Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention.

[0029] Example 1

[0030] Reference Figure 1 to Figure 7 , which is the first embodiment of the utility model, and this embodiment provides an electromagnetic compatibility test radio frequency environment simulation device, which includes a main body component 100 and a support component 200. Through the cooperation of the two, the heat sink 103 can adjust the heat dissipation capacity of the radio frequency signal generator, and can adjust the direction of the radio frequency signal generator operation interface, so that people of different heights can operate the radio frequency signal generator operation interface. At the same time, the heat dissipation capacity of the heat sink 103 can be adjusted through the support component 200.

[0031] Specifically, the main assembly 100 includes a signal generator body 101 , a support leg 102 and a heat sink 103 . The support leg 102 is fixed to the bottom of the signal generator body 101 , and the heat sink 103 is disposed at the bottom of the signal generator body 101 .

[0032] The signal generator body 101 is the main body of the radio frequency signal generator, which is a device for generating radio frequency signals, and is usually used to simulate electromagnetic environment and interference, and to perform electromagnetic compatibility testing. The support foot 102 is used to support the signal generator body 101, and the heat sink 103 is used to adjust the ability of the signal generator body 101 to discharge heat, thereby adjusting the heat dissipation capacity of the signal generator body 101. The radio frequency signal generator generates a large amount of heat when working. If the heat cannot be effectively dissipated, it may affect the performance and life of the signal generator. The existing radio frequency signal generator basically uses a fan to bring out the heat in the radio frequency signal generator. Since the existing air outlets are mostly fixed grids, when the heat generated by the radio frequency signal generator is large, the existing air outlets cannot discharge the heat in time. At this time, the heat sink 103 can be used to increase the ability of the radio frequency signal generator to discharge hot air, thereby enhancing the heat dissipation capacity of the radio frequency signal generator.

[0033] The support assembly 200 is disposed at the bottom of the signal generator body 101 and includes a support member 201 , an adjustment member 202 and a positioning member 203 . The support member 201 is disposed in the heat sink 103 , the adjustment member 202 is located in the support member 201 , and the positioning member 203 is located on one side of the support member 201 .

[0034] The support member 201 is used to support the signal generator body 101 and adjust the angle of the signal generator body 101, thereby adjusting the angle of the operation interface on the signal generator body 101, so that the angle of the operation interface can adapt to people of different heights. The adjustment member 202 is used to adjust the position of the support member 201, and the positioning member 203 is used to fix the position of the support member 201. At the same time, the positioning member 203 can support the position of the heat sink 103.

[0035] Specifically, the heat sink 103 includes a supporting shell 103 a and a supporting column 103 b . The supporting shell 103 a is fixed to the bottom of the signal generator body 101 , and the supporting column 103 b is fixed to one side of the supporting shell 103 a .

[0036] The supporting shell 103a is used to support the supporting column 103b, and there are two supporting shells 103a and two supporting columns 103b.

[0037] Specifically, the heat sink 103 further includes a support sleeve 103c and a sealing plate 103d. The support sleeve 103c is rotatably connected to the surface of the support column 103b, and the sealing plate 103d is fixed to one side of the support sleeve 103c.

[0038] There are two support sleeves 103c, which are symmetrically arranged on both sides of the sealing plate 103d, and are used to support the sealing plate 103d so that the sealing plate 103d can rotate with the support column 103b as the center. When the sealing plate 103d is opened, the ability of the signal generator body 101 to discharge hot air can be increased, thereby increasing the heat dissipation capacity of the signal generator body 101.

[0039] Specifically, the heat sink 103 further includes a support shaft 103e and a limiting column 103f. The support shaft 103e is fixed to the bottom of the signal generator body 101, and the limiting column 103f is rotatably connected to the surface of the support shaft 103e.

[0040] The support shaft 103e is used to support the limiting column 103f, and the limiting column 103f is used to limit the sealing plate 103d.

[0041] Example 2

[0042] Reference Figure 3 to Figure 6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0043] Specifically, the support member 201 includes a sliding sleeve 201a and a support rod 201b. The sliding sleeve 201a slides in the support shell 103a, and the support rod 201b is fixed on the surface of the sliding sleeve 201a.

[0044] The sliding sleeve 201 a is used to position the support rod 201 b . There are two support rods 201 b for supporting the signal generator body 101 .

[0045] Specifically, the support member 201 further includes a connecting rod 201c and a friction rod 201d. The connecting rod 201c is fixed to one side of the support rod 201b, and the friction rod 201d is fixed to one side of the connecting rod 201c.

[0046] The connecting rod 201c is used to connect the ends of the two supporting rods 201b together, so as to increase the stability of the supporting rods 201b. The friction rod 201d is supported by a rubber material to prevent the friction rod 201d from sliding on the desktop.

[0047] Example 3

[0048] Reference Figure 3 to Figure 7 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0049] Specifically, the adjusting member 202 includes a plug post 202a, a first spring 202b and a push plate 202c. The plug post 202a slides in the sleeve 201a. The end of the first spring 202b is fixed to the inner wall of the plug post 202a. The push plate 202c is fixed to the end of the plug post 202a.

