For ease of explanation, when detailing the embodiments of the present invention, the cross-sectional views showing the device structure are partially enlarged, not according to the general scale, and the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. Furthermore, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

It will be understood that these spatial relation terms are intended to include directions other than those depicted in the drawings for devices in use or operation. Furthermore, when a layer is referred to as being “between” two layers, it may be the only layer between the two layers, or there may be one or more layers in between.

[0043] It should be noted that the diagrams provided in the present embodiment only schematically illustrate the basic concept of the present application, and only the components related to the present application are shown in the diagrams, rather than being drawn according to the number, shape and size of the components when actually implemented. The actual implementation of each component can be a random change, and the component layout pattern can be more complex. In order to make the diagrams as simple as possible, not all structures are marked in each of the drawings.

[0044] The metal button is used to realize the mutual connection between the electrode sheet and the main machine of the detachable small orthopedic electric stimulation treatment instrument in the prior art, which leads to the increase of the thickness and volume of the whole machine, and causes the problems of inconvenience in use, poor user experience and the like. In view of this, the present inventors have proposed an improvement scheme after long-term research.

[0045] Specifically, as Figs. 1-3The orthopedic electric stimulation therapeutic instrument can stimulate human body by generated electric current to play a physical treatment role. The orthopedic electric stimulation therapeutic instrument comprises a host 11, a base 12, an electrode sheet 13 and a metal conductive cap 14; the host 11 is provided with an electric stimulation generation circuit (not shown) for generating electric stimulation signals and a plurality of first conductive contact points 111, the first conductive contact points 111 are electrically connected with the electric stimulation generation circuit; the base 12 is provided with a base groove 121 and a plurality of conductive probes 122 located in the base groove 121, the electrode sheet 13 is provided with a plurality of second conductive contact points 131, a positive electrode sheet (not shown) and a negative electrode sheet, the positive electrode sheet and the negative electrode sheet are electrically connected with the second conductive contact points 131, the metal conductive cap 14 is provided with a conductive bump 141; the host 11 covers the base groove 121, the first conductive contact points 111 and the conductive probes 122 are electrically contacted one by one, the electrode sheet 13 is located on the surface of the base 12 away from the host 11, the second conductive contact points 131 are sleeved on the conductive probes 122 one by one, the metal conductive cap 14 is arranged on the side of the second conductive contact points 131 away from the host 11 and is sleeved on the conductive probes 122, the conductive bump 141 of the metal conductive cap 14 is electrically contacted with the second conductive contact points 131, that is, the metal conductive cap 14 and the second conductive contact points 131 are overlapped and are sleeved on the conductive probes 122, thereby realizing the electrical connection with the host 11. The improved structure design of the present application utilizes the metal conductive cap with the conductive bump to press on the electrode sheet and is sleeved on the conductive probes of the host together with the conductive contact points on the electrode sheet, so that the electrode sheet, the base and the host are connected as a whole, the conductive bump changes the contact between planes into the contact between a plane and a point, which can make the connection between the electrode sheet and the base more reliable and help to reduce the thickness of the base, so that the overall structure of the orthopedic electric stimulation therapeutic instrument is more compact and the user experience can be further improved. At the same time, the electrode sheet is fixed on the base by the pressing of the metal conductive cap, so that when needed, the electrode sheet can be replaced by removing the metal conductive cap (the metal conductive cap and the electrode sheet can also be replaced at the same time), thereby realizing the recycling of the base and the host, which helps to reduce the use cost and reduce environmental pollution.

[0046] It should be noted that the electrode sheet 13 can exist in various forms such as FPC (Flexible Printed Circuit) and the like, which can be silver-plated on a PVC substrate to form the positive and negative electrode sheets, or can be a pre-made circuit structure transferred to a PVC substrate or the like. In an example, the positive and negative electrode sheets are welded with the second conductive contact point 131 through a low-temperature soldering wire welding process. The specific structure of the electrode sheet 13 can be set as needed, such as in the present embodiment, the electrode sheet 13 includes a first part corresponding to the base groove 121 and a second part electrically connected to the first part and extending to one side, and the second conductive contact point 131 is arranged on the first part. In other examples, the electrode sheet 13 can also include a first part corresponding to the base groove 121 and a second part electrically connected to the first part and extending to both sides, i.e. the first part is located between the two second parts. In an example, the electrode sheet 13 is further provided with a protective structure 132 surrounding the second conductive contact point 131 in the circumferential direction, and the protective structure 132 can be a structure similar to a "Fang" type structure, and the second conductive contact point 131 is located in the "Fang" type structure. In further examples, a groove is formed in the "Fang" type structure, and the second conductive contact point 131 is located in the groove. By providing a groove, the surface of the second conductive contact point 131 does not protrude from the surface of the electrode sheet 13, or in other words, the height of the second conductive contact point 131 is less than the maximum thickness of the electrode sheet 13, and in further examples, when the metal conductive cap 14 is sleeved on the second conductive contact point 131, the surface of the metal conductive cap 14 is flush with the surface of the electrode sheet 13. (In this specification, the concept of "electrical contact" means that two structures are in contact with each other and electrically conductive to each other in a powered state.)

