Description

Technical Field

[0001] The utility model relates to the field of massage devices, in particular to a slide rail type massage mechanism, a massage cushion and a sofa. Background Art

[0002] The existing massage cushion includes a cover assembly and a slide rail type massage mechanism disposed inside the cover assembly. The slide rail type massage mechanism generally includes a slide rail and a massage core, the massage core is slidably disposed on the slide rail, a motor and a motor control module are installed inside the massage core, and the motor control module is connected to an external power supply and a human-computer interaction module (such as a key module) through a flexible wire.

[0003] The existing massage pad has the following problems: when the massage mechanism slides up and down along the slide rail, the flexible wire will move back and forth with the massage mechanism. After long-term use, the flexible wire is prone to damage or even disconnection, which affects the service life of the massage mechanism. In addition, in order to ensure that there is space inside the outer cover assembly for the flexible wire to move back and forth, the outer cover assembly needs to be provided with a certain support frame, which makes the volume of the massage pad larger and also easily makes the massage pad harder at the support frame, affecting comfort.

[0004] Although there are some massage pad products on the market that use power supply slide rail mechanisms instead of flexible wires, the following problems still exist: the power supply slide rail mechanism is set separately from the slide rail of the transmission connection, which causes the volume of the massage mechanism to increase, and then the volume of the massage pad product to increase; more seriously, the two conductive parts of the power supply slide rail mechanism are separated for a short time during the sliding process due to vibration, wear and other reasons, resulting in a momentary disconnection of the electrical connection, making it difficult to always maintain the electrical connection. The motor control module set inside the massage movement needs to have stable power supply and communication. The momentary disconnection of the electrical connection will cause it to work abnormally, and then the entire massage mechanism will stop running. Therefore, it is necessary to design a new slide rail massage mechanism and massage pad to solve the above problems. Summary of the invention

[0009] The slide rail is provided with a first guide groove extending along its length direction, and the conductive member is fixedly arranged inside the first guide groove; the housing of the massage movement is provided with two first guide strips in parallel and spaced apart from each other, and the conductive spring sheet is fixedly arranged between the two first guide strips; the two first guide strips are slidably embedded in the first guide groove.

[0010] Furthermore, the conductive spring sheet is arranged along the length direction of the slide rail with a first arc-shaped curved portion, a second arc-shaped curved portion and another first arc-shaped curved portion, and the two first arc-shaped curved portions are higher than the second arc-shaped curved portion for contacting the conductive member.

[0011] Furthermore, the slide rail is provided with a second guide groove between the rack and the conductive component, and the housing is provided with a second guide bar, and the second guide bar is slidably embedded in the second guide groove.

[0012] Furthermore, the housing of the massage movement includes a rear housing, a front housing and a side housing, the rear housing and the front housing are interlocked with each other, the motor and the gear set are assembled therein, and the massage part is assembled on the front housing; the left and right ends of the rear housing are provided with extension parts, the left and right ends of the front housing are fixedly connected with the side housing, the other end of the side housing is fixedly connected to the rear housing, and the slide rail can be slidably arranged between the extension part and the side housing; at least one extension part is fixedly provided with the conductive spring sheet.

[0013] Furthermore, the side shell is provided with a plurality of convex strips at the end surface contacting the slide rail.

[0014] Furthermore, the first guide strip is provided with a plurality of first avoidance grooves on the end surface contacting the first guide groove.

[0015] Furthermore, the second guide strip is provided with a plurality of second avoidance grooves on the end surface contacting the second guide groove.

[0021] A sofa comprises a massage cushion with the structure as described above.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] First, compared to the case where the motor control module is built into the massage movement, the utility model sets the motor control module outside the massage movement, and electrically connects the motor control module to the motor inside the massage movement through the conductive member and the conductive spring, without the need to arrange flexible wires, and has the advantage of long service life. Setting the motor control module outside the massage movement can avoid abnormal operation of the motor control due to the instantaneous disconnection of the conductive member and the conductive spring during the sliding contact process. In addition, setting the mechanical transmission gear and the electrically connected conductive member on the same slide rail can greatly reduce the product volume, making the product smaller and lighter than setting them separately.

[0024] Secondly, in the utility model, the conductive spring is arranged between the two first guide strips, and the conductive member is arranged in the first guide groove. The sliding embedding of the two first guide strips and the first guide groove is utilized to ensure that the conductive spring is always aligned with the conductive spring during the sliding process of the massage movement, and the conductive spring and the conductive member are well protected, making the electrical connection more reliable and durable.

[0025] Third, in the utility model, the conductive spring is provided with two first arc-shaped bends, and there is also a second arc-shaped bend between the two first arc-shaped bends. The two first arc-shaped bends are used to abut against the conductive member, so that the conductive spring has two electrical connection points, thereby improving the stability of the electrical connection between the two. In order to ensure the stability of the electrical connection, when the second arc-shaped bend abuts against the conductive spring, the conductive spring must be in an elastic deformation state, and the second arc-shaped bend can well control the influence range of the elastic deformation, thereby reducing the mutual influence of the two second arc-shaped bends when deformation occurs. In addition, a boss is provided between the two first guide strips, which is used to abut against the back of the two ends of the second arc-shaped bend to support the conductive spring, thereby further making the electrical connection between the conductive spring and the conductive member more stable and reliable.

[0026] Fourthly, the utility model is also provided with a second guide groove and a second guide bar which cooperate with each other and are located between the conductive component and the rack. The sliding embedding of the second guide groove and the second guide bar can make the sliding connection between the slide rail and the massage movement more stable, ensure that the rack and the gear set always maintain a transmission connection relationship, avoid "tooth jumping", and also suppress the shaking generated when the rack and the gear set interact with each other, preventing the electrical connection between the conductive spring sheet and the conductive member from being affected.

[0027] Fifth, in the utility model, the housing of the massage movement includes a front housing, a rear housing and a side housing. The two ends of the side housing are detachably fixedly connected to the front housing and the rear housing, which is convenient for the installation and removal of the massage movement and the slide rail, and also convenient for the installation and removal of the conductive spring. In addition, the rear housing and the side housing are all-roundly sleeved on the outside of the slide rail, making the sliding of the massage movement more stable.

[0028] Sixth, in the present invention, the side housing is provided with a plurality of convex strips, the first guide strip is provided with a plurality of first avoidance grooves, and the second guide strip is provided with a plurality of second avoidance grooves. These designs can reduce the contact surface between the slide rail and the massage movement, and avoid the sliding of the two being stuck due to the entire contact surface.

[0029] Seventh, in the utility model, connecting posts are provided at both ends of the slide rail, and connecting rings are provided at both ends of the conductive member; the connecting rings are sleeved on the connecting posts to facilitate loading and unloading of the conductive member and keep the conductive member in a taut state, further making the electrical connection between the conductive spring and the conductive member more stable and reliable.