[0050] Two plug posts 202a are provided in each sliding sleeve 201a, and a plurality of positioning grooves are provided in the supporting shell 103a. The plug posts 202a are inserted into the positioning grooves of the supporting shell 103a to fix the position of the sliding sleeve 201a. The first spring 202b is in a compressed state, so that the two plug posts 202a will not be separated from the positioning grooves in the supporting shell 103a. The push plate 202c is used to drive the plug posts 202a to move out of the positioning grooves in the supporting shell 103a, and a slope is provided on the end of the push plate 202c.

[0051] Specifically, the adjusting member 202 further includes an extrusion rod 202d and an extrusion block 202e. The extrusion rod 202d slides in the supporting rod 201b, and the extrusion block 202e is fixed to the inner wall of the extrusion rod 202d.

[0052] The extrusion rod 202d is used to extrude the inclined surfaces at the ends of the two push plates 202c, so that the two push plates 202c are close to each other, so that the two plug posts 202a are moved out of the positioning grooves in the support shell 103a. There are two extrusion blocks 202e in each extrusion rod 202d, which are used to extrude the push plates 202c and increase the moving stroke of the push plates 202c.

[0053] Specifically, the adjusting member 202 further includes a second spring 202f and a driving block 202g. Two ends of the second spring 202f are respectively fixed to the end of the extrusion rod 202d and the inner wall of the support rod 201b. The driving block 202g is fixed to one side of the extrusion rod 202d.

[0054] The second spring 202f is in a stretched state, and by pulling the driving block 202g, the squeezing rod 202d can be driven to move toward the push plate 202c, thereby squeezing the push plate 202c. When the driving block 202g is released, the squeezing rod 202d can be reset and moved away from the push plate 202c under the reset pulling force of the second spring 202f.

[0055] Specifically, the positioning member 203 includes a positioning rod 203a, a connecting sleeve 203b, a driving column 203c and a positioning plate 203d. The positioning rod 203a is rotatably connected to one side of the support shell 103a through a rotating shaft, the connecting sleeve 203b is fixed to one side of the positioning rod 203a, the driving column 203c is fixed to one side of the support rod 201b, and the positioning plate 203d is fixed to one side of the positioning rod 203a.

[0056] The positioning rod 203a is rotatably connected to one side of the support shell 103a through a rotating shaft, so that the positioning rod 203a can rotate freely on one side of the support shell 103a. When the support rod 201b moves, the connecting sleeve 203b can be driven to move through the driving column 203c, so that the connecting sleeve 203b drives the positioning rod 203a to rotate, so that the positioning rod 203a supports the support rod 201b. The positioning plate 203d is used to support the sealing plate 103d. When the rotation angle of the positioning rod 203a is larger, the sealing plate 103d can be opened at a larger angle, so that the heat dissipation capacity of the signal generator body 101 is stronger.

[0057] During use, when it is necessary to adjust the angle of the signal generator body 101, the two driving blocks 202g are moved at the same time, and the driving block 202g can drive the extrusion rod 202d to move toward the push plate 202c, thereby squeezing the push plate 202c, and at the same time, the extrusion block 202e in the extrusion rod 202d will squeeze the push plate 202c, increasing the movement stroke of the push plate 202c, so that the push plate 202c drives the plug column 202a to move out of the positioning groove in the support shell 103a, thereby releasing the limit on the sliding sleeve 201a, and the position and angle of the support rod 201b can be adjusted at this time. When adjusting the position and angle of the support rod 201b, the connecting sleeve 203b can be driven to move by the driving column 203c, so that The connecting sleeve 203b drives the positioning rod 203a to rotate, thereby moving the positioning rod 203a. When the position of the support rod 201b is determined, the driving block 202g is released. Under the reset tension of the second spring 202f, the extrusion rod 202d can be reset and moved away from the push plate 202c. Through the reset elastic force of the first spring 202b, the two plugs 202a are inserted into the positioning grooves of the support shell 103a, thereby limiting the sliding sleeve 201a again. At this time, the support rod 201b is fixed by the support of the positioning rod 203a, thereby providing stable support for the signal generator body 101, so that the operation panel of the signal generator body 101 is at a suitable operating angle.

[0058] When the heat dissipation capacity of the signal generator body 101 needs to be adjusted, the limiting column 103f can be rotated to make the limiting column 103f move away from the sealing plate 103d, thereby releasing the limiting of the sealing plate 103d. At this time, one end of the sealing plate 103d can fall on the top of the positioning plate 203d on one side of the positioning rod 203a, so as to support the sealing plate 103d. By opening the sealing plate 103d, the discharge capacity of the signal generator body 101 for hot air can be improved, thereby enhancing the heat dissipation capacity of the signal generator body 101. At the same time, the rotation angle of the positioning rod 203a controls the opening angle of the sealing plate 103d, thereby controlling the heat dissipation capacity of the signal generator body 101, so that the heat dissipation capacity of the heat dissipation window can be adjusted according to the heat dissipation requirements.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
