Technical Field
[0001] This application relates to a vibration device, a seat, and a vehicle. Background Technology
[0002] Nowadays, some chair products are equipped with vibration devices that can output vibrations to users for purposes such as massage or sending signals through vibration, in order to enrich the functions of the chair products and improve the user experience.
[0003] Generally, a vibrating device is equipped with a vibrator as the vibration source. For example... Figure 7 As shown, in a comparative scheme, the vibration device 100a is equipped with a vibrator 120a at each vibration position to achieve output vibration to multiple vibration positions, so as to provide a better user experience.
[0004] However, the inventors of this application discovered that the comparative solution was heavy and costly, making it difficult to meet the requirements for lightweight and cost-reduced seating products. Therefore, the inventors propose a vibration device, a seat, and a vehicle that, while ensuring a good vibration experience for the seating product, further reduces the weight and cost of the seat.
[0005] The above description of the comparative solutions is for the purpose of providing a comparison with the solutions of the embodiments, and does not imply that the applicant believes the comparative solutions are prior art. Utility Model Content

[0035] It is understood that the vibration device and seat provided in this application are particularly suitable for automobiles, but can also be applied to other applicable occasions, such as railcars, ships, and aircraft, as well as applicable fixed places, such as meeting rooms, auditoriums, and cinemas. As long as the seat can use the vibration device disclosed in the embodiments of this application, it is not limited thereto.
[0036] like Figures 2 to 6A vibration device 100 is shown for vibrating a seat 10, comprising: a base 110 and at least one vibration unit; each vibration unit includes: a single vibrator 120 and a plurality of rods 130; wherein the base 110 provides a mounting position for the vibrator 120; the base 110 may be a plate or other shaped component, not limited thereto; the vibrator 120 refers to a device suitable for a seat that can generate vibration; the vibrator 120 may be configured to output appropriate vibrations for massage and / or signaling, etc.; the vibrator 120 may be an electric vibrator, a pneumatic vibrator, etc., for example, it may be equipped with an electromagnet and utilize electromagnetic force. A vibrator that drives a mass block to periodically translate or rotate to output vibration, but is not limited to this; a single vibrator 120 is connected to a base 110; each link 130 is connected to a fulcrum and can rotate (oscillate) around the fulcrum X, and the first position 131 of each link 130 is connected to the output end of the vibrator 120, and the second position 132 of each link 130 corresponds to a vibration output position; the vibration transmission path of each vibration unit includes: the single vibrator 120 generates vibration, and at the same time drives each link 130 to rotate around the fulcrum, so that each link 130 drives the vibrated object located at the vibration output position to vibrate at the second position 132.
[0037] like Figure 2 As shown, specifically, the vibration device 100 can be configured such that: a first position 131 of the rod 130 is located at one end of the rod 130 and connected to the vibrator 120; a second position 132 of the rod 130 is located at the other end and can move to the vibration output position to contact the object being vibrated; the axis of pivoting the rod 130 about the fulcrum is perpendicular to the vibration direction output by the vibrator 120, thus forming a lever-like structure. The vibration output by the vibrator 120 synchronously drives the rod 130 to swing back and forth about the fulcrum X, thereby controlling the vibration of the vibrator through the rod 130. The vibration output by 120 is transmitted to the object being vibrated, which may be the backrest 11 or the cushion 12 of the seat 10, but is not limited thereto; the vibration device 100 may also be other structures, such as the first position 131 and the second position 132 being located on the same side of the fulcrum X, but is not limited thereto; the object being vibrated may also be the filling layer inside the backrest 11 or the cushion 12, and the vibration output by the vibration device 100 may be transmitted through the filling layer to the surface of the backrest 11 or the cushion 12 so that it can be felt by the user, but is not limited thereto.
