Description

Technical Field

[0001] This invention belongs to the field of thermostat technology, specifically relating to a thermostat that is easy to install. Background Technology

[0002] A thermostat is a common temperature control device for indoor air conditioning, widely used in commercial buildings, hotels, apartments, shops, and residences. Thermostats can be used in every household or every room. Each room user can set a desired temperature value. The thermostat compares the set temperature with the actual room temperature and outputs a signal to control the air conditioner's operation, achieving the goal of maintaining a comfortable room temperature.

[0003] Because the thermostat needs to control the high voltage of the air conditioner, a relay is placed inside the thermostat. The relay controls the high voltage of the air conditioner. The relay is relatively tall, so in order to ensure the aesthetics of the thermostat when installed on the wall, the common practice in the industry is to divide the thermostat into two parts: the control panel and the power box. The control panel has an LCD display and buttons for human-machine interaction; the power box contains several relays for controlling the high voltage of the air conditioner.

[0004] In actual installation, the power supply box is first installed on a standard 86-type wall junction box. Then, a ribbon cable is used to electrically connect the power supply box to the control panel. Finally, the control panel is fixed to the hooks on the power supply box to complete the installation. However, due to the small size of the thermostat and insufficient internal space, a very short ribbon cable is required for the electrical connection between the power supply box and the control panel. This makes it inconvenient to plug in this ribbon cable during on-site installation, easily leading to problems such as improper insertion, looseness, poor contact, and reverse insertion, which can easily cause potential problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a thermostat that is easy to install.

[0006] The present invention is implemented as follows: A thermostat that is easy to install includes a detachable control panel and a power supply box. The control panel includes a first base, in which an operation circuit board (PCBA) assembly is disposed. The operation circuit board (PCBA) assembly has a first connector protruding from the first base. The power supply box includes a second base, in which a power supply (PCBA) assembly is disposed. The power supply (PCBA) assembly has a second connector protruding from the second base. A connector pin assembly protruding from the second base is movably connected to the second connector pin assembly. An assembly gap is formed between the connector pin assembly and both the second connector pin assembly and the second base. The first connector pin assembly has a plurality of pin holes adapted to the connector pin assembly. The connector pin assembly automatically adjusts the positional deviation between itself and the plurality of pin holes through the assembly gaps. When the connector pin assembly is connected to the plurality of pin holes, an electrical connection is achieved between the control panel and the power supply box.

[0007] Furthermore, the first base includes a rear shell, an annular frame, and a cover plate connected in sequence. The operating circuit board PCBA assembly is disposed within the space enclosed by the rear shell, the annular frame, and the cover plate. The rear shell is provided with a slot corresponding to the first connecting pin.

[0008] Furthermore, the height of the first connecting nut is less than the depth of the slot.

[0009] Furthermore, the second base includes a rear frame and a front shell connected in sequence. The power PCBA assembly is disposed in the space enclosed by the rear frame and the front shell. The front shell is provided with a protrusion that can be embedded in the slot. The protrusion is positioned corresponding to the position of the second connector pin. The connector pin assembly is connected to the first connector pin through the protrusion.

[0010] Furthermore, the protrusion has a through hole, a partition is provided in the through hole, and a plurality of positioning holes are provided on the partition. The pin seat part of the connecting pin assembly is located between the second connecting pin and the partition. One end of the pin insertion part of the connecting pin assembly is inserted into the second connecting pin, and the other end extends out of the positioning hole.

[0011] Furthermore, the diameter of the positioning hole is greater than the thickness of the pin portion of the connecting pin header.

[0012] Furthermore, the length of the pin portion extending out of the positioning hole of the connecting pin assembly is less than the distance between the end face of the partition and the protrusion.

[0013] Furthermore, the gap between the needle seat portion of the connecting needle assembly and the second connecting pin, and the gap between the needle seat portion of the connecting needle assembly and the partition plate are both assembly gaps.

[0014] Furthermore, the rear shell is provided with several magnets, and the front shell is provided with an iron hanging plate that is compatible with the magnets. The magnets and the iron hanging plate cooperate to fix the operation panel and the power box.

[0015] Furthermore, the iron hanging plate is provided with an upper hook and a lower hook on both sides, and the rear shell is provided with an upper hanging groove that matches the upper hook and a lower hanging groove that matches the lower hook.

[0016] This invention provides an easy-to-install thermostat that electrically connects the control panel and the power supply box via a movable connecting pin. The assembly gap provides space for position adjustment of the connecting pin, accommodating positional deviations during installation and ensuring a reliable electrical connection. This solves the problem of difficult on-site installation encountered in the thermostat industry, making the installation process between the control panel and the power supply box quick, convenient, and reliable.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] Please see Figures 1-6 This invention discloses an easy-to-install thermostat, comprising a detachable operation panel 1 and a power supply box 2. The operation panel 1 includes a first base 11, within which an operation circuit board (PCBA) assembly 12 is disposed. The PCBA assembly 12 has a first connecting nut 13 extending out of the first base 11. The PCBA assembly 12 serves for electrical control and human-machine interface interaction. Specifically, the first base 11 includes a rear shell 111, an annular frame 112, and a cover plate 113 connected in sequence. The PCBA assembly 12 is disposed within the space enclosed by the rear shell 111, the annular frame 112, and the cover plate 113. The cover plate 113 is preferably a transparent panel, serving as a viewing window for the displayed content and protecting the components on the PCBA assembly 12 from damage by external mechanical factors. The rear shell 111 has a slot 114 corresponding to the first connecting nut 13, with a portion of the first connecting nut 13 extending into the slot 114.

