[0002] A handheld wireless pulse generator is a portable electronic device used to generate pulse signals. The generation and transmission of these pulse signals can be controlled wirelessly. Compared to wired pulse generators, handheld wireless pulse generators offer advantages in portability and flexibility, making them suitable for applications requiring flexible operation and remote control.

[0003] Existing wireless pulse generators generally include a shell, in which a control panel and components such as a battery are installed. The control panel has a wireless transmission function. The operating surface of the shell is provided with control components such as a handwheel, an emergency button, and a switch. When in use, signals are transmitted to the control panel through the control components, and the control panel transmits the signals wirelessly to related equipment, thereby achieving the purpose of wireless remote control.

[0004] However, the existing wireless pulse generator still has the following shortcomings during use:

[0005] A handheld wireless pulse generator may be accidentally dropped during use, and the control components of existing handheld wireless generators are generally exposed outside the shell, which makes it easy for the control components to be damaged or malfunction after the generator is dropped or bumped.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1:

[0034] See also Figures 1 to 6 In an embodiment of the present invention, a wireless handheld pulse generator includes a housing 1, a power switch 20 is provided at one end of the housing 1, an antenna 24 is provided at the other end, a pulse wheel 19, an axis switch 22, a rate switch 23 and an emergency button 21 are installed on the front of the housing 1, a control module and a battery are installed in the housing 1, and the pulse wheel 19, the power switch 20, the emergency button 21, the axis switch 22, the rate switch 23 and the antenna 24 are all electrically connected to the control module;

[0035] A first protective mechanism is provided on the front of the housing 1, and a second protective mechanism is provided on both sides of the housing 1. A transmission assembly is provided between the second protective mechanism and the first protective mechanism;

[0036] Fixing seats 18 are fixedly mounted on the bottom surface of the housing 1 near both ends. The fixing seats 18 are used to mount the second protection mechanism.

[0037] The control module generally consists of a control board, a circuit board, and a single-chip microcomputer. The circuit board houses a photoelectric converter for receiving, transmitting, and converting optical signals. Hardware filtering devices are also installed on the circuit board to filter out clutter and interference signals to ensure proper functioning of the device and improve signal stability. The single-chip microcomputer is the core controller of a handheld wireless pulse generator, responsible for controlling various functions and parameters. The single-chip microcomputer is typically integrated into the device's main control board, serving as the central control unit for processing and executing user commands while communicating with other components. Therefore, the control module of a wireless pulse generator is currently available.

[0038] The first protection mechanism includes a support rod 3. Extension plates 2 are fixedly connected to the periphery of the housing 1 near the corners. A support rod 3 is vertically fixedly installed on the top surface of the extension plate 2 at the end away from the housing 1. A guide rod 4 is fixedly connected between the top ends of the two support rods 3 at the same end. Two protection plates 6 are arranged between the two guide rods 4 and are symmetrically distributed about the middle position of the guide rods 4.

[0039] The end surfaces of the two protective plates 6 are fixedly mounted with protrusions 7 at the adjacent ends, and the protrusions 7 are slidably connected to the guide rod 4 brackets at the corresponding positions;

[0040] A spring 5 is fixedly connected between the protrusion 7 and the top of the support rod 3 on the same side and is sleeved on the outer periphery of the guide rod 4;

[0041] A connecting block 25 is fixedly installed on the bottom surface of the two protective plates 6 at the middle position of the adjacent side.

[0042] The transmission assembly includes a rope 10 and a mounting base 8 fixedly mounted in the middle of the top side of the housing 1, and a guide wheel 9 aligned with the connecting block 25 is rotatably mounted in the mounting base 8;

[0043] Below the mounting seat 1 8 is a mounting seat 2 14 fixedly mounted in the middle position of the bottom side of the housing 1. A winding wheel 15 is rotatably mounted in the mounting seat 2 14. One end of the winding wheel 15 rotates through the mounting seat 2 14 and is fixedly mounted with a gear 16.

[0044] One end of the rope 10 is fixedly connected to the periphery of the winding wheel 15, and the other end of the rope 10 is fixedly connected to the connecting block 25 on the bottom surface of the protective plate 6 at the corresponding side position after passing around the guide wheel 9.

[0045] The second protection mechanism includes a second protection plate 11, and elastic telescopic rods 13 are fixedly connected to both ends of the inner side of the second protection plate 11. The ends of the two elastic telescopic rods 13 away from the second protection plate 11 are fixedly connected to two fixing seats 18 respectively.

[0046] A rack 17 is fixedly connected to the middle portion of the inner side surface of the second protective plate 11 , and the rack 17 is engaged with the gear 16 in the transmission assembly on the corresponding side.

[0047] When the utility model is in use:

[0048] When not in use, the two protective plates 6 maintain elastic extrusion contact under the elastic force of the spring 5, thereby protecting and blocking the operating surface of the shell 1; and at this time, the rope 10 is in a taut state, and the elastic telescopic rod 13 is in a fully extended state.

[0049] When in use, the user holds the device in his hand and then applies force to hold it on both sides; during the process, after the protective plate 2 11 in the two sets of second protective mechanisms is subjected to force, the elastic telescopic rod 13 contracts, and at the same time the rack 17 moves synchronously toward the direction close to the shell 1. During the movement of the shell 1, the winding wheel 15 is driven to rotate through engagement with the gear 16, and the rotation of the winding wheel 15 winds the rope 10, thereby pulling the two protective plates 1 6 on the guide rod 4 to slide away from each other through the fixed connection between the rope 10 and the connecting block 25. The gap formed between the two protective plates 1 6 exposes the operating surface of the shell 1, and the user can operate the control component with the other hand.

[0050] When the device accidentally falls, the gripping force on the device disappears. At this time, under the action of the restoring elastic force of the spring 5 and the elastic telescopic rod 13, the two protective plates 16 will automatically reset and slide on the guide rod 4 to squeeze contact, thereby returning to the state of blocking and protecting the operating surface of the shell 1; therefore, when the shell 1 is impacted, the two protective plates 16 can block and protect the control components, effectively reducing the possibility of damage and malfunction of the control components; at the same time, the protective plates 2 11 on both sides of the shell 1 also have the function of blocking and protecting, further improving the protection performance of the shell 1.

[0051] Therefore, the present invention can provide protection when the device is not in use through the coordinated arrangement of the first protection mechanism, the second protection mechanism and the transmission assembly, and automatically restore to the protection state in the first time in the event of a fall, thereby providing effective protection for the control components on the operating surface of the shell 1.

[0052] Example 2:

[0053] See also Figure 1 On the basis of Example 1, a rubber pad 12 is fixedly installed on the outer side of the protective plate 11.

[0054] The provision of the rubber pad 12 improves the comfort of the user in the force application process, and also increases the friction of the protective plate 2 11, thereby reducing the possibility of the utility model falling during use.

[0055] Example 3:

[0056] On the basis of embodiment 1, the support rod 3 is a damping elastic telescopic rod.

[0057] The provision of the damping elastic telescopic rod enables the first protection component to not only protect the control component but also to provide a certain buffering effect on the impact force received, thereby further improving the protection effect of the utility model.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
