate 27 is used to support the arm at a position where the multiple massage ball rotating plates 29 cannot contact the user's arm. When the user needs to use several multi-massage ball rotating plates 29 for massage, he can start the drive motor 30 by pressing the switch button 32, thereby driving the multiple multi-massage ball rotating plates 29 to rotate.

[0070] A massage chair using the armrest is embedded in the armrest seat of the massage chair, ensuring that the armrest seat of the massage chair is flush with the top of the cover plate 3 when the armrest box is closed.

[0071] Working principle: When the massage component is not needed for massage, the user can manually flip the cover plate 3 so that the cover plate 3 is in a fully closed state, and then the lifting horizontal plate 4 drives the massage component to fall into the box body 1. When the user needs to use several massage parts, the cover plate 3 can be flipped open so that the cover plate 3 is in a fully open state. During the opening process of the cover plate 3, the active rotating shaft 2 will be driven to rotate, and then the two special-shaped rotating handles 7 in the corresponding linkage mechanism 6 will be driven to rotate through each reduction transmission mechanism. During the rotation of the special-shaped rotating handle 7, the low-position load-bearing surface 9 gradually separates from the bottom of the lifting horizontal plate 4, and the pulley 10 slides close to the bottom of the lifting horizontal plate 4, while supporting the lifting horizontal plate 4 upward, and the high-position load-bearing surface 8 gradually approaches the bottom of the lifting horizontal plate 4. When the lifting horizontal plate 4 is raised to After the highest point, the cover plate 3 is about to be in a fully open state (but has not yet reached the fully open state), the high-position load-bearing surface 8 is about to be completely in contact with the bottom of the lifting horizontal plate 4, and at this time the distance between the two pulleys 10 is equal to the distance between the hinged ends of the two special-shaped handles 7 (that is, the axis of the pulley 10 on each special-shaped handle 7 is rotated to be in the same vertical plane as the axis of the hinged end of the special-shaped handle 7. At this time, the pulley 10 is at the highest point, that is, the lifting horizontal plate 4 is lifted to the highest point), and then the cover plate 3 continues to rotate a little to fully open, so that the high-position load-bearing surface 8 of the special-shaped handle 7 is completely in contact with the bottom of the lifting horizontal plate 4, and the height of the pulley 10 will be lowered a little during this process. When the cover plate 3 is fully opened, the gravity of the lifting horizontal plate 4 and the massage component acts completely on the four special-shaped handles The handle 7 is on the handle 7, and the corresponding torque is applied to the cover plate 3 through the two reduction transmission mechanisms. At this time, the cover plate 3 is fully opened and can no longer rotate in the direction of the open state (rotating in the opening direction, that is, the rotation direction is the same as the rotation direction when the cover plate 3 is opened), and can only rotate in the direction of the closed state (towards the closed state, that is, the rotation direction is opposite to the rotation direction when the cover plate 3 is opened, that is, the rotation direction is the same as the rotation direction when the cover plate 3 is closed). As a result, a self-locking force is formed between the gravity of the lifting horizontal plate 4 and the massage component and the cover plate 3, so that the lifting horizontal plate 4 will not automatically fall or rise (the lifting horizontal plate 4 and the massage component have their own weight, and the user will also put his arms on several massage parts during massage, which will further When the cover plate 3 is moved, the driving shaft 2 is driven to rotate in the opposite direction, and the corresponding two special-shaped handles 7 are driven to rotate in the opposite direction through each reduction transmission component. During the reverse rotation of each special-shaped handle 7, the lifting cross plate 4 is driven to rise a little first, so that the axis of the pulley 10 and the axis of the hinged end of the special-shaped handle 7 are in the same vertical plane again. Then, as the special-shaped handle 7 continues to rotate, the lifting cross plate 4 begins to descend and gradually descends to the lowest point. When the lifting cross plate 4 reaches the lowest point, it is completely pressed on the low-position bearing surfaces 9 of the four special-shaped handles 7, and at this time the cover plate 3 is completely flipped to the closed state.The weight of the lifting plate 4 and the massage component interacts with the cover 3 again, preventing the cover 3 from opening automatically. The user needs to apply a certain external force to open it. This ensures that the cover 3 and the box body 1 are in a tightly closed state, making it convenient for the user to rest their arms on the armrest box. At the same time, it can protect the lifting plate 4, the massage component, and the two sets of linkage mechanisms 6 inside the box body 1.