[0028] The power supply box 2 includes a second base 21, within which a power PCBA assembly 22 is housed. The power PCBA assembly 22 is specifically used for high / low voltage conversion and relay assembly. The power PCBA assembly 22 has a second connector nut 24, on which a connector pin assembly 23 extending out of the second base 21 is movably connected. Typically, the connector pin assembly 23 has a pin holder and several pins. Assembly gaps 25 are formed between the connector pin assembly 23, the second connector nut 24, and the second base 21. Specifically, the second base 21 includes a rear frame 211 and a front shell 212 connected in sequence. The power PCBA assembly 22 is disposed within the space enclosed by the rear frame 211 and the front shell 212. The front shell 212 has a protrusion 213 that can be embedded into the slot 114. The protrusion 213 corresponds to the position of the second connector nut 24, and the connector pin assembly 23 is connected to the first connector nut 13 via the protrusion 213. Specifically, the protrusion 213 has a through hole 214, and part of the second connecting pin 24 extends into the through hole 214. A partition 215 is provided in the through hole 214, and the partition 215 has a plurality of positioning holes 216. The pin seat part of the connecting pin assembly 23 is located between the second connecting pin 24 and the partition 215. One end of the pin part of the connecting pin assembly 23 is inserted into the second connecting pin 24, and the other end extends out of the positioning hole 216. The first connecting pin 13 has a plurality of pin holes 131 that are adapted to the connecting pin assembly 23. That is, the pin part extending out of the positioning hole 216 can realize the electrical connection between the operation panel 1 and the power box 2 by embedding it into the pin hole 131.

[0029] The gap between the pin seat portion of the connecting pin assembly 23 and the second connecting nut 24, and the gap between the pin seat portion of the connecting pin assembly 23 and the partition 215 are both assembly gaps 25. These two assembly gaps 25 provide space for adjusting the position of the connecting pin assembly 23. When connecting the operation panel 1 and the power box 2, aligning the protrusion 213 with the slot 114 allows the pin portion of the connecting pin assembly 23 to be inserted into the pin hole 131 of the first connecting nut 13. During this process, factors such as manufacturing process deviations, on-site installation environmental factors, and the skill level of the personnel can affect the final result. Due to a combination of factors, the pin portion may experience a positional deviation from the pin hole 131. When this deviation occurs, the connecting pin assembly 23 automatically adjusts itself via the assembly gap 25. This means the pin portion can automatically swing in multiple dimensions, such as up, down, left, and right, to adapt to the position of the pin hole 131. To prevent the positioning hole 216 from restricting the swing of the pin portion, the diameter of the positioning hole 216 is larger than the thickness of the pin portion of the connecting pin assembly. This avoids installation failures caused by the pin portion not being properly inserted into the pin hole 131, resulting in faster installation and a reliable electrical connection between the operation panel 1 and the power supply box 2.

[0030] Furthermore, the height of the first connecting nut 13 is less than the groove depth of the slot 114, and the length of the pin portion extending out of the positioning hole 216 is less than the distance between the end faces of the partition 215 and the protrusion 213. That is, during the electrical connection process, the protrusion 213 and the slot 114 make contact and engage beforehand; that is, the protrusion 213 and the slot 114 engage first, and then the pin portion engages with the pin hole 131, serving a guiding function.

[0031] Preferably, for the detachable connection between the operation panel 1 and the power box 2, the rear shell 111 is provided with a plurality of magnets 115, and the front shell 212 is provided with an iron hanging plate 217 adapted to the magnets 115. The magnets 115 and the iron hanging plate 217 cooperate to fix the operation panel 1 and the power box 2. Further, the iron hanging plate 217 is provided with an upper hook 218 and a lower hook 219 on both sides, and the rear shell 111 is provided with an upper hanging groove 116 adapted to the upper hook 218 and a lower hanging groove 117 adapted to the lower hook 219. During on-site installation, the upper hanging slot 116 on the operation panel 1 is hooked onto the upper hook 218 on the power box 2. A light press on the operation panel 1 causes the lower hanging slot 117 on the operation panel 1 to automatically align and hook onto the lower hook 219 on the power box 2 through the mutual attraction between the magnet 115 and the iron hanging plate 217. Simultaneously, the first connecting pin 13 on the operation panel 1 and the connecting pin assembly 23 on the power box 2 will also automatically align and reliably connect through the assembly gap 25. The entire installation process is quick, convenient, and reliable.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