[0047] As an example, the host 11 can be correspondingly provided with a groove, the opening of which faces the base 12, and the first conductive contact point 111 is arranged in the groove (a receiving groove for accommodating the first conductive contact point 111 can be further arranged in the groove), and the host 11 and the base 12 can be fixed to each other by screwing, such as the inner surface of the groove of the host 11 being provided with an internal thread and the outer surface of the base groove 121 being provided with an external thread, so that when the host 11 covers the base 12, the internal thread on the host 11 cooperates with the external thread on the base groove 121. As an example, the host 11 can also be provided with a battery unit and a key unit, the first conductive contact point 111 and the key unit being electrically connected to the battery unit, the battery unit including but not limited to a lithium ion battery and a charging interface electrically connected to the lithium ion battery, thereby further improving the portability of the orthopedic electric stimulation therapeutic instrument.

[0048] In an example, the host 11 is provided with a first magnetic member (not shown) on the surface facing the base groove 121, and the base groove 121 is provided with a second magnetic member (not shown). When the host 11 is covered on the base groove 121, the first magnetic member and the second magnetic member are attracted to each other. For example, the first magnetic member can be an iron sheet and the second magnetic member can be a magnet, or the first magnetic member can be a magnet and the second magnetic member can be an iron sheet. Both the first magnetic member and the second magnetic member can be single or multiple. The magnetic member can make the host 11 and the base groove 121 better fit and fix.

[0049] The number of the first conductive contact point 111, the second conductive contact point 131 and the conductive probe 122 is at least two to ensure that a loop can be formed between the positive electrode sheet and the negative electrode sheet of the electrode sheet 13. In an example, the number of the first conductive contact point 111, the second conductive contact point 131 and the conductive probe 122 is more than three, so that different electrical contact points can be selected according to different needs to realize different circuit conduction and make the orthopedic electrical stimulation therapy instrument in different working modes.

[0050] In an example, the metal conductive cap 14 and the conductive probe 122 are filled with glue to further ensure the connection and fixation of the metal conductive cap 14 and the conductive probe 122. The glue is preferably but not limited to one or a combination of AB glue and conductive glue.

[0051] In an example, the conductive probe 122 is welded to the base 12 by a low-temperature soldering wire welding process.

[0052] The metal conductive cap 14 is similar to a nut and is sleeved on the conductive probe 122. Its structure can be referred to Fig. 3 As shown in the figure, the metal conductive cap 14 is provided with a through hole in the middle, and a support part is surrounded around the through hole, which can be used as a force supporting point during installation. In an example, the conductive protrusions 141 are multiple and uniformly distributed on the same circumferential surface of the support part. The multiple conductive protrusions 141 can further ensure the contact between the metal conductive cap 14 and the second conductive contact point 131. Of course, in other examples, the multiple conductive protrusions 141 can also be connected together to form a conductive convex ring, which is not limited in particular.

[0053] As an example, the orthopedic electrical stimulation therapy instrument further comprises a conductive gel 15, which is covered on the surface of the electrode sheet 13 away from the base 12. The area of the conductive gel 15 is preferably close to the surface area of the electrode sheet 13. The conductive gel 15 can be prepared by coating on the surface of the electrode sheet 13 after the orthopedic electrical stimulation therapy instrument is assembled and dried. Of course, it can also be customized and attached to the surface of the electrode sheet 13.

[0054] The orthopedic electrostimulation therapy device can further comprise a release paper 16 covering the surface of the conductive gel 15 away from the electrode sheet, to protect the conductive gel 15 from being contaminated or damaged, and the release paper 16 can be torn off before using the orthopedic electrostimulation therapy device. The present application also provides an assembling process and method of the orthopedic electrostimulation therapy device as described in any of the above solutions. As described above, the orthopedic electrostimulation therapy device comprises a main machine 11, a base 12, an electrode sheet 13 and a metal conductive cap 14; the main machine 11 is provided with an electrostimulation generation circuit and a plurality of first conductive contact points 111, the first conductive contact points 111 are electrically connected with the electrostimulation generation circuit; the base 12 is provided with a base groove 121 and a plurality of conductive probes 122 in the base groove 121, the electrode sheet 13 is provided with a plurality of second conductive contact points 131, a positive electrode sheet and a negative electrode sheet, the positive electrode sheet and the negative electrode sheet are electrically connected with the second conductive contact points 131, and the metal conductive cap 14 is provided with conductive bumps 141; the assembling process and method comprises the following steps:

[0055] The electrode sheet 13 is placed on the surface of the base 12 away from the main machine 11, and the second conductive contact points 131 are fitted on the conductive probes 122 of the base 12 one by one;

[0056] The metal conductive cap 14 is fitted on the conductive probes 122 from the side of the electrode sheet 13 away from the base 12, and the conductive bumps 141 of the metal conductive cap 14 are in electrical contact with the second conductive contact points 131;

[0057] The metal conductive cap 14 is pressed to make the metal conductive cap 14, the second conductive contact points 131 and the conductive probes 122 in electrical contact;

[0058] The glue, such as conductive glue, is filled to fix the metal conductive cap 14 and the conductive probes 122;

[0059] High-temperature baking is performed to solidify the glue, such as baking in a high-temperature oven;

[0060] The conductive gel 15 is covered on the electrode sheet 13, such as using a coating process to coat the conductive gel on the surface of the electrode sheet 13, and then solidifying and forming, or placing the preformed conductive gel 15 on the surface of the electrode sheet;

[0061] The release paper 16 is covered on the conductive gel 15 to play a protective role, such as preventing the conductive gel 15 from being contaminated or scratched by sharp objects;

[0062] Finally, the main machine 11 is covered on the base groove 121.

[0063] Of course, in other examples, the host 11 and the base 12 can be assembled first, but the final installation of the host 11 and the base 12 can effectively avoid the damage of the circuit in the host 11 caused by subsequent processes, such as subsequent high-temperature baking processes.
