Description

Technical Field

[0001] The present application relates to the technical field of electronic components, and in particular to a circuit board of a neck massager. Background Art

[0002] As people's requirements for quality of life continue to improve, massage experience is becoming more and more popular, because massage can relax muscles and blood circulation, relieve fatigue, and make people relax, especially for office workers who sit in the office for a long time. However, it seems unrealistic to equip the workstation with a massager, so the small neck massager becomes the first choice. However, with the iteration of products and technologies, the size of neck massagers is getting smaller and smaller, and in order to fit the contour of the neck, the shell of the massager will have a curvature, and the installation space reserved for the internal circuit board is relatively small, so the circuit board has to be made into narrow strips or divided into multiple pieces, which is not convenient during installation. Summary of the invention

[0003] The purpose of the present application is to provide a circuit board for a neck massager with higher space utilization in a massager housing.

[0004] In order to achieve the above purpose, the present application provides a neck massager circuit board: including a PCB substrate, the upper side of the PCB substrate has a concave neck arc groove, the lower side of the PCB substrate has a concave back arc groove, the left and right sides of the PCB substrate are provided with straight card grooves, and the PCB substrate has an oblique card groove in the neck arc groove, which is used to fit with the card block structure in the massager shell to play a role in pre-positioning of the installation.

[0005] As a preferred embodiment, there are two oblique slots, and the two oblique slots are symmetrically distributed in the neck arc groove to ensure balanced force on the left and right sides.

[0006] As a preference, the longitudinal depth of the neck arc groove is greater than the longitudinal depth of the back arc groove, which is similar to the ergonomic structure of the massager housing and fits closely to the neck contour of the wearer.

[0007] As a preference, the lateral width of the neck arc groove is smaller than the lateral width of the back arc groove, which is similar to the ergonomic structure of the massager housing and fits closely to the upper contour of the wearer's trapezius muscle.

[0008] As a preference, the center of the front side of the PCB substrate is a main configuration area, and the front side of the PCB substrate is further provided with auxiliary configuration areas located on the left and right sides of the main configuration area, so as to plan a regular welding area for the electrical components.

[0009] As a preference, the PCB substrate is provided with preset holes in the main configuration area and the auxiliary configuration area, and the preset holes penetrate the front and rear sides of the PCB substrate to facilitate the metal pins of the electrical components to pass through for welding.

[0010] Preferably, the PCB substrate is provided with connection holes in a portion outside the main configuration area and the auxiliary configuration area, and the connection holes pass through the front and rear sides of the PCB substrate for connecting parts to pass through and fix the entire circuit board in the massager housing.

[0011] As a preference, the oblique slot is located within an area enclosed by a transverse boundary line of the main configuration area and a longitudinal boundary line of the auxiliary configuration area, so as to fully utilize an unused area on the PCB substrate.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By designing a concave top and concave bottom structure for the circuit board, it is adapted to the massager housing that conforms to the ergonomic design principle, so that the internal space of the massager housing is more fully utilized, and the circuit board is installed in the massager housing more stably and firmly;

[0014] (2) By performing multi-zone separation on the PCB substrate, not only can the layout of the configured electrical components be more regular, but also the space utilization on the PCB substrate 1 can be improved by opening grooves or holes in places that cannot be covered by the configuration area.

[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0025] like Figure 1-5 The neck massager circuit board shown, including a PCB substrate 1, can be made into a backward-leaning arc-shaped plate, but the arc-shaped plate is not convenient for configuring the electrical unit, so the conventional flat plate structure is still adopted in this embodiment. The upper side of the PCB substrate 1 has a concave neck arc groove 3, which is close to the wearer's neck arc, and the lower side of the PCB substrate 1 has a concave back arc groove 4, which is close to the arc of the trapezius muscle at the transition between the wearer's neck and back. The longitudinal depth of the neck arc groove 3 is greater than the longitudinal depth of the back arc groove 4, which leaves more depth for the wearer's backward neck, and the lateral width of the neck arc groove 3 is less than the lateral width of the back arc groove 4, which adapts to the wearer's wider back arc.

[0026] Since the PCB substrate 1 has the groove structure in the up and down directions, the shape of the entire circuit board is close to a bow tie, that is, the left and right ends are large and the middle is small. In order to make full use of the space on the PCB substrate 1, the PCB substrate 1 will be adaptively partitioned. Specifically, the center of the front side of the PCB substrate 1 is the main configuration area 6, and then the auxiliary configuration areas 7 located on the left and right sides of the main configuration area 6 are set on the front side of the PCB substrate 1. The two auxiliary configuration areas 7 are symmetrical about the main configuration area 6, just occupying a larger space at both ends of the PCB substrate 1. The PCB substrate 1 is provided with preset holes 9 in the main configuration area 6 and the auxiliary configuration area 7. The preset holes 9 pass through the front and rear sides of the PCB substrate 1 for the metal pins of the configured electrical components to pass through, thereby realizing welding and fixing.

[0027] The PCB substrate 1 is provided with a connection hole 8 outside the main configuration area 6 and the auxiliary configuration area 7. The connection hole 8 runs through the front and rear sides of the PCB substrate 1 for the positioning column or the connector to pass through and fix the PCB substrate 1 in the massager housing. The left and right sides of the PCB substrate 1 are provided with straight card slots 2, which fit with the convex block structure inside the massager housing to limit the movement of the PCB substrate 1. The PCB substrate 1 is provided with an oblique card slot 5 in the neck arc groove 3, which has a similar function to the straight card slot 2, except that the extension direction of the oblique card slot 5 has a certain angle with the longitudinal and transverse directions and is inclined. There are two oblique card slots 5, which are symmetrically distributed in the neck arc groove 3 in an eight-shaped shape. Moreover, the oblique card slot 5 is located within the area surrounded by the transverse boundary line of the main configuration area 6 and the longitudinal boundary line of the auxiliary configuration area 7. Because this part is a place that the rectangular main configuration area 6 cannot cover, it is a special-shaped area and is not suitable for configuring regular electrical components. However, the oblique card slot 5 can make full use of this part of the material and space.

[0028] Working principle: The neck massager is an embracing structure, and the rear part of its shell also has a top concave and bottom concave structure similar to the PCB substrate 1, which conforms to the ergonomic design principle and makes the wearer more comfortable when using the massager. Before installation, the circuit board first welds the required electronic components in the corresponding configuration area on the PCB substrate 1 through the preset holes 9, and then aligns the card slot structure on the side of the PCB substrate 1 with the positioning card block structure in the massager shell, and then fixes it with the connector, and finally electrically connects the cable to the driving mechanism of the massager to complete the installation.

[0029] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