[0038] The vibration device 100 described above transmits the vibration generated by a single vibrator 120 through multiple rods 130 in the vibration unit, enabling vibration to be triggered at multiple vibration output positions using only a single vibrator 120. This expands the effective range of the single vibrator 120, eliminating the need for multiple vibrators to trigger vibration at these multiple output positions. It is understood that a single rod 130 typically has lower cost and weight than a single vibrator 120. Compared to using multiple vibrators 120 to output vibration at multiple vibration output positions, using a single vibrator 120 in conjunction with multiple rods 130 to output vibration at the same multiple vibration output positions ensures a similar user experience while reducing the number of vibrators, thus significantly reducing the overall weight and cost of the vibration device 100. For example, as... Figure 7 The comparative scheme shown has a vibration device 100a with four vibrators 120a to generate vibrations at four corresponding vibration output positions. Each vibrator 120a weighs approximately 80g, totaling approximately 320g. In contrast, the vibration device 100 of this application uses only a single vibrator 120, and transmits the vibration to the same four vibration output positions via four rods 130, achieving essentially the same vibration function experience. Furthermore, the weight of a single vibrator 120 is approximately 80g, and the weight of each rod is approximately 14g, totaling approximately 136g. Therefore, by reducing the number of redundant vibrators 120, the vibration device 100 of this application is approximately 184g lighter overall compared to the comparative scheme's vibration device 100a, demonstrating a significant weight reduction effect. Similarly, the vibration device 100 of this application, compared to… Figure 7 The comparison scheme shown can also reduce costs by about 75%, demonstrating a significant cost reduction effect.
[0039] like Figure 4 As shown, it can be understood that by using the rod 130 to rotate around the fulcrum X to transmit vibration, a structure similar to a lever can be formed. Utilizing the lever principle, the force and amplitude of the vibration output from the vibrator 120 can be changed after being transmitted through the rod 130, for example, by amplifying the vibration generated by the vibrator 120. Thus, by properly configuring the rod 130 and the fulcrum X, the vibration output by the vibration device 100 can achieve the desired effect.
[0040] like Figure 4 As shown, in one or more embodiments, the vibration device 100 is configured such that the fulcrum X is position-adjustable for vibration regulation. By configuring the fulcrum X, i.e., the fulcrum of the lever structure, as position-adjustable, the distance between the fulcrum X and the first position 131 and the second position 132 is changed by adjusting the position of the fulcrum X, thereby changing the force and amplitude of the vibration after it is transmitted through the rod 130, so as to improve the vibration effect; for example... Figure 4As shown, the fulcrum X is moved away from the vibrator 120 to increase the force transmitted by the rod 130, and the fulcrum X is moved closer to the vibrator 120 to increase the vibration amplitude transmitted by the rod 130.
[0041] like Figure 2 As shown, specifically, the vibration device 100 can be configured to include a support 111 corresponding to each rod 130, for example, the two are in one-to-one correspondence, the rod 130 is pivotally connected to the support 111 to form a fulcrum X, and the support 111 is positionally adjustable to the base 110 so that the fulcrum X is positionally adjustable; for example, the support 111 is configured to be detachably connected to the base 110 and the rod 130 respectively, and the base 110 and the rod 130 provide multiple mounting positions for mounting the support 111 so that the position of the fulcrum X is adjustable; the vibration effect output by the rod 130 can be adjusted by mounting the support 111 in different mounting positions, without limitation thereto.
[0042] like Figure 2 As shown, in one or more embodiments, the rod 130 is provided with a vibration head at the second position 132; the vibration head is used to contact the object being vibrated at the vibration output position to achieve effects such as increasing the contact area between the rod 130 and the object being vibrated; for example, the vibration head may have a circular contact plane whose area is approximately equivalent to the output end of the vibrator 120; the vibration head may also be other structures to provide different tactile experiences, and is not limited thereto.
[0043] like Figure 5 , Figure 6 As shown, in one or more embodiments, the vibration device 100 includes a plurality of vibration units, such as two vibration units, each vibration unit including two rods 130 connected to a single vibrator 120; each vibrator 120 may also output different vibrations simultaneously, not limited thereto.
[0044] In one or more embodiments, the vibration device 100 includes a single vibration unit, which includes a plurality of links 130, such as four links 130, each link 130 being connected to a single vibrator 120.
[0045] In one or more embodiments, the weight of a single vibrator is in the range of 60g to 100g; and / or, the weight of a single rod is in the range of 10g to 20g.
[0046] like Figure 2As shown, in one or more embodiments, the substrate 110 is a plate, and the vibration device 100 is configured such that the substrate 110 has a thinned portion or a first through portion 112 extending in its thickness direction. In other words, the substrate 110 has a reduced thickness dimension at the mounting position of the vibrator 120, or forms a through first through portion 112; the vibrator 120 is disposed inside the thinned portion or the first through portion 112; this facilitates full utilization of the space in the thickness direction of the substrate 110, making the vibration device 100 structure compact.
[0047] like Figure 2 As shown, in one or more embodiments, the base 110 is a plate, which includes a support 111 corresponding to each rod 130. The support 111 is connected to the base 110, and the rod 130 is connected to the support 111 to form a fulcrum X. The base 110 is provided with a second through portion 113 corresponding to the vibration output position. The rod 130 and the support 111 are disposed on one side of the base 110, and the vibration output position and the object being vibrated are located on the other side of the base 110. Furthermore, the vibration generated by the vibrator 120 drives the rod 130 to move, so that the second position 132 of the rod 130, such as the vibration head, can pass through the second through portion 113. The through portion 113 reaches the other side of the base 110 to contact the object being vibrated at the vibration output position; the second through portion 113 is, for example, a circular through hole as shown in the figure, but is not limited thereto, as long as the structure allows the second position 132 to pass through it to reach the other side of the base 110; by setting the rod 130 and the support 111 on one side of the base 110, and only allowing the second position 132 on the rod 130 to pass through the second through portion 113 to reach the other side, while realizing the output vibration to the object being vibrated, the user is prevented from feeling a foreign object due to the protrusion of the rod 130 and the support 111, thus improving the user experience.
[0048] like Figure 1 , Figure 3 A seat 10 is shown, which includes the aforementioned vibration device 100; wherein the vibration device 100 is disposed inside the backrest 11, and the vibration generated by the vibrator 120 is transmitted to the surface of the backrest 11 through the rod 130 so as to be felt by the user; and / or, the vibration device 100 is disposed inside the seat cushion 12, and the vibration generated by the vibrator 120 is transmitted to the surface of the seat cushion 12 through the rod 130 so as to be felt by the user; the vibration device 100 may also be disposed in other parts of the seat 10, but is not limited thereto.
[0049] like Figure 3As shown, in one or more embodiments, the base 110 is connected to the suspension structure 13 of the seat 10 to mount the vibration device 100; the base 10 may also be connected to the seat frame 14 via a filamentary member 114, but is not limited thereto; the filamentary member 114 is, for example, an elastic steel wire; the suspension structure 13 mentioned here refers to a support structure disposed inside the frame formed by the seat frame 14, which has a certain deformation (movement) capability, thereby improving the fit and support effect of the seat 10 to the user's body through deformation when providing support to the user. The suspension structure 13 can be an elastic spring with elastic steel wire, such as a serpentine spring, etc., and is not limited thereto; the base 110 can be provided with through holes, hooks and other connecting structures to be installed to the suspension structure 13 and / or the filamentous component 114; the vibration device 100 is installed in this way, and through the deformation (movement) of the suspension structure 13 and the filamentous component 114, the vibration device 100 can be supported and can also move to a certain extent, which is conducive to better conforming to the user's body, so that the vibration can be effectively transmitted to the user, and improve the user experience such as comfort.
[0050] In one or more embodiments, the backrest 11 is provided with a single vibration device 100; and / or, the seat cushion 12 is provided with a single vibration device 100.
[0051] like Figure 1 The vehicle 1 shown is, for example, an automobile, which includes the seat 10 described above.
[0052] In summary, the advanced technical effects of this application include, but are not limited to, at least one of the following:
[0053] By transmitting the vibration generated by a single vibrator through multiple rods in the vibration unit, vibration can be induced at multiple vibration output positions using only a single vibrator, thus expanding the effective range of a single vibrator. This eliminates the need for multiple vibrators to induce vibration at the same multiple vibration output positions, thereby reducing the number of vibrators and significantly lowering the weight and cost of the vibration device while maintaining essentially the same vibration function.
[0054] While this application discloses preferred embodiments as described above, it is not intended to limit the scope of this application. Any changes and modifications can be made by those skilled in the art without departing from the spirit and scope of this application.
